Information about Page Charge Exemption

Authors or their institutions are required to pay a publication charge when a paper is accepted. For details of the publication charges, please refer to General Information. However, the APEX Editorial Board may help authors who have genuine difficulty in paying the publication charge. This is only applicable when all the authors belong to institutions outside Japan. Such financial support is available to only a limited number of papers per year. Authors who wish to apply for such an exemption should send an application form for page charge exemption with the authorized signature of the author in charge of this application and the signature of the Department Head of the institution at the time of submission.

Authors applying for charge exemption shall be deemed to have consented to the conditions listed below:

  • The APEX Editorial Board will evaluate each application based on the importance of the research and the financial situation of the authors after the paper review process is finished. Therefore, the publication will be delayed if the authors apply for an exemption.
  • The application for an exemption does not affect the paper review process in any way.
  • If the paper is accepted for publication, however, it does not necessarily mean that it will be published with the exemption of the publication charge. If the application for exemption is not approved by the APEX Editorial Board, the authors will be requested to send the agreement for payment of the publication charge to the APEX Editorial Office within three weeks of the request by the APEX Editorial Division. Otherwise, the decision to accept the paper will be canceled unless a satisfactory reason is given.
  • If the exemption application is approved by the APEX Editorial Board, the authors will be exempted from the payment of the publication charge in accordance with this program.
  • An appeal or an inquiry against the non-approval of this application will NOT be undertaken.
  • There is NO possibility of a discount or partial exemption of the publication charge.

[NOTICE] Author(s) who wish to apply for a Publication Charge Exemption are requested to use the application form specifically prepared for the application. Even in this case, the authors are requested to complete and send the copyright transfer agreement form.
