Grid portals are web gateways aiming at concealing the underlying infrastructure through a pervasive, transparent, user-friendly, ubiquitous and seamless access to heterogeneous and geographically spread resources (i.e. storage, computational facilities, services, sensors, network and databases).
This suggests that whatever exogenous factors motivate early participants to start sending messages, the consequence is that they create random seeding in the online network: they spur focuses of early activity that are topologically heterogeneous and that spread through low threshold individuals.
This heterogeneous DNA methylation pattern could be caused by the heterogeneous and random spreading of the demethylating agent in the cells, and the insensitivity of some cells to these agents.
Otherwise, rankings can become a noisy indicator of players' strengths, while effort cost and heterogeneous prize spread can be of little relevance to players' effort choices.
For heterogeneous systems, spread rate and burned area are significantly reduced as the degree of disorder increases.
In patients with DCM, ventricular dilatation and replacement fibrosis lead to a heterogeneous excitation spread across the LV wall with a delay in intraventricular conduction and a left bundle branch block morphology on the ECG.
These results open a novel view where KCs overall are universal cortical phenomena, but each KC may variably involve small or large cortical regions and spread in variable directions, allowing flexible and heterogeneous contributions to sleep homeostasis and memory consolidation.
The pattern of CWD spread is spatially heterogeneous and not a monotonic wave-front (Conner and Miller 2004; Miller and Conner 2005; Farnsworth et al. 2006), suggesting that numerous factors influence spread (Hastings et al. 2005).
As a result of rapid growth and insufficient blood supply, solid tumours demonstrate hypoxia and necrosis in heterogeneous spread regions (Chapman, 1984; Vaupel et al, 1989).
In the time it took to find out, the cancer would have continued to spread, becoming more molecularly heterogeneous and even more difficult to treat the next time around.
