Beyond the Body: Yoga and Advaita in the Aparokṣānubhūti
Creators: name: Slatoff, Zoe
Publisher: name: Lancaster University
Year: 2022
Subjects: Yoga
Advaita

description: The Aparokṣānubhūti incorporates dualistic Yoga practice and philosophy into non-dual Vedānta. Yoga is presented as a purificatory practice, which helps to develop the discernment (viveka) required for the ultimate Advaitic realization of the equality of ātman and brahman. Although attributed to Śaṅkarācārya, the Aparokṣānubhūti was more likely written between the late fifteenth and mid-sixteenth century, on the early side of the Advaitic response to the growing popularity of haṭhayoga. The Aparokṣānubhūti is one of the earliest texts to mention rājayoga, teaching a unique fifteen-part path, which includes a redefined version of Patañjali’s eight auxiliaries, leading to samādhi and ultimately to immediate awareness of the self, as its title suggests. Its main commentary—the Dīpikā—attributed to the fourteenth-century Vidyāraṇya, though probably written a few centuries later, suggests haṭhayoga as a last resort and unusually equates it with the yoga of Patañjali. This incorporation of Yoga into Advaita occurs in the Aparokṣānubhūti through the widening definitions of key Advaitic terms such as nididhyāsana (contemplation) to include yogic practices. The reason given for this inclusivity is the need to address the prārabdha (ripe) karma of those who have not yet cognized brahman, though presumably with the greater intention of subverting the growing tradition of haṭhayoga into its domain. In this thesis I translate the entire Dīpikā and look at key verses in some of the other, more recent commentaries to understand how and why Yoga and Advaita have been integrated together over time. I contextualize this with respect to contemporaneous texts on haṭhayoga, as well as later syncretic texts such as the Yoga Upaniṣads, which incorporate Advaita and the Aparokṣānubhūti in their own way. I then briefly look at how this has manifested in modern yoga, where the teachings of Yoga, Sāṃkhya, and Vedānta have become inextricably intertwined.

description: Context. Images of spatially resolved astrophysical objects contain a wealth of morphological and dynamical information, and effective extraction of this information is of paramount importance for understanding the physics and evolution of these objects. Algorithms and methods employed presently for this purpose (such as, for instance, Gaussian model fitting) often use simplified approaches for describing the structure of resolved objects. Aims. Automated (unsupervised) methods for structure decomposition and tracking of structural patterns are needed for this purpose, in order to be able to deal with the complexity of structure and large amount of data involved. Methods. A new Wavelet-based Image Segmentation and Evaluation (WISE) method is developed for multiscale decomposition, segmentation, and tracking of structural patterns in astronomical images. Results. The method is tested against simulated images of relativistic jets and applied to data from long-term monitoring of parsec- scale radio jets in 3C 273 and 3C 120. Working at its coarsest resolution, WISE reproduces exceptionally well the previous results of model fitting evaluation of the structure and kinematics in these jets. Extending the WISE structure analysis to the finer scales provides the first robust measurements of two-dimensional velocity fields in these jets and indicates that the velocity fields are likely to reflect the evolution of Kelvin-Hemlholtz instability developing the flow.

New analytic solution for the heat flow through a general harmonic network

Year: 2014

description: We present a new analytic expression for the heat current through a general harmonic network coupled with Ohmic reservoirs. We use a new method that enables us to express the stationary state of the network in terms of the eigenvectors and eigenvalues of a generalized cubic eigenvalue problem. In this way, we obtain exact formulae for the heat current and the local temperature inside the network. Our method does not rely in the usual assumptions of weak coupling to the environments or on the existence of an infinite cutoff in the environmental spectral densities. We use this method to study non-equilibrium processes without the weak coupling and Markovian approximations. As a first application of our method, we revisit the problem of heat conduction in 2D and 3D crystals with binary mass disorder. We complement previous results showing that for small systems the scaling of the heat current with the system size greatly depends on the strength of the interaction between system and reservoirs. This somewhat counter-intuitive result seems not to have been noticed before.

