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 (or an explanation has been provided in Comments to the Editor).
  • The submission file is a PDF file. (The source file is also recommended to be submitted. The illustrations and figures are of high resolution and quality).
  • The text adheres to the stylistic and bibliographic requirements outlined in the Author Guidelines.
  • The formatting and style are as in the sample file in doc.
  • References closely follow the recommended format (see sample file in doc).
  • Where available, DOIs or URLs have been provided for the references.

Author Guidelines

Manuscripts should be submitted in English through our online system in PDF format and also in Word as a “source file”. Manuscripts are accepted for review on the understanding that the same work has not been published or submitted elsewhere and that all the authors have given their approval for the submission of the paper. Only manuscripts meeting all the formal requirements will be considered for publication.

Here is an MS Word sample file and description for preparing the manuscript, which should be submitted in this style.


A correctly compiled manuscript should contain the following items: title; if it is long, an abbreviated title for running heads on the odd pages, consisting no more than 50 characters (including spaces) and having no abbreviations; an informative abstract of at most 150 words, which is definitely not longer than the first column of the template; 3-6 keywords. Since the abstract and keywords of an accepted paper will be disseminated electronically, it should make minimal use of mathematical symbols and should not contain displayed formulas or any reference to the article or its Reference list. The abstract and keywords will be offered for databases and Internet search engines.


In the following, all illustrations (pictures, diagrams, photographs) are referred to as figures. Figures should be uploaded in separate files. Bitmap images are expected as separate files in jpg, png, gif or tiff formats, vector graphics in eps or pdf formats. Please do not create line drawings with the built-in features of Microsoft Word as we shall need these drawings in separate files.

It is essential that the bitmap images have sufficient resolution to allow faithful reproduction (300 dpi or more). To determine the optimum resolution (width x height) of an 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 x 1000 pixel resolution and should be at least 600 x 600. Please do not increase the resolution by simple upsampling, the text and lines must be sharp and readable.

The dimensions of the figures have strict limitations: the maximum width of them in a column is 89.5 mm, the maximum width for a two-column picture is 183 mm, and for a wide picture with side-caption is 120 mm. So try to keep lettering in a figure resized for the manuscript in a readable but moderate size (ideally equivalent to 8-10 pt).


Bibliography (References) should be complete. Each item must have proper and not misunderstandable data (see the sample Word file or its PDF version for examples). 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 http://www.crossref.org/SimpleTextQuery/ (you need to register first). DOIs must be given for conference papers, too.

The bibliography style for Mendeley users:




The source file of the manuscript, the figures and the pictures as separate files are needed after the acceptance of the paper for copyediting. The preferred formats for pictures are jpg (moderate compression!), gif, tif, png, maybe pdf. Do not convert your vector graphics into raster format, just submit the original in a separate file.
