description: At least some fast radio bursts (FRBs) are produced by magnetars. Even though mounting observational evidence points towards a magnetospheric origin of FRB emission, the question of the location for FRB generation continues to be debated. One argument suggested against the magnetospheric origin of bright FRBs is that the radio waves associated with an FRB may lose most of their energy before escaping the magnetosphere because the cross-section for $e^\pm$ to scatter large-amplitude EM waves in the presence of a strong magnetic field is much larger than the Thompson cross-section. We have investigated this suggestion and find that FRB radiation traveling through the open field line region of a magnetar's magnetosphere does not suffer much loss due to two previously ignored factors. First, the plasma in the outer magnetosphere ($r \gta 10^9 \ $cm), where the losses are potentially most severe, is likely to be flowing outward at a high Lorentz factor $γ_p \geq 10^3$. Second, the angle between the wave vector and the magnetic field vector, $θ_B$, in the outer magnetosphere is likely of the order of 0.1 radian or smaller due in part to the intense FRB pulse that tilts open magnetic field lines so that they get aligned with the pulse propagation direction. Both these effects reduce the interaction between the FRB pulse and the plasma substantially. We find that a bright FRB with an isotropic luminosity $L_{\rm frb} \gta 10^{42} \ {\rm erg \ s^{-1}}$ can escape the magnetosphere unscathed for a large section of the $γ_p-θ_B$ parameter space, and therefore conclude that the generation of FRBs in magnetar magnetosphere passes this test.

Simulating the evolution of disc galaxies in a group environment. II. The influence of close-encounters between galaxies

description: We study the evolution of disc galaxies in group environments under the effect of both the global tidal field and close-encounters between galaxies, using controlled N-body simulations of isolated mergers. We find that close-range encounters between galaxies are less frequent and less damaging to disc galaxies than originally expected, since they mostly occur when group members have lost a significant fraction of their initial mass to tidal stripping. We also find that group members mostly affect disc galaxies indirectly by modifying their common global tidal field. Different initial orbital parameters of group members introduce a significant "scatter" in the evolution of general properties of disc galaxies around a "median" evolution that is similar to when only the effect of the global tidal field is included. Close-encounters introduce a high variability in the properties of disc galaxies, even slowing their evolution in some cases, and could wash out correlations between galaxy properties and the group total mass. The combined effect of the global tidal field and close-encounters appears to be inefficient at forming/enhancing central stellar bulges. This implies that bulges of S0 galaxies should be mostly composed by young stars, which is consistent with recent observations.

description: Lower extremity artery disease (LEAD) affects millions of elderly patients and is associated with elevated cardiovascular morbidity and mortality. Risk factor modification, including the therapy of dyslipidaemia, is mandatory to reduce cardiovascular event rates and to improve survival rates. However, only a minority achieve the recommended low-density lipoprotein cholesterol (LDL-C) target level < 55 mg/dL, according to the current ESC/EAS guidelines on the treatment of dyslipidaemia. This study elucidated the implementation of the lipid-lowering guideline recommendations of 400 LEAD patients with LDL-C > 100 mg/dL and their adherence to treatment adjustment during follow-up. Despite a sustained statin prescription in 93% of the patients, including 77% with high-intensity statins at follow-up, only 18% achieved the target level. Ezetimibe appeared in 21% and LDL-C goals were reached significantly more often with combination therapy. Recurrent revascularization appeared more often (28%) than coronary artery or cerebrovascular disease progression (14%) and 7% died. Despite the frequent use of high-intensity statins and expandable rates of ezetimibe, the progression of cardiovascular events remained inevitable. Only 18% of the patients had received recommendations on lifestyle modification, including dietary adaptations, which is key for a holistic approach to risk factor control. Thus, efforts for both pharmacological and behavioral strategies are needed to improve clinical outcomes and survival rates.

