Effect of Various Coal Gas Contaminants on the Performance of Solid Oxide Fuel Cells: Part III. Synergistic Effects
The present work presents the results of a study of the synergistic effects of four contaminants of major concern—S, As, P, and Cl, at the ppm level and in combinations of two, three, or four kinds—on the performance of Ni-YSZ/YSZ/LSM solid oxide fuel cells.

Leveraging Evidence-Centered Design In Large-Scale Test Development (Large-Scale Assessment Technical Report 4)
This brief on Early Warning Systems is the first in a series of briefs being released this fall with key findings about these high school improvement strategies.

On the use of speaker superfactors for speaker recognition
We propose a new JFA scoring method that is both symmetrical and efficient.

Orally Bioavailable Anti-HBV Dinucleotide Acyloxyalkyl Prodrugs
The acyloxyalkyl derivatives of a model anti-HBV dinucleotide were synthesized and evaluated as orally bioavailable prodrugs. Our studies have led to the identification of the first orally bioavailable dinucleotide prodrugs for further therapeutic development against the hepatitis B virus (HBV).

Quantitative Fiber Tracking of Lateral and Interhemispheric White Matter Systems in Normal Aging: Relations to Timed Performance
Using our quantitative fiber tracking approach, we assessed fiber tract integrity of samples of major white matter cortical, subcortical, interhemispheric, and cerebellar systems (11 bilateral and 2 callosal) on DTI data collected at 1.5 T magnet strength.

Scaffolding knowledge communities in the classroom: New opportunities in the Web 2.0 era
This chapter reports two studies that used a wiki to deliver a new curriculum model that blends scripted inquiry activities with collaborative knowledge construction in secondary school biology.

Discounted Deterministic Markov Decision Processes and Discounted All-Pairs Shortest Paths
We present algorithms for finding optimal strategies for discounted, infinite-horizon, Determinsitc Markov Decision Processes (DMDPs).

A Partially Linear Tree-Based Regression Model for Multivariate Outcomes
We propose a multilocus association test for the study of multivariate traits. The test is derived from a partially linear tree-based regression model for multiple outcomes.

Increase in Tissue Inhibitor of Metalloproteinase-2 (TIMP-2) Levels and Inhibition of MMP-2 Activity in a Metastatic Breast Cancer Cell Line by an Anti-Invasive Small Molecule SR13179
We report that a novel small molecule synthetic flavanoid SR13179, which inhibits the invasion of a highly metastatic human breast cancer cell line MCF-10CA1a through Matrigel, significantly increases protein and mRNA levels of TIMP-2 in a time- and dose-dependent manner.

Nicotinic Receptor-Mediated Reduction in L-DOPA-Induced Dyskinesias May Occur Via Desensitization
The present experiments were performed to understand the mechanisms whereby nicotine reduces l-DOPA-induced AIMs. We used a well established model of dyskinesias, l-DOPA-treated unilateral 6-hydroxydopamine-lesioned rats.

Comparing the contributions of context and prosody in text-independent dialog act recognition
We propose a framework for employing both speech/non-speech-based (“contextual”) features and prosodic features, and apply it to DA segmentation and classification in multiparty meetings.

Dynamics of North American Sector Ionospheric and Thermospheric Response During the November 2004 Superstorm
We present a study of ionospheric and thermospheric response during a November 9–10, 2004 major geomagnetic storm event (DsT ∼−300 nT).
