1 Electronics and Telecommunication, Pune University Cognitive Radio technology helps in designing wireless system for efficient deployment of radio spectrum with its sensing technique,self adaptation and spectrum sharing. Spectrum sharing is an effective method of alleviating the scarcity of radio spectrum problem by allowing unlicensed users (secondary users) to coexist with licensed users (p...

BACKGROUND Increased knowledge of the harmful effects of SHS is an evidence-based key indicator for eliminating nonsmokers' exposure to SHS. This study assessed the prevalence and predictors of perceptions about the harm of secondhand smoke (SHS) exposure among U.S. middle and high school students. FINDINGS Data were obtained from the 2012 National Youth Tobacco Survey, a nationally represent...

This issue of PLoS Genetics contains the second of two important papers describing the high levels of meiotic failure caused by exposure of female mice to a chemical known as Bisphenol A (BPA) [1]. In the first article [2], Pat Hunt and her collaborators demonstrated high levels of meiotic failure in females exposed to BPA, suggesting that BPA exposure affects maturing oocytes. This conclusion ...

We construct an infinite horizon model of harmful addiction. Consumption is compulsive if it differs from what the individual would have chosen had commitment been available. A good is addictive if its consumption leads to more compulsive consumption of the same good. We analyze the welfare implications of drug policies and find that taxes on drugs decrease welfare while prohibitive policies ma...

At this time, when we have still some months to wait for the findings of the Royal Commission, it may be of interest to consider the certification of the lunatic. It is unfortunate that on this point (as on others) there is still a conflict between the ideas of the doctor?interested solely in the ultimate as well as the immediate mental and physical welfare of the patient?and various people int...

Cognitive Radio technology helps in designing wireless system for efficient deployment of radio spectrum with its sensing technique, self-adaptation and spectrum sharing. Spectrum sharing is an effective method of alleviating the scarcity of radio spectrum problem by allowing unlicensed users(secondary users) to coexist with licensed users (primary users) under the condition of protecting the l...

The present paper aims to review current evidence for the effectiveness and/or feasibility of using inter-agency data sharing of ED recorded assault information to direct interventions reducing alcohol-related or nightlife assaults, injury or violence. Potential data-sharing partners involve police, local council, liquor licensing regulators and venue management. A systematic review of the peer...

AIMS Teenagers in the UK report some of the highest rates of alcohol use in Europe. We identify patterns of alcohol use in early adolescence and relate these to hazardous and harmful alcohol use at age 16. METHODS In a UK birth cohort, we analysed repeated measures of alcohol use from age 13 to 15 in a sample of 7100 adolescents. Data on drinking frequency and typical consumption when drinkin...
