description: Using the iterative solution of Boltzmann equation in the relaxation-time approximation, the derivation of a third-order evolution equation for shear stress tensor is presented. To this end we first derive the expression for viscous corrections to the phase-space distribution function, $f(x,p)$, up to second-order in derivative expansion. The expression for $δf(x,p)$ obtained in this method does not lead to violation of the experimentally observed $1/\sqrt{m_T}$ scaling of the femtoscopic radii, as opposed to the widely used Grad's 14-moment approximation. Subsequently, we present the derivation of a third-order viscous evolution equation and demonstrate the significance of this derivation within one-dimensional scaling expansion. We show that results obtained using third-order evolution equations are in excellent accordance with the exact solution of Boltzmann equation as well as with transport results.

Creators: name: Kaya, Selma Anna Maria

description: Seit einigen Jahren ist die sogenannte „Brennpunktschule“ in aller Munde. Sie stellt einen vermeintlichen Ausnahme- oder sogar Extremfall der schulischen Segregation in Österreich dar und wird nicht selten als Ort der Gefahr und des sozialen Niedergangs gezeichnet. Ob-wohl eine Reihe von Uneinigkeiten über die „Brennpunktschule“ besteht, sollen Kinder und Jugendliche mit „Migrationshintergrund“ allen voran diejenigen islamischen Glaubens dafür verantwortlich sein, dass „Brennpunktschulen“ entstehen. Das liegt daran, dass im Nachden-ken über die Entstehung bestimmter Räume ein veraltetes Raumverständnis zu tragen kommt, das soziale Mechanismen nicht mitberücksichtigt. Die vorliegende Masterarbeit widmet sich der bestehenden Forschungslücke, die es hinsichtlich der Bedeutung sprachlicher Benennun-gen von Räumen für ihre Entstehung gibt. Die Analyse politischer Kommunikation zeigt nicht nur, wie Bildungsräume gedacht werden, sondern auch welche gesellschaftliche Funktion der Adressierung bestimmter Schulen entlang von Defizitsemantiken, wie der „Brennpunktschule“ zukommt.

Publisher: name: Old Dominion University Libraries

description: The following essay investigates Tintoretto’s, a Venetian artist during the 16th century, artist techniques in his painting the Last Supper and how the period is reflected within it. For instance, the chiaroscuro and sfumato techniques in the painting are used to allude the darkness surrounding the self-indulgence, financial abuses, and religious corruption during the Counter-Reformation. Research of underlying symbolism and historical events further reveal how the Last Supper reflects the dark, confusing time that Europe was in during the Counter-Reformation. Understanding the Last Supper and understanding it’s historical context aids in the ability to observe the emotions during that period and how religion can change the course of how art is created and the way in which biblical scenes are depicted within art.

description: In the framework of an interference setup in which only two outcomes are possible (such as in the case of a Mach-Zehnder interferometer), we discuss in a simple and pedagogical way the difference between a standard, unitary quantum mechanical evolution and the existence of a real collapse of the wave function. Moreover, we also present the Elitzur-Vaidman bomb, the delayed choice experiment, and the effect of decoherence. In the end, we propose two simple experiments to visualize decoherence and to test the role of an entagled particle.

description: A sequence of Markov chains is said to exhibit (total variation) cutoff if the convergence to stationarity in total variation distance is abrupt. We consider reversible lazy chains. We prove a necessary and sufficient condition for the occurrence of the cutoff phenomena in terms of concentration of hitting time of "worst" (in some sense) sets of stationary measure at least $α$, for some $α\in (0,1)$. We also give general bounds on the total variation distance of a reversible chain at time $t$ in terms of the probability that some "worst" set of stationary measure at least $α$ was not hit by time $t$. As an application of our techniques we show that a sequence of lazy Markov chains on finite trees exhibits a cutoff iff the ratio of their relaxation-times and their (lazy) mixing-times tends to 0.

description: The calibration of a measurement device is crucial for every scientific experiment, where a signal has to be inferred from data. We present CURE, the calibration uncertainty renormalized estimator, to reconstruct a signal and simultaneously the instrument's calibration from the same data without knowing the exact calibration, but its covariance structure. The idea of CURE, developed in the framework of information field theory, is starting with an assumed calibration to successively include more and more portions of calibration uncertainty into the signal inference equations and to absorb the resulting corrections into renormalized signal (and calibration) solutions. Thereby, the signal inference and calibration problem turns into solving a single system of ordinary differential equations and can be identified with common resummation techniques used in field theories. We verify CURE by applying it to a simplistic toy example and compare it against existent self-calibration schemes, Wiener filter solutions, and Markov Chain Monte Carlo sampling. We conclude that the method is able to keep up in accuracy with the best self-calibration methods and serves as a non-iterative alternative to it.

