Abstract: The present disclosure discloses a method for detecting single strand breaks (SSBs) in DNA based on the following steps. First, DNA of interest is fragmented with a method that generates 3? ends that cannot be tailed. Second, the available 3? ends of the fragmented DNA corresponding to the pre-existing breaks are tailed. Third, SSBs are captured and their positions are identified genome-wide based on the following steps: (1) the tailed fragments are linearly amplified using a chimeric 5?-DNA-RNA-3? primer; (2) the products of primer extension are tailed at the 3? ends; (3) the desired products are amplified by PCR with oligonucleotides containing Illumina® adaptor sequences complementary to both tails and subjected to next-generation sequencing (NGS); 4) finally, positions of SSBs are revealed through the analysis of sequencing results.

Abstract: Embodiments of the present invention provide a divide-and-conquer algorithm which divides expanded data into a cluster of machines. Each portion of data is used to train logistic classification models in parallel, and then combined at the end of the training phase to create a single ordinal model. The training scheme removes the need for synchronization between the parallel learning algorithms during the training period, making training on large datasets technically feasible without the use of supercomputers or computers with specific processing capabilities. Embodiments of the present invention also provide improved estimation and prediction performance of the model learned compared to the existing techniques for training models with large datasets.

Abstract: An optical apparatus and an augmented reality device are provided. The optical apparatus includes an inner surface. The inner surface includes a predetermined region serving as a curved mirror with a predetermined optical parameter for reflection imaging of a virtual image of a virtual world. The optical apparatus further includes an outer surface. The outer surface and the inner surface are used for refraction imaging of a real image of a real world. The virtual image and the real image are integrated for forming a scene of augmented reality.

Abstract: One example packet processing device includes a buffer, and the packet processing device obtains a to-be-measured packet. In response to determining that occupied storage space in the buffer is less than a preset threshold, the packet processing device reads the to-be-measured information from the buffer, and modifies, based on the to-be-measured information and a first algorithm, a pieces of data in first measurement data corresponding to the to-be-measured packet, where a is a positive integer. In response to determining that occupied storage space in the buffer is greater than or equal to a preset threshold, the packet processing device modifies, based on to-be-measured information and a second algorithm, w pieces of data in second measurement data corresponding to the to-be-measured packet, where w is a positive integer, and w is less than a.
