Journal of GlaciologyTo investigate glacier mass loss and ice dynamics in northwestern Greenland, we measured surface mass balance (SMB), ice velocity and surface elevation from 2012 to 2025 on Qaanaaq Glacier, an outlet glacier of Qaanaaq Ice Cap.

An analytical model for wind-driven Arctic summer sea ice drift [PDF]
The Cryosphere, 2016 The authors present an analytical model for wind-driven free drift of sea ice that allows for an arbitrary mixture of ice and open water. The model includes an ice–ocean boundary layer with an Ekman spiral, forced by transfers of wind-input ...

Seasonal variability in Antarctic ice shelf velocities forced by sea surface height variations
The Cryosphere, 2022 Abstract. Antarctica’s ice shelves resist the flow of grounded ice towards the ocean through “buttressing” arising from their contact with ice rises, rumples, and lateral margins. Ice shelf thinning and retreat reduces buttressing, leading to increased delivery of mass to the ocean that adds to global sea level.

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation
Molecular Oncology, EarlyView.How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.

Experimental and numerical modeling of high speed ice impact onto rigid target [PDF]
, 2015 The core goal of this research is to develop an ice impact modelling methodology for ice impact on aircraft structures. The main current limitation of ice impact analysis is the ice constitutive model, so this research is focussed on the assessment and ...

Impact of Variable Atmospheric and Oceanic Form Drag on Simulations of Arctic Sea Ice [PDF]
, 2014 Over Arctic sea ice, pressure ridges and floe and melt pond edges all introduce discrete obstructions to the flow of air or water past the ice and are a source of form drag.

FEBS Open Bio, EarlyView.NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...
