$\kappa$ the connectivity of $G$. In 1989, Bauer, Broersma Li and Veldman
proved that if $G$ is a 2-connected graph with $d(x)+d(y)+d(z)\ge n+\kappa$ for
all triples $x,y,z$ of independent vertices, then $G$ is hamiltonian. In this
paper we improve this result by reducing the lower bound $n+\kappa$ to
$p+\kappa$.

impact on the physical and chemical evolution of its surroundings. In this work
we demonstrate that a dynamic, fast flavor oscillation wave can develop
spontaneously in a one-dimensional (1D) neutrino gas when the angular
distributions of the electron neutrino and antineutrino cross each other.
Unlike the 2D stationary models which are plagued with small-scale flavor
structures, the fast flavor oscillation waves remain coherent in the dynamic 1D
model in both the position and momentum spaces of the neutrino. The electron
lepton number is redistributed and transported in space as the flavor
oscillation wave propagates, although the total lepton number remains constant.
This result may have interesting implications in the neutrino emission in and
the evolution of the compact objects such as core-collapse supernovae.

two-to-two scattering processes involving scalars and photons as external
particles. We construct a minimal basis of interaction monomials capturing all
contributions to these processes. This classification goes beyond the
expansions used in effective field theory since it retains the most general
momentum dependence in the propagators and couplings. In this way, we derive
the most general scattering amplitudes compatible with a relativistic quantum
field theory. Comparing to tree-level scattering in general relativity, we
identify the differential cross sections which are generated by the non-trivial
momentum dependence of the interaction vertices.

from quantum metrology together with the study of the quantum correlations
embedded in the system at finite temperatures. Within this frame we examine the
spin-$1/2$ XY chain, first estimating, by means of the quantum Fisher
information, the lowest attainable bound on the temperature precision. We then
address the estimation of the temperature of the sample from the analysis of
correlations using a quantum non demolishing Faraday spectroscopy method.
Finally, we demonstrate that for sufficiently low temperatures the proposed
measurements are optimal to estimate accurately the temperature of the sample.

stability of equilibria of a sigmoidal system is determined by a combinatorial
analysis of the limiting switching system with piece-wise constant
non-linearities. In addition, we describe a local decomposition of a switching
system into a product of simpler cyclic feedback systems, where the cycles in
each decomposition correspond to a particular subset of network loops.

resolve halos across a wide range of masses and environments, from massive
galaxy clusters down to normal galaxies, while following a large variety of
physical processes (star formation, chemical enrichment, AGN feedback) to allow
a self-consistent comparison to observations at multiple wavelengths. Using the
Magneticum simulations, we investigate the buildup of the diffuse stellar
component (DSC) around massive galaxies within group and cluster environments.
The DSC in our simulations reproduces the spatial distribution of the observed
intracluster light (ICL) as well as its kinematic properties remarkably well.
For galaxy clusters and groups we find that, although the DSC in almost all
cases shows a clear separation from the brightest cluster galaxy (BCG) with
regard to its dynamic state, the radial stellar density distribution in many
halos is often characterized by a single Sersic profile, representing both the
BCG component and the DSC, very much in agreement with current observational
results. Interestingly, even in those halos that clearly show two components in
both the dynamics and the spatial distribution of the stellar component, no
correlation between them is evident.

transition whereby a material in an initially solid-like state then yields
plastically. Major unresolved questions concern whether any material will yield
smoothly and gradually (ductile behaviour) or fail abruptly and
catastrophically (brittle behaviour); the roles of sample annealing, disorder
and shear band formation in the onset of yielding and failure; and, most
importantly from a practical viewpoint, whether any impending catastrophic
failure can be anticipated before it happens. We address these questions by
studying the yielding of slowly sheared athermal amorphous materials, within a
minimal mesoscopic lattice elastoplastic model. Our contributions are fourfold.
First, we elucidate whether yielding will be ductile or brittle, for any given
level of sample annealing. Second, we show that yielding comprises two distinct
stages: a pre-failure stage, in which small levels of strain heterogeneity
slowly accumulate, followed by a catastrophic brittle failure event, in which a
crack quickly propagates across the sample via a cooperating line of plastic
events. Third, we provide an expression for the slowly growing level of strain
heterogeneity in the pre-failure stage, expressed in terms of the macroscopic
stress-strain curve and the sample size, and in excellent agreement with our
simulation results. Fourth, we elucidate the basic mechanism via which a crack
then nucleates and provide an approximate expression for the probability
distribution of shear strains at which failure occurs, as determined by the
disorder inherent in the sample, expressed in terms of a single annealing
parameter, and the system size.

publishing. Firstly, we introduce Lakat, a novel base layer for a publishing
system that fosters collaboration, pluralism and permissionless participation.
Drawing inspiration from the philosophy of Imre Lakatos, Lakat is designed as a
peer-to-peer process- and conflict-oriented system that supports continuous
integration across multiple branches. This architecture provides a robust
foundation for the integration of existing reputation systems and incentive
structures or the development of new ones. Secondly, we propose a new consensus
mechanism, called Proof of Review, which ensures the integrity and quality of
the content while promoting active participation from the community. Lastly, we
present Lignification, a new finality gadget specifically designed for
branched, permissionless systems. Lignification provides a deterministic way to
find the consensual state in these systems, ensuring the system's robustness
and reliability in handling complex scenarios where multiple contributors may
be proposing changes simultaneously. Together, these contributions aim to
provide a convenient starting point to tackle some of the issues in traditional
paper-formatted publishing of research output. By prioritizing collaboration,
process-orientation, and pluralism, Lakat aims to improve the way research is
conducted and disseminated and ultimately hopes to contribute to a healthier
and more productive academic culture.

