Statistical Analysis Of Aquifer Hydraulic Properties By A Continuous Pumping Tomography Test: Application To The Boise Hydrogeophysical Research Site, Kan Bun Cheng, Gedeon Dagan, Warren Barrash, Michael Cardiff, Avinoam Rabinovich

Geosciences Faculty Publications and Presentations

Characterizing aquifer heterogeneity is paramount for accurate flow and transport modeling. In this work, we present a new approach for statistical analysis of hydraulic properties in continuous pumping tomography tests of a phreatic aquifer. The method entails determining equivalent hydraulic conductivity (K_eq), specific storage (S_s,eq), and specific yield (S_y,eq) at many locations in the field and then calculating statistical moments of the equivalent properties, assuming they are random space variables. Equivalent properties are defined as the ones pertinent to a homogeneous aquifer for which the head time …

New Jump Operators On Equivalence Relations, John D. Clemens, Samuel Coskey

Mathematics Faculty Publications and Presentations

We introduce a new family of jump operators on Borel equivalence relations; specifically, for each countable group Γ we introduce the Γ-jump. We study the elementary properties of the Γ-jumps and compare them with other previously studied jump operators. One of our main results is to establish that for many groups Γ, the Γ-jump is proper in the sense that for any Borel equivalence relation E the Γ-jump of E is strictly higher than E in the Borel reducibility hierarchy. On the other hand, there are examples of groups Γ for which the Γ-jump is not proper. To establish properness, …

Designing Single Molecule Diode, Tinsae Alem

Longwood Senior Theses

The field of single molecule electronics is based on using single molecule devices to control current in electronic circuits. One area of interest is to reproduce the functionality of traditional components such as wires, switches, and diodes using single molecule junctions. We used computational chemistry to design diodes to investigate what molecular features affect their performance including using different donors, acceptors, and connectors. A comparison of the diode's performance was made by comparing the rectification ratio. About 50 diodes were designed and tested, with rectification ratios ranging from 1.0 to 5.8. The results indicate that multiple factors have a significant …

The Effect Of Aphantasia On Visual Memory Retention, Joshua M. Bain

Longwood Senior Theses

Aphantasia is the inability to create mental imagery which affects approximately 2% of people in the world (Zeman et al., 2015). The vividness of visual imagery questionnaire (VVIQ) was used to sort participants into four groups (aphantasia, low, medium, and high vividness) based on their vividness score with aphantasia participants scoring a 16 (the minimum). I tested the effect of aphantasia on scores of a visual memory recall test. Participants saw two of six possible images and answered five questions per image. Analysis of the results did not show any significant difference between aphantasia and non-aphantasia scores on the recall …

Avian Species Distribution Models: Using Location Data To Inform Management Decisions, Marilyn E. Wright

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Both state and federal wildlife agencies strive to conserve and protect wildlife and their habitats as an important public resource. Applied management decisions often rely on being able to obtain data that can efficiently and effectively enhance the understanding of these systems for informing management actions. Wildlife managers often focus efforts on a small subset of species from an ecosystem, typically called focal species, who can serve as surrogates for understanding the health and function of the system. Models that consider how these focal species interact with the ecosystem are often used to better understand important aspects of their life …

Identifying And Minimizing Underspecification In Breast Cancer Subtyping, Jonathan Cheuk-Kiu Tang

Master's Theses

In the realm of biomedical technology, both accuracy and consistency are crucial to the development and deployment of these tools. While accuracy is easy to measure, consistency metrics are not so simple to measure, especially in the scope of biomedicine where prediction consistency can be difficult to achieve. Typically, biomedical datasets contain a significantly larger amount of features compared to the amount of samples, which goes against ordinary data mining practices. As a result, predictive models may fail to find valid pathways for prediction during training on such datasets. This concept is known as underspecification.