title: Persönlichkeitsmerkmale und Sportkletterperformance
Creators: name: Griessmair, Dietmar
Year: 2022

description: Ziel der vorliegenden Studie war es, besondere Persönlichkeitsmerkmale von Kletterern und Boulderern (indoor und outdoor) herauszufinden, die hohe Schwierigkeitsgrade bewältigen. Dafür wurden sowohl Mittelwertsvergleiche für Gruppen verschiedenen Kletterlevels durchgeführt, als auch die Korrelationen zwischen den Persönlichkeitsmerkmalen und dem Kletterlevel berechnet. Die Teilnehmer dieser als Querschnittsstudie angelegten Untersuchung waren Kletterer und/ oder Boulderer (N=185, MAlter=30.67, SD=8.79). Erhoben wurden die Persönlichkeitsmerkmale des Fünf Faktoren Modells (B5T®) und das Persönlichkeitsmerkmal Sensation Seeking (NISS). Ein Vergleich der Persönlichkeit von stärkeren Kletterern mit der Persönlichkeit von weniger starken Kletterern (in Bezug auf den höchsten jemals geschafften Klettergrad) ergab keinen signifikanten Unterschied für die Persönlichkeitsmerkmale Extraversion, Offenheit, Verträglichkeit, Gewissenhaftigkeit und Neurotizismus. Auch wurde keine signifikante Korrelation zwischen dem Klettergrad und diesen Big Five Persönlichkeitsmerkmalen gefunden. Für Sensation Seeking wurde für Fels-Boulderer sowie für Hallen-Seilkletterer ein signifikanter Unterschied zwischen stärkeren und weniger starken Kletterern gefunden: Stärkere Kletterer hatten im Mittel höhere Sensation Seeking Werte. Zudem korrelierte Sensation Seeking mit dem höchsten Klettergrad für Indoor-Seilkletterer (r=.21, p<.01) und Outdoor-Seilkletterer (r=17, p<.05).
description: The present study aimed at identifying special personality traits of climbers and boulderers (indoor and outdoor) who climb on a high level. For this purpose, mean value comparisons for groups of different climbing levels were carried out. In addition, correlations between personality traits and climbing level were calculated. The participants in this cross-sectional study were climbers and boulderers (N=185, MAge=30.67, SD=8.79). They completed questionnaires of the Five Factor Model (B5T®) and of Sensation Seeking (NISS). A comparison of personality between stronger and weaker climbers (in terms of the highest climbing grade achieved) showed no significant difference in the personality traits extraversion, openness, agreeableness, conscientiousness and neuroticism. Also, no significant correlation was found between climbing grade and the Big Five personality traits. Regarding sensation seeking, a significant difference was found between stronger and weaker outdoor boulderers. The same goes for indoor climbers. Stronger climbers had on average higher sensation seeking values in both cases. In addition, sensation seeking correlated with the highest climbing grade for indoor climbers (r=.21, p<.01) and outdoor climbers (r=17, p<.05).

description: We study a harmonically confined atomic gas which is subjected to an additional external potential such as an optical lattice. Using a linear response formulation, we determine the response of the gas to a small, time-dependent displacement of the harmonic trap and derive a simple exact relation showing that the centre-of-mass position of the atomic cloud is directly related to the global optical conductivity of the system. We demonstrate the usefulness of this approach by calculating the optical conductivity of bosonic atoms in an optical lattice. In the Mott insulating phase, there is clear evidence of an optical Mott gap, providing a proof-of-principle demonstration that the global optical conductivity gives high-quality information about the exci- tations of strongly-correlated quantum gases.

description: In the Higgs mechanism, mediators of the weak force acquire masses by interacting with the Higgs condensate, leading to a vector boson mass matrix. On the other hand, a rigid body accelerated through an inviscid, incompressible and irrotational fluid feels an opposing force linearly related to its acceleration, via an added-mass tensor. We uncover a striking physical analogy between the two effects and propose a dictionary relating them. The correspondence turns the gauge Lie algebra into the space of directions in which the body can move, encodes the pattern of gauge symmetry breaking in the shape of an associated body and relates symmetries of the body to those of the scalar vacuum manifold. The new viewpoint is illustrated with numerous examples, and raises interesting questions, notably on the fluid analogs of the broken symmetry and Higgs particle, and the field-theoretic analogue of the added mass of a composite body.

