description: The analysis of samples of random objects that do not lie in a vector space is gaining increasing attention in statistics. An important class of such object data is univariate probability measures defined on the real line. Adopting the Wasserstein metric, we develop a class of regression models for such data, where random distributions serve as predictors and the responses are either also distributions or scalars. To define this regression model, we utilize the geometry of tangent bundles of the space of random measures endowed with the Wasserstein metric for mapping distributions to tangent spaces. The proposed distribution-to-distribution regression model provides an extension of multivariate linear regression for Euclidean data and function-to-function regression for Hilbert space valued data in functional data analysis. In simulations, it performs better than an alternative transformation approach where one maps distributions to a Hilbert space through the log quantile density transformation and then applies traditional functional regression. We derive asymptotic rates of convergence for the estimator of the regression operator and for predicted distributions and also study an extension to autoregressive models for distribution-valued time series. The proposed methods are illustrated with data on human mortality and distributional time series of house prices.

description: Die Kompetenz zur fachdidaktischen Forschung liegt bei den Pädagogischen Hochschulen, die in der Schweiz kein Promotions- und Habilitationsrecht haben. Forschende an diesen Hochschulen sind daher darauf angewiesen, an einem Fachdidaktiklehrstuhl ausserhalb ihres Arbeits- und Forschungsorts zu promovieren. Doch an Universitäten der deutschsprachigen Schweiz gibt es nur wenige und nur für vereinzelte Disziplinen Lehrstühle für Fachdidaktik. An universitären Hochschulen im Ausland, darunter auch Pädagogische Hochschulen, ist diese fachdidaktische Forschungskompetenz hingegen vorhanden. Dies führt dazu, dass das Promovieren im benachbarten Ausland attraktiv ist. Dabei kann grob zwischen individuellen und institutionalisierten Promotionspartnerschaften unterschieden werden. Insbesondere die institutionalisierten Promotionspartnerschaften bieten interessante Möglichkeiten, obwohl auch bei ihnen immer ein bedenkliches Abhängigkeitsverhältnis der Schweizer Pädagogischen Hochschule von der Hochschule im Ausland besteht.
description: The competence for research in subject-specific education lies with the universities of teacher education, which in Switzerland do not have the right to award doctorates and habilitations. Researchers at these universities are therefore dependent on obtaining a doctorate from a professorship in subject-specific education outside their place of work and research. At universities in German-speaking Switzerland there are only a few chairs for subject-specific education, however, and only for some disciplines. At universities abroad, by contrast, this research expertise in subject-specific education is available. This makes doctoral studies in neighbouring countries attractive. A rough distinction can be drawn between individual and institutionalised doctoral partnerships. Institutionalised doctoral partnerships in particular offer interesting opportunities although even this form of cooperation is always characterised by a relationship of dependence between the Swiss university of teacher education and the university abroad, which is worth considering.

description: Traditionelle Modelle zur Anregung des Lernens zukünftiger Lehrpersonen im Praktikum fokussieren die Funktionen von Mentorinnen und Mentoren vor allem auf die Beobachtung von Unterricht und dessen Nachbesprechung. In den letzten Jahren wurden zunehmend Ansätze eingeführt, die ein erweitertes Repertoire lernförderlicher Kooperation im Praktikum vorschlagen. Modelle wie das reflexive Praktikum, das fachspezifisch-pädagogische Coaching oder das Educative Mentoring empfehlen auf einer sozialkonstruktivistischen Theoriebasis erweiterte und aktivere Funktionen von Mentorats- oder Praxislehrpersonen. Zusätzlich zur retrospektiven Reflexion von Unterricht werden bereits dessen Planung und Durchführung als explizite Lerngelegenheiten gestaltet. Im Beitrag werden die drei genannten Ansätze exemplarisch dargestellt und diskutiert.

description: We continue the study of spherically symmetric vacuum space-times in loop quantum gravity by treating the interior of a black hole. We start from a midi-superspace approach, but a simple gauge fixing leads to a Kantowski--Sachs form for the variables. We show that one can solve the quantum theory exactly in the (periodic) connection representation, including the inner product. The evolution can be solved exactly by de-parameterizing the theory and can be easily interpreted as a semi-classical evolution plus quantum corrections. A relational evolution can also be introduced in a precise manner, suggesting what may happen in situations where it is not possible to de-parameterize. We show that the singularity is replaced by a bounce at which quantum effects are important and that the extent of the region at the bounce where one departs from classical general relativity depends on the initial data.

