Resumen:
Information theoretic quantities are useful tools
to characterize symbolic sequences. In this work, we use the
Jensen-Shannon divergence to study symbolic binary sequences that
represent the stationary state of a lattice-gas model describing the
traffic of monomeric kinesin KIF1A. More specifically, the
constructed binary sequences represent the state of a microtubule
protofilament at different adenosine triphosphate (ATP) and KIF1A
motor concentrations in the cytosol. The model presents some
stationary regimes with phase coexistence. By using the
Jensen-Shannon divergence, we develop a method of analysis that
allows us to identify cases in which phase coexistence occurs and,
for these cases, to locate the position of the interphase that
separates the regions with different phase.
