RECOMMENDATIONS ON THE CONTENT AND STRUCTURE OF THE ARTICLES

Publication forms

The editorial board of the journal accepts for consideration the author's materials, drawn up in the form of a review or an original article.

Reviews can cover any modern achievements related to the subject of the journal. Reviews should be written in such a way as to assist the reader in assessing emerging prospects and opportunities, as well as in finding publications containing key information about new developments. In the introductory part of the review, it is desirable to provide an explanation of the main tasks, concepts and terms. The reader of the review article should understand the need for an in-depth study of the problem using the bibliographic references provided for the article, so the review should not look like a listing of innovations and references to sources.

Original articles must correspond to the subject of the journal. The novelty and scientific significance of the work are checked by reviewers and the editor-in-chief. The information in the original article must be complete, allowing a specialist in this field to reproduce the results obtained by the authors. It is not recommended to present generally known information in the original articles. When submitting manuscripts, the authors are fully responsible for the fact that the presented research results are performed personally, comply with the norms of scientific ethics and are carried out on an open topic.

Volumes of published materials

Review articles can be up to 30 pages per issue. The publication of reviews in several issues takes place in agreement with the editor-in-chief. Authors of original articles are recommended to be up to 20 pages long.

Article title

Authors should give the article the most specific and informative title, if possible, not exceeding 20 words.

Annotations

Review and original articles should be accompanied by annotations giving an idea of ​​the essence and novelty of the published results. The abstract should be understandable before reading the article and should not contain links to any publications. The volume of the annotation should not exceed 10-15 lines. It is not recommended to break annotations into paragraphs.

UDC codes

The authors of the article indicate the UDC (for articles in Russian), which the publication corresponds to.

Keywords

Authors should indicate the set of keywords that best characterize the published research results. Keywords are used to automatically search for an article, for example in an electronic library. We recommend that authors choose no more than 10 keywords or phrases for their article.

Structure of Articles

Depending on the volume, the main text of the article can be structured into sections and paragraphs, like this article, or only into paragraphs. It is not recommended to give titles to sections and paragraphs that span more than two lines. A section should not consist of one paragraph.

Paragraphs can be two or more paragraphs. It is recommended for better perception to break the text into paragraphs no more than 10-15 lines in size.

Acknowledgments

In the last paragraph before the list of references, the authors have the right to express gratitude to those who provided substantial assistance in the work, or to indicate sponsorship and grants.

Bibliography

The list of references is an integral part of the article and is drawn up directly in the text of the article with the indication doi, if the publication is assigned a digital identifier. The list of references is formed in the order of reference to the sources in the text of the article.

A mandatory requirement is a complete translation of the bibliography into English for indexing an article in foreign databases.

The use of separate files with the bib, bbl and others extensions is not allowed.

Below is an example of the formatting of bibliography in Russian and English.

English translation

Authors of articles published in the journal in Russian must provide translated into English:

• surname, name, patronymic, academic degree, academic title of each author;
• the name, postal addresses of the organizations that are the main places of work of the authors, and their positions in these organizations;
• article title;
• annotation text;
• keywords.

REQUIREMENTS FOR REGISTRATION OF ARTICLES

Preparation of the article

The editors accept articles from authors prepared in the LATEX publishing system.

Authors of articles can use additional style files, for example algorithmx for a set of algorithms, etc. Additional style files must be explicitly included in the document preamble. Using your own styles is not recommended.

Articles prepared using Microsoft Word or other editors are accepted only in exceptional cases by the decision of the editors and will be published with a delay due to the translation of the original text into the LATEX publishing system and additional editorial revisions.

Typing requirements

The editors recommend following the typing rules set out in the Russian-language literature on the LATEX system.

We draw the attention of the authors to the following typing rules.

There should always be a space between the initials and the surname (A.A.Ivanov). In the title of the article, spaces are also placed between the initials: A. A. Ivanov.

The integer part of the number should be separated from the fractional part in the same way in the text of the article: either a comma or a period. On graphs and diagrams formed as a result of the work of programs, and in program listings, the integer part of the number from the fractional part can be separated by a dot.

The quotation marks should be in the form of "legs"; the use of "herringbones" is not allowed.

Dates must be typed in the format dd.mm.yyyy.

The period is not put after the section headings, table titles and figure captions, after a number of abbreviated names: s - second, g - gram, min - minute, d - day, mil - million, bil - billion, etc.

The period is placed at the end of the last sentence of the annotation, after the abbreviations: mon. - month, etc.

Multi-word abbreviations are separated by spaces, for example 760 mmHg. Art., with the exception of commonly used ones (i.e.).

References to figures and tables are separated by non-breaking spaces from the number (correct: Fig. 1, Table 2, incorrect: Fig.1, Tab.2).

Quotes and brackets are not separated by spaces from the words enclosed in them: (for U_max), (a); and not ( at U_max ), ( a ).

