Toward high-efficiency photovoltaic energy harvesting: experimental validation of continuous, hybrid, and sensorless dual-axis tracking systems with fixed-tilt solar system

Solar tracking systems have gained considerable attention due to their potential to increase the energy yield of photovoltaic (PV) systems by maintaining the PV module at a favorable orientation relative to the Sun. However, conventional dual-axis trackers often rely on high-powe...

LM-CAGF: A prompt-enhanced Cross-Attention and Gated Fusion framework for multimodal fake news detection

Background and Aim: The rapid proliferation of misinformation, particularly fake news on social media, poses a critical challenge to information credibility and public trust. However, existing fake news detection methods face two major limitations: they often rely on lightweight...

Adaptive learning behavior recognition using multimodal transformer based dynamic modality regulation

Abstract With multimodal interaction becoming increasingly common in intelligent learning systems, behavior streams from clicks, speech, facial expressions, and gestures often show time-varying reliability, short high-saliency events, and correlated or nested labels. These charac...

Dual‐Function Enhancement of PVDF Nanofibers via Bimetallic MOF for Wearable Pressure Sensor and AI‐Driven Non‐Invasive Blood Pressure Prediction

ABSTRACT Engineering high‐performance wearable piezoelectric sensors requires concurrent optimization of β‐phase crystallinity and conductive pathways, a persistent materials‐level challenge. Here, we introduce a novel two‐stage amplification strategy employing a Zn/Cu bimetallic...

HSAR-DETR: Hierarchical Spatial–Frequency Attention Network for UAV Small Object Detection

Small object detection in UAV remote sensing imagery plays a crucial role in applications such as infrastructure inspection, disaster assessment, and precision agriculture, where targets of interest frequently occupy fewer than 32×32 pixels under large ground sampling distance va...

Manifold Regularized Nuclear Norm Matrix Group Sparse Classifier for Robust Image Classification

ABSTRACT Robust representation‐based image classification must cope with complex mixed degradations, including global structural variations (e.g., severe non‐linear illumination) and localized contiguous corruptions (e.g., block occlusions or disguises). While existing matrix‐bas...

Where tourism divides: economic prosperity and disparity in the Kalash Valley

Challenging the assumption that religious minorities are uniformly disadvantaged, this study examines how ethnic tourism in Pakistan’s Kalash Valley is associated with internally stratified livelihood opportunities and household living standards. Guided by Van den Berghe’s theory...

Role-based multi-robot warehouse coordination with reinforcement learning assisted task selection

We study decentralised coordination in large-scale RMFS, where capacity-limited fleets fulfil orders under stochastic demand, congestion, and real-time constraints. We formalise this problem as a role-structured decentralised partially observable Semi-Markov decision process that...
