On Packing Minors Into Connected Matroids, Manoel Lemos, James Oxley

Faculty Publications

Let N be a matroid with k connected components and M be a minor-minimal connected matroid having N as a minor. This note proves that |E(M) - E(N)| is at most 2k - 2 unless N or its dual is free, in which case |E(M) - E(N)| ≤k - 1. Examples are given to show that these bounds are best possible for all choices for N. A consequence of the main result is that a minimally connected matroid of rank r and maximum circuit size c has at most 2r - c + 2 elements. This bound sharpens a result …

Influence Of Ash Deposit Chemistry And Structure On Physical And Transport Properties, Larry Lin Baxter 8507091

Faculty Publications

Boiler ash deposits generated during combustion of coal, biomass, black liquor, and energetic materials affect both the net plant efficiency and operating strategy of essentially all boilers. Such deposits decrease convective and radiative heat exchange with boiler heat transfer surfaces. In many cases, even a small amount of ash on a surface decreases local heat transfer rates by factors of three or more. Apart from their impact on heat transfer, ash deposits in boilers represent potential operational problems and boiler maintenance issues, including plugging, tube wastage (erosion and corrosion), and structural damage. This report relates the chemistry and microstructural properties …

Role Of The Maillard Reaction In Aging Of Tissue Proteins: Advanced Glycation End Product-Dependent Increase In Imidazolium Cross-Links In Human Lens Proteins, Elisabeth Brinkmann Frye, Thorsten P. Degenhardt, Suzanne R. Thorpe, John W. Baynes

Faculty Publications

Dicarbonyl compounds such as glyoxal and methylglyoxal are reactive dicarbonyl intermediates in the nonenzymatic browning and cross-linking of proteins during the Maillard reaction. We describe here the quantification of glyoxal and methylglyoxal-derived imidazolium cross-links in tissue proteins. The imidazolium salt cross-links, glyoxal-lysine dimer (GOLD) and methylglyoxal-lysine dimer (MOLD), were measured by liquid chromatography/mass spectrometry and were present in lens protein at concentrations of 0. 02-0.2 and 0.1-0.8 mmol/mol of lysine, respectively. The lens concentrations of GOLD and MOLD correlated significantly with one another and also increased with lens age. GOLD and MOLD were present at significantly higher concentrations than the …

Temporal Coherence Of Ultrashort High-Order Harmonic Pulses, M. Bellini, C. Lyngå, A. Tozzi, M. B. Gaarde, T. W. Hänsch, A. L'Huillier, C. G. Wahlström

Faculty Publications

We have studied the temporal coherence of high-order harmonics (up to the 15th order) produced by focusing 100 fs laser pulses into an argon gas jet. We measure the visibility of the interference fringes, produced when two spatially separated harmonic sources interfere in the far field, as a function of the time delay between the two sources. In general, we find long coherence times, comparable to the expected pulse durations of the harmonics. For some of the harmonics, the interference pattern exhibits two regions, with significantly different coherence times. These results are interpreted in terms of different electronic trajectories contributing …

Adrenomedullin Gene Expression Is Developmentally Regulated And Induced By Hypoxia In Rat Ventricular Cardiac Myocytes, Stephania Cormier-Regard, Son V. Nguyen, William C. Claycomb

Faculty Publications

Adrenomedullin is a recently discovered hypotensive peptide that is expressed in a variety of cell and tissue types. Using the technique of differential display, the adrenomedullin gene was observed to be differentially expressed in developing rat heart. Reverse transcription- polymerase chain reaction analysis revealed that the level of adrenomedullin mRNA was significantly higher in adult ventricular cardiac muscle as compared with embryonic day 17 ventricular cardiac muscle. Adrenomedullin receptor mRNA was constitutively expressed throughout development of the ventricular heart. Two potential hypoxia-inducible factor-1 (HIF-1) consensus binding sites were identified in the mouse adrenomedullin promoter at -1095 and -770 nucleotides from …

God, Christ, And All Things In 1 Corinthians 15:28, David E. Fredrickson

Faculty Publications

God's becoming "all in all" requires neither God's absolute sovereignty over all things nor the absorption of God into creation. In the New Testament, as in trinitarian theology, it is better understood as a way to speak of a personal relation between Creator and creation and between the Father and the Son.

The Trinity And Congregational Planning: Between Historical Minimum And Eschatological Maximum, Patrick R. Keifert

Faculty Publications

Most members of congregations are inattentive to both the past and the future of their congregation. They live in a very present now. An adequate doctrine of the Trinity can liberate congregations from this imprisonment in the present; it will call for visioning and planning in congregational life.

