Intensifying Climate Extremes Over the Tibetan Plateau: Past–Future Changes and Implications for Railway Infrastructure

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Climate extremes over the Tibetan Plateau (TP) are intensifying and can threaten high‐altitude railways by altering permafrost stability, freeze–thaw regimes, drainage pressure, and hydro‐geomorphic hazards, yet their evolution for railways remains insufficiently quantified. Using CN05.1 observations (1961–2022) and an evaluated NEX‐GDDP‐CMIP6

Severity of perineal tears and deviations in perineal body anatomy: A three‐dimensional ultrasound study

Acta Obstetricia et Gynecologica Scandinavica, Volume 105, Issue 7, Page 1295-1302, July 2026.
Sonographic deviations in the muscles fusing into the perineal body were increasingly common with greater perineal tear severity 1 year after delivery in primiparous women. Abstract Introduction Perineal tears are classified into four degrees based on severity.

Numerical Investigation of the Influence of Interparticle Cohesion During the Shear Behavior of Granular Soil

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 9, Page 4020-4035, 25 June 2026.
ABSTRACT Interparticle cohesive forces play a crucial role in governing the shear behavior of many soils; however, quantifying this effect remains challenging due to limited microscopic insights available from laboratory experiments. In this context, the current study aims to investigate the influence of microscale cohesion on the shear response using ...

Experimental Study on Trenchless Treatment Technology of Differential Settlement of In-Service Highway Subgrade in Deep Soft Soil Area

Buildings
The highway network is densely distributed in the southeast coast of China. Highway subgrades passing through soft soil areas often produce large settlements, resulting in pavement cracking, bridgehead jumping, and other diseases.

From Hydraulic Heads to Dollars and Decision: It's Time to Integrate Groundwater in Coastal Risk Assessment

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Sea level rise presents a range of hazards, including rising groundwater tables, salinization, and subsurface flooding, which threaten subsurface infrastructure in coastal communities. Groundwater shoaling inundates basements, tunnels, and utility networks, and mobilizes contaminants, while salinization accelerates corrosion and deteriorates ...

State of the Practice − Sub‐Aqueous In‐Situ Solidification for Contaminated Sediment Remediation

Remediation Journal, Volume 36, Issue 4, Autumn 2026.
ABSTRACT In‐situ solidification (ISS) has emerged as a cost‐effective and versatile technology for sediment remediation, particularly for addressing contamination at greater sediment depths. This paper evaluates ISS in the context of conventional sediment remediation approaches, highlighting its advantages, design and implementation considerations, and

Computed Tomographic Grading of Ear Diseases in Guinea Pigs (Cavia porcellus)

Veterinary Radiology &Ultrasound, Volume 67, Issue 2, March 2026.
ABSTRACT Ear disease affecting the external and middle ears is a significant health concern in guinea pigs, which can be clinically silent and, if left untreated, can lead to severe and irreversible complications. Computed tomography (CT) is the primary imaging modality used to diagnose otitis in other species, particularly otitis media (OM).
