Data-Driven Prediction Of Superconducting Critical Temperature: A Linear And Regularized Linear Modeling Approach, Dipok Deb

Data Science and Data Mining

This study adopts a data-driven approach to estimate the critical temperature of superconducting materials using linear machine learning models. A comprehensive dataset derived from material physico-chemical properties was analyzed after systematic preprocessing and standardization. Three linear modeling strategies—Linear Regression, Ridge Regression, and Linear Regression with Subset Selection—were developed and evaluated using standard regression performance metrics. The findings demonstrate that both basic and regularized linear models can effectively capture the relationship between material features and superconducting behavior, offering robust and interpretable predictions. While feature selection enhances model transparency, it comes with a modest reduction in predictive capability. Overall, this work emphasizes …

A Comparative Performance Study Of Webp Compression In A Cryptographic–Steganographic Pipeline For Secure E-Commerce Transactions, Esther Abeson Nasara, Moses Timothy, Agushaka J. Ovre, Taofeekat Tosin Salau-Ibrahim

Al-Bahir

The expeditious growth of electronic commerce (e-commerce) fundamentally transformed business operations and consumer behavior by enabling businesses to reach a global market, streamline supply chains, and provide personalized shopping experiences. This shift necessitated reliable security measures to protect sensitive information during online transactions. However, existing approaches that combined encryption, steganography, and conventional compression techniques such as DCT and autoencoders were limited in preserving image quality and computational efficiency. To address this gap, the objective of this study was to integrate WebP compression into the cryptographic–steganographic pipeline in order to improve image quality, ensure payload integrity, and achieve efficiency suitable for …

When Ownership Meets Licensing–New Normative Expectations And The Need For Nft Categorization: All Your Projects “Are” Belong To Us, Charles Belle

UC Law Science and Technology Journal

The current treatment of all NFTs in legal scholarship as identical digital assets fundamentally misunderstands their varied applications and the new normative expectations they create. The Moonbirds controversy of 2022, where a creator’s unilateral license change affected nearly 20,000 token holders, exemplifies the crisis: token holders believed they owned digital assets that could be controlled and commercialized, but existing copyright frameworks treat NFTs merely as licenses subject to creator discretion. Picture for Profile (PFP) Projects—community-based NFT collections involving thousands of tokens often with governance and commercial rights—combine concepts of possession, community governance, and commercialization in ways that challenge traditional intellectual …

Codifying Command: Integrating Ai Into Corporate Boards, Kennedy Kelley

UC Law Science and Technology Journal

Corporate law in the United States requires that boards of directors be composed of human individuals, prohibiting artificial intelligence (AI) from serving in a directorial role. Statutes such as Delaware General Corporation Law §141(b) mandate that directors be natural persons, while fiduciary duty doctrines, liability structures, and regulatory frameworks presuppose human oversight and accountability. This paper argues that such legal constraints are increasingly outdated and should be reformed to permit AI to serve as a board member, alongside natural persons, with full decisionmaking authority. As AI systems become more capable of complex, datadriven reasoning, corporations should not be barred from …

Initial Validation Of The Teleoperator-Avatar Robot Interaction Scale (Tarx), Nicholas Bowman, Rio Harper, Jaime Banks

Media Studies - All Scholarship

Extant work on human-machine relations indicates humans experience variably social relations with machines. However, there is yet no systematic framework for considering the potential sociality of relations between teleoperators and controlled robots, in addition to their functional associations. We bridge that gap by initially validating a proposed-butuntested measurement model of teleoperator/avatarrobot interaction (the TARX scale) inspired by gamebased player-avatar relations. In a lab-based study of human operators’ subjective experiences in remotecontrolling a robotic arm, we find support for the hypothesized factor structure comprising four dimensions: Relational closeness, anthropomorphic autonomy, critical concern, and sense of control. Results demonstrate the coherence of …

Bridging The Gap: A Systematic Review Of Cyber Conflict Forecasting Models And The Case For Ai-Driven Dynamic Frameworks, Salim Arfaoui, Youssef Harrath, Omar El-Gayar

