Abstract
We have performed a spectral-timing analysis of the black hole X-ray binary MAXI J1535-571 during its 2017 outburst, with the aim of exploring the evolution of the inner accretion flow geometry. X-ray reverberation lags are observed in the hard-intermediate state (HIMS) and soft-intermediate state of the outburst. During the HIMS, the characteristic frequency of the reverberation lags ν
0 (the frequency at which the soft lag turns to zero in lag–frequency spectra) increases when the spectrum softens. This reflects a reduction of the spatial distance between the corona and accretion disk, when assuming the measured time lags are associated with the light travel time. We also find a strong correlation between ν
0 and the type-C quasi-periodic oscillation (QPO) centroid frequency ν
QPO, which can be well explained by the Lense–Thirring precession model under a truncated disk geometry. Despite the degeneracy in the spectral modeling, our results suggest that the accretion disk is largely truncated in the low hard state, and moves inward as the spectrum softens. Combine the spectral modeling results with the ν
0 – ν
QPO evolution, we are inclined to believe that this source probably has a truncated disk geometry in the hard state.

Published: August 2023

Abstract
We present a Bayesian graph neural network (BGNN) that can estimate the weak lensing convergence (κ) from photometric measurements of galaxies along a given line of sight (LOS). The method is of particular interest in strong gravitational time-delay cosmography (TDC), where characterizing the “external convergence” (κ
ext) from the lens environment and LOS is necessary for precise Hubble constant (H
0) inference. Starting from a large-scale simulation with a κ resolution of ∼1′, we introduce fluctuations on galaxy–galaxy lensing scales of ∼1″ and extract random sight lines to train our BGNN. We then evaluate the model on test sets with varying degrees of overlap with the training distribution. For each test set of 1000 sight lines, the BGNN infers the individual κ posteriors, which we combine in a hierarchical Bayesian model to yield constraints on the hyperparameters governing the population. For a test field well sampled by the training set, the BGNN recovers the population mean of κ precisely and without bias (within the 2σ credible interval), resulting in a contribution to the H
0 error budget well under 1%. In the tails of the training set with sparse samples, the BGNN, which can ingest all available information about each sight line, extracts a stronger κ signal compared to a simplified version of the traditional method based on matching galaxy number counts, which is limited by sample variance. Our hierarchical inference pipeline using BGNNs promises to improve the κ
ext characterization for precision TDC. The code is available as a public Python package, Node to Joy

Abstract
This paper reports the estimated stellar parameters of 1153 Kepler red giant branch stars determined with asteroseismic modeling. We use radial-mode oscillation frequencies, gravity-mode period spacings, Gaia luminosities, and spectroscopic data to characterize these stars. Compared with previous studies, we find that the two additional observed constraints, i.e., the gravity-mode period spacing and luminosity, significantly improve the precision of fundamental stellar parameters. The typical uncertainties are 2.9% for the mass, 11% for the age, 1.0% for the radius, 0.0039 dex for the surface gravity, and 0.5% for the helium core mass, making this the best-characterized large sample of red giant stars available to date. With better characterizations for these red giants, we recalibrate the seismic scaling relations and study the surface term on the red giant branch. We confirm that the surface term depends on the surface gravity and effective temperature, but there is no significant correlation with metallicity.
A comparative study to assess the job stress levels among faculty members in medical institutions
Authors: Kumar B. Senthil , Shastri Deepti , Vendhan K. Ezhil 
Published: August 2023

ABSTRACT

Background:
For many people, stress is so common that it has become a part of life. When it is within a limit, it can help to perform under pressure and motivate to do our best. But when it exceeds and constantly running in an emergency mode, mind and body both are affected. Stress accounts for 80% of all illnesses either directly or indirectly. Stress weakens the immune system and has various effects on the brain and body involving cardiovascular problems, mental illness, depression, etc.,

Aims:
To assess the stress levels among faculty working in medical institutions and to study the need and techniques of stress management.

Materials and Methods:
The proposed study was conducted as a survey using a structured validated questionnaire among the faculty working in VMKVMCH, Salem and other medical institutions. The survey was analyzed and stress level was assessed and correlated.

Results:
Efforts must be made to hire adequate, well trained and efficient faculty, discuss grievances with the faculty and take appropriate actions to alleviate stress & anxiety. A significant measure from the administrator’s point of view would be to recognize the importance of personal lives of the faculty which may, at times be prioritized over office work. Effective coping strategies need to be adopted by administrators including Stress Management Training, periodical retreats, engaging counselors / medical experts / psychologists to provide support and established stress free working environment.

