Abstract: An assay system is useful for predicting recurrence and/or non-recurrence of colorectal cancer in a patient. The assay system is adapted to analyze a patient sample for quantitative expression of a prognostic genetic profile correlated with colorectal cancer recurrence. The profile includes the expression of the nucleic acid sequences of SEQ ID NOS: 1, 2, 3, 4, and 5.

Abstract: A fact acting automatic gain control system comprising a single or serial multistage arrangement. In one multistage embodiment (FIG. 1) each stage (13) has a first state with a predetermined gain and a second state with unity gain. The output of each stage determines what state is finally adopted although initially when a signal is input it is in the first state due to the action of a sequence controller (14). The predetermined gain values may comprise a binary sequence which descends in the direction towards the output. If the level detector (7) threshold is exceeded, the stage is set to the second state. A particular use of the system is to ensure burst mode pulses reaching a receiver are of similar amplitude. A similar arrangement can be employed for phase alignment ratther than gain control. In another multistage embodiment (FIG.
