Evidence For An Antagonistic Relationship Between The Boundary Element-Associated Factor Beaf And The Transcription Factor Dref, Craig M. Hart, Olivier Cuvier, Ulrich K. Laemmli Nov 1999

Evidence For An Antagonistic Relationship Between The Boundary Element-Associated Factor Beaf And The Transcription Factor Dref, Craig M. Hart, Olivier Cuvier, Ulrich K. Laemmli

Faculty Publications

Boundary elements interfere with communication between enhancers and promoters, but only when interposed. Understanding this activity will require identifying the proteins involved. The boundary element-associated factor BEAF is one protein that is implicated in boundary element function. Three genomic fragments (scs', BE76 and BE28) containing BEAF binding sites function as boundary elements in transgenic Drosophila, suggesting that this is an intrinsic property of the numerous genomic regions to which BEAF binds. To characterize additional proteins that interact with boundary elements, we have isolated a protein that binds to two of these boundary elements (BE76 and BE28) and have identified it …


Selective Excitation And Thermal Quenching Of The Yellow Luminescence Of Gan, John S. Colton, P. Y. Yu, K. L. Teo, E. R. Weber, P. Perlin, I. Grzegory, K. Uchida Nov 1999

Selective Excitation And Thermal Quenching Of The Yellow Luminescence Of Gan, John S. Colton, P. Y. Yu, K. L. Teo, E. R. Weber, P. Perlin, I. Grzegory, K. Uchida

Faculty Publications

We report the observation of narrower structures in the yellow luminescence of bulk and thin-film n-type GaN, using the technique of selective excitation. These fine structures exhibit thermal quenching associated with an activated behavior. We attribute these fine structures to phonons and electronic excitations of a shallow donor-deep acceptor complex, and determine its activation energy for delocalization. Our results suggest that in addition to distant donor-acceptor pairs, the yellow luminescence can also involve emission complexes of shallow donors and deep acceptors.

Low-Frequency Noise In N-Gan With High Electron Mobility, M. E. Levinshtein, S. L. Rumyantsev, D. C. Look, R. J. Molnar, M. Asif Khan, Grigory Simin, V. Adivarahan, M. S. Shur Nov 1999

Low-Frequency Noise In N-Gan With High Electron Mobility, M. E. Levinshtein, S. L. Rumyantsev, D. C. Look, R. J. Molnar, M. Asif Khan, Grigory Simin, V. Adivarahan, M. S. Shur

Faculty Publications

We report on the results of measurements of low frequency noise in n-type gallium nitride (GaN) grown on sapphire with 300 K electron mobility of 790 cm2/V s. The noise spectra have the form of 1/f noise with a Hooge parameter α of approximately 5×10−2. This value of α is two orders of magnitude smaller than that observed before in n-GaN. The obtained results show that the level of flicker noise in GaN, just like that in GaAs and Si, strongly depends on the structural perfection of the material (the amplitude of the 1/f …


Accuracy Of Scatterometer-Derived Winds Using The Cramer-Rao Bound, David G. Long, Travis E. Oliphant Nov 1999

Accuracy Of Scatterometer-Derived Winds Using The Cramer-Rao Bound, David G. Long, Travis E. Oliphant

Faculty Publications

A wind scatterometer makes measurements of the normalized radar-backscatter coefficient O of the ocean surface. To retrieve the wind, a geophysical model function (GMF), which relates O to the near-surface wind, is used. The wind vector can be estimated using maximum-likelihood techniques from several O measurements made at different azimuth angles. The probability density of the measured O is assumed to be Gaussian with a variance that depends on the true O and therefore, depends on the wind through the GMF. With this model for wind estimation, the Cramer-Rao (C-R) bound is derived for wind estimation, and its implications for …


Synthesis And Unusual Properties Of The First 2,3,7,8,12,13,17,18-Octabromo-5,10,15,20-Tetraalkylporphyrin, Nora Y. Nelson, Craig J. Medforth, Daniel J. Nurco, Song Ling Jia, John A. Shelnutt, Kevin M. Smith Oct 1999

Combining Cross-Validation And Confidence To Measure Fitness, Tony R. Martinez, D. Randall Wilson Jul 1999

Combining Cross-Validation And Confidence To Measure Fitness, Tony R. Martinez, D. Randall Wilson

Faculty Publications

Neural network and machine learning algorithms often have parameters that must be tuned for good performance on a particular task. Leave-one-out cross-validation (LCV) accuracy is often used to measure the fitness of a set of parameter values. However, small changes in parameters often have no effect on LCV accuracy. Many learning algorithms can measure the confidence of a classification decision, but often confidence alone is an inappropriate measure of fitness. This paper proposes a combined measure of Cross- Validation and Confidence (CVC) for obtaining a continuous measure of fitness for sets of parameters in learning algorithms. This paper also proposes …


Major Step Forward: Proposed Uniform Mediation Act Goes Public For Comments, Richard C. Reuben, Nancy H. Rogers Jul 1999

Major Step Forward: Proposed Uniform Mediation Act Goes Public For Comments, Richard C. Reuben, Nancy H. Rogers

Faculty Publications

The move toward a simplified and uniform law for mediation takes an important step forward this summer, with the release of the first integrated draft of the proposed Uniform Mediation Act. The act is being drafted by cooperating committees of the American Bar Association Section of Dispute Resolution and the National Conference of Commissioners on Uniform State Laws. If enacted and adopted uniformly, it would replace the hundreds of pages of complex and often conflicting statutes across the country with a few short pages of simple, accessible, and helpful rules.


