This paper develops an asymptotic theory for estimated change-points in linear and nonlinear time series models. Based on a measurable objective function, it is shown that the estimated change-point ...

Asymmetric interactions between different species of molecules have previously been demonstrated to result in self-organized ...

Using nonlinear impulse-response functions, we evaluate the dynamics implied by the threshold model. These suggest that shocks have a larger effect on output in the "tight" credit regime than is ...

A new model suggests how gravitational waves created by the collision between black holes spread and interact within the fabric of space-time.

The development of the nonlinear optical nanoparticles synthesized by laser ablation are summarized, which demonstrates its capability for enhanced performance and multiple functions.
