Image operations in quantification of atherosclerosis from digitized angiograms.

abstract：BACKGROUND AND OBJECTIVE:Gene regulatory networks (GRNs) are essential for understanding most molecular processes. In this context, the so-called model-free approaches have an advantage modeling the complex topologies behind these dynamic molecular networks, since most GRNs are difficult to map correctly by any other m...
