  • The evolutionary ecology of the Lygaeidae 

    Burdfield-Steel, Emily R.; Shuker, David M. (2014-06) - Journal item
    The Lygaeidae (sensu lato) are a highly successful family of true bugs found worldwide, yet many aspects of their ecology and evolution remain obscure or unknown. While a few species have attracted considerable attention ...
  • Evolutionary genetics and genomics of the female side of sexual interactions in Drosophila 

    Immonen, Elina (University of St Andrews, 2012-11-30) - Thesis
    Sexual interactions play an important role in generating sexual selection and antagonistic co-evolution. These forces can shape differences between the sexes, but also have the potential to generate population divergence ...
  • Evolutionary origins of human handedness : evaluating contrasting hypotheses 

    Cochet, Hélène; Byrne, Richard William (2013-07) - Journal article
    Variation in methods and measures, resulting in past dispute over the existence of population handedness in nonhuman great apes, has impeded progress into the origins of human right-handedness and how it relates to the ...
  • The evolutionary roots of creativity : mechanisms and motivations 

    Wiggins, Geraint A.; Tyack, Peter Lloyd; Scharff, Constance; Rohrmeier, Martin (2015-03) - Journal article
    We consider the evolution of cognition and the emergence of creative behaviour, in relation to vocal communication. We address two key questions: (i) what cognitive and/or social mechanisms have evolved that afford aspects ...
  • Evolutionary trade-offs underlie the multi-faceted virulence of Staphylococcus aureus 

    Laabei, Maisem; Uhlemann, Anne-Catrin; Lowy, Franklin D; Austin, Eloise D; Yokoyama, Maho; Ouadi, Khadija; Feil, Edward; Thorpe, Harry A; Williams, Barnabas; Perkins, Mark; Peacock, Sharon J; Clarke, Stephen R; Dordel, Janina; Holden, Matthew; Votintseva, Antonina A; Bowden, Rory; Crook, Derrick W; Young, Bernadette C; Wilson, Daniel J; Recker, Mario; Massey, Ruth C (2015-09-02) - Journal article
    Bacterial virulence is a multifaceted trait where the interactions between pathogen and host factors affect the severity and outcome of the infection. Toxin secretion is central to the biology of many bacterial pathogens ...
  • Evolving complex systems from simple molecules 

    Sadownik, Jan (University of St Andrews, 2009) - Thesis
    Until very recently, synthetic chemistry has focussed on the creation of chemical entities with desirable properties through the programmed application of isolated chemical reactions, either individually or in a cascade ...
  • Evolving database systems : a persistent view 

    Kirby, G. N. C.; Morrison, R.; Connor, R. C. H.; Zdonik, S. B. (University of St Andrews, 1997) - Report
    Orthogonal persistence ensures that information will exist for as long as it is useful, for which it must have the ability to evolve with the growing needs of the application systems that use it. This may involve evolution ...
  • An exact collisionless equilibrium for the Force-Free Harris Sheet with low plasma beta 

    Allanson, Oliver Douglas; Neukirch, Thomas; Wilson, Fiona; Troscheit, Sascha (2015-10) - Journal article
    We present a first discussion and analysis of the physical properties of a new exact collisionless equilibrium for a one-dimensional nonlinear force-free magnetic field, namely, the force-free Harris sheet. The solution ...
  • Exact dimensionality and projections of random self-similar measures and sets 

    Falconer, Kenneth; Jin, Xiong (2014-09) - Journal article
    We study the geometric properties of random multiplicative cascade measures defined on self-similar sets. We show that such measures and their projections and sections are almost surely exact-dimensional, generalizing Feng ...
  • Examination of text-entry methods for tabletop displays 

    Hinrichs, Uta; Hancock, Mark S.; Collins, Christopher; Carpendale, Sheelagh (IEEE, 2007-10-10) - Conference item
    Although text entry is a vital part of day-to-day computing familiar to most people, not much research has been done to enable text entry on large interactive tables. One might assume that a good approach would be to choose ...
  • Examining fish quality : the evaluation of the use of lipids as a measure of condition in wild Atlantic salmon 

    Howe, Alexandra Jane (University of St Andrews, 2015-06-24) - Thesis
    Considering the response of organisms to their environment is difficult; it is made more so if population numbers cannot be closely monitored. In such cases different methods of population assessment are required. This ...
  • Examining monetary policy transmission in the People's Republic of China – structural change models with a Monetary Policy Index 

    Egan, Paul Gerard; Leddin, Anthony J. (2016-03) - Journal article
    This paper estimates augmented versions of the Investment–Saving curve for the People's Republic of China in an attempt to examine the relationship between monetary policy and the real economy. It endeavors to account for ...
  • Examining the response of top marine predators to ecological change using stable isotope proxies 

    Hanson, Nora Nell (University of St Andrews, 2012-11-30) - Thesis
