Remote Sensing, 2018 Most high-altitude lakes are more sensitive to global warming than the regional atmosphere. However, most existing climate models produce unrealistic surface temperatures on the Tibetan Plateau (TP) lakes, and few studies have focused on the influence of

Regional Variability and Drivers of Below Ice CO2 in Boreal and Subarctic Lakes [PDF]
, 2015 Northern lakes are ice-covered for considerable portions of the year, where carbon dioxide (CO2) can accumulate below ice, subsequently leading to high CO2 emissions at ice-melt.

One-dimensional simulation of lake and ice dynamics during winter
Journal of Limnology, 2014 An ice formation model, based on the solution of the heat conduction equation across blue ice, white ice and snow cover, is integrated into the Dynamic Reservoir Simulation Model (DYRESM) to allow for one-dimensional (vertical) winter simulation of lake ...

Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells
Molecular Oncology, EarlyView.We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox

Application of a simple model for ice growth to the Lake St. Moritz, Switzerland
Journal of Glaciology, 2023 We present a Simple Lake Ice Model to calculate the growth rate of lake ice in a cold and relatively dry climate. The focus is on Lake St. Moritz, Switzerland, which has an area of 0.78 km2 and is about 45 m deep.

Hydrographic measurements in Jökulsárlón lagoon, Iceland [PDF]
, 2013 Jökulsárlón lagoon is an enclosed lake bordering the retreating Breidamerkurjökull glacier which flows down from the Vatnajökull ice cap. As the glacier calves most of the ice it releases decays within the lake and the addition of the stored fresh water ...

Holocene thermokarst and pingo development in the Kolyma Lowland (NE Siberia) [PDF]
, 2018 Ground ice and sedimentary records of a pingo exposure reveal insights into Holocene permafrost, landscape and climate dynamics. Early to mid‐Holocene thermokarst lake deposits contain rich floral and faunal paleoassemblages, which indicate lake ...

Molecular Oncology, EarlyView.Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

Remote sensing of lake ice phenology in Alaska
Environmental Research Letters, 2021 The timing of lake ice breakup and freezeup are important indicators of climate change in Arctic and boreal regions because they respond rapidly and directly to variations in climate conditions.
