A Kohn-Sham scheme based multi-task neural network is elaborated for the supervised learning of nuclear shell evolution. The training set composed single-particle wave functions and occupation probabilities 320 nuclei, calculated by Skyrme density functional theory. It found that deduced distributions, momentum charge radii are in good agreements with benchmarking results untrained nuclei. In p...

As follows from the energies of single-particle states in 40Ca, 90Zr and 208Pb nuclei the contribution of many-particle NN forces to the nuclear single-particle potential is at least the sum of repulsive and attractive parts resulting from three-particle and four-particle forces respectively. In addition the specified nucleon density distributions in the above nuclei are determined from both th...

In hadrons and nuclei at very small x, parton distributions saturate at a scale Qs(x). Since the occupation number is large, and Qs(x) >> ΛQCD, classical weak coupling methods may be used to study this novel regime of non–linear classical fields in QCD. In these lectures, we apply these methods to compute structure functions in deeply inelastic scattering (DIS) and the energy density of gluons ...

Quantum Monte Carlo calculationsof ground and low-lying excited states for nuclei with A 8 are made using a realistic Hamiltonian that ts NN scattering data. Results for more than 40 diierent (J ; T) states, plus isobaric analogs, are obtained and the known excitation spectra are reproduced reasonably well. Various density and momentum distributions and electromagnetic form factors and moments ...

The nuclear size radii, density distributions and elastic electron scattering charge form factors for Fluorine isotopes (17,19,20,24,26F) were studied using the radial wave functions (WF) of harmonic-oscillator (HO) potential free mean field described by spherical Hankel (SHF) core valence parts, respectively all aforementioned isotopes. parameters HO (size parameter ) SHF chosen to regenerate ...

Background: 3DCRT (three-dimensional conformal radiotherapy) and IMRT (intensity-modulated radiotherapy) has provided us with tools to delineate the radiation dose distribution of tumor targets. However, the precision of radiation can be compromised by respiratory motion, which usually limits the geometric and dosimetric accuracy of radiotherapy. The purpose of this study is to evaluate the imp...

introduction: varicocele is considered as a common cause of male infertility. the aim of this study was to evaluate the effects of varicocelectomy on sperm parameters, sperm membrane integrity and sperm nuclear maturity. materials and methods: in this study along with routine semen analysis, hypo-osmotic swelling test (host), and aniline blue staining for assessment of as 45 and 90 days after i...
