We examine security analysts’career concerns by relating their earnings forecasts to job separations. Relatively accurate forecasters are more likely to experience favorable career outcomes like moving up to a high-status brokerage house. Controlling for accuracy, analysts who are optimistic relative to the consensus are more likely to experience favorable job separations. For analysts who cove...

We study the role neutrino telescopes could play in discovering supersymmetric extensions of the Standard Model with a long-lived stau next-to-lightest superparticle. In such a setup, pairs of staus are produced by cosmic neutrino interactions in the Earth matter. In optimistic scenarios, one can expect several pair events per year in a cubic kilometer detector such as IceCube. We also show tha...

We introduce the novel notion of Verifiable Encryption of Chameleon Signatures (VECS), and then use it to design a three-round abuse-free optimistic contract signing protocol.

India, mainly powered by coal, has adopted ambitious renewable energy targets and currently considers a climate neutrality target for 2050. The rapid growth of solar PV power faces challenges due to its variable generation resulting in decline economic value. In this paper, we evaluate the potential battery storage stabilize market value three scenarios further costs decrease. We estimate optim...

determining the optimal pattern for growing crops in accordance with the availability of the resources and risk factors as well as the uncertainty of agriculture sector would help the farmers, managers and economic planners in selecting the type of the product and the level of cultivation. fuzzy programming model with interval programming approach is used in this study to determine the optimal ...

We propose a tightening sequence of optimistic approximations to the Gittins index in “Optimistic Indices.” show that use these concert with an increasing discount factor appears offer compelling alternative state-of-the-art schemes proposed for Bayesian multiarmed bandit problem. prove indices constitutes regret optimal algorithm. Perhaps more interestingly, even loosest substantial performanc...

background studies show that a large proportion of healthcare offered may be inappropriate or unnecessary. magnetic resonance imaging (mri) is a new and expensive diagnostic technology which has been increasingly used all over the world. moreover, this trend has been more rapidly increasing in iran. low back pain is a common disorder all over the world and mri technique is one of the several wa...
