The Heliosphere and Local Interstellar Medium from Neutral Atom Observations at Energies Below 10 keV. [PDF]

, 2022
As the heliosphere moves through the surrounding interstellar medium, a fraction of the interstellar neutral helium, hydrogen, and heavier species crossing the heliopause make it to the inner heliosphere as neutral atoms with energies ranging from few eV

Remote energetic neutral atom imaging of electric potential over a lunar magnetic anomaly [PDF]

, 2013
The formation of electric potential over lunar magnetized regions is essential for understanding fundamental lunar science, for understanding the lunar environment, and for planning human exploration on the Moon.

PICKUP IONS FROM ENERGETIC NEUTRAL ATOMS

The Astrophysical Journal, 2010
The inner source of pickup ions (PUIs) was once thought to derive exclusively from the interaction between solar wind and interplanetary grains near the Sun. Recently, however, Gruntman & Izmodenov suggested that inner source hydrogen may derive from energetic neutral atoms (ENAs) from the outer heliosphere.

Science Opportunities for IMAP-Lo Observations of Interstellar Neutral Helium, Neon, and Oxygen during a Maximum of Solar Activity

The Astrophysical Journal Supplement Series, 2023
Direct-sampling observations of interstellar neutral (ISN) species and their secondary populations give information about the physical state of the local interstellar medium and processes occurring in the outer heliosheath.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

An Anomalous Cosmic-Ray Mediated Termination Shock: Implications for Energetic Neutral Atoms

The Astrophysical Journal Letters, 2023
The Voyager 2 crossing of the termination shock indicated that most of the upstream energy from the thermal solar wind ions was transferred to pickup ions (PUIs) and other energetic particles downstream of the shock.

Charge-Exchange Byproduct Cold Protons in the Earth’s Magnetosphere

Frontiers in Astronomy and Space Sciences, 2022
Owing to the spatial overlap of the ion plasma sheet (ring current) with the Earth’s neutral-hydrogen geocorona, there is a significant rate of occurrence of charge-exchange collisions in the dipolar portion of the Earth’s magnetosphere.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Energetic neutral atoms in cometary comae

The Astrophysical Journal, 1990
A Monte Carlo simulation model is constructed to follow the collisional scattering of the energetic neutral atoms (ENAs) in the cometary coma. It is found that collisional thermalization in the inner coma could lead to the production of an isotropic flux of fast-moving atoms with velocities on the order of 40-60 km/s.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
