We show that there exist infinitely many hyperharmonic integers, and this refutes a conjecture of Mező. In particular, for r=64·(2 α -1)+32, the number h 33 (r) is integer 153 different values α(mod748440), where smallest r equal to 64·(2 2659 -1)+32.

Autoreducibility and mitoticity express weak forms of redundancy of information that a set might possess. We describe many results known about these concepts. Mitoticity always implies autoreducibility, but the converse holds in some situations and fails in others. Among the results we describe are that NP-complete sets are many-one autoreducible and that every many-one autoreducible set is man...

Many clinical and epidemiological studies have shown that the polyunsaturated n-3 fatty acids EPA and DHA from fish and fish oils, provide cardiovascular protection, particularly in the setting of secondary prevention. n-3 Fatty acids beneficially influence a number of cardiometabolic risk factors including blood pressure, cardiac function, vascular reactivity and lipids, as well as having anti...
