Optimal concentration and gradient sensing by perfect monitors
Farshid Jafarpour
Cells often estimate chemical concentrations from only a few diffusing molecules, whose stochastic motion limits sensing precision. We consider a perfect monitoring instrument that…

Optimal information transmission in a sequential model for cell division
Krishna P. Ramachandran, Motasem ElGamel, Farshid Jafarpour +1
In proliferating cell populations, adaptive changes to biochemical reactions can change a cell's division time, which in turn can change the population size. However, biochemical r…
