Abstract
We present the discoveries of two giant plants orbiting the red-giant-branch star HD 112570 and the red-clump star HD 154391, based on the radial-velocity (RV) measurements from the Xinglong station and Okayama Astrophysical Observatory. Spectroscopic and asteroseismic analyses suggest that HD 112570 has a mass of 1.15 ± 0.12 M
☉, a radius of 9.85 ± 0.23 R
☉, a metallicity [Fe/H] of −0.46 ± 0.1, and

. We found that HD 154391 b has one of the longest orbital periods among those ever discovered orbiting evolved stars, which may provide a valuable case in our understanding of planetary formation at wider orbits. Moreover, while a mass gap at 4 M

Finally, the origin of the abnormal accumulation near 2 au for planets around large evolved stars (R

Published: January 2024

Abstract
The James Webb Space Telescope (JWST) marks a new era of astronomical observation and discovery, providing unrivaled precision in various measurements, including photometry, morphology, and shear measurement. Accurate point-spread function (PSF) models are essential for many of these measurements. In this paper, we introduce HybPSF, a hybrid PSF construction method for JWST NIRCam imaging data that combines the WebbPSF software, which simulates the PSF for JWST, with observed data to produce more accurate and reliable PSF models. We apply this method to the SMACS J0723 imaging data and construct supplementary structures from residuals obtained by subtracting the WebbPSF PSF model from the data. Our results show that HybPSF significantly reduces discrepancies between the PSF model and the data compared to WebbPSF. Specifically, the PSF shape parameter ellipticity and size comparisons indicate that HybPSF improves precision by approximately 10 times for R
2 and 50% for e. This improvement has important implications for astronomical measurements using JWST NIRCam imaging data.
Extended Stellar Populations in Ultrafaint Dwarf Galaxies

Published: January 2024

Abstract
The possible existence of stellar halos in low-mass galaxies is being intensely discussed nowadays after some recent discoveries of stars located in the outskirts of dwarf galaxies of the Local Group. RR Lyrae stars can be used to identify the extent of these structures, taking advantage of the minimization of foreground contamination they provide. In this work we use RR Lyrae stars obtained from Gaia DR3, the Dark Energy Survey, the Zwicky Transient Facility, and Pan-STARRS1 to explore the outskirts of 45 ultrafaint dwarf galaxies. We associate the stars with a host galaxy based on their angular separations, magnitudes, and proper motions. We find a total of 120 RR Lyrae stars that belong to 21 different galaxies in our sample. We report seven new RR Lyrae stars in six ultrafaint dwarf galaxies (Hydrus I, Ursa Major I, Ursa Major II, Grus II, Eridanus II, and Tucana II). We found a large number of new possible members in Bootes I and Bootes III as well, but some of them may actually belong to the nearby Sagittarius stream. Adding to our list of 120 RR Lyrae stars the observations of other ultrafaint dwarf galaxies that were beyond the reach of our search, we find that at least 10 of these galaxies have RR Lyrae stars located at distances greater than four times their respective half-light radius, which implies that at least 33% of the 30 ultrafaint dwarfs with a population of RR Lyrae stars have extended stellar populations.
Accuracy Analysis for Shack–Hartmann Wave Front Sensing with Extended Sources
Authors: Wei Xiya , Rao Changhui 
Published: January 2024

Abstract
Correlating the Shack–Hartmann wave front sensor (SH-WFS) with extended targets is widely used in solar adaptive optics systems. This paper aims to introduce a theoretical analysis that evaluates the accuracy of the SH-WFS on extended sources, with a specific focus on the implementation of the Normalized Cross-correlation (NCC) algorithm. To obtain an accurate error description, we utilized the calculation formula of the NCC algorithm to directly express the coordinates of the maximum value in the correlation function matrix. Furthermore, we determined the variance of the centroid position through the error transfer function, which quantifies the measurement error. In comparison with the previous findings of Michau et al., our result exhibits a coefficient disparity, specifically obtaining results 1.5 times higher than their work. The extensive solar granulation simulation and experimental results validate the theoretical error formulas. These error formulas can effectively estimate the accuracy of the SH-WFS, providing a theoretical foundation for the design of optical systems.