description: We present a theoretical analysis of surface-plasmon-mediated mode-coupling in a planar thin film metal/insulator stack. Solving for the modes of this structure, we obtain an avoided crossing in the angular domain that is tunable using the system's materials and geometrical parameters. The computed reflectance of the metal/insulator stack exhibits a lineshape that is modeled as a geometric Fano resonance, accompanied by a response function characteristic of an induced coherence, albeit in the angular domain. We also observe a reversal of the Fano lineshape asymmetry as the system's parameters are varied. We attribute this \emph{q}-reversal to an interloping background radiation field comprising the surface plasmon polariton mode.
Bounding quantum contextuality with lack of third-order intereference

description: Recently many simple principles have been proposed that can explain quantum limitations on possible sets of experimental probabilities in nonlocality and contextuality experiments. However, few implications between these principles are known. Here it is shown that lack of irreducible third-order interference (a generalisation of the idea that no probabilistic interference remains unaccounted for once we have taken into account interference between pairs of slits in a $n$-sit experiment) implies the principle known as the E principle or Consistent Exclusivity (that, if each pair of a set of experimental outcomes are exclusive alternatives in some measurement, then their probabilities are consistent with the existence of a further measurement in which they are all exclusive). This is a step towards a more unified understanding of quantum nonlocality and contextuality, which promises to allow derivations of important results from minimal, easily grasped assumptions. As one example, this result implies that lack of third order interference bounds violation of the CHSH-Bell inequality to 2.883.

In proving the theorem, we present a variant of the Campbell-Mecke theorem from stochastic geometry. We proceed to apply our result in the calculation of expected values involving interference in wireless Poisson networks. Based on this, we derive outage probabilities for transmissions in a Poisson network with Nakagami fading. Our results extend the stochastic geometry toolbox used for the mathematical analysis of interference-limited wireless networks.

description: For a closed surface S, the Hitchin component Hit_n(S) is a preferred component of the character variety consisting of group homomorphisms from the fundamental group pi_1(S) to the Lie group PSL_n(R). We construct a parametrization of the Hitchin component that is well-adapted to a maximal geodesic lamination on the surface. This is a natural extension of Thurston's parametrization of the Teichmueller space of S by shear coordinates associated to a maximal geodesic lamination, corresponding to the case n=2. However, significantly new ideas are needed in this higher dimensional case. The article concludes with a few applications.

description: Die vorliegende Masterarbeit gibt einen Überblick über die Baumaßnahmen und Ausstattungsgegenstände im alten Wiener Rathaus und der dazugehörigen Kapelle im 15. Jahrhundert. Dabei wurden Quellen zuerst systematisch gesammelt und in einem zweiten Schritt ausgewertet. Durch die kritische Analyse der Sekundärliteratur und das Heranziehen von historischem Kartenmaterial, Baubefunden, Planrissen und umwelthistorischer Quellen konnten einerseits ein Bau- und Ausstattungsprogramm mit Repräsentationsanspruch der Ratselite erkannt werden, andererseits auch neue Erkenntnisse bezüglich Zuschreibung, Datierung und Lokalisierung der besprochenen Planrisse gewonnen werden. Die Basis der Masterarbeit sind die teilweise nur unvollständig erhaltenen Regesten der Kammeramtsrechnungen des 15. Jahrhunderts. Durch den Gewinn dieser Erkenntnisse wird ein neuer Beitrag zur interdisziplinären Forschung des alten Wiener Rathauses geschaffen.
description: The presented master thesis surveys constructional measures, furniture, and objects in the former Viennese city hall and the included chapel in the 15th century. The first step was to gather sources systematically and analyze these in a further step. By critical analysis of the secondary literature and the adduction of historical cartography, building records, blueprints, and environmental resources the author managed to identify a distinct program in building and equipment with a certain entitlement to representation by the city council’s elite, as well as new insights on attribution, dating and localization of said historical blueprints. The foundation of this thesis consists of the regestae of bills by the office of chamberlain of the 15th century. The profits of these insights are a new contribution to the interdisciplinary research of the historic city hall of Vienna.

description: We revisit the physics of electron gas bilayers in the quantum Hall regime [Nature, 432 (2004) 691; Science, 305 (2004) 950], where transport and tunneling measurements provided evidence of a superfluid phase being present in the system. Previously, this behavior was explained by the possible formation of a BEC of excitons in the half-filled electron bilayers, where empty states play the role of holes. We discuss the fundamental difficulties with this scenario, and propose an alternative approach based on a treatment of the system as a pseudospin magnet. We show that the experimentally observed tunneling peak can be linked to the XY ferromagnet (FM) to Ising antiferromagnet (AFM) phase transition of the S=1/2 XXZ pseudospin model, driven by the change in total electron density. This transition is accompanied by a qualitative change in the nature of the low energy spin wave dispersion from a gapless linear mode in the XY-FM phase to a gapped, quadratic mode in the Ising-AFM phase.

