Artificial intelligence-based refractive error prediction and EVO-implantable collamer lens power calculation for myopia correction

Eye and Vision, 2023
Background Implantable collamer lens (ICL) has been widely accepted for its excellent visual outcomes for myopia correction. It is a new challenge in phakic IOL power calculation, especially for those with low and moderate myopia.

Algorithm for selecting patients for cochlear implantation. Lecture for physicians

Consilium Medicum, 2023
At the present stage in the world there are many methods for restoring hearing in humans, but, unfortunately, not all methods are effective for high-grade hearing loss or deafness.

Wormholes Immersed in Rotating Matter

, 2017
We demonstrate that rotating matter sets the throat of an Ellis wormhole into rotation, allowing for wormholes which possess full reflection symmetry with respect to the two asymptotically flat spacetime regions.

Five-year outcomes of EVO implantable collamer lens implantation for the correction of high myopia and super high myopia

Eye and Vision, 2021
Background To evaluate the long-term safety, efficacy, predictability, and stability of implantable collamer lens with a central hole (EVO ICL) implantation for correcting high myopia (HM) and super high myopia (SHM).

A clinical case of a patient with an anomaly in the development of the inner ear and refractory stimulation of the facial nerve after a coronavirus infection and meningitis

Consilium Medicum, 2023
Background. Thanks to the development of technology and new surgical approaches, it has become possible to perform cochlear implantation (CI) in patients with malformations of the inner ear.

Simulation and static measurement of the gas volume fraction in a separated flow model using a Conductance Multiphase Venturi Meter (CMVM) [PDF]

, 2008
The assumption of equal mixture densities at the inlet and the throat of the Venturi is only valid in a homogenous flow. This assumption is no longer valid for a separated flow and therefore, the measurement of the gas volume fraction at the throat must ...

Inflation from Warped Space

, 2005
A long period of inflation can be triggered when the inflaton is held up on the top of a steep potential by the infrared end of a warped space. We first study the field theory description of such a model.

On Power Law Inflation in DBI Models [PDF]

, 2007
Inflationary models in string theory which identify the inflaton with an open string modulus lead to effective field theories with non-canonical kinetic terms: Dirac-Born-Infeld scalar field theories.
