Effects of thermo-erosion gullying on hydrologic flow networks, discharge and soil loss
Environmental Research Letters, 2014 Thermo-erosion gullies in continuous permafrost regions where ice-wedge polygons are widespread contribute and change the drainage of periglacial landscapes.

Universal axion backreaction in flux compactifications
Journal of High Energy Physics, 2021 We study the backreaction effect of a large axion field excursion on the saxion partner residing in the same N $$ \mathcal{N} $$ = 1 multiplet. Such configurations are relevant in attempts to realize axion monodromy inflation in string compactifications.

Modeling the spatiotemporal variability in subsurface thermal regimes across a low-relief polygonal tundra landscape [PDF]
The Cryosphere, 2016 Vast carbon stocks stored in permafrost soils of Arctic tundra are under risk of release to the atmosphere under warming climate scenarios. Ice-wedge polygons in the low-gradient polygonal tundra create a complex mosaic of microtopographic features ...

Two conjectures regarding dense near polygons with three points on each line
European journal of combinatorics (Print), 2003 We introduce two conjectures concerning the structure of dense near polygons with three points on each line. The first conjecture deals with the whole class of such near polygons.

Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Regional snow-avalanche detection using object-based image analysis of near-infrared aerial imagery [PDF]
Natural Hazards and Earth System Sciences, 2017 Snow avalanches are destructive mass movements in mountain regions that continue to claim lives and cause infrastructural damage and traffic detours. Given that avalanches often occur in remote and poorly accessible steep terrain, their detection and ...
