Context. This paper presents the first public data release of the S-PLUS Ultra-Short Survey (USS), a photometric survey with short exposure times, covering approximately 9300 deg2 of the Southern sky. The USS utilizes the Javalambre 12-band magnitude system, including narrow, medium, and broad-band filters targeting prominent stellar spectral features. The primary objective of the USS is to identify bright, extremely metal-poor (EMP; [Fe/H] ≤ −3) and ultra-metal-poor (UMP; [Fe/H] ≤ −4) stars for further analysis using medium- and high-resolution spectroscopy.
Aims. This paper provides an overview of the survey observations, calibration method, data quality, and data products. Additionally, it presents the selection of EMP and UMP candidates.
Methods. The data from the USS were reduced and calibrated using the same methods as presented in the S-PLUS DR2. An additional step was introduced, accounting for the offset between the observed magnitudes off the USS and the predicted magnitudes from the very low-resolution Gaia XP spectra.
Results. This first release contains data for 163 observed fields totaling ~324 deg2 along the Celestial Equator. The magnitudes obtained from the USS are well-calibrated, showing a difference of ~15 mmag compared to the predicted magnitudes by the GaiaXPy toolkit. By combining colors and magnitudes, 140 candidates for EMP or UMP have been identified for follow-up studies.
Conclusions. The S-PLUS USS DR1 is an important milestone in the search for bright metal-poor stars, with magnitudes in the range 10 < r ≤ 14. The USS is an ongoing survey; in the near future, it will provide many more bright metal-poor candidate stars for spectroscopic follow-up.

Aims. The most metal-poor tail of the Milky Way ([Fe/H] ≤ −2.5) contains a population of stars on very prograde planar orbits, whose origins and evolution remain puzzling. One possible scenario is that they are shepherded by the bar from the inner Galaxy, where many of the old and low-metallicity stars in the Galaxy are located.
Methods. To investigate this scenario, we used test-particle simulations with an axisymmetric background potential plus a central bar model. The test particles were generated by an extended distribution function (EDF) model based on the observational constraints of bulge stars.
Results. According to the simulation results, a bar with a constant pattern speed is not efficient in terms of helping bring stars from the bulge to the solar vicinity. In contrast, when the model includes a decelerating bar, some bulge stars can gain rotation and move outwards as they are trapped in the bar’s resonance regions. The resulting distribution of shepherded stars heavily depends on the present-day azimuthal angle between the bar and the Sun. The majority of the low-metallicity bulge stars driven outwards are distributed in the first and fourth quadrants of the Galaxy with respect to the Sun and about 10% of them are within 6 kpc from us.
Conclusions. Our experiments indicate that the decelerating bar perturbation can be a contributing mechanism that may partially explain the presence of the most metal-poor stars with prograde planar orbits in the Solar neighbourhood, but it is unlikely to be the only one.
DIES: Parallel dust radiative transfer program with the immediate re-emission method
Authors: Juvela Mika 
Published: August 2024

Context. Radiative transfer (RT) modelling is a necessary tool in the interpretation of observations of the thermal emission of interstellar dust. It is also often part of multi-physics modelling. In this context, the efficiency of radiative transfer calculations is important, even for one-dimensional models.
Aims. We investigate the use of the so-called immediate re-emission (IRE) method for fast calculation of one-dimensional spherical cloud models. We wish to determine whether weighting methods similar to those used in traditional Monte Carlo simulations can speed up the estimation of dust temperature.
Methods. We present the program DIES, a parallel implementation of the IRE method, which makes it possible to do the calculations also on graphics processing units (GPUs). We tested the program with externally and internally heated cloud models, and examined the potential improvements from the use of different weighted sampling schemes.
Results. The execution times of the program compare favourably with previous programs, especially when run on GPUs. On the other hand, weighting schemes produce only limited improvements. In the case of an internal radiation source, the basic IRE method samples the re-emission well, while traditional Monte Carlo requires the use of spatial importance sampling. Some noise reduction could be achieved for externally heated models by weighting the initial photon directions. Only in optically very thin models does weighting – such as the proposed method of forced first interaction – result in noise reduction by a factor of several.
Conclusions. The IRE method performs well for both internally and externally heated models, typically without the need for any additional weighting schemes. With run times of the order of one second for our test models, the DIES program is suitable even for larger parameter studies.
Zur Messung von Behinderung in der Teilhabebefragung und
Teilhabeberichterstattung
Authors: Schäfers Markus 
Published: August 2024

