Web7 feb. 2024 · Fission yeasts are an ancient group of fungal species that diverged from each other from tens to hundreds of million years ago. Among them is the preeminent model organism Schizosaccharomyces pombe, which has significantly contributed to our understandings of molecular mechanisms underlying fundamental cellular processes. WebThe notation in the table belowis such that is the cross-section for thermal or fast neutron absorption, of which fissions and captures; epithermal cross-sections use the same notation style, replacing with ; is the mean number of neutrons emitted by a fission event; is the net number of fission-neutrons yielded per neutron absorbed; is the …