description: Having two "sibling" Type Ia supernovae (SNe Ia) in the same galaxy offers additional advantages in reducing a variety of systematic errors involved in estimating the Hubble constant, $H_{0}$. NGC 4414 is a nearby galaxy included in the Hubble Space Telescope Key Project to measure its distance using Cepheid variables. It hosts two sibling SNe Ia: SN 2021J and SN 1974G. This provides the opportunity to improve the precision of the previous estimate of $H_{0}$, which was based solely on SN 1974G. Here we present new optical $BVRI$ photometry obtained at the Observatorio de Sierra Nevada and complement it with Swift UVOT $UBV$ data, which cover the first 70 days of emission of SN 2021J. A first look at SN 2021J optical spectra obtained with the Gran Telescopio Canarias (GTC) reveals typical SN type Ia features. The main SN luminosity parameters for the two sibling SNe are obtained by using SNooPy, a light curve fitting code based on templates. Using a hierarchical bayesian approach, we build the Hubble diagram with a sample of 96 SNe Ia obtained from the Combined Pantheon Sample in the redshift range $z = 0.02-0.075$, and calibrate the zero point with the two sibling type-Ia SNe in NGC 4414. We report a value of the Hubble constant $H_{0}$ $= 72.19 \pm 2.32$ (stat.) $\pm 3.42$ (syst.) km s$^{-1}$Mpc$^{-1}$. We expect a reduction of the systematic error after a new analysis of the Cepheids period-luminosity relation using the upcoming Gaia DR4 and additional Cepheids from the HST and JWST.

description: We discuss the theoretical bases that underpin the automation of the computations of tree-level and next-to-leading order cross sections, of their matching to parton shower simulations, and of the merging of matched samples that differ by light-parton multiplicities. We present a computer program, MadGraph5_aMC@NLO, capable of handling all these computations -- parton-level fixed order, shower-matched, merged -- in a unified framework whose defining features are flexibility, high level of parallelisation, and human intervention limited to input physics quantities. We demonstrate the potential of the program by presenting selected phenomenological applications relevant to the LHC and to a 1-TeV $e^+e^-$ collider. While next-to-leading order results are restricted to QCD corrections to SM processes in the first public version, we show that from the user viewpoint no changes have to be expected in the case of corrections due to any given renormalisable Lagrangian, and that the implementation of these are well under way.

description: We extend the study of nuclear dependence of the transverse momentum dependent parton distribution functions and azimuthal asymmetries to semi-inclusive deep inelastic scattering (SIDIS) off polarized nuclear targets. We show that azimuthal asymmetries are suppressed for SIDIS off a polarized nuclear target relative to that off a polarized nucleon due to multiple scattering inside the nucleus. Using the value of transport parameter inside large nuclei extracted from jet quenching analyses in SIDIS off nuclear targets, we also present a numerical estimate of the nuclear suppression of the azimuthal asymmetry that might be useful to guide the future experimental studies of SIDIS off polarized nuclear targets.

description: Die Bedeutung von Mustern und Strukturen für das präalgebraische Lernen wird in der fachdidaktischen Literatur immer wieder betont. Während das Verallgemeinern von Mustern als präalgebraische Tätigkeit international und national breit beforscht ist, besteht eine Lücke in der Beforschung präalgebraischer Lernumgebungen mit dem Fokus auf Strukturen (Kieran, 2018). In unserer Entwicklungsforschungsstudie wird daher eine Lernumgebung für die Klasse 5/6 entwickelt und erforscht, die das Beschreiben von Strukturen als Terme und das Verstehen von durch Terme ausgedrückte Strukturen in den Fokus nimmt (Tondorf & Prediger, 2022). Das Prinzip der Darstellungsvernetzung (Wessel, 2015) ist ein leitendes Designprinzip. Im Beitrag wird ein Einblick darüber gegeben, wie diese sich in den Kleingruppenförderungen realisiert und welche Rolle Gestik neben Verbalprache dabei einnimmt.

