Scarlet Fever Dynamics in 19th and 20th Century London

Kevin H. Zhao, David J. D. Earn

Weekly scarlet fever (SF) mortality records for London, UK, from 1842 to 1939, together with notified case records from 1901 to 1939, reveal a strong annual epidemic pattern with p…

Jointly estimating transmissibility and prior immunity from epidemic time series

David J. D. Earn, Todd L. Parsons

Infectious disease time series are often used to estimate a pathogen's basic reproduction number, . However, fits of epidemic models to time series conflate pathogen transmiss…

Global stability of epidemic models with uniform susceptibility

David J. D. Earn, C. Connell McCluskey

Transmission dynamics of infectious diseases are often studied using compartmental mathematical models, which are commonly represented as systems of autonomous ordinary differentia…

Epidemic "momentum" and a conservation law for infectious disease dynamics

David J. D. Earn, Todd L. Parsons

Infectious disease outbreaks have precipitated a profusion of mathematical models. Epidemic curves predicted by these models are typically qualitatively similar, despite distinct m…

Toward a comprehensive system for constructing compartmental epidemic models

Darren Flynn-Primrose, Steven C. Walker, Michael Li +3

Compartmental models are valuable tools for investigating infectious diseases. Researchers building such models typically begin with a simple structure where compartments correspon…

Evaluating undercounts in epidemics: response to Maruotti et al. 2022

Michael Li, Jonathan Dushoff, David J. D. Earn +1

Maruotti et al. 2022 used a mark-recapture approach to estimate bounds on the true number of monkeypox infections in various countries. These approaches are fundamentally flawed; i…

Testing and Isolation Efficacy: Insights from a Simple Epidemic Model

Ali Gharouni, F. M. Abdelmalek, David J. D. Earn +2

Testing individuals for pathogens can affect the spread of epidemics. Understanding how individual-level processes of sampling and reporting test results can affect community- or p…

Invariant predictions of epidemic patterns from radically different forms of seasonal forcing

Irena Papst, David J. D. Earn

Seasonal variation in environmental variables, and in rates of contact among individuals, are fundamental drivers of infectious disease dynamics. Unlike most periodically-forced ph…

Early Real-time Estimation of Infectious Disease Reproduction Number

Bahman Davoudi, Babak Pourbohloul, Joel Miller +3

When an infectious disease strikes a population, the number of newly reported cases is often the only available information that one can obtain during early stages of the outbreak.…

Potential-Density Basis Sets for Galactic Disks

David J. D. Earn

A class of complete potential-density basis sets in cylindrical (R,phi,z) coordinates is presented. This class is suitable for stability studies of galactic disks in three dimensio…

Symplectic Integration without Roundoff Error

David JD Earn

Most numerical integration algorithms are not designed specifically for Hamiltonian systems and do not respect their characteristic properties, which include the preservation of ph…
