The recently constructed two dimensional Sen connection is applied in the problem of quasilocal energy-momentum in general relativity. First it is shown that, because of one of the two 2 dimensional Sen–Witten identities, Penrose’s quasi-local charge integral can be expressed as a Nester–Witten integral. Then, to find the appropriate spinor propagation laws to the Nester– Witten integral, all t...
Interactions between normal, protease-sensitive prion protein (PrP-sen or PrP(C)) and its protease-resistant isoform (PrP-res or PrP(Sc)) are critical in transmissible spongiform encephalopathy (TSE) diseases. To investigate the propagation of PrP-res between cells we tested whether PrP-res in scrapie brain microsomes can induce the conversion of PrP-sen to PrP-res if the PrP-sen is bound to un...
AIM To assess academic attainment and special educational needs (SEN) in extremely preterm children in middle childhood. METHODS Of 307 extremely preterm (< or =25 weeks) survivors born in the UK and Ireland in 1995, 219 (71%) were re-assessed at 11 years of age and compared to 153 classmates born at term, using standardised tests of cognitive ability and academic attainment and teacher repor...
