(A) and (B) Effective Hill parameters for the regulatory function fN,M, Eq. (8), with b P = 1 and x0 = 1. (A) Effective Hill coefficient h. (B) Effective inhibition threshold K. (C) and (D) Oscillations described by Eq. (9) with b P = 2, τ = 1, c =1 and x0 = 1. (C) Amplitude of oscillations. (D) Period of oscillations. In C and D the white region represents the nonoscillatory regime, in which the system settles to a fixed point. Color bar labels indicate values in each panel.
