AB  - In the present work, we study the nonlinear dynamics of microtubules, the basic components of the eukaryotic cytoskeleton. We introduce a two-component model describing tangential oscillations of dimers. A crucial nonlinear differential equation is solved using continuum approximation. We show that the dynamics of microtubules can be explained in terms of kink and antikink solitary waves. We used two mathematical procedures, that is the tangent hyperbolic function method and, more general, the simplest equation method. It is shown that both procedures bring about equal solutions. © 2021

AB  - We here study nonlinear dynamics of microtubule (MT). A so-called u - model is explained in detail. A single longitudinal degree of freedom per MT subunits is assumed. It is known that a continuum approximation of a basic discrete dynamical equation of motion enables existence of kink and antikink solitons along MT. In this paper we use semi- discrete approximation for this equation and show that modulated solitonic waves could propagate as well. We suggest possible biological implications of these waves. Also, a detailed parameter analysis is performed. (C) 2016 Elsevier Inc. All rights reserved.

We demonstrate that only one of the JEFs can be used while the remaining two do not represent the solutions of the crucial differential equation. We show that a kink-type soliton moves along MTs. Besides this solution, we also discuss a few more solutions that may or may not have physical meanings. Finally, we show what kind of ODE can be solved by using JEFs.

AB  - We here present a model of nonlinear dynamics of microtubules (MT) in the context of modified extended tanh-function (METHF) method. We rely on the ferroelectric model of MTs published earlier by Sataric et al. [1] where the motion of MT subunits is reduced to a single longitudinal degree of freedom per dimer. It is shown that such nonlinear model can lead to existence of kink solitons moving along the MTs. An analytical solution of the basic equation, describing MT dynamics, was compared with the numerical one and a perfect agreement was demonstrated. It is now clearer how the values of the basic parameters of the model, proportional to viscosity and internal electric field, impact MT dynamics. Finally, we offer a possible scenario of how living cells utilize these kinks as signaling tools for regulation of cellular traffic as well as MT depolymerisation. (C) 2012 Elsevier Ltd.

AB  - Possible modification of the phonon spectra due to the presence of small-polaron arising on account of vibron (amid-I quanta) self-trapping in hydrogen-bonded molecular chains is discussed. We predict that small-polaron effect should produce characteristic temperature variation of phonon frequencies and small-polaron binding energy. These effects should be observed in the experiments such as measurements of the speed of sound and infrared absorption spectra of molecular crystals which open an interesting possibility for the indirect confirmation of the existence of self-trapped states in molecular chains. Infrared absorption spectra may be especially interesting in that sense since the anticipated temperature variation of binding energy would be observed as a shift of the position of the unconventional (temperature dependent) peak in the IR absorption spectrum towards the position of the normal (temperature independent) one.

AB  - We study the conductivity of the linear molecular chains taking into account the changes of phonon spectra due to the small–polaron effect. It was found that the phonon hardening may lead to a considerable enhancement of the band as well as hopping conductivity. Character and the degree of these changes are determined by the values of the basic physical parameters of system, coupling constant and adiabatic parameter, and temperature as well. In particular: the increase of adiabatic parameter intensifies the hardening of phonon spectrum which in turn leads to a significant increase of the small–polaron conductivity. Quite on the contrary the increase of the coupling constant has the opposite tendency. The rise of temperature has practically the same consequences. This is the consequence of the increase of the effective coupling constant with the rise of temperature.

AB  - A simple model pseudopotential, particularly suitable for energy band calculations in elementary semiconductors, is presented. It includes the Veljković-Slavić's general model pseudopotential and phenomenological correction. This correction represents a sum of spherical Bessel functions of higher order with the coefficients obtained by fitting the form factor of the pseudopotential to the experimental values of the transition energies around the energy gap. The band structures of Si, Ge, and α-Sn are calculated and agree well with the experimental data. This pseudopotential is tested by calculating the resistivity of liquid Si, Ge, and Sn.
