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.

Malariasphere: A Greenhouse-Enclosed Simulation Of A Natural Anophelesgambiae (Diptera: Culicidae) Ecosystem In Western Kenya, Bart G.J. Knols, Basilio N. Njiru, Evan M. Mathenge, Wolfgang R. Mukabana, John C. Beier, Gerry F. Killeen Dec 2002

Malariasphere: A Greenhouse-Enclosed Simulation Of A Natural Anophelesgambiae (Diptera: Culicidae) Ecosystem In Western Kenya, Bart G.J. Knols, Basilio N. Njiru, Evan M. Mathenge, Wolfgang R. Mukabana, John C. Beier, Gerry F. Killeen

All Peer-Reviewed Publications

Background: The development and implementation of innovative vector control strategies for malaria control in Africa requires in-depth ecological studies in contained semi-field environments. This particularly applies to the development and release of genetically-engineered vectors that are refractory to Plasmodium infection. Here we describe a modified greenhouse, designed to simulate a natural Anopheles gambiae Giles ecosystem, and the first successful trials to complete the life-cycle of this mosquito vector therein. Methods: We constructed a local house, planted crops and created breeding sites to simulate the natural ecosystem of this vector in a screen-walled greenhouse, exposed to ambient climate conditions, in western …

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.

Determining The Impacts Of Storage Practice And Treatment Technology On The Formation Of Disinfection Byproducts, Greta Myerchin Mcgee Dec 2002

Determining The Impacts Of Storage Practice And Treatment Technology On The Formation Of Disinfection Byproducts, Greta Myerchin Mcgee

Theses (Unassigned)

Disinfection byproducts (DBP) are formed during the reaction of chemical disinfectants with natural organic material (NOM). DBPs are potential carcinogens and are regulated by the US Environmental Protection Agency (USEP A) under the Disinfectant/DBP (D/DBP) rule. High concentrations of NOM in drinking water sources used by Alaska's communities often result in the formation of DBPs during treatment. Since surface water sources in the Arctic are frozen for 6-9 months of the year, communities are often forced to store raw water for treatment during the winter or treat and store enough drinking water during the summer to last through the winter. …

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, …

Predicting Contaminant Transport Pathways In The Caribou-Poker Creek Research Watershed, Vincent Autier Dec 2002

Predicting Contaminant Transport Pathways In The Caribou-Poker Creek Research Watershed, Vincent Autier

Theses (Unassigned)

In order to evaluate the impact of natural organic matter (NOM) on drinking water, the hydrology of the Caribou-Poker Creeks Research Watershed (CPCRW) was considered. The CPCRW provided an excellent opportunity to investigate contaminant transport as it relates to hydrology in a well studied, discontinuous permafrost environment. The seasonal variation of organic chemistry of three different water sources (i.e. ground water, artesian spring and stream) was studied during the course of the year 2001. This thesis comprises three chapters, each of which seeks to gain a better understanding of the contaminant transport pathways in a boreal watershed, Caribou Poker Creeks …

Comparison Of Snowshoe Hare Populations In Interior Alaska, Bjorn Flora Dec 2002

Comparison Of Snowshoe Hare Populations In Interior Alaska, Bjorn Flora

Biological Sciences

Snowshoe hares, Lepus americanus, are a 'keystone' prey species in northern boreal forests and experience population fluctuations of 8-11-years. Despite intense responses of both vegetation and predators to changes in hare densities, landscape-scale comparisons of hare populations in Alaska have been limited to qualitative descriptions. We conducted capture-recapture studies of snowshoe hares at 5 locales in the Tanana valley, from Tok in the east to Clear in the west from 1999 to 2002. Snowshoe hare densities were highest in 1999 (x=6.36 ha⁻¹, SE=0.63) and declined thereafter. We were unable to detect declines in apparent survival during declining densities in our …

Patentable Subject [Anti]Matter, Kristoffer Leftwich Dec 2002

Patentable Subject [Anti]Matter, Kristoffer Leftwich

Duke Law & Technology Review

The statements, "The laws of nature," "the principles of nature," "the fundamental truths," etc., are not patentable, have been oft repeated but seldom understandingly used. They have led to misunderstanding and much confusion, not limited to members of the bar. In fact, the words... are all words of broad and also elastic meaning and are frequently used carelessly and without any attempt at refined distinctions.

The Ecology Of Eulachon (Thaleichthys Pacificus) In Twentymile River, Alaska, Elizabeth Ann Spangler Dec 2002

The Ecology Of Eulachon (Thaleichthys Pacificus) In Twentymile River, Alaska, Elizabeth Ann Spangler

Fisheries

The ecology of eulachon (Thaleichthys pacificus) was studied at Twentymile River, a tributory of Turnagain Arm located in southcentral Alaska. In 2000 and 2001, we investigated the environmental factors associated with the migration of adult eulachon and downstream drift of larval eulachon. We assessed run timing, freshwater duration, length, weight, age, presence or absence of teeth, fecundity, and gear selectivity for dip and gill nets. Catch per unit effort of migrating adult fish were correlated with water temperature, tide height, river discharge, light intensity, and the density of bald eagles (Haliaeetus leucocephalus). Water temperature, river discharge, tide height, and light …

