Query: Bidirectional transport and pulsing states in a multi-lane ASEP model   In this paper, we introduce an ASEP-like transport model for bidirectional
motion of particles on a multi-lane lattice. The model is motivated by {\em in
vivo} experiments on organelle motility along a microtubule (MT), consisting of
thirteen protofilaments, where particles are propelled by molecular motors
(dynein and kinesin). In the model, organelles (particles) can switch
directions of motion due to "tug-of-war" events between counteracting motors.
Collisions of particles on the same lane can be cleared by switching to
adjacent protofilaments (lane changes).
  We analyze transport properties of the model with no-flux boundary conditions
at one end of a MT ("plus-end" or tip). We show that the ability of lane
changes can affect the transport efficiency and the particle-direction change
rate obtained from experiments is close to optimal in order to achieve
efficient motor and organelle transport in a living cell. In particular, we
find a nonlinear scaling of the mean {\em tip size} (the number of particles
accumulated at the tip) with injection rate and an associated phase transition
leading to {\em pulsing states} characterized by periodic filling and emptying
of the system.