Underspecification has been more accepted …

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The Southern Ocean paleoceanography provides key insights into how iron fertilization and oceanic productivity developed through Pleistocene ice-ages and their role in influencing the carbon cycle. We report a high-resolution record of dust deposition and ocean productivity for the Antarctic Zone, close to the main dust source, Patagonia. Our deep-ocean records cover the last 1.5 Ma, thus doubling that from Antarctic ice-cores. We find a 5 to 15-fold increase in dust deposition during glacials and a 2 to 5-fold increase in biogenic silica deposition, reflecting higher ocean productivity during interglacials. This antiphasing persisted throughout the last 25 glacial cycles. Dust …

Veratrum Parviflorum Poisoning: Identification Of Steroidal Alkaloids In Patient Blood And Breast Milk, Jared T. Seale, Xinzhu Pu, Owen M. Mcdougal

Chemistry and Biochemistry Faculty Publications and Presentations

Introduction

The Veratrum genus is composed of plants containing a diverse set of steroidal alkaloids. Veratrum plant material has been utilized for centuries as herbal medicines, however the alkaloids have such a low therapeutic index that they are not used in modern medicine. Here we report an incident of inadvertent ingestion of V. parviflorum by hikers in Georgia that allowed detection, and in several instances identification of alkaloids from the plant, and correlated their presence within patient blood and breast milk specimens.

Case history

Eight patients, three male and five female, presented in the spring of 2020 and 2021 with …

A Simple Technique To Obtain The Response Of A Structure Considering Soil-Structure Interaction (Ssi), Smit Kamal

Manipal Journal of Science and Technology

In the conventional analysis of structures, the effect of soil-structure interaction (SSI) is generally neglected. Analysis of the structures without considering the effect of SSI may not be a realistic approach for all the cases particularly when structures are subjected to forces due to earthquakes. One of the limitations of SSI consideration in the analysis is due to the complexity involved in such analysis and this is the main reason for neglecting SSI in the analysis. In this paper, an alternative method for obtaining a structure response that is similar to a structure taking SSI is proposed. In this approach, …

Multiscale Topology Optimization With A Strong Dependence On Complementary Energy, Dustin Dean Bielecki

All Dissertations

A discrete approach introduces a novel deep learning approach for generating fine resolution structures that preserve all the information from the topology optimization (TO). The proposed approach utilizes neural networks (NNs) that map the desired engineering properties to seed for determining optimized structure. This framework relies on utilizing parameters such as density and nodal deflections to predict optimized topologies. A three-stage NN framework is employed for the discrete approach to reduce computational runtime while maintaining physics constraints.

A continuous representation that uses complementary energy (CE) methods to solve a representative element's homogenized properties consists of an embedded structure that is …

Detecting Selfish Mining Attacks Against A Blockchain Using Machine Learing, Matthew A. Peterson

Graduate Theses and Dissertations (2019 - present)

Selfish mining is an attack against a blockchain where miners hide newly discovered blocks instead of publishing them to the rest of the network. Selfish mining has been a potential issue for blockchains since it was first discovered by Eyal and Sirer. It can be used by malicious miners to earn a disproportionate share of the mining rewards or in conjunction with other attacks to steal money from network users. Several of these attacks were launched in 2018, 2019, and 2020 with the attackers stealing as much as $18 Million. Developers made several different attempts to fix this issue, but …

The Importance And Implementation Of Kinesthetic Learning In The English Classroom, Emma Crandall

Senior Honors Theses

This paper examines different educators’ and researchers’ activities for kinesthetic learners and discusses how they can be applied to the English classroom in literature, writing, and language. The first section delves into the difficulty associated with but ultimate importance of including kinesthetic learning activities for both kinesthetic and non-kinesthetic learners due to the benefits of active learning. Subsequently, it looks for synthesis between different types of kinesthetic activities, dividing them into the categories of manipulatives, commonly accepted classroom activities with kinesthetic add-ons, and kinesthetic-centered activities. The ways each activity can be used, including its benefits and disadvantages, are discussed, and …

Predicting Energy Intake In Adults Who Are Dieting And Exercising, Corey Gerving, Robert Lasater, James Starling, Danielle M. Ostendorf, Leanne M. Redman, Chad Estabrooks, Kevin Cummiskey, Vincent Antonetti, Diana M. Thomas

Clinical Research Faculty Publications

Background: When a lifestyle intervention combines caloric restriction and increased physical activity energy expenditure (PAEE), there are two components of energy balance, energy intake (EI) and physical activity energy expenditure (PAEE), that are routinely misreported and expensive to measure. Energy balance models have successfully predicted EI if PAEE is known. Estimating EI from an energy balance model when PAEE is not known remains an open question. Objective: The objective was to evaluate the performance of an energy balance differential equation model to predict EI in an intervention that includes both calorie restriction and increases in PAEE. Design: The Antonetti energy …
