Passive seismic methods in highly populated urban areas have gained much attention from geophysics and civil engineering communities because traditional surveys, especially complex urbanized environments, might be improperly applied. In passive methods, directional noise sources will inevitably bring azimuthal effects spatial aliasing to dispersion measurements due the fact that true randomness of ambient cannot achieved reality. To solve these problems, multichannel analysis surface (MAPS)...
High-frequency surface-wave techniques are widely used to estimate S-wave velocity of near-surface materials. Surface-wave methods based on inversions dispersion curves only suitable laterally homogeneous or smoothly varying heterogeneous earth models due the layered-model assumption during calculation curves. Waveform inversion directly fits waveform observed data, and it can be applied any kinds models. We have Love-wave in time domain velocity. finite-difference method as forward modeling...
Non-antiviral therapeutic options are required for the treatment of hospitalised patients with COVID-19. CD24Fc is an immunomodulator potential to reduce exaggerated inflammatory response tissue injuries. We aimed evaluate safety and efficacy in adults COVID-19 receiving oxygen support.
<title>Abstract</title> Electromagnetic precursor anomalies are an important indicator for earthquake prediction, with numerous observations, simulations, and theoretical studies available. However, the generation process of electromagnetic waves, particularly their frequency characteristics, before has not been thoroughly studied. This issue is crucial in determining whether signal can penetrate stratum, significantly impacting research on prediction. paper explores waves generated...
The D-region ionosphere (60–100 km altitude) is critical for radio communication and space weather research but cannot be easily measured because it too low satellites high balloons. most effective technique to remotely sense by measuring Very-Low-Frequency (VLF, 3–30 kHz) waves emitted from man-made transmitters, a that was traditionally utilized estimate the average ionospheric condition between transmitter receiver. Recently, various methods have been proposed in large areas using network...
The energetic particle precipitations (EPPs), which include solar proton events (SPEs) and electron (EEPs), can significantly impact ozone levels in the polar middle atmosphere through two main mechanisms. One is direct that protons attend mesosphere catalyze depletion ionized odd hydrogen. Another indirect downward branch of residual circulation transports nitrogen to stratosphere causes a long&#8208;term effect on ozone. In this study, we conduct case studies statistical analyses...
During geomagnetic storm, large fluxes of energetic particles can precipitate into the Earth&#8217;s atmosphere and causes excess ionization therein [Ni et al., GRL, 35, 11, 2008], ultimately leading to depletion polar ozone layer. The subionospheric Very Low Frequency (VLF, 3-30 kHz) technique has been widely utilized study those space weather events that influence D-region ionosphere, including electron precipitation from radiation belts [Inan, 17, 6, 1990; Rodger, RG, 37, 317, 1999;...
Abstract Through the emission of high‐frequency radio waves, ground‐based heating facilities can generate Extremely‐Low‐Frequency (ELF) and Very‐Low‐Frequency (VLF) waves in ionosphere, a portion which penetrate into Earth's radiation belts influence electron population therein. Although various measurements ELF/VLF generated by ionospheric experiments have been reported, combined analysis using both observations simulations remain quite limited and, thus, underlying effects these are not...
Abstract. Antarctica is mostly covered by snow, firn, and glacier ice, the transformation from snow to firn ice influences energy transfer material transport in polar regions. In this paper, we deployed three linear seismic arrays near Dome A East during China's 39th Antarctic scientific expedition used ambient noise reconstruct structure nearby. The result shows that mainly comes Kunlun Station related human activities. We resolved empirical Green's function contains abundant multi-modal...

Multichannel analysis of surface waves (MASW) method analyses high-frequency to determine shear (S)-wave velocities near-surface materials, which are usually unconsolidated and possess higher Poisson's ratios. One key steps using the MASW obtain S-wave is pick correct phase in dispersive images. A seismic survey conducted over materials with a ratio will often result data that contains non-geometric wave, raise an additional energy dispersion image. Failure identify it may misidentification....
Abstract Aiming for a geophysical survey to around 1.5 km depth, we conduct passive‐source surface‐wave along 70‐km‐long line on the western side of Junggar basin in northwest China. We use frequency–time analysis and spatial autocorrelation methods extract dispersion curves from ambient‐noise data station pairs, as well multichannel surface waves multistations. Dispersion corresponding same positions obtained by these three independently are comparable, which shows validity using methods....
SUMMARY In near-surface surveys, shallow-seismic and ground-penetrating radar (GPR) full-waveform inversions (FWIs) have received increasing attention because of their ability to reconstruct high-resolution subsurface models. However, they different sensitivities the same targets thus may yield conflicting geophysical parameter To solve this issue, we developed an indirect joint petrophysical inversion (JPI) integrating multi-offset GPR data. These data are used porosity saturation whereby...
SUMMARY 2-D full-waveform inversion (FWI) of shallow-seismic wavefields has recently become a novel way to reconstruct S-wave velocity models the shallow subsurface with high vertical and lateral resolution. In most applications, seismic wave attenuation is ignored or considered as passive modelling parameter only. this study, we explore feasibility performance multiparameter viscoelastic FWI in which velocities P S waves, respectively, mass density are inverted simultaneously.
