    Harnois, Violette; Smith, Helen C.M.; Benjamins, Steven; Johanning, Lars (Elsevier, 2015-09)
    This paper defines a methodology to compare different offshore renewable energy (ORE) mooring configurations in terms of the risk of entanglement they present to marine megafauna. Currently, the entanglement of large marine ...

    The Early Jurassic was marked by multiple periods of major global climatic and palaeoceanographic change, biotic turnover and perturbed global geochemical cycles, commonly linked to large igneous province volcanism. This ...
  • Asymmetric dot dimers – optical properties and interactions 

    Meinzer, Nina; Humphrey, Alastair D.; Barnes, William L. (2015-01-06)
    We present a study of the rich optical behaviour of the dark (grey) modes exhibited by asymmetric dot dimers and how this behaviour is modified upon interaction between dimers.
  • Asymmetry of magnetosheath flows and magnetopause shape during low Alfven Mach number solar wind

    Previous works have emphasized the significant influence of the solar wind Alfvén Mach number (MA) on magnetospheric dynamics. Here we report statistical, observational results that pertain to changes in the magnetosheath ...
  • Asymmetry of spin wave dispersions in a hexagonal magnonic crystal 

    Montoncello, F; Tacchi, S; Giovannini, L; Madami, M; Gubbiotti, G; Carlotti, G; Sirotkin, E; Ahmad, E; Ogrin, FY; Kruglyak, VV (American Institute of Physics (AIP), 2013-05-24)
    We report a study of the dispersion of spin waves in a hexagonal array of interacting ferromagnetic nanodisks for two orthogonal orientations of the in-plane applied magnetic field, i.e., either parallel or perpendicular ...
  • Asymptotic analysis and analytical solutions of a model of cardiac excitation. 

    Biktashev, V. N.; Suckley, R.; Elkin, Y. E.; Simitev, R. D. (Springer Verlag, 2008)
    We describe an asymptotic approach to gated ionic models of single-cell cardiac excitability. It has a form essentially different from the Tikhonov fast-slow form assumed in standard asymptotic reductions of excitable ...
  • Asymptotic and numerical solutions of the initial value problem in rotating planetary fluid cores 

    Liao, X.; Zhang, Keke (Oxford University Press / Royal Astronomical Society, 2010)
    An initial state of fluid motion in planetary cores or atmospheres, excited, for example, by the giant impact of an asteroid or an earthquake and then damped by viscous dissipation, decays towards the state of rigid-body ...
  • An asymptotic parallel-in-time method for highly oscillatory PDEs 

    Haut, Terry; Wingate, Beth (Society for Industrial and Applied Mathematics, 2013-03-26)
    We present a new time-stepping algorithm for nonlinear PDEs that exhibit scale separation in time. Our scheme combines asymptotic techniques (which are inexpensive but can have insufficient accuracy) with parallel-in-time ...
