Nevertheless, the time-scale of spreading was very slow and resulted in typical tauopathy with aggregates and tangles, while neuro-degeneration was minimal or absent [44].
From the spreading of infectious diseases [9] to political opinions [10], the substrate structure over which pathogens or opinions are transmitted plays a crucial role in determining the large-scale pattern of spreading dynamics [8], [11].
This allows traffickers economies of scale to spread out the, say, $500,000 fee pilots of small aircraft or go-fast boats often charge.
However, rate and scale of spread depends largely on dispersal dynamics and interplay with factors such as fitness costs, spatially variable selection pressure and whether resistance alleles are spreading through an established population or being carried by populations colonizing new territory.
The speed and scale of spread of this complex interdisciplinary inpatient care program are noteworthy, given the well-documented difficulty of disseminating successful practices throughout large, complex organizations [ 19].
At the smaller scale of spread of within a few kilometers, which the coarsely resolved available data cannot resolve, other processes may have become important, including physical transport of virus by currents (associated with waste products [ 5, 27 ]), escaped or wild fish (31 ), or vectors (such as sea lice) (32 ) moving between neighboring farms.
The method is validated against simulations wherein the flow is fully resolved over all length scales, and experiments of spreading droplets and droplets sliding down an inclined substrate.
More importantly, we investigate the effects of the variable diffusion rate and the intrinsic growth rate on the scale of information spreading in networks.
Growth is the very short time scale of any spreading flow.
He's counting on leveraging off of AMD's global scale to spread his company's technology.
The key will be the integration of the technology and product development of its different alliances so that it can reap benefits of scale by spreading engineering and development work over a wider range of products.
