Isospin Symmetry Violation in sd-Shell Nuclei
EPJ Web of Conferences, 2014 We construct a new set of isospin-nonconserving (INC) shell-model Hamiltonians and apply it (i) to study the isobaric-mass multiplet equation (IMME) beyond a quadratic form in the A = 35, 3/2+ quartet, (ii) to compute the isospin mixing corrections to ...

Isospin effect on nuclear stopping in intermediate energy Heavy Ion Collisions [PDF]
, 2002 By using the Isospin Dependent Quantum Molecular Dynamics Model (IQMD), we study the dependence of nuclear stopping Q_{ZZ}/A and R in intermediate energy heavy ion collisions on system size, initial N/Z, isospin symmetry potential and the medium ...

Isospin breaking corrections to meson masses and the hadronic vacuum polarization: a comparative study [PDF]
Journal of High Energy Physics, 2017 We calculate the strong isospin breaking and QED corrections to meson masses and the hadronic vacuum polarization in an exploratory study on a 64 × 243 lattice with an inverse lattice spacing of a−1 = 1.78 GeV and an isospin symmetric pion mass of mπ ...

ISOSPIN MIXING OF ISOSPIN-PROJECTED SLATER DETERMINANTS: FORMALISM AND PRELIMINARY APPLICATIONS [PDF]
International Journal of Modern Physics E, 2009 We report on the development of a new theoretical tool that allows for isospin projection of Slater determinants and we present its first applications. In particular, we determine the isospin mixing in ground states of N = Z nuclei and discuss its dependence on the size of the harmonic-oscillator basis used in the calculations.

Plant Direct, Volume 9, Issue 6, June 2025.ABSTRACT Tea plants (Camellia sinensis L.) use ammonium and nitrate as the main sources of nitrogen (N), but they respond differently to these two compounds. In this study, we investigated the effect of the ammonium:nitrate ratio on tea plant growth as well as N uptake and metabolism.

Nuclear isospin asymmetry in $\alpha$ decays of heavy nuclei
, 2016 The effects of nuclear isospin asymmetry on $\alpha$ decay lifetimes of heavy nuclei are investigated within various phenomenological models of nuclear potential for the $\alpha$ particle.

Molecular Oncology, Volume 19, Issue 5, Page 1452-1470, May 2025.Pancreatic ductal adenocarcinoma (PDAC) is a disease with very poor prognosis due to therapeutic limitations. We investigated the antitumor effects of cystatin A (CSTA) in PDAC murine models. We are first to confirm that CSTA enhances T helper type 1‐mediated antitumor effects through promotion of dendritic cells and M1 macrophage activity. CSTA can be

Heisenberg uncertainty inequality and breaking of isospin symmetry in atomic nuclei
Physical Review ResearchThe Heisenberg uncertainty inequality is used to derive a rigorous lower bound to the amount of isospin impurities in N=Z atomic nuclei, caused by the violation of isospin symmetry.

Search for isospin effects on nuclear level density
EPJ Web of Conferences, 2010 Studies on the isospin dependence of the level density have been recently reported in the literature for nuclei with 20 ≤ A ≤ 110. Corrections to the level density have been deduced which would imply a significant reduction of this quantity for nuclei ...
