Mechanistic investigation of the bond-slip behavior of brick-mortar interfaces: From mortar decay to interfacial deterioration under sulfate attack

The bond-slip behavior at the brick-mortar interface plays a pivotal role in the long-term structural integrity of ancient masonry pagodas. Sticky rice paper pulp mortar (SRPPM), a key traditional material, is susceptible to environmental erosion. However, the quantitative link b...

Practical Prescribed‐Time Control for Strict‐Feedback Nonlinear Systems Subject to Sensor Faults and Input Saturation

ABSTRACT This article proposes a novel and practical prescribed time control (PPTC) method for strict feedback nonlinear systems (SFNSs) subject to input saturation and sensor faults. This method fills the research gap in existing literature, which only addresses a single constra...

Explainable Machine Learning Combined with Feature Selection and Bayesian Optimization for Predicting Rare Earth Elements and Yttrium in Coal: A Case Study of China’s Five Major Coal-Bearing Regions

Abstract Determining the concentrations of rare earth elements and yttrium (REY) in coal is essential for evaluating coal-hosted critical metal resources and understanding their geochemical controls. However, conventional laboratory analyses are costly, time-consuming, and spatia...

Seismic upgrading of an RC frame building using double-stage yield buckling-restrained braces

Nowadays, a large number of existing reinforced concrete (RC) structures require strengthening to meet the new building functions and enhanced seismic demands. Double-stage yield buckling-restrained braces (DYBRBs), capable of yielding at different seismic intensities, offer a pr...

Flame spread over flowing fuel under ignition delay: Spread and merging of flame front and fuel flow front

This paper investigates the flame spread over flowing liquid fuel under different ignition delays ( x ig ), substrate slopes ( θ ) and fuel discharge flow rates ( Q ). Focusing on flame front and fuel flow front, their spread and merging behavior, are concerned herein. Results sh...

Low-Velocity Impact Response and Residual Burst Strength of Fiber-Wound Composite Pressure Vessels

The increasing use of lightweight fiber-wound composite pressure vessels in energy-storage and transportation applications has heightened the need to understand impact-induced structural damage and the associated degradation in residual load-bearing capacity. Despite their superi...

Developing COLLAT: Initial validation of a multidimensional collocation awareness assessment using signal detection and Rasch modeling

Research on multiword expressions—including collocations, idioms, and lexical bundles—has advanced substantially; however, most assessments focus on accuracy- and knowledge-oriented measures rather than the awareness processes underlying that knowledge. This article reports the d...

Multidimensional Vegetation Drought Response to Meteorological and Soil Moisture Deficits Across the Yellow River Basin

Drought poses substantial threats to terrestrial ecosystems, yet whether vegetation vulnerability patterns systematically diverge between soil moisture and meteorological droughts—and how long-term hydrological adaptation governs ecosystem susceptibility to rare extreme droughts—...

Departmental Variability in Inpatient Medical Experience and Its Association With Satisfaction: An Exploratory Cross-Sectional Survey-Based Analysis

Objectives This study aims to explore the internal relationship between inpatient satisfaction (IS), the built environment, and medical experience (ME) throughout the medical treatment process. Background The inpatient environmental conditions and treatment procedures of differen...

A NESO-TD-based dual-loop integral sliding mode control framework for robust trajectory tracking of wheeled mobile robots

Wheeled mobile robots (WMRs) operating on rough outdoor compacted hard ground are susceptible to disturbances caused by model uncertainties and terrain variations, which may degrade trajectory tracking accuracy and robustness. To address this issue, this study proposes a unified...

Post‐Oxidation Integrating Assembly‐Confined Pyrolysis to Boost POD‐Like Activity of Non‐Metal Nanozyme and Engineer Colorimetric Hydrogel for On‐Site Detection of PFAS
