description: For an evolution of metrics $(M,g_{t})$ there is a t-smooth family of embeddings $e_{t}:M\to\mathbb{R}^{N}$ inducing $g_{t}$, but in general there is no family of embeddings extending a given initial embedding $e_{0}$. We give an example of this phenomenon when $g_{t}$ is the evolution of $g_{0}$ under the Ricci flow. We show that there are embeddings $e_{0}$ inducing $g_{0}$ which do not admit of t-smooth extensions to $e_{t}$ inducing $g_{t}$ for any t>0. We also find hypersurfaces of dim>2 that will not remain a hypersurface under Ricci flow for any positive time.

description: Cryptographic random number generation is critical for any quantum safe encryption. Based on the natural uncertainty of some quantum processes, variety of quantum random number generators or QRNGs have been created with physical quantum processes. They generally generate random numbers with good unpredictable randomness. Of course, physical QRNGs are costic and require physical integrations with computing systems. This paper proposes a pseudo quantum random number generator with a quantum algorithm called quantum permutation pad or QPP, leveraging the high entropy of quantum permutation space its bijective transformation. Unlike the Boolean algebra where the size of information space is 2n for an n-bit system, an n-bit quantum permutation space consists of 2n! quantum permutation matrices, representing all quantum permutation gates over an n-bit computational basis. This permutation space holds an equivalent Shannon information entropy log_2(2^n!). A QPP can be used to create a pseudo QRNG or pQRNG capable integrated with any classical computing system or directly with any application for good quality deterministic random number generation. Using a QPP pad with 64 8-bit permuation matrices, pQRNG holds 107,776 bits of entropy for the pseudo random number generation, comparing with 4096 bits of entropy in Linux /dev/random. It can be used as a deterministic PRNG or entropy booster of other PRNGs. It can also be used as a whitening algorithm for any hardware random number generator including QRNG without discarding physical bias bits.

description: This article gives explicit integral formulas for the so-called generalized metaplectic operators, i.e. Fourier integral operators (FIOs) of Schrödinger type, having a symplectic matrix as canonical transformation. These integrals are over specific linear subspaces of R^d, related to the d x d upper left-hand side submatrix of the underlying 2d x 2d symplectic matrix. The arguments use the integral representations for the classical metaplectic operators obtained by Morsche and Oonincx in a previous paper, algebraic properties of symplectic matrices and time-frequency tools. As an application, we give a specific integral representation for solutions to the Cauchy problem of Schrödinger equations with bounded perturbations for every instant time t in R, even in the so-called caustic points.

title: Deliberative und partizipative Demokratietheorie im Feld der Digitalität
Creators: name: Wissinger, Katia Frida Antonia
Year: 2022

description: Im Zentrum dieser Arbeit steht die Frage, wie die wachsende Digitalität unserer Gesellschaft aus einer demokratietheoretischen Perspektive interpretiert und bewertet werden soll. Insofern der Zuwachs an neuen Technologien der Vernetzung und des Wissensaustausches es vermehrt ermöglicht, sich auf eine informierte Weise an Debatten und Entscheidungen des Gemeinwesens zu beteiligen, wird die Hypothese geprüft, ob damit das Fundament für eine bessere Demokratie gelegt wird. Ausgehend von der deliberativen und der partizipativen Demokratietheorie, die beide die Beteiligung der politischen Subjekte an der Demokratie in den Fokus rücken, werden ausgewählte Phänomene der Digitalität analysiert, wie etwa die öffentliche Meinungsbildung im Netz oder digitale Beteiligungsverfahren. Beide Theorien bieten wichtige konzeptuelle Ansätze, um besser zu verstehen, wie wir als politische Subjekte im digitalen Zeitalter kommunizieren und handeln. Zugleich zeigen sie die Grenzen von digital gestützten Formen der Meinungsbildung und Entscheidungsfindung auf: strukturelle Ungleichheiten im Zugang, mitunter schwache epistemische Anforderungen, mangelnde Effizienz und, in manchen Fällen, ein Defizit an demokratischer Grundhaltung.
description: This study discusses how the increased digitality of our societies should be interpreted and evaluated from the perspective of democratic theory. As new networking and knowledge-sharing technologies allow more frequent and better-informed forms of participating in public debates and decisions, I will test the assumption that these technologies lay the foundation for a better democracy. Drawing on deliberative and participatory democratic theory, I analyze selected phenomena of digital culture, such as online public opinion formation and digital participatory formats. Both theories offer important conceptual approaches to better understand how we communicate and act as political subjects in the digital age. At the same time, they highlight the limits of digitally supported forms of opinion-forming and decision-making: among these I will particularly assess the structural inequalities in access, low epistemic standards, lack of efficiency, and, in some cases, environments that structurally prevent subjects from adopting basic democratic attitudes.

