In order to explore the influence of cold-pressing and constant-volume sintering molding process on the friction and mechanical properties of porous polyimide (PI) materials, the effects of density, sintering temperature and holding time on the oil content, friction coefficient, tensile strength and impact strength of porous PI materials were studi
Understanding how initial radiation injury translates into long-term effects is an important problem in radiation biology.Here, we define a set of changes in the transcription profile that are associated with the long-term response weboost splitter to radiation exposure.The study was performed in vivo using zebrafish, an established radiobiological
Various speed scenarios such as high-speed travelling trains and connected drones over ultra-dense heterogeneous networks (HetNets) may result in a large number of handovers (HOs), which may cause further mobility challenges.Therefore, mobility robustness optimization (MRO) function has been proposed to contribute for detecting and correcting the m
The inter-cities mobility network is of great importance in understanding outbreaks, especially in Brazil, a continental-dimension country.We adopt the data from the Brazilian Ministry of Health read more and the terrestrial flow of people between cities from the Brazilian Institute of Geography and Statistics database in two scales: cities from Br
