    摘要: A pulsed fiber laser oscillator and laser systems incorporating such laser oscillators are presented. The laser oscillator first includes a light generating module which generates optical pulses having an initial spectral profile. A spectrum tailoring module tailors the initial spectral profile of the optical pulses by imposing a phase variation on each optical pulse according to an optimized phase varying function. The optimized phase varying function has one of a rectified sinusoidal shape, a parabolic shape and a rectified parabolic shape. Laser systems incorporating such oscillators may be of a MOPA configuration, and may further include a nonlinear crystal for frequency conversion or a bulk solid-state amplifier.

    摘要: High power optical pulses generating methods and laser oscillators are provided. A light generating module generates seed optical pulses having predetermined optical characteristics. A spectrum tailoring module is then used to tailor the spectral profile of the optical pulses. The spectral tailoring module includes a phase modulator which imposes a time-dependent phase variation on the optical pulses. The activation of the phase modulator is synchronized with the passage of the optical pulse therethough, thereby efficiently reducing the RF power necessary to operate the device.

    摘要: Diphtheria and Pseudomonas infections are very common worldwide. The toxins involved in the pathogenesis of those diseases act by inactivating the elongation factor-2 (EF-2), therefore blocking protein synthesis and leading to cell death. Diphthamide formation on EF-2 is a prerequisite step in the inactivation of EF-2, and Dph proteins have been identified as modulating this process. The present application concerns Dph2 deletion mutant genes and proteins and their uses in vitro and in vivo.

    摘要: A method and apparatus for providing service availability information includes receiving a signal transmitted from a base station. A power level and interference level of the received signal is measured and an estimate of a power level of each potentially available service based on the power level of the received signal and predetermined power offsets associated with each of a plurality of potentially available services is derived. An estimate of a signal-to-interference ratio (SIR) for each potentially available service from the estimate of a power level of each service and the measured interference level and a service availability indicator for each potentially available service by dividing the estimated SIR with a target SIR are calculated. Service availability indicators for each potentially available service are outputted.

    摘要: A mesh network includes a plurality of mesh points (MPs), a central database (DB) and a central controller (CC). The MPs are configured to broadcast quality of service (QoS) information over a wireless medium. Each MP may request QoS information directly from at least one other one of the MPs. The MPs store QoS information in the central DB and are configured to query the central DB QoS information associated with any of the MPs. Thus, QoS information is shared throughout the mesh network, and QoS policies are defined and updated where an MP may co-exist with another MP, an MP may co-exist with systems external to the mesh network, and an MP may co-exist with mesh access points (MAPs).

    摘要: A Radio Resource Management (RRM) module is provided to capture network topology information associated with a wireless communication network. This information is transmitted to a Smart Antenna (SA) module collocated within a network node. The SA module determines the appropriate direction, width and power of beams transmitted in the network. The SA module adjusts the direction, width, and/or power of the beams accordingly. A multi-purpose network node for communicating in a wireless communication network operates in a base station mode. If the node detects a change in the network, it determines whether the change should trigger a change in operating modes. If such a change is desired, the node switches between base station and wireless transmit/receive unit (WTRU) modes. The node continues to operate in a WTRU mode until another mode triggering event occurs. In an alternate embodiment, the multi-purpose node operates in base station and WTRU modes simultaneously.

    摘要: A wireless communication system includes a plurality of wireless transmit/receive units (WTRUs) and an access point (AP). The AP communicates with the WTRUs via an antenna. In one embodiment, the AP configures the antenna to a wide beam configuration that covers a desired service area and transmits a Request-To-Send (RTS) control message. When the AP receives a Clear-To-Send (CTS) control message from one of the WTRUs, the AP determines optimal antenna settings for communication with the one WTRU. The AP configures the antenna to a narrow beam configuration and transmits at least one data packet to the one WTRU. When the AP receives an acknowledgement message indicating that the data packet was successfully received by the WTRU, the AP configures the antenna to the wide beam configuration. In another embodiment, the AP is configured to transmit and receive data packet fragments from the WTRUs and configure the antenna accordingly.
