Myers, Chris J. | Efficient timing analysis algorithms for timed state space exploration* | Abstract This paper presents new timing analysis algorithms for efficient state space exploration during timed circuit synthesis. Timed circuits are a class of asynchronous circuits that incorporate explicit timing information in the specification which is used throughout the synthesis procedure t... | | 1997 |

Francis, Leslie | Elderly immigrants: what should they expect of the social safety net? | The Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (PRWORA) terminated federal benefits to many immigrants. The Balanced Budget Act of 1997 (BBA) only partially restored these benefits to select immigrants who lawfully resided in the United States before August 22, 1996. Pr... | | 1997 |

Horch, Kenneth W. | Electrical stimulation of the ventral lumbo-sacral spinal cord results in mixed recruitment order of quadriceps and tibialis anterior motor units | Pulse width modulated, twitch recruitment curves for quadriceps and tibialis anterior were obtained by stimulating their respective motor activation pools in the ventral lumbo-sacral portion of the spinal cord. The duration of the twitch responses were analyzed as a function of stimulus strength ... | Quadriceps; Tibialis anterior; Ventral lumbo-sacral spinal cord; Reversed recruitment | 1997 |

Golden, Kenneth M. | Electrical transport in high contrast composite materials | A broad range of problems in the physics of materials involve highly disordered media whose effective behavior depends critically on the connectedness, or percolation properties of a particular component. Examples include smart materials such as piezoresistors and thermistors, smart insulators, rada... | | 1997 |

Vardeny, Zeev Valentine | Electromodulated photoinduced absorption; a new spectroscopy in ∏-conjugated polymer/C60-blends | We have applied the electromodulated photoinduced absorption (EPA) technique to a variety of C 6 0 -doped and pristine luminescent conducting polymer films. EPA measures the electric field-related change of the absorption in the sample as a result of above-gap illumination. An electric field leads t... | Electromodulated photoinduced absorption; EPA; C60 doping; Electromodulated photoluminescence; EPL; Polaron pair polarizability | 1997 |

Williams, Clayton C. | Evidence of internal electric fields in GaInP2 by scanning capacitance and near-field scanning optical microscopy | GaInP2 is studied in cross section with the scanning capacitance and near-field scanning optical microscope. Our study shows significant differences in the electronic and optical properties between ordered single- and two-variant GaInP2. In single-variant samples, spatially uniform capacitance signa... | Atomic ordering; transmission electron diffraction; near-field scanning optical microscope | 1997 |

Vardeny, Zeev Valentine | Exciton dynamics in soluble poly(p-phenylene vinylene) | We report studies of poly(2,5-dioctyloxy paraphenylene vinylene) thin films and solutions by a variety of transient, steady state, and nonlinear optical techniques. The energy states and optical absorption of the dominant even and odd parity excitons have been determined.

Davidson, Diane W. | Experimental studies of species-specificity in cecropia-ant relationships | Strict coevolution requires that interactions among organisms be speciesspecific. We assessed the relative roles of host- and habitat-specificity in determining the match between a genus of myrmecophytic trees and a guild of obligate plant-ants in the moist tropical forests of Madre de Dios, Peru.

Angelucci, Alessandra | Experimentally induced retinal projections to the ferret auditory thalamus: development of clustered eye-specific patterns in a novel target | We have examined the relative role of afferents and targets in pattern formation using a novel preparation, in which retinal projections in ferrets are induced to innervate the medial geniculate nucleus (MGN). We find that retinal projections to the MGN are arranged in scattered clusters. Clusters a... | Retina; Ferrets | 1997 |

Sanchez, Thomas W. | Exurban and suburban residents: a departure from traditional location theory | During the 1990s, the exurban landscape grew faster and added more people than urban, suburban, and rural landscapes. In many respects, exurbanization is the quintessential representation of urban sprawl and the problems it poses. More than 100 metropolitan areas across the US attempt to manage exu... | Household location; Exurbanization; Location theory | 1997 |

Flynn, John J. | Flaws in higher education governance are putting the U of U at risk | The governance of colleges and universities has been an enduring source of controversy. At one time or another in the long history of higher education, paramount powers of governance have been claimed by students, faculty, clergy, administrators, boards of regents or trustees, and one or another b... | Institution; University; System | 1997 |

Fernandez, Diego P. | Formulation for the static permittivity of water and steam at temperatures from 238 K to 873 K at pressures up to 1200 MPa, including derivatives and Debye- Hückel coefficients | A new formulation is presented of the static relative permittivity or dielectric constant of water and steam, including supercooled and supercritical states. The range is from 238 K to 873 K, at pressures up to 1200 MPa. The formulation is based on the ITS-90 temperature scale. It correlates a selec... | Static relative permittivity; Dielectric constant | 1997 |

Hawkes, Kristen | Hadza women's time allocation, offspring provisioning, and the evolution of long postmenopausal life spans | Extended provisioning of offspring and long postmenopausal life spans are characteristic of all modern humans but no other primates. These traits may have evolved in tandem.

Kieda, David B. | High statistics search for ultrahigh energy gamma-ray emission from Cygnus X-3 and Hercules X-1 | We have carried out a high statistics (2 X 10 9 events) search for ultrahigh energy g-ray emission from the x-ray binary sources Cygnus X-3 and Hercules X-1. Using data taken with the CASA-MIA detector over a five year period (1990-1995), we find no evidence for steady emission from either source.

Capecchi, Mario R. | Hox genes and mammalian development | We have examined the interactions of Hox genes in forming a cervical vertebrae, hindbrain, and limbs. In each case, it is apparent that individual Hox genes are performing individual functions but that more profound roles are apparent when they act in combination with others Hox genes.

Millgram, Elijah | Hume on practical reasoning (Treatise 463-469) | The claim that " 'is' does not entail 'ought'" is so closely associated with Hume that it has been called 'Hume's Law'.1 The interpretation of the passage in Hume's Treatise of Human Nature that is the locus classicus of the claim is controversial. But the passage is preceded by three main bodies ... | Morality; Human Nature; Deductive | 1997 |

Goller, Franz | Inspiratory muscle activity during singing in zebra finches and cowbirds | Singing is produced by an intricate coordination of vocal (syringeal) and respiratory muscles. Expiratory muscle activity is associated with the production of notes and syllables, which are separated by silent intervals, negative air sac pressure, and inspiratory air flow. In order to study the mus... | Minibreath; Expiration; Inspiration | 1997 |

Henderson, Thomas C. | Instrumented sensor system - practice | In previous work, we introduced the notion of Instrumented Logical Sensor Systems (ILSS) that are derived from a modeling and design methodology [4, 2].
