On 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...
متن کاملEffects of LETS glycoprotein on cell motility.
Addition of LETS glycoprotein to normal or transformed cells produces increased migration of the cells, as determined by formation of phagokinetic tracks on gold particle-coated coverslips. These tracks arise by a combination of phagocytosis of the gold particles and cellular migration. Increased motility is also evident on plastic in the absence of gold particles. The added LETS protein attach...

متن کاملConstructability 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...
