The government is backing a bill that will put into law many of the practices currently licensed case by case by the Human Fertilization and Embryology Authority. Britain is currently one of the nations at the forefront of...
متن کاملPer-Pixel Divisions
We describe a method to perform per pixel divisions using graph ics hardware with a simple iterative algorithm In the worst case the number of rendering passes is for approximate divisions and for accurate divisions The algorithm can be used for D vec tor normalization evaluating complex lighting models and image reconstruction Introduction and Previous Work Graphics hardware can act as a power...
متن کاملOn Noncommutative Involutive Divisions
Buchberger’s algorithm for computing a Gröbner basis solves the ideal membership problem over commutative polynomial rings. In the early 1990’s, an alternative to this algorithm was found, namely the involutive basis algorithm, which provides a Gröbner basis with extra combinatorial properties. Buchberger’s work was generalised to noncommutative polynomial rings by Bergman and Mora during the 1...
متن کاملNumber of Nuclear Divisions
The cell number of the early Drosophila embryo is determined by exactly 13 rounds of synchronous nuclear divisions, allowing cellularization and formation of the embryonic epithelium [1]. The pause in G2 in cycle 14 is controlled by multiple pathways, such as activation of DNA repair checkpoint, progression through S phase, and inhibitory phosphorylation of Cdk1, involving the genes grapes, mei...
متن کاملAutomatic Specialized vs. Non-specialized Sentence Differentiation
Compilation of Languages for Specific Purposes (LSP) corpora is a task which is fraught with several difficulties (mainly time and human effort), because it is not easy to discern between specialized and non-specialized text. The aim of this work is to study automatic specialized vs. non-specialized sentence differentiation. The experiments are carried out on two corpora of sentences extracted ...
