Errata

Errata are short corrections to published articles. They may correct scientific errors which may result in misunderstandings but do not change the conclusions of the article, errors of omission (such as author names or references), or errors in the writing or publication process. Errata are subject to editorial approval. 

Please submit erratum requests, including a description of the error and its correction as well as a full citation of or link to the original article, to xbbjb2@bjmu.edu.cn
