description: This article gives a complete account of the modular properties and Verlinde formula for conformal field theories based on the affine Kac-Moody algebra sl(2) at an arbitrary admissible level k. Starting from spectral flow and the structure theory of relaxed highest weight modules, characters are computed and modular transformations are derived for every irreducible admissible module. The culmination is the application of a continuous version of the Verlinde formula to deduce non-negative integer structure coefficients which are identified with Grothendieck fusion coefficients. The Grothendieck fusion rules are determined explicitly. These rules reproduce the well-known fusion rules of Koh and Sorba, negative coefficients included, upon quotienting the Grothendieck fusion ring by a certain ideal.

description: The Chandra Deep Field is the region of the sky with the highest concentration of X-ray data available: 4Ms of Chandra and 3Ms of XMM data, allowing excellent quality spectra to be extracted even for faint sources. We take advantage of this in order to compile a sample of heavily obscured Active Galactic Nuclei (AGN) using X-ray spectroscopy. We select our sample among the 176 brightest XMM sources, searching for either a) flat X-ray spectra (Photon index<1.4 at the 90% confidence level) suggestive of a reflection dominated continuum or b) an absorption turn-over suggestive of a column density higher than ~10^{24} cm-2. We find a sample of nine candidate heavily obscured sources satisfying the above criteria. Four of these show statistically significant FeKalpha lines with large equivalent widths (three out of four have EW consistent with 1 keV) suggesting that these are the most secure Compton-thick AGN candidates. Two of these sources are transmission dominated while the other two are most probably reflection dominated Compton-thick AGN. Although this sample of four sources is by no means statistically complete, it represents the best example of Compton-thick sources found at moderate-to-high redshift with three sources at z=1.2-1.5 and one source at z=3.7. Using Spitzer and Herschel observations, we estimate with good accuracy the X-ray to mid-IR (12 micron) luminosity ratio of our sources. These are well below the average AGN relation, independently suggesting that these four sources are heavily obscured.

description: The amplification and maintenance of the observed magnetic fields in the ICM are usually attributed to the turbulent dynamo action. This is generally derived employing a collisional MHD model. However, in the ICM the ion mean free path between collisions is of the order of the dynamical scales, thus requiring a collisionless MHD description. Unlike collisional MHD simulations, our study uses an anisotropic plasma pressure with respect to the direction of the local magnetic field, which brings the plasma within a parameter space where collisionless instabilities should take place. Within the adopted model these instabilities are contained at bay through the relaxation term of the pressure anisotropy which simulates the feedback of the mirror and firehose instabilities. This relaxation acts to get the plasma distribution function consistent with the empirical studies of collisionless plasmas. Our 3D numerical simulations of forced transonic turbulence motivated by modeling of the turbulent ICM are performed for different initial values of the magnetic field intensity, and different relaxation rates of the pressure anisotropy. We found that in the high beta plasma regime corresponding to the ICM conditions, a fast anisotropy relaxation rate gives results which are similar to the collisional-MHD model as far as the statistical properties of the turbulence are concerned. Also, the amplification of seed magnetic fields due to the turbulent dynamo action is similar to the collisional-MHD model. Our simulations that do not employ the anisotropy relaxation deviate significantly from the collisional-MHD results, and show more power at the small-scale fluctuations of both density and velocity representing the results of the instabilities. For these simulations the large scale fluctuations in the magnetic field are mostly suppressed and the turbulent dynamo fails in amplifying seed magnetic fields.

description: The study of dye-surfactant interaction is very important in achieving an optimal dyeing process in textile industries. Conductivity measurements of the cationic surfactant cetylpyridinium chloride (CPC) in the presence of bromocresol green dye (BCG) in various solvents were performed, in order to provide insight into the interaction between BCG and CPC. Three critical micelle concentrations (cmc) were observed over the studied CPC concentration range. The observed cmc values of the BCG + CPC system were found to change significantly as a function of BCG concentration. The cmc values of the BCG + CPC system showed U-shaped variation, with increasing temperature in aqueous and propanol media, while decreasing monotonically in ethanol media. The concentration of additives (ethanol, propanol, and propylene glycol) also affected the cmc values significantly. The values of counterion binding (β) were also found to be dependent on the temperature and concentration of additives. Different thermodynamic parameters, e.g. Gibbs free energy (ΔGmo), enthalpy (ΔHmo), and entropy (ΔSmo) changes, as well as their transfer properties associated with micellization of the BCG + CPC system, were determined. The ΔHom and ΔSom values reveal the presence of hydrophobic, ion-dipole, or dipole-diploe interactions amongst employed constituents.

description: Auf den Punkt ...
Im Jahr 2012 arbeiteten 24,3% aller abhängig Beschäftigten für einen Stundenlohn unterhalb der bundeseinheitlichen Niedriglohnschwelle von 9,30 €.
Die Zahl der Niedriglohnbeschäftigten ist seit 1995 von 5,9 auf 8,4 Millionen im Jahr 2012 gestiegen, was einer Zunahme um rund 2,5 Millionen (bzw. 42,1%) entspricht. Der prozentuale Anstieg der Niedriglohnbeschäftigung war in Westdeutschland weitaus höher als in Ostdeutschland.