Abstract
Determining how the galactic environment, especially the high gas densities and complex dynamics in bar-fed galaxy centers, alters the star formation efficiency (SFE) of molecular gas is critical to understanding galaxy evolution. However, these same physical or dynamical effects also alter the emissivity properties of CO, leading to variations in the CO-to-H2 conversion factor (α
CO) that impact the assessment of the gas column densities and thus of the SFE. To address such issues, we investigate the dependence of α
CO on the local CO velocity dispersion at 150 pc scales using a new set of dust-based α
CO measurements and propose a new α
CO prescription that accounts for CO emissivity variations across galaxies. Based on this prescription, we estimate the SFE in a sample of 65 galaxies from the PHANGS–Atacama Large Millimeter/submillimeter Array survey. We find increasing SFE toward high-surface-density regions like galaxy centers, while using a constant or metallicity-based α
CO results in a more homogeneous SFE throughout the centers and disks. Our prescription further reveals a mean molecular gas depletion time of 700 Myr in the centers of barred galaxies, which is overall three to four times shorter than in nonbarred galaxy centers or the disks. Across the galaxy disks, the depletion time is consistently around 2–3 Gyr, regardless of the choice of α
CO prescription. All together, our results suggest that the high level of star formation activity in barred centers is not simply due to an increased amount of molecular gas, but also to an enhanced SFE compared to nonbarred centers or disk regions.

Abstract
Chromospheric differential rotation is a key component in comprehending the atmospheric coupling between the chromosphere and the photosphere at different phases of the solar cycle. In this study, we therefore utilize the newly calibrated multidecadal Ca ii K spectroheliograms (1907–2007) from the Kodaikanal Solar Observatory (KoSO) to investigate the differential rotation of the solar chromosphere using the technique of image cross-correlation. Our analysis yields the chromospheric differential rotation rate Ω(θ) = (14.61 ± 0.04–2.18 ± 0.37

day−1. These results suggest the chromospheric plages exhibit an equatorial rotation rate 1.59% faster than the photosphere when compared with the differential rotation rate measured using sunspots and also a smaller latitudinal gradient compared to the same. To compare our results to those from other observatories, we have applied our method on a small sample of Ca ii K data from Rome, Meudon, and Mount Wilson observatories, which support our findings from KoSO data. Additionally, we have not found any significant north–south asymmetry or any systematic variation in chromospheric differential rotation over the last century.
Délimitation des diagrammes syntaxiques dans la grammaire scolaire
Authors: Gregov Nicolas 
Published: January 2024

Dans cet article, nous proposons une réflexion sur la délimitation des diagrammes syntaxiques dans la grammaire scolaire. En faisant l’hypothèse d’une transposition didactique des diagrammes du savoir savant (les travaux en syntaxe) vers le savoir à enseigner (la grammaire scolaire), nous cherchons à identifier et catégoriser les diagrammes utilisés dans les ouvrages de grammaire scolaire. Face à certaines schématisations au statut incertain, situées entre la phrase et le diagramme prototypique, nous élaborons une grille d’analyse permettant d’évaluer la « diagrammaticité », soit le degré d’iconicité, de ces schématisations. Nous appliquons ensuite cette grille aux diagrammes présents dans trois grammaires scolaires récentes, la Grammaire Bescherelle (2006), le Petit Grevisse (2009) et la Phrase (2015). L’analyse met en évidence une diversité de pratiques diagrammatiques au sein de la grammaire scolaire, tout en soulignant l’influence des savoirs savants.
Le discours du pathétique pour la quête de la solitude dans les confessions, les dialogues et les rêveries du promeneur solitaire de Jean-Jacques Rousseau
Authors: Ndiaye Abdou 
Published: January 2024

Il existe chez l’auteur des promenades, des Confessions, de l’Émile et de la Nouvelle Héloïse une relation particulière qu’il entretient avec l’écriture qui semble fonctionner comme un lieu de mémoire où le persécuté pourra se ressourcer, un lieu favorable à la rédemption et un bouclier sûr contre les attaques de toutes sortes, même celles de ses propres désirs. Ainsi, dans la quête de son identité, plusieurs possibilités s’offrent-elles à lui pour retrouver la stabilité du moi et qui résident dans la manipulation scripturale. Face aux attaques de ses ennemis, comment Rousseau s’érige-t-il en victime ? Le présent article est une étude critique des œuvres autobiographiques de Rousseau. Il a pour objectif de montrer comment cet auteur dispose de son verbe créateur pour appâter le lecteur par les sentiments. Ainsi devant les souffrances, la fuite du temps qui entraîne sa future déchéance, montrerons-nous comment l’élégie, le chant intérieur et l’émotion du style se chargeront de transformer les attaques de ses détracteurs en énergies le rapprochant de son lecteur.

