Making Classical And Quantum Canonical General Relativity Computable Through A Power Series Expansion In The Inverse Cosmological Constant, Rodolfo Gambini, Jorge Pullin Dec 2000

Making Classical And Quantum Canonical General Relativity Computable Through A Power Series Expansion In The Inverse Cosmological Constant, Rodolfo Gambini, Jorge Pullin

Faculty Publications

Casting ordinary general relativity as a perturbative theory in Λ-1 and starting with background theory in which Λ → ∞ allows one to explicitly compute nondegenerate physical quantum states and observables. The technique is applicable in the theory in general and also in mini-super-space models. In the general theory, the calculations are well defined and tractable, but quite involved. This opens up a program for the quantization of the gravitational field that is well defined computationally and allows contact with the physical observables of the theory, a key ingredient in the road to finding a theory with a semiclassical regime …

Soft-X-Ray Fluorescence Study Of The Quasi-One-Dimensional Heisenberg Antiferromagnet Tetraphenylverdazyl, E. Z. Kurmaev, V. R. Galakhov, S. Shimada, T. Otsuka, K. Endo, S. Stadler, D. L. Ederer, A. Moewes, H. Schuerman, M. Neumann, S. Tomiyoshi, N. Azuma, M. Iwami Dec 2000

Soft-X-Ray Fluorescence Study Of The Quasi-One-Dimensional Heisenberg Antiferromagnet Tetraphenylverdazyl, E. Z. Kurmaev, V. R. Galakhov, S. Shimada, T. Otsuka, K. Endo, S. Stadler, D. L. Ederer, A. Moewes, H. Schuerman, M. Neumann, S. Tomiyoshi, N. Azuma, M. Iwami

Faculty Publications

Soft-x-ray fluorescence measurements have been performed on a single crystal of the organic antiferromagnet 2,4,6-triphenylverdazyl. Resonant and nonresonant C Kα and N Kα (2p → 1s transition) x-ray emission spectra (XES) were measured and compared with x-ray photoelectron valence band spectra and deMon density-functional theory calculations. It is shown that intramolecular interactions are much stronger than intermolecular ones and give the main contribution to the formation of C 2p density of states. We present evidence of a delocalization of unpaired N 2p electrons over the verdazyl ring. The excitation energy dependence of C Kα and N Kα XES observed below …

High-Quality P-N Junctions With Quaternary Alingan/Ingan Quantum Wells, A. Chitnis, A. Kumar, M. Shatalov, V. Adivarahan, A. Lunev, J. W. Yang, Grigory Simin, M. Asif Khan, R. Gaska, M. Shur Dec 2000

High-Quality P-N Junctions With Quaternary Alingan/Ingan Quantum Wells, A. Chitnis, A. Kumar, M. Shatalov, V. Adivarahan, A. Lunev, J. W. Yang, Grigory Simin, M. Asif Khan, R. Gaska, M. Shur

Faculty Publications

We report on quaternary AlInGaN/InGaN multiple quantum well(MQW)light emitting diode structures grown on sapphire substrates. The structures demonstrate high quality of the p–njunctions with quaternary MQW. At low forward bias (below 2 V), the temperature dependent of current–voltage characteristics are exponential with the ideality factor of 2.28, which is in a good agreement with the model of the injected carrier recombination in the space charge region. This ideality factor value is approximately three times lower than for conventional GaN/InGaN light emitting diodes(LEDs). The obtained data indicate the recombination in p–njunction space charge region to be responsible for a current transport …

Carbon Monoxide Production Is Not Enhanced By Nitrogenase Activity, P. Milligan, G. M. King Dec 2000

Carbon Monoxide Production Is Not Enhanced By Nitrogenase Activity, P. Milligan, G. M. King

Faculty Publications

A diverse group of nitrogen-fixing bacteria and two heme degraders were grown with and without fixed nitrogen sources under oxic and suboxic conditions, with and without addition of heme-containing compounds. Several of the strains produced carbon monoxide (CO) under one or more of these conditions, but nitrogenase activity did not stimulate rates of production relative to controls. Although nitrogenase can reduce CO2 to CO in vitro in the absence of N2, this process likely contributes minimally to CO production in soils under in situ conditions. In contrast, myoglobin or hematin addition under oxic conditions significantly stimulated CO production by the …

