Multiplex network science and multiscale system dynamics: an approach to assessing the resilience of interdependent installations and infrastructure environments under compound extreme disruptions
Integrated modeling for resilient installations and infrastructure under extreme disruptions Background: Installations such as airports, military bases, and logistics hubs are increasingly vulnerable to disruptions from extreme weather, rising sea levels, and targeted cyber-physical attacks. These hazards often occur simultaneously or in rapid succession,...

Sealable Microvalve That Can Be Repeatedly Opened and Sealed
ink;color: #0000FF;text-decoration: underline; } INV-1243 Background The typical structure for a MEMS microvalve includes an orifice and a moveable plate that can be actuated to press against the orifice. When the plate does not press against the orifice, fluid can flow through the orifice and therefore through the valve. When the plate is pressed...
