description: This paper deals with the issue of the accession of the European Union to the Council of Europe Convention on Preventing and Combating Violence against Women and Domestic Violence (so-called Istanbul Convention). The main point of reflection is the recent Opinion 1/19 of the European Court of Justice. The European Union has already approved legal tools that to some extent can guarantee the protection of women victims of violence. However, the conclusion of the Istanbul Convention will allow the EU to confirm its commitment to combat violence against women in its territory and globally, and to strengthen the current political action and the existing legal framework in the area of criminal procedural law.

description: We analyze the spatial dynamics of polarized atom vapor and present a mathematical method to eliminate the diffusion effect partially. It is found that the diffusion effect of polarized atoms can be regarded as a low pass filter in spatial frequency domain and fits well with a Butterworth filter. The fitted spatial filter can be used to restore the original magnetic image before being blurred by the diffusion, thus improving the magnetic spatial resolution. The results of spatial dynamics simulation and magnetic image restoration show the potential usage of this method in magnetic gradiometer and atomic magnetic microscopy.

A kinetic model of atomic ordering in metal-doped graphene with stoichiometric (1/8, 1/4, 1/2) and nonstoichiometric compositions is developed. Inasmuch as the intrasublattice and intersublattice 'interchange' ('mixing') energies are competitively different for graphene-based lattice, kinetic curves of the long-range order (LRO) parameters may be nonmonotonic for the structures described by two or three LRO parameters.

description: We discuss control of the quantum-transport properties of a mesoscopic device by connecting it in a coherent feedback loop with a quantum-mechanical controller. We work in a scattering approach and derive results for the combined scattering matrix of the device-controller system and determine the conditions under which the controller can exert ideal control on the output characteristics. As concrete example we consider the use of feedback to optimise the conductance of a chaotic quantum dot and investigate effects of controller dimension and decoherence. In both respects we find that the performance of the feedback geometry is well in excess of that offered by a simple series configuration.

description: Mechanisms of aerial righting in juvenile Chukar Partridge (Alectoris chukar) were studied from hatching through 14 days post hatching (dph). Asymmetric movements of the wings were used from 1 to 8 dph to effect progressively more successful righting behaviour via body roll. Following 8 dph, wing motions transitioned to bilaterally symmetric flapping that yielded aerial righting via nose down pitch, along with substantial increases in vertical force production during descent. Ontogenetically, the use of such wing motions to effect aerial righting precedes both symmetric flapping and a previously documented behaviour in chukar (i.e., wing assisted incline running) hypothesized to be relevant to incipient flight evolution in birds. These findings highlight the importance of asymmetric wing activation and controlled aerial manoeuvres during bird development, and are potentially relevant to understanding the origins of avian flight.

Background
The British Social Attitudes (BSA) survey series began in 1983. The series is designed to produce annual measures of attitudinal movements to complement large-scale government surveys that deal largely with facts and behaviour patterns, and the data on party political attitudes produced by opinion polls. One of the BSA's main purposes is to allow the monitoring of patterns of continuity and change, and the examination of the relative rates at which attitudes, in respect of a range of social issues, change over time. Some questions are asked regularly, others less often. Funding for BSA comes from a number of sources (including government departments, the Economic and Social Research Council and other research foundations), but the final responsibility for the coverage and wording of the annual questionnaires rests with NatCen Social Research (formerly Social and Community Planning Research). The BSA has been conducted every year since 1983, except in 1988 and 1992 when core funding was devoted to the British Election Study (BES).

description: We calculate exactly the QNF of the vector type and scalar type electromagnetic fields propagating on a family of five-dimensional topological black holes. To get a discrete spectrum of quasinormal frequencies for the scalar type electromagnetic field we find that it is necessary to change the boundary condition usually imposed at the asymptotic region. Furthermore for the vector type electromagnetic field we impose the usual boundary condition at the asymptotic region and we discuss the existence of unstable quasinormal modes in the five-dimensional topological black holes.

description: New high variability extragalactic sources may be identified by comparing the flux of sources seen in the XMM-Newton Slew Survey with detections and upper limits from the ROSAT All Sky Survey. In November 2012, X-ray emission was detected from the galaxy XMMSL1 J061927.1-655311 (a.k.a. 2MASX 06192755-6553079), a factor 140 times higher than an upper limit from 20 years earlier. Both the X-ray and UV flux subsequently fell, over the following year, by factors of 20 and 4 respectively. Optically, the galaxy appears to be a Seyfert I with broad Balmer lines and weak, narrow, low-ionisation emission lines, at a redshift of 0.0729. The X-ray luminosity peaks at Lx ~ 8x10^43 ergs/s with a typical Sy I-like power-law X-ray spectrum of index ~ 2. The flare has either been caused by a tidal disruption event or by an increase in the accretion rate of a persistent AGN.

