Recent progresses using state-of-the-art experimental techniques have
motivated a number of new insights on heavy fermion physics. This article gives
a brief summary of the author's research along this direction. We discuss five
major topics including: (1) Development of phase coherence and two-stage
hybridization; (2) Two-fluid behavior and hidden universal scaling; (3) Quantum
phase transitions and fractionalized heavy fermion liquid; (4) Quantum critical
superconductivity; (5) Material-specific properties. These cover the most
essential parts of heavy fermion physics and lead to an emerging global picture
beyond conventional theories based on mean-field or local approximations.

The phrase "more is different" is often used to refer to the new, unexpected
collective phenomena that can arise when the number of states in a given system
is large. In this contribution to the Snowmass 2021 Study, we describe 13
unexpected collective phenomena that can arise when the dark sector contains a
large number of states, contrary to the usual assumptions. These 13 take-away
lessons stretch across all of the domains of relevance for dark-matter physics,
including collider signatures, direct-detection signatures, indirect-detection
signatures, new perspectives on dark-matter complementarity, and even
unexpected astrophysical and cosmological phenomena that transcend those
normally associated with single-component dark-matter scenarios. These lessons
-- and the phenomena on which they are based -- thereby illustrate the need to
maintain a broad perspective when contemplating the possible signatures and
theoretical possibilities associated with non-minimal dark sectors.

This paper analyzes the structure of mixed-strategy equilibria for Colonel
Blotto games, where the outcome on each battlefield is a polynomial function of
the difference between the two players' allocations. This paper severely
reduces the set of strategies that needs to be searched to find a Nash
equilibrium. It finds that there exists a Nash equilibrium where both players'
mixed strategies are discrete distributions, and it places an upper bound on
the number of points in the supports of these discrete distributions.

We construct an approximate solution for an asymptotically flat, neutral,
thin rotating black ring in any dimension D>=5 by matching the near-horizon
solution for a bent boosted black string, to a linearized gravity solution away
from the horizon. The rotating black ring solution has a regular horizon of
topology S^1 x S^{D-3} and incorporates the balancing condition of the ring as
a zero-tension condition. For D=5 our method reproduces the thin ring limit of
the exact black ring solution. For D>=6 we show that the black ring has a
higher entropy than the Myers-Perry black hole in the ultra-spinning regime. By
exploiting the correspondence between ultra-spinning black holes and black
membranes on a two-torus, we take steps towards qualitatively completing the
phase diagram of rotating blackfolds with a single angular momentum. We are led
to propose a connection between MP black holes and black rings, and between MP
black holes and black Saturns, through merger transitions involving two kinds
of `pinched' black holes. More generally, the analogy suggests an infinite
number of pinched black holes of spherical topology leading to a complicated
pattern of connections and mergers between phases.

We study the effect of a boost (Fermi sea displaced by a finite momentum) on
one dimensional systems of lattice fermions with short-ranged interactions. In
the absence of a boost such systems with attractive interactions possess
algebraic superconducting order. Motivated by physics in higher dimensions, one
might naively expect a boost to weaken and ultimately destroy
superconductivity. However, we show that for one dimensional systems the effect
of the boost can be to strengthen the algebraic superconducting order by making
correlation functions fall off more slowly with distance. This phenomenon can
manifest in interesting ways, for example, a boost can produce a Luther- Emery
phase in a system with both charge and spin gaps by engendering the destruction
of the former.

We show that discrete quasiprobability distributions defined via the discrete
Heisenberg-Weyl group can be obtained as discretizations of the continuous
$SU(N)$ quasiprobability distributions. This is done by identifying the
phase-point operators with the continuous quantisation kernels evaluated at
special points of the phase space. As an application we discuss the positive-P
function and show that its discretization can be used to treat the problem of
diverging trajectories. We study the dissipative long-range transverse-field
Ising chain and show that the long-time dynamics of local observables is well
described by a semiclassical approximation of the interactions.

The data of the experiment of Schiller et al., Phys. Rev. Lett. 77 (1996)
2933, are alternatively evaluated using the maximum likelihood estimation. The
given data are fitted better than by the standard deterministic approach.
Nevertheless, the data are fitted equally well by a whole family of states.
Standard deterministic predictions correspond approximately to the envelope of
these maximum likelihood solutions.

Analog Physical-Layer Relay Attacks with Application to Bluetooth and

Today, we use smartphones as multi-purpose devices that communicate with
their environment to implement context-aware services, including asset
tracking, indoor localization, contact tracing, or access control. As a
de-facto standard, Bluetooth is available in virtually every smartphone to
provide short-range wireless communication. Importantly, many Bluetooth-driven
applications such as Phone as a Key (PaaK) for vehicles and buildings require
proximity of legitimate devices, which must be protected against unauthorized
access. In earlier access control systems, attackers were able to violate
proximity-verification through relay station attacks. However, the
vulnerability of Bluetooth against such attacks was yet unclear as existing
relay attack strategies are not applicable or can be defeated through wireless
distance measurement. In this paper, we design and implement an analog
physical-layer relay attack based on low-cost off-the-shelf radio hardware to
simultaneously increase the wireless communication range and manipulate
distance measurements. Using our setup, we successfully demonstrate relay
attacks against Bluetooth-based access control of a car and a smart lock.
Further, we show that our attack can arbitrarily manipulate Multi-Carrier
Phase-based Ranging (MCPR) while relaying signals over 90 m.

We calculate the van der Waals friction between two semi-infinite solids in
normal relative motion and find a drastic difference in comparison with the
parallel relative motion. The case of the good conductors is investigated in
details both within the local optic approximation, and using a non-local optic
dielectric approach. We show that the friction may increase by many order of
magnitude when the surfaces are covered by adsorbates, or can support
low-frequency surface plasmons. In this case the friction is determined by
resonant photon tunneling between adsorbate vibrational modes, or surface
plasmon modes. The theory is compared to atomic force microscope experimental
data.

Deep Learning of Appearance Models for Online Object Tracking

This paper introduces a novel deep learning based approach for vision based
single target tracking. We address this problem by proposing a network
architecture which takes the input video frames and directly computes the
tracking score for any candidate target location by estimating the probability
distributions of the positive and negative examples. This is achieved by
combining a deep convolutional neural network with a Bayesian loss layer in a
unified framework. In order to deal with the limited number of positive
training examples, the network is pre-trained offline for a generic image
feature representation and then is fine-tuned in multiple steps. An online
fine-tuning step is carried out at every frame to learn the appearance of the
target. We adopt a two-stage iterative algorithm to adaptively update the
network parameters and maintain a probability density for target/non-target
regions. The tracker has been tested on the standard tracking benchmark and the
results indicate that the proposed solution achieves state-of-the-art tracking
results.

When we study the paradoxes of set theory we find out that there are mainly 2
types: the pathologies and the antinomies. These 2 notions are made precise and
compared with the somehow inductively definable concept "abnormal". (See my
paper "Naive Axiomatic Mengenlehre for Experiments" in arXiv.) In the following
5 Patho Theses are discussed in order to formalize this notion of pathology.
This allows us to define formally the property "Hereditary-non-Pathological"
for well-formed formulas. With this property the system NACT* of Naive
Axiomatic Class Theory is constructed, which has a "unique maximal" universe
(in a special sense).

A study is made of a sample of 58 dust-enshrouded Asymptotic Giant Branch
(AGB) stars (including 2 possible post AGB stars), of which 27 are carbon-rich
and 31 are oxygen-rich. These objects were originally identified by Jura &
Kleinmann as nearby (within about 1 kpc of the sun) AGB stars with high
mass-loss rates, greater than 1E-6 solar masses per year. Ground-based
near-infrared photometry, data obtained by IRAS and kinematic data from the
literature are combined to investigate the properties of these stars. The light
amplitude in the near-infrared is found to be correlated with period, and this
amplitude decreases with increasing wavelength. Statistical tests show that
there is no reason to suspect any difference in the period distributions of the
carbon- and oxygen-rich stars for periods less than 1000 days, and no
carbon-rich star has a period longer than 1000 days. The colours are consistent
with those of cool stars with evolved circumstellar dust-shells. Luminosities
and distances are estimated using a period-luminosity relation. Mass-loss
rates, estimated from the 60 micron fluxes, show a correlation with pulsation
period and is tightly correlated with the K-[12] colour. The kinematics and
scale-height of the sample shows that the sources with periods less than 1000
days must have low mass main-sequence progenitors. It is argued that the three
oxygen-rich stars with periods over 1000 days probably had intermediate mass
main-sequence progenitors with remaining stars having an average progenitor
mass of about 1.3 solar masses. The average lifetime of stars in this phase is
estimated to be about 4.0E4 years, indicating they will undergo at most one
more thermal pulse before leaving the AGB.

It is still challenging to control dynamic self-organization patterns of
self-propelled particles. Although varieties of patterns associated with
chirality have been observed, essential control factors determining patterns
remain unclear. Here, we explore numerically how torque upon particle collision
affects dynamic self-organization. Based on the particle-based model with both
collision-induced torque and torque in self-propulsion, we find that
introducing collision-induced torque turns homogeneous bi-polar orientation
templated by bi-directional alignment into rotating mono-polar flocks.

