description: Radio emission from magnetars provides a unique probe of the relativistic, magnetized plasma within the near-field environment of these ultra-magnetic neutron stars. The transmitted waves can undergo birefringent and dispersive propagation effects that result in frequency-dependent conversions of linear to circularly polarized radiation and vice-versa, thus necessitating classification when relating the measured polarization to the intrinsic properties of neutron star and fast radio burst (FRB) emission sites. We report the detection of such behavior in 0.7-4 GHz observations of the P = 5.54 s radio magnetar XTE J1810$-$197 following its 2018 outburst. The phenomenon is restricted to a narrow range of pulse phase centered around the magnetic meridian. Its temporal evolution is closely coupled to large-scale variations in magnetic topology that originate from either plastic motion of an active region on the magnetar surface or free precession of the neutron star crust. Our model of the effect deviates from simple theoretical expectations for radio waves propagating through a magnetized plasma. Birefringent self-coupling between the transmitted wave modes, line-of-sight variations in the magnetic field direction and differences in particle charge or energy distributions above the magnetic pole are explored as possible explanations. We discuss potential links between the immediate magneto-ionic environments of magnetars and those of FRB progenitors.

Coupling of Branes and Twisted Self-Duality in the Maxwell-Chern-Simons Theory

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

description: We study three approaches to electric-magnetic duality in the 4-dimensional Maxwell theory coupled to a dyonic point charge and in the 5-dimensional Maxwell-Chern-Simons (MCS) theory coupled to an electric point charge and a magnetic string charge. The three approaches have been developed by Dirac, Bunster and Henneaux, and Pasti, Sorokin and Tonin (PST). In Dirac's formulation, the electric magnetic duality is realized only on the level of the equations of motion. The other two formulations introduce a dual (magnetic) gauge potential to induce manifest twisted self-duality in the action. In particular, we study the relations connecting the three approaches. The main results of this paper are the Bunster-Henneaux and PST formulations of the MCS theory with sources. We compare our result to the PST formulation of 11-dimensional supergravity coupled to the M2- and M5-brane by Bandos, Berkovits, and Sorokin.

description: We show that a mass-varying neutrino model driven by scalar field dark energy relaxes the existing upper bound on the current neutrino mass to ${\sum m_ν< 0.72}$ eV. We extend the standard $Λ$ cold dark matter model by introducing two parameters: the rate of change of the scalar field with the number of $e$-folds and the coupling between neutrinos and the field. We investigate how they affect the matter power spectrum, the cosmic microwave background anisotropies and its lensing potential. The model is tested against Planck observations of temperature, polarization, and lensing, combined with baryon acoustic oscillation measurements that constrain the background evolution. The results indicate that small couplings favor a cosmological constant, while larger couplings favor a dynamical dark energy, weakening the upper bound on current neutrino masses.

title: „Für dich kein Einlass“ - Der kinorechtliche Jugendschutz in Österreich
Creators: name: Moser, Monika
Year: 2012

description: Diese Diplomarbeit verfolgt das Ziel, auf die derzeitige rechtliche Situation des österreichischen kinorechtlichen Jugendschutzes und damit verbundenden problematische Regelungen aufmerk-sam zu machen. Nach der Darstellung der historischen gesetzlichen Entwicklung und Definitio-nen zu Begriffen von „Kind“ und „Jugendlicher“ erforscht diese Arbeit, basierend auf der Recher-che einschlägiger Fachliteratur und e-mail - basierten Anfragen an Experten, wie die österreichi-sche Rechtslage aufgebaut ist. Auffallend war dabei der noch immer vorherrschende Föderalis-mus, der dazu führt, dass dieses Rechtsgebiet nach wie vor äußerst unübersichtlich ist und so eine Akzeptanz derer, die diese Regeln befolgen müssen, fraglich ist. Mit der Jugendmedien-kommission beim Bundesministerium für Unterricht, Kunst und Kultur wurde immerhin eine Institution geschaffen, die fachlich kompetent Kinofilme prüft und eine Altersgrenze festsetzt, ab welcher ein Film im Kino von Kindern und Jugendlichen besucht werden darf. Diese an sich nicht verbindliche Altersfreigabe wird heute dennoch grundsätzlich von den meisten Bundesländern übernommen und schafft somit eine Quasi-Vereinheitlichung in der Freigabepraxis. Wesentlich für die Frage, ab wann welche Filme für welches Alter geeignet sind, ist dabei eine Frage der Medienwahrnehmung und der Entwicklung von Medienkompetenz. Anhand der Darlegung der verschiedenen Theorien in diesen Bereich wird klar, dass eine eindeutige Antwort auf diese Frage nicht möglich ist. Ausgehend vom Medienkompetenzmodell von Dieter Baacke ist die Individualität jedes Menschen zu berücksichtigen und sind zahlreiche andere Faktoren, wie Eltern, Bildungsanstalten oder „peer groups“, gefordert, die Entwicklung von Kindern und Jugendlichen entsprechend ihrer Bedürfnisse zu fördern. Die vorliegende Arbeit kam dabei zum Ergebnis, dass es bereits eine Vielzahl von Einrichtungen und politischen Bestrebungen gibt, die darauf abzielen, für die heutige Jugend ihrer Entwicklung entsprechende Entwicklungsmöglichkeiten zu bieten. Nach einem kurzen Überblick über die Bewertungspraxis anderer europäischer Länder kritisiert die vorliegende Arbeit die bestehenden jugendschutzrechtlichen Regelungen. Dies vor allem im Hinblick darauf, dass es immer wieder Vorstöße einzelner Politiker und Bewegungen gibt, die sich für eine Vereinheitlichung des österreichischen Jugendschutzes aussprechen, jedoch immer wieder an den Interessen einzelner Länder scheitern. Vermisst wird die Einrichtung einer verbindlichen Bewertungskommission und Vereinheitlichung der Rechtslage, um in diesem so wichigen Bereich Rechtssicherheit für Kinder und Jugendliche bieten zu können.

