    • An antenna-receiver communications system and method is provided to mechanize multibeam mobile antenna-receive subsystems. Digital beam forming for modern wideband mobile communications systems is provided. In an aspect, subsystems can simultaneously receive, acquire, track and output a multiplicity of signals from sources of different locations using a single antenna aperture from a mobile platform. The angle of arrival of a signal of interest is continuously determined. Individual phased array antenna output channels are phased aligned as required by the phased array equation and monopulse signal processing. Angle sensing and beamsteering are separated from antenna channel coherent summation. Thus, the angle sensing and beamsteering functions are not required to be computed at the data rate, but can instead be computed at a rate necessary for the beam acquisition and beam tracking function speed requirements. Signal processing computational load and system cost is reduced as compared to current systems.
    • 提供天线接收机通信系统和方法来机械化多波束移动天线接收子系统。 提供了现代宽带移动通信系统的数字波束形成。 在一个方面,子系统可以使用来自移动平台的单个天线孔,同时从不同位置的来源接收,获取,跟踪和输出多个信号。 连续确定感兴趣信号的到达角度。 单相相控阵天线输出通道根据相控阵方程和单脉冲信号处理的要求进行相位对准。 角度感测和波束导向与天线信道相干相加分离。 因此,角度感测和波束导向功能不需要以数据速率计算,而是可以以波束采集和波束跟踪功能速度要求所需的速率来计算。 与现有系统相比,信号处理计算负荷和系统成本降低。

    • The present invention relates to an action between an inhibitor of apoptosis (IAP) protein and members of the caspase family of cell death proteases, for example, an interaction of the X chromosome linked IAP (XIAP) and caspase-3, caspase-7 or caspase-9, wherein the IAP regulates the activity of the caspases. The invention provides screening assays for identifying agents that alter the specific association of an IAP such as XIAP, c-IAP-1 or c-IAP-2 and a caspase such as caspase-3 or caspase-7. The invention also provides screening assays for identifying agents that alter the specific association of an IAP such as XIAP, c-IAP-1 or c-IAP-2 and a pro-caspase such as pro-caspase-9. In addition, the invention also provides methods for identifying agents that modulate the activity of a caspase in the presence of an IAP and that regulate the activation of a pro-caspase by an IAP. The invention further provides methods of reducing the severity of a pathologic condition in an individual by administering to the individual an agent that alters the caspase inhibitory activity of an IAP. In addition, the invention provides methods of modulating the ability of a population of cells to survive ex vivo by contacting the cells with an agent that alters the caspase inhibitory activity of an IAP in the cells.

    • The present invention provides mammalian protein tyrosine phosphatases, human PTP-BAS type 4, human PTP-BAS type 5a and mouse PTP-BAS type 5b, each of which is a Fas-associated protein (FAP), nucleic acid molecules encoding a PTP-BAS type 4 or a PTP-BAS type 5 and antibodies specific for a PTP-BAS type 4 or for a PTP-BAS type 5. The invention also provides methods for identifying FAP's, which can associate with Fas and can modulate apoptosis. The invention also provides screening assays for identifying an agent that can effectively alter the association of a FAP with Fas and, therefore, can increase or decrease the level of apoptosis in a cell. The invention further provides methods of modulating apoptosis in a cell by introducing into the cell a nucleic acid molecule encoding a PTP-BAS or an antisense nucleotide sequence, which is complementary to a portion of a nucleic acid molecule encoding a PTP-BAS. The invention also provides a method of using a reagent that can specifically bind to a FAP to diagnose a pathology that is characterized by an increased or decreased level of apoptosis in a cell. The invention also provides methods of modulating apoptosis in a cell by contacting the cell with an agent that effectively alters the association of a FAP and Fas in a cell or alters the activity of a FAP in a cell.
