EFFECT OF SOLAR ECLIPSES ON RADIOWAVE PROPAGATION IN THE TROPOSPHERE [PDF]

Радиофизика и электроника, 2015
Energy of solar eclipses significantly influences the variation of geophysical fields and leads to a change of processes in the subsystems of the Earth and to disturbance of the existing interactions between them. Observations of each solar eclipse allow

Essential Infantile Esotropia: A Course of Treatment From Our Experience

Frontiers in Pediatrics, 2021
Background: Essential infantile esotropia (EIE) is the most common type of childhood esotropia. Although its classical approach is surgical, less invasive techniques have been proposed as an adjunct or alternative to traditional surgery.

Refraction in exoplanet atmospheres: Photometric signatures, implications for transmission spectroscopy, and search in Kepler data

, 2017
Refraction deflects photons that pass through atmospheres, which affects transit light curves. Refraction thus provides an avenue to probe physical properties of exoplanet atmospheres and to constrain the presence of clouds and hazes.

Nonlinear interfaces: intrinsically nonparaxial regimes and effects [PDF]

, 2009
The behaviour of optical solitons at planar nonlinear boundaries is a problem rich in intrinsically nonparaxial regimes that cannot be fully addressed by theories based on the nonlinear Schrödinger equation.

Refraction of dispersive shock waves [PDF]

, 2012
We study a dispersive counterpart of the classical gas dynamics problem of the interaction of a shock wave with a counter-propagating simple rarefaction wave often referred to as the shock wave refraction.

Implications of Atmospheric Differential Refraction for Adaptive Optics Observations [PDF]

, 2002
Many adaptive optics systems operate by measuring the distortion of the wavefront in one wavelength range and performing the scientific observations in a second, different wavelength range.

Refractive surgery

The Lancet, 2019
Refractive surgery has evolved beyond laser refractive techniques over the past decade. Laser refractive surgery procedures (such as laser in-situ keratomileusis), surface ablation techniques (such as laser epithelial keratomileusis), and photorefractive keratectomy have now been established as fairly safe procedures that produce excellent visual ...
