The Fisher-Kolmogorov model is a reaction-diffusion equation that has been used to describe collective cell spreading driven by cell migration, characterised by a cell diffusivity, D, and carrying capacity limited proliferation with proliferation rate, λ, and carrying capacity density, K.
Our results reveal a mechanism of efficient HIV-1 cell-to-cell spread driven by MDM capture of HIV-1+ T cells.
Introductions of the species over long distances and between continents has been associated with international trade routes via shipping and overland spread driven by human movement and transport routes, both facilitated by the endophilic behavior of the two species (Nawrocki and Hawley, 1987; Tatem et al., 2006; Hofhuis et al., 2009).
Once transgenic organisms bearing the gene drive are constructed in the laboratory, they must be released into the wild to mate with wild-type individuals in order to begin the process of spreading the drive through the wild population.
Releasing Drive B, a precision drive which would exclusively spread through Drive A but not the wild-type allele, would similarly replace Drive A with a unique sequence.
After the layout and spread, drive the stakes and tie off loosely.
We inferred that the landslide and, more specifically, lateral spread drove the river terrace in the direction of the Hanumante River.
We modelled the stratified dispersal of an airborne pathogen population in order to identify the spatial patterns of cultivar mixtures that could slow epidemic spread driven by dual dispersal mechanisms acting over both short and long distances.
In contrast, several epidemiological observations, such as spatially structured diffusion patterns [ 18, 19] and hierarchical spread driven by population size and distance, in gravity models [ 20], have not been evident from phylogenetic methods [ 16, 21, 22].
