Dynamic load economic dispatch problem (DLED) is important in power systems operation, which is a complicated nonlinear constrained optimization problem. It has nonsmooth and nonconvex characteristics when generator valve-point effects are taken into account. This paper proposes an improved...

Second-order diffusion process can not only model integrated and differentiated diffusion processes but also overcome the difficulties associated with the nondifferentiability of the Brownian motion, so these models play an important role in econometric analysis. In this paper, we propose a...

In this paper, we develop local M-estimation for the infinitesimal moments in the jump-diffusion model based on discrete-time observations. The consistency and asymptotic normality of the local M-estimators for the infinitesimal moments are obtained under mild conditions. The simulation studies...

The paper investigates how the availability heuristic of individual stocks affects equity returns, where the availability heuristic is measured by the irrational signal in the fractal dimension. Our evidence support that the availability heuristic can positively predict the short-term expected...
