Figure 19

Classification of Relaxation Oscillators into substrate-depletion, activator-inhibitor and toggle based. Note that although the mechanistic networks are quite variable, the underling operation is the same as shown in the stylized column. Type codes: SD = Substrate-Depletion; AI = Activator-Inhibitor; SD/T = Substrate-Depletion/Toggle. The stylized form is generated by computing the Jacobian matrix for each network. Elements in the Jacobian indicate how each species influences changes in another. Model a) corresponds to model c) in Figure 2 of (Tyson et al. 2003) and model e) to model b) in Figure 2 of (Tyson et al. 2003)
