  • An Analytical Model for On-chip Interconnects in Multimedia Embedded Systems 

    Wu, Yulei; Min, Geyong; Zhu, Dakai; Yang, Laurence T. (Association for Computing Machinery (ACM), 2013)
    The traffic pattern has significant impact on the performance of network-on-chip. Many recent studies have shown that multimedia applications can be supported in on-chip interconnects. Driven by the motivation of evaluating ...
  • Anisotropic properties of riddled basins 

    Ashwin, Peter; Breakspear, Michael (Elsevier, 2001)
    We consider some general properties of chaotic attractors with riddled basins of attraction (basins with positive measure but open dense complements) in dynamical systems with symmetries. We investigate how a basin of ...
  • Anisotropic small-scale constraints on energy in rotating stratified turbulence 

    Kurien, Susan; Wingate, Beth; Taylor, Mark (European Physical Society, 2008-10)
    Rapidly rotating, stably stratified three-dimensional inviscid flows conserve both energy and potential enstrophy. We show that in such flows, the forward cascade of potential enstrophy imposes anisotropic constraints on ...

  • Anti-windup for a class of partially linearisable non-linear systems with application to wave energy converter control 

    Lekka, A; Turner, MC; Menon, PP (Institution of Engineering and Technology (IET), 2016-08-24)
    This paper studies the anti-windup (AW) problem for a certain class of non-linear systems, in which the plant is globally quadratically stable and also partially linearisable by a suitably chosen non-linear feedback control ...
  • The antigenic evolution of influenza: drift or thrift? 

    Wikramaratna, Paul S.; Sandeman, Michi; Recker, Mario; Gupta, Sunetra (The Royal Society, 2013-03-19)
    It is commonly assumed that antibody responses against the influenza virus are polarized in the following manner: strong antibody responses are directed at highly variable antigenic epitopes, which consequently undergo ...
  • The antigenic switching network of Plasmodium falciparum and its implications for the immuno-epidemiology of malaria 

    Noble, Robert; Christodoulou, Zóe; Kyes, Sue; Pinches, Robert; Newbold, Chris I.; Recker, Mario (eLife Sciences Publications, 2013)
    Antigenic variation in the human malaria parasite Plasmodium falciparum involves sequential and mutually exclusive expression of members of the var multi-gene family and appears to follow a non-random pattern. In this ...
  • Antigenic variation in Plasmodium falciparum malaria involves a highly structured switching pattern 

    Recker, M; Buckee, CO; Serazin, A; Kyes, S; Pinches, R; Christodoulou, Z; Springer, AL; Gupta, S; Newbold, CI (Public Library of Science, 2011-03-03)
    Many pathogenic bacteria, fungi, and protozoa achieve chronic infection through an immune evasion strategy known as antigenic variation. In the human malaria parasite Plasmodium falciparum, this involves transcriptional ...
  • Applications of machine learning in animal behaviour studies 

    Valletta, J; Torney, C; Kings, M; Thornton, A; Madden, J (Elsevier Masson, 2017-01-23)
    In many areas of animal behaviour research, improvements in our ability to collect large and detailed data sets are outstripping our ability to analyse them. These diverse, complex and often high-dimensional data sets ...
  • Approximate Bayesian Computation and simulation-based inference for complex stochastic epidemic models 

    McKinley, TJ; Vernon, I; Andrianakis, I; McCreesh, N; Oakley, JE; Nsubuga, RN; Goldstein, M; White, RG (Institute of Mathematical Statistics (IMS), 2018-02-02)
    Approximate Bayesian Computation (ABC) and other simulation-based inference methods are becoming increasingly used for inference in complex systems, due to their relative ease-of-implementation. We briefly review some of ...
  • AppTCP: The design and evaluation of application-based TCP for e-VLBI in fast long distance networks 

    Wang, G; Wu, Y; Dou, K; Ren, Y; Li, J (Elsevier, 2014-10)
    Electric Very Long Baseline Interferometry (e-VLBI) is a typical astronomical interferometry used in radio astronomy. It allows observations of an object that are made simultaneously by many radio telescopes to be combined, ...
  • Arctic amplification decreases temperature variance in Northern mid- to high-latitudes 

    Screen, James A. (Nature Publishing Group, 2014)
    Changes in climate variability are arguably more important for society and ecosystems than changes in mean climate, especially if they translate into altered extremes [1, 2, 3]. There is a common perception and growing ...

  • Are changes in global precipitation constrained by the tropospheric energy budget? 

    Lambert, F. Hugo; Allen, Myles R. (American Meteorological Society, 2009)
    A tropospheric energy budget argument is used to analyze twentieth-century precipitation changes. It is found that global and ocean-mean general circulation model (GCM) precipitation changes can be understood as being due ...
  • Are large submarine landslides temporally random or do uncertainties in available age constraints make it impossible to tell?

    © 2015. Large (>1km3) submarine landslides can potentially generate very destructive tsunamis and damage expensive sea floor infrastructure. It is therefore important to understand their frequency and triggers, and whether ...
