background: classification of molar gestation into complete hydatidiform mole (chm) and partial hydatidiform mole (phm) is done according to clinical, ultrasonographic, histologic and genetic criteria. however, making a distinction between chm and phm using histologic criteria alone may be difficult and several studies have shown that misclassifications are frequent, even for experienced pathol...

This paper presents a program transformation, representation analysis, that makes it possible for languages with polymorphic types, such as ML, to use unboxed data representations in monomorphic code. The solution the paper presents involves the use of coercions to convert back and forth between unboxed representations used by monomorphic functions to the boxed representation used by polymorphi...

A bidirectional transformation is a pair of mappings between source and view data objects, one in each direction. When the view is modified, the source is updated accordingly with respect to some laws. Over the years, a lot of effort has been made to offer better language support for programming such transformations. In particular, a technique known as bidirectionalization is able to analyze an...

Bi2O3 is an excellent ceramic candidate for transformation-mismatch plasticity because of its low melting point, its allotropic nature and the rapid creep rate of its high-temperature d-phase. Transformation-mismatch plasticity, which has been reported in many polymorphic metals, alloys and composites [1], is a deformation mechanism taking place during a phase transformation: internal mismatch ...

In this work, solvent-mediated polymorphic transformation of metastable Form II to stable Form I of Buspirone Hydrochloride (BUS-HCl) was studied. The polymorphic transformation was monitored using in-situ Raman spectroscopy. The solvent-mediated transformation process is governed by the dissolution of Form II and the nucleation and subsequent growth of Form I. The model parameters for each of ...

Polymorphic materials which are subjected to an external stress while their temperature is repeatedly cycled about their phase transformation range experience, on average, Newtonian flow, which is driven by the biasing of internal transformation mismatch stresses by the external stress (1). This phenomenon, termed transformation superplasticity, is well documented for metals (as reviewed in Ref...

The effects of polymorphic transition for the impact of a 27NCD10 steel projectile on a 27NCD10 steel target at 1280 m/s is presented. Comparisons between results of 2D numerical calculations performed with and without polymorphic transition show the influence of this phenomenon on stress distribution and tension zones in the target and in the projectile. Good agreement between experimental and...
