Real-Time LiDAR-Based Stair and Elevation Change Detection on Consumer Mobile Hardware: A Single-User Study

This paper presents and evaluates a computationally efficient, real-time algorithm running on consumer LiDAR-equipped smartphones that achieves a 92.5% detection rate for stairs and elevation changes with zero false positives, demonstrating the viability of low-cost, on-device assistive navigation tools for the blind and visually impaired despite inherent geometric limitations in descending approaches.

Bayesian-Calibrated Enthalpy Modeling for Thermal Regulation of Phase-Change-Assisted Electric Heat Tracing Systems

This study develops and validates a Bayesian-calibrated enthalpy model for a phase-change-material-assisted electric heat tracing system, demonstrating that the coordinated integration of active heating, latent heat buffering, and insulation significantly enhances thermal regulation and freezing protection for low-temperature pipelines compared to conventional methods.

Field Monitoring of Pore-Pressure Response in PVD-Treated Ganges–Brahmaputra–Meghna Deltaic Alluvium under Staged Highway Loading

This study presents the first peer-reviewed field monitoring of pore-pressure response in Ganges–Brahmaputra–Meghna deltaic alluvium under staged highway loading, revealing that critical pore pressures can occur before instrumentation and demonstrating that while PVDs significantly accelerate consolidation dissipation rates, they do not alter peak undrained pore-pressure responses, thereby providing regionally calibrated design parameters for eastern Bangladesh.

A Unified Space–Time Finite Element Solution Framework for Electromagnetic–Mechanical Coupling Problems

This paper presents a unified space–time finite element framework that integrates spatial and temporal discretization to solve electromagnetic–mechanical coupling problems, offering a stable, symplectic-preserving one-step recursive scheme that eliminates the numerical dissipation and energy drift associated with traditional semi-discrete methods.

Analysis of Safety Distances for Fire Brigade in Response to Confined-Space Hazardous Materials Accidents: A Case Study from South Korea

This study utilizes a 2025 South Korean hydrogen sulfide accident and ALOHA dispersion modeling to demonstrate that conventional qualitative safety zones often underestimate firefighter exposure risks, advocating instead for quantitative, concentration-based distance guidelines for confined-space hazardous material incidents.

An Open-Source OpenSeesPy Framework for Simplified Micro-Modeling and OMA-Based Model Updating of Masonry Infill Walls under Cyclic Loading

This paper presents a fully reproducible, open-source OpenSeesPy framework that validates a simplified micro-model against experimental cyclic and operational modal analysis data, revealing that the significant amplitude dependence of infill–frame interface stiffness necessitates distinct calibrations for small-amplitude dynamic characterization and large-amplitude seismic capacity modeling.

Direct-Write Transfer Printing of Low-Loss Copper Interconnects onto Arbitrary Substrates

This paper presents a direct-write transfer printing technique that decouples copper deposition from the target substrate via meniscus-confined electrodeposition, enabling the creation of low-loss, near-bulk conductivity interconnects with smooth surfaces on arbitrary and textured substrates for high-frequency wearable and bioelectronic applications.
