Sir: Clinical and nutritional studies have indicated that high cholesterol levels in the blood may be one of the major causes of atherosclerosis and coronary heart disease. In this context the metabolism of cholesterol in liver is of paramount importance because liver seems to be the sole organ supplying serum cholesterol and because the conversion of cholesterol into bile acids in liver is qua...

We present an extension of the Hindley-Milner type system that supports a generous class of type constructors called functors, and provide a parametrically polymorphic algorithm for their mapping, i.e. for applying a function to each datum appearing in a value of constructed type. The algorithm comes from shape theory, which provides a uniform method for locating data within a shape. The result...

This paper proposes a novel technique for separating single channel recording of speech mixture using a hybrid of maximum likelihood and maximum a posteriori estimators. In addition, the new algorithm proposes a new approach that accounts for the time structure of the source signals by encoding them into a set of basis filters that are characteristically the most significant. Real time testing ...
