The persistence conjecture is a long-standing open problem in chemical reaction network theory. It concerns the behavior of solutions to coupled ODE systems that arise from applying mass-action kinetics to a network of chemical reactions. The idea is that if all reactions are reversible in a weak sense, then no species can go extinct. A notion that has been found useful in thinking about persis...

Most accidents happens because of lack of Visibility and not Driver’s reaction on time whenan accident occurs. Increasing required Time for driver’s reaction caused to decreasingaccidents on roadways .intelligent vehicle networks brings enough time for reaction by sendingalert and alternate messages to vehicles on roadway. Main propose in this paper is aroundmodulation on Reception interval Saf...

      In order to prepare polyurethane elastomers with acceptable physical properties and good biocompatibility, novel polyurethane networks were synthesized via curing reaction of epoxy-terminated polyurethane prepolymers (EUPs) with hexamethylene diamine. EUPs were prepared from reaction of glycidol with NCO-terminated polyurethanes (ITPs). ITPs were also synthesized from reaction of one equi...

For large and complex reacting systems, computational efficiency becomes a critical issue in process simulation, optimization and model-based control. Mechanism simplification is often a necessity to improve computational speed. We present a novel approach to simplification of reaction networks that formulates the model reduction problem as an optimization problem and solves it using geneti...

A biochemical reaction network is the system in which biochemical species interact through various reaction channels. Many chemical or biochemical systems such as signal transduction pathways, gene regulatory networks and enzymatic reaction networks are modelled as biochemical reaction networks. To describe the time evolution of such systems quantitatively or qualitatively, mathematical methods...
