Prediction and Dissipation in Biochemical Sensing (1312.5625v1)

Abstract: Cells sense and predict their environment via energy-dissipating pathways. However, it is unclear whether dissipation helps or harms prediction. Here we study dissipation and prediction for a minimal sensory module of receptors that reversibly bind ligand. We find that the module performs short-term prediction optimally when operating in an adiabatic regime where dissipation vanishes. In contrast, beyond a critical forecast interval, prediction becomes most precise in a regime of maximal dissipation, suggesting that dissipative sensing in biological systems can serve to enhance prediction performance.
