Context Dependent Training Data Selection For Automatic Target Detection., Tylman Michael

Electronic Theses and Dissertations

An Automatic Target Detection (ATD) algorithm is capable of identifying the location of targets of interest captured by Infra-Red imagery in vastly different contexts. ATD is often a precursor in a 2-stage methodology in order to ascertain the location and nature of a target in both military and civilian applications. In order to train an ATD algorithm, a large amount of data from varied sources is required. One drawback of this requirement is that some sources of data may harm the performance of the method in different contexts. This thesis explores utilizing an unsupervised method to identify a subset of …

Optimization, Characterization, And Comparison Of Two Luciferase-Expressing Mouse Glioblastoma Models, Louis Rodgers, Julia A. Schulz Pauly, Bryan J. Maloney, Anika M. S. Hartz, Bjoern Bauer

UK CARES Faculty Publications

Glioblastoma (GBM) is the most aggressive brain cancer. To model GBM in research, orthotopic brain tumor models, including syngeneic models like GL261 and genetically engineered mouse models like TRP, are used. In longitudinal studies, tumor growth and the treatment response are typically tracked with in vivo imaging, including bioluminescence imaging (BLI), which is quick, cost-effective, and easily quantifiable. However, BLI requires luciferase-tagged cells, and recent studies indicate that the luciferase gene can elicit an immune response, leading to tumor rejection and experimental variation. We sought to optimize the engraftment of two luciferase-expressing GBM models, GL261 Red-FLuc and TRP-mCherry-FLuc, showing differences …

“Criminalizing” Depositions In Arbitration, Mitch Zamoff

Minnesota Law Review Vols. 106:2 onward (2021-present)

Civil litigation--style deposition practice is preventing commercial arbitration from reaching its full potential as an economical, efficient alternative to a civil lawsuit. Although there is consensus among alternative dispute resolution experts that meaningful limits must be imposed on arbitration discovery to unlock the efficiency benefits of arbitration, depositions continue to feature prominently in commercial arbitrations for at least three reasons. First, civil litigators are addicted to depositions. They reflexively propose overdone deposition practice in arbitrations that replicates their litigation experience. Second, arbitrators may hesitate to disallow deposition discovery out of fear that their awards will be vacated for failure to …

Optimization Of Pre-Enrichment And Screening Methods For The Detection Of Salmonella Enterica In Meat Analog Products, Kylie Sacapano

Food Science (MS) Theses

With the growing demand and variety of meat analogs on the commercial market, there is a need to revisit the methodology for the detection of foodborne pathogens in these products. The current Food and Drug Administration (FDA) regulatory methods for Salmonella enterica detection in meat analogs follow the Bacteriological Analytical Manual (BAM) and are time-consuming and costly, requiring pre-enrichment using lactose broth (LB) with a surfactant (e.g., Triton X-100). Therefore, this study aimed to optimize pre-enrichment and screening methods for the detection of Salmonella in meat analogs by comparing the current FDA reference methods to updated techniques. To achieve this, …

A Meta-Analysis Of Seafood Species Mislabeling Rates In The United States, Sarah Ahles

Food Science (MS) Theses

Seafood is vulnerable to species mislabeling due to factors such as complex global supply chains, varying prices, and similar appearance of species. Numerous studies have been published reporting a range of mislabeling rates for various forms of seafood. However, these studies oftentimes focus on lesser-consumed species that are vulnerable to species mislabeling. As a result, the overall mislabeling rate of commercially sold seafood in the U.S. remains unknown, especially for the most consumed species. Thus, the objective of the current study was to compile the results of seafood mislabeling studies into a single resource to provide informative statistics on U.S. …

Fine-Grained Address Space Layout Randomization Through Non-Contiguous Per-Function Memory Segment Assignment, Andrew Kramer

Masters Theses & Doctoral Dissertations

Address Space Layout Randomization (ASLR) is a popular exploit mitigation provided by most modern operating systems today. ASLR works by randomizing the base address of position-independent code and data segments loaded in memory at run-time in order to make it more difficult for an attacker to guess their locations.

This design choice makes ASLR fast and efficient, but suffers from a major flaw: If an attacker is able to leak any pointer to the randomized memory mapping, they can easily calculate the corresponding base address, and in turn calculate the address of any other code or data in that segment, …

The Pam-1 Aminopeptidase Protects Against Neurodegeneration In Caenorhabditis Elegans, Caleb Coil

Honors College Theses

The deteriorating effects of neurodegenerative conditions seem inescapable for many as they age. The experimental exploration of the molecular and cellular mechanisms responsible for neurodegeneration is aided using animal models. For instance, genetic screens have identified the puromycin-sensitive aminopeptidase (PSA) as a novel effector of neurodegeneration, as mutations in PSA in fruit flies result in perturbations of neuron anatomy and an accelerated onset of neuron death. We have tested the hypothesis that PAM-1, the Caenorhabditis elegans ortholog of PSA, plays a similar role in governing neurodegeneration in nematodes. Genetic strains were created that express the green fluorescent protein (GFP) in …

Demography With Drones: Detecting Growth And Survival Of Shrubs With Unoccupied Aerial Systems, Peter J. Olsoy, Andrii Zaiats, Donna M. Delparte, Matthew J. Germino, Bryce A. Richardson, Anna V. Roser, Jennifer S. Forbey, Megan E. Cattau, T. Trevor Caughlin

Biology Faculty Publications and Presentations

Large-scale disturbances, such as megafires, motivate restoration at equally large extents. Measuring the survival and growth of individual plants plays a key role in current efforts to monitor restoration success. However, the scale of modern restoration (e.g., >10,000 ha) challenges measurements of demographic rates with field data. In this study, we demonstrate how unoccupied aerial system (UAS) flights can provide an efficient solution to the tradeoff of precision and spatial extent in detecting demographic rates from the air. We flew two, sequential UAS flights at two sagebrush (Artemisia tridentata) common gardens to measure the survival and growth of …