ZusammenfassungDie „Repräsentativbefragung zur Teilhabe von Menschen mit Behinderungen“ (kurz:
Teilhabebefragung) im Auftrag des Bundesministeriums für Arbeit und Soziales
soll im Zusammenspiel mit der Teilhabeberichterstattung dabei helfen, die
Entwicklung der Teilhabe von Menschen mit Behinderungen in Deutschland zu
beurteilen. Teilhabeberichterstattung und Teilhabebefragung nehmen für sich in
Anspruch, Beeinträchtigung und Behinderung gemäß der Internationalen
Klassifikation der Funktionsfähigkeit, Behinderung und Gesundheit (ICF) der
Weltgesundheitsorganisation (WHO) zu operationalisieren. Eine kritische Analyse
des Messkonzepts offenbart methodologische Problemstellen: 1) Das Messkonzept
orientiert sich nicht konsistent an der ICF, weil es Beeinträchtigungen nicht
eindeutig als „impairments“ konzipiert, Umweltfaktoren bei der Bestimmung von
Behinderung nicht hinreichend berücksichtigt und Beeinträchtigung als ursächlich
für Behinderung sieht. 2) Die Abgrenzung zwischen Beeinträchtigung und
Behinderung erfolgt hauptsächlich auf pragmatischer Basis, ohne stimmige
konzeptionelle Begründung. 3) Die gewählte Operationalisierung kann die
angestrebte internationale Vergleichbarkeit nicht gewährleisten. Vorgeschlagen
wird die Integration des „Model Disability Survey“ von WHO und Weltbank in die
Erhebungsinstrumente der deutschen Teilhabebefragung, um eine stärkere
ICF-Orientierung und bessere internationale Vergleichbarkeit zu erreichen. Ein
alternativer Messvorschlag, der mit den vorliegenden Daten umsetzbar ist,
besteht darin, eine Gruppeneinteilung ausschließlich nach der
Beeinträchtigungsstärke vorzunehmen, unter Verzicht auf die a priori
Unterscheidung zwischen Beeinträchtigung und Behinderung. Diese Herangehensweise
nimmt den Grundgedanken der ICF auf, Behinderung als situatives statt als
persönliches Merkmal zu begreifen.

Published: August 2024

ZusammenfassungDer in den späten 90er-Jahren propagierte Mozart-Effekt wurde in 29 Arbeiten
bezüglich Epilepsie näher untersucht, wobei im Allgemeinen der 1. Satz der
Sonate für 2 Klavier KV 448 in häufiger Wiederholung zum Einsatz kam. Damit
wurde bei mindestens einem Fünftel der Patienten eine Reduktion der
Anfallsfrequenz um mehr als 50% erreicht. Patienten mit okzipitalen
epilepsietypischen Mustern sprachen nur selten an. Bezüglich des Wirkmechanismus
scheinen ansonsten melodische Aspekte eine besondere Rolle zu spielen.

Authors: May Benjamin J. , Charalel Resmi A. 
Published: August 2024

AbstractTransarterial treatment of liver tumors is becoming increasingly common and is considered first- or second-line therapy for many tumor types and stages. Such therapies are heavily dependent on imaging during the procedures; while angiography remains the mainstay of intraprocedural therapies, cone beam computed tomography (CBCT) is becoming increasingly commonly used to guide therapy. This article describes the role of CBCT during transarterial therapies and offers guidance as to how CBCT can be optimally used for these procedures.

