  • Classification framework for partially observed dynamical systems 

    Shen, Y; Tino, P; Tsaneva-Atanasova, KT (American Physical Society, 2017)
    We present a general framework for classifying partially observed dynamical systems based on the idea of learning in the model space. In contrast to the existing approaches using model point estimates to represent ...

  • Generalised additive point process models for natural hazard occurrence 

    Youngman, BD; Economou, T (Wiley, 2017)
    Point processes are a natural class of model for representing occurrences of various types of natural hazard event. Flexibly implementing such models is often hindered by intractable likelihood forms. Consequently, rates ...

    The mirror game has been recently proposed as a simple, yet powerful paradigm for studying interpersonal interactions. It has been suggested that a virtual partner able to play the game with human subjects can be an ...
  • Isoform switching facilitates period control in the Neurospora crassa circadian clock 

    Akman, OE; Locke, JCW; Tang, S; Carré, I; Millar, AJ; Rand, DA (Nature Publishing Group, 2008)
    A striking and defining feature of circadian clocks is the small variation in period over a physiological range of temperatures. This is referred to as temperature compensation, although recent work has suggested that the ...
  • Mechanisms of vortices termination in the cardiac muscle 

    Hornung, D; Biktashev, VN; Otani, NF; Shajahan, TK; Baig, T; Berg, S; Han, S; Krinsky, V; Luther, S (, 2017-02-15)
    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 ...
