We study the stochastically driven conserved Kardar-Parisi-Zhang (CKPZ) equation with quenched disorders. Short-ranged disorders are found to be a relevant perturbation on pure CKPZ at one dimension and, as result, different universality class from appears emerge. At higher dimensions, disorder turns out ineffective influence universal scaling. This results in asymptotic long wavelength scaling...

In recent years, discrete wavelet transform (DWT) provides an useful platform for digital information hiding and copyright protection. Many DWT-based algorithms for this aim are proposed. The performance of these algorithms is in term of signal-to-noise ratio (SNR) and bit-error-rate (BER) which are used to measure the quality and the robustness of an embedded audio. However, there is a tradeof...

We study the problem of triviality in the four dimensional Nambu-Jona-Lasinio model with discrete chiral symmetry using both large-N expansions and lattice simulations. We find that logarithmic corrections to scaling appear in the equation of state as predicted by the large-N expansion. The data from 16 lattice simulations is sufficiently accurate to distinguish logarithmically trivial scaling ...
