Before revision: It has recently been shown that structural conditions on the reaction network, rather than a ` fine-tuning' of system parameters, often suffice to impart ` absolute concentration robustness' on a wide class of biologically relevant, deterministically modeled mass-action systems [Shinar and Feinberg, Science, 2010].
