Central engine of GRB170817A: Neutron star versus Kerr black hole based on multimessenger calorimetry and event timing
Authors: van Putten Maurice H. P. M. , Della Valle Massimo 
Published: October 2022

Context.LIGO–Virgo–KAGRA observations may identify the remnant of compact binary coalescence and core-collapse supernovae associated with gamma-ray bursts. The multimessenger event GW170817–GRB170817A appears ripe for this purpose thanks to its fortuitous close proximity at 40 Mpc. Its post-merger emission, ℰGW, in a descending chirp can potentially break the degeneracy in spin-down of a neutron star or black hole remnant by the relatively large energy reservoir in the angular momentum,EJ, of the latter according to the Kerr metric.Aims.The complex merger sequence of GW170817 is probed for the central engine of GRB170817A by multimessenger calorimetry and event timing.Methods.We used model-agnostic spectrograms with equal sensitivity to ascending and descending chirps generated by time-symmetric butterfly matched filtering. The sensitivity was calibrated by response curves generated by software injection experiments, covering a broad range in energies and timescales. The statistical significance for candidate emission from the central engine of GRB170817A is expressed by probabilities of false alarm (PFA; type I errors) derived from an event-timing analysis. Probability density functions (PDF) were derived for start-timets, identified via high-resolution image analyses of the available spectrograms. For merged (H1,L1)-spectrograms of the LIGO detectors, a PFAp1derives from causality intsgiven GW170817–GRB17081A (contextual). A statistically independent confirmation is presented in individual H1 and L1 analyses, quantified by a second PFAp2of consistency in their respective observations ofts(acontextual).

Le développement et la structuration de la recherche sur le handicap et la perte d’autonomie en France : État des lieux de l’IReSP
Authors: Bellouze Sarah 
Published: October 2022

Plus d’un milliard de personnes, soit environ 15 % de la population mondiale [1], présentent une forme
ou une autre de handicap. Selon l’enquête Handicap-Santé 2008 de l’INSEE, à l’échelle nationale,
11,5 millions de personnes sont en perte d’autonomie ou en situation de handicap, soit 17,9 % de la
population française. Devant le nombre croissant de personnes reconnues en situation de handicap, et
leurs besoins et attentes insuffisamment couverts par les politiques et normes existantes, il convient
de mettre en place des politiques publiques adaptées et pouvant bénéficier au plus grand nombre.
L’accès à des aides ou dispositifs de droit commun par les personnes en situation de handicap suppose
une planification efficace des politiques publiques et une mise en œuvre adaptée à tous les niveaux
(national, régional et local) et dans tous les secteurs (santé, éducation, emploi, habitat, protection
sociale, transport, etc.). L’inclusion de ces personnes suppose également la mise en place de mesures
spécifiques et de services ciblés.
La recherche sur le handicap et la perte d’autonomie permet aux décideurs publics de mieux appréhender
les enjeux et problématiques auxquels sont confrontées les personnes en situation de handicap. Ils
s’appuient ensuite sur les résultats obtenus par cette recherche pour orienter l’action publique.
Le soutien à la recherche sur le handicap et la perte d’autonomie a fait émerger un milieu de
recherche diversifié et pluridisciplinaire, mais ce champ de recherche s’est inégalement développé
selon le type de handicap.
Ce numéro de Question de Santé Publique a pour objectif de synthétiser un état des lieux de la
recherche française sur le handicap et la perte d’autonomie.

Background Endoscopic and histological remission (ER, HR) are therapeutic targets in ulcerative colitis (UC). Virtual chromoendoscopy (VCE) improves endoscopic assessment and the prediction of histology; however, interobserver variability limits standardized endoscopic assessment. We aimed to develop an artificial intelligence (AI) tool to distinguish ER/activity, and predict histology and risk of flare from white-light endoscopy (WLE) and VCE videos.
Methods 1090 endoscopic videos (67 280 frames) from 283 patients were used to develop a convolutional neural network (CNN). UC endoscopic activity was graded by experts using the Ulcerative Colitis Endoscopic Index of Severity (UCEIS) and Paddington International virtual ChromoendoScopy ScOre (PICaSSO). The CNN was trained to distinguish ER/activity on endoscopy videos, and retrained to predict HR/activity, defined according to multiple indices, and predict outcome; CNN and human agreement was measured.
Results The AI system detected ER (UCEIS ≤ 1) in WLE videos with 72 % sensitivity, 87 % specificity, and an area under the receiver operating characteristic curve (AUROC) of 0.85; for detection of ER in VCE videos (PICaSSO ≤ 3), the sensitivity was 79 %, specificity 95 %, and the AUROC 0.94. The prediction of HR was similar between WLE and VCE videos (accuracies ranging from 80 % to 85 %). The model’s stratification of risk of flare was similar to that of physician-assessed endoscopy scores.
Conclusions Our system accurately distinguished ER/activity and predicted HR and clinical outcome from colonoscopy videos. This is the first computer model developed to detect inflammation/healing on VCE using the PICaSSO and the first computer tool to provide endoscopic, histologic, and clinical assessment.

