In climate data analysis, this involves an accurate specification of measured quantities and a consequent analysis that consciously propagates the measurement errors at each step. The dissertation presents a thorough analytical method to quantify errors of measurement inherent in paleoclimate data. An additional focus are the uncertainties in assessing the coupling between different factors that influence the global mean temperature (GMT). Paleoclimate studies critically rely on `proxy variables' that record climatic signals in natural archives. However, such proxy records inherently involve uncertainties in determining the age of the signal. We present a generic Bayesian approach to analytically determine the proxy record along with its associated uncertainty, resulting in a time-ordered sequence of correlated probability distributions rather than a precise time series. We further develop a recurrence based method to detect dynamical events from the proxy probability distributions. The methods are validated with synthetic examples and demonstrated with real-world proxy records. The proxy estimation step reveals the interrelations between proxy variability and uncertainty. The recurrence analysis of the East Asian Summer Monsoon during the last 9000 years confirms the well-known `dry' events at 8200 and 4400 BP, plus an additional significantly dry event at 6900 BP. We also analyze the network of dependencies surrounding GMT. We find an intricate, directed network with multiple links between the different factors at multiple time delays. We further uncover a significant feedback from the GMT to the El Niño Southern Oscillation at quasi-biennial timescales. The analysis highlights the need of a more nuanced formulation of influences between different climatic factors, as well as the limitations in trying to estimate such dependencies"] | ['gnd:1074447662', 'gnd:4038971-6', 'gnd:4121894-2', 'gnd:4123037-1', 'gnd:4125276-7', 'gnd:4131193-0', 'gnd:4136907-5', 'gnd:4173112-8', 'gnd:4288494-9', 'gnd:4596948-6', 'gnd:4803995-0', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A832557773'] | ['Goswami, Bedartha', 'Methode', 'Wahrscheinlichkeitsverteilung', 'Datenanalyse', 'Mitteltemperatur', 'Datenauswertung', 'El-Niño-Phänomen', 'Paläoklimatologie', 'Paläoklima', 'Zirkulationsanomalie', 'Southern oscillation'] | 8 | 13,542 |

For Sub-Saharan Africa, especially the epidemiological situation is unclear, since comprehensive systems of mortality and health statistics are often absent. -- The economic analysis of health naturally places a special focus on the interrelation between health and economic well-being: the overall disease burden decreases when a country grows richer, and the share of communicable diseases decreases in the process of economic development, whereas the share of non-communicable diseases increases. In those parts of Sub-Saharan Africa that are mainly dominated by traditional subsistence farming, however, it is difficult to examine questions of income and health for simple fundamental reasons. A vital prerequisite for an empirical investigation is the thorough and accurate measurement of income. Yet, both the measurement of the burden of disease and the measurement of income are research tasks that are far from being fulfilled for Sub-Saharan Africa. A further issue that is related with economic well-being and health is education. For poor rural regions predominated by traditional subsistence farming it is far from clear whether investments in human capital are worthwhile. -- The present study addesses this research gap by producing empirical evidence on the measurement of the burden of disease, the structure of income, and returns to education in rural West Africa.

For instance, had mortgage contracts not been ill-designed in the sense that they facilitated deliberate defaults, the drag on the wider US housing market would have been less dramatic. Had large financial institutions not relied that heavily on short-term funding backed by US housing collateral, they might have been able to sufficiently roll over their obligations. Had the hoarding of liquid securities by prime brokers not harmed financial intermediation, the secured funding market might not have squeezed. Consequently, the investment bank Lehman Brothers would have possibly been intact today. No financial contagion would have been released. But unfortunately, all of these events did occur.

It is a global problem that has to be understood in the context of a globalising world with an increasing amount of goods being traded. This dissertation focuses on the interrelation between international trade and climate policies. It contributes to the literature from two perspectives: a demand side view by means of theoretical modelling, and a supply side view using numerical simulation. The first part of this dissertation uses general equilibrium trade models to analyse the effect of trade liberalisation on the environment. It shows that a trade-induced reallocation of production factors towards the most productive firms can explain part of sector-level changes in emission intensities. Moreover, if environmental policy is used strategically to substitute for trade policy, general equilibrium effects on firms’ markups need to be considered. The findings highlight that firm behaviour, factor reallocation across firms, and market structure all play a vital role for the impact of trade on the environment. The second part of this dissertation turns to the supply side of fossil fuels—the major source of greenhouse gas emissions. It shows that fossil fuels are globally abundant despite uncertainties in local supply, for instance of unconventional natural gas. It is hence not a physical scarcity that solves the problem of climate change. Accordingly, climate policy has to target the use of fossil fuels. While the use of natural gas may be consistent with the transformation towards a low carbon energy system, the phase-out of coal is integral for climate change mitigation. By means of numerical simulations, the relation between climate policy and the international trade in natural gas and steam coal is investigated. Moreover, this dissertation analyses to what extent major steam coal exporters have a self-interest in restricting their supply.'] | ['gnd:1025020073', 'gnd:4023222-0', 'gnd:7547705-1', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A836076753'] | ['Richter, Philipp M.', 'Handel', 'Klimaschutz'] | 19 | 13,550 |

These artificially created materials consist of periodically arranged sub-wavelength sized resonant structures. Their optical properties can be designed by changing the form, size or arrangement of the sub-structures. The resonator's interaction among each other and with an incident light-field is investigated experimentally in the terahertz regime of the electromagnetic spectrum. In the first part of this thesis the fundamental electromagnetic interaction between one type of sub-structure, a single Split-Ring resonator, is investigated in two dimensional arrays.Then the complexity of interaction was increased by adding a second Split-Ring inside each unit cell, which results in the formation of a particular kind of resonance, a so called Fano resonance. The line-shape of this sharp asymmetrically shaped resonance was then controlled by the separation between the two resonators.In the third part a new type of optical materials is presented, a wave vector selective surface.

An important task was the polycondensation of crystallizable long-chain diesters which are accessible by alkoxycarbonylation of unsaturated fatty acid esters to produce polyethylene-like polyesters with variable oligo ethylene segments. The polyesters were processed by injection molding, film extrusion and electrospinning. As an alternative to polycondensation which needs several hours of reaction time high molecular weight polyesters, polyurea-amides and polyurea-ester-amides were obtained by reactive extrusion within minutes by isocyanate-free polyaddition reactions in polymer melts. Polyaddition reactions of purified limonene dicarbonate were in the focus to make isocyanate-free linear high molecular weight polyurethanes, polyurethane networks and coatings accessible by the use of CO2.Together with the group of Prof. Mecking biobased α, ω-oligoethylene diesters with variable and crystallizable hydrocarbon segments were obtained by transesterification of fats with methanol and subsequent isomerizing alkoxycarbonylation in one step and successfully used in the polyester synthesis. These bio-based materials combine typical properties of polyethylene and polyesters. For the first time, high molecular weight and readily processable homo- and copolyesters became accessible by polycondensation with diols. It was possible to control their material properties by the oligo ethylene segment length. The polyethylene-like polyesters were obtained with melting temperatures above 100 °C, Young´s modules up to 400 MPa and values for the elongation at break of about 600 %. Electrospun nonwovens made from polyester solutions were biocompatible, biodegradable and suitable for cell colonization which was investigated in cooperation with Prof. Shastri´s group. By melt compounding films and phase-separated blends with other polyesters and polyolefins have been made available. Already 5 wt% polyester blended with PLA was sufficient to reduce the hydrophilicity and to enhance the resistance to hydrolysis.

