The Digital Neuron: Neural Cellular Automata For Neural–Symbolic Translation, Nicole Assenza

SMU Data Science Review

A neural cellular automata (NCA) architecture, referred to as Pluto’s NCA, was developed to characterize bilateral communication and semantic reciprocity between symbolic representations and a spatially distributed update field. The architecture employs an encoder–automata–decoder pipeline that maps symbolic inputs into a multichannel state field and reconstructs them through agreement-driven attractor convergence within a stable semantic attractor landscape. System behavior was evaluated under controlled perturbations, including rhythmic desynchronization, graded ablations, correlated and independent noise, and percolation-based structural degradation. Quantities such as Agreement(t), internal coherence Aᵢ(t), the recovery time constant τ, and the critical percolation threshold pc were measured to assess stability, …

Organic Synthesis Of A Hydrazine Functionalized Ammonium Compound For Improved Capture Of Aldehyde Metabolites From Exhaled Breath, Po'iu N. Burgo

Undergraduate Theses

Breath analysis has emerged as a non-invasive and inexpensive way to screen for respiratory diseases. This technique involves measuring concentrations of specific metabolites found in exhaled breath that serve as a biomarkers for disease. A subclass of volatile organic compounds called α,β-Unsaturated aldehydes, products of the lipid peroxidation mechanism, are underrepresented as biomarkers of lung cancer. These have been found to have relatively increased concentrations in the exhaled breath of lung cancer patients compared to a healthy patient. One of the reasons that these metabolites have been underreported is that the techniques used to measure and characterized exhaled metabolites do …

Assessing Passenger Electric Vehicle Growth Strategies And Their Impacts On Electricity Demand Load And Co2 Emissions In Aceh Province To Achieve Net Zero Emission Target By 2060, Taufik Hidayat, Widodo Wahyu Purwanto

Journal of Materials Exploration and Findings

The electrification of the transport sector is a crucial pathway for achieving Indonesia’s Net Zero Emissions (NZE) target by 2060. This study assesses the potential impact of passenger electric vehicle (EV) penetration on electricity demand and CO2 emissions in Aceh Province through a scenario-based modelling approach. Two policy-aligned scenarios are assessed: a low-penetration (LP) scenario and a high-penetration (HP) scenario. Using the Gompertz model and the ASIF framework, total CO2 emissions were projected from 2020 to 2060. Results show that although higher EV penetration reduces direct emissions from internal combustion engine (ICE) vehicles, total CO2 emissions increase more significantly under …

Dynamics And Energetics Of Fast Waves From The Earth's Surface To The Lower Thermosphere, Richard L. Walterscheid, Michael P. Hickey Ph.D.

Publications

We use a Full Wave Model to examine the dynamics and energetics of waves that can be excited in the troposphere by a large explosive event. We find resonant structures in phase speed wavenumber space that can have substructures with distinct properties. The primary waves found are Lamb waves and fast deep waves (denoted 𝐿′) that have a hybrid internal-external wave nature and were recently identified in observations. Lamb waves and thermospherically ducted waves are branches of two continuous forms separated by a gap in which Lamb waves are preempted by Lamb speed waves oscillating with the buoyancy frequency. We …

On Humans And Ai: A Financial Reporting Dilemma, Jeremy Bertomeu, Edwige Cheynel, Radhika Lunawat, Mario Milone

Olin Business School Faculty Research

This study examines the resolution of ethical dilemmas in financial reporting by human participants and large language models. Participants act in the role of a CFO deciding whether to discontinue a prior policy with biased reporting; however, the bias is known and corrected by investors whereas a change may temporarily mislead investors. We find that models are less amenable to competing ethical considerations than humans, and exhibit greater preference for truthful reporting. Moreover, they respond with greater consistency to institutional ethical guidance, while humans become more indecisive under pressure from management. The models exhibit more internal coherence between their moral …

Exploring The Design Of A “Salon-Like” Mathematical Experience In A High School Setting, Grace Simser

University of Montana Conference on Undergraduate Research (UMCUR)

Current practices for teaching math in school are student-centered, but highly orchestrated by teachers. While these models of education are widely accepted, math classrooms do not often afford students the space for rich conceptual play and low-stake interaction with the material. To support these goals, researchers have proposed “salon-like” mathematical spaces, where there are no roles like “teacher” and “student”, and nobody knows the answer to the question being posed. In this study, we are examining how to foster salon-like spaces within traditional schools.

