Estimating 'regions of attraction' should improve computer models of biological systems

(Âé¶¹ÒùÔº)—Researchers have found an effective means of estimating the "regions of attraction" (ROA) when developing computer models of biological systems – improving the ability of these models to predict how a system ...

A model for development: biologists create first predictive computational model of gene networks

(Âé¶¹ÒùÔº)—As an animal develops from an embryo, its cells take diverse paths, eventually forming different body parts—muscles, bones, heart. In order for each cell to know what to do during development, it follows a ...

Universal transistor serves as a basis to perform any logic function

(Âé¶¹ÒùÔºOrg.com) -- Most of today’s electronics devices contain two different types of field-effect transistors (FETs): n-type (which use electrons as the charge carrier) and p-type (which use holes). Generally, a transistor ...
