Accelerators used for nuclear-physics research require megawatts of radio-frequency energy. They currently employ vacuum-tube power amplifiers or conventional solid-state amplifiers that are inefficient and therefore consume a great deal of prime power. Many other applications including semiconductor processing, cellular-telephone base station transmitters and military communication systems simila ...

The objective of lab-on-chip (LOC) is to integrate and perform multiple analytical processes on a microchip platform. So far, most LOC research has been focused on electrophoretic separations. Limited progress has been made on multi-process integration, due mainly to the lack of a robust and miniaturized pump that can deliver constant flow and be integrated with LOC devices. Microchip HPLC can and ...

ABSTRACT: As we move from a paper-based world into a digital environment, the internet will soon evolve from a virtual documentation system into a vibrant ecosystem of data where documents and human actors play an even smaller role. We are currently reaching a tipping point in history concerning data: more data is being manufactured by machines, servers, mobile devices, and software applications ...
