Simultaneous submission issues

 The editorial office has encountered two incidents in which the authors submitted their manuscript to multiple journals at the same time. This type of behavior is called simultaneous submission or concurrent submission, which is considered unethical. This kind of behavior will greatly waste the time and effort of reviewers and editors. At the same time, it is possible that the same manuscript will be published by multiple journals. In the end, even if such articles are published, they will be withdrawn by the editor in time. The authors can only submit their manuscript to one journal at the same time.
