Effects Of Weak Electric Fields On Long-Term Synaptic Plasticity, Gregory Kronberg

Dissertations and Theses

Transcranial direct current stimulation (tDCS) is a technique where a weak direct electrical current is applied to the scalp with the goal of stimulating the brain. There is tremendous interest in the use of tDCS for treating brain disorders and improving brain function. However, the effects of tDCS have been highly variable across studies, leading to a debate over its efficacy. A major challenge is therefore to design tDCS protocols that yield predictable effects, which will require a better understanding of its basic mechanisms of action. One commonly discussed mechanism is that tDCS may alter synaptic plasticity, but the biophysics …

Unique Image Representation As A Tensor, Bharat Rosanlall

Dissertations and Theses

This thesis presents a two dimensional orthonormal transform that represents an image as coefficients in 4 independent channels. The salient feature of these coefficients is that they contain complete position spatial frequency information about the image, in a sense that the original image can be reconstructed from these coefficients with negligible error. These coefficients can be used in various machine learning, AI , and other tasks where data features are used. Popular convolutional layer used in various neural networks reduces information and can not reconstruct original image. In this thesis , we present several examples where these coefficients are used …

V-Slam And Sensor Fusion For Ground Robots, Ejup Hoxha

Dissertations and Theses

In underground, underwater and indoor environments, a robot has to rely solely on its on-board sensors to sense and understand its surroundings. This is the main reason why SLAM gained the popularity it has today. In recent years, we have seen excellent improvement on accuracy of localization using cameras and combinations of different sensors, especially camera-IMU (VIO) fusion. Incorporating more sensors leads to improvement of accuracy,but also robustness of SLAM. However, while testing SLAM in our ground robots, we have seen a decrease in performance quality when using the same algorithms on flying vehicles.We have an additional sensor for ground …

Eu Air Passengers’ Rights Past, Present, And Future: In An Uncertain World (Regulation (Ec) 261/2004: Evaluation And Case Study), Sarah Jane Fox, Luis Martín-Domingo

Journal of Air Law and Commerce

Passenger rights have continued to be strengthened following deregulation in the European Union (EU—previously the European Community) with common rules on compensation and assistance to passengers in the event of denied boarding, cancellation, and long flight delays. In January 2020, the European Commission (EC) stated that “these rights need to be better known and easier to understand and enforced.” This article considers the emerging role of Claims Management Companies (CMCs) as a step to aid passengers in achieving redress against airlines, undertaking a case study of a CMC in Spain.

The research also addresses the complexities of airline passenger rights, …

Bacterial Community Dissimilarity In Soils Is Driven By Long-Termland-Use Practices, Aditi Sengupta, Janani Hariharan, Parwinder Grewal, Warren A. Dick

School of Earth, Environmental, & Marine Sciences Faculty Publications

Land‐use practices impact soil microbial functionality and biodiversity, with reports suggesting that anthropogenic activities potentially result in reduced microbial functions and loss of species. The objective of this study was to assess the effect of long‐term (>50 yr) land use (natural forest and grassland, and agricultural land) on soil bacterial community structure. A high‐throughput sequencing‐by‐synthesis approach of the 16S rRNA gene was used to study bacterial community and predicted functional profiles of Alfisols, as affected by variables including land‐use (forest, grass, agricultural) and soil/crop management (rotation and tillage) in long‐term experimental plots in Hoytville, OH. The distribution of the …

Architectonica Karsteni Rutsch, 1934 (Gastropoda: Architectonicidae) In Seamounts Of The Nazca-Desventuradas Marine Park: First Evidence Of An Extant Population In Chilean Waters Since The Miocene, Cynthia M. Asorey, Javier Sellanes, Erin E. Easton, Rüdiger Bieler, Ariadna Mecho

