The Invariantring Package For Macaulay2, Luigi Ferraro, Federico Galetto, Francesca Gandini, Hang Huang, Matthew Mastroeni, Xianglong Ni Mar 2024

The Invariantring Package For Macaulay2, Luigi Ferraro, Federico Galetto, Francesca Gandini, Hang Huang, Matthew Mastroeni, Xianglong Ni

School of Mathematical & Statistical Sciences Faculty Publications

We describe a significant update to the existing InvariantRing package for Macaulay2. In addition to expanding and improving the methods of the existing package for actions of finite groups, the updated package adds functionality for computing invariants of diagonal actions of tori and finite abelian groups, as well as invariants of arbitrary linearly reductive group actions. The implementation of the package has been completely overhauled with the aim of serving as a unified resource for invariant theory computations in Macaulay2.

Separation And Relative Quasiconvexity Criteria For Relatively Geometric Actions, Eduard Einstein Mar 2024

Separation And Relative Quasiconvexity Criteria For Relatively Geometric Actions, Eduard Einstein

Mathematics & Statistics Faculty Works

Bowditch characterized relative hyperbolicity in terms of group actions on fine hyperbolic graphs with finitely many edge orbits and finite edge stabilizers. In this paper, we define generalized fine actions on hyperbolic graphs, in which the peripheral subgroups are allowed to stabilize finite subgraphs rather than stabilizing a point. Generalized fine actions are useful for studying groups that act relatively geometrically on a CAT(0) cube complex, which were recently defined by the first two authors. Specifically, we show that any group acting relatively geometrically on a CAT(0) cube complex admits a generalized fine action on the one-skeleton of the cube …

Influence Of Professional Learning Communities On Teachers’ Stress: A Case Study, Jason Young Mar 2024

Influence Of Professional Learning Communities On Teachers’ Stress: A Case Study, Jason Young

Student Theses and Dissertations

Teachers are opting to exit the profession at an unprecedented rate. This trend has led to hiring shortages and the state department lowering licensure standards in the State of Arkansas. The increase in job demands placed on teachers has led to elevated stress levels among educators, ultimately driving them to abandon the field altogether. The current qualitative case study was to explore teachers’ perspectives on the influence professional learning communities (PLCs) can have in reducing job-related stress. The job-demands resource (JD-R) model, which explains how the job-demands cause teacher stress and make it possible to understand teachers’ perceptions of PLCs …

On The Subelliptic And Subparabolic Infinity Laplacian In Grushin-Type Spaces, Zachary Forrest Mar 2024

On The Subelliptic And Subparabolic Infinity Laplacian In Grushin-Type Spaces, Zachary Forrest

USF Tampa Graduate Theses and Dissertations

This thesis poses the ∞-Laplace equation in Grushin-type spaces. Grushin-type spaces G are defined by the vector fields which serve as a basis for their tangent spaces; by weighting the canonical (Euclidean) directional vectors {∂/∂xi}ni=1 by functions ρi that obey certain technical assumptions, we produce a class of metric spaces in which certain directions may not be accessible at all points in the space. We prove the existence and uniqueness of viscosity solutions to both Dirichlet problems and Cauchy-Dirichlet problems involving the∞-Laplacian over bounded Grushin-type domains. The main tool in proving uniqueness of …

Problem-Solving In The Preparation Of Teachers For Agricultural Education: A Mixed Methods Study Investigating The Effect Of Metacognitive Awareness And Cognitive Ability On Students Enrolled In An Introductory Agricultural Mechanics Course, Whitney Figland

LSU Doctoral Dissertations

Cognitive and metacognitive ability have been identified as a critical factor that influences individuals to successfully problem-solve. However, recent research has indicated that students do not have the necessary 21st-century skills to be successful in the workplace. This issue has been confounded by the lack of school-based agricultural education (SBAE) teachers’ limited knowledge regarding effectively teaching decision-making skills and the use of teaching methods that promote problem-solving. Therefore, this study sought to understand the effect that cognitive and metacognitive ability had on the problem-solving of students who are enrolled in an Introduction to Agricultural Mechanics course at Louisiana State University. …

China Maritime Report No. 36: China's T-Agos: The Dongjian Class Ocean Surveillance Ship, Devin Thorne

CMSI China Maritime Reports

Since 2017, the People’s Liberation Army Navy (PLAN) has commissioned a new class of ocean surveillance vessel into its order of battle: the Type 927. Similar in design and function to the U.S. Navy’s Victorious and Impeccable class T-AGOS ships, the Type 927 was introduced to help remedy the PLAN’s longstanding weakness in anti-submarine warfare. The PLAN has likely built six Type 927 ships to date, most based for easy access to the South China Sea. In peacetime, these ships use their towed array sonar to collect acoustic data on foreign submarines and track their movements within and beyond the …

