    • On the emergence and evolution of jets and vortices in turbulent planetary atmospheres 

      Jougla, Thibault (University of St Andrews, 2019-06-25) - Thesis
      This thesis investigates the formation and evolution of jets and vortices in turbulent planetary atmospheres using a dual approach of high-resolution numerical simulations and novel laboratory experiments. A two-layer ...
    • Three dimensional MHD simulations of the dynamics and energetics of coronal flux tubes 

      Howson, Thomas Alexander (University of St Andrews, 2019-06-25) - Thesis
      In this thesis we present the results of three-dimensional MHD simulations of the evolution of magnetic flux tubes within the solar atmosphere. We consider the dynamics and energetics of coronal loops that are perturbed ...
    • Semigroup congruences : computational techniques and theoretical applications 

      Torpey, Michael (University of St Andrews, 2019-06-25) - Thesis
      Computational semigroup theory is an area of research that is subject to growing interest. The development of semigroup algorithms allows for new theoretical results to be discovered, which in turn informs the creation ...
    • Maser radiation from collisionless shocks 

      Speirs, D. C.; Ronald, K.; Phelps, A. D. R.; Koepke, M. E.; Cairns, Robert Alan; Rigby, A.; Cruz, F.; Trines, R. M. G. M.; Bamford, R.; Kellet, B. J.; Albertazzi, B.; Cross, J. E.; Fraschetti, F.; Graham, P.; Kozlowski, P. M.; Kuramitsu, Y.; Miniati, F.; Morita, T.; Oliver, M.; Reville, B.; Sakawa, Y.; Sarkar, S.; Spindloe, C.; Koenig, M.; Silva, L. O.; Lamb, D. Q.; Tzeferacos, P.; Lebedev, S.; Gregori, G.; Bingham, R. (2019) - Journal article
      This paper describes a model of electron energization and cyclotron-maser emission applicable to astrophysical magnetized collisionless shocks. It is motivated by the work of Begelman, Ergun and Rees [Astrophys. J. 625 , ...
    • Modelling the immune response to cancer : an individual-based approach accounting for the difference in movement between inactive and activated T cells 

      Macfarlane, Fiona R.; Lorenzi, Tommaso; Chaplain, Mark A. J. (2018-06) - Journal article
      A growing body of experimental evidence indicates that immune cells move in an unrestricted search pattern if they are in the pre-activated state, whilst they tend to stay within a more restricted area upon activation ...
