The nuclear exosome and the nonsense-mediated mRNA decay (NMD) pathways have been implicated in the degradation of distinct unspliced transcripts in Saccharomyces cerevisiae. In this study we show that these two systems can act sequentially on specific unspliced pre-mRNAs to limit their accumulation. Using steady-state and decay analyses, we show that while specific unspliced transcripts rely m...

Study of the neutrinoless double beta decay, 0νββ, includes a variety of problems of nuclear structure theory. They are reviewed here. The problems range from the mechanism of the decay, i.e. exchange of the light Majorana neutrino neutrino vesus the exchange of some heavy, so far unobserved particle. Next, the proper expressions for the corresponding operator are described that should include ...

2014 Nuclear radii for mass numbers between A = 140 and 252 have been computed from 121 alpha decays between ground states of even-even nuclei. We use for that the two-body solution for the square well potential that we gave recently. The computed radii obey the A 1/3 law and they are consistent with the precise radii obtained from electron scattering. These two sets of radii show structures wh...
