Summary: ERT is an effective tool for visualization and analysis of multiphase flow processes, but current deep learning networks for ERT image reconstruction are not well-trained. A new imaging algorithm based on dense connections is proposed to improve image reconstruction accuracy by fully fusing features between modules and mitigating information and gradient vanishing issues. The dense connections show good performance in promoting deep network training, leading to improved imaging accuracy compared to traditional methods.

Summary: The study found that the 2012 seismic sequence significantly influenced the distribution of soil gases in the area. Concentrations of all investigated species, except helium, increased after the mainshocks, likely due to crustal deformation promoting the uprising of geogas. In 2015, when the stress has dissipated, these concentrations gradually decreased towards pre-seismic levels.

Summary: Seismic imaging techniques are limited by the maximum frequency in observed waveforms, leading to a smoothed, effective version of the true medium. Homogenization theory helps compute effective properties of mediums with small-scale heterogeneities, and can be used in full waveform inversion. Two-stage multiscale methods break down the seismic imaging problem, revealing the benefits of using homogenization theory.

Summary: The aim of this paper is to create an integrated and free-access web platform for parcel irrigation water management on a large spatial scale. The platform aims to accurately determine the irrigation needs of main crops, design optimal adaptation strategies for the agricultural sector in the context of climate change, and incorporate the dynamic integration of information through a digital platform. This decision-making system considers factors such as real-time meteorological data, agricultural parcel information, crop evapotranspiration calculation algorithms, and satellite remote sensing techniques. The proposed platform has several novel points, including the derivation of parcel-level soil texture data from satellite imagery, comprehensive irrigation management information, and a user-friendly interface.

Summary: The objective of this study was to investigate the stability of the Acropolis Hill, Greece, by developing a Rock Instability Model (RIM) based on fuzzy logic and remote sensing techniques. RIM identified locations on the rock formations of the Acropolis Hill that were potentially unstable due to geomorphological factors, weathering, and erosive processes. The study highlighted the significant variables of lithology and slope angle in contributing to the overall stability of the Acropolis Hill, with the outcomes of the RIM model verified by remote sensing data and field observation.

Summary: This paper proposes a simple fully-connected PINN model to address long-standing challenges in seismic modeling and inversion, and evaluates its potential in interpolating and extrapolating scattered wavefields at multiple frequencies. The issue of spectral bias is tackled by incorporating the Kronecker neural network architecture with composite activation functions formed using atan, elu, l-sin, and l-cos. Numerical results demonstrate the efficacy of the proposed approach in fast and accurate, anisotropic multi-frequency wavefield modeling.
