Adaptive estimation method for pavement adhesion coefficient integrating visual and dynamic data

The road adhesion coefficient is widely recognized as a key factor affecting vehicle active safety control. Accurate estimation of this parameter faces challenges such as visual interference and weak observability of vehicle dynamics under low excitation conditions. This paper pr...

The Impact of 2D Dashboard Spatial Orientation on Gestural Interaction Performance and Ergonomic Concerns in Virtual Reality

Default vertical dashboard orientations in virtual reality (VR) lack systematic ergonomic validation across mainstream gestural interaction paradigms. This study compares four dashboard orientations (horizontal, 60° inclined upward, vertical, 60° inclined downward) under direct h...

Evo-TGSF: an evolutionary topology-genomic subspace fusion framework for Alzheimer’s disease classification using imaging-genomics data

<title>Abstract</title> Brain imaging genomics offers a powerful paradigm for unraveling the complex pathophysiological mechanisms underlying Alzheimer’s disease (AD). However, effective integration of high-dimensional functional magnetic resonance imaging (fMRI) data and single...

Mechanistic Insights into Enhanced Combustion of aGAP-Coated Boron Nanoparticle

Abstract Boron nanoparticles hold great potential for applications in high-energy fuels, but their practical use suffers from limited combustion performance. Glycidyl azide polymer (GAP) is a promising coating material for boron that can improve its ignition and combustion charac...

Alzheimer’s Disease Detection Using Combined EEG Source Connectivity and Microstate Features

Background/Objectives: Electroencephalography (EEG) connectivity and microstate analysis have shown great potential for Alzheimer’s disease (AD) diagnosis; however, their clinical application remains limited by the low spatial resolution of EEG and the lack of standardized micros...

Contrastive Learning Network based on Multi-Scale Transformer (CLMT-net): EEG decoding for fine-grained motor imagery of movements within the same limb

Motor imagery (MI)-based brain-computer interfaces (BCIs) decode EEG signals into control commands. However, fine-grained MI decoding within the same limb remains challenging due to highly similar neural patterns. This paper proposes a Contrastive Learning Network based on a Mult...

Unipolar Barrier Near‐Infrared 2D Photodetectors for 3D Image Sensors

ABSTRACT Photodetectors sensitive to the near‐infrared (NIR) range are of great importance for applications in machine vision, autonomous driving, and three‐dimensional (3D) imaging under low‐light or adverse weather conditions. Recently, two‐dimensional (2D) semiconductors have...

Satellite–Argo Reconstruction of the Mesoscale-Eddy Sound-Speed Field and Its Effect on Towed-Array Gain: A Differentiable Framework with Bounded Acoustic Feedback

We reconstruct the four-dimensional sound-speed field of mesoscale eddies from satellite sea-level anomaly and sparse Argo profiles with a geostrophically constrained coordinate network, and connect it to array-level acoustics through a differentiable parabolic-equation model and...

DynamicFlame Image Generation for Ammonia CombustionMonitoring Using Trend-Encoded Diffusion Models

Abstract Ammonia is a promising green energy carrier, but ammonia combustion, often accompanied by high NOx emissions, poses a great challenge for real-time monitoring. Although flame image-based soft sensors offer a solution for online NOx estimation, the training of this type o...

Crystallographic Orientation Controls Contact and Spin-Photoresponse in 2D Magnetic Heterostructures

Abstract Two-dimensional ferromagnetic semiconductors such as CrSBr offer exceptional air stability, strong magnetic anisotropy, and rich magneto-optoelectronic coupling, yet inefficient electrical contacts continue to limit carrier injection and spin transport in practical devic...

Pronounced bias-enhanced photocurrent with strong polarization sensitivity in 1T-TiSe2-based photodetectors

We report a 1T-TiSe2-based photodetector with pronounced polarization sensitivity and broadband visible-light photoresponse under low-bias conditions. Using a combined density-functional theory and nonequilibrium Green’s function approach, we calculate the transmission spectra an...

A mechanistic model integrating multi‐source data for operational prediction of rice sheath blight at regional scale

Abstract BACKGROUND Rice sheath blight (RSB) is a destructive disease that causes significant yield losses globally. Accurate regional prediction is critical for sustainable disease management; however, existing models suffer from poor generalizability and limited operational app...

Role of sodium hypophosphite on morphology and corrosion resistance of Ni-P coated Nd-Fe-B

Uniform and dense electroless nickel (EN) was recognized as a promising protective coating for Nd-Fe-B magnets. However, large potential difference between intergranular phase and main phase of Nd-Fe-B made the deposition of EN coating uncontrollable. Sodium hypophosphite was use...
