Elasticity and Glocality: Initiation of Embryonic Inversion in Volvox
(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. ...
The third way to 3D gravity
(World ScientificInternational Journal of Modern Physics D, 2015-10-09)
Consistency of Einstein’s gravitational field equation Gµν ∝ Tµν imposes a “conservation condition” on the T-tensor that is satisfied by (i) matter stress tensors, as a consequence of the matter equations of motion, and ...
Twistor form of massive 6D superparticle
(IOP ScienceJournal of Physics A, 2015-12-16)
The massive six-dimensional (6D) superparticle with manifest (n, 0) supersymmetry is shown to have a supertwistor formulation in which its “hidden” (0, n) supersymmetry is also manifest. The mass-shell constraint is replaced ...
Separable projection integrals for higher-order correlators of the cosmic microwave sky: Acceleration by factors exceeding 100
(ElsevierJournal of Computational Physics, 2016-01-19)
We present a case study describing efforts to optimise and modernise “Modal”, the simulation and analysis pipeline used by the Planck satellite experiment for constraining general non-Gaussian models of the early universe ...
Three-dimensional flow in Kupffer's Vesicle
(SpringerJournal of Mathematical Biology, 2016-01-29)
Whilst many vertebrates appear externally left-right symmetric, the arrangement of internal organs is asymmetric. In zebrafish, the breaking of left-right symmetry is organised by Kupffer’s Vesicle (KV): an approximately ...
Using stratification to mitigate end-effects in quasi-Keplerian Taylor-Couette flow
(Cambridge University PressJournal of Fluid Mechanics, 2016-02-24)
Efforts to model accretion disks in the laboratory using Taylor–Couette flow apparatus are plagued with problems due to the substantial impact the end-plates have on the flow. We explore the possibility of mitigating the ...
Linear and nonlinear wave propagation in booming sand dunes
(AIPPhysics of Fluids, 2015-10-27)
The current field study examines linear and non-linear acoustic waves found in large desert sand dunes using field measurements of wave speed, frequency content, dispersion, and polarization. At the dune fields visited, ...
ATLAS diboson excess could be an R-parity violating dismuon excess
(American Physical SocietyPhysical Review D, 2016-02-09)
We propose a new possible explanation of the ATLAS diboson excess: that it is due to heavy resonant slepton production, followed by decay into dismuons. The smuon has a mass not too far from the W and Z masses, and so it ...
