Prediction of Energetic Electrons in the Inner Radiation Belt and Slot Region With a Double‐Layer LSTM Neural Network Model

Space Weather
The prediction of high‐energy radiation belt electrons is vital for preventing their damage to satellites. Previous machine learning models mostly predict the fluxes of high‐energy electrons (hundreds of keV to MeV) in the outer radiation belt and slot ...

Lightning-induced neutrons as a possible source of charged particles in the Earth’s inner radiation belt

Earth and Planetary Physics
The Van Allen radiation belts are doughnut-shaped zones surrounding Earth, filled with highly energetic charged particles whose sources or loss mechanisms have been investigated for decades. As for the inner belt, cosmic ray albedo neutron decay (CRAND),

Multi-satellite simultaneous observations of magnetopause and atmospheric losses of radiation belt electrons during an intense solar wind dynamic pressure pulse [PDF]

Annales Geophysicae, 2016
Radiation belt electron flux dropouts are a kind of drastic variation in the Earth's magnetosphere, understanding of which is of both scientific and societal importance. Using electron flux data from a group of 14 satellites, we report multi-satellite

Radiation belt probes launched [PDF]

Eos, Transactions American Geophysical Union, 2012
Storms on Earth delayed by only a few days the launch of NASA's Radiation Belt Storm Probes (RBSP), which blasted off on 30 August for a 2‐year tour to explore the Van Allen radiation belts. The two satellites will help scientists learn about the processes that affect electrons and ions in the donut‐shaped belts and how the belts change in the context ...

Jupiter's Radiation Belts and Upper Atmosphere [PDF]

Symposium - International Astronomical Union, 1974
Models of Jupiter's radiation belts have been constructed to determine the distribution of particles and their energies which will produce the observed decimetric radio emission. Data on the spectrum and the variation of emission with Jovian longitude have been used to show that the relativistic particles have a nearly isotropic distribution with high ...

Using ACIS on the Chandra X-ray Observatory as a particle radiation monitor

, 2010
The Advanced CCD Imaging Spectrometer (ACIS) is one of two focal-plane instruments on the Chandra X-ray Observatory. During initial radiation-belt passes, the exposed ACIS suffered significant radiation damage from trapped soft protons scattering off the

An optimizing microseismic method for rock burst early warning based on mining production process

Deep Underground Science and Engineering, EarlyView.
A classification early warning method of rock burst based on hourly microseismic data is proposed, which can be combined with the on‐site production process to provide more timely warning. Abstract Microseismic (MS) events have been reported in nearly every coal mining country, which could well lead to rock burst in underground coal mines.

What effect do substorms have on the content of the radiation belts? [PDF]

, 2016
Substorms are fundamental and dynamic processes in the magnetosphere, converting captured solar wind magnetic energy into plasma energy. These substorms have been suggested to be a key driver of energetic electron enhancements in the outer radiation ...

Facet‐Tailored Co3O4 as Electronic Regulator and Stabilizing Support for Ru Nanocluster: Toward Efficient Alkaline HER

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Facet‐engineered Ru@Co3O4 nanosheets precisely anchor Ru nanoclusters on the Co3O4 (111) facets, optimizing the hydrogen‐bond network of interfacial water and downshifting the Ru d‐band center. The Ru@Co3O4 NSs show outstanding HER activity and long‐term durability in AEMWE devices. This work demonstrates a crystal facet engineering strategy to develop
