description: KTaO_3-based solid solutions exhibit a variety of interesting physical phenomena. To better understand these phenomena, we performed first-principles calculations on [K_{1-x}, Li_x]TaO_3 (KLT) and K[Ta_{1-x}, Nb_x]O_3 (KTN) supercells. Our results show Li displacements and potential barrier heights in KLT that are in excellent agreement with values obtained from experimental fits. Dramatic changes in B-site dynamical charges occur in KTN in response to changes in near neighbor (nn) coordination. These effects can be explained by heterogeneity in the local electronic dielectric permittivity.

Creators: name: Schmid, Martina
Publisher: name: Freie Universität Berlin
Year: 2017
Subjects: subject: 500 Naturwissenschaften und Mathematik::530 Physik

description: Light management has gained wide interest for various types of solar cells. This paper reviews the application of nanostructures for light management to chalcopyrite (CIGSe) type solar cells. Firstly, the relevance of light management for CIGSe solar cells will be introduced and applicable concepts of nanostructures for absorption enhancement discussed. The development of ultra- thin CIGSe solar cells and examples for nanoparticle fabrication techniques together with their chances and challenges for application to CIGSe will be presented. Particular attention will be paid to nanostructures that have been applied to CIGSe solar cells, revealing many theoretical and some experimental results. Metallic and dielectric nanostructures as well as intrinsic nanotextures will be covered. For the future, combined considerations of optical and electrical properties will gain in importance.

description: We classify the symplectic automorphism groups for cubic fourfolds. The main inputs are the global Torelli theorem for cubic fourfolds and the classification of the fixed-point sublattices of the Leech lattice. Among the highlights of our results, we note that there are 34 possible groups of symplectic automorphisms, with 6 maximal cases. The six maximal cases correspond to 8 non-isomorphic, and isolated in moduli, cubic fourfolds; six of them previously identified by other authors. Finally, the Fermat cubic fourfold has the largest possible order (174,960) for the automorphism group (non-necessarily symplectic) among all smooth cubic fourfolds.

description: The fate and observable properties of gamma-ray burst jets depend crucially on their interaction with the progenitor material that surrounds the central engine. We present a semi-analytical model of such interaction, which builds upon several previous analytical and numerical works, aimed at predicting the angular distribution of jet and cocoon energy and Lorentz factor after breakout, given the properties of the ambient material and of the jet at launch. Using this model, we construct synthetic populations of structured jets, assuming either a collapsar (for long gamma-ray bursts -- LGRBs) or a binary neutron star merger (for short gamma-ray bursts -- SGRBs) as progenitor. We assume all progenitors to be identical, and we allow little variability in the jet properties at launch: our populations therefore feature a quasi-universal structure. These populations are able to reproduce the main features of the observed LGRB and SGRB luminosity functions, although several uncertainties and caveats remain to be addressed.

description:  An Energy-efficient building is enhancing a worldwide movement as a policy to lessen the carbon footprint. With the intention of zero energy building in sub-tropical climates, exertion should be placed to minimize the overall energy usage to the greatest scope by incorporating apposite construction skills into the whole design process. Suitable building envelope resources are one of the most effective ways to manage energy flows, minimize energy loss, and maintain a comfortable environment for occupants. In the present paper, a conventional building(Educational) in Hong Kong is considered and the goal is to identify and prioritize the potentialenergy saving opportunities through the implications of multiple envelopes (walls, windows,etc.) fabric using dynamic BIM-BPS process for potential retrofitting. A conceptual frameworkis proposed for comprehensive energy assessment using BIM (e.g. Revit 2019) and BPS tools(e.g. e-QUEST) to simulate the energy performance of the building. Using a calibrated model,several high performances envelop fabric are considered to perform a parametric investigation(e.g. walls, windows) through active simulation process. In order to achieve more realisticconditioning, an assumed occupancy profile also considered during the energy analysis. Resultshave shown that a significant saving of 11.45% in yearly entailed total building energy. Thestudy can help with the decision-making analysis regarding future retrofitting opportunities in asub-tropical climate.

