Surface-Borehole Resistivity Tomography For Seepage Detection In Earth-Rock Dams, Tan Lei, Hu Xiongwu, Zhang Pingsong, Jiang Xiaoyi, Dong Ya, Liu Fuda, Li Chunyang, Xu Hu Feb 2026

Surface-Borehole Resistivity Tomography For Seepage Detection In Earth-Rock Dams, Tan Lei, Hu Xiongwu, Zhang Pingsong, Jiang Xiaoyi, Dong Ya, Liu Fuda, Li Chunyang, Xu Hu

Coal Geology & Exploration

Objective Resistivity methods allow for effective detection of seepage in reservoir dams. However, when used to detect the hidden hazards of dams, the surface resistivity method fails to accurately identify vulnerable areas across an entire dam due to blind spots near both dam abutments and insufficient resolutions for deep parts. Methods This study proposed a seepage detection technique for earth-rock dams based on surface-borehole resistivity tomography, followed by the analysis of the distribution of surface-borehole resistivity under the lateral and vertical variations in a seepage zone through numerical simulations. This technique was applied to the Shibi reservoir dam. Using the …

A Gaussian Process Regression-Based Denoising Method For Transient Electromagnetic Signals, Wang Peng, Shi Jiaxing, Lu Kai, Hu Jinru, Wen Guangyuan, Zhai Haojie Feb 2026

A Gaussian Process Regression-Based Denoising Method For Transient Electromagnetic Signals, Wang Peng, Shi Jiaxing, Lu Kai, Hu Jinru, Wen Guangyuan, Zhai Haojie

Coal Geology & Exploration

Objective The transient electromagnetic (TEM) method serves as a primary geophysical technique for groundwater detection in coalfields at present, with the detection results directly influencing the implementation of water hazard prevention and control in coal mines. Since it is difficult to avoid electromagnetic interference sources such as power lines during data acquisition, TEM signals are prone to be contaminated by electromagnetic noise. Given that primary denoising techniques such as wavelet transform and empirical mode decomposition (EMD) are yet to be further improved, this study developed a novel Gaussian process regression (GPR)-based denoising method for TEM signals. Methods First, time alignment …

Multiscale Fusion Aot-Gan Intelligent Filling Of Blank Strip For Formation Microresistivity Imaging Logging, Huang Luyi, Wang Fei, Kong Lingsong, Jiang Qishu

Coal Geology & Exploration

Objective Formation microresistivity imaging (FMI) images features incomplete borehole coverage and thus contain blank strips due to the gaps between electrode pads, as well as their pushing and attachment mechanisms. Traditional blank strip filling methods suffer from several limitations, including susceptibility to image distortion and difficulty in retaining information on fine-scale structures such as fractures. This study developed an aggregated contextual-transformation generative adversarial network (AOT-GAN) for blank strip filling, aiming to achieve high-precision and high-fidelity information reconstruction.

Cross-Modal Lidar-Camera Joint Calibration For Heading And Mining Face In Coal Mines, Yang Wenjuan, Ren Zhiteng, Zhang Xuhui, Du Yuyang, Li Changpeng, Zhang Chao, Xu Jie, Wan Jicheng, Lei Mengyu

Coal Geology & Exploration

Objective In underground coal mines, it is challenging to extract the features of the heading and mining face stably under insufficient illumination, significant dust interference, and sparse point clouds. This severely undermines the accuracy and robustness of camera-LiDAR joint calibration based on underground unstructured scene characteristics.Methods Targeting complex operating conditions, including fully mechanized mining face and tunneling roadways, this study developed a LiDAR-camera joint calibration method based on cross-depth feature coupling. In this method, an improved random sample consensus (RANSAC) algorithm for multi-plane fitting was designed for feature extraction. By integrating normal vector-based pre-clustering and an adaptive iteration mechanism, …

A Probabilistic Deep Learning Framework For Retrieving Chlorophyll-A From Hyperspectral Imagery: Integrating Channel Attention And Mixture Density Networks, Wenzhao Li, Surendra Maharjan, Rejoice Thomas, Junde Chen, Hesham Morgan, Michael J. Garay, Olga V. Kalashnikova, Shahryar Fazli, Charles Ichoku, Hesham El-Askary

Mathematics, Physics, and Computer Science Faculty Articles and Research

Accurate monitoring of Chlorophyll-a (Chla) is critical for assessing aquatic ecosystem health, yet ecological complexity often leads to ambiguous spectral signatures in satellite data. Traditional deterministic models assume a one-to-one mapping between spectra and pigments, often failing to capture these high-dimensional analytical challenges. In this study, we propose a novel deep learning architecture, the Channel Attention-Mixture Density Network (CA-MDN), to retrieve Chla from the National Aeronautics and Space Administration (NASA) Earth Surface Mineral Dust Source Investigation (EMIT) hyperspectral mission. The CA-MDN integrates an attention mechanism to dynamically select ecologically relevant spectral bands and employs a probabilistic output layer to quantify …

Monitoring Strategies In Cave Microclimate Studies, Nenad Buzjak, Dalibor Paar, Aurel Persoiu, Christos Pennos, Franci Gabrovšek, Valerija Rossi Feb 2026

Monitoring Strategies In Cave Microclimate Studies, Nenad Buzjak, Dalibor Paar, Aurel Persoiu, Christos Pennos, Franci Gabrovšek, Valerija Rossi

International Journal of Speleology

Cave atmospheres are spatially confined but dynamical systems that influence subterranean ecosystems, geomorphological processes, registration and preservation of climatic signals in sedimentary archives, cultural heritage, and conservation management. Despite major advances in cave climatology, methodological approaches to microclimate monitoring remain fragmented and are in some cases still shaped by the long-standing assumption that cave air temperature simply reflects the mean annual surface temperature. This paper revisits that assumption and develops an experience- and literature-based methodological framework for cave microclimate research. Key terminology is addressed by distinguishing between cave climate, cave microclimate, and cave meteorology, and by situating microclimatic variability within …

Vegetation Enhances Nitrogen Removal In Stormwater Ponds In Coastal South Carolina, Darcy Perin, Annie Bourbonnais Feb 2026

Vegetation Enhances Nitrogen Removal In Stormwater Ponds In Coastal South Carolina, Darcy Perin, Annie Bourbonnais

Faculty Publications

Coastal development and the increase in impervious surfaces lead to greater stormwater volumes, a key contributor to nonpoint source pollution. Stormwater ponds are generally highly efficient in eliminating particle-bound nutrients, such as phosphorus, but are often much less effective at removing dissolved nutrients, like nitrogen. Excess inorganic nitrogen can lead to coastal eutrophication, harmful cyanobacterial blooms, and coastal hypoxia. However, inorganic nitrogen can be removed from the environment through several different microbially facilitated processes. This research aims to estimate the rates of nitrogen removal (i.e., by denitrification), the net N2 fluxes, and internal recycling (DNRA) across the sediment-water interface …

School of Integrative Biological & Chemical Sciences Faculty Publications

Water pollution from industrial dyes is a critical challenge due to the resistance of these types of compounds to degradation and potentially harmful effects on living organisms and human health. In this study, the electrochemical degradation of methylene blue (MB) was investigated using ink-based copper foam electrodes with reduced graphene oxide (rGO), antimony trioxide (Sb2O3), and rGO/Sb2O3 composites. The materials used to synthesize the electrodes were characterized by X-ray diffraction (XRD), which showed the successful synthesis of GO, rGO, and the Sb2O3-rGO composite. Additionally, the synthesized electrodes were examined using SEM. The MB degradation was studied using kinetic behavior and …
