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...

  Background: Several studies have examined the effects of folic acid fortification on the occurrence of orofacial clefts. This study was carried out to evaluate the impact of flour fortification with folic acid on oral clefts in Northern Iran.   Methods : In this hospital based study from March 2006 to September 2009, we screened the total number of live births at all hospitals in Golestan pro...
