SDFNet: Semantic Driven Frequency-Domain Infrared and Visible Image Fusion Network

Infrared and visible image fusion aims to integrate complementary thermal target information and visible structural details for multimodal perception and remote sensing applications. However, existing deep learning methods often underutilize semantic information during fusion and...

Metasurface-Enhanced Sensing Platforms for Chemical, Biological, and Environmental Monitoring: Recent Advances and Future Perspectives

The growing demand for sensitive, selective, and rapid detection of trace analytes in complex matrices is driving the development of compact optical sensing platforms. Metasurfaces can strengthen light–matter interactions through subwavelength field confinement and resonance engi...

MIMAS: An open-source microlens-array miniature microscope for accessible large-field cortical imaging in freely behaving mice

Large-scale cortical dynamics during natural behavior are difficult to measure because head-mounted imaging systems must balance field of view, spatial resolution, weight, and optical complexity. Existing wide-field miniature microscopes often rely on compound or custom-corrected...

Manufacturable topology optimization for thin-walled cross-sectional design

Thin-walled cross-sections are widely used in lightweight engineering structures because of their excellent stiffness-to-weight and torsional resistance characteristics. However, topology optimization of thin-walled cross-sections remains challenging because conventional density-...

RL-Axial: Learning When to Compute Global Context for Multimodal Segmentation

High-resolution remote sensing semantic segmentation is a key enabler for fine-grained urban mapping and related geospatial applications. However, complex textures, severe scale variations, and cross-modal discrepancies make models with fixed architectures and computation paths s...

DS-PRNet: lightweight camouflaged object detection with dynamic sparse attention and feature-, attention-, and output-level distillation
