In scenarios with a gravitino LSP, there exist strong BBN constraints on the abundance of a possible stau NLSP. We find that in settings with substantial leftright mixing of the stau mass eigenstates these constraints can be evaded even for very long-lived staus.

We discuss how Dirac neutrinos can naturally be generated in supersymmetry and how they allow for an Affleck-Dine leptogenesis scenario, in which a leftright asymmetry is generated in the sneutrino sector, the left part of which is transferred to a baryon asymmetry via sphaleron transitions. No exotic fields need to be added to the MSSM other than the right-handed neutrino.

In this paper we study the steady state availability of main k-out-of-n: F and secondary subsystems having general repair time distribution. When more than k units of main subsystem fail, then the main subsystem shuts off the secondary subsystem. The life time distributions of the main units and that of secondary subsystem are exponentially distributed. A repair facility having single repairman...

The present study attempts to analyze Iraq war against Iran based on Parsons' subsystems. The main question aims at finding the social positive/negative functions of the war. According to the studies, the first effect of the war was damaging behavioral organism subsystem so that it couldn't realize its functions. Subsequently, the chaos spread to the personality subsystem. Except for the qualit...

The interest, the status and the perspectives of various experiments in neutron and nuclear beta-decay, muon-decay and pion-decays are discussed. The talk is segmented into a discussion of the decay-rates and of the energy-spectra and correlations. The impact on various scenarios of ”new physics” is briefly mentioned ; leftright symmetric models are discussed in more detail and the informations...

I consider an argument, due to Geoffrey Lee, that we can know a priori from the leftright asymmetrical character of experience that our brains are left-right asymmetrical. Lee’s argument assumes a premise he calls relationism, which I show is well-supported by the best philosophical picture of spacetime. I explain why Lee’s relationism is compatible with left-right asymmetrical laws. I then sho...

in this paper we have proposed an approach for emotion detection in implicit texts. we have introduced a combinational system based on three subsystems. each one analyzes input data from a different aspect and produces an emotion label as output. the first subsystem is a machine learning method. the second one is a statistical approach based on vector space model (vsm) and the last one is a key...
