Ab initio no core shell model
TLDR
In this paper, a non-perturbative ab initio no core shell model (NCSM) was proposed to solve the properties of nuclei exactly for arbitrary nucleon-nucleon (N N ) and N N + ǫ − three-N n interactions with exact preservation of all symmetries.About:

Microscopic investigation of the 8 Li(n ,γ ) 9 Li reaction
TL;DR: In this paper, the authors used the no-core shell model with continuum (NCSMC) with chiral nucleon-nucleon and three nucleon interactions as input to calculate the low-energy nuclear scattering and reactions.

A new single-particle basis for nuclear many-body calculations
TL;DR: In this paper, the authors proposed a new single-particle basis, directly linked to the nucleon-nucleon interaction, which has the proper asymptotic behavior at large distances and does not contain the continuum which would pose severe convergence problems in nuclear many body calculations.

Bremsstrahlung emission from nuclear reactions in compact stars
Abstract: Bremsstrahlung emission of photons during nuclear reactions inside dense stellar medium is investigated in the paper. For that, a new model of nucleus is developed, where nuclear forces combine nucleons as bound system in dependence on deep location inside compact star. A polytropic model of stars at index $n=3$ with densities characterized from white dwarf to neutron star is used. Bremsstrahlung formalism and calculations are well tested on existed experimental information for scattering of protons of light nuclei in Earth. We find the following. (1) In neutron stars a phenomenon of dissociation of nucleus is observed --- its disintegration on individual nucleons, starting from some critical distance between this nucleus and center of star with high density. We do not observe such a phenomenon in white dwarfs. (2) In the white dwarfs, influence of stellar medium imperceptibly affects on bremsstrahlung photons. Also, we have accurate description of bremsstrahlung photons in nuclear reactions in Sun. (3) For neutron stars, influence of stellar medium is essentially more intensive and it crucially changes the bremsstrahlung spectrum. The most intensive emission is from bowel of the star, while the weakest emission is from periphery.

CP Violation in the Renormalizable Theory of Weak Interaction
TL;DR: In this article, it was shown that no CP-violating interactions exist in the quartet scheme without introducing any other new fields, and that the strong interaction must be chiral SU ( 4) X SU( 4) invariant as precisely as the conservation of the third component of the iso-spin.

Unitary Symmetry and Leptonic Decays
TL;DR: In this article, an analysis of leptonic decays based on unitary symmetry for strong interactions and the V-A theory for weak interactions is presented, and an explanation for the observed predominance of the LAMBDA yields + e/sup -/ + nu decay over the lamBDA /sup −/ yields n + e /sup + n decay.

TL;DR: The capacity to generate cardiomyocytes in the adult human heart suggests that it may be rational to work toward the development of therapeutic strategies aimed at stimulating this process in cardiac pathologies.

Local phenomenological nucleon-nucleon potentials
TL;DR: Hard (infinitely hard) and soft (Yukawa) core potentials have been fit to Yale and Livermore phase parameters and low-energy data as discussed by the authors, and it is found that neither the short-range behavior of the potentials nor the central-to-tensor ratio in the 3 S 1 - 3 D 1 state is well determined by the data.