Non-Axisymmetric Flows on Hot Jupiters with Oblique Magnetic Fields

description: Giant planets that reside in close proximity to their host stars are subject to extreme irradiation, which gives rise to thermal ionization of trace Alkali metals in their atmospheres. On objects where the atmospheric electrical conductivity is substantial, the global circulation couples to the background magnetic field, inducing supplementary fields and altering the nature of the flow. To date, a number of authors have considered the influence of a spin-pole aligned dipole magnetic field on the dynamical state of a weakly-ionized atmosphere and found that magnetic breaking may lead to significantly slower winds than predicted within a purely hydrodynamical framework. Here, we consider the effect of a tilted dipole magnetic field on the circulation and demonstrate that in addition to regulating wind velocities, an oblique field generates stationary non-axisymmetric structures that adhere to the geometry of the magnetic pole. Using a kinematic perturbative approach, we derive a closed-form solution for the perturbed circulation and show that the fractional distortion of zonal jets scales as the product of the field obliquity and the Elsasser number. The results obtained herein suggest that on planets with oblique magnetic fields, advective shifts of dayside hotspots may have substantial latitudinal components. This prediction may be tested observationally using the eclipse mapping technique.

description: Cytoarchitectonic parcellations of the human brain serve as anatomical references in multimodal atlas frameworks. They are based on analysis of cell-body stained histological sections and the identification of borders between brain areas. The de-facto standard involves a semi-automatic, reproducible border detection, but does not scale with high-throughput imaging in large series of sections at microscopical resolution. Automatic parcellation, however, is extremely challenging due to high variation in the data, and the need for a large field of view at microscopic resolution. The performance of a recently proposed Convolutional Neural Network model that addresses this problem especially suffers from the naturally limited amount of expert annotations for training. To circumvent this limitation, we propose to pre-train neural networks on a self-supervised auxiliary task, predicting the 3D distance between two patches sampled from the same brain. Compared to a random initialization, fine-tuning from these networks results in significantly better segmentations. We show that the self-supervised model has implicitly learned to distinguish several cortical brain areas -- a strong indicator that the proposed auxiliary task is appropriate for cytoarchitectonic mapping.

description: Das zentrale Anliegen dieser Arbeit ist die Selbstwirksamkeitsförderung im Technischen Gestalten bei Jugendlichen mit Lern – und Verhaltensschwierigkeiten. Ausgehend von der Theorie zur Selbstwirksamkeit wurden Mittel gesucht, wie die Quellen der Selbstwirksamkeit und deren kognitive Verarbeitung im schulischen Kontext gestärkt werden können. Im Rahmen einer Aktionsforschung wurde ein Kategoriensystem zur Selbstwirksamkeitsförderung entwickelt und zusammen mit einer didaktisch-methodischen Konzeption in der Praxis erprobt. Drei Oberstufen-Halbklassen einer Sonderschule wurden im Technischen Gestalten in Bezug auf Selbstwirksamkeit gefördert und evaluiert. Die quantitative, wie auch die qualitative Auswertung, zeigen über den Zeitraum der zweimonatigen Forschungsperiode Tendenzen einer kontinuierlichen Verbesserung der Selbstwirksamkeitsförderung und Selbstwirksamkeitserwartung. Sie lassen einen Zusammenhang von Selbstwirksamkeitsförderung und Selbstwirksamkeitserwartung als wahrscheinlich erscheinen.