description: We report on the realization of an array of 28 × 28 mesas with site-controlled InGaAs quantum dots acting as single-photon sources for potential applications in photonic quantum technology. The site-selective growth of quantum dots is achieved by using the buried stressor approach where an oxide aperture serves as the nucleation site in the center of each mesa. Spectroscopic maps demonstrate the positioning of quantum dots with an inhomogeneous broadening of the ensemble emission of only 15.8 meV. Individual quantum dots are characterized by clean single-quantum-dot spectra with narrow exciton, biexciton, and trion lines, with a best value of 27 μeV and an ensemble average of 120 μeV. Beyond that, Hanbury Brown and Twiss and Hong-Ou-Mandel measurements validate the quantum nature of emission in terms of high single-photon purity and photon indistinguishability with a g(2)(0) value of (0.026 ± 0.026) and a post-selected two-photon interference visibility V = (87.1 ± 9.7)% with an associated coherence time of τc = (194 ± 7) ps.

description: Metformin (METF), historical antihyperglycemic drug, is a likely candidate for lifespan extension, treatment and prevention of sedentariness damages, insulin resistance and obesity. Skeletal muscle is a highly adaptable tissue, capable to increase its mass in response to exercise and to regenerate new fibrils after damage. Aims of this work were to investigate METF ability to prevent sedentariness injury and enhance skeletal muscle function. Sedentary 12-weeks old C57BL/6 mice were treated with METF (250 mg/kg per day, in drinking water) for 60 days. METF role on skeletal muscle differentiation was studied in vitro using murine C2C12 myoblasts. Muscular performance evaluation revealed that METF enhanced mice physical performance. Tissues analysis indicated that in liver METF increased AMPK and CAMKII signaling, while inactivated ERKs, principal kinases involved in hepatic stress conditions. In skeletal muscle, METF activated AKT, key kinase in skeletal muscle maintenance. In in vitro studies, Immunofluorescence and Western blot analysis showed that METF did not modify the C2C12 proliferation capacity, while positively influenced the differentiation process and myotube maturation. Together, our novel results suggest that METF may have a positive action not only on the promotion of healthy aging but also on the prevention of sedentariness damages.?

We prove that for each such tree $\mathcal{T}$, the Calkin algebra of $X_{\mathcal{T}}$ is homomorphic to $C(\mathcal{T})$, the algebra of continuous functions defined on $\mathcal{T}$, equipped with the usual topology. We use this fact to conclude that for every countable compact metric space $K$ there exists a $\mathcal{L}_\infty$-space whose Calkin algebra is isomorphic, as a Banach algebra, to $C(K)$.

description: Using the low-energy effective Hamiltonian of the ABC-stacked multilayer graphene, pseudo spin coupling to real orbital angular momentum of electron in multilayer graphene is investigated. We show that electron wave function in N-layer graphene mimics behavior of particle with spin of N/2. It is said that for N greater than 1 the low-energy effective Hamiltonian for ABC-stacked graphene is no longer used to describe pseudo spin 1/2-particle wave function. The wave function of electron in multilayer graphene may behave like fermionic (or bosonic) particle when N is odd (or even). This work proposes a theory of graphene as a host material of electron with arbitrary pseudo spins, tunable by changing number of graphene layers.

