Reduction of multiscale stochastic biochemical reaction networks using exact moment derivation

Period distributions of full and reduced models.
(A) Fourier transforms of stochastic trajectories with about 104 cycles of the EMB model, the AMB model and the full model with ϵ = 0.1. (B) After partitioning the trajectory of 104 cycles into 2⋅103 trajectories so that each trajectory consists of about 5 cycles, the autocorrelation of each trajectory is calculated to estimate the period of each trajectory. The period distribution of 2⋅103 trajectories of the EMB model (above) better captures that of the full model with ϵ = 0.1 than that of the AMB model (bottom). (C-D) The mean and the standard deviation of period distributions of the EMB model, the AMB model, and the full model with ϵ = 10, 1, 0.1.