First Order Phase Transition in a Two Higgs-doublet Model with $M_{h}>M_{W}$

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We study the 3d effective field theory of a weakly coupled two Higgs-doublet scalar model at high temperature. Our model has three scalar quartic couplings and an $O(4)$ symmetry which is spontaneously broken by a nonzero scalar field $vev$ at zero temperature. Using high temperature perturbation theory, renormalization group arguments in $4-ε$ dimensions, as well as $1/N$ expansion techniques in 3 dimensions, we argue that the transition from the high temperature symmetry restoring phase to the low temperature phase is first order for a range of scalar couplings. This result is not due to gauge couplings. We discuss the implications of our results for baryogenesis in the two Higgs-doublet electroweak model, especially when the lightest neutral Higgs is heavier than the W--bosons.

Die Matrixorganisation kann den Wissensaustausch fördern und dem wissenschaftlichen Personal vielfältige Karrieren innerhalb der Organisation eröffnen. Eine Matrixorganisation ist jedoch eine grosse Herausforderung für die Führungspersonen. Das Funktionieren der Organisation ist noch stärker als sonst von der klaren Definition der Kompetenzen und der Übernahme der Führungsrollen abhängig.

Subjects: classificationCode: 350101
subject: Accounting theory and standards

description: While accounting education in Cambodia has been remarkably improved at present, the focus is more on know-how rather than know-why. To some extent, this limits students’ understanding of the complex reality of accounting. This article provides a concise overview of accounting thoughts that have been examined and debated for some decades in the wider accounting literature. It aims to raise awareness of the importance of this topic among accounting students in Cambodia. It suggests that attention to accounting philosophy be needed in the current accounting education system so that accounting students, who will be the future accounting practitioners or researchers in the Cambodian accounting field, have a better understanding of the concept and importance of accounting for organizations and societies.

description: Abstract

Background: Infection prevention and control is a critical component of the invasive medical procedures. The Same control measures are also recommended in any healthcare organizations to prevent the spread of infection. For colonization to occur, microorganisms must exist and reproduce without invading or harming surrounding tissue. A cellular reaction is now triggered by the invading microbes, which is what infection entails. Placing barriers between vulnerable hosts (someone lacking effective innate or acquired defense) and the microbe is critical to infection prevention.

Tout rigide juge que je [fol. 89 v] suis au reste de moi et de tous mes travaux, je n'oserai rien que ces observations ne sauraient être désagréables aux connaisseurs. Et comme vous en êtes un des plus habiles, jugez Monsieur, combien la nouvelle me sera agréable. Si j'ai l'honneur d'apprendre que vous les avez trouvées non pas tout à fait indignes d'y jeter un clin d'oeil gracieux.

Assurez-toujours votre vénérable Maffei de ma profonde dévotion et soyez persuadé géométriquement que personne ne pourra jamais être avec tant d'attachement que je le serai toujours,

A Tag-Based, Logical Access-Control Framework for Personal File Sharing

description: People store and share ever-increasing numbers of digital documents, photos, and other files, both on personal devices and within online services. In this environment, proper access control is critical to help users obtain the benefits of sharing varied content with different groups of people while avoiding trouble at work, embarrassment, identity theft, and other problems related to unintended disclosure. Current approaches often fail, either because they insufficiently protect data or because they confuse users about policy specification. Historically, correctly managing access control has proven difficult, timeconsuming, and error-prone, even for experts; to make matters worse, access control remains a secondary task most non-experts are unwilling to spend significant time on. To solve this problem, access control for file-sharing tools and services should provide verifiable security, make policy configuration and management simple and understandable for users, reduce the risk of user error, and minimize the required user effort. This thesis presents three user studies that provide insight into people’s access-control needs and preferences. Drawing on the results of these studies, I present Penumbra, a prototype distributed file system that combines semantic, tag-based policy specification with logicbased access control, flexibly supporting intuitive policies while providing high assurance of correctness. Penumbra is evaluated using a set of detailed, realistic case studies drawn from the presented user studies. Using microbenchmarks and traces generated from the case studies, Penumbra can enforce users’ policies with overhead less than 5% for most system calls. Finally, I present lessons learned, which can inform the further development of usable access-control mechanisms both for sharing files and in the broader context of personal data.

