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.

Seasonal and Diurnal Variability of the Meteor Flux at High Latitudes Observed Using PFISR
Latitudinal and seasonal variability of the micrometeor input function: A study using model predictions and observations from Arecibo and PFISR.

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…

Remote Oxygen Sensing By Ionospheric Excitation (ROSIE)
We can demonstrate an approach to remotely detect O-atoms at the altitudes relevant to IM experiments, which we call remote oxygen sensing by ionospheric excitation (ROSIE).

Evaluation of Teleoperated Surgical Robots in an Enclosed Undersea Environment
Over three NASA Extreme Environment Mission Operations (NEEMO) missions, researchers evaluated different surgical robotic systems, AESOP, the SRI M7, and the University of Washington BioRobotic Laboratory’s RAVEN.

Mixed-Initiative Negotiation: Facilitating Useful Interaction Between Agent/Owner Pairs
A mixed-initiative agent for personal time management interacts not only with its human owner but also with other agents and humans that share or depend on the same time commitments.
