Application of physics-informed neural networks to inverse problems in unsaturated groundwater flow

Georisk: Assessment and Management of Risk for Engineered Systems and Geohazards, 2021
This paper investigates the application of Physics-Informed Neural Networks (PINNs) to inverse problems in unsaturated groundwater flow. PINNs are applied to the types of unsaturated groundwater flow problems modelled with the Richards partial ...

How cholesterol stiffens unsaturated lipid membranes

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Cholesterol regulates critical cell functions, including lysis, viral budding, and antibiotic resistance, by modifying the bending rigidity of cell membranes; i.e., the ability of membranes to bend or withstand mechanical stresses.

Plant Unsaturated Fatty Acids: Biosynthesis and Regulation

Frontiers in Plant Science, 2020
In most plants, major unsaturated fatty acids (UFAs) are three C18 species, namely, oleic (18:1), linoleic (18:2), and α-linolenic (18:3) acids. These simple compounds play multiple crucial roles in planta and are also important economic traits of oil ...

In vitro esterification of cholesterol by pancreatic juice and by acetone powder extracts of small intestine: the effect of unsaturated fatty acids upon esterification with saturated fatty acids

Journal of Lipid Research, 1965
The esterification of cholesterol by rat pancreatic juice and by extracts of acetone powders of rat small intestine was studied with palmitic, stearic, oleic, linoleic, and linolenic acids.

Soil–water characteristic curve of unsaturated collapsible soils

Journal of the Mechanical Behavior of Materials, 2023
Collapsible soils are almost found in unsaturated states and involved significant engineering problems. Geotechnical challenges of such soils are represented by the hydro-mechanical behaviour during wetting–drying cycles due to the humidity and climate ...

Metal Organic Framework with Coordinatively Unsaturated Sites as Efficient Fenton-like Catalyst for Enhanced Degradation of Sulfamethazine.

Environmental Science and Technology, 2018
A novel Fenton-like catalyst, metal organic framework MIL-100(Fe) with FeII/FeIII mixed-valence coordinatively unsaturated iron center (CUS-MIL-100(Fe)), was synthesized, characterized, and used for the degradation of sulfamethazine (SMT).
