Authors: Juhi Agrawal, Subodh Pandey, Sachin Chittawar, Vivek Som
Published: January 2024

Introduction

Autonomic dysfunction is common in diabetics and presence of cardiac autonomic neuropathy is responsible for sudden death in diabetics. Detecting subclinical Cardiac Autonomic Neuropathy (CAN) early is crucially important for treatment and for preventing potentially serious consequences of CAN.

Aims and Objectives

The aim of the study is to clinically assess cardiovascular autonomic function tests in type 2 diabetes mellitus patients and compare those with healthy normal subjects.

Method

The study included 60 type 2 diabetic patients including 30 patients without any retinopathy and 30 others with non-proliferative diabetic retinopathy(NPDR), and 60 control subjects matched for age and gender. Autonomic function tests as given by Ewing were performed on all subjects to assess the parasympathetic and sympathetic nervous activity. These tests include heart rate response to deep breathing, valsalsa ratio, 30: 15 ratio, and blood pressure response to standing and sustained hand grip. Statistical analysis of the data was done using One way ANOVA (Analysis of Variance) and multiple comparisons were done using post hoc Tukey Multiple Comparison Test. Statistical significance was set at 0.05.

Results

The results of our study show that there is decrease in cardiovascular autonomic functions more in diabetic patients with NPDR as compared to diabetic patients without retinopathy.

Conclusion

We conclude that there is involvement of both cardiovasvascular sympathetic and parasympathetic nervous system in patients with type 2 diabetes mellitus. So, type 2 DM patients should be evaluated for presence of autonomic dysfunction as early as possible to prevent complications and to improve the prognosis of the disease.
Aortic Stiffness is Associated with Cardiac Function and Cerebral Blood Flow Pulsatility in Type2 Diabetes Mellitus
Authors: Shalini Sharma, Vikram Kala, Vivek Sharma, Prerna Panjeta
Published: January 2024

Introduction

Central hemodynamics has an important role in maintaining appropriate cerebral and other end-organ perfusion and is altered in type2DM. Arterial stiffening is an early phenomenon in patients with type2DM, affecting cardiac function by increasing the cardiac afterload and reducing diastolic coronary artery perfusion, also involving small vessel disease in the brain and subsequent hypoperfusion.

Aims and Objectives

The aim of present study was to determine whether aortic stiffness affects cardiac function and whether central elastic artery stiffness was associated with cerebral blood flow pulsatility and subsequent, cerebral perfusion in type 2 DM patients.

Materials and Method

Fifty six patients with type2DM and 60 age-matched healthy volunteers were enrolled. Aortic PWV was measured using non-invasive cardiovascular risk analysis system (Periscope). Cerebral blood flow was measured by using Trans-Cranial Doppler.

Results

CFPWV of diabetic group showed significantly higher mean values (Group 1=931.00±215.98cm/s Group 2=1241±152.03cm/s) than control subjects (758±151.82). CFPWV was significantly (p value <0.01) increased between two diabetic groups. HbA1c was most significantly correlated to CFPWV (r=1.00, p<0.001) followed by weak correlation between central aortic stiffness quantified by PWV and PI (r=0.5, p>0.01).

Conclusion

In patients with type2DM, aortic stiffness is significantly associated with pulse pressure, aortic pulse pressure, aortic augmentation pressure as well as with cerebral blood flow pulsatility and subsequent cerebral perfusion, contributing to decreased cardiac function and cerebral hypoperfusion. Aortic PWV and TCD measurement might be useful prognostic marker of cardiac and cerebrovascular disease in type2DM.
Relationship of Emotional Intelligence with Pre-Hypertension and its Impact on Autonomic Nervous System as Assessed by Heart Rate Variability in Adult Males
Authors: Sumit Garg, J.L. Agarwal
Published: January 2024

Objectives

 

To compare emotional intelligence score in normotensives and pre-hypertensives.

To compare emotional intelligence score with heart rate variability (HRV)

To compare HRV in normotensives and pre-hypertensives.

 

Methodology

30 pre-hypertensive males and 30 age matched controls of 25-50years of age were enrolled. BP was measured using mercury sphygmomanometer. Pre-hypertension was defined as systolic BP from 121 to 139mm Hg or diastolic BP from 80 to 89mm Hg. Emotional intelligence was measured by Schutte Self-Reported Emotional Intelligence Test and subjects were categorized into two groups: Group A: Low EI (Score <111), Group B: High EI (Score >111) HRV was measured in the supine position for 5 minutes. Frequency domain parameters viz HFnu and LF/HF ratio were used for analysis of autonomic dominance.

