the effects of including incoherent (bound-electron) and coherent (rayleigh) scattering in exposure buildup factor calculations for point isotropic gamma ray sources, penetrating a two-layer water-lead shield have been investigated in the gamma ray energy (e?) range of 40 kev to 3 mev. incoherent scattering decreases the values of these factors in both layers up to e? ~ 200 kev and the effect i...

We examine dijet production at large rapidity intervals at Tevatron energies, by using the theory of Lipatov and collaborators which resums the leading powers of the rapidity interval. We analyze the growth of the Mueller-Navelet K-factor in this context and nd it to be negligible. However, we do nd a considerable enhancement of jet production at large transverse momenta. In addition, we show t...

The various proposals for FQHE quasi-electron trial wave functions are reconsidered. In a short-range model for the electronic interaction, the energy expectation values of four different trial wave functions are calculated at filling factor 1 3 for up to ten electrons in the disk geometry. Jain's trial wave function displays the lowest energy expectation value.

The rapid accumulation of microarray data translates into a need for methods to effectively integrate data generated with different platforms. Here we introduce an approach, 2nd-order expression analysis, that addresses this challenge by first extracting expression patterns as meta-information from each data set (1st-order expression analysis) and then analyzing them across multiple data sets. ...

Given the importance of cultivating users’ positive behaviors in cyberspace, this study presents a comprehensive vision of how to address important virtues that might foster Taiwanese adolescents’ positive behaviors in cyberspace. In this study, we constructed an instrument—the Cyber Virtues Scale (CVS)—for measuring the underlying dimensions of Taiwanese adolescents’ virtuous behaviors in onli...

A relativistic quark model and a new set of wave functions of nucleon and ∆ have been used to study the electromagnetic properties of 12 + baryons and photoelectric production of ∆(1236). Theoretical results of GpM (q 2), μp, μΛ, μpG p E(q )/GpM (q 2), GE(q 2), and GM1+(q 2), μ, E1+, S1+ of p → ∆ are presented.