Electrical discharge machining (EDM) is an electro-thermal machining process used to structure conductive materials. By applying a conductive layer (denoted as assisting electrode (AE)) on top of the non-conductive material, the EDM process can also be used to structure non-conductive ceramics. The EDM process starts with a discharge taking place between the tool electrode and the assisting electrode. During the process, carbon particles that are secreted from the dielectric oil are deposited on the newly exposed non-conductive ceramic surface forming a thin conductive layer. This intrinsic conductive layer (ICL) insures that the electric contact between the workpiece and the generator is maintained. After the machining process, the conductive layer can easily be removed for instance by heating.

In this thesis, we are investigating binary neutron star systems in the last milliseconds before and after their merger. In such systems gravity is strong and has to be described by Einstein’s full Theory of General Relativity. Because of the complexity of the governing equations of general relativity and relativistic hydrodynamics no analytical solutions exist. Thus, the usage of numerical methods is inevitable. Throughout the thesis we consider different configurations by varying the spin, the equation of state, and the mass-ratio. In particular, we present the first consistent, constraint solved simulations of spinning binary neutron stars in full general relativity and the highest mass ratios simulated to date. Additionally, new numerical methods were implemented in the existing BAM code, most notably a refluxing algorithm which ensures mass conservation across mesh refinement boundaries. This algorithm allowed us to perform the most accurate simulations of the gravitational collapse of a rotating neutron star. In addition to pure numerical waveform modeling, we used high-resolution simulations to validate an improved tidal effective-one-body model and show that the new formalism can predict the waveform accurately up to the moment of merger. Furthermore, the effective-one-body model predicts quasi-universal relations, which we found also in full general relativistic simulations for the inspiral and even in the postmerger phase.'] | ['gnd:1104751291', 'gnd:36164-1', 'gnd:4158119-2', 'gnd:4171660-7', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A852169647'] | ['Dietrich, Tim', 'Friedrich-Schiller-Universität Jena', 'Gravitationswelle', 'Neutronenstern'] | 22 | 13,566 |

One major biotic stress factor is the attack of herbivorous insects feeding on the plant. During the feeding process wounding of plant tissue and contact with elicitors in insect’s oral secretion (OS) occurs. The early events upon perception of these stimuli are still poorly understood. Elevations in cytosolic calcium are one of these early events, which activate the downstream signaling network. To reach this a proper decoding of calcium signals is important. In this study it was demonstrated that in Arabidopsis thaliana, several members of the calmodulin-like proteins (CMLs), one group of calcium sensors, are induced upon OS of the generalist herbivore Spodoptera littoralis. In herbivory, CML37 is strongly upregulated upon mechanical wounding, but responds additionally to elicitors in OS. Upon stress stimuli, CML37 binds to cytosolic free calcium and undergoes conformational changes. Mutation of CML37 increases plants susceptibility to herbivore feeding indicating that CML37 acts as a positive defense regulator. Beside herbivore defense, CML37 is also involved in ABA signaling during drought stress where mutation of CML37 results in drastically reduced survival of plants. Plant defense is a complex network of different pathways. Next to the jasmonate pathway, also the accumulation of γ-amino butyric acid (GABA) is calcium-mediated. Upon elevation of cytosolic calcium and binding by calmodulin (CaM), the glutamate decarboxylases (GADs) are activated and GABA produced. It was demonstrated that GABA is accumulated upon wounding of plant tissue and Spodoptera littoralis feeding. Higher level of GABA in a mutant or in artificial diet significantly reduced growth of Spodoptera littoralis larvae showing that herbivore-induced accumulation of GABA is a wound-induced, JA-independent and systemic plant defense.'] | ['gnd:1096474700', 'gnd:36164-1', 'gnd:4141299-0', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A852694369'] | ['Scholz, Sandra', 'Friedrich-Schiller-Universität Jena', 'Ackerschmalwand'] | 3 | 13,567 |

The diffraction limit states that it is not possible to create an image of an object with a resolution smaller than half the wavelength. The basal reason for this effect is the loss of information when light is emitted or scattered by an object and reconstructed by a classical optical system. There are already many ways to obtain images with subwavelength resolution, for example by measuring the near field of an object, or by adding information regarding, for instance, the location (STED).In this work, however, is not about measuring methods, but fundamentally the interaction of light with matter. Therefore, a terahertz near-field microscope is used which is able to measure electric field distributions with a resolution far below the diffraction limit.First, the diffraction-limited focusing of light in free space is investigated. These results are used to determine the Gouy phase of strongly focused, linearly and radially polarised terahertz radiation. Hereby, not only the transverse, but also the longitudinal component are investigated. Subsequently, two material systems are introduced which allow for focusing light below the diffraction limit and to generate images whose resolution are far below the diffraction limit.The first system is a plasmonic lens. It consists of a circular electrically conductive disc, along the edge of which surface plasmon polaritons (SPPs) are excited, when illuminated with radially polarised radiation. These SPPs propagate in phase towards the centre of the disc and interfere constructively so that a maximum is generated at the centre. This maximum, described by a Bessel function of the 0th order is independent of any numerical aperture, thus allowing the focusing below the diffraction limit. By adding rings around the central disc, with a spacing corresponding to the circular Bragg condition, the intensity of certain frequencies can be increased.The second system is a metamaterial, which is referred to as wire medium. It consists of an array of very narrow metal wires that are embedded in a host. Such a structure exhibits a strong optical anisotropy. Therefore, it has very interesting optical properties that allow to convert evanescent waves into propagating waves, to transport and reconstruct them on the image plane of the wire medium', 'Zusammenfassung: Diese Arbeit behandelt das Beugungslimit von Licht und untersucht theoretische als auch experimentelle Möglichkeiten dieses zu überwinden. Das Beugungslimit besagt, dass es mit Licht nicht möglich ist Details eines Objekts, das abgebildet werden soll, aufzulösen, die kleiner als die halbe Wellenlänge sind. Der basale Grund für diesen Effekt ist der Verlust von Informationen, wenn Licht von einem Objekt ausgesendet oder gestreut wird und mit Hilfe eines optischen Systems zu einem Abbild wieder zusammengefügt wird. Es existieren heute schon viele Möglichkeiten diesem Verlust entgegenzuwirken, indem man z.B. das Nahfeld vermisst, das Informationen von evaneszenten Wellen trägt, oder zusätzliche Informationen bezüglich des Ortes durch die Messtechnik hinzufügt, die es erlauben die Anregung sehr genau zu lokalisieren (STED). In dieser Arbeit geht es jedoch nicht um Messverfahren, sondern grundlegend um die Interaktion von Licht mit Materie. Dazu wird ein Terahertz Nahfeld-Mikroskop verwendet, das in der Lage ist elektrische Feldverteilungen mit einer Auflösung weit unterhalb des Beugungslimits zu vermessen.Zunächst wird die beugungslimitierte Fokussierung von Licht im freien Raum untersucht. Diese Ergebnisse werden benutzt um die Gouy-Phase stark fokussierter, linear und radial polarisierter Terahertzstrahlung zu bestimmen. Anschließend werden zwei Materialsysteme vorgestellt, die es erlauben Licht unter das Beugungslimit zu fokussieren und Abbildungen zu erzeugen, deren Auflösung weit unterhalb des Beugungslimits liegen.Das erste System ist eine plasmonische Linse. Sie besteht aus einer kreisförmigen, elektrisch leitenden Scheibe, entlang deren Rand Oberflächenplasmonen angeregt werden, wenn sie mit radial polarisierter Strahlung beleuchtet wird. Diese laufen in Phase in Richtung der Mitte der Scheibe und interferieren konstruktive, so dass ein Maximum im Zentrum erzeugt wird. Dieses Maximum, beschrieben durch eine Bessel-Funktion 0.

