A Parallel-Processing Subsystem For Rapid 3-D Interpolation Of Ct Images, William A. Barrett, Stephen J. Allan, Scott R. Cannon

Faculty Publications

An inexpensive parallel-processing subsystem for the rapid interpolation of CT image planes is demonstrated with a variety of node topologies. The subsystem is based on a tree network of INMOS T414 Transputer processors and is hosted by an AT-based image workstation. The subsystem accepts a stack of eight arbitrarily-spaced 256 x 256 image planes from the host. Subsystem output to the host consists of a stack of 32 scaled and evenly-spaced image planes (256 x 256 x 32 with cubic voxels). Benchmark execution times ranged from 12.3 seconds for three nodes to 5.8 seconds for eight nodes.

Inequalities For Sums Of Independent Random Variables, N L. Carothers, S J. Dilworth

Faculty Publications

A moment inequality is proved for sums of independent random variables in the Lorentz spaces LPtq, thus extending an inequality of Rosenthal. The latter result is used in combination with a square function inequality to give a proof of a Banach space isomorphism theorem. Further moment inequalities are also proved.

Quantum Oscillator In A Blackbody Radiation Field Ii. Direct Calculation Of The Energy Using The Fluctuation-Dissipation Theorem, G. W. Ford, J. T. Lewis, R. F. O'Connell

Faculty Publications

An earlier exact result (Phys. Rev. Lett. 55 (1985), 2273) for the free energy of an oscillatordipole interacting with the radiation field is obtained using the fluctuation-dissipation theorem. A key feature of the earlier calculation, a remarkable formula for the free energy of the oscillator, is obtained in the form of a corresponding formula for the oscillator energy. This confirms, by a longer, more conventional proof, the earlier result. An advantage of this present method is that separate contributions to the energy can be isolated and discussed. Explicit, closed-form expressions are given and the high-temperature limit is discussed. © 1988.

Analysis Of The Convergence History Of Fluid Flow Through Nozzles With Shocks, Mohammad Saleem, A Cheer, M Hafez, T Pulliam

Faculty Publications

"Convergence of iterative methods for the solution of the steady quasi-one-dimensional nozzle problem with shocks is considered. The finite-difference algorithms obtained from implicit schemes are used to approximate both the Euler and Navier-Stokes Equations. These algorithms are investigated for stability and convergence characteristics. The numerical methods are broken down into their matrix-vector components and then analyzed by examining a subset of the eigensystem using a method based on the Arnoldi process. The eigenvalues obtained by this method are accurate to within 5 digits for the largest ones and to within 2 digits for the ones smaller in magnitude compared the …

Oxidative Degradation Of Glucose Adducts To Protein: Formation Of 3-(NE-Lysino)-Lactic Acid From Model Compounds And Glycated Proteins, Mahtab U. Ahmed, John A. Dunn, Michael D. Walla, Suzanne R. Thorpe, John W. Baynes

Faculty Publications

The chemistry of Maillard or browning reactions of glycated proteins is being studied in model systems in vitro in order to characterize potential reaction pathways and products in biological systems. In previous work with the Amadori rearrangement product N alpha-formyl-N epsilon-fructoselysine (fFL), an analog of glycated lysine residues in proteins, we showed that fFL was oxidatively cleaved between C-2 and C-3 of the carbohydrate chain to yield N epsilon-carboxymethyllysine (CML) and D-erythronic acid. We then detected CML in proteins glycated in vitro, as well as in human lens proteins and collagen in vivo (Ahmed, M. U., Thorpe, S. R., and …

How Do Harpacticoid Grazing Rates Differ Over A Tidal Cycle? Field Verification Using Chlorophyll-Pigment Analyses, Alan W. Decho

Faculty Publications

Four species of meiobenthic copepods were examined for diatom feeding. Microscopic analysis of gut-pellet contents from field-collected individuals indicated frequent ingestion of diatoms by 3 harpacticoids (Scottolana canadensis, Microarthridion littorale, Cletocamptus deitersi) while occasional diatom ingestion occurred Paronychocamptus huntsmani. Frustules were usually empty and broken, indicating that contents were digested. Laboratory experiments using ¹⁴C-labeling showed assimilation of diatoms by the 3 species examined. Field grazing rate studies were conducted over different portions of a tidal cycle using fluorescent chlorophyll-pigment analysis of gut-contents. Highest diatom consumption (p<0.05) occurred just after the mudflat became exposed (i.e. Early Low Water level, ELW) for S. canadensis, while consumption at Late Low Water …

Experimental Study Of Nonlinear Conductance In Small Metallic Samples, Richard A. Webb, S. Washburn, C. P. Umbach

Faculty Publications

We have directly observed current-dependent, nonlinear contributions to the conductance fluctuations of phase-coherent metallic wires and loops. The fluctuations in the current-voltage curves are reproducible, asymmetric about I=0, and in qualitative agreement with theoretical predictions. In ac measurements, the nonlinear terms also generate large harmonic signals of the conductance fluctuations whose dependence on the drive current can be understood qualitatively. The spectra of harmonics from loops and wires have different dependences on the voltage across the sample.

