description: Classification of skull fracture is a challenging task for both radiologists and researchers. Skull fractures result in broken pieces of bone, which can cut into the brain and cause bleeding and other injury types. So it is vital to detect and classify the fracture very early. In real world, often fractures occur at multiple sites. This makes it harder to detect the fracture type where many fracture types might summarize a skull fracture. Unfortunately, manual detection of skull fracture and the classification process is time-consuming, threatening a patient's life. Because of the emergence of deep learning, this process could be automated. Convolutional Neural Networks (CNNs) are the most widely used deep learning models for image categorization because they deliver high accuracy and outstanding outcomes compared to other models. We propose a new model called SkullNetV1 comprising a novel CNN by taking advantage of CNN for feature extraction and lazy learning approach which acts as a classifier for classification of skull fractures from brain CT images to classify five fracture types. Our suggested model achieved a subset accuracy of 88%, an F1 score of 93%, the Area Under the Curve (AUC) of 0.89 to 0.98, a Hamming score of 92% and a Hamming loss of 0.04 for this seven-class multi-labeled classification.

description: We use the EAGLE cosmological hydrodynamic simulation suite to study the specific angular momentum of galaxies, $j$, with the aims of (i) investigating the physical causes behind the wide range of $j$ at fixed mass and (ii) examining whether simple, theoretical models can explain the seemingly complex and non-linear nature of the evolution of $j$. We find that $j$ of the stars, $j_{\rm stars}$, and baryons, $j_{\rm bar}$, are strongly correlated with stellar and baryon mass, respectively, with the scatter being highly correlated with morphological proxies such as gas fraction, stellar concentration, (u-r) intrinsic colour, stellar age and the ratio of circular velocity to velocity dispersion. We compare with available observations at $z=0$ and find excellent agreement. We find that $j_{\rm bar}$ follows the theoretical expectation of an isothermal collapsing halo under conservation of specific angular momentum to within $\approx 50$%, while the subsample of rotation-supported galaxies are equally well described by a simple model in which the disk angular momentum is just enough to maintain marginally stable disks. We extracted evolutionary tracks of the stellar spin parameter of EAGLE galaxies and found that the fate of their $j_{\rm stars}$ at $z=0$ depends sensitively on their star formation and merger histories. From these tracks, we identified two distinct physical channels behind low $j_{\rm stars}$ galaxies at $z=0$: (i) galaxy mergers, and (ii) early star formation quenching. The latter can produce galaxies with low $j_{\rm stars}$ and early-type morphologies even in the absence of mergers.

Assessing Compatibility of Direct Detection Data: Halo-Independent Global Likelihood Analyses

description: We present two different halo-independent methods to assess the compatibility of several direct dark matter detection data sets for a given dark matter model using a global likelihood consisting of at least one extended likelihood and an arbitrary number of Gaussian or Poisson likelihoods. In the first method we find the global best fit halo function (we prove that it is a unique piecewise constant function with a number of down steps smaller than or equal to a maximum number that we compute) and construct a two-sided pointwise confidence band at any desired confidence level, which can then be compared with those derived from the extended likelihood alone to assess the joint compatibility of the data. In the second method we define a "constrained parameter goodness-of-fit" test statistic, whose $p$-value we then use to define a "plausibility region" (e.g. where $p \geq 10\%$). For any halo function not entirely contained within the plausibility region, the level of compatibility of the data is very low (e.g. $p < 10 \%$). We illustrate these methods by applying them to CDMS-II-Si and SuperCDMS data, assuming dark matter particles with elastic spin-independent isospin-conserving interactions or exothermic spin-independent isospin-violating interactions.

description: We construct Narain CFTs from self-dual codes on the finite field $F_p$ through even self-dual lattices for any prime $p>2$. Using this correspondence, we can relate the spectral gap and the partition function of the CFT to the error correction capability and the extended enumerator polynomial of the code. In particular, we calculate specific spectral gaps of CFTs constructed from codes and compare them with the largest spectral gap among all Narain CFTs.