information about nonequilibrium dynamics of excitations in materials. In a
typical experiment of time-resolved x-ray absorption spectroscopy, the systems
are excited by a femtosecond laser pulse (pump pulse) followed by an x-ray
(probe pulse) after a time delay to measure the absorption spectra of the
photoexcited systems. We present a theory for nonequilibrium x-ray absorption
spectroscopy in one-dimensional strongly correlated systems. The core hole
created by x-ray is modeled as an additional effective potential of the core
hole site which changes the spectrum qualitatively. In equilibrium, the
spectrum reveals the charge gap at half-filling and the metal-insulator
transition in the presence of the core hole effect. Furthermore, a pump-probe
scheme is introduced to drive the system out of equilibrium before the x-ray
probe. The effects of the pump pulse with varying frequencies, shapes and
fluences are discussed for the dynamics of strongly correlated systems in and
out of resonance. The spectrum indicates that the driven insulating state has a
metallic droplet around the core hole. The rich structures of the
nonequilibrium x-ray absorption spectrum give more insight into the dynamics of
electronic structures.

autonomous and able to perform complex actions. However, the problem of
navigation for agents with limited (or no) perception of the world, or devoid
of a fully defined motion model, has received little attention from research in
AI and Robotics. One way to tackle this problem is to use guided navigation, in
which other autonomous agents, endowed with perception, can combine their
distinct viewpoints to infer the localisation and the appropriate commands to
guide a sensory deprived agent through a particular path. Due to the limited
knowledge about the physical and perceptual characteristics of the guided
agent, this task should be conducted on a level of abstraction allowing the use
of a generic motion model, and high-level commands, that can be applied by any
type of autonomous agents, including humans. The main task considered in this
work is, given a group of autonomous agents perceiving their common environment
with their independent, egocentric and local vision sensors, the development
and evaluation of algorithms capable of producing a set of high-level commands
(involving qualitative directions: e.g. move left, go straight ahead) capable
of guiding a sensory deprived robot to a goal location.

Silicon Detectors (RSDs) and measurements of the temporal and spatial
resolutions using a combined analysis of laser and beam test data. RSDs are a
new type of n-in-p silicon sensor based on the Low-Gain Avalanche Diode (LGAD)
technology, where the $n^+$ implant has been designed to be resistive, and the
read-out is obtained via AC-coupling. The truly innovative feature of RSD is
that the signal generated by an impinging particle is shared isotropically
among multiple read-out pads without the need for floating electrodes or an
external magnetic field. Careful tuning of the coupling oxide thickness and the
$n^+$ doping profile is at the basis of the successful functioning of this
device. Several RSD matrices with different pad width-pitch geometries have
been extensively tested with a laser setup in the Laboratory for Innovative
Silicon Sensors in Torino, while a smaller set of devices have been tested at
the Fermilab Test Beam Facility with a 120 GeV/c proton beam. The measured
spatial resolution ranges between $2.5\; \mu m$ for 70-100 pad-pitch geometry
and $17\; \mu m$ with 200-500 matrices, a factor of 10 better than what is
achievable in binary read-out ($bin\; size/ \sqrt{12}$). Beam test data show a
temporal resolution of $\sim 40\; ps$ for 200-$\mu m$ pitch devices, in line
with the best performances of LGAD sensors at the same gain.

hydrogen (HI) emission in the Southern sky covering declinations $\delta \leq
1^{\circ}$ using the Parkes Radio Telescope. The survey covers $2\pi$
steradians with an effective angular resolution of ~16', at a velocity
resolution of 1.0 km/s, and with an rms brightness temperature noise of 57 mK.
GASS is the most sensitive, highest angular resolution survey of Galactic HI
emission ever made in the Southern sky. In this paper we outline the survey
goals, describe the observations and data analysis, and present the first-stage
data release. The data product is a single cube at full resolution, not
corrected for stray radiation. Spectra from the survey and other data products
are publicly available online.

good many conserved $p$-form currents with various $p$. The last fact, being in
tension with `no nontrivial conserved currents in quantum gravity' and similar
statements, gives an indication of hidden integrability of the models. Our
results rely on a systematic computation of Hochschild, cyclic, and
Chevalley--Eilenberg cohomology for the corresponding higher spin algebras. A

zeros of random (distributed according to the Kostlan distribution) polynomials
in $\mathbb{R}\mathrm{P}^n$. Using a random spectral sequence, we prove an
asymptotically exact estimate on the expected number of connected components in
the complement of $s$ such hypersurfaces in $\mathbb{R}\mathrm{P}^n$. We also
investigate the same problem in the case where the hypersurfaces are defined by
random quadratic polynomials. In this case, we establish a connection between
the Betti numbers of such arrangements with the expected behavior of a certain
model of a randomly defined geometric graph. While our general result implies
that the average zeroth Betti number of the union of random hypersurface
arrangements is bounded from above by a function that grows linearly in the
number of polynomials in the arrangement, using the connection with random
graphs, we show an upper bound on the expected zeroth Betti number of random
quadrics arrangements that is sublinear in the number of polynomials in the
arrangement. This bound is a consequence of a general result on the expected
number of connected components in our random graph model which could be of
independent interest.

framework for time-evolution methods and optimisation methods in the context of
matrix product states. In particular, we introduce a new integration scheme for
studying time-evolution, which can cope with arbitrary Hamiltonians, including
those with long-range interactions. Rather than a Suzuki-Trotter splitting of
the Hamiltonian, which is the idea behind the adaptive time-dependent density
matrix renormalization group method or time-evolving block decimation, our
method is based on splitting the projector onto the matrix product state
tangent space as it appears in the Dirac-Frenkel time-dependent variational
principle. We discuss how the resulting algorithm resembles the density matrix
renormalization group (DMRG) algorithm for finding ground states so closely
that it can be implemented by changing just a few lines of code and it inherits
the same stability and efficiency. In particular, our method is compatible with
any Hamiltonian for which DMRG can be implemented efficiently and DMRG is
obtained as a special case of imaginary time evolution with infinite time step.