Kamihara and coworkers' report of superconductivity at Tc = 26 K in
fluorine-doped LaFeAsO inspired a worldwide effort to understand the nature of
the superconductivity in this new class of compounds. These iron pnictide and
chalcogenide (FePn/Ch) superconductors have Fe electrons at the Fermi surface,
plus an unusual Fermiology that can change rapidly with doping, which lead to
normal and superconducting state properties very different from those in
standard electron-phonon coupled 'conventional' superconductors. Clearly
superconductivity and magnetism/magnetic fluctuations are intimately related in
the FePn/Ch - and even coexist in some. Open questions, including the
superconducting nodal structure in a number of compounds, abound and are often
dependent on improved sample quality for their solution. With Tc values up to
56 K, the six distinct Fe-containing superconducting structures exhibit complex
but often comparable behaviors. The search for correlations and explanations in
this fascinating field of research would benefit from an organization of the
large, seemingly disparate data set. This review attempts to provide an
overview, using numerous references, with a focus on the materials and their
superconductivity.

In this paper we analyze the approximation of multivariate integrals over the
Euclidean plane for functions which are analytic. We show explicit upper bounds
which attain the exponential rate of convergence. We use an infinite grid with
different mesh sizes and lengths in each direction to sample the function, and
then truncate it. In our analysis, the mesh sizes and the truncated domain are
chosen by optimally balancing the truncation error and the discretization
error.
This paper derives results in comparable function space settings, extended to
$\R^s$, as which were recently obtained in the unit cube by Dick, Larcher,
Pillichshammer and Wo{\'z}niakowski (2011).
They showed that both lattice rules and regular grids, with different mesh
sizes in each direction, attain exponential rates, hence motivating us to
analyze only cubature formula based on regular meshes.
We further also amend the analysis of older publications, e.g., Sloan and
Osborn (1987) and Sugihara (1987), using lattice rules on $\R^s$ by taking the
truncation error into account and extending them to take the anisotropy of the
function space into account.

The HERAPDF2.0 ensemble of parton distribution functions (PDFs) was
introduced in 2015. The final stage is presented, a
next-to-next-to-leading-order (NNLO) analysis of the HERA data on inclusive
deep inelastic $ep$ scattering together with jet data as published by the H1
and ZEUS collaborations. A perturbative QCD fit, simultaneously of
$\alpha_s(M_Z^2)$ and and the PDFs, was performed with the result
$\alpha_s(M_Z^2) = 0.1156 \pm 0.0011~{\rm (exp)}~ ^{+0.0001}_{-0.0002}~ {\rm
(model}$ ${\rm +~parameterisation)}~ \pm 0.0029~{\rm (scale)}$. The PDF sets of
HERAPDF2.0Jets NNLO were determined with separate fits using two fixed values
of $\alpha_s(M_Z^2)$, $\alpha_s(M_Z^2)=0.1155$ and $0.118$, since the latter
value was already chosen for the published HERAPDF2.0 NNLO analysis based on
HERA inclusive DIS data only. The different sets of PDFs are presented,
evaluated and compared. The consistency of the PDFs determined with and without
the jet data demonstrates the consistency of HERA inclusive and jet-production
cross-section data. The inclusion of the jet data reduced the uncertainty on
the gluon PDF. Predictions based on the PDFs of HERAPDF2.0Jets NNLO give an
excellent description of the jet-production data used as input.

The heavy ion (HI) program at the LHC has proven to be a successful and
indispensable part of the LHC physics program. Its chief aim had been the
detailed characterization of the quark-gluon plasma (QGP) in lead-lead
collisions. Using additional data sets of proton-lead, proton-proton, and
xenon-xenon collisions, the program has also included many advances, for
example, in the understanding of the partonic nuclear structure, collectivity
in smaller collision systems, and electromagnetic interactions. This Letter of
Interest outlines the CMS Heavy Ion Group point of view regarding the
scientific case for the use of ultrarelativistic HI beams in the coming decade
to characterize QGP with unparalleled precision and to probe novel fundamental
physics phenomena. More specifically, it outlines the open questions in the
field which can be addressed with CMS, and aims to promote engagement from the
US community and its international partners by building upon the recently
concluded Snowmass 2022 exercise, the input provided to the European Strategy
for Particle Physics, and proposed continuations and extensions of the last
version of the US Long-Range Plan for Nuclear Physics.

Using relativistic Hartree-Fock approximation, we investigate the properties
of the neutron-star matter in detail. In the present calculation, we consider
not only the tensor coupling of vector mesons to octet baryons and the form
factors at interaction vertexes but also the internal (quark) structure change
of baryons in dense matter. The relativistic Hartree-Fock calculations are
performed in two ways: one is the calculation with the coupling constants
determined by SU(6) (quark model) symmetry, the other is with the coupling
constants based on SU(3) (flavor) symmetry. For the latter case, we use the
latest Nijmegen (ESC08) model. Then, it is very remarkable that the particle
composition of the core matter in SU(3) symmetry is completely different from
that in SU(6) symmetry. In SU(6) symmetry, all octet baryons appear in the
density region below $\sim 1.2$ fm$^{-3}$, while, in the ESC08 model, only the
\Xi^- hyperon is produced. Furthermore, the medium modification of the internal
baryon structure hardens the equation of state for the core matter. Taking all
these effects into account, we can obtain the maximum neutron-star mass which
is consistent with the recently observed mass, 1.97 \pm 0.04 M_\sun (PSR
J1614-2230). We therefore conclude that the extension from SU(6) symmetry to
SU(3) symmetry in the meson-baryon couplings and the internal baryon-structure
variation in matter certainly enhance the mass of neutron star. Furthermore,
the effects of the form factor at vertex and the Fock contribution including
the tensor coupling due to the vector mesons are indispensable to describe the
core matter. In particular, the Fock term is very vital in reproducing the
preferable value of symmetry energy, a_4 (\simeq 30 - 40 MeV), in nuclear
matter.

We calculate four classes of high energy massive string scattering amplitudes
of fermionic string theory at arbitrary mass levels in the Regge regime (RR).
We show that all four leading order amplitudes in the RR can be expressed in
terms of the Kummer function of the second kind. Based on the summation
algorithm of a set of extended signed Stirling number identities, we show that
all four ratios calculated previously by the method of decoupling of zero-norm
states among scattering amplitudes in the Gross Regime (GR) can be extracted
from this Kummer function in the RR. Finally, we conjecture and give evidences
that the existence of these four GR ratios in the RR persists to subleading
orders in the Regge expansion of all high energy fermionic string scattering
amplitudes.

Recently, Borisenko et al have posted a Comment (arXiv:1108.1159) where they
suggest an alternative interpretation of our de Haas-van Alphen (dHvA)
measurements on the superconductor LiFeAs. In our original paper
(arXiv:1107.4375) we concluded that our measurements of the bulk Fermi surface
were not consistent with the surface bands observed thus far by ARPES.
Borisenko et al dispute this and suggest the two measurements are consistent if
some of the orbits we observe are due to magnetic breakdown. We argue here that
this scenario is inconsistent with the experimental data and therefore that our
original conclusion stands.

While using drones for remote surveillance missions, it is mandatory to do
path planning of the vehicle since these are pilot-less vehicles. Path
planning, whether offline or online, entails setting up the path as a sequence
of locations in the 3D Euclidean space, whose coordinates happen to be
latitude, longitude and altitude. For the specific application of remote
surveillance of long linear infrastructures in non-urban terrain, the
continuous 3D-ESP problem practically entails two important scalar costs. The
first scalar cost is the distance traveled along the planned path. Since drones
are battery operated, hence it is needed that the path length between fixed
start and goal locations of a mission should be minimal at all costs. The other
scalar cost is the cost of transmitting the acquired video during the mission
of remote surveillance, via a camera mounted in the drone's belly. Because of
the length of surveillance target which is long linear infrastructure, the
amount of video generated is very high and cannot be generally stored in its
entirety, on board. If the connectivity is poor along certain segments of a
naive path, to boost video transmission rate, the transmission power of the
signal is kept high, which in turn dissipates more battery energy. Hence a path
is desired that simultaneously also betters what is known as communication
cost. These two costs trade-off, and hence Pareto optimization is needed for
this 3D bi-objective Euclidean shortest path problem. In this report, we study
the mono-objective offline path planning problem, based on the distance cost,
while posing the communication cost as an upper-bounded constraint. The
bi-objective path planning solution is sketched out towards the end.

Existing convolutional neural networks widely adopt spatial down-/up-sampling
for multi-scale modeling. However, spatial up-sampling operators (\emph{e.g.},
interpolation, transposed convolution, and un-pooling) heavily depend on local
pixel attention, incapably exploring the global dependency. In contrast, the
Fourier domain obeys the nature of global modeling according to the spectral
convolution theorem. Unlike the spatial domain that performs up-sampling with
the property of local similarity, up-sampling in the Fourier domain is more
challenging as it does not follow such a local property. In this study, we
propose a theoretically sound Deep Fourier Up-Sampling (FourierUp) to solve
these issues. We revisit the relationships between spatial and Fourier domains
and reveal the transform rules on the features of different resolutions in the
Fourier domain, which provide key insights for FourierUp's designs. FourierUp
as a generic operator consists of three key components: 2D discrete Fourier
transform, Fourier dimension increase rules, and 2D inverse Fourier transform,
which can be directly integrated with existing networks. Extensive experiments
across multiple computer vision tasks, including object detection, image
segmentation, image de-raining, image dehazing, and guided image
super-resolution, demonstrate the consistent performance gains obtained by
introducing our FourierUp.

