Stereotypic movement disorders (SMD) such as head-banging, which are common among children with mental retardation or pervasive developmental disorders, may also occur in intellectually normal adults. We report a 27-year history of daily head-banging with self-injury in a 49-year-old man with normal cognition. The patient had no personal or family history(More)
The beauty production cross section for deep inelastic scattering events with at least one hard jet in the Breit frame together with a muon has been measured, for photon virtualities Q 2 > 2 GeV 2 , with the ZEUS detector at HERA using integrated luminosity of 72 pb −1. The total visible cross section is σ bb (ep → e jet µ X) = 40.9 ± 5.7 (stat.) +6.0 −4.4(More)
Differential inclusive jet cross sections in neutral current deep inelastic ep scattering have been measured with the ZEUS detector using an integrated luminosity of 38.7 pb −1. The jets have been identified using the k T cluster algorithm in the longitudinally invariant inclusive mode in the laboratory frame; they have been selected with jet transverse(More)

Next-to-leading-order QCD analyses of the ZEUS data on deep inelastic scattering together with fixed-target data have been performed, from which the gluon and quark densities of the proton and the value of the strong coupling constant, α s (M Z), were extracted. The study includes a full treatment of the experimental systematic uncertainties including(More)

Dijet angular distributions of photoproduction events in which a D * ± meson is produced in association with one of two energetic jets have been measured with the ZEUS detector at HERA, using an integrated luminosity of 120 pb −1. Differential cross sections as a function of the angle between the charm-jet and the proton-beam direction in the dijet rest(More)

First measurements of cross sections for isolated prompt photon production in deep inelastic ep scattering have been made using the ZEUS detector at the HERA electron-proton collider using an integrated luminosity of 121 pb −1. A signal for isolated photons in the transverse energy and rapidity ranges 5 < E γ T < 10 GeV and −0.7 < η γ < 0.9 was observed for(More)
INTRODUCTION ESWT refers to the use of Shock Waves in medical practice. It was used as an important tool in spasticity management of children with CP. The aim of our study was to evaluate the effect of a 3 session of ESWT on spastic upper and lower limbs muscles in children with CP. METHODS Sixty-three children (37 boys and 26 girls), mean age 99.57±53.74(More)

A search for narrow-width resonances that decay into electron+jet or neu-trino+jet has been performed with the ZEUS detector at HERA operating at center-of-mass energies of 300 and 318 GeV. An integrated e + p luminosity of 114.8 pb −1 and e − p luminosity of 16.7 pb −1 were used. No evidence for any resonance was found. Limits were derived on the Yukawa(More)
A search for pentaquarks decaying to Ξ − π − (Ξ − π +) and corresponding antiparticles has been performed with the ZEUS detector at HERA. The data sample consists of deep inelastic ep scattering events at centre-of-mass energies of 300 and 318 GeV, and corresponds to 121 pb −1 of integrated luminosity. A clear signal for Ξ 0 (1530) → Ξ − π + was observed.(More)
The dependence of dijet production on the virtuality of the exchanged photon, Q 2 , has been studied by measuring dijet cross sections in the range 0 < ∼ Q 2 < 2000 GeV 2 with the ZEUS detector at HERA using an integrated luminosity of 38.6 pb −1. Dijet cross sections were measured for jets with transverse energy E jet T > 7.5 and 6.5 GeV and(More)
