20090222530System and Method for Service Discovery in a Computer Network Using Dynamic Proxy and Data Dissemination - A service advertisement delivery system and method is useful in a data processing network. A broadcasting node receives service advertisements describing services offered by service providing network nodes. A datastore in communication with the broadcasting node stores a set of the service advertisements of the service providing network nodes. The broadcasting node broadcasts the set of service advertisements over a broadcast channel to service seeking network nodes receiving the advertisements over the broadcast channel.09-03-2009

20110066819Method and System for Optimizing Live Migration of Persistent Data of Virtual Machine Using Disk I/O Heuristics - Techniques for migrating persistent data of virtual machines between and across data stores are optimized using special tracking data structures and monitoring methods. Special tracking data structures include an incremental change block tracking bitmap that indicate what blocks have been modified during a copy operation. The determination of whether any one block has been modified during the copy operation is based on whether or not the copy operation has progressed past that block. Another special tracking data structure is a Bloom filter, which provides a space-efficient data structure for keeping track of dirtied blocks. In addition, heat-based optimization techniques are applied so that blocks that are frequently updated are filtered and not transferred to the destination data store until the last iteration of the migration process.03-17-2011

20110059113GAB2 AMPLIFICATION IN MELANOMA - Provided herein are methods of detecting or inhibiting melanoma growth based on Gab2 protein expression. Gab2 protein was found to be either amplified and/or overexpressed in melanoma. Gab2 protein expression correlated with clinical melanoma progression and higher levels of expression were seen in metastatic melanomas compared to primary melanoma and melanocytic nevi. Over-expression of Gab2 potentiates, whereas silencing of Gab2 reduces, migration and invasion of melanoma cells. Gab2 mediated hyperactivation of Akt signaling in the absence of growth factors and inhibition of the PI3K-Akt pathway decreased Gab2-mediated tumor cell migration and invasive potential. Gab2 over-expression resulted in enhanced tumor growth and metastatic potential in vivo. These results demonstrate a previously undefined role for Gab2 in melanoma tumor progression and metastasis.03-10-2011

20080309217ORGANIC LIGHT EMITTING DEVICES - A light emitting device comprising an emissive material optically coupled to a device that is constructed and arranged to pass an emission wavelength of the emissive material and eliminate angular dependence of the emission wavelength is provided.12-18-2008
20100328671NEAR FIELD DETECTOR FOR INTEGRATED SURFACE PLASMON RESONANCE BIOSENSOR APPLICATIONS - A near-field surface plasmon detector is provided. The near-field surface plasmon detector includes one or more semiconductor layers that absorb one or more surface plasmons of thin metal films in the vicinity of the semiconductor layer. The surface plasmons are excited by incoming light being emitted from a light emitting source. The metal films are also employed as electrical contacts used to capture photocurrent generated after absorption of surface plasmons by the semiconductor layers.12-30-2010

20090180564DITHERING SCHEME USING MULTIPLE ANTENNAS FOR OFDM SYSTEMS - A ground- or roof-top-based repeater in an OFDM system uses multiple transmission antennas to transmit multiple identical OFDM signals. Dithering is performed by introducing a slight variable-frequency phase offset to all but one of the multiple identical transmitted OFDM signals. The effective overall channel is more dynamic and provides spatial diversity to minimize long periods of fading in fading subchannels of the OFDM signals when the receiver is in a slow moving or stationary situation. To overcome the additional cancellation problem that can occur when two or more of the transmitting antennas are (i) in a line-of-site position with the receiver and (ii) approximately the same distance from the receiver, a delay is deliberately introduced to make the delayed signals appear to be reflected signals. This delay will not negatively impact the OFDM receiver performance as long as the delay is within the guard interval used in the OFDM process.07-16-2009

20090011785OPEN LOOP POWER OFFSET UPDATE - Provided is an feedback mechanism to correct power control information in a broadcast signal that is determined to be incorrect by one or more devices that receive and rely on the broadcast information. A device that receives the incorrect broadcast information can determine a correction and to the information and provide a recommendation to the source of the broadcast information. The source can selectively determine whether to modify the broadcast information based on the recommendation from one or more devices. If the broadcast information is modified, subsequent devices that receive the broadcast information are provided with the modified information. If further changes are needed, the subsequent devices can provide further recommended changes.01-08-2009
