Publication number: 20090136503Abstract: This invention relates generally to the preparation of TRAIL receptor-binding agents and uses of the same. In particular, the present invention relates to the preparation of anti-TRAIL receptor antibodies which recognize a common antigen determinant (i.e., epitope) shared by TRAIL-R1 and TRAIL-R2 receptors and their use for TRAIL receptor detection and modulation of TRAIL receptor-mediated function. The TRAIL receptor-binding agents are useful to induce apoptosis in human cancer cells. These targets may either express one or both TRAIL-R1 or TRAIL-R2.

Patent number: 7386611Abstract: Apparatus and methods for identifying traffic patterns to web sites based on templates that characterize the arrival of traffic to the web sites are provided. Based on these templates, determinations are made as to which web sites should be co-located so as to optimize resource allocation. Specifically, web sites whose templates are complimentary, i.e. a first web site having a peak in arrival traffic at time t1 and a second web site that has a trough in arrival traffic at time t1, are designated as being candidates for co-location. In addition, the present invention uses the templates identified for the traffic patterns of web sites to determine thresholds for offloading traffic to other servers. These thresholds include a first threshold at which offloading should be performed, a second threshold that takes into consideration the lead time needed to begin offloading, and a third threshold that takes into consideration a lag time needed to stop all offloading of traffic to the other servers.Type: GrantFiled: December 10, 2002Date of Patent: June 10, 2008Assignee: International Business Machines CorporationInventors: Daniel Manuel Dias, Richard Pervin King, Zhen Liu, Mark Steven Squillante, Honghui Xia, Shun-Zheng Yu, Li Zhang

Publication number: 20070278710Abstract: An apparatus and method for degating is provided for separating excess molding material from encapsulated electronic packages while the electronic packages are located in a molding system. At least one holding device is coupled to a mold of the molding system, which is located such that excess molding material is molded onto at least a portion of the holding device during molding. A locking feature on the portion of the holding device locks the excess molding material such that the holding device may hold the excess molding material molded onto it to forcibly separate the excess molding material from the encapsulated electronic packages after molding.Type: ApplicationFiled: May 25, 2007Publication date: December 6, 2007Inventors: See Yap ONG, Si Liang LU, Zheng Yu GAO, Swee Huat LEE

Patent number: 7284035Abstract: The present invention relates to a method and system for providing Web content from pull and push based services running on Web content providers to mobile users. A proxy gateway connects the mobile users to the Web content providers. A prefetching module is used at the proxy gateway to optimize performance of the pull services by reducing average access latency. The average access latency can be reduced by using at least three factors: one related to the frequency of access to the pull content; second, the update cycle of the pull content determined by the Web content providers; and third, the response delay for fetching pull content from the content provider to the proxy gateway. Pull content, such as documents, having the greatest average access latency are sorted and a predetermined number of the documents are prefetched into the cache. Push services are optimized by iteratively estimating a state of each of the mobile users to determine relevant push content to be forward to the mobile user.Type: GrantFiled: April 29, 2005Date of Patent: October 16, 2007Assignee: Princeton UniversityInventors: Shun Zheng Yu, Hisashi Kobayashi
