description: Increasingly, a huge amount of statistics have been gathered which clearly indicates that income and wealth distributions in various countries or societies follow a robust pattern, close to the Gibbs distribution of energy in an ideal gas in equilibrium. However, it also deviates in the low income and more significantly for the high income ranges. Application of physics models provides illuminating ideas and understanding, complementing the observations.

description: The aim of the CASE 2021 Shared Task 1 (Hürriyetoğlu et al., 2021) was to detect and classify socio-political and crisis event information at document, sentence, cross-sentence, and token levels in a multilingual setting, with each of these subtasks being evaluated separately in each test language. Our submission contained entries in all of the subtasks, and the scores obtained validated our research finding: That the multilingual aspect of the tasks should be embraced, so that modeling and training regimes use the multilingual nature of the tasks to their mutual benefit, rather than trying to tackle the different languages separately.

description: The running of the coupling is studied in SU(4) gauge theory using the Schrödinger functional technique. Up to energies of the order of the square root of the string tension $σ$, the running is found to agree with the two-loop perturbative formula. Relating the perturbative to the non-perturbative regime of the running and converting to the $\msbar$ scheme allows one to extract the ratio $Λ_{\msbar}/\sqrtσ$. The result is then used in combination with similar calculations present in the literature for SU(2) and SU(3) to extract $Λ_{\msbar}/\sqrtσ$ in the large $N$ limit. Our results for $N=3,4$ agree with a recent study of the same quantity performed using the Parisi mean field scheme as an intermediate scheme, while $Λ_{\msbar}/\sqrtσ$ in SU(2) turns out to differ by 2.5%. Possible explanations of this discrepancy are discussed.

description: El principal objetivo del estudio fue examinar perfiles de padres respecto a la presión/implicación y apoyo a las necesidades psicológicas básicas (NPB) sobre la motivación y aburrimiento desarrollado por jóvenes deportistas. La muestra estuvo formada por 301 padres y sus respectivos 301 hijos  (M = 13.92; DT = 2.04), quiénes pertenecían a deportes colectivos (n = 191) e individuales (n = 128). Se midieron en padres la percepción de implicación y presión, al igual que el apoyo a las NPB, mientras que la motivación autodeterminada y el aburrimiento en la práctica fueron variables valoradas en adolescentes. Los resultados muestran la existencia de dos perfiles (perfil adaptativo, que estaba compuesto por el apoyo a las NPB y bajos niveles de presión, y perfil desadaptativo, que estaba formado por altos niveles de presión y bajos valores de apoyo a las NPB), y una relación entre el perfil desataptativo de los padres y la motivación de los niños y su aburrimiento en la práctica. Asimismo, se demostró que los padres con un perfil adaptativo realizaban menos actividad física durante la semana. Para concluir, se destaca la importancia de que los padres generen bajos niveles de presión y alta implicación en la práctica deportiva de sus hijos, así como promover el apoyo a las NPB, así como incrementar sus niveles de actividad física, con el objetivo de mejorar la motivación de los jóvenes deportistas y descender los niveles de aburrimiento en la práctica.

Cosmology-Independent Distance Moduli of 42 Gamma-Ray Bursts between Redshift of 1.44 and 6.60

description: This report is an update and extension of our paper accepted for publication in ApJ (arXiv:0802.4262). Since objects at the same redshift should have the same luminosity distance and the distance moduli of type Ia supernovae (SNe Ia) obtained directly from observations are completely cosmology independent, we obtain the distance modulus of a gamma-ray burst (GRB) at a given redshift by interpolating or iterating from the Hubble diagram of SNe Ia. Then we calibrate five GRB relations without assuming a particular cosmological model, from different regression methods, and construct the GRB Hubble diagram to constrain cosmological parameters. Based upon these relations we list the cosmology-independent distance moduli of 42 GRBs between redshift of 1.44 and 6.60, with the 1-$σ$ uncertainties of 1-3%.

