  • Patent number: 12345665
    Abstract: A calculation method for fractal dimensions of shale pores includes steps as follows. S1: multiple shale samples from a target stratum of a study area are obtained, parameter values of geological parameters of each of the multiple shale samples are obtained, followed by dividing the multiple shale samples into target shale samples and experimental shale samples. S2: PCA is performed on the parameter values to obtain principal components representing a variation of the geological parameters. fractal dimensions are calculated based on an existing fractal dimension calculation method. S3: the principal components are used as independent variables and the fractal dimensions are used as dependent variables, followed by performing regression analysis to obtain a quantitative calculation model. S4: the fractal dimensions of the target shale sample are calculated according to the parameter values and the quantitative calculation model for the fractal dimension based on the parameter values.

  • Publication number: 20250205329
    Abstract: The present disclosure relates to the field of biomedicine, and in particular, to an improved mutant of a respiratory syncytial virus (RSV) fusion (F) protein and uses thereof. The mutant can form a trimeric structure without introducing a heterologous trimerization domain. Meanwhile, through mutation designs such as releasing internal electrostatic repulsion, deleting the furin cleavage site, truncating the C-terminal domain, and introducing interchain disulfide bonds, the protein is stabilized in the pre-fusion conformation and exhibits enhanced stability. The mutant in the present disclosure is highly immunogenic when used as a vaccine or a vaccine component and can induce the production of a high level of neutralizing antibodies in the immunized animal, which can be used in the preparation of a vaccine for the prevention or treatment of RSV infection, and can also be used as a reagent for the detection of RSV.

  • Patent number: 12337585
    Abstract: A decorative film includes a film body and a decorative layer. The film body is made of a transparent or semi-transparent material. The decorative layer is disposed at the film body and includes a texture layer and/or a semi-transparent colored ink layer, where the texture layer is transparent or semi-transparent. When the light-emitting element emits no light, the texture layer enables the decorative film to present at least one of a pattern effect, a dazzle effect, a matt effect, or a color-change effect, and the semi-transparent colored ink layer enables the decorative film to present the same color as the semi-transparent colored ink layer. When the decorative film is applicable to the light-emitting module, the decorative film covers the light-emitting surface of the light-emitting element, which can not only protect the light-emitting element, but also decorate the light-emitting module in a non-light-emitting state.
