Solitary extramedullary plasmacytomas are uncommon neoplasms. They occur most frequently in the upper aerodigestive tract and account for 4% of the nonepithelial tumors in this site. The evolution of… (More)
A description of fragmentation functions which satisfy the momentum and isospin sum rules is presented. We concentrate on the pion fragmentatio function, taking into account cascadelike processes in… (More)
The relativistic Faddeev equation for three quarks is solved in the SU( 2)f x SU( 3), NJL model to get the nucleon and delta states. We truncate the interacting two-body channels to the scalar and… (More)
Atrophy of laryngeal epithel at aged men can in model according to the literature lead back on prolongation of mitosis cycles. An increasing tendency of cornification and decreasing formation of pegs… (More)
Spin-dependent quark light-cone momentum distributions are calculated for a nucleon in the nuclear medium. We utilize a modified NJL model where the nucleon is described as a composite quark-diquark… (More)
This model attempts to consummate the biological processes of laryngeal epithel on a biophysical basis with the end of prediction optimally therapeutic methods.
The Collins effect describes the modulation of the hadron production by a transversely polarized quark with the sine of the polar angle, φ, between the produced hadron’s transverse momentum and the… (More)