The Ecological Genetics Of Gynodioecy In Silene Acaulis L. (Caryophyllaceae): Spatial Sex Structure And Inbreeding Depression, Stephen Robert Keller Dec 2002

The Ecological Genetics Of Gynodioecy In Silene Acaulis L. (Caryophyllaceae): Spatial Sex Structure And Inbreeding Depression, Stephen Robert Keller

Biological Sciences

Gynodioecy, the co-occurrence of females and hermaphrodites, is considered an intermediate step in the evolution of separate sexes in flowering plants. Highly variable female frequencies among populations suggest structuring of sex determining genes and differences in the relative fitness of females and hermaphrodites as seed parents. I investigated spatial variability in sex ratio and the effects of inbreeding on offspring quality in Silene acaulis. Female frequencies varied among populations from 0.32 to 0.69, and most were at temporal equilibrium. Females were significantly clumped within two of six populations. Females produced from 4 to 27 times as many fruits as hermaphrodites. …

Stratigraphy, Major Oxide Geochemistry, And ⁴⁰Ar/³⁹Ar Geochronology Of A Tephra Section Near Tok, Alaska, Janet Schaefer Dec 2002

Stratigraphy, Major Oxide Geochemistry, And ⁴⁰Ar/³⁹Ar Geochronology Of A Tephra Section Near Tok, Alaska, Janet Schaefer

Geosciences

Stratigraphy, major oxide geochemistry, and ⁴⁰Ar/³⁹Ar geochronology are used to describe a tephra section near Tok, Alaska, north ofthe Wrangell volcanic field. This tephra section contains seven type II tephras and two type I tephras. Hornblende in a tephra near the base of the section was dated at 627.5 +/- 47.7 ka using the ⁴⁰Ar/³⁹Ar method of single-step total laser fusion. This hornblende-rich tephra is here named the Tetlin Tephra. The age and composition of the Tetlin Tephra indicates that it is likely the product of an explosive phase of activity of Mount Drum volcano, where petrologically similar domes were …

Development Of High Spectral Resolution Iron Boltzmann Lidar, Tao Hou Dec 2002

Development Of High Spectral Resolution Iron Boltzmann Lidar, Tao Hou

Engineering

An initial iron (Fe) Boltzmann lidar was developed in winter 2000-2001 at Poker Flat Research Range (PFRR). This resonance lidar system supported Fe concentration measurements. An initial Fe Boltzmann temperature measurement was made in December 2000. This initial system was fundamentally limited by the 1 pm tuning resolution of the laser. During the winter of 2001-2002, a control system was developed to increase the resolution of the laser tuning to 0.09 pm. Fe cooncentration and Fe Boltzmann temperature measurements were made and an experimental analysis of the measurements was developed. This thesis presents lidar observations of the mesospheric Fe layer …

Rapid Evaluation Of The Gel Strength Of Gtl Products During A Prolonged Trans-Alaska Pipeline Shutdown, Michael Donovon Timmcke Dec 2002

Rapid Evaluation Of The Gel Strength Of Gtl Products During A Prolonged Trans-Alaska Pipeline Shutdown, Michael Donovon Timmcke

Engineering

A prolonged winter shutdown of the Trans-Alaska Pipeline (TAPS) could cause the fluid in the pipeline to form a gel with sufficient strength to prevent restart. With the economic viability of a North Slope Gas-To-Liquid (GTL) plant improving, understanding the effect the addition of GTL products to TAPS will have on the gel strength of pipeline fluids is essential to quantify the risk of such a project. This study presents the development of a fast cold ramp technique to predict the gel strength of TAPS fluids. The gel strength of various blend ratios of GTL and crude oil are determined …

Ice, Bedload Transport, And Channel Morphology On The Upper Kuparuk River, Jeffrey Albert Oatley Dec 2002

Ice, Bedload Transport, And Channel Morphology On The Upper Kuparuk River, Jeffrey Albert Oatley

Engineering

The objective of this study was to quantify the impact of bottom ice on sedimentation processes at a study site on the Upper Kuparuk River, in Northern Alaska. The approach taken was to use the Meyer-Peter and Mueller (1948) and Parker (1990) equations to determine bedload rating curves at four cross sections within the study reach, and to apply these rating curves to the ten year flow history of the study site to determine the total potential bedload transport that was suppressed during snowmelt runoff. In conjunction with this analysis, a tracer rock study was performed at the study site. …

From March to May 2001, aerosol size distributions and chemical compositions were measured using differential mobility analyzers (DMA), an aerodynamic particle sizer (APS), Micro-Orifice Uniform Deposit Impactors (MOUDI), and denuder samplers onboard the Twin Otter aircraft as part of the Aerosol Characterization Experiment (ACE)-Asia campaign. Of the 19 research flights, measurements on four flights that represented different aerosol characteristics are analyzed in detail. Clear-column radiative closure is studied by comparing aerosol extinctions predicted using in situ aerosol size distribution and chemical composition measurements to those derived from the 14-wavelength NASA Ames Airborne Tracking Sun photometer (AATS-14). In the boundary layer, …