When Can Neural Networks Learn Connected Decision Regions?

Previous work has questioned the conditions under which the decision regions
of a neural network are connected and further showed the implications of the
corresponding theory to the problem of adversarial manipulation of classifiers.
It has been proven that for a class of activation functions including leaky
ReLU, neural networks having a pyramidal structure, that is no layer has more
hidden units than the input dimension, produce necessarily connected decision
regions. In this paper, we advance this important result by further developing
the sufficient and necessary conditions under which the decision regions of a
neural network are connected. We then apply our framework to overcome the
limits of existing work and further study the capacity to learn connected
regions of neural networks for a much wider class of activation functions
including those widely used, namely ReLU, sigmoid, tanh, softlus, and
exponential linear function.

Privacy-Utility Tradeoff in a Guessing Framework Inspired by Index
Coding

This paper studies the tradeoff in privacy and utility in a single-trial
multi-terminal guessing (estimation) framework using a system model that is
inspired by index coding. There are $n$ independent discrete sources at a data
curator. There are $m$ legitimate users and one adversary, each with some side
information about the sources. The data curator broadcasts a distorted function
of sources to legitimate users, which is also overheard by the adversary. In
terms of utility, each legitimate user wishes to perfectly reconstruct some of
the unknown sources and attain a certain gain in the estimation correctness for
the remaining unknown sources. In terms of privacy, the data curator wishes to
minimize the maximal leakage: the worst-case guessing gain of the adversary in
estimating any target function of its unknown sources after receiving the
broadcast data. Given the system settings, we derive fundamental performance
lower bounds on the maximal leakage to the adversary, which are inspired by the
notion of confusion graph and performance bounds for the index coding problem.
We also detail a greedy privacy enhancing mechanism, which is inspired by the
agglomerative clustering algorithms in the information bottleneck and privacy
funnel problems.

We show how the early data runs of the LHC can provide valuable checks of the
different components of the formalism used to predict the cross sections of
central exclusive processes. The `soft' rapidity gap survival factor can be
studied in electroweak processes, such as W+gaps events, where the bare
amplitude is well known. The generalized gluon distribution, in the appropriate
kinematic region, can be probed by exclusive Upsilon production. The
perturbative QCD effects, especially the Sudakov-like factor, can be probed by
exclusive two- and three-jet production. We discuss the possible role of
enhanced absorptive corrections which would violate the soft-hard factorization
implied in the usual formalism, and suggest ways that the LHC may explore their
presence.

The attraction of the Moon on objects at the surface of the Earth gives rise
to a so-called tidal force which is of the order of 1/10,000,000 times the
gravitational force of the Earth. For instance, when the Moon is located
between the Earth and the Sun (new moon) the distance from a given terrestrial
location to the Moon is shorter at noon than at midnight. This reduces the
gravitational acceleration and therefore increases the period of a simple
pendulum by a small amount. Although the change is of the order of 100
nanoseconds it appears that it can be detected. We give some preliminary
results and discuss how the accuracy can be further improved. It is hoped that
the present paper will encourage new experiments in this direction.

Learned knowledge graph representations supporting robots contain a wealth of
domain knowledge that drives robot behavior. However, there does not exist an
inference reconciliation framework that expresses how a knowledge graph
representation affects a robot's sequential decision making. We use a
pedagogical approach to explain the inferences of a learned, black-box
knowledge graph representation, a knowledge graph embedding. Our interpretable
model, uses a decision tree classifier to locally approximate the predictions
of the black-box model, and provides natural language explanations
interpretable by non-experts. Results from our algorithmic evaluation affirm
our model design choices, and the results of our user studies with non-experts
support the need for the proposed inference reconciliation framework.
Critically, results from our simulated robot evaluation indicate that our
explanations enable non-experts to correct erratic robot behaviors due to
nonsensical beliefs within the black-box.

The stability of solutions to evolution equations with respect to small
stochastic perturbations is considered. The stability of a stochastic dynamical
system is characterized by the local stability index. The limit of this index
with respect to infinite time describes the asymptotic stability of a
stochastic dynamical system. Another limit of the stability index is given by
the vanishing intensity of stochastic perturbations. A dynamical system is
stochastically unstable when these two limits do not commute with each other.
Several examples illustrate the thesis that there always exist such stochastic
perturbations which render a given dynamical system stochastically unstable.
The stochastic instability of quasi-isolated systems is responsible for the
irreversibility of time arrow.

Posterior consistency for the spectral density of non-Gaussian
stationary time series

Various nonparametric approaches for Bayesian spectral density estimation of
stationary time series have been suggested in the literature, mostly based on
the Whittle likelihood approximation. A generalization of this approximation
has been proposed in Kirch et al. who prove posterior consistency for spectral
density estimation in combination with the Bernstein-Dirichlet process prior
for Gaussian time series. In this paper, we will extend the posterior
consistency result to non-Gaussian time series by employing a general
consistency theorem of Shalizi for dependent data and misspecified models. As a
special case, posterior consistency for the spectral density under the Whittle
likelihood as proposed by Choudhuri, Ghosal and Roy is also extended to
non-Gaussian time series. Small sample properties of this approach are
illustrated with several examples of non-Gaussian time series.

We present a new class of gradient-type optimization methods that extends
vanilla gradient descent, mirror descent, Riemannian gradient descent, and
natural gradient descent. Our approach involves constructing a surrogate for
the objective function in a systematic manner, based on a chosen cost function.
This surrogate is then minimized using an alternating minimization scheme.
Using optimal transport theory we establish convergence rates based on
generalized notions of smoothness and convexity. We provide local versions of
these two notions when the cost satisfies a condition known as nonnegative
cross-curvature. In particular our framework provides the first global rates
for natural gradient descent and the standard Newton's method.

DDColor: Towards Photo-Realistic and Semantic-Aware Image Colorization
via Dual Decoders
| null | null | null | null |
cs.CV
|
http://arxiv.org/licenses/nonexclusive-distrib/1.0/
|
Automatic image colorization is a challenging problem. Due to the high
illness and multi-modal uncertainty, directly training a deep neural network
usually leads to incorrect semantic colors and low color richness. Recent
transformer-based methods can deliver better results, but they often rely on
manually designed priors, which are hard to implement and suffer from poor
generalization ability. Moreover, they tend to introduce serious color bleeding
effects since color attention is performed on single-scale features, thus fail
to exploit sufficient semantic information. To address these issues, we propose
DDColor, a new end-to-end method with dual decoders for image colorization. Our
approach includes a multi-scale image decoder and a transformer-based color
decoder. The former restores the spatial resolution of the image, while the
latter establishes the correlation between color and semantic representations
via cross-attention. Rather than using additional priors, our two decoders work
together to leverage multi-scale image features to guide optimization of
adaptive color queries, significantly alleviating color bleeding effects. In
addition, a simple yet effective colorfulness loss is introduced to further
enhance the color richness of generated results. Our extensive experiments
demonstrate that DDColor achieves significantly superior performance to
existing state-of-the-art works both quantitatively and qualitatively. Codes
will be made publicly available at https://github.com/piddnad/DDColor.

The spatiotemporal dynamics of cardiac tissue is an active area of research
for biologists, physicists, and mathematicians. Of particular interest is the
study of period-doubling bifurcations and chaos due to their link with cardiac
arrhythmogenesis. In this paper we study the spatiotemporal dynamics of a
recently developed model for calcium-driven alternans in a one dimensional
cable of tissue. In particular, we observe in the cable coexistence of regions
with chaotic and multi-periodic dynamics over wide ranges of parameters. We
study these dynamics using global and local Lyapunov exponents and spatial
trajectory correlations. Interestingly, near nodes -- or phase reversals --
low-periodic dynamics prevail, while away from the nodes the dynamics tend to
be higher-periodic and eventually chaotic. Finally, we show that similar
coexisting multi-periodic and chaotic dynamics can also be observed in a
detailed ionic model.

Perfect Gabriel filters of right ideals and their corresponding right rings
of quotients have the desirable feature that every module of quotients is
determined solely by the right ring of quotients. On the other hand, symmetric
rings of quotients have a symmetry that mimics the commutative case. In this
paper, we study rings of quotients that combine these two desirable properties.
We define the symmetric versions of a right perfect ring of quotients and a
right perfect Gabriel filter -- the perfect symmetric ring of quotients and the
perfect symmetric Gabriel filter and study their properties. Then we prove that
the standard construction of the total right ring of quotients can be adapted
to the construction of the largest perfect symmetric ring of quotients -- the
total symmetric ring of quotients. We also demonstrate that Morita's
construction of the total right ring of quotients can be adapted to the
construction of the total symmetric ring of quotients.

We study a two-dimensional t-J model close to the Ising limit in which charge
inhomogeneity is stabilized by an on-site potential e_s, by using
diagonalization in a restricted Hilbert space and finite temperature Quantum
Monte Carlo. Both site and bond centered stripes are considered and their
similitudes and differences are analyzed. The amplitude of charge inhomogeneity
is studied as e_s -> 0. Moreover, we show that the anti-phase domain ordering
occurs at a much lower temperature than the formation of charge inhomogeneities
and charge localization. Hole-hole correlations indicate a metallic behavior of
the stripes with no signs of hole attraction. Kinetic energies and current
susceptibilities are computed and indications of charge localization are
discussed. The study of the doping dependence in the range 0.083 < x < 0.167
suggests that these features are characteristic of the whole underdoped region.

