An adaptive threshold element is able to "learn" a strategy of play for the game blackjack (twenty-one) with a performance close to that of the Thorp optimal strategy although the adaptive system has no prior knowledge of the game and of the objective of play. After each winning game the decisions of the adaptive system are "rewarded." After each losing game the decisions are "punished." Reward...

This paper studies the optimal joint design of disability insurance and unemployment insurance in an environment with moral hazard, when health status is private information, and cyclical fluctuations. I show how disability benefits and unemployment benefits vary with aggregate economic conditions in an optimal contract. In a special case of the model, I first show the optimal contract can be s...

hearing loss (hl) is the most common sensory defect. various genetic as well as environmental factors have been shown to contribute in it. more than 100 loci have been recognized to cause autosomal recessive nonsyndromic hearing loss (arnshl). here, we report a 6-year old female patient with bilateral pre-lingual hl in whom a mutation has been identified in triobp gene (c.6362c>t, s2121l). in s...

Increasingly, information systems rely on computational, storage, and network resources deployed in third-party facilities such as cloud centers edge nodes. Such an approach further exacerbates cybersecurity concerns constantly raised by numerous incidents of security privacy attacks resulting data leakage identity theft, among others. These have, turn, forced the creation stricter privacy-rela...
