An adaptive finite volume solver for ice sheets and glaciers [PDF]
Journal of Geophysical Research: Earth Surface, 2010 We have developed a new adaptive finite volume scheme for numerical simulations of ice sheets and glaciers. The mathematical basis of the adaptive solver is represented by the finite volume method and irregular Voronoi cell grids. Evaluation of spatial derivatives are obtained at cell edges from approximating the ice surface elevation locally by second‐

Advanced Functional Materials, EarlyView.Rapid microwave plasma torch engineering tunes crystal phases, carbon graphitization and oxygen‐vacancy defects in HfO2/C@C core‐shell fibrous membranes. Synergistic multi‐loss effects optimize impedance matching to deliver −65.75 dB reflection loss and a 7.37 GHz effective bandwidth for flexible electromagnetic wave absorption.

Area and volume loss of the glaciers in the Ortles-Cevedale group (Eastern Italian Alps): controls and imbalance of the remaining glaciers [PDF]
The Cryosphere, 2013 Abstract. A widespread loss of glacier area and volume has been observed in the European Alps since the 1980s. In addition to differences among various regions of the Alps, different responses to climate change characterize neighboring glaciers within the same region.

Estimating the volume of glaciers in the Himalayan–Karakoram region using different methods [PDF]
The Cryosphere, 2014 Abstract. Ice volume estimates are crucial for assessing water reserves stored in glaciers. Due to its large glacier coverage, such estimates are of particular interest for the Himalayan–Karakoram (HK) region. In this study, different existing methodologies are used to estimate the ice reserves: three area–volume relations, one slope-dependent volume ...

Advanced Functional Materials, EarlyView.The APTES linker establishes a permanent interfacial dipole, reducing the work function of n‐GaN from 3.55 to 3.29 eV. This strengthens the built‐in electric field, significantly accelerating hole extraction to drive the oxygen evolution reaction (OER). Ultimately, this tailored charge‐separation architecture achieves a remarkable 4.78‐fold enhancement

The Mass Balance of the Kozelsky Glacier in Kamchatka for 1977–2022
Лëд и снег, 2023 The change in the volume of the Kozelsky Glacier in Kamchatka for the period 1977–2022 (1977–2015 and 2015–2022) was estimated using historical data and modern DEM. During this period, the area of the glacier did not change much.
