A new view of nonlinear water waves: the Hilbert spectrum [PDF]
Annual Review of Fluid Mechanics, 1999 We survey the newly developed Hilbert spectral analysis method and its applications to Stokes waves, nonlinear wave evolution processes, the spectral form of the random wave field, and turbulence.

On more general boundary value problems involving sequential fractional derivatives
Advances in Difference Equations, 2019 We investigate the existence of solutions for new boundary value problems of Caputo-type sequential fractional differential equations and inclusions supplemented with nonlocal integro-multipoint boundary conditions.

On comparison of the estimators of the Hurst index and the diffusion coefficient of the fractional Gompertz diffusion process [PDF]
, 2016 We study some estimators of the Hurst index and the diffusion coefficient of the fractional Gompertz diffusion process and prove that they are strongly consistent and most of them are asymptotically normal. Moreover, we compare the asymptotic behavior of
