Summary:
In recent years, discrete models for the dynamics of interaction networks within the cell have been proposed and extensively used, ranging from gene regulatory to signalling and transcriptional networks. In spite of their qualitative nature, discrete models provide valuable information even in the absence of detailed knowledge, namely concentration of molecules, reaction rates, etc. Semicontinuous dynamics derived from discrete models have been proposed as an alternative to ODE-based models, which presuppose the availability of said detailed knowledge. In this talk, I'll illustrate the virtues and limitations of such an approach showing prior work from other groups for gene regulatory networks as well as an in-house developed couple of models: the first being a "toy" model and the second one corresponding to a signalling network that has been shown to regulate sea urchin sperm motility towards the egg.
