    "abstract": "Theoretical and numerical studies are presented of the nonlinear amplitude\nmodulation of dust-acoustic (DA) waves propagating in an unmagnetized three\ncomponent, weakly-coupled, fully ionized plasma consisting of electrons,\npositive ions and charged dust particles, considering perturbations oblique to\nthe carrier wave propagation direction. The stability analysis, based on a\nnonlinear Schroedinger-type equation (NLSE), shows that the wave may become\nunstable; the stability criteria depend on the angle $\\theta$ between the\nmodulation and propagation directions. Explicit expressions for the instability\nrate and threshold have been obtained in terms of the dispersion laws of the\nsystem. The possibility and conditions for the existence of different types of\nlocalized excitations have also been discussed.",
