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.

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…

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.

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.

Signpost from the masses: learning effects in an exploratory social tag search browser
In this paper, we present the design of a tag-based exploratory system and detail an experiment in understanding its effectiveness.

Remembrance of things tagged: How tagging effort affects tag production and human memory
We developed a low-effort interaction method called Click2Tag for social bookmarking. Information foraging theory predicts that the production of tags in will increase as the effort required to do so…

Annotate once, appear anywhere: collective foraging for snippets of interest using paragraph fingerprinting
In this paper we report how we explore the idea of paragraph fingerprinting to achieve the goal of annotate once, appear anywhere in a social annotation system called SparTag.us.
