CONGENITAL OPACITY OF THE CORNEA. [PDF]

open access: greenJAMA: The Journal of the American Medical Association, 1898
The recent articles by Tepljaschin ( Arch. Ophth. , Vol. xxvi, p. 74) and by Barbacheff (review in Ophth. Rec. , Vol. vi, p. 88) have stimulated interest in the rare anomalies of corneal transparency of congenital origin. The point of practical interest is to determine whether such a case is due to arrested development or to an inflammatory process ...

Quantifying Opacity [PDF]

open access: yes2010 Seventh International Conference on the Quantitative Evaluation of Systems, 2010
Opacity is a general language-theoretic framework in which several security properties of a system can be expressed. Its parameters are a predicate, given as a subset of runs of the system, and an observation function, from the set of runs into a set of observables.

News from the opacity consortium OPAC [PDF]

open access: yesEPJ Web of Conferences, 2013
The international OPAC consortium (see list below) was formed three years ago. It is composed of astrophysicists, plasma physicists and experimentalists from different laboratoriesb. This consortium examines specific opacity calculations used in stellar physics.

The Metaphysics of Opacity

open access: yesPhilosophers' Imprint, 2023
This paper examines the logical and metaphysical consequences of denying Leibniz's Law, the principle that if t1= t2, then φ(t1) if and only if φ(t2). Recently, Caie, Goodman, and Lederman (2020) and Bacon and Russell (2019) have proposed sophisticated logical systems permitting violations of Leibniz's Law.

Thermochromic and opacity behaviors in vanadium dioxide nanofilms: a theoretical study

open access: yesMaterials Research Express, 2022
Vanadium dioxide nanofilms are one of the most essential materials in electronic applications like smart windows. Therefore, studying and understanding the optical properties of such films is crucial to modify the parameters that control these properties.

Overapplication opacity in phonological acquisition

open access: yesNordlyd: Tromsø University Working Papers on Language & Linguistics, 2013
Phonological opacity is a challenge for parallel OT, which does not allow for intermediate levels of representation. Several modifications of the theory have been proposed over the years to incorporate opacity, all of them falling short of accounting for

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.

The Variable Rotation Measure Distribution in 3C 273 on Parsec Scales

open access: yesGalaxies, 2018
We briefly review how opacity affects the observed polarization in synchrotron emitting jets. We show some new multi-frequency observations of 3C 273 made with the VLBA in 1999–2000, which add significantly to the available rotation measure (RM ...

A reanalysis of abstract contrasts and opacity in Bondu-so tongue root harmony

open access: yesGlossa, 2020
This paper explores a number of controversial consequences of previous abstract analyses of Bondu-so (Dogon) vowels and vowel harmony, particularly for the explanation of phonological opacity.
