INCIDENCE OF POSTERIOR CAPSULAR OPACIFICATION AFTER UNEVENTFUL CATARACT SURGERY IN PATIENTS ON HEMODIALYSIS

open access: yesSanamed, 2019
Purpose: To evaluate the incidence of posterior capsular opacification after cataract surgery in patients on hemodialysis. Patients and Methods: Fifty patients on hemodialysis undergoing cataract surgery and 50 patients undergoing cataract surgery in a ...

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.

An Empirical Determination of the Intergalactic Background Light Using NIR Deep Galaxy Survey Data out to 5 microns and the Gamma-ray Opacity of the Universe [PDF]

open access: yes, 2014
We extend our previous model-independent determination of the intergalactic background light (IBL), based purely on galaxy survey data, out to a wavelength of 5 microns.

Verification of Opacity Under a K-Delay Orwellian Observation Mechanism

open access: yesMathematics
Opacity, an important property of the information flow in discrete-event systems (DESs), characterizes whether the secret information in a system is ambiguous to a passive observer (called an intruder).

Transforming opacity verification to nonblocking verification in modular systems

open access: yes, 2019
We consider the verification of current-state and K-step opacity for systems modeled as interacting non-deterministic finite-state automata. We describe a new methodology for compositional opacity verification that employs abstraction, in the form of a ...

Electron neutrino opacity in magnetised media [PDF]

open access: yes, 1997
We study the effects of strong magnetic fields ($B> 10^{13}$~G) in the cross section for $\nu_e n\to p e$ scattering in the presence of a degenerate electron background.

Neutrino Opacity I. Neutrino-Lepton Scattering [PDF]

open access: yes, 1964
The contribution of neutrino-lepton scattering to the total neutrino opacity of matter is investigated; it is found that, contrary to previous beliefs, neutrino scattering dominates the neutrino opacity for many astrophysically important conditions.

Picturing the world—cinematic globalization in the deserts of Babel

open access: yesJournal of Aesthetics & Culture, 2013
Globalization remains a challenge for the art of cinema. No art form is more suited to the task of showing clashes between cultures and the internal conflicts of a society, but as films are both narratively and physically dependent on locations— ...
