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.
The jaguar is virtually extinct in the northern part of its original range and survives in reduced numbers only in remote areas of Central and South America; the largest known population exists in the Amazon rainforest.
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.
But it made sense to organize the first major post-Inauguration protest march around women, who are almost fifty-one per cent of the American population, who have been maligned and attacked by the new President, and who make up a group within which every other vulnerable population exists.
But, when ac > bd, the population exists persistently and is harmful after reaching high density.
While the domestic opportunity is still massive, the rest of the planet's 7 billion-ish population exists outside the United States.
We establish that a unique evolutionary stable strategy (ESS) for the population exists.
A significant population exists near CF3-substituted aninines in the top right, which have historically been Ames- (2nd plot) and have higher nitrenium formation energies.
Although successfully eradicated from the affected piggery, fruit bats are considered to be the natural reservoir of the virus and therefore an ongoing risk of re-introduction to the pig population exists.
We thus postulated that a cell population exists in the spleen that under particular microenvironmental conditions is able to reprogram itself and pursue a fate other than the tissue-specific one.
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.
