ABSTRACT
We study an effective integrable nonlinear model describing an electron moving along the axis of a deformable helical molecule. The helical conformation of dipoles in the molecular backbone induces an unconventional Rashba-like interaction that couples the electron spin with its linear momentum. In addition, a focusing nonlinearity arises from the electron-lattice interaction, enabling the formation of a variety of stable solitons such as bright solitons, breathers, and rogue waves. A thorough study of the soliton solutions for both focusing and defocusing nonlinear interaction is presented and discussed.

Polycythemia vera is classified with myelogenous leukaemia, agnogenic myeloid metaplasia and primary thrombocythemia as a myeloproliferative syndrome. Cutaneous symptoms have been reported with polycythemia vera, including facial plethora, aquagenic pruritus, urticaria, purpura, Sweet's syndrome and pyoderma gangrenosum. However, polycythemia vera associated with systemic sarcoidosis has been rarely reported. An unusual case of polycythemia vera associated with cutaneous sarcoidosis is described.