Research & Publications

Cyber conflict forecasting remains constrained by static models that overlook the integration of geopolitical context with technical indicators. This systematic literature review examines 58 studies (2010–2025) using PRISMA guidelines and an InputProcess-Output framework to classify approaches and identify key gaps. Quantitative methods dominate (67%), yet only 14% incorporate geopolitical variables, despite the political nature of cyber conflict. Major limitations include adversarial adaptation blindness (85% assume static behavior), coarse temporal granularity (72% use daily+ intervals), lack of uncertainty quantification (75%), and minimal modeling of cross-domain escalation (92% cyber-only focus). Strategic forecasting is rare, with just 14% providing long-term insights and 16% …

Private Money: Stablecoins, Bitcoin, And The Genius Act, Henry H. Perritt Jr.

UC Law Science and Technology Journal

Cryptocurrency has been legalized in the United States. The 2025 GENIUS Act provides a sensible regulatory framework for cryptocurrency as a medium of exchange while avoiding predicted monetary chaos. The Act correctly distinguishes between volatile fiat cryptocurrencies like Bitcoin, which are unsuitable as payment mechanisms, and stablecoins backed by traditional currencies and reserves.

Historical analysis spanning American monetary systems from the “free banking era” before 1860 through modern digital payments demonstrates that private money has long coexisted with government currency but requires appropriate regulation to prevent bank runs, fraud, and monetary instability. The GENIUS Act addresses key cryptocurrency risks—technological failures, …

Predicting The Long-Term Evolution Of A Barrier Spit In A Changing Climate: A Case Study In Rhode Island, Napatree Point, Alexa Leone, Annette Grilli, Bryan Oakley, Bas Huisman, Ap Van Dongeren, Johan Reyns, Dano Roelvink

Ocean Engineering Faculty Publications

Shoreline recession poses a substantial threat to coastal communities. This study evaluates the long-term viability of the undeveloped Napatree barrier spit in Rhode Island, which provides critical habitat for both flora and fauna, including endangered species, and protects the small town of Westerly from the direct impact of tropical storms and Nor’easters. While the Napatree shoreline has been morphologically stable in recent decades (1970–present), historical periods of higher storm frequency and intensity had resulted in significant changes, including spit splitting and significant transgression. We use the one-line numerical model ShorelineS to assess long-term changes in the position of the Napatree …

Children’s Nutrition Research Center Staff Publications

Background: Cardiorespiratory fitness is an integrative measure of cardiometabolic health and predictor of survival, yet little is known about its molecular underpinnings. Small molecule metabolites and lipids are increasingly recognized as exercise-stimulated signaling molecules and candidate molecular transducers of cardiorespiratory fitness.

Methods: We performed nontargeted liquid chromatography mass spectrometry-based plasma metabolomics in 654 participants (mean age, 35 years; 55% women) from the HERITAGE Family Study (Health, Risk Factors, Exercise Training, and Genetics) who had cardiorespiratory fitness (maximal oxygen uptake [VO2max]) measured by cardiopulmonary exercise testing and underwent 20 weeks of supervised endurance training. Metabolite-VO2max relationships were assessed using linear regression …

A Caregiver’S Perspective Of Caring For Children With Intellectual Disabilities, Lajoy Johnson Law

Walden Dissertations and Doctoral Studies

Current estimates reported by the National Institute of Health suggest that between 1.4 and 2.2 million children in the United States have some form of intellectual disability. These children need caregivers, yet in the literature there is a lack of studies focusing on the experiences of caregivers raising children with intellectual disabilities. Further, there is a lack of public policies and programs for Washington, D.C. caregivers. The purpose of this general qualitative study was to explore the lived experiences of these caregivers in Washington, D.C. and to identify what policies, programs, and services are needed to support them. Guided by …

Female Military Sexual Trauma Survivors’ Experiences With Seeking Treatment From The Veterans Health Administration, Sherry Sophia Bolden Rivers

Walden Dissertations and Doctoral Studies

The Veterans Health Administration (VHA) provides free healthcare related to those who have experienced military sexual trauma (MST); however, many female veterans either go without or delay accessing such care. This generic qualitative study was conducted to answer the research question about the reasons behind female veterans’ decisions to seek or not seek VHA services following the experiences of MST. The framework for this study was Wollstonecraft’s feminist theory. An additional question was how, if at all, the stigma of MST and the military’s male-dominated culture play a role in the reporting of these incidents. Data were collected through semistructured …

