Abstract
We aim to investigate the global star formation scenario in star-forming sites AFGL 5157, [FSR2007] 0807 (hereafter FSR0807), [HKS2019] E70 (hereafter E70), [KPS2012] MWSC 0620 (hereafter KPS0620), and IRAS 05331+3115 in the outer Galactic arm. The distribution of young stellar objects in these sites coincides with a higher extinction and H2 column density, which agrees with the notion that star formation occurs inside the dense molecular cloud cores. We have found two molecular structures at different velocities in this direction; one contains AFGL 5157 and FSR0807, and the other contains E70, [KPS2012] MWSC 0620, and IRAS 05331+3115. All these clusters in our target region are in different evolutionary stages and might form stars through different mechanisms. The E70 cluster seems to be the oldest in our sample; AFGL 5157 and FSR0807 formed later, and KPS0620 and IRAS 05331+3115 are the youngest sites. AFGL 5157 and FSR0807 are physically connected and have cold filamentary structures and dense hub regions. Additionally, the near-infrared photometric analysis shows signatures of massive star formation in these sites. KPS0620 also seems to have cold filamentary structures with the central hub but lacks signatures of massive stars. Our analysis suggests molecular gas flow and the hub filamentary star formation scenario in these regions. IRAS 05331+3115 is a single clump of molecular gas favoring low-mass star formation. Our study suggests that the selected area is a menagerie of star-forming sites where the formation of the stars happens through different processes.
UOCS XIV: Study of the Open Cluster NGC 2627 Using UVIT/AstroSat

Abstract
We study the intermediate-age open cluster NGC 2627, located at a distance of ∼2 kpc, using UVIT/AstroSat and other archival data. Using a machine learning-based algorithm, ML-MOC, on the Gaia DR3 data, we identify 422 cluster members, including four blue straggler stars (BSSs), one yellow straggler star (YSS), one blue lurker (BL), one red clump (RC) star, and two binary candidates with detection in both UVIT/F148W and UVIT/F169M filters. We characterise them using multiwavelength spectral energy distributions (SEDs). Out of the above nine sources, one BSS, the BL, and one binary candidate have a source nearby; hence, we did not fit their SEDs. Of the remaining six sources, we successfully fit two with single-component SEDs and four with binary-component SEDs. The binary-component SED-based parameters indicate that the hot companions of BSSs, the YSS, the RC star, and the binary candidate are extremely low-mass white dwarfs, confirming that at least four out of nine stars (44%) are formed via the mass transfer channel. We fit King’s profile function to the high-probability (p > 0.8) cluster members and estimate the cluster core radius (r

C
) to be 3.84′ and the tidal radius (r

t
) to be 36.85′. We find that the equal-mass binaries are most concentrated towards the cluster center, followed by the single massive stars, and single low-mass stars. The BSS population of the cluster is also found to be located within a radius r ∼ 10 × r

C
from the cluster center, suggesting the dynamical evolution of the cluster.

Abstract
We present ultraviolet/optical/near-infrared observations and modeling of Type II supernovae (SNe II) whose early time (δ
t < 2 days) spectra show transient, narrow emission lines from shock ionization of confined (r < 1015 cm) circumstellar material (CSM). The observed electron-scattering broadened line profiles (i.e., IIn-like) of H i, He i/ii, C iv, and N iii/iv/v from the CSM persist on a characteristic timescale (t
IIn) that marks a transition to a lower-density CSM and the emergence of Doppler-broadened features from the fast-moving SN ejecta. Our sample, the largest to date, consists of 39 SNe with early time IIn-like features in addition to 35 “comparison” SNe with no evidence of early time IIn-like features, all with ultraviolet observations. The total sample includes 50 unpublished objects with a total of 474 previously unpublished spectra and 50 multiband light curves, collected primarily through the Young Supernova Experiment and Global Supernova Project collaborations. For all sample objects, we find a significant correlation between peak ultraviolet brightness and both t
IIn and the rise time, as well as evidence for enhanced peak luminosities in SNe II with IIn-like features. We quantify mass-loss rates and CSM density for the sample through the matching of peak multiband absolute magnitudes, rise times, t
IIn, and optical SN spectra with a grid of radiation hydrodynamics and non-local thermodynamic equilibrium radiative-transfer simulations. For our grid of models, all with the same underlying explosion, there is a trend between the duration of the electron-scattering broadened line profiles and inferred mass-loss rate:

