Catalyst or Constraint? Direct Impacts and Spillovers of China’s E-Commerce Policy on Urban Spatial Restructuring via Nighttime Light Decomposition

Digital industrial policies are increasingly used to promote economic restructuring and spatial reorganization, yet their effects on urban spatial structure remain poorly understood. This study examines whether China’s National E-commerce Demonstration City (NEDC) policy acts as...

Response surface optimization and ultrasonic modification of soy protein isolate–gellan gum composite films

Abstract Soy protein isolate (SPI)-based films are promising biodegradable packaging materials but often have limitations in mechanical strength and barrier performance. In this study, gellan gum (GG) was incorporated into SPI films, and response surface methodology (RSM) based o...

Simulation of Acoustic Emission Between Mechanical Seal Interfaces Considering Elastohydrodynamic Lubrication Effects

Acoustic emission (AE) monitoring has been widely employed for condition assessment of mechanical seals. However, the physical origin of high-frequency AE activity under elastohydrodynamic lubrication (EHL) conditions remains insufficiently understood. To address this, a physics-...

TFCRNet: Dual-Discriminator SAR-to-Optical Translation and Region-Gated Cross-Attention Fusion for Thick-Cloud Removal

Thick-cloud contamination severely limits the usability of optical remote sensing imagery because cloud-covered regions may suffer from complete loss of surface information. Synthetic aperture radar (SAR) imagery provides complementary structural cues due to its cloud-penetrating...

Evolving frontiers in drinking water membrane technology: a 25-year bibliometric and antifouling perspective

Based on a comprehensive dataset of 5,925 publications retrieved from Scopus and the Web of Science Core Collection between 2000 and 2024, this study systematically maps the research landscape of membrane technology for drinking water production via integrated bibliometric analys...

PGMMF-Net: a POI-Guided Multi-modal Mamba Fusion Network for urban impervious surface extraction from optical and SAR imagery

Accurate extraction of urban impervious surfaces (IS) is essential for urban environmental analysis. However, optical-based methods are affected by shadows and spectral confusion, while optical-SAR fusion lacks urban functional semantics. Point-of-interest (POI) data provide comp...