The BRST Complex of Homological Poisson Reduction
Creators: name: Müller-Lennert, Martin
Publisher: name: arXiv
Year: 2014
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: BRST complexes are differential graded Poisson algebras. They are associated to a coisotropic ideal $J$ of a Poisson algebra $P$ and provide a description of the Poisson algebra $(P/J)^J$ as their cohomology in degree zero. Using the notion of stable equivalence introduced by Felder and Kazhdan, we prove that any two BRST complexes associated to the same coisotropic ideal are quasi-isomorphic in the case $P = \mathbb{R}[V]$ where $V$ is a finite-dimensional symplectic vector space and the bracket on $P$ is induced by the symplectic structure on $V$. As a corollary, the cohomology of the BRST complexes is canonically associated to the coisotropic ideal $J$ in the symplectic case. We do not require any regularity assumptions on the constraints generating the ideal $J$. We finally quantize the BRST complex rigorously in the presence of infinitely many ghost variables and discuss uniqueness of the quantization procedure.

description: An efficient process of emergency evacuation must be guided. In the event of an evacuation instruction, a significant amount of time is spent by evacuees looking for a place of relative safety or an exit. Due to the ensuing stress and confusion evacuees try to follow others, consequently, all the exits are not used effectively. Therefore, it is important to develop a route guidance map for the emergency. The focus of the map is to help both, the evacuees and the authorities to perform evacuation efficiently. This paper presents a route guidance map for pedestrians that aims an efficient evacuation in case of an emergency. An agent-based simulation framework is used for the simulation of various scenarios to prepare the guiding map. A real world case study of Sarojini Nagar, Delhi is presented to test the presented methodology. Eventually, several strategic recommendations are provided for improving safety of existing infrastructure.

description: Cellular senescence limits the proliferation of dysfunctional cells in response to diverse forms of cellular stress, playing essential roles in tumor suppression and tissue regeneration, while also contributing to age-related pathologies. Here, we used multidimensional profiling to define the temporal organization of the senescence transcriptional program, the transcription factor network topology that controls it and its underlying epigenome dynamics. We show that the senescence program is bookmarked epigenetically by AP1 transcription factors, which pioneer this cell fate transition by activating, licensing and decommissioning enhancers relevant to the senescence program, including the newly characterized classes of “de novo” and “remnant” enhancers. Functional studies informed by genome-wide analyses further underscored the instructive role of AP1-cJUN since its silencing partially resets the senescence clock to a past transcriptional state. Together, our findings identify dynamically regulated chromatin transitions critical for senescence commitment, thus defining promising targets for manipulating the senescence program for therapeutic benefit.

description: For each $n > 0$ there is a one complex parameter family of homeomorphisms of the circle consisting of linear fractional transformations `conjugated by $z \to z^n$'. We show that these families are free of relations, which determines the structure of `the group of homeomorphisms of finite type'. We also discuss a number of questions regarding factorization for more robust groups of homeomorphisms of the circle in terms of these basic building blocks, and the correspondence between smoothness properties of the homeomorphisms and decay properties of the parameters.

description: Superluminous supernovae (SLSNe) are very bright explosions that were only discovered recently and that show a preference for occurring in faint dwarf galaxies. Understanding why stellar evolution yields different types of stellar explosions in these environments is fundamental in order to both uncover the elusive progenitors of SLSNe and to study star formation in dwarf galaxies. In this paper, we present the first results of our project to study SUperluminous Supernova Host galaxIES, focusing on the sample for which we have obtained spectroscopy. We show that SLSNe-I and SLSNe-R (hydrogen-poor) often (~50% in our sample) occur in a class of galaxies that is known as Extreme Emission Line Galaxies (EELGs). The probability of this happening by chance is negligible and we therefore conclude that the extreme environmental conditions and the SLSN phenomenon are related. In contrast, SLSNe-II (hydrogen-rich) occur in more massive, more metal-rich galaxies with softer radiation fields. Therefore, if SLSNe-II constitute a uniform class, their progenitor systems are likely different from those of H-poor SLSNe. Gamma-ray bursts (GRBs) are, on average, not found in as extreme environments as H-poor SLSNe. We propose that H-poor SLSNe result from the very first stars exploding in a starburst, even earlier than GRBs. This might indicate a bottom-light initial mass function in these systems. SLSNe present a novel method of selecting candidate EELGs independent of their luminosity.

