Accent and Grouping Structures in the String Quartets of Béla Bartók
The music of Béla Bartók is defined in part by its unique blend of rhythmic vitality and inventiveness, and his string quartets offer a glimpse into a consistency of technique evident throughout his compositional career. Bartók's rhythmic environments are primarily metrical, but many of his rhythmic configurations are placed in such a way as to potentially override established meter. It is necessary, therefore, to institute an analytical means by which the delineation and comparison of rhythmic structures both within and without the metrical context may be accomplished. An analytical method using Timepoint Accent Structures (TAS) allows for the comparison of rhythms resulting from patterns of accent produced by pitch onset, dynamic stress, articulation or any other accentual factors. Timepoint Grouping Structures (TGS) delineate the number of timepoints present in alternating groups/blocks in a texture, thereby allowing for the recognition of patterning created by these larger groups. By applying TAS and TGS analysis, relationships of rhythmic equivalency, rotation, retrograde, complementation, augmentation, diminution, subset, superset, exchange, compression and expansion are clearly confirmed in the string quartets. In addition, symmetrical structures and arithmetic progressions are discovered. In many ways, Bartók's rhythmic organization mimics his procedures of pitch structuring.

Activating Space within the Object and the Site
I look at the world as a sculptor, examining physical constructs and implied meanings. My current research developed from my earlier studies of “containment” or, more specifically, “encapsulation,” creating visual, often physical, boundaries around selected content. Encapsulation confers a more active role than “containment”, a process rather than a result. This idea speaks to the issues of form, and asks the viewer to question the outside “shape of the form” in relation to the inside shape and content. My work focuses on exposed interior spaces and forms, allowing the viewer to enter the space physically as well as mentally and psychologically. Built in a large enough scale, the viewer could actually become the content. The sculpture’s interpretation revolves around the seen as well as the unseen. I built this duality into my work by using transparent and opaque materials. I also implemented small diameter stainless steel rod along with the transparent and opaque vinyl to reduce forms to their respective shapes and volumes. This approach allowed me to clean the “slate” of an object’s collective meaning and context, adapting it to the intent of my work.

Adult Chinook Salmon Abundance Monitoring in the Secesh River and Lake Creek, Idaho, 2000 Annual Report.
Underwater time-lapse video technology has been used to monitor adult spring and summer chinook salmon (Oncorhynchus tshawytscha) escapement into the Secesh River and Lake Creek, Idaho, since 1998. Underwater time-lapse videography is a passive methodology that does not trap or handle this Endangered Species Act listed species. Secesh River chinook salmon represent a wild spawning aggregate that has not been directly supplemented with hatchery fish. The Secesh River is also a control population under the Idaho Salmon Supplementation study. This project has demonstrated the successful application of underwater video adult salmon abundance monitoring technology in Lake Creek in 1998 and 1999. Emphasis of the project in 2000 was to determine if the temporary fish counting station could be installed early enough to successfully estimate adult spring and summer chinook salmon abundance in the Secesh River (a larger stream). Snow pack in the drainage was 93% of the average during the winter of 1999/2000, providing an opportunity to test the temporary count station structure. The temporary fish counting station was not the appropriate technology to determine adult salmon spawner abundance in the Secesh River. Due to its temporary nature it could not be installed early enough, due to high stream discharge, …

ADVANCED FLUE GAS CONDITIONING AS A RETROFIT UPGRADE TO ENHANCE PM COLLECTION FROM COAL-FIRED ELECTRIC UTILITY BOILERS
The U.S. Department of Energy and ADA Environmental Solutions has begun a project to develop commercial flue gas conditioning additives. The objective is to develop conditioning agents that can help improve particulate control performance of smaller or under-sized electrostatic precipitators on utility coal-fired boilers. The new chemicals will be used to control both the electrical resistivity and the adhesion or cohesivity of the flyash. There is a need to provide cost-effective and safer alternatives to traditional flue gas conditioning with SO{sub 3} and ammonia. During the fourth reporting quarter, laboratory-screening tests of more than 20 potential additive formulations were completed. For these tests, the electrostatic tensiometer method was used for determination of flyash cohesivity. Resistivity was measured for each screening test with a new multi-cell laboratory flyash resistivity furnace constructed for this project. An initial field trial of three additive formulations was also conducted at the City of Ames, Iowa Municipal Power Plant.

