摘要:
A digital data processing apparatus has plural processing cells, each with a memory element that stores data page made up of plural subpages. At least one of the cells includes a CPU that can request access to a data subpage. A memory manager responds to selected data access requests by (i) allocating, within the memory local to the requesting CPU, exclusive physical storage space for a data page associated with the requested subpage, and (ii) storing the requested subpage in that allocated space. The apparatus recombines data pages and deallocates them on the basis of usage and access state. The apparatus also accesses data asynchronously with respect to execution of instructions by the CPU.
摘要:
A multiprocessor digital data processing system comprises a plurality of processing cells arranged in a hierarchy of rings. The system selectively allocates storage and moves exclusive data copies from cell to cell in response to access requests generated by the cells. Routing elements are employed to selectively broadcast data access requests, updates and transfers on the rings.

摘要:
The present invention is directed to the identification of a biomarker specifically located in the plasma membrane of pancreatic beta cells. It was selected by a Systems Biology approach on Massively Parallel Signal Sequencing datasets obtained in human islets and Affymetrix microarray datasets on human islets, purified rat primary beta and non beta cells and insulinoma cells. Based on a set of specific features the biomarker is a unique candidate for imaging and targeting strategies to study the pancreatic beta cell mass in health and disease (T1 D, T2D, pancreatic cancers, obesity, islet transplantation, beta cell regeneration). The five specific features of the selected biomarkers are: 1) Preferentially expressed in pancreatic islets as compared to surrounding tissues; 2) Higher expression in pancreatic beta cells than in pancreatic alpha cells or than in other islet non-beta cells; 3) Expression levels in pancreatic beta cells are higher or comparable to glucokinase which is an enzyme specifically expressed in the pancreatic beta cell; 4) Located in the membrane and as such targetable with antibodies, peptides or small molecules which allows imaging, targeting and immunohistochemistry; and 5) Expression is not induced during the process of inflammation of the beta cell mass and the protein is not enriched in T-cells and dendritic cells or in other cells participating in the inflammation process.
