Interfering Solutions Of A Nonhomogeneous Hamiltonian System, Gregory S. Spradlin Jun 2001

Interfering Solutions Of A Nonhomogeneous Hamiltonian System, Gregory S. Spradlin

Publications

A Hamiltonian system is studied which has a term approaching a constant at an exponential rate at infinity. A minimax argument is used to show that the equation has a positive homoclinic solution. The proof employs the interaction between translated solutions of the corresponding homogeneous equation. What distinguishes this result from its few predecessors is that the equation has a nonhomogeneous nonlinearity.

Spin Glass Phase In Spin-Density-Wave Cr–Co Alloys, V. Yu. Galkin, N. Ali, W. A. Ortiz, E. Fawcett Jun 2001

Spin Glass Phase In Spin-Density-Wave Cr–Co Alloys, V. Yu. Galkin, N. Ali, W. A. Ortiz, E. Fawcett

Publications

A spin glass (SG) phase was observed in the spin-density wave (SDW) alloys Cr1−xCox at high Co concentrations (x≥13%). After zero-field cooling, the temperature dependence of the magnetization M(T) of Cr0.87Co0.13 and Cr0.85Co0.15, measured in an applied field H=100 Oe with a SQUID magnetometer, exhibits a low T maximum, characteristic of a SG. Cooling in the measuring field, however, gives quite a different behavior. The field dependence of the magnetization M(H) is nonlinear, with a pronounced hysteresis. A strong time …

Magnetic Properties Of Lacr1−Xmxsb3 (M=V, Mn, Fe, Cu, And Al), I. S. Dubenko, P. Hill, N. Ali Jun 2001

Magnetic Properties Of Lacr1−Xmxsb3 (M=V, Mn, Fe, Cu, And Al), I. S. Dubenko, P. Hill, N. Ali

Publications

The influence of Cr substitution by various metals (M=V, Mn, Fe, Cu and Al) on the magnetic state of the itinerant intermetallics La(Cr,M)Sb3 was studied by magnetization and magnetic susceptibility measurements up to 55 kG at 5 K and from 4.2 to 400 K, in a magnetic field of 1000 G, respectively. It was found that the Curie temperature (TC) and magnetization (M) of these compounds depend nonlinearly on the concentration, remaining in the vicinity of the values of TC and M measured for LaCrSb3. Curie temperatures and magnetization values at …

Charge Transport And Colossal Magnetoresistance Phenomenon In La1−Xzrxmno3, Sujoy Roy, Naushad Ali Jun 2001

Charge Transport And Colossal Magnetoresistance Phenomenon In La1−Xzrxmno3, Sujoy Roy, Naushad Ali

Publications

In this study we have investigated the magnetic and electrical transport properties of Zr doped lanthanum manganite perovskite. The structural, magnetic, and transport properties of the Zr doped compounds were determined using x-ray diffraction, dc magnetic susceptibility, and a four probe method for electrical resistivity and magnetoresistance measurements in the temperature range of 5–400 K. The structure of the compounds was found to be rhombohedral. The magnetization versus temperature curves show ferromagnetic regions with the magnetic transition temperatures getting saturated for x ≥ 0.07 compounds. The resistivity curves show decreasing resistivity with increasing Zr content in the compound. The resistivity …

Developing Better Economic Information About Coastal Resources As A Tool For Integrated Coastal Management, Judith T. Kildow Dr, Brian Baird, Charles S. Colgan, Hauke Kite-Powell, Rodney Weiher Apr 2001

Developing Better Economic Information About Coastal Resources As A Tool For Integrated Coastal Management, Judith T. Kildow Dr, Brian Baird, Charles S. Colgan, Hauke Kite-Powell, Rodney Weiher

Publications

Measuring economic activity associated with the ocean through examination of the goods and services produced by specified industries and in coastal locations will provide answers to many of the most commonly asked questions about the ocean economy. But even this data will still be incomplete. Beyond are a variety of "non-market" values, which are needed to complete the picture. When someone goes to the beach in Florida or boats on Chesapeake Bay, there may be little that is directly purchased on that day. But the popularity of such activities is testament to their underlying value. Economists have developed a variety …

Veribly A Purple Cow: The Whole Family And The Collaborative Search For Coherence, Susanna Ashton Apr 2001

