The decay rate of neutrinoless double beta (0νββ) decay contains terms from heavy particle exchange, which lead to dimension-9 (d = 9) six fermion operators at low energies. Limits on the coefficients of these operators have been derived previously neglecting the running of the operators between the high-scale, where they are generated, and the energy scale of double beta decay, where they are ...

General discard pathways eliminate unprocessed and irregular pre-mRNAs to control the quality of gene expression. In contrast to such general pre-mRNA decay, we describe here a nuclear pre-mRNA degradation pathway that controls the expression of select intron-containing genes. We show that the fission yeast nuclear poly(A)-binding protein, Pab2, and the nuclear exosome subunit, Rrp6, are the ma...

In this paper, a method to deal with proton decay in nuclear matter, previously published, ' is generalized in order to include effects arising from the nuclear surface. Although several theoretical estimates'~ indicate the (eventual) proton decay width in a nucleus to be rather similar to that of an isolated proton, things are different regarding the spectra of the emitted particles (both lept...

The decay heat rate of five spent nuclear fuel assemblies the pressurized water reactor type were measured by calorimetry at interim storage for in Sweden. Calculations performed 20 organizations using different codes and data libraries resulting 31 results each assembly, spanning most current state-of-the-art practice. calculations based on a selected subset information, such as operating hist...
