The assembly of local communities from regional species pools is shaped by historical aspects of distribution, environmental conditions, and biotic interactions. We studied local community assembly patterns in African annual killifishes of the genus Nothobranchius (Cyprinodontiformes), investigating data from 168 communities across the entire range of regionally co-existing species. Nothobranch...

Team Oshkosh, composed of Oshkosh Corporation, Teledyne Scientific and Imaging Company, VisLab of the University of Parma, Ibeo Automotive Sensor GmbH, and Auburn University, participated in the DARPA Urban Challenge and was one of the 11 teams selected to compete in the final event. Through development, testing, and participation in the official events, we experimented and demonstrated autonom...

This paper describes a system for detecting and estimating the properties of multiple travel lanes in an urban road network from calibrated video imagery and laser range data acquired by a moving vehicle. The system operates in real-time in several stages on multiple processors, fusing detected road markings, obstacles, and curbs into a stable non-parametric estimate of nearby travel lanes. The...

We present the motion planning framework for an autonomous vehicle navigating through urban environments. Such environments present a number of motion planning challenges, including ultrareliability, high-speed operation, complex intervehicle interaction, parking in large unstructured lots, and constrained maneuvers. Our approach combines a model-predictive trajectory generation algorithm for c...

Latest experimental progress is reviewed on the searches for physics beyond the Standard Model using the radiative and electroweak penguin decays of B mesons. This review covers inclusive and exclusive measurements of the b → sγ, b → dγ and b → sll processes, including the first observation of B → Kll and the first attempt to measure the inclusive B → Xsl l branching fraction.

We report here on a series of adaptive optics observations of T Tauri made from Dec. 1993 to Nov. 1997. Observations show an arc-like structure extending toward north and north-west. On the south side a bright tail-like structure extends radially in the south-west direction. Both structures seem to be produced by dust scattering. Close to T Tauri, the south structure forms bright clumps near a ...

The impressive results of the 2007 DARPA Urban Challenge showed that fully autonomous vehicles are technologically feasible with current intelligent vehicle hardware. It is natural to ask how current transportation infrastructure can be improved when most vehicles are driven autonomously in the future. Dresner and Stone proposed a new intersection control mechanism called Autonomous Intersectio...
