  • Trend to equilibrium for the Becker–Döring equations: an analogue of Cercignani's conjecture 

    Cañizo, JA; Einav, Amit; Lods, B (Mathematical Sciences PublishersAnalysis and PDE, 2017-08-01)
    We investigate the rate of convergence to equilibrium for subcritical solutions to the Becker–Döring equations with physically relevant coagulation and fragmentation coefficients and mild assumptions on the given initial ...

  • Trust in numbers 

    Spiegelhalter, David John (WileyJournal of the Royal Statistical Society. Series A: Statistics in Society, 2017-10-01)
    Those who value quantitative and scientific evidence are faced with claims both of a reproducibility crisis in scientific publication, and of a post-truth society abounding in fake news and alternative facts. Both issues ...

  • In situ accretion of gaseous envelopes on to planetary cores embedded in evolving protoplanetary discs 

    Coleman, Gavin AL; Papaloizou, John Christopher; Nelson, Richard P (Oxford University PressMONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2017-09-21)
    The core accretion hypothesis posits that planets with significant gaseous envelopes accreted them from their protoplanetary discs after the formation of rocky/icy cores. Observations indicate that such exoplanets exist ...

  • 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 ...

  • Phoretic Interactions Generically Induce Dynamic Clusters and Wave Patterns in Active Colloids. 

    Liebchen, Benno; Marenduzzo, Davide; Cates, Michael Elmhirst (Physical review letters, 2017-06-28)
    We introduce a representative minimal model for phoretically interacting active colloids. Combining kinetic theory, linear stability analyses, and a general relation between self-propulsion and phoretic interactions in ...

  • Function of bacteriophage G7C esterase tailspike in host cell adsorption. 

    Prokhorov, Nikolai S; Riccio, Cristian; Zdorovenko, Evelina L; Shneider, Mikhail M; Browning, Christopher; Knirel, Yuriy A; Leiman, Petr G; Letarov, Andrey V (Molecular microbiology, 2017-08)

  • A finite dimensional approach to Donaldson's J-flow 

    Dervan, Ruadhai; Keller, J
    Consider a projective manifold with two distinct polarisations $L_1$ and $L_2$. From this data, Donaldson has defined a natural flow on the space of Kähler metrics in $c_1$($L_1$), called the J-flow. The existence of a ...

  • Critical Exponents on Fortuin-Kasteleyn Weighted Planar Maps 

    Berestycki, Nathanael Edouard; Laslier, Benoit; Ray, Gourab (SpringerCOMMUNICATIONS IN MATHEMATICAL PHYSICS, 2017-10-01)
    In this paper we consider random planar maps weighted by the self-dual Fortuin--Kasteleyn model with parameter $q \in (0,4)$. Using a bijection due to Sheffield and a connection to planar Brownian motion in a cone we obtain ...

  • Quantum conditional query complexity 

    Sardharwalla, Imdad; Strelchuk, Sergii; Jozsa, Richard (Rinton PressQuantum Information and Computationhttp://www.rintonpress.com/journals/qicabstracts/qicabstracts17-78.html, 2017-06-01)
    We define and study a new type of quantum oracle, the quantum conditional oracle, which provides oracle access to the conditional probabilities associated with an underlying distribution. Amongst other properties, we (a) ...

  • Homological mirror symmetry for hypersurface cusp singularities 

    Keating, Ailsa Macgregor (SpringerSelecta Mathematica, 2017-06-03)
    We study versions of homological mirror symmetry for hypersurface cusp singularities and the three hypersurface simple elliptic singularities. We show that the Milnor fibres of each of these carries a distinguished Lefschetz ...

  • Comments on: High-dimensional simultaneous inference with the bootstrap 

    Lockhart, RA; Samworth, Richard John (Sociedad de Estadistica e Investigacion OperativaTest, 2017-12-01)
    We congratulate the authors on their stimulating contribution to the burgeoning high-dimensional inference literature. The bootstrap offers such an attractive methodology in these settings, but it is well-known that its ...

  • Synoptic-to-planetary scale wind variability enhances phytoplankton biomass at ocean fronts 

    Whitt, DB; Taylor, John Ryan; Lévy, M (American Geophysical UnionJournal of Geophysical Research: Oceans, 2017-06-01)
    In nutrient-limited conditions, phytoplankton growth at fronts is enhanced by winds, which drive upward nutrient fluxes via enhanced turbulent mixing and upwelling. Hence, depth-integrated phytoplankton biomass can be 10 ...

  • The structure of limit groups over hyperbolic groups 

    Groves, Daniel; Wilton, Henry John

  • A Yellow Polariton Condensate in a Dye Filled Microcavity 

    Cookson, T; Georgiou, K; Zasedatelev, A; Grant, RT; Virgili, T; Cavazzini, M; Galeotti, F; Clark, C; Berloff, Natalia G; Lidzey, DG; Lagoudakis, PG (WileyAdvanced Optical Materials, 2017-09-18)
    Polariton condensation in the yellow part of the visible spectrum from a planar organic semiconductor microcavity containing the molecular dye bromine-substituted boron-dipyrromethene is observed. This study provides ...

  • Cosmological solutions with gravitational particle production and nonzero curvature 

    Paliathanasis, A; Barrow, John David; Pan, S (American Physical SocietyPhysical Review D - Particles, Fields, Gravitation and Cosmology, 2017-05-26)
    In a homogeneous and isotropic universe with nonzero spatial curvature we consider the effects of gravitational particle production in the dynamics of the universe. We show that the dynamics of the universe in such a ...

  • The inclusion of two-loop SUSYQCD corrections to gluino and squark pole masses in the minimal and next-to-minimal supersymmetric standard model: SOFTSUSY3.7 

    Allanach, Benjamin Christopher; Martin, SP; Robertson, DG; Ruiz de Austri, R (ElsevierComputer Physics Communications, 2017-10)
    We describe an extension of the SOFTSUSY spectrum calculator to include two-loop supersymmetric QCD (SUSYQCD) corrections of order O(α s 2 ) to gluino and squark pole masses, either in the minimal supersymmetric standard ...

  • An empirical resistive-force theory for slender biological filaments in shear-thinning fluids 

    Riley, EE; Lauga, Eric Jean-Marie (American Physical SocietyPhysical Review E - Statistical, Nonlinear, Biological, and Soft Matter Physics, 2017-06-23)
    Many cells exploit the bending or rotation of flagellar filaments in order to self-propel in viscous fluids. While appropriate theoretical modeling is available to capture flagella locomotion in simple, Newtonian fluids, ...

  • Minimax optimal procedures for testing the structure of multidimensional functions 

    Aston, John Alexander; Autin, F; Claeskens, G; Freyermuth, J-M; Pouet, C

    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. ...