Der Anteil der Beschäftigten, die bei einem Mindestlohn von 8,50 € Anspruch auf eine Lohnerhöhung hätten, liegt je nach Berechnungsweise des Stundenlohns und der Grundgesamtheit zwischen 13,6% und 19,7% der abhängig Beschäftigten.

Zur Ausgestaltung und Umsetzung des gesetzlichen Mindestlohns sind noch wichtige Punkte offen. Dies betrifft z.B. die Erfassung der tatsächlichen Arbeitszeiten und die Frage, ob Zulagen und Sonderzahlungen bei der Einhaltung des Mindestlohns angerechnet werden dürfen.

Ausnahmeregelungen sollten eng begrenzt bleiben, weil sonst ein Wettbewerb zwischen Beschäftigtengruppen mit und ohne Mindestlohnanspruch entfacht wird. Zudem würden Ausnahmen die Durchsetzung und Kontrolle des Mindestlohns deutlich erschweren.
Learning to take risks : three essays on the relationship between early life resource availability and adults’ risk preferences

description: Why are some people systematically more willing to take risks than others? Risk preferences affect multiple aspects of life, from personal finances to health-related behavior. In crisis like the recent COVID-19 pandemic, the implications of risk-taking tendencies can be magnified—they can affect, for example, the extent to which people expose themselves and others to pandemic-related risks. Yet, individual differences in risk preferences remain poorly understood. The essays in this dissertation contribute to the understanding of how people develop long-lasting risk preferences by building upon and advancing a fast-growing literature focused on the role of socioeconomic factors in people’s early, formative years of life. Essay 1 reconciles diverging perspectives identified in this literature and generates concrete predictions centered on the idea that early life socioeconomic conditions imprint two factors in lifelong risk preferences: baseline preferences, which manifest in most contexts, and threat responses, which are induced by widespread threats like economic recessions and global pandemics. At baseline, wealthier upbringings predict greater willingness to take risks. Threat responses, however, lead adults with wealthier upbringings to reduce risk-taking and adults with less privileged upbringings to increase it. Essay 2 tests these two factors across five experiments conducted during COVID-19. Pandemic-based threat primes were employed to elicit baseline versus threat response risk-taking patterns and risk preferences were assessed based on participants’ susceptibility to COVID-19 scams—i.e., their willingness to take their chances with attractive yet potentially fraudulent offers, like early access to a vaccine that, at the time, was not available. Essay 3 clarifies how baseline risk preferences and threat responses play out during prolonged periods of crisis. Six studies suggest that threat responses exist, but are ephemeral; they arise when crises feel novel or suddenly worsen, but risk preferences return to baseline even while reality remains threatening. Thus, even in circumstances that, like the pandemic, warrant caution from everyone, adults brought up in more privileged socioeconomic conditions are more prone to engage in risky behaviors than their less privileged counterparts.
The cutoff-dependence of the Casimir force within an inhomogeneous medium

description: We consider the ground state energy of the electromagnetic field in a piston geometry. In the idealised case, where the piston and the walls of the chamber are taken as perfect mirrors, the Casimir pressure on the piston is finite and independent of the small scale physics of the media that compose the mirrors; the Casimir-energy of the system can be regularised and is cutoff-independent. Yet we find that, when the body of the piston is filled with an inhomogeneous dielectric medium, the Casimir energy is cutoff-dependent, and the value of the pressure is thus inextricably dependent on the detailed behaviour of the mirror and the medium at large wave-vectors. This result is inconsistent with recent proposals for regularising Casimir forces in inhomogeneous media.

