It is relatively simple to check the duplication of small papers, and it is generally not necessary to check the duplication before publication. If you want to publish a small paper, you only need to review your advanced nature before submitting the paper or give it to your tutor, and adjust the sentence, word order and typesetting. After the paper is submitted, the editorial department will review the paper for the second time. After the review is completed, the paper will be checked again, so the work of checking the paper is undertaken by the editorial department, and individuals do not need to check the paper themselves.
