Abstract: The present disclosure discloses a method for synthesizing quinolones intermediates by a continuous flow reaction. Specifically, according to the method, a microchannel reactor is used, which improves the selectivity and conversion rate of the reaction, and the conversion rate of compound ii is increased to more than 95% and the yield is increased to more than 85%; avoids the use of a solvent such as methanol, and methyl tert-butyl ether, etc., in the intermittent reaction process, which simplifies the post-processing method, shortens the overall operation time from about 24 hours to a few minutes, greatly improving the production efficiency, and realizing the continuity and automation of the whole process; and thus makes the product have high purity and high yield, which is suitable for industrial production.

Abstract: An exemplary sliding window scheduling method and system are disclosed. The exemplary sliding window scheduling method and system can schedule multiple packets in a given scheduling frame with a sliding window scheduling frame. The scheduling operation can be performed using bitmap operators and can achieve a lowest time complexity of O(1) per matching computation and per port using distributed parallelization hardware. The exemplary sliding window scheduling method and system can be performed in the context of a queue-proportional scheduler (QPS) as well as iSLIP. In alternative embodiments, the SW-QPS operation can be performed in a batching window rather than in a sliding window.

Abstract: The present disclosure discloses a method and an apparatus for recognizing an image. A specific implementation of the method comprises: acquiring a to-be-recognized image containing a to-be-recognized object; sending the to-be-recognized image to a server, and receiving identification information of a target object corresponding to the to-be-recognized object returned by the server, obtained by recognizing the to-be-recognized image, and a confidence parameter returned by the server; and determining the identification information of the target object as a recognition result when the confidence parameter is greater than a confidence threshold; or acquiring labeled information associated with the to-be-recognized image from a third-party platform and determining the labeled information as the recognition result when the confidence parameter is smaller than the confidence threshold.

Abstract: The present disclosure provides a photo-taking prompting method and apparatus, an apparatus and a non-volatile computer storage medium. On the one hand, a user's image information is collected while the user finds view, then the user's face posture information is obtained from the image information, then face posture information of a preset photo-taking template is compared with the user's face posture information, and the user is prompted to adjust the face posture according to a comparison result. The technical solutions provided by embodiments of the present disclosure may implement prompting the user's face posture adjustment while the user finds view and thereby implement providing guidance for the user's face posture, and solve the problem in the prior art about failure to perform photo-taking guidance while the user finds view.

Abstract: An electrical connector (200) includes a housing (30) having a number of contact cavities (34) and a number of contacts (20) upwardly inserted respectively into said contact cavities (34). Each of the contacts (20) has a lower section (22) and two upper contact beams (24, 26). The lower section (22) includes a center fixing portion (225), two end fixing portions (224, 226), and two connecting portions (228, 229) connected between the center fixing portion (225) and the two end fixing portions (224, 226). The two upper contact beams (24, 26) respectively extend upwardly from the two connecting portions (228, 229). The two end fixing portions (224, 226) and the center fixing portion (225) are fixed to the housing (30).
