Extended Apriori for association rule mining: Diminution based utility weightage measuring approach

The field of Association rule mining is a dynamic area for innovation of knowledge through which uncountable procedures have been expounded. Recently, by including significant components viz. value (utility), volume of items (weight) etc, the researchers have enhanced the quality of association rule mining for industry by bringing out the association designs. In this note, a proficient methodology has been put forward based on weight factor and utility for effective digging out of important association rules. At the very beginning, a traditional Apriori algorithm has been utilized that make use of the anti-monotone property which states that if n items are recurring continuously then n-1 items should also recur by which the scores of weightage(W-Gain), utility(U-Gain) and diminution(D-sum), are derived at. Eventually, we derive a subset of important association rules through which EUW-Score is generated. The tentative outcome demonstrates the effectiveness of the methodology in generating high utility association rules that is profitably used for the business improvement

EFFECT OF VARIABLE CANT ANGLE ON SWEEPBACK WING

Winglets are commonly used drag-reduction and fuel-saving technologies in today’s aviation. The primary purpose of the winglets is to reduce the lift-induced drag, therefore improving fuel efficiency and aircraft performance. Traditional winglets are designed as fixed devices attached at the tips of the wings. However, because they are fixed surfaces, they give their best lift-induced drag reduction at a single design point. In this work, we propose the use of variable cant angle winglets which could potentially allow aircraft to get the best all-around performance (in terms of lift-induced drag reduction), at different angle-of-attack values. This paper describes a XFLR 3-dimensional winglets analysis that was performed on a wing of NACA2412 cross sectional airfoil. The wing has span 2.40 m, root chord 0.180 m, tip chord 0.110 m, sweep angle 5 degree and taper ratio 0.556 and for a winglet NACA 0024 cross-sectional airfoil was considered of max thickness 24 percent at 30 percent chord, max camber 0 percent at 0 percent chord. The present study shows effects of wing without winglet, wing with winglet at cant angle 30, 60, 90. The results obtained from the analysis demonstrate that by carefully adjusting the cant angle, the aerodynamic performance can be improved

Serious adverse events and fatal outcomes following COVID-19 vaccination in the UK: lessons for other countries

Vaccines have taken the centre stage in the fight against COVID-19 pandemic, and in reducing hospitalisation and associated mortality. Countries around the world are heavily dependent on the successful rollout of their vaccination programmes to open up the societies and re-start their economies. However, the success of any vaccine programme, to a large extent, depends upon the efficacy and safety of the vaccines. Given that UK has been way ahead in vaccinating its population, is considered a successful model compared to other countries in Europe and elsewhere and has a yellow card reporting system for adverse events, we use UK as an example to understand the side effects and fatal outcomes following vaccinations. Our results show that AstraZeneca seems to be underperforming in terms of overall reporting of minor adverse events, serious incidents and fatal outcomes following vaccination. The risk of serious anaphylactic reaction and fatal outcome was 1.36 and 1.17 times more in case of AstraZeneca vaccine when compared with Pfizer BioNTech vaccine. The analysis has implications for vaccine policies and programmes both at nation-state and global levels

Doctors on duty: the real-life heroes during pandemic: Your opinion matters!!!

Background: Data for front-line health-care workers, risk of disease is limited so as the resources available. Although inspiring stories on doctors fighting against COVID-19-19 were covered we are still unaware of the challenges at ground level. The present study throws light on it and provides way through towards resolving the issues. Objectives:1. To assess the perceptions of the doctors towards the process of COVID-19-19 crisis management. 2.To identify the challenges and recommend solutions based on their views, suggestions. Methods: A cross sectional study on perception of doctors (94) involved in COVID-19 duty was conducted during July to September 2020, with the help of pre-validated semi-structured questionnaire through online google survey form. The questionnaire had demographic details, views on before, during and after the COVID-19 duty along with 4 open ended questions on their good and bad experiences, problems & suggestions. Descriptive statistics for quantitative & thematic analysis for qualitative data was used. Results: Nonresponse rate was 26%, mean age 27.55 year. Majority were from clinical departments (78%). 42% felt that training was proper, 60% adequate PPE kit, 52.6% were aware of management strategy, 86% stressed,82% found difficulties in communication. 42% were provided proper quarantine facility yet, 58% faced discrimination. Few themes emerged under challenges like lack of resources & training, stress & burnout, for which patient sensitization, refresher training, psychological & administrative support was suggested. Conclusion: Although COVID-19 pandemic has impacted life of doctors in either way, the challenges could easily be tackled by the recommended simple solutions

Pharmaceutico-Analytical Study of Chandrahasa Rasa - A Unique Formulation

Ayurveda is one of the oldest systems of medicine, is momentous in audience of worldwide on virtue of its holistic approach of life. Rasaushadhis in Ayurveda have a wide range of therapeutic utility due to their prolonged shelf life, finer particles size, being tasteless, odourless, minimum dose, quick action, makes them more effective and unique. With proper anupana, herbo-mineral formulations act effectively in a variety of pathological conditions. Jwara is considered as Rogadhipati i.e., most serious and king of all diseases in which the mind, sense organs and the body all are affected (Dehendriya mana santapakara). Chandrahasa Rasa (CR) is an unique herbo mineral Kharaliya Rasayana mentioned in Vaidya Chintamani of 16thAD constituting 14 ingredients with 5 bhavana dravyas which is solely indicated in Ashta vidha Jwara and 13 Sannipataja Jwara.

Human Skin, Oral, and Gut Microbiomes Predict Chronological Age.

Human gut microbiomes are known to change with age, yet the relative value of human microbiomes across the body as predictors of age, and prediction robustness across populations is unknown. In this study, we tested the ability of the oral, gut, and skin (hand and forehead) microbiomes to predict age in adults using random forest regression on data combined from multiple publicly available studies, evaluating the models in each cohort individually. Intriguingly, the skin microbiome provides the best prediction of age (mean ± standard deviation, 3.8 ± 0.45 years, versus 4.5 ± 0.14 years for the oral microbiome and 11.5 ± 0.12 years for the gut microbiome). This also agrees with forensic studies showing that the skin microbiome predicts postmortem interval better than microbiomes from other body sites. Age prediction models constructed from the hand microbiome generalized to the forehead and vice versa, across cohorts, and results from the gut microbiome generalized across multiple cohorts (United States, United Kingdom, and China). Interestingly, taxa enriched in young individuals (18 to 30 years) tend to be more abundant and more prevalent than taxa enriched in elderly individuals (>60 yrs), suggesting a model in which physiological aging occurs concomitantly with the loss of key taxa over a lifetime, enabling potential microbiome-targeted therapeutic strategies to prevent aging.IMPORTANCE Considerable evidence suggests that the gut microbiome changes with age or even accelerates aging in adults. Whether the age-related changes in the gut microbiome are more or less prominent than those for other body sites and whether predictions can be made about a person's age from a microbiome sample remain unknown. We therefore combined several large studies from different countries to determine which body site's microbiome could most accurately predict age. We found that the skin was the best, on average yielding predictions within 4 years of chronological age. This study sets the stage for future research on the role of the microbiome in accelerating or decelerating the aging process and in the susceptibility for age-related diseases
