astro-ph9610007 | we report the observation by the _ compton gamma ray observatory _ of a spectacular flare of radio source pks1622@xmath0297 . a peak flux of @xmath1@xmath2s@xmath3 ( e @xmath4 100 mev ) was observed . the corresponding isotropic luminosity is 2.9 erg / s . we find that pks 1622@xmath0297 exhibits intra - day variabilit... | 271 |
0912.4897 | a model for charge transport in undoped , photo - excited semiconductor superlattices , which includes the dependence of the electron - hole recombination on the electric field and on the photo - excitation intensity through the field - dependent recombination coefficient , is proposed and analyzed . under dc voltage b... | 201 |
cond-mat0303335 | we have performed experiments of axial segregation in the oyama s drum . we have tested binary granular mixtures during very long times . the segregation patterns have been captured by a ccd camera and spatio - temporal graphs are created . we report the occurence of instabilities which can last several hours ! we stre... | 109 |
1411.6807 | during the last century , with the development of modern physics in such diverse fields as thermodynamics , statistical physics , and nuclear and particle physics , the basic principles of the evolution of stars have been successfully well understood . nowadays , a precise diagnostic of the stellar interiors is possibl... | 128 |
