Run-and-tumble motion with step-like responses to a stochastic input
Subrata Dev, Sakuntala Chatterjee
We study a simple run-and-tumble random walk whose switching frequency from run mode to tumble mode and the reverse depend on a stochastic signal. We consider a particularly sharp,…

Optimal methylation noise for best chemotactic performance of {\sl E. coli}
Subrata Dev, Sakuntala Chatterjee
In response to a concentration gradient of nutrient, E. coli bacterium modulates the rotational bias of flagellar motors which control its run-and-tumble motion, to migrate towards…

Optimal search in E.coli chemotaxis
Subrata Dev, Sakuntala Chatterjee
We study chemotaxis of a single {\sl E.coli} bacterium in a medium where the nutrient chemical is also undergoing diffusion and its concentration has the form of a Gaussian whose w…
