Spin Hall effects are a collection of phenomena, resulting from spin-orbit coupling, in which an electrical current flowing through a sample can lead to spin transport in a perpendicular direction and spin accumulation at lateral boundaries. These effects, which do not require an applied magnetic field, can originate in a variety of intrinsic and extrinsic spin-orbit coupling mechanisms and dep...

Purdue University and Texas A&M University Consider M-estimation in a semiparametric model that is characterized by a Euclidean parameter of interest and a nuisance function parameter. We show that, under general conditions, the bootstrap is asymptotically consistent in estimating the distribution of the Mestimate of Euclidean parameter; that is, the bootstrap distribution asymptotically imitat...

A digraph D = (V,A) is mediated if for each pair x, y of distinct vertices of D, either xy ∈ A or yx ∈ A or there is a vertex z such that both xz, yz ∈ A. For a digraph D, ∆−(D) is the maximum in-degree of a vertex in D. The nth mediation number μ(n) is the minimum of ∆−(D) over all mediated digraphs on n vertices. Mediated digraphs and μ(n) are of interest in the study of quantum nonlocality. ...

We give some evidence that the worldvolume theory of the M-theory KK 6-brane is governed by a non-critical membrane theory. We use this theory to give a matrix description of Mtheory on T .

Humidity and C n data collected from the Chesapeake Bay area during the 2003/2004 period have been analyzed. We demonstrate that there is an unequivocal correlation between the data during the same time periods, in the absence of solar insolation. This correlation manifests itself as an inverse relationship. We suggest that C n in the infrared region is also function of humidity, in addition to...

Ginkgolides are key pharmaceutical components in Ginkgo biloba. Using the cDNA sequence of the MECP and MECT genes to design primers, we obtained the promoters of these genes from Ginkgo genomic DNA using the genome walking method. The two promoters were 744 and 982 bp in length, respectively. The cis-elements of the GbMECPs and GbMECT promoters were predicted and analyzed using the plant cis-a...
