The Geologic History Of The Chehalis Forearc Basin, Washington State, Usa, R. L. Moe, J. Bershaw, L. M. Staisch, A. R. Streig

Geology Faculty Publications and Presentations

The Chehalis basin is located between the Cascade arc and the Coast Range in southwest Washington State. It consists of sedimentary and volcanic rocks deposited throughout the Cenozoic and is underlain by the Siletzia terrane, a thick, large igneous province accreted in the Eocene. Here, we constrain evolution of the Chehalis basin depocenter using isochore maps derived from isostatic gravity anomalies, borehole data, and stratigraphy for several time periods: the Eocene (47.6–36.8 Ma), the Oligocene (36.8–20 Ma), and the Neogene (20–0 Ma). Our results suggest that local subsidence is driven by deformation on faults that bound and intersect the basin. …

Background: The first international clinical standards of care for the gender-diverse population were formulated in the late 1970s. In the last 15 years, multiple subspecialty societies within the United States have developed clinical care guidelines for those with gender dysphoria, including gender-affirming hormone therapy (GAHT) and surgical treatments. To date, there are no pathology- and laboratory medicine-specific recommendations in the United States for the gender-diverse population.

Content: This document outlines pathology- and laboratory medicine-specific recommendations for providing optimal care to the gender-diverse population, with a predominant focus on the adult population. The scope of this document focuses on the following …

Faculty, Staff and Students Publications

Study objectives: Sleep problems are common in children with SYNGAP1-Related Disorder (SYNGAP1-RD). The use of devices that objectively estimate sleep are complicated by co-occurring sensory disorders in this population. We examined the feasibility and validity of wrist actigraphy to examine sleep and rest-activity rhythms (RAR).

Methods: Data from five children with SYNGAP1-RD and 42 typically developing children were analyzed. All children were asked to wear the Actiwatch-2 for 14 continuous days and caregivers were asked to complete a sleep diary and the Children Sleep Health Questionnaire (CSHQ). Parametric (alpha, beta, acrophase, amplitude, up/down mesor, mesor), nonparametric (intradaily variability, interdaily stability, …

Statistical Evaluation Of A New Orleans Historic Rainfall Dataset (1840–1893), Arielle C. Filostrat

LSU Master's Theses

This study evaluates the climatic credibility of a newly identified historical rainfall dataset for New Orleans, Louisiana, spanning 1840–1893. The New Orleans Historical Dataset (NOHD) is compared to a modern observational record from the Audubon rain gauge (1893–2024) to determine whether nineteenth-century rainfall observations are consistent with known precipitation behavior in the region. Establishing the reliability of early records is critical for extending climatological baselines and improving understanding of long-term rainfall variability.

Historical rainfall observations were first evaluated through archival review using the New Orleans Medical and Surgical Journal and other nineteenth-century meteorological records to verify notable rainfall events. Daily …

Improving Neutron Scattering And Fission Modeling With Modern Machine Learning, Karl Daningburg

Theses

We describe the development of a novel emulator for the fission fragment decay code, $\texttt{CGMF}$, which calculates the emission of prompt neutrons and $\gamma$ rays from fission fragments.  The emulator described in this work uses a combination of a noisy emission model and mixture density network to model the neutron and $\gamma$-ray multiplicities and energies.  In this manuscript, we display the power of this type of emulator for not only modeling average prompt fission observables but also correlations between fission fragment initial conditions and these observables, using both neutron-induced and spontaneous fission reactions. We find that neutron ($\gamma$-ray) multiplicities can …

Understanding The Lubrication Mechanisms Of Environmentally Compatible Protic Ionic Liquids, Davis Kipkania Kiboi

