  • Publication number: 20250003006
    Abstract: The present disclosure provides use of a transmembrane emp24 domain 8 (TMED8) gene in preparation of a drug and a diagnostic kit for pancreatic cancer, and belongs to the technical field of precision tumor medicine. In the present disclosure, it is found that up-regulating an expression level of the TMED8 gene has significantly inhibited migration and proliferation of pancreatic cancer cells, and then promoted apoptosis of the pancreatic cancer cells; the TMED8 gene is further found to be related to a mitogen-activated protein kinase (MAPK) signaling pathway. Therefore, the TMED8 gene may be used as an effective target for gene diagnosis and treatment of the pancreatic cancer.

  • Publication number: 20240184661
    Abstract: In some embodiments, a method receives a trained model for a prediction network, wherein the trained model was trained based on machine generated input and user generated input being correlated to a plurality of categories. Machine generated input is input into the prediction network. The machine generated input is automatically generated based on an execution of an application. The method correlates the machine generated input to one or more of the plurality of categories using the trained model. A score for a respective category is output based on a confidence of the machine generated input being associated with the category. A category is selected from the plurality of categories based on the respective score of the category. The method outputs a resolution for the machine generated input based on the category. The resolution is determined from user generated input that is associated with the category.

  • Publication number: 20240184855
    Abstract: In some embodiments, a method receives machine generated input and user generated input for training a model of a prediction network. A link between a type of machine generated input and a type of user generated input. A first score that represents a correlation between the type of machine generated input and the type of user generated input is generated. The method analyzes the machine generated input and the user generated input using the model of the prediction network to correlate the machine generated input and the user generated input to a category. A second score associated with a confidence that the machine generated input or the user generated input belongs to the category is output. The method adjusts a parameter of the prediction network based on the first score and the second score.

  • Publication number: 20210387594
    Abstract: The disclosure provides a digital contactless signing system for the flexible tobacco distribution, which comprises a cigarette store, a vehicle system, a vehicle access system, a database, a historical database, a server, an information entry unit, an information transmission unit, a distribution system, a client terminal and a two-dimensional code information unit, wherein the cigarette store is connected with the vehicle access system connected with the vehicle access system. The disclosure changes paper tickets into network electronic tickets, and adopts two-dimension code scanning to complete a confirmation of the tobacco handing-over between a distributor and a customer, thereby effectively saving expenses of the paper tickets. An error rate of the signing system is extremely low and almost close to zero due to changing the paper tickets to the network electronic tickets, and a whole data accuracy is improved for signing for the cigarette materials.
