Abstract: The present disclosure discloses an extremely high-temperature in-situ fretting fatigue experimental device for a mortise-tenon joint. The device includes: a loading member configured to support a tenon specimen and a mortise specimen, and apply a fatigue load; a heating member to heat the tenon specimen and the mortise specimen; a thermal insulation sleeve wrapping the heating member; a thermal insulation shield with an observation hole; and a control member configured to control operation of the fatigue loading. Various measures including the using of heat-resistant materials for the gasket, thermal insulation shield and sleeve, reducing and shielding thermal electrons, and decreasing a temperature in non-critical areas are adopted to improve high-temperature imaging quality of an in-situ Scanning Electron Microscope (in-situ SEM) and enhance an upper limit of an in-situ SEM experimental temperature.

Abstract: A digital twin-based intelligent slope monitoring method, system, and storage medium are provided. The method includes obtaining point cloud data of a surface of a slope, creating a digital twin model; dividing the digital twin model to generate a plurality of first grids, calculating a displacement change value of each first grid during a target duration; defining the first grid with a displacement change value greater than a first threshold as a first region, dividing the target duration into a plurality of first durations with different lengths; setting a plurality of rainfall patterns, determining an optimal pattern for each first duration, calculating representative rainfall, constructing a prediction model, predicting representative rainfall for a future duration based on the optimal pattern and the representative rainfall of the first duration; generating a safety factor of the first region during the future duration based on the representative rainfall and a pore water pressure.

Various measures including the using of heat-resistant materials for the gasket, thermal insulation shield and sleeve, reducing and shielding the thermal electrons, and decreasing the temperature in non-critical areas are adopted to improve the high-temperature imaging quality of the in-situ Scanning Electron Microscope (in-situ SEM) and enhance an upper limit of the in-situ SEM experimental temperature.

Abstract: A system for ultra-high temperature in-situ fretting fatigue experiment, includes a heat preservation cover defining a, a heating device arranged in the mounting space, a first test sample, a second test sample, and a clamping device arranged in the mounting space. The first test sample and the second test sample are arranged at an upper end of the heating device along a horizontal direction. A mortise is formed at an end of the first test sample facing towards the second test sample. A tenon mating with the mortise is formed at an end of the second test sample facing towards the first test sample. The clamping device is configured to be clamped at two ends of the mated first test sample and second test sample and to apply a periodically reciprocating loading along a length direction of the first test sample and the second test sample.

Abstract: The present invention relates to a long-circulating liposome modified with c(RGD-ACP-K). The present invention pertains to the field of pharmaceutical preparations, in particular to the field of targeted pharmaceutical preparations. More specifically, the present invention relates to a long-circulating liposome, the surface of the liposome being modified with c(RGD-ACP-K), and the liposome comprising doxorubicin or a pharmaceutically acceptable salt thereof such as doxorubicin hydrochloride as an anti-cancer active agent. The long-circulating liposome can targetedly deliver the anti-cancer active agent into tumor neovascular endothelial cells and tumor cells and can prolong the circulation time of the liposome in vivo, thereby enhancing the therapeutic effect of anti-tumor medicaments.
