TL;DR: An old and forgotten algorithm that is revealed wider than recent schemes and able to improve contemporary schemes is revealed and proved to be optimal among first-order numerical schemes for image restoration.
Abstract: This paper deals with first-order numerical schemes for image restoration. These schemes rely on a duality-based algorithm proposed in 1979 by Bermudez and Moreno. This is an old and forgotten algorithm that is revealed wider than recent schemes (such as the Chambolle projection algorithm) and able to improve contemporary schemes. Total variation regularization and smoothed total variation regularization are investigated. Algorithms are presented for such regularizations in image restoration. We prove the convergence of all the proposed schemes. We illustrate our study with numerous numerical examples. We make some comparisons with a class of efficient algorithms (proved to be optimal among first-order numerical schemes) recently introduced by Y. Nesterov.

TL;DR: In this article, the authors demonstrate a computationally practical filtering strategy that could produce early-warning triggers before gravitational radiation from the final merger has arrived at the detectors, which could make it possible to observe the onset of electromagnetic emission from (CBC).
Abstract: Rapid detection of compact binary coalescence (CBC) with a network of advanced gravitational-wave detectors will offer a unique opportunity for multi-messenger astronomy. Prompt detection alerts for the astronomical community might make it possible to observe the onset of electromagnetic emission from (CBC). We demonstrate a computationally practical filtering strategy that could produce early-warning triggers before gravitational radiation from the final merger has arrived at the detectors.

TL;DR: A bridge between POD-based model order reduction techniques and the classical Newton/Krylov solvers is described, used to derive an efficient algorithm to correct, "on-the-fly", the reduced order modelling of highly nonlinear problems undergoing strong topological changes.

TL;DR: In this article, photochromic N-salicylidene-4-bromoaniline was obtained and studied for their second-order nonlinear optical properties.
Abstract: Noncentrosymmetric crystals of photochromic N-salicylidene-4-bromoaniline are obtained and studied for their second-order nonlinear optical properties. Second harmonic light is generated and can be seen by the naked eye. Moreover, photochromism in the bulk state yields totally reversible photoswitching of the second harmonic intensity.
