All of the actinides and roughly half the natural abundance of elements with mass number A > 70 come from the rapid neutron capture process, or the r-process. If the r-process, as suggested by many, occurs deep in a supernova, then it is under the influence of an intense neutrino flux. Here we discuss the effects of both chargedcurrent and neutral-current neutrino interactions on the r-process....

Fixed-point logic with rank (FPR) is an extension of fixed-point counting (FPC) operators for computing the a matrix over finit field. The expressive power FPR properly extends that FPC and contained in P, but it not known if containment proper. We give circuit characterization terms families symmetric circuits gates, along lines given by Anderson Dawar 2017. This requires development broad fra...

the nonlinear discrete crack modeling of Shahid Rajaee thin arch dam is considered. The interface elements are positioned such that certain potential separated blocks can form possible failure mechanisms. The dynamic stability of theses blocks are investigated by a special finite element program "MAP-73" which its nonlinear algorithm and interface elements formulation are presented.

Feature modeling is an important approach to dealing with variability at an abstract level in a hierarchical manner extensively used in software product lines. For its use in conjunction with other UML models and MDA approach, it is important to correctly integrate feature modeling into UML. In this paper, we present an approach to integrating feature modeling into UML that respects abstractnes...

A bstract. T he periodic behavior of a particu lar class of dynamical sys tems , the cellular automata (CA) , is studied . A lar ge class of CAs is defined , (containing both addit ive and nonadditive CAs) in terms of the sensi tivity of t he local rule on which the CA is based . For this class , the set of configurations which ente r a cycle afte r a finit e number of it erat ions is complete ...
