Coronary artery disease (CAD) is associated with high mortality and occurs via endothelial injury. Endothelial progenitor cells (EPCs) restore the integrity of the endothelium and protect it from atherosclerosis. In this study, we compared the expression of microRNAs (miRNAs) in EPCs in atherosclerosis patients and normal controls. We found that miR-221(More)
—By analyzing threatens faced by the secure chip nowadays , we point out several disadvantages existing in current commonly adopted settle means, and present a system architecture scheme of the secure chip based on the trusted computing theory. This scheme, which can satisfy the requests of code downloaded by the user himself and multi-cryptographic(More)
In this paper, a nonlinear robust control scheme is considered for a planar gantry crane system. The influence of motion friction and viscous friction of the linear motor and viscous friction of the cable is investigated under different operating conditions. Then, the Lagrange motion equation of the planar gantry crane is setup, which can be described as a(More)
In dual closed loop direct current governor system, startup current is usually much larger than rated current so that current restricting problem must be considered during startup stage of direct current motor. In this paper, a dual closed loop robust control scheme is presented for a direct current governor system with input constraints by using robust(More)
In this paper, an operator based multivariable tracking control design for a robot arm with human-simulated motion mechanism based on human multi-joint viscoelastic properties is proposed by using robust right coprime factorization approach. That is, first, considering the uncertainties of dynamic model consist of measurement error and disturbances, an(More)
