Emd: An Ensemble Algorithm For Discovering Regulatory Motifs In Dna Sequences, Jianjun Hu, Yifeng D. Yang, Daisuke Kihara

Department of Biological Sciences Faculty Publications

Background

Understanding gene regulatory networks has become one of the central research problems in bioinformatics. More than thirty algorithms have been proposed to identify DNA regulatory sites during the past thirty years. However, the prediction accuracy of these algorithms is still quite low. Ensemble algorithms have emerged as an effective strategy in bioinformatics for improving the prediction accuracy by exploiting the synergetic prediction capability of multiple algorithms.

Results

We proposed a novel clustering-based ensemble algorithm named EMD for de novo motif discovery by combining multiple predictions from multiple runs of one or more base component algorithms. The ensemble approach is …

Development Of A Fourier Transform Far Infrared (Ftfir) Spectrometer To Characterize Broadband Transmission Properties Of Common Materials In The Terahertz Region, William Paul Ford

Browse all Theses and Dissertations

With sub-millimeter wave or terahertz devices becoming more readily available, there is interest in developing sensors in this region of the spectra. To support this interest, we have developed a Fourier Transform Far InfraRed (FTFIR) spectrometer to characterize broadband transmission and reflectance coefficients of materials. The spectrometer utilizes a broadband blackbody source, a Michelson interferometer, and silicon bolometer. The path difference in the Michelson is obtained using a linear stage and data acquisition and stage control were both implemented in a Labview programming environment. The details of the experimental setup and experimental results are presented in this thesis. The instrument …

Present Status Of Controversies Regarding The Thermal Casimir Force, V. M. Mostepanenko, V. B. Bezerra, R. S. Decca, B. Geyer, E. Fischbach, L. Klimchitskaya, D. E. Krause, D. Lopez, C. Romer

Department of Physics and Astronomy Faculty Publications

It is well known that, beginning in 2000, the behaviour of the thermal correction to the Casimir force between real metals has been hotly debated. As was shown by several research groups, the Lifshitz theory, which provides the theoretical foundation for the calculation of both the van der Waals and Casimir forces, leads to different results depending on the model of metal conductivity used. To resolve these controversies, theoretical considerations based on the principles of thermodynamics and new experimental tests were invoked. We analyse the present status of the problem (in particular, the advantages and disadvantages of the approaches based …

Comparison Of Kinetic Models For Gas Damping Of Moving Microbeams, Alina A. Alexeenko, E Phillip Muntz, Michael A. Gallis, John R. Torczynski

School of Aeronautics and Astronautics Faculty Publications

Numerical investigations of the gas flow structure and the gas-damping force on moving and heated microbeams are carried out using the Navier-Stokes equations with first-order velocity-slip and temperature-jump boundary conditions (the NSSJ method) and two kinetic numerical techniques: the particle-based direct simulation Monte Carlo (DSMC) method, and a deterministic discrete-ordinate solution of the ellipsoidal statistical (ES) kinetic model equation. The gas-damping coefficients on a moving microbeam for quasi-static isothermal conditions are estimated by the three numerical methods for Kn = 0.1-1.0. The NSSJ simulations tend to overestimate the gas-damping coefficient for Knudsen numbers larger than 0.1, whereas the DSMC and …

Epidemiological Models For Mutating Pathogens With Temporary Immunity, Neeta Singh

Electronic Theses and Dissertations

Significant progress has been made in understanding different scenarios for disease transmissions and behavior of epidemics in recent years. A considerable amount of work has been done in modeling the dynamics of diseases by systems of ordinary differential equations. But there are very few mathematical models that deal with the genetic mutations of a pathogen. In-fact, not much has been done to model the dynamics of mutations of pathogen explaining its effort to escape the host's immune defense system after it has infected the host. In this dissertation we develop an SIR model with variable infection age for the transmission …