description: Edge states are one important ingredient to understand transport properties of graphene nanoribbons. We study experimentally the existence and the internal structure of edge states under uniaxial strain of the three main edges: zigzag, bearded, and armchair. The experiments are performed on artificial microwave graphene flakes, where the wavefunctions are obtained by direct imaging. We show that uniaxial strain can be used to manipulate the edge states: a single parameter controls their existence and their spatial extension into the ribbon. By combining tight-binding approach and topological arguments, we provide an accurate description of our experimental findings. A new type of zero-energy state appearing at the intersection of two edges, namely the corner state, is also observed and discussed.

Species Conservation Management Plan Report and Class Exercise
Creators: name: Rodgers, Vikki
Publisher: name: QUBES Educational Resources
Year: 2023

description: In this project, students work in pairs to become an expert in their assigned IUCN Red List endangered species. They are charged to create a well-researched, written conservation management plan. They must include all ecologically-relevant information for their species (including the socio-ecological system in which they reside), indicate current threats & propose a conservation plan. Students are asked to recognize which communities of humans are impacted by the decline of this species and make a case for whether this species should be saved and how feasible it would be. A class exercise is designed for the sharing of information to learn about other species and see trends through a “speed dating” activity.

description: We extend the stochastic Perron method to analyze the framework of stochastic target games, in which one player tries to find a strategy such that the state process almost surely reaches a given target no matter which action is chosen by the other player. Within this framework, our method produces a viscosity sub-solution (super-solution) of a Hamilton-Jacobi-Bellman (HJB) equation. We then characterize the value function as a viscosity solution to the HJB equation using a comparison result and a byproduct to obtain the dynamic programming principle.

description: We investigate possible realizations of exotic SU(N) symmetry-protected topological (SPT) phases with alkaline-earth cold fermionic atoms loaded into one-dimensional optical lattices. A thorough study of two-orbital generalizations of the standard SU(N) Fermi-Hubbard model, directly relevant to recent experiments, is performed. Using state-of-the-art analytical and numerical techniques, we map out the zero-temperature phase diagrams at half-filling and identify several Mott-insulating phases. While some of them are rather conventional (non-degenerate, charge-density-wave or spin-Peierls like), we also identify, for even-N, two distinct types of SPT phases: an orbital-Haldane phase, analogous to a spin-N/2 Haldane phase, and a topological SU(N) phase, which we fully characterize by its entanglement properties. We also propose sets of non-local order parameters that characterize the SU(N) topological phases found here.

description: Stellen Sie sich vor, Sie können nicht mitteilen, was Sie bewegt, was Sie sich wünschen oder was Sie essen möchten. Kommunikation ist ein Grundbedürfnis des Menschen. Was aber, wenn diese durch eine körperliche oder geistige Beeinträchtigung erschwert wird, was wenn Menschen sich nicht verständlich machen können? In dieser Arbeit geht es darum, herauszustellen, welche Möglichkeiten es für die Soziale Arbeit gibt, eine gelingende Kommunikation in der Zusammenarbeit mit erwachsenen Menschen mit einer schweren mehrfachen Beeinträchtigung im stationären Setting mit adäquater Nähe zu gestalten und damit Partizipation und Selbstbestimmung fördern zu können. Für diese Literaturarbeit wurden die Erkenntnisse aus verschiedenen literarischen Quellen gewonnen und strukturiert verwendet. Der Schwerpunkt dieser Arbeit liegt neben den verschiedene Vorrausetzungen, wie dem des personenzentrierten Ansatzes und der professionellen Nähe hauptsächlich auf der Anwendung der Basalen Stimulation, um eine gelingende Kommunikation gestalten zu können. Eine praxisnahe Betrachtung der Möglichkeiten zur Kommunikation mit Menschen mit einer schweren mehrfachen Beeinträchtigung soll verdeutlichen, wie die Umsetzung dieser Kommunikation im stationären Setting gelingen kann. Als eine der wichtigsten Erkenntnisse für die Praxis gilt die Schulung und Weiterbildung von Fachpersonen in ihren kommunikativen Kompetenzen. Die Ergebnisse dieser Arbeit verweisen darauf, dass es für eine gelingende Kommunikation vieler Ressourcen seitens der Professionellen der Sozialen Arbeit bedarf, um dadurch Partizipation und Selbstbestimmung für Menschen mit einer Beeinträchtigung fördern zu können.

