Title: Sequential pattern memory searching and storage management technique
Inventor: SHAW ALEXANDER JOHN GOODWIN
IPC: G06F17/30
Filed: 1996-09-30
Abstract: The adaptive sequential pattern memory search technique only examines the contents of a subset of the total number of memory locations in each search for information representative of a character string. The subset includes a plurality of storage locations and each examination is performed in one concurrent read operation. If the character string is not matched, the memory must be updated tostore information representative of the unmatched string. This updating process selects one location from the subset for storing this representative information. Advantageously, an indicator of when each stored representative information lastmatched a character string is maintained and utilized in the selection process. In addition, to avoid operational errors associated with outputting invalid information from the "child" of a previously discarded "parent", an indication of the time each stored entry is created is utilized to remove such invalid information as it is detected in the updating process.

Title: Sensory and motor neuron derived factor (smdf)
Inventor: HO WEI-HSIEN
IPC: C12N5/0793
Filed: 1995-11-08
Abstract: Isolated SMDF, isolated DNA encoding SMDF, and recombinant or synthetic methods of preparing SMDF are disclosed. SMDF contains a .beta.-type EGF-like domain and a N-terminal sequence which is distinct from all neuregulins reported so far. SMDF, when expressed in recombinant cell culture, activates tyrosine phosphorylation of the HER2/neu receptor in human breast cancer cells and displays mitogenic activity on Schwann cells. Northern blot and in situ hybridization analysis show that SMDF differs from other neuregulins in that it is nervous tissue specific, and is very highly expresssed, in comparison to other neuregulins, in the human and rat spinal cord motor neurons and sensory neurons.