My study took place in a cafeteria of a local high school, during lunch. I was …

Expanding University Of Montana's Contract Management System, Brooke Odenthal

University of Montana Conference on Undergraduate Research (UMCUR)

The University of Montana is currently losing millions of dollars due to their lack of efficiency and oversight on contracts. There are many contracts that affiliates of the university have signed without authorized oversight. Without the correct oversight, the university ends up signing multiple contracts for the same product. This also leads to members of the university wrongly giving away valuable data and information to companies without properly signing contracts. All of their contracts are scattered across campus, some signed correctly and some not. These documents are stored in various offices, departments, and using a mix of storage systems. This …

Evaluating Motivation In Stem Education: A Positive Self-Talk Intervention, Tiffany Copeland, Richard Allen, Sophia Pham, Kristin Gagnier

INTRODUCTION: This study evaluated a social-emotional learning intervention that taught positive self-talk to high school students from underrepresented minority groups in science, technology, engineering, and math (STEM). The setting of this study was a place-based program that immersed students in hands-on STEM activities while located in Philadelphia’s life science hub. Before taking a science assessment, students set effort-based goals and learned to say self-talk statements such as “I will give my best effort” and “Even when it's hard, I will give 100%.”

METHODS: This mixed-methods program evaluation compared pre- and post-intervention data using a paired-samples t-test, linear regression, and correlation …

Inferring Properties Of Binary Black Hole Mergers From The Ringdown, Serena R. Fink

University of Montana Conference on Undergraduate Research (UMCUR)

The effect of progenitor masses and spins on the inspiral phase of a gravitational wave signal from a binary black hole merger is relatively well understood for the case where spins are aligned with the orbital angular momentum. Less is known about how progenitor properties -- especially misaligned spins -- impact the ringdown. The accuracy and precision with which inspiral parameters (component masses and spins) can be inferred from the ringdown alone remains an open question. As several high-mass (most ringdown-dominated) systems observed by the Laser Interferometer Gravitational-wave Observatory (LIGO) have misaligned spins, the ability to predict inspiral properties from …

To achieve this, Slurm assigns each job a priority score, which is influenced by several factors, including a “Fairshare” score. Fairshare is designed to balance resource usage over time by prioritizing users or groups who have consumed fewer computational resources relative to their allocated share. There are two algorithms that make up Fairshare, there is the classic algorithm that was previously …

Graph Colorings Up To Symmetries, Stone Cj Cook

University of Montana Conference on Undergraduate Research (UMCUR)

The infamous four-color problem (4CP) dates back to 1852 and asks whether four colors suffice to color a map so that countries sharing a border receive distinct colors. This year marks the 50th anniversary of the problem's resolution. The 4CP inspired a bountiful collection of mathematics in the subject now known as "graph theory." A graph models any sort of network such as the Internet, transportation systems, and the neural networks that underpin modern AI. Graphs consist of two components: "vertices" and "edges." We visualize the vertices as dots on a page and the edges as lines connecting pairs of …

Computing The Tree Packing Conjecture, Nathaniel T. Adams

University of Montana Conference on Undergraduate Research (UMCUR)

The Gyárfás tree packing conjecture [1] states that any collection of trees (T1, T2, . . . , Ti) on 1, 2, . . . n vertices can be edge-disjointly packed into a complete graph on n vertices. Alternatively, this conjecture states that such a family of trees can be “glued” together to produce a complete graph on n vertices. Although many partial results are known (See Cisiński and Zak [2], Janzer and Montgomery [3], Balogh and Palmer [4]), ˙ the conjecture has remained open since 1970. This conjecture is computationally challenging, naively requiring superexponential number of computations. This paper …
