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…

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.

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.

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.

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.

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.

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…
