Olivera, Baldomero M. | Aminoglycoside effects on voltage-sensitive calcium channels and neurotoxicity | To the Editor: Since ototoxicity and neuromuscular toxicity of aminoglycoside antibiotics are reversed by calcium, 1,2 and presynaptic events appear to be involved in aminoglycoside-induced neuromuscular blockade, 3,4 we suspected a role for voltage-sensitive calcium channels in aminoglycoside neuro... | Conotoxins | 1987 |

Gardner Michael K. | Word-frequency effect in lexical decision: finding a frequency-based component | Subjects making lexical decisions are reliably faster in responding to high-frequency words than to low-frequency words. This is known as the word frequency effect. We wished to demonstrate that some portion of this effect was due to frequency differences between words rather than to other dimensio... | Stimulus; Interaction; Variance | 1987 |

Pershing, David W. | Control of NOx and particulate emissions from spreader-stokers fired with hogged wood | The formation and emission of nitrogen oxides and particulate carry-over were studied from spreader-stoker combustion of hogged Douglas-fir, with a focus on optimizing the combustion conditions in each of the two distinct combustion zones, the bed phase and the suspension phase local oxygen availabi... | Chemical analysis; Combustion; Emission; Engineering; Environmental control; Fuels; Nitrogen compounds; Particulates; NOx; Hogged wood | 1987 |

Poulter, Charles Dale | Trisammonium geranyl diphosphate | Geranyl chloride. To a flame-dried, 100-mL, three-necked, round-bottomed flask equipped with a magnetic stirrer, low temperature thermometer, rubber septum, and nitrogen inlet adapter, is added 1 .47 g (11 mmol) of N-chlorosuccinimide (Note 1) . The powder is dissolved in 45 mL of dry dichloromet... | Buffer; Solution; Chloride | 1987 |

Mathews, V. John | Improved convergence analysis of stochastic gradient adaptive filters using the sign algorithm | Abstract-Convergence analysis of stochastic gradient adaptive filters using the sign algorithm is presented in this paper. The methods of analysis currently available in literature assume that the input signals to the filter are white. This restriction is removed for Gaussian signals in our analysis... | 1987 | |

Fujimoto, Richard M. | Optimal performance of distributed simulation programs | This paper describes a technique to analyze the potential speedup of distributed simulation programs. A distributed simulation strategy is proposed which minimizes execution time through the use of an oracle to control the simulation. Because the strategy relies on an oracle, it cannot be used for ... | Distributed simulation programs | 1987 |

Henderson, Thomas C. | Apparent symmetries in range data | A procedure for extracting symmetrical features from the output of a range scanner is described which is insensitive to sensor noise and robust with respect to object surface complexity. The acquisition of symmetry descriptors for rigid bodies from a range image was in this case motivated by the ne... | Symmetry descriptors; Range data; Range scanner; Dextrous manipulation systems | 1987 |

Mathews, V. John | Adaptive filters requiring zero multiplications | This paper introduces an adaptive filter structure that requires zero multiplications for its implementations. The primary input signals are quantized using DPCM and the DPCM outputs are processed by the adaptive filter. The sign algorithm. We show that if the parameters are chosen properly, hardwar... | 1987 | |

Symko, Orest George | Spatial Fourier transform method for evaluating SQUID gradiometers | A simple method of measuring the spatial transfer function of a gradiometer, consisting of a flux transformer coupled to a SQUID, is presented and it is compared with theoretical predictions. Based, on this approach, a new method of reporting a gradiometer's performance is proposed; the rejection fa... | Spatial Fourier transform; SQUID gradiometers; Evaluation; Spatial transfer function | 1987 |

Miller, Jan D. | Fluoride activation in oleate flotation of collophanite | Fluoride activation has been evaluated by Hallimond tube flotation of collophanite in terms of fluoride concentration, conditioning time, pH, and temperature. The results reveal that efficient oleate flotation of collophanite can be achieved by fluoride activation. Experimental results of fluoride... | Fluoride; Oleate; Collophanite; Flotation; Calcium; Chemisorption | 1987 |

Olivera, Baldomero M. | Biochemical studies of ω-conotoxin GVIA; a peptide toxin inhibiting voltage-sensitive Ca++ channels | The fish-hunting cone snails use their venom to quickly paralyze their more agile prey. In the last few years, our laboratories have carried out a program of analyzing biologically active components present in the fish-hunting cone snail venoms (Cruz et al. 1985; Olivera et al. 1985). We have concen... | Conotoxins; Calcium channels; Conus geographus; Venom | 1987 |

Mathews, V. John | Image compression using vector quantization of linear (One-Step) prediction errors | ABSTRACT A novel approach to image compression using vector quantization of linear (one-step) prediction errors is presented in this paper. In order to minimize the image reconstruction error, we choose the optimum predictor coefficients (in a least-squares sense) that satisfy the additional constr... | 1987 | |
