Background: One fascinating frontier in nuclear physics is the study of exotic nuclei. The deformed relativistic Hartree-Bogoliubov theory continuum (DRHBc), which simultaneously includes superfluidity, deformation, and effects, can provide proper descriptions for both stable In a previous work [Zhang et al., Phys. Rev. C 102, 024314 (2020)], DRHBc based on point-coupling density functionals was developed calculation, previously accessible only light nuclei, extended all even-even nuclei...
The occurrence of the bubble-like structure has been studied, in light pseudospin degeneracy, within relativistic Hartree-Fock-Bogoliubov (RHFB) theory. It is concluded that charge/neutron predicted to occur mirror system {$^{34}\mathrm{Si},\phantom{\rule{0.16em}{0ex}}^{34}\mathrm{Ca}$} commonly by selected Lagrangians, due persistence $Z(N)=14$ subshell gaps above which $\ensuremath{\pi}(\ensuremath{\nu})2{s}_{1/2}$ states are not occupied. However, for popular candidate $^{46}\mathrm{Ar}$,...
Abstract The relativistic mean field (RMF) model has achieved great success in describing various nuclear phenomena. However, several serious defects are common. For instance, the pseudo-spin symmetry of high- l orbits is distinctly violated general, leading to spurious shell closures and . This leads problems structure properties, including structures, masses, etc. Guided by restoration [Geng et al. , Phys. Rev. C, 100: 051301 (2019)], a new RMF Lagrangian DD-LZ1 developed considering...
This study aimed to isolate and investigate five novel xanthine oxidase (XO) inhibitory peptides FF, YF, WPW, WPDARG YNVTGW from alkaline protease hydrolyzate (F0) of Pacific cod processing by-product bone-flesh mixture (CBFM2). F0 was separated by dextran gel chromatography obtain F1, F2, F3, F4 F5 components. The components with the highest XO activity were analyzed identified using liquid chromatography-tandem mass spectrometry (LC-MS/MS), further screened molecular docking Autodock Vina....
The role of the pseudospin symmetry in inversion ground-state spin Cu isotopes is investigated within covariant density functional theory (CDFT). PC-PK1 gives a good agreement with observed properties odd-A 69−79Cu. In particular, at A=75 reproduced nicely, which can be explained by level crossing between proton partners π2p3/2 and π1f5/2. It found that plays dominant evolution energy splittings partners. By comparing results nonrelativistic DFTs, our studies suggest essential to shell...
Starting from the Bonn potential, relativistic Brueckner-Hartree-Fock (RBHF) equations are solved for nuclear matter in full Dirac space, which provides a unique way to determine single-particle potentials and avoids approximations applied RBHF calculations space with positive-energy states (PESs) only. The uncertainties of PESs only investigated, importance is demonstrated. In empirical saturation properties symmetric reproduced, obtained equation state agrees results based on Green's...
Microscopic optical potentials based on realistic nucleon-nucleon interactions are important for describing the scattering phenomenology involving nuclei far away from valley of nuclear stability. The authors construct a new potential by combining relativistic Brueckner-Hartree-Fock theory with microscopic description density profile target nucleus. model provides good reproduction proton data five nuclei, opening up interesting perspectives applications to exotic including setting reliable...
Half-life of proton radioactivity spherical emitters is studied within the scheme covariant density functional (CDF) theory, and for first time potential barrier that prevents emitted extracted with similarity renormalization group (SRG) method, in which spin-orbit along others turn out to be non-negligible can derived automatically. The spectroscopic factor significant also from CDF calculations. estimated half-lives are found good agreement experimental values, not only confirms validity...
Tensor force is identified in each meson-nucleon coupling the relativistic Hartree-Fock theory. It found that all couplings, except $\ensuremath{\sigma}$-scalar one, give rise to tensor force. The effects of on various nuclear properties can now be investigated quantitatively, which allows fair and direct comparisons with corresponding results nonrelativistic framework. binding energies evolutions $Z,\phantom{\rule{0.16em}{0ex}}N=8,\phantom{\rule{0.16em}{0ex}}20$, 28 magic gaps are studied....
The long-standing controversy about the isospin dependence of effective Dirac mass in ab initio calculations asymmetric nuclear matter is clarified by solving relativistic Brueckner-Hartree-Fock equations full space. symmetry energy and its slope parameter at saturation density are ${E}_{\text{sym}}({\ensuremath{\rho}}_{0})=33.1$ MeV $L=65.2$ MeV, agreement with empirical experimental values. Further applications predict neutron star radius...
Nucleon effective masses in neutron-rich matter are studied with the relativistic Brueckner-Hartree-Fock (RBHF) theory full Dirac space. The neutron and proton for symmetric nuclear 0.80 times rest mass, which agrees well empirical values. In matter, mass of is found to be larger than that proton, neutron-proton splittings at saturation density predicted as $0.187\ensuremath{\alpha}$ $\ensuremath{\alpha}$ being isospin asymmetry parameter. result compared other ab initio calculations...
The authors derive a new density-dependent point-coupling covariant density functional (PCF-PK1) with exchange terms that are local and can be included in standard relativistic mean-field calculation. This saves considerable amount of computing time over Hartree-Fock calculations nonlocal potentials. PCF-PK1 is obtained by fitting nuclear matter finite nuclei, including the results...
Chitosanases are valuable enzymatic tools in the food industry for converting chitosan into functional chitooligosaccharides (COSs). However, most of chitosanases extensively characterized produced a low degree polymerization (DP) COSs (DP = 1-3, LdpCOSs), indicating an imperative enhancements product specificity high DP COS >3, HdpCOSs) production. In this study, chitosanase from
