Feasibility and perceptions among hemophilia patients and doctors towards ultrasound for the assessment of subclinical abnormalities in hemophilic joints

This study explores the feasibility and perceptions of using ultrasound (US) for identifying subclinical abnormalities in hemophilic joints from the perspectives of both patients and medical practitioners. This was a single-center pilot follow-up study that included multidiscipli...

A Consecutive Missing-Data Recovery Method for Bridge Health Monitoring Based on an ICEEMDAN-PE-LSTM-Informer Hybrid Model

Accurately reconstructing consecutive missing measurement segments presents a major challenge in bridge structural health monitoring, due to the inherent complexity and non-stationary nature of the collected signals. To address this, a hybrid data recovery framework is developed...

From conversation to green intention: how perceived AI chatbot empathy shapes sustainable travel

Recent developments in artificial intelligence (AI) have expanded the role of conversational agents in hospitality and travel service encounters. However, it remains unclear how the conversational characteristics of AI become psychologically meaningful and relate to travelers’ su...

Analysis of construction response for mechanized construction of metro connecting passages

To investigate the influence of mechanized pipe jacking construction for connecting passages in weathered granite strata on the settlement and deformation of left and right shield sections of metro tunnels and ground surface, this paper takes the pipe jacking project of No.1 conn...

Pu-Doping-Induced Weberite-like Local Motifs and Enhanced Immobilization in Gd2Zr2O7 Pyrochlore: A DFT + U Study

Abstract This study employs density functional theory with the Hubbard U correction (DFT + U) method to investigate how Pu incorporation into distinct sites (Gd or Zr) in Gd2Zr2O7 governs locally weberite-like disorder and subsequently influences Pu immobilization behavior. We re...

Paintable In Situ Gelling Bioelectronic Interfaces for Epidermal Electrophysiological Monitoring

Noninvasive epidermal electrophysiological monitoring is frequently constrained by unstable electrode-skin contact interfaces over soft, textured, and dynamically deforming skin. The predefined geometries of conventional electrodes limit their capacity to conform to local microto...

Concentration-Dependent Interlaminar Fracture Toughening in Carbon, Glass, and Hybrid Fiber-Reinforced Polymer Laminates via MWCNT Interlayers

Fiber-reinforced polymer (FRP) laminates are prone to delamination because they lack continuous through-thickness reinforcement. Although multi-walled carbon nanotube (MWCNT) interlayers can improve interlaminar resistance, evidence has focused mainly on unidirectional carbon fib...

Single-Molecule Studies Reveal That Water Starts to Protect Proteins Even at the ppm Level

Abstract A consensus established by extensive thermodynamic and structural studies of proteins and DNA is that water acts as an indispensable structural cofactor rather than a passive solvent for biomolecules. Nevertheless, it remains unclear whether trace water still exerts a st...

Simultaneous measurements of gas- and aerosol-phase water-soluble organic nitrogen in the winter urban atmosphere of Chengdu, China

Abstract. Partitioning gaseous water-soluble organic nitrogen (WSON) to the aerosol phase is a major formation pathway of atmospheric secondary organic aerosols (SOA). However, the factors influencing this WSON transfer process remain unclear. We conducted simultaneous wintertime...

Semantic–geography integrated spatiotemporal safety mapping for urban low-altitude airspace environments

Unmanned aerial vehicle (UAV) safety is becoming increasingly critical as UAV operations are integrated into urban service and transportation systems, creating an urgent need for risk representations that can support refined low-altitude airspace management. Existing urban safety...

LSTM-based prediction and parameter optimization analysis of sandstone subgrade compaction quality

The study proposes an LSTM-based framework for next-pass Compaction Energy Value (CEV) prediction and subsequent energy planning during sandstone subgrade compaction. Field tests were conducted at two sites, each divided into 24 spatial areas. For each completed compaction pass,...

Analysis of abnormal low-frequency lateral carbody sway in metro vehicles induced by alternating side wear of rails

Low-frequency carbody sway in the range of 2–3 Hz is a recurrent abnormal vibration phenomenon in metro systems, degrading ride comfort and operational stability. Field observations indicate that this vibration is concentrated in specific line sections and is closely associated w...

On operational adaptability of wear-resistant coatings for key components in electric vehicle differentials: A case study

During starting, rapid acceleration, and energy regeneration (with alternating forward and reverse rotation), EV differentials endure much higher instantaneous torque than conventional vehicles, greatly increasing wear and failure risk. Surface coating technologies thus offer a k...

A diffusion-based sequential generative workflow for AI-assisted architectural and structural design of detached houses

Traditional architectural and structural design workflows often require repetitive manual operations. Although recent artificial intelligence methods have advanced floor plan generation and structural design, most studies focus on isolated subtasks and simple residential datasets...

Hierarchy-dependent shear resistance and load sharing in root system reinforced soil: Insights from 3D DEM simulations

This paper investigates the shear reinforcement mechanisms of hierarchical tree root systems using three-dimensional discrete element method (DEM) simulations. A hierarchical root model based on Bischofia javanica was developed, explicitly representing taproots, lateral roots, an...

A Virtual Resistance-Capacitance Control Strategy for Mitigating Consecutive Commutation Failures in Weak Receiving-End HVDC Systems

In view of the high susceptibility of weak receiving-end High-Voltage Direct Current (HVDC) systems to consecutive commutation failures during AC faults on the inverter side, a novel virtual resistance-capacitance control strategy is proposed. This strategy is designed to suppres...

Cross-Lingual Real-Time Speech Interaction for Embodied Intelligence: Architecture, Challenges, and Prospects

Embodied intelligence is rapidly evolving toward natural human–machine interaction, where real-time cross-lingual speech processing is essential for robots to understand and execute commands across languages. This study reviews research progress from January 2010 to November 1, 2...

Bubble Engineering for Controlled Thermal Transport and Piezoresistive Sensing in Anti‐Icing Surfaces

ABSTRACT Efficient anti‐icing in extreme environments is fundamentally limited by rapid heat dissipation through continuous heat‐transfer pathways, which hinders stable thermal confinement at functional surfaces. Here, we report a strategy to regulate heat transport through engin...

More Accessible, More Equitable? Rehabilitation Support Spaces for Persons with Mental Disabilities in Tianjin

The equitable allocation of mental health rehabilitation support spaces provides an important foundation for community living and social participation among persons with mental disabilities. Existing accessibility studies tend to focus on a single facility type or travel mode, wi...
