There were two similar series of burst waiting time experiments carried out on Godiva-II and Caliban respectively analyzed for neutron initiation study, unfortunately both the strength spontaneous fission source given in published papers are not consistent with data U-235 U-238. In this paper, discrepancies U-238 from different references reviewed clarified correct calculated respectively, then...

Cf sources are especially interesting for calibrating passive multiplicity counters without the need for Pu because: they are genuinely point-like and being lightly encapsulated offer a nearly isotropic unperturbed fission spectrum of neutrons for all practical purposes they can be considered as a pure source of spontaneous fission neutrons which considerably simplifies interpolation. That is t...

Through as yet undefined proteins and pathways, the SUMO-targeted ubiquitin ligase (STUbL) suppresses genomic instability by ubiquitinating SUMO conjugated proteins and driving their proteasomal destruction. Here, we identify a critical function for fission yeast STUbL in suppressing spontaneous and chemically induced topoisomerase I (Top1)-mediated DNA damage. Strikingly, cells with reduced ST...
