Non-Maxwellian Proton Velocity Distributions in Nonradiative Shocks

open access: yes, 2008
The Balmer line profiles of nonradiative supernova remnant shocks provide the means to measure the post-shock proton velocity distribution. While most analyses assume a Maxwellian velocity distribution, this is unlikely to be correct.

A Sensitivity Study of the Enceladus Torus [PDF]

open access: yes, 2009
We have developed a homogeneous model of physical chemistry to investigate the neutral-dominated, water-based Enceladus torus. Electrons are treated as the summation of two isotropic Maxwellian distributions$-$a thermal component and a hot component. The

Dependence of Lunar Pickup Ion Flux on Source Location: ARTEMIS Observations

open access: yesThe Astrophysical Journal
The Moon is enveloped in an exosphere, which is comprised of a variety of neutral atoms and molecules. Once exospheric neutrals are ionized by photons, protons, or electrons from the Sun, the resulting ions are accelerated by the electromagnetic fields ...

Ion cyclotron waves, pickup ions, and Io's neutral exosphere [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2000
During Galileo's December 1995 encounter with Io, the magnetometer observed very strong electromagnetic waves near the SO2+ gyrofrequency. The amplitude of these waves previously has been used to determine the density of SO2+, as well as the production rate near Io.

Autonomous Machine Learning‐Based Classification and Arrangement of Submillimeter Objects Using a Capillary Force Gripper

open access: yesAdvanced Intelligent Discovery, EarlyView.
This study presents an automated system integrating a capillary force gripper and machine learning‐based object detection for sorting and placing submillimeter objects. The system achieved stable and simultaneous manipulation of four object types, with an average task time of 86.0 seconds and a positioning error of 157 ± 84 µm, highlighting its ...

Low‐Cost and Detunable Wireless Resonator Glasses for Enhanced Eye MRI With Concurrent High‐Quality Whole‐Brain MRI

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 499-507, July 2026.
ABSTRACT Purpose To develop a wearable wireless resonator glasses design that enhances eye MRI signal‐to‐noise ratio (SNR) without compromising whole‐brain image quality at 7 T. Methods The device integrates two detunable LC loop resonators into a lightweight, 3D‐printed frame positioned near the eyes.