Voix sans discours, discours sans voix : sur quelques anecdotes animalières du xvie siècle
Authors: Huchard Cécile 
Published: January 2024

Les recueils d’histoires admirables ou prodigieuses qui connaissent une grande vogue au xvie siècle font souvent une part importante aux anecdotes animales. Elles croisent croyances et connaissances empruntées aux savoirs antiques, observations éthologiques et visée morale ou édifiante. Alors même que les animaux sont caractérisés, selon la tradition aristotélicienne et la théologie chrétienne, comme dénués de « logos », il s’agit de voir, à partir d’exemples pris chez P. Boaistuau, F. de Belleforest et Camerarius, comment certaines anecdotes mettent en scène des animaux qui semblent « parler » par des comportements signifiants et font valoir des valeurs telles que le juste et l’injuste, amenant, par-delà les interprétations dont ils font l’objet, les auteurs à s’interroger sur la nature animale.
Transcatégorisation grammaticale : focus sur les interrelations entre adjectif qualificatif et adverbe à travers les échanges en ligne entre enseignants
Authors: Taous Tatiana 
Published: January 2024

La contribution étudie la transcatégorisation grammaticale entre adjectif et adverbe et démontre que ce phénomène constitue un angle mort dans le champ de la didactique de la grammaire, alors même qu’il pourrait permettre de résorber les préoccupations des enseignants, telles qu’elles ressortent de leurs échanges informels en ligne. Le travail s’organise en trois temps : un premier point étudie les agoras relatives, de près ou de loin, à la transcatégorisation adjectif-adverbe et détermine les enjeux didactiques de cette question ; nous poursuivons en rappelant la pertinence de ces questionnements au regard de la diachronie et du diasystème du français avant de proposer quelques supports d’énoncés invitant à concevoir la transcatégorisation comme un fait de langue dynamique et, plus largement, à rompre avec une vision normative et autocentrée de la grammaire.
Conceptualizing Fear of Progression in Cardiac Patients: Advancing our Understanding of the Psychological Impact of Cardiac Illness
Authors: Clarke Sarah T. , Murphy Barbara M. , Rogerson Michelle , Grande Michael Le , Hester Robert , Jackson Alun Conrad 
Published: January 2024

Abstract

Background:
An emerging area of psycho-cardiology explores fear of disease progression in cardiac patients, following extensive research of this topic in psycho-oncology. Novel interventions that target cardiac fear of progression(FoP) may be valuable in bridging the gap between the high psychological support needs in cardiac care and limitations surrounding the efficacy of standard psychosocial treatments. However, there appears to be limited research characterizing FoP in cardiac patients with which to inform potential interventions.

Aims:
Using a mixed methods approach in two inter-related studies, we aimed to develop a preliminary conceptualization of cardiac-FoP.

Methods:
Study 1 involved a scoping review of existing qualitative research to identify the range of fears relating to disease progression reported by cardiac patients. Study 2 investigated the prevalence and distress levels associated with a selection of fears identified in Study 1 through a quantitative study of 194 cardiac patient admissions at two Australian hospitals.

Results:
Study 1 conceptualized cardiac-FoP in two ways, by the content of the fears and by the behavioral responses to the fears. Fears were categorized into seven broad domains: fears associated with death, health, interpersonal relationships, treatment, accessing help, role responsibilities, and physical activity. Five categories of behavioral responses were identified: avoidance, hyperawareness, symptom misattribution, seeking help, and lifestyle changes. Study 2 indicated a high prevalence of fear, with an average endorsement of 40.9%. When fear was endorsed, an average of 45.2% of cardiac patients experienced moderate-to-severe distress.

Discussion:
This paper provides an initial conceptualization of FoP in cardiac patients, providing preliminary evidence of the rates of fear and associated distress in this population. Drawing on this conceptualization, unique measurement tools and interventions should be developed to identify and address FoP in cardiac patients.

Abstract

Background:
Determining the clinical and subclinical characteristics related to the recurrence status in patients with a thyroid carcinoma has great significance for prognosis, prediction of recurrence and monitoring of treatment outcomes. This study aimed to determine the association between recurrence rate and some characteristics in patients with thyroid carcinoma.

Patients and Methods:
The study was conducted by descriptive method with longitudinal follow-up on 102 thyroid carcinoma patients at 103 Military Hospital, Hanoi, Vietnam, from July 2013 to December 2016.

Results:
Univariate analysis showed that there was a relationship between the recurrence characteristics in the studied patients and the characteristics of lymph node metastasis (P = 0.026; OR = 15; 95% CI = 1.4–163.2) and BRAF V600E mutation status (P = 0.01; OR = 3.41; 95% CI = 1.31–8.88). When analysing the multivariable Logistic regression model, there was a positive correlation between the occurrence of BRAF V600E gene mutation (P = 0.032; OR = 17.649; 95% CI = 1.290–241.523) and male sex (P = 0.036; OR = 12.788; 95% CI = 1.185–137.961) and the occurrence of recurrence in study patients. The mean time to relapse was earlier in male patients than in female patients (P = 0.02). The mean time to relapse in patients with the BRAF V600E mutation (31.81 ± 1.14 months) was shorter than the mean time to relapse in the group without the mutation (57.82 ± 2.08 months) (P = 0.01). The group of patients with mutations in the BRAF V600E gene increased the risk of recurrence compared with the group without the mutation (HR = 9.14, P = 0.04).

