A radio using non-simultaneous frequency diversity includes: an antenna, a radio frequency module coupled to the antenna such that the radio frequency module is operable to transmit or receive radio frequency signals using the antenna, and a baseband module coupled to the radio frequency module. A III-V QWFET includes a gate stack which comprises a high-K gate dielectric layer disposed on an interfacial layer comprising a group III chalcogenide. Certain emulsion compositions as described in this specification posses the unique property of maintaining emulsion stability in wood preservatives during extended use in typical wood treatment processes. Alternatively, a wire stent may be joined with one or more tubes, thereby biasing the laminate to a cylindrical configuration. Recording of a recording track and a prepit is carried out by sequentially deflecting a single beam. Example pharmaceutical compositions of such liposomes, when administered to a subject, provide for increased contrast of extended duration, as measured by computed tomography, in the bloodstream and other tissues of the subject.
