Subpial Resection Of Epileptogenic Tubers: Operative Nuances And Lessons Learned, Howard L Weiner

Faculty, Staff and Students Publications

Tuberous sclerosis complex (TSC) is an autosomal dominant neurocutaneous disorder. Tubers of the central nervous system are a hallmark of the disorder and often cause epilepsy. Many TSC patients fail to achieve seizure control with medication alone. Several case series have demonstrated high seizure freedom rates after resective surgery. However, the technique for the resection of epileptogenic tubers has largely been unreported. Here the authors present 2 cases to illustrate their multistage approach for localizing and resecting the seizure onset zone in patients with TSC. At their institution, they have excellent seizure outcomes and a low complication rate with this …

AES Faculty Publications and Presentations

In a warming climate, an intensifying fire regime and higher likelihood of extreme rain are expected to increase watershed sediment yield in many regions. Understanding regional variability in landscape response to fire and post‐fire rainfall is essential for managing water resources and infrastructure. We measured sediment yield resulting from sequential wildfire and extreme rain and flooding in the upper Carmel River watershed (116 km2), on the central California coast, USA, using changes in sediment volume mapped in a reservoir. We determined that the sediment yield after fire and post‐fire flooding was 854–1,100 t/km2/yr, a factor of 3.5–4.6 greater than the …

Microbiomes In Birds: A Review Of Links To Health And Reproduction, Brent Coverdale, Sandi Willows-Munro, Leigh Combrink

Faculty, Staff and Students Publications

Microbiomes have emerged as a key component essential for maintaining the health of an organism. Additionally, the roles of microbiomes are multifaceted, some unique to specific body areas and organs while others, particularly the gut microbiome, having broader effects on the entire organism. Comparative literature is emerging that compares microbiomes across mammals and birds. Domestic poultry have been the most extensively studied relative to their role in production agriculture. These data have provided a great deal of information about the effects of diet and nutritional requirements relative to the gut microbiome, productivity, and resilience to diseases. Conversely, limited research has …

Central Venous Pressure And Impaired Renal Function In Children And Young Adults With Cardiovascular Disease, Swati Choudhry, Kyle D Hope, Kriti Puri, Joseph A Spinner, Ayse Akcan-Arikan, Jack F Price

Faculty, Staff and Students Publications

BACKGROUND: Traditionally, low cardiac output has been considered the primary hemodynamic driver of renal function and injury. Adult data suggest that central venous pressure (CVP) is a more important factor.

OBJECTIVES: The authors hypothesized that in children with cardiovascular disease, higher CVP predicts lower estimated glomerular filtration rate (eGFR) and worsening renal function (WRF).

METHODS: We performed a single-center cohort study of patients aged 3 months to 21 years with biventricular circulation undergoing cardiac catheterization. Pearson's correlation and linear and Cox regression analyses were performed to determine associations with eGFR at the time of catheterization and WFR within 180 days …

An Uncommon Culprit: Trapezius Dystonia As A Cause Of Thoracic Outlet Syndrome: A Case Report

Faculty, Staff and Students Publications

Thoracic outlet syndrome (TOS) results from compression of the neurovascular bundle in the thoracic outlet. Several etiologies can contribute to the development of thoracic outlet syndrome, including both congenital and acquired causes. Historically, trapezius pathology has not been considered a cause of TOS; however, here we report a patient with neurogenic TOS plus ipsilateral trapezius hypertonicity and hypertrophy who had significant symptomatic improvement following botulinum toxin injections to trapezius.

Bile Acids Differentially Regulate Longitudinal Smooth Muscle Contractility In Everted Mouse Ileum, Geoffrey A Preidis

Faculty, Staff and Students Publications

Bile acids regulate gastrointestinal motility by mechanisms that are poorly understood. Standard isolated tissue bath assays might not recapitulate in vivo physiology if contractile responses to certain bile acids require direct application to the intestinal mucosa. We sought to determine the feasibility of quantifying longitudinal smooth muscle contractile responses to bile acids from intact segments of everted mouse ileum. Ileum from adult female C57BL/6J mice was isolated, gently everted over a notched metal rod, and mounted in tissue baths. Individual bile acids and agonists of bile acid receptors were added to the baths, and longitudinal smooth muscle contractile responses were …

Defending The Security Of The Mind: A Mail Survey Of Thought-Reform Literacy In South Dakota, Dustin Rozario Steinhagen