title: Exploring Versatile Glycosyltransferases From Microorganisms for Natural Product Biosynthesis
Creators: name: Ren, Jie
Publisher: name: Utah State University
Year: 2023

description: This dissertation is mainly focused on exploring versatile glycosyltransferases from different microorganisms with the purpose of biosynthesizing bioactive natural product glycosides through microbial fermentation. This engineered biosynthesis approach is environmentally friendly, safe, and efficient compared with plant extraction, chemical synthesis, and enzymatic synthesis. Additionally, we applied these characterized glycosyltransferases as efficient biocatalytic tools to produce novel glycosides to expand the chemical repertoire of nature. These novel compounds showed improved water solubility and some of them exhibited enhanced stability and biological activity, which laid the foundation for the development of new therapeutic agents.
In my dissertation research, I have discovered two versatile glycosyltransferases and utilized them to create novel glycosides of selected bioactive molecules. Firstly, I found that Beauveria bassiana ATCC 7159 and Streptomyces chromofuscus ATCC 49982 can glycosylate the anticancer agent 2'-hydroxyflavanone and antitubercular agent chlorflavonin into their glycosides, respectively. These two putative glycosyltransferases are both versatile enzymes. Specifically, B. bassiana ATCC 7159 can attach 4''-O-methyl-β-D-glucose to different hydroxy groups of 2'-hydroxyflavanone. Meanwhile, S. chromofuscus ATCC 49982 can append glucuronic acid to the 5-hydroxy group of chlorflavonin. Second, a highly flexible glucosyltransferase (BbGT) was identified from B. bassiana ATCC 7159. When purified to near homogeneity, BbGT can convert quercetin to five mono- and one di-glucosylated derivatives through an in vitro enzymatic reaction. Moreover, different quercetin glucosides, namely quercetin-7-O-β-D-glucopyranoside and quercetin-3-O-β-D-glucopyranoside, were respectively produced in engineered Escherichia coli and Saccharomyces cerevisiae harboring BbGT. A novel versatile microbial UDP-glucuronyltransferase (UGT) was then discovered and characterized from S. chromofuscus ATCC 49982. The UGT was expressed in E. coli and was capable of converting resveratrol into two glucuronides both in vitro and in vivo. Additionally, the UGT has a highly flexible substrate specificity and serves as an effective tool to prepare mono- or diglucuronides of various bioactive molecules. These two studies provide effective methods to produce valuable health-benefitting natural product glycosides by expressing these two versatile glycosyltransferases in different expression hosts. Finally, I used the two aforementioned biocatalytic tools together with other wild type strains to generate a series of novel glycosides of 2'-hydroxyflavone with improved water solubility and some of them displayed enhanced bioactivity. Thus, this dissertation research provides several effective biocatalysts that can be used for structural modification of polyphenolic compounds for enhanced water solubility and/or biological activities.

description: We study the electromagnetic properties of a metamaterial consisting of polarizable (nano)particles and a single graphene sheet placed at the interface between two dielectrics. We show that the particle's polarizability is renormalized because of the electromagnetic coupling to surface plasmons supported by graphene, which results in a dispersive behavior, different for the polarizability components corresponding to the induced dipole moment, parallel and perpendicular to the graphene sheet. In particular, this effect is predicted to take place for a metallic particle whose bare polarizability in the terahertz (THz) region is practically equal to the cube of its radius (times $4π\varepsilon_0$). This opens the possibility to excite surface plasmons in graphene and enhance its absorption in the THz range by simply using a monolayer of metallic particles randomly deposited on top of it, as we show by explicit calculations.

