Time-Reversal Invariance Violation in Heavy and in Few-body Nuclei
Time reversal invariance violating (TRIV) effects in neutron scattering are
very important in a search for new physics, being complementary to neutron and
atomic electric dipole moment measurements. In this relation, a sensitivity of
TRIV observables to different models of CP-violation and their dependencies on
nuclear structure, which can lead to new enhancement factors, are discussed.Comment: talk at PANIC1
Hierarchical Data Representation Model - Multi-layer NMF
In this paper, we propose a data representation model that demonstrates
hierarchical feature learning using nsNMF. We extend unit algorithm into
several layers. Experiments with document and image data successfully
discovered feature hierarchies. We also prove that proposed method results in
much better classification and reconstruction performance, especially for small
number of features. feature hierarchies
Time Reversal Invariance Violating and Parity Conserving effects in Proton Deuteron Scattering
Time reversal invariance violating parity conserving (TVPC) effects are
calculated for elastic proton deuteron scattering with proton energies up to
MeV. Distorted Wave Born Approximation is employed to estimate TVPC matrix
elements, based on hadronic wave functions, obtained by solving three-body
Faddeev-Merkuriev equations in configuration space with realistic potentials
