Aging affects circadian clock and metabolism and modulates timing of medication
(Elsevier, 2021-04)Aging is associated with impairments in the circadian rhythms, and with energy deregulation that affects multiple metabolic pathways. The goal of this study is to unravel the complex interactions among aging, metabolism, ... -
Analysis of a pressure-robust hybridized discontinuous Galerkin method for the stationary Navier-Stokes equations
(Springer, 2019-08-30)We present well-posedness and an a priori error analysis of the hybridized discontinuous Galerkin method for the stationary form of the Navier-Stokes problem proposed in (J Sci Comput, 76(3):1484{ 1501, 2018). This scheme ... -
An Anisotropic Subgrid-Scale Parameterization for Large-Eddy Simulations of Stratified Turbulence
(AMS, 2020-10-01)Subgrid-scale (SGS) parameterizations in atmosphere and ocean models are often defined independently in the horizontal and vertical directions because the grid spacing is not the same in these directions (anisotropic ... -
An Antibiotic Protocol To Minimize Emergence Of Drug-Resistant Tuberculosis
(Elsevier, 2014-04-15)A within-host model of the spread of tuberculosis is proposed here where the emergence of drug resistance and bacterial dormancy are simultaneously combined. We consider both sensitive and resistant strains of tuberculosis ... -
Backscatter in stratified turbulence
(Elsevier, 2016-11)In this paper, kinetic and potential energy transfers around a spectral test fil ter scale in direct numerical simulations of decaying stratified turbulence are studied in both physical and spectral domains. It is shown ... -
Best response dynamics improve sustainability and equity outcomes in common-pool resources problems, compared to imitation dynamics
(Journal of Theoretical Biology, 2021-01-21)Shared resource extraction among profit-seeking individuals involves a tension between individual benefit and the collective well-being represented by the persistence of the resource. Many game theoretic models explore ... -
Bifurcation analysis and application for impulsive systems with delayed impulses
(World Scientific, 2017-11)In this article, we present a systematic approach to bifurcation analysis of impulsive systems with autonomous or periodic right-hand sides that may exhibit delayed impulse terms. Methods include Lyapunov–Schmidt reduction ... -
Bifurcation of Bounded Solutions of Impulsive Differential Equations
(World Scientific Publishing, 2016-12-30)In this article, we examine nonautonomous bifurcation patterns in nonlinear systems of impulsive differential equations. The approach is based on Lyapunov–Schmidt reduction applied to the linearization of a particular ... -
Bounded Rationality Alters The Dynamics Of Paediatric Immunization Acceptance
(Nature Publishing Group, 2015-06-02)Interactions between disease dynamics and vaccinating behavior have been explored in many coupled behavior-disease models. Cognitive effects such as risk perception, framing, and subjective probabilities of adverse events ... -
Carrot Or Stick? Modelling How Landowner Behavioural Responses Can Cause Incentive-Based Forest Governance To Backfire
(Public Library of Science, 2013-10-30)Mitigating the negative impacts of declining worldwide forest cover remains a significant socio-ecological challenge, due to the dominant role of human decision-making. Here we use a Markov chain model of land-use dynamics ... -
Characteristics of quasistationary near-wall turbulence subjected to strong stable stratification in open-channel flows
(American Physical Society, 2020-06-05)Characteristics of near-wall turbulence at quasistationarity under strong wall cooling are studied using direct numerical simulation of open-channel flow. It is shown that if turbulence reaches quasistationarity, then the ... -
Coevolution Of Risk Perception, Sexual Behaviour, And Hiv Transmission In An Agent-Based Model
(Elsevier, 2013-11-21)Risk perception shapes individual behaviour, and is in turn shaped by the consequences of that behaviour. Here we explore this dynamics in the context of human immunodeficiency virus (HIV) spread. We construct a simplified ... -
Comparing malaria surveillance with periodic spraying in the presence of insecticide-resistant mosquitoes: Should we spray regularly or based on human infections?
(Elsevier, 2016-06-01)There is an urgent need for more understanding of the effects of surveillance on malaria control. Indoor residual spraying has had beneficial effects on global malaria reduction, but resistance to the insecticide poses a ... -
Competition Between Injunctive Social Norms And Conservation Priorities Gives Rise To Complex Dynamics In A Model Of Forest Growth And Opinion Dynamics
(Elsevier, 2017-11-07)Human and environmental systems are often treated as existing in isolation from one another, whereas in fact they are often two parts of a single, coupled human-environment system. Developing theoretical models of coupled ... -
Continuous approximation of linear impulsive systems and a new form of robust stability
(Elsevier, 2018-01-01)The time-scale tolerance for linear ordinary impulsive differential equations is introduced. How large the time-scale tolerance is directly reflects the degree to which the qualitative dynamics of the linear impulsive ... -
Control of the Landau–Lifshitz equation
(Elsevier, 2016-05)The Landau–Lifshitz equation describes the dynamics of magnetization inside a ferromagnet. This equation is nonlinear and has an infinite number of stable equilibria. It is desirable to control the system from one equilibrium ... -
Convective flow reversal in self-powered enzyme micropumps
(Proceedings of the National Academy of Sciences, 2016-02-22)Surface-bound enzymes can act as pumps that drive large-scale fluid flows in the presence of their substrates or promoters. Thus, enzymatic catalysis can be harnessed for "on demand" pumping in nano-and microfluidic devices ... -
Cost-Effectiveness Evaluation Of Quadrivalent Influenza Vaccines For Seasonal Influenza Prevention: A Dynamic Modeling Study Of Canada And The United Kingdom
(BioMed Central, 2015-10-27)Background: The adoption of quadrivalent influenza vaccine (QIV) to replace trivalent influenza vaccine (TIV) in immunization programs is growing worldwide, thus helping to address the problem of influenza B lineage mismatch. ... -
Could The Human Papillomavirus Vaccines Drive Virulence Evolution?
(Royal Society, The, 2015-01-07)The human papillomavirus (HPV) vaccines hold great promise for preventing several cancers caused by HPV infections. Yet little attention has been given to whether HPV could respond evolutionarily to the new selection ... -
Coupled Human-Environment Dynamics Of Forest Pest Spread And Control In A Multi-Patch, Stochastic Setting
(Public Library of Science, 2015-10-02)Background The transportation of camp firewood infested by non-native forest pests such as Asian long-horned beetle (ALB) and emerald ash borer (EAB) has severe impacts on North American forests. Once invasive forest pests ...
