A General Framework for Closed Loop Negative Feedback Multivariable Physiological Control Systems: Existence, Uniqueness, and Stability of Homeostatic Equilibrium Points by Anna Procopio, Annarita Tedesco, Fabrizio Lo Regio, Giuseppe Cesarelli, Leandro Donisi, Carlo Ricciardi, Alessio Merola, Alfonso Maria Ponsiglione, Maria Romano, Francesco Montefusco, Carlo Cosentino, Francesco Amato

“…To this regard, in this paper, the existence, possible uniqueness and stability properties of the homeostatic equilibrium points of the general model are investigated; the theoretical framework is then illustrated through two real-world case-studies: (i) the PI3K/AKT/mTOR pathway nonlinear dynamics, a critical regulator of cellular growth, proliferation, and survival; (ii) the control mechanism of the neuromuscular stretch reflex, among the prime triggers implicated in postural control. …”
