Sources of primary cosmic rays

open access: yes, 2023
In the paper, a comparative primary cosmic rays (PCR) comparative analysis by $E_0$ and the spectra of variable stars by periods is carried out in order to establish the causes of irregularities in the spectrum of PCR by $E_0$. The study was performed using the public database of the KASCADE-Grande experiment and GCVS and ZTF variable star catalogues ...

Contrasting Models of Deification: The Technological Anthropology of the AI Age and the Theological Anthropology of Early Christianity

open access: yesInternational Journal of Systematic Theology, EarlyView.
Abstract Ancient ideas about human transformation and divinization have resurfaced in our cultural moment. Artificial intelligence and biotechnology are raising afresh questions about what it means to be human and divine. The Oxford Handbook of Deification has arrived on the scene as its subject matter has splashed out of theological discourse into the

Noble gases and nitrogen in material from asteroid Bennu

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Human Destiny and the Natural Law in St Maximus the Confessor: A Contribution to Orthodox Christian Humanism

open access: yesModern Theology, EarlyView.
Abstract Orthodox Christian theology in general prides itself on bearing the mantle of patristic thought. Orthodox theological anthropology is no different, often drawing on Greek patristic sources in presenting its vision of the human being. Yet Orthodox anthropology can also broadly be categorized as personalist in ways that are not necessarily so ...

Photodegradation of commercial insect repellents containing DEET and IR‐3535 under ultraviolet light associated or not with chemical ultraviolet filters evaluated by Raman spectroscopy

open access: yesPhotochemistry and Photobiology, EarlyView.
This study evaluated the photodegradation of commercial insect repellents containing DEET and IR‐3535 under UV‐A and UV‐B irradiation using Raman spectroscopy. Pure DEET and IR‐3535 showed intrinsic photostability, whereas DEET diluted in ethanol and a commercial DEET‐based formulation exhibited significant spectral changes after UV exposure.

Low‐dose X‐ray radiation induces an adaptive response: A potential countermeasure to galactic cosmic radiation exposure

open access: yesExperimental Physiology, EarlyView.
Abstract Space exploration involves many dangers including galactic cosmic radiation (GCR). This class of radiation includes high‐energy protons and heavy ionizing ions. NASA has defined GCR as a carcinogenic risk for long‐duration space missions. To date, no clear strategy has been developed to counter chronic GCR exposure.

UHECRs Propagation and Their Multimessengers: Upper Limits and the Impact of the Extragalactic Magnetic Field

open access: yesThe Astrophysical Journal
The detection of high-energy astrophysical multimessengers establishes a connection between ultra-high-energy cosmic rays (UHECRs) and powerful cosmic accelerators.

The cosmic-ray source composition

open access: yesThe Astrophysical Journal, 1986
The cosmic-ray source composition is shown to be related to the observed cosmic-ray abundances by a set of linear equations which are valid for either ad hoc path length distributions or quantitative solutions of galactic propagation models. In the limit of no ionization energy loss, this method is exact for all path length distributions and can ...
