Host movement, transmission hot spots, and vector-borne disease dynamics on spatial networks
Omar Saucedo, Joseph H. Tien
We examine how spatial heterogeneity combines with mobility network structure to influence vector-borne disease dynamics. Specifically, we consider a Ross-Macdonald-type disease mo…
Sentinel node approach to monitoring online COVID-19 misinformation
Matthew T. Osborne, Samuel S. Malloy, Erik C. Nisbet +2
Understanding how different online communities engage with COVID-19 misinformation is critical for public health response, as misinformation confined to a small, isolated community…
An adaptation of InfoMap to absorbing random walks using absorption-scaled graphs
Esteban Vargas Bernal, Mason A. Porter, Joseph H. Tien
InfoMap is a popular approach to detect densely connected "communities" of nodes in networks. To detect such communities, InfoMap uses random walks and ideas from information theor…
Relating Eulerian and Lagrangian spatial models for vector-host diseases dynamics through a fundamental matrix
Esteban Vargas Bernal, Omar Saucedo, Joseph Hua Tien
We explore the relationship between Eulerian and Lagrangian approaches for modeling movement in vector-borne diseases for discrete space. In the Eulerian approach we account for th…
Online reactions to the 2017 'Unite the Right' rally in Charlottesville: Measuring polarization in Twitter networks using media followership
Joseph H. Tien, Marisa C. Eisenberg, Sarah T. Cherng +1
We study the Twitter conversation following the August 2017 `Unite the Right' rally in Charlottesville, Virginia, using tools from network analysis and data science. We use media f…
Model distinguishability and inference robustness in mechanisms of cholera transmission and loss of immunity
Elizabeth C. Lee, Michael R. Kelly, Brad M. Ochocki +4
Mathematical models of cholera and waterborne disease vary widely in their structures, in terms of transmission pathways, loss of immunity, and other features. These differences ma…
The large graph limit of a stochastic epidemic model on a dynamic multilayer network
Karly A. Jacobsen, Mark G. Burch, Joseph H. Tien +1
We consider an SIR-type (Susceptible Infected Recovered) stochastic epidemic process with multiple modes of transmission on a contact network. The network is given by a…
Network-Based Analysis of a Small Ebola Outbreak
Mark G. Burch, Karly A. Jacobsen, Joseph H. Tien +1
We present a method for estimating epidemic parameters in network-based stochastic epidemic models when the total number of infections is assumed to be small. We illustrate the met…
