Decameter Structure in Heater-Induced Airglow at the High Frequency Active Auroral Research Program Facility
On 28 October 2008, small-scale rayed artificial airglow was observed at the High frequency Active Auroral Research Program (HAARP) heating facility by the HAARP telescopic imager.

Design and Performance of Single Photon APD Focal Plane Arrays for 3-D LADAR Imaging
We describe the design, fabrication, and performance of focal plane arrays (FPAs) for use in 3-D LADAR imaging applications requiring single photon sensitivity.

Scaffolding Group Explanation and Feedback with Handheld Technology: Impact on Students’ Mathematics Learning
We compared group and individual feedback, using two technologies: Technology-mediated, Peer-Assisted Learning (TechPALS), and a popular desktop product, which provides feedback to individual students as they solve fractions problems individually.

Composite Imaging of Auroral Forms and Convective Flows During a Substorm Cycle
Measurements obtained with the electronically steerable Poker Flat Incoherent Scatter Radar (PFISR) and collocated all-sky camera were used to construct composite images of ionospheric convective flows and auroral forms.

Lightning-Generated NO(X) Seen By the Ozone Monitoring Instrument During NASA’s Tropical Composition, Cloud and Climate Coupling Experiment (TC(4))
We present case studies identifying lightning-generated upper tropospheric NOx (LNOx) observed during NASA's Tropical Composition, Cloud and Climate Coupling Experiment (TC4) in July and August 2007.

The Importance of Fuel Dissociation and Propargyl + Allyl Association for the Formation of Benzene in a Fuel-Rich 1-Hexene Flame
Fuel decomposition and benzene formation processes in a premixed, laminar, low-pressure, fuel-rich flame of 1-hexene are investigated.

Geiger-Mode Avalanche Photodiode Focal Plane Arrays for Three-Dimensional Imaging LADAR
We report on the development of focal plane arrays (FPAs) employing two-dimensional arrays of InGaAsP-based Geiger-mode avalanche photodiodes (GmAPDs).

Preclinical Pharmacokinetic, Toxicological and Biomarker Evaluation of SR16157, a Novel Dual-Acting Steroid Sulfatase Inhibitor and Selective Estrogen Receptor Modulator
SR16157 is a novel dual-acting inhibitor of estrogen action that irreversibly inhibits the estrogen biosynthetic enzyme steroid sulfatase and releases the selective estrogen receptor modulator SR16137, which blocks the estrogen…

Alpha 6 Beta 2*And Alpha 4 Beta 2*Nicotinic Receptors Both Regulate Dopamine Signaling with Increased Nigrostriatal Damage: Relevance to Parkinson’s Disease
We investigated the effect of varying nigrostriatal damage on α6β2* and α4β2* receptor-modulated dopamine signaling using cyclic voltammetry.

Biological Impact of Low Dose-Rate Simulated Solar Particle Event Radiation in Vivo
C57Bl6-lacZ animals were exposed to a range of low dose-rate simulated solar particle event (sSPE) radiation at the NASA-sponsored Research Laboratory (NSRL) at Brookhaven National Laboratory (BNL).
-
Efficient Variable Elimination for Semi-Structured Simple Temporal Networks with Continuous Domains
We show that for an Simple Temporal Network, messages can be represented compactly as sub-STNs. We then present an efficient message-passing scheme for computing the minimal constraints of an STN.

Nonprofits and the Valley of Death in Drug Discovery
The research and development (R&D) process that ultimately leads to effective drugs is exceedingly difficult, and often the public does not understand the drug discovery pipeline.
