A precise measurement of the inclusive deep-inelastic e + p scattering cross section is reported in the kinematic range 1.5 ≤ Q 2 ≤ 150 GeV 2 and 3 · 10 −5 ≤ x ≤ 0.2. The data were recorded with the H1 detector at HERA in 1996 and 1997, and correspond to an integrated luminosity of 20 pb −1. The double differential cross section, from which the proton(More)
A search for squarks in R-parity violating supersymmetry is performed in e + p collisions at HERA at a centre of mass energy of 300 GeV, using H1 data corresponding to an integrated luminosity of 37 pb −1. The direct production of single squarks of any generation in positron-quark fusion via a Yukawa coupling λ ′ is considered, taking into account R-parity(More)
We present an information extraction system for patient records which has been submitted to the ShARe/CLEF eHealth Evaluation Lab 2014 Task 2. The task was information extraction from clinical text in terms of a disease/disorder template filling process. The system uses a lexicalized parser to annotate grammatical relations between diseases, disorders, and(More)
A search for squarks in -parity violating supersymmetry is performed in collisions at HERA at a centre of mass energy of GeV, using H1 data corresponding to an integrated luminosity of pb . The direct production of single squarks of any generation in positron-quark fusion via a Yukawa coupling is considered, taking into account -parity violating and(More)
In this paper is presented an apparatus for measurement of thermophysical parameters and control of quality of equipments in high vacuum also in high and low temperature conditions. The equipment gives possibility to explore the measurement dynamics depending on level of temperature and vacuum, also tightness control of joints of materials.
AREAL (AdvancedResearchElectronAccelerator-Laboratory) is the laser driven RF gun based on 5MeV(Phase 1) electron linear accelerator project. The main goal of the vacuum system is to maintain a mean pressure of 1 nTorr, with beam. The vacuum system is entirely oil less and all the vacuum components are all metal type.