description: Background This study evaluates primary care practices' engagement with various features of a quality improvement (QI) intervention for patients with coronary heart disease (CHD) in four Australian states. Methods Twenty-seven practices participated in the QI intervention from November 2019 -November 2020. A combination of surveys, semi-structured interviews and other materials within the QUality improvement in primary care to prevent hospitalisations and improve Effectiveness and efficiency of care for people Living with heart disease (QUEL) study were used in the process evaluation. Data were summarised using descriptive statistical and thematic analyses for 26 practices. Results Sixty-four practice team members and Primary Health Networks staff provided feedback, and nine of the 63 participants participated in the interviews. Seventy-eight percent (40/54) were either general practitioners or practice managers. Although 69% of the practices selfreported improvement in their management of heart disease, engagement with the intervention varied. Forty-two percent (11/26) of the practices attended five or more learning workshops, 69% (18/26) used Plan-Do-Study-Act cycles, and the median (Interquartile intervals) visits per practice to the online SharePoint site were 170 (146-252) visits. Qualitative data identified learning workshops and monthly feedback reports as the key features of the intervention. Conclusion Practice engagement in a multi-featured data-driven QI intervention was common, with learning workshops and monthly feedback reports identified as the most useful features. A better understanding of these features will help influence future implementation of similar interventions.

The control of reaching movements by young infants
Creators: name: Mathew, Anne
Publisher: name: The Australian National University
Year: 1990

description: Infant reaching movements have tortuous handpaths and multipeaked speed curves. It has been hypothesised that these movements comprise sequences of ballistic motor units whose boundaries are marked by troughs in the speed-time curve. Error correction, if any, is assumed to take place between and not within these movement units. This hypothesis was investigated in this study. Samples of reaches were obtained from groups of infants aged 4.5, 6 and 7.5 months as split-screen video recordings, which were then transcribed as sequences of (X,Y,Z) hand coordinates. There was an improvement in overall efficiency in reaching across the three age groups. Movement paths were examined for evidence of initial aiming and subsequent correction. At all ages, the initial direction of the movement was correlated with target direction, providing evidence that the hand was aimed towards the target. Additionally, changes in movement direction made after the commencement of the movement tended to curve the hand path towards the target, providing evidence of error Correction. Local minima of hand speed evident within segments of continuous movement were associated with tum towards the target. However, the movement path was also curved towards the target within the movement elements bounded by these minima. This finding was seen as being consistent with 'continuous' correction of movement errors and as contrary to the suggestion that infant movements are concatenations of ballistic movement units whose boundaries are marked by troughs in the speed profile.

description: What length of rope (of given diameter) is required to tie a particular knot? To answer this question, we define some new notions of thickness for a space curve, one based on Gromov's distortion, and another generalizing the thickness of Litherland, Simon et al. We prove a basic inequality between these thickness measures, and show that the distortion thickness is upper semi-continuous in the C^0 topology, suggesting that shortest curves of thickness 1 should exist in each knot class.

description: The three-state Majorana model in the presence of dissipation is considered. Different models of system-environment interaction are explored, ranging from situation where dissipation is the main effect to regimes where dephasing is mainly produced. It is shown that the detrimental effects of the noise are stronger in the presence of dissipation than in the presence of dephasing. The role of temperature is also discussed.

