Re:issue №4 The title of these blocks will be translated "by topic" means the authors believe that these links are somehow related to the original article. They are for the most part really connected, as in this article or the first block in the one you sent. Yes, some of them may seem unrelated to us, but this is not for us to decide, but for the authors of the article. If they put a link in this block (they are only in some articles, not in all), then they want to show this link to the reader and remove it incorrectly.
