Query: Transport of Finite Size Self-Propelled Particles Confined in a 2D
  Zigzag Channel with Gaussian Colored Noise   The directional transport of finite size self-propelled Brownian particles
confined in a 2D zigzag channel with colored noise is investigated. The
noises(noise parallel to x-axis and y-axis), the asymmetry parameter {\Delta}k,
the ratio f(ratio of the particle radius and the bottleneck half width), the
selfpropelled speed v0 have joint effect on the particles. The average velocity
of self-propelled particles is significantly different from passive particles.
The average velocity exhibits complicated behavior with increasing
self-propelled speed v0
