Rapidity And Centrality Dependence Of Proton And Antiproton Production From 197Au + 197Au Collisions At √SNn=130 Gev, Star Collaboration, T.D. Gutierrez Oct 2004

Rapidity And Centrality Dependence Of Proton And Antiproton Production From 197Au + 197Au Collisions At √SNn=130 Gev, Star Collaboration, T.D. Gutierrez

Physics

We report on the rapidity and centrality dependence of proton and antiproton transverse mass distributions from 197Au+197Au collisions at √sNN=130 GeV as measured by the STAR experiment at the Relativistic Heavy Ion Collider (RHIC). Our results are from the rapidity and transverse momentum range of ∣y∣<0.5 and 0.35 < pt < 1.00 GeV ∕ c. For both protons and antiprotons, transverse mass distributions become more convex from peripheral to central collisions demonstrating characteristics of collective expansion. The measured rapidity distributions and the mean transverse momenta versus rapidity are flat within ∣y∣<0.5. Comparisons of our data with results from model calculations indicate that in order to obtain a consistent picture of the proton (antiproton) yields and transverse mass distributions the possibility of prehadronic collective expansion may have to be taken into account.

Record Hail Event – Examination Of The Aurora, Nebraska Supercell Of 22 June 2003, Jared Guyer, Rick Ewald Oct 2004

Record Hail Event – Examination Of The Aurora, Nebraska Supercell Of 22 June 2003, Jared Guyer, Rick Ewald

United States Department of Commerce: Staff Publications

During the late afternoon and early evening hours of 22 June 2003, thunderstorms developed from central Nebraska into north central Kansas, quickly becoming severe in an environment favorable for supercell thunderstorms. On this evening, portions of central Nebraska and north central Kansas were affected by tornadoes, destructive hail, and severe flooding.
In particular, a supercell thunderstorm moved northeastward across the community of Aurora, Nebraska, producing extremely large hail and multiple short-lived tornadoes. A record setting hailstone was ultimately discovered in Aurora, measuring 7.0 inches (17.78 cm) in diameter with an 18.75 inch (47.63 cm) circumference. This hailstone broke the previous …

Avian Use Of Harvested Crop Fields During Spring Migration Trrough North Dakota, Alegra M. Galle, George M. Linz, William J. Bleier Oct 2004

Avian Use Of Harvested Crop Fields During Spring Migration Trrough North Dakota, Alegra M. Galle, George M. Linz, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

Over the past century, the amount of mixed-grass prairie in North Dakota has diminished with a concomitant increase in land used for crop production. Consequently, the diversity of habitat available for migrant birds has decreased, and birds are now limited to choosing habitats that are uncharacteristic of those used during other times of the year. Because of the extensive agricultural production in this region, the value of harvested crop fields to spring-migrating birds was studied by examining avian habitat use in harvested fields to determine differences in bird use among these habitats. In the spring of 2003, 60 harvested fields …

A Complete Probabilistic Framework For Learning Input Models For Power And Crosstalk Estimation In Vlsi Circuits, Nirmal Munuswamy Ramalingam Oct 2004

A Complete Probabilistic Framework For Learning Input Models For Power And Crosstalk Estimation In Vlsi Circuits, Nirmal Munuswamy Ramalingam

USF Tampa Graduate Theses and Dissertations

Power disspiation is a growing concern in VLSI circuits. In this work we model the data dependence of power dissipation by learning an input model which we use for estimation of both switching activity and crosstalk for every node in the circuit. We use Bayesian networks to effectively model the spatio-temporal dependence in the inputs and we use the probabilistic graphical model to learn the structure of the dependency in the inputs. The learned structure is representative of the input model. Since we learn a causal model, we can use a larger number of independencies which guarantees a minimal structure. …

Centrality And Pseudorapidity Dependence Of Charged Hadron Production At Intermediate PT In Au+Au Collisions At √SNn=130 Gev, Star Collaboration, T.D. Gutierrez Oct 2004

Centrality And Pseudorapidity Dependence Of Charged Hadron Production At Intermediate PT In Au+Au Collisions At √SNn=130 Gev, Star Collaboration, T.D. Gutierrez

Physics

We present STAR measurements of charged hadron production as a function of centrality in Au+Au collisions at √sNN=130 GeV. The measurements cover a phase space region of 0.2T<6.0GeV∕c in transverse momentum and −1<η<1 in pseudorapidity. Inclusive transverse momentum distributions of charged hadrons in the pseudorapidity region 0.5<∣η∣<1 are reported and compared to our previously published results for ∣η∣<0.5. No significant difference is seen for inclusive pT distributions of charged hadrons in these two pseudorapidity bins. We measured dN∕dη distributions and truncated mean pT in a region of pT>pTcut, and studied the results in the framework of participant and binary scaling. No clear evidence is observed for participant scaling of charged hadron yield in the measured pT region. The relative importance of hard scattering processes is investigated through binary …

