Ultraviolet Radiation From a Plant Perspective: The Plant-Microorganism Context

Frontiers in Plant Science, 2020
Ultraviolet (UV) radiation directly affects plants and microorganisms, but also alters the species-specific interactions between them. The distinct bands of UV radiation, UV-A, UV-B, and UV-C have different effects on plants and their associated ...

A Giant Planet Undergoing Extreme-Ultraviolet Irradiation By Its Hot Massive-Star Host [PDF]

, 2017
The amount of ultraviolet irradiation and ablation experienced by a planet depends strongly on the temperature of its host star. Of the thousands of extrasolar planets now known, only six have been found that transit hot, A-type stars (with temperatures ...

On the QCD corrections to the charged Higgs decay of a heavy quark

, 1992
Using dimensional regularization for both infrared and ultraviolet divergences, we confirm that the QCD corrections to the decay width $\Gamma(t\to H^+b)$ are equal to those to $\Gamma(t\to W^+b)$ in the limit of a large $t$ quark mass.Comment: 6 pages ...
