ON HARMONICITY IN A DISC AND n-HARMONICITY [PDF]
Bulletin of the Korean Mathematical Society, 2010 Let ? 6 -0 be either a power bounded radial measure with compact support on the unit disc D with ?(D) = 1 such that there is a - > 0 so that |ˆ(s)| 6 1 for every s 2 §(-) \ {0,1}, or just a radial probability measure on D. Here, we provide a decomposition of the set X = {h 2 L 1 (D) | limn!1 h ⁄ ? n exists}.

Extreme–ultraviolet high–harmonic generation in liquids
Nature Communications, 2018 High–harmonic generation (HHG) in gases has been the main enabling technology of attosecond science since its discovery. Recently, HHG from solids has been demonstrated, opening a lively area of research. In contrast, harmonic generation from liquids has

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives Focal cortical dysplasia (FCD) is the most common etiology of drug‐resistant epilepsy in children. Focal to bilateral tonic–clonic seizures (FBTCS) mark a high risk of drug‐resistant epilepsy and involve thalamocortical circuitry in their generation and propagation.

On generalized $f$-harmonic morphisms [PDF]
, 2014 summary:In this paper, we study the characterization of generalized $f$-harmonic morphisms between Riemannian manifolds. We prove that a map between Riemannian manifolds is an $f$-harmonic morphism if and only if it is a horizontally weakly ...

Silica microfibres for broadband third harmonic generation
We report broadband third harmonic generation via intermodal phase matching in silica microfibres of several centimetres. A 5 dB conversion bandwidth exceeding 36 nm was recorded, with harmonic power detected over a 150 nm ...