description: Current large scale implementations of deep learning and data mining require thousands of processors, massive amounts of off-chip memory, and consume gigajoules of energy. Emerging memory technologies such as nanoscale two-terminal resistive switching memory devices offer a compact, scalable and low power alternative that permits on-chip co-located processing and memory in fine-grain distributed parallel architecture. Here we report first use of resistive switching memory devices for implementing and training a Restricted Boltzmann Machine (RBM), a generative probabilistic graphical model as a key component for unsupervised learning in deep networks. We experimentally demonstrate a 45-synapse RBM realized with 90 resistive switching phase change memory (PCM) elements trained with a bio-inspired variant of the Contrastive Divergence (CD) algorithm, implementing Hebbian and anti-Hebbian weight updates. The resistive PCM devices show a two-fold to ten-fold reduction in error rate in a missing pixel pattern completion task trained over 30 epochs, compared to untrained case. Measured programming energy consumption is 6.1 nJ per epoch with the resistive switching PCM devices, a factor of ~150 times lower than conventional processor-memory systems. We analyze and discuss the dependence of learning performance on cycle-to-cycle variations as well as number of gradual levels in the PCM analog memory devices.

description: SubHalo Abundance Matching (SHAM) is an empirical method for constructing galaxy catalogues based on high-resolution $N$-body simulations. We apply SHAM on the UNIT simulation to simulate SDSS BOSS/eBOSS Luminous Red Galaxies (LRGs) within a wide redshift range of $0.2 < z < 1.0$. Besides the typical SHAM scatter parameter $σ$, we include $v_{\rm smear}$ and $V_{\rm ceil}$ to take into account the redshift uncertainty and the galaxy incompleteness respectively. These two additional parameters are critical for reproducing the observed 2PCF multipoles on 5--25$\,h^{-1}\,{\rm Mpc}$. The redshift uncertainties obtained from the best-fitting $v_{\rm smear}$ agree with those measured from repeat observations for all SDSS LRGs except for the LOWZ sample. We explore several potential systematics but none of them can explain the discrepancy found in LOWZ. Our explanation is that the LOWZ galaxies might contain another type of galaxies which needs to be treated differently. The evolution of the measured $σ$ and $V_{\rm ceil}$ also reveals that the incompleteness of eBOSS galaxies decreases with the redshift. This is the consequence of the magnitude lower limit applied in eBOSS LRG target selection. Our SHAM also set upper limits for the intrinsic scatter of the galaxy--halo relation given a complete galaxy sample: $σ_{\rm int}<0.31$ for LOWZ at $0.2

description: In der Arbeit «Sexuelle Belästigung am Arbeitsplatz der Sozialen Arbeit durch Adressat:innen», einer empi-rischen Untersuchung von Meret Zeindler und Dorothee Schmid, wird anhand eines Mixed Method Designs erforscht, ob und wie sexuelle Belästigung ausgehend von Adressat:innen von Studierenden der Sozialen Arbeit erlebt wird. Aufgrund verschiedener Studienergebnisse wird davon ausgegangen, dass Studierende, welche in der Praxis tätig, aus verschiedenen Gründen einem Risiko zum Erleben von sexueller Belästigung ausgesetzt sind. Als Grundlage zur Untersuchung dieser Hypothese dienen folgende Forschungsfragen: Wird sexuelle Belästigung von Studierenden Sozialer Arbeit durch Adressat:innen am Arbeitsplatz der Sozialen Arbeit erlebt? Wie häufig und in welchen Formen wird die sexuelle Belästigung erlebt? Gibt es Zusammenhänge zwischen Arbeitsbedingungen und sexueller Belästigung? Wie werden die Erlebnisse der sexuellen Belästigung von den Betroffenen erlebt? 112 Bachelorstudierende der Sozialen Arbeit dreier Deutschweizer Fachhochschulen nahmen an der freiwilligen Befragung mittels eines teilstandardisierten Online-Fragebogens teil. 88.4% der Befragten gaben an, in den letzten fünf Jahren mindestens einmal sexuelle Belästigung durch Adressat:innen erlebt zu haben, am häufigsten in Form von verbaler sexueller Belästigung. Statistisch signifikante Zusammenhänge konnten für die Arbeitsplatzfaktoren allein arbeiten, Arbeit in Privaträumen, Wohlbefinden und Sensibilität im Team nachgewiesen werden. Persönliche Beschreibungen der Befragten unterstreichen diese quantitativen Ergebnisse.