Conclusion:
The study concludes that excessive workload due to under staffing and preposterous deadlines contribute majorly to work related stress. It is recommended that the management and administrators recruit and train more faculty and delegate some of the responsibilities to them; ensure equitable distribution of work; address grievances of faculty as soon as possible and provide de-stressing and rejuvenating measures like office parties and supportive counseling by professionals.
Overview of the artificial intelligence roadmap: Future applications in brain research
Authors: Bohra Deepika , Rana Rashmi , Ganguly Nirmal Kumar 
Published: August 2023

ABSTRACT
The use of artificial intelligence (AI) is an emerging technique in the early identification and categorisation of brain tumour. The currently used method, i.e., magnetic resonance image for the detection of tumour is a time–consuming and complex technique. In the newly developing technique using the AI, the magnetic resonance image scans are used as input data, whereas the currently used method reads the magnetic resonance image manually. The purpose of this article is that the use of novel technique seems very promising in the early detection of brain tumour with high sensitivity and specificity. In this article, two disciplines of AI – machine learning and deep learning are extensively discussed. Through the utilisation of AI techniques, the fields of medicine and health care have experienced remarkable advancements, still there is a shortage of knowledge on artificial–based methods for early tumour diagnosis and classification. In addition, the article discusses the future application of AI techniques in clinical studies.

Published: August 2023

Background:
Dissociative disorder is a condition characterized by disruption of the normal continuity and integration of consciousness, memory, identity, motor functioning, and behavior.

Aims:
The aim of the study was to study the various psychosocial factors that influence the dissociative episodes in patients. We also looked at the clinical profile and the relation between the type and levels of dissociation with levels of stress in the study sample.

Materials and Methods:
This descriptive, cross-sectional study with serial sampling had 50 participants who were diagnosed with dissociation as per the International Classification of Diseases-10 criteria. The study was conducted after obtaining clearance from the institutional ethics committee. Dissociative experience of the patients was measured using Severity of Dissociative Symptoms-Adult (Brief Dissociative Experiences Scale [DES-B]-Modified) and stress levels were measured using Presumptive Stressful Life Events Scale.

Results:
The study showed that dissociation was more common among females from urban population, who were single and among students. Dissociative convulsions were found to be the most common type of dissociation in our culture. DES-B showed moderate-to-severe types of dissociative experience in the sample. In 46% of the participants, family conflicts acted as the most common stressor precipitating episodes. There was a psychodynamic connection/explanation between the perceived stress and the presenting complaint.

Conclusion:
This study highlights the common dissociations, stressors, and the difference seen among males and females. There is a need to understand the stressors of a patient presenting with dissociation for better psychological management.

Published: August 2023

Abstract

Introduction:
Depression is a chronic debilitating illness that causes functional impairment significantly affecting physical, mental, and social well-being of the individual, further impacting lives of their relatives. Majority of studies done in the past were on caregivers of patients suffering from schizophrenia, bipolar disorder, or chronic physical illnesses.

Methods:
We assessed caregiver burden in the caregivers of depressive disorder patients by using Montgomery Borgatta Caregiving Burden Scale.

Results:
The study population had significantly higher proportion of subjective stress burden (70%) whereas subjective demand burden and objective burden were seen in 22.5% and 37.5% of caregivers respectively. Younger age, female, spouses, and nuclear family type were significantly associated with the presence of caregiver burden.

Conclusion:
High prevalence of caregiver burden was observed in caregivers of depressive disorder patients, which could predispose caregivers to develop psychiatric comorbidities. Thus, early interventions and teaching them better coping strategies could help in the reduction of caregiver distress.
“The Big Three” of geriatrics: A review of perioperative cognitive impairment, frailty and malnutrition

Published: August 2023

ABSTRACT
Cognitive impairment, frailty, and malnutrition are three of the most impactful pathologies facing an aging population, having dramatic effects on morbidity and mortality across nearly all facets of medical care and intervention. By 2050, the World Health Organization estimates that the population of individuals over the age of sixty worldwide will nearly double, and the public health toll of these demographic changes cannot be understated. With these changing demographics comes a need for a sharpened focus on the care and management of this vulnerable population. The average patient presenting for surgery is getting older, and this necessitates that clinicians understand the implications of these pathologies for both their immediate medical care needs and for appropriate procedural selection and prognostication of surgical outcomes. We believe it is incumbent on clinicians to consider the frailty, nutritional status, and cognitive function of each individual patient when offering a surgical intervention, as well as consider interventions that may delay the progression of these pathologies. Unfortunately, despite excellent evidence supporting things like routine pre-operative frailty screening and nutritional optimization, many interventions that would specifically benefit this population still have not been integrated into routine practice. In this review, we will synthesize the existing literature on these topics to provide a pragmatic approach and understanding for anesthesiologists and intensivists faced with this complex population.
Preoperative optimization: Physical and cognitive pre-habilitation and management of chronic medication
Authors: Trottier Miguel , Carli Francesco 
Published: August 2023