Results

Mean EI score was significantly less in pre-hypertensives as compared to controls. Low EI subjects had a significantly lower mean HFnu and a significantly higher mean LF/HF ratio showing lower parasympathetic and higher sympathetic activity in them. Pre-hypertensives had lower mean HFnu and higher LF/HF ratio showing lower parasympathetic and higher sympathetic activity in them.

Conclusions

Low EI subjects are more prone to develop pre-hypertension, had lower parasympathetic & higher sympathetic activity increasing the risk to develop hypertension in future.

Clinical Significance

Beside life style modification, improving EI is an important measure to manage pre hypertension and prevent hypertension.
A Comparative Study of Cognitive Functions among Male and Female Medical Students in a Teaching Hospital of South Kerala
Authors: Prashanth P., Arun Kumar H.P., S. Lincoln Deva Kumar
Published: January 2024

Background

Reaction time (RT) is a measure of the response to a stimulus. RT plays a very important role in our lives as its practical implications may be of great consequences. Factors that can affect the average human RT include age, sex, left or right hand, central versus peripheral vision, practice, fatigue, fasting, breathing cycle, personality types, exercise, and intelligence of the subject.

The Critical Flicker Fusion frequency (CFFF) test provides an index of central nervous system activity or cortical arousal which measures mental arousal and alertness. It is used as an indicator of physical human fatigue, mental work load and cognitive function as well.

Aim

The aim was to compare visual reaction time (VRT), auditory reaction time(ART) and critical flicker fusion frequency on the basis of gender.

Materials and Method

The present comparative study was conducted on 100 healthy medical students in age group of 18–24 years. PC 1000Hz reaction timer was used to measure auditory and visual reaction time. The task was to press the key as soon as the stimulus is presented. Three readings of each stimulus were taken, and their average of three RT's for each stimuli were recorded. Statistical analysis was done using independent sample t test. CFFF was measured by indigenous apparatus. Both ascending and descending frequencies are recorded and average of two is taken as CFFF.

Results

In both the sexes’ RT to the auditory stimulus was significantly less (P < 0.001) as compared to the visual stimulus. Significant difference was found between RT of male and female medical students (P < 0.001) and males have quicker reaction time than females. Males have higher CFFF than females, but statistically not significant.

Conclusion

In the present study, there was no correlation between vitamin D levels and glycaemic control in patients with type 2 diabetes mellitus of Bengaluru city. Since there are conflicting results in the literature, further investigations may be more beneficial to highlight the relationship between glycaemic control and vitamin D.
Neck Circumference as a Novel Measure of Central Obesity in Young Adults: Correlation with other Anthropometric Indices
Authors: Nida Nowreen, Manmeet Kour
Published: January 2024

Background

Obesity is an important yet the most neglected public health problem that has assumed epidemic proportions even in developing countries. Many simple anthropometric indices, including the body mass index (BMI), waist circumference (WC) are being widely used as markers to reflect obesity. In recent years, there has been growing interest in the utility of neck circumference (NC) in identifying people with obesity. This new index of upper body adiposity is quite easy to determine, does not require much body exposure, and is believed to correlate with other obesity indices.

Objectives

This study was undertaken with the purpose to find out the relationship of neck circumference (NC) with other anthropometrical indices.

Materials and Method

This cross sectional study was carried out over a period of six months among 192 medical students. The participants were examined for various anthropometric parameters such as height, weight, and NC. BMI was calculated. The correlation between NC and other indices (BMI, weight WC) was assessed by calculating the Pearson's correlation coefficient (r) and P > 0.05 was taken as statistically significant.

Results

Neck circumference (NC) positively correlated with BMI, weight and WC. The correlation was statistically significant (P < 0.001).

Conclusion

Our study revealed a positive and significant correlation between neck circumference (NC)and other anthropometric indices like BMI, weight and waist circumference (WC) in young medical students, indicating an increase in BMI, weight and waist circumference (WC) with an increase in neck circumference (NC) or vice versa

Published: January 2024

Background & Objectives

Present study was aimed to assess abnormalities of ulnar nerve in stable COPD patients.

Method

Study comprised of 60 healthy adults and 60 stable COPD patients (40–50 years) with no clinical neuropathy. Duration of illness and spirometric indices (FEV1%, FEV1/FVC, PEFR %) were assessed. Nerve conduction study of motor and sensory component of ulnar nerve was recorded bilaterally using RMS EMG MKII. Distal latency, nerve conduction velocity and compound motor action potential (CMAP) and sensory nerve action potential (SNAP) were analysed. Significant abnormality was defined as variations beyond mean ± 2SD from healthy adults.