description: Reversed Potts shunt (PS) was suggested as palliation for patients with suprasystemic pulmonary arterial hypertension (PAH) and right ventricular (RV) failure. PS, however, can result in poorly understood mortality. Here, a patient-specific geometrical multiscale model of PAH physiology and PS is developed for a paediatric PAH patient with stent-based PS. In the model, 7.6mm-diameter PS produces near-equalisation of the aortic and PA pressures and Qp/Qs (oxygenated vs deoxygenated blood flow) ratio of 0.72 associated with a 16% decrease of left ventricular (LV) output and 18% increase of RV output. The flow from LV to aortic arch branches increases by 16%, while LV contribution to the lower body flow decreases by 29%. Total flow in the descending aorta (DAo) increases by 18% due to RV contribution through the PS with flow into the distal PA branches decreasing. PS induces 18% increase of RV work due to its larger stroke volume pumped against lower afterload. Nonetheless, larger RV work does not lead to increased RV end-diastolic volume. Three-dimensional flow assessment demonstrates the PS jet impinging with a high velocity and wall shear stress on the opposite DAo wall with the most of the shunt flow being diverted to the DAo. Increasing the PS diameter from 5mm up to 10mm results in nearly linear decrease in post-operative Qp/Qs ratio. In conclusion, this model reasonably represents patient-specific haemodynamics pre- and post-creation of the PS, providing insights into physiology of this complex condition, and presents a predictive tool that could be useful for clinical decision-making regarding suitability for reversed PS in PAH patients with drug-resistant suprasystemic PAH.

description: Whole brain segmentation is an important neuroimaging task that segments the whole brain volume into anatomically labeled regions-of-interest. Convolutional neural networks have demonstrated good performance in this task. Existing solutions, usually segment the brain image by classifying the voxels, or labeling the slices or the sub-volumes separately. Their representation learning is based on parts of the whole volume whereas their labeling result is produced by aggregation of partial segmentation. Learning and inference with incomplete information could lead to sub-optimal final segmentation result. To address these issues, we propose to adopt a full volume framework, which feeds the full volume brain image into the segmentation network and directly outputs the segmentation result for the whole brain volume. The framework makes use of complete information in each volume and can be implemented easily. An effective instance in this framework is given subsequently. We adopt the $3$D high-resolution network (HRNet) for learning spatially fine-grained representations and the mixed precision training scheme for memory-efficient training. Extensive experiment results on a publicly available $3$D MRI brain dataset show that our proposed model advances the state-of-the-art methods in terms of segmentation performance.

description: O objetivo do presente estudo foi o de analisar a associação entre o ritmo musical e o padrão cinemático angular no movimento básico de Hidroginástica “Balanço Lateral”. A amostra foi constituída por seis instrutoras, com pelo menos um ano de experiência na orientação de programas de Hidroginástica. Foram registadas imagens de vídeo no plano frontal do exercício básico de Hidroginástica “Balanço Lateral”, recorrendo a um par de câmaras, proporcionando assim uma dupla projeção do movimento acima e abaixo do nível da água, em cinco ritmos incrementais (120 bpm, 135 bpm, 150 bpm, 165 bpm e 180 bpm). As imagens foram posteriormente digitalizadas e processadas num software específico (Ariel Performance Analysis Systems). Os resultados demonstraram que ocorreu uma diminuição do período do ciclo ao longo do protocolo incremental. O ângulo relativo entre a coxa e o tronco não apresentou relação significativa com o ritmo. Já o ângulo relativo entre a coxa e a perna e entre o braço e o antebraço diminuíram com o aumento do ritmo musical, embora neste último apenas visível para o membro esquerdo. Constata-se assim que existe uma tendência para a diminuição do deslocamento angular e manutenção da velocidade angular com o aumento do ritmo musical ainda que em pontos articulares isolados.

A radiative transfer scheme for cosmological reionization based on a local Eddington tensor

Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: A radiative transfer scheme is presented, based on a moment description of the equation of radiative transfer and the so-called ``M1 closure model'' for the Eddington tensor. This model features a strictly hyperbolic transport step for radiation: it has been implemented using standard Godunov--like techniques in a new code called ATON. Coupled to simple models of ionization chemistry and photo-heating, ATON is able to reproduce the results of other schemes on a various set of standard tests such as the expansion of a HII region, the shielding of the radiation by dense clumps and cosmological ionization by multiple sources. Being simple yet robust, such a scheme is intended to be naturally and easily included in grid--based cosmological fluid solvers.

