A method for generating amplified terahertz radiation includes inducing a first volume of a gas to produce a seed plasma and emit pulsed seed terahertz radiation by focusing an optical seed beam in the first volume. In one embodiment, the method comprises measuring a drug level in fluid of a subject and normalizing said measured drug level as a function of one or more parameters associated with the subject. Such exhibition information is automatically generated during a monitoring of projection system equipment. The system memory-side prefetcher also includes a prefetch injection unit to insert prefetches into the memory controller based on the detected one or more patterns.
