Abstract We calculate the spectrum of massive Dirac fermions in graphene presence an inhomogeneous magnetic field modeled by a step function. find analytical universal relation between bandwidths and propagating velocities modes at border region, showing how, tuning mass term, one can control speed these traveling edge states.

Small organisms (e.g., bacteria) and artificial microswimmers move due to a combination of active swimming and passive Brownian motion. Considering a simplified linear three-sphere swimmer, we study how the swimmer size regulates the interplay between self-driven and diffusive behavior at low Reynolds number. Starting from the Kirkwood-Smoluchowski equation and its corresponding Langevin equati...

Self-adaptive software systems are capable of adjusting their behavior at run-time to achieve certain functional or QoS goals. Such systems typically employ analytical models specified at design-time to assess their characteristics at run-time and make the appropriate adaptation decisions. However, prior to system’s deployment, engineers often cannot foresee the changes in the environment, requ...
