Leakage Signal Denoising of Water Supply Pipelines Based on the Gray Wolf Optimization Algorithm

Abstract To address the issue of suboptimal denoising performance in variational mode decomposition (VMD) due to the reliance on empirical parameter selection, this paper proposes a novel joint denoising method (GVMD) based on the gray wolf optimization (GWO) algorithm for the op...

How Does the Digital Economy Drive County-Level Sustainable Development? A Perspective on the Coordinated Development of Economic and Environmental Resilience

The digital economy is a vital engine driving grassroots sustainable development, yet whether and how it promotes the coordinated evolution of economic and environmental resilience at the county level remains to be further empirically tested. Using panel data for 1399 Chinese cou...

Culinary Chemistry as a Platform for Interfacial Materials Design

ABSTRACT This Review examines culinary systems as experimentally accessible models of interfacial materials design. Culinary operations, including emulsification, foaming, gelation, spherification, controlled heating, smoking, and dehydration, govern gas‐liquid, oil‐water, solid‐...

Digital transformation-driven supply chain resilience and sustainable supply chain performance: an empirical investigation of the fresh agricultural product industry

Purpose The fresh agricultural product supply chain, as a foundational industry critical for safeguarding people’s livelihoods, has increasingly encountered frequent external uncertainties in recent years. These disruptions severely undermine operational stability and precipitate...

Complementary Detection of Zero-Value InsulatorsBased on the Fusion of Infrared Images and ElectricField Intensity Features

To address the electrical safety hazards caused by missing zero-value insulators in high-voltage transmission lines, this study proposes a complementary detection method based on the fusion of infrared images and electric field intensity features. Infrared images of insulator str...

Accurate β-Casein Allergen Quantification in Processed Foods via an Isotope-Labeled Full-Length Protein Internal Standard

Abstract Accurate quantification of cow’s milk allergens in processed foods by UPLC-MS/MS is challenged by enzymatic digestion variability and complex matrix effects. β-Casein, a major milk allergen, requires reliable quantification. Herein, we developed a novel method for quanti...

Reconstruction of soil microbiome and elemental cycling by a synthetic microbial community: A sustainable strategy for improving paddy soil fertility and rice production under agrochemical reduction

Intensive rice cultivation often relies on substantial agrochemical inputs to maintain soil fertility and crop productivity, creating challenges for sustainable paddy management. In the present study, a field trial combined with metagenomic sequencing was performed to uncover the...

Safeguarded online self-training for continual tunnel-face blast-hole detection

Continual full-image blast-hole detection is required as tunnel-face imagery accumulates under weak or unreliable hole-position priors, while hidden batch annotations prevent direct supervision during online updating. This study presents safeguarded online self-training, an artif...

Vibration response of a waterjet propulsion pump under low-gas-fraction microbubble inflow

This study experimentally investigates the vibration attenuation effect of low-inlet-gas-volume-fraction microbubble inflow in a waterjet propulsion pump. Hydraulic performance and triaxial vibration responses at the inlet, impeller, and outlet were measured under IGVF values of...

Performance and issues of consolidation polymers for applications in conservation of outdoor cultural heritage: A review

Outdoor stone cultural heritage is constantly subject to coupled temperature and moisture cycling, salt transport and crystallization, solar radiation, atmospheric chemistry, and biological activity. Under such conditions, the field performance of polymer-based consolidants and p...

Aromaticity Engineering of Hybrid Cyanine Dyes for Metabolic Labeling and Bioorthogonal NIR‐II Imaging of Gut Microbiota

In the context of diabetes, host immune dysfunction and microcirculation damage significantly increase the susceptibility to bacterial infection. Therefore, the development of high-performance molecular imaging tools to dynamically track the migration and colonization of bacteria...

Leveraging explainable artificial intelligence and satellite time-series for unravelling nonlinear environmental drivers of post-wildfire vegetation recovery

Understanding post-wildfire vegetation recovery is critical for ecological restoration under climate change. Using the severe March 2024 Yajiang forest fire in China's alpine ecosystem as a case study, we integrated time-series forecasting with interpretable machine learning, aug...

Auditory brainstem response deficits precede and are associated with subsequent auditory cortical amyloid burden in male APP/PS1 mice

Background Auditory dysfunction is considered one of the early manifestations of Alzheimer's disease (AD). However, its evolutionary characteristics with the progression of AD have not been fully studied, and the temporal relationship between this sensory impairment and the typic...

Bio-inspired functional recursion enables multi-mode locomotion in a 140-mg morphing microrobot

Insects traverse diverse environments by reusing body structures and appendages through adaptable mechanics, an ability that remains a grand challenge for insect-scale robotics under strict mass constraints. Here we present an insect‑scale robot that integrates aerial takeoff and...

Dynamics of emotion-transition networks link brain network variability and affective symptoms

Emotion dynamics are closely linked to psychological health. Although inertia and variability have been linked to affective symptoms, relatively few studies have examined how emotional states are structurally organized and transition from one state to another. Using ecological mo...

Mamba-OrthoNet: unified global–local feature fusion and angular encoding for accurate ship orientation detection

Abstract Accurate ship orientation detection in high-resolution remote-sensing imagery is vital for maritime monitoring, traffic management, and search-and-rescue. Yet port scenes are crowded and ships vary in scale: global context separates adjacent ships, while fine local cues...
