The scaling of contact rates with population density for the infectious disease models
Contact rates and patterns among individuals in a geographic area drive transmission of directly-transmitted pathogens, making it essential to understand and estimate contacts for simulation of disease dynamics. Under the uniform mixing assumption, one of two mechanisms is typically used to describe the relation between contact rate and population density: density-dependent or frequency-dependent. Based on… Read more

Exploiting Sparsity and Equation-Free Architectures in Complex Systems
Complex systems exhibit dynamics that typically evolve on low-dimensional attractors and may have sparse representation in some optimal basis. Recently developed compressive sensing techniques exploit this sparsity for state reconstruction and/or categorical identification from limited measurements. We argue that data-driven dimensionality reduction methods integrate naturally with sparse sensing in the context of complex systems. This… Read more

2018 IDM Annual Symposium
The 2018 IDM Annual Symposium covered a wide range of topics. Multiple talks focused on small area estimation in public health and demography. Other talks discussed access, treatment, and all-cause mortality in child health. Pandemic preparedness, pandemics and big data, and seasonality of pandemic influenza talks were also given. Read more
