文冠果壳中总皂苷和总黄酮的抗氧化活性"Antioxidant activity of total saponins and total flavonoids from Xanthoceras sorbifolia Bunge shells"
Published 2024-12-01“…The relationship between antioxidant activity and structure-activity of the compounds extracted from Xanthoceras sorbifolia Bunge shells was analyzed.The results indicated that both total saponins and total flavonoids from Xanthoceras sorbifolia Bunge shells had certain scavenging abilities against these four types of free radicals, with the total flavonoids exhibiting higher scavenging capacities than the total saponins for all tested radicals.The structure-activity relationship analysis indicated that the differences in antioxidant activity between the total saponins and total flavonoids from Xanthoceras sorbifolia Bunge shells were related to their chemical structures.In conclusion, extracting total flavonoids from Xanthoceras sorbifolia Bunge shells and developing them as natural antioxidants can help enhance the comprehensive utilization value of Xanthoceras sorbifolia Bunge shells resources. …”

Semantic segmentation of mix loading at asphalt mixing plant based on improved U-Net
Published 2025-04-01“…Aiming at the existing asphalt mixing plant mixture loading semantic segmentation methods with low Mean Intersection over Union(mIoU) values and slow detection speed, a lightweight network RCS-UNet is proposed for semantic segmentation of asphalt mixing plant mixture loading state.Firstly, residual connections are integrated into the U-Net network to mitigate the gradient vanishing issue, promoting stability during training, enhancing convergence speed, and improving generalization abilities. Secondly, the Coordinate Attention(CA) mechanism is incorporated to boost the perception of positional and channel information, refining feature extraction and enabling a sharper focus on critical regions within the image. …”
