  • Obesity and smoking : can we catch two birds with one tax? 

    Dragone, Davide; Manaresi, Francesco; Savorelli, Luca (University of St Andrews, 2013-07) - Working or discussion paper
    The debate on tobacco and fat taxes often treats smoking and eating as independent behaviors. However, the available evidence shows that they are interdependent, which implies that policies against smoking or obesity may ...
  • Obesity and the ageing brain : could leptin play a role in neurodegeneration? 

    Doherty, Gayle Helane (2011) - Journal article
    Obesity and ageing are both characteristics of the human population that are on the increase across the globe. It has long been established that ageing is the major risk factor for neurodegenerative conditions such as ...

    Issa, Christine (University of St Andrews, 1988) - Thesis
    The thesis seeks to explore alleged differences in kinship and family relations within County Durham, an area of wide geographical, social and economic diversity. A study of recognition that reveals that kinship ties ...
  • Obligations of love : international political thought & the tradition of natural law 

    Beattie, Amanda Russell (University of St Andrews, 2008-06-25) - Thesis
    Identifying human suffering as a socio-political phenomenon challenging the well-being and development of individuals, this work argues that International Relations requires a re-evaluation of its political structures in ...
  • Observables, maximal symmetric operators, POV measures and their applications in quantum mechanics 

    Fountain, Robert H. (University of St Andrews, 1996) - Thesis
    Approximate observables, their description in terms of POV measures and the subsequent extension of the orthodox notion of observable are examined. The sense in which the approximate observables are non-ideal observables is ...
  • Observation of a cascaded process in intracavity terahertz optical parametric oscillators based on lithium niobate 

    Thomson, C. L.; Dunn, M. H. (2013-07-29) - Journal article
    Cascaded difference frequency generation has been observed in intracavity optical parametric oscillators based on bulk lithium niobate and producing nanosecond pulses of terahertz radiation. Two idler waves are generated, ...
  • Observation of Dirac surface states in the noncentrosymmetric superconductor BiPd 

    Benia, H. M.; Rampi, E.; Trainer, C.; Yim, C. M.; Maldonado, A.; Peets, D. C.; Stoehr, A.; Starke, U.; Kern, K.; Yaresko, A.; Levy, G.; Damascelli, A.; Ast, C. R.; Schnyder, A. P.; Wahl, P. (2016) - Journal article
    Materials with strong spin-orbit coupling (SOC) have in recent years become a subject of intense research due to their potential applications in spintronics and quantum information technology. In particular, in systems ...
  • Observation of non-Hermitian degeneracies in a chaotic exciton-polariton billiard 

    Gao, T.; Estrecho, E.; Bliokh, K.Y.; Liew, T.C.H.; Fraser, M.D.; Brodbeck, S.; Kamp, M.; Schneider, C.; Höfling, Sven; Yamamoto, Y.; Nori, F.; Kivshar, Y.S.; Truscott, A.G.; Dall, R.G.; Ostrovskaya, E.A. (2015-10-22) - Journal item
    Exciton-polaritons are hybrid light-matter quasiparticles formed by strongly interacting photons and excitons (electron-hole pairs) in semiconductor microcavities. They have emerged as a robust solid-state platform for ...
  • Observation of resonance fluorescence and the Mollow triplet from a coherently driven site-controlled quantum dot 

    Unsleber, Sebastian; Maier, Sebastian; McCutcheon, Dara P. S.; He, Yu-Ming; Dambach, Michael; Gschrey, Manuel; Gregersen, Niels; Mørk, Jesper; Reitzenstein, Stephan; Höfling, Sven; Schneider, Christian; Kamp, Martin (2015-12-16) - Journal article
    Resonant excitation of solid state quantum emitters has the potential to deterministically excite a localized exciton while ensuring maximally coherent emission. In this work, we demonstrate the coherent coupling of an ...
  • Observation of the transition from lasing driven by a bosonic to a fermionic reservoir in a GaAs quantum well microcavity 

    Brodbeck, S.; Suchomel, H.; Amthor, M.; Steinl, T.; Kamp, M.; Schneider, C.; Hoefling, Sven (2016-08-26) - Journal article
    We show that by monitoring the free carrier reservoir in a GaAs-based quantum well microcavity under non-resonant pulsed optical pumping, lasing supported by a fermionic reservoir (photon lasing) can be distinguished from ...
  • Observation of ultrafast free carrier dynamics in single layer MoS2 

    Cabo, Antonija; Miwa, Jill; Grønborg, Signe; Riley, Jonathon Mark; Johannsen, Jens; Cacho, Cephise; Alexander, Oliver; Chapman, Richard; Springate, Emma; Grioni, Marco; Lauritsen, Jeppe; King, Phil; Hofmann, Philip; Ulstrup, Søren (2015-09-09) - Journal item
    The dynamics of excited electrons and holes in single layer (SL) MoS2 have so far been difficult to disentangle from the excitons that dominate the optical response of this material. Here, we use time- and angle-resolved ...
  • Observation-driven configuration of complex software systems 

    Sage, Aled (University of St Andrews, 2004-06) - Thesis
    The ever-increasing complexity of software systems makes them hard to comprehend, predict and tune due to emergent properties and non-deterministic behaviour. Complexity arises from the size of software systems and the ...
  • Observational signatures of massive star formation : an investigation of the environments in which they form, and the applicability of the paradigm of low-mass star formation 

    Johnston, Katharine G. (University of St Andrews, 2011-06-24) - Thesis
    This thesis presents both a study of the cluster-scale environments in which massive stars form, investigating in particular how the ionized gas in these regions relates to the molecular star-forming material, as well as ...
  • Observational signatures of self-destructive civilizations 

    Stevens, A.; Forgan, Duncan; James, J.O. (2015) - Journal article
