Insights on the Optical and Infrared Nature of MAXI J0709-159: Implications for High-Mass X-ray Binaries
In our previous study (Bhattacharyya et al., 2022), HD 54786, the optical counterpart of the MAXI J0709-159 system, was identified to be an evolved star, departing from the main sequence, based on comparisons with non-X-ray binary systems. In this paper, using color-magnitude diagram (CMD) analysis for High-Mass X-ray Binaries (HMXBs) and statistical t-tests, we found evidence supporting HD 54786s potential membership in both Be/X-ray binaries (BeXRBs) and supergiant X-ray binaries (SgXBs) populations of HMXBs. Hence, our study points towards dual optical characteristics of HD 54786, as an X-ray binary star and also belonging to a distinct evolutionary phase from BeXRB towards SgXB. Our further analysis suggests that MAXI J0709-159, associated with HD 54786, exhibits low-level activity during the current epoch and possesses a limited amount of circumstellar material. Although similarities with the previously studied BeXRB system LSI +61? 235 (Coe et al., 1994) are noted, continued monitoring and data collection are essential to fully comprehend the complexities of MAXI J0709-159 and its evolutionary trajectory within the realm of HMXBs. 2024 Societe Royale des Sciences de Liege.

Insinuating cocktailed components in biocompatible-nanoparticles could act as an impressive neo-adjuvant strategy to combat COVID-19
The novel Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) spread, freezes all sectors, and was declared as a life-threatening disease by the World Health Organization on Jan 30, 2020. So far, no specific drugs are identified or approved for treating SARS-CoV-2. In the past few years, nanomaterials are in the limelight for their ability to deliver the drugs effectively and selectively like siRNA to target/prime infection sites, and benefits us to visualize the particular regions, treatment reactions via non-intruding imaging techniques. As intranasal delivery interacts directly to the infection site with minimal side effects on the healthy cell, we postulate to administer a mixture of few polyherbal formulations like the golden spice curcumin, sitopaladi churna (SPC), and kaempferol in zein-chitosan nanoparticles as a life-saving measure for treating Coronavirus disease (COVID-19) cases. This viewpoint will shed light on the antiviral role of curcumin, SPC, and kaempferol zein-chitosan nanoparticle to modulate immune responses and observe its curative approach to the current pandemic COVID. 2021, Visagaa Publishing House.

Instabilities in ferrofluids with temperature and magnetic field dependent viscosity under different modulations
There has been a vigorous effort by researchers to study and characterize Rayleigh Be and#769;nard convection in ferrofluids owing to their interesting applications. From the survey of the literature pertinent to the problems under consideration in our study we realize the importance of using variable viscosity and thus explore the dynamics of a ferrofluid with temperature and magnetic field dependent viscosity which is in a Rayleigh- Be and#769;nard situation. The system under consideration is subjected to external constarints viz., an imposed time-periodic body force, rotation speed modulation, temperature modulation and magnetic field modulation. The problem considers both sinusoidal and non-sinusoidal time-periodic variations of these modulations to study the onset and post-onset regimes of Rayleigh-Be and#769;nard ferroconvection. We perform a weakly non-linear stability analysis using a truncated Fourier series representation and arrive at the Lorenz system for ferrofluid convection with variable viscosity. By using the linearized form of the Lorenz system we arrive at the critical Rayleigh There has been a vigorous effort by researchers to study and characterize Rayleigh Be and#769;nard convection in ferrofluids owing to their interesting applications.

