Identifying The Burdens And Opportunities For Tribes And Communities In Federal Facility Cleanup Activities: Environmental Remediation Technology Assessment Matrix For Tribal And Community Decision-Makers, International Institute For Indigenous Resource Management, Inc. (Iiirm), Mervyn L. Tano, Jeanne M. Rubin, Kacey C. Denham

International Institute for Indigenous Resource Management, Inc. (IIIRM)

The cleanup of this country’s federal facilities can affect a wide range of tribal and community interests and concerns. The technologies now in use, or being proposed by the Department of Energy, Department of Defense and other federal agencies can affect tribal treaty protected fishing, hunting and other rights, affect air and water quality thereby requiring the tribe to bear the burden of increased environmental regulation. The International Institute for Indigenous Resource Management developed a tribal and community decision-maker’s Environmental Remediation Technology Assessment Matrix that will permit tribes and communities to array technical information about environmental remediation technologies against a …

Valley Floor Climate Observations From The Mcmurdo Dry Valleys, Antarctica, 1986-2000, Peter T. Doran, Christopher P. Mckay, Gary D. Clow, Gayle L. Dana, Andrew G. Fountain, Thomas H. Nylen, W. Berry Lyons Dec 2002

Valley Floor Climate Observations From The Mcmurdo Dry Valleys, Antarctica, 1986-2000, Peter T. Doran, Christopher P. Mckay, Gary D. Clow, Gayle L. Dana, Andrew G. Fountain, Thomas H. Nylen, W. Berry Lyons

Geography Faculty Publications and Presentations

Climate observations from the McMurdo dry valleys, East Antarctica are presented from a network of seven valley floor automatic meteorological stations during the period 1986 to 2000. Mean annual temperatures ranged from −14.8°C to −30.0°C, depending on the site and period of measurement. Mean annual relative humidity is generally highest near the coast. Mean annual wind speed increases with proximity to the polar plateau. Site to site variation in mean annual solar flux and PAR is due to exposure of each station and changes over time are likely related to changes in cloudiness. During the non-summer months, strong katabatic winds …

A Planet At 5 Au Around 55 Cancri, Geoffrey W. Marcy, R. Paul Butler, Debra A. Fischer, Greg Laughlin, Steve S. Vogt, Gregory W. Henry, Dimitri Pourbaix Dec 2002

A Planet At 5 Au Around 55 Cancri, Geoffrey W. Marcy, R. Paul Butler, Debra A. Fischer, Greg Laughlin, Steve S. Vogt, Gregory W. Henry, Dimitri Pourbaix

Information Systems and Engineering Management Research Publications

We report precise Doppler-shift measurements of 55 Cancri (G8 V) obtained from 1989 to 2002 at Lick Observatory. The velocities reveal evidence for an outer planetary companion to 55 Cancri orbiting at 5.5 AU. The velocities also confirm a second, inner planet at 0.11 AU. The outer planet is the first extrasolar planet found that orbits near or beyond the orbit of Jupiter. It was drawn from a sample of ~50 stars observed with sufficient duration and quality to detect a giant planet at 5 AU, implying that such planets are not rare. The properties of this Jupiter analog may …

Chaotic Free-Space Laser Communication Over Turbulent Channel, N. F. Rulkov, Mikhail Vorontsov, L. Illing Dec 2002

Chaotic Free-Space Laser Communication Over Turbulent Channel, N. F. Rulkov, Mikhail Vorontsov, L. Illing

Electro-Optics and Photonics Faculty Publications

The dynamics of errors caused by atmospheric turbulence in a self-synchronizing chaos-based communication system that stably transmits information over a ∼5  km free-space laser link is studied experimentally. Binary information is transmitted using a chaotic sequence of short-term pulses as a carrier. The information signal slightly shifts the chaotic time position of each pulse depending on the information bit. We report the results of an experimental analysis of the atmospheric turbulence in the channel and the impact of turbulence on the bit-error-rate performance of this chaos-based communication system.

He Ii Reverberation In Active Galactic Nucleus Spectra, Mark C. Bottorff, Jack A. Baldwin, Gary J. Ferland, Jason W. Ferguson, Kirk T. Korista Dec 2002

He Ii Reverberation In Active Galactic Nucleus Spectra, Mark C. Bottorff, Jack A. Baldwin, Gary J. Ferland, Jason W. Ferguson, Kirk T. Korista

Physics and Astronomy Faculty Publications

This paper compares the observed reverberation response lags and the intensity ratios of the broad-line region (BLR) emission lines He II λ1640, He II λ4686, and C IV λ1549 with predictions. Published observations indicate that the He II λ1640 lag is 3 times shorter than the lags of He II λ4686 or C IV λ1549. Diverse models, however, do not reproduce this observation. Extensive improved numerical simulations of the hydrogenic isoelectronic sequence emission show that the He II spectrum remains especially simple, even in the central regions of a luminous quasar. Line trapping never builds up a significant population of …

