usually the Abstract is not the place to introduce acronyms and their meaning. For the sake of clarity and to help the reader find the meaning of acronyms used in this paper, it might be better to write down the full list of all acronyms used and in alphabetical order immediately after the Keywords. In addition, the Authors should evaluate the need for acronyms if used only once in the paper. Clarity is an important matter here, because the paper is of interest to a much wider audience, not a little circle of specialists.
