Smoot, Tonya M., Xu, Ping, Hilsenrath, Peter, Kuppersmith, Nancy C., Singh, Karan P.
We assessed the prevalence of gastric bypass surgeries in the United States on the basis of data from the 1998 to 2002 National Hospital Discharge Survey. Between 1998 and 2002, rates (per 100 000...

The ubiquitination of the receptor that mediates signaling induced by the polypeptide pituitary hormone prolactin (PRL) has been shown to lead to the degradation of this receptor and to the ensuing...
Laurent-Gengoux Twisted K-theory of differentiable stacks
Jean-louis Tu, Ping Xu, Camille Laurent-gengoux
ABSTRACT. – In this paper, we develop twisted K-theory for stacks, where the twisted class is given by an S 1-gerbe over the stack. General properties, including the Mayer–Vietoris property, Bott...

Drought is one of the most important environmental constraints limiting plant growth and agricultural productivity. To understand the underlying mechanism of drought tolerance and to identify genes...
Acetoin Catabolism and Acetylbutanediol Formation by Bacillus pumilus in a Chemically Defined Medium
Distribution modeling and simulation of gene expression data
Parrish, Rudolph S., Spencer III, Horace J., Xu, Ping
Data derived from gene expression microarrays often are used for purposes of classification and discovery. Many methods have been proposed for accomplishing these and related aims, however the...
Xu, Ping, Brock, Guy N., Parrish, Rudolph S.
Linear discriminant analysis (LDA) is one of the most popular methods of classification. For high-dimensional microarray data classification, due to the small number of samples and large number of...

The objective of this study was to locate chromosomes for improving water and phosphorus-deficiency tolerance of wheat at the seedling stage. A set of Chinese Spring-Egyptian Red wheat substitution...
The level of Hsp27 in lymphocytes is negatively associated with a higher risk of lung cancer
Wang, Feng, Feng, Maohui, Xu, Ping, Xiao, Han, Niu, Piye, Yang, Xiaobo, ...
Heat shock proteins (Hsps) can protect cells, organs, and whole organisms against damage caused by abnormal environmental hazards. Some studies have reported that lymphocyte Hsps may serve as...
