``Set it and forget it'' is a common practice with automatic irrigation systems and can lead to excessive irrigation, unhealthy root systems, and water waste. The Water Dogs program in Nebraska focuses on educating Extension Master Gardener volunteers (EMGVs). The goal was to increase their understanding of turfgrass water needs, efficient irrigation methods, and soil health management practices, and to promote greater engagement of EMGVs with homeowner audiences to share and demonstrate the knowledge gained and practices learned through ``Neighbor-to-Neighbor'' workshops. The overall goal is to conserve water and improve soil and plant health.

Prehospital Flumazenil: Five-Year Review Of Use, Indications, Outcomes, And Adverse Events In Suspected Benzodiazepine Overdose, Cameron G. Hanson, Bryan P. Beaver, Eric Frantz, Thomas Dunn, Stephen Thornton, Isabel Cava, Ryan C. Jacobsen

Student Publications

Introduction: Historically, flumazenil was employed as both a diagnostic aid in unresponsive patients and as an antidote for suspected benzodiazepine overdose in both emergency departments and out-of-hospital settings. However, its prehospital application has been historically constrained by long-standing concerns regarding adverse events, leading many emergency medical service (EMS) systems to restrict or avoid its use. The use of flumazenil in the prehospital setting remains underreported in the literature, despite its inclusion in the treatment protocols of various EMS agencies. We conducted a descriptive analysis of the use of flumazenil by EMS in the out-of-hospital setting across the state of Kansas …

The Impact Of Built-Environment Walkability On Obesity Among Women In Pakistan: A Cross-Sectional Analysis Using Demographic Health Surveys (Dhs) Data, Areej Arshad

Theses

Pakistan is the fifth most populous country in the world, with a population of over 247 million people in 2023. According to the World Health Organization, 23% of Pakistan’s population is obese, with higher prevalence among women (26%) compared to men (19.9%). Recent research in high-income countries has identified built-environment as an important factor impacting physical activity, as well as health outcomes like obesity rates. However, work linking built-environment and health outcomes is scattered for low- and middle- income countries. This study, therefore, aimed to construct a consistent and simple built-environment walkability score for Pakistan using Demographic Health Surveys (DHS) …

Ai-Driven Prognostics For Pem Fuel Cells Using Optimized Machine Learning And Deep Learning Models For Accurate Lifetime Prediction, Walid Abdullah, Reda Mohamed, Ibrahim Alrashdi, Mohamed Abdel-Basset, Mahmoud Mahdi

Sustainable Machine Intelligence Journal

Predicting how long proton exchange membrane (PEM) fuel cells will last is important for making them more reliable and reducing maintenance costs. However, most existing methods struggle to understand complex patterns in the data, leading to less accurate predictions. This paper introduces two new models to improve predictions. The first model, attention-based long short-term memory (ALSTM), is based on LSTM networks with an attention mechanism. This helps the model focus on the most important time steps in the data, making predictions more accurate. The second model, B-Ridge-JADE, selects the most useful features from the data using an adaptive differential evolution …

Measuring Maintainable Income Under Natural Capital Depletion: A Dynamic Sustainability-Weighted Cost Of Capital Framework, Khaled Aldhaferi

Journal of King Abdulaziz University: Economics and Administration

Sustainability reporting has improved the visibility of climate, resource, and safety risks, but it still does not provide a measurement mechanism for separating maintainable operating surplus from income generated by depleting finite natural capital. This paper develops Dynamic Sustainability-Weighted Cost of Capital (Dynamic SWACC) as a governed shadow-accounting architecture for estimating sustainability-adjusted maintainable income. The framework begins from the Hicksian capital-maintenance view of income and the El-Serafy user-cost method, derives the user-cost charge from a finite-horizon operating-surplus annuity, and endogenizes the discount rate through auditable state variables: reserve-life constraint intensity, carbon-budget utilization, and operational safety risk. The developed contribution extends …

Examining The Relationship Between Transport Infrastructure Quality And Co2 Emissions: Evidence From South And Southeast Asia, Badr A. Alreshidi