Dark-Matter Electric And Magnetic Dipole Moments, Kris Sigurdson, Michael Doran, Andriy Kurylov, Robert R. Caldwell, Marc Kamionkowski Oct 2004

Dark-Matter Electric And Magnetic Dipole Moments, Kris Sigurdson, Michael Doran, Andriy Kurylov, Robert R. Caldwell, Marc Kamionkowski

Dartmouth Scholarship

We consider the consequences of a neutral dark-matter particle with a nonzero electric and/or magnetic dipole moment. Theoretical constraints, as well as constraints from direct searches, precision tests of the standard-model, the cosmic microwave background and matter power spectra, and cosmic gamma rays, are included. We find that a relatively light particle with mass between an MeV and a few GeV and an electric or magnetic dipole as large as ∼3×10−16e  cm (roughly 1.6×10−5μB) satisfies all experimental and observational bounds. Some of the remaining parameter space may be probed with forthcoming more sensitive direct searches and with the Gamma-Ray Large …

Effects Of Aerial Lines On Red-Winged Blackbird Nesting Success, William H. Clark, George M. Linz, William J. Bleier Oct 2004

Effects Of Aerial Lines On Red-Winged Blackbird Nesting Success, William H. Clark, George M. Linz, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

Crop damage attributed to foraging red-winged blackbirds continues to be a problem in localized areas of the United States. Therefore, new methods that are both environmentally and public friendly need to be developed for repelling blackbirds. One such method that is more humane and less hazardous than the chemical control is the use of aerial lines to repel birds. The purpose of this study was to evaluate the effect of aerial lines on the reproductive effort of nesting red-winged blackbirds and to determine the spacing, type, and size of aerial lines that are most effective. Maximum likelihood estimates for the …

Quantification Of Cattail (Typha Spp.) In The Prairie Pothole Region Of North Dakota In Relation To Blackbird Damage To Sunflower, Scott T. Ralston, George M. Linz, William J. Bleier Oct 2004

Quantification Of Cattail (Typha Spp.) In The Prairie Pothole Region Of North Dakota In Relation To Blackbird Damage To Sunflower, Scott T. Ralston, George M. Linz, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

Sunflower is an important crop for many farmers in the upper Midwest, especially in North Dakota and South Dakota. Blackbirds have been a major problem for the sunflower grower community. Bud depredation to a field can be devastating. The USDA-APHISWS is charged with reducing the conflict between the birds and the farmers. Many methods have been employed by Wildlife Services and other agencies to lessen the damage. One method is the reduction of the cattail (Typha spp.) habitat used by blackbirds in and around wetlands; however, cattails are used by other animals. Consequently, there is a need to insure …

Management Of Cattail (Typha Spp.) Stands With Glyphosate To Disperse Blackbirds, George M. Linz, H. Jeffrey Homan, Ryan L. Wimberly, Philip Mastrangelo, William J. Bleier Oct 2004

Management Of Cattail (Typha Spp.) Stands With Glyphosate To Disperse Blackbirds, George M. Linz, H. Jeffrey Homan, Ryan L. Wimberly, Philip Mastrangelo, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

In the Prairie Pothole Region of North Dakota and South Dakota, blackbirds (Icteridae) gather by the thousands in large premigratory roosts in late summer and early fall. Wetlands dominated by cattails (Typha spp.) provide ideal roosting habitat for these aggregations. Sunflower fields near large roosts can receive substantial damage. To eliminate potential roosting sites, Wildlife Services of the United States Department of Agriculture has implemented a cattail management program that aerially sprays dense cattail stands with the herbicide glyphosate m-(phosphonomethyl) glycine]. The continued viability of the program depends on a positive benefit-cost ratio and minimal environmental impacts. In this …

Avian Use Of Roadside Habitat In The Southern Drift Plains Of North Dakota And Implications For Cattail (Typha Spp.) Management, Bryan D. Safratowich, George M. Linz, William J. Bleier Oct 2004

Avian Use Of Roadside Habitat In The Southern Drift Plains Of North Dakota And Implications For Cattail (Typha Spp.) Management, Bryan D. Safratowich, George M. Linz, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

We determined avian use of roadside rights-of-way to develop proper management strategies for the manipulation of roadside cattail. Cattail management is a technique used to reduce nesting and roosting habitat for problematic blackbird species, which might feed on sunflower crops in the vicinity of cattail-dominated wetlands. Thirty quarter sections (1 quarter section ≈ 64.75 ha) located in the Southern Drift Plains of North Dakota served as our study units. Roadside habitat along two 0.5 mile (-0.8 km) transects bordering these quarter sections was surveyed to assess avian use. Additionally, nest surveys were , conducted to provide an index of breeding …

Influences Of Land Use Patterns On Blackbird Abundance In The Prairie Pothole Region Of North Dakota, Greg M. Forcey, George M. Linz, William J. Bleier Oct 2004

Influences Of Land Use Patterns On Blackbird Abundance In The Prairie Pothole Region Of North Dakota, Greg M. Forcey, George M. Linz, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

