Mechanisms Of Reduced Vascular Tone Following Arteriogenesis Induced By Femoral Artery Ligation, Christopher Hatch

Biomedical Engineering

The presence of a developed, native collateral network can decrease the severity of ischemic injury proceeding arterial occlusion. The collateral network must under arteriogenesis to enlarge and increase blood flow to the ischemic region. Although there has been tremendous effort attempting to understand the mechanisms of arteriogenesis, no therapies have been successful in improving patient outcome. To better understand the mechanisms involved in arteriogenesis, the effect of nitric oxide production, myogenic tone, and a-adrenergic receptors were evaluated as these have been identified as playing an important role in vascular injury. Arteriogenesis was induced by ligating the femoral artery between the …

Proteomic Changes Across A Natural Temperature Gradient In A Marine Gastropod, M Christina Vasquez, Marilla R. Lippert, Crow White, Ryan K. Walter, Lars Tomanek

Physics

Responses of marine ectotherms to variable environmental temperature often entails maintenance of cellular homeostasis and physiological function through temperature compensation and physiological changes. We investigated the physiological response to thermal stress by examining proteomic changes in the marine kelp forest gastropod and emerging fisheries species Kellet's whelk (Kelletia kelletii) across a naturally-existing thermal gradient that ranges from a warmer-water site inside the species' native range and extends to the northern, cold-water edge of the range. We hypothesized that abundance of cellular stress response and energy metabolism proteins would increase with decreasing temperature in support of cold-compensation. Our exploratory …

Infestation Intensities, Attachment Patterns, And The Effect On Host Contest Behavior Of The Tick Ixodes Pacificus On The Lizard Sceloporus Occidentalis, Dylan M. Lanser

Master's Theses

Parasites often have profound effects on the survival and evolution of their hosts, and hence on the structure and health of entire ecosystems. Yet basic questions, such as the degree of virulence of a given parasite on its host, and factors influencing which hosts in a population are at the greatest risk of infection, are vexingly difficult to resolve. The western blacklegged tick-western fence lizard (Ixodes pacificus-Sceloporus occidentalis) system is important, primarily because I. pacificus, a vector of the Lyme disease spirochete Borrelia burgdorferi, is dependent on S. occidentalis for blood meals in its subadult stages, …

Torture And The Corrida, Andrew Brei

Between the Species

In recent years the debate over the moral status of bullfighting has been focused on whether or not it should be characterized as a form of torture. Francis Wolff has argued that it should not be, and Gabriel Andrade has claimed that it should be. But in my view neither author adequately defines bullfighting or torture. In this essay I have three goals. The first is to provide an adequate account of bullfighting, including its structure and meaning. The second is to define the necessary conditions for torture. And the third is to show that bullfighting meets those conditions. Thus, …

Review Of The Oxford Handbook Of Food Ethics, Josh Milburn

Between the Species

The Oxford Handbook of Food Ethics, edited by Anne Barnhill, Mark Budolfson, and Tyler Doggett, contains 35 chapters over 8 sections. Many of these chapters are directly relevant to animal ethicists. Even many of those that do not initially appear to be, however, should be of interest. I thoroughly recommend The Oxford Handbook of Food Ethics to all animal ethicists interested in addressing food-related questions in their research or teaching.

Beaver (Castor Canadensis) Of The Salinas River: A Human Dimensions-Inclusive Overview For Assessing Landscape-Scale Beaver-Assisted Restoration Opportunities, Stuart Christian Suplick

Natural Resources Management and Environmental Sciences

Across the western United States, researchers are increasingly working with beaver (Castor canadensis) for process-based stream and watershed restoration. One recently-developed geographic information system-based tool, the Beaver Restoration Assessment Tool (BRAT), analyzes opportunities for beaver-assisted restoration (BAR) at a landscape-scale. However, this tool benefits significantly from human dimensions-inclusive, basin-centralized beaver knowledge for proper interpretation. Unfortunately, this information is scattered or absent in most semi-arid and arid southern California basins. This study thus sought to gather and produce this information through an explorative, benefits-maximizing approach to landscape-scale BAR opportunities assessment in one of these basins, the Salinas River. 49.2 …

The Five Tribes Of Machine-Learning: A Brief Overview, Jens G. Pohl

Architecture

This paper reviews recent advances in automated computer-based learning capabilities. It briefly describes and examines the strengths and weaknesses of the five principal algorithmic approaches to machine-learning, namely: connectionism; evolutionism; Bayesianism; analogism; and, symbolism. While each of these approaches can demonstrate some degree of learning, a learning capability that is comparable with human learning is still in its infancy and will likely require the combination of multiple algorithmic approaches. However, the current state reached in machine-learning suggests that Artificial General Intelligence and even Artificial Superintelligence may indeed be eventually feasible.

Integrated Aeration For Enhanced Nitrogen Conversion And Removal And The Effect Of Sampling Frequency On Productivity Estimates In Algae-Based Wastewater Treatment Systems, Lauren Parker

Master's Theses

Raceway ponds can be used to cultivate microalgae for purposes such as wastewater treatment and feedstock for animal feeds and biofuels. Besides nitrogen assimilation in biomass, nitrification can be a wastewater treatment mechanism but one that is hindered by the low nighttime dissolved oxygen concentrations (DO) common in wastewater treatment raceways. The large diel difference in pond conditions and changing influent wastewater quality also raises the question of the optimal frequency and timing of grab sample collection, to obtain representative water quality data. Three sets of triplicate pilot raceways (1,000-L, 0.30-m deep, fed primary clarifier effluent) were operated at an …

Eeg Classification Using Residual Neural Networks, Eren Esener

Electrical Engineering

There is a growing desire to understand the EEG (electroencephalogram) signals related with brain activities. In order to analyze EEG signals, they first must be measured by sensors, which induces a lot of noise; then these signals are classified to understand the intended actions. In many cases a neural network is used as the algorithms for classification. A residual neural network (ResNet) is an artificial neural network (ANN) of a kind that are related with the pyramidal cells in the cerebral cortex. The goal of this work is to investigate the viability of ResNets for classifying EEG signals for hand …
