Multiple Scattering Suppression in Heterogeneous Media: High‐Precision Imaging of Sleeve Grouting Defects Based on Elastic Reverse Time Migration

Engineering Reports, Volume 8, Issue 6, June 2026.
This study proposes an elastic wave reverse time migration (RTM) method to suppress multiple scattering noise in heterogeneous concrete. By effectively utilizing scattered wavefields, RTM enables high‐precision, robust imaging of sleeve grouting defects in prefabricated buildings, significantly outperforming traditional algorithms.

A Reduced Dimensional Emulator for Forecasting Equatorial Spread F

Space Weather, Volume 24, Issue 6, June 2026.
Abstract A machine learning emulator has been developed to efficiently reproduce electron densities from a three‐dimensional, data‐driven, regional simulation of postsunset ionospheric irregularities associated with equatorial spread F (ESF). The simulation has previously been shown to produce accurate ESF conditions observed at the Jicamarca Radio ...

Correction of Doppler-broadened Rayleigh backscattering effects in H2O dial measurements

, 1986
A general method of solutions for treating effects of Doppler-broadened Rayleigh backscattering in H2O Differential Absorption Lidar (DIAL) measurements are described and discussed. Errors in vertical DIAL measuremtns caused by this laser line broadening

Characteristics of Q-switched cladding-pumped ytterbium-doped fiber lasers with different high-energy fiber designs

, 2001
We theoretically and experimentally analyze Q-switched cladding pumped ytterbium-doped fiber lasers designed for high pulse energies. We compare the extractable energy from two high-energy fiber designs: (1) single- or few-moded low-NA large mode area ...

Daytime Ionospheric F‐Region Topside Irregularities Associated With Significant Density Enhancement at Low Latitudes During the 12 November 2025 Magnetic Storm

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract In this study, daytime F‐region irregularities were observed at low latitudes during the main phase of the 12 November 2025 strong magnetic storm, causing intense very high frequency radar echoes ranging hundreds of kilometers in altitude.
