Based on the photometric survey of the inner region of the Centaurus cluster (Jerjen & Dressler 1997a) we measured redshifts for a deep, surface brightness limited sample of galaxies using the MEFOS multifibre spectrograph at the ESO 3.6m telescope. With the new data set radial velocities for 120 centrally located cluster members become available which is equivalent to 78% of all known cluster ...

Having started with the general formulation of the quantum theory of the real scalar field (QFT) in the general Riemannian space–time V1,3 , the general–covariant quasinonrelativistic quantum mechanics of a point-like spinless particle in V1,3 is constructed. To this end, for any normal geodesic 1+3–foliation of V1,3 , a space Φ − of asymptotic in c −1 solutions of the field equation is specifi...

The vacuum energies corresponding to massive Dirac fields with the boundary conditions of the MIT bag model are obtained. The calculations are done with the fields occupying the regions inside and outside the bag, separately. The renormalization procedure for each of the situations is studied in detail, in particular the differences occurring with respect to the case when the field extends over...

This paper proposes a mechanism for learning pattern correspondences between two languages from a corpus of translated sentence pairs. The proposed mechanism uses analogical reasoning between two translations. Given a pair of translations, the similar parts of the sentences in the source language must correspond the similar parts of the sentences in the target language. Similarly, the different...

The optical counterpart of the Gamma–Ray Burst GRB 970228, discovered by Groot et al. (1997a), is also detected in the B and R frames obtained ∼4 hours earlier at the Bologna Observatory. Our observations indicate a very likely rise of the optical emission within these 4 hours. The R luminosity of the transient at maximum was about 15 times that of an underlying extended object. Follow–up data ...
