Modeling prior belief for speaker verification SVM systems
In this paper we propose to relax the assumption that the covariance matrix is the identity matrix, allowing it to be a more general block diagonal matrix. We show results…

Translational Studies of Alcoholism: Bridging the Gap
Together, studies in humans and animal models have provided support for the involvement of specific brain structures over the course of alcohol addiction.

Weakly Supervised Training for Parsing Mandarin Broadcast Transcripts
We compare co-training to self-training, and our results show that performance using co-training is significantly better than with self-training and both co-training and self-training with a small seed labeled corpus…

Development of the SRI/Nightingale Arabic ASR System
We describe the large vocabulary automatic speech recognition system developed for Modern Standard Arabic used for the 2007 GALE evaluation as part of the speech translation system.
-
Fast Color/Texture Segmentation for Outdoor Robots
We present results of applying our descriptor for segmenting a synthetic image and compare it against other state-of-the-art descriptors.

Logical Hierarchical Hidden Markov Models for Modeling User Activities
In this work we develop a representation that naturally combines the power of both relational and hierarchical models in the form of Logical Hierarchical Hidden Markov Models (LoHiHMMs).

Acceleration Compensation for Vehicle Based Telesurgery on Earth or in Space
This paper introduces new work focused on compensating for unintended master and slave manipulator motion resulting from accelerations of the environment within which they are operated.

Gene Expression Analysis Reveals New Possible Mechanism of Vancomycin-Induced Nephrotoxicity and Identifies Gene Markers Candidates
The goals of this study were to gain insights into molecular mechanisms of nephrotoxicity at the genomic level, evaluate gene markers of vancomycin-induced kidney injury, and compare gene expression responses…

Measuring Family Outcomes Considerations for Large-Scale Data Collection in Early Intervention
This article discusses issues and considerations in documenting family outcomes in the context of large-scale assessments involving many families and and describes the initial development of a survey instrument that could…

Novel Enhancement of Thin-Form-Factor Galvanic Cells: Probing Halogenated Organic Oxidizers and Metal Anodes
The work reported herein demonstrates a novel method to improve the overall performance of thin-form-factor galvanic cells, fabricated via micro-electromechanical systems (MEMS) processes.

Step Formation on Hydrogen-Etched 6H-Sic{0 0 0 1} Surfaces
The formation of step bunches and/or facets on hydrogen-etched 6H-SiC(0 0 0 1) and (0001¯) surfaces has been studied, using both nominally on-axis and intentionally miscut (i.e. vicinal) substrates.

Thermochemistry of the Gaseous Vanadium Chlorides VCl, VCl2, VCl3, and VCl4
Gaseous equilibria in the V−Ag−Cl system were studied at elevated temperatures by effusion-beam mass spectrometry, where the pertinent species were generated by reaction of Cl2(g) with V + Ag granules…
