Abstract: Synchronization is a ubiquitous feature in many natural systems and nonlinear science. In this paper, the synchronization in complete network consisting of n nodes is studied. Each node is connected to all other nodes by linear coupling and it is represented by a system of ordinary differential equations of FitzHugh-Nagumo type which i...

Abstract: This paper presents a new result on delay-dependent exponential stability for nonlinear linear systems with interval time-varying delay. By constructing a set of improved Lyapunov-Krasovskii functionals combined with Wirtinger-based integral inequality, a new delay-dependent condition is established in terms of linear matrix inequality...

Abstract: The ecdysone inducible system was generated for checking the toxicity of target gene which was transected into the cells. The transcription unit, modified ecdysone receptor (IND) was cloned into vector pcDNA-Dest40 to form the new inducible expression plasmid pDest40-IND via cloning technique. A clear band with size about 487bp of PCR ...
