An empirical isochrone archive for nearby open clusters
Authors: Rottensteiner Alena , Meingast Stefan 
Published: June 2024

Context. The ages of star clusters and co-moving stellar groups contain essential information about the Milky Way. Their special properties and placement throughout the galactic disk make them excellent tracers of galactic structure and key components to unlocking its star formation history. Yet, even though the importance of stellar population ages has been widely recognized, their determination remains a challenging task often associated with highly model-dependent and uncertain results.
Aims. We propose a new approach to this long-standing problem, which relies on empirical isochrones of known clusters extracted from high-quality observational data. These purely observation-based data products open up the possibility of relative age determination, free of stellar evolution model assumptions.
Methods. For the derivation of the empirical isochrones, we used a combination of the statistical analysis tool principal component analysis for preprocessing and the supervised machine learning method support vector regression for curve extraction. To improve the statistical reliability of our result, we defined the empirical isochrone of a color-magnitude diagram (CMD) of a cluster as the median calculated from a set of nboot = 1000 curves derived from bootstrapped data. The algorithm requires no physical priors, is computationally fast, and can easily be generalized over a large range of CMD combinations and evolutionary stages of clusters.
Results. We provide empirical isochrones in all Gaia DR2 and DR3 color combinations for 83 nearby clusters (d < 500 pc), which cover an estimated age range of 7 Myr to 3 Gyr. In doing so, we pave the way for a relative comparison between individual stellar populations based on an age-scaling ladder of empirical isochrones of known clusters. Furthermore, due to the exceptional precision of the available observational data, we report accurate lower main sequence empirical isochrones for many clusters in our sample, which are of special interest as this region is known to be especially complex to model. We validate our method and results by comparing the extracted empirical isochrones to cluster ages in the literature. We also investigate the added information that empirical isochrones covering the lower main sequence can provide on case studies of the IC 4665 cluster and the Meingast 1 stream.
Conclusions. The archive of empirical isochrones offers a novel approach to validating age estimates and can be used as an age-scaling ladder or age brackets for new populations and serve as calibration data for further constraining stellar evolution models.

Authors: Ladreyt Alexis , Grezka Aude , Kijima Aï 
Published: June 2024

Le présent article propose un aperçu de l’application dans une perspective lexicographique et contrastive d’un cadre descriptif visant à explorer le fonctionnement d’une sous-catégorie de phraséologismes pragmatiques : les phraséologismes pragmatiques à fonction expressive (désormais PhPex). Le but de cet article est triple : a) décrire le fonctionnement des PhPex ; b) tenter une application de l’approche contrastive à la description de ces objets linguistiques et c), élaborer une modélisation qui sera utile à la fois au chercheur, au traducteur, mais aussi au didacticien et/ou à l’apprenant. Nous tenterons également d’identifier des patrons sémantico-pragmatiques (ou fonction pragmasémantiques chez Tutin et Grossmann 2023) entre le français et le japonais, c’est-à-dire des similarités dans la construction du sens et l’actualisation de la fonction pragmatique qui en découle au sein des expressions étudiées.
Notre exposé se divise en deux temps. Dans un premier temps, nous mettons en lumière les différentes spécificités de ces PhPex et la méthodologie mobilisée dans ce travail de recherche. Dans un second temps, nous étudions le fonctionnement de PhPex employés en contexte d’interactions quotidiennes orales ou médiées informelles dans une perspective contrastive français-japonais. Pour cela, nous nous concentrerons essentiellement sur deux PhPex polylexicaux autonomes à noyau verbal exprimant la colère au travers du motif de la tête : ça me prend la tête ! et 頭に来る！(atama ni kuru => « tête » +prep.+ « venir »). Enfin, nous proposons une synthèse puis nous concluons.
Apport des informations audiovisuelles dans la perception et la production de la consonne /v/ par les apprenants thaïlandais du français

