We study the perspectives of measuring the phenomenon of vacuum birefringence predicted by quantum electrodynamics using an x-ray free-electron laser (XFEL) alone.We devise an experimental scheme allowing two consecutive XFEL pulses to collide under a finite angle, and GIFT-SET thus act as both pump and probe field for the effect.The signature of v
The purpose of this article is to analyze the possibility and feasibility of using forms and methods of scientific and technical support to increase the efficiency of monitoring the properties and states of load-bearing structures.The task is to substantiate and develop an algorithm for assessing and predicting the states of load-bearing structures
The analysis of the secondary texts obtained as a result of a linguistic experiment has allowed the author to create a degree classification for the emergence of metalinguistic consciousness and to compare them to personalization and depersonalization tendencies.The classification, as well as various metaindicators, linguistic and extralinguistic f
Abstract Background Prophylaxis for high-risk populations, such as forest workers, could be one component for malaria elimination in the Greater Mekong Sub-region.A study was conducted to assess the malaria incidence in forest rangers and the feasibility of malaria prophylaxis for rangers sleeping in forest camps.Methods Forest rangers deployed in
