Microarray Evaluation of the Listeria Monocytogenes Infection and Amoxicillin Treatment in Mice
By using Affymetrix Mouse Genome Arrays and biological replicates, the predictive value of liver and blood gene expression profiles previously identified was validated as predictive of Listeria monocytogenes infection severity.

Object Tracking and Classification in Aerial Videos
We combine the layer segmentation approach with background stabilization and post-tracking refinement to reliably detect small moving objects at the relatively low processing speed.

VideoQuest: Managing Large-Scale Aerial Video Database Through Automated Content Extraction
In this paper, we introduce an aerial video management and exploitation system named VideoQuest that manages large-scale aerial video database through automated video processing and content extraction.

Laser-Ionization Mass Spectrometry of Explosives and Chemical Warfare Simulants
The objective of the present study was to better understand the photophysics of explosives and chemical warfare simulants in order to develop better performing analytical tools.

Airlift Mission Monitoring and Dynamic Rescheduling
We describe the Flight Manager Assistant, a prototype system, designed to support real-time management of airlift operations at the USAF Air Mobility Command.

Observations of Plasma Line Splitting in the Ionospheric Incoherent Scatter Spectrum
Wide-bandwidth ionospheric incoherent scatter (IS) spectra obtained using the Arecibo IS radar show the occurrence of a split in the plasma line (i.e., two plasma lines) when the plasma frequency…

On-The-Move Independently Moving Target Detection
This paper describes a system for automatically detecting potential targets (that pop-up or move into view) and to cue the operator to potential threats. We present a 3D approach for…

Precise Visual Navigation Using Multi-Stereo Vision and Landmark Matching
In this paper, we propose a set of techniques which greatly reduce the long term drift and also improve its robustness to many failure conditions.

Segmentation of Aerial Surveillance Video Using a Mixture of Experts
We propose a video segmentation algorithm for aerial surveillance video. The algorithm uses a Mixture of Experts consisting of a supervised image segmentation algorithm named the Trainable Sequential MAP segmentation…

Towards a Practical Stereo Vision Sensor
This paper describes an experimental framework for determining these limits using image processing algorithms, operating on graphically synthesized imagery, with performance envelope validation on real stereo image data.

Vehicle Fingerprinting for Reacquisition and Tracking in Videos
We address the problem of vehicle matching when multiple observations of a vehicle are separated in time such that frames of observations are not contiguous, thus prohibiting the use of…

The complete genome sequence of Francisella tularensis, the causative agent of tularemia
We report the complete genome sequence of a highly virulent isolate of F. tularensis. The sequence uncovers previously uncharacterized genes encoding type IV pili, a surface polysaccharide and iron-acquisition systems.
