  • Coprime invariable generation and minimal-exponent groups 

    Detomi, Eloisa; Lucchini, Andrea; Roney-Dougal, C.M. (2015-08) - Journal article
    A finite group G is coprimely invariably generated if there exists a set of generators {g1,. .,gu} of G with the property that the orders |g1|,. .,|gu| are pairwise coprime and that for all x1,. .,xu∈G the set {g1x1,. ...
  • Copulae on products of compact Riemannian manifolds 

    Jupp, P.E. (2015-09) - Journal article
    Abstract One standard way of considering a probability distribution on the unit n -cube, [0 , 1]n , due to Sklar (1959), is to decompose it into its marginal distributions and a copula, i.e. a probability distribution on ...
  • Counting chirps : acoustic monitoring of cryptic frogs 

    Measey, G. John; Stevenson, Ben C.; Scott, Tanya; Altwegg, Res; Borchers, David L. (2017-06) - Journal article
    1 .  Global amphibian declines have resulted in a vital need for monitoring programmes that follow population trends. Monitoring using advertisement calls is ideal as choruses are undisturbed during data collection. However, ...
  • Coupled bulk-surface free boundary problems arising from a mathematical model of receptor-ligand dynamics 

    Elliot, Charles M.; Ranner, Thomas; Venkataraman, Chandrasekhar (2017-02-08) - Journal article
    We consider a coupled bulk-surface system of partial differential equations with nonlinear coupling modelling receptor-ligand dynamics. The model arises as a simplification of a mathematical model for the reaction between ...
  • The critical merger distance between two co-rotating quasi-geostrophic vortices 

    Reinaud, Jean Noel; Dritschel, David Gerard (2005-01-10) - Journal article
    This paper examines the critical merger or strong interaction distance between two equal-potential-vorticity quasi-geostrophic vortices. The interaction between the two vortices depends on five parameters: their volume ...
  • A critical review of the literature on population modelling 

    Cabrelli, Abigail; Harwood, John; Matthiopoulos, Jason; New, Leslie Frances; Thomas, Len (University of St Andrews, 2009) - Report
    The 2005 report of the National Research Council’s ‘Committee on Characterizing Biologically Significant Marine Mammal Behavior’ proposed a framework, which they called PCAD - Population Consequences of Acoustic Disturbance, ...
  • Decision problems for word-hyperbolic semigroups 

    Cain, Alan James; Pfeiffer, Markus Johannes (2016-07-22) - Journal article
    This paper studies decision problems for semigroups that are word-hyperbolic in the sense of Duncan & Gilman. A fundamental investigation reveals that the natural definition of a `word-hyperbolic structure' has to be ...
  • Decomposition tables for experiments : I. A chain of randomizations 

    Brien, C. J.; Bailey, Rosemary Anne (2009-12) - Journal article
    One aspect of evaluating the design for an experiment is the discovery of the relationships between subspaces of the data space. Initially we establish the notation and methods for evaluating an experiment with a single ...
  • Decomposition tables for experiments : II. Two–one randomizations 

    Brien, C. J.; Bailey, Rosemary Anne (2010-10) - Journal article
    We investigate structure for pairs of randomizations that do not follow each other in a chain. These are unrandomized-inclusive, independent, coincident or double randomizations. This involves taking several structures ...
  • The DeepMIP contribution to PMIP4 : experimental design for model simulations of the EECO, PETM, and pre-PETM (version 1.0) 

    Lunt, Daniel J.; Huber, Matthew; Anagnostou, Eleni; Baatsen, Michiel L. J.; Caballero, Rodrigo; DeConto, Rob; Dijkstra, Henk A.; Donnadieu, Yannick; Evans, David; Feng, Ran; Foster, Gavin L.; Gasson, Ed; Von Der Heydt, Anna S.; Hollis, Chris J.; Inglis, Gordon N.; Jones, Stephen M.; Kiehl, Jeff; Turner, Sandy Kirtland; Korty, Robert L.; Kozdon, Reinhardt; Krishnan, Srinath; Ladant, Jean Baptiste; Langebroek, Petra; Lear, Caroline H.; LeGrande, Allegra N.; Littler, Kate; Markwick, Paul; Otto-Bliesner, Bette; Pearson, Paul; Poulsen, Christopher J.; Salzmann, Ulrich; Shields, Christine; Snell, Kathryn; Stärz, Michael; Super, James; Tabor, Clay; Tierney, Jessica E.; Tourte, Gregory J. L.; Tripati, Aradhna; Upchurch, Garland R.; Wade, Bridget S.; Wing, Scott L.; Winguth, Arne M. E.; Wright, Nicky M.; Zachos, James C.; Zeebe, Richard E. (2017-02-23) - Journal article
    Past warm periods provide an opportunity to evaluate climate models under extreme forcing scenarios, in particular high (> 800ppmv) atmospheric CO2 concentrations. Although a post hoc intercomparison of Eocene (∼ 50 Ma) ...
  • A default prior distribution for contingency tables with dependent factor levels 