DASC: Robust Dense Descriptor for Multi-modal and Multi-spectral
Correspondence Estimation
| null | null | null | null |
cs.CV

http://arxiv.org/licenses/nonexclusive-distrib/1.0/
|
Establishing dense correspondences between multiple images is a fundamental
task in many applications. However, finding a reliable correspondence in
multi-modal or multi-spectral images still remains unsolved due to their
challenging photometric and geometric variations. In this paper, we propose a
novel dense descriptor, called dense adaptive self-correlation (DASC), to
estimate multi-modal and multi-spectral dense correspondences. Based on an
observation that self-similarity existing within images is robust to imaging
modality variations, we define the descriptor with a series of an adaptive
self-correlation similarity measure between patches sampled by a randomized
receptive field pooling, in which a sampling pattern is obtained using a
discriminative learning. The computational redundancy of dense descriptors is
dramatically reduced by applying fast edge-aware filtering. Furthermore, in
order to address geometric variations including scale and rotation, we propose
a geometry-invariant DASC (GI-DASC) descriptor that effectively leverages the
DASC through a superpixel-based representation. For a quantitative evaluation
of the GI-DASC, we build a novel multi-modal benchmark as varying photometric
and geometric conditions. Experimental results demonstrate the outstanding
performance of the DASC and GI-DASC in many cases of multi-modal and
multi-spectral dense correspondences.

In the ballistic regime we study both semiclassically and quantum
mechanically the electron's dynamics in two-dimensional electron gas (2DEG) in
the presence of an inhomogeneous magnetic field applied perpendicular to the
plane. The magnetic field is constant inside four separate circular regions
which are located at the four corners of a square of side length larger than
the diameter of the circles, while outside the circles the magnetic field is
zero. We carry out the stability analysis of the periodic orbits and for given
initial conditions numerically calculate the two-dimensional invariant torus
embedded in the four-dimensional phase space. Applying the Bohr--Sommerfeld and
the Einstein--Brillouin--Keller semiclassical quantization methods we obtain
the energy levels for different magnetic field strengths. We also perform exact
quantum calculations solving numerically the discretized version of the
Schr\"odinger equation. In our calculations, we consider only those bound
states that are localized to the neighborhood of the four magnetic disks. We
show that the semiclassical results are in good agreement with those found from
our quantum calculations. Moreover, the current distribution and the phase of
the different wave functions enable us to deduce the two quantum numbers $n_1$
and $n_2$ characterizing the energy levels in the semiclassical methods.
Finally, we present two examples in which the quantum state shows a similar
structure to the previous states, but these are special in the following sense.
One of them is a scar state localized to the neighborhood of the periodic orbit
while this orbit is already unstable. In the case of the other state, the
current density is circulating in two rings in opposite direction. Thus, it is
not consistent with the classical motion in the neighborhood of the periodic
orbit.

We obtain a relativistically covariant wave equation for neutrinos in dense
matter and electromagnetic field, which describes both flavor oscillations and
neutrino spin rotation. Using this equation we construct a quasi-classical
theory of these phenomena. We obtain the probabilities of arbitrary spin-flavor
transitions assuming the external conditions to be constant. We demonstrate
that the resonance behavior of the transition probabilities is possible only
when the neutrino flavor states cannot be described as superpositions of the
mass eigenstates. We discover that a resonance, which is similar to the
Mikheev-Smirnov-Wolfenstein resonance, takes place for neutrinos in magnetic
field due to the transition magnetic moments. This resonance gives an
opportunity to determine, whether neutrinos are Dirac or Majorana particles.

Predicting Discharge Medications at Admission Time Based on Deep
Learning

|
Predicting discharge medications right after a patient being admitted is an
important clinical decision, which provides physicians with guidance on what
type of medication regimen to plan for and what possible changes on initial
medication may occur during an inpatient stay. It also facilitates medication
reconciliation process with easy detection of medication discrepancy at
discharge time to improve patient safety. However, since the information
available upon admission is limited and patients' condition may evolve during
an inpatient stay, these predictions could be a difficult decision for
physicians to make. In this work, we investigate how to leverage deep learning
technologies to assist physicians in predicting discharge medications based on
information documented in the admission note. We build a convolutional neural
network which takes an admission note as input and predicts the medications
placed on the patient at discharge time. Our method is able to distill semantic
patterns from unstructured and noisy texts, and is capable of capturing the
pharmacological correlations among medications. We evaluate our method on 25K
patient visits and compare with 4 strong baselines. Our methods demonstrate a
20% increase in macro-averaged F1 score than the best baseline.

We present a detailed analysis, based on the Forward Flux Sampling (FFS)
simulation method, of the switching dynamics and stability of two models of
genetic toggle switches, consisting of two mutually-repressing genes encoding
transcription factors (TFs); in one model (the exclusive switch), they mutually
exclude each other's binding, while in the other model (general switch) the two
transcription factors can bind simultaneously to the shared operator region. We
assess the role of two pairs of reactions that influence the stability of these
switches: TF-TF homodimerisation and TF-DNA association/dissociation. We
factorise the flipping rate k into the product of the probability rho(q*) of
finding the system at the dividing surface (separatrix) between the two stable
states, and a kinetic prefactor R. In the case of the exclusive switch, the
rate of TF-operator binding affects both rho(q*) and R, while the rate of TF
dimerisation affects only R. In the case of the general switch both TF-operator
binding and TF dimerisation affect k, R and rho(q*). To elucidate this, we
analyse the transition state ensemble (TSE). For the exclusive switch, varying
the rate of TF-operator binding can drastically change the pathway of
switching, while changing the rate of dimerisation changes the switching rate
without altering the mechanism. The switching pathways of the general switch
are highly robust to changes in the rate constants of both TF-operator and
TF-TF binding, even though these rate constants do affect the flipping rate;
this feature is unique for non-equilibrium systems.

The Lugiato-Lefever equation is a cubic nonlinear Schr\"odinger equation,
including damping, detuning and driving, which arises as a model in nonlinear
optics. We study the existence of stationary waves which are found as solutions
of a four-dimensional reversible dynamical system in which the evolutionary
variable is the space variable. Relying upon tools from bifurcation theory and
normal forms theory, we discuss the codimension 1 bifurcations. We prove the
existence of various types of steady solutions, including spatially localized,
periodic, or quasi-periodic solutions.

The numerical simulation of quantum many-body dynamics is typically limited
by the linear growth of entanglement with time. Recently numerical studies have
shown, however, that for 1D Bethe-integrable models the simulation of local
operators in the Heisenberg picture can be efficient as the corresponding
operator-space entanglement grows only logarithmically. Using the spin-1/2 XX
chain as generic example of an integrabel model that can be mapped to free
particles, we here provide a simple explanation for this. We show furthermore
that the same reduction of complexity applies to operators that have a
high-temperature auto correlation function which decays slower than
exponential, i.e., with a power law. This is amongst others the case for models
where the Blombergen-De Gennes conjecture of high-temperature diffusive
dynamics holds. Thus efficient simulability may already be implied by a single
conservation law (like that of total magnetization), as we will illustrate
numerically for the spin-1 XXZ model.

We present a novel domain adaptation framework that uses morphologic
segmentation to translate images from arbitrary input domains (real and
synthetic) into a uniform output domain. Our framework is based on an
established image-to-image translation pipeline that allows us to first
transform the input image into a generalized representation that encodes
morphology and semantics - the edge-plus-segmentation map (EPS) - which is then
transformed into an output domain. Images transformed into the output domain
are photo-realistic and free of artifacts that are commonly present across
different real (e.g. lens flare, motion blur, etc.) and synthetic (e.g.
unrealistic textures, simplified geometry, etc.) data sets. Our goal is to
establish a preprocessing step that unifies data from multiple sources into a
common representation that facilitates training downstream tasks in computer
vision. This way, neural networks for existing tasks can be trained on a larger
variety of training data, while they are also less affected by overfitting to
specific data sets. We showcase the effectiveness of our approach by
qualitatively and quantitatively evaluating our method on four data sets of
simulated and real data of urban scenes. Additional results can be found on the
project website available at http://jonathank.de/research/eps/ .

As machine learning (ML) models gain traction in clinical applications,
understanding the impact of clinician and societal biases on ML models is
increasingly important. While biases can arise in the labels used for model
training, the many sources from which these biases arise are not yet
well-studied. In this paper, we highlight disparate censorship (i.e.,
differences in testing rates across patient groups) as a source of label bias
that clinical ML models may amplify, potentially causing harm. Many patient
risk-stratification models are trained using the results of clinician-ordered
diagnostic and laboratory tests of labels. Patients without test results are
often assigned a negative label, which assumes that untested patients do not
experience the outcome. Since orders are affected by clinical and resource
considerations, testing may not be uniform in patient populations, giving rise
to disparate censorship. Disparate censorship in patients of equivalent risk
leads to undertesting in certain groups, and in turn, more biased labels for
such groups. Using such biased labels in standard ML pipelines could contribute
to gaps in model performance across patient groups. Here, we theoretically and
empirically characterize conditions in which disparate censorship or
undertesting affect model performance across subgroups. Our findings call
attention to disparate censorship as a source of label bias in clinical ML
models.

