Structure and Stability of Certain Chemical Networks and Applications to   the Kinetic Proofreading Model of T-Cell Receptor Signal Transduction
  This paper deals with the theory of structure, stability, robustness, and stabilization for an appealing class of nonlinear systems which arises in the analysis of chemical networks.   The results given here extend, but are also heavily based upon, certain previous work by Feinberg, Horn, and Jackson, of which a self-contained and streamlined exposition is included.   The theoretical conclusions are illustrated through an application to the kinetic proofreading model proposed by McKeithan for T-cell receptor signal transduction. (Update includes, among other topics, remarks on extensions to certain systems with Michaelis-Menten kinetics.)
