As part of an ongoing project aimed at developing vaccine candidates against Cryptococcus neoformans the preparation of tri- and tetrasaccharide thioglycoside building blocks, to be used in construction of structurally defined part structures of C. neoformans GXM capsular polysaccharide, was investigated. Using a naphthalenylmethyl (NAP) ether as a temporary protecting group and trichloroacetim...

Laevens et al. recently discovered TriangulumII (TriII), a satellite of the Milky Way. Its Galactocentric distance is 36 kpc, and its luminosity is only  L 450 . Using Keck/DEIMOS, we measured the radial velocities of six member stars within 1 2 of the center of TriII, and we found a velocity dispersion of s = + 5.1 km s v 1.4 4.0 1. We also measured the metallicities of three stars and fou...

Two experiments examined the relations among adult aging, mind wandering, and executive-task performance, following from surprising laboratory findings that older adults report fewer task-unrelated thoughts (TUTs) than do younger adults (e.g., Giambra, 1989; Jackson & Balota, 2012). Because older adults may experience more ability- and performance-related worry during cognitive tasks in the lab...

In the title compound, (C(12)H(12)N(2))[Ta(2)F(10)O], the doubly protonated 5,6-dihydro-1,10-phenantroline-1,10-diium cation is located on a twofold rotation axis, whereas the isolated [Ta(2)OF(10)](2-) dianion has -1 symmetry. In the so far unknown dianion, the symmetry-related Ta(V) atoms are octa-hedrally coordinated by five F atoms and a bridging O atom, the latter being located on an inver...
