Multi‐Interface Polarization Modulation in Cu@TiO 2 @MgO/PVDF for Enhanced Dielectric Constant and Breakdown Performances

ABSTRACT Decoupling control and collaborative improvement in both dielectric constant ( ε ) and breakdown strength ( E b ) while holding low loss of polymeric composites, constitutes a challenge for power electronics and energy storage systems. To realize this objective in copper...

Study on creep deformation behavior and constitutive model of filled fractured sandstone under freeze-thaw cycles

The time-dependent deformation and stability of fractured rock in seasonally frozen regions constitute a key scientific issue for engineering safety. To investigate the long-term deformation of fractured rock under the coupling of freeze-thaw (F-T) cycles and sustained loading, t...

Rock Pillar Fracture-Induced Vibration Characteristics and Rock Burst Mechanism in Steeply Inclined Extra-Thick Coal Seam Group Mining

Clarifying the dynamic mechanism of rock pillar fracture and its rock burst-inducing mechanism is fundamental for the prevention and control of rock burst disasters in steeply inclined extra-thick coal seam groups. In this study, field monitoring, theoretical analysis, and numeri...

Continuous automatic batch identification and characteristic analysis of vortex-induced vibrations of stay cables based on long-term monitoring

Vortex-induced vibration (VIV) is a typical abnormal vibration of stay cables, and long-term monitoring of VIV with in-depth information extraction is critical for bridge safety and maintenance. This study establishes an automatic batch framework for continuous VIV identification...

Compact Terahertz Vortex Beam Source Based on Smith–Purcell Radiation and a Double‐Layer Metasurface

ABSTRACT Smith–Purcell (SP) radiation, a frequency‐tunable radiation mechanism excited by moving electrons, is a promising route toward compact light sources operating from the terahertz to optical regimes. Vortex beams carrying orbital angular momentum (OAM) have helical phase f...

Influence mechanism of differences in hydrocarbon generation intensity of deep coalbed methane: a case study of the Daning-Jixian block

The deeply buried Upper Paleozoic coal seams in the Ordos Basin are regarded as the principal source rocks for natural gas accumulation. Accurately quantifying their hydrocarbon generation capacity and exploring the influencing mechanism of the difference in hydrocarbon generatio...

Image Inpainting in 30 Years: A Survey

ABSTRACT As a fundamental task in restoring continuous visual signals, image inpainting plays a critical role in autonomous driving perception, medical imaging, video editing and digital heritage preservation. Driven by deep learning and large‐scale generative models, the field h...

Multi-Objective Airflow Distribution Design in Mine Ventilation Systems Based on Sensitivity Screening and an Improved Multi-Objective Sparrow Search Algorithm

This study proposes a biomimetic multi-objective optimization framework for airflow distribution design in mine ventilation systems by integrating sensitivity screening with an improved multi-objective sparrow search algorithm (IMOSSA). The design problem is formulated with netwo...