A Cytochemical Study Of The Transcriptional And Translational Regulation Of Nuclear Transition Protein 1 (Tp1), A Major Chromosomal Protein Of Mammalian Spermatids, Mohammad A. Heidaran, Richard M. Showman, Wilson Stephen Kistler

Faculty Publications

Immunocytochemical localization and in situ hybridization techniques were used to investigate the presence of spermatid nuclear transition protein 1 (TP1) and its mRNA during the various stages of spermatogenesis in the rat. A specific antiserum to TP1 was raised in a rabbit and used to show that TP1 is immunologically crossreactive among many mammals including humans. During spermatogenesis the protein appears in spermatids as they progress from step 12 to step 13, a period in which nuclear condensation is underway. The protein is lost during step 15. An asymmetric RNA probe generated from a TP1 cDNA clone identified TP1 mRNA …

Dissipative Quantum Tunneling: Quantum Langevin Equation Approach, G. W. Ford, J. T. Lewis, R. F. O'Connell

Faculty Publications

The quantum Langevin equation is used as the basis for a discussion of dissipative quantum tunneling. A general analysis, including strong coupling and non-markovian (memory) effects, is given for the case of tunneling through a parabolic barrier at zero temperature in the presence of linear passive dissipation. It is shown that dissipation always decreases the tunneling rate below the barrier and increases transmission above the barrier. As a particular application, the case of the resistively shunted Josephson junction is considered. Simple closed form expressions for the tunneling rate and for the noise power spectrum are obtained and compared with results …

Prevention And Health Economics, Harold H. Gardner

Faculty Publications

The relationship between doctors and patients in the medical and health field is a topic of recurrent discussion today. The topic is of immense interest because of the questions raised about value received for services purchased and because of the large amount of economic resource consumed. The size of the stakes are such that the debate will grow in the near future until some solution is found to remedy the value and cost for service dilemma.

The Economics Of Public Assistance For Private Nonindustrial Timber Sales In Mississippi, Steven H. Bullard, Robert J. Moulton

Faculty Publications

The U.S. South has many forestry advantages, yet public and private efforts are increasingly needed to encourage reforestation and active forest management in the region. The review draft of "The South's Fourth Forest, Alternatives for the Future" (USDA Forest Service 1987a) highlights the urgent need for increased efforts to ensure future timber availability:

... projections of resource change mean that the South is facing a future of rising stumpage and roundwood product prices, much lower rates of growth in timber harvests, and declines in employment in the forest industries" (p. xxxv).

The report also highlights great opportunities to increase forest …

Southern Pine Beetle And Fire In Wilderness Areas: The Kisatchie Hills Wilderness, Kisatchie National Forest, David Kulhavy, William G. Ross

Faculty Publications

Southern pine beetle infestations affect wilderness areas in the southeastern United States. In the Kisatchie Hills Wilderness area in Louisiana, a southern pine 'beetle outbreak resulted in widespread destruction of longleaf pine. Nest trees of the red-cockaded woodpecker, an endangered species, also were killed. Following the epidemic, a fire fueled by beetle-killed pines went through the wilderness. Forest structure, species composition, successional processes and general ecosystem function were substantially altered as a result of these two related disturbances. Most wilderness areas containing southern pines were managed for pine timber before being designated as wilderness. Bark beetle outbreaks are a predictable …

The Mississippi Economic Council (1988), for example, recently labeled the state "The New Furniture Capital of America;' and Northeast Mississippi was recently described as a "booming region'' that "wants to be the Furniture Capital of America'' (Evans 1987). The present report characterizes important aspects of Mississippi's furniture industry, including its development and relative importance within the state and within the U.S., and assesses current information on the availability and use …

Marsh Management Plans In Practice: Do They Work In Coastal Louisiana, Usa?, James H. Cowan Jr., R. Eugene Turner, Donald R. Cahoon

Faculty Publications

Louisiana's coastal wetlands represent about 41% of the nation's total and are extensively managed for fish, fur, and waterfowl. Marsh management plans (MMPs) are currently used to avoid potential user conflicts and are believed to be a best management practice for specific management goals. In this article, we define MMPs and examine their variety, history, impacts, and future.

A MMP is an organized written plan submitted to state and federal permitting agencies for approval and whose purpose is to regulate wetland habitat quantity and quality (control land loss and enhance productivity). MMPs are usually implemented by making structural modifications in …

Protecting Waste Assimilation Streamflows By The Law Of Water Allocation, Nuisance, And Public Trust, And By Environmental Statutes, Peter N. Davis

Faculty Publications

Both federal and state water pollution control statutes require dramatic reductions in waste discharges, but not their total elimination. Those statutes require establishing water quality standards for receiving waters and presume that they will be adequate to assimilate the residual post treatment wastes. But nothing is those statutes assures that minimum flows for waste assimilation in fact will remain in existence. Neither the common law nor eastern and western diversion permit statutes expressly provide direct means for establishing such minimum protected flows for residual waste assimilation. Those means include establishing minimum flows for fish and wildlife habitat and recreation purposes …