Age-Dependent Effects Of Chronic GABAA Receptor Blockade In Barrel Cortex
GABAA receptor binding is transiently increased in rat whisker barrels during the second postnatal week, at a time when neurons in the developing rat cortex are vulnerable to excitotoxic effects. To test whether these GABAA receptors might serve to protect neurons from excessive excitatory input, polymer implants containing the GABAA receptor antagonist bicuculline were placed over barrel cortex for a 4-day period in young (postnatal days 8 - 12) and adult rats. In the cortex of young, but not adult rats, the chronic blockade of GABAA receptors resulted in substantial tissue loss and neuron loss. The greater loss of neurons in young rats supports the hypothesis that a high density of GABAA receptors protects neurons from excessive excitatory input during a sensitive period in development.

American Choral Music in Late 19th Century New Haven: The Gounod and New Haven Oratorio Societies
This study examines two of the smaller American choral societies that together existed for just over 30 years, 1888 to 1919: The Gounod and New Haven Oratorio Societies of New Haven, Connecticut. These societies are important because, especially in the case of the New Haven Society, they were closely related to Yale University and the work of Horatio Parker. One must assume from the onset that the two choral groups examined in the following pages did not have the prominence of the many larger New England choral societies. However a more detailed knowledge about the struggles, successes, influence and leadership of two smaller societies illuminates a field of research in the history of American choral music that has been largely ignored.

ANALOG QUANTUM NEURON FOR FUNCTIONS APPROXIMATION
We describe a system able to perform universal stochastic approximations of continuous multivariable functions in both neuron-like and quantum manner. The implementation of this model in the form of multi-barrier multiple-silt system has been earlier proposed. For the simplified waveguide variant of this model it is proved, that the system can approximate any continuous function of many variables. This theorem is also applied to the 2-input quantum neural model analogical to the schemes developed for quantum control.

ANALYSIS OF DATA FROM THE LEDA WIRE SCANNER/HALO SCRAPER
A new diagnostic has been designed and commissioned that measures the profile of the beam in the halo channel of the Low Energy Demonstration Accelerator at the Los Alamos National Laboratory. This paper describes the algorithms written to analyze the data from that diagnostic, a combined wire scanner and halo scraper. These algorithms determine the safe insertions limit of the scrapers, spatially differentiate the scraper signal, amalgamate the wire scanner data with the differentiated scraper data, determine when both the core and combined distributions rise above the noise floor, and compute the moments of the combined distribution. Results of applying the algorithms to data acquired during experiments matching the beam into the halo channel are presented.

Analysis of Depth-Sensing Indentation Tests with a Knoop Indenter
The present work shows how data obtained in a depth-sensing indentation test using a Knoop indenter may be analyzed to provide elastic modulus and hardness of the specimen material. The method takes into account the elastic recovery along the direction of the short axis of the residual impression as the indenter is removed. If elastic recovery is not accounted for, the elastic modulus and hardness are overestimated by an amount that depends on the ratio of E/H of the specimen material. The new method of analysis expresses the elastic recovery of the short diagonal of the residual impression into an equivalent face angle for one side of the Knoop indenter. Conventional methods of analysis using this corrected angle provide results for modulus and hardness that are consistent with those obtained with other types of indenters.