Masters Theses & Doctoral Dissertations

Thought reform – also known as brainwashing or psychological manipulation – is a profound threat to the security of the human mind. This complex form of social engineering is associated with terrorist movements, domestic abuse, destructive cults, and many other forms of totalitarianism present in society (Stein, 2017). Thought reform can result in various harms that range in severity depending on each person’s individual experience (Lalich & Tobias, 2006; Stein, 2017). The work of security and privacy professionals inherently concerns psychological manipulation – thought reform often occurs over the internet (Hassan & Shah, 2019), most data breaches occur due to …

Exploring Performance-Based Contracts: A Good Option To Address Long-Term Road Maintenance In California?, Maria Calahorra-Jimenez, Richard Poythress

Mineta Transportation Institute

Performance-based contracts (PBCs) used in road maintenance provide flexibility for considering new materials, design, and technology to achieve predetermined performance targets. Several states in the U.S. have already used these types of contracts in road maintenance, and their experience can inform the use of PBCs in California. The objectives of this research are twofold. First, identify the benefits and challenges of PBCs compared to traditional contracts. Second, explore the main aspects of PBCs implementation for road maintenance and relate them to California's context. To this end, deductive-inductive content analysis was conducted on 84 peer-reviewed articles published between 1998 and 2023. …

A Study Of Learnability In Software As Perceived By Practitioners In User Experience And Learning Design Professions, Courtney N. Miller

STEMPS Theses & Dissertations

In the technology space, there are many factors that contribute to the marketability of software, including pricing and overall usefulness of the product (Jayathilaka, 2021). Many factors contribute to how usable a software is, including satisfaction, error prevention, memorability, efficiency, and learnability (Nielsen, 1994b). Learnability is one factor that may be affected or addressed by both user experience (UX) and learning design (LD) professional groups. While both fields address learnability, very few studies have been conducted to look at the UX interpretation of learnability as it relates to the LD interpretation (Elliott et al., 2002; Li et al., 2023). This …

A Portable Numerical Library For The Calculation Of Multi-Dimensional Integrals, Ioannis Sakiotis

Computer Science Theses & Dissertations

Multi-dimensional numerical integration is a prevalent task in physics and other scientific fields, e.g., in the simulation of particle-beam dynamics and Bayesian parameter estimation. Scientific computing applications that simulate complex phenomena may require the solution to numerous multi-variate integrals. However, functions that have features such as sharp peaks or oscillations in high dimensional spaces, can result in an exorbitant number of computations. For many cases, convergence to accurate results in a reasonable amount of time is infeasible with existing numerical libraries. One approach towards making multi-dimensional integration viable is to parallelize existing algorithms. No commonly available algorithms or libraries exist …

Use Of Cobalt(Iii) And Copper(Ii) Complexes With Thiosemicarbazone Ligands And Berberine Chloride As Anti-Cancer Agents Against Triple Negative Breast Cancer, Duaa Rashad Alajroush

Chemistry & Biochemistry Theses & Dissertations

It is a worrying fact that chemotherapeutic options for treating triple negative breast cancer are limited in nature, including the use of inorganic pharmaceuticals such as cisplatin and its analogues. It has been reported that cisplatin has undesirable side effects when used as a chemotherapeutic drug. As such, there is a need to use non-platinum-containing complexes as chemotherapeutic agents. Based on that issue, it has been reported by our research group and others that cobalt- and copper-containing complexes have shown great potential in anti-cancer properties when compared to cisplatin. In this research project, the cytotoxic effects of the following complexes: …

Adopt: An Environmentally-Friendly System For Alerting Drivers To Occluded Pedestrians Traffic, Abrar Abdulrahman Alali

Computer Science Theses & Dissertations

The emergence of sensing technologies and vehicular communications has brought significant opportunities for enhancing pedestrian safety on city streets. However, existing solutions rely on costly technologies such as computer vision and trajectory prediction to detect crossing pedestrians, while they have limits in detecting pedestrians who are occluded by parked cars. Despite the presence of collaborative perception by surrounding vehicles and infrastructure, there is a notable absence of incorporating existing parked cars themselves due to their insufficiency in detecting pedestrians and communicating with other cars while they are turned off. Furthermore, accommodating pedestrians on streets has been linked to an additional …

A Microservices Approach To Electroencephalography Research In The Public Cloud, Bathsheba Farrow

However, those who report meeting physical activity guidelines express higher rates of health-related quality of life. Largely, the research examining the physical activity behaviors and perspectives of blind and visually impaired adults have been survey studies leaving a rich description of their physical activity experiences unexplored. The overall aim of this project was to engage with blind or visually impaired women to understand their experiences accessing and participating in physical activity, …

Contributions To Nonparametric Testing In Clustered Data, Hasika Kalani Wickrama Senevirathne

