Figure 18From: Dynamical modeling of drug effect using hybrid systemsSimulation results for the 3-gene network under drug perturbation (high dosage and short interval): (a-d) state response, trajectory of x 1 versus u , detailed initial trajectory of x 1 versus u , and trajectory of x 1 versus x 3 , respectively. Parameter settings are the same with Figure 16 except u(k τ) = 240 and τ = 2.Back to article page
