I review the ways that have been proposed to measure the quark transversity distribution in the nucleon. I then explain a proposal, developed by Xuemin Jin, Jian Tang and myself, to measure transversity through the final state interaction between two mesons (ππ, KK, or πK) produced in the current fragmentation region in deep inelastic scattering on a transversely polarized nucleon.

Based on the fact the manipulation of fine nanoclusters calls for more precise modeling, the aim of this paper is to conduct an atomistic investigation for interaction analysis of particle-substrate system for pushing and positioning purposes. In the present research, 2D molecular dynamics simulations have been used to investigate such behaviors. Performing the planar simulations can provide a ...

Solutions for agreement problems in distributed sys tems can generally be divided into two classes authen ticated protocols and non authenticated protocols Au thenticated protocols make use of authenticated mes sages i e the messages can be signed in a way that a signed message can be assigned unambiguously to the signer Few has been said about how to achieve this kind of authentication in some...

abstract background: the parents of autistic children suffer from anxiety and tension. unawareness of parenting skills required for autistic children (parenting) doubles their anxiety. researchers have recently considered research on mobile education, especially mobile text messages. the present study aimed to investigate the effect of mobile parenting skills education on the anxiety of mothers...

abstract there are varieties of researches for appraisal of results obtained by countries in olympics, using data envelopment analysis method. this research is aimed to make such appraisal for iranians’ results in olympics games using the dea method. before taking any measures, main issues of dea methods for appraisal of olympics games in the previous research were discussed, afterward optimiza...
