 | Morse, Michael David | Predissociation lifetimes of vibrational levels of the excited ? B? (Ka=O) electronic states of Cd ? H? and Cd ? D? complexes | The experimental rates of predissociation of vibrational levels of the ?B? (K'a-O) excited states of the Cd ? HZ and Cd ? D2 complexes are shown to be consistent with both semiclassical and quantum-mechanical pseudodiatomic theoretical treatments of the process. The ?B? pseudodiatomic potential was ... | 1992 | |

 | Baehr, Wolfgang | Primary structure and chromosomal localization of human and mouse rod photoreceptor cGMP-gated cation channel | We have determined the primary structures of the human and mouse retinal rod cGMP-gated cation channel by analysis of cDNA clones and amplified DNA. The open reading frames predicted polypeptides of 690 and 683 residues exhibiting 88% sequence similarity. Sequence comparison indicated that the rod c... | Restriction Mapping; Sequence Homology, Nucleic Acid; Chromosomes, Human, Pair 4 | 1992 |

 | The programming language jigsaw: mixins, modularity and multiple in heritance | This dissertation provides a framework for modularity in programming languages. In this framework known as Jigsaw, inheritance is understood to be an essential linguistic mechanism for module manipulation. In Jigsaw, the roles of classes in existing languages are "unbundled," by providing a suit... | Jigsaw framework; Mixins | 1992 | |

 | Couldwell, William T. | Protein kinase C activity correlates with the growth rate of malignant gliomas: Part II. Effects of glioma mitogens and modulators of protein kinase C | THE PROLIFERATION RATES of gliomas may be modulated by the protein kinase C (PKC) signal transduction system. The present study was undertaken to further examine the role of PKC system in growth regulation of gliomas in vitro by measurement of PKC activity over various phases of tumor growth and by ... | Protein kinase C; Brain neoplasms; Growth factor; Glioma; Phorbol ester | 1992 |

 | Mathews, V. John | QR-decomposition based algorithms for adaptive volterra filtering | Abstract - In this paper we present a pair of QR-RLS adaptive algorithms for second-order Volterra filtering. The algorithms are based solely on Given's rotations. Hence both the algorithms are numerically stable and highly amenable to parallel implementations. The computational complexity of one of... | 1992 | |

 | Rogers, Alan R. | Quantitative genetics of sexual dimorphism in human body size | A classical data set is used to predict the effect of selection on sexual dimorphism and on the population means of three characters--stature, span, and cubit--in humans. Given selection of equal intensity, the population means of stature and of cubit should respond more than 60 times as fast as d... | Societies; Selection; Species | 1992 |

 | Ehleringer, James R.; Negus, Norman C. | Red Butte Canyon Research Natural Area: history, flora, geology, climate, and ecology | Red Butte Canyon is a protected, near pristine canyon entering Salt Lake Valley, Utah. It contains a well-developed riparian zone and a perennial stream; hillside vegetation ranges from grasslands on the lower limits to Douglas-fir and aspen stands at the upper elevations. In this paper we describe ... | Intermountain West; Grassland; Oak-maple; Plant adaptation; Red Butte Canyon Research Natural Area; Human impact | 1992 |

 | Bruderlin, Beat | Robust boolean set operations for manifold solids bounded by planar and natural quadric surfaces | This paper describes our latest effort in robust solid modeling. An algorithm for set operations on solids bounded by planar and natural quadric surfaces, that handles all geometrically degenerate cases robustly, is described. We identify as the main reason for the lack of robustness in geometric m... | Robust solid modeling; Robust boolean set operations; Manifold solids | 1992 |

 | Bruderlin, Beat | Robustness in geometric modeling - an intuitionistic and tolerance-based approach | An intuitionistic geometry approach is taken to develop two tolerance-based methods for robust geometric computation. The so called analytic model method and the approximated model method are developed independently of a specific application or a geometric algorithm. Geometric robustness is formally... | Robustness; Geometric modeling; Intuitionistic geometry; Geometric robustness | 1992 |

 | Bruderlin, Beat | Robustness in solid modeling - a tolerance based, intuitionistic approach | This paper presents a new robustness method for geometric modeling operations. It computes geometric relations from the tolerances defined for geometric objects and dynamically updates the tolerances to preserve the properties of the relations, using an intuitionistic self-validation approach. Geome... | Solid modeling; Geometric modeling; Intuitionistic | 1992 |