Mathematics & Statistics Theses & Dissertations

Clustered data refers to a specific kind of correlated data where units within the same cluster are correlated while units from different clusters are independent. The number of units in each cluster, known as the cluster size, can be associated with the cluster’s outcome. This is known as the informative cluster size (ICS) and affects the inference drawn from clustered data. Recently, a hypothesis testing method has been developed to detect the presence of ICS. However, considering ICS alone may not be sufficient when comparing outcomes across multiple groups of units within clustered data. The size of a group within …

Coherent Backscattering Under Conditions Of Electromagnetically Induced Transparency In Ultracold Rubidium, Joshua D. Carter

Physics Theses & Dissertations

This dissertation presents experimental results of coherent backscattering of light in an ultracold ensemble of rubidium atoms confined in a magneto optical trap under conditions of electromagnetically induced transparency (EIT) in a cascade-type system. Electromagnetically induced transparency was investigated experimentally in both a counterpropagating and orthogonal laser geometry and compared to theory. The experimental results were largely in good agreement with theory. Coherent backscattering was then measured with and without an EIT control field present to investigate the modification, if any, that EIT has on the enhancement of the coherent backscattering cone. The results indicated that the electromagnetically induced transparency …

Decriminalizing Academia: Black First-Generation Community College Students In Unsatisfactory Academic Standing, Gerome Maurice Bell, Jr.

Educational Leadership & Workforce Development Theses & Dissertations

Community colleges serve as critical access points to higher education for Black students. However, current outcomes suggest that Black students are not being properly served in America’s community colleges. Although well-meaning institutional leaders often create policies and programs aimed at improving success rates for students from marginalized backgrounds, too often, the voices of those directly impacted by the policy are not considered. Consequently, little is known about the lived experiences of Black first-generation community college students, especially those in unsatisfactory academic standing. The purpose of this transcendental phenomenological study was to explore the lived experiences of Black first-generation students on …

Prisons Of The Imagination: Carceral Ideology And Race In Science Fiction, Daniel Allen Avant Blachman

Institute for the Humanities Theses

Popular science fiction film and television media commonly deploy narratives and images of prisons and policing, and these discourses in turn are inseparable from racial formations. At the same time, many fans and theorists view science fiction as a genre with immense potential for offering critical consideration of the difference between the fictional and the real world. This thesis examines a range of case studies from popular film and television exemplifying this tension between the perceived generative critical potential of science fiction media and apparent tendency of popular media productions to nearly always fall back on well-worn white supremacist, patriarchal, …

Streaminghub - A Realtime Biosignal Processing Framework For Lab Scale Experimentation, Yasith Jayawardana

Computer Science Theses & Dissertations

In human subjects research, biosignals such as eye movements, heart rate, and brain activity, are often collected and analyzed to find patterns with tangible real-world implications. Modern advancements in technology have sparked interest towards analyzing biosignals in realtime. When developing such algorithms, one may expect to find free, open-source tools that provide easy access to live, recorded, and simulated data streams. Yet, biosignal interfaces are often vendor-specific, making cross-vendor biosignal streaming non-trivial. Likewise, reading biosignal datasets is also non-trivial, as their content may be arranged quite differently.

To combat this divide, we provide the scientific community with a realtime biosignal …

The Impact Of Emotional Impulsivity On Emotion Regulation And Internalizing Disorders: Competing Latent Path Models, Alicia L. Milam

Psychology Theses & Dissertations

Emotion regulation has been identified as a transdiagnostic risk factor in internalizing disorders. Previous literature has attempted to classify regulatory strategies by their temporal and functional characteristics to determine how to best implement emotion regulation interventions. However, these frameworks occasionally conflict, particularly in the presence of factors impacting regulatory strategy selection such as emotional impulsivity. This project examined competing theoretical models of emotion regulation strategy classification as related to internalizing psychopathology as well as explore the association between emotional impulsivity, regulatory classification and internalizing psychopathology. A community sample of 783 adults recruited through Amazon MTurk completed online questionnaires related to …

A Comparison Of Specialized And General Orientation Courses For Community College Students, Heather R. Sorrell

Educational Leadership & Workforce Development Theses & Dissertations

This study examined the effect of specialized orientation courses on community college student academic achievement and retention. The study utilized a quantitative design and compared the outcomes of specialized orientation courses to a more generalized orientation course. Due to the lack of previous research, there was little to suggest either a positive or a negative influence on student success measures for a targeted, specialized version of orientation courses. The study found that achievement outcomes did not differ between specialized orientation courses and general orientation courses. The study did find retention differences based on the type of orientation course completed. Students …
