The journal is owned by MedCore Press, which retains copyright of the overall compiled journal and its compiled issues. For individual articles, authors retain copyright and grant MedCore Press and Tsinghua University Press non-exclusive rights to publish, distribute, and disseminate the articles in all formats (including digital and print) globally. To ensure open access to research, authors agree to make their articles available under open access licences, which define the terms of reuse for the public. This approach aligns with the core principle of open access: enabling immediate, permanent, and free access to scholarly work while protecting authors’ rights.
