description: Astrophysical accretion is arguably the most prevalent physical process in the Universe; it occurs during the birth and death of individual stars and plays a pivotal role in the evolution of entire galaxies. Accretion onto a black hole, in particular, is also the most efficient mechanism known in nature, converting up to 40% of accreting rest mass energy into spectacular forms such as high-energy (X-ray and gamma-ray) emission and relativistic jets. Whilst magnetic fields are thought to be ultimately responsible for these phenomena, our understanding of the microphysics of MHD turbulence in accretion flows as well as large-scale MHD outflows remains far from complete. We present a new theoretical model for astrophysical disk accretion which considers enhanced vertical transport of momentum and energy by MHD winds and jets, as well as transport resulting from MHD turbulence. We also describe new global, 3D simulations that we are currently developing to investigate the extent to which non-ideal MHD effects may explain how small-scale, turbulent fields (generated by the magnetorotational instability -- MRI) might evolve into large-scale, ordered fields that produce a magnetized corona and/or jets where the highest energy phenomena necessarily originate.

Die Krise als Führungsaufgabe: Krisenbewältigung und Krisenkommunikation in den einzelnen Phasen einer Krise

Publisher: name: Zenodo
Year: 2019

description: Die vorliegende Arbeit im Rahmen des MAS Management im Sozial- und Gesundheitswesen 2018 – 2020 beschäftigt sich mit der Krise als Führungsaufgabe. In einem ersten Teil werden die theoretischen Grundlagen erarbeitet. Auf Grund der Begriffsdefinition wird das Thema genauer abgegrenzt. Die Einteilung von Krisen erfolgt als Grundlage in verschiedene Arten und die typischen Phasen. Dabei werden diverse Ansätze aus der Literatur verglichen. Ein ausgewähltes Krisenverlaufsmodell, welches auch in der Praxis anwendbar ist, wird im Detail beschrieben. Es soll ermöglichen, einen strukturierten Überblick über das komplexe Thema Krise zu erhalten. Bei der Erarbeitung der Theorie fiel immer wieder ein Wort auf: Kommunikation. Diesem wichtigen Element in zwischenmenschlichen Beziehungen wird daher ein separates Kapitel gewidmet. Dabei wird die Kommunikation von verschiedenen Seiten beleuchtet und diverse Aspekte, welche eine zentrale Rolle spielen, im Hinblick auf eine Krisensituation aufgegriffen. Insbesondere werden Regeln für eine gute Krisenkommunikation erarbeitet und es werden Ansätze für Kommunikationsstrategien erläutert. Dabei wird auf die wichtigsten Punkte explizit eingegangen, nämlich die Zielgruppen, der Zeitpunkt und die Kommunikationskanäle. Zum Schluss wird noch das Thema Umgang mit Medien im Speziellen angeschaut. In einem dritten Teil wird ein selbst erlebtes Praxisbeispiel beschrieben. Es erfolgt die Gegenüberstellung von Theorie und Praxis an diesem Vorfall. So werden die in den theoretischen Grundlagen erarbeiteten Phasen am ausgewählten Modell für das konkrete Praxisbeispiel durchgespielt. Dabei kommt sehr schön zum Vorschein, wie man auf eine Krise bei der Sparkasse Schwyz AG vorbereitet ist und wie man den beschrieenen Vorfall bewältigt hat. Als Ergänzung und Aktualität für den gewählten Fall werden der psychologischen Komponente, welche eine wichtige Rolle spielt, besondere Aufmerksamkeit geschenkt. Insbesondere finden die Themen Tod und Trauer, wenn auch immer noch verbreitet Tabuthemen, in dieser Arbeit ihren Platz. Interessant sind die Erkenntnisse für den täglichen Gebrauch, welche daraus resultieren. Dabei wird auch auf den Umgang mit Tod und Trauer in einer Organisation und am Arbeitsplatz eingegangen. Da sind sie noch ein viel grösseres Tabu als sie es im privaten Bereich schon sind. Die insgesamt gewonnenen Erkenntnisse werden im letzten Teil zusammengefasst. Es konnten einige Empfehlungen und Verbesserungsvorschläge eingebracht werden. Inwieweit die Theorie praxistauglich ist oder sein wird und auch umgesetzt werden kann, wird sich zeigen.

description: We consider chiral perturbation theory (ChPT) with a non-zero theta term. Due to the CP violating term, the vacuum of chiral fields is shifted to a non-trivial element on the SU(N_f) group manifold. The CP violation also provides mixing of different CP eigenstates, between scalar and pseudoscalar, or vector and axialvector operators. We investigate upto O(theta^2) effects on the mesonic two point correlators of ChPT to the one-loop order. We also address the effects of fixing topology, by using saddle point integration in the Fourier transform with respect to theta.

description: In this study we derive a single-particle equation of motion, from first-principles, starting out with a microscopic description of a tracer particle in a one-dimensional many-particle system with a general two-body interaction potential. Using a new harmonization technique, we show that the resulting dynamical equation belongs to the class of fractional Langevin equations, a stochastic framework which has been proposed in a large body of works as a means of describing anomalous dynamics. Our work sheds light on the fundamental assumptions of these phenomenological models.