Bringt man nun zusätzlich mehrere Ringe um die Scheibe an, der Abstand der zirkularen Bragg-Bedingung entsprechen, kann die Intensität für bestimmte Frequenzen erhöht werden.Das zweite System ist ein Metamaterial, welches als Wire Medium bezeichnet wird.

Both aspects are analyzed in two separate empirical studies, respectively. The analyses are based on two unique data sets: a hand-collected data set on the biographical background of board members and confidential payroll data for non-executive bank employees provided by an international consulting company. The results indicate that both aspects of corporate governance matter. Higher executive team expertise is associated with superior bank outcomes regarding performance, risk and efficiency. Compensation analyses show strong variation in compensation schemes between banks and bank divisions. Moreover, the results indicate that strong incentives in capital market divisions induced excessively high risks in the capital market segments in the run up to the crisis, while this nexus cannot be observed for more moderate bonus schemes in the crisis period.', 'Das internationale Bankensystem stand in den vergangenen Jahren im Fokus des öffentlichen Interesses.

Given a large increase in the migrant population of many developed countries in recent decades, it is important to know both how migrants integrate into the destination countries and how immigration affects natives. Beside the motivation of the topic, the introduction in Chapter 1 of the volume summarizes three studies of the author that deal with explanations for migrant selection and the importance of migrant selection to labor force quality. Chapter 2 quantifies non-pecuniary migration costs that are incurred due to selective migration along cultural traits. Chapter 3 discusses whether early performance-based tracking of children into different school types impede migrant integration. Chapters 4 and 5 cover the effect of immigration on the host societies by showing that growing up in high immigration area increases intergenerational income mobility among natives and by showing that immigration may, under specific circumstances, increase crime.', 'Die vorliegende Arbeit wurde von Jens Ruhose während seiner Tätigkeit am ifo Institut erstellt.

Over the last centuries, the BGB has been intensively studied at surface with detailed mapping of its surfacial geological units and tectonic features. Nevertheless, the deeper structure of the BGB remains poorly understood. Various tectonic evolution models have been developed based on geo-chronological and structural data. These theories are highly controversial and centre on the question whether plate tectonics - as geoscientists understand them today - was already evolving on the Early Earth or whether vertical mass movements driven by the higher temperature of the Earth in Archean times governed continent development. To get a step closer to answering the questions regarding the internal structure and formation of the BGB, magnetotelluric (MT) field experiments were conducted as part of the German-South African research initiative Inkaba yeAfrica. Five-component MT data (three magnetic and two electric channels) were collected at ~200 sites aligned along six profiles crossing the southern part of the BGB. Tectonic features like (fossil) faults and shear zones are often mineralized and therefore can have high electrical conductivities. Hence, by obtaining an image of the conductivity distribution of the subsurface from MT measurements can provide useful information on tectonic processes. Unfortunately, the BGB MT data set is heavily affected by man-made electromagnetic noise caused, e.g. by powerlines and electric fences. Aperiodic spikes in the magnetic and corresponding offsets in the electric field components impair the data quality particularly at periods >1 s which are required to image deep electrical structures. Application of common methods for noise reduction like delay filtering and remote reference processing, only worked well for periods <1 s. Within the framework of this thesis two new filtering approaches were developed to handle the severe noise in long period data and obtain reliable processing results. The first algorithm is based on the Wiener filter in combination with a spike detection algorithm. Comparison of data variances of a local site with those of a reference site allows the identification of disturbed time series windows for each recorded channel at the local site. Using the data of the reference site, a Wiener filter algorithm is applied to predict physically meaningful data to replace the disturbed windows. While spikes in the magnetic channels are easily recognized and replaced, steps in the electric channels are more difficult to detect depending on their offset. Therefore, I have implemented a novel approach based on time series differentiation, noise removal and subsequent integration to overcome this obstacle. A second filtering approach where spikes and steps in the time series are identified using a comparison of the short and long time average of the data was also implemented as part of my thesis. For this filtering approach the noise in the form of spikes and offsets in the data is treated by an interpolation of the affected data samples. The new developments resulted in a substantial data improvement and allowed to gain one to two decades of data (up to 10 or 100 s). The re-processed MT data were used to image the electrical conductivity distribution of the BGB by 2D and 3D inversion. Inversion models are in good agreement with the surface geology delineating the highly resistive rocks of the BGB from surrounding more conductive geological units. Fault zones appear as conductive structures and can be traced to depths of 5 to 10 km. 2D models suggest a continuation of the faults further south across the boundary of the BGB. Based on the shallow tectonic structures (fault system) within the BGB compared to deeply rooted resistive batholiths in the area, tectonic models including both vertical mass transport and in parts present-day style plate tectonics seem to be most likely for the evolution of the BGB.'] | ['gnd:1049859308', 'gnd:1098339185', 'gnd:123626242', 'gnd:2120681-8', 'gnd:4078012-0', 'gnd:4168603-2', 'gnd:4278975-8', 'gnd:4589361-5', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A857543946'] | ['Weber, Michael', 'Kütter, Sissy', 'Weckmann, Ute', 'Universität Potsdam', 'Südafrika', 'Magnetotellurik', 'Archaikum (Geologie)', 'Barberton Greenstone Belt'] | 8 | 13,572 |

Transition from one process to the next is guided by a number of crucial surveillance mechanisms, the so called cell cycle checkpoints. Dis-regulation of the cell cycle through checkpoint malfunction can lead to developmental defects and contribute to the development or progression of tumors. The cell cycle checkpoints are complex biochemical signal transduction networks, and their elaborate spatiotemporal dynamics are challenging to understand intuitively. Mathematical modeling and computer simulation can help to decrypt the underlying principles. This thesis approaches two important mitotic checkpoints with mathematical modeling and simulation. The highly conserved spindle assembly checkpoint (SAC) guards the transition from meta- to anaphase, preventing premature chromosome segregation to the spindle poles. In contrast to SAC, the spindle position checkpoint (SPOC) ensures that during asymmetric cell division in budding yeast mitotic exit does not occur until the spindle is properly aligned with the cell polarity axis. Although there are no known homologs, there is indication that functionally similar checkpoints exist also in animal cells. First, a detailed analysis of the kinetic consequences of localization of SAC key components to the kinetochores is presented. Second, a truly minimal, though physically meaningful kinetic model of the small Ras-linke GTPase Tem1 is established to develop the first detailed model of the SPOC. Both analyses provide valuable insights into mitotic transition control on a systems level and demonstrate that mathematical modeling, despite all unavoidable abstraction, constitutes a powerful tool for investigation of the dynamic properties of complex biological systems.'] | ['gnd:1098348990', 'gnd:36164-1', 'gnd:4129960-7', 'gnd:4153142-5', 'gnd:4611085-9', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A862172306'] | ['Lohel, Maiko', 'Friedrich-Schiller-Universität Jena', 'Zellzyklus', 'Eukaryontische Zelle', 'Bioinformatik'] | 3 | 13,575 |