School of Earth, Environmental, & Marine Sciences Faculty Publications

The presence of Architectonicidae in Chile was previously recorded only from fossil material of eight species present during the Lower Miocene, when Architectonica karsteni had a geographic range that extended from Costa Rica to central Chile (34°S). No evidence of the presence of the family in Chile after the Lower Miocene have been reported. As part of this study, we report the discovery of A. karsteni at four seamountsat ~200 m water depth in the recently created Nazca-Desventuradas Marine Park, located ~900 km west of continental Chile. Morphological identification was based on protoconch diameter, coloration patterns, and teleoconch sculpture. We …

Application Of Optical Trapping To Obtain Single-Source Str Profiles From Forensically Relevant Body Fluid Mixtures With Modified Dna Analysis Workflow, Benjamin J. O'Brien

Master of Science in Forensic Science Directed Research Projects

Current methods of mixture separation in forensic DNA laboratories typically deconvolute the mixture after analysis using statistical analysis or probabilistic genotyping. To save time and effort of labs already backlogged, a method to separate mixtures on a cellular level before analysis needs to be developed. Optical trapping is a method that uses a focused 1064 nm laser to manipulate cells. Previous research has shown that approximately 50 spermatozoa or 15 leukocytes from a liquid sample are required to produce a full STR DNA profile. It was found that the number of spermatozoa required remains constant when the method of sample …

Geochemical Constraints On Mantle Sources And Basalt Petrogenesis In The Strait Of Sicily Rift Zone (Italy): Insights Into The Importance Of Short Lengthscale Mantle Heterogeneity., John C. White, David A. Neave, Silvio G. Rotolo, Don F. Parker

EKU Faculty and Staff Scholarship

Igneous activity from the late Miocene to historic time (most recently 1891 ce) in the Strait of Sicily has created two islands (Pantelleria and Linosa) and several seamounts. These volcanoes are dominated by transitional (ol+hy-normative) to alkaline (ne-normative) basaltic lavas and scoriae; peralkaline felsic rocks (trachyte-rhyolite) crop out only on Pantelleria. Although most likely erupted through continental crust, basalts demonstrate no evidence of crustal contamination and are geochemically similar to oceanic island basalts (OIB). Despite their isotopic similarities, there are considerable compositional differences with respect to major and trace element geochemistry both between and within the two islands that are …

What Do Lawyers Contribute To Law & Economics?, Robert E. Scott, George G. Triantis

Faculty Scholarship

The law-and-economics movement has transformed the analysis of private law in the United States and, increasingly, around the world. As the field developed from 1970 to the early 2000s, scholars have developed countless insights about the operation and effects of law and legal institutions. Throughout this period, the discipline of law-and-economics has benefited from a partnership among trained economists and academic lawyers. Yet the tools that are used derive primarily from economics and not law. A logical question thus demands attention: what role do academic lawyers play in law-and-economics scholarship? In this Essay, we offer an interpretive theory of the …

© 2013 IEEE. Alzheimer's disease (AD) is a neurodegenerative condition that affects the central nervous system and represents 60% to 70% of all dementia cases. Due to an increased aging population, the number of patients diagnosed with AD is expected to exceed 131 million worldwide by 2050. The disease is characterized by various clinical symptoms and pathological features that define three main sequential decline stages, namely, early/mild, intermediate/moderate and late/severe stages. Although it is considered irreversible, early diagnosis of AD is highly desirable to help preserve cognitive function. However, early diagnosis is difficult due to different factors, including the patient-specific …

Deconstructing The Bright Future Of Steam And Design Thinking, Mark Graham

Faculty Publications

The emphasis on science, technology, engineering, and math (STEM) disciplines in schools has caused advocates for art education to propose the addition of the arts to the study of STEM, transforming STEM into STEAM. Many educators see STEAM as a way to engage students with interdisciplinary topics and to integrate the arts within the school curriculum (Allina, 2018;Katz-Buonincontro, 2018; Maeda, 2013; Sousa & Pilecki,2018; Watson, 2016). One method of implementing STEAM is Design Thinking (Henriksen, 2017). STEAM education and Design Thinking are both models for interdisciplinary collaboration and problem solving to foster economic innovation, develop 21st-century skills and entrepreneurial literacy, …

