    McLeod, Naomi (University of St Andrews, 2012-06-21) - Thesis
    Equatorial Guinea is the only former Spanish colony in Africa south of the Sahara. Consequently, the Spanish-language literature produced by its authors has been resistant to classification in both the fields of Hispanic ...
  • Extended baseline photometry of rapidly changing weather patterns on the brown dwarf binary Luhman-16 

    Street, Rachel Amanda; Fulton, B.J.; Scholz, Alexander; Horne, Keith Douglas; Helling, Christiane; Juncher, Diana; Lee, Graham Kim Huat; Valenti, S. (2015-10-20) - Journal article
    Luhman-16 (WISE J1049-5319) was recently discovered to be a nearby (∼2 pc) brown dwarf binary that exhibits a high degree of photometric variability (Δm ∼ 0.1 mag). This is thought to be due to the evolution of "cloud" ...
  • Extended contact effects as a function of closeness of relationship with ingroup contacts 

    Tausch, Nicole; Hewstone, Miles; Schmid, Katharina; Hughes, Joanne; Cairns, Ed (2011-03) - Journal article
    Using survey data from Catholics and Protestants in Northern Ireland (N = 428), the authors examined the effects of extended contact via different types of ingroup contacts (neighbors, work colleagues, friends, and family ...

    Martin, Anthony; Chartoire, Anthony Raymond Georges; Slawin, Alexandra Martha Zoya; Nolan, Steven Patrick (2012-09-27) - Journal article
    The use of [Pd(NHC)(cinnamyl)Cl] precatalysts in the direct arylation of heterocycles has been investigated. Among four different precatalysts, [Pd(SIPr)(cinnamyl)Cl] proved to be the most efficient promoter of the reaction. ...
  • Extensible automated constraint modelling via refinement of abstract problem specifications 

    Akgün, Özgür (University of St Andrews, 2014-06-25) - Thesis
    Constraint Programming (CP) is a powerful technique for solving large-scale combinatorial (optimisation) problems. Constraint solving a given problem proceeds in two phases: modelling and solving. Effective modelling has ...
  • An extension of geographically weighted regression with flexible bandwidths 

    Yang, Wenbai (University of St Andrews, 2014) - Thesis
    Various statistical methods have been developed for local spatial analysis. Among them Geographically Weighted Regression (GWR) is a simple yet powerful method to explore spatially varying relationships between variables. ...
  • Extensive DNA mimicry by the ArdA anti-restriction protein and its role in the spread of antibiotic resistance 

    McMahon, Stephen A.; Roberts, Gareth A.; Johnson, Kenneth A.; Cooper, Laurie P.; Liu, Huanting; White, John H.; Carter, Lester G.; Sanghvi, Bansi; Oke, Muse; Walkinshaw, Malcolm D.; Blakely, Garry W.; Naismith, James Henderson; Dryden, David T. F. (2009-08) - Journal article
    The ardA gene, found in many prokaryotes including important pathogenic species, allows associated mobile genetic elements to evade the ubiquitous Type I DNA restriction systems and thereby assist the spread of resistance ...
  • Extensive lysine methylation in hyperthermophilic crenarchaea : potential implications for protein stability and recombinant enzymes 

    Botting, Catherine H.; Talbot, Paul; Paytubi, Sonia; White, Malcolm F. (2010) - Journal article
    In eukarya and bacteria, lysine methylation is relatively rare and is catalysed by sequence-specific lysine methyltransferases that typically have only a single-protein target. Using RNA polymerase purified from the ...
  • The extent and costs of reproductive interference among four species of true bug 

    Shuker, David M.; Currie, Niall; Hoole, Tara; Burdfield-Steel, Emily R. (2015-04) - Journal article
    Reproductive interference arises when individuals of one species engage in reproductive activities with individuals of another, leading to fitness costs in one or both species. Reproductive interference (RI) therefore has ...
  • External cavity diode lasers and non-linear optical frequency conversion in spectroscopic applications 

    Shah, Anjali (University of St Andrews, 2006-05) - Thesis
    Semiconductor diode lasers are successful tools in atomic spectroscopy. They are routinely used in frequency conversion applications to develop devices that access regions of the spectrum not directly available. This thesis ...
  • An externally validated age-related model of mean follicle density in the cortex of the human ovary 

    McLaughlin, Marie; Kelsey, Tom; Wallace, W Hamish B; Anderson, Richard A; Telfer, Evelyn E (2015-06) - Journal article
    The population of non-growing follicles present in the ovary is defined as the ovarian reserve. This underpins the reproductive lifespan in women, with its depletion determining age at loss of fertility and the menopause. ...
  • Extortion and the ethics of "topping up" 

    Sachs, Benjamin (2009-10) - Journal item
  • Extracting insights from the shape of complex data using topology 

    Lum, P. Y.; Singh, G.; Lehman, A.; Ishkanov, T.; Alagappan, M.; Carlsson, J.; Carlsson, G.; Vejdemo Johansson, Mikael Vilhelm (2013-02-07) - Journal article
    This paper applies topological methods to study complex high dimensional data sets by extracting shapes (patterns) and obtaining insights about them. Our method combines the best features of existing standard methodologies ...
  • Extraction of group index of lossy photonic crystal waveguides 

    Debnath, Amrita; Debnath, Kapil; O'Faolain, Liam (2015-01-15) - Journal article
    We present a numerical approach to extract group index in photonic crystal (PhC) waveguides using two- and three-dimensional finite-difference time-domain methods and make a quantitative study of the effects of loss on ...
  • Extragalactic and cosmological tests of gravity theories with additional scalar or vector fields 

    Feix, Martin (University of St Andrews, 2011-06-24) - Thesis
    Despite the many successes of the current standard model of cosmology on the largest physical scales, it relies on two phenomenologically motivated constituents, cold dark matter and dark energy, which account for approximately ...
