Recent in vivo neuroimaging studies revealed that several brain networks are altered in prenatal cocaine exposure (PCE) affected adolescent brains. However, due to a lack of dense and corresponding cortical landmarks across individuals, the systematical alterations of functional connectivities in large-scale brain networks and the alteration of structural brain architecture in PCE affected brai...

Do humans integrate experience on specific routes into metric survey knowledge of the environment, or do they depend on a simpler strategy of landmark navigation? The authors tested this question using a novel shortcut paradigm during walking in a virtual environment. The authors find that participants could not take successful shortcuts in a desert world but could do so with dispersed landmark...

Landmarks play crucial roles in human geographic knowledge. There has been much work focusing on the extraction of landmarks from geographic information systems (GIS) or 3D city models. The extraction of landmarks from digital documents, however, has not been fully explored. The World Wide Web provides a rich source of region related information based on our understanding of geographic space. W...

Key Points • Palpation of functional cranial tibial thrust instability during weight-bearing is used to assess knee stability preand post-operatively. • Variation in radiographic landmarks to determine stifle flexion angle (SFA) leads to variable TTA cage size recommendations. Use of the Long Axes Method leads to larger advancement recommendations than Kinematic or Eminence Methods. • Variation...

The use of visual landmarks for robot navigation is a promising eld. It is apparent that the success of navigating by visual landmarks depends on the landmarks chosen. This paper reviews a monocular camera system proposed by Bianco and Zelinsky, 1999] which automatically selects landmarks and uses them for lo-calisation and navigation tasks. The monocular system's landmark selection policy resu...

We describe an efficient method for localizing a mobile robot in an environment with landmarks. We assume that the robot can identify these landmarks and measure their bearings relative to each other. Given such noisy input, the algorithm estimates the robot’s position and orientation with respect to the map of the environment. The algorithm makes efficient use of our representation of the land...