A non-breaking space is placed between the number or paragraph sign and the number: No. § 5.65.

Requirements for a set of formulas, theorems, etc.

a) all numbers are typed in straight type in formulas; b) all Roman script chars, including indices (for example, E_min); c) abbreviations of mathematical functions: sin, cos, lim, max.

For typing excluded formulas, it is recommended to use the equation environment with automatic continuous numbering. To suppress numbering, use the equation * environment.

The style file provides for the placement of summation indices, integration limits, etc. strictly above or below mathematical symbols.

Formulas that span one or more lines (so-called exclusion formulas) and are part of a sentence must obey the rules of punctuation.

The words "Theorem", "Collorary", "Lemma", "Asserrtion", "Proposition" are placed in the text of the article explicitly and are highlighted in bold, and the corresponding formulations are in italics.

The words "Proof", "Definition", "Remark" are in roman italic style, and the corresponding wording is in roman type.

It is recommended to carry out continuous numbering with Arabic numerals for theorems, definitions, etc.

Requirements for a set of program listings

#include 
int main (int argc, char *argv[])
{
#pragma omp parallel
	{
		printf("Message 1\n");
#pragma omp single nowait
		{
			printf("Some text\n");
		}
		printf("Message 2\n");
	}
}

Requirements for illustrations

Fig. 1. Classification of M. Flynn:
a) Single Instruction stream / Single Data stream;
b) Single Instruction stream / Multiple Data stream;
c) Multiple Instruction stream / Single Data stream;
d) Multiple Instruction stream / Multiple Data stream (with the permission of the authors)

1. The editors make minimal edits to the illustrations. In case of insufficient quality illustrations, the article is sent to the authors for revision.
2. The following dimensions of illustrations are recommended: a) no more than 165 mm wide and no more than 210 mm high (in the width of a text column); b) no more than 80 mm wide and no more than 140 mm high (half the column width); c) 145 mm high and 240 mm wide (illustration expanded 90° on the whole page).
3. Three types of illustrations are accepted: line drawings (graphs, diagrams, graphs, etc.), screenshots of the computer screen (for example, color visualization of the field obtained as a result of mathematical modeling) and photographs.
4. Line art is accepted in the form of PNG (raster) files with a resolution of 600 DPI at a 1:1 scale of the figure or in EPS format (vector images). The thickness of the thinnest line in the picture should not be less than 5px. It is recommended to use black for the main lines. Elements of the picture that are important for understanding should be highlighted in two or three colors, which are contrastingly reproduced in black and white printing. Recommended background color is white.
5. Photos are accepted in formats JPEG, PNG, TIFF with a resolution of 300 DPI. The image in the photo should be sharp, contrasting. Digital image processing should not raise doubts about the authenticity of the photograph.
6. The series of illustrations is intended for comparing graphs, assessing the influence of parameters, explaining trends, dynamics, etc. Drawings included in the series must be of the same size and resolution. The series must be completed with one floating object of the LATEX system. Each illustration in the series must be designated with a letter of the Russian alphabet (Fig. 1). Letters of illustrations in the series are recommended to be placed by the commands of the publishing system LATEX.
7. The editors draw your attention to the fact that the preliminary layout made by the authors often leads to a deterioration in the quality of the pictures, for example, due to the incorrectly set resolution when converting a picture to EPS format. The editors ask to provide, along with EPS files, the original "raw" files in the formats TIFF, PNG, JPEG without processing. If the picture is a screenshot from the computer screen, then it must be taken at the maximum window size and no longer scaled. Authors can make a copy of the figure in the format and sizes they need and insert it into the text of the article.
8. The editorial board of the journal does not require authors to deal with such technical issues as wrapping pictures with text and placing them on the page. The final layout is carried out by the technical editors of the journal.

Requirements for the design of tables

The editors recommend formatting tabular data using the LATEX publishing system. Highlighting table cells with color unnecessarily is not encouraged. The exception is tables obtained from the Internet or automated data processing systems in the form of screenshots.

For small tables it is recommended to use the tabularx environment. For layout of complex or large tables, additional style files may be required.

Requirements for captions of figures and tables

• Figures, tables, formulas, program listings, etc. must have consecutive numbering for each type of structural elements of the article.
• Signatures should be informative and concise. It is recommended that signatures be worded so that they do not span more than three lines.
• The caption for a series of illustrations should contain a common name for all figures in the series and a list of captions that specify each illustration (Fig. 1).

Links to figures, formulas, tables, sources

The editors do not recommend using manually typed links in the text of the article. To reduce the likelihood of errors in links in the text of the article, it is necessary to use the \label commands, which automatically save the counter values ​​for figures, tables, lists in a symbolic variable, and \ref, which creates a link by the variable name.

INTERACTION WITH THE EDITORS

Required documents

To publish an article, authors must provide:

1. a cover letter from the authors in electronic form and its scanned version with "live" signatures;