The sensitivity of polarization observables in the reaction $NN \to NN \phi$

the threshold predictions. A measurement of the beam - target asymmetry and the
$\phi$ decay anisotropy can help to disentangle the role of various reaction

(Abridged) Dust particles evolve in size and lattice structure in
protoplanetary disks, due to coagulation, fragmentation and crystallization,
and are radially and vertically mixed in disks. This paper aims at determining
the mineralogical composition and size distribution of the dust grains in disks
around 58 T Tauri stars observed with Spitzer/IRS. We present a spectral
decomposition model that reproduces the IRS spectra over the full spectral
range. The model assumes two dust populations: a warm component responsible for
the 10\mu m emission arising from the disk inner regions and a colder component
responsible for the 20-30\mu m emission, arising from more distant regions. We
show evidence for a significant size distribution flattening compared to the
typical MRN distribution, providing an explanation for the usual boxy 10\mu m
feature profile generally observed. We reexamine the crystallinity paradox,
observationally identified by Olofsson et al. (2009), and we find a
simultaneous enrichment of the crystallinity in both the warm and cold regions,
while grain sizes in both components are uncorrelated. Our modeling results do
not show evidence for any correlations between the crystallinity and either the
star spectral type, or the X-ray luminosity (for a subset of the sample). The
size distribution flattening may suggests that grain coagulation is a slightly
more effective process than fragmentation in disk atmospheres, and that this
imbalance may last over most of the T Tauri phase. This result may also point
toward small grain depletion via strong stellar winds or radiation pressure in
the upper layers of disk. The non negligible cold crystallinity fractions
suggests efficient radial mixing processes in order to distribute crystalline
grains at large distances from the central object, along with possible nebular
shocks in outer regions of disks that can thermally anneal amorphous grains.

In this work, the problem of cross-tier interference in a two-tiered
(macro-cell and cognitive small-cells) network, under the complete spectrum
sharing paradigm, is studied. A new orthogonal precoder transmit scheme for the
small base stations, called multi-user Vandermonde-subspace frequency division
multiplexing (MU-VFDM), is proposed. MU-VFDM allows several cognitive small
base stations to coexist with legacy macro-cell receivers, by nulling the
small- to macro-cell cross-tier interference, without any cooperation between
the two tiers. This cleverly designed cascaded precoder structure, not only
cancels the cross-tier interference, but avoids the co-tier interference for
the small-cell network. The achievable sum-rate of the small-cell network,
satisfying the interference cancelation requirements, is evaluated for perfect
and imperfect channel state information at the transmitter. Simulation results
for the cascaded MU-VFDM precoder show a comparable performance to that of
state-of-the-art dirty paper coding technique, for the case of a dense cellular
layout. Finally, a comparison between MU-VFDM and a standard complete spectrum
separation strategy is proposed. Promising gains in terms of achievable
sum-rate are shown for the two-tiered network w.r.t. the traditional bandwidth
management approach.

In quantum theory, it is widely accepted that all experimental results must
agree with theoretical predictions based on the Copenhagen interpretation.
However the classical system in the Copenhagen interpretation has not been
defined yet. On the other hand, although ongoing research of decoherence is
trying to elucidate the emergence of the classical world, it cannot answer why
we observe one of eigenstates in observed system. These situations show that
the relation between what we observe and physical law has not been elucidated.
Here I elucidate the relation by developing Everett's suggestion. Further, from
this point of view, I point out that today's brain science falls into circular
argument because it is trying to assign what we observe in the brain to process
of the subjective perception, and I suggest the future research line in brain
science.

We construct a planar diffusion process whose infinitesimal generator depends
only on the order of the components of the process. Speaking informally and a
bit imprecisely for the moment, imagine you run two Brownian-like particles on
the real line. At any given time, you assign positive drift g and diffusion
{\sigma} to the laggard; and you assign negative drift -h and diffusion {\rho}
to the leader.
We compute the transition probabilities of this process, discuss its
realization in terms of appropriate systems of stochastic differential
equations, study its dynamics under a time reversal, and note that these
involve singularly continuous components governed by local time. Crucial in our
analysis are properties of Brownian and semimartingale local time; properties
of the generalized perturbed Tanaka equation which we study here in detail; and
those of a one-dimensional diffusion with bang-bang drift.
We also show that our planar diffusion can be represented in terms of a
process with bang-bang drift, its local time at the origin, and an independent
standard Brownian motion, in a form which can be construed as a two-dimensional
analogue of the stochastic equation satisfied by the so-called skew Brownian
motion.

We analyze a tractable model of a limit order book on short time scales,
where the dynamics are driven by stochastic fluctuations between supply and
demand. We establish the existence of a limiting distribution for the highest
bid, and for the lowest ask, where the limiting distributions are confined
between two thresholds. We make extensive use of fluid limits in order to
establish recurrence properties of the model. We use the model to analyze
various high-frequency trading strategies, and comment on the Nash equilibria
that emerge between high-frequency traders when a market in continuous time is
replaced by frequent batch auctions.

Series elastic actuators (SEA) are playing an increasingly important role in
the fields of physical human-robot interaction. This paper focuses on the
modeling and control of a cable-driven SEA. First, the scheme of the
cable-driven SEA has been proposed, and a velocity controlled DC motor has been
used as its power source. Based on this, the model of the cable-driven SEA has
been built up. Further, a two degrees of freedom (2-DOF) control approach has
been employed to control the output torque. Simulation results have shown that
the 2-DOF method has achieved better robust performance than the PD method.

A Decision Procedure for a Theory of Finite Sets with Finite Integer

In this paper we extend a decision procedure for the Boolean algebra of
finite sets with cardinality constraints ($\mathcal{L}_{\lvert\cdot\rvert}$) to
a decision procedure for $\mathcal{L}_{\lvert\cdot\rvert}$ extended with set
terms denoting finite integer intervals ($\mathcal{L}_{[\,]}$). In
$\mathcal{L}_{[\,]}$ interval limits can be integer linear terms including
\emph{unbounded variables}. These intervals are a useful extension because they
allow to express non-trivial set operators such as the minimum and maximum of a
set, still in a quantifier-free logic. Hence, by providing a decision procedure
for $\mathcal{L}_{[\,]}$ it is possible to automatically reason about a new
class of quantifier-free formulas. The decision procedure is implemented as
part of the $\{log\}$ tool. The paper includes a case study based on the
elevator algorithm showing that $\{log\}$ can automatically discharge all its
invariance lemmas some of which involve intervals.

Constraint-based Task Specification and Trajectory Optimization for

To economically deploy robotic manipulators the programming and execution of
robot motions must be swift. To this end, we propose a novel, constraint-based
method to intuitively specify sequential manipulation tasks and to compute
time-optimal robot motions for such a task specification. Our approach follows
the ideas of constraint-based task specification by aiming for a minimal and
object-centric task description that is largely independent of the underlying
robot kinematics. We transform this task description into a non-linear
optimization problem. By solving this problem we obtain a (locally)
time-optimal robot motion, not just for a single motion, but for an entire
manipulation sequence. We demonstrate the capabilities of our approach in a
series of experiments involving five distinct robot models, including a highly
redundant mobile manipulator.

Chiral symmetry restoration and properties of Goldstone bosons at finite

We study chiral symmetry restoration by analyzing thermal properties of QCD's
(pseudo-)Goldstone bosons, especially the pion. The meson properties are
obtained from the spectral densities of mesonic imaginary-time correlation
functions. To obtain the correlation functions, we solve the Dyson-Schwinger
equations and the inhomogeneous Bethe-Salpeter equations in the leading
symmetry-preserving rainbow-ladder approximation. In the chiral limit, the pion
and its partner sigma degenerate at the critical temperature $T_c$. At $T
\gtrsim T_c$, it is found that the pion rapidly dissociates, which signals
deconfinement phase transition. Beyond the chiral limit, the pion dissociation
temperature can be used to define the pseudo-critical temperature of chiral
phase crossover, which is consistent with that obtained by the maximum point of
the chiral susceptibility. The parallel analysis for kaon and pseudoscalar
$s\bar{s}$ suggests that heavy mesons may survive above $T_c$.

We prove that any finite polyhedral manifold in 3D can be continuously
flattened into 2D while preserving intrinsic distances and avoiding crossings,
answering a 19-year-old open problem, if we extend standard folding models to
allow for countably infinite creases. The most general cases previously known
to be continuously flattenable were convex polyhedra and semi-orthogonal
polyhedra. For non-orientable manifolds, even the existence of an instantaneous
flattening (flat folded state) is a new result. Our solution extends a method
for flattening semi-orthogonal polyhedra: slice the polyhedron along parallel
planes and flatten the polyhedral strips between consecutive planes. We adapt
this approach to arbitrary nonconvex polyhedra by generalizing strip flattening
to nonorthogonal corners and slicing along a countably infinite number of
parallel planes, with slices densely approaching every vertex of the manifold.
We also show that the area of the polyhedron that needs to support moving
creases (which are necessary for closed polyhedra by the Bellows Theorem) can
be made arbitrarily small.