Cato maior im Lateinunterricht - Aufstieg und Fall eines Vorzeigerömers
Creators: name: Bayer, Markus
Publisher: name: Pegasus-Onlinezeitschrift
Year: 2017

description: In der vorliegenden Arbeit untersucht Markus Bayer (Berlin) die Bedeutung des älteren Cato für den Lateinunterricht in deutschen Schulen. Dabei kommen zwei Aspekte in Betracht, die sich nicht immer eindeutig voneinander trennen lassen: Erstens wird geklärt, welche unterschiedlichen Interpretationen die historische Persönlichkeit des Zensors zu verschiedenen Zeitpunkten erfuhr und welchen Niederschlag diese im Lateinunterricht fanden. Zweitens wird der Stellenwert Catos als unterrichtsrelevanter Schulautor ermittelt. Als Hintergrund einer solchen Analyse wird gleichzeitig die Zielsetzung des altsprachlichen Unterrichts im Wandel der Zeiten reflektiert. Den älteren Cato als Gegenstand einer solchen Untersuchung auszuwählen, gibt es gute Gründe: Erstens hat Cato sich in sehr unterschiedlichen Bereichen des römischen Gesellschaftslebens einen Namen gemacht, weshalb seine Person auch vielfache Anknüpfungsmöglichkeiten im Unterricht bietet. Zweitens ist seine Persönlichkeit schon in der Antike recht widersprüchlich bewertet worden, sie trug den Kristallisationspunkt der unterschiedlichen Auslegungen gleichsam bereits zu Lebzeiten in sich. Drittens zählt er nicht zu dem engen Kreis der „Klassiker“, deren schulische Bedeutung zwar ebenfalls gewissen Schwankungen unterliegt, die aber gleichzeitig einen so festen Sitz in der Tradition des Lateinunterrichts haben, dass ihre Relevanz für den altsprachlichen Unterricht kaum je in Frage gestellt wurde. Der Fall Catos ist also gerade durch seine curriculare Randständigkeit interessant.

description: Quintilian für Lehrer? Was könnte ein römisches Handbuch der Rhetorik, die Institutio oratoria aus den Jahren 93-95 n. Chr., für die Schule heute noch bedeuten? Der Beitrag versucht, eine Antwort auf diese Frage zu geben. Ausgehend vom Ideal des orator perfectus, von dem die gesamte Institutio bestimmt ist, stellt Wolfram Ax (Köln) anhand ausgewählter Texte Quintilians Pädagogik in ihren Grundzügen dar. Sie erweist sich als eine Pädagogik von zeitlos wertvoller Humanität, die insofern besonders überrascht, als sie unter dem literatur- und bildungsfeindlichen diktatorischen Regime des Domitian propagiert wurde.

Entropy-Product Rules for Charged Rotating Black Holes

Year: 2013
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study the universal nature of the product of the entropies of all horizons of charged rotating black holes. We argue, by examining further explicit examples, that when the maximum number of rotations and/or charges are turned on, the entropy product is expressed in terms of angular momentum and/or charges only, which are quantized. (In the case of gauged supergravities, the entropy product depends on the gauge-coupling constant also.) In two-derivative gravities, the notion of the "maximum number" of charges can be defined as being sufficiently many non-zero charges that the Reissner-Nordstrom black hole arises under an appropriate specialisation of the charges. (The definition can be relaxed somewhat in charged AdS black holes in $D\ge 6$.) In higher-derivative gravity, we use the charged rotating black hole in Weyl-Maxwell gravity as an example for which the entropy product is still quantized, but it is expressed in terms of the angular momentum only, with no dependence on the charge. This suggests that the notion of maximum charges in higher-derivative gravities requires further understanding.

description: Neutrino masses and mixings can be generated in many different ways, with some of these scenarios featuring new physics at energy scales relevant for Large Hadron Collider searches. A systematic approach to constructing a large class of models for Majorana neutrinos may be founded upon a list of gauge-invariant effective operators -- formed from quarks, leptons and the Higgs doublet -- that violate lepton-number conservation by two units. By opening up these operators in all possible ways consistent with some minimality assumptions, a complete catalogue of a class of minimal radiative neutrino mass models may be produced. In this paper we present an analysis of Feynman diagram topologies relevant for the ultra-violet completions of these effective operators and collect these into a simple recipe that can be used to generate radiative neutrino mass models. Since high mass-dimension effective operators are suppressed by powers of the scale of new physics, many of the resulting models can be meaningfully tested at the Large Hadron Collider.

description: In cases where the same real-world system can be modeled both by an ODE system $\bD$ and a Boolean system $\bB$ it is of interest to identify conditions under which the two systems will be consistent, that is, will make qualitatively equivalent predictions. In this note we introduce two broad classes of relatively simple models that provide a convenient framework for studying such questions. In contrast to the widely known class of Glass networks, the right-hand sides of our ODEs are Lipschitz-continuous. We prove that under suitable assumptions about $\bB$ consistency between $\bD$ and $\bB$ will be implied by sufficient separation of time scales in one class of our models while it may fail in the other class. These results appear to point to more general structure properties that favor consistency between ODE and Boolean models.