title: Elementare Denkarten
Creators: name: Ramsauer, Markus Elias
Year: 2022

description: Die vorliegende Arbeit widmet sich den ethno-psychologischen Arbeiten Richard Thurnwalds (1869-1954), der in den Jahren 1906-1909, bzw. 1913-1915 Feldforschung im Gebiet des damaligen Deutsch-Neuguineas betrieb. Es wird hierbei insbesondere das Konzept verschiedener Denkarten bei industrialisierten, bzw. nicht-industrialisierten Gesellschaften aufgegriffen. Letztere würden sich nach Thurnwald vor allem des konkreten Denkens bedienen; bedingt durch deren Form der Subsistenzwirtschaft, die eine abstrakte, zergliedernde Epistemologie nicht notwendig mache. Abstraktion als Notwendigkeit der wirtschaftlich-umweltlichen Praxis aufzufassen, ermöglicht es dem Ethnologen, indigene Wissensformen nicht zwangsläufig als inferior zu bewerten und deren potentielle Veränderlichkeit anzuerkennen. Außerdem erlaubt, wie anhand der Beiträge Thurnwalds zum Totemismus gezeigt wird, ein Fokus auf die Epistemologie es, die Unterscheidung Natur-Kultur nicht als menschliche Universalie zu definieren. Neben der Darstellung der Denkart, wird auf die für ihre Erfassung verwendete Methodik eingegangen, bevor in einem weiteren Schritt die Thurnwaldsche Ethnopsychologie in Dialog mit anderen kulturanthropologischen Ansätzen zu indigenem Wissen gebracht wird. Die Gegenüberstellung mit dem klassischen Evolutionismus, dem historisch-materialistischen Zugang Aleksandr Lurijas und Lev Vygotskys, der Ethno-Psychoanalyse und dem Poststrukturalismus Phillipe Descolas erlaubt es einerseits den „Einzelgänger“ Thurnwald im akademischen Feld zu verorten; andererseits wird dadurch sein epistemologischer Zugang weiter erschlossen. Im Rahmen einer Positionierung gegenüber dem Quellenmaterial wird verdeutlicht, dass dieses weniger als akkurate Repräsentation indigenen Wissens, sondern als Verarbeitung von -von repressiven Machtverhältnissen geprägten- Begegnungen mit dem Anderen aufgefasst wird. Die mannigfachen Verstrickungen der Ethnologie mit dem europäischen Kolonialismus werden anhand der Biographie Thurnwalds beleuchtet. Die vorliegende Arbeit stellt somit einen Versuch dar, sich historisch-kritisch mit früher ethnologischer Feldforschung auseinanderzusetzen, ohne ihr dadurch jeglichen erkenntnistheoretischen Mehrwert abzusprechen.

description: A Lie-Hamilton system is a nonautonomous system of first-order ordinary differential equations describing the integral curves of a $t$-dependent vector field taking values in a finite-dimensional real Lie algebra of Hamiltonian vector fields with respect to a Poisson structure. We provide new algebraic/geometric techniques to easily determine the properties of such Lie algebras on the plane, e.g., their associated Poisson bivectors. We study new and known Lie-Hamilton systems on $\mathbb{R}^2$ with physical, biological and mathematical applications. New results cover Cayley-Klein Riccati equations, the here defined planar diffusion Riccati systems, complex Bernoulli differential equations and projective Schrödinger equations. Constants of motion for planar Lie-Hamilton systems are explicitly obtained which, in turn, allow us to derive superposition rules through a coalgebra approach.

description: This paper presents a brief survey (in Chinese) on path planning and feedrate interpolation. Numerical control technology is widely employed in the modern manufacturing industry, and related research has been emphasized by academia and industry. The traditional process of numerical control technology is mainly composed of tool path planning and feedrate interpolation. To attain the machining of high speed and precision, several problems in tool path planning and feedrate interpolation are usually transformed into mathematical optimization models. To better undertake the research on the integrated design and optimization idea of tool path planning and feedrate interpolation, it is necessary to systematically review and drawn on the existing representative works. We will introduce the relevant methods and technical progress of tool path planning and feedrate interpolation in CNC machining successively, including tool path planning based on end milling, tool orientation optimization, G-code processing and corner transition, feedrate planning of parameter curves, and some new machining optimization methods proposed recently.

