Consider the reaction-diffusion system … m1-ac-mathbf{k},quad mfrac{2acmathbf{k}+ac-mathbf{k}+1}{1+mathbf{k}},quad u(E)<0,quad c1,quad 0<mathbf{k}<frac{1}{a}-1, … . Multiple-interi…

Bistability at all processivity levels. For every choice of $p_k,p_{\ell}\in(0,1)$, there is such a rate-constant vector for which the resulting system admits multiple exponentiall…

Consider the full ERK network and the same network with $k_{\mathrm{on}}=0$, and let a positive steady state mean a steady state with all relevant concentrations positive; call a s…