Results

Observations revealed significantly prolonged distal latency and decreased conduction velocity (demyelination), decreased CMAP (axonal loss) bilaterally of both sensory and motor components of ulnar nerve in COPD patients compared with controls.

Interpretation & conclusion

Observation suggests that hypoxemia of COPD, by inducing direct action on nerve fibres or pontomedullary portion of brain or by enhancing effect of other neurotoxic substances causes nerve impairment

Authors: Jacqueline Maria Dias  , Mini Sara Abraham  , Muhammad Arsyad Subu  , Nabeel Al-Yateem  , Fatma Refaat Ahmed
Published: January 2024

Background: The nursing profession is attracting more male students at the baccalaureate level. Nursing faculty face difficulty in finding appropriate clinical opportunities in obstetrics for male baccalaureate nursing students in the conservative Arab culture.Methods: A simulated environment was created comprising four beds in a ward setting. A standardized patient (SP) was placed on each bed. Each SP was trained to provide a history and respond to triggers based on questions posed by male students. The scenarios were: an antenatal patient admitted for induction of labor, a primipara with edema and severe headache, a multigravida who delivered spontaneously and was preparing for discharge, and a cesarian case on the first postoperative day. In the latter two scenarios, newborns were placed in bassinettes near the SP’s and the male students were also expected to take care of the baby. This innovative educational project highlighted simulation using low fidelity manikins and SPs. Male students reported simulation was an effective teaching strategy to acquire obstetric knowledge and develop critical thinking as they responded to cues given by the SP (e.g., antenatal abdominal pain). In addition, the students gained a level of proficiency in examining antenatal and postnatal women. Furthermore, they reported that debriefing following the training consolidated their learning.Conclusion: Male students reported they would not have been able to achieve the course outcomes for thematernity clinical rotation without the introduction of simulation. This project sets the stage for introducingsimulation into other clinical courses across the baccalaureate curriculum.
Comparison of glycosyl donors: a supramer approach
Authors: Orlova Anna V , Malysheva Nelly N , Panova Maria V , Podvalnyy Nikita M , Medvedev Michael G , Kononov Leonid O
Published: January 2024

The development of new methods for chemical glycosylation commonly includes comparison of various glycosyl donors. An attempted comparison of chemical properties of two sialic acid-based thioglycoside glycosyl donors, differing only in the substituent at O-9 (trifluoroacetyl vs chloroacetyl), at different concentrations (0.05 and 0.15 mol·L−1) led to mutually excluding conclusions concerning their relative reactivity and selectivity, which prevented us from revealing a possible influence of remote protective groups at O-9 on glycosylation outcome. According to the results of the supramer analysis of the reaction solutions, this issue might be related to the formation of supramers of glycosyl donors differing in structure hence chemical properties. These results seem to imply that comparison of chemical properties of different glycosyl donors may not be as simple and straightforward as it is usually considered.

Published: January 2024

This study explored reverse culture shock faced by the first-generation Thai diasporas residing in Western countries upon visiting Thailand. A qualitative research approach guided it. Semi-structured interviews were employed to obtain data from 21 respondents. Thematic analysis revealed that all Thai diaspora tourists experienced reverse culture shock, which could be categorized into five main aspects: cultural, interpersonal, emotional, moral, and environmental. Further, the study suggested that reverse culture shock did not always result from the elements in a home country that caused difficulties, discomfort or unpleasant feelings but could also come from the attributes which tourists sought but could not find in their current country of residence and the realization of the significance of things in their home country that were previously overlooked.

Published: January 2024

Rapid urbanization across the world has drawn attention to the unique state of urban woodlands. New Delhi is one of the world’s most populous cities; yet, it harbours several woodlands that support a variety of wildlife. The persistence of mesopredators like the golden jackal (Canis aureus Linn.) in the city is intriguing and provides an opportunity to explore coexistence in an urban context. Using a combination of camera trapping and occupancy modelling, our study aims to understand the habitat use, distribution, and urban adaptations of the jackal in Delhi’s Central Ridge Reserve Forest. Preliminary analysis shows extensive habitat use and sophisticated adaptations including adjustments in activity patterns in response to human activity and competition from feral dogs. The study also demonstrated behavioural adaptations, particularly in terms of foraging, denning, and coexistence with other species, which enable these urban populations of golden jackals to persist in the city. The study indicates the need for newer frameworks for conservation of synanthropic wild fauna that persist in calorie-rich urban environments.

