Abstract The highly mutated and transmissible Omicron (BA.1) and its more contagious lineage BA.2 have provoked serious concerns over their decreased sensitivity to the current COVID-19 vaccines and evasion from most anti-SARS-CoV-2 neutralizing antibodies (NAbs).In this study, we explored the possibility of combating the Omicron and BA.2 by constr
In view of problems of small detection range, difficult installation position setting and easy misoperation existed in traditional protection devices for prevention of coal piling wearing tail rope, a protection system for prevention of coal piling wearing tail rope in mine Electronics was designed based on two-dimensional laser radar scanning tech
Robots are typically expected to perform multiple Needs Audit tasks.For realizing multiple tasks using multi-degrees-of-freedom of a robot, priority control was developed.The priority control prioritizes conflicting tasks by projecting lower-priority task velocity into a null space of higher-priority task spaces.Similarly, for realizing two tasks o
Abstract Background The purpose of this study is to evaluate the prognostic factors for sperm retrieval and determine if Y chromosome deletion is associated with deleterious effects on spermatogenesis in non-mosaic Klinefelter patients.Whether Y chromosome deletion determines the sperm retrieval rate in non-mosaic Klinefelter patients has not yet b
