Constructability of Trip-lets
A trip-let is an object as shown on the cover of Hofstadter’s book Gödel, Escher, Bach: a solid, threedimensional object that, when viewed from three orthogonal directions, shows three different letters. In this paper we consider two problems related to the construction of such objects for a given set of three letters. First, we want to know whether the silhouettes of the object correspond to t...
متن کاملOn Desugaring Polymorphic Lets
Existing type literature has conflicting views on desugaring polymorphic lets to lambda terms. The conflict arises because, in certain cases, desugaring does not preserve typing. We describe a transformation of polymorphic lets to monomorphic lets such that, when the monomorphic lets are desugared, the typing is preserved. Our transformation requires no changes to either term or type syntax. Th...

Subjects in this cohort who were heterozygous for protein C deficiency did not suffer from venous thromboembolism. Family studies in four of the protein C deficient individuals showed autosomal inheritance of the defect. These findings seemed in cont...