description: Inclusive production processes will be important for the first observations of $XYZ$ states at new generation electron-hadron colliders, as they generally benefit from larger cross sections than their exclusive counterparts. We make predictions of semi-inclusive photoproduction of the $χ_{c1}(1P)$ and $X(3872)$, whose peripheral production is assumed to be dominated by vector exchanges. We validate the applicability of Vector Meson Dominance in the axial-vector charmonium sector and calculate production rates at center-of-mass energies relevant for future experimental facilities. We find the semi-inclusive cross sections near threshold to be enhanced by a factor of $\sim 2-3$ compared to the exclusive reaction and well suited for a first observation in photoproduction.

description: Variational Inference (VI) is a commonly used technique for approximate Bayesian inference and uncertainty estimation in deep learning models, yet it comes at a computational cost, as it doubles the number of trainable parameters to represent uncertainty. This rapidly becomes challenging in high-dimensional settings and motivates the use of alternative techniques for inference, such as Monte Carlo Dropout (MCD) or Spectral-normalized Neural Gaussian Process (SNGP). However, such methods have seen little adoption in survival analysis, and VI remains the prevalent approach for training probabilistic neural networks. In this paper, we investigate how to train deep probabilistic survival models in large datasets without introducing additional overhead in model complexity. To achieve this, we adopt three probabilistic approaches, namely VI, MCD, and SNGP, and evaluate them in terms of their prediction performance, calibration performance, and model complexity. In the context of probabilistic survival analysis, we investigate whether non-VI techniques can offer comparable or possibly improved prediction performance and uncertainty calibration compared to VI. In the MIMIC-IV dataset, we find that MCD aligns with VI in terms of the concordance index (0.748 vs. 0.743) and mean absolute error (254.9 vs. 254.7) using hinge loss, while providing C-calibrated uncertainty estimates. Moreover, our SNGP implementation provides D-calibrated survival functions in all datasets compared to VI (4/4 vs. 2/4, respectively). Our work encourages the use of techniques alternative to VI for survival analysis in high-dimensional datasets, where computational efficiency and overhead are of concern.

description: Das Forschungsprojekt DigULeLe – Digitale Ungleichheit in Lehre und Lernen. Pädagogische und mediendidaktische Entwicklung und Weiterentwicklung digitaler Konzepte und Maßnahmen zum Abbau digitaler Barrieren (DigULeLe) entstand im Zuge der Digitalisierungsstrategie der Hochschule für Angewandte Wissenschaften Hamburg (HAW Hamburg) in Kooperation der Departments „Pflege & Management“ und „Soziale Arbeit“ der Fakultät Wirtschaft und Soziales. Das Projekt befasste sich mit den unterschiedlichen Barrieren, die im Zuge der Digitalisierung der Hochschulbildung für das Lehren und Lernen entstehen können und damit die Entwicklung von digitaler Ungleichheit begünstigen. Unter Einbezug der Studierenden und Lehrenden der Departments „Pflege und Management“ und „Soziale Arbeit“ wurden konkrete digitale Barrieren identifiziert und untersucht; ein besonderes Augenmerk lag in diesem Zusammenhang auf dem Aspekt der Diversität, denn Grundlage für die Projektidee war die Annahme, dass die Dimensionen der Diversitätsmerkmale wie Alter, sozio-ökonomischer Status oder Geschlecht im Kontext von Hochschule die Teilhabe an der digitalisierten Bildungswelt unterstützen, aber auch erschweren können. In dieser Handreichung finden sich die Forschungsergebnisse, welche dazu beitragen sollen, digitale Barrieren zu verringern und den Umgang mit den Herausforderungen, welche die Digitalisierung von Lehren und Lernen mit sich bringt, teilhabeorientiert gestalten zu können. Dafür wurden Handlungsempfehlungen erarbeitet, deren Ziel es ist, digitale Kompetenzen bei Lehrenden und Lernenden zu fördern und sie im Umgang mit digitalen Barrieren zu stärken; darauf aufbauend können die Rahmenbedingungen für das digitale Lehren und Lernen verbessert, pädagogische Konzepte zur Verringerung der Barrieren aufgestellt und mediendidaktische Umsetzungsstrategien (weiter)entwickelt werden.

