The accuracy-safety trade-off of large reasoning models in clinical diagnostics
Abstract Large reasoning models (LRMs) offer potential advantages for clinical diagnosis over standard large language models (LLMs), yet their utility and safety remain unclear.

A Lightweight YOLOv5-Based Model with Feature Fusion and Dilation Convolution for Image Segmentation
4.3. Comparison Experiment This section compares the MDM-YOLOv5s network with other image segmentation algorithms, and from Table 5, we can learn that the improved algorithms in this paper have higher accuracy than other algorithms. From the experimental results in the above table, it can be seen that the MDM-YOLOv5s algorithm is more accurate than U-Net, SegNet, and Mask R-CNN for image segmentation, respectively, and the accuracy curves of each algorithm model are shown in Figure 7.
The inhibition of EZH2 ameliorates osteoarthritis development through the Wnt/β-catenin pathway
To evaluate if there is aberrabt activation of EZH2 in the development of OA, we compared the level of EZH2 in normal and OA human articular chondrocytes by Realtime PCR and Western blotting analysis. HE staining showed smooth surfaces in human articular cartilage and rough surfaces in OA human articular cartilage (Fig. 1A). Furthermore, Real-time PCR analysis revealed higher level of EZH2 mRNA in OA chondrocytes compared to normal chondrocytes (Fig. 1B).