concurrent vector field on a Finsler manifold. We show that some special
Finsler manifolds admitting such vector fields turn out to be Riemannian. We
prove that Tachibana's characterization of Finsler manifolds admitting a
concurrent vector field leads to Riemannain metrics. We give an answer to the
question raised in \cite{DWF}: "Is any n-dimensional Finsler manifold $(M,F)$,
admitting a non-constant smooth function $f$ on $M$ such that $\frac{\partial
f}{\partial x^i}\frac{\partial g^{ij}}{\partial y^k}=0$, a Riemannian
manifold?". Various examples for conic Finsler and Riemannian spaces that admit
semi-concurrent vector field are presented. Finally, we conjectured that there
is no regular Finsler non-Riemannian metric that admits a semi-concurrent
vector field. In other words, a Finsler metric admitting a semi-concurrent
vector field is necessarily either Riemannian or conic Finslerian.

system, PAndAS-48, in the outskirts of the M31 halo. Our photometry reveals
this object to be comprised of an ancient and very metal-poor stellar
population with age > 10 Gyr and [Fe/H] < -2.3. Our inferred distance modulus
of 24.57 +/- 0.11 confirms that PAndAS-48 is most likely a remote M31 satellite
with a 3D galactocentric radius of 149 (+19 -8) kpc. We observe an apparent
spread in color on the upper red giant branch that is larger than the
photometric uncertainties should allow, and briefly explore the implications of
this. Structurally, PAndAS-48 is diffuse, faint, and moderately flattened, with
a half-light radius rh = 26 (+4 -3) pc, integrated luminosity Mv = -4.8 +/-
0.5, and ellipticity = 0.30 (+0.08 -0.15). On the size-luminosity plane it
falls between the extended globular clusters seen in several nearby galaxies,
and the recently-discovered faint dwarf satellites of the Milky Way; however,
its characteristics do not allow us to unambiguously class it as either type of
system. If PAndAS-48 is a globular cluster then it is the among the most
elliptical, isolated, and metal-poor of any seen in the Local Group, extended
or otherwise. Conversely, while its properties are generally consistent with
those observed for the faint Milky Way dwarfs, it would be a factor ~2-3
smaller in spatial extent than any known counterpart of comparable luminosity.

deduce a surprising property of macroscopic dimension, and we give two
applications to positive scalar curvature and characteristic classes,
respectively.

ground-state delocalization-localization transitions driven by quasiperiodicity
in interacting fermionic chains. In the presence of interactions, these
transitions separate Luttinger Liquid and Anderson glass phases. Remarkably,
close to criticality, we find that excitations become effectively
non-interacting. By formulating a many-body generalization of a recently
developed method to obtain single-particle localization phase diagrams, we
carry out precise calculations of critical points between Luttinger Liquid and
Anderson glass phases and find that the correlation length critical exponent
takes the value $\nu = 1.001 \pm 0.007$, compatible with $\nu=1$ known exactly
at the non-interacting critical point. We also show that other critical
exponents, such as the dynamical exponent $z$ and a many-body analog of the
fractal dimension are compatible with the exponents obtained at the
non-interacting critical point. Noteworthy, we find that the transitions are
accompanied by the emergence of a many-body generalization of previously found
single-particle hidden dualities. Finally, we show that in the limit of
vanishing interaction strength, all finite range interactions are irrelevant at
the non-interacting critical point.

important for understanding the underlying dynamics of cardiac anatomical
structures. Many methods explicitly impose smoothness constraints such as the
$\mathcal{L}_2$ norm on the displacement vector field (DVF), while usually
ignoring biomechanical feasibility in the transformation. Other geometric
constraints either regularize specific regions of interest such as imposing
incompressibility on the myocardium or introduce additional steps such as
training a separate network-based regularizer on physically simulated datasets.
In this work, we propose an explicit biomechanics-informed prior as
regularization on the predicted DVF in modeling a more generic biomechanically
plausible transformation within all cardiac structures without introducing
additional training complexity. We validate our methods on two publicly
available datasets in the context of 2D MRI data and perform extensive
experiments to illustrate the effectiveness and robustness of our proposed
methods compared to other competing regularization schemes. Our proposed
methods better preserve biomechanical properties by visual assessment and show
advantages in segmentation performance using quantitative evaluation metrics.

Completely covered VRI band light curves and four times of minimum light were
obtained. Combining the photometric and previously published radial velocity
data, a revised photometric analysis was carried out for the binary system by
applying the Wilson-Devinney code. With a hot spot placed on the massive
primary component near the neck region of the common envelope, the light curves
were satisfactorily modeled. The photometric solution combined with the radial
velocity solution reveals that XZ Leo is an A-type contact binary with a degree
of contact of 24($\pm1)\%$. The absolute parameters of the components were
determined as M_1 = 1.74($\pm$0.06)M_\odot, M_2 = 0.61($\pm$0.02)M_\odot, R_1 =
1.69($\pm$0.01)R_\odot, R_2 = 1.07($\pm0.01$)R_\odot, L_1 = 6.73($\pm0.08$)
L_\odot, L_2 = 2.40($\pm$0.04)L_\odot. Based on all the available data, the
long-term orbital period behavior of the system was investigated. It indicates
that the binary system was undergoing continuous orbital period increase in the
past three decades with a rate of dP/dt = + 6.12 \times {10^{-8}} days yr^{-1},
which suggests a probable mass transfer from the secondary to the primary
component at a rate of dM/dt= 3.92\times 10^{-8} M_\odot yr^{-1}. The binary
system is expected to evolve into the broken-contact stage in $1.56 \times
10^6$ years. This could be evidence supporting the Thermal Relaxation
Oscillation theory.

