ABSTRACT We derive the local stellar formation history from Gaia-defined 40 pc white dwarf sample. This is currently largest volume-complete sample of dwarfs for which spectroscopy available, allowing classification chemical abundances at photosphere, and subsequently accurate determination atmospheric parameters. create a population synthesis model show that uniform last ≈10.5 Gyr provides sat...

The LHCb experiment at the LHC will upgrade its detector to take data at luminosities of above 1033 cm−2s−1 from 2018 onwards. The fully upgraded detector will use a new front-end electronics to readout collision events at 40MHz. A new fully software based trigger will be implemented and will increase the trigger efficiencies, specially in the hadronic decay channels. The silicon vertex detecto...

Basilar bifurcation aneurysms are lately treated frequently with endovascular technique. Microsurgical clipping occlusion technique has, however, still its solid position because of its completeness. This standard technique is required often due to unfeasibility and/or incompleteness at the time of application of the endovascular technique for aneurysms of this location. The authors suggest fol...

This paper describes the purification of polysomal RNA from SV40-lytically infected CV1 (monkey) cells and separation of the two distinct classes of SV40-specific mRNA sedimenting at 16 S and 19 S. These classes have been hybridized with the whole SV40 DNA genome as well as with the SV40 Hind fragments. The results have permitted the mapping of SV40-specific late 16 S mRNA from approximately 0....
