We show that the oscillatory driving of crystal surfaces can induce pattern formation or smoothening. Depending on driving conditions, step bunching and meandering, mound formation, or surface smoothening may be seen in the presence of a kinetic asymmetry at the steps or kinks. We employ a step model to calculate the induced mass flux along misoriented surfaces, which accounts for surface dynam...

We study the control of modulational instability and pattern formation in a nonlinear dissipative feedback system with a periodic modulation of the material refractive index. We use a one-dimensional photonic lattice in a single-mirror feedback configuration and identify three mechanisms for pattern control: bandgap suppression of instability modes, periodicity induced pattern modes, and orient...

We present some numerical results obtained from a simple individual-based model that describes clustering of organisms caused by competition. Our aim is to show that, even when a deterministic description developed for continuum models predicts no pattern formation, an individual-based model displays well-defined patterns, as a consequence of fluctuation effects caused by the discrete nature of...

In the traditional E-type approach to d-(onkey)-pronouns, these pronouns are interpreted as definite descriptions that contain a bound i-(ndividual)-variable (Evans, 1977; Cooper, 1979; Heim, 1990). Elbourne (2001, 2002); Büring (2004) have recently proposed a variant of the E-type approach which dispenses with i-variable binding for donkey anaphora resolution altogether, deriving covariance vi...
