Minque: An R Package For Analyzing Various Linear Mixed Models, Jixiang Wu

SDSU Data Science Symposium

Linear mixed model (LMM) approaches offer much more flexibility comparing ANOVA (analysis of variance) based methods. There are three commonly used LMM approaches: maximum likelihood, restricted maximum likelihood, and minimum norm quadratic unbiased estimation. These three approaches, however, sometimes could also lead low testing power compared to ANOVA methods. Integration of resampling techniques like jackknife could help improve testing power based on both our simulation studies. In this presentation, I will introduce a R package, minque, which integrates LMM approaches and resampling techniques and demonstrate the use of this packages in various linear mixed model analyses.

The Influence Of Preovulatory Estradiol On Uterine Transcriptomics And Proteomics Around Maternal Recognition Of Pregnancy In Beef Cattle, Emmalee J. Northrop

Electronic Theses and Dissertations

Preovulatory estradiol has been reported to play a crucial role in pregnancy establishment and maintenance, but the mechanism by which estradiol exerts its effects has not been well characterized. Specifically, the interactions between the maternal uterine environment and the developing conceptus can greatly impact pregnancy success or loss. The objective of this dissertation is to determine the effects of preovulatory estradiol exposure on uterine and trophectoderm transcriptomes, and uterine luminal fluid (ULF) protein composition. Beef cows/heifers were synchronized, artificially inseminated (d 0), and grouped into either high (highE2) or low (lowE2) preovulatory estradiol. Uteri were flushed to collect d16 conceptuses …

Crop Residue Management Challenges: A Special Issue Overview, David Clay, Ronald Alverson, Jane M.F. Johnson, Douglas L. Karlen, Sharon Clay, Michael Q. Wang, Stephanie A. Bruggeman, Shaina Westhoff

Agronomy, Horticulture and Plant Science Faculty Publications

The amount of crop residues that can be sustainability removed is highly variable and is a function of many factors including the soil, climatic, and plant characteristics. For example, leaving an insufficient amount of crop residue on the soil surface can be detrimental for soil quality, result in loss of soil organic matter (SOM), and increase soil erosion, whereas leaving excessive amounts can impair soil-seed contact, immobilize N, and/or keep soils cool and wet. This special issue evolved as an outcome of, “Crop Residues for Advanced Biofuels: Effects on Soil Carbon” workshop held in Sacramento, CA, in 2017. The goal …

The Midwest wine industry has shown a marked increase in growers, hectares planted, wineries, and wine production. This growth coincides with the release of cold-hardy cultivars such as Brianna and Frontenac gris, in 2001 and 2003, respectively. These white grape varieties account for one-third of the total area grown in the state of Iowa. It is generally accepted that the wine aroma profile plays a crucial role in developing a local, sustainable brand. However, the identity of Brianna/Frontenac Gris-based wine aromas and their link to the grape berry chemistry at harvest is unknown. This study aims to preliminarily characterize key …

Biogenic Volatiles Emitted From Four Cold-Hardy Grape Cultivars During Ripening, Somchai Rice, Devin L. Mauer, Anne Fennell, Murlidhar Dharmadhikari, Jacek A. Koziel

Agronomy, Horticulture and Plant Science Faculty Publications

In this research dataset, we summarize for the first time volatile organic compounds (VOCs) emitted in vivo from ripening wine grapes. We studied four cold-hardy cultivars grown in the Midwestern U.S.: St. Croix, Frontenac, Marquette, and La Crescent. These cultivars have gained popularity among local growers and winemakers, but still very little is known about their performance compared with long-established V. vinifera grapes. Volatiles were collected using two novel approaches: biogenic emissions from grape clusters on a vine and single grape berries. A third approach was headspace collection of volatiles from crushed grapes. Solid-phase microextraction (SPME) was used to collect …
