Line identification and lifetime measurements in the XUV and soft X-ray regions

A summary of the data acquired concerning line identification and lifetime measurements in the xuv and soft X-ray regions for a variety of both resonance transitions and forbidden transitions in ions of astrophysical interest is provided. Particular attention is called to a few papers which appeared in the Astrophysical Journal. These are of special relevance to specific astrophysical data needs. The many experiments completed in areas related to but somewhat outside the confines of the project title are mentioned

Skyrmions induced by dissipationless drag in U(1)xU(1) superconductors

Rather generically, multicomponent superconductors and superfluids have intercomponent current-current interaction. We show that in superconductors with substantially strong intercomponent drag interaction, the topological defects which form in external field are characterized by a skyrmionic topological charge. We then demonstrate that they can be distinguished from ordinary vortex matter by a very characteristic magnetization process due to the dipolar nature of inter-skyrmion forces. The results provide an experimental signature to confirm or rule out the formation $p$-wave state with reduced spin stiffness in $p$-wave superconductors.Comment: Replaced with a version in print in Physical Review B; Improved and extended as compared to the first version; 13 pages; 12 figure

Arguments en faveur d'une modification du génome (introgression) du parasite humain Schistosoma haematobium par des gènes de S. bovis, au Niger

La caractérisation de schistosomes par la morphologie des oeufs intra-utérins des vers femelles et l'analyse des phénotypes des parasites observés pour la phosphatase acide après séparation électrophorétique suggère la présence de gènes de #S. bovis, parasite du bétail domestique, chez les schistosomoses issus de l'homme dans la région est du Niger et présumés appartenir à #S. haematobium. Cette introgression naturelle pourrait également implique #S. curassoni$, un autre schistosome du bétail sympatrique des 2 autres espèces dans cette région. (Résumé d'auteur

Effect of dislocations on charge carrier mobility-lifetime product in synthetic single crystal diamond

The authors report correlations between variations in charge transport of electrons and holes in synthetic single crystal diamond and the presence of nitrogen impurities and dislocations. The spatial distribution of these defects was imaged using their characteristic luminescence emission and compared with maps of carrier drift length measured by ion beam induced charge imaging. The images indicate a reduction of electron and hole mobility-lifetime product due to nitrogen impurities and dislocations. Very good charge transport is achieved in selected regions where the dislocation density is minimal