Journal of King Abdulaziz University: Economics and Administration

Transport infrastructure quality plays a critical role in supporting economic activity and facilitating the movement of goods and people. However, improvements in transport systems may also generate environmental consequences through increased emissions. The aim of this paper is to examine the impact of the transport infrastructure quality on CO₂ emissions in fifteen South and Southeast Asian countries during the period from 2013 to 2019. An OLS regression model of panel data was used in order to evaluate the influence of the transport infrastructure quality (road, rail, air, port) on CO₂ emissions. The results of the empirical analysis demonstrate …

Empowering Communication And Understanding In Healthcare Relationships With Human-Centered Ai, Songyun Tao

Dartmouth College Ph.D Dissertations

Healthcare communication depends not only on what information is available, but on how it is interpreted, communicated, and acted upon across different roles. AI can support these processes by summarizing, transforming, and organizing information, but it can also change what becomes visible, who is expected to act, and where responsibility resides.

This dissertation examines how human-centered AI can support communication and understanding across healthcare relationships through three independently developed systems. MusicalPT supports self--body communication in physical rehabilitation through adaptive musical feedback. CareInsights supports communication among professional caregivers in long-term dementia care by preserving and surfacing person-specific context across shifts. Family …

Neurodivergent Peer Tutoring And Anti-Ableism: Two High Schoolers’ Lived Experiences While Working In A Neurodiversity-Based Writing Center, Daniel S. Harrison

The Writing Center Journal

Neurodivergence is naturally present in the writing center and most often recognized by labels like ADHD, autism, OCD, dyslexia, and so on. However, neurodivergent voices in writing center scholarship have been few and far between in postsecondary institutions (Babcock, 2017; Batt, 2018; Kleinfeld, 2023), and in the secondary writing center even less so. Therefore, the purpose of this multiple case study was to explore the personal, relational, and formative aspects of the lived experiences of two neurodivergent students through a critical disability theory lens as they provided writing consultations to their neurodivergent peers in a Mid-Atlantic, independent special education school. …

Radiation Testing And Failure Analysis Of A Complex Heterogeneous Soc, Garrett Smith

Theses and Dissertations

Heterogeneous System on Chips (SoCs) provide a robust platform that can flexibly handle different applications. Their small form factor and low power consumption for their performance have made SoCs an attractive option for space applications. However, SoCs are sensitive to the ionizing radiation found in space. We need to understand how an SoC will behave in the high radiation found in space. This requires us to perform radiation testing of the SoCs on Earth to understand their behavior. The radiation testing and analysis of a heterogeneous SoC is complex as it contains multiple different processing cores, memories, and other system …

Machine Learning Integrated Designing And Screening Of 8-Hydroxyquinoline Based Metallo-Beta-Lactamase Inhibitors, Anthony M. Baudino, Kari Stone

Chemistry Department Faculty Articles

The rapid emergence of metallo-b-lactamase-mediated antibiotic resistance has created an urgent need for new inhibitor discovery strategies. In this work, a machine-learning-guided workflow was developed to generate and prioritize potential inhibitors targeting NDM-1. A SMILES-based variational autoencoder was first pretrained on a broad molecular dataset to learn general chemical syntax and latent molecular representations. The model was then fine-tuned on an 8-hydroxyquinoline-enriched dataset to bias molecular generation toward zinc-binding chemical space relevant to metallo-β-lactamase inhibition. Generated compounds were processed through structural filtering and docking-based evaluation to create training data for downstream predictive modeling. Molecular fingerprints and physicochemical descriptors were then …

A Fuzzy–Neutrosophic Suitability Index For Selecting An Appropriate Reasoning Model Under Vagueness, Incompleteness, And Conflict, Nada A. Nabeeh, Ahmed Samy

Neutrosophic Systems with Applications

Fuzzy reasoning and neutrosophic reasoning are both used to handle uncertainty, but they are not intended for the same uncertainty structure. Fuzzy reasoning is suitable when uncertainty appears mainly as gradual vagueness, where a value may belong to a concept such as ``high risk'' or ``good performance'' to a certain degree. In this case, a membership value is often sufficient. Neutrosophic reasoning is more suitable when the problem also contains incomplete information, undecided evidence, or conflict between sources. In such cases, one membership degree may be too limited because it cannot represent support, rejection, and indeterminacy separately. This study introduces …

Foundations Of Neutrosophic N-Semirings Theory And Structural Properties, Raja Muhammad Hashim, Muhammad Gulistan, Muhammad Shahzad

Neutrosophic Systems with Applications