This dissertation aims to understand the ‘what’ of decision making by connecting two fields of research that have up to now been studied independently and in isolation: Intuitive/Deliberative Decisions and Dual-Motive Theory. The dual-motive theory proposes two kinds of underlying motivational sources: Implicit and Explicit Motives. While implicit motives are non-declarative, affective-based and partially an innate-system, explicit motives are declarative, cognitively elaborate and a socially-influenced system. This dissertation proposes that intuitive decisions are driven by implicit motives while deliberative decisions are driven by explicit motives. These two hypotheses were tested empirically across five experiments. Throughout the experiments, intuitive and deliberative decision modes were induced via instructions. Decisions were in the form of scenarios with options corresponding to Achievement, Affiliation or Power motives. Contrary to our hypothesis, we did not find differences depending on the decision mode. Regardless of whether decisions were made intuitively or deliberatively, explicit motives predicted decisions and implicit motives did not predict decisions. The fact that implicit motives did not predict decisions could mean that (a) it is not implicit motives that drive intuitive decisions or (b) it was not intuition which was assessed. Further examinations on implicit motive and decision making literature revealed that (a) while the influence of implicit motives has been shown in a variety of cognitive and behavioural indicators, the exact processes of how motives affect behaviors have not been properly addressed and (b) while the basic distinction between intuitive and deliberative may be clear, it remains unclear when exactly each mode of decision making becomes activated.'] | ['gnd:1109906706', 'gnd:36164-1', 'gnd:4014904-3', 'gnd:4075001-2', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A866898077'] | ['Okvitawanli, Ayu', 'Friedrich-Schiller-Universität Jena', 'Entscheidung', 'Motivationspsychologie'] | 20 | 13,577 |

Currently, the enthusiasm for this approach outweighs the evidence supporting its application. In this dissertation I present a) a meta-analytic review of the existing evidence and b) further empirical data regarding the efficacy of mindfulness-based school programs, also considering the me- thodological quality of evaluation studies in this nascent field. Methods: a) In order to locate both published and unpublished studies a comprehensive search strategy was applied. Data on methodology and outcomes of included studies were extracted. Effect sizes were combined using the random-effect model. b) In two pilot stu- dies, effects of a mindfulness-based school program on measures of attention, self- regulation, empathy, mental health and well-being were examined in a controlled pre-post design. In study I, n = 20 fourth grade students took part in a 6 week-mindfulness pro- gram; in study II, n = 25 second grade students participated in a modified version of the mindfulness program (20 weeks). Parallel classes served as the control. Results: a) Twenty-four studies were located, of which eleven were unpublished. Nineteen studies used a controlled design. Altogether, 1,348 students were instructed in mindful- ness, with 863 serving as comparison groups, ranging from school grades 1 to 12. Overall effect sizes were g = 0.41 within groups and g = 0.40 between groups. Domain specific, controlled, effect sizes varied from g = 0.80 for measures of cognitive performance to g = 0.19 for measures of emotional problems. However, heterogeneity was significant and could partly be explained by the intensity of mindfulness programs. b) In study I, interac- tion effects (time x group) occurred in three subscales of teacher ratings on mental health (hyperactivity/inattention, peer relationship problems, prosocial behaviour), indicating the superiority of the control (all p ≤ .05). In study II, interaction effects (time x group) occur- red in one subscale of teacher questionnaires in mental health (conduct problems, p ≤ .01) and in two subscales of after-school-care teachers (peer relationship problems, prosocial behaviour (both p ≤ .05)), reflecting improvement in the mindfulness class. In general, the feasibility of this evaluation can be confirmed, but the adequacy of some measures being applied in this field of research need to be adressed. Conclusion: Preliminary evidence supports the efficacy of mindfulness programs, but replication in rigorous research designs is required. Future research should consider the special features of students and the school setting.…', 'Einleitung: Obwohl Achtsamkeitsprogramme für den Bildungsbereich zunehmend an Popularität gewinnen, ist die empirische Basis für deren Anwendung noch unzureichend. In dieser Dissertation stelle ich a) einen metaanalytischen Review über den aktuellen For-schungsstand und b) selbsterhobene empirische Daten bezüglich der Wirksamkeit acht-samkeitsbasierter Interventionen im Schulkontext, unter der Berücksichtigung der metho-dischen Güte von Evaluationsstudien in diesem neuen Forschungsfeld, vor. Methode: a) Um auch nicht-publizierte Studien ausfindig machen zu können, wurde eine weitläufige Suchstrategie gewählt. Informationen zur Studienqualität sowie quantitative Daten wurden extrahiert und Effektstärken auf Basis des Modells zufallsvariabler Effekte ermittelt. b) In 2 Pilotstudien wurde die Wirksamkeit eines Achtsamkeitsprogramms in Bezug auf spezifische Aufmerksamkeitsfähigkeiten, die Selbstregulationsfähigkeit, die Empathiefähigkeit, psychische Gesundheit und das Wohlbefinden in einem kontrollierten Prä-post-Design untersucht. In Studie I nahm eine 4. Klasse (n = 20) an einem sechswö-chigen Achtsamkeitsprogramm teil, während in Studie II eine 2. Klasse (n = 25) an einer modifizierten Version des Programms (20 Wochen) teilnahm. Die jeweilige Parallelklasse fungierte als Kontrollgruppe. Ergebnisse: a) 24 Studien konnten ausfindig gemacht werden, von denen 11 nicht publi-ziert sind. Größtenteils wurden kontrollierte Designs (k = 19) verwendet. Von Klasse 1 bis Klasse 12 nahmen insgesamt 1348 Schülerinnen und Schüler an einem Achtsamkeits-training teil und 871 fungierten als Kontrollgruppe. Die globalen Effekte beliefen sich auf g = 0.40 für kontrollierte und g = .41 für Prä-post-Effektgrößen. Domänenspezifische, kontrollierte Effektgrößen variierten zwischen g = 0.80 für Maße der kognitiven Perfor-manz und g = 0.19 für emotionale Probleme. Jedoch war die Varianz der Studieneffekte überzufällig groß. Sie konnte zum Teil durch die unterschiedliche Intensität der Pro-gramme aufgeklärt werden. b) In Studie I ergaben sich hypothesenkonträre Interaktionsef-fekte (Zeit x Gruppe) für drei Subskalen eines Lehrkräftefragebogens (Hyperaktivi-tät/Unaufmerksamkeit, Probleme mit Gleichaltrigen, prosoziales Verhalten, alle p ≤ .05). In Studie II zeigten sich hypothesenkonforme Interaktionseffekte (Zeit x Gruppe) für die von den Klassenlehrerinnen eingeschätzte Subskala Verhaltensprobleme (p ≤ .01) sowie für die von den Horterzieherinnen eingeschätzten Subskalen Probleme mit Gleichaltrigen und Prosoziales Verhalten (beide p ≤ .05). In Bezug auf spezifische Aufmerksamkeitsfä-higkeiten, die Selbstregulationsfähigkeit, die Empathiefähigkeit, das Wohlbefinden und den Gesamtwert für psychischen Auffälligkeiten waren keine Interaktionseffekte festzu-stellen. Die Evaluation ist grundsätzlich als durchführbar einzustufen, allerdings ist die Adäquatheit einiger der üblicherweise verwendeten Messinstrumente infrage zu stellen. Fazit: Die vorläufigen Belege für die Wirksamkeit von Achtsamkeitsprogrammen im Schulkontext erfordern Replikationen in methodisch hochwertigeren Untersuchungen. Bei der Methodenwahl sollten die Besonderheiten der Zielgruppe der Schülerinnen und Schüler sowie des Settings Schule stärker beachtet und für die Umsetzung innovativer Forschungsmethoden genutzt werden.…']] | ['gnd:135912911', 'gnd:4053474-1', 'gnd:4162156-6', 'gnd:4297929-8', 'gnd:5059953-7', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A870990810'] | ['Walach, Harald', 'Schule', 'Intervention', 'Achtsamkeit', 'Europa-Universität Viadrina Frankfurt (Oder)'] | 20 | 13,582 |