description: We use the recently calculated two--loop anomalous dimensions of current-current operators, QCD and electroweak penguin operators to construct the effective Hamiltonian for $ΔS=1$ transitions beyond the leading logarithmic approximation. We solve the renormalization group equations and give the numerical values of Wilson coeff. functions. We propose a new semi-phenomenological approach to hadronic matrix elements which incorporates the data for $CP$-conserving $K \rightarrow ππ$ amplitudes and allows to determine the matrix elements of all $(V-A)\otimes (V-A)$ operators in any renormalization scheme and do a renormalization group analysis of all hadronic matrix elements $\langle Q_i(μ) \rangle$. We compare critically our treatment of these matrix elements with those given in the literature. We find in the NDR scheme $\epe = (6.7 \pm 2.6)\times 10^{-4}$ in agreement with the experimental findings of E731. We point out however that the increase of $\langle Q_6 \rangle$ by only a factor of two gives $\epe = (20.0 \pm 6.5)\times 10^{-4}$ in agreement with the result of NA31. The dependence of $\epe$ on $Λ_{\bar{MS}}$, $m_t$ and $\langle Q_{6,8} \rangle$ is presented.

description: We construct the supersymmetric completion of quartic $R+R^4$-actions in the ten-dimensional effective action of the heterotic string. Two invariants, of which the bosonic parts are known from one-loop string amplitude calculations, are obtained. One of these invariants can be generalized to an $R+F^2+F^4$-invariant for supersymmetric Yang-Mills theory coupled to supergravity. Supersymmetry requires the presence of $B\wedge R\wedge R\wedge R\wedge R$-terms, ($B\wedge F\wedge F\wedge F\wedge F$ for Yang-Mills) which correspond to counterterms in the Green-Schwarz anomaly cancellation. Within the context of our calculation the $ζ(3)R^4$-term from the tree-level string effective action does not allow supersymmetrization.

These curves, determined from isofield magnetization versus temperature measurements and the virial theorem of superconductivity, probe the order parameter amplitude near the upper critical field. The striking differences between the Nb and the high-T_c curves clearly indicate for the latter cases the presence of a unique superconducting condensate below and above T_c.

description: Scientific Computation provides a critical role in the scientific process because it allows us ask complex queries and test predictions that would otherwise be unfeasible to perform experimentally. Because of its power, Scientific Computing has helped drive advances in many fields ranging from Engineering and Physics to Biology and Sociology to Economics and Drug Development and even to Machine Learning and Artificial Intelligence. Common among these domains is the desire for timely computational results, thus a considerable amount of human expert effort is spent towards obtaining performance for these scientific codes. However, this is no easy task because each of these domains present their own unique set of challenges to software developers, such as domain specific operations, structurally complex data and ever-growing datasets. Compounding these problems are the myriads of constantly changing, complex and unique hardware platforms that an expert must target. Unfortunately, an expert is typically forced to reproduce their effort across multiple problem domains and hardware platforms. In this thesis, we demonstrate the automatic generation of expert level high-performance scientific codes for Dense Linear Algebra (DLA), Structured Mesh (Stencil), Sparse Linear Algebra and Graph Analytic. In particular, this thesis seeks to address the issue of obtaining performance on many complex platforms for a certain class of matrix-like operations that span across many scientific, engineering and social fields. We do this by automating a method used for obtaining high performance in DLA and extending it to structured, sparse and scale-free domains. We argue that it is through the use of the underlying structure found in the data from these domains that enables this process. Thus, obtaining performance for most operations does not occur in isolation of the data being operated on, but instead depends significantly on the structure of the data.

