BACKGROUND Estimating the number of genes in human genome has been long an important problem in computational biology. With the new conception of considering human as a super-organism, it is also interesting to estimate the number of genes in this human super-organism. PRINCIPAL FINDINGS We presented our estimation of gene numbers in the human gut(More)
— Technologies for fabricating silicone rubber membranes and integrating them with other processes on silicon wafers have been developed. Silicone rubber has been found to have exceptional mechanical properties including low mod-ulus, high elongation, and good sealing. Thermopneumatically actuated, normally open, silicone rubber membrane valves with(More)
The Grid middleware must be developed iteratively and incrementally, so Grid performance testing is critical for middleware developers of Grid system. Considering the special characters of Grid system, in order to gain meaningful and comprehensive results of performance testing, it is necessary to implement testing on real Grid environment with various(More)
Sl NAC1 functions as a stress-responsive NAC protein involved in the abscisic acid-dependent signaling pathway and enhances transgenic Arabidopsis drought, salt, and cold stress tolerance. NAC (NAM, ATAF1, 2, CUC2) transcription factors constitute the largest families of plant-specific transcription factors, known to be involved in various growth or(More)
HTm4 (MS4A3) is a member of a family of four-transmembrane proteins designated MS4A. MS4A proteins fulfil diverse functions, acting as cell surface signalling molecules and intracellular adapter proteins. Early reports demonstrated that HTm4 is largely restricted to the haematopoietic lineage, and is involved in cell cycle control, via a regulatory(More)
Biometrics authenticated schemes using smart cards have attracted much attention in multi-server environments. Several schemes of this type where proposed in the past. However, many of them were found to have some design flaws. This paper concentrates on the security weaknesses of the three-factor authentication scheme by Mishra et al. After careful(More)

OBJECTIVE We assessed HIV/AIDS expenditures in Dehong Prefecture, Yunnan Province, one of the highest prevalence regions in China, and describe funding sources and spending for different categories of HIV-related interventions and at-risk populations. METHODS 2010 HIV/AIDS expenditures in Dehong Prefecture were evaluated based on UNAIDS' National AIDS(More)
INTRODUCTION The aims of this study were to determine the accuracy of volumetric measurements of teeth in vitro by cone-beam computed tomography (CBCT) and to analyze the factors affecting their volume measurements from the CBCT data. METHODS We used a sample of CBCT-scanned (voxel sizes: 0.125, 0.20, 0.25, 0.30, and 0.40 mm) and laser-scanned crowns (n =(More)
