  • Galois covers of type (p,...,p), vanishing cycles formula, and the existence of a torsor structure 

    Saidi, Mohamed; Williams, N (Osaka University, 2018-04-18)
    In this article we prove a local Riemman-Hurwitz formula which compares the dimensions of the spaces of vanishing cycles in a finite Galois cover of type (p, p, · · · , p) between formal germs of p-adic curves and which ...
  • Galois scaffolds and Galois module structure in extensions of characteristic p local fields of degree p2 

    Byott, NP (Elsevier, 2013-07-11)
    A Galois scaffold, in a Galois extension of local fields with perfect residue fields, is an adaptation of the normal basis to the valuation of the extension field, and thus can be applied to answer questions of Galois ...
  • Generalised additive point process models for natural hazard occurrence 

    Youngman, BD; Economou, T (Wiley, 2017-05-03)
    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 ...
  • Generalised trigonometric functions: Basis and regularity properties 

    Boulton, L; Melkonian, H (Elsevier, 2016-05-16)
    We examine regularity and basis properties of the family of rescaled p-cosine functions. We find sharp estimates for their Fourier coefficients. We then determine two thresholds, p0 < 2 and p1 > 2, such that this family ...
  • A generalized 2D-dynamical mean-field Ising model with a rich set of bifurcations (inspired and applied to financial crises) 

    Smug, D; Sornette, D; Ashwin, PB (World Scientific Publishing, 2018-05-07)
    We analyze an extended version of the dynamical mean-field Ising model. Instead of classical physical representation of spins and external magnetic field, the model describes traders' opinion dynamics. The external field ...
  • Generation and escape of local waves from the boundary of uncoupled cardiac tissue 

    Biktashev, V. N.; Arutunyan, A.; Sarvazyan, N. A. (Biophysical Society, 2008)
    We aim to understand the formation of abnormal waves of activity from myocardial regions with diminished cell-to-cell coupling. En route to this goal, we studied the behavior of a heterogeneous myocyte network in which a ...
  • Generic stabilisability for time-delayed feedback control 

    Sieber, Jan (Royal Society, 2016-05-04)
    Time delayed feedback control is one of the most successful methods to discover dynamically unstable features of a dynamical system in an experiment. This approach feeds back only terms that depend on the difference between ...

    Campylobacter jejuni, the most common cause of bacterial diarrhoeal disease, is normally helical. However, it can also adopt straight rod, elongated helical and coccoid forms. Studying how helical morphology is generated, ...
  • Geometric generalised Lagrangian mean theories 

    Gilbert, AD; Vanneste, J (Cambridge University Press (CUP), 2018-01-25)
    Many fluctuation-driven phenomena in fluids can be analysed effectively using the generalised Lagrangian mean (GLM) theory of Andrews & McIntyre (1978a). This finiteamplitude theory relies on particle-following averaging ...
  • Geophysical Fluid Dynamics: Whence, Whither and Why? 

    Vallis, G (Royal Society, 2016-08-24)
    This article discusses the role of Geophysical Fluid Dynamics (GFD) in understanding the natural environment, and in particular the dynamics of atmospheres and oceans on Earth and elsewhere. GFD, as usually understood, is ...
  • A geostatistical extreme-value framework for fast simulation of natural hazard events 

    Youngman, BD; Stephenson, DB (Royal Society, 2016-05)
    We develop a statistical framework for simulating natural hazard events that combines extreme value theory and geostatistics. Robust generalized additive model forms represent generalized Pareto marginal distribution ...
