Manuscripts must be submitted online. The Corresponding Author must include all the eligible co-authors in the Author List (refer to Qualification for Authorship).

We consider for publication the manuscripts which have not been published before (except in the form of an abstract or as part of a published lecture or academic thesis or as an electronic preprint); are not being considered for publication elsewhere. The Corresponding Author should receive an approval for publication from all of the co-authors and all of the concerned parties before the submission.

To submit manuscripts the Corresponding Authors should register their personal account on and fulfil the following steps:

  • Get acquainted with the Guidelines for Authors and Manual for Authors.
  • Download MS Word Doc or LaTeX templates and prepare the manuscript in accordance with the Manuscript Style Guide.
  • Log in the personal account, proceed to the Submit Paper page and fulfil all the steps of the online submission procedure.

To feel more comfortable when working with Authors Webinterface, please look through the Manual for Authors before you start. The manual provides stepwise guidance through the paper submission process.

Manuscript Preparation

The text of a manuscript should be written in good English, including the text in tables and figures. Authors can submit papers in Doc or LaTeX format along with the corresponding PDF file. The manuscripts prepared in LaTeX must be collated into one ZIP folder (include all source files and images to allow the Editors recompile the submitted PDF).

The example of the required text formatting is provided in the Manuscript Preparation Template, which is available in MS Word Doc and LaTeX formats.

Paper structure

Manuscripts should be structured as follows:

Title The title should adequately describe the content of the paper. Abbreviations should be avoided wherever possible.

Author names and affiliations Indicate the name(s) of each Author and check the spelling of all names. Provide the Authors' affiliations as follows: Department, Institution, City, Country. Provide the email address of each Author. Please mark the Corresponding Author with an asterisk.

Keywords Provide a list of keywords covered in your paper. These keywords will also be used by the publisher to produce a keyword index.

Abstract The abstract should briefly state the purpose of the research, briefly describe the basic methodology, and report the main results and conclusions. References should be avoided. The abstract should be 150-300 words in length and comprise a single paragraph.

Subject classification numbers Physics and Astronomy Classification System (PACS) codes, Mathematics Subject Classification (MSC2010) or other classification scheme numbers should come immediately after the abstract. Classification codes help Editors choose suitable referees.

Introduction In the Introduction it is necessary to state the objectives of the work, reflect the relevance of the results and give references to relevant literature, avoiding a detailed literature survey or a summary of the results.

Theory In the Theory section, it is necessary to give a theoretical and/or methodical basis that is required for obtaining results of the paper.

Materials and Methods The Materials and Methods section is intended to give a detailed account of the procedure that was followed in completing the experiment(s) discussed in the manuscript. In this section, the Authors should describe the materials used, explain how the materials were prepared for the study, describe the research method(s), explain how the measurements were made and the calculations were performed, and state which statistical tests and software were employed to analyse the data.

Results Provide a concise and precise description of the theoretical/experimental results, their interpretation. All of Author’s results should have the justification and proofs. The results and proofs should be distinct and clear.

Discussion Provide an estimation of the results and outline possible future directions of the research. The Discussion section should explore the significance of the results of the work, not repeat them.

Conclusions Provide the main conclusions that can be drawn from the research results in brief.

Conflict of Interest Authors must identify and declare any personal circumstances or interest that may be perceived as inappropriately influencing the representation or interpretation of reported research results. If there is no conflict of interest, please state “The author(s) declare(s) that there is no conflict of interest.”

Any role of the funding sponsors in the design of the study; in the collection, analyses or interpretation of data; in the writing of the manuscript, or in the decision to publish the results must be declared in this section.

Acknowledgements All sources of funding of the study should be disclosed. Indicate clearly the grants received in support of your research and funds for the publication costs coverage. Authors may acknowledge assistance or encouragement from the colleagues who do not qualify for authorship (refer to Qualification for Authorship).

References The journal has its own reference style. The references are listed in the numerical order in which they are cited in the text.

Reference Style Guide

The reference indicates bibliographical records about the cited document necessary and sufficient for its identification and search. Along with information such as author(s), date of publication, title and page numbers, references may also include unique identifiers such as DOI depending on the type of work being referred to.