description: A critical result in superconductivity is that flat bands, though dispersionless, can still host nonzero superfluid weight due to quantum geometry. We show that the derivation of the mean field superfluid weight in previous literature is incomplete, which can lead to severe quantitative and even qualitative errors. We derive the complete equations and demonstrate that the minimal quantum metric -- the metric with minimum trace -- is related to the superfluid weight in isolated flat bands. We complement this result with an exact calculation of the Cooper pair mass in attractive Hubbard models with the uniform pairing condition. When the orbitals are located at high symmetry positions, the Cooper pair mass is exactly given by the quantum metric, which is guaranteed to be minimal. Moreover, we study the effect of closing the band gap between the flat and dispersive bands, and develop a mean-field theory of pairing for different band-touching points via the $S$-matrix construction. In mean field, we show that a non-isolated flat band can actually be beneficial for superconductivity. This is a promising result in the search for high temperature superconductivity as the material does not need to have flat bands that are isolated from other bands by the thermal energy. Our work resolves a fundamental caveat in understanding the relation of multiband superconductivity to quantum geometry, and the results on band touchings widen the class of systems advantageous for the search of high temperature flat band superconductivity.

description: We investigate the electronic and optical properties of monolayer and stacking dependent bilayer blue phosphorus in the framework of density functional theory (DFT) and tight-binding approximations. We extract the hopping parameters of TB Hamiltonian for monolayer and bilayer blue phosphorus by using the DFT results. The variation of energy band gap with applied external electric field for two different stacks of bilayer blue phosphorus are also shown. We examine the linear response of the systems due to the external electromagnetic radiation in terms of the dielectric functions in the DFT theory. The relatively large electronic band gap and possibility of exfoliation form bulk structure due to weak interlayer coupling, make blue phosphorus an appropriate candidate for future electronic devices.

NLO QCD Renormalization Group Evolution for Non-Leptonic $ΔF=2$ Transitions in the SMEFT

description: We present for the first time NLO QCD Renormalization Group (RG) evolution matrices for non-leptonic $ΔF=2$ transitions in the Standard Model Effective Field Theory (SMEFT). To this end we transform first the known two-loop QCD anomalous dimension matrices (ADMs) of the BSM operators in the so-called BMU basis into the ones in the common Weak Effective Theory (WET) basis (the so-called JMS basis) for which tree-level and one-loop matching to the SMEFT are already known. This allows us subsequently to find the two-loop QCD ADMs for the SMEFT non-leptonic $ΔF=2$ operators in the Warsaw basis. Having all these ingredients we investigate the impact of these NLO QCD effects on the QCD RG evolution of SMEFT Wilson coefficients for non-leptonic $ΔF=2$ transitions from the new physics scale $Λ$ down to the electroweak scale $μ_\text{ew}$. The main benefit of these new contributions is that they allow to remove renormalization scheme dependences present both in the one-loop matchings between the WET and SMEFT and also between SMEFT and a chosen UV completion. But the NLO QCD effects, calculated here in the NDR scheme, turn out to be small, in the ballpark of a few percent but larger than one-loop Yukawa top effects when only the $ΔF=2$ operators are considered. The technology developed in our paper allows to obtain the ADMs in the SMEFT from the ones of the BMU basis also for non-leptonic $ΔF=1$ decays and the results of this more involved analysis will be presented soon in another publication.

