The spread of an infectious disease is sensitive to the mixing patterns in the population and to precautions people take to reduce the transmission of the disease.

We consider the impact of heterogeneity in susceptibility and infectivity...

This paper describes new research that attempts to address cost and development time bottlenecks in the implementation of high-fi delity human behavior representations. The proposed solution, behavior design patterns (BDPs), is an extension of design patterns in traditional software engineering. A crucial challenge for BDPs, and the fundamental limitation of existing design patterns, is capturi...
