“Forbidden” planes for Rayleigh waves [PDF]
Quarterly of Applied Mathematics, 2002 Summary: We discuss the existence of ``forbidden'' planes, on which Rayleigh waves cannot propagate. A mathematical model for anisotropic materials possessing ``forbidden'' planes is constructed, and an example of transversely isotropic material having ``forbidden'' planes is presented.

Advanced Science, EarlyView.A programmable passive digital shutter based on multiphase liquid–liquid interface dynamics is introduced for precise fabrication of hydrogel microfibers. By modulating the shutter operation, microfibers with tunable geometry—including linear, helical, tadpole‐like, and spherical forms—are produced.

On Some Problems Concerning the Seismic Field Methods [PDF]
, 1936 The periods of longitudinal waves produced by explosions increase with distance in a similar way as earthquake waves (equation 1). The amplitudes of the waves (equation 1) depend not only on the amount of energy reflected or refracted at discontinuities,

Shear wave structure of a transect of the Los Angeles basin from multimode surface waves and H/V spectral ratio analysis [PDF]
, 2020 We use broad-band stations of the ‘Los Angeles Syncline Seismic Interferometry Experiment’ (LASSIE) to perform a joint inversion of the Horizontal to Vertical spectral ratios (H/V) and multimode dispersion curves (phase and group velocity) for both ...

Advanced Science, EarlyView.This study presents a novel in situ laser‐induced breakdown spectroscopy system for monitoring metal vapors produced by the intense laser‐metal interactions in laser powder bed fusion additive manufacturing and laser welding. The insights from this new technique reveal changes in alloy compositions and provide the first in situ validation of multi ...

About applying Rayleigh formula based on the Kirchhoff integral equations for the seismic exploration problems [PDF]
Компьютерные исследования и моделирование, 2017 In this paper we present Rayleigh formulas obtained from Kirchhoff integral formulas, which can later be used to obtain migration images. The relevance of the studies conducted in the work is due to the widespread use of migration in the interests of ...

Real‐Time In Vivo Cellular‐Level Imaging During Puncture
Advanced Science, EarlyView.We present an artificial‐intelligence‐empowered integrative‐light‐field microendoscopy (AIM) needle that delivers real‐time in vivo, diffraction‐limited cellular‐level imaging during puncture and visualizes layered microstructures along the needle path. As a microscopic complement to CT/ultrasound, it improves sampling localization and adds preliminary