Experimental Infection Of Fox Squirrels (Sciurus Niger) With West Nile Virus, J. Jeffrey Root, Paul T. Oesterle, Nicole M. Nemeth, Kaci Klenk, Daniel H. Gould, Robert G. Mclean, Larry Clark, Jeffrey S. Hall

United States Department of Agriculture Wildlife Services: Staff Publications

Tree squirrels (Sciurus spp.) have exhibited high seroprevalence rates, suggesting that they are commonly exposed to West Nile virus (WNV). Many characteristics of WNV infections in tree squirrels, such as the durations and levels of viremia, remain unknown. To better understand WNV infections in fox squirrels (S. niger), we subcutaneously inoculated fourteen fox squirrels with WNV. Peak viremias ranged from 10^4.00 plaque-forming units (PFU)/mL of serum on day 2 post-infection (DPI) to 10^4.98 PFU/mL on 3 DPI, although viremias varied between individuals. Oral secretions of some fox squirrels were positive for WNV viral RNA, occasionally …

Determination Of Diphacinone Residues In Hawaiian Invertebrates, Thomas M. Primus, Dennis J. Kohler, John J. Johnston

United States Department of Agriculture Wildlife Services: Staff Publications

A reversed-phase ion-pair liquid chromatogaphic analysis combined with a solid-phase extraction clean-up method is used to assess the quantity of diphacinone residue found in invertebrates. Three invertebrate species are exposed to commercially available diphacinone-fortified bait used for rat control. The invertebrate samples are collected, frozen, and shipped to the laboratory. The samples are homogenized after cryogenic freezing. A portion of the homogenized samples are extracted with acidified chloroform-acetone, followed by cleanup with a silica solid-phase extraction column. Diphacinone is detected by UV absorption at 325 nm after separation by the chromatographic system. The method limit of detection (MLOD) for snail …

Modeling Blackbird Abundance In The Prairie Pothole Region Using A Hierarchical Spatial Model, Greg M. Forcey, George M. Linz, Wayne E. Thogmartin, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

Blackbirds are ubiquitous members of the avian fauna in the Prairie Pothole Region. However, their abundance combined with their food habits make blackbirds significant agricultural pests on sunflower. Cost estimates for blackbird damage to sunflower in the northern Great Plains range from 4-11 million U.S. dollars per year. Because of their economic impact on agriculture, it is imperative to understand the environmental factors that influence blackbird abundance patterns. This study attempts to quantify the effects of landscape-level land use and climate patterns on blackbird abundance in the Prairie Pothole Region of the United States.

Dispersal Of Adult Diatraea Grandiosella (Lepidoptera: Crambidae) And Its Implications For Corn Borer Resistance Management In Bacillus Thuringiensis Maize, Jawwad A. Qureshi, Lawrent L. Buschman, James E. Throne, Sonny B. Ramaswamy

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Dispersal of the southwestern corn borer, Diatraea grandiosella Dyar, was examined by release and recapture of dye-marked adults and by capture of feral adults in and around 50-ha center pivot irrigated fields of Bacillus thuringiensis (Bt) maize. Pheromone and blacklight traps were used to capture the adults. In 1999, 2000, and 2001, a total of 177, 602, and 1,292 marked males, and 87, 231, and 1,045 marked females were released in four irrigated Bt maize fields, respectively. Recapture beyond release point was 2.13, 6.17, 3.16, and 17.91% for males and 0, 0, 2.23, and 4.18% for females in the four …

Tegman V. Accident & Medical Investigations, Inc.: The Re-Modification Of Modified Joint And Several Liability By Judicial Fiat, Victor J. Torres

Seattle University Law Review

This Note explores the Tegman decision in the context of joint and several liability between negligent and intentional actors within Washington State. Part II places Washington tort law into perspective, including the doctrine of joint and several liability, both before and after the Tort Reform Act of 1986. Part III discusses the Tegman decision, methods used in other jurisdictions for dealing with similar situations, and potential solutions to the problems posed by the Tegman holding. Finally, Part IV concludes and urges both the court to reconsider its ruling in Tegman and the legislature to clarify its intent.
