Query: Vortex Guidance and Transport in Channeled Pinning Arrays   We numerically examine vortices interacting with pinning arrays where a
portion of the pinning sites have been removed in order to create coexisting
regions of strong and weak pinning. The region without pinning sites acts as an
easy-flow channel. For driving in different directions with respect to the
channel, we observe distinct types of vortex flow. When the drive is parallel
to the channel, the flow first occurs in the pin free region followed by a
secondary depinning transition in the pinned region. At high vortex densities
there is also an intermediate plastic flow phase due to the coupling between
the weak and strong pinning regions. For driving applied perpendicular to the
channel, we observe a jammed phase in which vortices accumulate on the boundary
of the pinned region due to the vortex-vortex repulsion, while at higher drives
the vortices begin to flow through the pinning array. For driving at an angle
to the channel, depending on the filling we observe a drive-induced reentrant
pinning effect as well as negative differential mobility which occurs when
vortices move from the unpinned to the pinned portion of the sample.
