%0 Journal Article %T Overcoming Fragility %A William Horowitz %J Physics %D 2006 %I arXiv %R 10.1016/j.nuclphysa.2006.11.112 %X We examine the sensitivity and surface bias of convolved DGLV radiative and elastic loss in a realistic geometry including Bjorken expansion. We find that this more faithful treatment of the medium density is not a priori reproducible via fixed length approximations, and neither the fragility nor the surface emission of BDMPS-based models is seen. %U http://arxiv.org/abs/nucl-th/0610024v1
