  • Patent number: 12123039
    Abstract: The disclosure discloses the preparation of thermophilic ?-glucosidase and the application thereof, which belongs to the technical field of genetic engineering and fermentation engineering. The present disclosure heterologously expresses the ?-glucosidase TpBgl3A derived from thermophilic fungus Talaromyces piceae by constructing a recombinant bacteria. The enzyme production of recombinant bacteria can reach 2324 U/mL in a 3.6 L fermenter. The resulting ?-glucosidase TpBgl3A can produce gentioligosaccharides with a high conversion rate using glucose as a substrate at a lower enzyme amount added, which significantly reduces production costs. In the reaction system using glucose and cellobiose as substrates, the conversion rate of gentioligosaccharide reaches 26.2%, which has the potential for industrial production of gentioligosaccharide.

  • Patent number: 11860977
    Abstract: Techniques for performing visual clustering with a hierarchical graph neural network framework including a joint linkage prediction and density estimation graph model are described. Embodiments herein recurrently run the joint linkage prediction and density estimation graph model to generate intermediate clusters in multiple iterations (e.g., until convergence) to obtain a final clustering result. In certain embodiments, for each iteration, the input graph contains nodes that are merged from nodes assigned to intermediate clusters from the previous iteration. By using a small and fixed bandwidth k in each iteration, embodiments herein alleviate the sensitivity to the k selection for different clustering applications. Certain embodiments herein remove the tuning of a different k (e.g., k-bandwidth) for k-nearest neighbor graph construction over different clustering applications.

  • Publication number: 20230316219
    Abstract: Techniques for generating recommendations for redistributing product inventories are disclosed. A product redistribution system applies hierarchal prioritization of product locations to generate a plan for redistributing products among the product locations. A system identified product repositories organized into clusters. A product redistribution plan first redistributes products among repositories within a cluster. Then the system redistributes products between different clusters. A system predicts whether repositories have excess products or product shortages by applying product excess windows and product shortage windows to inventory data. The system predicts supply and demand of a product over a period of time including the product supply window and the product shortage window. The system generates the product redistribution plan based on the predicted product excess predictions and product shortage predictions.