The barrier height is found to be about 0.7 eV, and is reduced after annealing at 180 $^\circ$C, implying that the gap can be tuned by changing the degree of oxidation. A lower limit of the GO mobility was found to be 850 cm$^2$/Vs, rivaling silicon. {\it In situ} local oxidation of patterned epitaxial graphene has been achieved.

description: Objective: To evaluate outcomes associated with adherence to levothyroxine (LT4) in the US adult hypothyroidism population. Methods: We used data from Truven’s MarketScan databases from 1 July 2011 through 31 December 2015. Patients aged 18 or older were diagnosed with hypothyroidism (confirmed at least twice) and prescribed LT4. Patients were excluded if they did not have continuous insurance coverage or if they received a diagnosis of thyroid cancer or pregnancy during the study period. Multivariable analyses on a matched cohort of adherent and nonadherent patients examined the relationships among patient outcomes and adherence, defined as the proportion of days covered ≥80%. Outcomes included all-cause and hypothyroidism-related medical costs and resource utilization and comorbid diagnoses measured over the 1 year post-period following the first prescription for LT4. The analyses controlled for patient age, sex, region of residence, type of insurance coverage, diagnosing physician and pre-period general health status as proxied by the Charlson Comorbidity Index. Results: Prior to matching, there were 168,457 patients identified as adherent and 198,443 patients identified as nonadherent. The matched cohort consisted of 318,628 individuals, with equal numbers of adherent and nonadherent patients (n = 159,314). Patients who were adherent used significantly fewer resources and had significantly lower all-cause ($14,136 vs. $14,926; p p Conclusions: Compared to nonadherence, adherence to LT4 among patients with hypothyroidism was associated with a significant reduction in all-cause and hypothyroidism-related costs and resource utilization as well as significantly lower rates of many comorbid diagnoses.

description: This thesis is focused on expanding the use of spatial modelling approaches for applications in ecology. Spatial ecology is about understanding the processes that give rise to spatial patterns in ecological data. In addition to developing a purely scientific understanding, insights into these processes are essential for the effective monitoring and conservation management of ecological systems. However, for many ecological problems, the detectability of animals is imperfect, requiring the use of complex observation models that can account for this. In this thesis we focus on two such models: distance sampling and spatial capture-recapture (SCR). For both these models we incorporate spatially structured random effects to provide a non-parametric method for describing spatial variation in species’ abundance, and to address the problem of spatial auto-correlation. These complex models require the use of computationally efficient random effect structures and inference methods. In particular, we use a sparse stochastic partial differential equation (SPDE) approach as well as low rank penalised smoothing splines. We also draw links between these two approaches in order to illuminate the technically challenging results underpinning the SPDE approach. For inference in distance sampling models, we use a novel approach to achieve a one-stage model fit based on iterated model fitting using approximate Bayesian methods. For inference in SCR models, we use Laplace approximate maximum likelihood methods. We present models that have the necessary complexity to jointly model complex ecological and observation processes, as well as providing efficient methods to fit the models in practice. We conclude by discussing related avenues for future research that are motivated by applied problems in the field of spatial ecology.
Extraction of Coupling Information From $Z' \to jj$

description: An analysis by the ATLAS Collaboration has recently shown, contrary to popular belief, that a combination of strategic cuts, excellent mass resolution, and detailed knowledge of the QCD backgrounds from direct measurements can be used to extract a signal in the $Z' \to jj$ channel in excess of $6σ$ for certain classes of extended electroweak models. We explore the possibility that the data extracted from $Z$ dijet peak will have sufficient statistical power as to supply information on the couplings of the $Z'$ provided it is used in conjunction with complimentary results from the $Z' \to \ell^+ \ell^-$ `discovery' channel. We show, for a 1 TeV $Z'$ produced at the SSC, that this technique can provide a powerful new tool with which to identify the origin of $Z'$'s.

