Disclosed is a process for identifying clones having a specified activity of interest, which process comprises generating one or more expression libraries derived from nuclei acid directly isolated from the environment; and screening said libraries utilizing a fluorescence activated cell sorter to identify said clones. In some embodiments, control circuitry determines whether a selected media asset belongs to a series where an order is assigned to media assets in the series. An attribute based access control policy is generated from remaining identified attributes to derive logical rules that grant or deny access. In one embodiment the magnetizable panel may be pivotally mounted on the front cover of the binder, so that it may be folded over to expose the back of the binder for accessible erasing. The present invention applies parametric methods to provide superior wavemember resolution. The modulo processor includes a pipeline processing portion that iteratively computes a running partial modulo product using the operands of a modulo mathematic argument to obtain one or more final partial modulo products.