title: Nikolaus von Verdun und die Zeitmode
Creators: name: Holzer, Edith
Year: 2022

description: Nikolaus von Verdun orientierte sich beim Kostümbild auf dem Klosterneuburger Ambo an Gewandformen der Spätantike und entwickelte aus diesem Kostümbild einen Darstellungsstil für gefältelte Kleidung, der sich durch weich fallende und großzügig eingelegte Muldenfalten auszeichnet. In der Kunstgeschichte hat sich diese Darstellungsweise unter dem Begriff „Muldenfaltenstil“ etabliert. Die Beschreibung und Herleitung dieses Modebildes dient in der vorliegenden Arbeit als Sprungbrett zur Aufarbeitung der Forschungsfrage nach Motiven der Zeitmode, die Nikolaus von Verdun im Muldenfaltenstil zeigt. Diese Masterarbeit soll einen Beitrag zur weiteren Erforschung der Figurengewandung auf dem Klosterneuburger Altar leisten und Anregungen für zukünftige Untersuchungen geben, denn auf diesem Gebiet besteht noch erheblicher Forschungsbedarf. Die Zeitmode des ausgehenden 12. Jahrhunderts ist aufgrund ihrer Herstellungsweise – dem Zuschnitt und Zusammennähen von Einzelteilen – grundverschieden von antikisierenden Vestimenten, die aus langen Stoffbahnen bestehen und um den Körper drapiert wurden. Infolge dieser bekleidungstechnisch bedingten Umstände war es eine spannende Aufgabe, die Nikolaus’schen Gewandungen nach zeittypischen Motiven zu untersuchen und die im Muldenfaltenstil dargestellte Zeitmode auf dem Klosterneuburger Altar aufzuspüren. Neben dem Forschungszweig der Kunstgeschichte war es hilfreich das Wissen um historische Bekleidung, sowie textil- und bekleidungstechnische Erkenntnisse ebenfalls mit einzubeziehen. Diese Arbeit soll einen Beitrag dazu leisten, Kunst und Mode in ein spannendes Beziehungsverhältnis zu setzen und dabei die Kostümanalyse näher in den wissenschaftlichen Fokus zu rücken, zumal die Gewandgebung der Figuren bei der Betrachtung eines Kunstwerkes als Erstes wahrgenommen wird.

description: It has been suggested that the origins of cognitive modernity in the Middle/Upper Paleolithic following the appearance of anatomically modern humans was due to the onset of dual processing or contextual focus (CF), the ability to shift between different modes of thought: an explicit mode conducive to logical problem solving, and an implicit mode conducive to free-association and breaking out of a rut. Mathematical and computational models of CF supported this hypothesis, showing that CF is conducive to making creative connections by placing concepts in new contexts. This paper proposes that CF was made possible by mutation of the FOXP2 gene in the Paleolithic. FOXP2, once thought to be the 'language gene', turned out not to be uniquely associated with language. In its modern form FOXP2 enabled fine-tuning of the neurological mechanisms underlying the capacity to shift between processing modes by varying the size of the activated region of memory.

description: With the motivation to develop superconformal field theory on S^3, we introduce a 2n-extended supersphere S^{3|4n}, with n=1,2,..., as a homogeneous space of the three-dimensional Euclidean superconformal group OSp(2n|2,2) such that its bosonic body is S^3. Supertwistor and bi-supertwistor realizations of S^{3|4n} are derived. We study in detail the n=1 case, which is unique in the sense that the R-symmetry subgroup SO^*(2n) of the superconformal group is compact only for n=1. In particular, we show that the OSp(2|2,2) transformations preserve the chiral subspace of S^{3|4}. Several supercoset realizations of S^{3|4n} are presented. Harmonic/projective extensions of the supersphere by auxiliary bosonic fibre directions are sketched.

description: In the previous papers, Furuta, Yoshida and the author gave a definition of analytic index theory of Dirac-type operator on open manifolds by making use of some geometric structure on an open covering of the end of the open manifold and a perturbation of the Dirac-type operator. In this paper we show the cobordism invariance of the index, and as an application we show the well-definedness of the index with respect to the choice of the open covering.