One of the cardinal predictions of this theory are black holes. Massive, dark objects are found in the majority of galaxies. Our own galactic center very contains such an object with a mass of about four million solar masses. Are these objects supermassive black holes (SMBHs), or do we need alternatives? The answer lies in the event horizon, the characteristic that defines a black hole. The key to probe the horizon is to model the movement of stars around a SMBH, and the interactions between them, and look for deviations from real observations. Nuclear star clusters harboring a massive, dark object with a mass of up to ~ ten million solar masses are good testbeds to probe the event horizon of the potential SMBH with stars. The channel for interactions between stars and the central MBH are the fact that (a) compact stars and stellar-mass black holes can gradually inspiral into the SMBH due to the emission of gravitational radiation, which is known as an “Extreme Mass Ratio Inspiral” (EMRI), and (b) stars can produce gases which will be accreted by the SMBH through normal stellar evolution, or by collisions and disruptions brought about by the strong central tidal field. Such processes can contribute significantly to the mass of the SMBH. These two processes involve different disciplines, which combined will provide us with detailed information about the fabric of space and time.

However, contrasting results have been observed for the mobility of different nanoparticle transport in porous media coated with biofilms. Also, no comparative studies ave been done linking the effect of biofilms on colloidal stability and mobility of colloids to date. Laboratory scale experiments were conducted to obtain insights into different ways bacterial biofilms and EPS can influence the transport of nanoparticles in porous media. Using complementary experimental approaches, we investigated (1) the effect of microbial EPS on the colloidal stability of nanoparticles, (2a.) the transport of uncoated colloidal nanoparticles in biofilm and EPS-coated porous media, (2b.) the transport of EPS-coated colloidal nanoparticles in uncoated porous media (2c), the combined transport of EPS-coated colloids in biofilm and EPS-coated porous media, and finally (3) the remobilization of deposited colloidal nanoparticles by EPS. Laboratory synthesized hematite nanoparticles (HNP) and Bacillus subtilis 168 (DSM 402) were used as nanoparticles and biofilm forming bacterium respectively. To study the effect of EPS on the colloidal stability, HNP were amended with three increasing concentrations of EPS (20, 200 and 500 mg/l carbon) resulting in carbon:iron ratios 1:5, 2:1 and 5:1, respectively. The zeta potential (ZP), the shift in isoelectric point and the change in the critical coagulation concentration (CCC) for NaCl and CaCl2 showed formation of colloidally stable organo-mineral colloids at higher concentrations of EPS (200 mg/l and 500 mg/l of carbon, HNP2:1, HNP 5:1). However, lower concentrations of EPS (20 mg/l carbon, HNP 1:5) resulted into aggregation of HNP. The transport of uncoated and EPS-coated HNP colloids at environmental pH was studied with closed flow columns experiments in three different synthetic porous media, i.e., uncoated, biofilm-coated, and EPS-coated glass beads. No drastic change was observed in the pH and the electrical conductivity of the system during the transport experiments. However, a constant amount of organic matter and bacterial cells were continuously released from the porous media coatings. In the first scenario, positively charged uncoated HNP were immobile and retained in uncoated-glass bead porous media. Contrary, a mobile fraction of negatively charged HNP was observed in biofilms and EPS-coated porous media. The charge reversal of HNP during transport is due to adsorption of organic matter released from the coatings forming organomineral associations of HNP and components of the biofilm or EPS.'] | ['gnd:1123963029', 'gnd:36164-1', 'gnd:4004296-0', 'gnd:4164695-2', 'gnd:4232790-8', 'gnd:4443397-9', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A877609373'] | ['Narvekar, Sneha Pradip', 'Friedrich-Schiller-Universität Jena', 'Bakterien', 'Kolloid', 'Biofilm', 'Stofftransport (Biologie)'] | 3 | 13,593 |

Nanoparticles (NPs) can nowadays easily be synthesized from different material compositions by different chemical and physical processes. However, most of these techniques work close to or at the thermal equilibrium. One subsequent approach to tune materials beyond equilibrium conditions is ion beam irradiation. An important effect of this approach is sputtering. Sputtering is enhanced in NPs compared to their bulk counterparts due to their large surface-to-volume ratio, especially when the ion range matches the NP size. In this work, the sputtering effects of Ar+ and Ga+ ion irradiated Au nanoparticles are investigated in detail by Monte Carlo (MC) and molecular dynamics (MD) simulations and a variety of experiments. The sputtering of Ar+ and Ga+ irradiated Au NPs was investigated as a function of ion energy, NP size and impact parameter by the MC code iradina and MD code parcas. The simulation results are directly compared to experiments using high resolution scanning electron microscopy (SEM) of Au NPs on top of Si, whereat the sputter yields are significantly enhanced compared to the MC simulations. Additionally, the interaction of NPs and substrate were investigated by Rutherford backscatter spectrometry (RBS), atomic force microscopy (AFM) and scanning transmission electron microscopy (STEM). A new MC code was developed to study the redeposition of sputtered atoms of Ga+ irradiated Au NP arrays on neighboring NPs. The redeposition can lead to growth of NPs with diameters of 1 nm in vicinity of ~50 nm NP. These simulations are directly compared to an in situ experiment. Nanostructures, spherical NPs as well as nanowires (NWs) are used as irradiation masks to structure lithium niobate (LNO) using the ion beam enhanced etching (IBEE) technique. The aspect ratio of the obtained structures can be enhanced by a second IBEE step after annealing.'] | ['gnd:1122115717', 'gnd:36164-1', 'gnd:4027606-5', 'gnd:4342626-8', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A877739455'] | ['Holland-Moritz, Henry', 'Friedrich-Schiller-Universität Jena', 'Ionenimplantation', 'Nanostrukturiertes Material'] | 22 | 13,594 |

