The present invention provides a test device for shield cutterhead mud cakes taking into account high temperature and high pressure. A double-layer cylindrical test cylinder is sealed at the bottom by a cylindrical cylinder bottom cover (4). The top of the double-layer cylindrical test cylinder is open. A cylindrical inner cylinder top cover (3) is movably arranged at the top opening. An electric-controlled jack (5) for applying vertical pressure is connected to the upper surface of the cylindrical inner cylinder top cover (3). A plurality of electrically controllable heating rods (13), a plurality of unconfined compressive strength sample molds (11) and a plurality of direct shear sample molds (12) are arranged inside the double-layer cylindrical test cylinder. The present invention also discloses a test method for shield cutterhead mud cakes taking into account high temperature and high pressure. The present invention can study the mechanism or conditions of cutterhead mud cakes under the action of high temperature and high pressure, which is more consistent with the actual situation and avoids the operation of injecting a dispersant to decompose the mud cakes after the mud cakes are formed in shield practice.

The application discloses an iPSC reprogramming kit and application thereof, and belongs to the technical field of induced pluripotent stem cells. The kit comprises a combination of small molecule compounds or a combination of multiple culture media, and is used for reprogramming T cells into iPSCs. The compound combination can be used for phased chemical regulation in different stages of Sendai virus infection. The application combines Sendai virus and chemical regulation, and can directly start the reprogramming of T cells from less than 10,000 T cells (such as a tube of micro peripheral blood), without an intermediate expansion step. Meanwhile, the synergistic effect of chemical regulation and Sendai virus can improve the reprogramming efficiency to 5-10 times of that of an existing scheme.

The embodiment of the application provides a lightweight model cloud edge collaborative self-training evolution method for an industrial scene, and belongs to the technical field of intelligent industry. The method forms a lightweight representation of a mutation period in a structured log and a window statistical manner on the edge side, and only returns key samples and key contexts when a trigger condition is met, thereby reducing the return bandwidth and return cost. At the same time, the cloud end cognitive writeback provides weak supervision and enhancement instructions for the mutation samples, so that the lightweight edge model has the feasibility of low-cost self-training. Further, through the hierarchical conflict buffer and dynamic gating mechanism, the noise samples are inhibited from damaging the iteration, and the stability after going online is guaranteed through conflict suppression and stability maintenance constraints. Finally, through the effect association of the new inference log and the backflow package, reusable continuous optimization is formed, so as to realize the reduction of edge inference misjudgment rate and the improvement of inference stability, and the real-time and lightweight deployment constraints are also considered.