Repair of DNA damage in mammalian cells after low doses of ionizing radiation
Creators: name: Berger, Stuart Alan
Publisher: name: University of British Columbia
Year: 2010

description: It generally accepted that the critical target of ionizing radiation in cellular reproductive death is DNA. What is less known is what types of lesions are involved, how they are repaired and how various agents enhance, protect or modify them. One of the main reasons for these difficulties has been the lack of assays for molecular damage sensitive enough to measure yields at doses where significant numbers of cells survive. Recently however, various techniques have appeared that exhibit this sensitivity. One of these, Rydbergs’ double-label unwinding method, can routinely detect damage in the DNA of mammalian cells from doses as low as 0.1 Gy. We have used this technique to measure initial yields, repair kinetics and residual yields of damage in the dose range 1-6 Gy. We have found, in substantial agreement with measurements at higher doses, the existence of at least two distinct repair processes with half-lives of 7 minutes and 250 minutes respectively. We have also found that the distribution of breaks between the fast and slow processes can be altered by various conditions; for example: whether or not the irradiation was done in the presence of oxygen or nitrogen, post-treatment in hypertonic solution, incubation with ARA-A, (an inhibitor of DNA synthesis) or post-treatment in dimethyl sulphoxide. We have also found that the yield of unrepaired lesions (as defined by damage remaining after two hours incubation at 37°C) seems to include a quadratic variation with initial dose suggesting that among the slowly repairing breaks, there exist complex, combination-type lesions (which may include DNA double-strand breaks). Such studies, combined with results from other assays should help in understanding the nature of the lesions in DNA and the repair processes acting on them and will eventually aid in identifying the critical lesion(s) responsible for cell death.

description: The concept and design of ammonia as a marine fuel are still in the embryonic stage which requires an in-depth investigation of its applicability in terms of its safety and potential risks, both in the design and operational phases of a ship's lifecycle. The paper examines and compares the state-of-the-art safety regulations, rules, standards and guidelines relevant to ammonia-fuelled ships available in various classification societies reports and international regulations such as the IGF codes and summarises their gaps and limitations. The paper critically analyses three major hazards namely toxicity, chemical corrosion, fire and explosion and their potential impact on the human, environment and ship in the event of ammonia leakage. Various hazardous areas considered include ammonia leakage at the bunkering station, fuel preparation room, engine room and storage room and its impact on the ship's general arrangement. In addition, this study reviews and discusses various qualitative and quantitative risk assessment methods employed in ships using low-flashpoint fuels and their relevance and potential suitability for ships powered by ammonia. The paper concludes with important findings and recommendations to aid designers, operators, safety experts, and policymakers in the further development of safety within the framework of risk assessment and management. Overall, this study provides valuable insights into the safety considerations of using ammonia as a marine fuel and highlights the need for further research and development in this area.

description: We develop a three-dimensional $\mathcal{N}=4$ theory of rigid supersymmetry describing the dynamics of a set of hypermultiplets $(Λ^{αα'\dotα'}_I,\,ϕ^{αA}_I)$ on a curved AdS$_3$ worldvolume background, whose supersymmetry is captured by the supergroup ${\rm D}^2(2,1;\, \boldsymbolα)$. To unveil some remarkable features of this model, we perform two twists, involving the SL$(2,\mathbb R)$ factors of the theory. After the first twist, our spacetime Lagrangian exhibits a Chern-Simons term associated with an odd one-form field, together with a fermionic "gauge-fixing'', in the spirit of the Rozansky-Witten model. The second twist allows to interpret the ${\rm D}^2(2,1;\, \boldsymbolα)$ setup as a framework capable of describing massive Dirac particles. In particular, this yields a generalisation of the Alvarez-Valenzuela-Zanelli model of ''unconventional supersymmetry''. We comment on specific values of the combination $α+1$, which in our model is related to a sort of gauging in the absence of dynamical gauge fields.

