Discovery Of A Novel, Paternally Expressed Ubiquitin-Specific Processing Protease Gene Through Comparative Analysis Of An Imprinted Region Of Mouse Chromosome 7 And Human Chromosome 19q13.4, Joomyeong Kim, Vladimir N. Noskov, Xiaochen Lu, Anne Bergmann, Xiaojia Ren, Tiffany Warth, Paul Richardson, Natalya Kouprina, Lisa Stubbs

Faculty Publications

Using mouse BAC clones spanning an imprinted interval of proximal mouse chromosome 7 and the genomic sequence of the related interval of human chromosome 19q13.4, we have identified a novel mouse gene, Usp29 (ubiquitin-specific processing protease 29), near two known imprinted genes, Peg3 and Zim1. Gene Usp29 is located directly adjacent to Peg3 in a ″head-to-head″ orientation, and comprises exons distributed over a genomic distance of at least 400 kb. A similar human gene is also found in the homologous location in human chromosome 19q13.4. The mouse Usp29 gene is also imprinted and is transcribed mainly from the paternal allele …

High Phosphorylation Efficiency And Depression Of Uncoupled Respiration In Mitochondria Under Hypoxia, Erich Gnaiger, Gabriela Méndez, Steven C. Hand

Faculty Publications

Mitochondria are confronted with low oxygen levels in the microenvironment within tissues; yet, isolated mitochondria are routinely studied under air-saturated conditions that are effectively hyperoxic, increase oxidative stress, and may impair mitochondrial function. Under hypoxia, on the other hand, respiration and ATP supply are restricted. Under these conditions of oxygen limitation, any compromise in the coupling of oxidative phosphorylation to oxygen consumption could accentuate ATP depletion, leading to metabolic failure. To address this issue, we have developed the approach of oxygen-injection microcalorimetry and ADP-injection respirometry for evaluating mitochondrial function at limiting oxygen supply. Whereas phosphorylation efficiency drops during ADP limitation …

Response Of Atmospheric Methane Consumption By Maine Forest Soils To Exogenous Aluminum Salts, K. Nanba, G. M. King

Faculty Publications

Atmospheric methane consumption by Maine forest soils was inhibited by additions of environmentally relevant levels of aluminum. Aluminum chloride was more inhibitory than nitrate or sulfate salts, but its effect was comparable to that of a chelated form of aluminum. Inhibition could be explained in part by the lower soil pH values which resulted from aluminum addition. However, significantly greater inhibition by aluminum than by mineral acids at equivalent soil pH values indicated that inhibition also resulted from direct effects of aluminum per se. The extent of inhibition by exogenous aluminum increased with increasing methane concentration for soils incubated in …

On The Excluded Minors For Quaternary Matroids, J. F. Geelen, J. G. Oxley, D. L. Vertigan, G. P. Whittle

Faculty Publications

This paper strengthens the excluded-minor characterization of GF(4)-representable matroids. In particular, it is shown that there are only finitely many 3-connected matroids that are not GF(4)-representable and that have no U2, 6-, U4, 6-, P6-, F-7-, or (F-7)*-minors. Explicitly, these matroids are all minors of S(5, 6, 12) with rank and corank at least 4, and P″8, the matroid that can be obtained from S(5, 6, 12) by deleting two elements, contracting two elements, and then relaxing the only pair of disjoint circuit-hyperplanes. © 2000 Academic Press.

The Polarization Of Sb Overlayers On Nimnsb(100), Takashi Komesu, C. N. Borca, Hae Kyung Jeong, P. A. Dowben, Delia Ristoiu, J. P. Nozières, Shane Stadler, Y. U. Idzerda

Faculty Publications

We have investigated the induced polarization of paramagnetic Sb overlayers on the Heusler alloy NiMnSb. From combined X-ray absorption spectroscopy (XAS) and spin-polarized inverse photoemission spectroscopy (SPIPES), we can assign some of the unoccupied states of the Heusler alloy NiMnSb. With increasing thickness of the Sb overlayer, there is a decline in the density of states near the Fermi energy, as expected for a semimetal overlayer on a metallic substrate. While the Sb is polarized by the ferromagnetic NiMnSb substrate, consistent with the expectations of mean field theory, the polarization at the center of the surface/overlayer Brillouin zone cannot be …

