    "abstract": "The order parameter model based on parametric Ginzburg-Landau equation is\nused to describe high acceleration patterns in vibrated layer of granular\nmaterial. At large amplitude of driving both hexagons and interfaces emerge.\nTransverse instability leading to formation of ``decorated\u0027\u0027 interfaces and\nlabyrinthine patterns, is found. Additional sub-harmonic forcing leads to\ncontrolled interface motion.",
