description: Bekannte Verfahren zur Berechnung stochastischer Darstellungen des Gradienten von Wärmeleitungs- oder allgemeiner Diffusionshalbgruppen auf Riemannschen Mannigfaltigkeiten mittels Martingalmethoden werden in dieser Arbeit auf den Fall zweiter Ableitungen ausgedehnt. Wir erhalten zunächst nicht-intrinsische Darstellungsformeln in 'Bismut-Form' für die Hessesche von harmonischen Funktionen oder Diffusionshalbgruppen. Diese verallgemeinern ein Resultat von Elworthy und Li (1994). Durch Anwendung einer Vertauschungsrelation von Arnaudon und Thalmaier (2002) für das stochastische und das covariante Differential des Dohrn-Guerra-Transports längs der Pfade einer Brownschen Bewegung auf der Mannigfaltigkeit wird es möglich, durch 'Herausfiltern überflüssigen Rauschens' zu einer intrinsischen Version zu gelangen, d.h. einer Darstellung, deren Einträge nurmehr von Krümmungsgrößen der Mannigfaltigkeit und der treibenden Diffusion selbst, nicht aber von den Koeffizienten der zugehörigen stochastischen Differentialgleichung abhängen. Als Anwendungen werden Gradientenabschätzungen von Thalmaier und Wang auf den Fall der Hesseform übertragen. Darüberhinaus wird gezeigt, wie im Falle einer rotationssymmetrischen Mannigfaltigkeit die Abschätzungen verbessert werden können.
description: In this thesis we extend well-known procedures using martingale methods to derive stochastic representations of the gradient of heat (or, more generally, diffusion) semigroups on Riemannian manifolds to the case of second derivatives. We first obtain non-intrinsic representation formulae of 'Bismut type' for the Hessian of harmonic functions or diffusion semigroups. This generalizes an earlier result of Elworthy and Li from 1994. Applying a commutation formula (Arnaudon and Thalmaier, 2002) for the stochastic and the covariant differentials of the Dohrn Guerra transport along the paths of a Brownian motion on the manifold, we are able to obtain an intrinsic version by 'filtering out redundant noise'. This means we are given a representation that depends on curvature expressions and the driving diffusion itself, but not on the coefficients of the related stochastic differential equation. As first applications, we transfer gradient estimates of Thalmaier and Wang to the case of the Hessian. Moreover, we give a method to derive better estimates if the manifold is rotationally symmetric.

description: The brane world description of our universe entails a large extra dimension and a fundamental scale of gravity that may be lower than the Planck scale by several orders of magnitude. An interesting consequence of this scenario occurs in the nature of spherically-symmetric vacuum solutions to the brane gravitational field equations, which often have properties quite distinct from the standard black hole solutions of general relativity. In this paper, the spherically-symmetric collapse on the brane world of four types of null fluid, governed by the barotropic, polytropic, strange quark "bag" model and Hagedorn equations of state, is investigated. In each case, we solve the approximate gravitational field equations, obtained in the high density limit, determine the equation which governs the formation of apparent horizons and investigate the conditions for the formation of naked singularities. Though, naively, one would expect the increased effective energy density on the brane to favor the formation of black holes over naked singularities, we find that, for the types of fluid considered, this is not the case. However, the black hole solutions differ substantially from their general-relativistic counterparts and brane world corrections often play a role analogous to charge in general relativity. As a possible astrophysical application of this work, the possibility that energy emission from a Hagedorn fluid collapsing to form a naked singularity may be a source of GRBs in the brane world is also considered.

description: There are groups of mites that establish biological interactions with other invertebrates, however, the studies are restricted to specific taxonomic groups and to some geographic regions. In Mexico, associations between some families of insects and mites have been recorded. Within these interactions there is «phoresy»; a dynamic and temporal relationship in which an organism actively seeks and attaches itself to another animal in order to disperse. Moreover, «parasitism» is an association in which one organism is negatively affected by the presence of another. The current study analyzes both interactions with specimens from entomological collections. The mites' attachment spots were determined, photographs were taken and subsequently a sample of mites was removed and prepared for identification. A total of 76 mites were obtained from ten species of insects. In the case of strict phoresis: Uropoda orbicularis Müller, 1776 (Mesostigmata) and Dendrolaelaps sp. (Mesostigmata: Digamasellidae) were recorded in six species of Cerambycidae (Coleoptera) and Proctolaelaps sp. (Mesostigmata: Ascidae) was found in Heliconius erato cyrbia (Lepidoptera: Nymphalidae). Regarding protelean parasitism: Leptus nr. californicus (Erythraeidae) was found in Photinus bucaro Zaragoza, 2005 (Coleoptera: Lampyridae) and Leptus nr. phyllotretae; nr. albertensis were found in Ithomiinae and Satyrinae (Lepidoptera) respectively. The most frequent spots where mites attach were the legs and the mesothorax. Only Uropodidae mites develop specialized structures (pedicels) for phoretic dispersion. These findings are registered for the first time in the aforementioned taxa for our country and highlight the need to continue with interdisciplinary studies to analyze these phenomena in order to glimpse the rules and processes that govern these associations. This will allow a better understanding of the mechanisms of succession and the possible evolutionary implications.
Self-similar solutions for a fractional thin film equation governing hydraulic fractures

