The inclusive single and double differential cross-sections for neutral and charged current processes with four-momentum transfer squared É ¾ between ½½¼ and ¿¼ ¼¼¼ Î ¾ and with Bjorken Ü between ¼¼¼¿¾ and ¼ are measured in · Ô collisions. The data were taken with the H1 detector at HERA between 1994 and 1997, and they correspond to an integrated luminosity(More)

The elastic electroproduction of mesons is studied at HERA with the H1 detector for a photon virtuality in the range ½ É ¾ ¼ Î ¾ and for a hadronic centre of mass energy in the range ¿¼ Ï ½½¼ GeV. The shape of the () mass distribution in the resonance region is measured as a function of É ¾. The full set of spin density matrix elements is determined, and(More)
BACKGROUND C-Fos was initially described as oncogene, but was associated with favourable prognosis in ovarian cancer (OvCa) patients. The molecular and functional aspects underlying this effect are still unknown. METHODS Using stable transfectants of SKOV3 and OVCAR8 cells, proliferation, migration, invasion and apoptotic potential of c-FOS-overexpressing(More)
A simple and fast computational model to describe the dynamics of tumour growth and metastasis formation is presented. The model is based on the calculation of successive generations of tumour cells and enables one to describe biologically important entities like tumour volume, time point of 1st metastatic growth or number of metastatic colonies at a given(More)
A detection of-rays from Mkn 421 at energies above 1 TeV is reported, based on observations made in December 1994-May 1995 with the rst two HEGRA Cherenkov telescopes. From the image analysis, 111 excess gamma candidates are obtained from the 26 h Telescope #1 (CT1) dataset (signiicance 4.0) and 218 from the 41 h Telescope #2 (CT2) dataset (signiicance 4.2)(More)
Photoproduction data collected with the H1 detector at HERA in 1994 are used to study the cross-sections for inclusive charged particle production and the structure of the photon. The diierential cross-sections d=dp 2 T ; for jj < 1 in the HERA laboratory frame, and d=d for p T > 2 GeV/c and p T > 3 GeV/c have been measured. Model calculations of these(More)

Internal jet structure in dijet production in deep-inelastic scattering is measured with the H1 detector at HERA. Jets with transverse energies E T,Breit > 5 GeV are selected in the Breit frame employing k ⊥ and cone jet algorithms. In the kinematic region of squared momentum transfers 10 < Q 2 120 GeV 2 and x-Bjorken values 2 · 10 −4 x Bj 8 · 10 −3 , jet(More)
A detection of TeV γ-rays from Mkn 501 is reported , based on observations made between March and August 1996 with the first HEGRA Cherenkov telescope (CT1). From the image analysis, 351 excess candidate γ-ray events are obtained from the 147 h dataset. The statistical significance of the excess is 5.2 σ. The average excess rate is 2.4 ± 0.5 h −1 above the(More)