description: Dirac cones (DCs) play a pivotal role in various unique phenomena ranging from massless electrons in graphene to robust surface states in topological insulators (TIs). Recent studies have theoretically revealed a full Dirac hierarchy comprising an eightfold bulk DC, a fourfold surface DC, and a twofold hinge DC, associated with a hierarchy of topological phases including first-order to third-order three-dimensional (3D) topological insulators, using the same 3D base lattice. Here, we report the first experimental observation of the Dirac hierarchy in 3D acoustic TIs. Using acoustic measurements, we unambiguously reveal that lifting of multifold DCs in each hierarchy can induce two-dimensional (2D) topological surface states with a fourfold DC in a first-order 3D TI, one-dimensional (1D) topological hinge states with a twofold DC in a second-order 3D TI, and zero-dimensional (0D) topological corner states in a third-order 3D TI. Our work not only expands the fundamental research scope of Dirac physics, but also opens up a new route for multidimensional robust wave manipulation.

description: We show that the exact partition function of U(N) six-dimensional gauge theory with eight supercharges on C^2 x S^2 provides the quantization of the integrable system of hydrodynamic type known as gl(N) periodic Intermediate Long Wave (ILW). We characterize this system as the hydrodynamic limit of elliptic Calogero-Moser integrable system. We compute the Bethe equations from the effective gauged linear sigma model on S^2 with target space the ADHM instanton moduli space, whose mirror computes the Yang-Yang function of gl(N) ILW. The quantum Hamiltonians are given by the local chiral ring observables of the six-dimensional gauge theory. As particular cases, these provide the gl(N) Benjamin-Ono and Korteweg-de Vries quantum Hamiltonians. In the four dimensional limit, we identify the local chiral ring observables with the conserved charges of Heisenberg plus W_N algebrae, thus providing a gauge theoretical proof of AGT correspondence.

description: Polaron defects are ubiquitous in materials and play an important role in many processes involving carrier mobility, charge transfer and surface reactivity. Determining the spatial distribution of small polarons is essential to understand materials properties and functionalities. This requires an exploration of the configurational space, which is computationally demanding when using standard first principles methods, and technically prohibitive for many-polaron systems. Here, we propose a machine-learning (ML) accelerated search that compares the energy stability of different polaron patterns and determines the ground state configuration. The kernel-regression based ML model is trained on databases generated by density functional theory (DFT) calculations on a minimal set of initial polaron patterns, obtained by using either molecular dynamics simulations or a random sampling approach. To establish an efficient mapping between training data and configuration stability we designed simple descriptors that model the interactions among polarons and charged point defects. The proposed DFT+ML protocol is used here to explore millions of polaron configurations for two different systems, oxygen defective rutile TiO$_2$(110) and Nb-doped SrTiO$_3$(001). Our data shows that the ML-aided search correctly individuates the ground-state polaron patterns, proposes polaronic configurations not visited in the training and can be used to efficiently determine the optimal distribution of polarons at any charge concentration.

description: Limited by today's physical devices, quantum circuits are usually noisy and difficult to be designed deeply. The novel computing architecture of distributed quantum computing is expected to reduce the noise and depth of quantum circuits. In this paper, we study the Simon's problem in distributed scenarios and design a distributed quantum algorithm to solve the problem. The algorithm proposed by us has the advantage of exponential acceleration compared with the classical distributed computing, and has the advantage of square acceleration compared with the best distributed quantum algorithm proposed before. In particular, the previous distributed quantum algorithm for Simon's problem can not be extended to the case of more than {\it two computing nodes} (i.e. two subproblems), but our distributed quantum algorithm can be extended to the case of {\it multiple computing nodes} (i.e. multiple subproblems) as well.

description: In this paper, a method to represent every input-output trajectory of a continuous-time linear system in terms of previously collected data is presented. This corresponds to a continuous-time version of the well-known Willems' lemma. The result is obtained by sampling the continuous signals at regular intervals, and constructing Hankel-like structures that closely resemble their discrete-time counterparts. Then, it is shown how to use measured persistently excited data to design a time-varying vector of parameters that allows the generation of arbitrary piecewise differentiable trajectories. A class of input signals that satisfies the conditions for persistence of excitation is also provided.