    Overstall, Antony; King, Ruth (2014-01) - Journal article
    A default prior distribution is proposed for the Bayesian analysis of contingency tables. The prior is specified to allow for dependence between levels of the factors. Different dependence structures are considered, including ...
  • Density estimation and time trend analysis of large herbivores in Nagarhole, India 

    Gangadharan, Aditya (2005) - Thesis
    Density estimates for six large herbivore species were obtained through analysis of line transect data from Nagarhole National Park, south-western India, collected between 1989 and 2000. These species were Chital (Axis ...
  • The dependence of coronal loop heating on the characteristics of slow photospheric motions 

    Ritchie, M. L.; Wilmot-Smith, A. L.; Hornig, G. (2016-06-06) - Journal article
    The Parker hypothesis assumes that heating of coronal loops occurs due to reconnection, induced when photospheric motions braid field lines to the point of current sheet formation. In this contribution we address the ...
  • Depletion of nonlinearity in the pressure force driving Navier-Stokes flows : nonlinear depletion in NS flows 

    Tran, Chuong Van; Yu, Xinwei (2015-04-17) - Journal article
    The dynamics of the velocity norms ||u||Lq for q ≥ 3, in Navier-Stokes flows is studied. The pressure term that drives this dynamics has a high degree of nonlinear depletion, which owes its origin to a genuine negative ...
  • Description and seasonal detection of two potential whale calls recorded in the Indian Ocean 

    Sousa, Andreia G; Harris, Danielle (2015-09) - Journal article
    Unidentified acoustic signals are recorded by hydrophones placed in the world's oceans. Some of these sounds are suspected to originate from marine mammals. In this study, two acoustic signals recorded by two arrays at ...
  • Design and analysis of line transect surveys for primates 

    Buckland, Stephen Terrence; Plumptre, A J; Thomas, Len; Rexstad, Eric A (2010-10) - Journal article
    Line transect surveys are widely used for estimating abundance of primate populations. The method relies on a small number of key assumptions, and if these are not met, substantial bias may occur. For a variety of reasons, ...
  • Diffusion driven oscillations in gene regulatory networks 

    Macnamara, Cicely Krystyna; Chaplain, Mark Andrew Joseph (2016-10-21) - Journal article
    Gene regulatory networks (GRNs) play an important role in maintaining cellular function by correctly timing key processes such as cell division and apoptosis. GRNs are known to contain similar structural components, which ...
  • Digit frequencies and Bernoulli convolutions 

    Kempton, Thomas Michael William (2014-06-27) - Journal article
    It is well known that when β is a Pisot number, the corresponding Bernoulli convolution ν(β) has Hausdorff dimension less than 1, i.e. that there exists a set A(β) with (ν(β))(A(β))=1 and dim_H(A(β))<1. We show explicitly ...
  • Dimension and measure for generic continuous images 

    Balka, Richard; Farkas, Abel; Fraser, Jonathan M.; Hyde, James T. (2013) - Journal article
    We consider the Banach space consisting of continuous functions from an arbitrary uncountable compact metric space, X, into R-n. The key question is 'what is the generic dimension of f(X)?' and we consider two different ...
  • Dimension conservation for self-similar sets and fractal percolation 

    Falconer, Kenneth John; Jin, Xiong (2015) - Journal article
    We introduce a technique that uses projection properties of fractal percolation to establish dimension conservation results for sections of deterministic self-similar sets. For example, let K be a self-similar subset of ...