Binary Multilevel Convolutional Codes With Unequal Error Protection Capabilities, Robert H. Morelos-Zaragoza, Hideki Imai

Faculty Publications

Binary multilevel convolutional codes (CCs) with unequal error protection (UEP) capabilities are studied. These codes belong to the class of generalized concatenated (GC) codes. Binary CCs are used as outer codes. Binary linear block codes of short length, and selected subcodes in their two-way subcode partition chain, are used as inner codes. Multistage decodings are presented that use Viterbi decoders operating on trellises with similar structure to that of the constituent binary CCs. Simulation results of example binary two-level CC's are also reported.

No Trinity, No Mission: The Apostolic Difference Of Revisioning The Trinity, Gary M. Simpson

Moral and experiential monotheism, twin bequests of the enlightenment, have robbed recent doctrines of God of an essential apostolic difference. A revisioned formulation of the Trinity will provide good news for the modern world.

Understanding Congressional Reform: Lessons From The Seventies, Rafael Gely, Asghar Zardkoohi

Faculty Publications

The purpose of this article is to examine voting behavior of representatives when faced with dual constraints (constituents back home and the leadership) as compared to one constraint (constituents back home). An ambitious goal of the study would have been to examine the effects of both sets of reforms. However, there are two reasons for not using the 1995 reforms in our empirical examinations. First, not enough time has passed to fully observe the effect of term limits on voting behavior. Second, and more importantly, the leadership, whose power it was to impose a constraint on a representative's promotional opportunities, …

Assembly Of A High-Resolution Map Of The Acadian Usher Syndrome Region And Localization Of The Nuclear Ef-Hand Acidic Gene, Margaret M. Deangelis, John P. Doucet, Stacy Drury, Stephen T. Sherry, Myles B. Robichaux, Zhining Den, Mary Z. Pelias, Gregory M. Ditta, Bronya J.B. Keats, Prescott L. Deininger, Mark A. Batzer

Faculty Publications

Usher syndrome type 1C (USH1C) occurs in a small population of Acadian descendants from southwestern Louisiana. Linkage and linkage disequilibrium analyses localize USH1C to chromosome 11p between markers D11S1397 and D11S1888, an interval of less than 680 kb. Here, we refine the USH1C linkage to a region less than 400 kb, between genetic markers D11S1397 and D11S1890. Using 17 genetic markers from this interval, we have isolated a contiguous set of 60 bacterial artificial chromosomes (BACs) that span the USH1C critical region. Exon trapping of BAC clones from this region resulted in the recovery of an exon of the nuclear …

One enzyme which catalyzes the last step of the formation of the hormone retinoic acid from vitamin A (retinol) is retinal dehydrogenase type II (RalDH2). RalDH2, expressed in the Escherichia coil BL21(DE3) strain, was purified and crystallized using ammonium sulfate as a precipitant. These crystals belong to the space group P212121 (a = 108, b = 150, c = 168 Å, α = β = γ = 90°).

Replication Banding And Sister-Chromatid Exchange Of Chromosomes Of Channel Catfish (Ictalurus Punctatus), Q. Zhang, W. R. Wolters, T. R. Tiersch

Faculty Publications

A replication banding procedure using fluorouracil (FU) and bromodeoxyuridine (BrdU) was developed for use with cultured leukocytes of channel catfish (Ictalurus punctatus). Analyzable banding patterns were produced on chromosomes stained with a fluorochrome plus Giemsa (FPG) method. The consistency of the chromosomal bands was evaluated by computer-assisted image analysis. Banding patterns of representative chromosomes including those bearing nucleolus organizer regions (NOR) were reproducible. A standard RBG-banded karyotype (R bands by BrdU and Giemsa) was established with idiograms of each chromosome. We also developed procedures to study sister- chromatid exchange (SCE) and sister-chromatid differentiation (SCD) in cultured leukocytes, without addition of …

Self-Enforcing Union Contracts: Efficient Investment And Employment, John T. Addison, John B. Chilton

Faculty Publications

Baldwin (1983) asks whether a firm can credibly deter union opportunism that would lead to underinvestment. We show that the punishments Baldwin considers credible exclude tougher threats that only have the appearance of being self-destructive. If the firm's discount factor is sufficiently close to one, union opportunism can indeed be deterred. Moreover, we show that given the firm's discount factor, a shorter lifetime of capital does not necessarily promote efficiency. Although, as Baldwin emphasizes, it does enhance the firm's ability to punish union opportunism, it also creates adverse incentives for the firm to engage in opportunistic employment cuts.

