  Polymer translocation has long been a topic of interest in the field of
biological physics given its relevance in both biological (protein and DNA/RNA
translocation through nuclear and cell membranes) and technological processes
(nanopore DNA sequencing, drug delivery). In this work, we simulate the
translocation of a semiflexible homopolymer through an extended pore, driven by
both a constant and a time-dependent end-pulled force, employing a model
introduced in previous studies. The time dependence is simplistically modeled
as a cosine function, and we distinguish between two scenarios for the driving
-- longitudinal force and transversal force -- depending on the relative
orientation of the force, parallel or perpendicular respectively, with respect
to the pore axis. Beside some key differences between the two drivings, the
mean translocation times present a large minimum region as function of the
frequency of the force that is typical of the Resonant Activation effect. The
presence of the minimum is independent on the elastic characteristics of the
polymeric chains and reveals a linear relation between the optimum mean
translocation time and the corresponding period of the driving. The mean
translocation times show different scaling exponent with the polymer length for
different flexibilities. Lastly, we derive an analytical expression of the mean
translocation time for low driving frequency, which clearly agrees with the
simulations.
