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 ...
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 ...
On superconformal anyons
(SpringerJournal of High Energy Physics, 2016-01-22)
In d = 2+1 dimensions, there exist field theories which are non-relativistic and superconformal. These theories describe two species of anyons, whose spins differ by 1/2, interacting in a harmonic trap. We compute the ...
Acoustic Scattering by a Finite Rigid Plate with a Poroelastic Extension
(Cambridge University PressJournal of Fluid Mechanics, 2016-02-24)
The scattering of sound by a finite rigid plate with a finite poroelastic extension interacting with an unsteady acoustic source is investigated to determine the effects of porosity, elasticity, and the length of the ...
Investigating prominence turbulence with Hinode SOT Dopplergrams
(EDP SciencesAstronomy & Astrophysics, 2016-10-10)
Quiescent prominences host a diverse range of flows, including Rayleigh-Taylor instability driven upflows and impulsive downflows, and so it is no surprise that turbulent motions also exist. As prominences are believed to ...
A model for the effects of germanium on silica biomineralization in choanoflagellates
(Royal Society PublishingJournal of the Royal Society Interface, 2016-09-21)
Silica biomineralization is a widespread phenomenon of major biotechnological interest. Modifying biosilica with substances like germanium (Ge) can confer useful new properties, although exposure to high levels of Ge ...
