Speaker Recognition Using Syllable-Based Constraints for Cepstral Frame Selection
We describe a new GMM-UBM speaker recognition system that uses standard cepstral features, but selects different frames of speech for different subsystems.

Comparison of AMIE-Modeled and Sondrestrom-Measured Joule Heating: a Study in Model Resolution and Electric Field-Conductivity Correlation
We investigate by comparing the Joule heating measured by the Sondrestrom incoherent scatter radar during a storm with that modeled by the Assimilative Mapping of Ionospheric Electrodynamics (AMIE) procedure.

Simultaneous Quantification of Perfusion and Permeability in the Prostate Using Dynamic Contrast-Enhanced Magnetic Resonance Imaging with an Inversion-Prepared Dual-Contrast Sequence
The aim of the present study was to quantify both perfusion and extravasation in the prostate to discriminate tumor from healthy tissue, which might be achieved by dynamic contrast-enhanced magnetic…

Venus Ground-Based Observations: a Proposal
We have executed an efficient procedure for time-sharing to achieve a rapid Venus observation on Keck I/HIRES.

Development of a Transillumination Infrared Modality for Differential Vasoactive Optical Imaging
We present the development and implementation of a new near infrared transillumination imaging modality for tissue imaging. Exogenous inhaled hyperoxic and hypercarbic gases are used as "vasoactive contrast agents" via…

A Safety-Case Approach for Certifying Adaptive Systems
In this paper, we argue that analysis tools based on recent advances in formal methods (SMT solvers, infinite bounded model checkers, and k-induction) can provide suitable modeling notations, effective analysis,…

Target Tracking with Incomplete Detection
In this paper, we address the multiple target tracking problem as a maximum a posteriori problem.

Data-Driven Lexicon Expansion for Mandarin Broadcast News and Conversation Speech Recognition
We present a data-driven framework for expanding the lexicon to improve Mandarin broadcast news and conversation speech recognition.
-
Improving Robustness of MLLR Adaptation with Speaker-Clustered Regression Class Trees
We introduce a strategy for modeling speaker variability in speaker adaptation based on maximum likelihood linear regression (MLLR).

Scaleable Manufacture of HIV-1 Entry Inhibitor Griffithsin and Validation of Its Safety and Efficacy as a Topical Microbicide Component
We report a manufacturing breakthrough for griffithsin (GRFT), one of the most potent HIV entry inhibitors. Plant-produced GRFT (GRFT-P) was shown as active against HIV at picomolar concentrations, directly virucidal…

Mesomechanical Constitutive Relations for Glass and Ceramic Armor
We describe a model that uses microfailure and fragment flow constitutive data, show how the model links to continuum models, and compare computational results with glass penetration tests.

Using Evidence Centered Design For Learning (ECDL) To Examine the ASSISTments system
We introduce a design methodology – Evidence Centered Design for Learning (ECDL) that supports the design of educational systems in terms of evidentiary arguments.
