Sharpness of saturation in harvesting and predation
(American Institute of Mathematical Sciences, 2009-10)
Harvesting and predation occur through contact processes in which the rate at which the managed (prey) population can be found depends on the population size, usually saturating at high densities. Many models incorporate ...
Estimating contact process saturation in sylvatic transmission of Trypanosoma cruzi in the United States
(Public Library of Science, 2010-04)
Although it has been known for nearly a century that strains of Trypanosoma cruzi, the etiological agent for Chagas' disease, are enzootic in the southern U.S., much remains unknown about the dynamics of its transmission ...
An epidemiological approach to the spread of political third parties
(American Insttitue of Mathematical Sciences, 2011-05)
Third political parties are influential in shaping American politics. In this work we study the spread of a third party ideology in a voting population where we assume that party members/activists are more influential in ...
Community resilience in collaborative learning
(American Institute of Mathematical Sciences, 2010-07)
This paper introduces a simplified dynamical systems framework for the study of the mechanisms behind the growth of cooperative learning in large communities. We begin from the simplifying assumption that individual-based ...