crossover regime of a superfluid Fermi gas | 24 pages, 8 figures | Phys. Rev. A 93, 013610 (2016) | 10.1103/PhysRevA.93.013610 | null | cond-mat.quant-gas | http://arxiv.org/licenses/nonexclusive-distrib/1.0/ | We theoretically investigate the uniform spin susceptibility $\chi$ in the
superfluid phase of an ultracold Fermi gas in the BCS
(Bardeen-Cooper-Schrieffer)-BEC (Bose-Einstein condensation) crossover region.
In our previous paper [H. Tajima, {\it et. al.}, Phys. Rev. A {\bf 89}, 033617
(2014)], including pairing fluctuations within an extended $T$-matrix
approximation (ETMA), we showed that strong pairing fluctuations cause the
so-called spin-gap phenomenon, where $\chi$ is anomalously suppressed even in
the normal state near the superfluid phase transition temperature $T_{\rm c}$.
In this paper, we extend this work to the superfluid phase below $T_{\rm c}$,
to clarify how this many-body phenomenon is affected by the superfluid order.
From the comparison of the ETMA $\chi$ with the Yosida function describing the
spin susceptibility in a weak-coupling BCS superfluid, we identify the region
where pairing fluctuations crucially affect this magnetic quantity below
$T_{\rm c}$ in the phase diagram with respect to the strength of a pairing
interaction and the temperature. This spin-gap regime is found to be consistent
with the previous pseudogap regime determined from the pseudogapped density of
states. We also compare our results with a recent experiment on a $^6$Li Fermi
gas. Since the spin susceptibility is sensitive to the formation of
spin-singlet preformed pairs, our results would be useful for the study of
pseudogap physics in an ultracold Fermi gas on the viewpoint of the spin
degrees of freedom.

in the realistic imbalanced scenario. To build connections between existing
many-shot intents and few-shot intents, we consider an intent as a combination
of a domain and an action, and propose a composed variational natural language
generator (CLANG), a transformer-based conditional variational autoencoder.
CLANG utilizes two latent variables to represent the utterances corresponding
to two different independent parts (domain and action) in the intent, and the
latent variables are composed together to generate natural examples.
Additionally, to improve the generator learning, we adopt the contrastive
regularization loss that contrasts the in-class with the out-of-class utterance
generation given the intent. To evaluate the quality of the generated
utterances, experiments are conducted on the generalized few-shot intent
detection task. Empirical results show that our proposed model achieves
state-of-the-art performances on two real-world intent detection datasets.

measuring the neutron spin structure functions with maximal theoretical control
of nuclear effects. We calculate the nuclear structure factors in the
longitudinal double-spin asymmetries using methods of light-front nuclear
structure. A unique feature of the spin-1 system is that spin asymmetries can
be formed either relative to the cross section in all three spin states
($\lambda_d = \pm 1, 0$) or in the two maximum-spin states only ($\pm 1$,
involving tensor polarization). We find that the two-state deuteron spin
asymmetry at small spectator proton momenta permits accurate extraction of the
neutron structure function $g_{1n}$. Such measurements could be performed at a
future electron-ion collider (EIC) with polarized deuteron beams and suitable
forward detectors.

arXiv:2101.02282 | null | null | null | cs.RO | http://arxiv.org/licenses/nonexclusive-distrib/1.0/ | Autonomous navigation of steel bridge inspection robots is essential for
proper maintenance. The majority of existing robotic solutions for steel bridge
inspection requires human intervention to assist in the control and navigation.
In this paper, a control and navigation framework has been proposed for the
steel bridge inspection robot developed by the Advanced Robotics and Automation
(ARA)to facilitate autonomous real-time navigation and minimize human
intervention. The ARA robot is designed to work in two modes: mobile and
inch-worm. The robot uses mobile mode when moving on a plane surface and
inch-worm mode when jumping from one surface to the other. To allow the ARA
robot to switch between mobile and inch-worm modes, a switching controller is
developed with 3D point cloud data based. The surface detection algorithm is
proposed to allow the robot to check the availability of steel surfaces (plane,
area, and height) to determine the transformation from mobile mode to inch-worm
one. To have the robot safely navigate and visit all steel members of the
bridge, four algorithms are developed to process the data from a depth camera,
segment it into clusters, estimate the boundaries, construct a graph
representing the structure, generate the shortest inspection path with any
starting and ending points, and determine available robot configuration for
path planning. Experiments on steel bridge structures setup highlight the
effective performance of the algorithms, and the potential to apply to the ARA
robot to run on real bridge structures.

frequency separation paradigm, for a recently proposed novel active suspension,
the Parallel Active Link Suspension (PALS). The developed mu-synthesis control
scheme is superior to the conventional H-infinity control, previously designed
for the PALS, in terms of ride comfort and road holding (higher frequency
dynamics), with important realistic uncertainties, such as in vehicle payload,
taken into account. The developed PID control method is applied to guarantee
good chassis attitude control capabilities and minimization of pitch and roll
motions (low frequency dynamics). A multi-objective control method, which
merges the aforementioned PID and mu-synthesis-based controls is further
introduced to achieve simultaneously the low frequency mitigation of attitude
motions and the high frequency vibration suppression of the vehicle. A
seven-degree-of-freedom Sport Utility Vehicle (SUV) full car model with PALS,
is employed in this work to test the synthesized controller by nonlinear
simulations with different ISO-defined road events and variable vehicle
payload. The results demonstrate the control scheme's significant robustness
and performance, as compared to the conventional passive suspension as well as
the actively controlled PALS by conventional H-infinity control, achieved for a
wide range of vehicle payload considered in the investigation.

sphere $S^4_N$ in the semi-classical limit. The space of functions can be
identified with functions on classical $S^4$ taking values in a higher spin
algebra associated to $\mathfrak{so}(5)$. We derive an explicit and complete
classification of the scalars and one-forms on the semi-classical limit of
$S_N^4$. The resulting kinematics is reminiscent of Vasiliev theory. Yang-Mills
matrix models naturally provide an action formulation for higher spin gauge
theory on $S^4$, with 4 irreducible modes for each spin $s\geq 1$. We
diagonalize the quadratic part of the effective action and exactly evaluate the
quadratic part in the spin 2 sector. By identifying the linear perturbation of
the effective metric, we obtain the exact kinetic term for all graviton
candidates. At the classical level, matter $T_{\mu\nu}$ leads to three
different contributions to the linearized metric: one consistent with
linearized GR, one more rapidly decreasing contribution, and one
non-propagating contribution localized at $T_{\mu\nu}$. The latter is too large
to be physically acceptable, unless there is a significant induced quantum
action. This issue should be resolved on generalized fuzzy spaces.

