A Computer Simulation Study of Anatomy Induced Drift of Spiral Waves in the Human Atrium
(Hindawi Publishing Corporation, 2014)The interaction of spiral waves of excitation with atrial anatomy remains unclear. This simulation study isolates the role of atrial anatomical structures on spiral wave spontaneous drift in the human atrium. We implemented ... 
Computing with confidence: a Bayesian approach
(2006)Bayes’ rule is introduced as a coherent strategy for multiple recomputations of classifier system output, and thus as a basis for assessing the uncertainty associated with a particular system results  i.e. a basis for ... 
Concise stability conditions for systems with static nonlinear feedback expressed by a quadratic program
(Institution of Engineering and Technology (IET), 2008)The stability of the feedback connection of a strictly proper linear timeinvariant stable system with a static nonlinearity expressed by a convex quadratic program (QP) is considered. From the KarushKuhnTucker conditions ... 
Conditions for propagation and block of excitation in an asymptotic model of atrial tissue.
(2006)Detailed ionic models of cardiac cells are difficult for numerical simulations because they consist of a large number of equations and contain small parameters. The presence of small parameters, however, may be used for ... 
Conditions for sinktosource transitions and runaway feedbacks from the land carbon cycle
(Cambridge University Press, 200602)The first GCM climatecarbon cycle simulation indicated that the land biosphere could provide a significant acceleration of 21st century climate change (Cox et al. 2000). In this numerical experiment the carbon storage was ... 
Cone exchange transformations and boundedness of orbits
(Cambridge University Press, 2010)We introduce a class of twodimensional piecewise isometries on the plane that we refer to as cone exchange transformations (CETs). These are generalizations of interval exchange transformations (IETs) to 2D unbounded ... 
Confidence in Classification: A Bayesian Approach
(Springer Verlag, 2006)Bayesian classification is currently of considerable interest. It provides a strategy for eliminating the uncertainty associated with a particular choice of classifiermodel parameters, and is the optimal decisiontheoretic ... 
Confident interpretation of Bayesian decision tree ensembles for clinical applications
(Institute of Electrical and Electronics Engineers (IEEE), 2007)Bayesian averaging (BA) over ensembles of decision models allows evaluation of the uncertainty of decisions that is of crucial importance for safetycritical applications such as medical diagnostics. The interpretability ... 
A conjecture of Stanley on alternating permutations
(Electronic Journal of Combinatorics, 2007)We give two simple proofs of a conjecture of Richard Stanley concerning the equidistribution of derangements and alternating permutations with the maximal number of fixed points. 
Conoscopic observation of director reorientation during Poiseuille flow of a nematic liquid crystal
(American Institute of Physics, 2009)Director reorientation under pressure driven (Poiseuille) flow is observed conoscopically for the liquid crystal 5CB aligned at an azimuthal angle of 45° to the direction of flow. A polyimide surface treatment (AL 1254) ... 
The conservation value of abandoned pits and quarries in Cornwall: a report of the conference held at County Hall, Truro on 22nd March 1999
(The Historic Environment Service, Cornwall County Council, 2002) 
Consistency of certain constitutive relations with quantum electromagnetism
(American Physical Society, 2011)Recent work by Philbin [ New J. Phys. 12 123008 (2010)] has provided a Lagrangian theory that establishes a general method for the canonical quantization of the electromagnetic field in any dispersive, lossy, linear ... 
Constructing constrainedversion of magic squares using selection hyperheuristics
(Oxford University Press for BCS, The Chartered Institute for IT, 2014)A square matrix of distinct numbers in which every row, column and both diagonals have the same total is referred to as a magic square. Constructing a magic square of a given order is considered a difficult computational ... 
Contextdependent interaction leads to emergent search behavior in social aggregates
(National Academy of Sciences, 2009)Locating the source of an advected chemical signal is a common challenge facing many living organisms. When the advecting medium is characterized by either high Reynolds number or high Peclet number, the task becomes highly ... 
Continuous evolution of the inplane magnetic anisotropies with thickness in epitaxial Fe films
(American Institute of Physics, 1996)We have studied the evolution of the magnetic in‐plane anisotropy in epitaxial Fe/GaAs films of both (001) and (110) orientation as a function of the Fe layer thickness using the longitudinal magneto‐optic Kerr effect and ... 
Continuous TraitBased Particle Swarm Optimisation (CTBPSO)
(Springer Verlag, 2012)In natural flocks, individuals are often of the same species, but there exists considerable variation in the traits possessed by each individual. In much the same way as humans display varied levels of aggression, ... 
Control of scrollwave turbulence using resonant perturbations
(American Physical Society, 2008)Turbulence of scroll waves is a sort of spatiotemporal chaos that exists in threedimensional excitable media. Cardiac tissue and the BelousovZhabotinsky reaction are examples of such media. In cardiac tissue, chaotic ... 
Control of the stop band of an acoustic double fishnet
(Journal of the Acoustical Society of America, 2013)The acoustic transmittance of two closely spaced solid plates, each perforated with a square array of cylindrical holes, exhibits a band of nearperfect acoustic attenuation originating from hybridization between a resonance ... 
Control of Transient Power during Unintentional Islanding of Microgrids
(IEEE, 2014)In inverterbased microgrids, the paralleled inverters need to work in gridconnected mode and standalone mode and to transfer seamlessly between the two modes. In gridconnected mode, the inverters control the amount of ...
