Vectors and a method for the identification of affector RNA molecules, such as ribozymes, external guide sequences, anti-sense RNA, and triple helix-forming RNA, that inhibit expression of target RNA molecules are disclosed. A bit pattern Yj at a symbol Xj within the first test error pattern is flipped to obtain a second test error pattern, wherein i\u2260j. In response to a request for a task from one of the first terminals, the processing system processes communicates with a resource controller of a resource identified by the request and allocates a portion of a resource used for processing the task as part of the allocated resource. This operation makes it easy to re-enter bills in the space. When sufficient force is applied in the cap removal direction, part of the ring is severed, such as the tabs or the fins.
