We consider the geometric quantisation of Chern--Simons theory for closed genus-one surfaces and semisimple complex groups. First we introduce natural complexified analogue Hitchin connection in K\{a}hler quantisation, with polarisations coming from nonabelian Hodge hyper-K\{a}hler geometry moduli spaces flat connections, thereby complementing real-polarised approach Witten. Then Witten, identi...

Polarised quark distributions are extracted from semi-inclusive deep inelastic scattering data, which include the additional detection of a leading hadron to providestatisticaìàvour-tagging'. Results are combined from both proton and`neutron' targets to isolate the contributions to the nucleon spin of the individual quark avours, including the sea quarks. Spin asymmetries in the semi-inclusive ...

In this note the ILC’s capabilities for detecting WIMPs and measuring their properties are studied. The expected signal cross section is derived in a model-independent way from the observed relic density of Dark Matter. Signal events are detected by means of initial state radiation (ISR). The study is performed with a full simulation of the ILD detector. The results show that WIMPs are observab...

Juvenile rainbow trout (Oncorhynchus mykiss) were given ethambutol (900 mg kg-1 body mass per day) for 4 weeks to examine its effects on vision. Using multi-unit recording from the optic nerve, spectral sensitivity of the on-responses were significantly affected in two regions, 340-440 nm and 600-660 nm. Off-responses were statistically unaffected. Changes in sensitivity to polarised light were...

We study doubly polarised asymmetries of ¯ cc and ¯ bb mesons in hadro-and photo-production at low transverse momentum in non-relativistic QCD to high orders in the relative velocity of the pair, v. We give the complete set of expressions required for the asymmetries up to order v 9. The asymmetries in the production of η c,b states are a stable measure of the polarised gluon densities. The asy...

Short dangling bond wires (DB wires), fabricated on H-terminated Si(001) surfaces, show patterns of displacement that depend on their length. We have performed density function calculations, with and without spin-polarisation, designed to investigate the atomic and electronic structure of these wires. As expected, we find that even length wires are accurately modelled by non-spin polarised calc...

The role of competition in healthcare is much debated. Despite a wealth of international experience in relation to competition, evidence is mixed and contested and the debate about the potential role for competition is often polarised. This paper considers briefly some of the reasons for this, focusing on what is meant by “competition in healthcare” and why it is more valuable to think about th...
