Before revision:  We emphasize that no feedback loops are present in the system, and therefore our findings identify a novel class of noise-induced transitions , based on both features of noise nonlinearity and boundedness .
After revision:  We emphasize that no feedback loops are present in the system, and therefore our findings identify a novel class of noise-induced transitions appears to be strongly dependent on the type of noise adopted, and on the degree of nonlinearity present in the system .