Autophagy and ribonucleoprotein granules, such as P-bodies (PBs) and stress granules, represent vital stress responses to maintain cellular homeostasis. SQSTM1/p62 phase-separated droplets are known to play critical roles in selective autophagy; however, it is unknown whether p62 can exist as another form in addition to its autophagic droplets. Here, we found that, under stress conditions, including proteotoxicity, endotoxicity, and oxidation, autophagic p62 droplets are transformed to a type of enlarged PBs, termed p62-dependent P-bodies (pd-PBs). p62 phase separation is essential for the nucleation of pd-PBs. Mechanistically, pd-PBs are triggered by enhanced p62 droplet formation upon stress stimulation through the interactions …

Community-Centered Early Warning For Outbreaks In Humanitarian Emergencies: Evaluating Community-Based Surveillance For Priority Communicable Diseases Among Internally Displaced Populations In Iraq, Caitlin M. Wolfe Mar 2024

Community-Centered Early Warning For Outbreaks In Humanitarian Emergencies: Evaluating Community-Based Surveillance For Priority Communicable Diseases Among Internally Displaced Populations In Iraq, Caitlin M. Wolfe

USF Tampa Graduate Theses and Dissertations

Background: Community based surveillance (CBS) is the organized and rapid collection of information from health events identified in the community and includes the systematic detection and reporting of events of public health significance. While used globally to enhance the detection of priority diseases, CBS has not been routinely deployed in Iraq, where a once-robust health system has been devastated by decades of war, international sanctions, and large-scale population displacement. During infectious disease outbreaks, it is imperative to quickly detect and isolate suspect cases, investigate confirmed cases, and trace and monitor the contacts of confirmed cases. The COVID-19 pandemic underscored the …

While the rise of large language models (LLMs) has created rich new opportunities to learn about digital technology, many on the margins of this technology struggle to gain and maintain competency due to lexical or conceptual barriers that prevent them from asking appropriate questions. Although there have been many efforts to understand factuality of LLM-created content and ability of LLMs to answer questions, it is not well understood how unclear or nonstandard language queries affect the model outputs. We propose the creation of a dataset that captures questions of digital newcomers and outsiders, utilizing data we have compiled from a …

Characterization Of Oscillatory Response Of Light-Weight Wind Turbine Rotors Under Controlled Gust Pulses, Fernando Ponta, Alayna Farrell, Apurva Baruah, North Yates

Michigan Tech Publications

Given the industry-wide trend of continual increases in the size of utility-scale wind turbines, a point will come where reductions will need to be made in terms of the weight of the turbine’s blades to ensure they can be as long as needed without sacrificing structural stability. One such technique that may be considered is to decrease the material used for the shell and spar cap. While this will solve the weight issue, it creates a new one entirely—less material for the shell and spar cap will in turn create blades that are more flexible than what is currently used. …

Methionyl-Trna Synthetase Synthetic And Proofreading Activities Are Determinants Of Antibiotic Persistence, Whitney N. Wood, Miguel Angel Rubio, Lorenzo Eugenio Leiva, Gregory J. Phillips, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Bacterial antibiotic persistence is a phenomenon where bacteria are exposed to an antibiotic and the majority of the population dies while a small subset enters a low metabolic, persistent, state and are able to survive. Once the antibiotic is removed the persistent population can resuscitate and continue growing. Several different molecular mechanisms and pathways have been implicated in this phenomenon. A common mechanism that may underly bacterial antibiotic persistence is perturbations in protein synthesis. To investigate this mechanism, we characterized four distinct metG mutants for their ability to increase antibiotic persistence. Two metG mutants encode changes near the catalytic site …

Biomarkers For Managing Neurodegenerative Diseases, Lara Cheslow, Adam E. Snook, Scott A. Waldman

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Neurological disorders are the leading cause of cognitive and physical disability worldwide, affecting 15% of the global population. Due to the demographics of aging, the prevalence of neurological disorders, including neurodegenerative diseases, will double over the next two decades. Unfortunately, while available therapies provide symptomatic relief for cognitive and motor impairment, there is an urgent unmet need to develop disease-modifying therapies that slow the rate of pathological progression. In that context, biomarkers could identify at-risk and prodromal patients, monitor disease progression, track responses to therapy, and parse the causality of molecular events to identify novel targets for further clinical investigation. …