Veribly A Purple Cow: The Whole Family And The Collaborative Search For Coherence, Susanna Ashton

Publications

As attested to by its very name, The Whole Family was a project concerned with coherence. Published serially in Harper's Bazar from 1907-1908, this collaborative novel was a remarkable instance of narrative structure assembled by editor Elizabeth Jordan. Featuring chapters by William Dean Howells, Mary Wilkins Freeman, Henry James, Elizabeth Stuart Phelps, Mary Stuart Cutting, John Kendrick Bangs, Henry van Dyke, Alice Brown, Mary Heaton Vorse, Edith Wyatt, Mary Shipman Andrews, and Elizabeth Jordan herself, the novel garnered considerable attention when it first appeared, with the acclaim usually citing The Whole Family's surprisingly coherent qualities as key to its success. …

Climatology And Modeling Of Quasi-Monochromatic Atmospheric Gravity Waves Observed Over Urbana Illinois, J. H. Hecht, R. L. Walterscheid, Michael P. Hickey Ph.D., S. J. Franke Mar 2001

Climatology And Modeling Of Quasi-Monochromatic Atmospheric Gravity Waves Observed Over Urbana Illinois, J. H. Hecht, R. L. Walterscheid, Michael P. Hickey Ph.D., S. J. Franke

Publications

From analyzing nine months of airglow imaging observations of atmospheric gravity waves (AGWs) over Adelaide, Australia (35°S) [Walterscheid et al., 1999] have proposed that many of the quasi-monochromatic waves seen in the images were primarily thermally ducted. Here are presented 15 months of observations, from February 1996 to May 1997, for AGW frequency and propagation direction from a northern latitude site, Urbana Illinois (40°N). As Adelaide, Urbana is geographically distant from large orographic features. Similar to what was found in Adelaide, the AGWs seem to originate from a preferred location during the time period around summer solstice. In …

Multimedia And Engaged Reading In A Digital World, David Reinking Mar 2001

Multimedia And Engaged Reading In A Digital World, David Reinking

Publications

Anyone who has spent more than a few minutes “surfing the ‘net” has an intuitive awareness of how different it feels to encounter textual information in a digital as opposed to a typographic environment. The inert features of the printed page that make reading essentially a solitary psycholinguistic process and only incidentally a visual one, as Goodman argued many years ago, are transformed on the computer screen to make reading more dynamic, more interactive, more essentially visual, and even auditory. In comparison, the experience of reading printed materials, especially books, as Richard Lanham (1993) has argued, is static, silent, introspective, …

A Disease By Any Other Name: Musings On The Concept Of A Genetic Disease, Kelly C. Smith Mar 2001

A Disease By Any Other Name: Musings On The Concept Of A Genetic Disease, Kelly C. Smith

Publications

What exactly is a genetic disease? For a phrase one hears on a daily basis, there has been surprisingly little analysis of the underlying concept. Medical doctors seem perfectly willing to admit that the etiology of disease is typically complex, with a great many factors interacting to bring about a given condition. On such a view, descriptions of diseases like cancer as genetic seem at best highly simplistic, and at worst philosophically indefensible. On the other hand, there is clearly some practical value to be had by classifying diseases according to their predominant cause when this can be accomplished …

Gravity Wave Propagation Directions Inferred From Satellite Observations Including Smearing Effects, Jason S. Brown, Michael P. Hickey Ph.D. Mar 2001

Gravity Wave Propagation Directions Inferred From Satellite Observations Including Smearing Effects, Jason S. Brown, Michael P. Hickey Ph.D.

Publications

We simulate space-based, sublimb viewing observations of airglow brightness fluctuations caused by atmospheric gravity wave interactions with the O2 atmospheric airglow, and we demonstrate that because of the geometry associated with such observations, the brightness fluctuations observed for the optically thick 0–0 band emission will always appear stronger for waves traveling toward the observer (the satellite). The effect should be most noticeable for waves having relatively small vertical wavelengths (∼10 km) and horizontal wavelengths of 50 km or greater. For waves of short (∼100 km) horizontal wavelength, the brightness fluctuation anisotropy with respect to viewing direction may also be evident …

A Determination Of The Local Density Of White Dwarf Stars, J. B. Holberg, Terry D. Oswalt, E. M. Sion Feb 2001