Faculty Publications

The unoccupied electronic structure for the Sr14Cu24O41 family of two-leg ladder compounds was investigated for different partial substitutions of Sr2+ by Ca2+, leaving the nominal hole count constant, and by Y3+ or La3+, reducing the nominal hole count from its full value of 6 per formula unit. Using polarization-dependent x-ray absorption spectroscopy on single crystals, hole states on both the chain and ladder sites could be studied. While for intermediate hole counts all holes reside on O sites of the chains, a partial hole occupation on the ladder sites in orbitals oriented along the legs is observed for the fully …

Land Use Impacts On Atmospheric Carbon Monoxide Consumption By Soils, G. M. King Dec 2000

Land Use Impacts On Atmospheric Carbon Monoxide Consumption By Soils, G. M. King

Faculty Publications

Seasonal analyses of in situ CO fluxes from forested and agricultural soils in Maine and Georgia, and more limited comparisons in Hawai'i indicated that agricultural land use consistently enhanced CO consumption. Soils at an agricultural site in Maine consumed approximately 1.9 g CO m-2 yr-1 while uptake in a nearby mixed forest was about 70% lower, 0.6 g CO m-2 yr-1. A similar trend was observed for sites in Georgia, where annual uptake by agricultural sites was approximately 1.0 g CO m-2 while net emission (about -0.5 g CO m-2) was observed for neighboring pine stands. Net CO fluxes in …

Minimal And Contributing Sequence Determinants Of The Cis-Acting Locus Of Transfer (Clt) Of Streptomycete Plasmid Pij101 Occur Within An Intrinsically Curved Plasmid Region, M. J. Ducote, S. Prakash, G. S. Pettis Dec 2000

Minimal And Contributing Sequence Determinants Of The Cis-Acting Locus Of Transfer (Clt) Of Streptomycete Plasmid Pij101 Occur Within An Intrinsically Curved Plasmid Region, M. J. Ducote, S. Prakash, G. S. Pettis

Faculty Publications

Efficient interbacterial transfer of streptomycete plasmid pIJ101 requires the pIJ101 tra gene, as well as a cis-acting plasmid function known as clt. Here we show that the minimal pIJ101 clt locus consists of a sequence no greater than 54 bp in size that includes essential inverted-repeat and direct-repeat sequences and is located in close proximity to the 3′ end of the korB regulatory gene. Evidence that sequences extending beyond the minimal locus and into the korB open reading frame influence clt transfer function and demonstration that clt-korB sequences are intrinsically curved raise the possibility that higher-order structuring of DNA and …

A Simple Surface Temperature Assimilation Scheme For Use In Land Surface Models, Venkataraman Lakshmi Dec 2000

A Simple Surface Temperature Assimilation Scheme For Use In Land Surface Models, Venkataraman Lakshmi

Faculty Publications

This paper examines the utilization of surface temperature as a variable which can be assimilated in off-line land surface hydrological models. The connection between the surface temperature and evapotranspiration is utilized in making adjustments to the model-computed surface soil moisture. This adjustment is a function of the difference between the model-computed and the observed surface temperature. Comparisons between the model-computed and satellite-observed surface temperatures have been carried out. The assimilation of surface temperature is carried out twice a day (corresponding to the A.M. and P.M. overpass of the NOAA 10) over the Red-Arkansas basin in the southwestern United States (31°50′N-36°N, …

Simplified Calculation Of The Stability Matrix For Semiclassical Propagation, Sophya Garashchuk, John C. Light Dec 2000

Simplified Calculation Of The Stability Matrix For Semiclassical Propagation, Sophya Garashchuk, John C. Light

Faculty Publications

We present a simple method of calculation of the stability (monodromy) matrix that enters the widely used semiclassical propagator of Herman and Kluk and almost all other semiclassical propagators. The method is based on the unitarity of classical propagation and does not involve any approximations. The number of auxiliary differential equations per trajectory scales linearly rather than quadratically with the system size. Just the first derivatives of the potential surface are needed. The method is illustrated on the collinear H[sub 3] system.

