Evaluative performance of triglyceride-glucose-frailty index versus surrogate insulin resistance indices for advanced cardiovascular-kidney-metabolic syndrome, cardiometabolic multimorbidity, and mortality: the role of estimated glomerular filtration rate

Cardiovascular-kidney-metabolic (CKM) syndrome and cardiometabolic multimorbidity (CMM) carry substantial mortality, yet whether a composite index integrating insulin resistance and frailty shows stronger associations with advanced CKM syndrome, CMM, and mortality than convention...

Defect Passivation of Mesoporous Al2O3-Based Buried Interface for Efficient Inverted Perovskite Solar Cells

Abstract Buried interface engineering between the hole transport layer and perovskite remains a critical challenge for inverted perovskite solar cells (IPSCs). Al2O3-based interface modification provides excellent interfacial stability and ion-blocking capability; however, its in...

Advances in layered double hydroxides with corrosion inhibitors for effective corrosion protection of magnesium and aluminum alloys: A review

Owing to their distinctive lamellar structure, compositional tunability, and excellent anion-exchange capability, layered double hydroxides (LDHs) can provide both passive barrier protection and active corrosion inhibition. Consequently, LDHs have emerged as highly versatile and...

Thermoresponsive mineral grout for autonomous oxygen isolation in underground coal pillars

A thermo-responsive mineral-based grout composite (GC) was developed for rapid sealing of fracture networks in underground coal pillars, aiming to eliminate oxygen ingress and prevent spontaneous combustion in goaf areas. Coal spontaneous combustion triggered by air leakage poses...

IFC-HFlowVAE: A self-enhancing generative framework with structural anchoring for imbalanced clinical data augmentation

Class imbalance and limited minority-class samples remain major challenges for developing reliable clinical diagnostic models, as insufficient observations often fail to capture complex minority-class distributions. Existing augmentation methods either rely on heuristic interpola...

Environmental drivers and machine-learning analysis of grapevine sap flow on hilly slopes in Southwest China

Global climate change has increased the frequency and intensity of high-temperature droughts, threatening fruit production in the fragile hilly regions of Southwest China. Grapevine ( Vitis labrusca×vinifera ‘Shine Muscat’ ) is widely grown there, but its sap flow dynamics under...

The dynamic and static mechanical properties of agricultural straw fiber reinforced cement soil and the evolution mechanism of the fiber-matrix interface microstructure

The research on the mechanical properties of agricultural straw fiber modified cement waste soil aims to explore the deficiencies in the mechanical performance of cement soil when using waste soil as raw material and its potential hazards. As a commonly used building material, th...

Design for Transportability of Modular Buildings: Quantitative Evaluation and Cross-Case Study

Abstract With the advancement of modular integrated construction (MiC), transportation has emerged as a critical link in the construction supply chain, directly impacting project cost, schedule, and safety. While design for manufacture and assembly (DfMA) prioritizes factory prod...

The Intrinsic Effect of Spontaneous Chemical Reduction on Phosphorus‐Doped Cobalt Toward Hydrazine Oxidation Reaction

ABSTRACT Transition metals (TMs) have caught great attention as the promising electrocatalysts for hydrazine oxidation reaction (HzOR). However, the critical factor that determines the superior HzOR activity on TMs has not been understood in‐depth, which hampers the precise desig...

Addressing anthropogenic noise and electrical anisotropy hints in magnetotelluric data from the Annecy area (French Pre-Alps)

The magnetotelluric (MT) method is a widely used tool for geothermal reservoir exploration due to its capability of imaging fluids in the Earth’s crust. However, in urbanised environments, its application is often challenged by anthropogenic noise and low signal-to-noise ratios....

Serum neutrophil elastase as a potential non-invasive biomarker for assessing hepatic fibrosis in chronic hepatitis B patients

The role of neutrophil elastase (NE) in liver fibrosis caused by chronic hepatitis B (CHB) has not been fully clarified. This study sought to measure serum NE concentrations in individuals with CHB and to determine whether NE could serve as a noninvasive indicator for assessing C...

Tomato leaf waste extract as corrosion inhibitor for copper–nickel alloy in H2SO4 medium

Abstract The tomato leaf waste extract (TLWE) was obtained through a decoction process and its effectiveness as a corrosion inhibitor on a copper–nickel alloy in sulfuric acid was assessed. Electrochemical measurements demonstrated that the extract functions as a mixed inhibition...

Improving Older Adults’ Social Interaction Quality with the Virtual Agent: Response Surface Model Based on Self-Disclosure Valence and Interpersonal Distance
