The Open Researcher and Contributor Identifier (ORCID) serves as a unique academic identity for researchers, ensuring a one-to-one correspondence for each individual. The application of ORCID allows for swift and precise identity verification, safeguarding authors' rights and facilitating the dissemination and traceability of research findings.

Starting from March 2016, our journal has incorporated the ORCID in the author information section. We kindly request that both the first author and corresponding authors register at http://orcid.org to obtain their free ORCID.
