Comprehensive two-dimensional river ice model based on boundary-fitted coordinate transformation method

open access: yesWater Science and Engineering, 2014
River ice is a natural phenomenon in cold regions, influenced by meteorology, geomorphology, and hydraulic conditions. River ice processes involve complex interactions between hydrodynamic, mechanical, and thermal processes, and they are also influenced ...

Monitoring the Ice Phenology of Qinghai Lake from 1980 to 2018 Using Multisource Remote Sensing Data and Google Earth Engine

open access: yesRemote Sensing, 2020
Lake ice, one of the most direct lake physical characteristics affected by climate change, can reflect small-scale environmental changes caused by the atmosphere and hydrology, as well as large-scale climate changes such as global warming.

Evolution From Past to Future Conditions of Fast Ice Coverage in James Bay

open access: yesFrontiers in Earth Science, 2019
Fast ice is often used by coastal communities in the James Bay area for transportation in winter using snowmobiles. Therefore, the extent of fast ice along the James Bay coastline is important for land use and any changes to these extents may have ...

Scalable anisotropic cooling aerogels by additive freeze-casting

open access: yesNature Communications, 2022
Scaling up anisotropic freeze-casting processes can be challenging due to the temperature gradient farther from the cold source. Here, authors report an additive freeze-casting technique able to produce large-scale aerogel panels and demonstrate it ...

Cost-effectiveness of freeze-all policy – A retrospective study based upon the outcome of cumulative live births

open access: yesTaiwanese Journal of Obstetrics & Gynecology, 2021
Object: We have previously reported that cumulative live birth rates (CLBRs) are higher in the freeze-all group compared with controls (64.3% vs. 45.8%, p = 0.001).

Selective Exclusion of Aromatic Organic Carbon During Lake Ice Formation

open access: yesGeophysical Research Letters, 2023
Earth's lakes at northern latitudes are mostly ice‐covered in winter. When lake water freezes, some organic matter dissolved in the water is excluded from the ice.