description: Low-luminosity active galactic nuclei (LLAGNs) are believed to be powered by an accretion-jet model, consisting of an inner advection-dominated accretion flow (ADAF), an outer truncated standard thin disk, and a jet. But model degeneracy still exists in this framework. For example, the X-ray emission can originate from either the ADAF or jet. The aim of the present work is to check these models with the Faraday rotation measure (RM) observations recently detected for two LLAGNs, M87 and 3C 84, in the sub-mm band. For M87, we find that the RM predicted by the model in which the X-ray emission originates from the ADAF is larger than the observed upper limit of RM by over two orders of magnitude, while the model in which the X-ray emission originates from the jet predicts a RM lower than the observed upper limit. For 3C 84, the sub-mm emission is found to be dominated by the jet component, while the Faraday screen is attributed to the ADAFs. This scenario can naturally explain the observed {\it external} origin of the RM and why RM is found to be stable during a two-year interval although the sub-mm emission increases at the same period.

description: In der vorliegenden Arbeit «Bundesrahmengesetz für die Sozialhilfe – Ein Handlungsplan für Professionelle der Sozialen Arbeit zur Schaffung eines Bundesrahmengesetzes für die Sozialhilfe im politischen Prozess» geht der Autor Oliver Siegenthaler den Fragen nach, warum alle Vorstösse zur Einführung eines nationalen Rahmengesetz für die Sozialhilfe im schweizerischen Parlament bisher erfolglos waren und wie Professionelle der Sozialen Arbeit vorgehen könnten, um im politischen Prozess den Weg für die Einführung eines Rahmengesetzes zu ebnen. Sozialhilfe stellt die Menschenwürde von Bedürftigen in einer Notlage sicher und nimmt als letztes Netz eine tragende Funktion im System der sozialen Sicherheit ein. Sie ist kantonal geregelt und es herrschen teilweise beträchtliche Unterschiede bei der Ausgestaltung zwischen den Kantonen. Dies ist in Bezug auf die in der Bundesverfassung garantierte Rechtsgleichheit aller Schweizer Bürger:innen problematisch und ein Rahmengesetz würde dem Abhilfe schaffen. Eine Analyse mit Hilfe des politikwissenschaftlichen Modells des Policy Cycle zeigt, dass in den letzten Jahren alle Vorstösse für ein Rahmengesetzes in frühen Phasen des politischen Prozesses gescheitert sind. Wichtige Punkte, die zu diesem Scheitern führten, sind das mangelnde Problembewusstsein der Öffentlichkeit, die einflussreichen Kantone, die einem Rahmengesetz nicht zustimmen, und die nicht vorhandene Organisiertheit der Betroffenen. Mit Hilfe der Sozialarbeitspolitik-Methoden Politikberatung, Soziallobbying und politischer Bildung wird ein Handlungsplan vorgestellt, mit dem Professionelle der Sozialen Arbeiten diesen Punkten begegnen und dadurch auf ein Rahmengesetz hinwirken könnten.

Three levels of effective theories, increasing in precision, can be distinguished: the semiclassical theory given by the Vlasov equation, the mean-field theory given by the Hartree-Fock equation, and the description of the dominant effects of non-trivial entanglement by the random phase approximation. Particular attention is given to the discussion of admissible initial data, and I present an example of a realistic quantum quench that can be approximated by Hartree-Fock dynamics.

description: Librational motion, whereby a rigid body undergoes angular oscillation around a preferred direction, can be observed in optically trapped, silica microspheres. We demonstrate the cooling of one librational degree of freedom for $\sim 5~μ$m diameter spheres that have been induced to rotate with an external electric field coupled to their electric dipole moment. Cooling is accomplished by adding a phase modulation to the rotating field. The degree of cooling is quantified by applying a $π/2$ shift to the phase of the electric field and fitting the resulting exponential decay of the librational motion to obtain a damping time, as well as estimating a mode temperature from the observed libration in equilibrium. The result is an important step in the study of the dynamics of trapped microspheres, crucial to cooling the mechanical motion to its ground state, as well as providing insights regarding the charge mobility in the material at microscopic scales.

