Computer Science and Technologies

Original papers that have not been previously presented and that describe new technical contributions to the areas covered by the technical descriptions in the aforementioned category will be accepted for presentation.

Accepted papers will be published in IEEE/Xplore in addition to conference technical digest. The authors will also have a chance to publish an extended, full-length version of the paper presented at MOC2025 in a special issue of the JJAP, which is an international journal published by the Japan Society of Applied Physics and IOP publishing. The papers can partially include the MOC2025 paper and will be published in 2026.
