Top Quark Produced Through the Electroweak Force: Discovery Using the Matrix Element Analysis and Search for Heavy Gauge Bosons Using Boosted Decision Trees

Description: The top quark produced through the electroweak channel provides a direct measurement of the V{sub tb} element in the CKM matrix which can be viewed as a transition rate of a top quark to a bottom quark. This production channel of top quark is also sensitive to different theories beyond the Standard Model such as heavy charged gauged bosons termed W{prime}. This thesis measures the cross section of the electroweak produced top quark using a technique based on using the matrix elements of the pro… more

Bio-Inspired Material Surfaces with Self-cleaning, Micromanipulation and Water Collection

Description: Geckos are famous for the skill of switchable adhesion that they use to stick on various surface while keep their fingers super clean. In the dissertation, a unique mechanism was discovered to explain gecko self-cleaning phenomena. Using atomic force microscopy (AFM), we managed to compare the microparticle-substrate adhesion and the microparticle-seta adhesion with a single seta bonded to the AFM cantilever. A dynamic effect was approved that high pulling-off speed could increase the micropart… more

Development and Testing of Gold(I) and Europium(III) Based Sensors for Environmental Applications

Description: This dissertation focuses on the development, characterization, and analysis of luminescent materials and coatings for sensing applications, including CO2, heavy metals, and silver. Chapter 2 involves the use of a gold(I) pyrazolate trimer that is able to detect silver ions with an AgNP medium. Detection of silver is vital, because there is an influx of silver into our environment caused by the increased use of AgNP. Therefore, having a sensor that is able to differentiate between and detect on… more

Substrate Nanotopography and Stiffness Modulation of Cell Behavior

Description: The physical characteristics (i.e., nanostructure and stiffness) of the extracellular matrix where cells reside have been shown to profoundly affect numerous cellular events in vivo and also been employed to modulate cell behavior in vitro, yet how these physical cues regulate cell behavior is still elusive. Therefore, we engineered a variety of nanotopographies with different shapes and dimensions, and investigated how the nanotopographical cue, through focal adhesions-cytoskeleton-nucleus pat… more

Computational Studies of C-H Bond Activation and Ethylene Polymerization Using Transition Metal Complexes

Description: This work discusses the C-H bond activation by transition metal complexes using various computational methods. First, we performed a DFT study of oxidative addition of methane to Ta(OC2H4)3A (where A may act as an ancillary ligand) to understand how A may affect the propensity of the complex to undergo oxidative addition. Among the A groups studied, they can be a Lewis acid (B or Al), a saturated, electron-precise moiety (CH or SiH), a σ-donor (N), or a σ-donor/π-acid (P). By varying A, we seek… more

A Study on Flat-Address-Space Heterogeneous Memory Architectures

Description: In this dissertation, we present a number of studies that primarily focus on data movement challenges among different types of memories (viz., 3D-DRAM, DDRx DRAM and NVM) employed together as a flat-address heterogeneous memory system. We introduce two different hardware-based techniques for prefetching data from slow off-chip phase change memory (PCM) to fast on-chip memories. The prefetching techniques efficiently fetch data from PCM and place that data into processor-resident or 3D-DRAM-resi… more

Transhumanism: An Ontology of the World's Most Dangerous Idea

Description: Transhumanism is the name given to the cultural and philosophical movement which advocates radical human technological enhancement. In what follows, I use perspectives drawn from existential philosophy to problematize transhumanists' desire to recast human finitude as a series of technical problems with technical solutions. The ontological account of transhumanism offered here questions the assumed benefit and inevitability across six chapters. Following an introductory chapter, Chapter 2 intro… more

Exploration of Genome Length, Burst Time, and Burst Size of Streptomyces griseus Bacteriophages

Description: Since phages use the host resources to replicate themselves after infection, the different sizes of the phage genome should influence the replication rate. We, therefore, hypothesized that the smaller genomes should burst the cell faster than the larger ones. As well, the shorter genomes would have greater burst sizes because they should replicate faster. Here, we obtained 16 phages of various genome length. All phages were isolated on Streptomyces griseus and available in our phage bank at the… more

What Experiences do Trans* Students have during Their Time in College?

