  • Double-stranded coarse grained model for DNA: applications to supercoiling and denaturation 

    Gutiérrez Fosado, Yair Augusto (The University of Edinburgh, 2019-07-01)
    DNA supercoiling is the name given to the under or overwinding of the two strands of a DNA double helix. It is of great interest because it is relevant in several crucial biological processes. However, the principles ...
  • Rheology and flow properties of a deformable droplet suspension 

    Foglino, Martina (The University of Edinburgh, 2019-07-01)
    Concentrated suspensions of colloidal particles in a liquid solvent are often found in nature and industry. Familiar examples include ice cream, mayonnaise, paints and biological fluids such as blood. It is well known ...
  • Onset of gravitational collapse of colloidal gels: an optical microscopy study 

    Zhou, Xuemao (The University of Edinburgh, 2018-07-02)
    Colloidal gels are ubiquitous in daily life, such as paint. A colloidal gel can support its own weight for a finite delay time in gravity. This delay time sets the shelf life of many products. Hence, understanding the ...
  • Characterising weather and rotation on substellar worlds 

    Vos, Johanna Maria Catherine (The University of Edinburgh, 2019-07-01)
    Photometric variability monitoring is sensitive to atmospheric inhomogeneities as they rotate in and out of view, and is a key probe of atmospheric features in brown dwarfs and giant exoplanets. The population of young, ...
  • Automatation of decomposed multi-loop Feynman-graphs 

    Rippon, Tom Owen (The University of Edinburgh, 2010-11-25)
    This thesis is an investigation into the link between momentum space Feynman graph integrals under a henge decomposition and parametric representation of Feynman graph integrals under a sector decomposition. A program ...
  • Time-dependent ionisation of metals in the intergalactic medium 

    Reynolds, Simon (The University of Edinburgh, 2010-11-25)
    This thesis presents the results of a study into modelling the ionisation of heavy elements in the intergalactic medium (IGM) by solving the time-dependent ionisation rate equations. An algorithm has been developed which ...
  • Nonlinear laser microscopy for the study of virus–host interactions 

    Robinson, Iain Thomas (The University of Edinburgh, 2010-11-25)
    Biomedical imaging is a key tool for the study of host-pathogen interactions. New techniques are enhancing the quality and flexibility of imaging systems, particularly as a result of developments in laser technologies. ...
  • Gravitational geomicrobiology: biofilms and their mineral interactions under terrestrial and altered gravity 

    Nicholson, Natasha Elizabeth (The University of Edinburgh, 2018-11-29)
    Experiments with microbial biofilms in microgravity and simulated microgravity have revealed altered growth kinetics, but geomicrobial biofilms have not yet been studied in low gravity environments. No characterisation ...
  • Testing gravity in the local universe 

    McManus, Ryan (The University of Edinburgh, 2018-11-29)
    General relativity (GR) has stood as the most accurate description of gravity for the last 100 years, weathering a barrage of rigorous tests. However, attempts to derive GR from a more fundamental theory or to capture ...
  • Experimental investigation of acoustic characteristics of radiation and playing gestures for lip-excited musical instruments 

    López-Carromero, Amaya (The University of Edinburgh, 2018-11-29)
    The geometrical characteristics of acoustical radiation are of great importance in instrument design and synthesis, and multiple simplified models have been developed in the past to describe them. In this work two ...
  • Rare radiative and semileptonic B meson decays 

    Gratrex, James (The University of Edinburgh, 2018-11-29)
    Recent results at the LHCb and B-factory experiments have suggested that rare processes in B →Vγ and B → V ℓ¯ℓ decays, where V is a vector meson, show some deviation from Standard Model predictions. Although these anomalies ...
  • Study of magnetic fluctuations and ordering in uranium compounds by heat capacity and neutron scattering measurements 

    Entwisle, Oliver John (The University of Edinburgh, 2018-11-29)
    URhGe is the first ferromagnet discovered that shows superconductivity at ambient pressure. It shows a rich temperature-magnetic field phase diagram with a re-emergence of superconductivity at high magnetic field where ...
  • Optical studies of diatomic molecules at extreme conditions 

    Afonina, Veronika Semenovna (The University of Edinburgh, 2018-11-29)
    The formidable progress achieved in the research at extreme conditions led to important discoveries of many unusual and interesting physical and chemical phenomena. Materials with high compressibility were and still are ...
  • Microbiology and the limits to life in deep salts 

    Payler, Samuel Joseph (The University of Edinburgh, 2018-07-02)
    Deep subsurface evaporites are common terrestrial deep subsurface environments found globally. These deposits are known to host communities of halophilic organisms, some of which have been suggested to be millions of ...
  • Ultra-red galaxies 

    Lewis, Alexander John Robert (The University of Edinburgh, 2018-11-29)
    Dusty star-forming galaxies (DSFGs) are highly luminous (LFIR ≳ 10¹² L⊙), very distant (z ≳ 2.5) and ≳ 10× rarer then ‘normal’, NIR-selected (BzK), star-forming galaxies. Capable of producing a Mstars ≳ 10¹¹-M⊙ galaxy after ...
  • Applications of branching processes to cancer evolution and initiation 

    Nicholson, Michael David (The University of Edinburgh, 2018-11-29)
    There is a growing appreciation for the insight mathematical models can yield on biological systems. In particular, due to the challenges inherent in experimental observation of disease progression, models describing the ...
  • Sequential and incomplete fusion break-up reactions with 70 MeV ⁷Li 

    Davinson, Thomas (The University of Edinburgh, 1987)
