Reduction of multiscale stochastic biochemical reaction networks using exact moment derivation
Fig 1
Model diagram of the feedforward network of the full model and the reduced model.
In the diagram of the full model (left), red arrows indicate fast reactions. In the diagram of the reduced model (right), which consists of slow species S2 and S4 and slow reactions, 〈S1〉 and 〈S1S3〉 represent conditional moments, 〈X1|X2, X4〉 and 〈X1X3|X2, X4〉, respectively. In both of the diagrams, degradation reactions are not shown, for simplicity.
