Please check your submissions and accepted manuscripts in the production process carefully to avoid any mistakes. Once the paper is published, the journal will correct only errors that affect its content in a significant way. These do not include typos, spelling mistakes, grammatical errors, or any other small errors unless they alter the meaning of the text. Corrections can only be made within 6 months of the original publication. Corrections may be issued online as either a corrigendum (an author error) or as an erratum (a production error).
