Building façade damage segmentation remains challenging because cracks, peeling, hollow-like areas, stains, and erosion often exhibit weak contrast, irregular boundaries, discontinuous structures, and substantial scale variations under complex surface textures and illumination conditions. To address these challenges, t...

Inverse design of membrane-type acoustic metamaterials (MAMs) for low-frequency sound insulation is challenged by costly sample acquisition, limited interpretability of purely data-driven models, non-unique solutions, and unstable training. This study proposes a small-sample physics-informed neural network (PINN) fra...