description: Magnetohydrodynamic turbulence drives the central engine of post-merger remnants, potentially powering both a nucleosynthetically active disk wind and the relativistic jet behind a short gamma ray burst. We explore the impact of the magnetic field on this engine by simulating three post-merger black hole accretion disks using general relativistic magnetohydrodynamics with Monte Carlo neutrino transport, in each case varying the initial magnetic field strength. We find increasing ejecta masses associated with increasing magnetic field strength. We find that a fairly robust main r -process pattern is produced in all three cases, scaled by the ejected mass. Changing the initial magnetic field strength has a considerable effect on the geometry of the outflow and hints at complex central engine dynamics influencing lanthanide outflows. We find that actinide production is especially sensitive to magnetic field strength, with overall actinide mass fraction calculated at 1 Gyr post-merger increasing by more than a factor of six with a tenfold increase in magnetic field strength. This hints at a possible connection to the variability in actinide enhancements exhibited by metal poor, r -process-enhanced stars.

Data Science Professional Profiles (DSPP)

description: This document presents the results of the research and development in the EDISON project to define the Data Science Professional profiles (DSPP) that is important for defining the Data Scientist roles in the organisation and their alignment with the organizational goals and mission. The Data Science Professional profiles definition is done in the context of the whole EDISON Data Science Framework. The proposed DSP profiles are defined as an extension to current ESCO (European Skills, Competences, Qualifications and Occupations) taxonomy and is intended to be proposed for formal inclusion of the new Data Science professions family into the future ESCO taxonomy edition. The proposed DSP profiles when adopted by the community will have multiple uses. First of all. they will help organisations to plan their staffing for data related functions when migrating to agile data driven organizational model. The Human Resource (HR) departments can effectively use DSP profiles for vacancy description construction and candidates assessment. When used together with CF-DS, the DSP profiles can provide a basis for building interactive/web based tool for individual competences benchmarking against selected (or desirable) professional profiles as well as advising practitioners on the (up/re-) skilling path.

Figures 16, 26
Etymology. This is called luculentus in reference to its brilliant, shiny surface.
Description. Known from females only. Fore wing length 4.7–7.1 mm (holotype: 4.7 mm). Antenna with 30 flagellomeres. Mesoscutum with only a few punctures along front margin and sometimes along notauli. Scutellum without punctures, all smooth and shining. Mesopleuron with strong and rather dense punctures, smooth inbetween; below subtegular ridge smooth and with or without punctures. Metapleuron with juxacoxal carina absent or at most a short basal carina. Propodeal areas smooth with strong punctures. Hind coxa smooth and shining between strong punctures. Hind femur length to width ratio 3.0– 3.4 in female (male unknown), ventrally with a large tooth that is longer than width of hind tibia at mid length, and adjacent smaller teeth. Hind tibia 1.65–2.4 (1.65) mm. Second tergite 1.75–2.1 (2.1) × longer than wide at base, smooth and shining. Ovipositor 1.3–1.45 (1.3) × as long as hind tibia.
Colouration. Antenna uniformly brown or black. Face black or dark brown with orange inner eye margins and yellow malar space. Clypeus yellow or light orange. Back of head black or dark brown. Mesosoma including propodeum orange. Hind femur black or very dark brown, with apex yellow. Hind tibia black or dark brown. Fore wing strongly infuscate, smoky-brown. Metasomal tergites orange, from tergite 3 onwards with wide, light apical bands that are often laterally interrupted by dark round mark.
Notes. The two specimens that I included in this species differ by size, but still probably belong to the same biological unit. The species is similar to P. b i c i nc t u s, but beside all the differences in colour pattern, it can be distinguished from the shorter ovipositor.