description: This article studies the generalized method of moment estimation of semiparametric varying coefficient partially linear spatial autoregressive model. The technique of profile least squares is employed and all estimators have explicit formulas which are computationally convenient. We derive the limiting distributions of the proposed estimators for both parametric and non parametric components. Variable selection procedures based on smooth-threshold estimating equations are proposed to automatically eliminate irrelevant parameters and zero varying coefficient functions. Compared to the alternative approaches based on shrinkage penalty, the new method is easily implemented. Oracle properties of the resulting estimators are established. Large amounts of Monte Carlo simulations confirm our theories and demonstrate that the estimators perform reasonably well in finite samples. We also apply the novel methods to an empirical data analysis.

Nonperturbative and spin effects in the central exclusive production of tensor $χ_c(2^+)$ meson

description: We discuss central exclusive production (CEP) of the tensor $χ_c(2^{+})$ meson in proton-(anti)proton collisions at Tevatron, RHIC and LHC energies. The amplitude for the process is derived within the $k_t$-factorisation approach. Differential and total cross sections are calculated for several unintegrated gluon distributions (UGDFs). We compare exclusive production of all charmonium states $χ_c(0^+),\,χ_c(1^+)$ and $χ_c(2^+)$. Equally good description of the recent Tevatron data is achieved both with Martin-Ryskin phenomenological UGDF and UGDF based on unified BFKL-DGLAP approach. Unlike for Higgs production, the main contribution to the diffractive amplitude of heavy quarkonia comes from nonperturbative region of gluon transverse momenta $Q_{\perp}<1\,\GeV$. At $y \approx$ 0, depending on UGDF we predict the contribution of $χ_c(1^+,2^+)$ to the $J/Ψ+ γ$ channel to be comparable or larger than that of the $χ_c(0^+)$ one. This is partially due to a significant contribution from lower polarization states $λ=0$ for $χ_c(1^+)$ and $λ=0,\,\pm 1$ for $χ_c(2^+)$ meson. Corresponding theoretical uncertainties are discussed.

Magnetic field delocalization and flux inversion in fractional vortices in two-component superconductors

description: We demonstrate that, in contrast to the single-component Abrikosov vortex, in two-component superconductors vortex solutions with exponentially screened magnetic field exist only in exceptional cases: in the case of vortices carrying an integer number of flux quanta, and in a special parameter limit for half-quantum vortices. For all other parameters the vortex solutions have delocalized magnetic field with a slowly decaying tail. Furthermore, we demonstrate a new effect which is generic in two-component systems but has no counterpart in single-component systems: on exactly half of the parameter space of the $U(1)\times U(1)$ Ginzburg-Landau model, the magnetic field of a generic fractional vortex inverts its direction at a certain distance from the vortex core.

Hall coefficient and resistivity of thin films of antimony and bismuth prepared by distillation
Creators: name: Leverton, Walter Frederick
Publisher: name: University of British Columbia
Year: 2012

description: An apparatus lias been constructed to measure the Hall coefficient in metals and semi-conductors by an a.c. method. The a.c. method completely eliminates the Ettingshausen effect which in many cases introduces a considerable correction to Hall voltages measured by d.c. methods. In addition, a small alternating voltage is more easily amplified and measured than a direct voltage of similar magnitude. An apparatus has been devised for the preparation of very pure metal films by evaporation. This apparatus eliminates such sources of contamination as hot filaments. The effect of annealing on both Hall coefficient and resistivity of evaporated films of antimony and bismuth has been examined and a qualitative explanation based on the electron theory of metals is presented. The Hall coefficient of unannealed antimony films is +0.216 c.g.s.m. and of annealed films is +0.244 c.g.s.m. with an accuracy of 1 percent. Previous observers using d.c. methods found values ranging from +0.12 to +0.22 c.g.s.m. The Hall coefficient of bismuth films depends on the film thickness. It is of the order of 1 c.g.s.m.

description: We prove uniqueness theorems for asymptotically flat, stationary, extremal, vacuum black hole solutions, in four and five dimensions with one and two commuting rotational Killing fields respectively. As in the non-extremal case, these problems may be cast as boundary value problems on the two dimensional orbit space. We show that the orbit space for solutions with one extremal horizon is homeomorphic to an infinite strip, where the two boundaries correspond to the rotational axes, and the two asymptotic regions correspond to spatial infinity and the near-horizon geometry. In four dimensions this allows us to establish the uniqueness of extremal Kerr amongst asymptotically flat, stationary, rotating, vacuum black holes with a single extremal horizon. In five dimensions we show that there is at most one asymptotically flat, stationary, extremal vacuum black hole with a connected horizon, two commuting rotational symmetries and given interval structure and angular momenta. We also provide necessary and sufficient conditions for four and five dimensional asymptotically flat vacuum black holes with the above symmetries to be static (valid for extremal, non-extremal and even non-connected horizons).