description: As with any other scholarship, public history has its academic journals. The two main journals are The Public Historian (USA, 1978-) and The Public History Review (Australia, 1992-). As a new-comer in the field, International Public History – the journal of the International Federation for Public History (IFPH) – symbolizes the wish to move away from a predominantly Anglo-Saxon and English-speaking public history. The creation of Public History Weekly (PHW) in 2013 was another early and significant step in this process of internationalization. PHW has published (by March 2018) 260 articles from 74 authors and 479 comments – in 13 languages. All articles – published every Thursday morning – and comments are open access. Open peer-reviewed (OPR), PHW belongs to a new format of publishing in the digital age. In September 2017, Seth Denbo was wondering “Can history accommodate modes of review and publication that would provide greater flexibility and enable nontraditional research outputs to flourish?” With 27,600 visits and 400,000 page-views per month, PHW provides some preliminary answers on what digital and international public history publishing can be.
Hypercritical Accretion, Induced Gravitational Collapse, and Binary-Driven Hypernovae

description: The induced gravitational collapse (IGC) paradigm has been successfully applied to the explanation of the concomitance of gamma-ray bursts (GRBs) with supernovae (SNe) Ic. The progenitor is a tight binary system composed by a carbon-oxygen (CO) core and a neutron star (NS) companion. The explosion of the SN leads to hypercritical accretion onto the NS companion which reaches the critical mass, hence inducing its gravitational collapse to a black hole (BH) with consequent emission of the GRB. The first estimates of this process were based on a simplified model of the binary parameters and the Bondi-Hoyle-Lyttleton accretion rate. We present here the first full numerical simulations of the IGC phenomenon. We simulate the core-collapse and SN explosion of CO stars to obtain the density and ejection velocity of the SN ejecta. We follow the hydrodynamic evolution of the accreting material falling into the Bondi-Hoyle surface of the NS all the way up to its incorporation to the NS surface. The simulations go up to BH formation when the NS reaches the critical mass. For appropriate binary parameters the IGC occurs in short timescales (100-1000s) owing to the combined effective action of the photon trapping and the neutrino cooling near the NS surface. We also show that the IGC scenario leads to a natural explanation for why GRBs are associated only to SN Ic with totally absent or very little helium.

description: High resolution X-ray spectroscopy is a powerful tool for studying the nature of the matter surrounding the neutron star in X-ray binaries and its interaction between the stellar wind and the compact object. In particular, absorption features in their spectra could reveal the presence of atmospheres of the neutron star or their magnetic field strength. Here we present an investigation of the absorption feature at 2.1 keV in the X-ray spectrum of the high mass X-ray binary 4U 1538-52 based on our previous analysis of the XMM-Newton data. We study various possible origins and discuss the different physical scenarios in order to explain this feature. A likely interpretation is that the feature is associated with atomic transitions in an O/Ne neutron star atmosphere or of hydrogen and helium like Fe or Si ions formed in the stellar wind of the donor.

description: \begin{abstract} Using the Keeton and Petters approach, we determine the deflection angle. We also investigate the motion of photons around a parameterized black hole in the presence of non-magnetized cold plasma by using a new ray-tracing algorithm. In spherically symmetric spacetime, we examine the influence of the plasma by applying the Hamiltonian equation on the deflection angle as well as shadow. It is examine to derive the rays analytically from Hamilton's equation by separating the metric and the plasma frequency. We study that the presence of plasma affects the deflection angle as well as shadow for the parameterized black hole and they depend on plasma frequency. If the plasma frequency is significantly lower than the photon frequency, the photon sphere and shadow radius expressions can be linearized around the values found for space light rays. Furthermore, we have graphically analyze the behavior of shadow for distinct positions under the effects of plasma frequency as well as low density plasma medium.

description: We study a quantum system of $p$ commuting matrices and find that such a quantum system requires an explicit curvature dependent potential in its Lagrangian for the system to have a finite energy ground state. In contrast it is possible to avoid such curvature dependence in the Hamiltonian. We study the eigenvalue distribution for such systems in the large matrix size limit. A critical rôle is played by $p=4$. For $p\ge4$ the competition between eigenvalue repulsion and the attractive potential forces the eigenvalues to form a sharp spherical shell.

description: A review of our results on the asymptotic structure of gravity at spatial infinity in four spacetime dimensions is given. Finiteness of the action and integrability of the asymptotic Lorentz boost generators are key criteria that we implement through appropriate boundary conditions. These conditions are `twisted parity conditions', expressing that the leading order of the asymptotic fields obey strict parity conditions under the sphere antipodal map up to an improper gauge transformation. The asymptotic symmetries are shown to form the infinite-dimensional BMS group, which has a non trivial action. The charges and their algebra are worked out. The presentation aims at being self-contained and at possessing a pedagogical component.

