Abstract: Abstract A study was initiated to assess the thermal gradient-dependent deformation behavior of frozen soils at temperatures close to 0 °C and to reveal the mechanisms of this behavior. A series of unconfined compression tests (UCT)… read more here.

Abstract: The radially symmetric nonlinear reaction–diffusion equation with gradient-dependent diffusivity is investigated. We obtain conditions under which the equations admit second-order conditional Lie–Bäcklund symmetries and first-order Hamilton–Jacobi sign-invariants which preserve both signs (≥0 and ≤0) on… read more here.