description: Body odour disgust sensitivity (BODS) reflects a behavioural disposition to avoid pathogens, and it may also involve social attitudes. Among participants in the USA, high levels of BODS were associated with stronger xenophobia towards a fictitious refugee group. To test the generalizability of this finding, we analysed data from nine countries across five continents (N = 6836). Using structural equation modelling, we found support for our pre-registered hypotheses: higher BODS levels were associated with more xenophobic attitudes; this relationship was partially explained by perceived dissimilarities of the refugees' norms regarding hygiene and food preparation, and general attitudes toward immigration. Our results support a theoretical notion of how pathogen avoidance is associated with social attitudes: ‘traditional norms’ often involve behaviours that limit inter-group contact, social mobility and situations that might lead to pathogen exposure. Our results also indicate that the positive relationship between BODS and xenophobia is robust across cultures.

description: As the energy relaxation time of superconducting qubits steadily improves, non-equilibrium quasiparticle excitations above the superconducting gap emerge as an increasingly relevant limit for qubit coherence. We measure fluctuations in the number of quasiparticle excitations by continuously monitoring the spontaneous quantum jumps between the states of a fluxonium qubit, in conditions where relaxation is dominated by quasiparticle loss. Resolution on the scale of a single quasiparticle is obtained by performing quantum non-demolition projective measurements within a time interval much shorter than $T_1$, using a quantum limited amplifier (Josephson Parametric Converter). The quantum jumps statistics switches between the expected Poisson distribution and a non-Poissonian one, indicating large relative fluctuations in the quasiparticle population, on time scales varying from seconds to hours. This dynamics can be modified controllably by injecting quasiparticles or by seeding quasiparticle-trapping vortices by cooling down in magnetic field.

description: We derive the statistics of the efficiency under the assumption that thermodynamic fluxes fluctuate with normal law, parametrizing it in terms of time, macroscopic efficiency, and a coupling parameter $ζ$. It has a peculiar behavior: No moments, one sub- and one super-Carnot maxima corresponding to reverse operating regimes (engine/pump), the most probable efficiency decreasing in time. The limit $ζ\to 0$ where the Carnot bound can be saturated gives rise to two extreme situations, one where the machine works at its macroscopic efficiency, with Carnot limit corresponding to no entropy production, and one where for a transient time scaling like $1/ζ$ microscopic fluctuations are enhanced in such a way that the most probable efficiency approaches Carnot at finite entropy production.

title: Zweisprachigkeit und Zugehörigkeit der zweiten rumänischen Migrationsgeneration in Österreich
Creators: name: Vlas, Ruth

description: Die vorliegende Arbeit wirft einen Blick auf das Zugehörigkeitsgefühl der zweiten rumänischen Migrationsgeneration in Österreich. Das Ziel dieser Arbeit ist es dementsprechend einen Zusammenhang zwischen der Zweisprachigkeit und der Zugehörigkeit der zweiten Generation zu erfragen. Hierbei wird folgende Forschungsfrage gestellt: Inwiefern wird Zugehörigkeit durch Zweisprachigkeit von der zweiten rumänischen Migrationsgeneration in Österreich erfahren? Um dieses Ziel zu erreichen und die Forschungsfrage beantworten zu können, ist eine qualitative Studie durchgeführt worden, die auf eine weitreichende Literaturrecherche basiert. Aus der qualitativen Inhaltsanalyse ging heraus, dass die zweite Generation die Zweisprachigkeit auf unterschiedliche Weise und in verschiedenen Kontexten benutzt. Durch ihre Zweisprachigkeit können sich Kommunikationsbarrieren entwickeln, die oftmals auch in Stereotypisierungen ihren Ursprung haben und die eigene emotionale Zuordnung beeinflussen. Positive und negative Erlebnisse schaffen ein eigenes Weltbild. Dies äußert sich unter anderem in den gemeinsamen Kommunikations- und Interaktionsmustern, die sich vor allem durch das Code-Switching äußern. Von den interviewten Personen ging heraus, dass diese oftmals ein Leben zwischen zwei Welten wahrnehmen, in welchen sie weder zur einen noch zur anderen gehören, sich jedoch beiden verbunden fühlen. Anhand der Diskussion um Muttersprache wird ersichtlich, wie Personen der zweiten rumänischen Migrationsgeneration Grenzziehungen der Zugehörigkeit empfinden.
description: The present work looks at the sense of belonging of the second generation of Romanian migrants in Austria. The aim of this paper is therefore to investigate the relationship between bilingualism and the belonging of the second-generation. Consequently, the research question is: To what extent is belonging experienced by the second generation of Romanian migrants in Austria through bilingualism? To achieve this objective and to answer the research question, a qualitative study was carried out based on an extensive literature research. The qualitative content analysis shows that the second generation uses bilingualism in different ways and in different contexts. Their bilingualism can lead to the development of communication barriers, which often have their roots in stereotyping. Based on the positive and negative experiences, an emotional affiliation helps in the creation of their own worldview. This is reflected in the common patterns of communication and interaction, which are mainly reflected in Code Switching. The interviewees found that they often experience a life between two worlds, in which they do not belong to one or the other but feel connected to both. The discussion about mother tongue reveals how people of the second generation feel along the boundary lines of belonging.

