Comparative Earth and Jupiter's radiation belts [PDF]
, 2020 International audienceSince the 1990s ONERA has developed physical models of the Earth radiation belts, called the Salammbô models. During the early 2000s, these models have been adapted to Jupiter case, and then to Saturn since 2009.

Statistical evaluation of nylon chemical recycling through acidolysis
Polymer International, EarlyView.Sustainable PA6 recycling through acidolysis enabled temperature‐driven depolymerization, modeled by regression analysis. Recycled products successfully replaced up to 30% monomer while preserving PA6 chemical composition or crystalline structure. Abstract This study focuses on the sustainability of plastics reporting the recycling of polyamide (PA ...

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

Chorus wave power at the strong diffusion limit overcomes electron losses due to strong diffusion
Nature CommunicationsEarth’s radiation belts consist of high-energy charged particles trapped by Earth’s magnetic field. Strong pitch angle diffusion of electrons caused by wave-particle interaction in Earth’s radiation belts has primarily been considered as a loss process ...

Radiation Belts and Plasmapause Fluctuate Under Solar Storm [PDF]
, 2004 In this visualization, we see the interaction of the radiation belts (violet-white), the plasmapause (green surface) and magnetopause (grey surface).

Quarterly Journal of the Royal Meteorological Society, EarlyView.We investigate whether Central European heatwaves (HWs) forming under omega blocking differ from those enabled by subtropical ridges, in terms of both air‐mass origin and processes warming air parcels along their way. Using ERA5‐based backward trajectories and a Lagrangian temperature anomaly decomposition, we identify significant differences in the ...

University of California Radiation Laboratory Report UCRL-5993 [PDF]
, 1960 . Three groups of 100 foot holes were drilled vertically downward from the floor of U 12e main tunnel and U 123.03 drift at the Nevada Test Site. Distances between holes in each group varied from 13 to 375 feet.

Forecast‐Error Diagnostics in Neural Weather Models
Quarterly Journal of the Royal Meteorological Society, EarlyView.Deep learning weather prediction models enable efficient forecast‐error diagnostics through auto‐differentiation and low computational cost. We apply grid‐point relaxation and gradient‐based error sensitivity to identify key forecast‐error sources. Results show that medium‐range forecasts in the midlatitudes benefit most from relaxing the stratosphere ...

Dynamics and thermodynamics of the fast and slow Madden–Julian Oscillation
Quarterly Journal of the Royal Meteorological Society, EarlyView.The results of this study highlight the MJO as a complex phenomenon, the behavior of which is driven by an interplay of thermodynamic and dynamic processes. The MJO's distinct speeds are controlled by different mechanisms: slow MJOs propagate eastward primarily via horizontal moisture advection, fast MJOs by vertical moisture advection.

Cyclotron acceleration of radiation belt electrons by whistlers [PDF]
, 2003 The work considers the non linear scattering of energetic electrons in the earth's radiation belts due to cyclotron interaction with VLF whistlers.
