Abstract: The current innovation pertains to the medical data processing domain and introduces a method for formulating an iNPH prediction model using a new/old stimulus BCI paradigm. The process involves conducting new/old stimulus BCI paradigm experiments on a target population both before and after the Lumbar Tap Test, obtaining electroencephalogram (EEG) signal data. After preprocessing the EEG signal data, the model extracts features related to new and old stimulus event-related potentials before and after the test, specifically focusing on P600 amplitude features. The iNPH prediction model is then trained based on these event-related potential features. This innovation facilitates quantifying cognitive function improvement, aiding physicians in prompt iNPH diagnosis and enabling timely and effective patient treatment.

Abstract: The invention relates to a method for preparing transitional-metal particles (cathode particle precursor) under a co-precipitation reaction. In this method, by feeding different types of anion compositions and/or cation compositions, and adjusting the pH to match with the species, precipitated particles are deposited to form a slurry, colleting the slurry, treating with water, and drying to get a cathode particle precursor. Mixing the cathode particle precursor with a lithium source and calcining to yield core-shell structured cathode active particles. Such cathode active particle can be used to prepare cathode of lithium-ion battery.

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 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.
