Martian atmosphere sputtering escape generated by penetrating hydrogen energetic neutral atoms
Earth and Planetary PhysicsAtmospheric escape plays a critical role in shaping the long-term climate evolution of Mars. Among the various escape mechanisms, energetic neutral atoms (ENAs) generated through charge exchange between solar wind ions and exospheric neutrals serve as an

IMAGE/high‐energy energetic neutral atom: Global energetic neutral atom imaging of the plasma sheet and ring current during substorms [PDF]
Journal of Geophysical Research: Space Physics, 2002 Energetic neutral atom (ENA) images in the 10–60 keV range show the substorm dynamics of the ion distribution out to 14 RE in the plasma sheet. The images were obtained during two substorms in the mainphase of the 4 October 2000 storm by the high‐energy energetic neutral atom (HENA) imager on board the IMAGE satellite. During the two substorm sequences

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations
Advanced Biology, Volume 9, Issue 3, March 2025.Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Polar CEPPAD/IPS energetic neutral atom (ENA) images of a substorm injection [PDF]
, 2000 The CEPPAD Imaging Proton Spectrometer on the POLAR spacecraft has proven to perform very well as an Energetic Neutral (ENA) atom imager, despite the fact that it was designed primarily for measuring energetic ions in-situ.

Inversion of Upstream Solar Wind Parameters from ENA Observations at Mars
Remote Sensing, 2023 An algorithm has been developed to invert the solar wind parameters from the hydrogen energetic neutral atom (H-ENA) measured in near-Mars space. Supposing the H-ENA is produced by change exchange collision between protons that originated in the solar ...

Advanced Engineering Materials, EarlyView.New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Origins of Persistence in Energetic Neutral Atom Time Series from IBEX
The Astrophysical JournalRecently, we studied the persistence of energetic neutral atom (ENA) fluxes recorded by the Interstellar Boundary Explorer (IBEX) from the north and south polar regions by examining the correct time order for the 14 yr of IBEX data.