Published: June 2024

Cette étude, s’inscrivant dans le contexte de l’enseignement et de l’apprentissage du français, explore l’une des difficultés récurrentes rencontrées par les apprenants thaïlandais lors du traitement de la consonne non native /v/ : la confusion fréquente avec /w/ en position initiale de syllabe.
Nous avons réalisé une étude pilote expérimentale impliquant huit apprenants thaïlandais de niveaux A1-A2 afin d’évaluer l’impact des informations audiovisuelles sur le traitement des consonnes /f v w/. Deux types de tâches (perception et production) portant sur ces trois consonnes dans deux structures syllabiques (CV, VCV) et quatre contextes vocaliques non arrondis (/i e ɛ a/) ontété menés dans deux modalités distinctes (auditive (A) et audiovisuelle (AV)). En perception, une tâche de discrimination demandait aux participants de juger la similitude entre les stimuli de test et les stimuli de référence. En production, ils répétaient les stimuli perçus précédemment, soit entendus seuls (modalité A), soit entendus et vus (modalité AV). Quatre participants ont été testés en modalité A et quatre en modalité AV.
Les résultats mettent en évidence une nette amélioration du taux de réussite dans la perception et la production de /v/ en modalité AV par rapport à la seule modalité A, quel que soit le type de tâche. De plus, la confusion entre /v/ et /w/ en perception et production est moins fréquente lorsque les apprenants bénéficient à la fois d’informations visuelles et sonores. Par ailleurs, le temps de réponse lors de la perception des consonnes est significativement réduit en modalité AV comparativement à la modalité A. Dans l’ensemble, ces résultats démontrent que les informations audiovisuelles facilitent et accélèrent le traitement de la consonne non native /v/ en position initiale de syllabe chez les apprenants thaïlandais.
L’influence translinguistique dans la perception des consonnes occlusives en français L3 par des apprenants sinophones : une étude exploratoire
Authors: Yang Yufeng , Santiago Fabian 
Published: June 2024

Cet article se concentre sur les influences translinguistiques dans la perception des consonnes occlusives en français L3 par des apprenants sinophones ayant le chinois-mandarin comme L1 et l’anglais comme L2. Pour déterminer les sources d’influences translinguistiques chez les bilingues et les trilingues, nous avons réalisé les tests de discrimination (AX) en perception dans les trois langues avec 37 participants en 6 groupes. Les stimuli consistaient en 36 paires minimales monosyllabiques dans chaque langue. Nos résultats montrent que le pourcentage d’erreurs pour le groupe trilingue est approximativement le même que pour le groupe bilingue du test de perception en français, cependant, pour le temps de réaction, les apprenants plurilingues ont des temps de réaction plus longs que les autres groupes. De plus, nos résultats montrent que les taux de réussite et les temps de réponse ne varient pas en fonction du lieu d’articulation des consonnes.Dans notre étude, l’influence translinguistique sur le français L3 peut provenir soit de la L1, soit de la L2, mais il est peu probable qu’il s’agisse d’une combinaison d’influence translinguistique combinée L1+L2. Plus intéressant encore, il semblerait que la présence de deux langues étrangères déclenche également des efforts cognitifs plus complexes pour la discrimination des consonnes en L1. Ces résultats se conforment aux prédictions des modèles r-SLM, PAM-L2 & LPM.

A Case of Filiform Wart Effectively Treated with Calcarea carbonica
Authors: Garg Khushboo 
Published: June 2024

AbstractWarts are skin growths that are benign (noncancerous) and develop on different parts of the body. These are caused by Human Papilloma Viruses (HPV). Warts are more prevalent in children and teenagers but can affect anyone at any age. Over time, the body's immune system frequently succeeds in battling the viruses, and the warts eventually vanish by themselves. However, people with compromised immune systems may find it considerably harder. Conventional treatment mostly consists of methods such as topical treatments, cryotherapy, ablation, and so on, which may have a variety of adverse effects. The likelihood of recurrence is also high. Here comes the scope of individualized homoeopathic treatment that directs and stimulates the body's self-regulatory mechanisms to restore its natural equilibrium in a cost-effective manner. A casereport of a 20-year-old woman with filiform warts on the scalp is presented here. Calcarea carbonica 200 was prescribed as per the homoeopathic principles which was repeated in 1 M potency. The case was followed up fortnightly. The warts disappeared completely after homoeopathic treatment without the use of any topical applications along with marked improvement in other associated complaints. The total score was 10 on Monarch inventory assessment and +3 on ORIDL (outcome in relation to impact on daily living), suggesting improvement in the overall well-being of the patient. This case report suggests that filiform warts can be successfully treated with individualized homoeopathic medications.

