Summary: This study proposes a novel diffraction separation method using the Fourier-based geometric-mode decomposition (GMDF) algorithm to remove reflections and separate diffractions. The GMDF algorithm effectively represents reflections with linear geometric features by adaptively decomposing seismic data into band-limited modes, and the alternating direction method of the multipliers algorithm is used to solve the GMDF optimization problem. The method demonstrates good performance in removing strong reflections and separating weak diffractions, providing interpreters with detailed structural and stratigraphic information.

Summary: It has been found that small earthquakes can cause changes in the chemical composition and isotopic ratios of cold springs. By continuously monitoring the X10 spring and conducting water chemistry analysis and isotope methods, the study reveals that the changes in chemical ion concentrations and hydrogen-oxygen isotope ratios in the X10 spring are related to local seismic activity. The study suggests that hydrogen and oxygen stable isotopes are more sensitive to seismic activity than commonly used chemical constituents, and combined monitoring of isotopes and water chemistry should be considered in the future to capture hydrogeochemical precursor signals caused by earthquakes.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