description: This thesis is broken into three main sections tracing the steps of the development of a new framework to search for and characterize planets from the WASP survey. While all methods were developed specifically for the WASP project, the principles are easily transferable to any ground or space based survey. In the first part of the thesis, I discuss the development of two machine learning methods, a Random Forest Classifier and a Convolutional Neural Network, that are able to find new exoplanet candidates from WASP archival data and lightcurves. In preparing the training dataset, I also created a standardized catalog of 1,041 false positives from SuperWASP, the northern component of WASP, that were verified with additional observations from other instruments. The second part of the thesis begins by discussing the results of the machine learning methods. In the analysis of the resulting probabilities, several patterns began to emerge that indicated the differing predictions between the algorithms carry useful information in itself. This realization sparked the development of a new “stacking” framework where the predictions of a number of different machine learning methods areused as the input to a second-level classifier that makes the final prediction. This method is straightforward to implement and demonstrates an improved performance over any individual classifier, making the stacked approach ideal for future large surveys. I use the model to classify and rank more than 100,000 lightcurves in the WASP archive that do not yet have a disposition associated with them and discuss the candidates that are rated most favourably. Finally, in part three I discuss what to do once a candidate is confirmed to be a planet. In particular, I describe a new MCMC method that combines the likelihood fits of transit and radial velocity data with prior knowledge from several sources including optical and infrared spectrophotometric measurements and the parallax measurements from Gaia to constrain the stellar parameters. I apply the method to characterize two new hot Jupiter planets found by the WASP collaboration and confirmed with SOPHIE and TESS measurements. WASP-186b is a dense (4.22 ± 0.18MJ, 1.11 ± 0.03RJ ) planet on an eccentric (e=0.33 ± 0.01) 5-day orbit around a mid-F type star. While also in a ~5 day orbit, WASP-187b is puffed up (0.8 ± 0.09MJ, 1.64 ± 0.05RJ ) and orbiting a star that has begun evolving away from the main sequence.

description: Iron-cobalt (FeCo) and its various alloys have many applications where soft magnetic materials are needed, especially in high temperature applications. Recent research has looked into the nanocrystallization of amorphous alloys of FeCo and very briefly into the oxidation of FeCo nanoparticles and bulk materials. Attempts will be made to more carefully investigate the oxidation of FeCo and its alloys utilizing nanoparticles, and thin films with (100), (110), and (211) texture to observe the kinetics of oxidation. Thin film epitaxial relationships between the substrate and thin films have been determined, and this will be extended to the oxide and thin film. The role of alloying has been discussed, especially in the context of oxidation of FeCo. The composition of the oxide at different oxidizing temperatures is also proposed. FeCo-based nanoparticles have been analyzed to understand their change in magnetization and oxide phase as a function of temperature. The oxide thickness has been measured at various temperatures, along with the observation of a voided core. This research has been coupled with thin film work to show that the core gets richer in cobalt as oxidation progresses, with Fe acting as the mobile species. Oxygen may diffuse early in the oxidation, but only until a certain oxide thickness has been established. The oxidation kinetics seen in the nanoparticles is slower than that seen in thin films, and it has currently been analyzed to follow a logarithmic rate law at lower temperatures. To understand the formation of faceted nanoparticles, nucleation and growth has been modeled for both BCC and FCC systems showing the surface energy ratios necessary to produce different faceting of nanoparticles. It has been shown that the critical nuclei are the same as the growth shapes. To extend the basic science research into the applications field, thin film work on CoCrPt has been performed to achieve out-of-plane anisotropy in thicker films for use in a portable AGFM. While this has been achieved, further study is necessary to improve the remnant magnetization and make it more comparable to SmCo, which is the current standard. The magnetic properties have been measured as a function of temperature and film thickness to begin understanding the system better to produce the desired thin film properties for a biomedical sensor.

description: We describe an electro-optical switch based on a commercial electro-optic modulator (modified for high-speed operation) and a 340V pulser having a rise time of 2.2ns (at 250V). It can produce arbitrary pulse patterns with an average repetition rate beyond 20MHz. It uses a grounded-grid triode driven by transmitting power transistors. We discuss variations that enable analog operation, use the step-recovery effect in bipolar transistors, or offer other combinations of output voltage, size, and cost.
