Abstract Realization of remote wearable health monitoring (RWHM) technology for the flexible photodiodes is highly desirable in remote‐sensing healthcare systems used space stations, oceans, and forecasting warning, which demands high external quantum efficiency (EQE) detectivity NIR region. Traditional inorganic photodetectors (PDs) are mechanically rigid expensive while widely reported solution‐processed mixed tin‐lead (MSP) perovskite (PPDs) exhibit a trade‐off between EQE Herein, novel...
Abstract. A historic haze event, characterized by lengthy, large-scale and severe pollution, occurred in the Yangtze River Delta (YRD) of China from 1 to 10 December 2013. This event significantly influenced air quality throughout region, especially urban areas. Aerosol physical, chemical optical properties were measured Shanghai. Sometimes h average particle concentration (e.g., PM2.5) exceeded 600 µg m−3. Inorganic water-soluble ions particles, trace gases aerosol coefficients had a...
The essence of audio-visual segmentation (AVS) lies in locating and delineating sound-emitting objects within a video stream. While Transformer-based methods have shown promise, their handling long-range dependencies struggles due to quadratic computational costs, presenting bottleneck complex scenarios. To overcome this limitation facilitate multi-modal comprehension with linear complexity, we introduce AVS-Mamba, selective state space model address the AVS task. Our framework incorporates...
