Modification of Semi-Analytical Method Applied System of ODE

open access: yes, 2020
In this study, we modify the well-known semi-analytical method called the Homotopy Analysis Method (HAM), such that the right-hand side of a given ODE system is decomposed to a sum of analytical functions.

Modified Exp-Function Method to Find Exact Solutions of Ionic Currents along Microtubules

open access: yesMathematics, 2022
A number of solitary wave solutions for microtubules (MTs) are observed in this article by using the modified exp-function approach. We tackle the problem by treating the results as nonlinear RLC transmission lines, and then finding exact solutions to ...