Arthroscopic Assistance in Surgical Management of Distal Radius Fractures: A Systematic Review and Meta-analysis
Authors: Román-Veas Javier , Gutiérrez-Espinoza Héctor , Campos-Jara Christian , Martínez-García Darío 
Published: October 2022

Abstract
Background Wrist arthroscopy has become a commonly used tool for the management of adults with distal radius fractures (DRFs), although its implementation requires technical competence. This systematic review and meta-analysis appraised the available evidence concerning the contribution of wrist arthroscopy to the functional and radiological outcomes of patients with DRFs operated with arthroscopic assistance.
Methods Randomized control trials were identified through five principal electronic databases on May 31, 2022: Web of Science, Scopus, EBSCO, Embase, and PubMed. Two authors independently performed the search and data extraction and assessed risk of bias (RoB) using the Cochrane RoB tool.
Results A total of 1,780 relevant abstracts and citations were extracted in the preliminary search, which yielded 6 trials that met the eligibility criteria, and 3 studies were included in the quantitative synthesis. The overall pooled mean difference (MD) estimate showed no significant difference in the Disabilities of the Arm, Shoulder, and Hand scores between surgical groups with and without arthroscopic assistance (MD = 0.77 points, 95% confidence interval = −6.58 to 5.03, p = 0.79), with substantial heterogeneity (I2 = 85%).
Conclusion There was low-quality evidence that wrist arthroscopy conveyed not clinically or statistically significant difference to functional outcomes of patients with DRFs. However, our findings are limited by the numbers of studies included and lack of long-term follow-up, although they do provide a good starting point for future quality research.

Published: October 2022

Vibronic interactions in the ground and two excited states of the imidazole radical cation, X2A″ (π−1), A2A′ (nσ−1), and B2A″ (π−1), and the associated nuclear dynamics were studied theoretically. The results were used to interpret the recent photoelectron measurements [M. Patanen et al., J. Chem. Phys. 155, 054304 (2021)]. The present high-level electronic structure calculations employing, in particular, the single, double, and triple excitations and equation-of-motion coupled-cluster method accounting for single and double excitation approaches and complete basis set extrapolation technique for the evaluation of the vertical ionization energies of imidazole indicate that the A 2A′ and B 2A″ states are very close in energy and subject to non-adiabatic effects. Our modeling confirms the existence of pronounced vibronic coupling of the A 2A′ and B 2A″ states. Moreover, despite the large energy gap of nearly 1.3 eV, the ground state X 2A″ is efficiently coupled to the A 2A′ state. The modeling was performed within the framework of the three-state linear vibronic coupling problem employing Hamiltonians expressed in a basis of diabatic electronic states and parameters derived from ab initio calculations. The ionization spectrum was computed using the multi-configuration time-dependent Hartree method. The calculated spectrum is in good agreement with the experimental data, allowing for some interpretation of the observed features to be proposed.
Politeness reciprocity in Shakespeare’s dialogue
Authors: Culpeper Jonathan , Oliver Samuel J. , Tantucci Vittorio 
Published: October 2022