Instigating the mixed phases of cobalt oxide in nanowires for electrolysis of urea-based water
The urea oxidation reaction (UOR) offers a more energy-efficient alternative to water splitting, with a lower theoretical potential of 0.37 V and the possibility of using urea-based wastewater as an electrolyte. In this study, phosphorus/boron-incorporated cobalt oxide nanowires supported on nickel foam (P,B-CoxOy NW@NF) are synthesized by hydrothermal and reduction methods as an electrocatalyst for UOR. The P,B-CoxOy NW@NF demonstrates exceptional electrocatalytic performance with a low UOR potential of 1.33 V at 50 mA/cm2 in alkaline media. Comprehensive structural and morphological analyses reveal the formation of mixed Co3O4-CoO phases with abundant oxygen vacancies (Ov) and Co2+ species, which synergistically enhance conductivity and provide ideal surroundings for active M?OOH species formation. In-situ electrochemical kinetic studies highlight the superior catalytic activity of P,B-CoxOy NW@NF, attributed to a high density of active sites, improved reactant adsorption, and efficient desorption of byproducts, including CO2. The catalyst exhibits excellent long-term stability with minimal degradation of 7 % over 100 h of continuous chronoamperometry testing and 2 % loss after 10,000 cycles. Furthermore, the activity of P,B-CoxOy NW@NF is evaluated in alkaline natural cow urine, requiring just 1.35 V at 50 mA/cm2 for UOR, demonstrating its practical relevance for real-world applications. These findings showcase the significant potential of P,B-CoxOy NW@NF as a scalable and stable electrocatalyst for sustainable hydrogen production from wastewater. 2025 Elsevier Ltd -

Insurance coverage framework for assisted reproductive treatments for women
Giving birth to a child is considered as one of the purest and highest forms of giving by any human being. The harsh reality is that not all men and women can reproduce. Some remain childless their entire life. Infertility hurts both men and women, but women more. Women continue to face social stigma of not bearing a child and go through stress, anxiety, and depression (Donkar, 2007; Widge, 2002; Reissman, 2000). One of the most significant contributions of Medical Science is the invention of Assisted Reproductive Technology Treatments that help infertile couples to conceive. India has been a pioneer in adapting to this technology and since 1978 many couples have been able to give birth to a child. Unfortunately, these treatments are expensive. Infact, the high treatment cost is the predominant source of anxiety in patients going through these treatments across the world (Iaconelli, 2013). There are instances where, couples leave the treatment, mid way as they are not able to arrange more money (Brennan et al., 2006). However, countries like Denmark, Canada, New Zealand, Belgium, and Japan, to name a few have included these treatments under their Government health insurance policy, whereas countries such as UK, USA, and Singapore have their Private Health insurance companies covering them. In comparison with its western counterparts, India is far behind in using Insurance as a method to finance Assisted Reproductive treatments. A preliminary study indicated two things- The resistance from the Insurance company's side in venturing into a product of this sort and secondly, unavailability of an insurance framework to guide them to venture into such a product. Thus, study began with the sole intention of creating an Insurance framework for assisted Reproductive Treatments particularly for women. A Qualitative Methodology has been adapted for the study. As a first step, infertility treatment polices from developed and developing countries were gathered and analyzed to extract the components of the drafting an Assisted re productive Treatment policy framework. Using these components, interview schedules were made to solicit information from the three different stakeholders. In-depth face to face interviews with 13 Doctors, 12 Patients, and 10 Insurers were conducted and data was further analyzed using Qualitative Content Analysis Method as prescribed by Olle Rudolf Holsti in 1968 and refined by Downe-Wamboltdt in 1992. The concepts of reduction, distillation, and condensation as prescribed by Olle Findahl in 1981, Stephen Cavanagh in 1997, and Paul Atkinknson in 1996 have been used. The results pave the way for the proposed framework. This framework can be used as a guide by Insurance companies in defining the disease, designing the value proposition, entry and exit age, coverage as per stage of treatment, designing the proposal form to solicit information from the insured, arriving at the sum Insured, drafting conditions and exclusions of the policy, pricing, and promotional aspects, mitigation of moral hazards and claims management. The framework suggests a model that can benefit patients to avail insurance at a nominal price. -

Insurance Data Analysis with COGNITO: An Auto Analysing and Storytelling Python Library
Data pre-processing has taken an enhanced role with the advent of Machine learning. It is a vital element that forms the encore of the data science and business analytics process. Data pre-processing involves generating descriptive statistical summary, data cleaning, and data manipulation based on inputs gained after the initial analysis. Of late, it has been observed that data science practitioners spend 45% to 50% of their time cleaning and processing the data. Much time can be saved if the data transformation process can be automated. The COGNITO framework helps in performing the automated feature engineering and data storytelling of the dataset based on end-user discretion. The present work discusses the process and results obtained when automated feature engineering was performed on an insurance dataset using COGNITO. 2021 IEEE. -

