Query: Stokesian dynamics of pill-shaped Janus particles with stick and slip
  boundary conditions   We study the forces and torques experienced by pill-shaped Janus particles of
different aspect ratios where half of the surface obeys the no-slip boundary
condition and the other half obeys the Navier slip condition of varying slip
lengths. Using a recently developed boundary integral formulation whereby the
traditional singular behaviour of this approach is removed analytically, we
quantify the strength of the forces and torques experienced by such particles
in a uniform flow field in the Stokes regime. Depending on the aspect ratio and
the slip length, the force transverse to the flow direction can change sign.
This is a novel property unique to the Janus nature of the particles.