Published: July 2024

Abstract
White dwarfs (WDs) polluted by exoplanetary material provide the unprecedented opportunity to directly observe the interiors of exoplanets. However, spectroscopic surveys are often limited by brightness constraints, and WDs tend to be very faint, making detections of large populations of polluted WDs difficult. In this paper, we aim to increase considerably the number of WDs with multiple metals in their atmospheres. Using 96,134 WDs with Gaia DR3 BP/RP (XP) spectra, we constructed a 2D map using an unsupervised machine-learning technique called Uniform Manifold Approximation and Projection (UMAP) to organize the WDs into identifiable spectral regions. The polluted WDs are among the distinct spectral groups identified in our map. We have shown that this selection method could potentially increase the number of known WDs with five or more metal species in their atmospheres by an order of magnitude. Such systems are essential for characterizing exoplanet diversity and geology.
Meridional Flow in the Solar Polar Caps Revealed by Magnetic Field Observation and Simulation

Abstract
As a large-scale motion on the Sun, the meridional flow plays an important role in determining magnetic structure and strength and solar cycle. However, the meridional flow near the solar poles is still unclear. The Hinode observations show that the magnetic flux density in polar caps decreases from the lower latitudes to the poles. Using a surface flux transport model, we simulate the global radial magnetic field to explore the physical process leading to the observed polar magnetic distribution pattern. For the first time, the high-resolution observations of the polar magnetic fields observed by Hinode are used to directly constrain the simulation. Our simulation reproduces the observed properties of the polar magnetic fields, suggesting the existence of a counter-cell meridional flow in the solar polar caps with a maximum amplitude of about 3 m s−1.
A Method of Rapidly Deriving Late-type Contact Binary Parameters and Its Application in the Catalina Sky Survey

Published: July 2024

Abstract
With the continuous development of large optical surveys, a large number of light curves of late-type contact binary systems (CBs) have been released. Deriving parameters for CBs using the the Wilson–Devinney program and the PHOEBE program poses a challenge. Therefore, this study developed a method for rapidly deriving light curves based on the Neural Networks model combined with the Hamiltonian Monte Carlo (HMC) algorithm (NNHMC). The neural network was employed to establish the mapping relationship between the parameters and the pregenerated light curves by the PHOEBE program, and the HMC algorithm was used to obtain the posterior distribution of the parameters. The NNHMC method was applied to a large contact binary sample from the Catalina Sky Survey, and a total of 19,104 late-type contact binary parameters were derived. Among them, 5172 have an inclination greater than 70° and a temperature difference less than 400 K. The obtained results were compared with the previous studies for 30 CBs, and there was an essentially consistent goodness-of-fit (R
2) distribution between them. The NNHMC method possesses the capability to simultaneously derive parameters for a vast number of targets. Furthermore, it can provide an extremely efficient tool for the rapid derivation of parameters in future sky surveys involving large samples of CBs.
Discovery of a Barium Blue Straggler Star in M67 and “Sighting” of Its White Dwarf Companion*
Authors: Pal Harshit , Subramaniam Annapurni , Reddy Arumalla B. S. , Jadhav Vikrant V. 
Published: July 2024

Abstract
We report the discovery of a barium blue straggler star (BSS) in M67, exhibiting enhancements in slow neutron-capture (s-)process elements. Spectroscopic analysis of two BSSs (WOCS 9005 & WOCS 1020) and four stars located near the main-sequence turn-off using GALAH spectra, showed that WOCS 9005 has a significantly high abundance of the s-process elements ([Ba/Fe] = 0.75 ± 0.08, [Y/Fe] = 1.09 ± 0.07, and [La/Fe] = 0.65 ± 0.06). The BSS (WOCS 9005) is a spectroscopic binary with a known period, eccentricity, and a suspected white dwarf (WD) companion with a kinematic mass of 0.5 M
⊙. The first “sighting” of the WD in this barium BSS is achieved through multiwavelength spectral energy distribution (SED) with the crucial far-UV data from the UVIT/AstroSat. The parameters of the hot and cool companions are derived using binary fits of the SED using two combinations of models, yielding a WD with T
eff in the range 9750–15,250 K. Considering the kinematic mass limit, the cooling age of the WD is estimated as ∼60 Myr. The observed enhancements are attributed to a mass transfer (MT) from a companion asymptotic giant branch star, now a WD. We estimate the accreted mass to be 0.15 M
⊙, through wind accretion, which increased the envelope mass from 0.45 M
⊙. The detection of chemical enhancement, as well as the sighting of WD in this system, have been possible due to the recent MT in this binary, as suggested by the young WD.