Abstract
Introduction Colorectal cancer (CRC) is the third most prevalent tumor. Right colon cancer (RCC) comprises one-third of CRC cases and is associated with poorer outcomes, emphasizing the need for optimized treatment strategies. The present study aims to explore the nuances in the management of RCC across Portugal, focusing on surgical approaches and multidisciplinary treatment.
Materials and Methods The CodiReal-PT was a cross-sectional survey-based study adhering to the guidelines of the Checklist for Reporting Results of Internet E-Surveys (CHERRIES), focusing on current practices in RCC oncological surgery. The survey comprised 31 questions divided into 4 sections (demographics, multidisciplinary approach, surgery practices regarding RCC, and postoperative management). It was made available via e-mail to all active members of the Portuguese Society of Surgery (Sociedade Portuguesa de Cirurgia, SPCIR, in Portuguese), and data collection lasted from November to December 2022.
Results Data from 69% of Portuguese public hospitals was obtained. All the participant hospitals had multidisciplinary team meetings to manage CRC cases. However, 17% (n = 6) did not discuss all elective-setting cases during their meetings. Dedicated colorectal surgical teams were present in 86% (n = 31) of hospitals. Furthermore, the presence of these dedicated teams was associated with better practices, namely a higher volume of right colectomies (mean: 51.8 ± 32.6 versus 23.8 ± 4.8; p = 0.001), a preference for the laparoscopic approach (93.5 versus 60.0%; p = 0.021), and standardization of anastomotic techniques (83.9 versus 40.0%; p = 0.029).
Conclusion The present nationwide survey-based study provides a comprehensive landscape of RCC management practices across Portugal, underscoring the significant role of dedicated colorectal surgical teams and the need for further practice standardization. Nevertheless, multidisciplinary team meetings in all surveyed hospitals are an important indicator of improved RCC care. Future research should focus on the impact of specific surgical techniques on oncological outcomes and the potential benefits of centralizing care to high-volume centers.

Published: August 2024

AbstractDespite technical advancements and disease understanding, variceal bleeding remains the leading cause of mortality in patients with cirrhosis. Endoscopic therapies are the main cornerstone of therapy in variceal bleeding. Interventional radiology (IR) plays a significant role in managing variceal bleeding, especially in cases where endoscopic therapies are not feasible or failed. Cross-sectional imaging is often critical to identify relevant anatomy before IR therapies. Transjugular intrahepatic portosystemic shunt (TIPS) is indicated as salvage therapy in patients with refractory variceal bleeding. Retrograde transvenous variceal embolization (RTO) procedures provide superior bleeding control in patients with gastric and ectopic varices, however, without increasing the risk of hepatic encephalopathy and liver function deterioration. Antegrade transvenous obliteration is a viable alternative when RTO is not feasible. Left-sided portal hypertension is a distinct entity resulting from splenic vein stenosis or occlusion, and variceal bleeding in left-sided portal hypertension does not respond to TIPS, requiring variceal embolization, partial splenic embolization, or splenic vein recanalization. Occasionally, endovascular splenorenal or mesorenal shunt and splenic vein occlusion with distal splenorenal diversion are performed to control variceal bleeding. This article entails the basic concepts and procedural aspects of various interventional radiological procedures performed in patients with variceal bleeding.
From a bad to good reputation: a case study illustrating the re-branding of a stigmatized neighbourhood in Sweden
Authors: Sjöberg Magdalena 
Published: August 2024

AbstractNeighbourhoods with low social capital and bad reputations are becoming even more deprived, with increased homelessness, poverty and gang violence. In Sweden, and internationally, there is a need for knowledge of ways to stimulate positive regeneration of neighbourhoods with a bad reputation. This ethnographical case study explores regeneration factors in a neighbourhood that was transformed over 14 years from one with low social capital and a bad reputation to one with higher social capital and a good reputation. Three key factors in this positive regeneration and de-stigmatization process of a neighbourhood with an undesirable reputation were identified: the engagement of private sector actors with place branding and spatial anchorage skills; collaborative co-creation; and home-love with emotion-based building. The findings regarding this successful case highlight the importance of collaboration and including actors with re-branding skills when rewriting the narrative of a stigmatized neighbourhood.

Published: August 2024

In this study, we report a compact and versatile gas sensor system combining mid-infrared interband cascade light emitting diodes (MIR-ICLEDs) with substrate-integrated hollow waveguides (iHWGs) toward miniaturized gas sensors. Two readily exchangeable MIR-ICLEDs with center emission wavelengths of 3.4 µm (2941 cm−1) and 5.7 µm (1754 cm−1), respectively, were integrated into a modular sensor system using the iHWG simultaneously as a miniaturized gas cell. The performance of the sensor system for quantitative analysis was evaluated based on calibration functions established for four analytes (i.e., methane, isobutane, acetone, and acetaldehyde) within the respective spectral regions. The utility of such a sensor system as a non-dispersive infrared sensor was tested for various scenarios, including the application of spectral filters, the performance of the individual ICLEDs, and in the analysis of gas mixtures. Furthermore, we demonstrated that the modularity of the sensor design facilitates flexible adaptation to target gas species and available sample volumes, differentiating individual components within gas mixtures.

