The spatial–temporal total friction coefficient of the fault viewed from the perspective of seismo-electromagnetic theory [PDF]

Natural Hazards and Earth System Sciences, 2020
Recently, it has been shown theoretically how the lithospheric stress changes could be linked with magnetic anomalies, frequencies, spatial distribution and the magnetic-moment magnitude relation using the electrification of microfractures in the ...

Nuclear Physics Meets the Sources of the Ultra-High Energy Cosmic Rays

Scientific Reports, 2017
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.

Characterization of Thermoluminescent Dosimeters for Neutron Dosimetry at High Altitudes

Sensors, 2022
Neutrons constitute a significant component of the secondary cosmic rays and are one of the most important contributors to natural cosmic ray radiation background dose. The study of the cosmic ray neutrons’ contribution to the dose equivalent received by

Transforming DIY Geiger Counter Kits into Muon Detectors for Education and Scientific Exploration

Particles
Any Geiger counter can be used as an effective cosmic ray detector on its own. In fact, it is known that even in the absence of a radioactive source, the instrument detects what is known as background radiation, which consists of various types of ...

Analytical Model for Estimating Terrestrial Cosmic Ray Fluxes Nearly Anytime and Anywhere in the World: Extension of PARMA/EXPACS.

PLoS ONE, 2015
By extending our previously established model, here we present a new model called "PHITS-based Analytical Radiation Model in the Atmosphere (PARMA) version 3.0," which can instantaneously estimate terrestrial cosmic ray fluxes of neutrons, protons, ions ...
