The chemical abundances of our candidates (at [Fe/H] of -1.5 to -2.6 dex) vastly overlap with those of halo stars and our sample also contains one CEMP-s and a CH-star - the first detections of such objects in the bulge. ...

. Comment on J0405+3803 . Our image contains a feature of 25 mJy at 14 mas E-NE from the brightest component. It is not visible in the Caltech-Jodrell (CJ) survey image at 5 GHz (Xu et al. 1995) obtained about 6 years earlier. The 1.6 GHz CJ image (Polatidis et al. 1995) does show an extended feature close to the position in question, but somewhat displaced toward west. VLBApls home page . Last modified: 16 Oct 2000

... Recently, using this propagation rule for a function with special (discretely concave) values at two adjoint facets of the tetrahedron, Knutson, Tao and Woodward, established associativity of the Hives category, that is indeed an interesting bijection between two sets of special pairs of Young tableaux (we call them Standard pairs). ... As a consequence we obtain that the KTW bijection coincides with the bijection constructed by the authors for associativity of the array category. ...
