Heart failure (HF) is a global health concern with high incidence and mortality rates. Approximately 2% of the developed Western population suffers from HF, and the prevalence of the disease rapidly increases with age [1,2,3]. Based on the left ventricular ejection fraction (EF) at the time...
Difference constraints have been used for termination analysis in the literature, where they denote relational inequalities of the form $$x' \le y + c$
a control circuit for receiving the retard signal, and in response, providing a control voltage, the control voltage having a magnitude relative to a difference between a transition of the input signal and a transition of the output signal; a voltage controlled delay circuit, coupled to the co...
