  • Patent number: 9544128
    Abstract: A method of data-aided timing recovery for Ethernet systems is disclosed. A first device negotiates a pseudorandom number sequence with a second device and receives a data signal from the second device. The first device samples the received data signal to recover a first training sequence. The first device also generates a second training sequence based on the pseudorandom number sequence. The second training sequence is then synchronized with the first training sequence. The synchronized second training sequence is used to align a receive clock signal of the first device with the data signal received from the second device.

  • Publication number: 20140134635
    Abstract: The invention is directed to a method of characterizing a mechanism of action of an agent (e.g., a chemotherapeutic agent, a genotoxic agent). The method comprises contacting a plurality of populations of cells with an agent to be assessed, wherein each population of cells have one gene of interest targeted by a small hairpin RNA (shRNA) and wherein said gene of interest regulates cell death and a plurality of genes that regulate cell death are targeted in the plurality of populations of cells. A responsiveness of each population of cells to the agent is determined, thereby obtaining an shRNA signature of the agent, so as to identify one or more genes that mediate a response to the agent, thereby characterizing the mechanism of action of the agent. The invention is also directed an article of manufacture for characterizing a mechanism of action of a chemotherapeutic or genotoxic agent.

  • Patent number: 8669523
    Abstract: One embodiment relates to a method of inspecting a site location on a target substrate. Contours are obtained, the contours having been generated from a reference image using a design clip. A target image of the site location is acquired. The contours are aligned to the target image, and contrast values are computed for pixels on the contours. A threshold is applied to the contrast values to determine contour-based defect blobs. Another embodiment relates to a method of generating contours for use in inspecting a site location for defects. Other embodiments, aspects and features are also disclosed.
