Unveiling the cooling effects of urban green spaces in Eastern China: spatial heterogeneity, diurnal asymmetry, and nonlinear margins of 2D/3D features

Urban green spaces (UGS) play an important role in mitigating urban heat island effects. However, the mechanisms underlying their cooling effects are still not fully understood, particularly regarding the role of three-dimensional vegetation structure and nonlinear threshold resp...

Efficient nitrogen management as a win-win strategy for air quality, health, and climate

Reactive nitrogen (Nr) management links climate policy, air quality and food production, yet its combined impacts remain poorly quantified. Here, we conduct ensemble simulations with two global climate models, Goddard Institute for Space Studies (GISS) and Community Earth System...

Competition mechanisms of interfacial crack propagations in thermal barrier coatings

Abstract Cracking failure of thermal barrier coatings (TBCs) in advanced gas turbines under bending loads presents a persistent engineering challenge, particularly regarding how cracks compete and propagate through multilayer structures. This study addresses that challenge by con...

Aero-DETR: a frequency-adaptive sparse-interaction network for UAV-assisted aircraft surface defect detection

Abstract Aircraft surface defect inspection is critical for aviation safety but remains challenging because defects in unmanned aerial vehicle (UAV) imagery are often small, low-contrast, and multi-scale. We construct the aircraft UAV defect inspection dataset (AUDID), containing...

Fisher-Information-Based Cooperative Sensor Node Pre-Selection for UWB-Aided GNSS-Denied UAV Swarm Localization Under Heterogeneous Ranging Noise

Ultra-wideband (UWB) inter-node ranging provides relative-distance constraints for cooperative localization in GNSS-denied UAV swarms, but dense candidate networks can exceed the available ranging slots, communication bandwidth, computation, and energy. This paper proposes a Fish...

Analysis of the application of computerized optokinetic nystagmus analyzer in vision examination

To investigate the practicability, accuracy, and consistency of the computerized optokinetic nystagmus (OKN) analyzer for visual acuity (VA) measurement. Cross-sectional consistency evaluation study. A total of 219 subjects (13.48 ± 12.89 years, 115 males, 104 females) underwent...

Tracking the baryon number with nuclear collisions

Baryon quantum number is found to be conserved since baryogenesis in the early Universe. Conventionally, each fractionally charged valence quark is understood to carry one-third of a baryon number. An alternative hypothesis posits that baryon number is instead carried by a baryon...

Machine-Learning-Based Screening of Relative Eccentric-Wear Severity in Shield TBM Disc Cutters Using 3D-Scan Morphology Labels

Disc-cutter wear in abrasive strata is spatially non-uniform, yet mean wear depth cannot indicate where it concentrates. This retrospective feasibility study develops a machine-learning-based condition-monitoring framework that predicts the relative severity of eccentric wear fro...

Paleomagnetic Reconstruction of the Early Triassic Paleogeographic Position of the South Yellow Sea and Its Geological Significance

Most studies on the Early Triassic paleomagnetism of the Yangtze Block (YB) have concentrated on the Western to Middle parts, but the South Yellow Sea (SYS) in the Eastern YB (EYB) is relatively lacking. To ascertain the paleogeographic position of the SYS, we isolated the charac...

Flow field evolution mechanism and fine separation performance of coal slime in a novel cyclone cluster with a tapered column section

Single-stage hydrocyclones struggle to meet the requirements for the fine separation of coal slime. Existing combined hydrocyclones are constrained by the discharge capacity of the transverse underflow port, where the recirculation vortex at the bottom induces flow field instabil...

High-Precision UT1 Prediction with Different Angular Momentum Combination Schemes

Universal Time (UT1) is a core component of the Earth orientation parameters (EOP). High-precision UT1 predictions are essential for satellite navigation, deep-space exploration, and the maintenance of national standard time. Although effective angular momentum (EAM) information...

Bionic Flexible Wrinkled Strain Sensors With Water‑Accelerated Self‐healing Capability for Underwater Detection and Motion Interaction

Developing flexible sensors capable of long-term, high-sensitivity monitoring for flow fields and motion interactions is crucial for advancing unmanned underwater operations. However, flexible sensors always face challenges in achieving underwater superior self-healing performanc...

Exosomes mediate intercellular transmission of Tembusu virus via the NS4A-Rab27a axis

Abstract Accumulating data support the role of exosomes from virus-infected cells (especially RNA viruses) in the selective encapsulation of viral proteins, genomic material, and even whole virions, thereby mediating intercellular communication events and contributing to viral tr...

Biobased Fibrous Films Enabling Synergistic Thermal Conduction and Radiative Cooling for Personal Thermal Management

Abstract Personal thermal management materials are increasingly in demand under intensifying outdoor heat exposure and global warming. However, simultaneously achieving efficient radiative cooling, rapid thermal conduction, mechanical flexibility, and sustainability within a simp...

CFD Analysis of Drag and Internal Volume Tradeoffs in a Compact AUV with a Myring Forebody and Flat Stern

Low-slenderness-ratio, flat-ended autonomous underwater vehicles must balance hydrodynamic resistance against internal volume retention, yet classical slender-body criteria do not fully represent their coupled forebody wake response. A generalized Myring forebody was assessed for...

Unraveling the Ionic Adsorption and Migration Mechanism of Inverse Opal Capacitive Deionization Electrode

ABSTRACT Developing advanced capacitive deionization electrodes for desalination requires the concurrent enhancement of thermodynamic and kinetic properties. Despite extensive research on improving thermodynamic features represented by adsorption capacity, the investigation on th...

Advancing Energy Efficiency in Smart Windows via Dual‐Responsive Electro‐Thermochromism

ABSTRACT Implementing dynamic smart windows is imperative toward the construction of net‐zero buildings. However, the prevailing ion (de‐)embedding‐based electrochromic (EC) or thermosensitive hydrogel‐based thermochromic (TC) windows fail to achieve large optical modulation acro...

Flexural–Torsional Buckling Behavior of FGP Curved Beams Based on a Modified Variational Method

Abstract This study presents a modified variational modeling method for the flexural–torsional buckling of functionally graded porous (FGP) curved beams. Unlike conventional methods that rely on strictly admissible functions, the proposed framework accommodates arbitrary orthogon...

Antarctic Circumpolar Current creates a boundary limiting the meridional dispersal of bacteria in the Southern Ocean
