I can't find the article, and I can't read Hungarian, but how crazy is this.
I turned it up while searching PubMed for the bibtex citation for Szabo's 1980 mean first passage time article, since I don't really understand what the MFPT fuss is all about. No luck with the citation though, so I'll just have to use J. Chem. Phys.'s website directly :p.
