The invention discloses a rapid interlocking type mechanical connection system used between prefabricated floor slabs and a construction method, and belongs to the technical field of prefabricated buildings. The system comprises a plurality of integral composite floor slabs which can be connected with one another, and each integral composite floor slab comprises an integral frame, a filling layer, a pouring layer, distribution steel bars and a connecting assembly. The overall frame is of a space grid structure formed by welding C-shaped steel keels, and the end of the overall frame is provided with a concave-convex complementary tenon-and-mortise imitating connection structure. The filling layer is made of light heat preservation materials, and the pouring layer is made of high-strength light concrete. The connecting assembly comprises a mortise and tenon imitating structure, a caulking component and a screw component, the caulking component has sealing, waterproof and elastic buffering functions, and the screw component achieves bidirectional constraint. And a factory prefabrication and on-site rapid assembly mode is adopted for construction. The connecting structure integrates multiple functions, solves the problems that an existing floor is weak in connection, low in construction efficiency and the like, has the advantages of being reliable in connection, convenient and fast to construct, energy-saving, environment-friendly, wide in application range and the like, and can be widely applied to various prefabricated buildings.

This invention relates to the fields of deep learning and medical imaging. More specifically, it relates to a method for fundus vessel segmentation based on multi-band wavelet decomposition and the Mamba architecture. In response to the acquisition of a fundus image, the fundus image is preprocessed to obtain an input image; the first feature map of the input image is decomposed into low-frequency approximation components and high-frequency detail components; the low-frequency approximation components are input into a low-frequency connectivity enhancement path, and a global topological scan is performed using a selective state-space model to extract long-distance connectivity features of the main vessels; the high-frequency detail components are input into a high-frequency detail refinement path, and a lightweight Mamba module is selectively activated through a sparse gating mechanism to scan and extract edge features of peripheral vessels; unlike existing technologies, this invention effectively solves the problems of existing technologies being unable to differentiate between main vessels and small vessels and struggling to maintain the connectivity of the vascular topology.

The invention relates to the technical field of batteries, in particular to a battery pack bottom support. The battery pack bottom support is used for bearing a battery pack and comprises at least two trays and connecting pieces, a split gap is formed between any two adjacent trays, any tray comprises a frame body, a reinforcing part and a connecting part which are integrally formed, the frame body is used for being connected with a girder of a vehicle, the reinforcing part is arranged in the frame body, and the connecting pieces are arranged on the frame body. Part of the connecting part is arranged on the frame body, the other part of the connecting part is arranged on the reinforcing part, and the connecting parts are used for connecting the battery pack; and the connecting pieces are positioned in the split gaps, are connected with any two adjacent frame bodies, and are used for connecting the battery packs. According to the battery pack bottom support, the at least two split type sub-trays are obtained through integrated die casting, so that the battery pack bottom support can adapt to various vehicle girder specifications, and the mold opening cost is reduced while the structural consistency of the battery pack bottom support is improved.

The utility model relates to the technical field of pipeline connection, and provides a pipe-jacking pipeline connection structure aiming at the conditions that the structural strength of a pipeline connection part in traditional pipe-jacking construction is limited, and the edge is easy to crack and break due to uneven stress or external load action. The two ends of the pipeline body are coaxially connected with a metal annular protrusion and a metal annular groove correspondingly. The periphery of the metal annular protrusion is sleeved with a plurality of flexible sealing rings, and the ends, close to each other, of the adjacent pipeline bodies are matched with the metal annular groove in an inserted mode through the metal annular protrusion. The pipe joint structure has the effect of improving the structural strength of the pipe joint.
