Angiogenesis is a dynamic process that results in the formation of new blood vessels from pre-existing vasculature. This process is regulated by a host of proand anti-angiogenic factors (Iruela-Arispe 1997). When there is an imbalance favoring pro-angiogenic stimuli, the angiogenic switch is thrown (Bergers 2003). Blood vessels dilate and become leaky, pericytes that surround and support mature...

When one solves differential equations, modeling physical phenomena, it is of great importance to take physical constraints into account. More precisely, numerical schemes have to be designed such that discrete solutions satisfy the same constraints as exact solutions. Based on general theory for positivity, with an explicit third-order Runge-Kutta method (we will refer to it as RK3 method) pos...
