FIG. 3.

(color online). Simulation results for the intrinsic mechanism under a constant input X(t) = c: (A) Illustration of the intrinsic coupling model. (B) B_eff versus c by Eq. (5) for J = 0, 1, 2 and h₀(J) = h_eff (1 + e^−J)/2. The red line is the Hill function with h_eff = 10.3, while the blue line is the Hill function with a coefficient h₀(J = 2). (C) ρ_max versus J. Symbols are simulation results, compared to the theory (blue lines) by Eq. (6). (D) Δt_1/2, T_cw, and T_ccw versus J.
