A formulation of a sparingly water-soluble, crystalline pharmaceutically active agent wherein the active agent is converted to and stabilized in its amorphous form as a solid solution of a normally hydrophobic vehicle is described. More particularly, the invention relates to a scheduler and an associated algorithm for distributing bandwidth over data traffic directed to output ports and received in various traffic classes and flows. Some further embodiments provide for searching a universe of patent documents by patent document, claim, limitation, class, or element. Preferably, a pin passes through a bore in the handle and apertures in the sleeve to removably maintain the handle within the sleeve. An auxiliary coolant supply path supplies coolant to a sample, located in use in the sample holder at the DNP working region, through at least one aperture in the inner bore tube wall at the DNP working region. The antenna includes a first conductor section electrically coupled to a first feeding point, a second conductor section electrically coupled to a second feeding point, and a near-field radiation control structure adapted to control characteristics of near-field radiation generated by the antenna.
