In general, the noise has negative effects on persistence of the disease.
Over-expressing IDO utilizing adenovirus or transposon-mediated gene therapy in lung tissue has been shown to have potent effects on persistence of allogeneic lung transplants, associated with suppression of allo-reactive T-cells (Swanson et al., 2004; Liu et al., 2006a).
Home-range sizes of order 1 10 km cited for many California rockfish species [26], [35], for example, may be significant in terms of their effects on persistence for reserves that are often the same order of magnitude in size [25], particularly when the distribution and amount of harvest effort is not controlled.
In either case, the observation of an inversion effect on persistence would demonstrate an effect of experience-dependent feedback on the visual perception of global form.
We conclude that spatial uncertainty has the greatest effect on persistence when the amount and arrangement of suitable habitat are such that habitat capacity is near the minimum required for persistence.
This suggests that face-selectivity and the inversion effect on persistence may be independent since the effect of inversion on persistence was not limited to faces or face-selective cortex.
Replicator mobility is clearly advantageous for the coexistence of the metabolic replicator community in general: increasing any one or both of the diffusion parameters (D and D r ) and the size of the replication neighbourhood (r) has a positive effect on the persistence of the system, as well as on the average density of replicators on the surface.
Certainly, it is known that the under-predictions for Cat 1 chemicals obtained with organotypic methods like BCOP and ICE, which were developed to detect immediate severe effects, are more likely for chemicals classified in vivo based only on persistence of effects than for those classified based on severity (ICCVAM 2006a, b, 2007).
The structure of the reference population is expected to have an effect on the persistence of accuracies because it affects how well the genetic variance of QTL can be assigned to markers near the QTL as opposed to markers that are more distant.
In order to get some insight into the behavior of the parameter (k_{2}) and its effect on the persistence of the population, we use the real life data for the vital rates for four different species.
