Cell-Phone Use and Self-Reported Hypertension: National Health Interview Survey 2008

Background. Cell-phone usage has increased dramatically over the last decade, along with a rising public concern over the health effects of using this device. The association between cell-phone usage and hypertension has not been examined before. Methods. We analysed data from 21,135 adults aged ≥18 years who participated in the 2008 National Health Interview Survey. Based on reported cell-phone use, participants were categorized as cell-phone nonusers, predominantly landline users, dual users of cell phone and landline, and predominantly cell-phone users. The main outcome of interest was self-reported physician-diagnosed hypertension (n = 6,793). Results. 43.5% of the participants were cell-phone nonusers, while 13.8% were predominantly cell-phone users. We found that cell-phone use was inversely associated with hypertension, independent of age, sex, race/ethnicity, smoking, alcohol consumption, education, body mass index (BMI), and physical activity. Compared to cell-phone nonusers, the multivariable odds ratio (95% confidence interval) of hypertension was 0.86 (0.75–0.98, P trend  =  .005) among predominantly cell-phone users. This inverse association between cell-phone use and hypertension was stronger in women, those aged <60 years, whites, and those with BMI <25 kg/m2. Conclusion. We found that cell-phone usage was protectively associated with self-reported hypertension in a nationally representative sample of US adults

Temporal fluctuations of siachen glacier velocity: a repeat pass sar interferometry based approach

Glacier velocity, the glacier's health indicator, is an emerging research interest in global warming among the scientific community over the current decade. As per scientific reports, due to their stable and advanced nature, the glaciers of Karakoram are exclusive. The present study focuses on understanding the temporal velocity variability of the Siachen Glacier, Shyok Basin, Karakoram using SAR datasets, in the perspective of the difficulties in estimating the glacier velocity over the inaccessible Karakoram Mountain. For the hydrological year 2017-18, 30 sentinel-1 derived interferograms using the DInSAR technique were analyzed to obtain Line Of Sight velocity. The transient velocity of the glacier reflects separate patterns within the glacier for different seasons due to the thermodynamic and orographic system over the glacier surface. In azimuth and range direction, the projected annual LOS velocity to a two-dimensional surface velocity is estimated to be around 103.8 ± 3.1 m/year

Evaluating the usefulness of 50 millesimal potencies in the treatment of chronic diseases - A retrospective study

Introduction: The 50 millesimal potency, is not fully utilized in our day to day practice. This retrospective study was done to reveal a new horizon for the physicians who use it occasionally and an eye opener for those who have never tried it. Aim: The aim was to evaluate the usefulness of 50 Millesimal potency of indicated medicine in the treatment of chronic diseases from a retrospective study. Materials and Methods: Cases treated with 50 Millesimal potency (LM) during January-May 2014, were screened and based on eligibility criteria, 50 cases were selected to study retrospectively. Treatment outcome was analyzed based on follow-up criteria. Data were statistically analyzed with Chi-square test in GNU PSPP Software. Results: 50 Millesimal potencies have the potential to give significant improvement (P = 0.01) in the treatment of chronic diseases. There were no cases reported with aggravation. The action of LM potency is not influenced (P = 0.97) by previously used Centesimal potency. Constitutional prescription has proved to have significant (P = 0.01) association with treatment outcome with LM potency, whereas Sector prescription (P = 0.12) does not. Irrespective of age, gender, and duration of illness, 50 Millesimal potencies act advantageously. Conclusion: The data suggest that 50 Millesimal potencies have significant beneficial effects in the treatment of chronic diseases

Major Advances in Particle Swarm Optimization: Theory, Analysis, and Application

Over the ages, nature has constantly been a rich source of inspiration for science, with much still to discover about and learn from. Swarm Intelligence (SI), a major branch of artificial intelligence, was rendered to model the collective behavior of social swarms in nature. Ultimately, Particle Swarm Optimization algorithm (PSO) is arguably one of the most popular SI paradigms. Over the past two decades, PSO has been applied successfully, with good return as well, in a wide variety of fields of science and technology with a wider range of complex optimization problems, thereby occupying a prominent position in the optimization field. However, through in-depth studies, a number of problems with the algorithm have been detected and identified; e.g., issues regarding convergence, diversity, and stability. Consequently, since its birth in the mid-1990s, PSO has witnessed a myriad of enhancements, extensions, and variants in various aspects of the algorithm, specifically after the twentieth century, and the related research has therefore now reached an impressive state. In this paper, a rigorous yet systematic review is presented to organize and summarize the information on the PSO algorithm and the developments and trends of its most basic as well as of some of the very notable implementations that have been introduced recently, bearing in mind the coverage of paradigm, theory, hybridization, parallelization, complex optimization, and the diverse applications of the algorithm, making it more accessible. Ease for researchers to determine which PSO variant is currently best suited or to be invented for a given optimization problem or application. This up-to-date review also highlights the current pressing issues and intriguing open challenges haunting PSO, prompting scholars and researchers to conduct further research both on the theory and application of the algorithm in the forthcoming years