Theses

The development of environmentally sustainable lubricants is increasingly important as industries seek to reduce friction, wear, energy losses, and environmental impact. Choline amino acid protic ionic liquids (PILs) have emerged as promising candidates due to their bio-based constituents, tunable molecular structures, and favorable lubrication properties. However, the influence of amino acid structure on their lubrication mechanisms and tribological performance remains poorly understood. This dissertation investigates the physicochemical properties, tribological behavior, and tribofilm formation mechanisms of choline amino acid PILs to establish structure–property–performance relationships for sustainable lubricant design. Ten choline amino acid PILs containing glycine, alanine, lysine, leucine, isoleucine, aspartic acid, …

Mechanistic And Spatio-Temporal Modelling Of Cassava Whitefly (Bemisia Tabaci) Risk Under Climate Change: Projections For Africa With Case Evidence From Malawi, Lumbani Benedicto Banda, Frank Thomas Ndjomatchoua, Ritter A. Guimapi, Komi Mensah Agboka, Abdelmutalab G.A. Azrag, Wezi G. Mhango, Trust Kasambala Donga, Chikondi Makwiza, Karl H. Thunes, Elfatih M. Abdel-Rahman

All Peer-Reviewed Publications

The cassava whitefly (Bemisia tabaci) greatly constrains cassava production across Africa due to its role as a vector of viral diseases that cause substantial yield losses. Effective management of this insect pest requires detailed knowledge of its spatio-temporal distribution, however long-term datasets are scarce. Mechanistic models circumvent these long-term data needs by modelling temperature-dependent processes that govern population dynamics. Nevertheless, their application to B. tabaci remains poorly explored. Here, we developed a mechanistic model to derive a risk index (RI) for B. tabaci across Africa, focusing on Malawi. The model integrates the effects of temperature on the life stages of …

Environmental And Socioeconomic Effects Of Roundtable On Sustainable Palm Oil Certification: A Systematic Review And Meta-Analysis, Kibrom T. Sibhatu, Matin Qaim

All Peer-Reviewed Publications

Palm oil is the most widely produced and consumed vegetable oil worldwide, but its production is associated with deforestation and other environmental and social problems. Roundtable on Sustainable Palm Oil (RSPO) is the only internationally-recognized voluntary certification standard aimed at mitigating such problems. Many studies examine RSPO’s effects on particular outcomes in specific contexts, but a consolidated global assessment is lacking. Here, we systematically review the literature and identify 53 original studies covering RSPO effects in various countries of Asia, Africa, and Latin America. Where data availability permits, we also conduct meta-analysis. Results reveal that RSPO can lead to environmental …

System For Privacy-Preserving Cryptographic Auditing Using Zero-Knowledge Proofs, N/A

Defensive Publications Series

Systems for enterprise security may rely on high (fidelity) logging, which can involve collecting and storing large volumes of sensitive event metadata, creating security and privacy liabilities. A cryptographic auditing framework may be utilized where, instead of storing raw event data, a system can generate and store a succinct cryptographic proof, such as a zero-knowledge proof. This proof can serve as a mathematical attestation that a permitted action occurred in compliance with a governing policy, potentially without revealing the specific details of the user or the action. This approach can be used to generate a tamper-evident, privacy-preserving, and space-efficient audit …

Establishing New Territorializations In A Community-Engaged Tesol Program: Insights From College Student Experiences, Lourdes Cardozo-Gaibisso, Savanah Stewart, Daniela Coral Patino, Haylee Morman

Journal of English Learner Education

This article presents a community engaged learning experience and its instructional implications for TESOL. The instructional cultures established in policies and practices that dictate college students’ engagement with the “real world” are dependent upon the ways they respond to and translate existing territories in social, cultural, political, and linguistic interactions with multilingual learners and communities. From a Deleuzoguattarian perspective on territorialization and deterritorialization, this article problematizes how college students perceive, and question established norms and taken-for-granted ways of doing emphasizing the importance of reflective practices, ongoing supports for all participants involved, and partnerships with local communities, advocating for a nuanced …

Sustained Reading: Multilingual Learners Exploring The Language Of A Text, Priscila J.B.M. Costa, Luciana C. De Oliveira, Meghan Love