Though these projects become increasingly complex, the demands on financial efficiency and the completion within a tight schedule grow at the same time. The digital collaboration of project partners has been identified as one key issue in successfully dealing with these challenges. Yet currently, the numerous software applications and their respective individual views on the design process severely impede that collaboration. An approach to establish a unified basis for the digital collaboration, regardless of the existing software heterogeneity, is a comprehensive digital building model contributed to by all projects partners. This type of data management known as building information modeling (BIM) has many benefits, yet its adoption is associated with many difficulties and thus, proceeds only slowly. One aspect in the field of conflicting requirements on such a digital model is the cooperation of architects and structural engineers. Traditionally, these two disciplines use different abstractions of reality for their models that in consequence lead to incompatible digital representations thereof. The onset of isogeometric analysis (IGA) promised to ease the discrepancy in design and analysis model representations. Yet, that initial focus quickly shifted towards using these methods as a more powerful basis for numerical simulations. Furthermore, the isogeometric representation alone is not capable of solving the model abstraction problem. It is thus the intention of this work to contribute to an improved digital collaboration of architects and engineers by exploring an integrated analysis approach on the basis of an unified digital model and solid geometry expressed by splines. In the course of this work, an analysis framework is developed that utilizes such models to automatically conduct numerical simulations commonly required in construction projects. In essence, this allows to retrieve structural analysis results from BIM models in a fast and simple manner, thereby facilitating rapid design iterations and profound design feedback. The BIM implementation Industry Foundation Classes (IFC) is reviewed with regard to its capabilities of representing the unified model. The current IFC schema strongly supports the use of redundant model data, a major pitfall in digital collaboration. Additionally, it does not allow to describe the geometry by volumetric splines. As the pursued approach builds upon a unique model for both, architectural and structural design, and furthermore requires solid geometry, necessary schema modifications are suggested. Structural entities are modeled by volumetric NURBS patches, each of which constitutes an individual subdomain that, with regard to the analysis, is incompatible with the remaining full model. The resulting consequences for numerical simulation are elaborated in this work. The individual subdomains have to be weakly coupled, for which the mortar method is used. Different approaches to discretize the interface traction fields are implemented and their respective impact on the analysis results is evaluated. All necessary coupling conditions are automatically derived from the related geometry model. The weak coupling procedure leads to a linear system of equations in saddle point form, which, owed to the volumetric modeling, is large in size and, the associated coefficient matrix has, due to the use of higher degree basis functions, a high bandwidth. The peculiarities of the system require adapted solution methods that generally cause higher numerical costs than the standard procedures for symmetric, positive-definite systems do. Different methods to solve the specific system are investigated and an efficient parallel algorithm is finally proposed. When the structural analysis model is derived from the unified model in the BIM data, it does in general initially not meet the requirements on the discretization that are necessary to obtain sufficiently accurate analysis results. The consequently necessary patch refinements must be controlled automatically to allowfor an entirely automatic analysis procedure. For that purpose, an empirical refinement scheme based on the geometrical and possibly mechanical properties of the specific entities is proposed. The level of refinement may be selectively manipulated by the structural engineer in charge. Furthermore, a Zienkiewicz-Zhu type error estimator is adapted for the use with isogeometric analysis results. It is shown that also this estimator can be used to steer an adaptive refinement procedure.'] | ['gnd:1030375127', 'gnd:103573382X', 'gnd:1124633405', 'gnd:131937685', 'gnd:4060592-9', 'gnd:4376916-0', 'gnd:7718401-4', 'gnd:7861550-1', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A87876092X'] | ['Beucke, Karl', 'Könke, Carsten', 'Schwedler, Michael', 'Rank, Ernst', 'Tragwerk', 'NURBS', 'Isogeometrische Analyse', 'Building Information Modeling'] | 22 | 13,595 |

Each child got the task to solve a puzzle half with the mother and the other with the father within 15 minutes. Parent-child interactions of 15 families with one child with a cleft lip and palate were recorded and compared with the parent-child interactions of 20 families with one child with migraine. In order to investigate possible behavioral problems and particular personality traits, the children of both groups had to complete four questionnaires on specific disorder areas in the child's age. The study suggests that children with a cleft lip and palate, unlike children with migraine, are better able to deal with their impairment than previously thought. Within the families with a child with a cleft lip and palate, difficulties in the disease are not so much in the foreground, perhaps even become more trivialized than in families with a child with migraine. The type of parent-child interaction in families with a child with a cleft lip and palate can be associated with the disease processing of the parents, even for individually different reasons, and represent a kind of psychosocial compensation of the children with an cleft lip and palate in the family environment.", 'Patienten mit einer Lippen-Kiefer-Gaumenspalte (LKGS) werden aufgrund ihrer Fehlbildung und den damit einhergehenden funktionellen und ästhetischen Beeinträchtigungen von Geburt an mit vielfältigen Belastungen konfrontiert. Das Ziel dieser Studie war daher, Familien mit einem Kind mit LKGS exemplarisch mit Familien mit einem Kind mit Migräne bezüglich der Zusammenhänge zwischen besonderen Merkmalen der Familieninteraktion einerseits und Verhaltensauffälligkeiten und besonderen Persönlichkeitsmerkmalen der Kinder andererseits zu vergleichen. Zur Untersuchung des Interaktionsverhaltens in Familien mit einem Kind mit LKGS wurden die Kinder mit einer leistungsorientierten Aufgabenstellung in Form eines Puzzlespiels konfrontiert. Jedes Kind bekam die Aufgabe, eine Puzzlehälfte mit der Mutter und die andere mit dem Vater innerhalb von jeweils 15 Minuten zu lösen. Die Eltern-Kind-Interaktionen von 15 Familien mit einem Kind mit LKGS wurden mittels einer mit einem Mikrophon ausgestatteten Videokamera aufgezeichnet und mit den Eltern-Kind-Interaktionen von 20 Familien mit einem Kind mit Migräne verglichen. Zur Untersuchung möglicher Verhaltensauffälligkeiten und besonderer Persönlichkeitsmerkmale mussten die Kinder beider Gruppen jeweils vier Fragebögen zu bestimmten Störungsbereichen im Kindesalter ausfüllen. Die Untersuchung deutet darauf hin, dass Kinder mit einer LKGS, im Unterschied zu Kindern mit Migräne, besser mit ihrer Beeinträchtigung umgehen können als bisher angenommen wurde. Innerhalb der Familien mit einem Kind mit LKGS stehen Schwierigkeiten im Zusammenhang mit der Erkrankung nicht so sehr im Vordergrund, werden vielleicht sogar stärker bagatellisiert, als in Familien mit einem Kind mit Migräne. Die Art der Eltern-Kind-Interaktion in Familien mit einem Kind mit LKGS kann durchaus, wenn auch aus individuell unterschiedlichen Gründen, mit der Krankheitsverarbeitung der Eltern in Verbindung gebracht werden und eine Art psychosoziale Kompensation der Kinder mit einer LKGS im familiären Umfeld darstellen.']] | ['gnd:132595516', 'gnd:2024175-6', 'gnd:4014516-5', 'gnd:4030550-8', 'gnd:4039179-6', 'gnd:4062872-3', 'gnd:4066880-0', 'gnd:4075995-7', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A88026229X'] | ['Gaßling, Volker Leonhard Wilhelm', 'Christian-Albrechts-Universität zu Kiel', 'Eltern', 'Kind', 'Migräne', 'Verhaltensstörung', 'Lippen-Kiefer-Gaumenspalte', 'Persönlichkeitsentwicklung'] | 18 | 13,598 |

