  • The competitive nature of STAT complex formation drives phenotype switching of T cells 

    Sadreev, II; Chen, MZQ; Umezawa, Y; Biktashev, VN; Kemper, C; Salakhieva, DV; Welsh, GI; Kotov, NV (arXiv.org, 2017)
    Signal transducers and activators of transcription (STATs) are key molecular determinants of T cell fate and effector function. A number of inflammatory diseases are characterized by an altered balance of T cell phenotypes ...
  • Filament tension and phase-locked drift of meandering scroll waves 

    Dierckx, H; Biktasheva, IV; Verschelde, H; Panfilov, AV; Biktashev, VN (arXiv.org, 2017)
    Rotating scroll waves are self-organising patterns which are found in many oscillating or excitable systems. Here we show that quasi-periodic (meandering) scroll waves, which include the rotors that organise cardiac ...
  • Mechanisms of vortices termination in the cardiac muscle 

    Hornung, D; Biktashev, VN; Otani, NF; Shajahan, TK; Baig, T; Berg, S; Han, S; Krinsky, VI; Luther, S (Royal Society, 2017)
    We propose a solution to a long standing problem: how to terminate multiple vortices in the heart, when the locations of their cores and their critical time windows are unknown. We scan the phases of all pinned vortices ...
  • The paradox of the plankton: Species competition and nutrient feedback sustain phytoplankton diversity 

    Kenitz, K; Williams, RG; Sharples, J; Selsil, O; Biktashev, VN (Inter Research, 2013-09-17)
    The diversity of phytoplankton species and their relationship to nutrient resources are examined using a coupled phytoplankton and nutrient model for a well-mixed box. The phytoplankton community either reaches a competitive ...
  • Quasisolitons in self-diffusive excitable systems, or Why asymmetric diffusivity obeys the Second Law 

    Biktashev, VN; Tsyganov, MA (arXiv.org, 2016-07-07)
    Quasi-solitons are waves in excitable systems that reflect from boundaries and pass through each other, similarly to solitons in conservative systems. Previously, they have been observed at finely tuned parameters or in ...
  • Strength-duration relationship in an excitable medium 

    Bezekci, B; Biktashev, VN (arXiv.org, 2016)
    We consider the strength-duration relationship in one-dimensional spatially extended excitable media. In a previous study~\cite{idris2008analytical} set out to separate initial (or boundary) conditions leading to propagation ...