title: Das kunsthistorische Überblickswerk als Zeugnis der Durchsetzung der Abstrakten Kunst (1917-1977)
Creators: name: Kamencek, Teresa
Year: 2022

description: Abstrakte Werke waren zu Beginn des 20. Jahrhunderts für die Öffentlichkeit weitgehend sichtbar. Sie waren ausstellungs- und sammlungswürdig, und konnten daher von der Kunstgeschichte nicht übersehen werden. Doch die Aufmerksamkeit der Disziplin war kein Garant der Etablierung: Gegner sowie Befürworter schickten die Strömung durch alle Zustandsformen. Heute wissen wir, dass die Abstrakte Kunst eine der bekanntesten Kunstformen überhaupt ist. So stellt sich die Frage, wie und wann sie sich als eigenständige, großgeschriebene Kunstrichtung etablieren konnte. Die vorliegende Arbeit stellt erstmals die These auf, dass die Etablierung der Abstrakten Kunst vor allem anhand der Gattung der kunsthistorischen Standardliteratur nachzuvollziehen ist. In ihrer Funktion als kollektives Gedächtnis der Disziplin soll die Gattung als neuartiger Untersuchungsgegenstand vorgestellt und ihre Relevanz für die Durchsetzungsgeschichte der Abstrakten Kunst kritisch beleuchtet werden. Um zu zeigen, dass sich dieser Prozess anhand des Genres der kunsthistorischen Standardliteratur nachvollziehen lässt, wurde zunächst ein Korpus von sechzehn geeigneten Publikationen anhand ihrer Originalsprache (Deutsch), ihres Erscheinungsjahres (1917–1977) und ihres Anspruchs, alle Kunstformen ohne Spezialisierung und geografische Einschränkung zusammenhängend zu erfassen, definiert. Es folgen Bemerkungen zum Wesen des Überblickswerks selbst. Der Hauptteil der Analyse gliedert sich in fünf Kapitel, die den Durchsetzungsprozess in ihrer Summe nachvollziehen lassen: Kapitel 1 behandelt die kunsthistorischen Legitimationen der Abstraktion, fragt also nach ihrer Einordnung und Herleitung in die linear entworfene Kunsthistoriographie. Das zweite Kapitel konzentriert sich auf den Kanon der abstrakten Maler*innen innerhalb der Standardwerke: Wer wurde als Protagonist*in der Abstraktion anerkannt? Das folgende dritte Kapitel befasst sich mit Urteilsdirektiven und Ausblicken, die die Abstraktion im Überblickswerk hervorrief: Verkörperte sie die Kunst der Zukunft oder das Übel der Entästhetisierung? Es folgt eine Analyse der Begriffe, die im kunsthistorischen Standardwerk zur Beschreibung abstrakter Bilder verwendet werden. Die Analyse endet in Kapitel 5 mit einem Vergleich der Illustrationen nach gegenstandsloser Kunst, ihrem strategischen Potenzial und ihrer Herkunft. Die Autonomisierung der Abstrakten Kunst konnte so anhand verschiedener Diskurssegmente innerhalb kunsthistorischer Standardwerke um 1977 nachgewiesen werden: Die zunehmende Ausdifferenzierung ihrer Legitimation, die Internationalisierung ihrer Künstler*innenkanons, die Homogenisierung und Objektivierung ihres Vokabulars, die Abwesenheit eines persönlichen Autorenurteils und die gleichberechtigte Sichtbarmachung ihrer Abstraktionsweisen im letzten Viertel des 20. Jahrhunderts belegen die definitive Stabilität der Abstrakten Kunst.

description: Based on a recent purely geometric construction of observables for the spatial diffeomorphism constraint, we propose two distinct quantum reductions to spherical symmetry within full 3+1-dimensional loop quantum gravity. The construction of observables corresponds to using the radial gauge for the spatial metric and allows to identify rotations around a central observer as unitary transformations in the quantum theory. Group averaging over these rotations yields our first proposal for spherical symmetry. Hamiltonians of the full theory with angle-independent lapse preserve this spherically symmetric subsector of the full Hilbert space. A second proposal consists in implementing the vanishing of a certain vector field in spherical symmetry as a constraint on the full Hilbert space, leading to a close analogue of diffeomorphisms invariant states. While this second set of spherically symmetric states does not allow for using the full Hamiltonian, it is naturally suited to implement the spherically symmetric midisuperspace Hamiltonian, as an operator in the full theory, on it. Due to the canonical structure of the reduced variables, the holonomy-flux algebra behaves effectively as a one parameter family of 2+1-dimensional algebras along the radial coordinate, leading to a diagonal non-vanishing volume operator on 3-valent vertices. The quantum dynamics thus becomes tractable, including scenarios like spherically symmetric dust collapse.

