  • Publication number: 20120263676
    Abstract: The present invention relates to compositions, methods and kits based on the ADAM-mediated cleavage of Her-2. The present invention also relates to treatments for cancer, and in particular, breast cancer, by modulating the ADAM-mediated cleavage of Her-2. Further, the invention relates to compositions, methods and kits based on the surprising synergistic effect between inhibition of Her-2 cleavage by an ADAM and certain cytostatic (e.g., Herceptin) and cytotoxic (e.g., Taxol) compounds in, among other things, inhibiting tumor cell proliferation and inducing cell death. Additionally, the invention relates to novel variants of ADAM15, designated ADAM15 variant 1 and ADAM15 variant 2, now identified and isolated.

  • Patent number: 7218714
    Abstract: This invention discloses a method of calling service among devices in home network, comprising following steps: a service calling party obtains a service handle of the called service by using the characterized information of the service, sends a service calling request information to a called party by using the obtained called service handle; the protocol stack of the called party determines whether or not the called service exists based on the service handle of the called service contained in the request information and whether or not the called service has established a renting relationship with the service calling party after receiving the request information, if not, the flow will be ended; if it is, the called party sends service call response message containing service call result to the service calling party; after receiving the service call response message, the protocol stack of the service calling patty determines whether or not the service exist based on the service handle of the called service inc

  • Publication number: 20060155802
    Abstract: The invention relates to a method allowing dynamically networking among a plurality of devices to share resource. It includes: installing a software of dynamic networking and resource sharing on each of devices to realize dynamic networking and resource sharing. These devices periodically announce information with multicasting. A device serves as node control device, and announces the message of the existence of the device through multicasting, creates a node. A device can find the node by monitoring announcement message from the node. The device which requests to join into the node device registers its service information that can be provided by the device to the node control device. The device which has joined into the node finds the device providing service by indexing the nodal control device, and obtains desired service from the device by sending a service calling information. The method is applied to home backbone network for performing networking in home network.

  • Publication number: 20010049284
    Abstract: A system and method using a simulated annealing algorithm in a cellular satellite communications network to assign frequency slots to cells in the network. The system and method employ a static stage in which certain frequencies in a non-uniform spectrum are assigned to cells depending upon the predicted traffic demand of all cells, and a dynamic stage which re-evaluates the real time traffic demand of the various cells and assigns or de-assigns frequencies on an as needed basis. The system and method thus delivers more frequencies to cells with a higher capacity enabling those cells to take on more traffic.

  • Patent number: 6317077
    Abstract: In a satellite communication system (20), a method (50) and system of locating terrestrial-based user terminals (UTs). A UT (23) is located by a two-tier estimation procedure. Under this procedure, an initial estimate of the UT location is performed based on absolute signal propagation delay and Doppler shift measured from a communication link between a satellite and the UT. A second, refined estimate of the UT location is then performed based on the results of the initial estimate. The second estimate can be a function of the absolute propagation delay and absolute Doppler, as well as differential delay and differential Doppler measured from transmissions from two or more satellites (21-22) to the UT (23).

  • Patent number: 6307503
    Abstract: A system (20) and method (40) for determining a user terminal (23) location on the surface of the earth relies on the signal propagation delay and Doppler shift of radio frequency (RF) transmissions between the user terminal (UT) (23) and a satellite (22). An iterative procedure is employed to improve the accuracy of the location determination. Within the procedure, the position of the UT is estimated based on the propagation delay, Doppler shift, and a spherical approximation of the earth's shape. The radius of the earth at the estimated UT position is adjusted using a predetermined model of the earth's shape, such as an ellipsoid approximation. The adjusted radius value is then used to re-estimate the UT location using the spherical approximation. The iterative procedure continues until the estimated UT location converges to a predetermined accuracy.
