Cosmic-ray hydrodynamics: Alfvén-wave regulated transport of cosmic rays [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2018
Star formation in galaxies appears to be self-regulated by energetic feedback processes. Among the most promising agents of feedback are cosmic rays (CRs), the relativistic ion population of interstellar and intergalactic plasmas.

Cosmic rays and space weather: effects on global climate change [PDF]

open access: yesAnnales Geophysicae, 2012
We consider possible effects of cosmic rays and some other space factors on the Earth's climate change. It is well known that the system of internal and external factors formatting the climate is very unstable; decreasing planetary temperature leads ...

Cosmic Ray Production in Supernovae [PDF]

open access: yesSupernovae, 2018
We give a brief review of the origin and acceleration of cosmic rays (CRs), emphasizing the production of CRs at different stages of supernova evolution by the first-order Fermi shock acceleration mechanism.

ARE THERE STRANGELETS IN COSMIC RAYS? [PDF]

open access: yesInternational Journal of Modern Physics A, 2005
Assuming that cosmic rays entering the Earth's atmosphere contain a small admixture of nuggets of strange quark matter in form of strangelets one can explain a number of apparently "strange" effects observed in different cosmic rays experiments.

An Indication of Anisotropy in Arrival Directions of Ultra-high-energy Cosmic Rays through Comparison to the Flux Pattern of Extragalactic Gamma-Ray Sources [PDF]

open access: yes, 2018
A new analysis of the data set from the Pierre Auger Observatory provides evidence for anisotropy in the arrival directions of ultra-high-energy cosmic rays on an intermediate angular scale, which is indicative of excess arrivals from strong, nearby ...

Overview on direct and indirect measurements of cosmic rays - Some thoughts on galactic cosmic rays and the knee [PDF]

open access: yesInt.J.Mod.Phys. A20 (2005) 6753-6764, 2005
An overview is given on results from direct and indirect measurements of galactic cosmic rays. Their implications on the contemporary understanding of the origin of cosmic rays and the knee in their energy spectrum are discussed.

ex vivo–in vivo comparison of drug penetration analysis by confocal Raman microspectroscopy and tape stripping

open access: yesExperimental Dermatology, Volume 31, Issue 12, Page 1908-1919, December 2022., 2022
Abstract When it comes to skin penetration analysis of a topically applied formulation, the number of suitable methods is limited, and they often lack in spatial resolution. In vivo studies are pivotal, especially in the approval of a new product, but high costs and ethical difficulties are limiting factors.
