Impact Of Interface Condition On Performance Of Thin Asphalt Overlays, Cheng Zhu

Open Access Theses & Dissertations

Asphalt overlay has been widely used in the United States as a cost-effective maintenance approach to keep the pavement in a satisfactory condition. In recent years, many studies have been conducted to investigate the overlay asphalt mix design, overlay pavement design, and quality control/quality assurance for the asphalt overlay pavement. In Texas, thin overlays (lift thickness less than 2 in.) and ultra-thin overlays (lift thickness of 0.5 in. to 0.75 in.) seem to be more beneficial than conventional asphalt overlays. For this type of overlay, the bonding condition between the overlay and existing AC layer is crucial for the pavement …

Density Functional Calculations On Single Molecular (1d) And Van Der Waals Bi -Layered (2d) Magnets., Md Shamsul Alam

Open Access Theses & Dissertations

Low-dimensional magnetic materials show novel properties that is not seen in bulk magnets. The weak interactions such as spin-orbit interactions, electron correlation, van der Waals interaction in case magnetic bi-layers, play an important role in determining the properties of the system. Using density functional theory, we computationally investigated two categories of magnetic material- 1: Single Molecular Magnets (SMM) 2: Van der Waals layered Cr-Halide magnets. We used different classes of density functionals to examine the spin ordering and magnetic anisotropy barriers in several single molecule magnets - Mn12, Co4, Ni4, V15. We find that the magnetic anisotropy barrier significantly depends …

General Penalized Logistic Regression For Gene Selection In High-Dimensional Microarray Data Classification, Derrick Kwesi Bonney

Open Access Theses & Dissertations

High-dimensional data has become a major research area in the field of genetics, bioinformatics and bio-statistics due to advancement of technologies. Some common issues of modeling high-dimensional gene expression data are that many of the genes may not be relevant. Also, reducing the dimensions of the data using penalized logistic regression is one of the major challenges when there exists a high correlation among genes. High-dimension data correspond to the situation where the number of variables is greater or larger than the number of observations. Gene selection proved to be an effective way to improve the results of many classification …

The Influence Of Over-Ground Versus Treadmill Walking On Gait Mechanics In Children With Autism Spectrum Disorder, Emily Ann Chavez

Open Access Theses & Dissertations

Treadmill (TM) walking may be a way to combat obesity and socio-behavioral barriers associated with children with Autism Spectrum disorder (ASD), though tripping-risk has not yet been assessed for this population through use of spatial-temporal gait analysis. The aim of this project/study was to examine spatial-temporal walking mechanics and lower extremity tripping descriptors between over ground (OG) and TM gait conditions in children with ASD compared to children with neurotypical development (NT). Kinematics data were obtained through tridimensional motion analysis where participants, 10 children with ASD and 9 age- and sexmatched NT controls, were outfitted with retroreflective markers on their …

Effects Of Spatial Location Of Auditory Tones On Pitch Discrimination, Ashley G. Flagge, Julie M. Estis, Robert E. Moore

Ashley Flagge Publications

Pitch discrimination accuracy has been found to be affected by many factors, including handedness, musical training, interfering stimuli, and spatial location of the auditory stimulus. Separating the stimulus input location of interference tones from initial (reference) and final (comparison) tones leads to more accurate pitch discrimination, but the effects of spatial location relationships between the reference, interference, and comparison tones have not been fully explored. This study examined the impact of stimulus spatial location in 24 young, non-musician females. Participants determined whether the pitch of reference and comparison tones was the same or different in 20 pitch discrimination conditions with …

The Contribution Of Frequency Discrimination Ability To Auditory Temporal Patterning Tests In Children, Ashley G. Flagge, Tara M. Davis, Victoria Henbest

Ashley Flagge Publications

Purpose: The Pitch Patterns Test (PPT) and Duration Patterns Test (DPT) are clinical auditory processing tests that evaluate temporal patterning skills based on pitch (PPT) or duration (DPT) aspects of sound. Although temporal patterning tests are categorized under the temporal processing domain, successful performance on the PPT also relies on accurate pitch discrimination. However, the relationship between pitch discrimination ability and temporal patterning skills have not been thoroughly evaluated. This study examined the contribution of pitch discrimination ability to performance on temporal patterning in children through the use of a pitch discrimination task and the PPT …

Auditory Consonant Trigrams: Construct And Criterion Validity Update, Katharine Elizabeth Lindberg

Theses and Dissertations

The Auditory Consonant Trigrams (ACT) has historically been used in research and clinical settings as a measure of working memory ability, though previous research has failed to identify the precise cognitive processes and abilities measured by the task. The ACT total score (ACT T) has been shown to be sensitive to numerous clinical neurological and psychological populations (i.e., TBI, ADHD, MS, MDD). Alternatively, little is known about the ACT perseveration score (ACT P), the current study aimed to identity the ACT T and ACT P’s relationships to other neuropsychological measures and their clinical utility within diverse clinical/neurological presentations. In a …

Masculine Honor Ideology: An Unrecognized Risk Factor For Aggressive Behavior, Mara Norton-Baker

Theses and Dissertations

The societal and personal costs of aggressive and violent behavior have reached alarming levels within the United States. In the literature, several personality and personal factors have been uncovered as valuable predictors of aggressive and violent behavior. However, it may be the case another variable has been unduly discounted in its link to aggression. Masculine Honor Ideology (MHI) refers to a set of beliefs that dictate men must respond aggressively to threat or insult in order to maintain their ideal masculine reputation. The intent of the current study is to demonstrate the robust relationship that exists between MHI and lifetime …

