description: We present deep Hubble Space Telescope near-infrared (NIR) observations of the magnetar SGR 1935+2154 from June 2021, approximately 6 years after the first HST observations, a year after the discovery of fast radio burst like emission from the source, and in a period of exceptional high frequency activity. Although not directly taken during a bursting period the counterpart is a factor of ~1.5 to 2.5 brighter than seen at previous epochs with F140W(AB) = $24.65\pm0.02$ mag. We do not detect significant variations of the NIR counterpart within the course of any one orbit (i.e. on minutes-hour timescales), and contemporaneous X-ray observations show SGR 1935+2154 to be at the quiescent level. With a time baseline of 6 years from the first identification of the counter-part we place stringent limits on the proper motion of the source, with a measured proper motion of $μ = 3.1\pm1.5$ mas/yr. The direction of proper motion indicates an origin of SGR 1935+2154 very close to the geometric centre of SNR G57.2+08, further strengthening their association. At an adopted distance of $6.6\pm0.7$ kpc, the corresponding tangential space velocity is ${ν_T} = 97\pm48$ km/s (corrected for differential Galactic rotation and peculiar Solar motion), although its formal statistical determination may be compromised owing to few epochs of observation. The current velocity estimate places it at the low end of the kick distribution for pulsars, and makes it among the lowest known magnetar kicks. When collating the few-magnetar kick constraints available, we find full consistency between the magnetar kick distribution and the much larger pulsar kick sample

description: The $k$-essence theory is a prototypical class of scalar-field models that already gives rich phenomenology and has been a target of extensive studies in cosmology. General forms of shift-symmetric $k$-essence are known to suffer from formation of caustics in a planar-symmetric configuration, with the only exceptions of canonical and DBI-/cuscuton-type kinetic terms. With this in mind, we seek for multi-field caustic-free completions of a general class of shift-symmetric $k$-essence models in this paper. The field space in UV theories is naturally curved, and we introduce the scale of the curvature as the parameter that controls the mass of the heavy field(s) that would be integrated out in the process of EFT reduction. By numerical methods, we demonstrate that the introduction of a heavy field indeed resolves the caustic problem by invoking its motion near the would-be caustic formation. We further study the cosmological application of the model. By expanding the equations with respect to the curvature scale of the field space, we prove that the EFT reduction is successfully done by taking the limit of infinite curvature, both for the background and perturbation, with gravity included. The next leading-order computation is consistently conducted and shows that the EFT reduction breaks down in the limit of vanishing sound speed of the perturbation.

description: In previous work by Y. Guo and G. Rein, nonlinear stability of equilibria in stellar dynamics, i.e., of steady states of the Vlasov-Poisson system, was accessed by variational techniques. Here we propose a different, non-variational technique and use it to prove nonlinear stability of the King model against a class of spherically symmetric, dynamically accessible perturbations. This model is very important in astrophysics and was out of reach of the previous techniques.

description: Our sample of giant radio-source candidates, published in Paper I (Machalski et al. 2001), is updated and supplemented with further radio and optical data. In this paper we present: (i) newly detected host galaxies, their photometric magnitude, and redshift estimate for the sample sources not identified yet, (ii) optical spectra and spectroscopic redshift for the host galaxies fainter than about 18.5 mag taken with the Apache Point Observatory 3.5m telescope, and (iii) the VLA 4.9 GHz total-intensity and polarised-intensity radio maps of the sample members. In a few cases they reveal extremely faint radio cores undetected before, which confirm the previously uncertain optical identifications. The radio maps are analysed and the polarisation properties of the sample sources summarised. A comparison of our updated sample with three samples published by other authors implies that all these four samples probe the same part of the population of extragalactic radio sources. There is no significant difference between the distributions of intrinsic size and radio power among these samples. The median redshift of 0.38 +/- 0.07 in our sample is the highest among the corresponding values in the four samples, indicating that the angular size and flux-density limits in our sample, lower than those for the other three samples, result in effective detections of more distant, giant-size galaxies compared to those detected in the other samples. This sample and a comparison sample of `normal'-size radio galaxies will be used in Paper III (Machalski & Jamrozy 2006) to investigate of a number of trends and correlations in the entire data.

