Research on Dynamic Optimization and Control Mechanism of Intelligent Photoelectric Lighting in Expressway Tunnel

To address driving safety risks and energy waste caused by significant brightness fluctuations on road surfaces, this study proposes a dynamic optimization and intelligent control method for highway tunnel lighting environments. Through field experiments and data analysis under v...

Remarks on Brauer–Manin Obstruction for Weil Restrictions

Given a finite extension [Formula: see text] of number fields and a smooth quasi-projective variety [Formula: see text] over [Formula: see text], if the abelianization of [Formula: see text] is trivial, we prove that there is a natural identification between Brauer–Manin sets of...

STSFusion: segmentation task-driven spatial-frequency collaborative fusion for infrared and visible images

Infrared and visible image fusion aims to simultaneously preserve the saliency of thermal targets and rich texture details. Most existing methods primarily rely on spatial-domain representations, while the frequency-domain information is not sufficiently explored. Moreover, it re...

A Stacking-Fusion Feature Selection Framework for Cross-Year and Cross-Cultivar Leaf Hyperspectral Rice Yield Estimation

Single-criterion feature selection for hyperspectral crop yield estimation suffers from methodological bias and limited generalisation. This study proposes a stacking-fusion feature selection framework with a ridge-regression meta-learner (STACKING_FUSION) that transfers the stac...

Performance enhancement of perovskite solar cells for energy storage applications: Materials and device engineering

Developing highly stable perovskite solar cells (PSCs) is an important prerequisite for their future use in energy-storage-related applications. However, interfacial degradation driven by ion migration and encapsulation failure under thermal and humid stress remain a major obstac...

Study on the Performance Degradation Mechanism of Low-Light-Level Image Intensifiers in Humid and Hot Environments

To analyze the performance stability of image intensifiers under humid and hot environments, this study systematically investigates the device performance degradation mechanism through a combination of natural exposure tests, humidity variation aging tests, disassembly analysis o...

Performance of a novel double-sided irradiation receiver for next-generation solar power tower systems

In solar power tower systems, conventional cylindrical receivers suffer from severe circumferential temperature non-uniformity and excessive thermal stress due to single-sided irradiation. To address these issues, this study proposes a novel double-sided irradiation receiver conc...

Dual-Mode Responsive Dynamic Afterglow Color in CarbonDots and Carbon Nitride Composite for Advanced Optical Informationand Temperature Sensors

Abstract Responsive dynamic afterglow carbon dot (CD) materials, which can continuously emit light of dynamically varying color after excitation cessation, promise broad applications in advanced information encryption and related fields. However, as most reported CD-based aftergl...

Programmable Bandgap in a Topological Semimetal Enables Zero‐Bias UV/NIR Dual Band Photodetection and Optical Encryption Applications

ABSTRACT The monolithic integration of ultraviolet (UV) and near‐infrared (NIR) photodetection in a single device is fundamentally constrained by the inherent spectral crosstalk and architectural complexity of traditional heterostructures. Herein, we circumvent these limitations...

Tailoring Water-Shielding Electric Double Layer and Hydrophobic Solid Electrolyte Interphase for Parasitic Reaction-Free Zinc Metal Anode

Abstract Aqueous zinc-ion batteries (AZIBs) have attracted considerable interest due to their intrinsic merits, such as excellent safety, affordability, and eco-friendliness. However, the practical deployment is greatly limited by H2O-induced parasitic reactions at the zinc metal...

Self-Resetting Synaptic Device toward Low-Power NeuromorphicVision Systems

Abstract Integrating photodetection and optoelectronic synaptic functions into a single device is critical for neuromorphic vision systems. However, such integration typically relies on continuous external biasing and electrical reset pulses for weight regulation, incurring signi...