description: This work aims to contribute to the study of the origins of cosmic rays, and broadly, to the advancement of both data analysis methods and instrumentation for very-high-energy γ-ray astronomy. First, reviewing the state of γ-ray astronomy, we show how gains in sensitivity can be achieved through sophisticated data analyses and improved instrumental designs. We then develop such an improved analysis method for the Very Energetic Radiation Imaging Telescope Array System (VERITAS) by combining Image Template Method (ITM) with Boosted Decision Trees (BDT), and study its performance, attaining a 30-50% improvement in integral sensitivity over the instrument’s standard analysis. Systematic issues in spectral reconstruction that the analysis displays are resolved satisfactorily by imposing a more stringent condition on the selection of its energy threshold. We employ the newly developed analysis to measure the γ-ray energy spectrum of the starburst galaxy M82, and combining our result with a measurement from the Fermi Large Area Telescope (Fermi-LAT), we find that a single power law fits the spectrum well between 100 GeV and 10 TeV, with no evidence for a spectral break or a cutoff. We conclude that this is in line with the current understanding that M82 is not a good proton calorimeter. Finally, we detail the design, implementation, and performance of the optical alignment system of the prototypeSchwarzschild-Couder Telescope (pSCT) for the Cherenkov Telescope Array (CTA), a novel two-mirror design that addresses many shortcomings of current instruments.

description: Deep generative modeling is an increasingly popular area of machine learning that takes advantage of recent developments in neural networks in order to estimate the distribution of observed data. In this dissertation we introduce three advances in this area. The first one, Maximum Entropy Flow Networks, allows to do maximum entropy modeling by combining normalizing flows with the augmented Lagrangian optimization method. The second one is the continuous Bernoulli, a new [0,1]-supported distribution which we introduce with the motivation of fixing the pervasive error in variational autoencoders of using a Bernoulli likelihood for non-binary data. The last one, Deep Random Splines, is a novel distribution over functions, where samples are obtained by sampling Gaussian noise and transforming it through a neural network to obtain the parameters of a spline. We apply these to model texture images, natural images and neural population data, respectively; and observe significant improvements over current state of the art alternatives.

description: We analyze charge tunneling statistics and current noise in a superconducting single-electron transistor in a regime where the Josephson-quasiparticle cycle is the dominant mechanism of transport. Due to the interplay between Coulomb blockade and Josephson coherence, the probability distribution for tunneling events strongly deviates from a Poissonian and displays a pronounced even--odd asymmetry in the number of transmitted charges. The interplay between charging and coherence is reflected also in the zero-frequency current noise which is significantly quenched when the quasi-particle tunneling rates are comparable to the coherent Cooper-pair oscillation frequency. Furthermore the finite frequency spectrum shows a strong enhancement near the resonant transition frequency for Josephson tunneling.

description: Following the recent financial crisis, financial regulators have placed a strong emphasis on reducing expectations of government support for banks, and on better managing and assessing risks in the banking system. This thesis considers three current topics in credit risk and the statistical problems that arise there.
      The first of these topics is expectations of government support in distressed banks. We utilize unique features of the European credit default swap market to find that market expectations of European government support for distressed banks have decreased -- an important development in the credibility of financial reforms.
      The second topic we treat is the estimation of covariance matrices from the perspective of market risk management. This problem arises, for example, in the central clearing of credit default swaps. We propose several specialized loss functions, and a simple but effective visualization tool to assess estimators. We find that proper regularization significantly improves the performance of dynamic covariance models in estimating portfolio variance.
      The third topic we consider is estimation risk in the pricing of financial products. When parameters are not known with certainty, a better informed counterparty may strategically pick mispriced products. We discuss how total estimation risk can be minimized approximately. We show how a premium for remaining estimation risk may be determined when one counterparty is better informed than the other, but a market collapse is to be avoided, using a simple example from loan pricing. We illustrate the approach with credit bureau data.

description: The electron-phonon interaction (EPI) is instrumental in a wide variety of phenomena in solid-state physics, such as electrical resistivity in metals, carrier mobility, optical transition and polaron effects in semiconductors, lifetime of hot carriers, transition temperature in BCS superconductors, and even spin relaxation in diamond nitrogen-vacancy centers for quantum information processing. However, due to the weak EPI strength, most phenomena have focused on electronic properties rather than on phonon properties. One prominent exception is the Kohn anomaly, where phonon softening can emerge when the phonon wavevector nests the Fermi surface of metals. Here we report a new class of Kohn anomaly in a topological Weyl semimetal (WSM), predicted by field-theoretical calculations, and experimentally observed through inelastic x-ray and neutron scattering on WSM tantalum phosphide (TaP). Compared to the conventional Kohn anomaly, the Fermi surface in a WSM exhibits multiple topological singularities of Weyl nodes, leading to a distinct nesting condition with chiral selection, a power-law divergence, and non-negligible dynamical effects. Our work brings the concept of Kohn anomaly into WSMs and sheds light on elucidating the EPI mechanism in emergent topological materials.