Fig (Ficus carica L.) cultivation is affronting serious problems caused by biotic and abiotic stresses. Application of in vitro techniques became necessary for plant material sanitation, rapid propagation and conservation. The present study aims the regeneration of in vitro plants of local fig cultivars using different explant types. For that purpose, shoot tips, meristems and leaf segments of 3 local fig cultivars (Soltani, Zidi, Bither Abiadh) and a caprifig (Assafri) were cultivated in vitro. MS media with different concentrations of growth hormones: ?-naphthaleneacetic acid (NAA), indole-3-butyric acid (IBA), 2,4-dichlorophenoxyacetic acid (2,4-D), 6-Benzylaminopurine (BAP), Kinetin (Kin), N6-(2-Isopentenyl)adenine (2iP), Gibberellic acid (GA3) and Thidiazuron (TDZ) and various antioxidants were tested for explants initiation, multiplication and rooting. The combination of 0.2 mg L-1 BAP, 0.1 mg L-1 GA3 and 0.1 mg L-1 NAA was the most appropriate for the best meristem establishment rates. The highest establishment rates were obtained with explants taken in spring for Zidi (62.3%) and Bither Abiadh (96.7%) and in autumn for Assafri (100%). From shoot-tip explants, Zidi gave the highest shoot number during the multiplication step. The rates of leaf fragments regenerating adventitious shoots, reached 75.6% and 57.2%, respectively, for Soltani and Assafri on media enriched by TDZ and IBA. MS medium with 1 mg L-1 IBA allowed the best rooting rates for Bither Abiadh and Assafri explants. Vitroplants in vivo rooting was more effective due to their high success rates and the simplicity of the method. Three months after acclimatization, the survival and success rates of the vitroplants were 80-90%.

Published: January 2024

Dragon fruit cultivation is surging massively because of its high nutritional and medicinal value and profit to the farmers. Micropropagation offers healthy, vigorous and uniform planting material to meet the soaring demand. However, the high cost of tissue-cultured planting material prevents farmers from buying it. Commonly used potting media, peat, perlite, and vermiculite, contribute significantly to the higher cost of micropropagules. In this study, low-cost potting media such as soil, sand and vermicompost were evaluated as alternative potting media for hardening tissue-cultured plants of dragon fruit. Well-rooted micro shoots were transplanted into Protrays containing different proportions of soil, sand and vermicompost and the plant survivability, the number of shoots and roots and their respective length and chlorophyll content were recorded. Sand and vermicompost (1:1 v/v) were found to be the best potting media exhibiting 100% survivability (15 days of hardening of the plants), producing the highest number of shoots (7.66 shoots/plant) with a mean length of shoots (10.61 cm) and 11.27 roots per plant with a mean length of 10.38 cm root length (at 120 days of hardening). Cent per cent survivability was noticed even at 120 days after hardening. Sand and vermicompost, with less than 10% of the cost of peat, perlite and vermiculite may be used as low-cost potting media for the hardening of tissue-cultured plants.

Статья посвящена исследованию поливариантности динамических уравнений теории полуизотропной микрополярной термоупругости. Рассмотрены и проанализированы различные варианты присвоения целых весов полевым переменным с последующим детерминированием алгебраических весов псевдовекторных уравнений динамики полуизотропного термоупругого тела. Этих целей удается достичь, используя псевдоинвариантые элементы объема и площади нечетных целых весов. Кроме того, показано, что нечетный вес может быть приписан псевдовектору спинорных перемещений. В результате чего, тепловой поток, тензор силовых напряжений, массовая плотность, теплоемкость, модуль сдвига также оказываются псевдотензорными величинами нечетного веса, т.е. чувствительны к зеркальным отражениям и инверсиям трехмерного пространства. Обсуждается постулат абсолютной инвариантности абсолютной термодинамической температуры. Получены различные варианты связанной системы дифференциальных уравнений динамики и уравнения теплопроводности для полуизотропного микрополярного термоупругого тела. Обсуждаются вопросы взаимовлияния алгебраических весов определяющих псевдоскаляров с целью учета их реакции на преобразования трехмерного пространства, меняющих его ориентацию на противоположную.