Conclusion:
There is a positive correlation between recurrence and masculinity, lymph node metastasis and the occurrence of BRAF V600E mutations in thyroid carcinoma patients.
Post-COVID-19 Vaccination and Thyrotoxicosis (ASIA Syndrome): Single-Centre Experience from India with Review of Literature
Authors: Singhal Vaibhav , Gupta Sushil 
Published: January 2024

Abstract

Introduction:
Thyrotoxicosis is not uncommon after immunization. It is known as ‘autoimmune/autoinflammatory syndrome by adjuvants (ASIA syndrome)’ and is caused by immunological reaction to adjuvants. However, there is insufficient information on thyrotoxicosis after COVID-19 vaccination in the Indian subcontinent.

Aims/Objectives:
To investigate the spectrum of thyrotoxicosis after COVID-19 immunization.

Settings and Design:
A single-centre retrospective study was conducted at a tertiary care academic institute in India.

Materials and Methods:
We studied the clinical symptoms, biochemical markers, imaging characteristics and treatment of every patient who was diagnosed with thyrotoxicosis within 60 days of receiving the COVID-19 vaccine.

Results:
Following COVID-19 vaccination, we diagnosed ten people (mean age 39.9 years, range 22-63 years) with thyrotoxicosis [Graves’ disease (GD, n-6) and subacute thyroiditis (SAT, n-4)]. The typical duration for symptoms to appear was 2 to 60 days. The majority of patients (n-9) received the COVISHIELD™ vaccine, whereas only one received the COVAXIN® vaccine. After vaccination, two patients with GD developed mildly severe Graves’ orbitopathy, with symptoms emerging two days and sixty days later, respectively. Anti-thyroid drugs (methimazole or carbimazole) were required for all GD patients. All SAT patients were treated conservatively with nonsteroidal anti-inflammatory medications and had positive outcomes.

Conclusions:
SAT, GD and GO may occur as a manifestation of ASIA syndrome, following immunization with COVISHIELD™ and COVAXIN®. Despite the obvious benefits of the COVID-19 vaccine, clinicians should be aware of any potential autoimmune and inflammatory thyroid problems.
Evolving Landscape of Diabetes Epidemic in Southeast Asia: Insights from National Family Health Survey
Authors: Gupta Rahul , Upadhyay Aashish , Kohli Shweta , Khadgwat Rajesh 
Published: January 2024

Abstract

Background:
Limited evidence on diabetes prevalence trends from the Indian subcontinent prompted this study to estimate the trends in diabetes prevalence using the National Family Health Survey (NFHS) data.

Method:
A cross-sectional survey carried out between 2015–2016 (NFHS-4) and 2019–2021 (NFHS-5) in a nationally representative sample of adults (aged 20 to 54 years) was used. Diabetes was defined as the presence of: diagnosed diabetes (self-reported), fasting plasma glucose (FPG) ≥ 126 mg/dl, or a random plasma glucose (RPG) ≥200 mg/dl. “Fasting” was defined as the last food intake >8 hours and “random” as irrespective of the last meal. Diagnosed diabetes was defined as the presence of “self-reported diabetes” and undiagnosed diabetes was defined as FPG > 126 mg/dl or RPG ≥200 mg/dl.

Findings:
The crude prevalence of total diabetes increased from 3.5% (95% confidence interval (CI): 3.46–3.55) in 2015–2016 to 3.99% (95% CI: 3.94–4.04) in 2019–2021, a relative change of 14%. The increase was more in the poorest (1.77% vs 2.48%; P < 0.001) as compared to the rich (5.35%% vs· 5.43%; P = 0.847), rural areas (2.71% vs 3.38%; P < 0.001) as compared to urban (4.95% vs. 5.26%; P = 0.051), in normal weight individuals (1.87% vs. 2.16%; P < 0.001) as compared to obese (7.12% vs. 7.03%; P = 0.384).

Interpretation:
While the absolute prevalence of diabetes is highest amongst individuals residing in urban areas belonging to the rich wealth centile, the relative increase in the prevalence is disproportionately higher in those residing in rural areas, belonging to the poorest wealth centiles and having normal weight.