For the bibliographic records by three or fewer authors, the names of all the authors should be given. For example, [three authors: A.N. Author, P.L. Storyteller, A.N. Writer.] If a bibliographic record has four or more authors, only the name of the first author and “et al.” after it should be given. For example, [five authors: A.N. Author et al.]

The reference list comes at the end of a manuscript. References are cited in the text by the numbers in square brackets, as [1], [3–8], [2, 4, 7, 10]. The references are to be numbered in the order in which they are referred to in the text. All sources in the References section should be formatted according to the Journal reference style:

All of the tables should be numbered and have headings. In the text, they should be referred to as Table 1, Table 2, etc. Do not break tables. Tables should be placed in the main text and be centred unless they occupy the full width of the page (within margins). Avoid complex formatting, use the basic Table format in Word or Excel instead. All of the data should be easy to read.


All of the figures should be numbered and have captions. They should be referred to in the text as Fig. 1, Fig. 2, etc. Generally, only original drawings or photographic reproductions of good quality are acceptable. For best quality, the pictures should have a resolution of 300 dpi (dots per inch). Common formats are accepted. All figures must be placed in the text as close as possible to the point where they are first mentioned.

Equations and mathematics

Equations should remain editable and not appear in a picture format. Type the mathematical equations in the simplest way possible. Make sure that your Equation Editor or MathType fonts, including sizes, are set up to match the text of your document. Equations that are referred to in the text should be numbered sequentially throughout the text. Equations may be referred to in the text as Eq.(1). The use of Word’s built-in Equation Editor or the full MathType product is allowed.

Scientific names

A scientific name should be written in full at the first use of the species name. The genus should be abbreviated in subsequent usages in the text. Genus and species names are given in italics. Authors are encouraged to indicate full authorships of species (author and date) and to cite the original descriptions.

Qualification for Authorship

The people who have made a significant contribution to the work through the development of the design and concept of the research, data processing and analysis, writing or revising the manuscript and who can be considered accountable for all aspects of the work should be identified as Authors. Acknowledge contributors who do not qualify for authorship separately (attraction of funding or general administrative support; writing assistance, technical editing, language editing, proofreading, etc.)

Quality Control

After an Author submitted a manuscript, the Editors screen the manuscript for suitability to the basic requirements of the journal and decide whether to assign Reviewers to it or decline the manuscript. Having been checked by the Editors, manuscripts undergo a peer review. The peer review process takes 3-5 weeks. Upon completion of the peer review, all the Reviewers send their detailed Review Reports with comments and recommendations on the manuscript to the Editors. Having checked the reports, Editors make the final decision to accept the manuscript for publication or to reject it. The detailed description of the editorial process is available on the Peer Review & Quality Control page. All the Editors follow the COPE’s Code of Conduct and Best Practice Guidelines for Journal Editors. All the Reviewers follow the COPE’s Ethical Guidelines for Peer Reviewers as outlined by the Committee on Publication Ethics (COPE).

Appeal against Editors' Decisions

Authors have the right to appeal a decision on their submission if they believe the decision was unfair. To appeal a decision, please submit a letter to the Managing Editor at Provide the details about the nature of the appeal and indicate why the decision is viewed as unfair. The letter should be sent within 10 days after the date when the Author was notified about the decision. The Managing Editor of the journal will forward the manuscript and relating information to the Editor.

The Editor will review all the relevant documentation related to the submission, may consult the Editors or Reviewers and may appoint the new Reviewers to evaluate the manuscript before making a decision. The subsequent decision of the Editor will be final.

Publication of Corrections and Additions

In case a small part of the paper published in the Journal proved to contain flawed data or sufficient (not minor) mistakes resulted by author’s genuine error, the Editors of the journal may consider the publication of a Corrigendum.

If authors of a paper request an addition of a sufficient information after the paper was published, Editors of the journal may consider the publication of an Addendum. The Addendum will be published only if the Editors decide that it improves the representation of the research results sufficiently and is crucial for the understanding of a significant part of the paper.

All of the Addenda and Corrigenda should be submitted by Corresponding Authors supported by an approval letter signed by all of the co-authors. Addenda are subject to consideration by Editors and upon their positive decision are published in the upcoming volume of the journal.