Canonical Quantum Gravity In The Vassiliev Invariants Arena: I. Kinematical Structure, Cayetano Di Bartolo, Rodolfo Gambini, Jorge Griego, Jorge Pullin

Faculty Publications

We generalize the idea of Vassiliev invariants to the spin network context, with the aim of using these invariants as a kinematical arena for a canonical quantization of gravity. This paper presents a detailed construction of these invariants (both ambient and regular isotopic) requiring a significant elaboration based on the use of Chern - Simons perturbation theory which extends the work of Kauffman, Martin and Witten to four-valent networks. We show that this space of knot invariants has the crucial property - from the point of view of the quantization of gravity - of being loop differentiable in the sense …

Canonical Quantum Gravity In The Vassiliev Invariants Arena: Ii. Constraints, Habitats And Consistency Of The Constraint Algebra, Cayetano Di Bartolo, Rodolfo Gambini, Jorge Griego, Jorge Pullin

Faculty Publications

In a companion paper we introduced a kinematical arena for the discussion of the constraints of canonical quantum gravity in the spin network representation based on Vassiliev invariants. In this paper we introduce the Hamiltonian constraint, extend the space of states to non-diffeomorphism-invariant 'habitats' and check that the off-shell quantum constraint commutator algebra reproduces the classical Poisson algebra of constraints of general relativity without anomalies. One can therefore consider the resulting set of constraints and space of states as a consistent theory of canonical quantum gravity.

New Insights Into The Size And Stoichiometry Of The Plasminogen Activator Inhibitor Type-1·Vitronectin Complex, T. J. Podor, S. G. Shaughnessy, M. N. Blackburn, C. B. Peterson

Faculty Publications

Plasminogen activator inhibitor-type 1 (PAI-1) is the primary inhibitor of endogenous plasminogen activators that generate plasmin in the vicinity of a thrombus to initiate thrombolysis, or in the pericellular region of cells to facilitate migration and/or tissue remodeling. It has been shown that the physiologically relevant form of PAI-1 is in a complex with the abundant plasma glyco-protein, vitronectin. The interaction between vitronectin and PAI-1 is important for stabilizing the inhibitor in a reactive conformation. Although the complex is clearly significant, information is vague regarding the composition of the complex and consequences of its formation on the distribution and activity …

The X-Ray Transient Xte J1118+480: Multiwavelength Observations Of A Low-State Minioutburst, R. I. Hynes, C. W. Mauche, C. A. Haswell, C. R. Shrader, W. Cui, S. Chaty

Faculty Publications

We present multiwavelength observations of the newly discovered X-ray transient XTE J1118+480 obtained in the rising phase of the 2000 April outburst. This source is located at unusually high Galactic latitude and in a very low absorption line of sight. This made the first Extreme Ultraviolet Explorer (EUVE) spectroscopy of an X-ray transient outburst possible. Together with our Hubble Space Telescope, Rossi X-Ray Timing Explorer, and United Kingdom Infrared Telescope data, this gives unprecedented spectral coverage. We find the source in the low hard state. The flat IR-UV continuum appears to be a combination of optically thick disk emission and …

Mutational Analysis Of The Tra Locus Of The Broad-Host-Range Streptomyces Plasmid Pij101, Gregg S. Pettis, Stanley N. Cohen

Faculty Publications

The tra gene of Streptomyces lividans plasmid pIJ101 encodes a 621- amino-acid protein that can mediate both plasmid transfer and the interbacterial transfer of chromosomal genes (i.e., chromosome-mobilizing ability [Cma]) during mating. Here we report the results of in-frame insertional mutagenesis studies aimed at defining regions of Tra required for these functions. While hexameric linker insertions throughout the tra gene affected plasmid and chromosomal gene transfer, insertions in a 200-amino- acid region of the Tra protein that contains presumed nucleotide-binding motifs and that is widely conserved among a functionally diverse family of bacterial and plasmid proteins (K. J. Begg, S. …