platform to successfully localise itself in the environment. For decentralised
VPR applications where the visual data has to be transmitted between several
agents, the communication channel may restrict the localisation process when
limited bandwidth is available. JPEG is an image compression standard that can
employ high compression ratios to facilitate lower data transmission for VPR
applications. However, when applying high levels of JPEG compression, both the
image clarity and size are drastically reduced. In this paper, we incorporate
sequence-based filtering in a number of well-established, learnt and non-learnt
VPR techniques to overcome the performance loss resulted from introducing high
levels of JPEG compression. The sequence length that enables 100% place
matching performance is reported and an analysis of the amount of data required
for each VPR technique to perform the transfer on the entire spectrum of JPEG
compression is provided. Moreover, the time required by each VPR technique to
perform place matching is investigated, on both uniformly and non-uniformly
JPEG compressed data. The results show that it is beneficial to use a highly
compressed JPEG dataset with an increased sequence length, as similar levels of
VPR performance are reported at a significantly reduced bandwidth. The results
presented in this paper also emphasize that there is a trade-off between the
amount of data transferred and the total time required to perform VPR. Our
experiments also suggest that is often favourable to compress the query images
to the same quality of the map, as more efficient place matching can be
performed. The experiments are conducted on several VPR datasets, under mild to
extreme JPEG compression.

contain at least one metal-to-carbon bond in which the carbon is part of an
organic group. They have played a major role in the development of the science
of chemistry. These compounds are used to a large extent as catalysts
(substances that increase the rate of reactions without themselves being
consumed) and as intermediates in the laboratory and in industry. Recently,
novel quantum phenormena such as topological insulators and superconductors
were also suggested in these materials. However, there has been no report on
the experimental exploration for the topological state. Evidence for
superconductivity from the zero-resistivity state in any organometallic
compound has not been achieved yet, though much efforts have been devoted. Here
we report the experimental realization of superconductivity with the critical
temperature of 3.6 K in a potassium-doped organometallic compound, $ i.e.$
tri-$o$-tolylbismuthine with the evidence of both the Meissner effect and the
zero-resistivity state through the $dc$ and $ac$ magnetic susceptibility and
resistivity measurements. The obtained superconducting parameters classify this
compound as a type-II superconductor. The benzene ring is identified to be the
essential superconducting unit in such a phenyl organometallic compound. The
superconducting phase and its composition are determined by the combined
studies of the X-ray diffraction and theoretical calculations as well as the
Raman spectroscopy measurements. These findings enrich the applications of
organometallic compounds in superconductivity and add a new electron-acceptor
family for organic superconductors. This work also points to a large pool for
finding superconductors from organometallic compounds.

The orbits of large
particles are mainly governed by Martian gravity, while those of small
particles could be significantly affected by non-gravitational forces. Many of
the previous studies of particle dynamics around Mars have focused on
relatively small particles (radius of $r_{\rm p} \lesssim 100 \, \mu m$) for
$\lesssim 10^{4}$ years. In this paper, using direct numerical orbital
integration and analytical approaches, we consider Martian gravity, Martian
$J_{2}$, the solar radiation pressure (SRP) and the Poynting-Robertson (PR)
force to study the giga-year dynamical evolution of particles orbiting near the
Martian equatorial plane with radius ranging from micrometer to meter. We also
newly study the effect of the planetary shadow upon the particle dynamics. Our
results show that small particles ($r_{\rm p} \lesssim 10 \, \mu m$) initially
at $\lesssim 8$ Martian radii (below the orbit of today's Deimos) are quickly
removed by the SRP due to eccentricity increase, resulting in a collision with
Mars at the pericenter distnace. The orbits of larger particles ($r_{\rm p} >
10 \, \mu m$) slowly decay due to the PR forces (timescale of $> 10^{4}$
years). The planetary shadow reduces the sunlit area in the orbit and thus the
efficiency of the PR drag force is reduced. However, we show that, even
including the planetary shadow, particles up to $\sim 10$ cm in radius,
initially at $\lesssim 8$ Martian radii, eventually spiral onto the Martian
surface within $\sim 10^{9}$ years. Smaller particles require less time to
reach Mars, and vice versa. Our results would be important to better understand
and constrain the nature of the remaining particle around Mars in a context of
giant impact hypothesis for the formation of Phobos and Deimos.

two-dimensional ion crystals provides the foundation for the use of such
structures for quantum simulation purposes. We present a combined experimental
and theoretical study of two-dimensional ion crystals. We demonstrate that
standard pseudopotential theory accurately predicts the positions of the ions
and the location of structural transitions between different crystal
configurations. However, pseudopotential theory is insufficient to determine
eigenfrequencies of the two-dimensional ion crystals accurately but shows
significant deviations from the experimental data obtained from resolved
sideband spectroscopy. Agreement at the level of 2.5 x 10^(-3) is found with
the full time-dependent Coulomb theory using the Floquet-Lyapunov approach and
the effect is understood from the dynamics of two-dimensional ion crystals in
the Paul trap. The results represent initial steps towards an exploitation of
these structures for quantum simulation schemes.

systems. The goal of port scanning is to identify active services and
associated information. Although this technique is often employed by malicious
actors to locate vulnerable systems within a network, port scanning is also a
legitimate method employed by IT professionals to troubleshoot network issues
and maintain system security. In the case of the latter, cybersecurity
practitioners use port scanning catalog exposed systems, identify potential
misconfigurations, or test controls that may be running on a system. Existing
literature has thoroughly established a taxonomy for port scanning. The
taxonomy maps the types of scans as well as techniques. In fact, there are
several tools mentioned repeatedly in the literature. Those are Nmap, Zmap, and
masscan. Further, the presence of multiple tools signals that how a port
scanner interacts with target systems impacts the output of the tool. In other
words, the various tools may not behave identically or produce identical
output. Yet, no work has been done to quantify the efficacy for these popular
tools in a uniform, rigorous manner. Accordingly, we used a comparative
experimental protocol to measure the accuracy, false positive, false negative,
and efficiency of Nmap, Zmap, and masscan. The results show no difference
between port scanners in general performance. However, the results revealed a
statistically significant difference in efficiency. This information can be
used to guide the selection of port scanning tools based on specific needs and
requirements. As well, for researchers, the outcomes may also suggest areas for
future work in the development novel port scanning tools.

