Packaging stiff polymers in small containers: A molecular dynamics study
2016-09-28T10:00:00-04:00
Author(s): D. C. Rapaport
The question of how stiff polymers are able to pack into small containers is particularly relevant to the study of DNA packaging in viruses. A reduced version of the problem based on coarse-grained representations of the main components of the system—the DNA polymer and the spherical viral capsid—ha…

Fixation of competing strategies when interacting agents differ in the time scale of strategy updating
2016-09-19T10:00:00-04:00
Author(s): Jianlei Zhang, Franz J. Weissing, and Ming Cao
A commonly used assumption in evolutionary game theory is that natural selection acts on individuals in the same time scale; e.g., players use the same frequency to update their strategies. Variation in learning rates within populations suggests that evolutionary game theory may not necessarily be r…
