Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Jupiters radiation belts and their effects on spacecraft [PDF]

open access: yes, 1974
The effects of electron and proton radiation on spacecraft which will operate in the trapped radiation belts of the planet Jupiter are described, and the techniques and results of the testing and simulation used in the radiation effects program are ...

Development of a radial diffusion model for Earth’s radiation belts [PDF]

open access: yes, 2007
The radiation belts are the region that energetic charged particles are trapped by Earth’s magnetic field. It is well known that the energetic particles flux are varied during geomagnetic disturbances.

Global threats, local opportunities: ice‐related landforms provide refugia for high‐elevation plants and arthropods

open access: yesEcography, EarlyView.
Ice‐related landforms in mountain areas have been hypothesized to play a key role in the survival of cold‐adapted species threatened by climate change. However, our understanding of such landforms acting as refugia remains speculative. Here we analyse occurrence data, collected through a standardized sampling at 471 sampling points across the European ...

Collisionless phase mixing mimics diffusive transport in radiation belt observations

open access: yesPhysical Review Research
Since the dawn of the space age, observations of energetic particles in planetary radiation belts have been interpreted within a diffusive transport framework, even though the dominant processes that populate and deplete these belts—such as injections ...

Modeling the Dynamic Variability of Sub‐Relativistic Outer Radiation Belt Electron Fluxes Using Machine Learning

open access: yesSpace Weather, 2022
We present a set of neural network models that reproduce the dynamics of electron fluxes in the range of 50 keV ∼1 MeV in the outer radiation belt.

How “Whistling” Plasma Waves Shape Earth’s Radiation Belts [PDF]

open access: yes, 2017
The Van Allen radiation belts surrounding Earth shrink and swell due to plasma waves moving through them, an analysis of satellite data suggests.

Measuring the Earth's Synchrotron Emission from Radiation Belts with a Lunar Near Side Radio Array [PDF]

open access: yes, 2020
International audienceThe high kinetic energy electrons that populate the Earth's radiation belts emit synchrotron emissions because of their interaction with the planetary magnetic field.
