New Occurrence of Seifertite and Stishovite in Chang’E‐5 Regolith

Abstract High‐pressure minerals in impact ejecta quantify shock conditions and provide clues for provenance analysis. The sampling site of Chang’E‐5 may contain distal ejecta, which is critical for constraining the impact events and interpr...

ELF and VLF signatures of sprites registered onboard the low altitude satellite DEMETER

We report the observation of ELF and VLF signature of sprites recorded on the low altitude satellite DEMETER during thunderstorm activity. At an altitude of ~700 km, waves observed on the E-field spectrograms at mid-to-low latitudes duri...

Observational Properties of Harmonic EMIC Waves: Statistical Study

Abstract Electromagnetic ion cyclotron (EMIC) waves are discrete electromagnetic emissions separated by multiple ion gyrofrequencies. Harmonic EMIC waves are defined as waves with a strong electric or magnetic field (or both) at the harmoni...

Numerical simulation of irregular section underground structure shaking table test model

Based on the the large shaking table test results on irregular section subway station structure in soft soil, an overall time-history numerical simulation is conducted to study the nonlinear dynamic interaction of the soil-irregular undergr...

FROM BARCHAN TO DOMIC SHAPE: EVOLUTION OF A COASTAL SAND DUNE IN NORTHEASTERN BRAZIL BASED ON GPR SURVEY

ABSTRACT A sand dune located near São Bento do Norte and Caiçara do Norte towns (northern coastal region of Rio Grande do Norte state, Northeastern Brazil) is rapidly migrating toward urban areas. To understand the depositional processes (e...

Modulation of Mode‐Water Eddies on Upper Ocean Responses to Tropical Cyclones

Abstract The modulation of anticyclonic subsurface‐intensified mode‐water eddies (MWEs) on the oceanic physical and biological responses to tropical cyclones (TCs) is investigated using satellite measurements, in situ observations and numer...

Estimation of the Thickness of the Lunar Uppermost Basalt Layer Based on Lunar Radar Sounder Observations

Research on lunar basalt thickness and subsurface features is of great significance to conclude the magma evolution history and explore the thermal evolution process of the Moon. The mission of Lunar Radar Sounder (LRS) made subsurface dete...

Review of progress in passive seismic reflection exploration

Seismic exploration is a key method for the study of underground structures. Active seismic surveys can acquire high signal-to-noise ratio reflection data; however, the operation of active seismic surveys is complicated, and the exploration...

Two-Stage Framework for Efficient UAV-Based Wildfire Video Analysis With Adaptive Compression and Fire Source Detection

Uncrewed Aerial Vehicles (UAVs) have become increasingly important in disaster emergency response by facilitating aerial video analysis. Due to the limited computational resources available on UAVs, large models cannot be run efficiently fo...

Ice Nucleation Enhancement in Ambient Aerosols Under High‐Salinity Conditions: Insights From Cloud Chamber Experiments

Abstract Ice‐nucleating particles (INPs) play a role in mixed‐phase clouds, yet the processes controlling their properties remain poorly understood. Water‐soluble salts such as sodium chloride (NaCl) depress the freezing temperature of clou...

Correlations Between Subduction of Linear Oceanic Features and Arc Volcanism Volume Around the Pacific Basin

Abstract Arc volcanoes, created by magma generated from the dehydration of subducting slabs, show great variability in their sizes and along‐arc spatial distributions. In this study, we address a fundamental question, namely, how do subduct...

MFEFNet: An Efficient Network for Infrared Small Target Detection With Multiview Feature Extraction and Multiscale Attention Fusion

Infrared small target detection (IRSTD) remains a core challenge in remote sensing, mainly due to low signal-to-noise ratios, small target sizes, background interference, and large-scale variations. Although existing methods have achieved p...

The Beginning of a Wilson Cycle in an Accretionary Orogen: The Mongol–Okhotsk Ocean Opened Assisted by a Devonian Mantle Plume

Abstract The opening of oceans within accretionary orogens is important for understanding the Wilson cycle. The Mongol–Okhotsk Ocean (MOO) began opening within the early Paleozoic accretionary collage of the Central Asian Orogenic Belt (CAO...
