OBJECTIVES This study aimed to: (i) define the clinical pharmacokinetics of mycophenolic acid (MPA) in Chinese liver transplant recipients; and (ii) develop a regression model best fitted for the prediction of MPA area under the plasma concentration-time curve from 0 to 12 hours (AUC(12)) by abbreviated sampling strategy. METHODS Forty liver transplant(More)
Large scale integration of electric vehicles (EVs) provides new ideas for power system stability and control. Connected to power grid, EVs can be taken as distributed energy storage and thus cooperate with traditional automatic generation control (AGC) units to help stabilize the system frequency and achieve energy saving. On the basis of previous(More)
Electric vehicles (EVs) can act as distributed storages and loads while they are connected to the grid. Vehicle-to-grid (V2G) system can provide active power support and frequency regulation services to mitigate the intermittence of renewable energy sources (RES), and balance the loads in the grid. Through V2G technologies, EVs can provide power to the(More)
The paper presents a new framework for the maths development which is called maths differance. There are three typical maths differaence: prove, axiom and shift, and also some others. What is the essential part of maths? Maybe non-maths students will say calculation,and some maths students will say prove, but the mathematician G.H.Hardy says that strictly(More)