A Graph Theoretical Approach To The Dollar Game Problem, Rachel Koch

Theses and Dissertations

In this thesis we consider a problem in Graph Theory known as the Dollar Game. The Dollar game was first introduced by Matthew Baker of the Georgia Institute of Technology in 2010. It is a game of solitaire, played on a graph, and is a variation of chip firing, or sand-piling games. Baker approached the problem within the context of Algebraic Geometry. It is the goal of this paper to provide an overview of the necessary graph theory to understand the problem presented in this game, as well as background on chip firing games, their history and evolution. Finally we …

From Small Beginnings To Large-Scale Harm: On Demagoguery And Misogyny In The Classroom And Writing Center, Shannon Roberson

Theses and Dissertations

My project is grounded in the rhetorical concept of aretê—excellence or virtue—as it relates to education and educational spaces within demagogic and misogynist cultural forces. The problems of demagoguery and misogyny stem from small-scale perpetuation of agonistic norms that go unaddressed in U.S. culture, a culture that is deeply identity-driven. These forces persist on social media platforms and within patriarchal systems of education.

For my project, I suggest rhetorical media literacy education of small-scale demagoguery moments on social media as a way to bring awareness to larger-scale events. On a micro-scale, social media influencers cultivate behaviors that mimic demagogic …

Arabic Beyond Arabic, Abir Zakzok

Theses and Dissertations

Arabic is the best and the most complicated language of all time!” Even though this statement seems like an exaggeration, it is what I grew up hearing; from my Arab parents as a child, my Arab teachers as a student, and my Arab customers as a salesperson. The Arabic language has a significant role in Arabs’ identity, yet most Arabs only scratch the surface and do not fully grasp the embedded meaning of the language. I have long been fascinated by the relationship between language and community as well as how it translates to design - specifically, the relationship between …

Reaction Profiling Of Extracellular Protein Phosphorylation Through A Microfluidic Reactor Coupled With Raman Spectroscopy, Abigail Casey

Theses and Dissertations

Diseases and disorders in the human body are considered abnormalities of proper cellular function. Understanding the signal transduction mechanisms that cause these abnormalities is crucial to developing earlier detection methods, better treatment options and effective cures. While current diagnostic procedures are powerful tools in diagnosing diseases, they are ineffective in informing physicians on the real-time behavior of the signal transduction mechanisms associated with diseases and disorders. Currently, disease progression is monitored over time through routine patient visits and testing by one or more of the above techniques. By developing an approach that can monitor structural and conformational changes of proteins …

Metal-Oxide Nanostructures Fabricated From Reactive Laser Ablation In Liquid, Mallory G. John

Theses and Dissertations

The development of metal-oxide nanostructures is a growing area due to their applications in diverse fields spanning energy conversion and storage, chemical manufacturing, and en- vironmental technology. This interest in catalytically active nanomaterials has prompted the synthesis and investigation of highly functionalized nanoparticles (NPs), including core- shell, silicate-stabilized, and bi- and multi-metallic nanocomposites. While wet-chemical synthesis methods of metal-oxide nanostructures have led to several morphologies, compositions, and shapes, these syntheses often require high temperatures, toxic solvents or reducing agents, and long reaction times.

Laser synthesis and processing of colloids (LSPC) encompasses both ‘top down’ and ‘bottom up’ approaches to synthesize …

Redox-Active Porous Organic Materials For Electrochemical Energy Storage Applications, K. Shamara Weeraratne

Theses and Dissertations

As the demand for renewable energy technologies grows, so does the need for cheaper, more efficient rechargeable batteries to store the energy. While lithium-ion battery (LIBs) technology is well established, it suffers from limited lithium supplies. Furthermore, the highly toxic transition metals used in the electrodes places a huge burden on the environment. Therefore, replacing lithium with more economical sodium metal in rechargeable batteries (i.e. sodium-ion batteries, SIBs) has garnered considerable attention. Despite the fact that sodium and lithium share similar electrochemical properties, which may cause the transition from lithium to sodium easier, the larger ionic radius of Na^{+ …}
