      Efficient (similar to 1%) electron cyclotron radio emissions are known to originate in the X mode from regions of locally depleted plasma in the Earths polar magnetosphere. These emissions are commonly referred to as the ...
    • 3D pic simulations of collisionless shocks at lunar magnetic anomalies and their role in forming lunar swirls

      Investigation of the lunar crustal magnetic anomalies offers a comprehensive long-term data set of observations of small-scale magnetic fields and their interaction with the solar wind. In this paper a review of the ...
    • 3D whole-prominence fine structure modeling. II. Prominence evolution 

      Gunar, Stanislav; Mackay, Duncan Hendry (2015-10-20) - Journal article
      We use the new three-dimensional (3D) whole-prominence fine structure model to study the evolution of prominences and their fine structures in response to changes in the underlying photospheric magnetic flux distribution. ...
    • 5-hydroxymethylcytosine marks promoters in colon that resist DNA hypermethylation in cancer 

      Uribe-Lewis, Santiago; Stark, Rory; Carroll, Thomas; Dunning, Mark J.; Bachman, Martin; Ito, Yoko; Stojic, Lovorka; Halim, Silvia; Vowler, Sarah L.; Lynch, Andy G.; Delatte, Benjamin; de Bony, Eric J.; Colin, Laurence; Defrance, Matthieu; Krueger, Felix; Silva, Ana Luisa; ten Hoopen, Rogier; Ibrahim, Ashraf E.K.; Fuks, François; Murrell, Adele (2015-04-01) - Journal article
      Background : The discovery of cytosine hydroxymethylation (5hmC) as a mechanism that potentially controls DNA methylation changes typical of neoplasia prompted us to investigate its behaviour in colon cancer. 5hmC is ...
    • 50-Year Anniversary of Papers by Cormack, Jolly and Seber 

      Buckland, Stephen Terrence; Morgan, Byron J T (2016-05) - Journal item
    • Above the noise : the search for periodicities in the inner heliosphere 

      Threlfall, James William; De Moortel, Ineke; Conlon, Thomas Michael (2017-11) - Journal article
      Remote sensing of coronal and heliospheric periodicities can provide vital insight into the local conditions and dynamics of the solar atmosphere. We seek to trace long (one hour or longer) periodic oscillatory signatures ...
    • Accounting for preferential sampling in species distribution models 

      Pennino, Maria Grazia; Paradinas, Iosu; Illian, Janine B.; Muñoz, Facundo; Bellido, José María; López-Quílez, Antonio; Conesa, David (2019-01-01) - Journal article
      Species distribution models (SDMs) are now being widely used in ecology for management and conservation purposes across terrestrial, freshwater, and marine realms. The increasing interest in SDMs has drawn the attention ...
    • Adaptive distance sampling 

      Pollard, John (University of St Andrews, 2002) - Thesis
      We investigate mechanisms to improve efficiency for line and point transect surveys of clustered populations by combining the distance methods with adaptive sampling. In adaptive sampling, survey effort is increased when ...
    • Adaptive multivariate global testing 

      Minas, Giorgos; Aston, John A D; Stallard, Nigel (2014-06) - Journal article
      We present a methodology for dealing with recent challenges in testing global hypotheses using multivariate observations. The proposed tests target situations, often arising in emerging applications of neuroimaging, where ...
    • 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 ...
    • Affine rigidity and conics at infinity 

      Connelly, Robert; Gortler, Steven J.; Theran, Louis (2018-07) - Journal article
      We prove that if a framework of a graph is neighborhood affine rigid in d-dimensions (or has the stronger property of having an equilibrium stress matrix of rank n — d — 1) then it has an affine flex (an affine, but non ...
    • Alfven wave phase-mixing and damping in the ion cyclotron range of frequencies 

      Threlfall, J.; McClements, K. G.; De Moortel, I. (2011-01) - Journal article
      Aims. We determine the effect of the Hall term in the generalised Ohm's law on the damping and phase mixing of Alfven waves in the ion cyclotron range of frequencies in uniform and non-uniform equilibrium plasmas. Methods. ...
    • Alfvén wave boundary condition for responsive magnetosphere- ionosphere coupling 

      Wright, A.N.; Russell, A.J.B. (2014-05-01) - Journal article
      The solution of electric fields and currents in a height-resolved ionosphere is traditionally solved as an elliptic equation with Dirichlet or Neumann boundary condition in which the magnetosphere is represented as an ...
    • Alfvén waves in low-mass star-forming regions 

      Martin, Clare E. (University of St Andrews, 1999) - Thesis
      Low-mass star-forming regions have a lifetime which is greater than their dynamical time and must therefore be, in an average sense, in mechanical equilibrium. The work presented here proposes that an equilibrium exists ...
    • An algebraic formulation of asmptotically separable quantum mechanics 

      McLean, R. G. Derek (University of St Andrews, 1984) - Thesis
      This thesis explores the possibility of an algebraic formulation of non-relativistic quantum theory in which certain paradoxes associated with non-locality may be resolved. It is shown that the localisation of a free quantum ...

      Heggie, Patricia, M. (University of St Andrews, 1991) - Thesis
      One of the main algorithms of computational group theory is the Todd-Coxeter coset enumeration algorithm, which provides a systematic method for finding the index of a subgroup of a finitely presented group. This has been ...

      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 ...
