  • Publication number: 20250178983
    Abstract: The present invention discloses a complexing agent for promoting decomposition of loquat leaf litter, which belongs to the technical field of plant science. According to the present invention, the mixed solution of Pseudomonas solution, lignin peroxidase, and leucine aminopeptidase solution is applied to the loquat leaf litter, and after in-situ decomposition for four months, the mass loss rate and the decomposition constant of the loquat leaf litter are significantly increased, thereby effectively promoting the decomposition of the loquat leaf litter. The present invention first proposes that the decomposition of the loquat leaf litter is influenced by externally applying a combination agent of enzyme and bacterial solution, which is simple in operation, and promotes the decomposition of the loquat leaf litter while increasing the speed of returning organic matters to soil, thereby improving soil fertility.

  • Patent number: 12288313
    Abstract: Systems and techniques provide for low-latency, full-frequency noise filtering of images through the use of an image-scaling-based filtering technique, or “multiscale filtering technique”, that can provide filtering for low, medium, and/or high frequencies for one or more components of an image, such that the different resolution scales at each level of the multiscale filtering technique provides a larger receptive field for a denoising process employed at each level than a conventional denoising framework. This multiscale filtering includes receiving an input image to be filtered and then performing a multiscale filtering process in which an input image is, at different resolution scales, denoised, downscaled, upscaled, and fused with a result of a lower resolution scale, to generate a filtered image. This may include temporarily buffering intermediate image data for some of the resolution scales at a memory using direct memory access (DMA) operations.

  • Publication number: 20240232292
    Abstract: The general problem of pattern change discovery between high-dimensional data sets is addressed by considering the notion of the principal angles between the subspaces is introduced to measure the subspace difference between two high-dimensional data sets. Current methods either mainly focus on magnitude change detection of low-dimensional data sets or are under supervised frameworks. Principal angles bear a property to isolate subspace change from the magnitude change. To address the challenge of directly computing the principal angles, matrix factorization is used to serve as a statistical framework and develop the principle of the dominant subspace mapping to transfer the principal angle based detection to a matrix factorization problem. Matrix factorization can be naturally embedded into the likelihood ratio test based on the linear models. The method may be unsupervised and addresses the statistical significance of the pattern changes between high-dimensional data sets.
