Vaccination strategies and backward bifurcation in age-since-infection structured model
(Elsevier, 2002)
We consider models for a disease with acute and chronic infective stages, and variable infectivity
and recovery rates, within the context of a vaccination campaign. Models for SIRS and SIS
disease cycles exhibit backward ...
Estimating contact process saturation in sylvatic transmission of Trypanosoma cruzi in the United States
(Public Library of Science, 2010-04)
Although it has been known for nearly a century that strains of Trypanosoma cruzi, the etiological agent for Chagas' disease, are enzootic in the southern U.S., much remains unknown about the dynamics of its transmission ...
The role of adaptations in two-strain competition for sylvatic Trypanosoma cruzi transmission
(Taylor and Francis Online, 2012-08)
This study presents a continuous-time model for the sylvatic transmission dynamics of two strains of Trypanosoma cruzi enzootic in North America, in order to study the role that adaptations of each strain to distinct modes ...
Community resilience in collaborative learning
(American Institute of Mathematical Sciences, 2010-07)
This paper introduces a simplified dynamical systems framework for the study of the mechanisms behind the growth of cooperative learning in large communities. We begin from the simplifying assumption that individual-based ...
The impact of vaccination and boinfection on HPV and cervical cancer
(American Institute of Mathematical Sciences, 2009-09)
Understanding the relationship between coinfection with multiple strains of human papillomavirus and cervical cancer may play a key role in vaccination strategies for the virus. In this article we formulate a model with ...
Metering effects in population systems
(American Institute of Mathematical Sciences, 2013)
This study compares the effects of two types of metering (periodic resetting and periodic increments) on one variable in a dynamical system, relative to the behavior of the corresponding system with an equivalent level of ...
Model parameters and outbreak control for SARS
(Centers for Disease Control and Prevention, 2004-07)
Control of the 2002–2003 severe acute respiratory
syndrome (SARS) outbreak was based on rapid diagnosis
coupled with effective patient isolation. We used uncertainty
and sensitivity analysis of the basic reproductive ...
Transmission dynamics and underreporting of Kala-azar in the Indian State of Bihar
(2010)
"Kala-azar" (or Indian Visceral Leishmaniasis) is a vector-borne infectious dis-
ease affecting communities in tropical and subtropical areas of the world. Bihar,
a state in India, has one of the highest prevalence and ...
Evaluating treatment of Hepatitis C for hemolytic anemia management
(Elsevier, 2010)
The combination therapy of antiviral peg-interferon and ribavirin has evolved as one of the better treatments for Hepatitis-C. In spite of its success in controlling Hepatitis-C infection, it has also been associated with ...
Sociological phenomena as multiple nonlinearities: MTBI's new metaphor for complex human interactions
(American Institute of Mathematical Sciences, 2013)
Mathematical models are well-established as metaphors for biological and epidemiological systems. The framework of epidemic modeling has also been applied to sociological phenomena driven by peer pressure, notably in two ...
