    Cargill, P.J. (2014-03-20) - Journal article
    The temperature dependence of the emission measure (EM) in the core of active regions coronal loops is an important diagnostic of heating processes. Observations indicate that EM(T) ~ T a below approximately 4 MK, with 2 < ...
  • Adventures in applying iteration lemmas 

    Pfeiffer, Markus Johannes (University of St Andrews, 2013-06-28) - Thesis
    The word problem of a finitely generated group is commonly defined to be a formal language over a finite generating set. The class of finite groups has been characterised as the class of finitely generated groups that ...
  • Analysing mark-recapture-recovery data in the presence of missing covariate data via multiple imputation 

    Worthington, Hannah; King, Ruth; Buckland, Stephen Terrence (2015-03) - Journal article
    We consider mark–recapture–recovery data with additional individual time-varying continuous covariate data. For such data it is common to specify the model parameters, and in particular the survival probabilities, as a ...
  • An approximate Bayesian method applied to estimating the trajectories of four British grey seal (Halichoerus grypus) populations from pup counts. 

    Lonergan, Michael Edward; Thompson, David; Thomas, Leonard Joseph; Duck, Callan David (2011) - Journal article
    1. For British grey seals, as with many pinniped species, population monitoring is implemented by aerial surveys of pups at breeding colonies. Scaling pup counts up to population estimates requires assumptions about ...
  • An assessment of the population of cotton-top tamarins (Saguinus oedipus) and their habitat in Colombia 

    Savage, Anne; Thomas, Len; Feilen, Katie L.; Kidney, Darren; Soto, Luis H.; Pearson, Mackenzie; Medina, Felix S.; Emeris, German; Guillen, Rosamira R. (2016-12-28) - Journal article
    Numerous animals have declining populations due to habitat loss, illegal wildlife trade, and climate change. The cotton-top tamarin (Saguinus oedipus) is a Critically Endangered primate species, endemic to northwest Colombia, ...
  • Assigning stranded bottlenose dolphins to source stocks using stable isotope ratios following the Deepwater Horizon oil spill 

    Hohn, A. A.; Thomas, L.; Carmichael, R. H.; Litz, J.; Clemons-Chevis, C.; Shippee, S. F.; Sinclair, C.; Smith, S.; Speakman, T. R.; Tumlin, M. C.; Zolman, E. S. (2017-01-31) - Journal article
    The potential for stranded dolphins to serve as a tool for monitoring free-ranging populations would be enhanced if their stocks of origin were known. We used stable isotopes of carbon, nitrogen, and sulfur from skin to ...
  • Automorphism groups of countable algebraically closed graphs and endomorphisms of the random graph 

    Dolinka, Igor; Gray, Robert Duncan; McPhee, Jillian Dawn; Mitchell, James David; Quick, Martyn (2016-05) - Journal article
    We establish links between countable algebraically closed graphs and the endomorphisms of the countable universal graph R. As a consequence we show that, for any countable graph Γ, there are uncountably many maximal subgroups ...
  • Avoidance of wind farms by harbour seals is limited to pile driving activities 

    Russell, Deborah J. F.; Hastie, Gordon D.; Thompson, David; Janik, Vincent M.; Hammond, Philip S.; Scott-Hayward, Lindesay A. S.; Matthiopoulos, Jason; Jones, Esther L.; McConnell, Bernie J. (2016-12) - Journal article
    1. As part of global efforts to reduce dependence on carbon-based energy sources there has been a rapid increase in the installation of renewable energy devices. The installation and operation of these devices can result ...
  • Backward wave cyclotron-maser emission in the auroral magnetosphere 

    Speirs, D. C.; Bingham, R.; Cairns, R. A.; Vorgul, I.; Kellett, B. J.; Phelps, A. D. R.; Ronald, K. (2014-10-07) - Journal article
    In this Letter, we present theory and particle-in-cell simulations describing cyclotron radio emission from Earth's auroral region and similar phenomena in other astrophysical environments. In particular, we find that the ...
  • Balanced solutions for an ellipsoidal vortex in a rotating stratified flow 

    Mckiver, William J.; Dritschel, David G. (2016-09) - Journal article

  • A Bayesian approach to fitting Gibbs processes with temporal random effects 

    King, Ruth; Illian, Janine Baerbel; King, Stuart Edward; Nightingale, Glenna Faith; Hendrichsen, Ditte (2012-12) - Journal article

    Swallow, Benjamin Thomas; Buckland, Stephen Terrence; King, Ruth; Toms, Mike (2016-03) - Journal article
    The development of methods for dealing with continuous data with a spike at zero has lagged behind those for overdispersed or zero-inflated count data. We consider longitudinal ecological data corresponding to an annual ...