Priming enables plants to respond more promptly, minimise damage, and survive subsequent stress events. Here, we aimed to assess the efficacy of priming and cross-priming in mitigating the stress caused by waterlogging and/or dehydration in soybeans (Glycine max). Soybean plants were cultivated in a greenhouse in plastic pots in which soil moisture was maintained at pot capacity through irrigation. The first stress was applied in plants at the vegetative stage for 5 days and involved either dehydration or waterlogging, depending on the treatment. Subsequently, the plants were irrigated or drained and maintained at pot capacity until the second stress. For the second stress, the conditions were repeated in plants at the reproductive stage. We then evaluated the levels of hydrogen peroxide (H2O2), lipid peroxidation, total soluble sugars (TSS), amino acids, proline, and starch, and the activity of antioxidant, fermentative, and aminotransferase enzymes. Under waterlogging and dehydration, priming and cross-priming significantly increased the activity of antioxidant enzymes and the levels of TSS, amino acids, and proline while reducing H2O2 concentration and lipid peroxidation. Under waterlogging, priming suppressed fermentative activity and increased carbohydrate content. This demonstrates that soybean plants activate their defence systems more promptly when subjected to priming.

Published: August 2024

Abstract
The Rutherford cable here was made of 12 single-core MgB2
in-situ wires with an NbTi resistive barrier and a CuNi outer sheath. The uniformity of the wires and cables was analyzed using x-ray microtomography. The critical currents of the wire and cable samples were measured at 4.2 K in the outer fields from 4.0 to 8.0 T, and at 15 K–25 K in fields from 1.0 to 5.5 T. Magnetization AC losses were measured at temperatures of 20 K–40 K, external fields of 0.001–0.1 T and frequencies of 72 and 144 Hz. The obtained results show high engineering current density and reduced losses in the MgB2 cable, which can be especially interesting for windings of superconducting motors or generators.
Optical tomography and coherence of a cavity interacting with two time-dependent position qubits
Authors: Mohamed A-B A , Eleuch H 
Published: August 2024

Abstract
Optical tomography is a widely used method for estimating complex information. It provides a monotonic relation between the coherent field states density and their corresponding probability distributions. This approach is critical for validating any quantum information processing system’s implementation. This paper explores the optical tomography and coherence dynamics for a cavity interacting with two two-level atoms having time-dependent locations. We analyze the dynamics of the photon-field states, as two moving atoms enter a cavity filled with two superposed coherent states. The von-Neumann entropy dynamics illustrates how interaction couplings between the two atoms and cavity can give rise to entangled states under the effects of the atom-field couplings and the time-dependent atomic location parameter. Aside from coherence, the interactions between the cavity and atoms are essential for producing nonclassical proprieties in optical tomography. Furthermore, we investigate the dynamics of optical tomography densities with respect to the couplings between atoms and photons for time-dependent atomic location. Our results show that the couplings between atoms and cavity not only accelerate but also improve the processes involved in generating nonclassical optical tomography and coherence dynamics.
A novel discretization of the Yajima-Oikawa equation: Cauchy matrix approach
Authors: Tian Hong-juan , Silem Abdselam 
Published: August 2024

Abstract
The Cauchy matrix approach, rooted in the Sylvester equation, plays a crucial role in defining the τ functions of nonlinear evolution equations. In this paper, the Cauchy matrix approach is employed to introduce a novel integrable semi-discrete counterpart of the one-dimensional Yajima-Oikawa (YO) system. This new system is linked with the differential-difference Kadomtsev-Petviashvili (KP) equation with self-consistent sources (SCS). Based on the Cauchy matrix approach of the KP system, we systematically construct multiple soliton and multiple pole solutions. Furthermore, we analyze and illustrate various examples of soliton solutions for further understanding.

Abstract
With the rapid development of atom interference technology, multi-loop atom interferometers are widely used in the high-precision measurement of various physical constants and testing of various gravity-related effects. However, in ground-based multi-loop atom interference experiments, the systematic error contribution by classical effects is an important factor that affects the experimental measurement accuracy and gravitational effect detection. Based on this, we used the atomic wave-function evolution-phase accumulation method to provide a high-order interference phase of multi-loop atom interferometers in an inhomogeneous gravitational field containing Earth’s rotation. Furthermore, we propose a new scheme that combines optimised frequency-shift compensation technology with an improved pulse sequence to eliminate systematic errors due to the gravity gradient, Earth’s rotation, and their coupling effect with the pulse duration, as well as the coupling effect of laser detuning with the pulse duration. This study lays a theoretical foundation for experiments on multi-loop atom interferometers with higher precision.
