  • Early-warning indicators for rate-induced tipping 

    Ritchie, P; Sieber, J (AIP Publishing, 2016-09)
    A dynamical system is said to undergo rate-induced tipping when it fails to track its quasi-equilibrium state due to an above-critical-rate change of system parameters. We study a prototypical model for rate-induced tipping, ...

  • The effect of two distinct fast time scales in the rotating stratified Boussinesq equations 

    Whitehead, JP; Haut, T; Wingate, B (Springer Verlag, 2018-08-02)
    Inspired by the use of fast singular limits in time-parallel numerical methods for a single fast frequency, we consider the limiting, nonlinear dynamics for a system of partial differential equations when two ...
  • Effective diffusion of scalar fields in a chaotic flow 

    Turner, M. R.; Gilbert, Andrew D.; Thuburn, John (American Institute of Physics, 2008)
    The advection of a tracer field in a fluid flow can create complex scalar structures and increase the effect of weak diffusion by orders of magnitude. One tool to quantify this is to measure the flux of scalar across contour ...
  • The effects of a partitioned var gene repertoire of Plasmodium falciparum on antigenic diversity and the acquisition of clinical immunity 

    Recker, M; Arinaminpathy, N; Buckee, CO (BioMed Central, 2008-01-23)
    BACKGROUND: The human malaria parasite Plasmodium falciparum exploits antigenic diversity and within-host antigenic variation to evade the host's immune system. Of particular importance are the highly polymorphic var genes ...
