Abstract: The present invention relates to VEGF-C or VEGF-D materials and methods for promoting growth and differentiation of neural stem cells, neuronal and neuronal precursor cells, oligodendrocytes and oligodendrocyte precursor cells and materials and methods for administering said cells to inhibit neuropathology.

Abstract: The invention is in the realm of an information processing system including a central unit which includes several processors sending requests to several processors sending requests to several memories via an input interconnection and receiving responses from those memories via an output interconnection. To simplify the input interconnection when the number of processors and memories increases, a ring of stations equipped with a register is used. A request given by a processor is loaded into a station when that station is free or becomes free, If not the ring functions a fed back shift register. A station becomes free when the request contained in the station downstream is accepted by a memory. An analogous device can be used for the output interconnection. A notable application is vector processing.