Observables in leading order sensitive to alpha_S as well as alpha_S**2 are used. The evolution of alpha_S with respect to the centre-of-mass energy as predicted by QCD is studied and confirmed with high precision. All measurements of alpha_S are consistent with the current world average.

description: Non-Hermitian topological phases exhibit a number of exotic features that have no Hermitian counterparts, including the skin effect and breakdown of the conventional bulk-boundary correspondence. Here, we implement the non-Hermitian Su-Schrieffer-Heeger (SSH) Hamiltonian, which is a prototypical model for studying non-Hermitian topological phases, with a solid-state quantum simulator consisting of an electron spin and a $^{13}$C nuclear spin in a nitrogen-vacancy (NV) center in a diamond. By employing a dilation method, we realize the desired non-unitary dynamics for the electron spin and map out its spin texture in the momentum space, from which the corresponding topological invariant can be obtained directly. Our result paves the way for further exploiting and understanding the intriguing properties of non-Hermitian topological phases with solid-state spins or other quantum simulation platforms.

description: The mid-term fractional frequency stability of miniaturized atomic clocks can be limited by light-shift effects. In this Letter, we demonstrate the implementation of a symmetric Auto-Balanced Ramsey (SABR) interrogation sequence in a microcell-based atomic clock based on coherent population trapping (CPT). Using this advanced protocol, the sensitivity of the clock frequency to laser power, microwave power and laser frequency variations is reduced, at least by one order of magnitude, in comparison with continuous-wave (CW) or Ramsey interrogation schemes. Light-shift mitigation obtained with the SABR sequence benefits greatly to the clock Allan deviation for integration times between 10$^2$ and 10$^5$ s. These results demonstrate that such interrogation techniques are of interest to enhance timekeeping performances of chip-scale atomic clocks.
Probing the Gravitational Scale via Running Gauge Couplings

description: According to a recent paper by Robinson and Wilczek, the leading gravitational corrections to the running of gauge couplings tend to reduce the values of the couplings at energies below the gravitational scale, defined to be the energy above which gravity becomes strongly interacting. If the physical gravitational scale is sufficiently low, as conjectured in certain extra-dimension models, this behavior of the gauge couplings can be measured in future high energy experiments, providing a way to determine where the gravitational scale lies. We estimate that measurements of the fine structure constant at the Large Hadron Collider and the proposed International Linear Collider energies can probe the gravitational scale up to several hundred TeV, which will be the most stringent test that can be obtained in the conceivable future.

description: We present a comprehensive first-principles Density Functional Theory (DFT) analyses of the interfacial strength and bonding mechanisms between crystalline and amorphous selenium(Se) with graphene(Gr), a promising duo for energy storage applications. Comparative interface analyses are presented on amorphous silicon(Si) with graphene and crystalline Se with aluminum(Al) substrate. The interface strength of monoclinic Se (0.43 J/m2) and amorphous Si with graphene (0.41 J/m2) is similar in magnitude. While both materials (c-Se, a-Si) are bonded loosely by van der Waals (vdW) forces over graphene, interfacial electron exchange is higher for a-Si/Gr. This is further elaborated by comparing potential energy step and charge transfer (delta q) across the graphene interfaces. The delta q for c-Se/Gr and a-Si/Gr are 0.3119 e-1 and 0.4266 e-1, respectively. However, the interface strength of c-Se on the 3D Al substrate is higher (0.99 J/m2), suggesting stronger adhesion. The amorphous Se with graphene has comparable interface strength (0.34 J/m2), but electron exchange in this system is slightly distinct from monoclinic Se. The electronic characteristics (density of states analysis) and bonding mechanisms are different for monoclinic and amorphous Se with graphene and they activate graphene via surface charge doping divergently. Our findings highlight the complex electrochemical phenomena in Se interfaced with graphene, which may profoundly differ from their 'free' counterparts.

description: Improved staggered fermion formulations are a popular choice for lattice QCD calculations. Historically, the algorithm used for such calculations has been the inexact R algorithm, which has systematic errors that only vanish as the square of the integration step-size. We describe how the exact Rational Hybrid Monte Carlo (RHMC) algorithm may be used in this context, and show that for parameters corresponding to current state-of-the-art computations it leads to a factor of approximately seven decrease in cost as well as having no step-size errors.

