The APEX Editorial Board has decided to change the processes of proofreading and payment of publication charges. The galley proofs for the article will be provided by IOP Publishing (IOPP) and the author should return corrections to IOPP. (Please note that IOPP will also handle the language editing; however, no tracked changes will be provided.) In addition, invoice for the publication charges as well as Open Access APC will be sent by IOPP to the author and the payment recipient will become IOPP. This change will be adopted for the publications in issue 1 of 2019 onward.
