A physical property model of the Chalk of Southern England

This report describes the rationale and procedure for the construction of a new high-resolution stratigraphical and physical property model of the Chalk Group of southern England. The model integrates bedrock mapping data for the Chalk, with structural data and interpretations of formational and sub-formational (marker-bed) stratigraphy in boreholes (predominantly from geophysical logs and cored boreholes) and outcrops. A range of simple facies data (e.g. hard chalk, hardground, marl, marly chalk) are coded for the boreholes and outcrops using WellCadTM software, interpreted directly from geophysical logs, core logs, borehole video logs, or outcrop logs. The results of this work are modelled in SKUA-GOCAD 2013.2 software, using statistical algorithms to project the likely distribution of physical property data

UK Stratigraphical Framework Series : Lower Cretaceous (Aptian-Albian) of Southern and Eastern England, and the Southern North Sea

This report forms part of the UK Stratigraphical Framework Series (UKSFS) and provides an overview of the stratigraphy of the Aptian-Albian (Lower Cretaceous) of southern and eastern England (and adjacent offshore areas). This interval includes the Lower Greensand and the Selborne Groups, the latter comprising the Gault and Upper Greensand Formations and coeval strata of the East Midlands Shelf. This interval forms a coherent body of transgressive marine siliciclastic deposits between the terrestrial to marginal-marine Wealden Group and the carbonates of the Chalk Group. The study adopted a surface to subsurface approach and makes extensive use of borehole geophysical log data. Stratigraphical picks based on geophysical log correlations were used to construct thickness maps. These maps were used in conjunction with borehole correlation panels to understand regional trends in thickness and lithology and how these evolved during Aptian-Albian marine transgression

UK Stratigraphical Framework Series : the Ancholme Group of the East Midlands shelf

This report forms part of the UK Stratigraphical Framework Series (UKSFS) and provides an overview of the stratigraphy of the Ancholme Group (combined Kellaways Formation, Oxford Clay Formation, West Walton Formation, Ampthill Clay Formation, Kimmeridge Clay Formation) of the East Midlands Shelf. The work is based on interpretation of borehole geophysical logs and published records of cored boreholes. The emphasis of the report is on establishing criteria that allow the confident subdivision of the Ancholme Group (a predominately marine mudrock succession) into its component parts

UK Stratigraphical Framework Series : Oxford Clay Formation

This report forms part of the UK Stratigraphical Framework Series (UKSFS) and provides an overview of the stratigraphy of the Oxford Clay of southern and eastern England. The work covers both outcrop and subcrop areas and is primarily based on new interpretations of borehole geophysical log and core sample data with reference to published materials and outcrop sections as required. The emphasis of the report is on regional structure, thickness and facies trends in the Oxford Clay Formation. It should provide a framework for site-specific geological investigations that require understanding of the Oxford Clay Formation

Probing Bogoliubov Quasiparticles in Superfluid 3He with a ‘Vibrating-Wire Like’ MEMS Device

International audienceWe have measured the interaction between superfluid 3 He-B and a micro-machined goalpost-shaped device at temperatures below 0.2 T c. The measured damping follows well the theory developed for vibrating wires, in which the An-dreev reflection of quasiparticles in the flow field around the moving structure leads to a nonlinear frictional force. At low velocities the damping force is proportional to velocity while it tends to saturate for larger excitations. Above a velocity of 2.6 mms −1 the damping abruptly increases, which is interpreted in terms of Cooper-pair breaking. Interestingly, this critical velocity is significantly lower than reported with other mechanical probes immersed in superfluid 3 He. Furthermore , we report on a nonlinear resonance shape for large motion amplitudes that we interpret as an inertial effect due to quasiparticle friction, but other mechanisms could possibly be invoked as well.

Feasibility randomised controlled trial of a guided workbook intervention to support work-related goals among cancer survivors in the UK

Objectives: Employment following illness is associated with better physical and psychological functioning. This study aimed to assess the feasibility and acceptability of a theoretically led workbook intervention designed to support patients with cancer returning to work. Design: Parallel-group randomised controlled trial with embedded qualitative interviews. Setting: Oncology clinics within four English National Health Service Trusts. Participants: Patients who had received a diagnosis of breast, gynaecological, prostate or colorectal cancer and who had been receiving treatment for a minimum of two weeks. Intervention: A self-guided WorkPlan workbook designed to support patients with cancer to return to work with fortnightly telephone support calls to discuss progress. The control group received treatment as usual and was offered the workbook at the end of their 12-month follow-up. Outcome measures: We assessed aspects of feasibility including eligibility, recruitment, data collection, attrition, feasibility of the methodology, acceptability of the intervention and potential to calculate cost-effectiveness. Results: The recruitment rate of eligible patients was 44%; 68 participants consented and 58 (85%) completed baseline measures. Randomisation procedures were acceptable, data collection methods (including cost-effectiveness data) were feasible and the intervention was acceptable to participants. Retention rates at 6-month and 12-month follow-up were 72% and 69%, respectively. At 6-month follow-up, 30% of the usual care group had returned to full-time or part-time work (including phased return to work) compared with 43% of the intervention group. At 12 months, the percentages were 47% (usual care) and 68% (intervention). Conclusions: The findings confirm the feasibility of a definitive trial, although further consideration needs to be given to increasing the participation rates among men and black and ethnic minority patients diagnosed with cancer

Polaron formation for a non-local electron-phonon coupling: A variational wave-function study

We introduce a variational wave-function to study the polaron formation when the electronic transfer integral depends on the relative displacement between nearest-neighbor sites giving rise to a non-local electron-phonon coupling with optical phonon modes. We analyze the ground state properties such as the energy, the electron-lattice correlation function, the phonon number and the spectral weight. Variational results are found in good agreement with analytic weak-coupling perturbative calculations and exact numerical diagonalization of small clusters. We determine the polaronic phase diagram and we find that the tendency towards strong localization is hindered from the pathological sign change of the effective next-nearest-neighbor hopping.Comment: 11 page