Journal of English Learner Education

In US schools, multilingual learners (MLs) are expected to meet the same rigorous disciplinary standards as their English-speaking peers while also developing proficiency in English. This article demonstrates how sustained reading, as part of the Teaching and Learning Cycle, can support MLs' access to disciplinary literacy through the explicit attention to language features. Grounded on the Language-based Approach to Content Instruction (LACI), the article presents a classroom vignette from a 5th-grade social studies lesson in which MLs dissected a mentor text. The lesson illustrates how code-breaking within sustained reading makes disciplinary language visible, helping students notice the linguistic choices common …

Matching The Stars To A Game Of Aggression, E. Chambers, Kristen Barnard

Electronic Proceedings of Undergraduate Mathematics Day

Region against region and army against army, we chart and battle among the stars! This paper studies the combinatorial game Aggression using graph-theoretic models. We focus on how winning strategies depend on the structure of the game graph, with particular attention to star graphs, matchings, and their disjoint union. The results presented here come from research conducted under the guidance of Dr. Kristen Barnard during the summer of 2025. We begin by introducing the game, describing the rule set used, and explaining how maps can be represented as graphs. From there, we examine how adjacency, placement order, and tie-breaking rules …

Strict Steiner Symmetrization For Polygons, Joseph Chai, Sun-Yung Alice Chang

Electronic Proceedings of Undergraduate Mathematics Day

In this note, we introduce a method called Strict Steiner Symmetrization (see Section 2.2) that is an altered form of Steiner Symmetrization that fixes the number of vertices. The context of this paper will be to prove the Isoperimetric Inequality in R2 via approximation by polygons. Specifically, to establish that among all n-gon domains in the plane, the regular m-gon, m ≥ n, uniquely minimizes the isoperimetric ratio and that the limit of this regular polygon (that is the circle) achieves equality in the isoperimetric inequality. This note is an extracted portion of my junior thesis (A Polygonal Proof of …

Huffman Tree Uniqueness, Elijah Diller, Adam Volk

Electronic Proceedings of Undergraduate Mathematics Day

The Huffman algorithm is a standard algorithm used to generate an optimized binary encoding of a string. Using this algorithm, it may be possible to come up with more than one possible optimized binary encoding for a given string, so the following question arises: what strings have a unique optimized binary encoding? By unique encoding, we mean a unique vertex-labeled binary tree resulting from the Huffman algorithm. We do not worry about edge labels as every binary tree corresponding to a string with n distinct characters has 2n−1 ways of assigning the edge labels and determining the code. This investigation …

Predator-Prey Dynamics: Exploration And Logistic Extension Of The Lotka-Volterra System, Amanda Maylath, Samuel Brensinger

Electronic Proceedings of Undergraduate Mathematics Day

The Lotka-Volterra system is a classic model of predator–prey interactions, capturing the interdependent growth and decline of two species. Using a dynamical systems approach, we identify fixed points, linearize the system via the Jacobian, and analyze phase space trajectories to determine stability and long-term behavior. This analysis provides insight into predator-prey dynamics without requiring explicit solutions. We further extend the model by incorporating a carrying capacity for the prey, reflecting more realistic population dynamics.

Numerical Solutions Of The Poisson And Heat Equations Via Wave Kernel-Based Particular Solutions, Braylon Smith, Anup Lamichhane

Electronic Proceedings of Undergraduate Mathematics Day

In this paper, we investigate the closed-form particular solutions of Poisson’s equation using the wave kernel as a forcing term. We explore how the method of approximate particular solutions can be applied to obtain numerical solutions of partial differential equations such as the Poisson and heat equations with Dirichlet boundary conditions in 1D. Numerical experiments carried out in MATLAB validate that the derived closed-form particular solutions provide accurate numerical results, demonstrating the effectiveness of the proposed approach.

