Publication number: 20240132925Abstract: The invention provides a method for preparing pyrrolidone, and the invention provides a method for catalytically preparing pyrrolidone with ?-aminobutyric acid in the presence of carnitine-CoA ligase CaiC. The carnitine-CoA ligase CaiC has an amino acid sequence as shown in SEQ ID NO:1. The ligase has catalytic activity in the cyclization of ?-aminobutyric acid to produce pyrrolidone. The carnitine-CoA ligase provided in the present invention affords a yield of pyrrolidone of 3.26 g/L and a molar yield of 39.53% in 24 h when ?-aminobutyric acid is used as a substrate, thus reducing the production period, improving the production of pyrrolidone, and accelerating the industrialization process of producing pyrrolidone by enzymatic conversion method.Type: ApplicationFiled: October 18, 2022Publication date: April 25, 2024Inventors: Jing WU, Xuling JIANG, Liming LIU, Wei SONG, Yiwen ZHOU, Xiulai CHEN, LIU Jia, Cong GAO

Publication number: 20240046920Abstract: A data processing method, a device wake-up method, an electronic device, and a storage medium are provided. In the data processing method, speech to be processed is converted into a keyword phone sequence, and a similar pronunciation sequence generator acquires a similar phone sequence corresponding to the keyword phone sequence in a sequence generation manner, thereby acquiring a first data processed result corresponding to the speech to be processed. By replacing the search method of large-scale speech databases with this generation manner, effective coverage of possible real-life sounds can be achieved with a smaller model, thus improving the ability to distinguish confusing pronunciations. The above data processing method performed by the electronic device can be performed by an artificial intelligence (AI) model.Type: ApplicationFiled: September 25, 2023Publication date: February 8, 2024Inventors: Xiaoyan LOU, Fan ZHANG, Xiangfeng MENG, Liming SONG

Patent number: 11701737Abstract: The disclosed wall includes several narrow aluminum sheets and posts that are Friction Stir Welded (FSW) into a sidewall. The length of the wall is the summation of the narrow sheets' width, and the walls width is the narrow sheets' length. Several aluminum posts are spaced along the wall's length direction in order to improve the stiffness and strength of the wall. When welding the aluminum sheets and posts together, the sheets are placed under the posts and jointed tightly together through FSW. With the high-speed spinning of the stirring pin, the post and sheet melt and form into a compact solid phase weld seam under the extrusion of the welding head. When welding two aluminum sheets and one post together, the two sheets are placed edge-to-edge or slightly overlapped. The post is then placed over the sheet joint and the stir-welding head melts portions of the post and the two sheets simultaneously.Type: GrantFiled: September 10, 2019Date of Patent: July 18, 2023Assignees: Qingdao CIMC Reefer Trailer Co., Ltd., CIMC Vehicles (Group) Co., Ltd.Inventors: Xiaoyi Wang, Niancheng Zhou, Liming Song

Patent number: 11105018Abstract: A process and apparatus for producing a dimensionally stable melt blown nonwoven fibrous web. The process includes forming a multiplicity of melt blown fibers by passing a molten stream including molecules of at least one thermoplastic semi-crystalline (co)polymer through at least one orifice of a melt-blowing die, subjecting at least a portion of the melt blown fibers to a controlled in-flight heat treatment operation at a temperature below a melting temperature of the at least one thermoplastic semi-crystalline (co)polymer immediately upon exiting from the at least one orifice, and collecting at least some of the melt blown fibers subjected to the controlled in-flight heat treatment operation on a collector to form a non-woven fibrous structure.