description: In this paper, self-similar solutions for a fractional thin film equation governing hydraulic fractures are constructed. One of the boundary conditions, which accounts for the energy required to break the rock, involves the toughness coefficient $K\geq 0$. Mathematically, this condition plays the same role as the contact angle condition in the thin film equation. We consider two situations: The zero toughness ($K=0$) and the finite toughness $K\in(0,\infty)$ cases. In the first case, we prove the existence of self-similar solutions with constant mass. In the second case, we prove that for all $K\textgreater{}0$ there exists an injection rate for the fluid such that self-similar solutions exist.

We consider Lévy and additive process with respect to generalized and weak generalized convolutions as certain Markov processes, and then study stochastic integrals with respect to such processes. We introduce the representability property of weak generalized convolutions. Under this property and the related weak summability, a stochastic integral with respect to random measures related to such convolutions is constructed.

The meromorphic correlators of the chiral algebra compute correlators in a protected sector of the four-dimensional theory. Infinite chiral symmetry has far-reaching consequences for the spectral data, correlation functions, and central charges of any four-dimensional theory with ${\mathcal N}=2$ superconformal symmetry.

description: The early 21st century witnesses a dramatic rise in the study of thermal radiation of neutron stars. Modern space telescopes have provided a wealth of valuable information which, when properly interpreted, can elucidate the physics of superdense matter in the interior of these stars. This interpretation is necessarily based on the theory of formation of neutron star thermal spectra, which, in turn, is based on plasma physics and on the understanding of radiative processes in stellar photospheres. In this paper, the current status of the theory is reviewed with particular emphasis on neutron stars with strong magnetic fields. In addition to the conventional deep (semi-infinite) atmospheres, radiative condensed surfaces of neutron stars and "thin" (finite) atmospheres are considered.

description: We establish the following splitter theorem for graphs and its generalization for matroids: Let $G$ and $H$ be $3$-connected simple graphs such that $G$ has an $H$-minor and $k:=|V(G)|-|V(H)|\ge 2$. Let $n:=\left\lceil k/2\right\rceil+1$. Then there are pairwise disjoint sets $X_1,\dots,X_n\subseteq E(G)$ such that each $G/X_i$ is a $3$-connected graph with an $H$-minor, each $X_i$ is a singleton set or the edge set of a triangle of $G$ with $3$ degree-$3$ vertices and $X_1\cup\cdots\cup X_n$ contains no edge sets of circuits of $G$ other than the $X_i$'s. This result extends previous ones of Whittle (for $k=1,2$) and Costalonga (for $k=3$).

