Shape of spectrum of galactic cosmic ray intensity fluctuations

open access: yesSolar-Terrestrial Physics, 2022
The impact of solar wind plasma on fluxes of galactic cosmic rays (CR) penetrating from the outside into the heliosphere with energies above ~1 GeV leads to temporal variations in the CR intensity in a wide frequency range.

Cis–Trans Rotational Isomerism of Formic Acid, Sulfur, and Selenium Analogues and Their Dimers: Chemical Kinetics Under Interstellar Conditions

open access: yesInternational Journal of Chemical Kinetics, Volume 58, Issue 12, Page 1136-1145, December 2026.
ABSTRACT We present chemical kinetic rate constants for the cis to trans isomerisation or rotamerization of monomeric seleno‐, thio‐, and formic acids and that of three of their dimeric species, based on variational transition state theory and multidimensional tunneling calculations in the gas‐phase, from 10 K to 300 K. These provide, firstly, reliable

Searches for Neutrinos from Large High Altitude Air Shower Observatory Ultra-high-energy γ-Ray Sources Using the IceCube Neutrino Observatory

open access: yesThe Astrophysical Journal Letters, 2023
Galactic PeV cosmic-ray accelerators (PeVatrons) are Galactic sources theorized to accelerate cosmic rays up to PeV in energy. The accelerated cosmic rays are expected to interact hadronically with nearby ambient gas or the interstellar medium, resulting

Poly(Alkoxythiophene) Rod‐Coil Block Copolymers for Organic Electrochemical Transistors

open access: yesAdvanced Materials, Volume 38, Issue 61, 2 November 2026.
We present the first synthesis of poly(3‐alkoxythiophene) rod‐coil block copolymers as a new architecture for OMIECs. Incorporating PEG and PLLA coils can enhance device performance beyond the homopolymer. The figure‐of‐merit depends uniquely on coil length.

Cosmic Rays in Galactic and Extragalactic Magnetic Fields [PDF]

open access: yes, 2011
We briefly review sources of cosmic rays, their composition and spectra as well as their propagation in the galactic and extragalactic magnetic fields, both regular and fluctuating. A special attention is paid to the recent results of the X-ray and gamma-

Simulating Inner Radiation Belt Electron Transport and Low‐Latitude Precipitation Driven by Disturbance Electric Fields

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract Increasing attention has been given to large‐scale disturbance electric fields in the inner radiation belt as a driver of drift‐periodic zebra stripe formations. Such disturbance electric fields have also been discussed as a possible driving mechanism of electron precipitation, transporting electrons below the inner belt and into the ...

Influence of Space Weather on Single Event Effects in Aviation When Employing Modern Commercial Sub‐100 nm Electronic Devices

open access: yesSpace Weather, Volume 24, Issue 11, November 2026.
Abstract During November 2025 thousands of commercial aircraft (Airbus A320s) had to be grounded due to the risk of ionizing radiation effects on the avionics system. Safety‐critical systems continue to use modern commercial devices, and therefore an understanding of their responses within enhanced radiation environments is crucial to ensure reliable ...

Research on Cosmic Rays and Their Impact on Human Activities

open access: yes, 2022
The galactic cosmic–ray spectrum extends over 14 orders of magnitudes in energy and about 12 orders of magnitude in intensity, and it can be studied using two different methods: via the “direct detection” of the primary cosmic rays in space or at high ...

The Problem of Psychonomic Harmony

open access: yesPhilosophy and Phenomenological Research, Volume 113, Issue 3, Page 529-542, November 2026.
ABSTRACT The problem of nomological harmony is the problem of explaining why the laws of nature match or apply to the states of the universe in a way that results in temporal evolution. The problem of psychophysical harmony is the problem of explaining why phenomenal states are paired with physical states and other phenomenal states in surprisingly ...

GeV-TeV Galactic cosmic rays

open access: yes, 2013
International audienceThis short review aims at presenting the way we currently understand, model, and constrain the transport of cosmic rays in the GeV-TeV energy domain. This is a research field per se, but is also an important tool e.g. to improve our
