Spin alignment and differential accretion in merging black-hole binaries
(Oxford University PressMonthly Notices of the Royal Astronomical Society, 2015-06-29)
Interactions between a supermassive black-hole binary and the surrounding accretion disc can both assist the binary inspiral and align the black-hole spins to the disc angular momentum. While binary migration is due to ...
Thin-sheet flow between coalescing bubbles
(Cambridge University PressJournal of Fluid Mechanics, 2015-05-20)
When two spherical bubbles touch, a hole is formed in the fluid sheet between them, and capillary pressure acting on its tightly curved edge drives an outward radial flow which widens the hole joining the bubbles. Recent ...
Interpreting a CMS excess in lljj+missing-transverse-momentum with the golden cascade of the minimal supersymmetric standard model
(American Physical SocietyPhysical Review D, 2015-06-29)
The CMS experiment recently reported an excess consistent with an invariant mass edge in opposite-sign same flavor (OSSF) leptons, when produced in conjunction with at least two jets and missing transverse momentum. We ...
Strictly continuous extension of functionals with linear growth to the space BV
(Oxford University PressThe Quarterly Journal of Mathematics, 2015-06-24)
In this paper, we prove that the integral functional F[u]: BV(Ω;ℝ^m) → ℝ defined by
F[u] := ∫_Ω f(x,u(x),∇u(x))dx + ∫_Ω ∫_1^0 f^∞ (x, u^θ (x), (d D^s u)/(d |D^s u|) (x)
is continuous over BV(Ω;ℝ^m), with respect to ...

Stratosphere-troposphere coupling in the Earth System: where next?

Cortical microtubule nucleation can organise the cytoskeleton of Drosophila oocytes to define the anteroposterior axis
(eLifeeLife, 2015-09-25)
Many cells contain non-centrosomal arrays of microtubules (MTs), but the assembly, organisation and function of these arrays are poorly understood. We present the first theoretical model for the non-centrosomal MT cytoskeleton ...
Disruption of SSP/VWI states by a stable stratification
(Cambridge University PressJournal of Fluid Mechanics, 2015-11-06)
We identify ‘minimal seeds’ for turbulence, i.e. initial conditions of the smallest possible total perturbation energy density Ec that trigger turbulence from the laminar state, in stratified plane Couette flow, the flow ...
The structure of optimal parameters for image restoration problems
(ElsevierJournal of Mathematical Analysis and Applications, 2015-09-16)
We study the qualitative properties of optimal regularisation parameters in variational models for image restoration. The parameters are solutions of bilevel optimisation problems with the image restoration problem as ...
The Hindered M1 Radiative Decay Υ(2S) → η_b(1S)γ from Lattice NRQCD
(APSPhysical Review D, 2015-11-03)
We present a calculation of the hindered M1 Υ(2S) → η_b(1S)γ decay rate using lattice nonrelativistic QCD. The calculation includes spin-dependent relativistic corrections to the NRQCD action through O(v⁶ ) in the quark’s ...