The paper is devoted to the study of dynamic equations polyvariance of the theory of semiisotropic micropolar thermoelasticity. Several variants for assigning integer weights to field variables with subsequent determination of algebraic weights of pseudo-vector equations for the dynamics of a semiisotropic thermoelastic solid are considered and analyzed. For this aim elementary volumes and areas assumed as pseudoinvariants of odd integer weights. In addition, it is shown that odd weights can be assigned to the pseudovector of spinor displacements. As a result, heat flux, force stress tensor, mass density, heat capacity, and shear modulus also can be treated as pseudotensor quantities of odd weights, i.e. manifest itself sensitivity to mirror reflections and inversions of three-dimensional spaces. The fundamental principle of absolute invariance of absolute thermodynamic temperature is discussed. Some variants of the coupled system of differential equations of dynamics and heat conduction equations for a semiisotropic micropolar thermoelastic solid are obtained. The problems of mutual influence of algebraic weights of constitutive pseudoscalars are discussed in order to taking account of their response to transformations of three-dimensional space that change its orientation to the opposite.

The Influence of Corporate Social Responsibility Disclosure, Acceptance of Going Concern Audit Opinion and Audit Quality on Abnormal Returns
Authors: YUDHA Fairas Panca
Published: January 2024

This research aims to examine the influence of CSR disclosure, acceptance of going concern audit opinion and audit quality on market reactions as measured by abnormal returns. The information content in Corporate Social Responsibility (CSR) disclosure, receipt of going concern audit opinion and audit quality are signals from the company that are predicted to cause a market reaction. The sample was obtained using a purposive sampling method and 20 mining sector companies listed on the Indonesia Stock Exchange in 2010-2013 were selected. The analytical method used in this research is multiple regression analysis. The results of hypothesis testing show that CSR disclosure, acceptance of going concern audit opinion, audit quality, company size and asset growth rate simultaneously influence abnormal returns. Meanwhile, partial CSR disclosure, acceptance of going concern audit opinion and audit quality do not affect abnormal returns. This implies that financial information is still a reference for investors in making investment decisions. They do not pay much attention to CSR disclosure information, going concern audit opinion and audit quality as a tool for predicting the future. This also shows that the characteristics of investors in the Indonesian capital market are more long-term oriented.

The results showed that the mechanism of good corporate Governance has an effect on tax avoidance, disclosure of corporate social responsibility has no effect on tax avoidance, the mechanism of good corporate Governance has an effect on firm value, Disclosure of Corporate Social Responsibility has no effect on firm value, Tax Avoidance has a significant effect on firm value in Coal Sector Mining Company Listed on the Indonesia Stock Exchange. Good Corporate Governance positively impacts tax avoidance in small companies, strengthening relationships between shareholders, managers and employees. Disclosure of Corporate Social Responsibility (CSR) influences tax avoidance, but not for large companies that carefully report their finances to benefit stakeholders. CSR is considered a moral obligation, forming the character of an honest manager. Good Corporate Governance also contributes to increasing company value through its mechanisms. However, CSR disclosure does not affect company value. At the same time, high tax avoidance positively impacts company value, reflects profits and gets a positive response from investors in making investment decisions.

Purpose: UD. Setya Abadi D. M is a business unit focusing on the food industry, such as making frozen food (Maryam, churros, tortillas). In carrying out its production activities, this company certainly needs a strategy to compete with other competitors, one of which is forecasting. In this research, the data used is past product sales data from July 2021 to June 2023. This research aims to forecast sales in the future period in order to meet customer needs.Methodology:This data processing uses the weighted moving average and double exponential smoothing methods, which are then tested with the Mean Absolute Percent Error value. Forecasting with the lowest MAPE value is an effective method. The α value used in the double exponential smoothing method from 0.1 to 0.9 is chosen to have the lowest MAPE level: α = 0.6 and α = 0.7. Meanwhile, the weighted moving average method uses three months and four months.Findings: In the MAPE calculation, the results obtained for double exponential smoothing α = 0.6 are 6.45%, and α = 0.7 are 7.14%, while the moving average n = 3 is 13.59%, and n = 4 is 13, 48 %.Implication:It can be concluded that the lowest MAPE value was produced using the DES (Double Exponential Smoothing) method with ???? = 0.6 with a MAPE value of 6.45%. This value is lower than DES ???? = 0.7, 3-month WMA, and 4-month WMA with weights of 0.4, 0.3, 0.2, 0.1.