Zunächst werden die verwendeten Methoden eingeführt. Danach werden folgenden Fragestellungen untersucht: 1) The Lokalisierung und Chrialität der niedigliegenden Eigenmoden des chiral verbesserten Gitter Dirac Operators auf beiden Seiten des Phasenübergangs: Wir untersuchen das Yang-Mills Vakuum mit Hilfe der niedrigliegenden Eigenmoden des Gitter Dirac Operators. Wir zeigen, dass diese Moden von lokalisierten, chiralen Strukturen dominiert sind. Unterhalb des Phasenübergangs sind diese ausreichend vorhanden, um das chirale Kondensat zu erzeugen. 2) Das Spektrum der leichten Hadronen mit dem chiral verbesserten Dirac Operator: Die Massen der leichten Hadronen werden berechnet, um die chiralen Eigenschaften, das Skalenverhalten und die Disperionsrelationen des chiral verbesserten Dirac Operators zu testen. 3) Momente von Strukturfunktionen: Es werden die Erwartungswerte von Vier-Quark Operatoren im Proton berechnet. Diese können mit Momenten von Strukturfunktionen höheren Twists in Verbindung gebracht werden. Zuletzt präsentieren wir Ergebnisse zu Momenten der polarisierten und unpolarisierten Strukturfunktionen zu führendem Twist im Lambda Hyperon.
description: In this thesis, results from various calculations in quenched lattice quantum chromodynamics are presented. First, an introduction into the general methods is given. After that, the following topics are investigated: 1) The localalization and chirality of the low lying eigenmodes of the chirally improved lattice QCD Dirac operator on both sides of the phase transition: We examine the structure of the Yang-Mills vaccuum by looking at the low lying eigenmodes of the lattice Dirac operator. We show that these modes are dominated by localized, chiral structures. Below the phase transition, these excitations are sufficiently abundant to build up a chiral condensate. 2) The light hadronic spectrum of the chirally improved Dirac operator: The masses of the light hadrons are computed in order to test the chiral properties and the scaling behavior of the chirally improved Dirac operator along with the dispersion relations. 3) The moments of hadronic structure functions: First, the expectation value of four-quark operators inside the proton are computed. These can be connected to moments of baryonic higher twist structure functions. Finally, we present results for the first moments of the polarized and unpolarized leading twist structure functions of the Lambda hyperon.
New mechanism for Type-II seesaw dominance in SO(10) with low-mass Z-prime, RH neutrinos, and verifiable LFV, LNV, and proton decay

description: Dominance of type-II seesaw mechanism for neutrino masses has attracted considerable attention because of a number of advantages. We show a novel approach to achieve Type-II seesaw dominance in non-supersymmetric $SO(10)$ grand unification where a low mass $Z^{\prime}$ boson and specific patterns of right-handed neutrino masses are predicted within the accessible energy range of the Large Hadron Collider. In spite of the high value of the seesaw scale, $M_{Δ_L} \simeq 10^8-10^9$ GeV, the model predicts new dominant contributions to neutrino-less double beta decay in the $W_L-W_L$ channel close to the current experimental limits via exchanges of heavier singlet fermions used as essential ingredients of this model even when the light active neutrino masses are normally hierarchical or invertedly hierarchical. We obtain upper bounds on the lightest sterile neutrino mass $m_s\lesssim 3.0$ GeV, $2.0$ GeV, and $0.7$ GeV for normally hierarchical, invertedly hierarchical, and quasi-degenerate patterns of light neutrino masses, respectively. The underlying non-unitarity effects lead to lepton flavor violating decay branching ratios within the reach of ongoing or planned experiments and the leptonic CP-violation parameter nearly two orders larger than the quark sector. Some of the predicted values on proton lifetime for $p\to e^+π^0$ are found to be within the currently accessible search limits. Other aspects of model applications including leptogenesis etc. are briefly indicated.

description: Density regression provides a flexible strategy for modeling the distribution of a response variable $Y$ given predictors $\mathbf{X}=(X_1,\ldots,X_p)$ by letting that the conditional density of $Y$ given $\mathbf{X}$ as a completely unknown function and allowing its shape to change with the value of $\mathbf{X}$. The number of predictors $p$ may be very large, possibly much larger than the number of observations $n$, but the conditional density is assumed to depend only on a much smaller number of predictors, which are unknown. In addition to estimation, the goal is also to select the important predictors which actually affect the true conditional density. We consider a nonparametric Bayesian approach to density regression by constructing a random series prior based on tensor products of spline functions. The proposed prior also incorporates the issue of variable selection. We show that the posterior distribution of the conditional density contracts adaptively at the truth nearly at the optimal oracle rate, determined by the unknown sparsity and smoothness levels, even in the ultra high-dimensional settings where $p$ increases exponentially with $n$. The result is also extended to the anisotropic case where the degree of smoothness can vary in different directions, and both random and deterministic predictors are considered. We also propose a technique to calculate posterior moments of the conditional density function without requiring Markov chain Monte Carlo methods.

description: The asymptotic behavior of the first eigenvalues of magnetic Laplacian operators with large magnetic fields and Neumann realization in smooth three-dimensional domains is characterized by model problems inside the domain or on its boundary. In two-dimensional polygonal domains, a new set of model problems on sectors has to be taken into account. In this paper, we consider the class of general corner domains. In dimension 3, they include as particular cases polyhedra and axisymmetric cones. We attach model problems not only to each point of the closure of the domain, but also to a hierarchy of "tangent substructures" associated with singular chains. We investigate properties of these model problems, namely continuity, semi-continuity, existence of generalized eigenfunctions satisfying exponential decay. We prove estimates for the remainders of our asymptotic formula. Lower bounds are obtained with the help of an IMS partition based on adequate two-scale coverings of the corner domain, whereas upper bounds are established by a novel construction of quasimodes, qualified as sitting or sliding according to spectral properties of local model problems. A part of our analysis extends to any dimension.