By analyzing the current density and the heat flux in the kappa-distributed plasma, we derive the corresponding transport coefficients, including the electric conductivity, the thermal conductivity and thermoelectric coefficient. Besides, we derive the coefficients of Hall, Nernst and Leduc-Righi effects in the kappa-distributed plasma. It is shown that these new transport coefficients depend strongly on the kappa-parameter and only in the limit kappa to infinity, they recover the traditional forms in the plasma based on a Maxwellian distribution. We also numerically analyze the role of the kappa-parameter in the kappa-dependent transport coefficients.

description: Let X be a smooth, projective variety defined over a local field K. Following Manin, two K-points of X are called R-equivalent if they can be joined by a rational curve defined over K. The main result of this note shows that if there are only finitely many R-equivalence classes over the algebraic closure of K then the same holds over K. This also yields the unirationality of several classes of varieties over K.

description: In this paper, we propose an efficient high order semi-Lagrangian (SL) discontinuous Galerkin (DG) method for solving linear convection-diffusion equations. The method generalizes our previous work on developing the SLDG method for transport equations (J. Sci. Comput. 73: 514-542, 2017), making it capable of handling additional diffusion and source terms. Within the DG framework, the solution is evolved along the characteristics; while the diffusion term is discretized by the local DG (LDG) method and integrated along characteristics by implicit Runge-Kutta methods together with source terms. The proposed method is named the `SLDG-LDG' method and enjoys many attractive features of the DG and SL methods. These include the uniformly high order accuracy (e.g. third order) in space and in time, compact, mass conservative, and stability under large time stepping size. An $L^2$ stability analysis is provided when the method is coupled with the first order backward Euler discretization. Effectiveness of the method are demonstrated by a group of numerical tests in one and two dimensions.

description: We show in theory, simulations, and experiments that, by applying random metallic nanomeshes, a broad-band multilayered structure with a 12 nm thick a-Si film as the active layer can absorb 89% of the total solar energy in the visible range from 400 nm to 700 nm. Such broadness and high absorption can be attributed to the random scattering introduced by the aperiodic metallic nanomeshes and the plasmonic-metamaterial design. The broadband and smooth electromagnetic response, combined with a very high absorption, is desired for solar energy harvesting devices, making this structure a good candidate for high efficiency photovoltaics with ultra-thin active layers.

description: Excerpts from the report Introduction: Beef immediately after slaughter will have a temperature of 95° to 98° F. After slaughter the air temperature and air movement in the chilling room is regulated to lower the temperature of the beef as quickly as possible without freezing the outside surface of the meat. Beef will maintain its bloom and quality best when it is cooled and held at a temperature between 31° and 35°. If the temperature of the beef is allowed to rise above 35°, the tendency for mold to develop on the surface increases. Therefore, if beef is to maintain its quality and appearance the temperature should be kept between 31° and 35°. The purpose of this test was to compare the performance of two mechanically refrigerated cars, two mechanically refrigerated trailers on a flat-car, and a water-ice car, as a control, when transporting freshly killed beef. The test was conducted between Lincoln, Nebr. , and Philadelphia, Pa. , in July 1958. Performances are measured in terms of temperatures and humidities maintained within the cars, fuel consumption, and refrigeration charges.
Decoherence due to three-body loss and its effect on the state of a Bose-Einstein condensate

description: A Born-Markov master equation is used to investigate the decoherence of the state of a macroscopically occupied mode of a cold atom trap due to three-body loss. In the large number limit only coherent states remain pure for times longer than the decoherence time: the time it takes for just three atoms to be lost from the trap. For large numbers of atoms (N>10^4) the decoherence time is found to be much faster than the phase collapse time caused by intra-trap atomic collisions.

