In most studies that use the concept of diffusion, there is an implicit assumption that the innovation being adopted has reached its final development or commercial stage.
In terms of information diffusion, there are a few studies on the relation of 'impact of number of exposures' to different outputs (e.g., hashtag adoption of Twitter [33] and Facebook fan page creation [56]).
The thing about the F-H space, is that diffusion there is constrained to follow the shape of the dendrites; that is, nothing diffuses from one cell to another or between physically nearby dendrites that are only connected far apart on the dendritic tree.
There are also two conductivity coefficients c ζ and c η which determine how much diffusion there is in the isophote and gradient directions respectively.
Apparently, the more axial diffusion there is on these clusters the greater the negative impact it has on performance.
In experimental studies on tumor growth, whenever the time evolution of the relative volume of a tumor in an untreated (control) group can be fitted by a Gompertz diffusion process there is a possibility that an antiproliferative therapy, which modifies the growth rate of the process that fits the treated group, may also affect its variability.
In relatively short columns there is quasi-kinetic behaviour; as the retention time of the breakthrough curve in the column increases relative to the characteristic diffusion time there is a transition region, whereas for relatively long columns constant-pattern breakthrough curves are observed.
While the media discourse on smart grids is certainly in the early stages of development and diffusion, there is something of an inexorable quality about the discourse.
This is a pitfall of using the ADC as a measure for molecular diffusion; there is no optimal combination of b-values, because the amount of microperfusion determines the optimal sequence of b-values and this is not known a priori.
On a team there is a diffusion of responsibility, as social physiologists would say, compared with the performance of an individual athlete".
