Phase separation and multibody effects in three-dimensional active Brownian particles
Francesco Turci, Nigel B. Wilding
Simulation studies of the phase diagram of repulsive active Brownian particles in three dimensions reveal that the region of motility-induced phase separation between a high and lo…
Evolution of the truncated disc and inner hot-flow of GX 339-4
P. Chainakun, W. Luangtip, A. J. Young +2
Aims. We study the changes in geometry of the truncated disc and the inner hot-flow of GX 339-4 by analyzing the Power SpectralDensity (PSD) extracted from six XMM-Newton observati…
Flexible confinement leads to multiple relaxation regimes in glassy colloidal liquids
Ian Williams, Erdal C. Oğuz, Paul Bartlettl +2
Understanding relaxation of supercooled fluids is a major challenge and confining such systems can lead to bewildering behaviour. Here we exploit an optically confined colloidal mo…
Agile Reactive Navigation for A Non-Holonomic Mobile Robot Using A Pixel Processor Array
Yanan Liu, Laurie Bose, Colin Greatwood +6
This paper presents an agile reactive navigation strategy for driving a non-holonomic ground vehicle around a preset course of gates in a cluttered environment using a low-cost pro…
Deep Reinforcement Learning for Tactile Robotics: Learning to Type on a Braille Keyboard
Alex Church, John Lloyd, Raia Hadsell +1
Artificial touch would seem well-suited for Reinforcement Learning (RL), since both paradigms rely on interaction with an environment. Here we propose a new environment and set of…
A practical model of twin-beam experiments for sub-shot-noise absorption measurements
Jason D. Mueller, Nigam Samantaray, Jonathan C. F. Matthews
Quantum-intensity-correlated twin beams of light can be used to measure absorption with precision beyond the classical shot-noise limit. The degree to which this can be achieved wi…
