Improved Raindrop Detection using Combined Shape and Saliency Descriptors with Scene Context Isolation - Evaluation Dataset

Toby P. Breckon & Dereck D. Webster
The presence of raindrop induced image distortion has a significant negative impact on the performance of a wide range of all-weather visual sensing applications including within the increasingly import contexts of visual surveillance and vehicle autonomy. A key part of this problem is robust raindrop detection such that the potential for performance degradation in effected image regions can be identified. Here we address the problem of raindrop detection in colour video imagery using an extended...

Manfred Yu Thesis data

Manfred Man Hoi Yu
This thesis presents the work towards the realisation of an interferometer using bright solitary waves in a ring. The splitting of a bright solitary wave, which is created from a 85Rb Bose-Einstein condensate in an optical waveguide, is realised through scattering from a narrow potential well formed from a tightly focussed red detuned laser beam. We observe reflection of up to 25% of the atoms, along with the trapping of atoms at the position of...

A tunable CW UV laser with <35kHz absolute frequency instability for precision spectroscopy of Sr Rydberg states: supporting data

Elizabeth M. Bridge, Niamh C. Keegan, Alistair D. Bounds, Danielle Boddy, Daniel P. Sadler & Matthew P. A. Jones
We present a solid-state laser system that generates over 200 mW of continuous-wave, narrowband light, tunable from 316.3 nm - 317.7 nm and 318.0 nm - 319.3 nm. The laser is based on commercially available fiber amplifiers and optical frequency doubling technology, along with sum frequency generation in a periodically poled stoichiometric lithium tantalate crystal. The laser frequency is stabilized to an atomic-referenced high finesse optical transfer cavity. Using a GPS-referenced optical frequency comb we...

Sildenafil citrate data bundle

Paul Hodgkinson
A combination of solid-state NMR techniques, including 13C/1H correlation, 2H magic-angle spinning NMR and first principles calculation are employed to characterise the role of water in different hydration states of sildenafil citrate. The 13C spectrum is fully assigned for the first time and direct correlations made with respect to the crystal structure. 2H magic-angle spinning NMR is demonstrated to be a powerful tool for the study of dynamic and exchange processes in complex hydrate systems,...

Data Supporting "Interfacial contribution to thickness dependent in-plane anisotropic magnetoresistance", AIP Advances 5, 127108 (2015)

Mustafa Tokac, Mu Wang, Samridh Jaiswal, Andrew Rushforth, Bryan Gallagher, Del Atkinson & Aidan Hindmarch
(Abstract from article) We have studied in-plane anisotropic magnetoresistance(AMR) in cobaltfilms with overlayers having designed electrically interface transparency. With an electrically opaque cobalt/overlayer interface, the AMR ratio is shown to vary in inverse proportion to the cobaltfilm thickness; an indication that in-plane AMR is a consequence of anisotropic scattering with both volume and interfacial contributions. The interface scattering anisotropy opposes the volume scattering contribution, causing the AMR ratio to diminish as the cobaltfilm thickness is...

Data for "Enhanced optical cross section via collective coupling of atomic dipoles in a 2D array"

Robert J. Bettles
Enhancing the optical cross section is an enticing goal in light-matter interactions, due to its fundamental role in quantum and non-linear optics. Here, we show how dipolar interactions can suppress off-axis scattering in a two-dimensional atomic array, leading to a subradiant collective mode where the optical cross section is enhanced by almost an order of magnitude. As a consequence, it is possible to attain an optical depth which implies high fidelity extinction, from a monolayer....

Robust NMR water signal suppression for demanding analytical applications

Juan A. Aguilar & Simon J. Kenwright
We describe the design and application of robust, general-purpose water signal suppression pulse sequences well suited to chemometric work. Such pulse sequences need to deal well with pulse mis-calibrations, radiation damping, chemical exchange, and the presence of sample inhomogeneities, as well as with significant variations in sample characteristics such as pH, ionic strength, relaxation characteristics and molecular weight. Of course, such pulse sequences should produce un- distorted lineshapes and baselines and work well both under...

Metadata for 'Long lifetime hole traps at grain boundaries in CdTe thin-film photovoltaics'

Budhika Mendis
A novel time-resolved cathodoluminescence method, where a pulsed electron beam is generated via the photoelectric effect, is used to probe individual CdTe grain boundaries. Excitons have a short lifetime (100 ps) within the grains and are rapidly quenched at the grain boundary. However, a ~47 meV shallow acceptor, believed to be due to oxygen, can act as a long lifetime hole trap, even at the grain boundaries where their concentration is higher. This provides direct...

