The challenge of measuring the phase function of debris disks: Application to HR4796
(European Southern Observatory, 2020)
Context. Debris discs are valuable systems to study dust properties. Because they are optically thin at all wavelengths, we have direct access to the absorption and scattering properties of the dust grains. One very promising ...
The hyperfine structure of the lowest doublet states of the LiO2 isomers: a density-functional-theory assessment
(2010)
Density-functional-theory (DFT) calculations of the hyperfine coupling constants (HFCCs) are systematically reported for the lithium superoxide (LiO2) structural isomers in the doublet ground states, {\rm \tilde X} 2A2 and ...
Functional relationships between wood structure and vulnerability to xylem cavitation in races of Eucalyptus globulus differing in wood density
(Oxford University Press, 2018-02)
Wood density can be considered as a measure of the internal wood structure, and it is usually used as a proxy measure of other mechanical and functional traits. Eucalyptus is one of the most important commercial forestry ...
Experimental (electrochemistry) and theoretical (ab initio and density functional theory) studies of hydrogen and sulfide adsorption on palladium (100) surface.
(Soc Brasileira Quimica, 2001-07-01)
The adsorption of H And S2- species on Pd (100) has been studied with ab initio, density-functional calculations and electrochemical methods. A cluster of five Pd atoms with a frozen geometry described the surface. The ...
EEG functional connectivity metrics wPLI and wSMI account for distinct types of brain functional interactions.
The weighted Phase Lag Index (wPLI) and the weighted Symbolic Mutual Information (wSMI) represent two robust and widely used methods for MEG/EEG functional connectivity estimation. Interestingly, both methods have been ...

Effects of Side-Chain and Electron Exchange Correlation on the Band Structure of Perylene Diimide Liquid Crystals: A Density Functional Study
(AMER CHEMICAL SOC, 2009)
The structural and electronic properties of perylene diimide liquid crystal PPEEB are studied using ab initio methods based on the density functional theory (I)FT). Using available experimental crystallographic data as a ...
High density lipoprotein is an inappropiate substrate for hepatic lipase in postmenopausal women
(Elsevier Science, 2012-09)
Background HDL antiatherogenic effects would not only depend on its concentration but also on its biological quality. Hepatic lipase (HL) action on HDL acts in one of the last steps of reverse cholesterol transport. ...
