Cosmology without time: What to do with a possible signature change from quantum gravitational origin?

open access: yes, 2016
Within some approaches to loop quantum cosmology, the existence of an Euclidean phase at high density has been suggested. In this article, we try to explain clearly what are the observable consequences of this possible disappearance of time. Depending on

Special Grain Boundaries in Ultrafine-Grained Tungsten

open access: yesNanoscale Research Letters, 2016
Field ion microscopy and computer simulation were used for the study of an atomic structure high-angle grain boundary in hard-drawn ultrafine-grained tungsten wire. These boundaries with special misorientations are beyond the scope of the coincident site lattice model.