The Recovery Of Meaning In A Digital Age: E-Discovery And The Renewal Of Judgment, William F. Hamilton

Journal of Technology Law & Policy

Modern litigation unfolds within a dense and expanding digital environment. Nearly every human activity now leaves behind emails, documents, metadata, collaborative communications, and machine-generated records that together form the factual foundation of contemporary litigation. This Article argues that electronic discovery is not merely a technical, managerial, or compliance process, but a core litigation practice concerned with the recovery, reconstruction, and rehabilitation of the factual world on which judgment depends.

Tracing the evolution of discovery from its twentieth-century roots to the present era of pervasive digital evidence, this Article shows how electronically stored information (ESI) continues to alter the dynamics of …

Exploring Early Career Public General Education K–6 Teachers’ Experiences With Their Training For Teaching Special Education Students In Inclusive Classrooms, Alexandra E. Ray

Doctor of Education Program Dissertations

Although Canada is often regarded as a leader in inclusive education, reports note that many students’ needs remain unmet and inclusion is typically implemented by placing students in mainstream classrooms with individualized accommodations. This qualitative phenomenological study explored the lived experiences of seven early career K–6 public general education teachers in Ontario (1–4 years of practice) as they engaged in inclusive education and prepared to teach students with special needs. Participants reported that teacher preparation coursework presented inclusive models only superficially, professional development was fragmented and insufficient prompting self-directed learning and structural constraints in schools limited individualized support. Teachers described …

A Century Of Safer Skies: Statistical Insights Into Aviation Accidents And Death Rates, Abhijeet Regmi

Journal of Aviation Technology and Engineering

The purpose of this study is to determine whether the recent advancements in the technology used for aircraft maintenance and repair have resulted in an increase or decrease in the accident and fatality rates of aviation incidents and accidents. The primary concerns are the extremely low survival rates in aviation accidents and the necessity to determine whether or not the accident and fatality rates are declining in light of recent technological advancements. If the rate is rising, we must prioritize passenger and crew safety more and adhere to tight regulations when performing repairs and maintenance. The data were compared for …

The Open Wiki Of Electrochemical Methods (Owem): A Community-Driven Educational Resource, Anderson Fuller, Devin Rappleye

Reviews, Analyses, and Instructional Studies in Electrochemistry (RAISE)

The traditional resources for learning electrochemical methods—textbooks, academic literature, and university coursework—remain essential but are limited in accessibility, update frequency, and practical usability. This paper introduces the Open Wiki of Electrochemical Methods (OWEM), an open-access, community-driven platform designed to complement these resources. OWEM organizes content into equations, definitions, methods, tutorials, and supplementary articles, with a heavy emphasis on experimental relevance. A case study on cyclic voltammetry demonstrates how OWEM consolidates foundational theory, lesser-known results, and practical guidance within a continuously maintainable framework to benefit the broader electrochemistry community.

Aspirational Mirrors: A Conceptual Model Of Alumni-Led Near-Peer Outreach For Precollege Engagement In Ocean Engineering, Habibi Palippui, Juswan Sade

Journal of Pre-College Engineering Education Research (J-PEER)

Precollege students in Indonesia, especially in rural and coastal regions, often lack exposure to engineering disciplines due to social, geographic, and informational barriers. This essay proposes a conceptual model of alumni-led near-peer outreach as an affective and culturally grounded mechanism to engage high school students in ocean engineering. Drawing from theories of social similarity, possible selves, and engineering identity, the model conceptualizes alumni as “aspirational mirrors” who influence students not merely through information but also through identification. The model outlines four primary mechanisms—social connection, narrative engagement, aspirational mirroring, and early identity activation—and also accounts for contextual variables such as school …

Object Redaction For High-Resolution Images Using Geometrically Aligned Generative Patches, Mira Leung