description: We explore the conditions under which the particle number conservation constraint deforms the predictions of fragmentation observables as calculated in the grand canonical ensemble. We derive an analytical formula allowing to extract canonical results from a grand canonical calculation and vice versa. This formula shows that exact canonical results can be recovered for observables varying linearly or quadratically with the number of particles, independent of the grand canonical particle number fluctuations. We explore the validity of such grand canonical extrapolation for different fragmentation observables in the framework of the analytical Grand Canonical or Canonical Thermodynamical Model [(G)CTM] of nuclear multifragmentation. It is found that corrections to the grand canonical expectations can be evaluated with high precision, provided the system does not experience a first order phase transition. In particular, because of the Coulomb quenching of the liquid-gas phase transition of nuclear matter, we find that mass conservation corrections to the grand canonical ensemble can be safely computed for typical observables of interest in experimental measurements of nuclear fragmentation, even if deviations exist for highly exclusive observables.

description: We present a new method for completing higher derivative corrections for theories that exhibit duality symmetries under reduction. This proposal is based on the observation that duality symmetry in the reduced theory highly constrains the form of the unreduced theory. We apply this idea to closed bosonic string theory and complete the Riemann squared term to simply derive the known full tree-level effective action to order alpha'.

description: Additional file 1: Table S1. Types of marks commonly used in the literature. For quantitatively marked analysis, diameter is the most widely mark used by ecologists while plant status represents the most common qualitative mark used (Fedriani and Wiegand 2014). Table S2. Most used null models for different type of Spatial Point-Pattern Analysis. For each analysis type, the related assumption is presented. Both uni- and bivariate modes are unmarked analyses. Table S3. Some observed species spatial patterns and processes and/or factors proposed to be responsible for their creation in uni- and bivariate analyses. The nomenclature of observed patterns mentioned here are those used in the references cited. Aggregation/attraction mainly results from facilitation while regularity/repulsion is commonly related to competitive interaction.

description: The spin-transfer nano-oscillator (STNO) offers the possibility of using the transfer of spin angular momentum via spin-polarized currents to generate microwave signals. However, at present STNO microwave emission mainly relies on both large drive currents and external magnetic fields. These issues hinder the implementation of STNOs for practical applications in terms of power dissipation and size. Here, we report microwave measurements on STNOs built with MgO-based magnetic tunnel junctions having a planar polarizer and a perpendicular free layer, where microwave emission with large output power, excited at ultralow current densities, and in the absence of any bias magnetic fields is observed. The measured critical current density is over one order of magnitude smaller than previously reported. These results suggest the possibility of improved integration of STNOs with complementary metal-oxide-semiconductor technology, and could represent a new route for the development of the next-generation of on-chip oscillators.

Broken planar Skyrmions -- statics and dynamics

description: The broken planar Skyrme model is a theory that breaks global O(3) symmetry to the dihedral group D_N. It has been shown that the single soliton solution is formed of N constituent parts, named partons, that are topologically confined. The multi-soliton solutions have already been computed for N = 3 and were shown to be related to polyiamonds. We extend this for larger N and demonstrate that this polyform structure continues (planar figures formed by regular N-gons joined along their edges, of which polyiamonds are the N=3 subset). Furthermore, we numerically simulate the dynamics of this model for the first time. It will be demonstrated that the time dependent behaviour of these solutions can be broken down into the interactions of its constituent partons. The results are then compared with those of the standard planar Skyrme model.

description: A superconducting state, that induces in ${\rm GeH_{4}}$ under the pressure at 20 GPa, is being characterized by a high critical temperature $T_{C}\in<54.54,31.23>$ K, for a wide range of the Coulomb pseudopotential $μ^{\star}\in<0.1,0.3>$. Other thermodynamic parameters for the considered range of the Coulomb pseudopotential significantly differ from the predictions of a classical BCS theory. In particular: (i) the ratio of the energy gap to the critical temperature ($R_Δ\equiv 2Δ(0)/k_{B}T_{C}$) changes from 4.07 to 3.88; (ii) the value of the parameter $R_{C}\equivΔC(T_{C})/C^{N}(T_{C})$ decreases from 1.85 to 1.69, where $ΔC$ denotes the specific heat's jump, and $C^{N}$ is the specific heat of the normal state; (iii) the ratio $R_{H}\equiv T_{C}C^{N}(T_{C})/H^{2}_{C}(0)$, where $H_{C}(0)$ represents the low - temperature thermodynamic critical field, increases from 0.147 to 0.155.

