Olivera, Baldomero M. | Poly(ADP-ribosylation) of DNA topoisomerase I: a nuclear response to DNA-strand interruptions | DNA in eukaryotic chromosomes is organized differently from prokaryotic DNA. It seems highly probable that mechanistic adjustments have been made in macromolecular DNA metabolism as a consequence of the chromatin structure of the eukaryotic chromosome (Igo-Kemenes et al. 1982)). This paper deals ... | Poly(ADP-ribosylation); Poly(ADP-ribose) synthetase; DNA strand interruption | 1984 |

Bhanu, Bir | Representation and shape matching of 3-D objects | A three-dimensional scene analysis system for the shape matching of real world 3-D objects is presented. Various issues related to representation and modeling of 3-D objects are addressed. A new method for the approximation of 3-D objects by a set of planar faces is discussed. The major advantage of... | 3-D objects; Representation; Shape matching; Scene analysis system | 1984 |

Olson, Randall J.; Coldwell, Karin D.; Compton, Bruce J.; Giddings, John C. | Sedimentation field-flow fractionation: a method for studying particulates in cataractous lens | It is shown that the technique of sedimentation field-flow fractionation (sedimentation [sed] FFF) can be used to determine the particle content and particle size distribution of normal and cataractous lenses. A 31-year-old normal human lens, for example, showed a particle content of 1.5% by weight ... | Fractionation; Cataractous Lens; Particulates | 1984 |

Miller, Jan D. | Selectivity considerations in the amine extraction of gold from alkaline cyanide solutions | It has been discovered that gold can be extracted from alkaline cyanide solution with primary, secondary, and tertiary amines by adding certain Lewis base modifiers, such as organic phosphorus oxides. Under these circumstances, gold can be extracted at about pH 10, commensurate with the pH of cyan... | Gold; Amines; Alkaline cyanide; Extraction | 1984 |

Keller, Robert M. | Semantics of networks containing indeterminate operators | We discuss a denotational semantics for networks containing indeterminate operators. Our approach is based on modelling a networks by the set of all its possible behaviors. Our notion of behavior is a sequence of computational actions. The primitive computational action is an event: the appearance o... | | 1984 |

Bhanu, Bir | Shape matching of two-dimensional objects | In this paper we present results in the areas of shape matching of nonoccluded and occluded two-dimensional objects. Shape matching is viewed as a "segment matching" problem. Unlike the previous work, the technique is based on a stochastic labeling procedure which explicitly maximizes a criterion ... | Shape matching; Two-dimensional objects; Segment matching | 1984 |

Miller, Jan D.; Wan, Rong Yu | Significance of carbon properties in the enhanced ferric sulfate leaching of CuFeS2/C aggregates | Acid ferric sulfate solution has been used for heap and dump leaching of low-grade chalcopyrite ores and is being considered as a possible lixiviant for the hydrometallurgical processing of copper sulfide concentrates. For many years, researchers have attempted to explain the leaching behavior of ch... | Ferric sulfate; CuFeS2; Particulate carbon | 1984 |

Pickett, Forrest B. | Simulation of Cells | A self-timed cell set and library for the design of integrated circuits is presented. The cell set and library are two different cellular methods of designing integrated circuits. These have been incorporated to form a hybrid system which exploits the advantages provided by each. The cell set an... | Self-timed; Cell set | 1984 |

Mathews, V. John | Spectral leakage suppression properties of linear and quadratic windowing | Abstract-It is shown that the leakage suppression properties of segment averaging spectrum estimation methods using hear windows and equivalent quadratic windows are asymptotically the same, under the assumption that segments relatively far apart are uncorrelated. Thus, for large data lengths, one ... | | 1984 |

Mattis, Daniel C. | Three-body bound states on a lattice | The theory of three-body bound states for particles moving on a lattice and interacting with attractive two-body pointlike potentials is presented. The applications are to bosons, fermions (no three-body bound states are found), and magnons. When a three-body bound state forms in three dimensions, i... | Particle; Fermions; Ferromagnet | 1984 |

Armentrout, Peter B. | Threshold behavior of endothermic reactions: C+(2P) + H2 → CH+ + H | The reaction C+(2p) + H2 → CH+ + H (1) and its deuterium analog is a model system in ion-molecule chemistry. It is of interest due to its astrophysical significance, because it is an endothermic process, and because the interaction involves several potential energy surfaces. Experimental work ha... | Endothermic reactions; Translational energy; Threshold behavior | 1984 |

In 1983 a breeding place was discovered near Lavant in about 650 m NN. Feeding adults were watched on the 11th and 12th of August. The breeding place is briefly desc... | Merops apiaster; Meropidae; Tyrol | 1984 |

Mattis, Daniel C. | What is the effective mass of an exciton? | In the effective-mass approximation, the mass M* of an exciton is just the sum of the electron and hole masses, me*+ mh*. However, the effective-mass approximation is invalid if the forces are strong. Here we derive a plausible formula for the n th bound state of the exciton: Mn*= (me* + mh*) / (... | Kinetic; Energy; Electron | 1984 |

Olivera, Baldomero M.; McIntosh, J. Michael; Gray, William Robert | γ-Carboxyglutamate in a neuroactive toxin | The venom of a fish-hunting cone snail (Conus geographus) contains a novel toxin, the "sleeper" peptide, which induces a sleep-like state in mice when injected intracerebrally. We demonstrate that this peptide contains 5 mol of γ-carboxyglutamate (Gla) in 17 amino acids. The amino acid sequence o... | Conus geographus; Venom; Conotoxins; gamma-Carboxyglutamate; Neurotoxins | 1984 |
