In the background of all of Radojcic's scientific works were the doctrine of anthroposophy and geometry as its essential part. It led him to, at the time, most contemporary problems in mathematics and mathematical physics. His interest in Medieval art reveals a personality capable to unify by itself artistic and scientific worldview. His published works were digitized in 2008 at the Mathematical Institute of the Serbian Academy of Sciences and Arts and exhibited as a part of the virtual library of the National Center for Digitization. Some of his papers, both published and unpublished ones, are extremly actual and their republishing could be very important not only for scientific but also for general public as well展开更多

Until now, understanding these micro-processes is still a challenge despite rich astrophysical observation data have been obtained. Laboratory astrophysics, a new route to study the astrophysics, allows us to investigate them at similar extreme physical conditions in laboratory. Here we will review the recent progress of the collisionless shock experiments performed at SG-II laser facility in China. The evolution of the electrostatic shocks and Weibel-type/filamentation instabilities are observed. Inspired by the configurations of the counter-streaming plasma flows, we also carry out a novel plasma collider to generate energetic neutrons relevant to the astrophysical nuclear reactions.展开更多

The algorithm is tested using Greenhouse gases Observing SATellite (GOSAT) LIB data and validated using the Total Column Carbon Observing Network (TCCON) measurements. The retrieved XCO2 agrees well with TCCON measurements in a low bias of 0.15 ppmv and RMSE of 1.48 ppmv, and captured the seasonal vari- ation and increasing of XCO2 in Northern and Southern Hemisphere, respectively, as other measurements.展开更多
