For the first time, scientists have observed the iconic Shapiro steps, a staircase-like quantum effect, in ultracold atoms.

Abstract: In this article, linear and nonlinear event-triggered extended state observers are designed for a class of uncertain random systems driven by bounded noise and colored noise. Two event ...

Abstract: State estimation for nonlinear models has been a longstanding challenge in the field of signal processing. Classical nonlinear filters, such as the extended Kalman filter (EKF), unscented ...

The body overseeing Australia’s biggest electricity markets has scaled back its forecasts for new wind farms and transmission lines as rising costs and community unrest take a toll. But the Australian ...

Imagine standing on top of a mountain. From this vantage point, we can see picturesque valleys and majestic ridges below, and streams wind their way downhill. If a drop of rain falls somewhere on this ...
