Cardiovascular diseases (CVD) are the leading causes of morbidity and mortality worldwide. Although treatment for risk factors for CVD such as hypertension, hyperlipidaemia, obesity, and diabetes has steadily decreased mortality due to cardiovascular events in the last three decades, the underling mechanisms for several CVD remain elusive. It is well known that oxidative stress and inflammation...

A polynomial approach is pursued for locally stabilizing discrete-time linear systems subject to input constraints. Using the Youla-Ku cera parametrization and geometric properties of polyhedra and ellipsoids, the problem of simultaneously deriving a stabilizing controller and the corresponding stability region is cast into standard convex optimization problems solved by linear, second-order co...
