Diffusion Induced Chaos in a Closed Loop Thermosyphon [PDF]
SIAM Journal on Applied Mathematics, 1998 The dynamics of a closed loop thermosyphon are considered. The model assumes a prescribed heat flux along the loop wall and the contribution of axial diffusion. The well-posedness of the model which consists of a coupled ODE and PDE is shown for both the case with diffusion and without diffusion. Boundedness of solutions, the existence of an attractor,

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

Thermal Stability Analysis and Novel Cooling Technology Field Tests for Permafrost Railway Subgrades
Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Global warming has intensified the climatic warming and moistening trend on the Qinghai–Tibet Plateau, threatening the thermal stability of railway subgrades in the plateau permafrost regions. However, previous studies have lacked systematic analyses that comprehensively consider the climate along the railway, permafrost conditions, and subgrade ...