description: The study of scattering processes in few body systems is a difficult problem especially if long range interactions are involved. In order to solve such problems, we develop here a potential-splitting approach for three body systems. This approach is based on splitting the reaction potential into a finite range core part and a long range tail part. The solution to the Schrödinger equation for the long range tail Hamiltonian is found analytically, and used as an incoming wave in the three body scattering problem. This reformulation of the scattering problem makes it suitable for treatment by the exterior complex scaling technique in the sense that the problem after the complex dilation is reduced to a boundary value problem with zero boundary conditions. We illustrate the method with calculations on the electron scattering off the hydrogen atom and the positive helium ion in the frame of the Temkin-Poet model.

description: Many large-scale applications require electromagnetic modelling with extensive numerical computations, such as magnets or 3-dimensional (3D) objects like transposed conductors or motors and generators. Therefore, it is necessary to develop computationally time-efficient but still accurate numerical methods. This article develops a general variational formalism for any ${\bf E}({\bf J})$ relation and applies it to model coated-conductor coils containing up to thousands of turns, taking magnetization currents fully into account. The variational principle, valid for any 3D situation, restricts the computations to the sample volume, reducing the computation time. However, no additional magnetic materials interacting with the superconductor are taken directly into account. Regarding the coil modelling, we use a power law $E(J)$ relation with magnetic field-dependent critical current density, $J_c$, and power law exponent, $n$. We test the numerical model by comparing the results to analytical formulas for thin strips and experiments for stacks of pancake coils, finding a very good agreement. Afterwards, we model a magnet-size coil of 4000 turns (stack of 20 pancake coils of 200 turns each). We found that the AC loss is mainly due to magnetization currents. We also found that for an $n$ exponent of 20, the magnetization currents are greatly suppressed after 1 hour relaxation. In addition, in coated conductor coils magnetization currents have an important impact on the generated magnetic field; which should be taken into account for magnet design. In conclusion, the presented numerical method fulfills the requirements for electromagnetic design of coated conductor windings.

description: The PI3K/AKT/mTOR pathway is a significant target for cancer drug discovery. Many efforts have focused on discovering new inhibitors against key kinase proteins involved in this pathway for cancer treatment. PI3K/mTOR dual inhibitors, such as PKI-179, have been reported to be more effective than agents that act only on a single protein target. The present computational study aimed to discover triple target inhibitors against PI3K, AKT, and mTOR proteins. Accordingly, the PI3K protein bound with the ligand was used as input for e-pharmacophore modelling to generate the pharmacophore hypothesis and then screened for a library of 270,540 natural products from the Zinc database resulting in 57,220 compounds that matched the hypothesis. These compounds were then docked into the active site of PI3K, resulting in 292 compounds with better docking scores than the co-crystallized ligand. These compounds were re-docked into AKT and mTOR proteins. Besides, MM-GBSA binding free energy calculations, MD simulations, and ADMET prediction were carried out, leading to 5 potential triple-target inhibitors namely, ZINC000014644152, ZINC000014760695, ZINC000014644839, ZINC000095099451, and ZINC000005998557. In conclusion, these inhibitors may be possible leads for inhibiting PI3K/AKT/mTOR pathway, and they may be further evaluated in vitro and clinically as anticancer agents.

