  • Dynamical tides in exoplanetary systems containing hot Jupiters: Confronting theory and observations 

    Chernov, SV; Ivanov, PB; Papaloizou, John Christopher (Oxford University PressMonthly Notices of the Royal Astronomical Society, 2017-09-11)
    We study the effect of dynamical tides associated with the excitation of gravity waves in an interior radiative region of the central star on orbital evolution in observed systems containing hot Jupiters. We consider ...

  • Dynamical α-cluster model of $^{16}$O 

    Halcrow, CJ; King, C; Manton, Nicholas Stephen (American Physical SocietyPhysical Review C, 2017-03-09)
    We calculate the low-lying spectrum of the $^{16}$O nucleus using an α-cluster model which includes the important tetrahedral and square configurations. Our approach is motivated by the dynamics of α-particle scattering ...

  • Dynamics of buoyant releases in confined spaces. 

    Barnett, Steven John. (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 1992-01-28)
    The flows that may result from the release of a buoyant fluid from a small source in a confined space are varied and complex, depending on the source characteristics, the confining geometry and container ventilation. ...

  • Dynamics of laterally confined marine ice sheets 

    Kowal, Katarzyna N; Pegler, Samuel S; Worster, Michael Grae (Cambridge University PressJournal of Fluid Mechanics, 2016-02-03)
    We present an experimental and theoretical study of the dynamics of laterally confined marine ice sheets in the natural limit in which the long, narrow channel into which they flow is wider than the depth of the ice. A ...

  • Dynamics of quasi-two-dimensional turbulent jets 

    Landel, Julien Rémy Dominique Gérard (University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsChurchill CollegeBP Institute, 2012-11-13)
    The study of quasi-two-dimensional turbulent jets is relevant to chemical reactors, the coking process in oil refinement, as well as rivers flowing into lakes or oceans. In the event of a spillage of pollutants into a ...

  • Early-time free-surface flow driven by a deforming boundary 

    Brasz, C Frederik; Arnold, Craig B; Stone, Howard A; Lister, John Ronald (Cambridge University PressJournal of Fluid Mechanics, 2015-02-24)
    When a solid boundary deforms rapidly into a quiescent liquid layer, a flow is in- duced that can lead to jet formation. An asymptotic analytical solution is presented for this flow, driven by a solid boundary deforming ...

  • Editorial: Understanding neural organization using statistical analysis and computational modelling: from single cells to large-scale networks 

    Budd, Julian; Cuntz, Hemann; Eglen, Stephen John; Krieger, Patrik (FrontiersFrontiers in Neuroanatomy, 2015-10-26)

  • Efficiency of turbulent mixing in the abyssal ocean circulation 

    Caulfield, Colm-cille Patrick; Mashayek, A; Salehipour, H; Bouffard, D; Ferrari, R; Peltier, W; Smyth, W; Nikurashin, M (American Geophysical UnionGeophysical Research Letters, 2017-07-17)
    Turbulent mixing produced by breaking of internal waves plays an important role in setting the patterns of downwelling and upwelling of deep dense waters and thereby helps sustain the global deep ocean overturning circulation. ...

  • Efficient boundary integral solution for acoustic wave scattering by irregular surfaces 

    Rath-Spivack, Orsola; Spivack, Mark (ElsevierEngineering Analysis with Boundary Elements, 2017-10-01)
    The left–right operator splitting method is studied for the efficient calculation of acoustic fields scattered by arbitrary rough surfaces. Here, the governing boundary integral is written as a sum of left- and right-going ...

  • Efficient mixing in stratified flows: experimental study of a Rayleigh-Taylor unstable interface within an otherwise stable stratification 

    Davies-Wykes, Megan S; Dalziel, Stuart Bruce (Cambridge University PressJournal of Fluid Mechanics, 2014-09-09)
    Boussinesq salt-water laboratory experiments of Rayleigh–Taylor instability (RTI) can achieve mixing efficiencies greater than 0.75 when the unstable interface is confined between two stable stratifications. This is much ...

  • Einstein–Weyl spaces and near-horizon geometry 

    Dunajski, Maciej Lukasz; Gutowski, J; Sabra, W (IOP PublishingClassical and Quantum Gravity, 2017-02-02)
    We show that a class of solutions of minimal supergravity in five dimensions is given by lifts of three-dimensional Einstein–Weyl structures of hyper-CR type. We characterise this class as most general near-horizon limits ...

  • Elasticity and Glocality: Initiation of Embryonic Inversion in Volvox 

    Haas, Pierre; Goldstien, Raymond E (Royal Society PublishingJournal of the Royal Society Interface, 2015-10-21)
    Elastic objects across a wide range of scales deform under local changes of their intrinsic properties, yet the shapes are glocal, set by a complicated balance between local properties and global geometric constraints. ...

  • Elastocapillarity: adhesion and large deformations of thin sheets 

    Wagner, Till Jakob Wenzel (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2013-09-03)
    This thesis is concerned with the deformation and adhesion of thin elastic sheets that come into contact with an underlying substrate. The focus of this work is on the interplay between material and geometric properties ...

  • Elastohydrodynamic synchronization of adjacent beating flagella 

    Goldstein, Raymond Ethan; Lauga, Eric Jean-Marie; Pesci, Adriana Irma; Proctor, Michael Richard (American Physical SocietyPhysical Review Fluids, 2016-11-01)
    It is now well established that nearby beating pairs of eukaryotic flagella or cilia typically synchronize in phase. A substantial body of evidence supports the hypothesis that hydrodynamic coupling between the active ...

  • Electromagnetic transition strengths for light nuclei in the Skyrme model 

    Haberichter, M; Lau, PHC; Manton, Nicholas Stephen (American Physical SocietyPhysical Review C, 2016-03-07)
    We calculate reduced B(E2) electromagnetic transition strengths for light nuclei of mass numbers B = 8,12,16,20,24, and 32 within the Skyrme model. We find that the predicted transition strengths are of the correct order ...

  • Emission-angle and polarization-rotation effects in the lensed CMB 

    Lewis, A; Hall, A; Challinor, Anthony David
    Lensing of the CMB is an important effect, and is usually modelled by remapping the unlensed CMB fields by a lensing deflection. However the lensing deflections also change the photon path so that the emission angle is no ...

    Pacini, Clare; Ajioka, JW; Micklem, Gos (BioMed CentralBMC Bioinformatics, 2017-04-12)

  • End point of Black Ring Instabilities and the Weak Cosmic Censorship Conjecture 

    Figueras, Pau; Kunesch, Markus; Tunyasuvunakool, Saran (American Physical SocietyPhysical Review Letters, 2016-02-18)
    We produce the first concrete evidence that violation of the weak cosmic censorship conjecture can occur in asymptotically flat spaces of five dimensions by numerically evolving perturbed black rings. For certain thin ...

    Figueras, P; Kunesch, Markus; Lehner, L; Tunyasuvunakool, Saran (American Physical SocietyAmerican Physical SocietyPhysical Review Letters, 2017-04-14)
    We determine the end point of the axisymmetric ultraspinning instability of asymptotically flat Myers-Perry black holes in D = 6 spacetime dimensions. In the nonlinear regime, this instability gives rise to a sequence of ...
