  • Publication number: 20120225063
    Abstract: Methods are provided for selecting and treating patients with an anti-angiogenic agent and methods for reducing the risk of adverse events in patients from treatment with an anti-angiogenic agent, comprising the steps: obtaining a sample of tumor and normal tissues from a patient; determining the miRNA or protein expression in said samples; comparing the miRNA or protein expression in said tumor sample to the miRNA or protein expression in normal tissue; determining whether said tumor miRNA or protein expression is higher or lower than said normal miRNA or protein expression, wherein if said miRNA or protein expression indicates that the expression of at least one angiogenic gene is upregulated, the patient is scheduled for treatment with an anti-angiogenic agent. Preferably the anti-angiogenic agent is a VEGF-targeting agent or a tyrosine kinase inhibitor. In preferred embodiments, the VEGF-targeting agent is bevacizumab.

  • Publication number: 20090326704
    Abstract: Processing a lot through a cluster tool having multiple processing chambers includes dispatching a lot to a cluster tool having a plurality of processing chambers, determining which of the plurality of processing chambers are active processing chambers and inactive processing chambers, setting a recipe for processing the lot utilizing the active processing chambers of the cluster tool, and processing a portion of the lot through the active processing chambers. Processing the lot further requires detecting that at least one of the inactive processing chambers is a re-activated processing chamber, selectively setting a new recipe for processing a remaining portion of the lot utilizing the active processing chambers and the re-activated processing chamber, and processing the remaining portion of the lot through the cluster tool based on the new recipe.

  • Patent number: 4816825
    Abstract: The disclosure depicts in a two-way broadband communications network employing a carrier sense multiple access with collision detection protocol an apparatus and method for controlling station transmit signal levels. Signal level detection circuitry is coupled to one or a plurality of locations in the network transmission medium to determine the signal level generated by each of the plurality of stations periodically transmitting into the medium. The detected signal level from a station is compared to a predetermined range of appropriate values for the station and where the station is transmitting signals outside of the predetermined range, a correction factor is applied to the station to adjust the transmit levels of the station.