AbstractRecently, it has been proposed that (im)politeness in interaction today is governed in large part by a Principle of (Im)politeness Reciprocity (Culpeper and Tantucci 2021). This paper investigates whether politeness reciprocity works similarly in early modern English – specifically, in the plays of Shakespeare. Focussing on thanking behaviours, the questions of whether politeness reciprocity can be detected, and, if so, how social status might influence the nature of reciprocity, are addressed. The first part of the paper establishes that Early Modern English politeness behaviours were being discussed in terms associated with reciprocity (e.g., metaphors relating to balance and financial/commercial transactions). Then, all the instances of the two main thanking formula patterns (the verbalfirst person pronoun+thanks+second person pronounand the nominalthanks) were extracted from thirty-eight plays attributed wholly or substantially to Shakespeare, and coded for a number of variables, including the weightiness of the gift for which thanks has been given, the amount of effort expended in performing thanks, and the social statuses of the Thanker and Thankee. The results show that reciprocity does govern thanking behaviours, and that social status licences imbalances in those behaviours. The paper also touches on conventionalisation.
Translanguaging in CLIL
Authors: Lisaitė Donata , Smits Tom F. H. 
Published: October 2022

Abstract
Translanguaging was a relatively little-known concept 20 years ago, but has now become a ‘household name’ in
academic contexts. The body of research on translanguaging is ever-growing and the concept covers a vast field from bilinguals’
everyday language use to a theory of language and education. By means of a scoping literature review this study focuses on
translanguaging as a pedagogy within bilingual education and synthesises existing empirical research on the topic that was carried
out between 1990 and 2020.
Generalized Mathisson–Papapetrou–Tulczyjew–Dixon equations
Authors: Ootsuka Takayoshi , Yahagi Ryoko 
Published: October 2022

Abstract
We derive two generalizations of Mathisson–Papapetrou–Tulczyjew–Dixon equations from Casalbuoni–Brink–Schwarz type pseudoclassical Lagrangians of Majorana spinors on a Riemann–Cartan spacetime. One has an additional gauge freedom, which makes the equations of motion also be a generalization of Wong’s equations. The other is a spinor model coupled with a Rarita–Schwinger field to preserve the supersymmetry. The coupling to the torsion is modified due to the existence of the Rarita–Schwinger field. In both extensions, the Tulczyjew condition is automatically satisfied.
An unsupervised convolutional neural network method for estimation of intravoxel incoherent motion parameters
Authors: Huang Hsuan-Ming 
Published: October 2022

Abstract

Objective. Intravoxel incoherent motion (IVIM) imaging obtained by fitting a biexponential model to multiple b-value diffusion-weighted magnetic resonance imaging (DW-MRI) has been shown to be a promising tool for different clinical applications. Recently, several deep neural network (DNN) methods were proposed to generate IVIM imaging. Approach. In this study, we proposed an unsupervised convolutional neural network (CNN) method for estimation of IVIM parameters. We used both simulated and real abdominal DW-MRI data to evaluate the performance of the proposed CNN-based method, and compared the results with those obtained from a non-linear least-squares fit (TRR, trust-region reflective algorithm) and a feed-forward backward-propagation DNN-based method. Main results. The simulation results showed that both the DNN- and CNN-based methods had lower coefficients of variation than the TRR method, but the CNN-based method provided more accurate parameter estimates. The results obtained from real DW-MRI data showed that the TRR method produced many biased IVIM parameter estimates that hit the upper and lower parameter bounds. In contrast, both the DNN- and CNN-based methods yielded less biased IVIM parameter estimates. Overall, the perfusion fraction and diffusion coefficient obtained from the DNN- and CNN-based methods were close to literature values. However, compared with the CNN-based method, both the TRR and DNN-based methods tended to yield increased pseudodiffusion coefficients (55%–180%). Significance. Our preliminary results suggest that it is feasible to estimate IVIM parameters using CNN.
Generation and decay of N2(A3Σu

