A simpler model evolved, in which a handful of companies like Oracle, I.B.M. and Hewlett-Packard bought dozens of smaller players and then competed to sell most of the software needed to run a modern business.

And as clinicians increasingly turn to biologically-targeted therapies that exert their effects not only on the tumor cells themselves, but also on the surrounding extracellular matrix, it is especially important that preclinical models evolve in parallel to reliably measure antineoplastic effects and possible mechanisms of de novo and acquired drug resistance.
For example, the connection weights can change over time to model evolving connections in network models.
The conception of port governance models evolves both in time and space because of the confluence of several elements: i) devolution, ii) corporate governance, iii) operational profile, iv) functional autonomy, v) functional pro-activeness, vi) investment responsibility and (vii) financial autonomy (see Verhoeven and Vanoutrive 2012).
