  • The coevolution of building nests on the ground and domed nests in Timaliidae 

    Hall, Z.J.; Street, S.E.; Auty, S.; Healy, S.D. (2015-07) - Journal article
    Despite the accumulation of structural descriptions of bird nests and considerable diversity in these structures across species, we know little about why birds build the nests that they do. Here we used phylogenetic ...
  • The coevolution of virulence : tolerance in perspective 

    Little, Tom J.; Shuker, David M.; Colegrave, Nick; Day, Troy; Graham, Andrea L. (2010-09) - Journal item
    Coevolutionary interactions, such as those between host and parasite, predator and prey, or plant and pollinator, evolve subject to the genes of both interactors. It is clear, for example, that the evolution of pollination ...
  • Cognition in inter-group relations : the effect of group membership on theory of mind and its precursors 

    McClung, Jennifer (University of St Andrews, 2012) - Thesis
    Social categorization based on group membership has a significant and broad influence on behaviour (Turner, Hogg, Oakes, Reicher, & Wetherell, 1987). People perceived as being of the same group, ‘in-group’ members, are ...
  • Cognitive and brain function in adults with Type 1 diabetes mellitus : is there evidence of accelerated ageing? 

    Johnston, Harriet N. (University of St Andrews, 2013-06-25) - Thesis
    The physical complications of Type 1 diabetes mellitus (T1DM) have been understood as an accelerated ageing process (Morley, 2008). Do people with T1DM also experience accelerated cognitive and brain ageing? Using findings ...
  • A cognitive approach to the study of culture in wild chimpanzees (Pan troglodytes schweinfurthii) 

    Gruber, Thibaud (University of St Andrews, 2011-11-30) - Thesis
    The question of animal culture has been of interest for decades. Chimpanzees (Pan troglodytes) have played a key role in the debate of whether or not it is appropriate to use the term ‘culture’ to describe animal behaviour ...
  • Cognitive aspects of travel and food location by chimpanzees (Pan troglodytes schweinfurthii) of the Budongo Forest Reserve, Uganda 

    Bates, Lucy (University of St Andrews, 2005) - Thesis
    Finding food in tropical forests poses a potentially major problem for chimpanzees, whose ranging is thought primarily to be directed at locating suitable food resources: (1) chimpanzees are frugivorous, large bodied and ...
  • Cognitive processes associated with sequential tool use in New Caledonian crows 

    Wimpenny, Joanna H.; Weir, Alex A. S.; Clayton, Lisa; Rutz, Christian; Kacelnik, Alex (2009-08-05) - Journal article
    Background: Using tools to act on non-food objects-for example, to make other tools-is considered to be a hallmark of human intelligence, and may have been a crucial step in our evolution. One form of this behaviour, ...
  • A cognitive prosthesis and communication support for people with dementia 

    Alm, N; Astell, Arlene Jean; Ellis, Maggie; Dye, R; Gowans, G; Campbell, J (2004-03) - Journal article
    Computers may have the potential to augment human cognitive processes in ways that could be beneficial for people with dementia. This possibility is being investigated by a multidisciplinary team. Previous work on improving ...
  • Coherence dynamics and quantum-to-classical crossover in an exciton-cavity system in the quantum strong coupling regime 

    Kasprzak, J.; Sivalertporn, K.; Albert, F.; Schneider, C.; Höfling, Sven; Kamp, M.; Forchel, A.; Reitzenstein, S.; Muljarov, E. A.; Langbein, W. (2013-04-22) - Journal article
    Interaction between light and matter generates optical nonlinearities, which are particularly pronounced in the quantum strong coupling regime. When a single bosonic mode couples to a single fermionic mode, a Jaynes-Cummings ...
  • Coherent and passive one dimensional quantum memory 

    Ping, Y.; Jefferson, J.H.; Lovett, B.W. (2014-10-16) - Journal article
    We show that the state of a flying qubit may be transferred to a chain of identical, (near) ferromagnetically polarized, but non-interacting, static spin-1/2 particles in a passive way. During this process the flying qubit ...
  • Coherent control of plasmonic nanoantennas using optical eigenmodes 