Integral Transforms andGeneralized Quotient Space ontheTorus
In this chapter, we discuss one of the recent generalization of Schwartz distributions that has significantly influenced the expansion of various mathematical disciplines. Here, we study the space of generalized quotient on the torus. Different integral transforms are investigated on the space of generalized quotients on the torus BS?(Td). The space BS?(Td) is made of both distributions as well as space of hyperfunctions on the torus. Further, by introducing the relation between the Fourier and other integral transforms, the conditional theorems are proved for generalized quotients on tours. Moreover, we study the convergence structure of delta-convergence on the generalized quotient space, and an inversion theorem is proved.

Integrated 3D-Printed Detector for Rapid Near-IR Turn-On Colorimetric and Fluorescent Detection of Phosgene
Phosgene is a widely used yet highly hazardous compound that poses serious risks to human health and public safety due to its potential for misuse and accidental release. Therefore, developing an accurate and highly sensitive detection method is of critical importance. In this work, we have synthesized a sulfo-cyanine-based dye (CyNH) for the selective rapid detection (<1 min) of phosgene by Near-IR turn-on colorimetric and fluorescence responses. Notably, CyNH exhibited a 3-fold fluorescence enhancement at 756 nm accompanied by a distinct color change from light blue to dark blue by the appearance of strong absorption signal at 600 nm, with a detection limit of 1.17 ?M. To enable on-site detection, a 3D-printed sensor of the CyNH-coated 3D-printed substrate was developed, which shows visible color changes upon exposure to phosgene. Furthermore, integration of this sensor with a smartphone camera and its processing capabilities allows for real-time quantification of phosgene concentrations by eliminating the need for costly analytical instruments. To the best of our knowledge, the development of an NIR probe enabling dual colorimetric and fluorescent NIR detection of phosgene using a 3D-printed sensor is scarcely reported. This innovative 3D-printed, smartphone-assisted sensing platform offers a practical and sustainable approach for future phosgene detection applications in various fields. 2026 American Chemical Society -

Integrated biogasification and carbon capture pathways: a system-level review of technologies, storage options, and deployment challenges
Carbon-negative energy systems that integrate bioenergy production with permanent carbon dioxide (CO2) sequestration are increasingly recognized as essential for achieving global net-zero and beyond-zero climate targets. While extensive research exists on individual components such as biogasification, carbon capture technologies, and geological storage, a coherent system-level synthesis linking these pathways remains fragmented. This review addresses this gap by providing an integrated assessment of biogasification-based carbon capture and storage (CCS) systems, with particular emphasis on techno-economic performance, capture efficiency, subsurface storage options, and deployment challenges. Following the PRISMA 2020 guidelines, 112 studies were systematically selected from an initial pool of 780 publications and analyzed to compare advanced gasification routes, emerging capture technologies, and storage strategies. The results indicate that hybrid gasificationsolid oxide fuel cell systems can achieve efficiencies of up to 55%, while cryogenic carbon capture consistently delivers CO? purities above 95% with reduced energy penalties. Supercritical water gasification and hydrothermal pathways demonstrate strong potential for wet biomass conversion, achieving hydrogen yields exceeding 1150 mmol/L and carbon efficiencies above 80%. Despite these technical advances, large-scale deployment remains constrained by high costs (USD 8001350 per tonne CO2), infrastructure limitations, and policy uncertainty.

