Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

open access: yesReviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Numerical investigation of the path-dependent frost heave process in frozen rock under different freezing conditions

open access: yesJournal of Rock Mechanics and Geotechnical Engineering
Frost heave in water-bearing rock masses poses significant threats to geotechnical engineering. This paper developed a novel three-dimensional (3D) frost model, based on the combined finite-discrete element method (FDEM), to investigate the frost heave ...

Subgrade Insulation to Prevent Soil Freezing, HR-87, 1965 [PDF]

open access: yes, 1965
The basic purpose of this study was to determine if an expanded polystyrene insulating board could prevent subgrade freezing and thereby reduce frost heave. The insulating board was placed between a nine inch P. C.

Invited review: Effect of temperature on a granular pile

open access: yes, 2010
As a fragile construction, a granular pile is very sensitive to minute external perturbations. In particular, it is now well established that a granular assembly is sensitive to variations of temperature.

Can Structural Tilt Be Measured From Exhumed Channel Belts on Mars? Numerical Experiments Using Analog Alluvial Strata

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Basin‐filling strata are Mars's historical record of depositional events, including sedimentation by alluvial rivers, and post‐depositional events, including tilting. Measuring stratal tilt on Mars could constrain post‐depositional processes, but is difficult to measure where exposures are 3D and lack clear stratal surfaces, as is often the ...

Study on the Influence of Frost Heaving on Defective Pipeline Stress in Frozen Soil Zone

open access: yesShiyou jixie, 2020
To ensure the safe operation of buried pipelines in frozen soil areas in cold season, in view of the frost heave conditions of buried pipelines with corrosion defects in the Sino-Russian Mojia section, ABAQUS is used to establish a three-dimensional ...

Churchill and Germany: A ‘Special’ Relationship

open access: yesHistory, Volume 111, Issue 395, Page 237-254, March 2026.
Abstract No other country defined the trajectory of Churchill's political career more than Germany, a country of which he had little direct knowledge but which he either sought to emulate, accommodate or oppose throughout his time in politics. This article traces Churchill's relationship with Germany from his entry into politics at the beginning of the

Altered Cytokine‐Induced STAT3 and STAT5 Activation of Peripheral T Follicular Helper Cells Contributes to Vaccine‐Non‐Responsiveness in Aging and HIV

open access: yesAging Cell, Volume 25, Issue 3, March 2026.
Chronic immune activation and inflammation associated with aging and HIV skew Tfh signaling toward enhanced IL‐2–STAT5 activation, reinforcing IL‐2R expression through a positive feedback loop and suppressing Tfh helper differentiation programs, thereby contributing to impaired vaccine responsiveness.

Freeze fracturing of elastic porous media: a mathematical model. [PDF]

open access: yes, 2015
We present a mathematical model of the fracturing of water-saturated rocks and other porous materials in cold climates. Ice growing inside porous rocks causes large pressures to develop that can significantly damage the rock.