Modes of wall induced granular crystallisation in vibrational packing
| null | null | null | null |

http://arxiv.org/licenses/nonexclusive-distrib/1.0/
|
Granular crystallisation is an important phenomenon whereby ordered packing
structures form in granular matter under vibration. However, compared with the
well-developed principles of crystallisation at the atomic scale,
crystallisation in granular matter remains relatively poorly understood. To
investigate this behaviour further and bridge the fields of granular matter and
materials science, we simulated mono-disperse spheres confined in cylindrical
containers to study their structural dynamics during vibration. By applying
adequate vibration, disorder-to-order transitions were induced. Such
transitions were characterised at the particle scale through bond orientation
order parameters. As a result, emergent crystallisation was indicated by the
enhancement of the local order of individual particles and the number of
ordered particles. The observed heterogeneous crystallisation was characterised
by the evolution of the spatial distributions via coarse-graining the order
index. Crystalline regimes epitaxially grew from templates formed near the
container walls during vibration, here termed the wall effect. By varying the
geometrical dimensions of cylindrical containers, the obtained crystallised
structures were found to differ at the cylindrical wall zone and the planar
bottom wall zone. The formed packing structures were quantitatively compared to
X-ray tomography results using again these order parameters. The findings here
provide a microscopic perspective for developing laws governing structural
dynamics in granular matter.

We derive a formalism, the separation method, for the efficient and accurate
calculation of two-body matrix elements for a Gaussian potential in the
cylindrical harmonic-oscillator basis. This formalism is of critical importance
for Hartree-Fock and Hartree-Fock-Bogoliubov calculations in deformed nuclei
using realistic, finite-range effective interactions between nucleons. The
results given here are also relevant for microscopic many-body calculations in
atomic and molecular physics, as the formalism can be applied to other types of
interactions beyond the Gaussian form. The derivation is presented in great
detail to emphasize the methodology, which relies on generating functions. The
resulting analytical expressions for the Gaussian matrix elements are checked
for speed and accuracy as a function of the number of oscillator shells and
against direct numerical integration.

Wireless tags are increasingly used to track and identify common items of
interest such as retail goods, food, medicine, clothing, books, documents,
keys, equipment, and more. At the same time, there is a need for labelled
visual data featuring such items for the purpose of training object detection
and recognition models for robots operating in homes, warehouses, stores,
libraries, pharmacies, and so on. In this paper, we ask: can we leverage the
tracking and identification capabilities of such tags as a basis for a
large-scale automatic image annotation system for robotic perception tasks? We
present RF-Annotate, a pipeline for autonomous pixel-wise image annotation
which enables robots to collect labelled visual data of objects of interest as
they encounter them within their environment. Our pipeline uses unmodified
commodity RFID readers and RGB-D cameras, and exploits arbitrary small-scale
motions afforded by mobile robotic platforms to spatially map RFIDs to
corresponding objects in the scene. Our only assumption is that the objects of
interest within the environment are pre-tagged with inexpensive battery-free
RFIDs costing 3-15 cents each. We demonstrate the efficacy of our pipeline on
several RGB-D sequences of tabletop scenes featuring common objects in a
variety of indoor environments.

Recent work by Prodan and the second author showed that weak invariants of
topological insulators can be described using Kasparov's $KK$-theory. In this
note, a complementary description using semifinite index theory is given. This
provides an alternative proof of the index formulae for weak complex
topological phases using the semifinite local index formula. Real invariants
and the bulk-boundary correspondence are also briefly considered.

We discuss what information can be safely extracted from background
independent off-shell string theory. The major obstacle in doing so is that
renormalization conditions of the underlying world-sheet theories are not
exactly known. To get some insight, we first consider the tachyon and gauge
field backgrounds and carry out computations in different renormalization
schemes for both, bosonic string and superstring. Next, we use a principle of
universality (renormalization scheme independence) to somehow compensate the
missing of the renormalization conditions and get information we are looking
for. It turns out that some asymptotics which are responsible for the
potentials only obey the principle of universality.

We discuss the average length l of the shortest non-contractible loop on
surfaces in the two-dimensional pure quantum gravity ensemble. The value of
$\gamma_{str}$ and the explicit form of the loop functions indicate that l
diverges at the critical point. Scaling arguments suggest that the critical
exponent of l is 1/2. We show that this value of the critical exponent is also
obtained for branched polymers where the calculation is straightforward.

It is well known that standard one-dimensional Brownian motion B(t) has no
isolated zeros almost surely. We show that for any alpha<1/2 there are
alpha-H\"older continuous functions f for which the process B-f has isolated
zeros with positive probability. We also prove that for any continuous function
f, the zero set of B-f has Hausdorff dimension at least 1/2 with positive
probability, and 1/2 is an upper bound if f is 1/2-H\"older continuous or of
bounded variation.

the weight lattice of $SU(3)$. We first, develop the twisted 3D $N=4$ SYM in
continuum by using superspace method where the scalar supercharge $Q$ is
manifestly exhibited. Then, we show how to engineer the 3D lattice
$\mathcal{L}_{3D}^{su_3\times u_1}$ that host this theory. After that we build
the lattice action $\mathcal{S}_{latt}$ invariant under the 3 following: (i)
$U(N)$ gauge invariance, (ii) BRST symmetry, (iii) the hidden $SU(3) \times
U(1)$ symmetry of $\mathcal{L}_{3D}^{su_3\times u_1}$. Other features such as
reduction to twisted 2D supersymmetry with 8 supercharges living on

the relation with known results are also given.

Dimension Reduction Using Rule Ensemble Machine Learning Methods: A
Numerical Study of Three Ensemble Methods
| null | null | null | null |
stat.ML stat.CO

http://creativecommons.org/licenses/publicdomain/
|
Ensemble methods for supervised machine learning have become popular due to
their ability to accurately predict class labels with groups of simple,
lightweight "base learners." While ensembles offer computationally efficient
models that have good predictive capability they tend to be large and offer
little insight into the patterns or structure in a dataset. We consider an
ensemble technique that returns a model of ranked rules. The model accurately
predicts class labels and has the advantage of indicating which parameter
constraints are most useful for predicting those labels. An example of the rule
ensemble method successfully ranking rules and selecting attributes is given
with a dataset containing images of potential supernovas where the number of
necessary features is reduced from 39 to 21. We also compare the rule ensemble
method on a set of multi-class problems with boosting and bagging, which are
two well known ensemble techniques that use decision trees as base learners,
but do not have a rule ranking scheme.

For non-equilibrium systems of interacting particles and for interacting
diffusions in d dimensions, a novel fluctuation relation is derived. The
theorem establishes a quantitative relation between the probabilities of
observing two current values in different spatial directions. The result is a
consequence of spatial symmetries of the microscopic dynamics, generalizing in
this way the Gallavotti-Cohen fluctuation theorem related to the time-reversal
symmetry. This new perspective opens up the possibility of direct experimental
measurements of fluctuation relations of vectorial observables.

Autonomous driving technology pledges safety, convenience, and energy
efficiency. Challenges include the unknown intentions of other road users:
communication between vehicles and with the road infrastructure is a possible
approach to enhance awareness and enable cooperation. Connected and automated
vehicles (CAVs) have the potential to disrupt mobility, extending what is
possible with driving automation and connectivity alone. Applications include
real-time control and planning with increased awareness, routing with
micro-scale traffic information, coordinated platooning using traffic signals
information, eco-mobility on demand with guaranteed parking. This paper
introduces a control and planning architecture for CAVs, and surveys the state
of the art on each functional block therein; the main focus is on techniques to
improve energy efficiency. We provide an overview of existing algorithms and
their mutual interactions, we present promising optimization-based approaches
to CAVs control and identify future challenges.

We investigate the bulk topological proximity effect in multilayer hexagonal
lattice systems by which one can introduce topological properties into a system
composed of multiple trivial layers by tunnel coupling to a single nontrivial
layer described by the Haldane model. This phenomenon depends not only on the
number of layers but also on their arrangement, which can lead to the emergence
of dark states in multilayer systems. The response of a trivial system to the
proximity of a topological insulator appears to be highly nonlocal, in contrast
to the proximity effect observed in context of superconductivity. Furthermore,
for a wide range of parameters our system is semimetallic with multiple Dirac
points emerging in the Brillouin zone.

This is a continuation of our previous paper 1502.01744. We examine a class
of non-commutative algebras A that depend on an elliptic curve and a
translation automorphism of it. They may be defined in terms of the
4-dimensional Sklyanin algebra S that is associated to the same data. The
algebra A has the same Hilbert series as the polynomial ring in 4 variables,
and there is an associated non-commutative variety, Proj(A), that is a
non-commutative analogue of P^3. The structure and representation theory of A,
and the geometric properties of Proj(A) are closely related to the geometric
properties of E sitting as a quartic curve in P^3. Our main results concern the
classification of point modules, fat point modules, line modules, and the
incidence relations between them. The line modules are parametrized by a degree
20 curve in the Grassmannian G(1,3) that is a union of 4 disjoint plane conics
and 3 disjoint quartic elliptic curves that are isomorphic to E/(t) where t
runs over the three 2-torsion points. A finite quantum group related to the
Heisenberg group of size 4^3 acts as auto-equivalences of the category of
graded A-modules and those quantum symmetries of A play a central role in our
analysis.

