Fault Friction, Plate Rheology, and Mantle Torques From a Global Dynamic Model of Neotectonics

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Improvements in software, parallel computing, global data sets, and laboratory flow‐laws help to develop the global Earth5 thin‐shell finite‐element model of Bird et al. (2008, https://doi.org/10.1029/2007jb005460) into a benchmark study. All experiments confirm that modeled faults (other than megathrusts) have low effective friction of 0.085 ±

Analysis of Influencing Mechanism of Subgrade Frost Heave on Vehicle-Track Dynamic System

Applied Sciences, 2020
Uneven subgrade frost heave has been a severe problem for the operation of high-speed railways in cold regions. In order to reveal the influencing mechanism of frost heave on the vehicle-track system, a novel FEM (finite element method) model based on an

A Bio-Wicking System to Mitigate Capillary Water in Base Course [PDF]

, 2016
Water within pavement layers is the major cause of pavement deteriorations. High water content results in significant reduction in soil’s resilient behavior and increase in permanent deformation. Conventional drainage systems can only drain gravity water

Association rules between the microstructure and physical mechanical properties of rock-mass under coupled effect of freeze-thaw cycles and large temperature difference [PDF]

, 2017
The mechanical properties of fractured rock mass are largely dependent on the fracture structure under the coupling of freeze-thaw cycles and large temperature difference.

Decoupling Hydroclimatic Controls on Displacement of Retrogressive Thaw Slumps in Qinghai‐Tibet Plateau

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The retrogressive thaw slumps (RTS), a prevalent form of thermokarst hazard in permafrost regions, are increasing in both number and extent under contemporary changing environments. On the Qinghai‐Tibet Plateau, RTS threaten transportation infrastructure and disrupt ecosystems.

Inverse Grading Emerges From Particle‐Scale Migration Under Seasonal Freeze‐Thaw Forcing: Evidence From Multi‐Year Monitoring and Physical Modeling

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Inverse grading, where coarse particles overlay finer materials, is common on talus slopes, yet its progressive formation under realistic conditions is rarely quantified. We integrate multi‐year field observations with controlled freeze‐thaw experiments to elucidate the processes driving particle migration that result in inverse grading and ...

Interseeding strategies for legume integration into meadow fescue pastures

Crop Science, Volume 66, Issue 2, March/April 2026.
Abstract Forage legumes provide a wide range of ecosystem services to grasslands. Improving legume proportion and species diversity of meadow fescue [Lolium pratense (Huds.) Darbysh] pasture‐based systems can increase the sustainability of a given farming system. This study compared no‐till or frost‐seeding methods to incorporate clovers (Trifolium spp.

Morphological instability in restored intertidal flats: How anthropogenic structures drive early‐stage evolution

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
The study focusses on the morphological evolution of worldwide restored intertidal flats. These intertidal flats initially experience high sedimentation rates after the opening of the connection with open waters. The anthropogenic structures cause high morphological instability and are eroded, leading to a self‐cannibalisation of the system.
