Electromagnetic interactions in a pair of coupled split-ring resonators
(American Physical Society, 2017)Split-ring Resonators (SRRs) are a fundamental building block of many electromagnetic metamaterials. Typically the response of a metamaterial is assumed to be independent of inter-element interactions in the material. We ... -
Heteroatom-doped porous carbons with enhanced carbon dioxide uptake and excellent methylene blue adsorption capacities
(Elsevier for International Zeolite Association, 2017)Heteroatom nitrogen and oxygen-doped porous carbon materials were for the first time generated via a one-pot carbonization of metal-organic framework under argon saturated water steam at an elevated temperature. The water ... -
From coupled networks of systems to networks of states in phase space
(American Institute of Mathematical Sciences (AIMS), 2017)Dynamical systems on graphs can show a wide range of behaviours beyond simple synchronization - even simple globally coupled structures can exhibit attractors with intermittent and slow switching between patterns of ... -
Gonadotropin-releasing hormone signaling: An information theoretic approach
(Elsevier, 2017-07-29)Gonadotropin-releasing hormone (GnRH) is a peptide hormone that mediates central control of reproduction, acting via G-protein coupled receptors that are primarily Gq coupled and mediate GnRH effects on the synthesis and ... -
Advection of potential temperature in the atmosphere of irradiated exoplanets: a robust mechanism to explain radius inflation
(American Astronomical Society / IOP Publishing, 2017)The anomalously large radii of strongly irradiated exoplanets have remained a major puzzle in astronomy. Based on a 2D steady state atmospheric circulation model, the validity of which is assessed by comparison to 3D ... -
Reactive Control of a Wave Energy Converter using Artificial Neural Networks
(Elsevier, 2017)A model-free algorithm is developed for the reactive control of a wave energy converter. Arti cial neural networks are used to map the signi cant wave height, wave energy period, and the power take-o damping and sti ... -
Absence of Anderson localization in certain random lattices
(American Physical Society, 2017-08-10)We report on the transition between an Anderson localized regime and a conductive regime in a one-dimensional microwave scattering system with correlated disorder. We show experimentally that when long-range correlations ... -
Automatic shape optimisation of the turbine-99 draft tube
(OpenFOAM, 2017-07)INTRODUCTION The performance of a hydraulic reaction turbine is significantly affected by the efficiency of its draft tube. Factors which impede the tube’s performance include the geometrical shape (profile), and velocity ... -
Shape optimisation using Computational Fluid Dynamics and Evolutionary Algorithms
(OpenDOAM, 2016-06)Optimisation of designs using Computational Fluid Dynamics (CFD) are frequently performed across many fields of research, such as the optimisation of an aircraft wing to reduce drag, or to increase the efficiency of a ... -
A highly attenuating and frequency tailorable annular hole phononic crystal for surface acoustic waves
(Springer Nature, 2017-08-02)Surface acoustic wave (SAW) devices are widely used for signal processing, sensing and increasingly for lab-on-a-chip applications. Phononic crystals can control the propagation of SAW, analogous to photonic crystals, ... -
Theory of Linear Spin Wave Emission from a Bloch Domain Wall
(American Physical Society, 2017)We report an analytical theory of linear emission of exchange spin waves from a Bloch domain wall, excited by a uniform microwave magnetic field. The problem is reduced to a one-dimensional Schr\"odinger-like equation with ... -
Systematic Review and Meta-Analysis of Randomised Trials to Ascertain Fatal Gastrointestinal Bleeding Events Attributable to Preventive Low-Dose Aspirin: No Evidence of Increased Risk
(Public Library of Science, 2016-11-15)Background Aspirin has been shown to lower the incidence and the mortality of vascular disease and cancer but its wider adoption appears to be seriously impeded by concerns about gastrointestinal (GI) bleeding. Unlike ... -
Integrating technology into complex intervention trial processes: a case study
(BioMed Central, 2016-11-17)Background Trials of complex interventions are associated with high costs and burdens in terms of paperwork, management, data collection, validation, and intervention fidelity assessment occurring across multiple sites. ... -
Physical Activity Self-Management and Coaching Compared to Social Interaction in Huntington Disease: Results From the ENGAGE-HD Randomized, Controlled Pilot Feasibility Trial
(Oxford University Press (OUP) / American Physical Therapy Association (APTA), 2017-03-24)Background. Self-management and self-efficacy for physical activity is not routinely considered in neurologic rehabilitation. Objective. This study assessed feasibility and outcomes of a 14-week physical activity ... -
Architecture design study and technology roadmap for the Planet Formation Imager (PFI)
(Society of Photo-optical Instrumentation Engineers (SPIE), 2016-08-04)The Planet Formation Imager (PFI) Project has formed a Technical Working Group (TWG) to explore possible facility architectures to meet the primary PFI science goal of imaging planet formation in situ in nearby starforming ... -
Co-phasing the Planet Formation Imager
(Society of Photo-optical Instrumentation Engineers (SPIE), 2016-08-04)The Planet Formation Imager (PFI) is a project for a very large optical interferometer intended to obtain images of the planet formation process at scales as small as the Hill sphere of giant exoplanets. Its main science ... -
Orbits, Distance, and Stellar Masses of the Massive Triple Star Sigma Orionis
(American Astronomical Society / IOP Publishing, 2016-12-05)We present interferometric observations of the σ Orionis triple system using the CHARA Array, NPOI, and VLTI. Using these measurements, we spatially resolve the orbit of the close spectroscopic binary (Aa,Ab) for the first ... -