Pleasure in complicity : a motel, banquet rooms, and retail space in Richmond
Creators: name: Jacobson, Michael William
Publisher: name: University of British Columbia
Year: 2009

description: Ideas of typology are pursued, expanding on popular preconceptions of automobile culture and strip architecture. The elements of type are investigated through an analysis of their physical, social, and economic relationships. An argument of complicity is developed as an alternative to the traditional "eurourbanism" common to many municipal design guidelines. This position seeks to work within the context of the existing city, taking pleasure in its margins, gaps, and adjacencies. Considering the particular physical, cultural and economic conditions of the City of Richmond, this project is framed as the identification of an emerging spatial conception and program/use. The physical space of the city is seen to be shaped most directly by the inclusion of the automobile. The cultural influences of immigration are read on the surfaces of the city and through building programme. Economic realities shape the space of the city as a commodity to be constructed, marketed, and consumed. Through the analysis of the site and contextual conditions, strategies of spatial investigation emerged: the folding of the plane of the city (street) into the space of the building, the horizontal framing of the space of the city (serving as reference and dis-locator to both the automobile and the body as these move through the spaces of the project), and the assemblage of existing types to produce hybrid/mutant types.

description: Several observational and theoretical studies suggest that the initial mass function (IMF) slope for massive stars in globular clusters (GCs) depends on the initial cloud density and metallicity, such that the IMF becomes increasingly top-heavy with decreasing metallicity and increasing the gas density of the forming object. Using N-body simulations of GCs starting with a top-heavy IMF and undergo early gas expulsion within a Milky Way-like potential, we show how such a cluster would evolve. By varying the degree of top-heaviness, we calculate the dissolution time and the minimum cluster mass needed for the cluster to survive after 12 Gyr of evolution.

description: We calculate the P-shell--to-S-shell decay lifetime τ(P->S) of electrons in lens-shaped self-assembled (In,Ga)As/GaAs dots due to Auger electron-hole scattering within an atomistic pseudopotential-based approach. We find that this relaxation mechanism leads to fast decay of τ(P->S)~1-7 ps for dots of different sizes. Our calculated Auger-type P-shell--to-S-shell decay lifetimes τ(P->S) compare well to data in (In,Ga)As/GaAs dots, showing that as long as holes are present there is no need for an alternative polaron mechanism.

description: Random utility theory is founded on the concept that an individual selects the alternative that gives them the highest level of utility, given the individual’s preferences and perception of a good. Discrete choice analysis, however, seldom uses an individual’s perception of a good, instead, more convenient objective data are employed. This paper aims to explore the viability of objective data as a suitable replacement for subjective data in recreational site choice modelling. Random parameter logits are applied to coarse angling site choice data where two site attribute data sets are used; the first is comprised of users’ perception of the site attributes and the second is composed of fishery managers’ perspective of those same attributes. The results reveal that models based on the subjective data outperform those of the objective data. The derived welfare estimates indicate a divergence between the two sources of data in terms of the magnitude of the estimates but not direction. Further analysis is conducted to determine if the manager’s objective ratings are measuring the sites using a similar set of criteria as the user’s subjective ratings. The results suggest that the managers’ perspective is closely aligned with the anglers’ who frequent the sites most often.

description: In recent years, many explanation methods have been proposed to explain individual classifications of deep neural networks. However, how to leverage the created explanations to improve the learning process has been less explored. As the privileged information, the explanations of a model can be used to guide the learning process of the model itself. In the community, another intensively investigated privileged information used to guide the training of a model is the knowledge from a powerful teacher model. The goal of this work is to leverage the self-explanation to improve the learning process by borrowing ideas from knowledge distillation. We start by investigating the effective components of the knowledge transferred from the teacher network to the student network. Our investigation reveals that both the responses in non-ground-truth classes and class-similarity information in teacher's outputs contribute to the success of the knowledge distillation. Motivated by the conclusion, we propose an implementation of introspective learning by distilling knowledge from online self-explanations. The models trained with the introspective learning procedure outperform the ones trained with the standard learning procedure, as well as the ones trained with different regularization methods. When compared to the models learned from peer networks or teacher networks, our models also show competitive performance and requires neither peers nor teachers.