Defensive Publications Series

Redacting objects from high-resolution, wide-aspect-ratio images, such as panoramas, can be challenging, as certain automated methods may introduce resolution degradation, unpredictable cropping, or visual artifacts. Systems and methods can utilize an iterative pipeline that combines object detection with constrained generative inpainting and geometric alignment. A process may, for example, identify and mask target objects, provide a version of the image with blurred masked areas to a generative model for inpainting, and then geometrically align the generative model's output to correct for distortions. The aligned output can be used as a patch, selectively compositing the generated content into the masked regions …

The Substrate Pushback Principle: Replacing Particle Dark Matter With Holographic Confinement Fields, Christopher L. Eckes

Defensive Publications Series

This paper introduces the Substrate Pushback Principle, a theoretical framework that replaces particle-centric dark matter models with an emergent informational cosmology. Instead of introducing hypothetical ultra-light bosons, we demonstrate that galactic dark matter halos can be modeled as non-local confinement fields generated by the holographic limits of spacetime. By mapping the baryonic stress-energy tensor to an information-load metric bounded by Bekenstein limits, we show that high-density galactic cores trigger an inward, geometric stabilization pressure from the spacetime substrate. This computational surface tension inherits the exact macroscopic wave mechanics of contemporary Fuzzy Dark Matter (FDM) models. Furthermore, by defining the substrate's …

Spatially Modulated Wavefront Quantum Key Distribution With Non-Local Quantum Zeno Dynamic Phase-Collapse (Geometric Wavefront Scytale With Entanglement-Triggered Self-Immolation), Johny Manuel-Devadoss, Jayden Johnson

Defensive Publications Series

This disclosure describes a method and system for securing free-space Quantum Key Distribution (QKD) against intercept-and-resend, quantum cloning, and wide-aperture phase-matching attacks by employing multi-spatial mode quantum states combined with real-time, non-local phase collapse. Rather than encoding cryptographic keys in conventional linear single-photon streams, the system distributes information across the Orbital Angular Momentum (OAM) and radial phase profiles of a macroscopic, spatially sculpted wavefront through a dynamically varying Topological Transposition matrix, M(t). This approach renders the encoded information inherently orthogonal to conventional linear eavesdropping apertures while enabling high-dimensional quantum state encoding.

To protect against partial interception and coherent cloning attempts, …

Informational Exomemory Cosmology: Dark Energy As The Semiclassical Landauer Erasure Cost Of Horizon Microstates, Christopher L. Eckes

Defensive Publications Series

This paper presents a rigorous theoretical framework—Informational Exomemory Cosmology (IEC)—that derives Dark Energy entirely as an emergent, thermodynamic byproduct of cosmic information processing. Rather than postulating a fundamental scalar field or an intrinsic vacuum energy density (\(\rho _{\text{vac}}\)), we model the three-dimensional (3D) cosmic volume as a holographic projection governed by a global, invariant two-dimensional (2D) boundary: the Cosmological Future Causal Horizon.

Every localized physical interaction inside the bulk updates the quantum configuration state of the universe. Because the ultimate future horizon features a strict Bekenstein-Hawking memory capacity, the universe must continuously clear its cache of obsolete microstates to maintain …

Zheng Zhenduo And The Problem Of Priority In World Literature, Daniel M. Dooghan

CLCWeb: Comparative Literature and Culture

This essay investigates how Zheng Zhenduo (郑振铎 1898–1958) developed a theory of world literature in response to threats to China both politically from without and culturally from within. Centered on an analysis of his 1922 article “A View on the Unification of Literature” (Wenxue de tongyiguan 文學的統一觀), the essay argues that although Zheng believed like many of his contemporaries in the transformative effects of reading world literature in translation, that does not constitute the entirety of his theorization of world literature. Instead, he accepted the first-move advantage of other national literatures in defining both world literary standards and literature …

Detection And Diagnostic Screening Of Breast Cancer: A Systematic Review And Future Frontiers, Lama Yassine, Amira J. Zaylaa

BAU Journal - Science and Technology
