Direct Evidence of Magnetic Reconnection Onset via the Tearing Instability [PDF]
Frontiers in Astronomy and Space Sciences, 2022 Magnetic reconnection is a sporadic process responsible for energy release in space and laboratory plasmas. It is believed that the tearing mode instability may be responsible for the onset of reconnection in the magnetotail.

A review on hot tearing of magnesium alloys
Journal of Magnesium and Alloys, 2016 Hot tearing is often a major casting defect in magnesium alloys and has a significant impact on the quality of their casting products. Hot tearing of magnesium alloys is a complex solidification phenomenon which is still not fully understood, it is of ...

Deciphering the Action of Perfluorohexyloctane Eye Drops to Reduce Ocular Discomfort and Pain
Frontiers in Medicine, 2021 Perfluorohexyloctane (F6H8) eyedrops have been recently introduced in Europe as a product to treat dry eye disease, based on its ability to reduce tear film instability in Meibomian gland dysfunction and evaporative dry eye disease, although its ...

Hot tearing behavior of NZ30K Mg alloy under progressive solidification [PDF]
China Foundry, 2021 Progressive solidification is usually considered an effective strategy to reduce the hot tearing susceptibility of a cast component. In this study, special constrained plate castings with progressive changes in cross-section were designed, which enabled ...

Parameter Estimation for Mixed-Mechanism Tear Film Thinning [PDF]
Bulletin of Mathematical Biology (2021), 2020 Etiologies of tear breakup include evaporation-driven, divergent flow-driven, and a combination of these two. A mathematical model incorporating evaporation and lipid-driven tangential flow is fit to fluorescence imaging data. The lipid-driven motion is hypothesized to be caused by localized excess lipid, or "globs." Tear breakup quantities such as ...