description: We consider locally equi-continuous strongly continuous semigroups on locally convex spaces (X,tau). First, we show that if (X,tau) has the property that weak* compact sets of the dual are equi-continuous, then strong continuity of the semigroup is equivalent to weak continuity and local equi-continuity. Second, we consider locally convex spaces (X,tau) that are also equipped with a `suitable' auxiliary norm. We introduce the set N of tau continuous semi-norms that are bounded by the norm. If (X,tau) has the property that N is closed under countable convex combinations, then a number of Banach space results can be generalised in a straightforward way. Importantly, we extend the Hille-Yosida theorem. We apply the results to the study of transition semigroups of Markov processes on complete separable metric spaces.

Derivatives of Parsing Expression Grammars

Subjects: subject: Formal Languages and Automata Theory (cs.FL)

description: This paper introduces a new derivative parsing algorithm for recognition of parsing expression grammars. Derivative parsing is shown to have a polynomial worst-case time bound, an improvement on the exponential bound of the recursive descent algorithm. This work also introduces asymptotic analysis based on inputs with a constant bound on both grammar nesting depth and number of backtracking choices; derivative and recursive descent parsing are shown to run in linear time and constant space on this useful class of inputs, with both the theoretical bounds and the reasonability of the input class validated empirically. This common-case constant memory usage of derivative parsing is an improvement on the linear space required by the packrat algorithm.

description: Electric field effect (EFE) controlled magnetoelectric transport in thin films of undoped and La-doped Sr$_{2}$IrO$_{4}$ (SIO) were investigated under the action of ionic liquid gating. Despite large carrier density modulation, the temperature dependent resistance measurements exhibit insulating behavior in chemically and EFE doped samples with the band filling up to 10\%. The ambipolar transport across the Mott gap is demonstrated by EFE tuning of the activation energy. Further, we observe a crossover from a negative magnetoresistance (MR) at high temperatures to positive MR at low temperatures. The crossover temperature was around $\sim$80-90 K, irrespective of the filling. This temperature and magnetic field dependent crossover is qualitatively associated with a change in the conduction mechanism from Mott to Coulomb gap mediated variable range hopping (VRH). This explains the origin of robust insulating ground state of SIO in electrical transport studies and highlights the importance of disorder and Coulombic interaction on electrical properties of SIO.

Proposal: Expert Iteration for Machine Learning Based Theorem Provers via Complexity Minimization

description:     We present a research proposal for employing position evaluators to improve tactic prediction in theorem proving. We propose to train a position evaluator to predict proof length, using this to effectively train a tactic predictor to select tactics that result in shorter proofs, and thus, enhance the tactic selection process. 
    Additionally, we conjecture that position evaluators can be utilized to guide proof search. We will evaluate our models using the CoqGym dataset. 
    We plan to do this with continual learning as via expert iteration, refining the model's performance over time and data set.
    In this context, we propose to view Expert Iteration as alternating maximization and a meta-learning algorithm.
title: Fremdsprachenlernen und Alter: haben ältere Fremdsprachenlernende Vorteile?
Creators: name: Müllner, Carina

description: Das Lernen von Fremdsprachen gewinnt aufgrund fortschreitender Globalisierung und des immer höheren Bildungsstandes der Österreicher:innen mehr und mehr an Bedeutung. Aber wann ist der „beste“ Zeitpunkt, eine Fremdsprache zu lernen? Weit verbreitet ist die Annahme, dass das Lernen von Sprachen sich mit fortschreitendem Alter immer schwieriger gestalte. Lange galt das Credo „Je früher, desto besser!“, wenn es um den Fremdsprachenerwerb ging. Aber so eindeutig lässt sich hier keine Aussage treffen. Das Ziel der vorliegenden Forschungsarbeit ist es, die Vorteile von erwachsenen Fremdsprachenlernenden ab einem Alter von 48 Jahren aufzuzeigen. Dies geschieht durch eine Gegenüberstellung mit jugendlichen Fremdsprachenlernenden. Genauer in den Blick genommen werden soziale, körperliche und kognitive Faktoren in diesen beiden Lebensphasen. Die Ergebnisse der Erhebung sollen der Sensibilisierung für diese immer größer und wichtiger werdende Gruppe an älteren Fremdsprachenlernenden dienen und in weiterer Folge Anstoß für die Entwicklung didaktischer Konzepte sein, welche auf die Bedürfnisse dieser Zielgruppe abgestimmt sind.

