In one embodiment, the input circuit includes a receiver circuit that generates a data signal based on a pair of differential data signals. The technique selects an area within a scene that is to glow to produce a selected area image, generates glow using the selected area image to produce a glowing area image, and then adds the glowing area image to the scene to provide the glow effect. As a result, it may become difficult for auto-doping to be induced, even with no protective film formed on a back surface of the wafer. The antenna may include the support structure, which may be at a second end of the length of the upper arm and may support the upper arm. The invention further relates agonists and antagonists and to screening methods for identifying agonists and antagonists of CaHK1 polypeptide activity. The cable clamp is configured to clamp to a corrugated outer conductor of a cable, wherein the housing engages the cable clamp in an interference fit to form an integrated structure.
