First Alps-wide reconstruction of LGM glacial sediment transport enabled by GPU-accelerated particle tracking [PDF]
Earth Surface DynamicsReconstructing the transport histories and provenances of glacial sediments and ice-contact deposits (e.g. tills, moraines) in formerly glaciated regions remains a major challenge, particularly at icefield- to ice-sheet scales and over multi-millennial ...

American Journal of Botany, EarlyView.Abstract Premise The origin of endemic species in the European Alps is commonly attributed to the climatic oscillations of the Quaternary. Moehringia sect. Moehringia, with 12 of 15 species endemic to the Alps and mostly restricted to well‐known glacial refugia, is a prime system for investigating the diversification of a lineage originating in the ...

American Journal of Community Psychology, EarlyView.Abstract US universities are built on stolen land and sustained through hierarchies of power that produce what migrant justice scholars name as b/order regimes. As institutions that claim to be sites of learning and inclusion, universities are fraught with contradictions as simultaneously sites of dispossession, exclusion, and control.

The impact of supraglacial ice cliff and pond formation on debris-free, tropical glacier mass loss
Journal of GlaciologyTropical Andean glaciers provide an important flux of freshwater to communities living both in high-altitude Cordillera and population centres downstream in countries such as Peru and Bolivia. Glacier recession threatens the sustainability of these water

Ac‐SDKP modulates apoptosis via HSP27 and the FAS/FASL and mitochondrial axes
Animal Models and Experimental Medicine, EarlyView.Schematic diagram of Ac‐SDKP regulating the FAS/FASL and mitochondrial apoptosis pathways via HSP27. Ac‐SDKP inhibits HSP27 expression, activates the FAS/FASL pathway and Caspase‐3 signaling, increases Caspase‐8 and Caspase‐3 expression, and induces cell apoptosis.

, 2008 During the past few decades the study of glaciers and their response to climate change has shown a strong development. Early theoretical work in the fifties and sixties has been complemented by the construction of numerical models of glaciers and ice sheets with various degrees of complexity.

Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT In this study, saponification variables were optimized using a face‐centred central composite design‐response surface methodology. The variables included reaction temperature (50°C–120°C), reaction time (30–180 min), KOH concentration (0.5–3 M) and pyrogallol concentration (0–1% w/v).

Optimising ice flow law parameters using borehole deformation measurements and numerical modelling
Geophysical Research Letters, 2008 Internal ice strain rates have been measured along two boreholes drilled through Glacier de Tsanfleuron, Switzerland. Differences between these measurements and the output from a 3D numerical model of glacier motion have been minimized by a scheme that ...

The Anatomical Record, EarlyView.Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...
