Mathews, V. John | Vector quantization using the L∞ distortion measure | Abstract-This paper considers vector quantization of signals using the L1 distortion measure. The key contribution is a result that allows one to characterize the centroid of a set of vectors for the L1 distortion measure. A method similar to the Linde-Buzo-Gray (LBG) algorithm for designing codeboo... | 1997 | |

Coley, Phyllis D. | Vesicular-arbuscular mycorrhizae in two tropical monodominant trees | Mycorrhizae, symbioses between plant roots and fungi, are found in virtually all terrestrial plant ecosystems. Substantial evidence indicates that mycorrhizal associations are beneficial to both partners. | Ectromycorrizae; Flooding; Monodominance; Neotropics; Vesicular-arbuscular mycorrhizae; Mora excelsa; Prioria copaifera | 1997 |

Torti, Sylvia D.; Coley, Phyllis D. | Vesicular-arbuscular mycorrhizae in two tropical monodominant trees | Mycorrhizae, symbioses between plant roots and fungi, are in virtually all terrestrial plant ecosystems. Substantial evidence indicates that mycorrhizal associations are beneficial to both partners. In most systems, the fungus benefits the host plant by effectively scavenging nutrients and in return... | Monodominance; Ectomycorrhizae; Flooding; Neotropics; Vesicular-arbuscular mycorrizae; Mora excelsa; Prioria copaifera | 1997 |

Henderson, Thomas C. | Visual target based wall pose estimation | We compare vision and sonar techniques for the recovery of wall pose. A vision algorithm is developed which is based on known target geometry, and a sonar technique based on a wedge model is described. | wall pose; vision algorithm; wedge model | 1997 |

Kessler, Robert R. | Visual threads: the benefits of multithreading in visual programming languages | After working with the CWave visual programming language, we discovered that many of our target domains required the ability to define parallel computations within a program. CWave has a strongly hierarchical model of computation, so it seemed like adding the ability to take a part of the hierarchy ... | Visual threads; multithreading; CWave | 1997 |

Goller, Franz | Vocal gestures of shared syllable types in cardinals | In songbirds, songs are learned by memorization and copying of tutor song and such copies can be remarkably accurate. However, it is not known whether acoustic similarity is generated by equally similar vocal gestures. We studied syringeal and respiratory motor patterns of syllable types shared by u... | Cardinalis cardinalis; Vocal gestures; Birdsong syllables; Song syllables | 1997 |

Olivera, Baldomero M.; McIntosh, J. Michael | α-Conotoxin MII blocks nicotine-stimulated dopamine release in rat striatal synaptosomes | Activation of presynaptic nicotinic acetylcholine receptors (nAChRs) can induce the release of neurotransmitters such as dopamine and norepinephrine in the CNS. Accumulating evidence suggests that distinct nAChR subtypes are involved; however, it has been difficult to determine the subunit composit... | Conotoxins; a-Conotoxin MII | 1997 |