A Determination Of The Local Density Of White Dwarf Stars, J. B. Holberg, Terry D. Oswalt, E. M. Sion

Publications

The most recent version of the Catalog of Spectroscopically Identified White Dwarfs lists 2249 white dwarf stars. Among these stars are 109 white dwarfs that have either reliable trigonometric parallaxes or color-based distance moduli that place them at a distance within 20 pc of the Sun. Most of these nearby white dwarfs are isolated stars, but 28 (25% of the sample) are in binary systems, including such well-known systems as Sirius A/B and Procyon A/B. There are also three double degenerate systems in this sample of the local white dwarf population. The sample of local white dwarfs is largely complete …

A Human Error Analysis Of Commercial Aviation Accidents Using The Human Factors Analysis And Classification System (Hfacs), Douglas A. Wiegmann, Scott A. Shappell Feb 2001

A Human Error Analysis Of Commercial Aviation Accidents Using The Human Factors Analysis And Classification System (Hfacs), Douglas A. Wiegmann, Scott A. Shappell

Publications

The Human Factors Analysis and Classification System (HFACS) is a general human error framework originally developed and tested within the U.S. military as a tool for investigating and analyzing the human causes of aviation accidents. Based upon Reason’s (1990) model of latent and active failures, HFACS addresses human error at all levels of the system, including the condition of aircrew and organizational factors. The purpose of the present study was to assess the utility of the HFACS framework as an error analysis and classification tool outside the military. Specifically, HFACS was applied to commercial aviation accident records maintained by the …

Ebna1-Specific Cd4+ T Cells In Healthy Carriers Of Epstein-Barr Virus Are Primarily Th1 In Function, Kara L. Bickham, Christian Münz, Mingli Tsang Jan 2001

Ebna1-Specific Cd4+ T Cells In Healthy Carriers Of Epstein-Barr Virus Are Primarily Th1 In Function, Kara L. Bickham, Christian Münz, Mingli Tsang

Publications

The Epstein-Barr virus (EBV) nuclear antigen-1 (EBNA1) maintains the viral episome in all host cells infected with EBV. Recently, EBNA1 was found to be the main EBV latency antigen for CD4+ T cells and could be recognized in cultures from all donors tested. We now identify a polarized Th1 phenotype and obtain evidence for its presence in vivo. When T cells were stimulated with dendritic cells infected with vaccinia vectors expressing EBNA1, 18 of 19 donors secreted IFN-γ, whereas only two of 19 secreted IL-4. Magnetic selection was then used to isolate cells from fresh blood based on EBNA1-induced …

Mature Dendritic Cells Infected With Canarypox Virus Elicit Strong Anti-Human Immunodeficiency Virus Cd8+ And Cd4+ T-Cell Responses From Chronically Infected Individuals, Jose Engelmayer, Marie C. Larsson, Andrew W. Lee Jan 2001

Mature Dendritic Cells Infected With Canarypox Virus Elicit Strong Anti-Human Immunodeficiency Virus Cd8+ And Cd4+ T-Cell Responses From Chronically Infected Individuals, Jose Engelmayer, Marie C. Larsson, Andrew W. Lee

Publications

Recombinant canarypox virus vectors containing human immunodeficiency virus type 1 (HIV-1) sequences are promising vaccine candidates, as they replicate poorly in human cells. However, when delivered intramuscularly the vaccines have induced inconsistent and in some cases transient antigen-specific cytotoxic T-cell (CTL) responses in seronegative volunteers. An attractive way to enhance these responses would be to target canarypox virus to professional antigen-presenting cells such as dendritic cells (DCs). We studied (i) the interaction between canarypox virus and DCs and (ii) the T-cell responses induced by DCs infected with canarypox virus vectors containing HIV-1 genes. Mature and not immature DCs resisted the …

Antigen-Specific Inhibition Of Effector T Cell Function In Humans After Injection Of Immature Dendritic Cells, Madhav V. Dhodapkar, Ralph M. Steinman, Joseph Krasovsky Jan 2001

Antigen-Specific Inhibition Of Effector T Cell Function In Humans After Injection Of Immature Dendritic Cells, Madhav V. Dhodapkar, Ralph M. Steinman, Joseph Krasovsky

