The American College of Cardiology Foundation and the American Heart Association have jointly produced clinical practice guidelines for diagnosis and treatment of cardiovascular diseases since 1980. Writing committees are charged with assessing the evidence as an independent group of authors and with developing, updating, or revising recommendations for clinical practice. Practice guidelines ar...

In this paper we compare Wadler’s CP calculus for classical linear processes to a linear version of Parigot’s λμ calculus for classical logic. We conclude that linear λμ is “more or less” CP, in that it equationally corresponds to a polarized version of CP. The comparison is made by extending a technique from Melliès and Tabareau’s tensor logic that correlates negation with polarization. The po...

When we consider the practically universal use in all educational institutions of a system of marks, whether numbers or letters, to indicate scholastic attainment of the pupils or students in these institutions, and when we remember how very great stress is laid by teachers and pupils alike upon these marks as real measures or indicators of attainment, we can but be astonished att he blind fait...

AIM To estimate the potential cost effectiveness of photodynamic therapy (PDT) with verteporfin in the UK setting. METHODS Using data from a variety of sources a Markov model was built to produce estimates of the cost effectiveness (incremental cost per quality adjusted life year (QALY) and incremental cost per vision year gained) of PDT for two cohorts of patients (one with starting visual a...