Hiv Law And Policy In The United States: A Tipping Point, Scott Skinner-Thompson

Publications

The fight to effectively treat and stop the spread of the human immunodeficiency virus (HIV) has made meaningful progress both in the United States and globally. But within the United States that progress has been uneven across various demographic groups and geographic areas, and has plateaued. While scientific advances have led to the development of medicine capable of both treating and preventing HIV, law and policy dictate who will have ready access to these medicines and other prevention techniques, and who will not. Law and policy also play a crucial role in determining whether HIV will be stigmatized, discouraging people …

(Carbon) Farming Our Way Out Of Climate Change, Alexia Brunet Marks

Publications

Numerous climate-related emergencies highlight the challenges and urgency posed by climate change: the 2018 Intergovernmental Panel on Climate Change (IPCC) Report, the Global Climate Action Summit in California and international student walkouts, to name a few. While the IPCC Report sent an urgent cry to reduce total emissions and to achieve specific results—45% reduction by 2030 and net-zero emissions by 2050—reductions need to be combined with capturing and storing atmospheric carbon dioxide. Scientific studies have shown that an annual increase of 0.4% of carbon stored in soils would make it possible to stop the present increase in atmospheric CO2.

Taming America's Sugar Rush: A Traffic-Light Label Approach, Alexia Brunet Marks

Publications

Excess added sugar negatively impacts health and can lead to a litany of problems, such as diet-related chronic diseases, e.g., diabetes, cancer, heart disease, and obesity, costing Americans millions in rising medical bills each year. Even more, new studies reveal that individuals with these underlying chronic diseases are at a higher risk of complications from COVID-19 and other viruses compared to those who are deemed healthy. And yet added sugars are difficult to avoid because unlike naturally occurring sugars found in fruits, vegetables, and milk, these sweeteners are added during food processing and preparation.

The problem is that while consumers …

Regulatory De-Arbitrage In Twenty-First Century Cures Act's Health Information Regulation, Craig Konnoth

Publications

Health data regulation can be thought of at two levels. First, the micro- level of regulation has to do with Electronic Health Records (EHRs). Second, the macro-level concerns the networks on which EHRs are transmitted. The micro- and macro-levels of regulation interact. For example, EHRs need to be configured so that they can be transmitted on mandated networks. As a result, the lines do sometimes blur.

That said, the 21st Century Cures Act (Cures) clearly takes a dual approach to regulation. Cures was passed in December 2016 on a bipartisan basis. Its mandate was to address health data regulation at …

Simulation Of Notch Driven Hydraulic Fracture In Open Hole Completion, Nejma Djabelkhir

Theses and Dissertations

Hydrocarbon production from unconventional plays, including shale oil and gas, has begun in the USA since nearly two decades ago and experienced a rapid growth. Horizontal drilling and multistage hydraulic fracturing (HF) are the prime technologies in development and stimulation of unconventional reservoirs. Open hole (OH) and cased hole (CH) are the primary completion methods used in unconventional reservoirs. OH compared to cased hole (CH) completion is more desired as it requires less operation cost and time while it results in more production due to larger area of wellbore exposure to the formation. However, OH completion is susceptible to near …

In this study, we examine on intraday basis Ether-the token or cryptocurrency based on the Ethereum platform. Ether is the second largest crypto-currency, together with Bitcoin they dominate the cryptocurrency universe and account for almost 70% of combined market share. Similar to Bitcoin, Ethereum experienced rapid growth in price from a few cents per Ether after its introduction in 2015 reaching maximum of $1,432.88 on January 13, 2018. In this paper, we study whether Ethereum crypto-currency is a hedge, diversifier or a safe haven asset. We find that Ethereum crypto-currency is a hedge against the US stock and gold markets. …

The Right Family, Noa Ben-Asher, Margot J. Pollans

Elisabeth Haub School of Law Faculty Publications

The family plays a starring role in American law. Families, the law tells us, are special. They merit, among others, tax deductions, testimonial privileges, untaxed inheritance, parental presumptions, and, over the course of the twentieth century, the Supreme Court has expanded individual rights stemming from familial relationships. In this Article, we argue that family matters as much for when it is ignored as for when it is featured. We shed light on the use of the family in the law by contrasting policies in which the family is the key unit of analysis with others in which it is not. …

A novel non-coherent, low-power, area-efficient binary phase-shift keying demodulator for wireless implantable biomedical microsystems is proposed. The received data and synchronized clock signal are detected using a delayed digitized format of the input signal. The proposed technique does not require any kind of oscillator circuit, and due to the synchronization of all circuit signals, the proposed demodulator can work in a wide range of biomedical data telemetry common frequencies in different process/temperature corners. The presented circuit has been designed and post-layout-simulated in a standard 0.18 µm CMOS technology and occupies 17 × 27 µm2 of active area. Post-layout simulation results …

Determination Of Demagnetizing Factors Using First-Order Reversal Curves And Ferromagnetic Resonance, K. S. Muster, R. Heindl

Faculty Research, Scholarly, and Creative Activity

We present a method to quantitatively analyze magnetizing or demagnetizing interactions in arrayed nano-magnets by combining first-order reversal curve (FORC) and ferromagnetic resonance (FMR) measurement data. We develop a function to predict the resulting FORC distribution given: (1) a Gaussian intrinsic distribution in terms of the internal field and (2) a mean interaction field proportional to the sample's magnetic moment. We then perform least-squares regression of our model on experimental FORC measurements of a nanowire array and of a thin film. Combining the obtained interaction field with an FMR fit result allows us to algebraically solve for the effective axial …
