Several discrete transitions are reported in the energy range from 18 400 to 19 100 cm-?. Most of these are... | 1994 | |

Morse, Michael David | Interaction of an aluminum atom with an alkaline earth atom: spectroscopic and ab initio investigations of AICa | A spectroscopic analysis of diatomic AlCa generated by laser vaporization of a 2:1 AI:Ca metal alloy followed by supersonic expansion has been completed using resonant two-photon ionization spectroscopy. Four excited electronic states have been identified and investigated in the energy region from 1... | 1994 | |

Parker, Steven G.; Johnson, Christopher R. | Interactive manipulation of contour data using the layers program | The "layers" program is useful for visualizing and editing large sets of contour data. These datasets arise frequently when trying to extract geometry from MRI slices. Due to the imprecise nature of the MR imaging and segmentation processes, the contours extracted may not accurately reflect the huma... | Contour data; Layers program; MRI slices | 1994 |

Kriesel, John D.; Gooch, Willis M.; Pavia, Andrew T. | Invasive sinonasal disease due to Scopulariopsis candida: case report and review of scopulariopsosis. | Sinonasal infection with fungi of the order Mucorales--termed mucormycosis or zygomycosis--is sometimes seen in immunosuppressed patients, including those with diabetic ketoacidosis and malignancy. We describe a case of invasive sinonasal infection with Scopulariopsis candida (not among the Mucorale... | Granulocyte Colony-Stimulating Factor; Itraconazole; Maxillary Sinus | 1994 |

Rogers, Alan R. | Is migration kin structured? | We estimate the strength of kin-structured migration in six human populations (five from New Guinea and one from Finland) and in one population of nonhuman primates. We also test the hypothesis that migration is not kin structured by generating a sampling distribution of the estimator under the null... | 1994 | |

Poulter, Charles Dale | Isoprenyl diphosphate synthases: protein sequence comparisons, a phylogenetic tree, and predictions of secondary structure | Isoprenyl diphosphate synthases are ubiquitous enzymes that catalyze the basic chain-elongation reaction in the isoprene biosynthetic pathway. Pairwise sequence comparisons were made for 6 farnesyl diphosphate synthases, 6 geranylgeranyl diphosphate synthases, and a hexaprenyl diphosphate synthase... | Catalytic site; Evolution; Farnesyl diphosphate; Geranylgeranyl diphosphate; Prenyltransferase; Substrate binding: | 1994 |

Silverman, Randall H. | J. J. Audubon & 19th century color printing | In 1826, the first hand-colored proofs of John James Audubon's double elephant folio edition of The Birds of America were pulled in Edinburgh, Scotland. His life-sized Wild Turkey was among them, transforming the 41 year old naturalist's "innate desire to acquire a thorough knowledge of the birds o... | John James Audubon; Copperplate; Lithograph | 1994 |

Stringfellow, Gerald B. | Kinetically controlled order/disorder structure in GaInP | A Ga0.52In0.58p order/disorder heterostructure having a band-gap energy difference exceeding 160 meV has been grown by organometallic vapor phase epitaxy. The two layers were grown on a nominally (OOl)-oriented GaAs substrate misoriented by 3° toward the [110] direction in the lattice.

Mathews, V. John | Lattice algorithms for recursive least squares adaptive second-order volterra filtering | This paper presents two computationally efficient recursive least-square (RLS) lattice algorithms for adaptive nonlinear filtering based on a truncated second-order Volterra system model. The lattice formulation transforms the nonlinear filtering problem into an equivalent multichannel, linear filte... | 1994 | |

Vardeny, Zeev Valentine | Leng et al. reply | Conwell, Rothberg, and Mizes (CRM) claim [1] that, as a result of chain length distribution and vibronic sidebands of electronic levels in PPV films, there is little correlation between increase of pump photon energy (Hw) and increase of electronic energy, and therefore data from excitation spectros... | Chain length distribution; Vibronic sidebands; PPV films; Pump photon energy | 1994 |

Stringfellow, Gerald B.; Sadwick, Laurence P. | Low pressure pyrolysis of alternate phosphorus precursors for chemical beam epitaxial growth of InP and related compounds | The most widely used phosphorous source in chemical beam epitaxy (CBE) is phosphine (PH3). However, because it is highly toxic, alternatives to phosphine have been sought for the growth of phosphorous-containing compounds. We have investigated the pyrolysis rates and reaction products, in low pres... | Chemical Beam Epitaxy; CBE | 1994 |

Johnson, Christopher R. | Map3d: scientific visualization program for multichannel time series data on unstructured, three-dimensional meshes. program user's guide | There are many examples in biomedical research of recording time signals with multi-sensor arrays whose elements are arranged in irregular, three-dimensional grids [1, 2, 3, 4]. If the nodes in such arrays can be connected into "surfaces", it is possible to employ linear interpolation techniques to ... | Map3D; Multi-sensor arrays; Scientific visualization; Multichannel time series data; Three-dimensional meshes | 1994 |
