Analysis of the transient state after coupling the subnetworks (t > 250 s) reveals that the SF and super-hub networks have the fastest response. The results of curve fitting to an exponential function r = r0 − Aexp[−(t − t0)/τ] are summarized in Table 1. The response to coupling the subnetworks is fastest in the SF (τ = 3.9 s) and super-hub (τ = 4.0 s) networks, followed by the random networks (τ = 4.7 s) (Figure 3C). For the SW network, the time constant τ is 10.2 s.
