摘要： Provided are methods and compositions for isolating and detecting rare cells from a biological sample containing other types of cells, particularly including debulking that uses a microfabricated filter for filtering samples. The enriched rare cells can be used in a downstream process such as identification, characterization or growth in culture, or in other ways. Also included is a method of determining tumor aggressiveness or the number or proportion of cancer cells in the enriched sample by detecting telomerase activity, nucleic acid or expression after enrichment of rare cells. Also provided is an efficient, rapid method to specifically remove red and white blood cells from a biological sample containing at least one of the cell types, leading to enrichment of rare target cells including circulating tumor (CTC), stromal, mesenchymal, endothelial, fetal, stem, or non-hematopoietic cells et cetera from a blood sample.

摘要： Systems and methods for visual language modeling for image classification are described. In one aspect the systems and methods model training images corresponding to multiple image categories as matrices of visual words. Visual language models are generated from the matrices. In view of a given image, for example, provided by a user or from the Web, the systems and methods determine an image category corresponding to the given image. This image categorization is accomplished by maximizing the posterior probability of visual words associated with the given image over the visual language models. The image category, or a result corresponding to the image category, is presented to the user.

摘要： Circuits, architectures, systems and methods for facilitating data communications and/or reducing latency in data communications. The architecture includes a clock recovery loop receiving data from a host device and providing a recovered clock signal, a filter circuit receiving recovered clock signal information and providing a control signal that adjusts the transmitter clock in response to recovered clock signal information and the two clock signals, and a transmitter receiving the control signal and transmitting data to a destination device in accordance with the transmitter clock. The circuitry generally includes a clock alignment block receiving first and second periodic signals and providing a control signal in response thereto, a filter for first periodic signal information, and a logic circuit configured to combine the control signal and the filtered information, thereby providing an adjustment signal for the second periodic signal. The systems generally relate to those that include the present architecture and/or circuit. The method generally includes determining a phase difference between first and second periodic signals, one of the periodic signals being recovered from a data stream; adjusting the other periodic signal in response to the phase difference and filtered information from the recovered periodic signal; and transmitting the data stream in accordance with said adjusted periodic signal. The present invention advantageously eliminates a FIFO memory in the data path, thereby reducing transceiver latency and improving system performance.

The present invention provides biochips and other fluidic components and methods of use that allow for the direct analysis of ion transport function or properties using microfabricated structures that can allow for automated detection of ion transport function or properties. These biochips and fluidic components and methods of use thereof are particularly appropriate for automating the detection of ion transport function or properties, particularly for screening purposes.

摘要： An H.F. power amplifier is disclosed having a plurality of branches (10, 11, 12) switched in parallel. Each branch comprises a plurality of amplifier elements (T1, T4) switched in series. Resistors (R2, R5) enable the voltage (U_DS) applied to the amplifier elements (T1, T4) to be set at a fraction of a supply voltage (Ud) applied to the branches (10, 11, 12). Capacitors (C2, C4) are used to adjust the source impedance of the amplifier elements (T2, T4). In order to prevent the gate-drain voltage (U_GD) from exceeding the breakdown voltage of an amplifier element (T1, T4) and damaging the amplifier element (T1, T4), a limiting path (7) is connected according to the invention between the gate terminal (G) and the drain terminal (D) of the amplifier element (T1, T4), the limiting path (7) being switchable between a conducting state and a blocking state depending on the gate-drain voltage (U_GD).
