Several corpora have been annotated with negation scope—the set of words whose meaning is negated by a cue like the word “not”—leading to the development of classifiers that detect negation scope with high accuracy. We show that for nearly all of these corpora, this high accuracy can be attributed to a single fact: they frequently annotate negation scope as a single span of text delimited by pu...

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...
