  • 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 ...

    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 ...

  • Automatic Inference of Code Transforms and Search Spaces for Automatic Patch Generation Systems 

    Unknown author (2016-07-08)
    We present a new system, Genesis, that processes sets of human patches to automatically infer code transforms and search spaces for automatic patch generation. We present results that characterize the effectiveness of the ...

  • 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
    We present a novel method for detecting some structural characteristics of multidimensional functions. We consider the multidimensional Gaussian white noise model with an anisotropic estimand. Using the relation between ...

  • Planning Robust Strategies for Constructing Multi-object Arrangements 

    Unknown author (2017-01-30)
    A crucial challenge in robotics is achieving reliable results in spite of sensing and control uncertainty. A prominent strategy for dealing with uncertainty is to construct a feedback policy, where actions are chosen as a ...

  • 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. ...

  • Inference and Regeneration of Programs that Store and Retrieve Data 

    Unknown author (2017-04-24)
    As modern computation platforms become increasingly complex, their programming interfaces are increasingly difficult to use. This complexity is especially inappropriate given the relatively simple core functionality that ...
