Shape-memory polyurethane foam integrated with nanofiber technology: synergistic efficacy in reducing the risk of capsular contracture and infection in breast reconstruction applications

Kawun Chung, Lunqiang Jin, Qiang Zhang, Lin Tan et autres

= 11.4 µm), biphasic drug release profile (65.0 ± 4.5% released within 24 hours; 79.9 ± 3.2% by 7 days), excellent shape recovery (>94.5% after cyclic strain), and cytocompatibility (cell viability >80%). Importantly, in an infected breast reconstruction model, PUF-PG-MA resulted in …

Microstructure, mechanical properties and corrosion behavior of high-entropy (WZrNbTaM)C (M= Cr, Ni, Ti) carbides

Jiatai Zhang, Weili Wang, Zhixuan Zhang, Sijie Wei et autres

In this work, the high-entropy stability is predicted based on density functional theory (DFT) firstly. Then, the (WZrNbTaM)C (M=Cr, Ni, Ti) high-entropy carbide powders are synthesized by carbothermal reduction reaction. The synthesized high-entropy carbide powders are densified with addition of Co and …

Gas sensor based on Goos-Hänchen shift in twisted BP/ α -V 2 O 5 metamaterial surface structure

Yining Yan, Song Bai, Rongyang Cui, Wei Huang et autres

Abstract This paper constructs a BP/ α -V 2 O 5 metamaterial structure by stacking a black phosphorus (BP) layer onto a semi-infinite orthorhombic-phase vanadium pentoxide α -V 2 O 5 crystal. By varying the angle between the anisotropy axis of the …

ClinDEF: A Dynamic Evaluation Framework for Large Language Models in Clinical Reasoning

Yuqi Tang, Jing Yu, Zichang Su, Kehua Feng et autres

Clinical diagnosis begins with doctor-patient interaction, during which physicians iteratively gather information, determine examination and refine differential diagnosis through patients' response. This dynamic clinical-reasoning process is poorly represented by existing LLM benchmarks that focus on static question-answering. To mitigate these gaps, recent …

单光子探测技术作为光量子学科方向的重要技术，已经广泛应用在自动驾驶、对地遥感及航空航天等众多领域。三维成像目标常处于运动状态，导致图像帧之间产生结构偏移和配准误差，影响成像清晰度和精度。针对这一问题，提出一种基于自适应扩展卡尔曼滤波的动态单光子三维成像方法，结合图像质量评估结果，对协方差参数自适应调整，并融合图像间匹配特征与时序加权策略，实现目标旋转状态的稳定估计。实验仿真基于生成的单光子三维成像数据进行验证，结果表明所提方法在复杂场景下均能有效恢复目标轮廓与结构细节。与传统方法相比，平均峰值信噪比（peak signal-to-noise ratio，PSNR）提升2.93 dB，结构相似性（structural dissimilarity，SSIM）提升0.115，验证了其在复杂旋转条件下的成像精度与稳健性优势。