description: Coronal mass ejections (CMEs) are thought to drive collisionless shocks in the solar corona, which in turn have been shown capable of accelerating solar energetic particles (SEPs) in minutes. It has been notoriously difficult to extract information about energetic particle spectra in the corona, due to lack of in-situ measurements. It is possible, however, to combine remote observations with data-driven models in order to deduce coronal shock properties relevant to the local acceleration of SEPs and their heliospheric connectivity to near-Earth space. We present such novel analysis applied to the May 11, 2011 CME event on the western solar limb, focusing on the evolution of the eruption-driven, dome-like shock wave observed by the Atmospheric Imaging Assembly (AIA) EUV telescopes on board the Solar Dynamics Observatory spacecraft. We analyze the shock evolution and estimate its strength using emission measure modeling. We apply a new method combining a geometric model of the shock front with a potential field source surface model to estimate time-dependent field-to-shock angles and heliospheric connectivity during shock passage in the low corona. We find that the shock was weak, with an initial speed of ~450 km/s. It was initially mostly quasi-parallel, but significant portion of it turned quasi-perpendicular later in the event. There was good magnetic connectivity to near-Earth space towards the end of the event as observed by the AIA instrument. The methods used in this analysis hold a significant potential for early characterization of coronal shock waves and forecasting of SEP spectra based on remote observations.

description: For a stochastic differential equation(SDE) driven by a fractional Brownian motion(fBm) with Hurst parameter $H>\frac{1}{2}$, it is known that the existing (naive) Euler scheme has the rate of convergence $n^{1-2H}$. Since the limit $H\rightarrow\frac{1}{2}$ of the SDE corresponds to a Stratonovich SDE driven by standard Brownian motion, and the naive Euler scheme is the extension of the classical Euler scheme for Itô SDEs for $H=\frac{1}{2}$, the convergence rate of the naive Euler scheme deteriorates for $H\rightarrow\frac{1}{2}$. In this paper we introduce a new (modified Euler) approximation scheme which is closer to the classical Euler scheme for Stratonovich SDEs for $H=\frac{1}{2}$, and it has the rate of convergence $γ_n^{-1}$, where $γ_n=n^{2H-{1}/2}$ when $H\frac{3}{4}$. Furthermore, we study the asymptotic behavior of the fluctuations of the error. More precisely, if $\{X_t,0\le t\le T\}$ is the solution of a SDE driven by a fBm and if $\{X_t^n,0\le t\le T\}$ is its approximation obtained by the new modified Euler scheme, then we prove that $γ_n(X^n-X)$ converges stably to the solution of a linear SDE driven by a matrix-valued Brownian motion, when $H\in(\frac{1}{2},\frac{3}{4}]$. In the case $H>\frac{3}{4}$, we show the $L^p$ convergence of $n(X^n_t-X_t)$, and the limiting process is identified as the solution of a linear SDE driven by a matrix-valued Rosenblatt process. The rate of weak convergence is also deduced for this scheme. We also apply our approach to the naive Euler scheme.

description: The circulatory system, composed of an intricate hierarchical network of branching blood vessels, delivers dissolved nutrients and gases to more than 37 trillion cells in the human body. Pathologies that impair these blood vessels, i.e., cardiovascular disease, afflict nearly a million Americans and more than 17 million patients worldwide. To combat the incidence and subsequent progression of cardiovascular disease, researchers have sought to develop in vitro models of vasculature and transplant engineered, vascularized tissue. These efforts have encountered three primary obstacles that have hindered the translation of vascular tissue engineering to the clinic. First, current cell sources are inadequate: cells isolated from other adult patients rapidly undergo senescence and engender an immune response upon implantation. Second, there is a dearth of biomaterials that recapitulate the dynamic signaling environment of the extracellular matrix, which is critical to ensuring a physiological response in vivo. Third, current quantification methods are insufficient: comparing vascular network topologies across different studies remains a difficult endeavor, and many algorithms unnecessarily simplify a complex three-dimensional structure to a planar analysis. To specifically address these three challenges, we quantitatively evaluated the vasculogenic potential, i.e., ability to self-assemble into vessel-like networks, of induced pluripotent stem cell-derived endothelial progenitors (iPSC-EPs) in extracellular matrix-mimicking biomaterials. In this dissertation, we describe the derivation, isolation, and encapsulation of iPSC-EPs in collagen hydrogels. We varied the structural protein density, the concentration of angiogenic growth factor, and proteolytic activity to optimize the resulting microvascular network. We additionally developed a novel computational pipeline, constructed in ImageJ and MATLAB, to quantitatively evaluate vascular network topology while preserving the architecture of the network. However, the collagen hydrogels compacted rapidly and exhibited limited mechanical strength. We, therefore, synthesized a novel hybrid interpenetrating polymer network (IPN) hydrogel composed of collagen and norbornene-modified hyaluronic acid (NorHA). Our results suggested that this IPN hydrogel exhibited highly tunable mechanical properties, resisted compaction, and stimulated angiogenesis. Our two studies underscore the importance of understanding the role of mechano-regulation on vasculogenesis so that ECM-mimicking angiogenic biomaterials can be effectively deployed in the clinic and ultimately improve vascular health

