PIONEER is a next-generation experiment to measure the charged pion branching ratios electrons vs. muons Re/?=??+?e+?(?)??+??+?(?) and beta decay (Pib) ?+??0e?. The muon (????e) has four orders of magnitude higher probability than electron (??e?). To achieve necessary branching-ratio precision it crucial suppress ????e energy spectrum that overlaps with low tail ??e?. A high granularity active ...

By Rami Atar, Amarjit Budhiraja and Paul Dupuis Technion-Israel Institute of Technology, University of North Carolina at Chapel Hill and Brown University Let G ⊂ IRk be a convex polyhedral cone with vertex at the origin given as the intersection of half spaces {Gi, i = 1, · · · , N}, where ni and di denote the inward normal and direction of constraint associated with Gi, respectively. Stability...

We study a model in which a "statistician" takes an action on behalf of an agent, based on a random sample involving other people. The statistician follows a penalized regression procedure: the action that he takes is the dependent variable’s estimated value given the agent’s disclosed personal characteristics. We ask the following question: Is truth-telling an optimal disclosure strategy for t...

This paper presents a novel 3D thermal simulation tool for semiconductor integrated devices. The simulator is used to automatically generate an accurate 3D physical model of the device to be simulated from layout information. The simulator produces an appropriate mesh of the device based on a rectangular block structure. The mesh is automatically created such that a fine mesh is produced around...
