Human effector T cells have been difficult to isolate and characterize due to their phenotypic and functional similarity to the memory subset. In this study, a biochemical approach was used to analyze human effector CD4 T cells generated in vitro by activation with anti-CD3 and autologous monocytes for 3 to 5 days. The resultant effector cells expressed the appropriate activation/differentiatio...

The accuracy of the end-effector motion trajectory is a critical performance indicator for cable-driven parallel mechanisms. This study aims to address problem error during in mechanism. It proposes comprehensive compensation method based on simultaneous application improved sparrow search algorithm and cable length space algorithm, leveraging kinematic analysis. To compensate caused by geometr...

Abstract Because of their elastic links and joints, high-speed parallel robots for pick-and-place operations inevitably suffer from residual vibrations that significantly degrade positioning accuracy. An effective approach based on the input shaping technique is presented in this paper suppressing vibration these robots. After addressing design principle an shaper a robot with flexible actuated...
