The Editorial team is committed to generally accepted ethical principles of publication of scientific materials and ethical principles of СОРЕ, is scrupulous about its scientific reputation, and does its best to ensure high quality of scientific publications, without changing the author's concept or violating the copyright. A decision on any article publication is made based on the peer reviews without bias, and does not depend on the authors' citizenship, nationality, or any other personal data.Peer Review Policy For the journal, a double-blind peer review system is adopted. The only person who knows the authors' and reviewers' names is the editor. The reviewer is selected based on the subject matter of the manuscript in question; he/she may not have working relationship with the manuscript author(s), i.e. act as the author's academic advisor, work in the same subdivision or be part of the same research team with the author, etc. The reviewer's assessment of the manuscript shall be unbiased. In case of any conflict of interests, the reviewer shall notify the Chief Editor of such, and withdraw from the peer review. The same is applied if the reviewer is not properly qualified for the manuscript assessment – he/she shall request that the editor exclude him/her from the manuscript peer review process. The reviewer provides objective and substantiated assessment of the research work in question, based on the following criteria: originality, topicality of the research, relevance of the research methods selected, research results interpretation, and bibliography. Any personal criticism towards the author is not acceptable. The Editor-in-Chief, the Editorial Board and International Advisory Board members and external reviewers shall treat any manuscript as a confidential document, and shall not disclose any information related to any manuscript to any third parties or use any data contained in any manuscript in their own research works (or otherwise for their own benefit) prior to the manuscript official publication. Manuscript Evaluation A decision on any article publication is made by the Editorial Board based on results of internal and external peer reviews. The Editorial team reserves the right to reject any works that do not correspond to the journal subject matter, have not passed peer review, or have been already published elsewhere. The process of any manuscript evaluation by the reviewer and Editorial Board takes two months on average. As a result, the author is informed of one of the following decisions: the article will be published "as is"; the article needs refining, following which it will be re-evaluated by the Editorial Board (with possible engagement of external reviewers); the article is rejected. The author is also provided with basic comments and remarks, and the reasoning part of the peer review. The author may only submit the article for re-evaluation as thoroughly refined based on the editor's remarks, subject to the Editorial team prior consent to evaluate the refined version. The author whose work was rejected may submit any other of his/her manuscripts for evaluation. Editing principles During preparation for publication, any manuscript shall be edited, following which the author will receive the final version for the purpose of approval of all the changes made. In case of multiple authors, the text shall be sent to the responsible author for authorization to the e-mail specified in the article submission form. The responsible author shall ensure familiarization of all the authors with the final version. Should any author reveal any material errors or inaccuracies in the article during its evaluation or following its publication, he/she shall notify the Editorial team accordingly as soon as possible. Retraction Rules The purpose of retraction: the publication contains either plagiarism or a big portion of self-plagiarism; in cases of redundant publication (i.e. when authors present the same data in several publications); in case of copyright infringement (i.e. either one or more authors are not mentioned or the findings have been published without permission); failure to disclose a major competing interest likely to influence interpretations or recommendations; the findings are unreliable, either as a result of misconduct (e.g. data fabrication) or honest error (e.g. miscalculation or experimental error). Articles may be retracted by their author(s) or by the Editorial team based on their own expertise or received information from the third party. The Editorial team informs the author(s) about the retraction with justifying the reason. Retracted articles are identified on the journal website (on the table of contents of the issue and on the article page). The date and the reason of retraction is indicted on the article page. The Editorial team should inform about retracting material the Council on the Scientific Publications Ethics (Russian Association of Scientific Editors and Publishers), the National Electronic Library (NEL), and any bibliographic databases where the Journal is indexed. The retraction procedure is carried out without statute of limitations for articles. on the Main
