The conference participants will obtain Book of Abstracts at the registration desk. All accepted papers (delivered before April 30, 2019) 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 Conference Proceedings will be sent to the participants later, but surely in year 2019. Details for publishing will be available in the second announcement.
