We present an analysis of the mass distribution in the core of A 383 (z = 0.188), one of twelve X-ray luminous galaxy clusters at z ∼ 0.2 selected for a comprehensive and unbiased study of the mass distribution in massive galaxy clusters. Deep optical imaging performed by the Hubble Space Telescope (HST ) reveals a wide variety of gravitationally lensed features in the core of A 383, including ...

The intensity of the strong N v 1240 line relative to C iv 1549 or to He ii 1640 has been proposed as an indicator of the metallicity of quasi-stellar object (QSO) broad emission line regions, allowing abundance measurements in a large number of QSOs out to the highest redshifts. Previously, it had been shown that the (normally) much weaker lines N iii] 1750 and N iv] 1486 could be used in the ...

We report fungal pathogens of invertebrates (FPI) (Entomophthorales, Hypocreales, and Orbiliales) from roots an endemic Mexican pine, Pinus greggii Engelm. ex Parl., at four primary montane forests using next-generation sequencing. found twenty-nine OTUs 18 genera FPI associated to the P. greggii. New records for Mexico are: Beauveria felina (DC.) J.W.Carmich., Dactylella mammillata S.M. Dixon,...

Fischer provided a new type of binomial determinant for the number alternating sign matrices involving third root unity. In this paper we prove that her formula, when replacing unity by an indeterminate q, actually gives (q?1+2+q)-enumeration matrices. By evaluating generalisation are able to reprove conjecture Mills, Robbins and Rumsey stating Q-enumeration is product two polynomials in Q. Fur...

Using stimulated Raman adiabatic passage (SARP), it is possible, in principle, to transfer all the population in a rovibrational level of an isolated diatomic molecule to an excited rovibrational level. We use an overlapping sequence of pump (532 nm) and dump (683 nm) single-mode laser pulses of unequal fluence to prepare isolated H2 molecules in a molecular beam. In a first series of experimen...

The adaptation of the most strains of the fungus Lecanicillium muscarium ZARE & GAMS to moderate temperatures and humidity higher 80% as well as the sensitiveness of the spores to UVradiation explains, that the application regime mainly takes place under protected conditions in greenhouses. Laboratory trials with a very effective strain for the use as biological control agent (strain V24, secti...
