  text: <jats:title>Abstract</jats:title><jats:p>We consider a geodesic billiard system
    consisting of a complete Riemannian manifold and an obstacle submanifold with
    boundary at which the trajectories of the geodesic flow experience specular reflections.
    We show that if the geodesic billiard system is hyperbolic on its trapped set
    and the latter is compact and non-grazing, the techniques for open hyperbolic
    systems developed by Dyatlov and Guillarmou (Ann Henri Poincaré 17(11):3089–3146,
    2016) can be applied to a smooth model for the discontinuous flow defined by the
    non-grazing billiard trajectories. This allows us to obtain a meromorphic resolvent
    for the generator of the billiard flow. As an application we prove a meromorphic
    continuation of weighted zeta functions together with explicit residue formulae.
    In particular, our results apply to scattering by convex obstacles in the Euclidean
    plane.</jats:p>

    silver setae (hair-like structures). Their appearance was explained by geometric
    optics and total internal reflection. The setae also increase the emissivity of
    the ant, as they form an effective medium. This work provides additional data
    on microstructural details of the setae that are used to simulate the scattering
    of an individual seta to explain their influence on the optical properties. This
    is achieved by characterization of their structure using light microscopy and
    scanning/transmission electron microscopy. How the microstructural features influence
    scattering is investigated wave-optically within the limits of finite-difference
    time-domain simulations from the ultraviolet to the mid-infrared spectral range
    to elucidate the optical effects beyond ray optics and effective medium theory.
    The results show that Mie scattering plays an important role in protecting the
    ant from solar radiation and could be relevant for its thermal tolerance.

  text: We investigate bifurcations in feedforward coupled cell networks. Feedforward
    structure (the absence of feedback) can be defined by a partial order on the cells.
    We use this property to study generic one-parameter steady state bifurcations
    for such networks. Branching solutions and their asymptotics are described in
    terms of Taylor coefficients of the internal dynamics. They can be determined
    via an algorithm that only exploits the network structure. Similar to previous
    results on feedforward chains, we observe amplifications of the growth rates of
    steady state branches induced by the feedforward structure. However, contrary
    to these earlier results, as the interaction scenarios can be more complicated
    in general feedforward networks, different branching patterns and different amplifications
    can occur for different regions in the space of Taylor coefficients.

  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>The defining
    feature of active particles is that they constantly propel themselves by locally
    converting chemical energy into directed motion. This active self-propulsion prevents
    them from equilibrating with their thermal environment (e.g. an aqueous solution),
    thus keeping them permanently out of equilibrium. Nevertheless, the spatial dynamics
    of active particles might share certain equilibrium features, in particular in
    the steady state. We here focus on the time-reversal symmetry of individual spatial
    trajectories as a distinct equilibrium characteristic. We investigate to what
    extent the steady-state trajectories of a trapped active particle obey or break
    this time-reversal symmetry. Within the framework of active Ornstein–Uhlenbeck
    particles we find that the steady-state trajectories in a harmonic potential fulfill
    path-wise time-reversal symmetry exactly, while this symmetry is typically broken
    in anharmonic potentials.</jats:p>"

    we prove that the multiplicity of the Pollicott-Ruelle resonance of the geodesic
    flow on perpendicular one-forms at zero agrees with the first Betti number of
    the manifold. Additionally, we prove that this equality is stable under small
    perturbations of the Riemannian metric and simultaneous small perturbations of
    the geodesic vector field within the class of contact vector fields. For more
    general perturbations we get bounds on the multiplicity of the resonance zero
    on all one-forms in terms of the first and zeroth Betti numbers. Furthermore,
    we identify for hyperbolic manifolds further resonance spaces whose multiplicities
    are given by higher Betti numbers.\r\n</jats:p>"
