BACKGROUND Previous studies suggested that expression of cyclin-dependent kinase 5 (CDK5) may promote the migration and invasion of human glioma cells. In this study, we aimed to evaluate the clinical value of CDK5 in different grades of glioma in relation to Ki-67 labeling index (LI). METHODS We firstly assessed by immunohistochemistry the expression of(More)
Aiming at the slow dynamic response and the chattering problem from conventional exponential reaching law sliding mode applied in permanent magnet synchronous motor vector control in current loop, firstly this paper used weighted integral type sliding mode control algorithm to design the current loop controller. For the second step, the stability of the(More)
—In order to detect grid harmonic and reactive current precisely and real time, this paper arrived at a method of harmonic and reactive current real-time detection applied to active power filter based on the three-phase circuit instantaneous reactive power theory. With Matlab simulation software, researches on simulation of harmonic detection means are(More)
