Abstract: A large model-based recommendation method includes: determining description information of interested content corresponding to a target user; inputting a content to be recommended, the description information of interested content and current popular search sentences into a large model to generate at least one recommendation card corresponding to the content to be recommended, in which the recommendation card contains a recommendation word associated with the content to be recommended; obtaining a current behavior characteristic of the target user; and in response to the current behavior characteristic satisfying a display condition of the recommendation card, displaying the recommendation card corresponding to at least one content to be recommended.

Abstract: A rapid fermentation method for shrimp paste based on combined strain fortification is provided. Cladosporium Z3 and Enterococcus faecalis X1 were deposited in the Chinese typical culture preservation center under preservation numbers CCTCC NO: M 2022487 and CCTCC NO: M 2022486, respectively. Two strains were employed to ferment the small hairy shrimp in two steps, utilizing each strain's properties, which enabled the fermentation capacity to be maximized to increase the fermentation speed and stabilize the quality. In addition, the pollution of miscellaneous bacteria is inhibited by strain-enhanced fermentation.

Abstract: A method of determining a fusion parameter, a method of recommending an information, a method of training a parameter determination model, an electronic device and a storage medium are provided. The method of determining the fusion parameter includes: inputting a recommendation reference information of a target object into a feature extraction network in a parameter determination model to extract a first object feature for the target object; and inputting the first object feature into a multi-task network in the parameter determination model to obtain a first fusion parameter of a plurality of evaluation indexes for the target object. The plurality of evaluation indexes are used to evaluate a preference of the target object for a recommendation information.

Abstract: A modified interleukin-2 (IL-2) molecule is obtained by being subjected to a modification as follows: substituting a region in an IL-2 molecule that mediates the binding of the IL-2 molecule to interleukin-2 receptor alpha (IL2R?) with a region in an interleukin-15 (IL-15) molecule that mediates the binding of the IL-15 molecule to interleukin-15 receptor alpha (IL15R?). The region in the IL-15 molecule that mediates the binding of the IL-15 molecule to the IL15R? includes 9 or more amino acid residues. Furthermore, a protein heterodimer including the modified IL-2 molecule and IL15R? (a Sushi domain) or a variant thereof is provided. The modified IL-2 molecule and/or the protein heterodimer including the modified IL-2 significantly reduce(s) an affinity of IL2R? to greatly reduce its side effects in clinical treatment and is promising drug candidate.

Abstract: By introducing at least one cysteine residue based on wild-type IL-2, the binding plane of the IL-2 derivative and ? receptor subunit is partially or completely blocked, while the affinity of the IL-2 derivative to the complex of ? and ? receptor subunits is basically retained. A complex includes an IL-2 derivative, which is introduced with a third cysteine residue based on wild-type IL-2; and a blocking module, which has or is introduced with a fourth cysteine residue. The third cysteine residue on the IL-2 derivative and the fourth cysteine residue on the blocking module are capable of forming an intermolecular disulfide bond, thereby forming a complex of the IL-2 derivative and the blocking module. The binding plane of the IL-2 derivative and ? receptor subunit is partially or completely blocked, while the affinity of the IL-2 derivative to the complex of ? and ? receptor subunits is basically retained.

Abstract: A decoupling control method for linkage turntable in the technical field of associative motion control mechanisms. Steps of the technical solution are as follows: measure a length L of a hypotenuse of a triangular structure; convert A-axis coordinates input to the system into Z0-axis coordinates according to Z0=L*cos ? and input them on Z0-axis; and in the case of a speed control method, convert the A-axis coordinates into a periodic displacement of Z0 according to ?Z0=L*(cos ?1?cos ?2), and input the displacement to Z0-axis. The beneficial effect is that the horizontal displacement generated by the movement of the Z0-axis is directly integrated into the closed loop of the X-axis by means of measurement combination and the displacement directly calculated by grating scale has high precision and no delay, and it is possible to achieve a more effective control level on this mechanical structure.