Abstract
I present the identification of over 4600 new δ Scuti and 4000 new γ Doradus stars, which represent the third phase results of a variability vetting census project in BD, HD, SAO, and PPM catalogs. Across project phases I–III (scanning 468,862 catalog objects), I have identified over 9690 δ Scuti, 7680 γ Doradus, 2600+ Maia variables, 1030+ eclipsing binaries, 20+ RR Lyrae stars, 180+ heartbeat candidates, 9800+ rotating variables (including subtypes of 370+ ELL, 800+ ACV, 100+ SXARI, and hundreds of solar-like oscillators), and several other types as new variables. Notably, more than 120 eclipsing binary systems have been identified with pulsating primary components of either DSCT or GDOR type, while 24 more binaries feature overlapping Maia-type pulsation. Moreover, over 2200 of these variables exhibit hybrid δ Sct-γ Dor pulsations.

Authors: Fournier Mireille 
Published: July 2024

Ces dernières années, les contes (storywork) sont devenus une source incontournable pour certains chercheur.e.s en droit au Canada. L’auteure fait ici le récit de certains travaux de recherche et d’enseignement du droit faits à l’Université de Victoria, située sur les terres des peuples Songhees, Esquimalt et Wsáneć (en Colombie-Britannique, au Canada), la première faculté de droit au Canada qui enseigne de façon comparative le droit des Premières Nations (indigenous law) et la common law canadienne. Passant par une analyse de l’article « Nomos and Narrative » de Robert M. Cover, l’auteure montre ici de quelle façon l’étude des contes (storywork) peut influencer non seulement l’enseignement ou la recherche, mais également la connaissance et la critique du droit.
Le dialogue entre roman et ethnographie chez Zola : le lieu d’une réflexivité ?
Authors: Tettamanti Valeria 
Published: July 2024

Le dialogue chez Zola est abordé ici comme un lieu de réflexivité. Ses ressorts interdiscursifs, entre notes ethnographiques et roman, doivent être pris en compte. Une mise au point conceptuelle et historique de la notion d’« ethnographie », qui est la pierre de touche de la construction romanesque de Zola, ainsi qu’une réflexion sur le statut du dialogue zolien permettent d’aborder la comparaison entre L’Œuvre (1886) et les Dossiers préparatoires . Les conversations des Dossiers préparatoires sont marquées par la préfiguration fictionnelle qui guette le carnet avant même qu’il devienne roman. En retour, la dramatisation des conversations est affectée par la logique documentaire. Dans cette perspective, les dialogues de L’Œuvre , construits entre roman et notes, s’inscrivent dans une esthétique qui régule les « poses » et les prises de position antagonistes de Claude et du père Malgras, ainsi que l’axiologie de la scène actantielle.

Les inscriptions antiques découvertes en Arabie du nord-est et en Arabie du sud, au cours des dernières décennies, comportent des nouveautés souvent passées inaperçues. Il a semblé utile de regrouper ces nouveautés ici. Les deux principales sont la probable extension du royaume de Characène en Arabie du nord-est vers le début de l’ère chrétienne et l’identification du royaume de Tanūkh avec celui d’al-Ḥīra (3e-6e siècles de l’ère chrétienne).
Heteropic Pancreatic Rest in Gall Bladder: Is It Really Worrisome?
Authors: Ansari Sameer Ahmed Abdul Hamid , Alsindi Khalid Ahmed , Bakry Husham 
Published: July 2024

Abstract
Heterotopia of pancreas is defined as an abnormal location of pancreatic tissue devoid of vascular and anatomical connections from main pancreas. The stomach is the most common site of such heterotopia, although the lesion can be encountered throughout the entire gastrointestinal tract. Involvement of gallbladder is extremely rare with few cases reported so far in the literature. We described a similar finding in a 28-year-old female patient, who presented with chronic abdominal pain.
Fluoride Removal from Aqueous Solution Using Thermally Treated Dolomite Powder as Adsorbent in the Fixed Bed Column
Authors: Rudram Chinthayyanaidu , Reddy P. Dinesh Sankar 
Published: July 2024

Abstract

Aim:
The objective of this paper was to investigate the ability of thermally treated dolomite powder (TTDP) to remove fluoride ions from wastewater in a fixed bed column system, and to understand how different operating parameters such as bed height, initial fluoride concentration, and flow rate of influent affected the performance of the system.

Materials and Methods:
The researchers used several different models to analyze the data collected from the column experiments, and they also characterized the TDP adsorbent using field emission scanning electron microscopy and X-ray diffraction in order to understand its surface morphology.

