1476 Riloff, Ellen M.Conundrums in noun phrase coreference resolution: making sense of the state-of-the-artWe aim to shed light on the state-of-the-art in NP coreference resolution by teasing apart the differences in the MUC and ACE task definitions, the assumptions made in evaluation methodologies, and inherent differences in text corpora. First, we examine three subproblems that play a role in coref...Noun phrase; Coreference resolution; MUC; ACE2009
1477 Olivera, Baldomero M.; Gray, William Robert; Yoshikami, DojuConus geographus toxins that discriminate between neuronal and muscle sodium channelsWe describe the properties of a family of 22-amino acid peptides, the μ-conotoxins, which are useful probes for investigating voltage-dependent sodium channels of excitable tissues. The μ-conotoxins are present in the venom of the piscivorous marine snail, Conus geographus L. We have purified even...Conus geographus; Venom; Conotoxins; Sodium channels; Neurotoxins1985
1478 Olivera, Baldomero M.; McIntosh, J. MichaelConus peptides as tools for the neuroscientistRecombinant DNA technology has had a powerful impact on understanding receptors and ion channels, the key components in the nervous system that are involved in intercellular communication. Cloning genes encoding these proteins has revealed that for every receptor and ion channel type, multiple molec...Conus peptides; Conotoxins1993
1479 Olivera, Baldomero M.Conus peptides: biodiversity-based discovery and exogenomicsThe venoms of the ~700 species of predatory cone snails (genus Conus) are being systematically characterized. Each Conus species contains 100-200 small, highly structured venom peptides (colloquially known as conotoxins), which are synthesized and secreted in a venom duct (for overviews, see Refs. ...Conotoxins; Conus peptides; Exogenomics2006
1480 Olivera, Baldomero M.Conus peptides: phylogenetic range of biological activityThe major function of the venoms of the predatory marine snails belonging to the genus Conus is to paralyze prey. Thus, the venom of each Conus species acts on receptors and ion channels of the prey; previous studies suggested much less activity on homologous receptor targets in more distant taxa....Conus peptides; Conopeptides; Conotoxins1992
1481 Olivera, Baldomero M.Conus venom peptides, receptor and ion channel targets, and drug design: 50 million years of neuropharmacologyThe predatory cone snails (Conus) are among the most successful living marine animals (~500 living species). Each Conus species is a specialist in neuropharmacology, and uses venom to capture prey, to escape from and defend against predators and possibly to deter competitors. An individual cone...Conotoxins1997
1482 Miller, Joel StevenConvenient synthesis of C5(CD3)5H. synthesis and characterisation of Fe{n5-C5(CD3)5}2The large scale synthesis of deuterio(pentamethylcyclopentadiene), C5(CD3)5H ([2H30]Cp*H), and subsequent synthesis of [2H30][Fe(n|-Cp*)2] is described, together with i.r., Raman, and solid state 2H n.m.r. spectroscopic characterisation.Organometallic; Catalytic1988
1483 Yu, Zhou; Myers, DowellConvergence or divergence in Los Angeles: three distinctive ethnic patterns of immigrant residential assimilationThis paper uses census microdata to examine five aspects of residential assimilation in the greater Los Angeles area. A double cohort method is used to separate the effect of duration in the U.S. from the effect of aging. We track a single arrival cohort that came in 1970-79, and analyze the process...Residential assimilation; Immigrants; Cohort; Los Angeles; Homeownership2006-01-11
1484 Golden, Kenneth M.Convexity and exponent inequalities for conduction near percolationThe bulk conductivity o*(p) of the bond lattice in Zd with a fraction p of conducting bonds is analyzed. Assuming a hierarchical node-link-blob (NLB) model of the conducting backbone, it is shown that o*(p) (for this model) is convex in p near the percolation threshold pc, and that its critical expo...Lattice; Conductivity; Model1990
1485 Golden, Kenneth M.Convexity in random resistor networksThe bulk conductivity o*(p) of the bond lattice in Zd is considered, where the conductivity of the bonds is either 1 with probability p or e > 0 with probability 1 - p. Rigorous and non-rigorous results demonstrating convexity of o*(p) near the percolation threshold pc are presented.Conductivity; Bond lattice; Critical exponent t1989
1486 Vardeny, Zeev ValentineCooperative and stimulated emission in poly(p-phenylene-vinylene) thin films and solutionsWe discuss cooperative and stimulated emissions and separate their respective contributions to the emission spectral narrowing in thin films and solutions of poly(p-phenylene-vinylene) derivatives. Whereas cooperative radiation is favored in films with poor optical confinement, directional stimula...pi-conjugated polymers; PPV; Spectral narrowing1998-04
1487 Vardeny, Zeev Valentine; Raikh, Mikhail E.Cooperative emission from a disordered system: a classical modelThe effect of disorder on the collective emission from a system of classical oscillators is studied theoretically. Three types of disorder are considered: random orientation of dipole moments, finite spread in frequencies of the individual oscillators (diagonal disorder), and dipole-dipole interacti...Cooperative emission; Disordered system; Dipole-dipole interaction; Oscillators1997
1488 Vardeny, Zeev ValentineCooperative emission in ∏-conjugated polymer thin filmsPicosecond dynamics of exciton emission and absorption have been studied in neat thin films of a variety of poly (phenylene vinylene) derivatives. We found that the stimulated emission band of 120 nm width and ~1 ns duration, which is observed at low exciton density n, collapses at n > 1017 cm-3 int...Pi-conjugated polymers; Poly (phenylene vinylene) derivatives; PPV derivatives; Cooperative emission1997-01
1489 Johnston, Susan S.Coordinating preservice and in-service training of early interventionists to serve preschoolers who engage in challenging behaviorThis chapter focuses on the need to coordinate and improve preservice and in-service training (including technical assistance) for professionals who serve individuals and family members who live or work with young children who engage in challenging behavior. Positive behavioral support: includin...Behavior problems; Proactive strategies; Intervention strategies1996
1490 Goller, FranzCoordination and synergism between visual and vocal display in the brown-headed cowbirdsSexually selected acoustic signaling is accompanied by visual displays in many birds. The motor integration of visual and vocal displays has not been extensively studied. Brown-headed cowbirds (Molothrus ater) "puff up" prior to song, move their wings during the song and conclude with a bow. The ...Acoustic signaling; Wing display; Synergistic interaction2003

1497 Riloff, Ellen M.Corpus-based approach for building semantic lexiconsSemantic knowledge can be a great asset to natural language processing systems, but it is usually hand-coded for each application. Although some semantic information is available in general-purpose knowledge bases such as Word Net and Cyc, many applications require domain-specific lexicons that repr...Corpus-based method; Semantic lexicons1997
1498 Riloff, Ellen M.Corpus-based bootstrapping algorithm for semi-automated semantic lexicon constructionMany applications need a lexicon that represents semantic information but acquiring lexical information is time consuming.

Our algorithm uses a representative text corpus for ...Bootstrapping algorithm; Lexicon construction1999-06
1499 Riloff, Ellen M.Corpus-based identification of non-anaphoric noun phrasesCoreference resolution involves finding antecedents for anaphoric discourse entities, such as definite noun phrases. But many definite noun phrases are not anaphoric because their meaning can be understood from general world knowledge (e.g., "the White House" or "the news media"). We have develope...Corpus-based identification; Non-anaphoric noun phrases; Coreference resolution; MUC-4; Discourse entity; DE1999
