The conference participants will obtain Book of Abstracts at the registration desk. All accepted papers (delivered before April 25, 2020) will be published (in English only) in peer-reviewed Conference Proceedings. The organizers intend to publish the Conference Proceedings through AIP Publishing (American Institute of Physics). The AIP Conference Proceedings are indexed in leading databases, such as Conference Proceedings Citation Index (part of Web of Sciences), Scopus (Elsevier), Inspec etc. The online version of the Conference Proceedings will be published later, but surely in year 2020. Details for publishing in Conference Proceedings will be available in the second announcement.