Observation of interference effects via four photon excitation of highly excited Rydberg states in thermal cesium vapor (Data files)

Jorge M. Kondo, Nikola Šibalić, Alex Guttridge, Christopher G. Wade, Natalia R. De Melo, Charles S. Adams & Kevin J. Weatherill
We report on the observation of Electromagnetically Induced Transparency (EIT) and Absorption (EIA) of highly-excited Rydberg states in thermal Cs vapor using a 4-step excitation scheme. The advantage of this 4-step scheme is that the final transition to the Rydberg state has a large dipole moment and one can achieve similar Rabi frequencies to 2 or 3 step excitation schemes using two orders of magnitude less laser power. Consequently each step is driven by a...

Data from "Spectroscopic detection of atom-surface interactions in an atomic-vapor layer with nanoscale thickness"

Kate Whittaker, James Keaveney, Charles S Adams & Ifan Hughes
Abstract from paper: We measure the resonance line shape of atomic-vapor layers with nanoscale thickness confined between two sapphire windows. The measurement is performed by scanning a probe laser through resonance and collecting the scattered light. The line shape is dominated by the effects of Dicke narrowing, self-broadening, and atom-surface interactions. By fitting the measured line shape to a simple model we discuss the possibility to extract information about the atom-surface interaction.

Data Supporting "Interfacial Structure Dependent Spin Mixing Conductance in Cobalt Thin Films", Physical Review Letters 115, 056601 (2015)

Mustafa Tokac, Sergiy Bunyaev, Gleb Kakazei, David Schmool, Del Atkinson & Aidan Hindmarch
Enhancement of Gilbert damping in polycrystalline cobalt thin-film multilayers of various thicknesses, overlayered with copper or iridium, was studied in order to understand the role of local interface structure in spinpumping. X-ray diffraction indicates that cobalt films less than 6 nm thick have strong fcc(111) texture while thicker films are dominated by hcp(0001) structure. The intrinsic damping for cobalt thicknesses above 6 nm is weakly dependent on cobalt thickness for both overlayer materials, and below...

Measuring the disorder of vortex lattices in a Bose-Einstein condensate: supporting data

A. Rakonjac, A. L. Marchant, T. P. Billam, J. L. Helm, M. M. H. Yu, S. A. Gardiner & S. L. Cornish
We report observations of the formation and subsequent decay of a vortex lattice in a Bose-Einstein condensate confined in a hybrid optical-magnetic trap. Vortices are induced by rotating the anharmonic magnetic potential that provides confinement in the horizontal plane. We present simple numerical techniques based on image analysis to detect vortices and analyse their distributions. We use these methods to quantify the amount of order present in the vortex distribution as it transitions from a...

Furosemide - isonicotinamide cocrystals: An investigation of properties and structural disorder

Hannah E. Kerr, Lorna Softley, Kuthuru Suresh, Ashwini Nangia, Paul Hodgkinson & Ivana Radosavljevic Evans
Abstract from article: Furosemide is a loop diuretic drug marketed in solid form which suffers from low solubility and low permeability. The pharmaceutically relevant properties of a recently described furosemide-isonicotinamide 2:1 cocrystal (2FS-INA) were investigated and compared with those of other known furosemide cocrystals. The intrinsic dissolution rate of 2FS-INA was found to be 1.27 times that of the commercial FS, while the equilibrium solubility of 2FS-INA is 5.6 times higher than that of pure...

The apparatus consists of a dual species effusive oven source, dual species Zeeman slower, magneto-optical traps in a single ultra-high vacuum science chamber, and the associated laser systems. The dual species Zeeman slower is used to load sequentially the two species into their respective traps. Its design is flexible and may be adapted for other experiments with different...

Why do Animal Eyes have Pupils of Different Shapes? (Data Files)

Gordon Love
There is a striking correlation between terrestrial species' pupil shape and ecological niche (i.e., foraging mode and time of day they are active). Species with vertically elongated pupils are very likely to be ambush predators and active day and night. Species with horizontally elongated pupils are very likely to be prey and to have laterally placed eyes. Vertically elongated pupils create astigmatic depth of field such that images of vertical contours nearer or farther than...
