Abstract: A method for screening aptamers by using a microarray microfluidic chip. The screening chip integrates microarray and microfluidic technology to integrate the positive and negative screening process on a microfluidic chip, and obtains aptamers with high affinity after 7 rounds of screening. At the same time, the present invention also discloses specific steps for screening of lactoferrin aptamers, including detailed processes such as chip preparation, positive and negative screening processes, and PCR amplification. The aptamers screened by the method have good specificity and affinity to the target protein. The aptamers are easier to be obtained than the antibody, and can be synthesized rapidly in large quantities in vitro. The preparation method is simpler and faster, so aptamers are expected to be a useful complement to antibody technology in many areas.

Abstract: An apparatus and a method for correcting for signal variations in pixels of a main photoelectric conversion element in a radiation detection apparatus due to focal spot position drifts. Edge reference detectors are positioned next to the main detector, in the fan beam coverage but outside the scan field of view. The signal variations of the edge reference detector pixels under the ant-scatter grid shadow are used to estimate the real-time focal spot movement, which is used to estimate the shadow/signal variation on the main detector pixels that are in the scan field of view.

Abstract: In some embodiments, a first detector generates a first output based on a first probability that an image was inserted in a video. The first detector is trained with a set of known images to detect the set of known images. A second detector generates a second output based on a second probability that an image was inserted in the video. The second detector is used to detect the set of unknown images without training. The method analyzes the first output from the first detector based on the probability of the image existing in the video and the second output from the second detector based on the probability of the image existing in the video to generate a combined score from the first output and the second output. An indication of whether the image is detected in the video is output based on the combined score.
