Figure 3. Lifetime from the full-master-equation trajectories.

Lifetimes as a function of system volume for constant burst , each normalised to its corresponding system. (a) No burst, . (b) Higher burst, for monomers , dimers and trimers . Note that the system becomes insensitive to at large enough , as the linear-noise approximation predicts (see “Low confinement: the linear-noise approximation” in “Results”). As volume decreases, the system departs from linear-noise behaviour. Note that trimers are insensitive to volume as they are not a reactant in a non-linear reaction.