description: We describe the evolution of the early and late universe from thermodynamic considerations, using the generalized non-extensive Tsallis entropy with a variable exponent. A new element in our analysis is the inclusion of a bulk viscosity in the description of the cosmic fluid. Using the generalized Friedmann equation, a description of the early and the late universe is obtained.

description: A review of our works providing a theoretical description of incoherent pion photoproduction on the deuteron is presented. The existing $γd\toπNN$ data are analysed, especially those obtained more recently by the CLAS Collaboration at JLab, the A2 Collaboration at MAMI at Mainz, and the PION@MAX-lab Collaboration at Lund. A procedure, which accounts for the final state interactions (FSI), is applied to extract $γn\toπN$ differential cross sections from the deuteron data. The role of FSI is discussed. We also comment on the results of other works in connection with some discrepancies seen in comparing the model with experiment. The electromagnetic properties of baryon $N^\ast$ resonances, improved using the extracted $γn\toπN$ differential cross sections, are presented. A model description of the cross section data from charged-pion photoproduction reactions $γd\toπ^{\pm}NN$ near threshold is also given. The $γd\toπ^-pp$ data are used to extract the $E_{0+}$ multipole and total crsoss sections of the reaction $γn\toπ^-p$ near threshold.

description: The field of reinforcement learning has made significant progress in recent years, with deep reinforcement learning (RL) being a major contributor. However, there are still challenges associated with the effective training of RL algorithms, particularly with respect to sample efficiency and generalization. This thesis aims to address these challenges by developing RL algorithms capable of generalizing to unseen environments and adapting to dynamic conditions, thereby expanding the practical applicability of RL in real-world tasks. The first contribution of this thesis is the development of novel policy optimization techniques that enhance the generalization capabilities of RL agents. These techniques include the Thinker method, which employs style transfer to diversify observation trajectories, and Bootstrap Advantage Estimation, which improves policy and value function learning through augmented data. These methods have demonstrated superior performance in standard benchmarks, outperforming existing data augmentation and policy optimization techniques. Additionally, this thesis introduces Robust Policy Optimization, a method that enhances exploration in policy gradient-based RL by perturbing action distributions. This method addresses the limitations of traditional methods, such as entropy collapse and primacy bias, resulting in improved sample efficiency and adaptability in continuous action spaces. The thesis further explores the potential of natural language descriptions as an alternative to image-based state representations in RL. This approach enhances interpretability and generalization in tasks involving complex visual observations by leveraging large language models. Furthermore, this work contributes to the field of semi-autonomous teleoperated robotic surgery by developing systems capable of performing complex surgical tasks remotely, even under challenging conditions such as communication delays and data scarcity. The creation of the DESK dataset supports knowledge transfer across different robotic platforms, further enhancing the capabilities of these systems. Overall, the advancements presented in this thesis represent significant steps toward developing more robust, adaptable, and efficient autonomous agents. These contributions have broad implications for various real-world applications, including autonomous systems, robotics, and safety-critical tasks such as medical surgery.

description: The program HiggsSignals confronts the predictions of models with arbitrary Higgs sectors with the available Higgs signal rate and mass measurements, resulting in a likelihood estimate. A new version of the program, HiggsSignals-2, is presented that contains various improvements in its functionality and applicability. In particular, the new features comprise improvements in the theoretical input framework and the handling of possible complexities of beyond-the-SM Higgs sectors, as well as the incorporation of experimental results in the form of Simplified Template Cross Section (STXS) measurements. The new functionalities are explained, and a thorough discussion of the possible statistical interpretations of the HiggsSignals results is provided. The performance of HiggsSignals is illustrated for some example analyses. In this context the importance of public information on certain experimental details like efficiencies and uncertainty correlations is pointed out. HiggsSignals is continuously updated to the latest experimental results and can be obtained at https://www.gitlab.com/higgsbounds/higgssignals .

