Did you know?
WebbFor more information:http://www.iip.ufrn.br/eventsdetail.php?inf===QTUFUN Run-and-tumble motion is a movement pattern exhibited by certain bacteria and other microscopic agents. It consists of an alternating sequence of "runs" and "tumbles": during a run, the agent propels itself in a fixed (or slowly varying) direction, and during a tumble, it remains stationary while it reorients itself in … Visa mer Many bacteria swim, propelled by rotation of the flagella outside the cell body. In contrast to protist flagella, bacterial flagella are rotors and—irrespective of species and type of flagellation—they have only two modes of … Visa mer Theoretically and computationally, run-and-tumble motion can be modeled as a stochastic process. One of the simplest models is based on the following assumptions: Visa mer 1. ^ Berg 2004. 2. ^ Cates & Tailleur 2015. 3. ^ Sowa & Berry 2008.
