    Fry, Cynthia Ann (University of St Andrews, 2014-10-23) - Thesis
    This thesis is the first attempt to provide an assessment of Scottish-Jacobean foreign relations within a European context in the years before 1603. Moreover, it represents the only cohesive study of the events that formed ...
  • Dirac surface states and nature of superconductivity in noncentrosymmetric BiPd 

    Sun, Zhixiang; Enayat, Mostafa; Maldonado Cid, Ana Isabel; Lithgow, Calum; Yelland, Ed; Peets, Darren C.; Yaresko, Alexander; Schnyder, Andreas P.; Wahl, Peter (2015-03-30) - Journal article
    In non-magnetic bulk materials, inversion symmetry protects the spin degeneracy. If the bulk crystal structure lacks a center of inversion, however, spin-orbit interactions lift the spin-degeneracy, leading to a Rashba ...
  • Direct comparison of Xpert MTB/RIF assay with liquid and solid mycobacterial culture for quantification of early bactericidal activity 

    Kayigire, Xavier A.; Friedrich, Sven O.; Venter, Amour; Dawson, Rodney; Gillespie, Stephen Henry; Boeree, Martin J.; Heinrich, Norbert; Hoelscher, Michael; Diacon, Andreas H. (2013-04) - Journal article
    The early bactericidal activity of antituberculosis agents is usually determined by measuring the reduction of the sputum mycobacterial load over time on solid agar medium or in liquid culture. This study investigated the ...
  • Direct evidence that density-dependent regulation underpins the temporal stability of abundant species in a diverse animal community 

    Henderson, P.A.; Magurran, A.E. (2014-09-22) - Journal article
    To understand how ecosystems are structured and stabilized, and to identify when communities are at risk of damage or collapse, we need to know how the abundances of the taxa in the entire assemblage vary over ecologically ...
  • Direct fiber-coupled single photon source based on a photonic crystal waveguide 

    Ahn, B.-H.; Lee, C.-M.; Lim, H.-J.; Schlereth, T.W.; Kamp, M.; Höfling, Sven; Lee, Y.-H. (2015-08-24) - Journal article
    A single photon source plays a key role in quantum applications such as quantum computers and quantum communications. Epitaxially grown quantum dots are one of the promising platforms to implement a good single photon ...
  • A direct interaction between mitochondrial proteins and amyloid-β peptide and its significance for the development and treatment of Alzheimer’s disease 

    Benek, Ondrej; Aitken, Laura; Hroch, Lukas; Kuca, Kamil; Gunn-Moore, Frank J; Musilek, Kamil (2015) - Journal article
    The amyloid-β peptide (Aβ) has been associated with Alzheimer’s disease (AD) for decades. The original amyloid cascade hypothesis declared that the insoluble extracellular plaques were responsible for Aβ toxicity. Later, ...
  • Direct moral grounding and the legal model of moral normativity 

    Sachs, Benjamin Alan (2015-04) - Journal article
    Whereas most moral philosophers believe that the facts as to what we’re morally required to do are grounded by the facts about our moral reasons, which in turn are grounded by non-normative facts, I propose that moral ...
  • Direct observation of intersystem crossing in a thermally activated delayed fluorescence copper complex in the solid state 

    Bergmann, Larissa; Hedley, Gordon James; Baumann, Thomas; Braese, Stefan; Samuel, Ifor David William (2016-01-01) - Journal article
    Intersystem crossing in thermally activated delayed fluorescent (TADF) materials is an important process that controls the rate at which singlet states convert to triplets, measuring this directly in TADF materials is ...
  • Direct observation of spin-polarized bulk bands in an inversion-symmetric semiconductor 

    Riley, Jonathon Mark; Mazzola, F.; Dendzik, M.; Michiardi, M.; Takayama, T.; Bawden, Lewis; Granerød, C.; Leandersson, M.; Balasubramanian, T.; Hoesch, M.; Kim, T. K.; Takagi, H.; Meevasana, W.; Hofmann, Ph.; Bahramy, M. S.; Wells, J. W.; King, Phil (2014-11) - Journal article
    Methods to generate spin-polarized electronic states in non-magnetic solids are strongly desired to enable all-electrical manipulation of electron spins for new quantum devices1. This is generally accepted to require ...
  • Direct synthesis of fused 1,2,5-selenadiazoles from 1,2,5-thiadiazoles 

    Konstantinova, Lidia S.; Knyazeva, Ekaterina A.; Nefyodov, Andrey A.; Sanz Camacho, Paula; Ashbrook, Sharon Elizabeth Marie; Woollins, J Derek; Zibarev, Andrey V.; Rakitin, Oleg A. (2015-02) - Journal article
    A short and convenient synthesis of fused 1,2,5-selenadiazoles from corresponding 1,2,5-thiadiazoles and selenium dioxide has been developed.
  • Directed graph iterated function systems 

    Boore, Graeme C. (University of St Andrews, 2011-11-30) - Thesis
    This thesis concerns an active research area within fractal geometry. In the first part, in Chapters 2 and 3, for directed graph iterated function systems (IFSs) defined on ℝ, we prove that a class of 2-vertex directed ...
  • Directional organic light-emitting diodes using photonic microstructure 

    Zhang, Shuyu (University of St Andrews, 2014-05-19) - Thesis
    This thesis describes investigations into the optical and device design of organic light-emitting diodes (OLEDs) with the aim of exploring the factors controlling the spatial emission pattern of OLEDs and developing novel ...
  • Directly observing continuum emission from self-gravitating spiral waves 

    Hall, Cassandra; Forgan, Duncan; Rice, Ken; Harries, Tim J.; Klaassen, Pamela D.; Biller, Beth (2016-05-01) - Journal article
    We use a simple, self-consistent, self-gravitating semi-analytic disc model to conduct an examination of the parameter space in which self-gravitating discs may exist. We then use Monte Carlo radiative transfer to generate ...
  • Disagreements, philosophical and otherwise

    Simón-Porcar, Violeta I.; Meagher, Thomas Robert; Arroyo, Juan (2015) - Journal article
    Evolution to reduce inbreeding can favor disassortative (inter-morph) over assortative (intramorph) mating in hermaphroditic sexually polymorphic plant species. Heterostyly enhances disassortative pollination through ...