title: Der kunsttherapeutische Prozess als Translationsprozess am Beispiel des bildnerischen Ausdrucks von Trauma
Creators: name: Kaiser, Hannah
Year: 2022

description: Traumatische Erfahrungen können unser alltägliches Leben stark beeinflussen und unser Verständnis von und unseren Bezug zu der Umwelt stören. Um eine Änderung dieser gestörten Relation zur Umwelt zu bewirken, ist es notwendig, dass wir uns mit unserem Trauma auseinandersetzen und ihm Ausdruck verleihen. Besonders gut eignet sich hierbei die Kunsttherapie, in der wir unsere Erfahrungen im Bild ausdrücken, sie aus einer neuen Perspektive betrachten und schließlich verarbeiten können. In diesem Prozess findet sich auch die Translation wieder. Basierend auf Cookes Konzept der Translation als Änderung der relationalen Dynamik wird in dieser Arbeit davon ausgegangen, dass die Kunsttherapie ein relationaler Translationsprozess ist, welcher die Dynamik des Ereignisses und unseres subjektiven Erlebnisses zwangsläufig umgestaltet. Mit anderen Worten kommt es durch den kunsttherapeutischen (Translations-)Prozess zu einer Änderung des Bezuges zum Trauma und somit auch zu einer Änderung der gestörten Relation zur Umwelt. So gesehen kann argumentiert werden, dass der kunsttherapeutische Prozess ein Translationsprozess ist und die Unabdingbarkeit der Translation für die Arbeit mit Trauma gegeben ist.
description: Traumatic experiences can have a strong impact on our everyday life, and disturb our under-standing of, and relationship with our environment. In order to change this disturbed rela-tion to the environment, it is necessary to deal with and express this trauma. Art therapy is particularly suitable for this, as it allows us to express our experiences visually, view them from a new perspective, and eventually process them. Translation is also found in this pro-cess. Based on Cooke's concept of translation as a change in relational dynamics, we can conclude that art therapy is in fact a translational relational process as it inevitably trans-forms the dynamics of our subjective experience of the traumatic event. In other words, through the art-therapeutic (translational) process our relationship with trauma changes, and thus there is also a change in our disturbed relationship with the environment. We would then argue that this translational process within art therapy is crucial for trauma work.

description: We consider nonparametric estimation for functional autoregressive processes with Markov switching. First, we study the case where complete data is available; i.e. when we observe the Markov switching regime. Then we estimate the regression function in each regime using a Nadaraya-Watson type estimator. Second, we introduce a nonparametric recursive algorithm in the case of hidden Markov switching regime. Our algorithm restores the missing data by means of a Monte-Carlo step and estimate the regression function via a Robbins-Monro step. Consistency of the estimators are proved in both cases. Finally, we present some numerical experiments on simulated data illustrating the performances of our nonparametric estimation procedure.

description: Additional file 16: Gene expression profile of Tpm1. pdf. Analysis and visualization of the microarray data obtained for Tpm1. The upper 3 plots show the log2 transformed expression values of Tpm1 over the course of its probes and probesets per exon. While the red lines show the intensity values of the control samples (vehicle and untreated), the 3 shades of green represent the expression intensities in the samples at the three different time points after seizures. The upper plot shows raw probe level intensities and grey bins stand for the individual probes. The middle plot shows the normalized intensities summarized to probeset level (probes divided by grey bins) for every sample. The lower plot shows the log2 ratio calculated from the mean of the intensities seen in the second plot, each line represents one of the 3 time points after seizure. At the bottom 3 types of exon models are depicted. The dark blue boxes represent the probesets per exons, which were included in the microarray analysis. The yellow boxes and track correspond to genomic sequence and each box indicates an exon. The light blue tracks and boxes represent the only so far annotated transcript present in the Ensembl database.

