hep-th0210296 | we study topological d - branes of type b in @xmath0 landau - ginzburg models , focusing on the case where all vacua have a mass gap . in general , tree - level topological string theory in the presence of topological d - branes is described mathematically in terms of a triangulated category . for example , it has been... | 216 |
astro-ph0306477 | standard solar models predict a solar luminosity that gradually increased by about 30% over the past 4.5 billion years . under the faint sun , earth should have been frozen solid for most of its existence . yet , running water is observed to have been present since very early in earth s history . this enigma is known a... | 187 |
cond-mat0308430 | we provide a quantitative determination of the crystallization onset for two electrons in a parabolic two - dimensional confinement . this system is shown to be well described by a roto - vibrational model , wigner crystallization occurring when the rotational motion gets decoupled from the vibrational one . the wigner... | 116 |
0802.1349 | we present results from neutral hydrogen ( hi ) observations of the tip of the magellanic stream ( ms ) , obtained with the arecibo telescope as a part of the on - going survey by the consortium for galactic studies with the arecibo l - band feed array . we find four large - scale , coherent hi streams , extending cont... | 295 |
1101.3120 | mass models for a sample of 18 late - type dwarf and low surface brightness galaxies show that in almost all cases the contribution of the stellar disks to the rotation curves can be scaled to explain most of the observed rotation curves out to two or three disk scale lengths . the concept of a maximum disk , therefore... | 217 |
