In a review just published in Nature Materials, researchers take aim at the oldest principle in electronics: Ohm's law.

Tulsa Weather: Unsettled pattern lingers through 4th of July weekend Scattered shower and storm chances will continue off and on through the holiday weekend. Any isolated heavier thunderstorms ...

A central pattern generator (CPG) is a neuronal network in which interconnected excitatory and inhibitory neurons produce an oscillating, rhythmic output in the absence of sensory feedback. CPGs ...

The optimal linear quadratic controller is usually designed based on a Riccati equation. However, when the Riccati is irregular, the problem becomes much more difficult since it is not clear what ...

In this paper, we design an active four-wheel steering optimal controller with linear quadratic regulator (LQR), and optimize it using an improved particle swarm algorithm (PSO) for the difficult ...