description: The present essay focuses on the photographic production of Carl Durheim, lithographer and photographer from Bern (1810-1890). I propose a reading of some of Durheim’s pictures and their reproductions in the existing scholarship. As I will show, unnoticed cuts carried out on the original images led to misleading interpretations because the framing erased key information about the photographer’s working practice. I will reflect on the relationship between the selection of images accompanying a scholarly text and their framing, both intellectual and physical. My attempt is to situate these reflections in the broader context of the early history of photography, which looks at the mutual intersections between graphic- and photographic- processes in the timeframe 1840-1860 in Switzerland. My hope is to integrate all the elements that have been cut and omitted in the standard narratives about a cross section of the early history of Swiss photography.
FLAMES spectroscopy of low-mass stars in the young clusters sigma Ori and lambda Ori

description: Aims. We performed a detailed membership selection and studied the accretion properties of low-mass stars in the two apparently very similar young (1-10 Myr) clusters sigma Ori and lambda Ori. Methods. We observed 98 and 49 low-mass (0.2-1.0 M_sun) stars in sigma Ori and lambda Ori respectively, using the multi-object optical spectrograph FLAMES at the VLT, with the high-resolution (R=17,000) HR15N grating (6470-6790 AA). We used radial velocities, Li and Halpha to establish cluster membership and Halpha and other optical emission lines to analyze the accretion properties of members. Results. We identified 65 and 45 members of the sigma Ori and lambda Ori clusters, respectively and discovered 16 new candidate binary systems. We also measured rotational broadening for 20 stars and estimated the mass accretion rates in 25 stars of the sigma Ori cluster, finding values between 10^-11 and 10^-7.7 M_sun yr^-1 and in 4 stars of the lambda Ori cluster, finding values between 10^-11 and 10^-10.1 M_sun yr-1. Comparing our results with the infrared photometry obtained by the Spitzer satellite, we find that the fraction of stars with disks and the fraction of active disks is larger in the sigma Ori cluster (52+-9% and 78+-16%) than in lambda Ori (28+-8% and 40+-20%) Conclusions. The different disk and accretion properties of the two clusters could be due either to the effect of the high-mass stars and the supernova explosion in the lambda Ori cluster or to different ages of the cluster populations. Further observations are required to draw a definitive conclusion.

description: The generalized (1+1)-D non-linear Schrodinger (NLS) theory with particular integrable boundary conditions is considered. More precisely, two distinct types of boundary conditions, known as soliton preserving (SP) and soliton non-preserving (SNP), are implemented into the classical $gl_N$ NLS model. Based on this choice of boundaries the relevant conserved quantities are computed and the corresponding equations of motion are derived. A suitable quantum lattice version of the boundary generalized NLS model is also investigated. The first non-trivial local integral of motion is explicitly computed, and the spectrum and Bethe Ansatz equations are derived for the soliton non-preserving boundary conditions.

description: In this paper, an abstract framework for the error analysis of discontinuous finite element method is developed for the distributed and Neumann boundary control problems governed by the stationary Stokes equation with control constraints. {\it A~priori} error estimates of optimal order are derived for velocity and pressure in the energy norm and the $L^2$-norm, respectively. Moreover, a reliable and efficient {\it a~posteriori} error estimator is derived. The results are applicable to a variety of problems just under the minimal regularity possessed by the well-posedness of the problem. In particular, we consider the abstract results with suitable stable pairs of velocity and pressure spaces like as the lowest-order Crouzeix-Raviart finite element and piecewise constant spaces, piecewise linear and constant finite element spaces. The theoretical results are illustrated by the numerical experiments.
Towards $\textit{ab initio}$ identification of paramagnetic substitutional carbon defects in hexagonal boron nitride acting as quantum bits

description: Paramagnetic substitutional carbon (C$_\text{B}$, C$_\text{N}$) defects in hexagonal boron nitride (hBN) are discussed as candidates for quantum bits. Their identification and suitability are approached by means of photoluminescence (PL), charge transitions, electron paramagnetic resonance, and optically detected magnetic resonance (ODMR) spectra. Several clear trends in these are revealed by means of an efficient plane wave periodic supercell \textit{ab initio} density functional theory approach. In particular, this yields insight into the role of the separation between C$_\text{B}$ and C$_\text{N}$. In most of the cases the charge transition between the neutral and a singly charged ground state of a defect is predicted to be experimentally accessible, since the charge transition level (CTL) position lies within the band gap. \textit{A posteriori} charge corrections are also discussed. A near-identification of an experimentally isolated single spin center as the neutral C$_\text{B}$ point defect was found via comparison of results to recently observed PL and ODMR spectra.