Synchrotron X-Ray Microtomography, Electron Probe Microanalysis, And Nmr Of Toluene Waste In Cement, Leslie G. Butler, John W. Owens, Frank K. Cartledge, Richard L. Kurtz, Gary R. Byerly, Andrew J. Wales, Pamela L. Bryant, Earl F. Emery, Betsy Dowd, Xiaogang Xie

Faculty Publications

Synchrotron X-ray microtomography shows vesicular structures for toluene/cement mixtures, prepared with 1.22-3.58 wt % toluene. Three-dimensional imaging of the cured samples shows spherical vesicles, with diameters ranging from 20 to 250/μm; a search with EPMA for vesicles in the range of 1-20/μm proved negative. However, the total vesicle volume, as computed from the microtomography images, accounts for less than 10% of initial toluene. Since the cements were cured in sealed bottles, the larger portion of toluene must be dispersed within the cement matrix. Evidence for toluene in the cement matrix comes from 29Si MAS NMR spectroscopy, which shows a reduction …

Theoretical Prediction Of Nuclear Quadrupole Resonance Spectra Of Aluminum, Bromine And Nitrogen Compounds Via First Principles Calculations, Chris Harwell

LSU Historical Dissertations and Theses

We study the interaction of the electric field gradient (EFG) and the nuclear quadrupole moment of ⁸¹Br,²⁷Al, and ¹⁴N nuclei via ab initio quantum chemistry calculations. The primary goal is to predict the nuclear magnetic resonance (NMR) spectral parameters of interesting materials and assist in interpretation of their spectra. The calculations predict NMR spectral parameters for:

1. ²⁷Al nuclei in andalusite, sillimanite and kyanite - three polymorphs of Al2Si05 - for assigning NMR signals to crystallographic sites, as a zeolite model and studying the effect of structural changes due to temperature (25-1000''C);
2. ¹⁴N nuclei in …

Optical Studies Of The X-Ray Transient Xte J2123-058 - I. Photometry, C. Zurita, J. Casares, T. Shahbaz, P. A. Charles, R. I. Hynes, S. Shugarov, V. Goransky, E. P. Pavlenko, Y. Kuznetsova

Faculty Publications

We present optical photometry of the X-ray transient XTE J2123-058, obtained in 1998 July-October. The light curves are strongly modulated on the 5.95-h orbital period, and exhibit dramatic changes in amplitude and form during the decline. We used synthetic models, which include the effect of partial eclipses and X-ray heating effects, to estimate the system parameters, and we constrain the binary inclination to be i = 73° ± 4. The model is successful in reproducing the light curves at different stages of the decay by requiring the accretion disc to become smaller and thinner by 30 per cent as the …

Holes In A Quantum Spin Liquid, Guangyong Xu, G. Aeppli, M. E. Bisher, C. Broholm, J. F. Ditusa, C. D. Frost, T. Ito, K. Oka, R. L. Paul, H. Takagi, M. M.J. Treacy

Faculty Publications

Magnetic neutron scattering provides evidence for nucleation of antiferromagnetic droplets around impurities in a doped nickel oxide-based quantum magnet. The undoped parent compound contains a spin liquid with a cooperative singlet ground state and a gap in the magnetic excitation spectrum. Calcium doping creates excitations below the gap with an incommensurate structure factor. We show that weakly interacting antiferromagnetic droplets with a central phase shift of π and a size controlled by the correlation length of the quantum liquid can account for the data. The experiment provides a quantitative impression of the magnetic polarization cloud associated with holes in a …

Classification Of The Lie Bialgebra Structures On The Witt And Virasoro Algebras, Siu Hung Ng, Earl J. Taft

Faculty Publications

We prove that all the Lie bialgebra structures on the one sided Witt algebra W1, on the Witt algebra W and on the Virasoro algebra V are triangular coboundary Lie bialgebra structures associated to skew-symmetric solutions r of the classical Yang-Baxter equation of the form r = a ∧ b. In particular, for the one-sided Witt algebra W1 = Der k[t] over an algebraically closed field k of characteristic zero, the Lie bialgebra structures discovered in Michaelis (Adv. Math. 107 (1994) 365-392) and Taft (J. Pure Appl. Algebra 87 (1993) 301-312) are all the Lie bialgebra structures on W1 up …