description: China Space Station Telescope (CSST) is a forthcoming powerful Stage IV space-based optical survey equipment. It is expected to explore a number of important cosmological problems in extremely high precision. In this work, we focus on investigating the constraints on neutrino mass and other cosmological parameters under the model of cold dark matter with a constant equation of state of dark energy ($w$CDM), using the mock data from the CSST photometric galaxy clustering and cosmic shear surveys (i.e. 3$\times$2pt). The systematics from galaxy bias, photometric redshift uncertainties, intrinsic alignment, shear calibration, baryonic feedback, non-linear, and instrumental effects are also included in the analysis. We generate the mock data based on the COSMOS catalog considering the instrumental and observational effects of the CSST, and make use of the Markov Chain Monte Carlo (MCMC) method to perform the constraints. Comparing to the results from current similar measurements, we find that CSST 3$\times$2pt surveys can improve the constraints on the cosmological parameters by one order of magnitude at least. We can obtain an upper limit for the sum of neutrino mass $Σm_ν \lesssim 0.36$ (0.56) eV at 68\% (95\%) confidence level, and $Σm_ν \lesssim 0.23$ (0.29) eV at 68\% (95\%) confidence level if ignore the baryonic effect, which is comparable to the {\it Planck} results and much better than the current photometric surveys. This indicates that the CSST photometric surveys can provide stringent constraints on the neutrino mass and other cosmological parameters, and the results also can be further improved by including data from other kinds of CSST cosmological surveys.

description: In these introductory lectures we discuss the topic of Yangian symmetry from various perspectives. Forming the classical counterpart of the Yangian and an extension of ordinary Noether symmetries, first the concept of nonlocal charges in classical, two-dimensional field theory is reviewed. We then define the Yangian algebra following Drinfeld's original motivation to construct solutions to the quantum Yang-Baxter equation. Different realizations of the Yangian and its mathematical role as a Hopf algebra and quantum group are discussed. We demonstrate how the Yangian algebra is implemented in quantum, two-dimensional field theories and how its generators are renormalized. Implications of Yangian symmetry on the two-dimensional scattering matrix are investigated. We furthermore consider the important case of discrete Yangian symmetry realized on integrable spin chains. Finally we give a brief introduction to Yangian symmetry in planar, four-dimensional super Yang-Mills theory and indicate its impact on the dilatation operator and tree-level scattering amplitudes. These lectures are illustrated by several examples, in particular the two-dimensional chiral Gross-Neveu model, the Heisenberg spin chain and N=4 superconformal Yang-Mills theory in four dimensions. This review arose from lectures given at the Young Researchers Integrability School at Durham University (UK).

title: Universal Health Coverage zwischen unbewusster Implementierung und Informationsmangel
Creators: name: Schlögl, Helene
Year: 2023

