about ICCF21 I just uploaded our Abstract (to be presented in the plenary oral session) at ResearchGate. The number of DOI is: 10.13140/RG.2.2.16425.29287.
For Your convenience I upload the document also in attachment.
I hope it can be useful for a scientific discussion.
* BTW, for what I know, the number of abstracts arrived was 103.
