Fig. 5From: On the modeling and analysis of the biological regulatory network of NF-\({\kappa }\)B activation in HIV-1 infectionEvolution of clock variable \(h_v\). Here, \(dh_v\)/dt = 1 represents the rate of evolution of clock \(h_v\) associated with gene v, which evolves from low level to higher level 1 Ahmad et al. (2008). When a delay is measured then the respective clock is reset (\(h_v \leftarrow 0\))Back to article page
