Identifying ecosystem service drivers to inform land use scenario simulation: An InVEST-PLSR-PLUS framework for the Danjiangkou Reservoir Basin, China

The Danjiangkou Reservoir Basin is the core water source of the Middle Route of China's South-to-North Water Diversion Project, yet research in this basin has largely focused on static ecosystem service (ES) assessments, leaving the drivers of ES dynamics and their future traject...

Numerical Simulation for Temperature Control and Crack Prevention of Tunnel-Lining Concrete During Construction

This paper develops a three-dimensional refined finite-element model for the typical concrete lining of the Dianzhong Water Diversion Project tunnel, investigates the temperature and stress fields of the lining, and systematically analyzes the influences of various temperature-co...

Nitrogen–Phosphorus Pollution Dynamics and Export Processes of Anthropogenic Polders in the Middle–Lower Yangtze River: A Regional Review

Polders are typical semi-artificial and human-dominated ecosystems widely distributed in the middle and lower reaches of the Yangtze River Basin. They serve as important sinks and sources of nitrogen (N) and phosphorus (P) in agricultural watersheds. Long-term intensive human int...

Dynamic Media Storage Links Antecedent Soil Moisture to Runoff Retention in Field-Scale Bioretention Systems

Antecedent soil moisture determines how much storage remains in bioretention media before rainfall, but its relationship with runoff control is poorly quantified. Three wet seasons of monitoring were analyzed for two field-scale bioretention systems with contrasting media depths,...

Stochastic Method for Calculating Lockage Capacity under Staggered Operation: A Case Study of the Gezhouba Lock Expansion Project

Abstract Because of constraints in space and budget, lock capacity expansion projects often adopt a layout in which multiple locks share a common approach channel. To prevent excessive water-level fluctuations and ensure navigation safety, a staggered operation mechanism must be...

Analysis on influencing factors for temperature control of concrete surrounding spiral case of hydropower station

The spiral case and its surrounding concrete (SCSC) are critical structural components and primary load-bearing elements for hydropower generation, necessitating stringent safety and reliability measures. The SCSC is a mass concrete structure, with temperature control typically a...

Escalating Uncertainty Under Increasing Risk in Compound Heat and Precipitation Extremes

Abstract Projection uncertainty fundamentally constrains climate adaptation, yet its evolution in compound heat and precipitation extremes (CHPE) remains poorly understood. Here we quantify CHPE uncertainty using 14 CMIP6 models and two single‐model initial‐condition large ensemb...

Association between beta-blocker selectivity and mortality in left heart failure patients with comorbid COPD

To evaluate the Impact of posterior to intensive care unit (ICU) beta-blockers use with the clinical outcomes in patients with left heart failure(LHF) and chronic obstructive pulmonary disease(COPD). Patients with LHF and COPD were selected from the Medical Information Mart for I...

Environmental DNA Metabarcoding Reveals the Variations in Fish Diversity Across the Yangtze River Basin and the Effects of the Three Gorges Dam

It is imperative that freshwater fish biodiversity research incorporates diverse components, encompassing taxonomy, phylogeny and function, alongside multifaceted facets, including richness, divergence and regularity. This comprehensive approach is essential to facilitate a more...
