(EDP Sciences for European Southern Observatory (ESO), 2018-09-25)This is an erratum for Exploring the climate of Proxima B with the Met Office Unified Model, published in Astronomy & Astrophysics Vol. 601, article A120 (2017), DOI: 10.1051/0004-6361/201630020 -
Of Mice and Dementia: A filmed conversation on the use of animals in dementia research
(SAGE Publications, 2018)Preclinical science research focuses on the study of physiological systems regulating body functions, and how they are dysregulated in disease, in a non-human setting. For example, cells in a dish, computer simulations ... -
Extension of the modified effective medium approach to nanocomposites with anisotropic thermal conductivities
(American Physical Society, 2018-09-10)An extended modification of the effective medium approach (emEMA) has been developed for the thermal conductivity of anisotropic nanocomposites. This is based on extending approaches developed to treat an anisotropic ... -
Investigation of the coupling between tunable split-ring resonators (dataset)
(University of Exeter, 2018-10-11)This is the dataset used for the Baraclough et al. (2018) article "Investigation of the coupling between tunable split-ring resonators" published in Physical Review B: condensed matter and materials physics. -
The path towards high-contrast imaging with the VLTI: the Hi-5 project
(Springer Verlag, 2018-06-20)The development of high-contrast capabilities has long been recognized as one of the top priorities for the VLTI. As of today, the VLTI routinely achieves contrasts of a few 10− 3in the near-infrared with PIONIER (H band) ... -
A geometrical 1% distance to the short-period binary Cepheid V1334 Cygni
(American Astronomical Society / IOP Publishing, 2018)Cepheid stars play a considerable role as extragalactic distances indicators, thanks to the simple empirical relation between their pulsation period and their luminosity. They overlap with that of secondary distance ... -
Molecular dynamics simulations disclose early stages of the photo-activation of cryptochrome 4 (dataset)
(University of Exeter, 2018-09-28)Birds appear to be equipped with a light-dependent, radical-pair-based magnetic compass that relies on truly quantum processes. While the identity of the sensory protein has remained speculative, cryptochrome 4 has recently ... -
Magnetic interfaces as sources of coherent spin waves
(American Physical Society, 2018-09-14)We have developed a simple but general analytical theory that elucidates the mechanism of spin-wave generation from interfaces between ferromagnetic media pumped by a uniform microwave magnetic field. Our calculations show ... -
On the origin of magnetic fields in stars
(Oxford University Press (OUP) / Royal Astronomical Society, 2018-09-05)Are the kG-strength magnetic fields observed in young stars a fossil field left over from their formation or are they generated by a dynamo? We use radiation non-ideal magnetohydrodynamics simulations of the gravitational ... -
Superdirectivity from arrays of strongly coupled meta-atoms
(AIP Publishing, 2018-09-10)We explore the possibility of achieving superdirectivity in metamaterial-inspired endfire antenna arrays relying on the good services of magnetoinductive waves. These are short-wavelength slow waves propagating by virtue ... -
Graphene electronic fibres with touch-sensing and light-emitting functionalities for smart textiles
(Springer Nature, 2018-09-25)The true integration of electronics into textiles requires the fabrication of devices directly on the fibre itself using high performance materials that allow seamless incorporation into fabrics. Woven electronics and ... -
Hyperspectral Analysis Applied to Micro-Brillouin Maps of Amyloid-Beta Plaques in Alzheimer’s Brain
(Royal Society of Chemistry, 2018)A recent investigation in the architecture and chemical composition of amyloid-β (Aβ) plaques in ex vivo histological sections of an Aβ-overexpressing transgenic mouse hippocampus, has shed light onto the infrared light ... -
Graphene-based light sensing: fabrication, characterisation, physical properties and performance
(MDPI, 2018-09-18)Graphene and graphene-based materials exhibit exceptional optical and electrical properties with great promise for novel applications in light detection. However, several challenges prevent the full exploitation of these ... -
Magnetic Field-Sensitive Radical Pair Dynamics in Polymethylene Ether-Bridged Donor–Acceptor Systems
(American Chemical Society, 2018-08-31)Donor–acceptor systems forming exciplexes are versatile models for the study of magnetic field effects (MFEs) on charge recombination reactions. The MFEs originate from singlet–triplet interconversion within transient ... -
Hall effect-driven formation of gravitationally unstable discs in magnetized molecular cloud cores (article)
(Oxford University Press (OUP) / Royal Astronomical Society, 2018-08-17)We demonstrate the formation of gravitationally unstable discs in magnetized molecular cloud cores with initial mass-to-flux ratios of five times the critical value, effectively solving the magnetic braking catastrophe. ... -
Electric-field control of spin-wave power flow and caustics in thin magnetic films
(American Physical Society, 2018-07-26)An external electric field can modify the strength of the spin-orbit interaction between spins of ions in magnetic crystals. This influence leads to a spin-wave frequency shift that is linear in both the applied electric ... -
Magnonic band spectrum of spin waves in an elliptical helix
(Royal Society, 2018-01-31)We show that the spin-wave spectrum in an elliptical helix has a band character. The size of the first band gap calculated using the perturbation theory is shown to scale as square root of the eccentricity. Curved magnonic ... -
A Contaminant-Free Catalogue of Gaia DR2-WISE Galactic Plane Matches: Including the Effects of Crowding in the Cross-Matching of Photometric Catalogues (article)
(Oxford University Press (OUP) / Royal Astronomical Society, 2018-09-03)Faint, hidden contaminants in the point-spread functions (PSFs) of stars cause shifts to their measured positions. Wilson & Naylor (2017) showed failing to account for these shifts can lead to a drastic decrease in the ... -