With this objective, three dimensional environments for human cells were developed and tested using three different types of hydrogels including transglutaminase-crosslinked gelatin, collagen type I and growth-factor depleted Matrigel. Cells grown in Matrigel exhibited the greatest cell proliferation and spheroid diameter. Moreover, urea and albumin analysis indicated that the created system allows the immortalized liver cell line (HepG2) to re-establish normal hepatocyte-like properties which are not observed under the conditions of conventional cell cultures. This study presents a reproducible technology for production of complex-shaped liver multicellular spheroids as a system which improves the predictive value of cell-based assays for safety and risk assessment. The time- and dose-dependent toxicity of nanoparticles demonstrates higher cytotoxic effects when HepG2 cells grown as monolayer than embedded in hydrogels. The experimental setup provided evidence that cell environment has significant influence on cell sensitivity and that liver spheroids are useful and novel tools to examine NP dosing effect even at the level of in vitro studies. Moreover, the created cell-based biosensor responds optimally to bioactive analytes, has a fast response time, offers label-free experimentation and simple procedures. Besides, the developed NF-κB_HepG2 cells enable detect cytotoxicity of variety nanoparticles with different chemical composition, size, tendency of agglomeration or cytotoxic potential and other stimuli which activate NF-κB signaling (e.g. heavy metals), in very early stage, before cell death, in short time even after 2 h time exposure as opposed to widely used commercially available cell-based assays like MTT, XTT Alamar Blue or LDH. Successful modification of HepG2 cells resulted in generation of novel NF-κB_HepG2 sensor cells with extracellular reporter protein (human secreted alkaline phosphatase) and its application in cytotoxicity of nanomaterials detection has not been investigated before. The developed NF-κB_hepG2 cells may also provide a useful tool to study distinct molecular mechanisms of inflammation and cellular stress using low exposure concentrations of cell irritants. The presented sensor based on human cells in three dimensional milieu provides a novel application for nanoparticles screening that joins the complex in vitro model imitating living tissue with high throughput analytical methods. This system can be applied to a wide diversity of potentially hostile compounds in basic screening to provide initial warning of adverse effects and trigger subsequent analysis and remedial actions.'] | ['gnd:1125395524', 'gnd:36164-1', 'gnd:4067547-6', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A880304294'] | ['Dubiak-Szepietowska, Monika', 'Friedrich-Schiller-Universität Jena', 'Zellkultur'] | 3 | 13,601 |

The fourth chapter will combine three different examples regarding linear, star-shaped and hybrid polymers, which were analyzed by advanced techniques. The linear copolymers were analyzed by separating them according to their chemical heterogeneity using liquid absorption chromatography at critical conditions (LACCC) of poly(2-ethyl-2-oxazoline) (PEtOx), followed by automated spotting onto a MALDI target, which was subsequently analyzed by MALDI. Secondly, star-shaped polymers: [poly(ethylene oxide) (PEO)-b-PEtOx]8 were monitored firstly by using LACCC of linear PEO as first separation dimension and furthermore injected onto an SEC column confirming the molar mass. Lastly, a hybrid PEO star-shaped polymer was investigated using MALDI to verify the complete functionality of the core with PEO arms. Finally, the last chapter will focus on the creation of a software to obtain information regarding average composition, overcoming isotopic, overlapping peaks and isobaric species from MS spectra. Moreover, the quantitative studies were carried out by correction of the mass discrimination and isotopic abundance. Consequently, advanced analytical techniques such as different ionization techniques within MS, a range of chromatographic hyphenation and computational methods are implemented for elucidating the complexity of synthetic polymers.'] | ['gnd:1124709509', 'gnd:36164-1', 'gnd:4009840-0', 'gnd:4046699-1', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A880851295'] | ['Crotty, Sarah Charlotte', 'Friedrich-Schiller-Universität Jena', 'Chemische Analyse', 'Polymere'] | 5 | 13,602 |

The derived flow equations are solved via pseudo-spectral methods. As they allow to resolve the full field dependence of the effective potential and provide highly accurate results, these numerical methods are very powerful but have hardly been used in the FRG context. We show their benefits using several examples. Moreover, we apply the pseudo-spectral methods to explore the phase diagram of a bosonic model with two coupled order parameters and to clarify the nature of a possible metastability of the Higgs-Yukawa potential.In the phase diagram of systems with two competing order parameters, fixed points govern multicritical behavior. Such systems are often discussed in the context of condensed matter. Considering the phase diagram of the bosonic model between two and three dimensions, we discover additional fixed points besides the well-known ones from studies in three dimensions. Interestingly, our findings suggest that in certain regions of the phase diagram, two universality classes coexist. To our knowledge, this is the first bosonic model where coexisting (multi-)criticalities are found. Also, the absence of nontrivial fixed points can have a physical meaning, such as in the electroweak sector of the standard model which suffers from the triviality problem. The electroweak transition giving rise to the Higgs mechanism is dominated by the Gaussian fixed point. Due to the low Higgs mass, perturbative calculations suggest a metastable potential. However, the existence of the lower Higgs-mass bound eventually is interrelated with the maximal ultraviolet extension of the standard model. A relaxation of the lower bound would mean that the standard model may be still valid to even higher scales. Within a simple Higgs-Yukawa model, we discuss the origin of metastabilities and mechanisms, which relax the Higgs-mass bound, including higher field operators.'] | ['gnd:1126463833', 'gnd:36164-1', 'gnd:4132888-7', 'gnd:4151966-8', 'gnd:4154496-1', 'gnd:4165788-3', 'gnd:4177773-6', 'gnd:4297710-1', 'gnd:4331341-3', 'gnd:4496040-2', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A881353434'] | ['Borchardt, Julia', 'Friedrich-Schiller-Universität Jena', 'Metastabilität', 'Elektroschwache Wechselwirkung', 'Fixpunkt', 'Kritisches Phänomen', 'Renormierungsgruppe', 'Standardmodell (Elementarteilchenphysik)', 'Yukawa-Potenzial', 'Higgs-Modell'] | 22 | 13,604 |

Bsister MADS-box genes are known for their predominant role in plant female organ development. The rice Bsister gene OsMADS29 confers the ‘canonical’ Bsister function in rice. With a detailed comparative meta-analysis of all available Bsister gene expression patterns I underline the significance of OsMADS29-like genes within grass ovule and seed development. These genes are all very strongly and more or less exclusively expressed during ovule and/or seed development thus resembling eudicot and gymnosperm Bsister gene expression patterns. I further performed a detailed analysis of the rice gene OsMADS30 showing that it is a non-canonical Bsister gene: it has a comparatively weak and broad expression and T-DNA-insertion lines show no aberrant seed phenotype. I further demonstrated that OsMADS30 evolved under relaxed purifying selection and has a 3’ region that strongly deviates from other grass Bsister genes, including closely related OsMADS30 orthologs from wild rice species. This is due to the recent insertion of a hitherto unknown transposable element. T-DNA insertion lines of OsMADS30 show diminished vegetative growth, which might be first evidence for a neo-functionalization of OsMADS30. I also studied MIKC*-type MADS-domain proteins that function in pollen development: OsMADS62, OsMADS63 and OsMADS68. I demonstrate that they bind not as homodimers but only as heterodimers to DNA. This thesis contributes to a deeper understanding of the developmental and evolutionary significance of various rice MADS-box genes. Eventually it shows how fundamentally different the results of gene duplications even within the same gene family can turn out.'] | ['gnd:1125954469', 'gnd:36164-1', 'gnd:4049271-0', 'gnd:4365090-9', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A881934054'] | ['Schilling, Susanne', 'Friedrich-Schiller-Universität Jena', 'Reis', 'Duplikation'] | 3 | 13,605 |

