Ring current dynamics in the Earth's inner magnetosphere
地球与行星物理论评, 2022 The terrestrial ring current, flowing near the equator at the altitude of 2 RE～7 RE, is one of the most significant electric current systems of the Earth's magnetosphere.

Van Allen Probes Observations of Oxygen Ions at the Geospace Plume
Frontiers in Astronomy and Space Sciences, 2021 The geospace plume couples the ionosphere, plasmasphere, and magnetosphere from sub-auroral regions to the magnetopause, on polar field lines, and into the magnetotail.

Oxygen sensing by ion channels [PDF]
Kidney International, 1997 Oxygen is required for the survival of all higher life forms due to its role in mitochondrial respiration permitting ATP synthesis by oxidative phosphorylation. Oxygen is also necessary for many other cellular functions, including the synthesis of steroid hormones or the generation of reactive oxygen species in the macrophage defense response.

Radioactive Beams for Image-Guided Particle Therapy: The BARB Experiment at GSI
Frontiers in Oncology, 2021 Several techniques are under development for image-guidance in particle therapy. Positron (β+) emission tomography (PET) is in use since many years, because accelerated ions generate positron-emitting isotopes by nuclear fragmentation in the human body ...

Large-scale inverted-V channels of upflowing oxygen ions pumped by Alfvén waves
Earth and Planetary Physics, 2023 Large-scale inverted-V channels of upflowing oxygen ions are frequently identified in data collected by Cluster, at all local times, near the open-closed field line boundary over Earth’s high-latitude ionosphere-occur with downward propagating MHD Alfvén

Oxygen‐dependent ion transport in erythrocytes [PDF]
Acta Physiologica, 2009 AbstractThe present contribution reviews current knowledge of apparently oxygen‐dependent ion transport in erythrocytes and presents modern hypotheses on their regulatory mechanisms and physiological roles. In addition to molecular oxygen as such, reactive oxygen species, nitric oxide, carbon monoxide, regional variations of cellular ATP and hydrogen ...

K‐Shell Photoabsorption of Oxygen Ions [PDF]
The Astrophysical Journal Supplement Series, 2005 Extensive calculations of the atomic data required for the spectral modelling of the K-shell photoabsorption of oxygen ions have been carried out in a multi-code approach. The present level energies and wavelengths for the highly ionized species (electron occupancies 2 <= N <= 4) are accurate to within 0.5 eV and 0.02 A, respectively.
