Simulation of Discharge Evolution in the Main Streams of Large Rivers Using a Deep Learning Model: A Case Study of the Yellow River, China

Abstract Simulating river discharge evolution is fundamental to water resources management in large river basins. Nevertheless, human activities such as intensive water abstraction, reservoir operation, and other anthropogenic interventions have rendered the patterns of river dis...

Widespread spring discharge drives major water–salt–heat fluxes in salt marshes

Abstract The occurrence, spatial distribution, and flux significance of submarine groundwater discharge (SGD) through preferential pathways in low‐permeability salt marshes remain poorly understood. Using thermal infrared imaging and in situ measurements, we mapped 983 saline spr...

Has hydrological alteration driven ecosystem service risks in large floodplain lakes? A novel framework for spatiotemporal assessment and hydrological thresholds identification

Study region Poyang Lake, China’s largest freshwater lake, is a critical ecological hub. Study focus Hydrological alteration strongly affects floodplain ecosystem services (ES), yet their spatiotemporal risks and hydrological controls remain poorly understood. We developed an int...

Can the mitigation of water constraints promote regional entrepreneurial activity? Evidence from China

Traditional entrepreneurial choice models typically consider only entrepreneurial talent and capital inputs, neglecting natural resource endowments. The debate over whether the scarcity of natural resources affects regional entrepreneurial activity remains inconclusive. In countr...

Electric Vehicle Routing Problem with Time Windows and Flexible Service Locations

The rapid development of shared delivery, parcel lockers, and community pickup services has enabled customers to receive orders at multiple alternative service locations. In such scenarios, the fixed-location assumption adopted in traditional electric vehicle routing problems is...

Artificial Intelligence Adoption and Corporate Biodiversity Concern: Evidence from Chinese Listed Firms

Given the growing ecological and economic risks posed by biodiversity loss, this study uses panel data on Chinese A-share listed firms from 2010 to 2023 and employs a debiased machine learning approach to empirically investigate the impact of artificial intelligence (AI) adoption...

Semantic‐Aware UAV‐IRS Control for Cooperative V2X Perception Using Label‐Derived Context

ABSTRACT Cooperative V2X perception requires timely, reliable delivery of perception‐critical packets, especially when occlusion, dense traffic, and vulnerable road users increase scene risk. Existing UAV‐assisted intelligent reflecting surface (IRS) studies mainly optimize chann...

Study on mechanical properties and damage evolution of mortar reinforced by mixing basalt, carbon and polyester fibres in pairs

Fibre-reinforced mortar (FRM) has attracted much attention owing to its excellent mechanical properties. To further explore the influence of blended fibres on the mechanical properties and damage evolution of internal cracks in FRM, the effects of blended additions of basalt fibr...

Water Transport Characteristics and Their Impaction on Stability of Unsaturated Xiashu Loess Slopes During the Entire Process of Rainfall Infiltration

The Xiashu loess in the middle and lower reaches of the Yangtze River with typical aeolian characteristics is widely distributed in the hilly areas and is the main kind of landslides in this area. The paper reveals the infiltration process of the Xiashu loess slope under differen...

Hippopotamus optimization based control approach for performance enhancement of photovoltaic systems

Photovoltaic (PV) systems are widely integrated into the conventional power grid. It becomes a fundamental way for the energy landscape. One of the major challenges in deploying these technological resources is the grid’s instability. Therefore, enhancing the control strategy is...

Synergies and trade-offs for reaching global biodiversity and climate commitments

The Kunming-Montreal Global Biodiversity Framework strives to expand high-quality protected areas globally, yet faces economic constraints, climate change and human pressures. This requires integrating biological and socio-economic complexity while ensuring equity. We explore mul...

Micro- and NanobubblesEnhance the Abatement of BiodegradableMicropollutants in Aged Biological Activated Carbon Filters

Abstract It has been demonstrated that the abatement of micropollutants in drinking water by biological activated carbon (BAC) filters with aged media deteriorates due to the decreased porosity and aerobic metabolism in dense biofilm. In this study, micro- and nanobubbles (MNBs)...

Flocculation Characteristics and Dewatering Performance of Bored Pile Waste Slurry with Different Flocculants

Bored pile waste slurry generated during bridge substructure construction exhibits high water content and stable colloidal properties, resulting in difficult solid–liquid separation and severe environmental risks. To improve solid–liquid separation and facilitate efficient dispos...

A Sociological Perspective on Cultural Exchange through Social media: Connecting Traditions, Values, and Global Audiences

Social media platforms have become transnational spaces in which cultural traditions, values, and identities are circulated, interpreted, and contested. This study examines how social media users engage with cross-cultural content and how they perceive its contribution to cultura...

A Two-Stage Machine Learning Framework for High-Resolution Multi-Source Precipitation Fusion in Complex Terrain: A Case Study of Shaoxing, China

High-resolution precipitation fields are essential for flash-flood forecasting and hydrological risk management, especially in small and medium-sized basins, yet single-source precipitation products often show limited accuracy over complex terrain. This study develops a two-stage...

Tribological Behavior and Attachment Force Regulation of Bioinspired Claw–Spines

This study investigates the tribological behavior of the attachment force between bio-inspired claw–spines and rough surfaces and conducts theoretical and model-based analyses of the corresponding attachment mechanism. Based on critical interfacial tribological theory, a friction...
