Flynn, John J. | Antitrust jurisprudence: a symposium on the economic, political and social goals of antitrust policy | Felix S. Cohen has observed that [a]n ethics, like a metaphysics, is no more certain and no less dangerous because it is unconsciously held. There are few judges, psychoanalysts, or economists today who do not begin a consideration of their typical problems with some formula designed to cause all m... | Efficiency; Analysis ; Assumptions | 1977 |

Boll, Steven F. | Application of the saber method for improved spectral analysis of noisy speech | A stand alone noise suppression algorithm is described for reducing the spectral effects of acoustically added noise in speech. A fundamental result is developed which shows that the spectral magnitude of speech plus noise can be effectively approximated as the sum of magnitudes of speech and noise.... | Noise suppression algorithm; SABER method | 1977 |

Davis, A.L. | The architecture of DDMl: a recursively structured data driven machine | An architecture for a highly modular, recursively structured class of machines is presented. DDMl is an instance of such a machine structure, and is capable of executing machine language programs which are data driven (data flow) nets. These nets may represent arbitrary amounts of concurrency as wel... | DDMl; machine structure; machine language programs | 1977 |

Hawkes, Kristen | Assignment of relationship terms in Binumarien | Kinship systems have a perennial fascination. From Morgan's day to the present, a long succession of authors have produced their diagrams and algebraic explanations . . . Kinship terminology and its diagramatic arrangements provide, ready made, a delightful series of mathematical abstractions and it... | Binumarien; Binumariens | 1977 |

Lindstrom, Gary E. | Backtracking in generalized control settings | Backtracking is a powerful conceptual and practical technique in programming. However, its application in general has been limited to global control over recursive programs. In this paper we explore through several examples the coherence and utility of applying backtracking in more general control s... | Backtracking | 1977 |

Gesteland, Raymond F. | Cell-free synthesis of herpes simplex virus proteins | Polyribosomes isolated from herpes simplex virus type I (HSV-1)-infected cells have been used to program a eucaryotic cell-free translation system. At least 10 HSV-specific polypeptides, with apparent molecular weights of 25,000 to 160,000, are synthesized by wild-type HSV-infected polyribosomes. Po... | Viral Proteins; Herpes Simplex; Peptide Biosynthesis; Thymidine Kinase | 1977 |

Hartmann, Donald P. | Considerations in the choice of interobserver reliability estimates | Two types of interobserver reliability values may be needed in treatment studies in which observers constitute the primary data-acquisition system: trial reilability and the reliability of the composite unit or score which is subsequently analyzed, e.g., daily or weekly session totals. Two approache... | Observational technology; Reliability; Validity; Statistics; Recording and measurement techniques; Cohen's kappa; Generalizability theory; Measurement theory; Spearman-Brown prophesy formula; Correlational measures | 1977 |

Lindstrom, Gary E. | CONSIM: a converstional simulation language implemented through interpretive control self-modeling | This paper describes an implementation technique termed interpretive control self-modeling (ICSM) and outlines its application in the implementation of CONSIM, a prototype conversational simulation language. ICSM may be defined as the use of a higher-level programming language (HLL) to specify its o... | CONSIM; Converstional simulation language; Interpretive control self-modeling; ICSM | 1977 |

Keller, Robert M. | Denotational models for parallel programs with indeterminate operators | Several approaches to networks of concurrently-operating modules involving indeterminacy are discussed. Techniques for representing the denotational semantics of such networks, and for verifying properties of them, are presented, including an oracle approach, an axiomatic approach, a data-type reduc... | Denotational models; Indeterminate operators | 1977 |

Dintelman, Sue Marie Thompson | Design and implementation of a relational data base system for a minicomputer | A data base system provides the advantages of centralized control of data including increased data independence. Design specifications for a low level relational data base interface are given in the form of a formal description which separates the implementation details from the description of the ... | Data base system | 1977 |

Faugeras, Olivier Dominique | Digital color image processing and psychophysics within the framework of a human visual model | A three-dimensional homomorphic model of human color vision based on neurophysiological and psychophysical evidence is presented. This model permits the quantitative definition of perceptually important parameters such as brightness. saturation, huo and strength. By modelling neural interaction in t... | Human visual model; Neurophysiological evidence; Psychophysical evidence | 1977 |

Lindstrom, Gary E. | Efficiency in nondeterministic control through non-forgetful backtracking | Nondeterministic (ND) control has long been used to express elegant solutions to complex search problems. Programs using ND control can be executed on conventional machines through a systematic examination of trial execution paths. Among the many approaches to the enumeration of these paths is backt... | Nondeterministic control; Non-forgetful backtracking; Search problems | 1977 |

Armentrout, Peter B. | Endothermic reactions of uranium ions with N2, D2, and CD4 | The assessment of new technology for isotope separation has revived an interest in the spectroscopy, properties, and reactions of uranium and its compounds. Newer methods which have been demonstrated include the use of lasers to selectively excite a particular uranium isotope with subsequent chemic... | Uranium ions; Nitrogen | 1977 |

Davidson, Diane W. | Foraging ecology and community organization in desert seed-eating ants | Granivorous ants in the southwestern deserts of the United States are characterized by species-specific colony foraging behaviors that determine their efficiencies at utilizing seeds from different density distributions. Workers search for food either in groups or as individuals, and these feedin... | Ants; Arizona; California; Coexistence; Communities; Density specialization; Desert granivores; Foraging strategies; Insects; New Mexico; Resource partitioning | 1977 |

McDonald, Lee Edwin | Image recognition using generalized correlation | This paper investigates the use of generalized cross-correlation in pattern matching when the objects may be of one or two dimensions. Generalized correlation can be used to determine the amount of dilatation and rotation between a given template and an object, in addition to determining the relativ... | Image recognition; Generalized correlation | 1977 |

Boll, Steven F. | Improving linear prediction analysis of noisy speech by predictive noise cancellation | The analysis of speech using Linear Prediction is reformulated to account for the presence of acoustically added noise and a technique is presented for reducing its effect on parameter estimation. The method, called Predictive Noise Cancellation (PNC), modifies the noisy speech autocorrelations ... | Linear prediction; Predictive Noise Cancellation; Noisy speech; Sppech analysis | 1977 |

Capecchi, Mario R. | Isolation of a suppressible nonsense mutant in mammalian cells | An HGPRT- cell line derived from mouse L cells has been shown to have the following properties: it is CRM'; the defective HGPRT molecules are altered in the carboxyterminal peptide; the mutant cells regain HGPRT activity when ochre-suppressor tRNA is microinjected into them, but not when amber... | HGPRT cell line; HGPRT activity; Ochre nonsense mutation; Mouse L cells; Mammalian cells | 1977 |

Stringfellow, Gerald B. | Mechanism for liquid phase epitaxial growth of nonequilibrium compositions producing a coherent interface | A model is presented for growth by so-called composition pulling, wherein an epitaxial deposit grows coherently but with a composition different from that which would be in bulk equilibrium with the liquid phase from which growth occurs.