Publications

Immunostimulatory properties of dendritic cells (DCs) are linked to their maturation state. Injection of mature DCs rapidly enhances antigen-specific CD4+ and CD8+ T cell immunity in humans. Here we describe the immune response to a single injection of immature DCs pulsed with influenza matrix peptide (MP) and keyhole limpet hemocyanin (KLH) in two healthy subjects. In contrast to prior findings using mature DCs, rejection of immature DCs in both subjects led to the specific inhibition of MP-specific CD8+ T cell effector function in freshly isolated T cells and the appearance of MP-specific interleukin 10-producing cells. When pre-and …

T Cell Studies In A Peptide-Induced Model Of Systemic Lupus Erythematosus, Magi Khalil, Kayo Inaba, Ralph M. Steinman Jan 2001

T Cell Studies In A Peptide-Induced Model Of Systemic Lupus Erythematosus, Magi Khalil, Kayo Inaba, Ralph M. Steinman

Publications

We have previously reported that immunization with a peptide mimetope of dsDNA on a branched polylysine backbone (DWEYSVWLSN-MAP) induces a systemic lupus erythematosus-like syndrome in the nonautoimmune BALB/c mouse strain. To understand the mechanism underlying this breakdown in self tolerance, we examined the role of T cells in the response. Our results show that the anti-foreign and anti-self response induced by immunization is T cell dependent and is mediated by I-Ed-restricted CD4+ T cells of the Th1 subset. In addition, generation of the critical T cell epitope requires processing by APCs and depends on the presence of …

Dendritic Cells Cross-Present Latency Gene Products From Epstein-Barr Virus-Transformed B Cells And Expand Tumor-Reactive Cd8+ Killer T Cells, Marion S. Subklewe, Casoer Paludan, Mingli Tsang Jan 2001

Dendritic Cells Cross-Present Latency Gene Products From Epstein-Barr Virus-Transformed B Cells And Expand Tumor-Reactive Cd8+ Killer T Cells, Marion S. Subklewe, Casoer Paludan, Mingli Tsang

Publications

Dendritic cells (DCs) are not targets for infection by the transforming Epstein-Barr virus (EBV). To test if the adjuvant role of DCs could be harnessed against EBV latency genes by cross-presentation, DCs were allowed to process either autologous or human histocompatibility leukocyte antigen (HLA)-mismatched, transformed, B lymphocyte cell lines (LCLs) that had been subject to apoptotic or necrotic cell death. After phagocytosis of small numbers of either type of dead LCL, which lacked direct immune-stimulatory capacity, DCs could expand CD8+ T cells capable of killing LCLs that were HLA matched to the DCs. Necrotic EBV-transformed, major histocompatibility complex (MHC) …

Dendritic Cells Induce Peripheral T Cell Unresponsiveness Under Steady State Conditions In Vivo, Daniel Hawiger, Kayo Inaba, Yair Dorsett Jan 2001

Dendritic Cells Induce Peripheral T Cell Unresponsiveness Under Steady State Conditions In Vivo, Daniel Hawiger, Kayo Inaba, Yair Dorsett

Publications

Dendritic cells (DCs) have the capacity to initiate immune responses, but it has been postulated that they may also be involved in inducing peripheral tolerance. To examine the function of DCs in the steady state we devised an antigen delivery system targeting these specialized antigen presenting cells in vivo using a monoclonal antibody to a DC-restricted endocytic receptor, DEC-205. Our experiments show that this route of antigen delivery to DCs is several orders of magnitude more efficient than free peptide in complete Freund's adjuvant (CFA) in inducing T cell activation and cell division. However, T cells activated by antigen delivered …

Downscaling Temperature And Precipitation: A Comparison Of Regression-Based Methods And Artificial Neural Networks, Justin T. Schoof, S C. Pryor Jan 2001

Downscaling Temperature And Precipitation: A Comparison Of Regression-Based Methods And Artificial Neural Networks, Justin T. Schoof, S C. Pryor