We construct a series of homomorphisms from the $Y$-filtration on the monoid
of homology cylinders to torsion modules via the mod $\mathbb{Z}$ reduction of
the LMO functor. The restriction of our homomorphism to the lower central
series of the Torelli group does not factor through Morita's refinement of the
Johnson homomorphism. We use it to show that the abelianization of the Johnson
kernel of a closed surface has torsion elements. We also determine the third
graded quotient $Y_3\mathcal{IC}_{g,1}/Y_4$ of the $Y$-filtration.

We calculate the two-pion correlation function for an expanding hadron source
with a finite baryon density. The space-time evolution of the source is
described by relativistic hydrodynamics and the Hanbury-Brown-Twiss (HBT)
radius is extracted after effects of collective expansion and multiple
scattering on the HBT interferometry have been taken into account, using
quantum probability amplitudes in a path-integral formalism. We find that this
radius is substantially smaller than the HBT radius extracted from the
freeze-out configuration.

A novel general formalism for the maximal symetrization and reduction of
fields (MSRF) is proposed and applied to wavefunctions in solid state
nanostructures. Its primary target is to provide an essential tool for the
study and analysis of the electronic and optical properties of semiconductor
quantum heterostructures with relatively high point-group symmetry, and studied
with the $k\cdot p$ formalism. Nevertheless the approach is valid in a much
larger framework than $k\cdot p$ theory, it is applicable to arbitrary systems
of coupled partial differential equations (e.g. strain equations or Maxwell
equations). For spinless problems (scalar equations), one can use a systematic
Spatial Domain Reduction (SDR) technique which allows, for every irreducible
representation, to reduce the set of equations on a minimal domain with
automatic incorporation of the boundary conditions at the border, which are
shown to be non-trivial in general. For a vectorial or spinorial set of
functions, the SDR technique must be completed by the use of an optimal basis
in vectorial or spinorial space (in a crystal we call it the Optimal Bloch
function Basis - OBB). The advantages are numerous: sharper insights on the
symmetry properties of every eigenstate, minimal coupling schemes, analytically
and computationally exploitable at the component function level, minimal
computing domains. The formalism can be applied also as a postprocessing
operation, offering all subsequent analytical and computationnal advantages of
symmetrization. The specific case of a quantum wire (QWRs) with $C_{3v}$ point
group symmetry is used as a concrete illustration of the application of MSRF.

b) the oxygen to hydrogen abundance ratio, O/H; c) the carbon to oxygen
abundance ratio, C/O; d) the helium to oxygen and helium to heavy elements

A remarkable feature of Schur functions -- the common eigenfunctions of
cut-and-join operators from $W_\infty$ -- is that they factorize at the
peculiar two-parametric topological locus in the space of time-variables, what
is known as the hook formula for quantum dimensions of representations of
$U_q(SL_N)$ and plays a big role in various applications. This factorization
survives at the level of Macdonald polynomials. We look for its further
generalization to {\it generalized} Macdonald polynomials (GMP), associated in
the same way with the toroidal Ding-Iohara-Miki algebras, which play the
central role in modern studies in Seiberg-Witten-Nekrasov theory. In the
simplest case of the first-coproduct eigenfunctions, where GMP depend on just
two sets of time-variables, we discover a weak factorization -- on a
codimension-one slice of the topological locus, what is already a very
non-trivial property, calling for proof and better understanding.

The Mertens' first theorem gives us the following asymptotic formula
\begin{equation*} \sum_{\substack{p\leq x\\ p~prime}}\frac{lnp}{p}=lnx+O(1),
\end{equation*} and the Mertens' second theorem indicates that there exists a
constant $B\approx 0.261$, named the Mertens constant, such that
\begin{equation*} \sum_{\substack{p\leq x\\
p~prime}}\frac{1}{p}=ln(lnx)+B+O\left(\frac{1}{lnx}\right). \end{equation*} In
this paper, by using the Abel summation formula and Dirichlet's hyperbola
method, we extend them to multiple cases.

Here we clarify the assumptions made and conclusions reached in our paper
"The thermodynamical cost of some interpretations of quantum theory" [Phys.
Rev. A 94, 052127 (2016)], at the light of the criticisms of Prunkl and Timpson
[Stud. Hist. Philos. Sci. Part B 63, 114 (2018)], and Davidsson (Master thesis,
Stockholm University, 2018). We point out some misunderstandings and some
weaknesses of the counterexample Prunkl and Timpson present to challenge our
conclusion. We thus conclude, once more, that interpretations of quantum theory
which consider the probabilities of measurement outcomes to be determined by
objective properties of the measured system and satisfy the assumption that the
measured system only has finite memory have a thermodynamical cost.

Bioactive glasses release ions such as sodium when implanted in the human
body. However, an excess of the released ions can cause problems related to
cytotoxicity. The ion release control is considered one of the primary
challenges in developing new bioactive glasses. Here, we use molecular dynamics
simulations to investigate the effect of the density on atoms' dynamics in an
archetypal phosphosilicate bioactive system. The diffusion coefficient displays
three main regimes with increasing density. The mobility of the modifiers is
significantly affected by the increase of the density, especially Na, compared
to other elements. We use a modified Arrhenian model to access the complex
dynamic behavior of 45S5 melts and correlate it to the structural changes by
evaluating the network connectivity and pair-excess entropy. Overall, our
results present a step toward the rational design of bioactive glasses and a
key to controlling the ion release of bioactive glasses.

We study Diophantine equations of type $f(x)=g(y)$, where $f$ and $g$ are
lacunary polynomials. According to a well known finiteness criterion, for a
number field $K$ and nonconstant $f, g\in K[x]$, the equation $f(x)=g(y)$ has
infinitely many solutions in $S$-integers $x, y$ only if $f$ and $g$ are
representable as a functional composition of lower degree polynomials in a
certain prescribed way. The behaviour of lacunary polynomials with respect to
functional composition is a topic of independent interest, and has been studied
by several authors. In this paper we utilize known results and develop some new
results on the latter topic.

We consider a generalization of the Kuramoto model of coupled oscillators to
the situation where communities of oscillators having essentially different
natural frequencies interact. General equations describing possible resonances
between the communities' frequencies are derived. The mostly simple situation
of three resonantly interacting groups is analyzed in details. We find
conditions for the mutual coupling to promote or suppress synchrony in
individual populations, and present examples where interaction between
communities leads to their synchrony, or to a partially asynchronous state, or
to a chaotic dynamics of order parameters.

It is well known that a real analytic symplectic diffeomorphism of the
$2d$-dimensional disk ($d\geq 1$) admitting the origin as a non-resonant
elliptic fixed can be {\it formally} conjugated to its Birkhoff Normal Form, a
formal power series defining a {\it formal integrable} symplectic
diffeomorphism at the origin. We prove in this paper that this Birkhoff Normal
Form is in general divergent. This solves, in any dimension, the question of
determining which of the two alternatives of Perez-Marco's theorem \cite{PM} is
true and answers a question by H. Eliasson. Our result is a consequence of the
fact that when $d=1$ the convergence of the formal object that is the BNF has
strong dynamical consequences on the Lebesgue measure of the set of invariant
circles in arbitrarily small neighborhoods of the origin. Our proof, as well as
our results, extend to the case of real-analytic diffeomorphisms of the annulus
admitting a Diophantine invariant torus.

15 intermediate-band filters of the Beijing-Arizona-Taiwan-Connecticut (BATC)
photometric system. The GCs and GC candidates were selected from the Revised
Bologna Catalog (v.3.5). We obtain the cluster ages by comparing the
photometric data with up-to-date theoretical synthesis models. The photometric
data used are {\sl GALEX} far- and near-ultraviolet and 2MASS near-infrared
$JHK_{\rm s}$ magnitudes, combined with optical photometry. The ages of our
sample clusters cover a large range, although most clusters are younger than 10
Gyr. Combined with the ages obtained in our series of previous papers focusing
on the M31 GC system, we present the full M31 GC age distribution. The M31 GC
system contains populations of young and intermediate-age GCs, as well as the
`usual' complement of well-known old GCs, i.e., GCs of similar age as the
majority of the Galactic GCs. In addition, young GCs (and GC candidates) are
distributed nearly uniformly in radial distance from the center of M31, while
most old GCs (and GC candidates) are more strongly concentrated.

User preference learning is generally a hard problem. Individual preferences
are typically unknown even to users themselves, while the space of choices is
infinite. Here we study user preference learning from information-theoretic
perspective. We model preference learning as a system with two interacting
sub-systems, one representing a user with his/her preferences and another one
representing an agent that has to learn these preferences. The user with
his/her behaviour is modeled by a parametric preference function. To
efficiently learn the preferences and reduce search space quickly, we propose
the agent that interacts with the user to collect the most informative data for
learning. The agent presents two proposals to the user for evaluation, and the
user rates them based on his/her preference function. We show that the optimum
agent strategy for data collection and preference learning is a result of
maximin optimization of the normalized weighted Kullback-Leibler (KL)
divergence between true and agent-assigned predictive user response
distributions. The resulting value of KL-divergence, which we also call
remaining system uncertainty (RSU), provides an efficient performance metric in
the absence of the ground truth. This metric characterises how well the agent
can predict user and, thus, the quality of the underlying learned user
(preference) model. Our proposed agent comprises sequential mechanisms for user
model inference and proposal generation. To infer the user model (preference
function), Bayesian approximate inference is used in the agent. The data
collection strategy is to generate proposals, responses to which help resolving
uncertainty associated with prediction of the user responses the most. The
efficiency of our approach is validated by numerical simulations.

