Modeling complex systems: A case study of compartmental models in epidemiology
Alexander F. Siegenfeld, Pratyush K. Kollepara, Yaneer Bar-Yam
Compartmental epidemic models have been widely used for predicting the course of epidemics, from estimating the basic reproduction number to guiding intervention policies. Studies…
Shannon information criterion for low-high diversity transition in Moran and Voter models
Gabriella D. Franco, Flavia M. D. Marquitti, Lucas D. Fernandes +2
Mutation and drift play opposite roles in genetics. While mutation creates diversity, drift can cause gene variants to disappear, especially when they are rare. In the absence of n…
Eliminating COVID-19: The Impact of Travel and Timing
Alexander F. Siegenfeld, Yaneer Bar-Yam
We analyze the spread of COVID-19 by considering the transmission of the disease among individuals both within and between regions. A set of regions can be defined as any partition…
Mean Field Approximation to a Spatial Host-Pathogen Model
M. A. M. de Aguiar, E. Rauch, B. C. Stacey +1
We study the mean field approximation to a simple spatial host-pathogen model that has been shown to display interesting evolutionary properties. We show that previous derivations…
Robustness Against Extinction by Stochastic Sex Determination in Small Populations
David M. Schneider, Eduardo do Carmo, Yaneer Bar-Yam +1
Sexually reproducing populations with small number of individuals may go extinct by stochastic fluctuations in sex determination, causing all their members to become male or female…
The role of sex separation in neutral speciation
Elizabeth M. Baptestini, Marcus A. M. de Aguiar, Yaneer Bar-Yam
Neutral speciation mechanisms based on isolation by distance and sexual selection, termed topopatric, have recently been shown to describe the observed patterns of abundance distri…