description: Palliative care focusing on pain and infection is recommended for patients who are terminally ill. It is difficult to implement this strategy in practice because of the lack of clear guidelines. The authors conducted a study to examine dental treatment provided to a group of long-term care (LTC) residents in the last year of life.
Capacités cognitives et détection des jeunes talents sportifs Cognitive abilities and detection of young sports talents

description: Physical and sports practice, in general, requires the analysis of a large amount of information intended tochoose and produce a fast and effective motor response. For this purpose, cognitive functions (attention, memory, etc.) are involved in the processing of analysis, command and control and movement planning operations. These processes intervene in a hierarchical manner and largely condition sports performance and to be effective, athletes must possess, in addition to physical and motor abilities, above-average perceptual-cognitive abilities. It's a descriptive work which aims is to address the contribution of the evaluation and training of cognitive functions through the use of two psychomotor tests: Attention (STROOP, 1999) andMemory (FCR, Wallon and Mesmin, 2009) for the detection and selection of young sports talents

description: The human microbiome and its crosstalk with host cells play a critical role in regulating human health and disease. However, the underlying mechanism of how the host-microbiome crosstalk affects the disease etiology remains largely elusive, mainly because of a lack of reliable model systems. It has been demonstrated that the microphysiological human gut-on-a-chip system enables to stably co-culture the living human microbiome under the physiologically relevant tissue microarchitecture and biomechanical cues to recapitulate complex crosstalk in the epithelium-microbiome-immune axis in the intestinal microenvironment. By leveraging this innovative technology, the mechanistic investigation of epithelial morphogenesis, the establishment of a novel platform to co-culture anaerobic bacteria, the identification of the etiological trigger in the intestinal inflammation, and the development of patient-specific intestinal disease models by integrating patient’s samples have been performed. The development and utilization of the microphysiological human intestine models can potentially produce disseminating impacts to deciphering the host-microbiome crosstalk in gastrointestinal diseases

description: Josephson weak links made of two-dimensional topological insulators (TIs) exhibit magnetic oscillations of the supercurrent that are reminiscent of those in superconducting quantum interference devices (SQUIDs). We propose a microscopic theory of this effect that goes beyond the approaches based on the standard SQUID theory. For long junctions we find a temperature-driven crossover from Phi_0-periodic SQUID-like oscillations to a 2 Phi_0-quasiperiodic interference pattern with different peaks at even and odd values of the magnetic flux quantum Phi_0=ch/2e. This behavior is absent in short junctions where the main interference signal occurs at zero magnetic field. Both types of interference patterns reveal gapless (protected) Andreev bound states. We show, however, that the usual sawtooth current-flux relationship is profoundly modified by a Doppler-like effect of the shielding current which has been overlooked previously. Our findings may explain recently observed even-odd interference patterns in InAs/GaSb-based TI Josephson junctions and uncover unexplored operation regimes of nano-SQUIDs.

description: Let PL+(S1) be the group of order preserving piecewise linear homeomorphisms of the circle. An element in PL+(S1) is called reversible in PL+(S1) if it is conjugate to its inverse in PL+(S1). We characterize the reversible elements in PL+(S1). We also perform a sim- ilar characterisation in the full group PL(S1) of piecewise linear home- omorphisms of the circle.

description: We investigate the electrical conductivity(EC) of dense quark matter in the vicinity of the phase transition line. We show that: (i) At high density the Drude EC does not depend on the magnetic field up to $eB \sim 10^{19} \ G$. (ii) In the precritical region the fluctuation EC (paraconductivity) dominates over the Drude one.