An Analysis of Teaching Periodicals for Aging Education Content
Ninety elementary public school teachers were surveyed to find out where they obtained their teaching ideas. Seven popular elementary-level teaching periodicals, dated 1989-1999, were analyzed for aging-related content, and compared with 27 of the National Academy for Teaching and Learning about Aging (NATLA) aspects of aging recommended for students' learning. Results indicate that public elementary teachers obtain their teaching ideas from various places: teaching institutes or workshops; other teachers; ideas or lessons they develop themselves; and teaching periodicals. A large percentage obtain lesson ideas from teaching periodicals that they browse or read. This finding may assist NATLA in making recommendations to particular editorial boards. Surprisingly, few teachers obtain their teaching ideas from state and local curricular mandates. When the periodical issues were analyzed, aging-related content was categorized in four ways: informational articles with selected teaching or learning activities; articles describing intergenerational programs or activities; book reviews with selected learning activities; and book review titles mentioning older adult characters. Category totals among the 7 periodicals were highest in book review titles mentioning older adult characters and book reviews with selected learning activities. The content was compared to NATLA's recommendations for students' learning. The findings were not significant. The aging aspect that …

Antinucleus productions at RHIC
Light antinuclei may be formed in relativistic heavy ion collisions via final state coalescence of antinucleons. The yields of antinuclei are sensitive to primordial antinucleon production, the volume of the system at kinetic freeze-out, and space-momentum correlations among antinucleons at freeze-out. We report here preliminary STAR results on {bar d} and {bar {sup 3}He} production in 130A GeV Au+Au collisions. These results are examined in a coalescence framework to elucidate the space-time structure of the antinucleon source.

Are Topological Charge Fluctuations in QCD Instanton Dominated?
We consider a recent proposal by Horvath et al. to address the question whether topological charge fluctuations in QCD are instanton dominated via the response of fermions using lattice fermions with exact chiral symmetry, the overlap fermions. Considering several volumes and lattice spacings we find strong evidence for chirality of a finite density of low-lying eigenvectors of the overlap-Dirac operator in the regions where these modes are peaked. This result suggests instanton dominance of topological charge fluctuations in quenched QCD.

Assessment and Comparison of the Stress Experienced by International and American Students at the University of North Texas
There were two purposes of the current study: (1) to evaluate if the East Asian Student Stress Inventory could be used to assess the stress experienced by International and American students at the University of North Texas and (2) to determine if the Inventory could discriminate between the two groups on the basis of the stress assessment. A sample of International (n=205) and American (n=216) graduate and undergraduate students completed the inventory. Results indicated that the EASSI could be generalized to a wider spectrum of International students. Using principal component factor analysis with varimax rotation, eight factors were extracted: culture shock, physiological symptoms, family pressure, test anxiety, financial difficulties, attitude toward study, social support and academic self esteem. The inventory clearly discriminated between the two groups on the subscales of culture shock, family pressure and attitude toward study and the International students scored higher on these subscales.

An Assessment of the Current Day Impact of Various Materials Associated with the U.S. Nuclear Test Program in the Marshall Island
Different stable elements, and some natural and man-made radionuclides, were used as tracers or associated in other ways with nuclear devices that were detonated at Bikini and Enewetak Atolls as part of the U.S. nuclear testing program from 1946 through 1958. The question has been raised whether any of these materials dispersed by the explosions could be of sufficient concentration in either the marine environment or on the coral islands to be of a health concern to people living, or planning to live, on the atolls. This report addresses that concern. An inventory of the materials involved during the test period was prepared and provided to us by the Office of Defense Programs (DP) of the United States Department of Energy (DOE). The materials that the DOE and the Republic of the Marshall Islands (RMI) ask to be evaluated are--sulfur, arsenic, yttrium, tantalum, gold, rhodium, indium, tungsten, thallium, thorium-230,232 ({sup 230,232}Th), uranium-233,238 ({sup 233,238}U), polonium-210 ({sup 210}Po), curium-232 ({sup 232}Cu), and americium-241 ({sup 241}Am). The stable elements were used primarily as tracers for determining neutron energy and flux, and for other diagnostic purposes in the larger yield, multistage devices. It is reasonable to assume that these materials would be distributed …