Abstract
Time-resolved number densities of N2(A3Σu
+, v = 0, 1) molecules in diffuse ns pulse discharge plasmas in N2, N2–H2, N2–CH4, N2–CO2, and N2–CO2–CH4 are measured by tunable diode laser absorption spectroscopy (TDLAS). The first series of measurements is made in the discharge pulse bursts at a relatively low pulse repetition rate (3 kHz), when the N2(A3Σu
+) generation and decay after individual discharge pulses is fully resolved. The second set of data is taken during a sequence of two pulse bursts generated at a higher pulse repetition rate (100 kHz), for different delay times between the first and second bursts. This approach is used to determine the effect of accumulation and decay of reacting species generated in the plasma, including N, H, and O atoms, CO molecules, and C2 hydrocarbon product species, on the rate of N2(A3Σu
+) production and quenching. The effect of these species can be isolated since the rates of N2(A3Σu
+) quenching by the initial reactant species (H2, CH4, and CO2) are slow. Comparison of the measurement results with the kinetic modeling predictions is used to obtain insight into the plasma chemical reaction kinetics. The results complement the measurements of N, H, O, and CO in high-pressure reacting plasmas, and help quantify the plasma chemical processes driven by the electron impact dissociation, electronic excitation, and reactive quenching of the excited electronic states. The present results may be used for the development and validation of higher fidelity kinetic models of reacting plasmas, incorporating state-specific electronic and vibrational energy transfer and chemical reactions.
Development and experimental characterization of a large-capacity magnetorheological damper with annular-radial gap

Published: October 2022

AbstractMagnetorheological (MR) dampers with bypass arrangements and combined annular-radial fluid flow channels have shown superior performance compared to conventional MR dampers with single annular/radial fluid flow gaps. Achieving a higher controllable dynamic force range with low off-state but high on-state damping force is yet a significant challenge for developing MR dampers for high payload ground vehicle suspensions. This paper presents the conceptual design, fabrication, and experimental characterization of a mid-sized large-capacity MR damper equipped with a compact annular-radial MR fluid bypass valve. Extensive experimental tests were conducted to investigate the dynamic characteristics of the proposed MR damper considering wide ranges of excitation frequency, loading amplitude, and electrical current. The equivalent viscous damping and the dynamic range were calculated as functions of loading conditions considered. The proposed damper initially realized the maximum dynamic range and damping force of 2.3 and 5.54 kN, respectively. With MR valve design modifications, the maximum dynamic range and damping force were substantially increased, reaching 5.06 and 6.61 kN, respectively. The effectiveness of the proposed MR damper was subsequently identified by comparing its dynamic range with other conventional MR dampers in previous studies. The results confirmed the superior performance of the proposed MR damper and its potential application for highly adaptive suspension systems for off-road wheeled and tracked vehicles.
Orbital angular momentum for turbulence mitigation in long free-space optical communication links
Authors: Secilmis Gamze Nur , Elmabruk Kholoud 
Published: October 2022

Abstract
The ability of laser beams carrying orbital angular momentum to reduce the scintillation level of Gaussian beam propagating in atmospheric turbulence is numerically investigated. The effect of topological charge, beam waist, operating wavelength and also the receiver radius on the scintillation indices is examined in detail. It is shown that the Gaussian beam carrying orbital angular momentum has a priority over a fundamental Gaussian beam in communication links longer than 2.5 Km. It is clear that Gaussian beams carrying orbital angular momentum in the cases when having a small beam waist and operating at a high wavelength are able seriously to reduce the scintillation index. Accordingly, the presented results will be significant for designing optical communication links that use laser beams carrying orbital angular momentum.
3C-SiC/Si heterostructure for self-powered multiband (UV-VIS) photodetection applications
Authors: Tamay Ilayda M , Teker Kasif 
Published: October 2022

Abstract
This study reports a self-powered 3C-SiC/Si heterostructure photodetector in both metal-semiconductor-metal (MSM) and heterojunction (HET) configurations and capable of operating under ultraviolet and visible light (UV–vis). The single crystalline 3C-SiC thin film was grown epitaxially on a Si (111) substrate by employing a two-step growth process. MSM configuration exhibited a peak responsivity of 0.334 A W−1 and a specific detectivity of 5.4 × 1011 cm.Hz1/2.W−1 (Jones) under white light illumination. However, in the UV region, photocurrent showed an increasing behavior with a decrease in the UV wavelength from 365 nm to 254 nm. The peak responsivity and specific detectivity values of the HET configuration were also determined under white light illumination with 0.167 A W−1 and 4.4 × 1011 Jones, respectively. Furthermore, both devices exhibited very fast rise and decay times as 3.8 ms and 3.6 ms for the MSM, and 6 ms and 8 ms for the HET configuration (fastest reported on 3C-SiC). In brief, our self-powered 3C-SiC/Si heterostructure with multiband (UV–vis) photodetection sensitivity and fast speed could offer new solutions for the eco-friendly and sustainable optoelectronic applications.