Results:
Adsorption capacity increased with the initial fluoride concentration and decreased with bed height. Saturation concentration increases with an initial concentration of fluoride and decreases with bed height and flow rate of influent. Error analysis between experimental results and model results has been done using different predefined error functions. Regeneration of TDP adsorbent is done using a 1N NaOH solution.

Conclusions:
The breakthrough time increases with a low flow rate of 15 ml/min, low influent concentration of 5 ppm, and higher bed depth of 20 cm. The experimental data from the fixed bed column for fluoride removal are well fitted with all classic models, and the coefficient of regression is close to unity. Regeneration studies have shown that the adsorbent (TTDP) can undergo three cycles of regeneration.
Serum Uric Acid as a Marker of Coronary Artery Disease in Type 2 Diabetes Mellitus Patients: An Observational Study
Authors: Shah Nupur , Singh Reena , Shah Paras , Shah Asha N , Singh Gaurav 
Published: July 2024

ABSTRACT

Background:
Cardiovascular disease is the most prevalent cause of morbidity and mortality in diabetic patients. Hypertension, obesity, and smoking are well-established risk factors for coronary artery disease (CAD) in diabetes. Hyperuricemia is an emerging risk factor for insulin resistance and cardiovascular disease. Our objective in the present study was to assess the association of serum uric acid with cardiovascular disease and its risk factors in type 2 diabetes mellitus.

Methods:
A cross-sectional study was carried out at a tertiary care hospital; a total of 100 patients who presented to the hospital with a diagnosis of type 2 diabetes mellitus were selected by simple random sampling technique and divided into two groups based on echocardiography and coronary angiography reports. Serum uric acid, glycosylated hemoglobin (HbA1c), lipid profile, and body mass index (BMI) measurements were performed. Data were analyzed into the SPSS version, and the Pearson coefficient was used to assess the association between uric acid and cardiovascular disease risk factors. P <0.05 was considered statistically significant.

Results:
The mean uric acid is higher (6.79 ± 1.42 mg/dL) in diabetic patients with CAD compared to diabetics without CAD (4.82 ± 1.66 mg/dL). A positive correlation was found between serum uric acid, BMI, and lipid profile.

Conclusion:
Serum uric acid was significantly associated with the presence of CAD and CAD risk factors and can be used as a predictive marker for cardiovascular outcomes in type 2 diabetes mellitus.
Coexistent Coronary Artery Disease in Patients Undergoing Permanent Pacemaker Implantation - A Study from Major Center in North Eastern India
Authors: Dutta Bornali , Yadav Arun Kumar , Iqbal Farhin 
Published: July 2024

ABSTRACT

Aim:
Data regarding the incidence of coexisting coronary artery disease (CAD) in patients undergoing permanent pacemaker implantation (PPI) in our country are limited. The incidence of coexisting CAD and its clinical characteristic in patients undergoing PPI have not been reported from North-east India. This study has been undertaken to study the incidence of coexisting CAD in patients undergoing PPI with risk factors for CAD or with documented atherosclerotic cardiovascular disease (ASCVD) and also to compare the clinical characteristics between patients with and without CAD.

Materials and Methods:
We prospectively collected data of patients undergoing PPI in our center from June 2020 to December 2021. We evaluated data on indications and clinical characteristics of patients undergoing PPI having risk factors for CAD or with documented ASCVD and also compared the clinical characteristics between patients with and without CAD in the study population.

Results:
A total of 289 subjects underwent PPI during the study period, of which 54 patients were included in the study, who had risk factors for CAD or with documented ASCVD. The mean age of the patients was 62.93 ± 9.06 years. Males outnumbered females with a male-to-female ratio of 5.7:1. CAD was observed in 63% of the study population and 29.6% had obstructive CAD. Patients with CAD were predominantly males (94.1% vs. 69.7%, P = 0.01) and had a statistically significant increase in the incidence of dyslipidemia (79.4% vs. 50%, P = 0.026) and left ventricular (LV) systolic dysfunction (26.5% vs. 5%, P = 0.0544). The incidence of hypertension (70.6% vs. 45%), diabetes (61.8% vs. 35%), smoking (61.8% vs. 55%), and mean age (64.41% vs. 60.4) was also higher in the CAD group though not statistically significant.

Conclusion:
The present study represents the first reported study on the incidence of coexisting CAD in patients undergoing PPI with risk factors for CAD or with documented ASCVD from Northeast India and has observed the incidence to be 63%, of which 29.7% had obstructive disease. Patients undergoing PPI with coexisting CAD were predominantly males and had a statistically significant increase in the incidence of dyslipidemia and LV systolic dysfunction. There was also increase in the incidence of hypertension, diabetes, and smoking in the CAD group though statistically not significant.