terms of a parameterized resampling mechanism. We find that a suitably
generalized notion of the Effective Sample Size (ESS), widely used to monitor
algorithm degeneracy, appears naturally in a study of its convergence
properties. We are then able to phrase sufficient conditions for time-uniform
convergence in terms of algorithmic control of the ESS, in turn achievable by
adaptively modulating the interaction between particles. This leads us to
suggest novel algorithms which are, in senses to be made precise, provably
stable and yet designed to avoid the degree of interaction which hinders
parallelization of standard algorithms. As a byproduct, we prove time-uniform
convergence of the popular adaptive resampling particle filter.

auto-segmentation to reduce the time cost for physicians to edit contours.
However, deep learning (DL)-based direct segmentation of CBCT images is a
challenging task, mainly due to the poor image quality and lack of
well-labelled large training datasets. Deformable image registration (DIR) is
often used to propagate the manual contours on the planning CT (pCT) of the
same patient to CBCT. In this work, we undertake solving the problems mentioned
above with the assistance of DIR. Our method consists of three main components.
First, we use deformed pCT contours derived from multiple DIR methods between
pCT and CBCT as pseudo labels for initial training of the DL-based direct
segmentation model. Second, we use deformed pCT contours from another DIR
algorithm as influencer volumes to define the region of interest for DL-based
direct segmentation. Third, the initially trained DL model is further
fine-tuned using a smaller set of true labels. We found that DL-based direct
segmentation on CBCT trained with pseudo labels and without influencer volumes
shows poor performance compared to DIR-based segmentation. However, adding
deformed pCT contours as influencer volumes in the direct segmentation network
dramatically improves segmentation performance, reaching the accuracy level of
DIR-based segmentation. The DL model with influencer volumes can be further
improved through fine-tuning using a smaller set of true labels. Experiments
showed that 7 out of 19 structures have an at least 0.2 Dice similarity
coefficient increase compared to DIR-based segmentation. A DL-based direct CBCT
segmentation model can be improved to outperform DIR-based segmentation models
by using deformed pCT contours as pseudo labels and influencer volumes for
initial training, and by using a smaller set of true labels for model fine
tuning.

computational fluid dynamics method that utilizes a Riemann solver and achieves
the second-order accuracy in space. In this paper, we extend the Godunov SPH
method to elastic dynamics by incorporating deviatoric stress tensor that
represents the stress for shear deformation or anisotropic compression.
Analogously to the formulation of the original Godunov SPH method, we formulate
the equation of motion, the equation of energy, and the time evolution equation
of deviatoric stress tensor so that the resulting discretized system achieves
the second-order accuracy in space. The standard SPH method tends to suffer
from the tensile instability that results in unphysical clustering of particles
especially in tension-dominated region. We find that the tensile instability
can be suppressed by selecting appropriate interpolation for density
distribution in the equation of motion for the Godunov SPH method even in the
case of elastic dynamics. Several test calculations for elastic dynamics are
performed, and the accuracy and versatility of the present method are shown.

Despite many advances in the microscopic understanding of the ordered states, a
more nuanced and profound question often remains unanswered: how do the
collective excitations influence the electronic order formation? Here, we
experimentally show that a phonon affects the spin density wave (SDW) formation
after an SDW-quench by femtosecond laser pulses. In a thin film, the
temperature-dependent SDW period is quantized, allowing us to track the
out-of-equilibrium formation path of the SDW precisely. By exploiting its
persistent coupling to the lattice, we probe the SDW through the transient
lattice distortion, measured by femtosecond X-ray diffraction. We find that
within 500 femtoseconds after a complete quench, the SDW forms with the
low-temperature period, directly bypassing a thermal state with the
high-temperature period. We argue that a momentum-matched phonon launched by
the quench changes the formation path of the SDW through the dynamic pinning of
the order parameter.

ontology language such as ELI or certain TGDs and (2) replace the database with
one from a tractable class such as the class of databases whose treewidth is
bounded by a constant. We determine the computational complexity and the
relative completeness of the resulting approximations. (Almost) all of them
reduce the data complexity from coNP-complete to PTime, in some cases even to
fixed-parameter tractable and to linear time. While approximations of kind (1)
also reduce the combined complexity, this tends to not be the case for
approximations of kind (2). In some cases, the combined complexity even
increases.

coupling promotes the effects of electronic correlations owing to the Mo$^{4+}$
$d^{2}$ electronic configuration, producing a correlated metallic phase far
from the Mott state. The contraindication between metallicity and polar
distortions is thereby alleviated through the renormalized quasiparticles,

computational logics, where meanings of sentences are represented by pieces of
quantum information (generally, density operators of some Hilbert spaces),
which can be stored and transmitted by means of quantum particles. This
approach can be applied to a semantic characterization of epistemic logical
operations, which may occur in sentences like "At time t0 Bob knows that at
time t Alice knows that the spin-value is up". Each epistemic agent (say,
Alice, Bob,...) has a characteristic truth-perspective, corresponding to a
particular orthonormal basis of the Hilbert space C^2. From a physical point of
view, a truth-perspective can be associated to an apparatus that allows one to
measure a given observable. An important feature that characterizes the
knowledge of any agent is the amount of information that is accessible to
him/her (technically, a special set of density operators, which also represents
the internal memory of the agent in question). One can prove that interesting
epistemic operations are special examples of quantum channels, which generally
are not unitary. The act of knowing may involve some intrinsic irreversibility
due to possible measurement procedures or to a loss of information about the
environment. We also illustrate some relativistic-like effects that arise in
the behavior of epistemic agents.

