I do not believe Dr. Nakayama committed fraud, since she accepts the lab leak of COVID-19. She simply did not know about the description of the FCS insertion in the DEFUSE proposal. This is often the case with Japanese scientists, who are generally not very proficient in English.
Replying to @hkakeya
It is clear from his/her posts that @EmniENakayama is an ignoramus, a fraud, or, both.