Publications

A comparison of two statistical downscaling methods for daily maximum and minimum surface air temperature, total daily precipitation and total monthly precipitation at Indianapolis, IN, USA, is presented. The analysis is conducted for two seasons, the growing season and the non-growing season, defined based on variability of surface air temperature. The predictors used in the downscaling are indices of the synoptic scale circulation derived from rotated principal components analysis (PCA) and cluster analysis of variables extracted from an 18-year record from seven rawinsonde stations in the Midwest region of the United States. PCA yielded seven significant components for the growing …

Mechanics Of Limb Bone Loading During Terrestrial Locomotion In The Green Iguana (Iguana Iguana) And American Alligator (Alligator Mississippiensis), R. W. Blob, A. A. Biewener

Publications

In vivo measurements of strain in the femur and tibia of Iguana iguana (Linnaeus) and Alligator mississippiensis (Daudin) have indicated three ways in which limb bone loading in these species differs from patterns observed in most birds and mammals: (i) the limb bones of I. iguana and A. mississippiensis experience substantial torsion, (ii) the limb bones of I. iguana and A. mississippiensis have higher safety factors than those of birds or mammals, and (iii) load magnitudes in the limb bones of A. mississippiensis do not decrease uniformly with the use of a more upright posture. To verify these patterns, and …

Comparative Kinematics Of The Forelimb During Swimming In Red-Eared Slider (Trachemys Scripta) And Spiny Softshell (Apalone Spinifera) Turtles, Cinnamon M. Pace, Richard W. Blob, Mark W. Westneat Jan 2001

Comparative Kinematics Of The Forelimb During Swimming In Red-Eared Slider (Trachemys Scripta) And Spiny Softshell (Apalone Spinifera) Turtles, Cinnamon M. Pace, Richard W. Blob, Mark W. Westneat

Publications

Softshell turtles (Family Trionychidae) possess extensive webbing between the digits of the manus, suggesting that the forelimb may serve as an effective thrust generator during aquatic locomotion. However, the hindlimb has previously been viewed as the dominant propulsive organ in swimming freshwater turtles. To evaluate the potential role of the forelimb in thrust production during swimming in freshwater turtles, we compared the forelimb morphology and three-dimensional forelimb kinematics of a highly aquatic trionychid turtle, the spiny softshell Apalone spinifera, and a morphologically generalized emydid turtle, the red-eared slider Trachemys scripta. Spiny softshells possess nearly twice as much forelimb surface area …

Fine Root Productivity And Dynamics On A Forested Floodplain In South Carolina, William Conner, Terrell Baker, B. Graeme Lockaby, John A. Stanturf, Marianne K. Burke Jan 2001

Fine Root Productivity And Dynamics On A Forested Floodplain In South Carolina, William Conner, Terrell Baker, B. Graeme Lockaby, John A. Stanturf, Marianne K. Burke

Publications

The highly dynamic, fine-root component of forested wetland ecosystems has received inadequate attention in the literature. Characterizing fine root dynamics is a challenging endeavor in any system, but the difficulties are particularly evident in forested floodplains where frequent hydrologic fluctuations directly influence fine root dynamics. Fine root (< 3mm) biomass, production, and turnover were estimated for three soils exhibiting different drainage patterns within a mixed-oak community on the Coosawhatchie River floodplain, Jasper County, SC. Within a 45-cm deep vertical profile, 74% of total fine root biomass was restricted to the upper 15 cm of the soil surface. Fine root biomass decreased as the soil became less well-drained (e.g., fine root biomass in well-drained soil > intermediately drained soil > poorly drained soil). Fine root productivity was measured for one year using minirhizotrons and in-situ screens. Both methods suggested higher fine root production in better drained soils but showed frequent fluctuations in fine root growth and mortality, suggesting the need for frequent sampling at short intervals (e.g., monthly) to …

School Based Decision Making, Jane Clark Lindle Jan 2001

School Based Decision Making, Jane Clark Lindle

Publications

The 1989 Task Force on Education Reform adopted 12 systemic principles used in drafting the 1990 Kentucky Education Reform Act (KERA). One of the principles formed the basis for School Based Decision Making (SBDM). It stated: "School accountability and school-based authority are two intertwined parts of the same proposition" (Foster, 1999; Task Force on Education Reform, 1989, p. 2). In other words, once the Task Force selected schools as the unit for the commonwealth's new accountability and assessment system, the General Assembly agreed that schools should have statutory authority to plan and make policy addressing achievement of accountability goals. The …