arrangement of spherical metallic nanoparticles. Each nanoparticle supports
three degenerate dipolar localized surface plasmon (LSP) resonances. In the
regime where the interparticle distance is much smaller than the optical or
near-infrared wavelength associated with the LSPs, the latter couple through
the dipole-dipole interaction and form collective plasmonic modes which extend
over the whole metasurface. Within a Hamiltonian model which we solve exactly,
we derive general expressions which enable us to extract analytically the
quasistatic plasmonic dispersion for collective modes polarized within the
plane and perpendicular to the plane of the metasurface. Importantly, our
approach allows us not only to consider arbitrary Bravais lattices, but also
non-Bravais two-dimensional metacrystals featuring nontrivial topological
properties, such as, e.g., the honeycomb or Lieb lattices. Additionally, using
an open quantum system approach, we consider perturbatively the coupling of the
collective plasmons to both photonic and particle-hole environments, which
lead, respectively, to radiative and nonradiative frequency shifts and damping
rates, for which we provide closed-form expressions. The radiative frequency
shift, when added to the quasistatic dispersion relation, provides an
approximate analytical description of the fully retarded band structure of the
collective plasmons. While it is tempting to make a direct analogy between the
various systems which we consider and their electronic tight-binding
equivalents, we critically examine how the long-range retarded and anisotropic
nature of the dipole--dipole interaction may quantitatively and qualitatively
modify the underlying band structures and discuss their experimental
observability.

Precession Rate | accepted for publication in Icarus | null | 10.1016/j.icarus.2008.10.005 | null | astro-ph | http://arxiv.org/licenses/nonexclusive-distrib/1.0/ | We present 'empirical' models (pressure vs. density) of Saturn's interior
constrained by the gravitational coefficients J_2, J_4, and J_6 for different
assumed rotation rates of the planet. The empirical pressure-density profile is
interpreted in terms of a hydrogen and helium physical equation of state to
deduce the hydrogen to helium ratio in Saturn and to constrain the depth
dependence of helium and heavy element abundances. The planet's internal
structure (pressure vs. density) and composition are found to be insensitive to
the assumed rotation rate for periods between 10h:32m:35s and 10h:41m:35s. We
find that helium is depleted in the upper envelope, while in the high pressure
region (P >~ 1 Mbar) either the helium abundance or the concentration of
heavier elements is significantly enhanced. Taking the ratio of hydrogen to
helium in Saturn to be solar, we find that the maximum mass of heavy elements
in Saturn's interior ranges from ~ 6 to 20 M_Earth. The empirical models of
Saturn's interior yield a moment of inertia factor varying from 0.22271 to
0.22599 for rotation periods between 10h:32m:35s and 10h:41m:35s, respectively.
A long-term precession rate of about 0.754" yr^{-1} is found to be consistent
with the derived moment of inertia values and assumed rotation rates over the
entire range of investigated rotation rates. This suggests that the long-term
precession period of Saturn is somewhat shorter than the generally assumed
value of 1.77 x 10^6 years inferred from modeling and observations.

of giant exoplanets, is commonly explained by the accretion of nebular hydrogen
and helium onto a large core of terrestrial-like composition. The fate of this
core has important consequences for the evolution of the interior structure of
the planet. It has recently been shown that H2O, MgO and SiO2 dissolve in
liquid metallic hydrogen at high temperature and pressure. In this study, we
perform ab initio calculations to study the solubility of an innermost metallic
core. We find dissolution of iron to be strongly favored above 2000 K over the
entire pressure range (0.4-4 TPa) considered. We compare with and summarize the
results for solubilities on other probable core constituents. The calculations
imply that giant planet cores are in thermodynamic disequilibrium with
surrounding layers, promoting erosion and redistribution of heavy elements.
Differences in solubility behavior between iron and rock may influence
evolution of interiors, particularly for Saturn-mass planets. Understanding the
distribution of iron and other heavy elements in gas giants may be relevant in
understanding mass-radius relationships, as well as deviations in transport
properties from pure hydrogen-helium mixtures.

to thwart reverse engineering and IP theft. Logic locking is a promising
solution, but there are many open concerns. First, even when applied at a
higher level of abstraction, locking may result in significant overhead without
improving the security metric. Second, optimizing a security metric is
application-dependent and designers must evaluate and compare alternative
solutions. We propose a meta-framework to optimize the use of behavioral
locking during the high-level synthesis (HLS) of IP cores. Our method operates
on chip's specification (before HLS) and it is compatible with all HLS tools,
complementing industrial EDA flows. Our meta-framework supports different
strategies to explore the design space and to select points to be locked
automatically. We evaluated our method on the optimization of differential
entropy, achieving better results than random or topological locking: 1) we
always identify a valid solution that optimizes the security metric, while
topological and random locking can generate unfeasible solutions; 2) we
minimize the number of bits used for locking up to more than 90% (requiring
smaller tamper-proof memories); 3) we make better use of hardware resources
since we obtain similar overheads but with higher security metric.

theorem on simultaneous Diophantine approximation, from approximation of points
in $\mathbb R^m$ to approximation of systems of linear forms in $\mathbb
R^{nm}$. In this paper, we present an inhomogeneous version of the
Khintchine-Groshev theorem which does not carry a monotonicity assumption when
$nm>2$. Our results bring the inhomogeneous theory almost in line with the
homogeneous theory, where it is known by a result of Beresnevich and Velani
(2010) that monotonicity is not required when $nm>1$. That result resolved a
conjecture of Beresnevich, Bernik, Dodson, and Velani (2009), and our work
resolves almost every case of the natural inhomogeneous generalization of that
conjecture. Regarding the two cases where $nm=2$, we are able to remove
monotonicity by assuming extra divergence of a measure sum, akin to a linear
forms version of the Duffin-Schaeffer conjecture. When $nm=1$ it is known by
work of Duffin and Schaeffer (1941) that the monotonicity assumption cannot be
dropped.
The key new result is an independence inheritance phenomenon; the underlying
idea is that the sets involved in the $((n+k)\times m)$-dimensional
Khintchine-Groshev theorem ($k\geq 0$) are always $k$-levels more
probabilistically independent than the sets involved the $(n\times
m)$-dimensional theorem. Hence, it is shown that Khintchine's theorem itself
underpins the Khintchine-Groshev theory.