Factors Affecting The Level Of Grief Experienced By Men Whose Female Partner Died In The United States, Keona C. Lee

Walden Dissertations and Doctoral Studies

Grief is an emotional reaction to the loss of a loved one through death. Although grief is a universal human experience, its perspective is unique, and research has often ignored the varied experiences of racial/ethnic and cultural groups, particularly men of color in the United States. The purpose of this quantitative study was to measure the level of grief experienced by men whose female partner died and to determine whether ethnicity, having a prior mental health diagnosis, social support, and traumatic or anticipated loss significantly impacted their level of grief. The study was guided by the social-ecological model to explain …

Exploring The Impact Of Antidiscrimination Laws On Child-Welfare Workers Working With Lgbtq Foster Youth, Heather Kesterson

Walden Dissertations and Doctoral Studies

Lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ) youth are overrepresented in the foster care system and have unique needs compared to their peers. In the state of Virginia, there is an antidiscrimination policy that protects LGBTQ foster youth; however, it is unclear how this impacts child welfare workers. Past literature has explored the needs of LGBTQ youth, the experiences of foster parents, and policy implications, but not the impact of antidiscrimination laws on child welfare workers. The purpose of this generic qualitative study was to explore the understanding of child welfare workers’ knowledge, integration, training, and implications of Virginia’s antidiscrimination …

Relational Healing: Survivors Of Sex Trafficking And Their Experiences Of Connection, Disconnection, And Growth, Claudia G. Interiano-Shiverdecker, Devon E. Romero, David J. Thompson, John J. J. S. Harrichand

Department of Counseling Scholarship and Creative Works

In this interpretive phenomenological analysis, we interviewed 10 women to make meaning of their lived experiences of sex trafficking and mental health challenges and how relational dynamics influenced their healing and sense of self. Our analysis revealed four themes: (a) central relational paradox, which described internalized shame and mistrust due to relational ruptures as a result of trauma and inadequate trauma-informed care; (b) disconnection and disempowerment, attending to survivor protective withdrawal mechanisms and how counselor misattunement created cycles of disconnection and invalidation; (c) fluid expertise, where survivors emphasized that healing occurred when counselors embraced a collaborative, respectful stance, honoring client …

Latin American Refugees To The U.S. Experience More Discrimination Than Refugees From Other Regions, Sobia Mushtaq, Janet M. Wilmoth

Population Health Research Brief Series

Discrimination is a serious challenge for refugees trying to rebuild their lives in new countries. This data slice presents findings from the 2022 Annual Survey of Refugees (ASR), a nationally representative survey of refugees who arrived in the United States between 2017 and 2021 (N=1,364). The probability of experiencing discrimination was substantially higher among refugees from Latin America compared to other origin regions. Latin American refugees have a 62.4% probability of experiencing discrimination, compared to 12.6% for Southeast Asian refugees. The findings suggest that service providers and policymakers should not assume that all refugees face the same challenges.

The Determinants Of Internal Fraud Using The Fraud Hexagon Framework: A Study Of The Banking Sector Listed On The Indonesia Stock Exchange, Annisa Zikria, Srihadi Winarningsih, Faoziah Ulfah Fatmawati

Journal of Accounting Auditing and Business

This study examines the determinants of internal fraud in Indonesian listed banks by applying the Fraud Hexagon framework (pressure, opportunity, rationalization, capability, arrogance, and collusion) to the banking sector on the Indonesia Stock Exchange (IDX) over 2020–2024. Internal fraud is operationalised as the number of internal fraud cases disclosed in each bank’s annual report during the study period. The analysis uses a balanced panel of 23 banks across five years (total 115 observations) and estimates a panel least squares model with cross-section fixed effects to control for time-invariant heterogeneity across banks. Pressure is proxied by the non-performing loan ratio, opportunity …

