Submission Preparation Checklist

As part of the submission process, authors are required to check off their submission's compliance with all of the following items, and submissions may be returned to authors that do not adhere to these guidelines.
  • The submission has not been previously published, nor is it at another journal for consideration.
  • The submission file is a PDF file. (The source file of the original document is recommended to be submitted. The illustrations and figures are included.)
  • The text adheres to the stylistic and bibliographic requirements outlined in the Author Guidelines.
  • The text is single-spaced by default, using a 10-point font. If you submit also the source file for reviewing, this is fine; otherwise, please submit another PDF file with double spacing and using 12-point font for body text as an auxiliary file. The text employs italics, rather than underlining; all illustrations, figures, and tables are placed within the text at the appropriate points, rather than at the end.
  • The illustrations and figures are of high resolution and quality.
  • References closely follow the recommended format (see sample file in docx and pdf).
  • Where available, DOIs or URLs have been provided for the references.
  • All authors, affiliations and email addresses are properly specified in the submission web page.
  • Authors are willing to participate in the peer review process, meet the deadlines, and to provide retractions or correction of mistakes if needed.

Author Guidelines


Manuscripts are accepted for review on the understanding that a similar work has been neither published nor submitted elsewhere and that all the authors have given their approval for the submission of the paper. The submitting author must provide contact information (full name, email address, ORCID ID, institutional affiliation, and mailing address) for all co-authors. The names must be uploaded in the same form and sequence as they appear on the first page of the manuscript (Note that co-authors are not required to register in the online system). The submitting author takes the responsibility of notifying all co-authors that the manuscript is being submitted. Deletion of an author after the submission requires a confirmation email to the assigned editor.
Manuscripts should be submitted in English through our online system in PDF format and also in Word as a "source file". Only manuscripts meeting all the formal requirements will be considered for review and possible publication.
Correspondence regarding the peer review, and/or acceptance of papers should be directed to the Editorial Contact.
Correspondence regarding the preparation of the final version, usage of the MS Word Template, copyediting and typesetting of papers should be directed to the Publisher Contact.
If you have general questions concerning the handling of the online OJS system (e.g. registration, login, paper submission), please contact

Here is a MS Word Template and a sample file (in docx and in pdf) for preparing the manuscript, which should be submitted in this style. A research article may only be longer than 8 pages in exceptional cases, while the limit of 12 pages applies to review articles.
LANGUAGE: Papers must be submitted in English using the American spelling. Expressions in other languages should be translated to English everywhere in the text, equations, figures, and tables.
TITLE: main words in the title start with a capital letter, articles and conjunctions with lowercase letters.
AUTHORS' names: Please specify the full author name with non-abbreviated first (given) and last (surname) names. ORCID ID is not shown in the PDF versions of the papers. If the authors provide the ORCID ID, this information is presented on the web page of the paper.
AFFILIATIONS contain the name of the company or institute (department, faculty, university) postal address, and email address.
The ABSTRACT should be concise and no longer than 250 words and should not contain citations.
Give 3–5 KEYWORDS start with lowercase character and are separated by comma.
All SECTIONS are numbered consecutively except for the "Acknowledgement" and "References". Please refer to sections as "Section 1" etc. (not as "Chapter").
Titles may have at most three hierarchical levels:
1 Title
1.1 Subtitle
1.1.1 Sub-subtitle
Should further levels be necessary, additional title lines must have italic font and no number with no empty line before them.
The text may employ italics, rather than underlining. All illustrations, figures, and tables are placed within the text at the appropriate points, rather than at the end.

In the following, all illustrations (pictures, diagrams, photographs) are referred to as figures. Upon acceptance figures should also be uploaded in separate files. File names should be of the form "Fig01.jpg" or "Fig02.eps" etc. Please do not include captions as part of the figures. If your figure has more parts, include the labels "(a)" and "(b)" etc. as part of the artwork. Bitmap images are expected in jpg, png or tiff formats, vector graphics in eps or pdf formats. Please do not create line drawings with the built-in features of Word or Excel as we shall need these drawings in separate files. Please export the drawings in a vector graphics format (PDF/EPS) or in a bitmap image format (JPG/PNG, TIFF) of high resolution. It is essential that the bitmap images have sufficient resolution to allow faithful reproduction (300 dpi or more). To determine the optimum resolution (width × height) for a 300 dpi image, measure the width and height as it appears in your document (in millimeters), and then multiply those two values by 12. For example, a square image of 80 mm wide, i.e. having the width of a single column, the optimal size is about 1000 × 1000 pixel resolution and should be at least 600 × 600. Please do not increase the resolution by simple upsampling, the text and lines must be sharp and readable. Figures should not have extra white borders and must be properly cropped.
The dimensions of the figures have strict limitations: the maximum width in a column is 83.5 mm and the maximum width for a two-column picture is 174 mm. Keep lettering in a figure resized for the manuscript in a readable but moderate size (ideally equivalent to 8–10 pt).
The definition of the notation (legend) for diagrams should also be sent together with the diagram as an image file. Alternatively, explain the notation in the caption of the figures but without graphic symbols. Some examples of such explanation are "marked with gray column/triangle/striped area".
Figures are numbered consecutively. Please refer every figure from the text. When referencing your figures within your paper, use the abbreviation "Fig." even at the beginning of a sentence. Please always write an informative caption that explains the significance of the figure.
The layout and form of Schemes are identical to those of specified for figures. They should be separate high resolution image files. Scheme title is expected below the scheme, centered, and without abbreviation (e.g. "Scheme 1").

