Neutron Diffraction Evidence for Stress‐Induced Melting of Ice During Deformation of D2O‐Ice Ih—Fluorite Mixtures

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Water ice is an important rock‐forming mineral, both on the Earth and on various extraterrestrial bodies. Naturally occurring ice is often “dirty”–an intimate mixture with harder mineral grains, which can have significant effects on the bulk properties of the aggregate. We have used neutron powder diffraction, with in situ triaxial deformation,

Results from the CERN pilot CLOUD experiment [PDF]

open access: yes, 2009
During a 4-week run in October–November 2006, a pilot experiment was performed at the CERN Proton Synchrotron in preparation for the Cosmics Leaving OUtdoor Droplets (CLOUD) experiment, whose aim is to study the possible influence of cosmic rays on ...

The AMS-02 Cosmic-Ray Deuteron Flux is Consistent with a Secondary Origin

open access: yesThe Astrophysical Journal Letters
The recent measurements of cosmic-ray (CR) deuteron fluxes by AMS-02 show that the rigidity dependence of deuterons is similar with that of protons but flatter than ^3 He, which has been attributed to the existence of primary deuterons with abundance ...

The High‐Latitude Workbox for the Ionosphere (HAWK‐I): A New Toolkit for Real‐Time Specification of the Arctic Ionosphere

open access: yesSpace Weather, Volume 24, Issue 9, September 2026.
Abstract The high‐latitude ionosphere exhibits rapid spatial and temporal variability during geomagnetically active periods, creating persistent challenges for accurate nowcasts. The High‐latitude Workbox for the Ionosphere (HAWK‐I) is a real‐time ionosphere nowcast and specification system designed for operational deployment to address these ...

Very high energy cosmic gamma rays from radio and x-ray pulsars [PDF]

open access: yes, 1987
This thesis is concerned with the detection of very high energy cosmic gamma-rays from isolated pulsars and X-ray binary sources using the atmospheric Cerenkov technique. A general introduction to gamma ray detection techniques is followed by adscription

Study of Flat-spectrum Radio Quasars and BL Lacertae Objects as Sources of Diffusive Ultrahigh-energy Cosmic Rays

open access: yesThe Astrophysical Journal
We examine whether flat-spectrum radio quasars (FSRQs) and BL Lac objects can act as plausible astrophysical sources of diffuse ultrahigh-energy cosmic rays (UHECRs).

Personalization and Fortification of In‐Space Manufactured Emulsified Beverages for Long‐Term Space Travel

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT The current trend of individualized food items (nutrient content and flavor) can be particularly valuable to support people's health and well‐being in isolated environments where access to fresh foods and diverse nutrition is difficult. At the same time, bioactive compounds and micronutrients can be employed to countermeasure any health ...

The Great Cosmic Silence: What Does the Fermi Paradox Tell About the Future of Humanity?

open access: yesGlobal Policy, Volume 17, Issue 4, Page 553-565, September 2026.
ABSTRACT This article examines how institutional time horizons shape the long‐term survival prospects of human technological civilisation. While research on global catastrophic and existential risks has expanded, the temporal structures of political‐economic institutions remain underexamined.