Knowledge And Perception Of Human Milk Donation Among Pregnant, Lactating, And Postpartum Women In Rochester, Ny, And Near Hmbana Milk Banks, Samantha Allen

Theses

Human milk banks provide pasteurized donor milk for premature infants whose mothers are unable to produce sufficient amounts of milk, offering critical nutritional and immunological benefits for this high-risk population.1–4 Although 28 HMBANA-accredited milk banks operate in the United States, none are located within 4.5 hours of Rochester, NY. This study examined the knowledge and perceptions of human milk bank donation among pregnant, lactating, and postpartum women in Rochester, NY, and in communities near HMBANA-affiliated milk banks, and assessed if there is a correlation regarding the proximity of milk banks.  A cross-sectional study design was used, and participants completed a …

Development And Characterization Of Compression-Molded Chitosan Composite Films Reinforced With Silica And Titania Fillers, Bhuvaneswari Koti, Vuong Do, Yanika Schneider, Vimal Viswanathan

Faculty Research, Scholarly, and Creative Activity

This study investigates the development of biodegradable chitosan-based films as a sustainable alternative to conventional non-biodegradable food packaging materials. Chitosan, a naturally occurring polymer, possesses inherent film-forming ability and biodegradability; however, its limited mechanical and thermal properties constrain its practical applications. In this work, chitosan films were fabricated via compression molding, and their thermo-mechanical performance was systematically evaluated. The incorporation of fillers, such as titanium dioxide and silica, resulted in a 50% enhancement in tensile strength and an 86% improvement in flexibility. Further optimization of dual-filler compositions led to an additional 45% increase in elasticity, demonstrating the potential of synergistic …

Acoustic Analysis Of Prosodic Speech Pause In Autistic And Neurotypical Adults, Rachel Johnson

Theses and Dissertations

The purpose of this study is to examine prosodic speech pause across two groups: neurotypical and autistic young adults. Conversational speech samples were collected from 11 neurotypical and 11 autistic young adults between the ages of 18 and 26. Speech samples were subsequently transcribed and analyzed using Praat Software. The boundaries of between- and within-utterance pauses were identified, as well as acoustically determining if the pause was filled, silent, or a combination of both. Results found a significant difference in the frequency of pauses as a function of location, pause type, and neurological status. As expected, combination pauses were the …

An Eye For An Eye And A Smile For A Smile: Examining Aggressive And Supportive Behavioral Alignment Among Taiwanese Adolescence Who Play Video Games, Nicholas Bowman, Chrissy Cook, Chingching Chang

Media Studies - All Scholarship

The social dynamics of video games, especially those played online, are one of the primary motivators for gaming. Unfortunately, while there are numerous benefits to online gaming, there is also potentially harmful toxic and aggressive behavior. Prior research has investigated toxicity, but most studies rely on convenience samples, typically from WEIRD populations. The current study extends this scholarship with a nationally representative sample of Taiwanese adolescents who are frequent gamers, (a) quantifying their experiences with aggressive and supportive behaviors in games and (b) investigating personological-level variables that might explain reciprocating (referred to as “behavioral alignment”). Key findings were (1) aggressive …

Tectonic Implications Of Transitional Melting Regimes From Petrological, Geochronological, And Compositional Characterization Of The Ophiolitic Seventymile Terrane, Alaska, Usa, Erin Todd, Johnathan Saul Caine, Michael Bizimis, Andrew R.C. Kylander-Clark, Robert Reece Hammond, Alicja Wypych

Faculty Publications

New geochemical, U-Pb geochronology, and Sr-Nd-Hf isotope data provide evidence for the tectonic evolution of the Seventymile terrane in interior Alaska, USA. Ultramafic and mafic rocks of the Seventymile terrane are thought to represent components of a dismembered ophiolite and provide unique constraints on regional terrane evolution and accretion. The Seventymile ophiolite represents fragments of the Devonian to Permian Slide Mountain Ocean (SMO) that separated allochthonous and parautochthonous continental fragments of western North America. It now occurs as multiple thrust sheets containing Permian mafic and ultramafic rocks overlying and/or possibly imbricated with amphibolite-facies supracrustal rocks of allochthonous Yukon-Tanana terrane and …