description: Die zunehmende Digitalisierung der Welt führt zu Veränderungen in verschiedenen gesellschaftlichen Domänen. Neben den Auswirkungen auf soziale Domänen kann auch eine digitale Transformation in der Arbeitswelt von mechanischen oder analogen zu digitalen automatisierten Prozessen konstatiert werden (Kirchner, 2015; BMAS, 2016; Kaiser et al., 2021). Dies zeigt sich u.a. in der Zunahme von Informations- und Kommunikationstechnologien (ICT) in Administration und Service. Des Weiteren wird auch in Produktionsprozessen vermehrt auf digitale Technologien zurückgegriffen (Calvino et al., 2018). Ein Beispiel einer neuen relevanten Technologie der digitalen Arbeitswelt ist die 3D-Druck-Technologie. Gemeinsamkeit der unter diesem Überbegriff vereinten Technologien ist der additive Aufbau eines Objekts (Fastermann, 2014; Junk, 2017), der von formativen oder subtraktiven Produktionsverfahren abgegrenzt werden kann. Eine Folge der digitalen Transformation der Arbeitswelt sind die veränderten Anforderungen an die Kompetenzprofile (zukünftiger) Arbeitnehmer*innen (Grundke et al., 2017; BMAS, 2020). Ein wichtiger Bestandteil des Bildungsauftrages allgemeinbildender Schulen ist es, die Lernenden zu einem erfolgreichen Übergang in die Arbeitswelt zu befähigen. Aufgrund dessen soll der Frage nachgegangen werden, inwiefern der 3D-Druck in schulische Prozesse eingebunden werden kann, um den Lernenden die frühzeitige Auseinandersetzung mit einem wichtigen digitalen Werkzeug der modernen Arbeitswelt zu ermöglichen.

description: Decentralized Online Social Networks (DOSNs) represent a growing trend in the social media landscape, as opposed to the well-known centralized peers, which are often in the spotlight due to privacy concerns and a vision typically focused on monetization through user relationships. By exploiting open-source software, DOSNs allow users to create their own servers, or instances, thus favoring the proliferation of platforms that are independent yet interconnected with each other in a transparent way. Nonetheless, the resulting cooperation model, commonly known as the Fediverse, still represents a world to be fully discovered, since existing studies have mainly focused on a limited number of structural aspects of interest in DOSNs. In this work, we aim to fill a lack of study on user relations and roles in DOSNs, by taking two main actions: understanding the impact of decentralization on how users relate to each other within their membership instance and/or across different instances, and unveiling user roles that can explain two interrelated axes of social behavioral phenomena, namely information consumption and boundary spanning. To this purpose, we build our analysis on user networks from Mastodon, since it represents the most widely used DOSN platform. We believe that the findings drawn from our study on Mastodon users' roles and information flow can pave a way for further development of fascinating research on DOSNs.

description: The increasing size of farms, specialisation and growing scale of production are the primary factors in the improvement of resource utilisation in agriculture. In this context, the aim of this study is to assess and compare the efficiency of resource management in farms differing in land area size and specialising in the production of milk and cattle for slaughter. This assessment was based on data from farms participating in the FADN agricultural accountancy system in 2019. The efficiency of utilised factors of production in the researched farms was evaluated based on indexes of productivity and profitability of land, labour and capital. In dairy farms, the productivity of land was considerably higher and was growing with an increase in their size, whereas in beef cattle type farms it generally deteriorated. Productivity of labour and capital was also much greater and was growing faster in dairy farms. The highest profitability of land was recorded for medium-sized farms of both production types, while the profitability of labour and capital was highest in the largest farms. It needs to be stressed that the income and economic efficiency of farms specialising in the production of cattle for slaughter are determined by financial support within the EU Common Agricultural Policy