description: In this paper, we address the problem of reconstructing coverage maps from path-loss measurements in cellular networks. We propose and evaluate two kernel-based adaptive online algorithms as an alternative to typical offline methods. The proposed algorithms are application-tailored extensions of powerful iterative methods such as the adaptive projected subgradient method and a state-of-the-art adaptive multikernel method. Assuming that the moving trajectories of users are available, it is shown how side information can be incorporated in the algorithms to improve their convergence performance and the quality of the estimation. The complexity is significantly reduced by imposing sparsity-awareness in the sense that the algorithms exploit the compressibility of the measurement data to reduce the amount of data which is saved and processed. Finally, we present extensive simulations based on realistic data to show that our algorithms provide fast, robust estimates of coverage maps in real-world scenarios. Envisioned applications include path-loss prediction along trajectories of mobile users as a building block for anticipatory buffering or traffic offloading.

description: To an algebraic variety equipped with an involution, we associate a cycle class in the modulo two Chow group of its fixed locus. This association is functorial with respect to proper morphisms having a degree and preserving the involutions. Specialising to the exchange involution of the square of a complete variety, we obtain Rost's degree formula in arbitrary characteristic (this formula was proved by Rost/Merkurjev in characteristic not two).

description: Introduction of the domestic cat and red fox has devastated Australian native fauna. We synthesized Australian diet analyses to identify traits of prey species in cat, fox and dingo diets, which prey were more frequent or distinctive to the diet of each predator, and quantified dietary overlap. Nearly half (45%) of all Australian terrestrial mammal, bird and reptile species occurred in the diets of one or more predators. Cat and dingo diets overlapped least (0.64 ± 0.27, n = 24 location/time points) and cat diet changed little over 55 years of study. Cats were more likely to have eaten birds, reptiles and small mammals than foxes or dingoes. Dingo diet remained constant over 53 years and constituted the largest mammal, bird and reptile prey species, including more macropods/potoroids, wombats, monotremes and bandicoots/bilbies than cats or foxes. Fox diet had greater overlap with both cats (0.79 ± 0.20, n = 37) and dingoes (0.73 ± 0.21, n = 42), fewer distinctive items (plant material, possums/gliders) and significant spatial and temporal heterogeneity over 69 years, suggesting the opportunity for prey switching (especially of mammal prey) to mitigate competition. Our study reinforced concerns about mesopredator impacts upon scarce/threatened species and the need to control foxes and cats for fauna conservation. However, extensive dietary overlap and opportunism, as well as low incidence of mesopredators in dingo diets, precluded resolution of the debate about possible dingo suppression of foxes and cats.
A geometric study of Wasserstein spaces: isometric rigidity in negative curvature

description: Given a metric space X, one defines its Wasserstein space W2(X) as a set of sufficiently decaying probability measures on X endowed with a metric defined from optimal transportation. In this article, we continue the geometric study of W2(X) when X is a simply connected, nonpositively curved metric spaces by considering its isometry group. When X is Euclidean, the second named author proved that this isometry group is larger than the isometry group of X. In contrast, we prove here a rigidity result: when X is negatively curved, any isometry of W2(X) comes from an isometry of X.

description: We find conditions which guarantee moment (in)determinacy of powers and products of nonnegative random variables. We establish new and general results which are based either on the rate of growth of the moments of a random variable or on conditions about the distribution itself. For the class of generalized gamma random variables we show that the power and the product of such variables share the same moment determinacy property. A similar statement holds for half-logistic random variables. Besides answering new questions in this area, we either extend some previously known results or provide new and transparent proofs of existing results.

description: We report on the possibility to use dark matter particle's mass and its cross section as a smoking gun signal of the existence of a Big Bounce at the early stage in the evolution of our currently observed universe. A model independent study of dark matter production in the pre-bounce contraction and the post-bounce expansion epochs of the bounce universe reveals a new venue for achieving the observed relic abundance of our present universe, in which a significantly smaller amount of dark matter with a smaller cross section -- as compared to the prediction of Standard Cosmology -- is produced and carries the information about the bounce universe evolution. Once the values of dark matter mass and cross section are obtained by direct detection in laboratories, this alternative route becomes a signature of the bounce universe scenario.
