Following publication, concerns were raised regarding the peer-review process related to the publication of this article [1]. Adhering to our standard procedure, the Editorial Board conducted an investigation which determined that, while the peer-review process does comply with MDPI’s Editorial process policy (https://www.mdpi.com/editorial_process), the contribution of one of the four reviewers does not comply with MDPI’s Guidelines for Reviewers (https://www.mdpi.com/reviewers#_bookmark11) nor the expectations of the Editorial Board. As a result, the Editorial Board has decided to remove the contribution of one of the reviewers from the open peer-review record (https://www.mdpi.com/1420-3049/28/19/6982/review_report) and, following discussion with the authors, have removed the citations (references [4,5] in the original publication) recommended by this reviewer from this publication [1]. The Editorial Board has confirmed that the publication of this paper in its modified form is in line with their expectations and MDPI’s Editorial Process policy.

In the original publication [1], the Conflicts of Interest statement of Qinyan Zhang was not included.
