Characterization of coesite‐bearing impact melt glass from the Hapcheon crater, Korea: Trimodal phase architecture, shock metamorphism, and implications for 40Ar/39Ar geochronology

Meteoritics &Planetary Science, EarlyView.
Abstract We present the first micrometer‐scale, phase‐resolved compositional characterization of impact melt glass from the Hapcheon crater (~1.4 km apparent diameter), the first confirmed impact structure on the Korean Peninsula, integrating EPMA‐WDS (5 μm spot), confocal Raman spectroscopy (<1 μm spot), XRD, and 40Ar/39Ar step‐heating geochronology ...

Geophysical update of the diameter of the Zhamanshin impact structure, Kazakhstan

Meteoritics &Planetary Science, EarlyView.
Abstract The rim of the 0.9‐Ma‐old Zhamanshin impact crater in Kazakhstan is considered to be almost completely exposed via a series of hills surrounding a central flat area, indicating an apparent diameter of 14 km. This would make Zhamanshin the second largest impact crater of the Quaternary period. However, the overall geometry of these hills is not

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

Orthopaedic 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

Restoration 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.

Pipe Water, Employment and Health: A Gendered Analysis in India

Review of Development Economics, EarlyView.
ABSTRACT This paper examines the impact of indoor piped drinking water (IPDW) on gender disparities in employment and health in India, using panel data from the India Human Development Survey (2005–2012). Employing a differences‐in‐differences (DID) model with heterogeneous treatment effects, the analysis reveals that IPDW access increases rural women ...
