Charge Density Evolution Governing Interfacial Friction

Journal of the American Chemical Society, 2023
It is well-known that the electron nature of a solid in contact plays a predominant role in determining the many properties of the contact systems, but the general rules of electron coupling that govern interfacial friction remain an open issue for the surface/interface community.

Evolution of Density-Dependent Cooperation

Bulletin of Mathematical Biology, 2014
Cooperation is surprisingly common in life despite of its vulnerability to selfish cheating, i.e. defecting. Defectors do not contribute to common resources but take the advantage of cooperators' investments. Therefore, the emergence and maintenance of cooperation have been considered irrational phenomena.

Evolution of Complex Density-Dependent Dispersal Strategies

Bulletin of Mathematical Biology, 2012
The question of how dispersal behavior is adaptive and how it responds to changes in selection pressure is more relevant than ever, as anthropogenic habitat alteration and climate change accelerate around the world. In metapopulation models where local populations are large, and thus local population size is measured in densities, density-dependent ...

A New Fast Density Evolution

2006 IEEE Information Theory Workshop, 2006
Density evolution for LDPC codes predicts asymptotic performance and serves as a practical design tool for designing top performing structures [1]. Many papers advocate the use of exit chart methods and other approximations, proclaiming that density evolution is computationally too intensive.
