Hand-held flow cytometer for point of care CD4 testing
PARC has demonstrated a new optical detection technique termed spatially modulated emission that delivers high signal-to-noise discrimination without precision optics to enable a flow cytometer that can combine high performance,…
-
Microfluidic platform for point-of-need analyte diagnostics based on spatial modulation detection
To help sharpen the focus on alternative approaches, this presentation will describe an optical detection technique that delivers high effective sensitivity (i.e., high S/N) without complex optics or bulky, expensive…

Spectacular Low- and Mid-Latitude Electrical Fields and Neutral Winds During a Superstorm
In November 2004, a major magnetic storm occurred, a lengthy portion of which was recorded by the Upper Atmospheric Radar Chain.

The Economic Impact of Engineering Research Centers: Preliminary Results of a Pilot Study
This article describes the results of a pilot study that tested the feasibility of estimating quantitatively the regional and economic impacts of NSF-supported Engineering Research centers.

An Analysis of Student Practices in Asynchronous Computer Conferencing Courses
The current study examined the online habits and “survival strategies” of 57 students enrolled in graduate-level distance education courses.

IPY Observations of Ionospheric Yearly Variations from High- to Middle-Latitude Incoherent Scatter Radars
The main focus of this paper is on the noon-time baseline annual and semiannual variations, with an emphasis on the less-known height dependency, for those geophysically important areas.

Preparing Students for Future Learning with Teachable Agents
One valuable goal of instructional technologies in K-12 education is to prepare students for future learning. Two classroom studies examined whether Teachable Agents (TA) achieves this goal.

Stimulation of Lateral Hypothalamic Glutamate and Acetylcholine Efflux By Nicotine: Implications for Mechanisms of Nicotine-Induced Activation of Orexin Neurons
Here, we used in vivo microdialysis to determine the effect of acute systemic or local nicotine on glutamate, acetylcholine, and GABA efflux in the LH/PFA of rats.

Automatic disfluency removal for improving spoken language translation
We examine the impact of disfluencies from broadcast conversation data on our hierarchical phrase-based SMT system and implement automatic disfluency removal approaches for cleansing the MT input.

Assessing Systems Thinking and Complexity in Science
This technical report provides support for designing tasks that assess systems thinking, in the form of a design pattern.

On Seeding Equatorial Spread F During Solstices
Seasonal migration and latitudinal alignment of the inter-tropical convergence zone with the magnetic dip equator is suggested as the missing source, and shown able to fill that void.
