Boundary Stabilization for the Rayleigh Beam System under Event-triggered Controls

Siwen Wang, Yi Cheng, Yuhu Wu +2

In this paper, we propose two event-triggered control laws incorporating an eventtriggering mechanism to tackle the boundary stabilization for the Rayleigh beam system. Under this…

A 62-minute orbital period black widow binary in a wide hierarchical triple

Kevin B. Burdge, Thomas R. Marsh, Jim Fuller +30

Over a dozen millisecond pulsars are ablating low-mass companions in close binary systems. In the original "black widow", the 8-hour orbital period eclipsing pulsar PSR J1959+2048…
