Tracing Wyville Thomson Ridge Overflow Water in the Rockall Trough
… waters from the Nordic Seas overflow the Wyville Thomson Ridge, the water masses' subsequent pathways and fate have been uncertain. This study conclusively places Wyville Thomson Ridge Overflow Water (WTOW) as an important water mass in the eastern subpolar North Atlantic for the first time. Using …

Functional Characterisation of a RECQL4 Mutation in Rothmund-Thomson Syndrome
… the RECQL4 DNA helicase cause Type II Rothmund-Thomson syndrome (RTS), a human disease characterised by defects in skeletal development and predisposition to specific types of cancer, including osteosarcoma (OS). RECQL4 has been implicated in multiple cellular functions that mediate accurate DNA …

Compact laser-driven electron acceleration, bunch compression and coherent nonlinear Thomson scattering
… of coherent hard x-ray radiation by nonlinear Thomson scattering of compressed electron bunches. The Lawson-Woodward theorem describes conditions prohibiting net electron acceleration in laser-electron interactions. We point out how the Lawson-Woodward theorem permits net linear acceleration of …

Increased Oxidative Phosphorylation In An Ipsc- Derived Model of Rothmund-Thomson Syndrome Associated Osteosarcomagenesis
… worldwide. Patients with Type II Rothmund-Thomson Syndrome (RTS) are highly predisposed to develop osteosarcoma, with 30% of patients in the largest cohort study developing osteosarcoma. Patients with Type II RTS have biallelic mutations in the DNA helicase RECQL4, which has been shown to …

Picturing the World's news: news photography, culturalproduction, Thomson Reuters and the international processof news making
… the production process of news pictures at Thomson Reuters international multimedia news agency is examined along its ‘local’ and ‘international’ key moments and sites, and the career of Reuters photographs- from the moment they are conceived as ideas to their purchase- is followed and …

Target-directed Locomotion: A Critique Of The Short-term Memory For Spatial Locations Proposed By Thomson
… short-term memory for target locations (Thomson, 1980, 1983). No evidence of such an accurate short-term memory was found here. The distance to the target, not the elapsed time, affected accuracy of walks with eyes closed. Delays of 2 and 4 s between viewing the target and walking did not …

The development of a proff of principle superfluid Joule-Thomson refrigerator for cooling below 1 Kelvin
… of sub-Kelvin refrigerator, the superfluid Joule-Thomson refrigerator, has been developed and its performance has been experimentally verified. This refrigerator uses a liquid superfluid mixture of He and 4He as the working fluid and depends on the non-ideal-gas-like behavior of the 3He component …

Noncollective X-Ray Thomson Scattering Diagnostic Development Based On A Titanium Hybrid X-Pinch X-Ray Source
X-ray Thomson scattering (XRTS) is the combination of elastic Raleigh scattering and inelastic Compton scattering observed from high density systems using energetic probe energies at the keV x-ray level. Thermal x-ray probes have historically been created by delivering 1014 [-] 1016 W/cm2 to a …

Shear-Induced Vertical Mixing in the Wyville Thomson Basin: A Study of its Driving Mechanisms, Strength and Influence
Direct observations of turbulent kinetic energy dissipation rate are presented and analysed in this thesis, along with some theoretical studies to aid their interpretation. Vertical mixing in the study region is strongly coupled with the internal tide, generated by flow over the local topographic …
