PFISR and ROPA Observations of Pulsating Aurora
In the process of modeling the volume emission rates, the PFISR data are inverted to calculate the associated electron energy distribution for comparison with in situ electron measurements from ROPA…

100 W Operation of a Cold Cathode TWT
This paper reports on the experimental studies of implementation of such field emitter arrays as the electron source for a moderate power traveling wave tube (TWT) operating in the C-band…

Coordinated Optical and Radar Image Measurements of Noctilucent Clouds and Polar Mesospheric Summer Echoes
Novel coincident 3-D radar, lidar and optical image measurements of dynamical structures in polar mesosphere summer echoes (PMSE) and noctilucent clouds (NLC) are presented.

Pfisr Observations of Strong Azimuthal Flow Bursts in the Ionosphere and Their Relation to Nightside Aurora
We present two flow burst events observed by the new Poker Flat Advanced Modular Incoherent Scatter Radar (PFISR) in the pre-midnight auroral zone on 28 April 2007, one towards the…

Poker Flat Radar Observations of the Magnetosphere-Ionosphere Coupling Electrodynamics of the Earthward Penetrating Plasma Sheet Following Convection Enhancements
We have used PFISR observations associated with two relatively abrupt southward turnings of the IMF to provide an initial evaluation of aspects of this response.

Observations of D-Region Structure and Atmospheric Tides with PFISR During Active Aurora
We report on combined spectral measurements of the D-region ionosphere and the polar summer mesosphere and lower thermosphere performed on 9 June 2007 with the 450 MHz Poker Flat Incoherent…

Assessing Auroral Electric Field Variance with Coherent and Incoherent Scatter Radar
Line-of-sight F region plasma drifts measured with the Poker Flat Incoherent Scatter Radar (PFISR) during the NASA JOULE II experiment period are compared with estimates derived from E region coherent scatter spectra observed with a 30 MHz imaging radar on common…

Volumetric Imaging of the Auroral Ionosphere: Initial Results from PFISR
This paper demonstrates the capabilities of PFISR for producing three-dimensional volumetric images of E-region ionization patterns produced by the aurora.

Communication Pattern Anomaly Detection in Process Control Systems
To protect these process control systems, we present a learning-based approach for detecting anomalous network traffic patterns.

Mood, Side-Effects and Smoking Outcomes Among Persons with and Without Probable Lifetime Depression Taking Varenicline
Compare mood, prevalence and intensity of treatment side-effects, and abstinence among people with a probable history of major depression (DH+) or not (DH−) who took varenicline and received behavioral smoking…
