Geosciences, 2023 Rapid Arctic warming is expected to result in widespread permafrost degradation. However, observations show that site-specific conditions (vegetation and soils) may offset the reaction of permafrost to climate change.

Recent massive expansion of wildfire and its impact on active layer over pan-Arctic permafrost
Environmental Research Letters, 2023 Wildfire is recognized as an increasing threat to the southern boreal forests and the permafrost beneath them, with less occurring over the cold continuous permafrost than before.

Fluid transport in a thick layer above an active ciliated surface
Biophysical Journal, 1980 The discrete cilia approach is employed to describe the flow field above an active ciliated surface in a layer of finite depth. The infinite-size cilia surface model predicts a uniform flow above the cilia surface. Modifications as a result of a finitely extending cilia surface inside a finite-size dish predict a backward parabolic profile above an ...

Ultra-thin low frequency perfect sound absorber with high ratio of active area [PDF]
, 2018 A concept of ultra-thin low frequency perfect sound absorber is proposed and demonstrated experimentally. To minimize non-linear effects, an high ratio of active area to total area is used to avoid large localized amplitudes.

Closed-loop separation control over a sharp edge ramp using Genetic Programming [PDF]
, 2015 We experimentally perform open and closed-loop control of a separating turbulent boundary layer downstream from a sharp edge ramp. The turbulent boundary layer just above the separation point has a Reynolds number $Re_{\theta}\approx 3\,500$ based on ...
