    Aguiar, M.; Ashwin, Peter; Dias, A.; Field, M. (Springer Verlag, 2011)
    We consider the dynamics of small networks of coupled cells. We usually assume asymmetric inputs and no global or local symmetries in the network and consider equivalence of networks in this setting; that is, when two ...

    Ashwin, Peter; Orosz, Gábor; Wordsworth, John; Townley, Stuart (Society for Industrial and Applied Mathematics, 2007)
    Systems of globally coupled phase oscillators can have robust attractors that are heteroclinic networks. We investigate such a heteroclinic network between partially synchronized states where the phases cluster into three ...

(EDP Sciences for European Southern Observatory (ESO), 2010)
    Context. An important goal within the quest for detecting an Earth-like extrasolar planet, will be to identify atmospheric gaseous bio-signatures. Aims. Observations of the light transmitted through the Earth’s atmosphere, ...
  • Economical carbon and cellulosic sheet moulding compounds for semi- and non-structural applications 

    Evans, Kenneth E.; Brookbank, Paul A.; Savage, Luke (SAGE Publications, 2015)
    The use of discontinuous carbon fibre plastics (DCFP) in automotive applications is increasing. The material offers a light weight and stiff alternative to conventional short-fibre glass-reinforced composites such as sheet ...
  • Edges of Mutually Non-dominating Sets 

    Everson, Richard M.; Walker, David J.; Fieldsend, Jonathan E. (ACM, 2013-07)
    Multi-objective optimisation yields an estimated Pareto front of mutually non-dominating solutions, but with more than three objectives understanding the relationships between solutions is challenging. Natural solutions ...
  • Effect of a Jurassic Oceanic Anoxic Event on belemnite ecology and evolution. 

    Ullmann, CV; Thibault, N; Ruhl, M; Hesselbo, Stephen P.; Korte, C (PNAS, 2014-07-15)
    The Toarcian oceanic anoxic event (T-OAE; ∼ 183 million y ago) is possibly the most extreme episode of widespread ocean oxygen deficiency in the Phanerozoic, coinciding with rapid atmospheric pCO2 increase and significant ...
  • The effect of axial load on the sagittal plane curvature of the upright human spine in vivo 

    Meakin, Judith R.; Smith, Francis W.; Gilbert, Fiona J.; Aspden, Richard M. (Elsevier, 2008)
    Determining the effect of load carriage on the human spine in vivo is important for determining spinal forces and establishing potential mechanisms of back injury. Previous studies have suggested that the natural curvature ...
