We understand that the authors have worked carefully preparing manuscripts, and we have carried out peer-review processes. However, sometimes there is the potential for published articles to be withdrawn or deleted for scientific reasons. It should not be done lightly and can only occur under extraordinary circumstances. Therefore, corrections, clarifications, retractions, and apologies when needed will be carried out with strict standards to maintain confidence in the authority of its electronic archives. Our commitment and policy are to maintain the integrity and completeness of important scientific records for researchers and librarians' archives.
