Before revision:  Furthermore, we give a complete classification by multistationarity of all fully open networks which contain one non-flow (possibly reversible) reaction. Moreover, we obtain new sufficient conditions for establishing multistationarity of certain fully open networks  beyond the one-reaction setting.
After revision:  Using the notion of `embedded network' defined recently by Joshi and Shiu, we provide new sufficient conditions for establishing multistationarity of certain fully open networks beyond the one-reaction setting.
