(a) In regular growth/division events the relevant fluctuations in the size increment are of order Δl0; however, in anomalous growth/division events the dominant ones are of order l0. The green lines indicate either the actual (dark) or putative (light) division sites. (b) Our model, by neglecting small scale fluctuations in size changes, assumes that the length of a cell is well represented by the number of units l0 contained in a cell and establishes probabilities for the transitions between those states, Pnm:=Pmn (from m to n), that depend on the division pattern (see text). Inset: the efficiency of the division machinery is described by means of the parameter α: cells either grow with probability 1 − α or grow/divide with a probability α (division is considered to happen instantaneously).
