The influence of cosmic-rays on the magnetorotational instability [PDF]
, 2011 We present a linear perturbation analysis of the magnetorotational instability in the presence of the cosmic rays. Dynamical effects of the cosmic rays are considered by a fluid description and the diffusion of cosmic rays is only along the magnetic field lines.

Supernova Remnants as the Sources of Galactic Cosmic Rays [PDF]
, 2012 The origin of cosmic rays holds still many mysteries hundred years after they were first discovered. Supernova remnants have for long been the most likely sources of Galactic cosmic rays.

, 2010 Supernova remnants are thought to be the dominant source of Galactic cosmic rays. This requires that at least 5% of the available energy is transferred to cosmic rays, implying a high cosmic-ray pressure downstream of supernova remnant shocks.

Nuclear Physics Meets the Sources of the Ultra-High Energy Cosmic Rays [PDF]
, 2016 The determination of the injection composition of cosmic ray nuclei within astrophysical sources requires sufficiently accurate descriptions of the source physics and the propagation - apart from controlling astrophysical uncertainties.

Hidden Cosmic-Ray Accelerators as an Origin of TeV-PeV Cosmic Neutrinos. [PDF]
Physical Review Letters, 2015 The latest IceCube data suggest that the all-flavor cosmic neutrino flux may be as large as 10^{-7} GeV cm^{-2} s^{-1} sr^{-1} around 30 TeV. We show that, if sources of the TeV-PeV neutrinos are transparent to γ rays with respect to two-photon ...

Advanced Energy Materials, EarlyView.This work presents a tailored solid‐state route to enhance DRX fluorination and electrochemical performance. Using unconventional precursors, Li6MnO4, MnF2, and TiO2, prevents Mn‐based intermediates, which do not accommodate fluorines, enabling the formation of highly fluorinated DRX with a composition of Li1.23Mn0.40Ti0.37O2−yFy (y = 0.29–0.34 ...

, 2008 Supernova remnants are likely to be the accelerators of the galactic cosmic rays. Assuming the correctness of this hypothesis, we develop a method to extract the parent cosmic ray spectrum from the VHE gamma ray flux emitted by supernova remnants (and ...

Swarm‐Optimized ZnO/CdS/CIGS/GaAs Solar Cell for Enhanced Efficiency and Thermal Resilience
Advanced Energy and Sustainability Research, EarlyView.This article addresses the problem of optimizing the efficiency and thermal resilience of ZnO/CdS/CIGS solar cells, which are promising but still face challenges in maximizing performance under high‐temperature conditions and concentrated sunlight. The main issue is enhancing the efficiency of these cells while also ensuring that they can withstand the

Space weather and dangerous phenomena on the Earth: principles of great geomagnetic storms forcasting by online cosmic ray data [PDF]
Annales Geophysicae, 2005 According to NOAA space weather scales, geomagnetic storms of scales G5 (3-h index of geomagnetic activity Kp=9), G4 (Kp=8) and G3 (Kp=7) are dangerous for satellites, aircrafts, and even for technology on the ground (influence on power systems, on ...
