in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...

BACKGROUND Korean ginseng is a well-known medicinal herb that has been widely used in traditional medicine to treat various diseases, including asthma. Ginseng can be classified as white ginseng (WG) or red ginseng (RG), according to processing conditions. In this study, the authors compared the efficacies of these two ginseng types in a mouse model of acute asthma. METHODS To produce the acu...

Abstract This study focuses on stability of weak grid connected voltage source converter (WG‐VSC) in Low‐frequency mode (LFM) (around 1–10 Hz), which is dominated by interactions among phase‐locked loop (PLL), outer control and condition. In order to clearly reveal LFM mechanism WG‐VSC, a simple but effective PLL‐equivalent model has been proposed. First, generic small signal consisted PLL ‘out...

Pseudorandom number generators play an important role to provide security and privacy on radio frequency identification (RFID) tags. In particular, the EPC Class 1 Generation 2 (EPC C1 Gen2) standard uses a pseudorandom number generator in the tag identification protocol. In this paper, we first present a pseudorandom number generator, named the filtering nonlinear feedback shift register using...
