Abstract: The present invention relates to a shelf supporting sliding rail, including a sliding rail body. Protrusions and recessed portions distributed in an array in a length direction are arranged on a front surface of the sliding rail body. The protrusions and the recessed portions are arranged in a spaced manner, and the protrusions are in close connection to the recessed portions adjacent to the protrusions above to form a locking position where a shelf mounting buckle is locked. The depth of the locking position in a direction perpendicular to the front surface of the sliding rail body increases, to improve the locking stability and reliability of the shelf mounting buckle on the shelf supporting sliding rail, and further improve the bearing capacity.

Abstract: Semantic analysis is performed on semantic data of content and/or a service that are/is historically requested by a user, to obtain intent data corresponding to the content/service historically requested by the user. After the intent data and the content and/or the service that are/is historically requested by the user (namely, historical data of the content and/or the service that are/is requested by the user) are fused, fused data is analyzed by using a deep learning algorithm, to obtain intent prediction information of the user. Advance deployment of a network architecture and advance configuration of a network resource are performed based on the intent prediction information of the user, so that the network resource is allocated correctly, properly, and in time, and proper and effective deployment of the network architecture is ensured, thereby improving communication efficiency.

Abstract: A charging pile includes a precharge circuit and at least one power conversion apparatus. An output end of the precharge circuit is connected to a bus capacitor in each power conversion apparatus. Each power conversion apparatus is configured to provide electric energy for a charging connector. When each power conversion apparatus is in an off state and maximum power-off duration is greater than first preset duration, the precharge circuit is configured to output a recovery voltage, so that each bus capacitor is powered on. Power-off duration is an interval between last power-off time and current power-on time of the bus capacitor. The maximum power-off duration is maximum duration in power-off duration of each bus capacitor. The recovery voltage is less than a rated voltage of any bus capacitor.

Abstract: An efficient synthesis and assembly method for the large fragment DNA based on the programmable nuclease Argonaute, specifically includes: constructing and treating antibiotic resistance gene reconstructed vectors with linearization, dividing a target DNA into multiple small DNA fragments and then synthesizing the small DNA fragments, followed by loading the synthesized small DNA fragments to the antibiotic resistance gene reconstructed vectors; and the SLIC and resistance gene reconstruction are used to achieve assembly of the target DNA. The method combines the SLIC with a resistance gene reconstruction strategy, allowing for the assembly of 5-6 small fragments in a single resistance gene reconstruction, which is more efficient and time-saving. Moreover, the number of the resistance gene reconstructions can be flexibly chosen according to the length of the DNA fragments. Mutations are not introduced caused by PCR, and the reconstructed large fragment do not need a second sequencing, saving time and costs.
