Power Allocation Strategies for Wireless Relay Networks with Analog Network Coding: Survey

Relay aided communication with network coding can bring spectacular performance enhancements for wireless networks. The proper design of power allocated to each of the nodes involved in the communication is essential as it has impact on the performance when Analog Network coding (ANC) is used. This paper presents a survey on recent power allocation strategies, intended objectives, practical constraints that have been considered, and corresponding performances for networks with ANC protocol

Generation and prioritization of test casesusing Simulink/Stateflow models

Embedded systems are mainly modeled by using MATLAB's simulink and stateflow tools. MATLAB's simulink is a tool for modeling, simulating and analysing software systems and stateflow is a control logic tool used to model event-driven systems (Reactive systems) through state machines and flow charts within a simulink model. In real-time, systems undergo frequent changes, thus complexity of the systems grows and testing of the systems become time consuming and expensive even if changes occur in small parts of the system. So, these models need formal verification. In this paper, we focus on event-driven systems which are captured by stateflow model. For this, we propose an algorithm (\textit{GenerateGraph}) in which we first generate an XML file for the stateflow model of a system. Then, we parse that XML file following top-down approach by using XML parser. Next, we generate intermediate graph for the model, using the parsed information. By using this graph, we generate test cases for the models of the systems having composite states

Indian perspective about COVID-19 vaccine: an elixir bringing ray of hope to the dark pandemic

India has finally begun its colossal coronavirus vaccine drive, desperately hoping to end a deadly pandemic that has killed around 1.5 lakh of its population. With an aim to vaccinate about 300 million people across the subcontinent by July, India has a huge task ahead. This large number roughly amounts to almost the entire US population

Predictors of Depression and Life Satisfaction Among Asian Indians Living in the United States of America

This study assessed the statistical contribution of gender, acculturation, Asian values, coping self-efficacy and discrimination in the prediction of depression and life satisfaction with Asian Indian American adults. The increasing number of Asian Indians in the United States has prompted psychologists and other clinicians to seek understanding of the unique mental health needs of this population. However, previous studies on predictors of depression and life satisfaction among Asian Indians living in the United States had been scarce and inconclusive. The current study, grounded in Berry’s multidimensional theory of acculturation, used a cross-sectional correlational survey design to examine if gender, acculturation, Asian values, coping self-efficacy and discrimination predict depression and life satisfaction. A sample of 138 Asian Indian American adults living in the United States of America participated in the study. Standard multiple linear regression analyses revealed coping self-efficacy as the only predictor of depression and life satisfaction. There were gender differences in depression, life satisfaction, Asian values, and coping-self efficacy with women scoring higher than men on depression, but lower on life satisfaction, coping self-efficacy, and Asian values. The study’s findings provide clinicians with critical knowledge on the role of self-efficacy in the prediction of depression and life satisfaction among Asian Indians. Results further suggest the potential for effecting positive social change through interventions focusing on the development of self-efficacy

Physical properties of Tolman-Bayin solutions: some cases of static charged fluid spheres in general relativity

In this article, Einstein-Maxwell space-time has been considered in connection to some of the astrophysical solutions as previously obtained by Tolman (1939) and Bayin (1978). The effect of inclusion of charge into these solutions has been investigated thoroughly and also the nature of fluid pressure and mass density throughout the sphere have been discussed. Mass-radius and mass-charge relations have been derived for various cases of the charged matter distribution. Two cases are obtained where perfect fluid with positive pressures give rise to electromagnetic mass models such that gravitational mass is of purely electromagnetic origin.Comment: 15 pages, 12 figure

Titania coated silica nanocomposite prepared via encapsulation method for the degradation of Safranin-O dye from aqueous solution: Optimization using statistical design

AbstractTitania coated silica nanoparticles, which were synthesized via nanoparticle encapsulation route, are employed to degrade safranin-O dye from aqueous solution under UV light irradiation and were characterized by FT-IR, XRD, FESEM, N2 adsorption-desorption method and Zeta potential measurement. The results showed that the nanoparticles have a core-shell structure composed of about 100nm of diameter of silica with several TiO2 fine particles in shell. After the degradation, this process is optimized through the response surface methodology (RSM). In this response study, photodegradation efficiency was evaluated by three main independent parameters such as catalyst dose, initial dye concentration and reaction time. Parameter sensitivity studies of the degradation efficiency of titania coated silica nanoparticles have shown 93.29% degraded under the optimal conditions of catalyst dose of 89.80mg/g, initial dye concentration of 17.61mg/L and reaction time of 12min. We cross-checked the predicted values of degradation efficiency with the experimental values and were found to be in good agreement (R2=0.9983 and adj-R2=0.9967)

Efficacy of single dose of misoprostol 800μg in the first trimester termination of pregnancy: a cross sectional study

Background: The MTP (Amendment) Act 2021 has allowed termination of pregnancy up to 24 weeks on only certain indications. Decision of two medical practitioners are required for termination beyond 20 weeks. Misoprostol is one drug used for medical termination of pregnancy. It can be used alone in single or multiple doses, or in combination with other drugs. The study was undertaken to determine the efficacy of a single dose of 800 μg of misoprostol in the first trimester pregnancy termination. Methods: It was a cross-sectional study conducted among 124 women in the first trimester who were undergoing termination of pregnancy. After administering 800 μg of misoprostol vaginally, participants were kept under observation for 48 hours. Data were collected and analysed. Results: Around half of the participants (56.4%) expelled the conceptus completely by 12 hours, 78.2% by 48 hours. Seven (5.6%) out of those 27 failed cases were given further doses of misoprostol, while in the remaining 20 (16.1%), surgical intervention was undertaken. Conclusions: The efficacy of a single dose of misoprostol for 1st trimester termination of pregnancy varies widely from study to study, but, the efficacy increases with adding further doses of the same drug or addition of mifepristone. Misoprostol is a safe, cost effective, and reasonable drug for the termination of pregnancy in first trimester