description: The diet of the Great Grey Shrike Lanius excubitor during the non-breeding period was assessed using analysis of pellets and larders. The two methods gave different results but together showed a preference for voles, crickets and dung beetles. To describe the diet composition of the Great Grey Shrike based on analyses of the contents of pellets and larders; to compare the two methods, and to compare prey taken in relation to its local availability. The research was carried out during the non-breeding period of the Great Grey Shrike in an agricultural landscape of east-central Poland in 2014–2018. The diet was assessed through the analysis of the contents of larders and regurgitated pellets. The abundance of potential prey was assessed with pitfall traps for invertebrates and live traps for small mammals. In larders, the ratio of vertebrates to invertebrates was 34.3 : 65.7 (n = 528 prey items), with Orthoptera, Coleoptera and Rodentia predominant. In pellets, the ratio was 64.6 : 35.4 (n = 237 prey items in 155 pellets), with Rodentia and Coleoptera being most numerous. The proportions of the most frequently found prey taxa diﬀered signiﬁcantly between the two methods of diet analysis. In relation to potential prey availability, Great Grey Shrikes showed a preference for Common Voles Microtus arvalis but seemed to avoid mice Apodemus spp. and Diptera. The greatest discrepancies between the methods were for Coleoptera, Lepidoptera and Orthoptera. The results of the pellet and larder analyses differed, mainly because of the large number of Orthoptera found in the larders; shrikes can use them to mark their territories and so they may remain uneaten. Both analytical methods should be used simultaneously to determine the diet composition.

description: The energy-dependence of the anisotropy (the anisotropy energy spectrum) of the large-scale diffuse gamma-ray background can reveal the presence of multiple source populations. Annihilating dark matter in the substructure of the Milky Way halo could give rise to a modulation in the anisotropy energy spectrum of the diffuse gamma-ray emission measured by Fermi, enabling the detection of a dark matter signal. We determine the detectability of a dark-matter-induced modulation for scenarios in which unresolved blazars are the primary contributor to the measured emission above ~1 GeV and find that in some scenarios pair-annihilation cross sections of order the value expected for thermal relic dark matter can produce a detectable feature. We anticipate that the sensitivity of this technique to specific dark matter models could be improved by tailored likelihood analysis methods.

description: We investigate the influence of electron-phonon interactions on the dynamical properties of a quantum-dot-cavity QED system. We show that non-Markovian effects in the phonon reservoir lead to strong changes in the dynamics, arising from photon-assisted dephasing processes, not present in Markovian treatments. A pronounced consequence is the emergence of a phonon induced spectral asymmetry when detuning the cavity from the quantum-dot resonance. The asymmetry can only be explained when considering the polaritonic quasi-particle nature of the quantum-dot-cavity system. Furthermore, a temperature induced reduction of the light-matter coupling strength is found to be relevant in interpreting experimental data, especially in the strong coupling regime.

description: From sparse descriptions of events, observers can make systematic and nuanced predictions of what emotions the people involved will experience. We propose a formal model of emotion prediction in the context of a public high-stakes social dilemma. This model uses inverse planning to infer a person’s beliefs and preferences based on their action, including social preferences for equity and for maintaining a good reputation. The model then combines these inferred mental contents with the outcome to compute ‘appraisals’: whether the outcome conformed to the expectations and fulfilled the preferences. We learn functions mapping computed appraisals to emotion labels, allowing the model to match human observers’ quantitative predictions of 20 emotions, including joy, relief, guilt and envy. Model comparison indicates that inferred monetary preferences are not sufficient to explain observers’ emotion predictions; inferred social preferences are factored into predictions for nearly every emotion. The model can also account for the flexibility of emotion attributions: both human observers and the model consistently use minimal individualizing information to adjust predictions of how different people will respond to the same event. Thus, our framework integrates inverse planning, event appraisals and emotion concepts in a single computational model, to reverse-engineer people’s intuitive theory of emotions.This article is part of a discussion meeting issue ‘Cognitive artificial intelligence’.

description: We recap the main features of Minimal Dark Matter (MDM) and assess its status in the light of the recent experimental data. The theory selects an electroweak 5-plet with hypercharge Y=0 as a fully successful DM candidate, automatically stable against decay and with no free parameters: DM is a fermion with a 9.6 TeV mass. The direct detection cross-section, predicted to be 10^-44 cm2, is within reach of next-generation experiments. DM is accompanied by a charged fermion 166 MeV heavier: we discuss how it might manifest. Thanks to an electroweak Sommerfeld enhancement of more than 2 orders of magnitude, DM annihilations into W+W- give, in presence of a modest astrophysical boost factor, a positron flux compatible with the PAMELA excess (but not with the ATIC hint for a peak: MDM instead predicts a quasi-power-law spectrum), a anti-proton flux concentrated at energies above 100 GeV, and to photon fluxes comparable with present limits, depending on the DM density profile.