Characteristics Of Quasi-Monochromatic Gravity Waves Observed With Na Lidar In The Mesopause Region At Starfire Optical Range, Nm, Xiong Hu, Alan Z. Liu, Chester S. Gardner, Gary R. Swenson Dec 2002

Characteristics Of Quasi-Monochromatic Gravity Waves Observed With Na Lidar In The Mesopause Region At Starfire Optical Range, Nm, Xiong Hu, Alan Z. Liu, Chester S. Gardner, Gary R. Swenson

Physical Sciences - Daytona Beach

The University of Illinois Na wind/temperature lidar data collected at the Starfire Optical Range, NM, between Jan. 1998 and May 2000 was used to extract the dominant monochromatic gravity waves. By using simultaneously measured horizontal wind and temperature profiles, the vertical wavelengths (λz), (TI), and propagation directions were determined using the hodograph method. A total of 700 monochromatic gravity waves were analyzed from ~300 h of observations. It was found that 84.4% of the waves were propagating upwards. The mean λz was 12.6 km and 9.9 km for upward and downward propagating waves, respectively, and …

On The Effect Of Random Errors In Gridded Bathymetric Compilations, Martin Jakobsson, Brian R. Calder, Larry A. Mayer Dec 2002

On The Effect Of Random Errors In Gridded Bathymetric Compilations, Martin Jakobsson, Brian R. Calder, Larry A. Mayer

Center for Coastal and Ocean Mapping

We address the problem of compiling bathymetric data sets with heterogeneous coverage and a range of data measurement accuracies. To generate a regularly spaced grid, we are obliged to interpolate sparse data; our objective here is to augment this product with an estimate of confidence in the interpolated bathymetry based on our knowledge of the component of random error in the bathymetric source data. Using a direct simulation Monte Carlo method, we utilize data from the International Bathymetric Chart of the Arctic Ocean database to develop a suitable methodology for assessment of the standard deviations of depths in the interpolated …

Two-Photon Bremsstrahlung Processes In Atoms: Polarization Effects And Analytic Results For The Coulomb Potential, A. A. Krylovetskiĭ, N. L. Manakov, S. I. Marmo, Anthony F. Starace Dec 2002

Two-Photon Bremsstrahlung Processes In Atoms: Polarization Effects And Analytic Results For The Coulomb Potential, A. A. Krylovetskiĭ, N. L. Manakov, S. I. Marmo, Anthony F. Starace

Anthony F. Starace Publications

The partial wave analysis of two-photon free–free (bremsstrahlung) electron transition cross sections during scattering by a static potential U(r), as well as by an atom with a nonzero angular momentum, is carried out. The dipole interaction with radiation is taken into account in the second order of perturbation theory for the general case of elliptic polarization of photons. The polarization and angular dependences of the twophoton potential scattering amplitude is presented as a combination of the scalar product of electron momenta and photon polarization vectors and five atomic parameters containing Legendre polynomials of the scattering angle as …

Search For Minimal Supergravity In Single-Electron Events With Jets And Large Missing Transverse Energy In Pp̅ Collisions At √S =1.8 Tev, V. M. Abazov, Gregory R. Snow, D0 Collaboration Dec 2002

Search For Minimal Supergravity In Single-Electron Events With Jets And Large Missing Transverse Energy In Pp̅ Collisions At √S =1.8 Tev, V. M. Abazov, Gregory R. Snow, D0 Collaboration

Gregory Snow Publications

We describe a search for evidence of minimal supergravity (MSUGRA) in 92.7 pb-1 of data collected with the DØ detector at the Fermilab Tevatron pp̅ collider at√s =1.8 TeV. Events with a single electron, four or more jets, and large missing transverse energy were used in this search. The major backgrounds are from W +jets, misidentified multijet, tt̅, and WW production. We observe no excess above the expected number of background events in our data. A new limit in terms of MSUGRA model parameters is obtained.

A Fast Connection-Time Redirection Mechanism For Internet Application Scalability, Michael Haungs, Raju Pandey, Earl Barr, J. Fritz Barnes Dec 2002

A Fast Connection-Time Redirection Mechanism For Internet Application Scalability, Michael Haungs, Raju Pandey, Earl Barr, J. Fritz Barnes

Computer Science and Software Engineering

Applications that are distributed, fault tolerant, or perform dynamic load balancing rely on redirection techniques, such as network address translation (NAT), DNS request routing, or middleware to handle Internet scale loads. In this paper, we describe a new connection redirection mechanism that allows applications to change end-points of communication channels. The mechanism supports redirections across LANs and WANs and is application-independent. Further, it does not introduce any central bottlenecks. We have implemented the redirection mechanism using a novel end-point control session layer. The performance results show that the overhead of the mechanism is minimal. Further, Internet applications built using this …

Level Oriented Formal Model For Asynchronous Circuit Verification And Its Efficient Analysis Method, Eric G. Mercer, Tomoya Kitai, Chris Myers, Yusuke Oguro, Tomohiro Yoneda Dec 2002

Level Oriented Formal Model For Asynchronous Circuit Verification And Its Efficient Analysis Method, Eric G. Mercer, Tomoya Kitai, Chris Myers, Yusuke Oguro, Tomohiro Yoneda

Faculty Publications

Using a level-oriented model for verification of asynchronous circuits helps users to easily construct formal models with high readability or to naturally model datapath circuits. On the other hand, in order to use such a model on large circuits, techniques to avoid the state explosion problem must be developed. This paper first introduces a level-oriented formal model based on time Petri nets, and then proposes its partial order reduction algorithm that prunes unnecessary state generation while guaranteeing the correctness of the verification.

