Methods of upper wind measurements used in operational meteorology have been reviewed to provide guidance to those developing wind profiler radar systems.The main limitations of the various methods of tracking weather balloons are identified using results gymnastics wall decals from the WMO radiosonde comparisons and additional tests in the United
Guizhou Province is located in Southwest of China, with many earthbath facial wipes mountains and hills, and is a typical karst topography and geomorphology area with frequent geological disasters such as collapses and landslides.The existing dangerous rock mass in the Xiaotunyan collapse zone in Sinan County has large range and volume, and fissure
Imprinted genes play important roles on embryonic development.Aiming at the stillbirths in fat-1 transgenic foetuses of sheep, we detected the DNA methylation levels of candidate CpG regions in five imprinted genes (h19, igf2, igf2r, dlk1 and gtl2) of diverse tissues in the sheep foetuses, including both male and female fat-1 transgenic stillbirths
In order to successfully achieve mass production in NAND flash memory, a novel test procedure has been proposed to electrically detect and screen the channel hole defects, such as Not-Open, Bowing, and Bending, which are unique in high-density 3D NAND flash memory.Since channel hole defects lead to catastrophic failure (i.e., malfunction of basic N
