  "abstract": "We study the tilt dependence of the pinning-depinning transition for an interface described by the anisotropic quenched Kardar-Parisi-Zhang equation in 2+1 dimensions, where the two signs of the nonlinear terms are different from each other. When the substrate is tilted by m along the positive sign direction, the critical force F_c(m) depends on m as F_c(m)-F_c(0) \\sim -|m|^{1.9(1)}. The interface velocity v near the critical force follows the scaling form v \\sim |f|^{\\theta}\\Psi_{\\pm}(m^2 /|f|^{\\theta+\\phi}) with \\theta = 0.9(1) and \\phi= 0.2(1), where f \\equiv F-F_c(0) and F is the driving force.",
