Structure and sources of disorder in poly(3-hexylthiophene) crystals investigated by density-functional calculations with van der Waals interactions
The crystal structure of poly(3-hexylthiophene) (P3HT) has been studied by first-principles calculations based on density functional theory.

Automatic identification of speaker role and agreement/disagreement in broadcast conversation
We present supervised approaches for detecting speaker roles and agreement/disagreement between speakers in broadcast conversation shows in three languages: English, Arabic, and Mandarin.

Comparison of 32 x 128 and 32 x 32 Geiger-Mode APD FPAs for Single Photon 3D LADAR Imaging
We present results obtained from 3D imaging focal plane arrays (FPAs) employing planar-geometry InGaAsP/InP Geiger-mode avalanche photodiodes (GmAPDs) with high-efficiency single photon sensitivity at 1.06 μm.

Quantifying the Breakdown of the Born-Oppenheimer Approximation in Surface Chemistry
In this paper we show that molecular-beam surface scattering experiments can be used to derive quantitative information about the magnitude of BOA breakdown.

Recent progress in prosodic speaker verification
In this paper, we show that performance can be significantly improved with the use of probabilistic linear discriminant analysis (PLDA) for session variability compensation.