Critical magnetic field in holographic superconductor in Gauss-Bonnet gravity with Born-Infeld electrodynamics

Subjects: subject: High Energy Physics - Theory (hep-th)

description: In the paper using matching method in the probe limit, we investigate some properties of holographic superconductor in Gauss-Bonnet gravity with Born-Infeld electrodynamics . We discuss the effects of the Gauss-Bonnet coupling $\a$ and Born-Infeld parameter $b$ on the critical temperature and condensate. We find that both of $\a$ and $b$ make the critical temperature decrease, which implies the condensate harder to form. Moreover we study the magnetic effect on holographic superconductor and obtain that the ratio between the critical magnetic field and the square of the critical temperature increases from zero as the temperature is lowered below the critical value $T_c$, which agrees well with the former results. We also find the critical magnetic field is indeed affected by Gauss-Bonnet coupling, but not by Born-Infeld parameter.

Changing the Body: Discourses on Sex, Gender, and Desire in the Contemporary Chinese Danmei Culture
Creators: name: Zhang, Yawed
Publisher: name: University of Chicago
Year: 2022
Subjects: subject: Danmei
subject: China
subject: Internet Culture
subject: Gender and Sexuality

description: Danmei is an emerging internet subculture in China in which young females produce writings and art about homosexual males. Adopting a feminist approach to literary criticism and media culture, this study interprets the conceptualization and representation of gender, sexuality, and identity in the field of danmei through an analysis of the two special danmei narratives, the sex reverse genre and intersex genres. In the two types of narratives, the danmei community uses the character and plot as raw materials to manipulate the sexed body. I conduct a mix of qualitative methods including ethnographic observations of the media platform, interviews, and discourse analysis of literary texts and subcultural norms to understand how the danmei community perceives the dynamics between sex, gender, and sexuality. I propose that the danmei culture establishes the narrative framework and the participatory space that allow the community to form resistance, but the contents and structure paradoxically capitulate the paradigm of the gender binary and heteronormative discourses. The analysis focuses on the gendered description of womanhood in the fictional female bodies and the disappearance of gender/queer consciousness. My study sheds light on the implications of cyberculture from the perspective of gender/queer theory and media studies. My findings demonstrate how the discourses around sex, gender, and sexuality circulate among Chinese young women’s daily consumption of literature, visual images, and media messages.
MAMPOSSt: Modelling Anisotropy and Mass Profiles of Observed Spherical Systems. I. Gaussian 3D velocities

description: Mass modelling of spherical systems through internal motions is hampered by the mass/velocity anisotropy (VA) degeneracy inherent in the Jeans equation, as well as the lack of techniques that are both fast and adaptable to realistic systems. A new fast method, called MAMPOSSt, which performs a maximum likelihood fit of the distribution of observed tracers in projected phase space, is developed and thoroughly tested. MAMPOSSt assumes a shape for the gravitational potential, but instead of postulating a shape for the distribution function in terms of energy and angular momentum, or supposing Gaussian line-of-sight velocity distributions, MAMPOSSt assumes a VA profile and a shape for the 3D velocity distribution, here Gaussian. MAMPOSSt requires no binning, differentiation, nor extrapolation of the observables. Tests on cluster-mass haloes from LambdaCDM cosmological simulations show that, with 500 tracers, MAMPOSSt is able to jointly recover the virial radius, tracer scale radius, dark matter scale radius and outer or constant VA with small bias (<10% on scale radii and <2% on the two other quantities) and inefficiencies of 10%, 27%, 48% and 20%, respectively. MAMPOSSt does not perform better when some parameters are frozen, and even worse when the virial radius is set to its true value, which appears to be the consequence of halo triaxiality. The accuracy of MAMPOSSt depends weakly on the adopted interloper removal scheme, including an efficient iterative Bayesian scheme that we introduce here, which can directly obtain the virial radius with as good precision as MAMPOSSt. Our tests show that MAMPOSSt with Gaussian 3D velocities is very competitive with, and up to 1000x faster than other methods. Hence, MAMPOSSt is a very powerful and rapid tool for the mass and anisotropy modeling of systems such as clusters and groups of galaxies, elliptical and dwarf spheroidal galaxies.

description: We survey the development of Clifford's geometric algebra and some of its engineering applications during the last 15 years. Several recently developed applications and their merits are discussed in some detail. We thus hope to clearly demonstrate the benefit of developing problem solutions in a unified framework for algebra and geometry with the widest possible scope: from quantum computing and electromagnetism to satellite navigation, from neural computing to camera geometry, image processing, robotics and beyond.
