Abstract: A distributed wireless communication system includes multiple access points, each with one or more antennas. The access points do not necessarily have synchronized transmitting and receiving radio frequency oscillators. Approaches to channel estimation between the access points and one or more wireless clients account for the lack of synchronization, and do not necessarily require capabilities at the clients that go beyond required or optional features of standard wireless Ethernet (e.g., 802.11n, 802.11g, or 802.11a), thereby supporting “legacy” clients while supporting high data throughput approaches that provide coherent transmission from the multiple antenna of the access points.

Abstract: In one aspect, a distributed coherent transmission system enables transmissions from separate wireless transmitters with independent frequency or clock references to emulate a system where all the transmitters share a common frequency or clock reference. Differences in frequency and/or phase between transmitters are addressed by suitably precoding signals before modulation at one or more of the transmitters based on a synchronizing transmission from one of the transmitters (e.g., a master transmitter) received at a corresponding receiver sharing the frequency or clock reference with each of the one or more transmitters. Such a distributed coherent transmission system can allow N single-antenna transmitters with independent frequency or clock references to emulate a single N-antenna Multi Input Multi Output (MIMO) transmitter, or implement schemes such as distributed superposition coding or lattice codes that require coherence across separate transmitters.

Abstract: An intelligent traffic redirection system that performs global load balancing can be used in any situation where an end-user requires access to a replicated resource. The method directs end-users to the appropriate replica so that the route to the replica is good from a network standpoint and the replica is not overloaded. The technique preferably uses a Domain Name Service (DNS) to provide IP addresses for the appropriate replica. The most common use is to direct traffic to a mirrored web site.

Abstract: The present disclosure provides methods and compositions for treating coronary tissue damaged as a result of a cardiac disorder such as ischemia, acute myocardial infarction, vulnerable plaques, or reperfusion injury. Specifically, the cardiac disorder is treated using a multivalent molecule that is specific for a marker located, in or near the damaged coronary tissue and a marker located on a target cell (e.g., a stem cell). The multivalent molecule may be administered by intravenous injection, intra-arterial catheter, intramyocardial injection, or implantable device (e.g, stent).

Abstract: A process for conversion of organic wastes into biofertilizers such as soil conditioning agents of fertilizer grade, culture grade and soil grade is provided. Also provided is a process for conversion of organic wastes into material for converting waste water into reusable water. The invention provides methods for conversion of organic solid wastes to biofertilizers and reusable water in the presence of a geophagus earthworm Pheretima elongata culure to produce a variety of valuable soil conditioning products and reusable water.

Abstract: Methods are disclosed for separating hemoglobin from erythrocytes by contacting erythrocytes with a hypotonic buffer solution at a rate sufficient to render the release of hemoglobin from said erythrocytes without significant lysis. The hemoglobin is then separated from the erythrocytes. Methods are also disclosed for purifying hemoglobin solutions of DNA, endotoxins and phospholipids by contacting the hemoglobin solutions with an anion exchange medium.