Description: Although trans* students often face greater levels of discrimination, harassment, and hostility on college campuses than their cisgender peers, research indicated that they can succeed by developing and honing survival strategies, such as resilience and being part of a trans* kinship network that resists trans* oppression. Having the support of family, and by taking the risk to cultivate relationships while in college also improves the likelihood of persistence through college. The term trans* … more

"A Very Fine Piece of Writing": Parnell and the Joycean Text, 1905-1922

Description: Charles Stewart Parnell was James Joyce's most significant political influence to a degree that has yet to be fully acknowledged or explored. This thesis proposes a "theory of Parnell" in Joyce's works up to the end of Ulysses, arguing that close attention to Parnell's evolution points to a significant shift in the evolution of Joyce's literary forms. In Joyce's juvenilia, political writings, and early fiction, Parnell always appears with a heroic, even Messianic, cast, which the most significa… more

Creating a Verbal Community for Describing Emotional Responses within a Contingency Lens: The Effects of a Brief Training Workshop

Description: Observing emotional responses is recognized as a valuable clinical skill in a variety of professions, including applied behavior analysis. Emotional responses can flag possible contingencies thereby guiding a behavior analyst to better select valid measures, goals, and procedures. Additionally, emotional responses can be goals in and of themselves. The purpose of the present study was to evaluate the effects of a workshop on the observation and description of emotional responses by behavior ana… more

Can Observing Behavior Predict Performance in Conditional Discriminations?

Description: Prompts are implemented often in training procedures, to include conditional discriminations, and this can lead to prompt dependency. The current study extends a prior study that suggested that the effectiveness of supplementary visual stimuli displaying the sample and comparison was dependent on the timing in relation to the selection task, presented as a prompt or feedback, in a match-to-sample procedure. The current research examines if the differences in that effectiveness were due to diffe… more

When to correct errors when teaching a new task to children with autism

Description: The purpose of this experiment was to investigate Tosti's proposal about the timing of feedback. The study examined whether it is better to correct immediately after the error occurs or whether it is better to wait until immediately before the next opportunity to respond. In addition, it aimed to determine whether corrections delivered at different times produced different learner affects. Four children with autism were taught to label two sets of pictures under the two different conditions. Re… more

Fearful to Friendly (F2F): a Constructional Fear Treatment for Domestic Cats Using a Negative Reinforcement Shaping Procedure in a Home Setting

Description: Feral and fearful cats and kittens in animal shelters are not likely to be adopted as companion animals because they emit fearful or aggressive behaviors in the presence of humans. The purpose of the fearful to friendly (F2F) research was to investigate a shaping procedure to increase friendly behaviors of feral and fearful domestic cats and kittens with the goal of achieving animal shelters’ adoptability criteria. The results showed the F2F procedure was a safe and very effective procedure t… more

Untangling the Effects of Scheduled Exercise on Child Engagement, Stereotypy, and Challenging Behavior

Description: There is limited research pertaining to the effects of exercise on the behavior of children with autism. Previous researchers focused on exploring the dimensions of the exercise itself, leaving a functional account of the effects of exercise undetermined. There is recent evidence that exercise suppresses responses maintained by automatic reinforcement. The purpose of the present study was to better identify the relevant independent variable in such research and to assess if there were different… more

What Are They Learning: a Study of Errors Produced During Behavior Acquisition Utilizing Two Prompting Procedures with a Cat

Description: Prompting methods are common amongst animal trainers, both novice and experts. However, there is little empirical evidence to demonstrate the strengths or weaknesses of common prompting procedures. The current study assessed the strengths and weaknesses during behavior acquisition of two prompting methods, luring and targeting. Luring placed an edible directly in front of the animal which guided the animal through the desired behavior. Targeting, however used a target, an arbitrary object t… more