One issue affecting sunflower growers in the upper Great Plains of North America is crop depredation by blackbirds. In this region, blackbirds annually destroy an average of $5.4 million of sunflower. To increase the understanding of how blackbirds are influenced by large-scale land-use patterns, we developed multiple regression models to explain how various land use patterns influence blackbird abundance. We used data from the North American Breeding Bird Survey and the USGS land cover assessment to develop regression models examining associations between land use characteristics and blackbird abundance. Both red-winged blackbirds and yellow-headed blackbirds were negatively associated with the amount …

Skeletal Muscle Fiber Atrophy: Altered Thin Filament Density Changes Slow Fiber Force And Shortening Velocity, Danny A. Riley, J. L. W. Bain, Janell Romatowski, Robert H. Fitts

Biological Sciences Faculty Research and Publications

Single skinned fibers from soleus and adductor longus (AL) muscles of weight-bearing control rats and rats after 14-day hindlimb suspension unloading (HSU) were studied physiologically and ultrastructurally to investigate how slow fibers increase shortening velocity (V0) without fast myosin. We hypothesized that unloading and shortening of soleus during HSU reduces densities of thin filaments, generating wider myofilament separations that increase V0 and decrease specific tension (kN/m2). During HSU, plantarflexion shortened soleus working length 23%. AL length was unchanged. Both muscles atrophied as shown by reductions in fiber cross-sectional area. For AL, the 60% atrophy …

El Nino Southern Oscillation-Related Salinity Variations Recorded In The Skeletal Geochemistry Of A Porites Coral From Espiritu Santo, Vanuatu, K. H. Kilbourne, Terrence M. Quinn, Frederick W. Taylor, Thierry Delcroix, Yves Gouriou Oct 2004

El Nino Southern Oscillation-Related Salinity Variations Recorded In The Skeletal Geochemistry Of A Porites Coral From Espiritu Santo, Vanuatu, K. H. Kilbourne, Terrence M. Quinn, Frederick W. Taylor, Thierry Delcroix, Yves Gouriou

Marine Science Faculty Publications

Coral skeletal geochemistry offers the potential to reconstruct the sea surface salinity (SSS) history of the tropical oceans on seasonal to interannual and perhaps centennial timescales because of the strong link between variation in SSS and seawater δ18O in tropical regions. We explore this potential using a monthly resolved, 65‐year record of skeletal δ18O and Sr/Ca variations in a Porites coral from Espiritu Santo, Vanuatu. We demonstrate that El Niño–Southern Oscillation–related climate variability strongly influences coral δ18O at Santo through local salinity changes associated with the position of the South Pacific Convergence Zone and …

Performance Evaluation Of A Resource Discovery Service, Jue Wang Oct 2004

Performance Evaluation Of A Resource Discovery Service, Jue Wang

Dartmouth College Master’s Theses

In a pervasive computing environment, the number and variety of resources (services, devices, and contextual information resources) make it necessary for applications to accurately discover the best ones quickly. Thus a resource-discovery service, which locates specific resources and establishes network connections as better resources become available, is necessary for those applications. The performance of the resource-discovery service is important when the applications are in a dynamic and mobile environment. In this thesis, however, we do not focus on the resource- discovery technology itself, but the evaluation of the scalability and mobility of the resource discovery module in Solar, a context …

Towards Predictable Service Provision In Mobile Ad Hoc Networks, Rohan Sen, Gregory Hackmann, Gruia-Catalin Roman, Christopher Gill Oct 2004

Towards Predictable Service Provision In Mobile Ad Hoc Networks, Rohan Sen, Gregory Hackmann, Gruia-Catalin Roman, Christopher Gill

All Computer Science and Engineering Research

This paper considers the technical challenges associated with the development of applications designed to work over mobile ad hoc net-works (MANETs). The setting is one in which a miniature application core residing on a mobile host with limited resources is able to support a complex application in a changing open environment by exploiting ser-vices made available by other hosts it encounters. The proposed solution extends in a novel way the applicability of the service provision paradigm to the ad hoc wireless setting. The novelty of the approach rests with the accumulation and management of knowledge about the service structure and …

Hohenberg-Kohn Theory Including Spin Magnetism And Magnetic Fields, Walter Kohn, Andreas Savin, Carsten A. Ullrich Oct 2004

Hohenberg-Kohn Theory Including Spin Magnetism And Magnetic Fields, Walter Kohn, Andreas Savin, Carsten A. Ullrich

Physics Faculty Research & Creative Works

Beginning with work by U. von Earth and L. Hedin in 1972 and continuing with recent papers in 2001 by K. Capelle and G. Vignale and by H. Eschrig and W. E. Pickett, questions have been raised about the meaning and validity of Hohenberg-Kohn theory when spin magnetism and/or magnetic fields are present. This article offers clarifications of some of these questions. in particular, it also concludes that these questions do not affect spin-density functional theory for nondegenerate ground states as currently practiced. © 2004 Wiley Periodicals, Inc.