Functional Projections Of Predicates: Experimental Evidence From Coordinate Structure Processing, Stanley William Dubinsky, Marie Egan, A. Rene Schumauder, Matthew J. Traxler Dec 2000

Functional Projections Of Predicates: Experimental Evidence From Coordinate Structure Processing, Stanley William Dubinsky, Marie Egan, A. Rene Schumauder, Matthew J. Traxler

Faculty Publications

This paper reports the results of six experiments involving an on-line self-paced reading task that examine the processing of coordinate small clause predicate phrases versus coordinated arguments NPs. The results have particular significance for the analysis of small clause complement constructions, and support accounts wherein the small clause complement has an Agr projection associated with it. An adequate explanation of the processing of small clause coordination is shown to motivate a new parsing principle, Coordination Feature-matching, which accounts for the longer reading times observed for the coordination of predicates in small clause complements.

Effect Of Gate Leakage Current On Noise Properties Of Algan/Gan Field Effect Transistors, S. L. Rumyantsev, N. Pala, M. S. Shur, R. Gaska, M. E. Levinshtein, M. Asif Khan, Grigory Simin, X. Hu, J. Yang

Faculty Publications

The effect of the gate leakage current fluctuations on noiseproperties of AlGaN/GaN heterostructurefield effect transistors(HFETs) has been studied in conventional HFET structures and in AlGaN/GaN metal-oxide-semiconductorheterostructurefield effect transistors (MOS-HFETs). The comparison of the noiseproperties of conventional AlGaN/GaN HFETs and AlGaN/GaN MOS-HFETs fabricated on the same wafer, allowed us to estimate the contribution of the gate currentnoise to the HFET’s output noise. The effect of the gate current fluctuations on output noiseproperties of HFETs depends on the level of noise in the AlGaN/GaN HFETs. For the transistors with a relatively high magnitude of the Hooge parameter α∼10−3, even a …

Proteolytic Enzymes In The Marine Bacterium Pseudoalteromonas Atlantica: Post-Secretional Activation And Effects Of Environmental Conditions, Monica Hoffman, Alan W. Decho Dec 2000

Proteolytic Enzymes In The Marine Bacterium Pseudoalteromonas Atlantica: Post-Secretional Activation And Effects Of Environmental Conditions, Monica Hoffman, Alan W. Decho

Faculty Publications

Production and activities of cellular and extracellular proteolytic enzymes associated with the marine bacterium Pseudoalteromonas atlantica were examined in response to physiological state and changing environmental variables under laboratory conditions. Enzymes evidenced by zymography were metalloproteases, as defined by substrate preference and susceptibility to inhibitors (EDTA and 1, 10-phenanthroline). Distinct bands (i.e. molecular-weight [MW] size classes) of enzymes were isolated from within cellular and extracellular compartments. Susceptibility of extracellular enzymes to environmental stressors was related, in part, to the MW size classes of the enzymes. While all bands of enzymes showed some degree of inhibition when pH was decreased, the …

Gender Differences In Sexual Behaviors And Factors Associated With Nonuse Of Condoms Among Homeless And Runaway Youths, Duncan A. Mackeller, Linda A. Valleroy, John P. Hoffmann, Donna Glebatis, Marlene Lalota, William Mcfarland, Johnny Westerholm, Robert S. Janssen Dec 2000

Gender Differences In Sexual Behaviors And Factors Associated With Nonuse Of Condoms Among Homeless And Runaway Youths, Duncan A. Mackeller, Linda A. Valleroy, John P. Hoffmann, Donna Glebatis, Marlene Lalota, William Mcfarland, Johnny Westerholm, Robert S. Janssen

Faculty Publications

Few studies have examined gender-specific factors associated with the nonuse of condoms among homeless and runaway youths (HRYs)–a population at high risk for HIV infection. In this article, we evaluate these factors and explore gender differences in background experiences, psychosocial functioning, and risk behaviors among HRYs from four U.S. metropolitan areas. Of 879 sexually active HRYs sampled, approximately 70% reported unprotected sexual intercourse during a 6-month period, and nearly a quarter reported never using condoms in the same period. Among males and females, having only one sex partner in the previous 6 months had the strongest association with nonuse of …

