      abstract     = {Worm-like filaments that are propelled homogeneously along
                      their tangent vector are studied by Brownian dynamics
                      simulations. Systems in two dimensions are investigated,
                      corresponding to filaments adsorbed to interfaces or
                      surfaces. A large parameter space covering weak and strong
                      propulsion, as well as flexible and stiff filaments is
                      explored. For strongly propelled and flexible filaments, the
                      free-swimming filaments spontaneously form stable spirals.
                      The propulsion force has a strong impact on dynamic
                      properties, such as the rotational and translational mean
                      square displacement and the rate of conformational sampling.
                      In particular, when the active self-propulsion dominates
                      thermal diffusion, but is too weak for spiral formation, the
                      rotational diffusion coefficient has an activity-induced
                      contribution given by vc/ξP, where vc is the contour
                      velocity and ξP the persistence length. In contrast,
                      structural properties are hardly affected by the activity of
                      the system, as long as no spirals form. The model mimics
                      common features of biological systems, such as microtubules
                      and actin filaments on motility assays or slender bacteria,
                      and artificially designed microswimmers.},
