Eeg-based analysis of Driver cognitive load in subsea tunnel vs. Open Road: A Hybrid Machine learning and Statistical Modeling Approach

Driver cognitive load significantly impacts traffic safety, particularly in high-risk environments such as subsea tunnels. However, the complex effects of environmental factors and individual characteristics on cognitive load remain inadequately understood. To address this gap, t...

Hot-springs through time, and how to find them

Hot-springs have fascinated geologists including James Hutton for centuries. Here we synthesise data collected over timescales from centuries to days to reveal rules governing hot-springs, including where and when they occur. Data reveal waters dominantly sourced from the surface...

Effect of Nominal Fe Addition on the Microstructure, Wear Behavior, and Corrosion Resistance of Laser‐Clad CoCrNiFe x (TiNb) 0.2 High‐Entropy Alloy Coatings

CoCrNiFe x (TiNb) 0.2 ( x = 1.0, 0.75, 0.5, 0.25, and 0) high‐entropy alloy coatings were prepared on 30CrMo steel by laser cladding to clarify the effect of nominal Fe addition on microstructure, wear behavior, and corrosion resistance. All coatings were dominated by an FCC soli...

Aqueous‐Phase Process Accelerates OH Oxidation of Biomass‐Burning PAHs and Generates New Multifunctional Products

Abstract Biomass burning (BB) emits large amounts of polycyclic aromatic hydrocarbons (PAHs) and is an important source of secondary organic aerosol (SOA). Recent studies suggest that, compared with gas‐phase oxidation, the oxidation of BB‐emitted organics in atmospheric aqueous...

Study on the enhanced flotation performance of fine coal slime by microemulsion collector: simulation and experiment

Fine coal slime generally exhibits poor floatability, while conventional hydrocarbon oil collectors often suffer from limited flotation efficiency. To address these challenges, a microemulsion collector (OPAOW) was developed by integrating dissipative particle dynamics (DPD) simu...

Reconciling the Paradox of SO 2 in the High Temperature NH3‐SCR Reaction: The Role of SO 4 2− in Electronic Structure Remodeling and Mechanism Switching Over a 3DOM Ce‐W‐Ti‐Si Catalyst

ABSTRACT At present, the effect mechanism of SO 2 on high‐temperature denitrification catalysts is unclear. In this study, 3DOM CeWTi 1‐x ‐Si x O 2 catalysts were constructed for high‐temperature NH 3 ‐SCR reaction, and deeply explored the mechanism of SO 2 on the catalyst. Among...

A Replication of “It is Not Merely About the Content: How Rules Are Communicated Matters to Administrative Burden”

ABSTRACT This study replicates prior research to examine how rule communication forms shape administrative burden, while also extending their research by investigating how artificial intelligence (AI) services moderate this relationship. AI services are understood to perform two...

Separation of Methanol and MTBE Azeotrope via Choline-Based Deep Eutectic Solvents: Liquid–Liquid Equilibrium and Molecular Mechanism

Abstract Methyl tert-butyl ether (MTBE) is an excellent additive for gasoline. Because of the formation of an azeotropic mixture by MTBE and methanol during its production, it is a challenge to separate the azeotrope. To investigate the effect of hydrogen bond donor (HBD) functio...

Pb(II) Selectivity of Oxygen-Functionalized Lignite-Based Carbon Material in the Presence of Competitive Cu(II)/Cd(II) Interference

Abstract A series of lignite-derived activated carbons (CK-400-CK-700) was prepared by KOH activation to clarify the effects of pore structure and surface oxygen functionality on Pb(II) adsorption. Although the BET surface area increased from 456.60 to 1300.70 m2·g–1 with activat...

Lattice-Confined Rh Single Atoms in SrTiO3 Enable Leaching-Resistant and Durable Heterogeneous Hydroformylation

Abstract Heterogeneous Rh catalysts hold great promise for olefin hydroformylation by integrating the catalytic efficiency of Rh with facile separation and recycling. However, achieving high catalytic activity together with long-term stability remains a formidable challenge becau...

Study on high-efficiency arc direct-drive system based on beam oil pumping unit and dynamic performance

To shorten the surface transmission chain of conventional beam pumping units while improving compatibility between direct-drive actuation and the existing walking-beam structure, this study proposes an arc permanent-magnet synchronous motor (arc-PMSM) arranged along the walking-b...

A Composite Control Strategy for Permanent Magnet Synchronous Motor Drives Based on Improved Integral Sliding Mode Control and Three-Vector Model Predictive Current Control

Traditional model predictive current control (MPCC) usually applies only one voltage vector in each control cycle, which limits the voltage-vector regulation capability and may lead to relatively large steady-state current and torque ripple. Although the dual-vector method improv...

Transient heat and mass transfer of single and dual-cartridge respirators under extreme hygrothermal conditions: A coupled CFD and experimental study
