We study in a quantitative way CP-violating effects in neutrino oscillation experiments in the light of current and future data. Different scenarios with three and four neutrinos are worked out in detail including matter effects in long baseline experiments and it is shown that in some cases CP-violating effects could affect the analysis of a possible… (More)
Vector control constitutes an important component of integrated disease control campaigns. Source reduction is not an option for phlebotomine sand fly vectors of leishmaniasis, because larval breeding sites remain either unknown or inaccessible. Thus, all control efforts are directed against the adult sand flies, mostly attempting to limit their contact… (More)
Assuming three-neutrino mixing, we study the capabilities of very long baseline neutrino oscillation experiments to verify and test the MSW effect and to measure the lepton mixing angle θ 13. We suppose that intense neutrino and antineutrino beams will become available in so–called neutrino factories. We find that the most promising and statistically… (More)
We have searched for near-infrared extragalactic background light (EBL) in the data from the Near-InfraRed Spectrometer (NIRS) on the Infrared Telescope in Space (IRTS). After subtracting the contribution of faint stars and the zodiacal component based on modeling, a significant isotropic emission is obtained in the wavelength bands from 1.4 µm to 4.0 µm.… (More)
A new guanidine-thiourea organocatalyst has been developed and applied as bifunctional organocatalyst in the Michael addition reaction of diethyl malonate to trans-β-nitrostyrene. Extensive DFT calculations, including solvent effects and dispersion corrections, as well as ab initio calculations provide a plausible description of the reaction mechanism.
Simple unmodified N-proline-based di- and tripeptides in combination with sodium hydroxide additive catalyze the asymmetric Michael reaction of ketones with nitroolefins to furnish the corresponding gamma-nitroketones with up to 99% yield, 99:1 dr and 70% ee at room temperature and on water without any organic cosolvent.

Abstract Assuming three-neutrino mixing, we study the capabilities of very long baseline neutrino oscillation experiments to verify and test the MSW e!ect and to measure the lepton mixing angle.
