Instabilities and transport in magnetized plasmas
(University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsDarwin College, 2011-02-08)In a magnetized plasma, naturally occurring pressure anisotropies facilitate in- stabilities that are expected to modify the transport properties of the system. In this thesis we examine two such instabilities and, where ...

Multi-Contrast MRI Reconstruction with Structure-Guided Total Variation
(Society for Industrial and Applied MathematicsSIAM Journal on Imaging Sciences, 2016-08-04)Magnetic resonance imaging (MRI) is a versatile imaging technique that allows different contrasts depending on the acquisition parameters. Many clinical imaging studies acquire MRI data for more than one of these contrasts—such ...