using synthetic narrow-band images of the Halpha emission line from zoom-in AMR
cosmological simulations of galaxies with stellar masses of $M \simeq 10^9
$Msun at redshifts z=2-7. In $\sim$50\% of the cases at redshifts lower than 4,
the gas inflow gives rise to star-forming, Halpha-bright, off-centre clumps.
Most of these clumps have gas metallicities, weighted by Halpha luminosity,
lower than the metallicity in the surrounding interstellar medium by $\sim$0.3
dex, consistent with observations of chemical inhomogeneities at high and low
redshifts. Due to metal mixing by shear and turbulence, these metallicity drops
are dissolved in a few disc dynamical times. Therefore, they can be considered
as evidence for rapid gas accretion coming from cosmological inflow of pristine
gas.

convex approximation. Unlike most existing studies where the trajectories are
assumed to be straight lines, we account for the effect of obstacles, such as
buildings, and deliberately avoid them during the trajectory planning phase.
Through extensive simulation experiments, we demonstrate that our proposed
approach can achieve significantly better energy efficiency than existing
benchmark algorithms.

Satnoianu | Flow- and Diffusion Distributed Structures with noise at the inlet | 31 pages, 14 figures, to appear in MatCom | null | null | null | nlin.PS | null | Flow and Diffusion Distributed Structures (FDS) are stationary spatially
periodic patterns that can be observed in reaction-diffusion-advection systems.
These structures arise when the flow rate exceeds a certain bifurcation point
provided that concentrations of interacting species at the inlet differ from
steady state values and the concentrations are held constant. Normally,
theoretical studies of these patterns are developed without concerning a noise.
In this paper we consider FDS for a more realistic conditions and assume that
the inlet concentrations are perturbed by a small noise. When the flow rate is
small, the FDS is linearly sensitive to noise at the inlet. Even weak
fluctuations destroy the stationary pattern and an oscillatory solution appears
instead. For higher flow rates the instability becomes nonlinear: the pattern
remains unaltered for a weak noise and undergoes the destruction when the noise
amplitude passes a certain threshold. We represent a detailed description of
these effects and examine two scenarios for the stabilization.

devices, which are moving in a specific city area, and establish time bounds
for the activation of a counter-measure, i.e., an antivirus or a cleaner in
order to prevent pandemic. More precisely, given an initial infected population
(mobile devices), we establish upper bounds on the time needed for a
counter-measure to take effect after infection (response-time), in order to
prevent the rest susceptible devices to get infected. Thus, within a period of
time, we guarantee that not all the susceptible devices in the city get
infected and the infected ones get sanitized. In our work, we first propose a
malware propagation model along with a device mobility model and then,
utilizing these models, we develop a simulator that we use to study the spread
of malware in such networks. Finally, we provide experimental results for the
pandemic prevention taken by our simulator for various response-time intervals.

an optimal high-$T_c$ superconductor La$_{2-x}$Sr$_x$CuO$_{4+y}$ tailored by
co-hole-doping. This is specifically done by varying the content of two very
different chemical species, Sr and O, respectively, in order to study the
influence of each. A superstructure known as staging is observed in all
samples, with the staging number $n$ increasing for higher Sr dopings $x$. We
find that the staging phases emerge abruptly with temperature, and can be
described as a second order phase transition with transition temperatures
slightly depending on the Sr doping. The Sr appears to correlate the
interstitial oxygen in a way that stabilises the reproducibility of the staging
phase both in terms of staging period and volume fraction in a specific sample.
The structural details as investigated in this letter appear to have no direct
bearing on the electronic phase separation previously observed in the same
samples. This provides new evidence that the electronic phase separation is
determined by the overall hole concentration rather than specific Sr/O content
and concommittant structural details.

identifying galaxy analogues in high-resolution dark matter simulations.
Subhalos identified by the AHF and ROCKSTAR halo finders have similar mass
functions, independent of resolution, but different radial distributions due to
significantly different subhalo hierarchies. We propose a simple way to
classify subhalos as galaxy analogues. The radial distributions of galaxy
analogues agree well at large halo-centric radii for both AHF and ROCKSTAR but
disagree near parent halo centres where the phase-space information used by
ROCKSTAR is essential.
We see clear mass segregation at small radii (within $0.5\,r_{vir}$) with
average galaxy analogue mass decreasing with radius. Beyond the virial radius,
we find a mild trend where the average galaxy analogue mass increases with
radius. These mass segregation trends are strongest in small groups and
dominated by the segregation of low mass analogues. The lack of mass
segregation in massive galaxy analogues suggests that the observed trends are
driven by the complex accretion histories of the parent halos rather than
dynamical friction.

many-body systems close to the ground state. Moreover, we also show that the
low-energy spectrum of the Bell operator associated to such systems can be well
approximated by the one of a quantum harmonic oscillator, and that
spin-squeezed states are optimal in displaying Bell correlations for such Bell
inequalities.

up of a body of water can be beneficial. We report first observation of a
counterpart of this intriguing fact, referred to as the Mpemba effect (ME),
during ordering in ferromagnets. By performing Monte Carlo simulations of a
generic model, we have obtained results on relaxation of systems that are
quenched to sub-critical state points from various temperatures above the
critical point. For a fixed final temperature, a system with higher starting
temperature equilibrates faster than the one prepared at a lower temperature,
implying the presence of ME. The observation is extremely counter-intuitive,
particularly because of the fact that the model has no in-built frustration or
metastability that typically is thought to provide ME. Via the calculations of
nonequilibrium properties concerning structure and energy, we quantify the role
of critical fluctuations behind this fundamental as well as technologically
relevant observation.