description: We extend our previous work on the light-quark connected part, $a_μ^{\rm HVP,lqc}$, of the leading order hadronic-vacuum-polarization (HVP) contribution to the muon anomalous magnetic moment $a_μ$, using staggered fermions, in several directions. We have collected more statistics on ensembles with lattice spacings of $0.06$, $0.09$ and $0.12$ fm, and we added two new ensembles, both with lattice spacing $0.15$ fm, but with different volumes. The increased statistics allow us to reduce statistical errors on $a_μ^{\rm HVP,lqc}$ and related window quantities significantly. We also calculate the current-current correlator from which $a_μ^{\rm HVP,lqc}$ is obtained to next-to-next-to-leading order (NNLO) in staggered chiral perturbation theory, so that we can correct lattice values for $a_μ^{\rm HVP,lqc}$ to NNLO for finite-volume, pion-mass mistuning and taste-breaking effects. We discuss the applicability of NNLO chiral perturbation theory to $a_μ^{\rm HVP,lqc}$ and to the window quantities, emphasizing that it provides a systematic EFT approach to $a_μ^{\rm HVP,lqc}$, but not to short- or intermediate-distance window quantities. This makes it difficult to assess systematic errors on the standard intermediate-distance window quantity that is now widely considered in the literature. In view of this, we investigate a longer-distance window, for which EFT methods should be more reliable. Our most important conclusion is that, especially for staggered fermions, new high-statistics computations at lattice spacings smaller than $0.06$ fm are indispensable.

description: Testlet design is very popular in educational and psychological assessments. This article proposes a new cognitive diagnosis model, the Multiple-Choice Cognitive Diagnostic Testlet (MC-CDT) model for a test with testlets consisting of multiple-choice (MC) items. The MC-CDT model uses the original examinees' responses to MC items instead of dichotomously scored data (i.e. correct or incorrect) to retain the information from different distractors and thus enhance the MC items' diagnostic power. The MCMC algorithm is adopted to calibrate the model implemented in the WinBUGS software. Then, a thorough simulation study is conducted to evaluate the estimation accuracy for both item and examinee parameters in the MC-CDT model under various conditions. The results show that the proposed MC-CDT model outperforms the traditional MC cognitive diagnostic model. Specifically, the MC-CDT model can fit the data with testlets better than the traditional model, while it can still fit the data without testlets well. Finally, an empirical study proves that the MC-CDT model fits the real data better than the traditional model, and it can also provide testlet information.

description: Quantum coherences characterise the ability of particles to quantum mechanically interfere within some given distances. In the context of noisy many-body quantum systems these coherences can fluctuate. A simple toy model to study such fluctuations in an out-of-equilibrium setting is the open quantum symmetric simple exclusion process (Q-SSEP) which describes spinless fermions in one dimension hopping to neighbouring sites with random amplitudes coupled between two reservoirs. Here we show that the dynamics of fluctuations of coherences in Q-SSEP have a natural interpretation as free cumulants, a concept from free probability theory. Based on this insight we provide heuristic arguments why we expect free probability theory to be an appropriate framework to describe coherent fluctuations in generic mesoscopic systems where the noise emerges from a coarse-grained description. In the case of Q-SSEP we show how the link to free probability theory can be used to derive the time evolution of connected fluctuations of coherences as well as a simple steady state solution.

description: In symmetry based approaches to black hole entropy, we calculate the central charge of the Virasoro algebra in the first order formulation of gravity for both Palatini and Holst actions. In these calculations, we made use of the NHEK metric and the Kerr-CFT correspondence. For the Palatini action the results obtained in the second order formulation are reproduced. We also argue that the Holst term does not contribute to the charge algebra no matter what geometry/boundary conditions one is considering.

The MC-CDT model uses the original examinees’ responses to MC items instead of dichotomously scored data (i.e. correct or incorrect) so that it retains the information from different distractors and thus enhances the diagnostic power of MC items.