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: Key experimental results on unveiling and studying properties of a multiphase state that arises in two-dimensional electron systems due to the interplay of interelectron interactions and disorder are reviewed. The review focuses on the experimental results obtained with high mobility Si-field effects structures (Si-MOS), in which the interaction effects at low carrier concentrations are most pronounced due to the strong e-e interactions, multi-valley spectrum, and the short-range character of the random potential. The reviewed effects of phase separation include features in transport, magnetotransport and thermodynamics. Consideration of a number of experimental results is supplemented with a brief review of their theoretical interpretation.

description: A full three-dimensional Finite-Difference Time-Domain (FDTD)-based toolkit is developed to simulate the whispering gallery modes of a microsphere in the vicinity of a dipole source. This provides a guide for experiments that rely on efficient coupling to the modes of microspheres. The resultant spectra are compared to those of analytic models used in the field. In contrast to the analytic models, the FDTD method is able to collect flux from a variety of possible collection regions, such as a disk-shaped region. The customizability of the technique allows one to consider a variety of mode excitation scenarios, which are particularly useful for investigating novel properties of optical resonators, and are valuable in assessing the viability of a resonator for biosensing.

description: This work addresses the computation of the propability of fermionic particle pair production in $(d+1)-$ dimensional noncommutative Moyal space. Using the Seiberg-Witten maps that establish relations between noncommutative and commutative field variables, to first order in the noncommutative parameter $θ$, we derive the probability density of vacuum-vacuum pair production of Dirac particles. The cases of constant electromagnetic, alternating time-dependent and space-dependent electric fields are considered and discussed.

description: We study a two-component nonlinear Schr{ö}dinger system with equal, repulsive cubic interactions and different dispersion coefficients in the two components. We consider states that have a dark solitary wave in one component. Treating it as a frozen one, we explore the possibility of the formation of bright-solitonic structures in the other component. We identify bifurcation points at which such states emerge in the bright component in the linear limit and explore their continuation into the nonlinear regime. An additional analytically tractable limit is found to be that of vanishing dispersion of the bright component. We numerically identify regimes of potential stability, not only of the single-peak ground state (the dark-bright soliton), but also of excited states with one or more zero crossings in the bright component. When the states are identified as unstable, direct numerical simulations are used to investigate the outcome of the instability development. Although our principal focus is on the homogeneous setting, we also briefly touch upon the counterintuitive impact of the potential presence of a parabolic trap on the states of interest.

description: In this paper, we present an intelligent Assistant for Robotic Therapy (iART), that provides robotic assistance during 3D trajectory tracking tasks. We propose a novel LSTM-based robot learning from demonstration (LfD) paradigm to mimic a therapist's assistance behavior. iART presents a trajectory agnostic LfD routine that can generalize learned behavior from a single trajectory to any 3D shape. Once the therapist's behavior has been learned, iART enables the patient to modify this behavior as per their preference. The system requires only a single demonstration of 2 minutes and exhibits a mean accuracy of 91.41% in predicting, and hence mimicking a therapist's assistance behavior. The system delivers stable assistance in realtime and successfully reproduces different types of assistance behaviors.

description: Ethical decision-making is an important but challenging aspect of the role of a clinical psychologist. Little research has been conducted concerning how clinical psychologists make ethical decisions, with even less known about how trainees manage the process during professional training. The current study aimed to examine how trainees make ethical decisions, and how this process differs between more and less experienced trainees. Thirty-nine trainee clinical psychologists were recruited from a total of 17 doctoral training programmes in the United Kingdom. The sample recruited was demographically similar to the training population. A cross-sectional design was used to examine differences between first year (n = 19) and third year (n = 20) trainees. An online version of The Defining Issues Test questionnaire (DIT-2, Rest et al., 1999) was used to measure level of sophistication of ethical development, and individual face to face or Skype repertory grid interviews examined the integration of trainees’ personal and professional ethical decision-making construct subsystems. The vast majority of trainees were found to adopt a sophisticated approach to ethical decision-making, with half of all ethical decisions made from within a postconventional schematic approach. However, a small minority operated from within schemata based on maintenance of societal norms or personal interests. A deterioration in sophistication of thinking was demonstrated for more experienced trainees. Less experienced trainees were found to rely comparatively more heavily on their personal construct subsystems than more experienced trainees and vice versa. Increased integration between the subsystems over the course of training was demonstrated. The study demonstrates support for an acculturation process occurring throughout training. Implications of this and ideas for future research are discussed.
