Collaborating to develop an online resource for parents
Background The development and evaluation of Online Parent Information and Support (OPIS) involved the creation of a web resource for parents who needed support for the home-based management of their child's chronic kidney disease (CKD)
A Possible Solution to the Tritium Endpoint Problem
Scalar or right-chiral interaction currents may be expected to produce a
neutrino coupled to the electron which is different from, and perhaps even
orthogonal to, that coupled to the electron by the standard model weak
interaction. We show that, using reasonable parameter values for such
additional interactions, it is possible to generate a spectrum which, if
analyzed in the manner commonly employed by experimental groups, produces a
negative neutrino mass-squared.Comment: LaTeX, 7 pages, 1 Postscript figure, submitted to Phys. Lett.
Spatio-temporal modelling of extreme storms
A flexible spatio-temporal model is implemented to analyse extreme
extra-tropical cyclones objectively identified over the Atlantic and Europe in
6-hourly re-analyses from 1979-2009. Spatial variation in the extremal
properties of the cyclones is captured using a 150 cell spatial regularisation,
latitude as a covariate, and spatial random effects. The North Atlantic
Oscillation (NAO) is also used as a covariate and is found to have a
significant effect on intensifying extremal storm behaviour, especially over
Northern Europe and the Iberian peninsula. Estimates of lower bounds on minimum
sea-level pressure are typically 10-50 hPa below the minimum values observed
for historical storms with largest differences occurring when the NAO index is
positive.Comment: Published in at http://dx.doi.org/10.1214/14-AOAS766 the Annals of
