Miller, Joel Steven; Epstein, Arthur J. | Linear chain ferromagnetic charge transfer compounds | Charge transfer complexes possessing a ... DADA ... structure with both the donor, D, and acceptor, A, being S = 1/2 radicals may exhibit cooperative magnetic phenomena. The complex [Fe(C5Me5)2]+ [TCNQ]-. exhibits metamagnetic behavior.

Brown, Francis Harold | Magnetostratigraphy of the Koobi Fora Formation, Lake Turkana, Kenya | The Koobi Fora Formation, a Pliocene and Pleistocene sequence of sedimentary deposits northeast of Lake Turkana, has yielded numerous fossils and stone artifacts of early hominids. Stratigraphic correlation of the hominid-bearing deposits throughout the Turkana region was established primarily by th... | 1986 | |

Miller, Jan D. | Methodology for detailed liberation analysis in mineral processing technology | A transformation equation can be used to describe the relationship between the one, two and three dimensional information regarding the composition of mineral particles of specified size. Linear or areal grade distributions f(gi) can be transformed to an estimate of the volumetric grade distribution... | Volumetric grade; Grade; Distribution | 1986 |

Rogers, Alan R. | Migration and genetic drift in human populations | In humans and many other species, mortality is concentrated early in the life cycle, and is low during the ages of dispersal and reproduction. Yet precisely the opposite is assumed by classical population-genetics models of migration and genetic drift. We introduce a model in which population regul... | Frequencies; Variance; Dynamics | 1986 |

Jorgensen, Erik | Multiple transcripts from the Antennapedia gene of Drosophila melanogaster | The structures of four major transcripts from the homeotic gene Antennapedia of Drosophila melanogaster were determined. These transcripts constitute two RNA classes, each class initiating from a unique promoter but sharing 3' exons. Within the shared sequences is a major open reading frame encoding... | Mutations; Sequences ; RNA | 1986 |

Henderson, Thomas C. | Multisensor knowledge systems | We describe an approach which facilitates and makes explicit the organization of the knowledge necessary to map multisensor system requirements onto an appropriate assembly of algorithms, processors, sensors, and actuators. We have previously introduced the Multisensor Kernel System and Logical Sen... | Multisensors; Multisensor Kernel System; Multisensor systems | 1986 |

Clayton, Dale H. | Neotropical tineidae, II: biological notes and descriptions of two new moths phoretic on spiny pocket mice in Costa Rica (Lepidoptera: Tineoidea) | Two new species of tineid moths discovered riding on the backs of two species of spiny pocket mice (Heteromyidae) in Costa Rica are described. Amydria selvae, new species, was found on Heteromys desmarestianus Gray in the rainforest at Finca La Selva and Ptilopsaltis santarosae, new species, occurr... | Neotropical Tineidae; Phoretic moths; Amydria selvae; Heteromys desmarestianus; Ptilopsaltis santarosae; Liomys salvini; Mouse moths | 1986 |

Ailion, David Charles | Nuclear magnetic resonance in random fields: cluster formation and local dynamics of a deuteron glass | NMR data show that the deuteron "pseudo spin-glass" transition in Rbi- X(ND4)*D2P04 is not just a simple kinetic slowing down process but is characterized by a gradual condensation of randomly polarized clusters as expected if we deal with a percolation transition in eigenstate space. The results pr... | NMR; Nuclear magnetic resonance; Random fields; Spin lattice | 1986 |

Vardeny, Zeev Valentine | Observation of molecular vibrations in real time | In a recent Letter Rosker, Wise, and Tang1 have reported ultrafast optical measurements on two large dye molecules, malachite green and nile blue 690. Using the transmission-correlation technique with 40-fs light pulses, they measured photoinduced changes in optical transmission and found a resp... | Molecular vibrations; Nile blue 690; Dyes | 1986 |

Fujimoto, Richard M. | On synthesizing systolic arrays from recurrence equations with linear dependencies | We present a technique for synthesizing systolic architectures from Recurrence Equations. A class of such equations (Recurrence Equations with Linear Dependencies) is defined and and the problem of mapping such equations onto a two dimensional architecture is studied. We show that such a mapping is ... | Recurrence equations | 1986 |

Vardeny, Zeev Valentine | Optical modulation spectroscopy of a-Si:H based multilayer structures | Steady state optical modulation spectrum of a-Si:H/a-SiNx:H multilayer structure, its temperature dependence and time decay have been studied. For multilayers with very thin sublayers the onset of the spectrum is more gradual and occurs at higher energy than the spectrum for unlayered a-Si:H, indic... | Optical modulation spectroscopy; a-Si:H; Amorphous silicon; Dangling bonds | 1986 |

Williams, Clayton C. | Optical ranging by wavelength multiplexed interferometry | A new optical technique is described for measurement of absolute distance. The approach is based upon a wavelength multiplexed heterodyne interferometer with FM demodulation. By temporally multiplexing discrete wavelengths in a heterodyne interferometer, a complete elimination of interferometric ra... | Optical ranging; Distance | 1986 |

Landesman, Bruce M. | Physician attitudes toward patients | An 8-year-old child with a minor head injury is brought in to the emergency department and is judged by the physician to be completely normal. The parents say that a sibling had a skull fracture under similar circumstances and that they would sleep much better if a skull x-ray were taken.

Vardeny, Zeev Valentine | Picosecond dynamics of photoexcitations in amorphous multilayer structures | We report on measurements of ultrafast relaxation processes in transmission and reflection in amorphous multilayer structures consisting of a-Si:H, a-SiNx:H, a-SiOx:H, and a-Ge:H. The decays recorded in transmission in the a-Si:H/a-SiNx :H and a-Si:H/a-SiOx :H multilayers depend strongly on the sili... | Photoexcitations | 1986 |

Francis, John G. | Public lands institutions and their discontents | The history of the federal lands has been marked by recurring debates over the nature of the land tenure system in the West. The fundamental and enduring nature of these debates has been quite apparent recently, for serious attention has been paid to the following specific proposals. Should the owne... | Federal lands; United States | 1986 |

Francis, John G.; Francis, Leslie P. | Rationing of health care in Britain: an ethical critique of public policy-making | IN BRITAIN, as in the United States, rationing of health care is a fact of life and death. Some rationing is overt, such as the Stanford heart transplant program's decision not to accept very young or older patients.1 Some is disguised, such as day-to-day decisions in hospitals about "do not resusci... | Rationing; National Health Service | 1986 |

White, Nicholas P. | Rulers' choice | Plato undertook in the Republic to show that "it is in every way better to be just than unjust" (Book II, 357b1 -- 2). What did he mean by this? I would like to focus on two relevant questions. 1) Did he believe that invariably the more just a person is, the better it is for him? We should prefer t... | Republic; Plato; Justice | 1986 |