ABSTRACT
Surgery is a significant stressor for older patient. Most are at higher risk of complications due to frailty and comorbidities. This article will review the impact of surgery on the older patient, perioperative risk assessment and stratification, prehabilitation, and specific screenings and interventions. Electronic searches of PubMed were conducted to identify relevant literature using the following search terms: prehabilitation, sarcopenia, osteosarcopenia, frailty, perioperative evaluation, and polypharmacy. Using the frailty phenotype allows for the early identification of geriatric syndromes and potential targets for interventions. However, it does not inform on potential cognitive impairment, which must be assessed separately. Prehabilitation, especially using multimodal interventions, aims to increase functional capacity during the preoperative period in anticipation of the upcoming stress of surgery and the metabolic cost of recovery. It comprises aerobic and resistance training, dietary interventions, psychological interventions, and cessation of adverse health behaviors. Addressing polypharmacy is also important during the perioperative period. Several frailty assessment tools exist, and special tests only take minutes to perform such as the gait speed and chair stand test. Early identification by surgeons leads to early referral to prehabilitation, which needs about four to six weeks to improve function. The decision to enroll patients in a prehabilitation program is based on the understanding of the needs to maintain a structured and personalized intervention taking into consideration the patient’s health status, the type of surgery, and the state of the disease. Perioperative evaluation and prehabilitation for older adults are evolving fields, which are generating clinical and scientific interest. This article will review relevant topics to help clinicians adapt usual perioperative care to older patients’ particular needs.

Published: August 2023

Background: Emotional and behavioural disorders are very common in childhood and adolescence. Homoeopathy is an alternative system of medicine which has a potential role in Child and Adolescent Psychiatry (CAP).
Objectives: To identify, summarize and disseminate research findings that could assess the role of Homoeopathy in CAP.
Materials and Methods: Two electronic databases PubMed and Google scholar are searched for publications on childhood behavioural disorders in peer-reviewed, indexed journals. Articles published on Homoeopathy and CAP in the past two decades i.e from 2000 to 2020 are included. An explicit systematic search strategy included web-based key word searches. The collected information has been collated, summarized, and the results are presented in tables and charts according to key themes.
Results: The research studies varied widely in all aspects such as design, conduct, intervention and outcome reporting. 38 eligible studies are identified on different clinical conditions in CAP. Individual sources of data are critically appraised and findings are discussed in terms of implications for gaps in research.
Conclusions: There is limited yet convincing evidence for usefulness of Homoeopathy in CAP disorders such as Autism and ADHD. Our review emphasises the paucity of studies in other CAP disorders such as Intellectual disability, Learning disability, Conduct disorder, Childhood depression and Anxiety disorders etc. which is the domain of future research.

Współczesne przedsiębiorstwo, które pragnie przetrwać w nieprzewidywalnych warunkach, postawione zostało przed koniecznością sprostania wyzwaniom płynącym z rynku i konkurencji. Powinno więc wykształcić trwałe atuty, które wyróżnią je na tle konkurencji, zadecydują o jego unikalności i pozwolą osiągnąć trwałą przewagę konkurencyjną przez długi okres. Przedsiębiorstwo musi więc przeprowadzić działania na rożnych obszarach funkcjonowania, czyli projektowania, produkcji, marketingu, sprzedaży, promocji i dystrybucji. Ponadto należy zwrócić uwagę na konieczność wypracowania atrybutów, które stanowią swoistą odpowiedź na pojawiające się bodźce płynące z otoczenia rynkowego. Niewątpliwie takim atrybutem jest zwinność pracownicza w organizacji.
Zwinność powinna być traktowana jako źródło przewagi konkurencyjnej, którą przedsiębiorstwo może wypracować za pomocą atrybutów zwinności zapewniających efektywne i błyskawiczne reagowanie na zmiany rynkowe i pojawiające się bodźce. Zatem warunkiem uzyskania ugruntowanej pozycji w świecie biznesu powinny być: elastyczna współpraca z otoczeniem, silna orientacja na klienta oraz zdolność do rekonfiguracji procesów biznesowych. Na rynku przetrwać może tylko przedsiębiorstwo zwinne, bystre, w pełni adaptujące się do nowych warunków otoczenia. Cechy zwinności przedsiębiorstwa, jego struktura sieciowa przyczyniają się w dużej mierze do uzyskania przewagi konkurencyjnej. Dzięki zwinności przedsiębiorstwa mogą skutecznie reagować na nieprzewidywalne zmiany.
