All-fiber broadband spectral acousto-optic modulation of a tubular-lattice hollow-core optical fiber.

We demonstrate a broadband acousto-optic notch filter based on a tubular-lattice hollow-core fiber for the first time to our knowledge. The guided optical modes are modulated by acoustically induced dynamic long-period gratings along the fiber. The device is fabricated employing a short interaction length (7.

Can Leprosy Reaction States Mimic Symptoms of Fibromyalgia? A Cross-Sectional Analytical Study.

Leprosy causes significant pain in affected patients, especially those experiencing reactional states. Fibromyalgia is characterized by widespread pain and is often accompanied by fatigue. Confusion between the clinical manifestations of fibromyalgia and those of leprosy reactions is possible at the primary care level, the first contact with the health system in most cases.

Formation and Release of NO from Ruthenium Nitrosyl Ammine Complexes [Ru(NH)(NO)] in Aqueous Solution: A Theoretical Investigation.

In this article, density functional theory in conjunction with Monte Carlo statistical mechanical simulation was used to investigate the electronic structure, reduction potential, solvation, and solvent effects on the electronic spectra of nitrosyl ammine complexes using [Ru(NH)(NO)] as model compounds. In addition, ligand exchange reactions with solvent water molecules were also investigated. It is shown that the complexes are involved in strong hydrogen bonds in aqueous solution, with mean average energies of -13.