AbstractThe proper closure of the access cavity between appointments during endodontic treatment is paramount and relies on temporary fillings. This systematic review evaluates the effectiveness of zinc oxide-based materials and glass-ionomer cement (GIC) as temporary coronal sealers after root canal treatment in extracted human teeth. Three databases were searched to identify randomized clinical trials that examined the sealing properties of various temporary sealing materials using dyes or stains as indicators. A total of seven in vitro studies that fulfilled the eligibility criteria were critically analyzed. These indicated significant variations in the relative sealing ability of the coronal breach of endodontically treated teeth, either by zinc oxide or GIC-based materials. While GIC-based material (e.g., Fuji IX and Fuji II) exhibited superior sealing of single-rooted teeth, zinc oxide-based material (e.g., Cavit, Coltosol, Caviton) also showed promising attributes. Resin-modified GIC formulations displayed enhanced physical properties, yet challenges related to adhesive failure and shrinkage during polymerization were observed. Zinc oxide-based materials have demonstrated superior coronal sealing effectiveness over certain GIC in controlled settings. Their premixed nature ensures consistent application and hygroscopic properties improve cavity sealing. However, the focus on dye penetration tests for microleakage in vitro may not fully represent the risk of bacterial infiltration. Thus, in vivo studies are crucial for validating these findings in clinical contexts.
Using learner corpus data for grammatical accuracy development in written productions
Authors: Sarré Cédric , Brudermann Cédric , Grosbois Muriel 
Published: June 2024

Abstract
This study investigates the differential effect of various noticing activities on grammatical accuracy development in EFL learners’ written productions. We focus on different types of noticing activities based on an error-tagged learner corpus and report on effective practical experiments involving learner corpus data. A pretest/posttest quasi-experimental design is used with three experimental groups (receiving different treatments) and one control group. Error frequencies, at both group and individual levels, and proportions of learners producing errors on three specific error types (articles, verb tense, verb agreement) are compared. Our results suggest that accuracy in the use of articles and verb agreement could be more easily fostered through the comparison of learner output with native data (the BNC, in our case). As for verb tenses, the impact of a more traditional form of corrective feedback seems greater while the use of online machine translation tools does not seem to foster much accuracy development.

A unified approach to inversion formulae for vector and tensor ray and radon transforms and the Natterer inequality
Authors: Louis Alfred K 
Published: June 2024

Abstract
Most derivations of inversion formulae for x-ray or Radon transform are based on the projection theorem, where for fixed direction the Fourier transform of x-ray or Radon transform is calculated and compared with the Fourier transform of the searched-for function. In contrast to this we start here off from the searched-for field, calculate its Fourier transform for fixed direction, which is now a vector or tensor field, that we then expand in a suitable direction dependent basis. The expansion coefficients are recognized as the Fourier transform of longitudinal, transversal or mixed ray transforms or vectorial Radon transform respectively. The inverse Fourier transform of the searched-for field then directly leads to inversion formulae for those transforms applying problem adapted backprojections. When considering the Helmholtz decomposition of the field we immediately find inversion formulae for those transversal or longitudinal transforms. First inversion formulae for the longitudinal ray transform, similar to those given by Natterer (1986 The Mathematics of Computerized Tomography (Teubner and Wiley)) for x-ray tomography, were given by Natterer-Wübbeling in 2001, Natterer and Wübbeling (2001 Mathematical Methods in Image Reconstruction (SIAM)), but then not pursued by other authors. In this paper, we present the above described method and derive in a unified way inversion formulae for the ray transforms treated in Louis (2022 Inverse Problems
38 065008) containing the results from Louis (2022 Inverse Problems
38 065008) as special cases. Additionally we present new inversion formulae for the vectorial Radon transform. As a consequence the inversion formulae directly give Plancherel’s formulae for the vectorial or tensorial transforms. Together with the Natterer inequality, which is independent of the ray or Radon transforms, we present the Natterer stability of those vectorial and tensorial transforms.
Recent progress in 2D textile-based piezoresistive strain and pressure sensors
Authors: Raman Srinivasan , Sankar A Ravi 
Published: June 2024

Abstract
The integration of electronic functionalities into textiles has been under extensive research as its application is witnessed in various fields, including sensing, energy generation, storage, displays, and interfaces. Textiles endowed with flexibility, comfort, lightweight, and washability have been tested as reliable base materials to implement various physical sensors, of which strain and pressure sensors have shown great potential in applications such as healthcare, fitness tracking, and human-machine interaction. Piezoresistive physical sensors have considerable advantages over capacitive and piezoelectric sensors made of textiles. Apart from fibers, yarns, and threads, two-dimensional textile stripes occupy a significant share as substrates in these sensors. This review article discusses the recent progress of 2D textile-based piezoresistive strain and pressure sensors. It covers the latest works in this domain, focusing on different textile choices, conductive material combinations, fabrication methods, additional functionalities like heating, features like hydrophobic properties, and various applications, with tabulations of key performance metrics. For researchers seeking an update on the state of the field, this review would be helpful as it offers insights into trends for further research and product development aimed at meeting the demands of advanced healthcare and other applications.
A proposed device based on MoSe2-ZnO heterojunctions on rGO for enhanced ethanol gas sensing performances at room temperature
Authors: Jain Nikita , Puri Nitin K 
Published: June 2024

