Comparison of the Antinociceptive and Antirewarding Profiles of Novel Bifunctional Nociceptin Receptor/Mu-Opioid Receptor Ligands: Implications for Therapeutic Applications
We hypothesized that NOPr agonists, with bifunctional activity at the μ-opioid receptor (MOPr), may function as nonaddicting analgesics or as drug abuse medications.

An anticorrelation kernel for subsystem training in multiple classifier systems
We present a method for training support vector machine (SVM)-based classification systems for combination with other classification systems designed for the same task.

Development of the 2008 SRI Mandarin Speech-To-Text System for Broadcast News and Conversation
We describe the recent progress in SRI’s Mandarin speech-to-text system developed for 2008 evaluation in the DARPA GALE program. A data-driven lexicon expansion technique and language model adaptation methods contribute to the improvement in recognition performance.

Modeling other talkers for improved dialog act recognition in meetings
We propose a new approach that takes into account speech from other talkers, relying only on speech/non-speech information from all participants.

Some Economic Consequences of Improving Mathematics Performance
In this report, we examine how improving mathematics performance has economic consequences through raising high school graduation rates.

Classification-Based Strategies for Combining Multiple 5-W Question Answering Systems
We describe and analyze inference strategies for combining outputs from multiple question answering systems each of which was developed independently.

First Observations of Large-Scale Wave Structure and Equatorial Spread F Using Certo Radio Beaconon the C/NOFS Satellite
First observations of large-scale wave structure and the subsequent development of equatorial spread F, using total electron content derived from the ground based reception of beacon signals from the CERTO radio beacon on board C/NOFS satellite, are presented.
