✦ Synopsis

An improved solution for soliton excitations of a one-dimensional molecular-crystal model with the dispersion term is found. Under the approximation of neglecting the dispersion term, the improved solution tends to the usual polaron solution. We calculate the lattice, displacement of the self-trapped state, the self-trapped well of the electron, the density of current carried by soliton excitations and the width, the peak the effective mass and the binding energy of the soliton excitation in the model. The differences between the soliton excitation in the model and the usual polaron are pointed out.

Background Continuous hyperglycemia is implicated in the pathogenesis of chronic diabetic complications. It is not well known, however, how and to what extent the development of neuropathy is inhibited by blood glucose control in subjects with Type 2 diabetes. We investigated therefore the effects o
