Parameter sweep analysis of the Schlögl model.

<p>Results of a PSA-1D on the Schlögl model, in which the value of the stochastic constant is varied in the interval (the set of reactions and the values of all other parameters are given in Tables 4 and 5 in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0091963#pone.0091963.s001" target="_blank">Text S1</a>). Each frequency distribution is calculated according to simulations executed by cuTauLeaping, measuring the amount of the molecular species at the time instant a.u., considering ten different values of the stochastic constant within the sweep interval. The figure shows that increasing values of induce a decrease (increment) in the frequency distribution of concerning the low (high) steady state, with intermediate values of characterized by an effective bistable behavior.
