SimHealth: Estimating Small Area Populations Using Deterministic Spatial Microsimulation in Leeds and Bradford.

The increasing prevalence of obesity and type 2 diabetes in recent decades is often cited as a serious public health concern, lowering life expectancy and costing the National Health Service (NHS) billions of pounds each year. However, measuring diabetes prevalence proves challenging; the best estimates are based on the annual Health Survey for England (HSE) and little is currently available at the small area level. Simulation models are increasingly used in health research to predict future prevalence, cost of treatment, provision of care and the possible outcomes of policy intervention. Previous research shows the relevance of this technique in modelling the outcomes of changes in taxation and child benefit policy, or analysing health inequalities. This paper introduces SimHealth, a small-area diabetes prevalence model for Leeds and Bradford, West Yorkshire created as part of a generic model framework. The process of configuring an optimal spatial microsimulation model, building on earlier research, is detailed with the aim of improving and extending existing simulation models

Measurement of the cross section for isolated-photon plus jet production in pp collisions at √s=13 TeV using the ATLAS detector

The dynamics of isolated-photon production in association with a jet in proton–proton collisions at a centre-of-mass energy of 13 TeV are studied with the ATLAS detector at the LHC using a dataset with an integrated luminosity of 3.2 fb−1. Photons are required to have transverse energies above 125 GeV. Jets are identified using the anti- algorithm with radius parameter and required to have transverse momenta above 100 GeV. Measurements of isolated-photon plus jet cross sections are presented as functions of the leading-photon transverse energy, the leading-jet transverse momentum, the azimuthal angular separation between the photon and the jet, the photon–jet invariant mass and the scattering angle in the photon–jet centre-of-mass system. Tree-level plus parton-shower predictions from Sherpa and Pythia as well as next-to-leading-order QCD predictions from Jetphox and Sherpa are compared to the measurements

Measurement of W± and Z-boson production cross sections in pp collisions at √s=13 TeV with the ATLAS detector

B, All figures including auxiliary figures are available at https://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/PAPERS/STDM-2015-03/International audienceMeasurements of the $W^{\pm} \rightarrow \ell^{\pm} \nu$ and $Z \rightarrow \ell^+ \ell^-$ production cross sections (where $\ell^{\pm}=e^{\pm},\mu^{\pm}$) in proton-proton collisions at $\sqrt{s}=13$ TeV are presented using data recorded by the ATLAS experiment at the Large Hadron Collider, corresponding to a total integrated luminosity of 81 pb$^{-1}$. The total inclusive $W^{\pm}$-boson production cross sections times the single-lepton-flavour branching ratios are $\sigma_{W^+}^{tot}= 11.78 \pm 0.02 (stat) \pm 0.32 (sys) \pm 0.59 (lumi)$ nb and $\sigma_{W^-}^{tot} = 8.75 \pm 0.02 (stat) \pm 0.24 (sys) \pm 0.44 (lumi)$ nb for $W^+$ and $W^-$, respectively. The total inclusive $Z$-boson production cross section times leptonic branching ratio, within the invariant mass window $66 < m_{\ell\ell} < 116$ GeV, is $\sigma_{Z}^{tot} = 1.97 \pm 0.01 (stat) \pm 0.04 (sys) \pm 0.10 (lumi)$ nb. The $W^+$, $W^-$, and $Z$-boson production cross sections and cross-section ratios within a fiducial region defined by the detector acceptance are also measured. The cross-section ratios benefit from significant cancellation of experimental uncertainties, resulting in $\sigma_{W^+}^{fid}/\sigma_{W^-}^{fid} = 1.295 \pm 0.003 (stat) \pm 0.010 (sys)$ and $\sigma_{W^{\pm}}^{fid}/\sigma_{Z}^{fid} = 10.31 \pm 0.04 (stat) \pm 0.20 (sys)$. Theoretical predictions, based on calculations accurate to next-to-next-to-leading order for quantum chromodynamics and next-to-leading order for electroweak processes and which employ different parton distribution function sets, are compared to these measurements

Some developments in S.E.M. instrumentation

Work at the University of Sussex involving instrumental developments in scanning electron microscopy is reviewed. The apparatus developed includes a versatile channel plate detector and a liquid helium cooled stage. Some results obtained using this equipment are described. A new technique for obtaining crystallographic information in conjunction with scanning microscopy is described, and shown to have several advantages over previous techniques. The detection sensitivity of X-ray microprobe analysis for very thin layers has been explored and is found to be about 10-3 monolayers using wave-length dispersive detection and 10-1 monolayers using an energy-dispersive detection system commercially available for use with a scanning microscope.On rappelle les travaux effectués récemment à l'Université de Sussex sur les développements instrumentaux en microscopie électronique à balayage. Les appareils mis au point comportent un détecteur universel du type « channel plate » et une platine refroidie à l'hélium liquide. On décrit une nouvelle technique qui fournit en conjonction avec la microscopie à balayage des informations cristallographiques, et on montre qu'elle présente plusieurs avantages sur les techniques antérieures. On a étudié la sensibilité de détection en microanalyse par émission X sur des couches très minces, et on l'a trouvé égale à environ 10-3 monocouche par spectrométrie dispersive et à 16-1 monocouche par spectrométrie non dispersive avec un détecteur commercial