description: Die Beantwortung der Frage, ob aufgrund der COVID-19-Pandemie ein Bestandzinsminderungsanspruch oder ein gänzlicher Entfall für Gewerbetreibende besteht, kann auch nach über zwei Jahren Leben mit der Pandemie nicht pauschal erfolgen. Selbst eine branchenspezifische Antwort kann nicht so einfach gegeben werden, da vielfach auf den Umstand des Einzelfalls abzustellen ist. Einige Unklarheiten konnten jedoch durch die bereits ergangenen OGH-Entscheidungen eindeutig geklärt werden und bilden sohin eine gute Ausgangsbasis bei der Ermittlung der jeweiligen Rechtslage.

description: We study occupation time statistics in ergodic continuous-time random walks. Under thermal detailed balance conditions, the average occupation time is given by the Boltzmann-Gibbs canonical law. But close to the non-ergodic phase, the finite-time fluctuations around this mean are large and nontrivial. They exhibit dual time scaling and distribution laws: the infinite density of large fluctuations complements the Lévy-stable density of bulk fluctuations. Neither of the two should be interpreted as a stand-alone limiting law, as each has its own deficiency: the infinite density has an infinite norm (despite particle conservation), while the stable distribution has an infinite variance (although occupation times are bounded). These unphysical divergences are remedied by consistent use and interpretation of both formulas. Interestingly, while the system's canonical equilibrium laws naturally determine the mean occupation time of the ergodic motion, they also control the infinite and Lévy-stable densities of fluctuations. The duality of stable and infinite densities is in fact ubiquitous for these dynamics, as it concerns the time averages of general physical observables.

description: Wilson’s Disease (WD) is a well-known genetic disorder commonly occurring in mammals. It results from a mutation in ATP7B, a copper pump found in the trans-Golgi network in certain ells. ATP7B is responsible for supplying ceruloplasmin with copper and/or exporting copper into the biliary canuli, the primary method of copper excretion. WD patients are unable to excrete copper into the bile, resulting in liver copper accumulation. Earlier studies found a <2 kDa small copper carrier (SCC) in the blood and urine of WD mice, which may excrete excess copper to maintain homeostasis. Our goal was to determine whether SCC is secreted by liver (RHC) intestinal (Caco2), and kidney epithelial cells (NRK) and the effects of excess copper on SCC secretion. Caco2 and NRK cells were grown as monolayers with tight junctions on filters in bicameral chambers to determine whether SCC or other small copper components were secreted and if so, the direction of the secretion, apically into the gut lumen and proximal tubules, respectively, and basolaterally into the bloodstream. RHC cells were grown in regular flasks. Most cells were incubated in 5 µM Cu:His2 at least 8 h and allowed to secrete copper into fresh copper-free minimum essential medium for up to 24 h. Secretions were ultrafiltered (3-kDa cutoff), concentration by lyophilization, and passed through Superdex 30/100 Increase size-exclusion chromatography. All cell types secreted small copper binding components. RHC cell secreted 650 and 440 Da components, copper pretreatment enhanced secretion. The Caco2 and NRK cell monolayers, primarily secreted them apically. However, addition of albumin to the basolateral (blood side) of the Caco2 monolayers reversed the direction of secretion. Caco2 cells secreted components (2260 and 330 Da apically and 440 Da basolaterally), NRK cells 4 distinct components (1200, 500, 330, and <100 Da). The secreted copper components were not GHK-Cu or Cu:His2. The nature and identity of these components remains to be determined.

description: Recent theoretical studies employing density-functional theory have predicted BaBiO$_{3}$ (when doped with electrons) and YBiO$_{3}$ to become a topological insulator (TI) with a large topological gap (~ 0.7 eV). This, together with the natural stability against surface oxidation, makes the Bismuth-Oxide family of special interest for possible applications in quantum information and spintronics. The central question, we study here, is whether the hole-doped Bismuth Oxides, i.e. Ba$_{1-x}$K$_{x}$BiO$_{3}$ and BaPb$_{1-x}$Bi$_{x}$O$_{3}$, which are "high-Tc" bulk superconducting near 30 K, additionally display in the further vicinity of their Fermi energy $E_{F}$ a topological gap with a Dirac-type of topological surface state. Our electronic structure calculations predict the K-doped family to emerge as a TI, with a topological gap above $E_{F}$. Thus, these compounds can become superconductors with hole-doping and potential TIs with additional electron doping. Furthermore, we predict the Bismuth-Oxide family to contain an additional Dirac cone below $E_{F}$ for further hole doping, which manifests these systems to be candidates for both electron- and hole-doped topological insulators.