Enabling Multi-Shell b-Value Generalizability of Data-Driven Diffusion
Models with Deep SHORE

Intra-voxel models of the diffusion signal are essential for interpreting
organization of the tissue environment at micrometer level with data at
millimeter resolution. Recent advances in data driven methods have enabled
direct compari-son and optimization of methods for in-vivo data with externally
validated histological sections with both 2-D and 3-D histology. Yet, all
existing methods make limiting assumptions of either (1) model-based linkages
between b-values or (2) limited associations with single shell data. We
generalize prior deep learning models that used single shell spherical harmonic
transforms to integrate the re-cently developed simple harmonic oscillator
reconstruction (SHORE) basis. To enable learning on the SHORE manifold, we
present an alternative formulation of the fiber orientation distribution (FOD)
object using the SHORE basis while rep-resenting the observed diffusion
weighted data in the SHORE basis. To ensure consistency of hyper-parameter
optimization for SHORE, we present our Deep SHORE approach to learn on a
data-optimized manifold. Deep SHORE is evalu-ated with eight-fold
cross-validation of a preclinical MRI-histology data with four b-values.
Generalizability of in-vivo human data is evaluated on two separate 3T MRI
scanners. Specificity in terms of angular correlation (ACC) with the
preclinical data improved on single shell: 0.78 relative to 0.73 and 0.73,
multi-shell: 0.80 relative to 0.74 (p < 0.001). In the in-vivo human data, Deep
SHORE was more consistent across scanners with 0.63 relative to other
multi-shell methods 0.39, 0.52 and 0.57 in terms of ACC. In conclusion, Deep
SHORE is a promising method to enable data driven learning with DW-MRI under
conditions with varying b-values, number of diffusion shells, and gradient
directions per shell.

Knowing the high-energy radiation environment of a star over a planet's
formation and evolutionary period is critical in determining if that planet is
potentially habitable and if any biosignatures could be detected, as UV
radiation can severely change or destroy a planet's atmosphere. Current efforts
for finding a potentially habitable planet are focused on M stars, yet K stars
may offer more habitable conditions due to decreased stellar activity and more
distant and wider habitable zones (HZ). While M star activity evolution has
been observed photometrically and spectroscopically, there has been no
dedicated investigation of K-star UV evolution. We present the first
comprehensive study of the near-UV, far-UV, and X-ray evolution of K stars. We
used members of young moving groups and clusters ranging in age from 10 - 625
Myr combined with field stars and their archived GALEX UV and ROSAT X-ray data
to determine how the UV and X-ray radiation evolve. We find that the UV and
X-ray flux incident on a HZ planet is 5 - 50 times lower than that of HZ
planets around early-M stars and 50 - 1000 times lower than those around late-M
stars, due to both an intrinsic decrease in K dwarf stellar activity occurring
earlier than for M dwarfs and the more distant location of the K dwarf HZ.

We report low resolution near infrared spectroscopic observations of the
eruptive star FU Orionis using the Integral Field Spectrograph Project 1640
installed at the Palomar Hale telescope. This work focuses on elucidating the
nature of the faint source, located 0.5" south of FU Ori, and identified in
2003 as FU Ori S. We first use our observations in conjunction with published
data to demonstrate that the two stars are indeed physically associated and
form a true binary pair. We then proceed to extract J and H band
spectro-photometry using the damped LOCI algorithm, a reduction method tailored
for high contrast science with IFS. This is the first communication reporting
the high accuracy of this technique, pioneered by the Project 1640 team, on a
faint astronomical source. We use our low resolution near infrared spectrum in
conjunction with 10.2 micron interferometric data to constrain the infrared
excess of FU Ori S. We then focus on estimating the bulk physical properties of
FU Ori S. Our models lead to estimates of an object heavily reddened, A_V
=8-12, with an effective temperature of ~ 4000-6500 K . Finally we put these
results in the context of the FU Ori N-S system and argue that our analysis
provides evidence that FU Ori S might be the more massive component of this
binary system

The understanding of stellar structure represents the crossroads of our
theories of the nuclear force and the gravitational interaction under the most
extreme conditions observably accessible. It provides a powerful probe of the
strong field regime of General Relativity, and opens fruitful avenues for the
exploration of new gravitational physics. The latter can be captured via
modified theories of gravity, which modify the Einstein-Hilbert action of
General Relativity and/or some of its principles. These theories typically
change the stellar structure equations, thus having a large impact on the
astrophysical properties of the corresponding stars and opening a new window to
constrain these theories with present and future observations. For relativistic
(neutron) stars, the uncertainty on the equation of state of matter at
supranuclear densities intertwines with the new parameters of the modified
gravity side, providing new phenomenology for the predictions of stellar
structure models, such as mass-radius relations, maximum masses, or moment of
inertia. For non-relativistic stars (white, brown and red dwarfs), the
weakening/strengthening of the gravitational force inside astrophysical bodies
may induce changes on the star's mass, radius or luminosity, having an impact,
for instance, in the Chandrasekhar's limit for white dwarfs, or in the minimum
mass for stable hydrogen burning in brown dwarfs. This work aims to provide a
broad overview of the main such results achieved in the recent literature, by
combining the results and constraints obtained from the analysis of
relativistic and non-relativistic stars in different scenarios. Moreover, we
will build a bridge between the efforts of the community working on different
theories, formulations, types of stars, theoretical modellings, and
observational aspects, highlighting some of the most promising opportunities in
the field.

Massive constituent quarks and unified description of freeze-out

The possibility of unified description of hadron multiple production in heavy
ion collisions over the wide energy interval, from few hundreds MeV/n at
GSI/SIS through 11 GeV/n at BNL/AGS up to 160 GeV/n at CERN/SPS, has been
emphasized recently by J. Cleymans and K. Redlich. They, and somewhat later B.
Muller and J. Rafelski, treated this fact as an indication that quark-gluon
plasma (QGP) can be produced even at very low energies of impinging nuclei. In
our opinion, it rather witnesses that a massive constituent quark (valon) - not
massless current quark and gluon! - is just what becomes "quite easily" to be
unbound, and thus supports the expectation that in course of compression and
heating from hadronic state to QGP (or, vice versa, of expansion and cooling
down from QGP to hadronic state) nuclear matter should pass through an
intermediate phase in between.

Quantum--mechanical operators corresponding to canonical momentum and
position of a point--like particle, which follow from the quantum field theory
in the general Riemannian space-time, satisfy generally to a deformation of the
canonical commutation relations with $c^{-2}$ as the parameter of deformation.
For operators of the quasi-Cartesian coordinates in the closed and open
Friedman--Robertson--Walker models, the deformation reproduces the spatial part
of the well--known Snyder formula for quantization of the Minkowsky space-time.
The spatially-flat models are distinguished apart by that the deformation is
reduced exactly to the standard canonical commutation relations, which
correlates remarkably with the fact of the observed flatness of the Universe.
Conditions are briefly discussed for which the deformation could have
cosmological manifestations. Key words: quantum mechanics, cosmology, quantized
space.

Deep neural networks have demonstrated their superior performance in almost
every Natural Language Processing task, however, their increasing complexity
raises concerns. In particular, these networks require high expenses on
computational hardware, and training budget is a concern for many. Even for a
trained network, the inference phase can be too demanding for
resource-constrained devices, thus limiting its applicability. The
state-of-the-art transformer models are a vivid example. Simplifying the
computations performed by a network is one way of relaxing the complexity
requirements. In this paper, we propose an end to end binarized neural network
architecture for the intent classification task. In order to fully utilize the
potential of end to end binarization, both input representations (vector
embeddings of tokens statistics) and the classifier are binarized. We
demonstrate the efficiency of such architecture on the intent classification of
short texts over three datasets and for text classification with a larger
dataset. The proposed architecture achieves comparable to the state-of-the-art
results on standard intent classification datasets while utilizing ~ 20-40%
lesser memory and training time. Furthermore, the individual components of the
architecture, such as binarized vector embeddings of documents or binarized
classifiers, can be used separately with not necessarily fully binary
architectures.

Fast Calculation of Credit Exposures for Barrier and Bermudan options

We introduce a new method to calculate the credit exposure of Bermudan,
discretely monitored barrier and European options. Core of the approach is the
application of the dynamic Chebyshev method of Glau et al. (2019). The dynamic
Chebyshev method delivers a closed form approximation of the option prices
along the paths together with the options' delta and gamma. Key advantage is
the polynomial structure of the approximation, which allows us a highly
efficient evaluation of the credit exposures, even for a large number of
simulated paths. The approach is highly flexible in the model choice, payoff
profiles and asset classes. We compute the exposure profiles for Bermudan and
barrier options in three different equity models and compare them to the
profiles of European options. The analysis reveals potential shortcomings of
common simplifications in the exposure calculation. The proposed method is
sufficiently simple and efficient to avoid such risk-bearing simplifications.
