Atmospheric Cerenkov astronomy of cataclysmic variables & other potential gamma ray sources [PDF]

open access: yes, 1993
Recent developments in the application of the atmospheric Cerenkov technique to 7-ray astronomy are reviewed here. These include new methods of signal to noise enhancement and the increasing diversity of stellar systems positively identified as Very High

Evaluating the Efficacy of Sunscreen Formulas in Reducing UV Filter Permeation Into the Stratum Corneum via In Vivo Confocal Raman Spectroscopy: Insights and Applications for Practical Suncare Product Design

open access: yesPhotodermatology, Photoimmunology &Photomedicine, Volume 42, Issue 5, September 2026.
ABSTRACT Aims The transdermal permeation of UV filters has long been a concern among consumers and researchers. Among them, the permeation of small‐molecule UV filters such as homosalate (HMS) (molecular weight < 500 Da) and the regulatory effects of formulation components on its permeation have not been fully investigated.

Explainable Machine Learning Classification of Chandra X-Ray Sources: SHAP Analysis of Multiwavelength Features

open access: yesThe Astrophysical Journal
Extensive astronomical surveys, like those conducted with the Chandra X-ray Observatory, detect hundreds of thousands of unidentified cosmic sources. Machine learning (ML) methods offer an efficient, probabilistic approach to classifying them, which can ...

Women in space: A review of known physiological adaptations and health perspectives

open access: yesExperimental Physiology, Volume 111, Issue 9, Page 3944-3967, 1 September 2026.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Cosmic ray-induced high energy gamma-ray emission: a background for WIMP annihilation and massive relic particle models of UHE CR

open access: yes, 2001
© Copernicus Gesellschaft 2001The possible discovery of a diffuse galactic halo in GeV gamma-rays has led to several possible dark matter explanations.

TeV astronomy of millisecond pulsars [PDF]

open access: yes, 1991
This thesis is concerned with the detection of pulsed TeV γ-rays from millisecond pulsars. These stars appear to include some very efficient producers of high energy particles, but the mechanisms by which they produce TeV γ-rays are still a matter of ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, Volume 111, Issue 9, Page 4015-4040, 1 September 2026.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Tackling aging and chronic disease: How space exploration and the ‘chameleon effect’ of pharmaceuticals can lead the way

open access: yesExperimental Physiology, Volume 111, Issue 9, Page 4064-4072, 1 September 2026.
Abstract A common misconception surrounding space exploration is that humanity's pursuit of interplanetary travel, such as missions to Mars, is an escape from Earth. In reality, this endeavour offers an invaluable opportunity to address critical biomedical challenges here at home.

Deep-Learning-Based Cosmic-Ray Mass Reconstruction Using the Water-Cherenkov and Scintillation Detectors of AugerPrime

open access: yes
At the highest energies, cosmic rays can be detected only indirectly by the extensive air showers they create upon interaction with the Earth’s atmosphere.
