By default, figures appear in colour online, which may black\white in print. Therefore, a reference to colour coding in both captions and main text should be avoided unless absolutely essential for the description of a figure.

Only articles written in English are accepted for submission. The language must be sufficiently clear to allow for the effortless understanding of the scientific content. Otherwise, the manuscript will not be considered further by the editorial board. If an author repeatedly submits the same manuscript without significant improvement in the basic clarity and readability of the presentation, the manuscript may be definitively rejected by the editorial board on these grounds.