description: To provide a comprehensive data set for track structure-based simulations of radiation damage in DNA, doubly differential electron-impact ionization cross sections of pyrimidine, a building block of the nucleobases cytosine and thymine, were measured for primary electron energies between 30 eV and 1 keV as a function of emission angle and secondary electron energy. The measurements were performed for secondary electron energies from 4 eV to about half of the primary electron energy and for emission angles between 25° and 135°. Based on the experimental doubly differential ionization cross sections, singly differential and total ionization cross sections of pyrimidine were determined and compared to calculations using the BEB model. In addition to the measurements, a theoretical approach for calculating triply and doubly differential ionization cross section was developed, which is based on the distorted wave Born approximation, a single center expansion of molecular orbitals and an averaging of the T-matrix over different molecular orientations. The calculated doubly differential ionization cross sections of pyrimidine show a qualitatively good agreement with the experimental results.

Sub-Sharvin conductance and incoherent shot-noise in graphene disks at magnetic field

description: Highly-doped graphene samples show the conductance reduced and the shot-noise power enhanced compared to standard ballistic systems in two-dimensional electron gas. These features can be understood within a model assuming incoherent scattering of Dirac electrons between two interfaces separating the sample and the leads. Here we find, by adopting the above-mentioned model for the edge-free (Corbino) geometry and by means of the computer simulation of quantum transport, that another graphene-specific feature should be observable when the current flow through a doped disk is blocked by high magnetic field. In case the conductance drops to zero, the Fano factor approaches the value of $F\approx{}0.56$, with a very weak dependence on the disk radii ratio. The role of finite source-drain voltages and the system behavior upon tuning the electrostatic potential barrier from a rectangular to parabolic shape are also discussed.

Figures 18, 26
Etymology. The holotype male was reared from a lepidopteran host feeding on mango flowers, hence the name.
Description. Association between sexes uncertain; description based on males unless stated otherwise. Fore wing length 3.6–4.3 mm (holotype: 4.25 mm). Antenna with 26–28 (28) flagellomeres. Mesoscutum punctured on the side, strongly coriaceous on median lobe where punctures almost disappearing (less so in female). Scutellum with obvious punctures, smooth in-between. Mesopleuron with strong and rather dense punctures, smooth inbetween; below subtegular ridge smooth and with or without punctures. Metapleuron with juxacoxal carina absent or at most a short basal carina; propodeal areas smooth with strong punctures. Hind coxa coriaceous and matt, with weak punctures. Hind femur length to width ratio 3.1–3.3 (3.3) in male and 4.0– 4.2 in female, ventrally with a medium sized tooth almost as long as width of hind tibia at mid length. Hind tibia 1.25–1.55 mm. Second tergite 2.9–3.3 × longer than wide at base (2.1 in female), covered with longitudinal carinulae. Ovipositor 1.5–1.9 × as long as hind tibia.
Colouration. Antenna basally orange, remainder brown or black. Head black or dark brown. Clypeus dark brown basally with orange apex (head orange in one of the females). Mesosoma including propodeum orange. Hind femur orange to darkened red-brown, with apex yellow. Hind tibia orange-brown with base and apex broadly darkened, or entirely brown. Fore wing somewhat infuscate. Tergites 1 and 2 orange, remaining tergites orange to dark brown.
Notes. The two females on which part of the description is based are only tentatively associated with the male holotype. The females have a punctured mesoscutum with only some weakly coriaceous areas on the middle lobes, while this character is very pronounced in the males. More material is needed to decide whether this just represents a sexual dimorphism.

Beyond Collaborative Filtering: A Relook at Task Formulation in Recommender Systems

Subjects: subject: Information Retrieval (cs.IR)
subject: FOS: Computer and information sciences

description: Recommender Systems (RecSys) have become indispensable in numerous applications, profoundly influencing our everyday experiences. Despite their practical significance, academic research in RecSys often abstracts the formulation of research tasks from real-world contexts, aiming for a clean problem formulation and more generalizable findings. However, it is observed that there is a lack of collective understanding in RecSys academic research. The root of this issue may lie in the simplification of research task definitions, and an overemphasis on modeling the decision outcomes rather than the decision-making process. That is, we often conceptualize RecSys as the task of predicting missing values in a static user-item interaction matrix, rather than predicting a user's decision on the next interaction within a dynamic, changing, and application-specific context. There exists a mismatch between the inputs accessible to a model and the information available to users during their decision-making process, yet the model is tasked to predict users' decisions. While collaborative filtering is effective in learning general preferences from historical records, it is crucial to also consider the dynamic contextual factors in practical settings. Defining research tasks based on application scenarios using domain-specific datasets may lead to more insightful findings. Accordingly, viable solutions and effective evaluations can emerge for different application scenarios.
