Natural Agents for Preventing Skin Damage Induced by Visible Light: A Systematic Review of Preclinical and Clinical Evidence

open access: yesPhotodermatology, Photoimmunology &Photomedicine, Volume 42, Issue 5, September 2026.
ABSTRACT Background/Purpose Visible light (VL), and particularly high‐energy visible light (HEVL), reaching Earth's surface has emerged as a relevant contributor to skin damage. VL has been implicated in oxidative stress, inflammation, pigmentation disorders, and photoaging, especially in individuals with darker skin phototypes.

Hybrid SDF-HDF cluster-based fusion scheme for cooperative spectrum sensing in cognitive radio networks

open access: yes, 2010
In cognitive radio networks, cooperative spectrum sensing schemes are proposed to improve the performance of detecting licensees by secondary users. Commonly, the cooperative sensing can be realized by means of hard decision fusion (HDF) or soft decision

A GEO‐LEO Imager Data Set for Characterizing Rapid Changes of Global Aerosol Properties

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Aerosols, the ubiquitous small particulates in our atmosphere, have climate, air quality, and/or other impacts far from their original sources. The Dark Target Algorithm (DTA), originally developed for retrieving aerosol properties from satellite imagers in Low‐Earth Orbit (LEO), has been ported to imagers in Geostationary (GEO) orbit. Using a

Are the HDF Galaxy Counts Whole Numbers?

open access: yes, 2007
The Hubble Deep Field 2 (HDF) offers the best view to date of the optical sky at faint magnitudes and small angular scales. Early reports suggested that faint source counts continue to rise to the completeness limit of the data.
