To further expand the readership and accelerate the development of this journal, the publisher’s committees decided to jointly organize a Chinese version (http://cn.usp-pl.com/index.php/hlxk). The Chinese version will be published and distribute worldwide simultaneously. At the same time, the editorial board members of the journal will automatically become the board member of the Chinese version. In addition, the articles published in this journal will be translated and published in the Chinese version, which have been supported and recognized by most of the board members and authors. However, we appreciate any board members or authors could inform us if you are unwilling to synchronize this promotional activity. We will respect your wish by removing your name from the website of the journal in Chinese version.

Thank you!

Editorial Office
