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.

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.

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.

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.

Across-phone variability and diagonal term in joint factor analysis for speaker recognition
We investigate usefulness of across-phone variability for speaker recognition in a joint factor analysis (JFA) framework. We estimate the variability as across-phone covariance within a conversation side averaged over all conversations.

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.

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.

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).

Fast likelihood computation using hierarchical Gaussian shortlists
We investigate the use of hierarchical Gaussian shortlists to speed up Gaussian likelihood computation.

Indirect Validation of Tropospheric Nitrogen Dioxide Retrieved from the OMI Satellite Instrument: Insight Into the Seasonal Variation of Nitrogen Oxides at Northern Midlatitudes
We examine the seasonal variation in lower tropospheric nitrogen oxides at northern midlatitudes by evaluating tropospheric NO2 columns observed from the Ozone Monitoring Instrument.

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.

LC/MS Characterization of Impurities and Degradation Products of a Potent Antitumor Peptidic Dimer, CU201
An HPLC method was developed, as part of a study supported by the National Cancer Institute’s (NCI’s) Rapid Access to Interventional Development (RAID) program, to assess the purity and stability of CU201.
