The present invention discloses a valve integrally associated with a microfluidic transport assembly that is useful for regulating the flow of a liquid sample through an analytical instrument such as, for example, a biosensor. A waveguide, feedline, probe or other means of excitation is electronically coupled to the dielectric to emit a radiation pattern for carrying analog or digital information. Furthermore, certain aspects may employ additional switching in the baseband domain in an effort to avoid, or at least reduce, switching glitches in the Rx caused by changing the cross switch configuration. A method of depositing material with a rotating cylindrical magnetron sputtering cathode apparatus comprising a radio frequency power supply and a cylindrical rotating cathode is also disclosed wherein the outer surface of the rotating cathode comprises a target material formed of an oxide. Relatively small broad concave leaflets are formed that display semi-pointed serrations. The captured image is compared with the second teaching model, and the second teaching model most closely resembling the captured image is selected.
