This utility model belongs to the field of yak disease prevention technology, specifically a yak disease prevention passageway. Addressing the problems of existing yak disease prevention passageways causing congestion and slow isolation during the transfer of suspected sick yaks, as well as limited spray range, incomplete disinfection, and increased risk of disease transmission, this invention proposes the following solution: It includes a main containment area and at least two sub-containment areas. A trapezoidal inspection passageway, wider at the top and narrower at the bottom, is provided between the main and sub-containment areas. Both ends of the inspection passageway connect to a self-propelled passageway. In this utility model, a reasonable passageway is constructed using trapezoidal frames to ensure orderly passage of yaks. Simultaneously, the drive component, in conjunction with the guardrail, allows for the rapid and safe transfer of sick yaks to the isolation area. A cylinder-driven fixing frame stabilizes and restrains the yaks, while the spray nozzles of disinfection pipes I and II achieve comprehensive disinfection. The coordinated operation of all components ensures efficient and continuous disease prevention, weighing, and isolation, reducing manpower and lowering the risk of disease transmission.

This invention discloses a method for expanding the volume of a composite matrix, an osteogenic composition, and its applications. The components of this invention are entirely autologous, posing no risk of immune rejection or disease transmission. The composite matrix in the osteogenic composition provides a bone conduction scaffold, while the volume-expanding agent provides bone-inducing signals while simultaneously expanding the composite matrix, thus providing a dual osteogenic mechanism. This invention requires only a conventional centrifuge and sterile containers, making it suitable for outpatient surgery. It also eliminates the need to purchase expensive bone powder, offering advantages such as ease of operation and low cost. Furthermore, the materials of this invention exhibit good stability; the composite matrix, after being encapsulated by the volume-expanding agent, does not easily dissipate and conforms well to the defect morphology.

The application relates to the technical field of biology, and particularly discloses an artificial synthetic dermis loaded with subacromial synovial mesenchymal stem cell composite patch as well as a preparation method and application thereof. The artificial synthetic dermis loaded with subacromial synovial mesenchymal stem cell composite patch has the advantages of convenient raw material source, no immune rejection, no supply area complications, no disease transmission risk and the like. Moreover, the composite patch provides initial mechanical support, and improves the tendon-bone interface microenvironment through the paracrine effect (including pro-angiogenic related factors) of the subacromial synovial mesenchymal stem cells, promotes host cell infiltration and blood vessel ingrowth, and enhances tissue integration and rotator cuff healing.

This utility model provides a tiger whisker-shaped toothpick, relating to the field of toothpick technology, which solves the problem that existing toothpicks have smooth surfaces, making them inconvenient for removing foreign objects from teeth. The toothpick includes a toothpick assembly comprising a shaft, a head, and a silicone threaded strip. The head is fixedly connected to the bottom of the shaft, and both the shaft and the head are provided with silicone threaded strips. The shaft, head, and silicone threaded strip form a shape resembling tiger whiskers. One side of the silicone threaded strip has an irregular serrated shape. With the help of this toothpick assembly, foreign objects in the gaps between teeth are easily removed, reducing damage to the gums and preventing the possibility of disease transmission.

The application provides an influenza prediction method, system, device and medium based on epidemic dynamics, and relates to the technical field of epidemic transmission prediction, which realizes collaborative modeling of data-driven and mechanism-driven by fusing multiple source monitoring data and epidemic transmission mechanism; in the feature engineering stage, the influenza monitoring data is structured and features are extracted, forming influenza transmission features with physical meaning; in the prediction stage, a physical information neural network model based on a deep neural network framework is used, which includes an input layer, a multi-layer feedforward network, a time embedding representation layer and an output layer, and is trained by fusing an observation data fitting and a composite loss function constrained by the epidemic dynamics mechanism, so that the model can fit the historical monitoring data and strictly follow the internal dynamics law of disease transmission, thereby significantly improving the accuracy, interpretability, extrapolation stability and robustness to small samples and noise interference of the prediction result.
