[HTML][HTML] A new world malaria map: Plasmodium falciparum endemicity in 2010

…, DL Smith, CA Guerra, IRF Elyazar, GL Johnston… - Malaria journal, 2011 - Springer
Background Transmission intensity affects almost all aspects of malaria epidemiology and
the impact of malaria on human populations. Maps of transmission intensity are necessary to …

Time delay induced death in coupled limit cycle oscillators

DVR Reddy, A Sen, GL Johnston - Physical Review Letters, 1998 - APS
We investigate the dynamical behavior of two limit cycle oscillators that interact with each
other via time delayed coupling and find that time delay can lead to amplitude death of the …

Experimental evidence of time-delay-induced death in coupled limit-cycle oscillators

DVR Reddy, A Sen, GL Johnston - Physical Review Letters, 2000 - APS
Experimental observations of time-delay-induced amplitude death in two coupled nonlinear
electronic circuits that are individually capable of exhibiting limit-cycle oscillations are …

Quantitative assessment of Plasmodium falciparum sexual development reveals potent transmission-blocking activity by methylene blue

SH Adjalley, GL Johnston, T Li… - Proceedings of the …, 2011 - National Acad Sciences
Clinical studies and mathematical models predict that, to achieve malaria elimination,
combination therapies will need to incorporate drugs that block the transmission of Plasmodium …

[HTML][HTML] Mitotic Evolution of Plasmodium falciparum Shows a Stable Core Genome but Recombination in Antigen Families

SER Bopp, MJ Manary, AT Bright, GL Johnston… - PLoS …, 2013 - journals.plos.org
Malaria parasites elude eradication attempts both within the human host and across nations.
At the individual level, parasites evade the host immune responses through antigenic …

Time delay effects on coupled limit cycle oscillators at Hopf bifurcation

DVR Reddy, A Sen, GL Johnston - Physica D: Nonlinear Phenomena, 1999 - Elsevier
We present a detailed study of the effect of time delay on the collective dynamics of coupled
limit cycle oscillators at Hopf bifurcation. For a simple model consisting of just two oscillators …

Amplitude-mediated chimera states

GC Sethia, A Sen, GL Johnston - Physical Review E, 2013 - APS
We investigate the possibility of obtaining chimera state solutions of the nonlocal complex
Ginzburg-Landau equation (NLCGLE) in the strong coupling limit when it is important to retain …

Phase-locked patterns and amplitude death in a ring of delay-coupled limit cycle oscillators

R Dodla, A Sen, GL Johnston - Physical Review E, 2004 - APS
We study the existence and stability of phase-locked patterns and amplitude death states in
a closed chain of delay coupled identical limit cycle oscillators that are near a supercritical …

Dynamics of a limit cycle oscillator under time delayed linear and nonlinear feedbacks

DVR Reddy, A Sen, GL Johnston - Physica D: Nonlinear Phenomena, 2000 - Elsevier
We study the effects of time delayed linear and nonlinear feedbacks on the dynamics of a
single Hopf bifurcation oscillator. Our numerical and analytic investigations reveal a host of …

Balancing drug resistance and growth rates via compensatory mutations in the Plasmodium falciparum chloroquine resistance transporter

I Petersen, SJ Gabryszewski, GL Johnston… - Molecular …, 2015 - Wiley Online Library
The widespread use of chloroquine to treat P lasmodium falciparum infections has resulted
in the selection and dissemination of variant haplotypes of the primary resistance …