description: An interesting aspect of complex plasma is its ability to self-organize into a variety of structural configurations and undergo transitions between these states. A striking phenomenon is the isotropic-to-string transition observed in electrorheological complex plasma under the influence of a symmetric ion wakefield. Such transitions have been investigated using the Plasma Kristall-4 (PK-4) microgravity laboratory on the International Space Station (ISS). Recent experiments and numerical simulations have shown that, under PK-4 relevant discharge conditions, the seemingly homogeneous DC discharge column is highly inhomogeneous, with large axial electric field oscillations associated with ionization waves occurring on microsecond time scales. A multi-scale numerical model of the dust-plasma interactions is employed to investigate the role of the electric field on the charge of individual dust grains, the ion wakefield, and the order of string-like structures. Results are compared to dust strings formed in similar conditions in the PK-4 experiment.

Improving Camouflaged Object Detection with the Uncertainty of Pseudo-edge Labels

description: This paper focuses on camouflaged object detection (COD), which is a task to detect objects hidden in the background. Most of the current COD models aim to highlight the target object directly while outputting ambiguous camouflaged boundaries. On the other hand, the performance of the models considering edge information is not yet satisfactory. To this end, we propose a new framework that makes full use of multiple visual cues, i.e., saliency as well as edges, to refine the predicted camouflaged map. This framework consists of three key components, i.e., a pseudo-edge generator, a pseudo-map generator, and an uncertainty-aware refinement module. In particular, the pseudo-edge generator estimates the boundary that outputs the pseudo-edge label, and the conventional COD method serves as the pseudo-map generator that outputs the pseudo-map label. Then, we propose an uncertainty-based module to reduce the uncertainty and noise of such two pseudo labels, which takes both pseudo labels as input and outputs an edge-accurate camouflaged map. Experiments on various COD datasets demonstrate the effectiveness of our method with superior performance to the existing state-of-the-art methods.

description: In low temperature scanning tunneling microscopy (STM) experiments a cerium adatom on Ag(100) possesses two discrete states with significantly different apparent heights. These atomic switches also exhibit a Kondo-like feature in spectroscopy experiments. By extensive theoretical simulations we find that this behavior is due to diffusion of hydrogen from the surface onto the Ce adatom in the presence of the STM tip field. The cerium adatom possesses vibrational modes of very low energy (3-4meV) and very high efficiency (> 20%), which are due to the large changes of Ce-states in the presence of hydrogen. The atomic vibrations lead to a Kondo-like feature at very low bias voltages. We predict that the same low-frequency/high-efficiency modes can also be observed at lanthanum adatoms.

description: This is the first paper in a series aimed at modeling the black hole (BH) mass function, from the stellar to the intermediate to the (super)massive regime. In the present work we focus on stellar BHs and provide an ab-initio computation of their mass function across cosmic times. Specifically, we exploit the state-of-the-art stellar and binary evolutionary code \texttt{SEVN}, and couple its outputs with redshift-dependent galaxy statistics and empirical scaling relations involving galaxy metallicity, star-formation rate and stellar mass. The resulting relic mass function ${\rm d}N/{\rm d}V{\rm d}\log m_\bullet$ as a function of the BH mass $m_\bullet$ features a rather flat shape up to $m_\bullet\approx 50\, M_\odot$ and then a log-normal decline for larger masses, while its overall normalization at a given mass increases with decreasing redshift. We highlight the contribution to the local mass function from isolated stars evolving into BHs and from binary stellar systems ending up in single or binary BHs. We also include the distortion on the mass function induced by binary BH mergers, finding that it has a minor effect at the high-mass end. We estimate a local stellar BH relic mass density of $ρ_\bullet\approx 5\times 10^7\, M_\odot$ Mpc$^{-3}$, which exceeds by more than two orders of magnitude that in supermassive BHs; this translates into an energy density parameter $Ω_\bullet\approx 4\times 10^{-4}$, implying that the total mass in stellar BHs amounts to $\lesssim 1\%$ of the local baryonic matter. We show how our mass function for merging BH binaries compares with the recent estimates from gravitational wave observations by LIGO/Virgo, and discuss the possible implications for dynamical formation of BH binaries in dense environments like star clusters.

