Research on unwrapping and stitching methods for borehole images
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
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 ...

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

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