Excitation Of The Ionized Nitrogen Molecule In The Aurora, Kim Nielsen Dec 2002

Excitation Of The Ionized Nitrogen Molecule In The Aurora, Kim Nielsen

Physics

An understanding of the excitation mechanism of the ionospheric molecules during auroral activity is of vital importance for the overall ionospheric understanding including its interaction with the magnetosphere. In this thesis we study two emissions originating from the excited nitrogen molecule ion. The first negative (0,1) emission at 4278 Å originating from the B state, and Meinel (2,0) emission at 7852 Å originating from the A state during moderate to strong aurora have been observed with an imaging spectrograph at Poker Flat, Alaska. The B state has a short lifetime compared to the inverse collision frequency at auroral altitudes, while …

The Trace Formulas For A Half-Line Schrodinger Operator With Long-Range Potentials, Sergei M. Belov Dec 2002

The Trace Formulas For A Half-Line Schrodinger Operator With Long-Range Potentials, Sergei M. Belov

Theses (Unassigned)

The present work deals with trace formulas for a half-line Schrödinger operator with long-range potentials. These formulas relate the potential with some scattering data. We generalize some relevant results by Buslaev; Faddeev; Gesztesy, Holden, Simon, and others to the case of square integrable potentials. The relation between the number of the trace formulas and the number of integrable derivatives of the potential is also given.

Proinflammatory Cytokines Induce A Rac1-Mediated Superoxide-Dependent Reorganization Of The Actin Cytoskeleton In Neuronal Cells, Shelli Stewart Smeets Dec 2002

Proinflammatory Cytokines Induce A Rac1-Mediated Superoxide-Dependent Reorganization Of The Actin Cytoskeleton In Neuronal Cells, Shelli Stewart Smeets

Chemistry and Biochemistry

A dynamic actin cytoskeleton in central nervous system (CNS) neurons is pivotal for regeneration. Following acute CNS trauma, the proinflammatory cytokines TNF[alpha] and IL-1[beta] become expressed in cells and induce Rac 1-mediated actin filament reorganization. Also, Rac 1 regulates a NAD(P)H oxidase activity that generates superoxide (·O₂). This study's objective was to determine whether TNF[alpha] and/or IL-1[beta] induce a Rac 1-dependent actin filament reorganization in SH-SY5Y neuroblastoma cells and in chick spinal cord neurons via the signaling intermediate, superoxide. SH-SY5Y cells respond to soluble TNF[alpha] or IL-1[beta] with transient, biphasic actin filament reorganization. Over a time period of 30 min, …

Winter Foraging Ecology Of Moose In The Tanana Flats And Alaska Range Foothills, C. Tom Seaton Dec 2002

Winter Foraging Ecology Of Moose In The Tanana Flats And Alaska Range Foothills, C. Tom Seaton

Biological Sciences

I studied woody browse distribution, production, removal, species composition, twig size, moose diets, and predicted daily intake of resident and migratory moose in the Tanana Flats and adjacent Alaska Range Foothills, Alaska, 1999-2000. Density of moose in these areas was high (1.1 moose/km²). Moose were experiencing density-dependent effects on reproduction and growth, exhibited by low adult twinning rate (6%) and absence of pregnant yearlings, yet 17.5 kg higher 10-month-old calf body weights in the migratory segment. Of all willow, poplar, and paper birch plants sampled, 74% had a broomed architecture, which I attributed to heavy use by moose. Using a …

Communication Apprehension: A Narrative Analysis Of The Prca-24, Karri C. Vandeventer Dec 2002

Communication Apprehension: A Narrative Analysis Of The Prca-24, Karri C. Vandeventer

Communication

This exploratory study examined individuals' lived experience with communication apprehension (CA). CA has been explored extensively over the past 35 years by researchers seeking psychological explanations for communication phenomenon and employing the premise that CA exists as a "trait-like" characteristic of personality or as a relatively permanent behavioral disposition. Grounded in a constructionist epistemology, this study presumes that meaning is created, maintained, and transformed through communication with others. From this perspective, CA is an individual's evaluation of anticipated or occurring communication events, based upon his/her prior experiences interacting with others in specific situations. Though CA researchers acknowledge this situational basis …