description: Die vorliegende Masterarbeit untersucht die Implementierung von Universal Health Coverage (UHC) in von Österreich öffentlich geförderten Entwicklungszusammenarbeits-Projekten zur Aus-, Fort- und Weiterbildung von Gesundheitsfachpersonal. Als Teil der Sustainable Development Goals (SDG3.8) strebt UHC an, dass alle Menschen weltweit ungehindert Zugang zu leistbarer und qualitativ hochwertiger Gesundheitsversorgung haben, wofür auch ausreichend und angemessen ausgebildete Gesundheitsfachkräfte notwendig sind. Ziel dieser Arbeit ist es daher zu untersuchen, ob bzw. inwiefern UHC in von der Austrian Development Agency geförderten Projekten, die Maßnahmen zur Aus-, Fort- oder Weiterbildung von Gesundheitsfachpersonal beinhalten, implementiert wird. Damit zusammenhängend wird auch erörtert, welche Faktoren den Implementierungsprozess beeinflussen und welchen Beitrag die Projekte letztendlich zum Erreichen von UHC leisten können. Als theoretischer Anknüpfungspunkt der Forschung dienen dabei ausgewählte Policy-Implementierungstheorien. Die Datenerhebung erfolgt mittels leitfadengestützten Expert*inneninterviews, in denen Projektverantwortliche von acht in Frage kommenden Projekten befragt werden. Die Auswertung der Daten erfolgt in Form einer qualitativen Inhaltsanalyse auf Basis eines eigens erarbeiteten Kategoriensystems. Zentrale Erkenntnis der Forschung ist, dass die Projekte zwar zum Erreichen von UHC beitragen, die Implementierung von SDG3.8 aufgrund von Informations- und Ressourcenmangel aber vorrangig unbewusst geschieht, wodurch Potentiale teilweise ungenutzt bleiben.
description: This Master's thesis examines the implementation of Universal Health Coverage (UHC) in development cooperation projects publicly funded by the Austrian state that take measures on the education and training of health professionals. As part of the Sustainable Development Goals (SDG3.8), UHC aims to ensure that all people worldwide have unrestricted access to affordable and high-quality health care, which also requires a sufficient and appropriately trained health workforce. Therefore, the aim of this study is to examine whether and how UHC is implemented in projects funded by the Austrian Development Agency that include measures for the education or training of health professionals. In addition, factors influencing the implementation process as well as the examined projects’ ability to contribute to achieving UHC are analysed. Selected policy implementation theories serve as a theoretical starting point for the research. Guideline-based expert interviews with project leaders of eight projects in question are used for the data collection. The data analysis is carried out using a qualitative content analysis based on a specially developed system of categories. The research’s central finding is that while the projects contribute to UHC, the implementation of SDG3.8 happens primarily unconsciously due to a lack of information and resources, causing that some potential remain unused.
LTM: scalable and black-box similarity-based test suite minimization based on language models

description: Test suites tend to grow when software evolves, making it often infeasible to execute all test cases with the allocated testing budgets, especially for large software systems. Test suite minimization (TSM) is employed to improve the efficiency of software testing by removing redundant test cases, thus reducing testing time and resources while maintaining the fault detection capability of the test suite. Most existing TSM approaches rely on code coverage (white-box) or model-based features, which are not always available to test engineers. Recent TSM approaches that rely only on test code (black-box) have been proposed, such as ATM and FAST-R. The former yields higher fault detection rates (FDR) while the latter is faster. To address scalability while retaining a high FDR, we propose LTM (Language modelbased Test suite Minimization), a novel, scalable, and black-box similarity-based TSM approach based on large language models (LLMs), which is the first application of LLMs in the context of TSM. To support similarity measurement using test method embeddings, we investigate five different pre-trained language models: CodeBERT, GraphCodeBERT, UniXcoder, StarEncoder, and CodeLlama, on which we compute two similarity measures: Cosine Similarity and Euclidean Distance. Our goal is to find similarity measures that are not only computationally more efficient but can also better guide a Genetic Algorithm (GA), which is used to search for optimal minimized test suites, thus reducing the overall search time. Experimental results show that the best configuration of LTM (UniXcoder/Cosine) outperforms ATM in three aspects: (a) achieving a slightly greater saving rate of testing time (41.72% versus 41.02%, on average); (b) attaining a significantly higher fault detection rate (0.84 versus 0.81, on average); and, most importantly, (c) minimizing test suites nearly five times faster on average, with higher gains for larger test suites and systems, thus achieving much higher scalability.

