Research on unwrapping and stitching methods for borehole images

open access: yesGong-kuang zidonghua
Generating panoramic borehole wall images and "virtual cores" through image unwrapping and stitching is the basis for quantitative analysis of geological structures and is also an urgent need in borehole investigation.

Temporal Evolution of Contaminant Mass Discharge: Effect of Source Remediation at Contaminated Sites

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract Contaminant mass discharge (CMD) is a key metric for evaluating remediation performance at contaminated sites posing a risk to groundwater. This study assesses temporal CMD trends and associated uncertainties using a geostatistical approach at a chlorinated solvent contaminated site following source zone remediation, supported by two decades ...

Creating Perforations in the Sclerotic Region of the Proximal Tibia During Total Knee Arthroplasty to Enhance Prosthesis Stability

open access: yesOrthopaedic Surgery, Volume 17, Issue 5, Page 1397-1405, May 2025.
Abnormal stress in the proximal tibia modifies the bone mineral density distribution pattern, and drilling in the sclerotic region during total knee arthroplasty is correlated with enhanced prosthesis stability. ABSTRACT Objective In patients with varus deformity of the knee, the redistribution of the subchondral bone mineral density (BMD) of the tibia

Hydrologic effects of tidal wetland restoration in the subsided Sacramento‐San Joaquin Delta, California, United States

open access: yesRestoration Ecology, EarlyView.
Abstract Objective The Dutch Slough Tidal Restoration project in the Sacramento‐San Joaquin Delta involves flooding of delta lands; however, concerns have been raised that such flooding will increase the hydraulic pressures on subsided adjacent islands and threaten levee stability.

Coupled plagioclase dissolution and K‐feldspar overgrowth precipitation preserve anomalously high permeability in deeply buried sandstones

open access: yesSedimentology, EarlyView.
ABSTRACT This study investigated the formation mechanism responsible for anomalously high permeability (AHP) observed in the Eocene sandstones at depths from 3824 to 3832 m in the Huizhou Sag, Pearl River Mouth Basin, China, using helium porosity and permeability measurements, thin section, scanning electron microscopy, electron probe X‐ray ...

Fault‐Controlled Permeability: A Key Parameter in Geothermal Electricity Production Assessment

open access: yesTerra Nova, EarlyView.
ABSTRACT Geothermal energy is central to the global green energy transition, but its development has long focused on regions with positive thermal anomalies. Through a semi‐quantitative global‐scale review and spatial analysis of 361 geothermal sites, we show that 56.2% of global geothermal electricity production occurs in regions with thermal ...