description: In this paper, an application of automated theorem proving techniques to computational semantics is considered. In order to compute the presuppositions of a natural language discourse, several inference tasks arise. Instead of treating these inferences independently of each other, we show how integrating techniques from formal approaches to context into deduction can help to compute presuppositions more efficiently. Contexts are represented as Discourse Representation Structures and the way they are nested is made explicit. In addition, a tableau calculus is present which keeps track of contextual information, and thereby allows to avoid carrying out redundant inference steps as it happens in approaches that neglect explicit nesting of contexts.

description: The Joint Africa-EU Strategy (JAES), which was adopted in 2007, aimed to break with the traditional donor-recipient relationship between the EU and Africa and to develop a true partnership. The concept of partnership has been central in EU-Africa relations ever since the Lomé Agreement (1975), but many have argued that it has been eroded by conditionalities and the end of special trade preferences. Ideally, a partnership is characterized by shared values, equality and trust, but are these principles reflected in the JAES? This study investigates this question by focusing on the thematic partnerships on peace and security and democratic governance and human rights. The paper argues that, despite the power asymmetries between the EU and Africa, the JAES has been characterized by equality in decision-making and by African ownership in capacity-building. However, while the JAES may objectively be based on shared values, the EU and the AU have often differed on how to apply those values in concrete situations, more particularly on the question which type of intervention is acceptable (conditionality, military intervention, etc.). Moreover, the analysis identifies a general feeling of mistrust amongst both parties in the partnership.

description: A core task in machine learning, and the topic of this thesis, is developing faster and more accurate methods of posterior inference in probabilistic models. The thesis has two components. The first explores using deterministic methods to improve the efficiency of Markov Chain Monte Carlo (MCMC) algorithms. We propose new MCMC algorithms that can use deterministic methods as a “prior” to bias MCMC proposals to be in areas of high posterior density, leading to highly efficient sampling. In Chapter 2 we develop such methods for continuous distributions, and in Chapter 3 for binary distributions. The resulting methods consistently outperform existing state-of-the-art sampling techniques, sometimes by several orders of magnitude. Chapter 4 uses similar ideas as in Chapters 2 and 3, but in the context of modeling the performance of left-handed players in one-on-one interactive sports.
      The second part of this thesis explores the use of stable stochastic gradient descent (SGD) methods for computing a maximum a posteriori (MAP) estimate in large-scale machine learning problems. In Chapter 5 we propose two such methods for softmax regression. The first is an implementation of Implicit SGD (ISGD), a stable but difficult to implement SGD method, and the second is a new SGD method specifically designed for optimizing a double-sum formulation of the softmax. Both methods comprehensively outperform the previous state-of-the-art on seven real world datasets. Inspired by the success of ISGD on the softmax, we investigate its application to neural networks in Chapter 6. In this chapter we present a novel layer-wise approximation of ISGD that has efficiently computable updates. Experiments show that the resulting method is more robust to high learning rates and generally outperforms standard backpropagation on a variety of tasks.
Exciton-relaxation dynamics in lead halides

description: We survey recent comprehensive studies of exciton relaxation in the crystals of lead halides. The luminescence and electron-spin-resonance studies have revealed that excitons in lead bromide spontaneously dissociate and both electrons and holes get self-trapped individually. Similar relaxation has been also clarified in lead chloride. The electron-hole separation is ascribed to repulsive correlation via acoustic phonons. Besides, on the basis of the temperature profiles of self-trapped states, we discuss the origin of luminescence components which are mainly induced under one-photon excitation into the exciton band in lead fluoride, lead chloride, and lead bromide.
