Statistical Implications Of Pooling Rna Samples For Microarray Experiments, Xuejun Peng, Constance L. Wood, Eric M. Blalock, Kuey Chu Chen, Philip W. Landfield, Arnold J. Stromberg
Statistical Implications Of Pooling Rna Samples For Microarray Experiments, Xuejun Peng, Constance L. Wood, Eric M. Blalock, Kuey Chu Chen, Philip W. Landfield, Arnold J. Stromberg
Statistics Faculty Publications
BACKGROUND: Microarray technology has become a very important tool for studying gene expression profiles under various conditions. Biologists often pool RNA samples extracted from different subjects onto a single microarray chip to help defray the cost of microarray experiments as well as to correct for the technical difficulty in getting sufficient RNA from a single subject. However, the statistical, technical and financial implications of pooling have not been explicitly investigated.
RESULTS: Modeling the resulting gene expression from sample pooling as a mixture of individual responses, we derived expressions for the experimental error and provided both upper and lower bounds for …

We report on single-dish monitoring and extremely high angular resolution observations of the flaring H2O megamaser in the Seyfert 2 galaxy Mrk 348. The H2O line is redshifted by ~130 km s-1 with respect to the systemic velocity, is very broad, with an FWHM of 130 km s-1, and has no detectable high-velocity components within 1500 km s-1 on either side of the strong line. Monitoring observations made with the Effelsberg 100 m telescope show that the maser varies significantly on timescales as short as 1 day and that the integrated line …

Assessing The Benefits Of Misting–Cooling Systems For Growing/Finishing Swine As Affected By Environment And Pig Placement Date, Thomas C. Bridges, Larry W. Turner, Richard S. Gates, Douglas G. Overhults
Biosystems and Agricultural Engineering Faculty Publications
The NCPIG swine growth model was used to evaluate swine growth performance for Wilmington, North Carolina; Bardstown and Mayfield, Kentucky; and Oklahoma City, Oklahoma as influenced by the use of a misting–cooling system. Five pig placement dates (Julian days 106, 126, 146, 166, and 186) were evaluated for each location using 22 years of weather data (1978–1999). The use of a misting system, while quite variable, was found to be generally profitable, reducing the length of the time to reach market weight. As the placement date increased, the average return to misting ($/pig/year) decreased from $8.12 to $1.98 for Oklahoma …

The Development Of Relationships Between Constituent Concentrations And Generic Hydrological Variables, Carmen T. Agouridis, Dwayne R. Edwards
The Development Of Relationships Between Constituent Concentrations And Generic Hydrological Variables, Carmen T. Agouridis, Dwayne R. Edwards
Biosystems and Agricultural Engineering Faculty Publications
The collection and analysis of samples from storm events constitutes a large portion of the effort associated with water quality research. Estimating concentrations or loads from these events is often difficult. The equipment necessary to analyze the samples and the required laboratory resources are typically significant expenses incurred by the researcher. One potential method to reduce these costs is through the development of generic relationships between concentrations and easily measured variables such as dimensionless flow rate or time. The benefits recognized from such an effort include a reduction in the number of required samples, resulting in a reduction in cost. …

Physics and Astronomy Faculty Publications
The intensity of the strong N V λ1240 line relative to C IV λ1549 or to He II λ1640 has been proposed as an indicator of the metallicity of quasi-stellar object (QSO) broad emission line regions, allowing abundance measurements in a large number of QSOs out to the highest redshifts. Previously, it had been shown that the (normally) much weaker lines N III] λ1750 and N IV] λ1486 could be used in the same way. The redshift 1.96 QSO 0353-383 has long been known to have N III] and N IV] lines that are far stronger relative to Lyα or …

We show that the mass of ionized gas in the broad-line regions (BLRs) of luminous quasars is at least several hundred M☉, and probably of the order of 103-104 Msolar. BLR mass estimates in several existing textbooks suggest lower values but pertain to much less luminous Seyfert galaxies or include only a small fraction of the ionized/emitting volume of the BLR. The previous estimates also fail to include the large amounts of BLR gas that emit at low efficiency (in a given line) but that must be present based on reverberation and other …

We present Hubble Space Telescope (HST)/STIS long-slit spectroscopy of NGC 1976. Our goal is to measure the intrinsic line ratio [O III] 4364/5008 and thereby evaluate the electron temperature (Te) and the fractional mean-square Te variation (t2A)across the nebula. We also measure the intrinsic line ratio [N II] 5756/6585 in order to estimate Te and t2A in the N+region. The interpretation of the [N II] data is not as clear cut as the [O III] data because of a higher sensitivity to knowledge …
Precision Farming In Central Kentucky: Evaluating Public And Private Sector Influence On The Adoption Decision, Rod Grusy
Soil Science News and Views
The Cooperative Extension Service is challenged to assess the needs of customers who are unable or unwilling to try new production techniques with the potential to increase profitability. Precision Farming (PF) is a production technique that has the goal of maximizing economic potential by using technology that recognizes variability within fields. Ample research from the last decade shows that precision technologies hold promise for enhanced agricultural profitability. A study conducted in three Central Kentucky counties in 2001 shows that farmers obtain information for decision-making related to PF technologies from their local fertilizer dealer and the Cooperative Extension Service but are …
Value Of Nutrients In Poultry Litter When Applied In The Fall, Monroe Rasnake, George Kelley
Value Of Nutrients In Poultry Litter When Applied In The Fall, Monroe Rasnake, George Kelley
Soil Science News and Views
The value of nutrients in poultry litter depends not only on how much nitrogen (N), phosphorus (P) and potassium (K) it contains, but also on how it is handled and applied. The following table compares the value of 19 poultry litter samples from Hopkins County analyzed for N, P & K and the litter then spread in the fall. The samples include pullet, breeder and broiler manures, with storage times up to one year. Nutrient values were based on a comparison with urea (46-0-0) at $199/ton, triple super phosphate (0-46-0) at $215/ton and muriate of potash (0-0-60) at $165/ton.
Fixed Points Of Holomorphic Mappings For Domains In Banach Spaces, Lawrence A. Harris
Fixed Points Of Holomorphic Mappings For Domains In Banach Spaces, Lawrence A. Harris
Mathematics Faculty Publications
We discuss the Earle-Hamilton fixed-point theorem and show how it can be applied when restrictions are known on the numerical range of a holomorphic function. In particular, we extend the Earle-Hamilton theorem to holomorphic functions with numerical range having real part strictly less than 1. We also extend the Lumer-Phillips theorem estimating resolvents to dissipative holomorphic functions.