Algorithms are supposed to have the form of a table. The title of the Algorithm is in the first row of the table, aligned left. If necessary, it may contain vertical lines or simple arrows but not complex drawings. Schemes and Algorithms should be explicitly referred in the text: (e.g.: Scheme 10, Algorithm 10).

Tables cannot be images. Tables are to be referred as "Table 1" etc. in the text, do not write "the table above" or "the table below". Tables get consecutive numbers similarly to figures. Please refer every table explicitly in the text. Please always write an informative caption that explains the significance of the table. The table caption is centered above the table.

Use the Equation Editor or MathType (Math Equations Editor | MathType (, and never insert an equation as an image or a text. Number equations consecutively with equation numbers in parentheses flushed to the right margin. Use the tab to position the formula and the equation number. Punctuate equations when they are part of a sentence. Refer to equations as "Eq. (1), but not as "equation (1)" or as "(1)", except at the beginning of a sentence, e.g. "Equation (1) is ...". When referring to mathematical/physical/chemical expressions, the Eq. term is used, that is, Eq. is a general term applicable not only to equations but also for inequalities, constraints, etc.
Whenever possible, inline mathematics should also be typed with the equation editor. Be sure that the symbols in your equation have been defined before the equation appears or immediately following.

Symbols and Character Formats

  • Italicize symbols but not units of measure (variable T might refer to temperature, but T is the unit tesla).
  • Lowercase Greek letters are italic (ω), uppercase Greek letters (Ω) are regular.
  • Texts (if, then and, or etc.) and acronyms (DG etc.) are not slanted in equations.
  • Lowercase abbreviations are slanted even in subscripts.
  • Mathematical functions (min, max, sin, cos), dimensionless numbers (e.g..: Re – Reynolds number), and chemical symbols (H2O) are not slanted.
  • Vectors are in italic and bold fonts, but the components of vectors are only italic.

Appendix, Supplement and Nomenclature
Appendix is placed after the References. Appendices are denoted as Appendix A, Appendix B, etc. Numbering of tables, figures, algorithms, schemes, and equations starts from 1 and is distinguished with letter A, B, C ... etc.
For example:
Fig. A1 (first figure in Appendix A), Table B2 (second table in Appendix B), Algorithm C3 (third algorithm in Appendix C), Scheme D4 (fourth scheme in Appendix D), Eq. (E5) (fifth equation in Appendix E).
Supplement in a separate file can also be published on-line. Numbering in the supplement starts from 1 and is distinguished with letter S: Fig. S1, Table S1, Eq. (S1).
Nomenclature is between the last section and References.

Authors take the full responsibility for the accuracy of their references. Please add the DOI number or URL of a full-text version if it exists. The DOI of journal papers can be found in page (you need to register first). DOIs must be given for conference papers too. Insert DOI as active link in the following format (example):[DOI].
Each citation in the text is included in the reference list. Each item of the reference list is cited in the text.
All publications cited in the text should be referred to by a number in square brackets (e.g. [1]). The references are arranged in the order of citations, in the list of References. Note that only one reference belongs to one number. The in-text citation style is as follows: For parenthetical citations we enclose the number of the reference, thus: [1]. Sequential parenthetical citations are enclosed in square brackets and separated by commas, thus [1, 2] or [3–5]. In sentences, refer simply to the reference number, as in [3]. Do not use "Ref. [3]" or "reference [3]". At the beginning of a sentence use the author names instead of "Reference [3]," e.g. "Smith and Smith [3] show ...".
Do not create "Cross-references" in your Word file.
In the list of references author names are expected in the "Family, C." format where "C" is the initial of the first name. Do not use "and" or "et al.", give the names of each author (Smith, A. D., Small, B., Big, C.). Provide the complete title of publication (title of paper, book, book chapter, standard, patent). Do not abbreviate journal or conference names, e.g. write "Transactions on Medical Imaging" instead of "Trans Med Imaging".
