Compact Plasma-Based Soft X-Ray Lasers
This paper reviews the major accomplishments in the demonstration of plasmabased soft x-ray lasers in 2009. Advances in shaping the plasma density and increasing the pump power have enabled the engineering of table-top laser systems operating at ...

Robust Evaluation of Ultraviolet-C Sensitivity for SARS-CoV-2 and Surrogate Coronaviruses
UV light, more specifically UV-C light at a wavelength of 254 nm, is often used to disinfect surfaces, air, and liquids. In early 2020, at the cusp of the COVID-19 pandemic, UV light was identified as an efficient means of eliminating coronaviruses ...

Intensities of incident and transmitted ultraviolet-a rays through gafchromic films
Gafchromic films have been applied to X-ray dosimetry in diagnostic radiology. To correct nonuniformity errors in Gafchromic films, X-rays in the double-exposure technique can be replaced with ultraviolet (UV)-A rays.

Ultraviolet properties of f(R)-Gravity [PDF]
We discuss the existence and properties of a nontrivial fixed point in f(R)-gravity, where f is a polynomial of order up to six. Within this seven-parameter class of theories, the fixed point has three ultraviolet-attractive and four ultraviolet-repulsive directions; this brings further support to the hypothesis that gravity is nonperturbatively ...

Chlorogenic acid in preventing and curing ultraviolet-induced damage in human skin fibroblast as an antiaging cell model [PDF]
Continuous ultraviolet (UV) irradiation stimulates the over-production of reactive oxygen species (ROS) to cause degenerative diseases. Chlorogenic acid (CA) is found as plants antioxidant that promises medicinal effects.

Large-order Behaviour due to Ultraviolet Renormalons in QCD [PDF]
Ultraviolet renormalons, contrary to their infrared counterparts, lead to a universal contribution to the large-order behaviour of perturbative expansions in QCD. In this letter, we determine nature of the leading ultraviolet renormalon singularity for the inclusive hadroproduction cross section in $e^+ e^-$ annihilation, for hadronic $\tau$ decays and

Spectral Behaviour and Flaring Activity of II Peg in the Ultraviolet [PDF]
We have investigated the spectral behaviour of II Peg binary system in the ultraviolet band by using International Ultraviolet Explorer observations over fifteen years. The ultraviolet observations show indication of flare activity in the chromosphere and transition region with their enhanced spectral lines.
