We analyzed the improvement of prostate cancer detection rate (PCDR) in Chinese Han population and summarized the characteristics of prostate cancer (PCa) with the advancement of prostate biopsy technologies. From March 1999 to March 2015, 3762 patients underwent the systematic 6-, 8- or 13-core biopsy, guided by finger or transrectal ultrasound (TRUS) at our center. The PCDR under different PS...

The aim of the present study was to evaluate the value of systematic 12- and 13-core biopsies, guided by transrectal ultrasound (TRUS) or magnetic resonance imaging (MRI), with regard to the prostate cancer detection rate (PCDR). Between July 1999 and June 2012, 2,707 patients were recruited to the Department of Urology, The First Affiliated Hospital of Nanjing Medical University (Nanjing, Chin...

Quantitative PCR assays are now the standard method for viral diagnostics. These assays must be specific, as well as sensitive, to detect the potentially low starting copy number of viral genomic material. We describe a new technique, polymerase chain displacement reaction (PCDR), which uses multiple nested primers in a rapid, capped, one-tube reaction that increases the sensitivity of normal q...

In the past few years, the graphics processing units (GPU) has become trend in high performance computing (HPC). The newest Top500 list was showed three supercomputers contain GPU accelerator on Top10 in Nov. 2010. The role of the GPU accelerator has become more and more important for scientific computing and computational fluid dynamic (CFD) to obtain result quickly and efficiently. The GPU ha...

Emissions of greenhouse gases and growing amounts waste plastic are serious environmental threats that need urgent attention. The current methods dedicated to recycling still insufficient it is necessary search for new technologies management. pyrolysis-catalytic dry reforming (PCDR) a promising pro-environmental way employed the reduction both CO2 remains. PCDR allows resource recovery, conver...

The Kriging surrogate model in complex simulation problems uses as few expensive objectives possible to establish a global or local approximate interpolation. However, due the inversion of covariance correlation matrix and solving Kriging-related parameters, approximation process for high-dimensional is time consuming even impossible construct. For this reason, modeling method through principal...

A one-step conservative level set method, combined with a global mass correction method, is developed in this study to simulate the incompressible two-phase flows. The present framework do not need to solve the conservative level set scheme at two separated steps, and the global mass can be exactly conserved. The present method is then more efficient than two-step conservative level set scheme....

A wireless sensor network (WSN) consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure. and to cooperatively pass their data through the network to a main location. The process of uploading new code or changing the functionality of existing code is called Wireless reprogramming. For security reasons, every code ...
