Preparing manuscript

Each manuscript must be set in accordance with the norms established by the Editorial Office. Special importance is attached to the following directions:

1. The title of the paper should be as short as possible.
2. The authors of the paper should give full names (not only initials) and surnames, affiliations, addresses for correspondence, and e-mails of all authors. The corresponding author email should be pointed out. Please also provide the ORCID number (if exist).
3. The authors should enclose an abstract (summary) of the paper. The volume of the abstract should not exceed 150 words (1000 signs with spaces). The Abstract should be informative and briefly inform about motivation, problem statement, methodology, and results.
4. Keywords should be given.
5. It is also desirable to include a list of notation used in the paper.
6. The text should be preceded by a brief introduction.
7. Only such formulae should be numbered to which the author refers throughout the paper, and also the resulting formulae.
8. All the notation should be written very distinctly. Special care must be taken to write small and capital letters as precisely as possible (this especially applies to the designations of the letters i and O, b and P, s and S, z and Z, as well as zero 0 and o and O).
9. References in the text of the paper should be given in Arabic numerals in square brackets.
10. The reference list could be arranged in alphabetical order or in order of appearance of citations in text.
11. At the end of manuscript should be included (in the order given here): Acknowledgements/ Funding Acknowledgement (if relevant), a Declaration of Conflicting Interests, and References.
12. A Declaration of Conflicting Interests should be included under the heading 'Declaration of Conflicting Interest'. If no conflict exists, authors should include information 'The Author(s) declare(s) that there are no known competing financial interests or personal relationships that could influence the work reported in this paper’.