description: „Türkisch braucht sie nicht und Kurdisch sowieso nicht!“ „Von Deutsch ist er ständig umgeben, er kann es ja gar nicht verlernen!“ „Man sollte Kindern verbieten, in der Erstsprache zu sprechen!“ So unterschiedlich können Ansichten, Haltungen und Einstellungen von Eltern und rechtlichen Erziehungsberechtigten gegenüber Sprachen (Erstsprachen, Zweitsprache, Migrationssprachen und Minderheitensprachen sowie prestigereichen Sprachen) sein. Die vorliegende Masterarbeit fokussiert Spracheinstellungen und Haltungen von Eltern und Erziehungsberechtigten, die in der zweiten Generation in Österreich leben und meist Kontakt zu mehreren Sprachen haben, bzw. von ihnen umgeben aufwachsen. Mithilfe des postmigrantischen Paradigmenwechsels und dem problemzentrierten Interview als Erhebungsmethode enthüllt die Studie die komplexen Zusammenhänge zwischen den individuellen Sprachbiographien, dem Sprachprestige innerhalb der Gesellschaft, den Spracheinstellungen und der familiären Sprachorganisation. Die Erkenntnisse verweisen auf die Vielfalt an Herausforderungen, denen Eltern und Erziehungsberechtigte aus Familien mit Einwanderungsgeschichte begegnen, ihre Ängste und Sorgen hinsichtlich der (sprachlichen) Bildung ihrer Kinder, ihren Wunsch gehört zu werden sowie auf die Notwendigkeit, stereotype Zuschreibungen zu überwinden und sie stärker als Kooperationspartner:innen in Bildungsprozesse einzubinden.
description: "She doesn't need Turkish and certainly not Kurdish!" „He is surrounded by German all the time, he can't unlearn it! „Children should be forbidden to speak in their first language!“ The views, attitudes and behaviours of parents and legal guardians towards languages (first languages, second languages, migrant languages and minority languages and also prestigious languages) can be different like these. This master thesis focusses on language attitudes and behaviours of parents and legal guardians who live in the second generation in Austria and usually have contact with several languages or grow up surrounded by them. By using a shift to the postmigrational paradigm and the problemcentred interviews as data collection method, the study reveals the complex interrelations between individual language biographies, language prestige in society, language attitudes and the family language organization. The findings point to the diversity of challenges faced by parents and legal guardians from families with a migration history, their fears and concerns regarding the (language-related) education of their children, their desire to be heard, and in this sense, as well as the need to overcome stereotypical attributions and to involve them more as cooperation partners in educational processes.

description: In a theory with linear confinement, such as QCD, the masses squared m^2 of mesons with high spin S or high radial excitation number n are expected, from semiclassical arguments, to grow linearly with S and n. We show that this behavior can be reproduced within a putative 5-dimensional theory holographically dual to QCD (AdS/QCD). With the assumption that such a dual theory exists and describes highly excited mesons as well, we show that asymptotically linear m^2 spectrum translates into a strong constraint on the INFRARED behavior of that theory. In the simplest model which obeys such a constraint we find m^2 ~ (n+S).

Common envelope jets supernova r-process yields can reproduce $\rm [Eu/Fe]$ abundance evolution in the Galaxy

description: We use a numerical Galactic chemical evolution model and find that the common envelope jets supernova (CEJSN) r-process scenario can account for both the very early average ratio of europium to iron and its evolution at later times in the Milky-Way (MW) Galaxy. In the CEJSN scenario a neutron star (NS) spirals-in inside a red supergiant (RSG) star all the way to the core and destroys it. According to this scenario r-process isotopes are nucleosynthesized inside neutron-rich jets that the accretion disk around the NS launches inside the core. The merger of a NS with an RSG core already takes place in the very young Galaxy. We conclude that CEJSNe can be a major contributor to r-process nucleosynthesis.

Power-like corrections and the determination of the gluon distribution

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Power-suppressed corrections to parton evolution may affect the theoretical accuracy of current determinations of parton distributions. We study the role of multigluon-exchange terms in the extraction of the gluon distribution for the Large Hadron Collider (LHC). Working in the high-energy approximation, we analyze multi-gluon contributions in powers of 1/Q^2. We find a moderate, negative correction to the structure function's derivative d F_2 / d \ln Q^2, characterized by a slow fall-off in the region of low to medium Q^2 relevant for determinations of the gluon at small momentum fractions.
