  • Biclustering models for structured microarray data 

    Turner, Heather L.; Bailey, Trevor C.; Krzanowski, Wojtek J.; Hemingway, Cheryl A. (IEEE, 2005)
    Microarrays have become a standard tool for investigating gene function and more complex microarray experiments are increasingly being conducted. For example, an experiment may involve samples from several groups or may ...
  • Bidirectional transport and pulsing states in a multi-lane ASEP model 

    Lin, Congping; Steinberg, Gero; Ashwin, Peter (IOP Publishing, 2011)
    In this paper, we introduce an ASEP-like transport model for bidirectional motion of particles on a multi-lane lattice. The model is motivated by {\em in vivo} experiments on organelle motility along a microtubule (MT), ...
  • Bifurcation Analysis of a Two-Compartment Hippocampal Pyramidal Cell Model 

    Atherton, LA; Prince, LY; Tsaneva-Atanasova, KT (Springer Verlag, 2016-05-25)
    The Pinsky-Rinzel model is a non-smooth 2-compartmental CA3 pyramidal cell model that has been used widely within the field of neuroscience. Here we propose a modified (smooth) system that captures the qualitative behaviour ...
  • Bifurcation analysis of delay-induced resonances of the El-Niño Southern Oscillation. 

    Krauskopf, Bernd; Sieber, J. (Royal Society, 2014)
    Models of global climate phenomena of low to intermediate complexity are very useful for providing an understanding at a conceptual level. An important aspect of such models is the presence of a number of feedback loops ...
  • Bifurcation to heteroclinic cycles and sensitivity in three and four coupled phase oscillators 

    Ashwin, Peter; Burylko, Oleksandr; Maistrenko, Yuri (Elsevier, 2008)
    We study the bifurcation and dynamical behaviour of the system of N globally coupled identical phase oscillators introduced by Hansel, Mato and Meunier, in the cases N=3 and N=4. This model has been found to exhibit robust ...
  • Biomass burning related ozone damage on vegetation over the Amazon forest: A model sensitivity study 

    Pacifico, F; Folberth, GA; Sitch, S; Haywood, JM; Rizzo, LV; Malavelle, FF; Artaxo, P (European Geosciences Union, 2015-03-10)
    © Author(s) 2015. The HadGEM2 earth system climate model was used to assess the impact of biomass burning on surface ozone concentrations over the Amazon forest and its impact on vegetation, under present-day climate ...
  • Bistability in feedback circuits as a byproduct of evolution of evolvability 

    Kuwahara, Hiroyuki; Soyer, Orkun S. (2012)
    Noisy bistable dynamics in gene regulation can underlie stochastic switching and is demonstrated to be beneficial under fluctuating environments. It is not known, however, if fluctuating selection alone can result in ...
  • Blowout bifurcation in a system of coupled chaotic lasers 

    Ashwin, Peter; Terry, John R.; Thornburg, K. Scott; Roy, Rajarshi (American Physical Society, 1998)
    We show that loss of synchronization of two identical coupled chaotic class B lasers can occur via a blowout bifurcation. This occurs when a transverse Lyapunov exponent governing the stability of a synchronized subspace ...
  • Bounded real and positive real balanced truncation for infinite-dimensional systems 

    Guiver, Chris; Opmeer, Mark R. (American Institute of Mathematical Sciences, 2013)
    Bounded real balanced truncation for infinite-dimensional systems is considered. This provides reduced order finite-dimensional systems that retain bounded realness. We obtain an error bound analogous to the finite-dimensional ...
  • Bounds on the dynamics of sink populations with noisy immigration 

    Eager, Eric Alan; Guiver, Chris; Hodgson, David J.; Rebarber, Richard; Stott, Iain; Townley, Stuart (Elsevier, 2014)
    Sink populations are doomed to decline to extinction in the absence of immigration. The dynamics of sink populations are not easily modelled using the standard framework of per capita rates of immigration, because numbers ...
  • Broad range of 2050 warming from an observationally constrained large climate model ensemble 

    Rowlands, Daniel J.; Frame, David J.; Ackerley, Duncan; Aina, Tolu; Booth, Ben B.B.; Christensen, Carl; Collins, Matthew; Faull, Nicholas; Forest, Chris E.; Grandey, Benjamin S.; Gryspeerdt, Edward; Highwood, Eleanor J.; Ingram, William J.; Knight, Sylvia; Lopez, Ana; Massey, Neil; McNamara, Frances; Meinshausen, Nicolai; Piani, Claudio; Rosier, Suzanne M.; Sanderson, Benjamin M.; Smith, Leonard A.; Stone, Daithi A.; hurston, Milo; Yamazaki, Kuniko; Yamazak, Y. Hiro; Allen, Myles R. (Nature Publishing Group, 2012)
    Incomplete understanding of three aspects of the climate system—equilibrium climate sensitivity, rate of ocean heat uptake and historical aerosol forcing—and the physical processes underlying them lead to uncertainties in ...
  • BSim: an agent-based tool for modeling bacterial populations in systems and synthetic biology. 

    Gorochowski, TE; Matyjaszkiewicz, Antoni; Todd, T; Oak, N; Kowalska, K; Reid, S; Tsaneva-Atanasova, Krasimira; Savery, NJ; Grierson, CS; Di Bernardo, Mario (Public Library of Science (PLoS), 2012)
    Large-scale collective behaviors such as synchronization and coordination spontaneously arise in many bacterial populations. With systems biology attempting to understand these phenomena, and synthetic biology opening up ...
  • Buckling of scroll waves 

    Dierckx, H.; Verschelde, H.; Selsil, O.; Biktashev, V. N. (American Physical Society, 2012)
    A scroll wave in a sufficiently thin layer of an excitable medium with negative filament tension can be stable nevertheless due to filament rigidity. Above a certain critical thickness of the medium, such scroll wave will ...
  • The Build-up to Eruptive Solar Events Viewed as the Development of Chiral Systems 

    Martin, Sara F.; Panasenco, Olga; Berger, M.A.; Engvold, Oddbjorn; Lin, Yong; Pevtsov, Alexei A.; Srivastava, Nandita (Astronomical Society of the Pacific, 2012)
    When we examine the chirality or observed handedness of the chromospheric and coronal structures involved in the long-term build-up to eruptive events, we find that they evolve in very specific ways to form two and only ...
  • Building a traceable climate model hierarchy with multi-level emulators 

    Giang T. Tran; Kevin I. C. Oliver; András Sóbester; David J. J. Toal; Philip B. Holden; Robert Marsh; Challenor, PG; Neil R. Edwards (Copernicus Publications, 2016-04-18)
    To study climate change on multi-millennial timescales or to explore a model's parameter space, efficient models with simplified and parameterised processes are required. However, the reduction in explicitly modelled ...
  • A Ca2+-based computational model for NMDA receptor-dependent synaptic plasticity at individual post-synaptic spines in the Hippocampus. 

    Rackham, OJ; Tsaneva-Atanasova, Krasimira; Ganesh, A; Mellor, JR (Frontiers, 2010)
    Associative synaptic plasticity is synapse specific and requires coincident activity in pre-synaptic and post-synaptic neurons to activate NMDA receptors (NMDARs). The resultant Ca(2+) influx is the critical trigger for ...
  • Calcium-Induced Calcium Release during Action Potential Firing in Developing Inner Hair Cells 

    Iosub, Radu; Avitabile, Daniele; Grant, Lisa; Tsaneva-Atanasova, Krasimira; Kennedy, Helen J. (Biophysical Society / Elsevier, 2015)