description: We show that correlated hopping of triplets, which is often the dominant source of kinetic energy in dimer-based frustrated quantum magnets, produces a remarkably strong tendency to form supersolid phases in a magnetic field. These phases are characterized by simultaneous modulation and ordering of the longitudinal and transverse magnetization respectively. Using Quantum Monte Carlo and a semiclassical approach for an effective hard-core boson model with nearest-neighbor repulsion on a square lattice, we prove in particular that a supersolid phase can exist even if the repulsion is not strong enough to stabilize an insulating phase at half-filling. Experimental implications for frustrated quantum antiferromagnets in a magnetic field at zero and finite temperature are discussed.

description: This guide provides information and considerations for a fair and gender inclusive promotions and

evaluations and gives practical advice to remove gender bias from the process aiming to ultimately

raise the number of female scientists in top level positions. It was written as part of the work package

Career Development in the framework of the project LIBRA - Leading Innovative measures to reach

gender Balance in Research Activities, funded by Horizon2020 programme of the EU, and relies

partly on the experience of 12 members of EU-LIFE, the Alliance of Research Institutes in the Life

Sciences. Due its objective of achieving greater gender balance at the level of senior positions, the

guide will focus on the transition from junior principal investigator (PI) to senior PI. A survey and

director interviews conducted in 2018 at 12 EU-Life research institutes by the Task Force on PI

Selection and Career Development collected the practices in the evaluation and promotion of

faculty. They have helped to develop an exemplary evaluation process to serve as the basis for

practical recommendations to reach gender inclusiveness. This exemplary process can be tailored

to the individual situation.

On the Angular Momentum and Spin of Generalized Electromagnetic Field for $r$-Vectors in $(k,n)$ Space-Time Dimensions

description: This paper studies the relativistic angular momentum for the generalized electromagnetic field, described by $r$-vectors in $(k,n)$ space-time dimensions, with exterior-algebraic methods. First, the angular-momentum tensor is derived from the invariance of the Lagrangian to space-time rotations (Lorentz transformations), avoiding the explicit need of the canonical tensor in Noether's theorem. The derivation proves the conservation law of angular momentum for generic values of $r$, $k$, and $n$. Second, an integral expression for the flux of the tensor across a $(k+n-1)$-dimensional surface of constant $\ell$-th space-time coordinate is provided in terms of the normal modes of the field; this analysis is a natural generalization of the standard analysis of electromagnetism, i. e. a three-dimensional space integral at constant time. Third, a brief discussion on the orbital angular momentum and the spin of the generalized electromagnetic field, including their expression in complex-valued circular polarizations, is provided for generic values of $r$, $k$, and $n$.

description: Using a ten dimensional dual string background, we study aspects of the physics of finite temperature large N four dimensional SU(N) gauge theory, focusing on the dynamics of fundamental quarks in the presence of a background magnetic field. At vanishing temperature and magnetic field, the theory has N=2 supersymmetry, and the quarks are in hypermultiplet representations. In a previous study, similar techniques were used to show that the quark dynamics exhibit spontaneous chiral symmetry breaking. In the present work we begin by establishing the non-trivial phase structure that results from finite temperature. We observe, for example, that above the critical value of the field that generates a chiral condensate spontaneously, the meson melting transition disappears, leaving only a discrete spectrum of mesons at any temperature. We also compute several thermodynamic properties of the plasma.
