Gravity-dominated unequal-mass black hole collisions
(APSPhysical Review D, 2016-02-04)
We continue our series of studies of high-energy collisions of black holes investigating unequalmass, boosted head-on collisions in four dimensions. We show that the fraction of the center-of-mass energy radiated as ...
Vortices and Monopoles in a Harmonic Trap
(SpringerJournal of High Energy Physics, 2015-12-15)
The Ω-deformation is a harmonic trap, penning certain excitations near the origin in a manner consistent with supersymmetry. Here we explore the dynamics of BPS monopoles and vortices in such a trap. We pay particular ...
Exploiting the Feller Coupling for the Ewens Sampling Formula

Homeostatic Activity-Dependent Tuning of Recurrent Networks for Robust Propagation of Activity
(Society for NeuroscienceJournal of Neuroscience, 2016-03-30)
Developing neuronal networks display spontaneous bursts of action potentials that are necessary for circuit organization and tuning. While spontaneous activity has been shown to instruct map formation in sensory circuits, ...
Structured light enables biomimetic swimming and versatile locomotion of photoresponsive soft microrobots
(Nature Publishing GroupNature Materials, 2016-02-15)
Microorganisms move in challenging environments by periodic changes in body shape. In contrast, current artificial microrobots cannot actively deform, exhibiting at best passive bending under external fields. Here, by ...
Dynamics of laterally confined marine ice sheets
(Cambridge University PressJournal of Fluid Mechanics, 2016-02-03)
We present an experimental and theoretical study of the dynamics of laterally confined marine ice sheets in the natural limit in which the long, narrow channel into which they flow is wider than the depth of the ice. A ...
Quantum communication complexity advantage implies violation of a Bell inequality
(National Academy of SciencesProceedings of the National Academy of Sciences, 2016-03-08)
We obtain a general connection between a large quantum advantage in communication complexity and Bell non-locality. We show that given any protocol offering a sufficiently large quantum advantage in communication complexity, ...
Assessment of ice flow dynamics in the zone close to the calving front of Antarctic ice shelves
(International Glaciological SocietyJournal of Glaciology, 2015-12-01)
We investigate the relationship between four ice-shelf characteristics in the area close to the calving front: ice flow speed, strain rate, ice thickness and shelf width. Data are compiled for these glaciological parameters ...
The response of the lower stratosphere to zonally symmetric thermal and mechanical forcing.
(American Meteorological SocietyJournal of the Atmospheric Sciences, 2016-04-15)
The response of the atmosphere to zonally symmetric applied heating and mechanical forcing is considered, allowing for the fact that the response may include a change in the wave force (or ‘wave drag’). A scaling argument ...
The double peak in upwelling and heating in the tropical lower stratosphere.
(American Meteorological SocietyJournal of the Atmospheric Sciences, 2016-04-15)
The processes responsible for double peak latitudinal structures in the time averaged tropical lower stratospheric upwelling, centred near 70hPa and 20º N–S, previously noted in ERA-Interim and other reanalysis and model ...
