The role of nanotopographical extracellular matrix (ECM) cues in vascular endothelial cell (EC) organization and function is not well-understood, despite the composition of nano- to microscale fibrillar ECMs within blood vessels. Instead, the predominant modulator of EC organization and function is traditionally thought to be hemodynamic shear stress, in which...
The purpose of this study is to explore kernel machine learning methods for species distribution modeling. Previous studies have shown the success of Generalized Boosted Regression Models, however kernel methods have been unexplored for species distribution modeling. Using the eBird dataset, four machine learning methods were tested for accuracy and...
An analysis that accounts for the effect of standard electrostatic discharge (ESD) structures on critical LNA specifications of noise figure, input matching and gain is presented. It is shown that the ESD structures degrade LNA performance particularly for higher frequency applications. Two LNAs, one with ESD protection and one without,...
A study of the effect of catalyst properties on the synthesis of carbon nanotubes (CNTs) is done in this thesis. Three different metal alloy catalysts, Fe/Ti, Ni/Ti, Co/Ti, have been studied. Various atomic concentrations and thicknesses were cosputter deposited on clean Si wafers using AJA Orion 4 RF Magnetron sputter...
Co-opetition, or simultaneous competition and cooperation, in the supply chain management literature has been treated as a dyadic relational phenomenon where the buyer's strategy is considered to be the primary driver. In this paper, we move beyond the dyadic view and propose a theory of co-opetition in supply networks. We...
This issue is packed with information. James Osborne, Enology Extension Specialist, OSU, opens the newsletter with an article about managing Brettanomyces and spoilage in the winery. Patty Skinkis, Viticulture Extension Specialist, OSU, provides an article on the challenge of yield estimation in vineyards. Jay Pscheidt, Extension Plant Pathologist, OSU, provides a timely article on scouting for crown...
Tan spot of wheat is an economically significant disease caused by the fungal pathogen, Pyrenophora tritici-repentis. Certain races of the fungus secrete Ptr ToxA (ToxA), a 13.2 kDa proteinaceous host-selective toxin that is responsible and sufficient to cause disease in susceptible wheat varieties. Disease symptoms develop only when the ToxA...
In Part I, (4S,5R)-4,5-dimethyl-4-phenylcyclohex-2-enone (19a) was prepared in 73% yield with high enantio- and diastereo-selectivity (er > 98:2, dr > 20:1) on a multigram scale by a Yamada-Otani condensation between (E)-pent-3-en-2-one and 2-phenylpropanal catalyzed by a sulfonimide derivative of (S)-proline (18, HuaCat®). Synthetically useful transformations of the cyclohexenone product 19a...
The purposes of this phenomenological inquiry was to examine the challenges faced by administrative leaders of Disabled Student Programs and Services (DSPS) at California community colleges (CCC) from the perspectives of current practitioners. This study was undertaken for the following reasons: (a) the increasing number of students with disabilities accessing...
Growth hormone binding protein (GHBP) may be an important
factor in the regulation of growth as well as an indirect,
less invasive way of predicting the status of growth hormone
receptors. Several factors (age, nutritional status, sex,
and glucocorticoid administration) have been reported to
influence circulating growth hormone (GH) levels,...
