The application belongs to the technical field of biological medical materials, and discloses a polydopamine modified modified nano-graphyne and a preparation method and application thereof. In the method, the polydopamine coating is combined with the nano-graphyne for the first time to construct a GDY@PDA composite system, and the core defects of the blocky graphyne, such as easy agglomeration, poor water solubility and insufficient biocompatibility, are solved. The graphyne-based material is applied to the near-infrared two-region photothermal regulation of neural cell calcium influx for the first time, the calcium ion channel is activated through the local thermal effect of the material, and precise, remote and reversible calcium influx regulation is realized; the limitation that the traditional biocompatibility modification is easy to fall off and difficult to functionalize is broken through, the polydopamine modification makes the material have both photothermal efficiency and biological safety, and the application of the graphyne in the treatment of neural diseases (such as neural cell injury repair) is expanded.

The application discloses a ground-based space target monitoring radar atmospheric refraction error correction method. The ground-based space target monitoring radar atmospheric refraction error correction method comprises the following steps: based on the vertical distribution of atmospheric refraction index and the radar elevation angle measurement value, the signal propagation path is accurately recursively calculated by using the refraction theorem and geometric relationship, the corresponding elevation angle, geocentric angle and target apparent distance of different heights are calculated, and a one-to-one corresponding relationship between the apparent distance and the distance, the elevation angle measurement error is established; then, according to the radar distance measurement value, the radar distance and the elevation angle measurement error are calculated by interpolation, and finally, the distance and the elevation angle measurement error caused by the atmospheric refraction of the space target monitoring radar are corrected. The ground-based space target monitoring radar atmospheric refraction error correction method has higher error calculation precision under the condition of given layer interval, has more stable error correction performance, and can more accurately correct the atmospheric refraction error of the space target monitoring radar.

The application relates to a multi-modal emotion recognition method and system fusing bidirectional attention and self-distillation, first, a bidirectional cross attention mechanism is designed to realize bidirectional interaction of information flow between modes, so that text, speech and video can be mutually corrected to mine deeper complementary clues. Secondly, a self-distillation type double-strategy learning framework is introduced to realize exploration of a global optimal solution through parallel conservative fusion and aggressive fusion paths, and the adaptability and generalization performance of the model in low-labeled data, noisy labeling and cross-domain migration scenarios are enhanced. Finally, a mode contribution balance mechanism is constructed to dynamically estimate the reliability and importance of different modes in different samples, suppress the interference of low-quality modes, and enhance the contribution of high-quality modes, thereby significantly improving the robustness and stability of the model in complex real scenarios. The application improves the fusion efficiency of text, speech and video modal information and the fine-grained emotion recognition precision.

This invention provides a virtual terminal incremental interface rendering system, method, and terminal based on the ISOBUS standard. It first calculates the new hash value of each attribute based on interface object attribute update data extracted from ISOBUS messages, and compares this new hash value with the corresponding attribute hash value cached by the object cache management module to accurately identify the actual changed attributes. Based on this, it determines the update method and generates an update data packet embedding the current version number. Then, considering the visibility of each interface object, user attention, and update frequency, it calculates the rendering priority, combines the target frame rate and rendering time budget, selects the set of objects to be rendered in the current frame, and performs incremental rendering. This invention achieves efficient incremental updates through hash change detection, differential data packet generation, and intelligent rendering scheduling technologies, effectively reducing data transmission volume, improving frame rate, and reducing latency, demonstrating significant performance advantages and broad application prospects.
