Aims
We assessed long‐term effects of cardiac contractility modulation delivered by the Optimizer Smart system on quality of life, left ventricular ejection fraction (LVEF), mortality and heart failure and cardiovascular hospitalizations.
Methods and results
CCM‐REG is a prospective registry study including 503 patients from 51 European centres. Effects were evaluated in three terciles of LVEF (≤25%,...
Methods of Computer Algebra have shown to be useful when formally verifying data-centric hardware designs. This has been demonstrated especially for cases where complex arithmetic computations are tightly coupled with the system's control structures at the bit level. As a consequence of current design trends, however, more and more functionality that was traditionally implemented in hardware is now...
In formal verification, proof logging is a technique for automatically reviewing the reasoning steps of a proof engine by a separate tool. This is useful for enhancing the confidence in the prover's result, especially in the case of a positive answer when no counterexample exists. Mature proof logging techniques exist for single-theory provers. SMT solvers, however, combine several theories so that...
