Touching from a distance
The nuclear pore complex (NPC) is the sole mediator of bidirectional nucleo-cytoplasmic transport and is also an important scaffold for chromatin organization and transcriptional regulation. Proteomic studies of numerous diverse eukaryotic species initially characterized the NPC as built with a number of remarkably similar structural features, suggesting its status as an ancient and conserved e...
متن کاملSeparation of Touching Text from Graphics
The separation of intersecting text from graphics is a challenging problem in document image analysis. This paper proposes a specific method of detecting and extracting characters that are touching graphics. It is based on the observation that the constituent strokes of characters are usually short segments in comparison with those of graphics. It combines line continuation with the feature lin...

The connection between one aspect of understanding one's surroundings, and the eyes, is developed: vision is not reality. The different perception of an object ...
متن کاملTouching geometry
Geometric models and algorithms have been traditionally designed to support graphics, visualization, and spatial reasoning. Recent developments in human computer interfaces are now making it possible to \touch" virtual geometric objects | we can feel interaction forces with haptic interfaces and hear realistic contact sounds with auditory displays. These interfaces pose new challenges for the d...
متن کاملA Touching Picture of Nicotinic Binding
The snail acetylcholine binding protein (AChBP) is homologous to the extracellular domains of the nicotinic ACh receptors. In this issue of Neuron, Celie et al. show how the crystal structures of AChBP in complexes with carbamylcholine and nicotine reveal the basis for agonist recognition by ACh receptors.