Finite-Aperture Wire Grid Polarizers, Michael A. Jensen, Gregory P. Nordin Dec 2000

Finite-Aperture Wire Grid Polarizers, Michael A. Jensen, Gregory P. Nordin

Faculty Publications

The transmission characteristics of wire grid polarizers fabricated in finite apertures are investigated by using a three-dimensional finite-difference time-domain formulation. Specifically, the optical transmissivity and extinction ratio are characterized for a wide variety of geometrical parameters including aperture size in both dimensions, conducting wire fill factor, and polarizer thickness. A dispersive material model is used to investigate the performance of polarizers fabricated by using realistic metals at infrared wavelengths. The results indicate that the aperture dimension significantly impacts the polarizer transmission behavior and that the extinction of the unwanted polarization is often limited by depolarizing scattering that is due to …

Direct Generation Of Optical Diffractive Elements In Perfluorocyclobutane (Pfcb) Polymers By Soft Lithography, Gregory P. Nordin, J. Ballato, P. C. Deguzman, S. Foulger, H. Shah, D. Smith

Faculty Publications

Optically diffractive line gratings with 0.58- m feature sizes have been generated in 100- m perfluorocyclobutane (PFCB) polymer films by direct micromolding using only a silicon master. Strong reflectivities from the green to red portions of the visible spectrum, depending on incident beam angle, were observed with 3 dB bandwidths of approximately 30 nm. This negative mold-free technique permits, for the first time to our knowledge, feature reproduction at submicrometer size scales, eliminates several steps from conventional soft lithographic methods, and marks itself as a practical means for rapidly generating planar photonic structures that operate spectrally in the visible and …

Interactions Of Tillage And Soil Depth On Fluometuron Degradation In A Dundee Silt Loam Soil, R. M. Zablotowicz, M. A. Locke, L. A. Gaston, C. T. Bryson Nov 2000

Interactions Of Tillage And Soil Depth On Fluometuron Degradation In A Dundee Silt Loam Soil, R. M. Zablotowicz, M. A. Locke, L. A. Gaston, C. T. Bryson

Faculty Publications

Fluometuron (N,N-dimethyl-N'-[3-(trifluoromethyl)phenyl]urea) is the most widely used soil applied herbicide in cotton (Gossypium hirsutum) production in the Southeastern United States. Thus, there is a need to understand the persistence of this herbicide under various crop management systems in regards to both herbicide efficiency and environmental fate. The effects of long-term no-tillage practices on fluometuron degradation were studied in a Dundee silt loam under laboratory conditions. Soil was collected at four depths (0-2, 2-5, 5-10, and 10-25 cm) from field plots following 11 years of continuous no-tillage (NT) or conventional tillage (CT). Organic carbon content, microbial biomass, and fluorescein diacetate (FDA)-hydrolytic …

We investigate the interfacial electrochemical properties of an aqueous electrolyte solution with discrete water molecules in slab geometry between charged atomistic electrodes. Long-range intermolecular Coulombic interactions are calculated using the particle particle particle mesh method with a modification to account for the slab geometry. Density distribution profiles and potential drops across the double layer are given for 0, 0.25, and 1 M aqueous electrolyte solutions each electrode surface charges. Results are compared qualitatively with experimental x-ray scattering findings, other computer simulation results, and traditional electrochemistry theory. The interfacial fluid structure characteristics are generally in good qualitative agreement with the conclusions …

Kinetic Characterization Of His-Tagged Cp47 Photosystem Ii In Synechocystis Sp. Pcc6803, Zhao Liang Li, Terry M. Bricker, Robert Burnap

Faculty Publications

Recently, construction of strains of Synechocystis sp. PCC6803 having a His6 extension (His-tag) of the carboxyl terminus of the CP47 protein has been reported (T.M. Bricker et al, Biochim. Biophys. Acta 1409 (1998) 50; M.J. Reifler et al., in: Garab, Pusztai (Eds.) Proc. XIth International Congress on Photosynthesis, 1998). While these initial reports suggest a minimal impact of the His-tag upon Photosystem (PS) II function, a more thorough analysis of the kinetic properties of the modified complex is essential. This communication reports on a more detailed kinetic analysis to assess possible perturbations of PS II due to the genetic addition …
