There may not necessarily be only one corresponding author for a SCI journal article, and the specific number is not fixed. This is because different SCI journals have different policies regarding the number of corresponding authors. For SCI journals that only accept one corresponding author, if the article lists multiple corresponding authors, the first corresponding author will automatically be selected. For SCI journals that accept two corresponding authors, two corresponding authors can be listed. The same applies to other requirements. In other words, the number of corresponding authors listed by the authors must comply with the regulations of the target SCI journal. The first author of an SCI paper is the person who has made the greatest contribution to the experiment and writing of the article, and is the person whose name appears first in the author list. However, in cases of collaboration, there can be situations where there are co-first authors. There is no specific rule regarding the number of co-first authors, and it is greatly related to the workload, length of the article, regulations of the publishing journal, and recognition by the institutions. Generally speaking, having 2-4 first authors for an SCI paper is the most common