A thorough simulation study is conducted to evaluate the estimation accuracy for both item and examinee parameters in the MC-CDT model under various conditions. Moreover, a comparison between the proposed model and the traditional MC cognitive diagnostic model is conducted using simulated MC response data with or without testlets. The results show that the proposed MC-CDT model outperforms the traditional MC cognitive diagnostic model. Specifically, the MC-CDT model can fit the data with testlets better than the traditional model while it can still fit the data without testlets well. Subsequently, an empirical study proves that the MC-CDT model fits the real data better than traditional model does, and it can provid testlet information in addition. Future research directions are discussed in the end.

description: A block Markov chain is a Markov chain whose state space can be partitioned into a finite number of clusters such that the transition probabilities only depend on the clusters. Block Markov chains thus serve as a model for Markov chains with communities. This paper establishes limiting laws for the singular value distributions of the empirical transition matrix and empirical frequency matrix associated to a sample path of the block Markov chain whenever the length of the sample path is $Θ(n^2)$ with $n$ the size of the state space. The proof approach is split into two parts. First, we introduce a class of symmetric random matrices with dependent entries called approximately uncorrelated random matrices with variance profile. We establish their limiting eigenvalue distributions by means of the moment method. Second, we develop a coupling argument to show that this general-purpose result applies to the singular value distributions associated with the block Markov chain.

description: Automatischem Feedback in digitalen Lernumgebungen wird das Potential zugesprochen, Lernprozesse positiv zu beeinflussen (Olsher et al., 2016). Häufig werden Lernende jedoch nicht aktiv in den Feedbackprozess einbezogen. Dies kann dazu führen, dass Lernende das Feedback nicht verstehen oder ihm keinen Sinn zuschreiben, sodass sie dieses nicht, oder nicht wie intendiert, für den weiteren Lernprozess nutzen (Leighton, 2019; Rezat, 2021). Im vorliegenden Projekt wird untersucht, wie die Lernenden durch eine Kombination von Selbst-Assessment und automatischem Assessment stärker in den Feedbackprozess eingebunden werden können.

description: The Sunyaev-Zeldovich effect towards clusters of galaxies has become a standard probe of cosmology. It is caused by the scattering of photons from the cosmic microwave background (CMB) by the hot cluster electron gas. In a similar manner, other photon backgrounds can be scattered when passing through the cluster medium. This problem has been recently considered for the radio and the cosmic infrared background. Here we revisit the discussion of the cosmic infrared background (CIB) including several additional effects that were omitted before. We discuss the {\it intracluster} scattering of the CIB and the role of {\it relativistic} temperature corrections to the individual cluster and all-sky averaged signals. We show that the all-sky CIB distortion introduced by the scattering of the photon field was underestimated by a factor of $\simeq 1.5$ due to neglecting the intracluster scattering contribution. Energy is essentially transferred twice from the thermal electrons to the CIB. We carefully clarify the origin of various effects in the calculation of the average CIB and also scattered signals. The single-cluster CIB scattering signal also exhibits a clear redshift dependence, which can be used in cosmological analyses, as we describe both analytically and numerically. This may open a new way for cosmological studies with future CMB experiments.

description: To any positive contraction $Q$ on $\ell^2(W)$, there is associated a determinantal probability measure ${\mathbf P}^Q$ on $2^W$, where $W$ is a denumerable set. Let $Γ$ be a countable sofic finitely generated group and $G = (Γ, \mathsf{E})$ be a Cayley graph of $Γ$. We show that if $Q_1$ and $Q_2$ are two $Γ$-equivariant positive contractions on $\ell^2(Γ)$ or on $\ell^2(\mathsf{E})$ with $Q_1 \le Q_2$, then there exists a $Γ$-invariant monotone coupling of the corresponding determinantal probability measures witnessing the stochastic domination ${\bf P}^{Q_1} \preccurlyeq {\bf P}^{Q_2}$. In particular, this applies to the wired and free uniform spanning forests, which was known before only when $Γ$ is residually amenable. In the case of spanning forests, we also give a second more explicit proof, which has the advantage of showing an explicit way to create the free uniform spanning forest as a limit over a sofic approximation. Another consequence of our main result is to prove that all determinantal probability measures ${\bf P}^Q$ as above are ${\bar d}$-limits of finitely dependent processes. Thus, when $Γ$ is amenable, ${\bf P}^Q$ is isomorphic to a Bernoulli shift, which was known before only when $Γ$ is abelian. We also prove analogous results for sofic unimodular random rooted graphs.
