Method for Measuring the Laser Field and the Opacity of Spectral Lines in Plasmas

open access: yesPlasma, 2021
In experimental studies of laser-plasma interactions, the laser radiation can exist inside plasma regions where the electron density is below the critical density (“underdense” plasma), as well as at the surface of the critical density.

Results of Scanning Electron Microscopy of an Explanted Hydrophilic Acrylic IOL with Hydrophobic Coating

open access: yesOftalʹmologiâ, 2023
This article presents a clinical case of intraocular lens (IOL) removal due to surface degeneration 2 years after implantation. Explantation was performed resulting from clinically significant clouding of the IOL and decreased visual acuity.

The Shapes of Stellar Spectra

open access: yesAtoms, 2023
Stellar atmospheres separate the hot and dense stellar interiors from the emptiness of space. Radiation escapes from the outermost layers of a star, carrying direct physical information.

Photoionization and Opacity

open access: yesAtoms, 2023
Opacity determines radiation transport through material media. In a plasma source, the primary contributors to atomic opacity are bound–bound line transitions and bound-free photoionization into the continuum.

Finite-Horizon Shield for Path Planning Ensuring Safety/Co-Safety Specifications and Security Policies

open access: yesIEEE Access, 2023
With the development of network technology, security in path planning problems has attracted widespread attention. We consider a path planning problem in which a planner computes a finite path that satisfies a specification.
