  • Community-level regulation of temporal trends in biodiversity 

    Gotelli, Nicholas; Shimadzu, Hideyasu; Dornelas, Maria; McGill, Brian; Moyes, Faye; Magurran, Anne E. (2017-07-26) - Journal article
    Many theoretical models of community dynamics predict that species richness (S) and total abundance (N) are regulated in their temporal fluctuations. Here we present novel evidence for widespread regulation of biodiversity. ...
  • Community-specific evaluation of tool affordances in wild chimpanzees 

    Gruber, Thibaud; Muller, Martin N.; Reynolds, Vernon; Wrangham, Richard; Zuberbuehler, Klaus (2011-11-03) - Journal article
    The notion of animal culture, defined as socially transmitted community-specific behaviour patterns, remains controversial, notably because the definition relies on surface behaviours without addressing underlying cognitive ...
  • A commutative noncommutative fractal geometry 

    Samuel, Anthony (University of St Andrews, 2010) - Thesis
    In this thesis examples of spectral triples, which represent fractal sets, are examined and new insights into their noncommutative geometries are obtained. Firstly, starting with Connes' spectral triple for a non-empty ...

    McKay, Johannes Erik; Robertson, Duncan Alexander; Speirs, Peter James; Hunter, Robert Iain; Wylde, Richard John; Smith, Graham Murray (2016-06) - Journal article
    We demonstrate that very high performance, extremely compact, scalar corrugated feedhorns can be designed and constructed by optimizing the excitation and phasing of the HE11, HE12 and HE13 modes near the throat of the ...
  • A compact light-sheet microscope for the study of the mammalian central nervous system 

    Yang, Zhengyi; Haslehurst, Peter; Scott, Suzanne; Emptage, Nigel; Dholakia, Kishan (2016-05-24) - Journal article
    Investigation of the transient processes integral to neuronal function demands rapid and high-resolution imaging techniques over a large field of view, which cannot be achieved with conventional scanning microscopes. Here ...
  • Compact objects in active galactic nuclei and X-ray binaries 

    Cackett, Edward M. (University of St Andrews, 2007) - Thesis
    In this thesis I study the inner-most regions of Active Galactic Nuclei (AGN) using the reverberation mapping technique, and neutron star low-mass X-ray binaries in quiescence using X-ray observations. Using the 13-year ...
  • A compact system for ultracold atoms 

    Torralbo Campo, Lara (University of St Andrews, 2012-11-30) - Thesis
    This thesis describes the design, construction and optimisation of two compact setups to produce ⁸⁷Rb Bose-Einstein condensates and dual ⁷Li-⁸⁷Rb Magneto-Optical Traps (MOTs). The motivation for compact systems is to have ...
  • Company Law Review response 

    Sustainable Development Commission (Sustainable Development Commission, 2001-10-01) - Report
    A letter to the Department for Trade and Industry in reference to the Company Law Review.
  • Comparative analysis of decision-making processes with respect to U.S. armaments procurement: a case study of the F-16 

    Parks, Mark E. (University of St Andrews, 1988) - Thesis
    The overall purpose of this thesis is to question the value of the use of models regarding decision-making as it effectively operates within the environment of US armaments procurements. For example, conceptual framework ...
  • A comparative analysis of whole genome sequencing of esophageal adenocarcinoma pre- and post-chemotherapy 

    Noorani, Ayesha; Bornschein, Jan; Lynch, Andy G; Secrier, Maria; Achilleos, Achilleas; Eldridge, Matthew; Bower, Lawrence; Weaver, Jamie M.J.; Crawte, Jason; Ong, Chin-Ann; Shannon, Nicholas; MacRae, Shona; Grehan, Nicola; Nutzinger, Barbara; O'Donovan, Maria; Hardwick, Richard; Tavaré, Simon; Fitzgerald, Rebecca C.; on behalf of the Oesophageal Cancer Clinical and Molecular Stratification (OCCAMS) Consortium (2017-06-01) - Journal article
    The scientific community has avoided using tissue samples from patients that have been exposed to systemic chemotherapy to infer the genomic landscape of a given cancer. Esophageal adenocarcinoma is a heterogeneous, ...
  • A comparative and evolutionary analysis of the cultural cognition of humans and other apes 

    Whiten, Andrew (2017-01-09) - Journal article
    The comparative and evolutionary analysis of social learning and all manner of cultural processes has become a flourishing field. Applying the ‘comparative method’ to such phenomena allows us to exploit the good fortunate ...
  • A comparative assessment of constitutionalism in Western and Islamic thought 

    Kleidosty, Jeremy Scott (University of St Andrews, 2013) - Thesis
    In the spirit of comparative political theory, this thesis analyzes the ideas that have shaped Western and Islamic constitutional discourse and assesses the extent to which they intersect at key historical and philosophical ...
  • Comparative estuarine dynamics : trophic linkages and ecosystem function 

    Kenworthy, Joseph (University of St Andrews, 2016-02-01) - Thesis
    Estuarine systems are of crucial importance to the provision of goods and services on a global scale. High human population densities in coastal systems have caused an increasing input of pollutants, of which nutrient ...
  • Comparative genomics of vancomycin-resistant Staphylococcus aureus strains and their positions within the clade most commonly associated with methicillin-resistant S. aureus hospital-acquired infection in the United States 

    Kos, Veronica N.; Desjardins, Christopher A.; Griggs, Allison; Cerqueira, Gustavo; Van Tonder, Andries; Holden, Matthew T.
