      abstract     = {The non-equilibrium structural and dynamical properties of
                      a semiflexible polymer confined in a cylindrical
                      microchannel and exposed to a Poiseuille flow is studied by
                      mesoscale hydrodynamic simulations. For a polymer with a
                      length half of its persistence length, large variations in
                      orientation and conformations are found as a function of
                      radial distance and flow strength. In particular, the
                      polymer exhibits U-shaped conformations near the channel
                      center. Hydrodynamic interactions lead to strong
                      cross-streamline migration. Outward migration is governed by
                      the polymer orientation and the corresponding anisotropy in
                      its diffusivity. Strong tumbling motion is observed, with a
                      tumbling time which exhibits the same dependence on Peclet
                      number as a polymer in shear flow. Copyright (C) EPLA, 2010},
