Statistical modeling of data sets by neural-network techniques is offered as an alternative to traditional semiempirical approaches to global modeling of nuclear properties. New results are presented to support the position that such novel techniques can rival conventional theory in predictive power, if not in economy of description. Examples include the statistical inference of atomic masses a...

We present and discuss a systematic calculation, based on two-loop chiral perturbation theory, of the pion-nuclear s-wave optical potential. A proper treatment of the explicit energy dependence of the off-shell pion self-energy together with (electromagnetic) gauge invariance of the Klein-Gordon equation turns out to be crucial. Accurate data for the binding energies and widths of the 1s and 2p...

Translation arrest leads to an endonucleolytic cleavage of mRNA that is termed no-go decay (NGD). It has been reported that the Dom34:Hbs1 complex stimulates this endonucleolytic cleavage of mRNA induced by translation arrest in vivo and dissociates subunits of a stalled ribosome in vitro. Here we report that Dom34:Hbs1 dissociates the subunits of a ribosome that is stalled at the 3' end of mRN...

We have determined theoretically the rest mass of the muon neutrino at 50 milli-eV and the rest mass of the electron neutrino at 5 meV, as well as , to 1% accuracy, the ratio of the masses of the stable elementary particles which decay by weak decays. We assume that the particles of the neutrino branch consist of a cubic, isotropic nuclear lattice, held together by the weak nuclear force. The e...

The partial width of the decay D s → D s π going through the violation of isotopical symmetry is computed with respect to the partial width of the radiative decay D s → D s γ in the effective quark model with chiral U(3)× U(3) symmetry incorporating Heavy quark effective theory (HQET) and Chiral perturbation theory at the quark level (CHPT)q. We investigate a sensitivity of the ratio R0 = Γ(D ∗...

The status of the theoretical description of the neutrino-nuclear interaction for low and intermediate energies is reviewed and its results are compared with the existing data. Particular emphasis is on C, the ingredient of liquid scintillator, and on O, the main component of the water Čerenkov detectors. First, I show that the data on the exclusive process populating the ground state of N are ...

A possible model independent test of the theoretically calculated nuclear matrix elements of 0νββ-decay is proposed. The test can be accomplished if 0νββ-decay of three (or more) nuclei is observed. The selection of the nuclei for the next generation of 0νββ-decay experiments should be done taking into account also considerations regarding the possibility to test the nuclear matrix element calc...
