A Distributed-Acoustic-Sensing-Based Method for Early Warning of Urban Road Subsurface Cavities Using Vehicle-Induced Vibrations

Rapid underground development in cities increases the hidden risks of roadbed cavities. Traditional geophysical methods, such as ground-penetrating radar (GPR), are costly and unsuitable for automated large-scale monitoring. This paper proposes a distributed-acoustic-sensing (DAS...

Rights configuration in China's governance of low-altitude airspace for drone operations: A bundle-of-rights analysis

Against the backdrop of the rapid expansion of low-altitude drone operations and emerging urban air mobility, this study examines the configuration of rights in China's governance of low-altitude airspace for drone operations, with particular attention to whether the existing leg...

Impact-Induced Damage Localization and Post-Damage Electrochemical Response of Multilayer Protective Coatings on Carbon and Weathering Steels

Mechanical impact during transportation and construction can locally damage protective coatings on steel bridge components and affect their subsequent barrier response. In this study, conventional baseline and modified multilayer coating systems were prepared on Q235B carbon stee...

Joint Optimization of Multi-Port Berth Allocation and Ship Lock Scheduling in River–Sea Direct Transport

River–sea direct transport systems emerging along the Pinglu Canal connect coastal and inland port clusters through shared lock facilities. When berth and lock resources are planned independently, uneven port workloads, mismatched vessel flows, and avoidable waiting may arise. Th...

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...

Quinoline-Based Amide Foldamers with One-Handed Chirality Induced by an Asymmetric Plane

Abstract A quinoline-containing cyclophane derivative with planar chirality was rationally designed and synthesized based on [2.2]paracyclophane (PCP) and used as a structural unit to induce the absolute one-handed helical conformation of quinoline foldamers. 1H NMR, X-ray crysta...

Bias-reconfigurable barrier photodetectors for integrated broadband sensing and neuromorphic vision

Intelligent vision systems demand photodetectors with reconfigurable response to support diverse modalities like high-speed sensing and neuromorphic processing. Here we show a bias-reconfigurable barrier photodetector that enables continuous modulation of response time across 7 o...

Evaluation of the Global Fibrinolytic Capacity of Whole Blood

Abstract Assessment of the global fibrinolytic capacity of whole blood is of great clinical value for the diagnosis of bleeding and thrombotic disorders, the guidance of therapeutic decision-making, and prognosis monitoring. However, due to the complexity of the fibrinolytic syst...

Multimodal Feedback-Enhanced Soft Hand Rehabilitation Robot: System Development and Preliminary Clinical Evaluation

Soft robotic systems have attracted increasing attention for hand rehabilitation because of their compliance, adaptability, and potential for comfortable human–robot interaction. However, the clinical translation of soft hand rehabilitation robots remains limited by insufficient...

Integrated optimization of collection point selection, UAV routing, and upload scheduling for UAV-aided data collection

Unmanned aerial vehicles (UAVs) provide a flexible means of collecting data from spatially distributed sensor networks in intelligent transportation systems. This study investigates a UAV-assisted data collection problem that jointly optimizes collection point (CP) selection, UAV...

Diverse coupling between climate change, socio-economic factors and climate potential productivity in Africa

Africa’s accelerating climate warming has rendered its climate potential productivity (CPP) increasingly vulnerable, raising global concerns over biodiversity, water resources, and food security. Understanding the long‑term evolution of CPP and its driving mechanisms has therefor...

Static-dynamic triggering mechanisms of rockburst in straight-walled arch roadways under different principal stress orientations and impact disturbances

This study investigates how principal-stress orientation affects impact disturbance triggered rockburst around straight-walled arch roadways. Coupled static-dynamic loading tests were conducted on specimens containing a straight-walled arch opening with orientation angles of 0°,...

Active Blood Cell Capture and Synergistic Coassembly: Self-Gelling Gelatin-Polysaccharide Powders for Rapid Hemostasis

While effective for irregular wounds, traditional hemostatic powders often lack posthydration cross-linking, yielding fragile barriers susceptible to washout under high-pressure hemorrhage. To address this, a novel self-gelling composite powder (GOQL) was developed by incorporati...

AI-mediated informal digital learning of English in Kazakhstan and Uzbekistan: The roles of L2 motivational selves and learner resilience

The rapid development of generative artificial intelligence (AI) has reshaped informal digital learning, yet most research has focused on well-resourced contexts and often treats AI-mediated learning as a standalone phenomenon. This leaves a limited understanding of how learners...

Constrained Dynamic Matrix Control of HRSG Water–Steam Chemistry Under Measurable Disturbances