Blue Crab Larval Dispersion And Retention In The Mississippi Bight, Donald R. Johnson, Harriet M. Perry Jul 1999

Blue Crab Larval Dispersion And Retention In The Mississippi Bight, Donald R. Johnson, Harriet M. Perry

Faculty Publications

A conceptual hypothesis relating physical forcing to dispersion and retention was developed for blue crab larvae within the Mississippi Eight. The spawning period for blue crabs in the northern Gulf of Mexico is protracted. Hatching of eggs occurs near the barrier islands and mouths of coastal bays from March through October. Larvae are released on ebbing tides and spend the next 30 to 50 d offshore where they develop through seven zoeal stages before undergoing metamorphosis to megalopae. Duration of the megalopal stage is variable but generally persists from 6 to 20 d. Blue crabs recruit to Gulf estuaries as …

Faculty Publications

We report measurements of the mass density, ΩM, and cosmological-constant energy density, ΩΛ of the universe based on the analysis of 42 type Ia supernovae discovered by the Supernova Cosmology Project. The magnitude-redshift data for these supernovae, at redshifts between 0.18 and 0.83, are fitted jointly with a set of supernovae from the Calán/Tololo Supernova Survey, at redshifts below 0.1, to yield values for the cosmological parameters. All supernova peak magnitudes are standardized using a SN Ia light-curve width-luminosity relation. The measurement yields a joint probability distribution of the cosmological parameters that is approximated by the relation 0.8ΩM - 0.6ΩΛ …

The biological role(s) proposed for UCP3 in energy homeostasis have been based primarily upon amino acid sequence homology to UCP1. Spontaneous mutations of UCP3 have been described in humans, but not in rodents. The functional consequences—or lack thereof—of these mutations in humans will be of great importance in elucidating the biology of this protein. The results of two such studies are summarized here. © 1999 Stockton Press. All rights reserved.

Online Auctions, Michael N. Huhns, José M. Vidal May 1999

Online Auctions, Michael N. Huhns, José M. Vidal

Faculty Publications

Auctions on the Internet can involve not only consumers, but also businesses. They can form dynamically and enable the exchange of goods much as stock exchanges manage the buying and selling of securities. But because auctions have a wide scope and a short lifetime, the opportunistic behavior needed for successful interaction requires agents to both participate in and manage auctions. The article focuses on the use of software agents in such Internet based auctions

Stratified Volume Diffractive Optical Elements As High Efficiency Gratings, Gregory P. Nordin, D. M. Chambers May 1999

Stratified Volume Diffractive Optical Elements As High Efficiency Gratings, Gregory P. Nordin, D. M. Chambers

Faculty Publications

We propose stratified volume diffractive optical elements as a new type of diffractive optical element that is capable of functioning as a high-efficiency grating in applications with requirements not suited to traditional holographic or diffractive optical techniques. In this approach, diffractive optical fabrication methods are used to construct an optical structure that emulates volume grating behavior. We discuss the diffraction properties of stratified volume diffractive optical elements and compare them with those used previously in both volume holographic optical elements and stratified volume holographic optical elements. A systematic design process is then presented for deriving structure parameters. We illustrate this …

First Observations Of An R Coronae Borealis Star With The Space Telescope Imaging Spectrograph: Ry Sagittarii Near Maximum Light, Geoffrey C. Clayton, T. R. Ayres, Warrick A. Lawson, John S. Drilling, P. Woitke, Martin Asplund

Faculty Publications

We describe the far-UV (1140-1740 Å) spectrum of the hydrogen-deficient R Coronae Borealis (RCB) star RY Sgr, obtained near maximum light (pulsational phase ≯0.1) by the Space Telescope Imaging Spectrograph (STIS) on Hubble Space Telescope. The far-UV spectrum shows a photospheric continuum rising steeply toward longer wavelengths and two prominent emission features at the shorter wavelengths: C II λ1335 and Cl I λ1351 (the latter is radiatively fluoresced by the 10 times stronger C II multiplet). We also find evidence for CO A-X 4th-positive system absorption band heads and possible weak CO fluorescent emissions pumped by C II λ1335, but …


Portfolio Assessment In Aerodynamics, Nikos J. Mourtos Apr 1999

Portfolio Assessment In Aerodynamics, Nikos J. Mourtos

Faculty Publications

A new way of assessing student learning in an aerodynamics course through the use of portfolios is presented. The approach is portable to any engineering course, with a few modifications depending on content. The main idea is to allow students more responsibility for their own learning. Instead of having everyone in the class perform identical activities (homework, experiments, projects, tests, etc.), a cadre of assignments is made available to them. Students choose and perform (within reason) the ones that suit them better in terms of their own strengths and learning styles. The ultimate goal is for each student to demonstrate …