On iterated powers of positive definite functions

description: We prove that if $ρ$ is an adapted positive definite function in the Fourier--Stieltjes algebra $B(G)$ of a locally compact group $G$ with $\|ρ\|_{B(G)}=1$, then the iterated powers $(ρ^n)$ converge to zero in the weak* topology $σ(B(G) , C^*(G))$. Moreover, if $ρ$ is irreducible, we prove that $(ρ^n)$ as a sequence of u.c.p. maps on the group $C^*$-algebra converges to zero in the strong operator topology.

description: Nonlinear state-space models are powerful tools to describe dynamical structures in complex time series. In a streaming setting where data are processed one sample at a time, simultaneous inference of the state and its nonlinear dynamics has posed significant challenges in practice. We develop a novel online learning framework, leveraging variational inference and sequential Monte Carlo, which enables flexible and accurate Bayesian joint filtering. Our method provides an approximation of the filtering posterior which can be made arbitrarily close to the true filtering distribution for a wide class of dynamics models and observation models. Specifically, the proposed framework can efficiently approximate a posterior over the dynamics using sparse Gaussian processes, allowing for an interpretable model of the latent dynamics. Constant time complexity per sample makes our approach amenable to online learning scenarios and suitable for real-time applications.

description: Spherical embryos of the algal genus $Volvox$ must turn themselves inside out to complete their embryogenesis. This `inversion', which shares important features with morphological events such as gastrulation in animals, is perhaps the simplest example of a topological transition in developmental biology. Waves of cell shape changes are believed to play a major role in the process, but quantification of the dynamics and formulation of a mathematical description of the process have been lacking. Here, we use selective plane illumination microscopy on $V. globator$ to obtain the first quantitative three-dimensional visualizations of inversion $in~vivo$. A theory is formulated for inversion based on local variations of intrinsic curvature and stretching of an elastic shell, and for the mechanics of an elastic snap-through resisted by the surrounding fluid.

Do audit firms and audit committees enhance earnings quality?

description: This study examines whether audit firms and audit committees contribute to enhancing earnings quality in publicly listed companies. It investigates how the index of audit firms (derived from size, opinion, independence, tenure, quality, and rotation) and audit committees (derived from independence, financial expertise, size, meetings, and gender) impact the accuracy and reliability of reported earnings. An empirical approach is employed using a sample of publicly listed companies over five years. The study utilizes a quantitative methodology, conducting regression analyses to evaluate the relationship between audit firm quality, audit committee characteristics, and earnings quality, as measured by accruals-based metrics and earnings restatements. The results suggest that higher-quality audit firms, particularly the Big 4, and more independent and financially expert audit committees are associated with improved earnings quality. The findings show that these factors reduce earnings manipulation, enhance transparency, and foster higher levels of financial reporting reliability. The study is limited by its focus on publicly listed companies, which may not generalize to private firms or those in non-regulated markets. Additionally, the study is restricted to a specific geographical region, limiting cross-country comparisons. For practitioners, the results highlight the importance of choosing reputable audit firms and ensuring audit committees are composed of independent, financially knowledgeable members to enhance financial reporting quality. The research contributes to greater trust in financial markets by demonstrating that robust governance mechanisms, such as high-quality audits and audit committees, play a vital role in protecting investors' interests and promoting corporate transparency. The study provides evidence that supports strengthening regulatory policies concerning audit firm qualifications and the composition of audit committees to improve corporate governance and protect shareholders. This paper adds value to the existing literature by providing empirical evidence on the combined effect of audit firms and audit committees on earnings quality, offering insights into their complementary roles in enhancing the integrity of financial reporting.

description: We present ALMA continuum and spectral line data at 0.89 mm and 3.2 mm for three disks surrounding young brown dwarfs and very low mass stars in the Taurus star forming region. Dust thermal emission is detected and spatially resolved for all the three disks, while CO(J=3-2) emission is seen in two disks. We analyze the continuum visibilities and constrain the disks physical structure in dust. The results of our analysis show that the disks are relatively large, the smallest one with an outer radius of about 70 AU. The inferred disk radii, radial profiles of the dust surface density and disk to central object mass ratios lie within the ranges found for disks around more massive young stars. We derive from our observations the wavelength dependence of the millimeter dust opacity. In all the three disks data are consistent with the presence of grains with at least millimeter sizes, as also found for disks around young stars, and confirm that the early stages of the solid growth toward planetesimals occur also around very low mass objects. We discuss the implications of our findings on models of solids evolution in protoplanetary disks, on the main mechanisms proposed for the formation of brown dwarfs and very low mass stars, as well as on the potential of finding rocky and giant planets around very low mass objects.