    Kosmeier, Sebastian; De Luca, Anna Chiara; Zolotovskaya, Svetlana; Di Falco, Andrea; Dholakia, Kishan; Mazilu, Michael (2013-05-09) - Journal article
    The last decade has seen subwavelength focusing of the electromagnetic field in the proximity of nanoplasmonic structures with various designs. However, a shared issue is the spatial confinement of the field, which is ...
  • Coherent exciton dynamics in a dissipative environment maintained by an off-resonant vibrational mode 

    Levi, Elliott Kendrick; Irish, E. K.; Lovett, Brendon William (2016-04) - Journal article
    The interplay between an open quantum system and its environment can lead to both coherent and incoherent behavior. We explore the extent to which strong coupling to a single bosonic mode can alter the coherence properties ...
  • Coherent mode coupling in highly efficient top-emitting OLEDs on periodically corrugated substrates 

    Schwab, Tobias; Fuchs, Cornelius; Scholz, Reinhard; Zakhidov, Alexander; Leo, Karl; Gather, Malte Christian (2014-03-25) - Journal article
    Bragg scattering at one-dimensional corrugated substrates allows to improve the light outcoupling from top-emitting organic light-emitting diodes (OLEDs). The OLEDs rely on a highly efficient phosphorescent pin stack and ...
  • Coherent polariton laser 

    Kim, Seonghoon; Zhang, Bo; Wang, Zhaorong; Fischer, Julian; Brodbeck, Sebastian; Kamp, Martin; Schneider, Christian; Höfling, Sven; Deng, Hui (2016-03-11) - Journal article
    The semiconductor polariton laser promises a new source of coherent light, which, compared to conventional semiconductor photon lasers, has input-energy threshold orders of magnitude lower. However, intensity stability, a ...
  • Coherent quasiparticles with a small fermi surface in lightly doped Sr3Ir2O7 

    De La Torre, Alberto; Hunter, E. C.; Subedi, A.; McKeown Walker, Siobhan Ellen; Tamai, Anna; Kim, T. K.; Hoesch, M.; Perry, Robin Stuart; Georges, A.; Baumberger, F. (2014-12-16) - Journal article
    We characterize the electron doping evolution of (Sr1-xLax)3Ir2O7 by means of angle-resolved photoemission. Concomitant with the metal insulator transition around x ≈ 0.05 we find the emergence of coherent quasiparticle ...
  • Coherent State Transfer between an Electron and Nuclear Spin in N-15@C-60 

    Brown, Richard M.; Tyryshkin, Alexei M.; Porfyrakis, Kyriakos; Gauger, Erik M.; Lovett, Brendon W.; Ardavan, Arzhang; Lyon, S. A.; Briggs, G. Andrew D.; Morton, John J. L. (2011-03-14) - Journal article
    Electron spin qubits in molecular systems offer high reproducibility and the ability to self-assemble into larger architectures. However, interactions between neighboring qubits are "always on," and although the electron ...
  • Cohort differences in the levels and trajectories of frailty among older people in England 

    Marshall, Alan David; Nazroo, James; Tampubolon, Gindo; Vanhoutte, Bram (2015-04) - Journal article
    Background The level of frailty in the older population across age cohorts and how this changes is a factor in determining future care costs and may also influence the extent of socioeconomic and gender inequalities in ...
  • Coincidence and modality 

    Kang, Li (University of St Andrews, 2011) - Thesis
    How should we understand de re modal features of objects, if there are such features? Any answer to the question is connected to how we should think about coincident objects, objects which occupy the same spatio-temporal ...
  • Cold dust in hot regions 

    Sreenilayam, G.; Fich, M.; Ade, P.; Bintley, D.; Chapin, E.; Chrysostomou, A.; Dunlop, J.S.; Gibb, A.; Greaves, J.S.; Halpern, M.; Holland, W.S.; Ivison, R.; Jenness, T.; Robson, I.; Scott, D. (2014-03-01) - Journal article
    We mapped five massive star-forming regions with the SCUBA-2 camera on the James Clerk Maxwell Telescope. Temperature and column density maps are obtained from the SCUBA-2 450 and 850 μm images. Most of the dense clumps ...
  • Cold war theology: a controversial religious image of King James VI & I in England and on the Continent in 1603 

    Hazlett, Ian (St Mary's College, University of St Andrews, 2012-06-01) - Journal article
    A former student of James Cameron’s, Ian Hazlett contributes a paper very much in the spirit of his teacher. It considers the afterlife of the King’s (or Negative) Confession, commissioned by James VI of Scotland in 1581 ...
