Hardware implementation of photonic neuromorphic autonomous navigation

Reinforcement learning enables artificial intelligence to move beyond perception toward decision-making, but its deployment on conventional electronic hardware is limited by the latency and energy consumption of the von Neumann architecture. Here, we propose a photonic spiking tw...

Heterogeneous SNN-ANN Multimodal Fusion Framework for Comprehensive Fruit Quality Assessment

Reliable fruit quality assessment is crucial for ensuring food safety and value in modern agriculture. However, many current approaches still rely heavily on visual cues, making it difficult to assess internal quality indicators such as sweetness or internal decay. To address thi...

Designing Efficient Inverted Perovskite Solar Cells with Self-Assembled Monolayer Hole Transport Layers

Self-assembled monolayers (SAMs) have emerged as highly versatile interfacial materials in perovskite solar cells (PSCs), offering tunable molecular structures, favorable energy-level alignment, high optical transparency, and minimized non-radiative recombination losses. With the...

A Fully Biodegradable Hybrid Nanogenerator with Mo Nanoparticle-Mediated Dielectric Enhancement for Improved In Vivo Energy Harvesting

Abstract Implantable medical devices that fully degrade in the body eliminate the need for removal surgeries, yet powering them transiently remains a challenge due to low energy harvesting efficiency. Here, we introduce a fully biodegradable hybrid nanogenerator (FB-HNG) with dra...

UniRec: Unified Space Learning for Generalizable Sequential Recommendation

Sequential recommendation aims to predict users’ next items of interest based on their historical interactions. Recently, Large Language Models (LLMs) have shown strong potential in this field due to their powerful semantic understanding. However, existing methods face two core c...

GSANet: Geometric Structure-Aware Siamese Network for 3D Change Detection

Three-dimensional (3D) point cloud change detection is essential for urban monitoring and environmental analysis, yet existing methods mainly rely on point-wise semantic differences and overlook change–unchange boundaries and object edges—key geometric cues for precise localizati...

taVNS for uterine contraction pain and early recovery after spontaneous vaginal birth: a three-arm randomized controlled trial protocol

Uterine contraction pain after spontaneous vaginal birth (SVB) hinders early maternal recovery. Transcutaneous auricular vagus nerve stimulation (taVNS), as a safe, and non-invasive alternative therapy, can alleviate pain and improve sleep and emotion. Although a recent trial has...

Exploring Marine Atmospheric Ducts: Current Sensing and Emerging Trends

Tropospheric refraction significantly impacts the propagation of ultrashort- and microwave-frequency radio waves over marine environments. Atmospheric ducting, the most common super-refractive structure, allows radio waves to travel over the horizon. This holds significant practi...
