astro-ph0205208 | we present the _ xmm - newton _ observations of x - ray afterglows of the @xmath0-ray bursts grb 011211 and grb 001025 . for grb 011211 _ xmm _ detected fading x - ray object with an average flux in 0.2 - 10 kev declining from @xmath1 erg @xmath2 s@xmath3 during the first 5 ks of 27-ks observation to @xmath4 erg @xmath... | 197 |
1306.4105 | transport measurements were performed on the organic layered compound 3 under hydrostatic pressure . the carrier types , densities and mobilities are determined from the magneto - conductance of 3 . while evidence of high - mobility massless dirac carriers has already been given , we report here , their coexistence wit... | 109 |
1006.4566 | we study a two - point self - avoidance energy @xmath0 which is defined for all rectifiable curves in @xmath1 as the double integral along the curve of @xmath2 . here @xmath3 stands for the radius of the ( smallest ) circle that is tangent to the curve at one point and passes through another point on the curve , with o... | 246 |
0808.2187 | we construct effective 2- and 3-body hamiltonians for the p - shell by performing @xmath0 _ ab initio _ no - core shell model ( ncsm ) calculations for a=6 and 7 nuclei and explicitly projecting the many - body hamiltonians onto the @xmath1 space . we then separate these effective hamiltonians into 0- , 1- and 2-body c... | 107 |
1609.00814 | for sequences of random backward nested subspaces as occur , say , in dimension reduction for manifold or stratified space valued data , asymptotic results are derived . in fact , we formulate our results more generally for backward nested families of descriptors ( bnfd ) . under rather general conditions , asymptotic ... | 272 |
