ARMA regularization of cardiac perfusion modeling
Cardiac perfusion modelling using ARMA systems is studied. ARMA is a generalization of a recently proposed exponential approximation technique, which was shown to exhibit better performance than the widely used truncated singular value decomposition ...

Abstract Humanity – the virtue enabling meaningful human connection – is vital to the leadership we need to survive our polycrisis context. As a prerequisite to sustainable human community, the virtue of humanity is considered universal. It has been claimed as a ‘higher‐order virtue’, comprised of and enacted by – but irreducible to – a suite of ‘lower‐
