hep-th0002049 | the finite temperature casimir free energy is calculated for a dielectric ball of radius @xmath0 embedded in an infinite medium . the condition @xmath1 is assumed for the inside / outside regions . both the green function method and the mode summation method are considered , and found to be equivalent . for a dilute me... | 113 |
1410.3510 | we analyze a sample of 16 absorption systems intrinsic to long duration grb host galaxies at @xmath0 for which the metallicities are known . we compare the relation between the metallicity and cold gas velocity width for this sample to that of the qso - dlas , and find complete agreement . we then compare the redshift ... | 290 |
cs0303025 | we present a fully automatic method for music classification , based only on compression of strings that represent the music pieces . the method uses no background knowledge about music whatsoever : it is completely general and can , without change , be used in different areas like linguistic classification and genomic... | 101 |
1406.4559 | we perform classical molecular dynamics simulations to investigate the mechanical compression effect on the thermal conductivity of the single - walled carbon nanotube ( swcnt ) forest , in which swcnts are closely aligned and parallel with each other . we find that the thermal conductivity can be linearly enhanced by ... | 177 |
1504.05708 | in this paper we present the solver duquad specialized for solving general convex quadratic problems arising in many engineering applications . when it is difficult to project on the primal feasible set , we use the ( augmented ) lagrangian relaxation to handle the complicated constraints and then , we apply dual first... | 218 |