The Vera C. Rubin Observatory will, over a period of 10 yr, repeatedly survey the southern sky. To ensure that images generated by Rubin meet the quality requirements for precision science, the observatory will use an active-optics system (AOS) to correct for alignment and mirror surface perturbations introduced by gravity and temperature gradients in the optical system. To accomplish this, Rubin will use out-of-focus images from sensors located at the edge of the focal plane to learn and correct for perturbations to the wave front. We have designed and integrated a deep-learning (DL) model for wave-front estimation into the AOS pipeline. In this paper, we compare the performance of this DL approach to Rubin’s baseline algorithm when applied to images from two different simulations of the Rubin optical system. We show the DL approach is faster and more accurate, achieving the atmospheric error floor both for high-quality images and low-quality images with heavy blending and vignetting. Compared to the baseline algorithm, the DL model is 40× faster, the median error 2× better under ideal conditions, 5× better in the presence of vignetting by the Rubin camera, and 14× better in the presence of blending in crowded fields. In addition, the DL model surpasses the required optical quality in simulations of the AOS closed loop. This system promises to increase the survey area useful for precision science by up to 8%. We discuss how this system might be deployed when commissioning and operating Rubin.

We analyze a sample of 3300 galaxies between redshifts z ≃ 3.5 and z ≃ 8.5 selected from James Webb Space Telescope (JWST) images in the Hubble Ultra Deep Field and UKIDSS Ultra Deep Survey field, including objects with stellar masses as low as ≃108
M
⊙ up to z ≃ 8. The depth and wavelength coverage of the JWST data allows us, for the first time, to derive robust stellar masses for such high-z, low stellar mass galaxies on an individual basis. We compute the galaxy stellar mass function, after complementing our sample with ancillary data from CANDELS to constrain the GMSF at high stellar masses (

Our study incorporates a novel method for the estimation of the Eddington bias, which takes into account its possible dependence both on stellar mass and redshift, while allowing for skewness in the error distribution. We finally compute the resulting cosmic stellar mass density and find a flatter evolution with redshift than previous studies.

Published: January 2024

We present a systematic study of the putative hot gas corona around late-type galaxies (LTGs) residing in the Virgo cluster, based on archival Chandra observations. Our sample consists of 21 nearly edge-on galaxies representing a range of star formation rate (SFR) of 0.2–3 M
⊙ yr−1 and a range of stellar mass (M
*) of (0.2–10) × 1010
M
⊙, the majority of which have not been explored with high-sensitivity X-ray observations so far. Significant extraplanar diffuse X-ray (0.5–2 keV) emission is detected in only three LTGs, which are also the three galaxies with the highest SFR. A stacking analysis is performed for the remaining galaxies without individual detection, dividing the whole sample into two subsets based on SFR, stellar mass, or specific SFR. Only the high-SFR bin yields a significant detection, which has a value of L
X ∼ 3 × 1038 erg s−1 per galaxy. The stacked extraplanar X-ray signals of the Virgo LTGs are consistent with the empirical L
X–SFR and L
X–M
* relations found among highly inclined disk galaxies in the field, but appear to be systematically lower than those of a comparison sample of simulated star-forming galaxies in clusters identified from the Illustris-TNG100 simulation. The apparent paucity of hot gas coronae in the sampled Virgo LTGs might be understood as the net outcome of the long-lasting effect of ram pressure stripping exerted by the hot intracluster medium and in-disk star-forming activity acting on shorter timescales. A better understanding of the roles of environmental effects in regulating the hot gas content of cluster galaxies invites sensitive X-ray observations for a large sample of galaxies.

Published: January 2024

We present the study of four far-ultraviolet (FUV) bright stars in the field of the open cluster NGC 2420 using the Ultra Violet Imaging Telescope mounted on AstroSat. The three stars 525, 527, and 560 are members, while star 646 is a nonmember of the cluster. To characterize and determine the parameters of these stars, multiwavelength spectral energy distributions (SEDs) are analyzed using UV, optical, and IR data sets. For all four FUV bright stars, a two-component SED model fits well. Our findings indicate that two stars, 525 and 560, are binary blue straggler star (BSS) systems. These BSS systems may have formed in a tertiary system due to mass transfer from an evolved outer tertiary companion. Star 527 is a binary system of a BSS and an extremely low-mass (ELM) white dwarf, while star 646 is a binary system of a horizontal branch star and an ELM white dwarf. The effective temperatures, radii, luminosities, and masses of the two ELMs are (10250, 11500) K (0.42, 0.12) R
⊙, (1.61, 0.23) L
⊙, and (0.186, 0.170) M
⊙, respectively. The star 527 could be a post-mass-transfer system and may have originated through the Case A/B mass-transfer process in a low-density environment. The cooling age of the ELMs is < 1 Myr, indicating that they have only recently formed.
