Described is a technique for maintaining local cache coherency between endpoints using the connecting message fabric. One example method comprises exposing the substrate to an activated oxygen species and converting an exposed surface of the substrate into a continuous monolayer of a first dielectric material. The intake system includes an intake conduit extending along the engine body. The deposit, or portion thereof, is used at the destination resulting in uses, impacts, effects or subsequent transfers. Each device card includes an interface bridge for connecting to a respective asynchronous or synchronous device card connector.