Integrated biorefinery development for pomegranate peel: Prospects for the production of fuel, chemicals and bioactive molecules
Current experimental evidence has revealed that pomegranate peel is a significant source of essential bio compounds, and many of them can be transformed into valorized products. Pomegranate peel can also be used as feedstock to produce fuels and biochemicals. We herein review this pomegranate peel conversion technology and the prospective valorized product that can be synthesized from this frequently disposed fruit waste. The review also discusses its usage as a carbon substrate to synthesize bioactive compounds like phenolics, flavonoids and its use in enzyme biosynthesis. Based on reported experimental evidence, it is apparent that pomegranate peel has a large number of applications, and therefore, the development of an integrated biorefinery concept to use pomegranate peel will aid in effectively utilizing its significant advantages. The biorefinery method displays a promising approach for efficiently using pomegranate peel; nevertheless, further studies should be needed in this area. 2022 Elsevier Ltd -
Integrated Effect of Flow Field Misalignment and Gas Diffusion Layer Compression/Intrusion on High Temperature - Polymer Electrolyte Membrane Fuel Cell Performance
Misalignment in the flow field plates of High-Temperature Polymer Electrolyte Membrane Fuel Cell (HT-PEMFC) due to manufacturing tolerances, assembly process, or unavoidable vibration during the cell operation is contemplated its performance and durability. This study investigates the effect of flow field plate misalignment and its concomitant impact with varying the clamping pressures on HT-PEMFC operation. The study considers six degrees of cathode flow field misalignment, varying from 0% to 100% with respect to the anode flow field. Clamping pressures ranging from 1 to 2 MPa are applied to the various cases of misalignment to study their effect on GDL deformation and intrusion into the channels. The structural analysis shows that as the misalignment increases from 0 to 100%, the GDL compression increases from 26.72% to 37.75% for 1 MPa, 40.07% to 56.63% for 1.5 MPa, and 53.43% to 75.51% for 2 MPa, owing to the increase in compression approximately by 41% from their base cases and it is also crucial to note that GDL compression exaggerates at higher clamping pressures. The misalignment results in the sagging of Membrane Electrode Assembly (MEA), and the amplitude of wave nature is proportional to the degree of misalignment and clamping pressure, indicating the misalignment is the sole factor for structural changes. As a result, considerable variance in current distribution and average value is observed, i.e., at operating voltage 0.5 V, the current density drops from 4472.7 to 4264.4, 4420.7 to 4211.8, and 4374.1 to 4161.3 A m?2 from cases 1 to 6 for clamping pressures 1, 1.5, and 2 MPa, respectively, resulting in a 4.7% loss in performance. According to the observations, a misalignment of 60% is tolerable, with minimal performance loss and negligible non-uniformity in cell distributions. 2022 The Electrochemical Society (ECS).

Integrated Health Care Delivery and Telemedicine: Existing Legal Impediments in India
The technological innovation in the healthcare sector has contributed to the growth of telemedicine in India. Health services fall under State responsibility as per the Indian Constitution by virtue of Schedule 7although policy and planning framework are under the scope of Central government. Telemedicine cannot not work as an autonomous service, rather, ought to be subjected to different regulations having complex ethical, medico-legal manifestations. As far as India is concerned, Ministry of Health and Family Welfare of India (MoHFW) is the body responsible for initiating the policy of digitization of healthcare. However the point ishow far digital health services going appropriately in India. Based on NDHBs comprehensive architectural framework of Federated National Health Information System in January 2020 and as the pandemic strategy Medical Council of India and the NITI Aayog released new guidelines on telemedicine with respect to registered medical practitioners, this research needed to be checked. Thus, the examination was done in these aspects. Guidelines were revisited to see how the hospitals in Delhi and NOIDA function based on the records submitted in medical consultation given to patients using telemedicine. It is felt that telemedicine being a nebulous concept in India, it needs to be analyzed in the light of prospective opportunities it would offer. There is a need for collaborative approaches on digital health, revision in the prevailing legal and ethical frameworks, the clinical practices corresponding to standing medical guidelines. Also, it is found that there exist no uniform telemedicine practices balancing the privacy norms, medico-legal responsibility and regulatory standards. To arrive at conclusion, the best practices prevailed in other countries are examined and adopted. It is felt that the policies existing in telemedicine need to be bifurcated as digital consultation, digital photography, remote patient monitoring (RPM) separately. 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