Abstract
In this research, we report an enhanced sensing response ethanol gas sensing device based on a ternary nanocomposite of molybdenum diselenide-zinc oxide heterojunctions decorated rGO (MoSe2/ZnO/rGO) at room temperature. The sensing performance of the ternary nanocomposite sensing device has been analysed for various concentrations of ethanol gas (1–500 ppm). The gas-sensing results have revealed that for 500 ppm ethanol gas concentration, the sensing device has exhibited an enhanced response value

of 50.2. Significantly, the sensing device has displayed a quick response and recovery time of 6.2 and 12.9 s respectively. In addition to this, the sensing device has shown a great prospect for long-term detection of ethanol gas (45 days). The sensing device has demonstrated the ability to detect ethanol at remarkably low concentrations of 1 ppm. The enhanced sensing performance of the ternary nanocomposite sensing device has highlighted the effective synergistic effect between MoSe2 nanosheets, ZnO nanorods, and rGO nanosheets. This has been attributed to the formation of two heterojunctions in the ternary nanocomposite sensor: a p-n heterojunction between MoSe2 and ZnO and a p-p heterojunction between MoSe2 and rGO. The analysis of the results has suggested that the proposed MoSe2/ZnO/rGO nanocomposite sensing device could be considered a promising candidate for the real-time detection of ethanol gas.
Structure-aware diffusion for low-dose CT imaging
Authors: Du Wenchao , Cui HuanHuan , He LinChao , Chen Hu , Zhang Yi , Yang Hongyu 
Published: June 2024

Abstract
Reducing the radiation dose leads to the x-ray computed tomography (CT) images suffering from heavy noise and artifacts, which inevitably interferes with the subsequent clinic diagnostic and analysis. Leading works have explored diffusion models for low-dose CT imaging to avoid the structure degeneration and blurring effects of previous deep denoising models. However, most of them always begin their generative processes with Gaussian noise, which has little or no structure priors of the clean data distribution, thereby leading to long-time inference and unpleasant reconstruction quality. To alleviate these problems, this paper presents a Structure-Aware Diffusion model (SAD), an end-to-end self-guided learning framework for high-fidelity CT image reconstruction. First, SAD builds a nonlinear diffusion bridge between clean and degraded data distributions, which could directly learn the implicit physical degradation prior from observed measurements. Second, SAD integrates the prompt learning mechanism and implicit neural representation into the diffusion process, where rich and diverse structure representations extracted by degraded inputs are exploited as prompts, which provides global and local structure priors, to guide CT image reconstruction. Finally, we devise an efficient self-guided diffusion architecture using an iterative updated strategy, which further refines structural prompts during each generative step to drive finer image reconstruction. Extensive experiments on AAPM-Mayo and LoDoPaB-CT datasets demonstrate that our SAD could achieve superior performance in terms of noise removal, structure preservation, and blind-dose generalization, with few generative steps, even one step only.
Convergence of resonant state expansions for transmission in double delta resonators
Authors: Villavicencio Jorge , Hernández-Maldonado Alberto 
Published: June 2024

Abstract
We investigate the transmission features of symmetric double Dirac delta resonators using a non-Hermitian quantum approach, based on resonant state expansions involving complex energy eigenvalues. We focus on the convergence properties of these expansions, which involve a sum of resonance and anti-resonance terms We demonstrate that systems with transmission profiles featuring sharp and isolated resonances converge more rapidly, whereas those with overlapping resonances exhibit slower convergence. We also show that for the former systems, by taking into account only the resonance terms, we can accurately describe the transmission coefficient as a sum of Breit-Wigner resonances, each distinctly characterized by its energy and width. We demonstrate that there is a one-to-one correlation between transmission peaks and the resonance energies of the system. We also compare the convergence properties of transmission using Mittag-Leffler expansions, noting their slower rates compared to resonant state expansions. These findings emphasize the advantage of using non-Hermitian resonant expansions for analyzing quantum mechanical systems, providing a clearer understanding of systems characterized by resonant features.