Generating Needed Modernization Funds: Streamlining The Bureaucracy--Not Outsourcing And Privatizing--Is The Best Solution, Jan P. Muczyk

Faculty Publications

The Department of Defense (DoD) budget, in real dollars, has decreased for a dozen years or so, and will likely continue to do so. Since all the funds necessary for warfighting asset modernization will not come from Congress, DoD must free up existing funds for reallocation to its modernization program. So far, much reliance has been placed on privatization and outsourcing as ways of releasing large sums of money. But it is highly unlikely that these instrumentalities are up to the task, and other sources must shoulder a large part of the load. Although eliminating duplication of mission and roles …

Race, Redlining, And Automobile Insurance Prices, Scott E. Harrington, Gregory R. Niehaus

Faculty Publications

Following Becker's (1993) suggestion that tests for discrimination should attempt to infer whether profits differ for products sold to minorities and nonminorities, this article tests the hypothesis that racial discrimination affects market prices of auto insurance in Missouri. Compared with tests for discrimination in lending markets, our results are less susceptible to bias from omitted variables.Controlling for available demographic and coverage- related factors, we do not find that loss ratios at the zip-code level are negatively related to percent minority population. This finding is inconsistent with the hypothesis that racial discrimination increases premiums relative to expected claim costs for minorities.

Status Processes And Mental Ability Test Scores, Michael J. Lovaglia, Jeffrey W. Lucas, Jeffrey A. Houser, Shane R. Thye, Barry N. Markovsky

Faculty Publications

The expected consequences of a score on an ability test can constrain individual performance. The authors predict that status processes, including status differences and the differences in rewards and costs that result, will produce differences in ability test scores between high-status and low-status individuals. In three controlled experi- ments, participants randomly assigned low status scored lower on a standard test of mental ability (the Raven Progressive Matrices) than did participants assigned high status. For both men and women, the difference in ability test score between low-status and high-status participants was about half a standard deviation. The results suggest the need …

Successive Galerkin Approximations To The Nonlinear Optimal Control Of An Underwater Robotic Vehicle, Timothy Mclain, Randal W. Beard

Faculty Publications

The application of a new nonlinear optimal control strategy to the station-keeping control of an underwater robotic vehicle is considered. The control approach described and demonstrated here is based upon the numerical approximation of solutions to the Hamilton-Jacobi-Bellman equation. These solutions are computed by an iterative application of Galerkin's method. Preliminary simulation results demonstrating the application of this approach to the control of an underwater vehicle in the horizontal plane are presented.

Development And Experimental Validation Of An Underwater Manipulator Hydrodynamic Model, Timothy W. Mclain, Stephen M. Rock

Faculty Publications

Hydrodynamic forces can be large and hence have a significant effect on the dynamic performance of underwater manipulation systems. this paper investigates these forces for a cylindrical single-link arm undergoing motions that are characteristics of a robotic manipulator. Based on flow visualization, theoretical analysis, and experimental measurements, a new model is developed that describes these forces. This model differs from previous models in that the drag and added-mass coefficients are state-dependent functions that depend on the distance traveled by the arm. A factor of four improvement in accuracy is demonstrated over standard constant-coefficient models.

Smith On Hanley, 'The Metaphysics Of Star Trek, Anne Collins Smith

Faculty Publications

Review by Anne Collins Smith on the H-PCAACA mailing list, June 1998.

The Metaphysics of Star Trek by Richard Hanley. New York: Basic Books, 1997. xviii + 253 pp. $18.00 (cloth), ISBN 978-0-465-09124-9.

Richard Hanley's The Metaphysics of Star Trek is an engaging examination of certain philosophical issues raised within the Star Trek universe. Its title, however, is overly broad; it would be more correctly titled, The Twentieth-Century Applied Metaphysics of Star Trek. The earliest reference in the bibliography is an article written in 1950; the next earliest, 1960. The vast majority of sources are from the 1980's and …

Solute-Solvent Pair Distribution Functions In Highly Asymmetric Additive Hard Sphere Mixtures, Douglas Henderson, Kwong-Yu Chan

Faculty Publications

Contact values for the solute-solvent pair distribution function in an additive hard sphere mixture, as computed from the Henderson-Chan (HC) formulas, are compared with the recent Monte Carlo (MC) data and formula of Matyushov and Ladanyi (ML) [J. Chem. Phys. 107, 5815 (1997)]. The agreement is found to be excellent. The negative finding of ML is due to a misprint in one of the HC publications. We find the HC formula to be superior to the ML formula when compared to our MC data [Mol. Phys. 91, 1137 (1997)] for the case where the ratio of diameters is large and …

Structure And Elasticity Of Cao At High Pressure, Bijaya B. Karki, Jason Crain

Faculty Publications

We investigate the structural and elastic properties of CaO up to 140 GPa using the plane wave pseudopotential method within the local density approximation. Free energy comparison suggests that the transition from the low-pressure sodium chloride (B1) to the high-pressure cesium chloride (B2) structure in CaO occurs at 58 GPa, which falls within the experimental range of 53-70 GPa. The zero-pressure values and initial pressure dependences of the calculated athermal elastic moduli compare favorably with the experiments. We find that the elastic properties of the two phases vary differently with pressure. The degree of the anisotropy strongly increases with pressure …
