    "abstract": "A new mechanism for spiral vortex nucleation in nongradient reaction\ndiffusion systems is proposed. It involves two key ingredients: An Ising-Bloch\ntype front bifurcation and an instability of a planar front to transverse\nperturbations. Vortex nucleation by this mechanism plays an important role in\ninducing a transition from labyrinthine patterns to spiral turbulence. PACS\nnumbers: 05.45.+b, 82.20.Mj",
