International Classification:

H01L 31/055
G02B 5/08

US Classification:

136247, 359850

Abstract:

Luminescent solar concentrator (LSC) devices are provided herein. The provided LSCs include devices having an oriented luminophore in at least one layer of the LSC device. Other LSC devices include LSCs having both a collector wave guide, incorporating a luminophore, and a transport wave guide, having no luminophore, into which luminesced light from the collector wave guide travels. Additionally, wave guides for use in LSCs are provided that include guided-wave plasmon-polariton modes for improved optical transmission within LSC devices. The devices provided herein, either alone, or in combination, provide improved LSC device performance, particularly with regard to overall device efficiency.

International Classification:

C12N 15/113

US Classification:

514 44 A

Abstract:

The present invention provides methods of treating diseases and disorders associated with aberrant erythropoiesis. Specifically, the present invention provides a method for treating polycythemia in a subject by administering an inhibitor of miR-451. Methods of increasing red blood cell count and treating anemia in a subject by administering miR-451 mimetics are also disclosed.

Appl. No.:

8/935242

Inventors:

Tony M. Brewer - Plano TX
David M. Patrick - Plano TX

Assignee:

Hewlett-Packard Company - Palo Alto CA

International Classification:

G06F 1214

US Classification:

711163

Abstract:

A computer memory management system that allocates each node's network cache into protected and unprotected regions. Nodes are previously configured into error containment cluster of nodes (ECCNs). Unprotected network caches may encache data accessed from any node's unprotected memory. Protected network caches may encache data accessed from nodes that are within the same ECCN, but only from a node's protected main memory. Memory address allocation techniques known in the art enable the system to know whether a processor's request for data will be found in protected or unprotected memory. Under the present invention, a node is able to first refer to network cache (protected or unprotected, as appropriate) in locating the data. If the data is not in cache, then the system refers to main memory. The present invention thus enables superior memory access advantages of cache memory techniques.

Assignee:

Atlantic Richfield Company - Los Angeles CA

International Classification:

F16L 1500

US Classification:

2853323

Assignee:

Hewlett-Packard Co. - Palo Alto CA

International Classification:

G06F 1214
G06F 1316

US Classification:

39520045

Abstract:

The multi-node multiprocessor system with globally shared memory is partitioned into groups of nodes called error containment clusters of nodes or ECCNs. The nodes would be partitioned such that an ECCN resides on a column of nodes or a row of nodes. Within each ECCN there is coherent memory sharing. Between the ECCNs, the communication is through a messaging protocol. The memory within each node is also partitioned into protected and unprotected memory. Unprotected memory is used for messaging and protected memory is used for sharing. A failure in an error containment cluster would corrupt the memory within that cluster, specifically the protected memory within that cluster and also the unprotected memory used by that cluster to communicate with the other clusters. However, the other clusters could continue to run because their protected memory would be unaffected, and could continue to communicate through the remaining unprotected memory.

International Classification:

G06F 1318

US Classification:

711150

Abstract:

A method and system of maintaining strong ordering in a multiprocessor computer system having a coherent memory. Memory transactions are send from one or more processors to a processor agent. The processor agent sends the transactions to a memory agent via a crossbar switch. The memory agent performs memory coherency operations and sends memory transactions back to the processor agents via the crossbar switch. The crossbar switch, however, may alter the order in which the memory transactions are forwarded to the processor agent. Therefore, the memory agent also sends a timestamp for each memory transaction directly to the processor agent via a dedicated link. An arbitrator within the processor agent receives the timestamps and the memory transactions. Using the timestamps, the arbitrator reorders the memory transactions and sends the transactions to the processors in the order in which the transactions were sent. In addition, the memory agent sends a parity signal with each timestamp.