The required enlargement of the Si NC bandgap is aimed to achieve with the help of quantum confinement (QC). No unambiguous evidence of QC in Si NC/SiC samples were presented in the literature up to now. Even though this also was not possible during this Ph.D. thesis, some necessary preconditions for QC were successfully complied, which are a better understanding and control of the crystallization mechanism, size control of the Si NC and defect passivation. The deposition of amorphous SixC1-x:H layers was conducted by plasma-enhanced chemical vapor deposition. During the annealing step subsequent to layer deposition, H effusion, formation of Si NC, and crystallization of the SiC matrix occurs. All Si NC/SiC samples were subjected to a comprehensive structural and optical characterization. The application of grazing incidence X-ray diffraction, Fourier transform infrared and Raman measurements to Si NC/SiC thin films were significantly improved during this work. The Si NC size control is an indispensable precondition for quantum confinement. For this purpose, two routes were proposed in this work. The Si NC size is shown to increase with increasing Si content of the SixC1-x:H layers. Thus, the Si NC size can be adjusted by adjusting the Si content. The advantage of this method is the fact that singlelayers can be deposited instead of multilayers (ML). The disadvantage is the uncontrollability of the Si NC spacing and the wide size distribution. The second route is with the help of a ML structure. Usually, Si NC/SiC ML structures show strong intermixing during the annealing step and are therefore not suitable for Si NC size control. In this work it is shown that the ML structure can be hindered from intermixing by oxygen incorporation during deposition.'] | ['gnd:1127261223', 'gnd:36164-1', 'gnd:4077445-4', 'gnd:4121476-6', 'gnd:7574326-7', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A883081350'] | ['Weiss, Charlotte', 'Friedrich-Schiller-Universität Jena', 'Silicium', 'Fotovoltaik', 'Nanokristall'] | 22 | 13,606 |

The resulting stationary density profile has been measured in experiments on Bose-Einstein condensates in one-dimensional random potentials, but existing theories are unable to explain the behaviour of the density profile at the center. To improve this situation, we develop an analytical description for the disorder averaged localized density profile. For this purpose, we employ the diagrammatic method of Berezinskii, which we generalize to the case of wave packets, present an analytical expression of the localization length which is valid for small as well as for high energies and finally, develop a self-consistent Born approximation in order to analytically calculate the energy distribution of our wave packet.

This work draws the attention to the optimal morphology of hierarchical and non-hierarchical nanostructures and the morphological characteristics that lead to a rational design of heterogeneous nanocatalysts, especially that have sluggish kinetics. Such optimization is achieved through a deep understanding of the catalytic activity of porous layers based on the impact of pore morphology on pore accessibility.

Nonetheless, the mass transport in hierarchical external nanostructures is the best among the four investigated nanostructures. Hierarchical external nanostructures show an outstanding accessibility of active sites and a kinetic-controlled regime for the species with low diffusion coefficient.

However, while the hardware is there, the current interaction model behind existing design tools is not suitable for non-technical users. Today, 3D printers are operated by fabricating the object in one go, which tends to take overnight due to the slow 3D printing technology. Consequently, the current interaction model requires users to think carefully before printing as every mistake may imply another overnight print. Planning every step ahead, however, is not feasible for non-technical users as they lack the experience to reason about the consequences of their design decisions. In this dissertation, we propose changing the interaction model around personal fabrication tools to better serve this user group. We draw inspiration from personal computing and argue that the evolution of personal fabrication may resemble the evolution of personal computing: Computing started with machines that executed a program in one go before returning the result to the user. By decreasing the interaction unit to single requests, turn-taking systems such as the command line evolved, which provided users with feedback after every input. Finally, with the introduction of direct-manipulation interfaces, users continuously interacted with a program receiving feedback about every action in real-time. In this dissertation, we explore whether these interaction concepts can be applied to personal fabrication as well. ...'] | ['gnd:1135682984', 'gnd:2120681-8', 'gnd:4027266-7', 'gnd:4125909-9', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A890669694'] | ['Mueller, Stefanie', 'Universität Potsdam', 'Interaktion', 'Mensch-Maschine-Kommunikation'] | 11 | 13,611 |

Two long-term irradiation effects are investigated in this thesis: Flux effects (FE) and the late-blooming effect. Small-angle neutron scattering (SANS) and atom-probe tomography (APT) have been applied as characterization method. The investigations on FE show that clusters forming upon high-flux irradiation are smaller and tend to have a higher number density compared to low-flux irradiations at a given neutron fluence. The findings can be explained by a model combining irradiation-enhanced diffusion with deterministic growth. The SANS investigations on the LBE show that the existence of such an effect depends on the irradiation conditions. The APT results indicate that Cu-free clusters are responsible for the observation of LBE.

Such a process behaves as the original one except at the point 0, which plays the role of a semipermeable barrier. More generally, a skew diffusion with several semipermeable barriers, called multi-skew diffusion, is a diffusion everywhere except when it reaches one of the barriers, where it is partially reflected with a probability depending on that particular barrier. Clearly, a multi-skew diffusion can be characterized either as solution of a stochastic differential equation involving weighted local times (these terms providing the semi-permeability) or by its infinitesimal generator as Markov process.'] | ['gnd:10130725-1', 'gnd:1136102000', 'gnd:2120681-8', 'gnd:4128130-5', 'gnd:4128328-4', 'gnd:4274463-5', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A891225560'] | ['Université des sciences et technologies de Lille', 'Mazzonetto, Sara', 'Universität Potsdam', 'Numerisches Verfahren', 'Brownsche Bewegung', 'Diffusionsprozess'] | 16 | 13,613 |

These quantities belong to the class so-called s-numbers and play an important role in the study of the complexity problems since they are lower bounds for worst-case approximation errors.

The historical, institutionalist analysis of the reform process of the "Law to further develop the organisation of basic income support for job seekers" from 2010 analyses the complex shifts in and new regulations for service provision that, in sum, imply decentralisation of basic income support for job seekers.The study shows that these changes can be explained by taking into account negotiation processes between actors, which implies that basic income support for job seekers as an institution reflects power relations between relevant actors. Thus, the analysis contributes to a better understanding of current reform processes in German labour market policy and social policy. In theoretical terms, the study contributes to the theoretical discussion in historical institutionalism. It discusses the strengths and weaknesses of the approach and develops potential paths for theoretical improvement.', 'Die Studie untersucht Veränderungen in der Leistungserbringung der Grundsicherung für Arbeitsuchende in Bezug auf Zentralisierung und Dezentralisierung. In einer historisch-institutionalistischen Analyse des Reformprozesses zum Weiterentwicklungsgesetz 2010 werden die komplexen Verschiebungen und Neuregelungen der Leistungserbringung betrachtet, die insgesamt eine Dezentralisierung in der Grundsicherung für Arbeitsuchende implizieren.Die Autorin weist nach, dass diese Veränderungen sich mit den Aushandlungsprozessen von Akteuren erklären lassen, die die Institution Grundsicherung für Arbeitsuchende als Ausdruck geronnener Machtkonflikte konstituieren. Die Untersuchung trägt so zum Verständnis aktueller Reformprozesse in der deutschen Arbeitsmarkt- und Sozialpolitik bei. In theoretischer Hinsicht leistet die Studie einen Beitrag zur historisch-institutionalistischen Theoriediskussion, indem sie Stärken und Schwächen des Ansatzes diskutiert und Weiterentwicklungsmöglichkeiten aufzeigt.']] | ['gnd:117513-0', 'gnd:36175-6', 'gnd:4011882-4', 'gnd:4068155-5', 'gnd:7686166-1', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A89811781X'] | ['Nomos Verlagsgesellschaft', 'Westfälische Wilhelms-Universität Münster', 'Deutschland', 'Zuständigkeit', 'Grundsicherung für Arbeitsuchende'] | 25 | 13,626 |
