The observed small scale spatial diversity of var genes suggests that var genetics could greatly inform current malaria mapping approaches and predict complex malaria population dynamics due to the import of var types to areas where no widespread pre-existing immunity in the population exists.
In a world where more than a fifth of the population exists on a dollar a day or less and foreign aid has dropped, information technology may be a cost-cutting device rather than an extravagance, Mr. Annan said at his news conference.
The Occupy movement will seize happily upon this line, from June 3, 1940, when Orwell responded in his diary to a letter in The Daily Telegraph lamenting that the rich would have to part with their cooks during the war: "Apparently nothing will ever teach these people that the other 99 percent of the population exist".
But, when ac > bd, the population exists persistently and is harmful after reaching high density.
We establish that a unique evolutionary stable strategy (ESS) for the population exists.
Then, Theorem 1 tells us that if R0 ≤ 1 then the population dies out; otherwise, (1) possesses a globally asymptotically stable positive equilibrium and hence the population exists persistently.
For example, researchers may be interested in analyzing the recurrence of a disease but many individuals may never have an experience or a recurrence, therefore, a cured fraction of the population exist.
It is not known what the basic reproductive ratio of the second wave of a pandemic will be and it cannot be measured since partial immunity in the population exists.
In the higher mutation rates regime, black dotline and black line describe the population is likely to move to the fittest class so that the population exists in the form of coexistence of A and a.
For comparison of these subgroups, 95% confidence intervals were generated by multiplying the fpc-corrected standard error of the mean by 1.96 (95% of the population exists within about two standard deviations of the mean).