description: In a lossless periodic structure, a bound state in the continuum (BIC) is characterized by a real frequency and a real Bloch wavevector for which there exist waves propagating to or from infinity in the surrounding media. For applications, it is important to analyze the high-$Q$ resonances that either exist naturally for wavevectors near that of the BIC or appear when the structure is perturbed. Existing theories provide quantitative results for the complex frequency (and the $Q$-factor) of resonant modes that appear/exist due to structural perturbations or wavevector variations. When a periodic structure is regarded as a periodic waveguide, eigenmodes are often analyzed for a given real frequency. In this paper, we consider periodic waveguides with a BIC, and study the eigenmodes for given real frequencies near the frequency of the BIC. It turns out that such eigenmodes near the BIC always have a complex Bloch wavenumber, but they may or may not be leaky modes that radiate out power laterally to infinity. These eigenmodes can also be complex modes that decay exponentially in the lateral direction. Our study is relevant for applications of BICs in optical waveguides, and it is also helpful for analyzing photonic devices operating near the frequency of a BIC.

description: Das Risiko an einem Burnout zu erkranken ist bei Fachpersonen der Sozialen Arbeit (SA) im Vergleich zur Gesamtbevölkerung erhöht. Demnach befasst sich die vorliegende Bachelorarbeit mit dem Thema Selbstfürsorge. Spezifisch interessieren sich die Autorinnen dafür, wie die Selbstfürsorge von Studierenden, die ein Praktikum absolvieren und/oder einer beruflichen Tätigkeit im sozialen Bereich nachgehen, gefördert werden kann. Diese Hauptfrage wird durch eine Literaturanalyse und zwei empirische Teile beantwortet. Die Online-Umfrage (n= 242, erster empirischer Teil) mit Studierenden beschäftigte sich mit dem Bewusstsein für das Thema und mit angewandten Methoden / Unterstützungsangeboten. Expert*inneninterviews (zweiter empirischer Teil) untersuchten, was Fachpersonen empfehlen. In Folge sind beide Ergebnisse diskutiert und verknüpft worden sowie ein Handlungswissen für die SA wurde abgeleitet. Die Ergebnisse der Online-Umfrage zeigten, dass 99% der Befragten bewusst etwas für ihre Selbstfürsorge unternehmen und vielfältige Methoden / Unterstützungsangebote anwenden. Die Mehrfachbelastung stellte für die Zielgruppe ein durchgehendes Thema dar. Die Interviews ergaben, dass Fachpersonen Studierenden individuell bei der Findung einer optimalen Strategie für die Selbstfürsorge unterstützen. Aus der Literaturanalyse geht hervor, dass aus berufsethischer Perspektive die Selbstfürsorge grösstenteils in der Selbstverantwortung der angehenden Fachpersonen liegt. Die multifaktorielle Sichtweise deutet zudem darauf hin, dass auch weitere Akteur*innen einen wichtigen Beitrag zur Selbstfürsorge der Zielgruppe leisten können.

description: We present the minimal realization of the $\ell$-conformal Galilei group in 2+1 dimensions on a single complex field. The simplest Lagrangians yield the complex Pais-Uhlenbeck oscillator equations. We introduce a minimal deformation of the $\ell$=1/2 conformal Galilei (a.k.a. Schrödinger) algebra and construct the corresponding invariant actions. Based on a new realization of the d=1 conformal group, we find a massive extension of the near-horizon Kerr-dS/AdS metric.

Chiral fermions, dimensional regularization, and the trace anomaly

description: We investigate the trace anomaly of a chiral fermion in dimensional regularization, considering in detail the simplest case of coupling to an abelian gauge field. We apply the Breitenlohner-Maison/'t Hooft-Veltman prescription for dealing with the chiral matrix $γ^5$ and verify that no parity-odd term arises in the trace anomaly. The issue treated here is analogous to that of a chiral fermion in curved spacetime, discussed in recent literature. The advantage of having a simplified background minimizes the amount of algebraic calculations and allows pinpointing better the subtle points carried by dimensional regularization.
