BACKGROUND Deletion and the reciprocal duplication in 16p11.2 were recently associated with autism and developmental delay. METHOD We indentified 27 deletions and 18 duplications of 16p11.2 were identified in 0.6% of all samples submitted for clinical array-CGH (comparative genomic hybridisation) analysis. Detailed molecular and phenotypic(More)
AIMS To compare the lineage specific distribution of MUC1 and MUC2 mucins in normal colorectal mucosa and adenocarcinoma and to identify pathological correlations. METHODS Paraffin wax sections from 51 colorectal cancers were examined for the expression of MUC1 and MUC2, non-O-acetyl sialic acid and the carbohydrate epitopes Lex, Ley, sialosyl-Lex,(More)
Expression of the core blood group structures sialosyl Tn (STn) and Tn is regarded as a colorectal cancer-specific change reflecting truncated synthesis of the oligosaccharide component of goblet cell mucin. The distribution of STn and Tn in normal and malignant epithelium has been studied in detail by a combination of mucin-, lectin-, and(More)
The jet energy scale (JES) and its systematic uncertainty are determined for jets measured with the ATLAS detector using proton–proton collision data with a centre-ofmass energy of √ s = 7 TeV corresponding to an integrated luminosity of 4.7 fb−1. Jets are reconstructed from energy deposits forming topological clusters of calorimeter cells using the anti-kt(More)
A search for scalar particles decaying via narrow resonances into two photons in the mass range 65-600 GeV is performed using 20.3  fb(-1) of √s 8 TeV pp collision data collected with the ATLAS detector at the Large Hadron Collider. The recently discovered Higgs boson is treated as a background. No significant evidence for an additional signal is observed.(More)
The production of a Z boson in association with a J/ψ meson in proton–proton collisions probes the production mechanisms of quarkonium and heavy flavour in association with vector bosons, and allows studies of multiple parton scattering. Using 20.3 fb−1 of data collected with the ATLAS experiment at the LHC in pp collisions at √ s = 8 TeV, the first(More)
This paper reports on a search for narrow resonances in diboson production in the qq̄ final state using pp collision data corresponding to an integrated luminosity of 20 fb−1 collected at √ s = 8 TeV with the ATLAS detector at the Large Hadron Collider. No significant excess of data events over the Standard Model expectation is observed. Upper limits at the(More)
A search is presented for dark matter pair production in association with a W or Z boson in pp collisions representing 20.3  fb(-1) of integrated luminosity at √s=8  TeV using data recorded with the ATLAS detector at the Large Hadron Collider. Events with a hadronic jet with the jet mass consistent with a W or Z boson, and with large missing transverse(More)
Two-particle correlations in relative azimuthal angle (Δø) and pseudorapidity (Δη) are measured in sqrt[s(NN)] = 5.02 TeV p+Pb collisions using the ATLAS detector at the LHC. The measurements are performed using approximately 1 μb(-1) of data as a function of transverse momentum (p(T)) and the transverse energy (ΣE(T)(Pb)) summed over 3.1 < η < 4.9 in the(More)
A measurement of spin correlation in tt[over ¯] production is presented using data collected with the ATLAS detector at the Large Hadron Collider in proton-proton collisions at a center-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 20.3  fb^{-1}. The correlation between the top and antitop quark spins is extracted from dilepton(More)
