Heating of the Sunlit Polar Cap Ionosphere by Reflected Photoelectrons
Using a 1-D ionosphere-polar wind model and measurements from the Resolute Bay Incoherent Scatter Radar (RISR-N), this paper shows that these reflected photoelectrons are a significant source of heat for…

Solar Cycle Variation of Plasma Mass Density in the Outer Magnetosphere: Magnetoseismic Analysis of Toroidal Standing Alfven Waves Detected by Geotail
We study the variation of plasma mass density in the outer magnetosphere over a solar cycle using mass density estimated from the frequency of fundamental toroidal standing Alfvén waves observed…

First Estimates of Global Free-Tropospheric NO2 Abundances Derived Using a Cloud-Slicing Technique Applied to Satellite Observations from the Aura Ozone Monitoring Instrument (OMI)
We derive free-tropospheric NO2 volume mixing ratios (VMRs) by applying a cloud-slicing technique to data from the Ozone Monitoring Instrument (OMI) on the Aura satellite.

Diagnostics of an Artificial Relativistic Electron Beam Interacting with the Atmosphere
We use a Monte Carlo model to simulate the interaction of a beam of relativistic electrons with the upper atmosphere as they are injected downward from a notional high-altitude injection…

On the Generation/Decay of the Storm-Enhanced Density Plumes: Role of the Convection Flow and Field-Aligned Ion Flow
We present observations of SED plumes during six storms between 2010 and 2013 and comprehensively analyze the associated ionospheric parameters within the plumes.

Imaging Activity in Integrated Circuits
In this paper, we introduce a method for localizing activity in integrated circuits (IC) using a laser scanning microscope.

Role of Conjugate and Local Terminators for Ionospheric Dynamics at Arecibo
Using some recent Plasma drift data at Arecibo, we present evidences of Electric Field (E) changes induced by sunrise and sunset transitions at both local and conjugate regions.

Polymer-Based Flexible Visuo-Haptic Display
We report a flexible visuo-haptic display that allows for interactive haptic feedback on the visual display. The visuo-haptic display is fabricated by integrating a dielectric elastomer (DE) based thin film…

Coordinated Ionospheric Observations Indicating Coupling between Preonset Flow Bursts and Waves That Lead to Substorm Onset
A critical, long-standing problem in substorm research is identification of the sequence of events leading to substorm expansion phase onset.

Design, Development, Implementation, and on-Orbit Performance of the Dynamic Ionosphere Cubesat Experiment Mission
The Dynamic Ionosphere CubeSat Experiment (DICE) mission consists of two 1.5U CubeSats which were launched into an eccentric low Earth orbit on October 28, 2011.

The Effect of Solar Flares, Coronal Mass Ejections, and Solar Wind Streams on Venus’ 5577 Angstrom Oxygen Green Line
We find the greatest emission occurs after CMEs and suggest that particle precipitation is the main contributor to green line emission.

3D Imaging Reveals Electrodynamics of Polar Cap Aurora
Rishbeth prizewinners Hanna Dahlgren and colleagues investigate the nature of an auroral arc appearing within the deep polar cap region.
