摘要： The present invention provides peptide-based peroxidase inhibitors having the formula AA1-AA2-AA3, wherein AA1 is a positively charged, negatively charged or neutral amino acid, AA2 is a redox active amino acid, and AA3 is an amino acid possessing a reducing potential such that AA3 is capable of undergoing a redox reaction with a radical of amino acid AA2 or a retro or retro-inverso analog thereof. The result of such a combination is a highly effective inhibitor of peroxidase activity that has potent anti-inflammatory properties in widely diverse models of vascular disease and injury. Exemplary tripeptides effectively inhibit peroxidase mediated LDL oxidation, increase vasodilation in SCD mice, inhibit eosinophil infiltration and collagen deposition in asthma mice, inhibit acute lung injury, and decrease ischemic injury of the heart.

摘要： Aspects are described for reducing interference in wireless systems. In a first embodiment, an uplink acknowledgment region associated with a macro cell is determined, and an assignment of uplink control resources is restricted to a region within the uplink acknowledgment region. A control signal is then transmitted to user equipment via the assignment of uplink control resources. In another embodiment, control signals are received from wireless terminals, which include desired uplink control signals associated with an access point base station, as well as interfering uplink acknowledgement signals associated with macro cells. The control signals may then be regenerated by cancelling the set of interfering signals from the control signals. The desired uplink control signals are then decoded.

摘要： A method for a wireless communication includes receiving or storing a peak to average (PAR) back off value; and applying the PAR back off value to determine the transmission power and rate for SIMO and MIMO transmissions. In one aspect, the PAR back off value is at least partially based on modulation type. In another aspect, the PAR back off value is more for higher order QAM than for QPSK. The power allocation algorithm for different UL MIMO schemes is described as follows. For MIMO without antenna permutation (e.g. per antenna rate control), different PAR back off values are considered for different data streams. For MIMO with antenna permutation or other unitary transformation such as virtual antenna mapping or precoding, the PAR back off are determined based on combined channel. The transmission data rate depends on power and also the receiver algorithms such as a MMSE receiver or MMSE-SIC receiver.

摘要： The present invention provides a method and device for allocating uplink shared channel resource, and a communication system, for solving the problem of the overall performance of the communication system being reduced in an existing allocating method. The method comprises: acquiring the volume of data-to-be-transmitted and an uplink channel quality indication; on the basis of the volume of data-to-be-transmitted acquired, determining at least one set of resource profile of the uplink channel quality indication and a resource number; judging of whether or not the uplink channel quality indication comprised within the at least one set of resource profile is identical to the uplink channel quality indication acquired, if identical, using a corresponding set of resource profile as a final resource profile; and if different, combining an uplink transmission power with the corresponding set of resource profile to determine the final resource profile. Under the premise of ensuring QoS, the present invention allows for minimization of transmission power of each terminal, thus reducing inter-system interference, allowing system performance to be further improved.

摘要： Methods, apparatuses, and computer program products are disclosed for facilitating decoding a communication received from a wireless terminal. Encoded bits are received from the wireless terminal via a shared uplink channel, and a plurality of acknowledgment tones are identified within the encoded bits. A correlation value is ascertained corresponding to a correlation between detected bits within the plurality of acknowledgment tones and valid bits corresponding to any of a plurality of valid acknowledgment codewords. A determination is then made as to whether the plurality of acknowledgment tones includes information corresponding to a discontinuous transmission by comparing the correlation value to a threshold value.

摘要： The concept-structured image search technique described herein pertains to a technique for enabling a user to indicate their semantic intention and then retrieve and rank images from a database or other image set according to this intention. The concept-structured image search technique described herein includes a new interface for image search. With this interface, a user can freely type several key textual words in arbitrary positions on a blank image, and also describe a region for each keyword that indicates its influence scope, which is called concept structure herein. The concept-structured image search technique will return and rank images that are in accordance with the concept structure indicated by the user. One embodiment of the technique can be used to create a synthesized image without actually using the synthesized image to perform a search of an image set.

摘要： Techniques for sending control information in a wireless communication system are described. In an aspect, a user equipment (UE) may send data for control information in a resource block with frequency division multiplexing (FDM) and may send pilot in the resource block with frequency-domain code division multiplexing (CDM). The UE may determine multiple groups of subcarriers to use to send data in multiple symbol periods of the resource block based on a predetermined pattern or a pseudo-random hopping pattern. Each group may include consecutive subcarriers to support localized FDM. The multiple groups may include different subcarriers to provide frequency diversity and possibly interference averaging. The UE may send modulation symbols for data (e.g., in the time domain) on the multiple groups of subcarriers in the multiple symbol periods. The UE may send a reference signal sequence for pilot on multiple subcarriers in each symbol period for pilot.
