Oil Media on Paper: Investigating the Effect of Linseed Oils on Pure Cellulosic Paper Supports. A Research Matter of Damage Assessment

open access: yesAnalytica, 2022
Oil media on paper, such as oil paintings, sketches, prints, and books, occasionally present problems associated with the effect of oil medium on the paper support, raising a composite matter of condition assessment as it depends on several factors.

Structure Calculations in Nd III and U III Relevant for Kilonovae Modelling

open access: yesAtoms, 2022
The detection of gravitational waves and electromagnetic signals from the neutron star merger GW170817 has provided evidence that these astrophysical events are sites where the r-process nucleosynthesis operates.

The Opacity of Backbones

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2017
A backbone of a boolean formula F is a collection S of its variables for which there is a unique partial assignment aS such that F[aS] is satisfiable (Monasson et al. 1999; Williams, Gomes, and Selman 2003).  This paper studies the nontransparency of backbones.

Empirical Line Lists in the ExoMol Database

open access: yesAtoms, 2020
The ExoMol database aims to provide comprehensive molecular line lists for exoplanetary and other hot atmospheres. The data are expanded by inclusion of empirically derived line lists taken from the literature for a series of diatomic molecules, namely ...

Against Opacity [PDF]

open access: yesResearch on Language and Computation, 2007
Compositionality often presupposes a notion of opacity in that the combination of the meanings M and N of the subconstituents of a constituent C into the meaning of C must be blind to the inner structure of M and N. However, for cases where there is no direct 1-1 mapping between (surface) syntactic and semantic structure, opacity seems to be too strong

Atomic opacities [PDF]

open access: yesInternational Astronomical Union Colloquium, 1994
Let Iv(r, θ) be the intensity of radiation of frequency v, at a distance r from the centre of a star and in a direction making an angle θ to the outward normal. In a plane-parallel approximation the equation of radiative transfer is where 𝛋v is the opacity and jv the emissivity. The net outward flux of radiant energy is

Effect of Y2O3 content on the mechanical and optical properties of zirconia-based dental ceramics [PDF]

open access: yesCerâmica
The present work aims to identify variations in the mechanical and optical properties of samples produced from ZrO2 powders containing different Y2O3 contents (3Y-TZP, 4Y-PSZ, and 5Y-PSZ) intended for applications such as dental prostheses.

Contemporary art and financialization: Two approaches

open access: yesFinance and Society, 2016
This essay identifies two approaches to theorizing the relationship between financialization and contemporary art. The first departs from an analysis of how market logics in non-financial spheres are being transformed to facilitate financial circulation;
