An Ion-Neutral Reaction To Form Cyanobenzene And Ethynylbenzene In Titan’S Atmosphere, Rachel M. Huchmala, Vincent J. Esposito

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The ion-neutral reaction between cyanoacetylene (HC₃N) and phenyl anion (C₆H₅^–) leads to the formation of cyanobenzene (C₆H₅CN) and the ethynyl anion (C₂H^–) via a submerged, exothermic pathway. Through a different mechanism, the same two reactants also form ethynylbenzene (C₆H₅C₂H) and CN^–. These new reactions can be a foundation for the production of substituted benzenes using molecules currently present on Saturn’s largest moon, Titan. Cyclic aromatic molecules like C₆H₅CN and C₆H_{5 …}

A Systematic Approach For Controlling Tem Sample Thicknesses, Monte Kozell

Physics Faculty Publications and Presentations

Historically, TEM prep has been an artisan craft without a systematic workflow that ensures quantified control over TEM sample thickness. Over- and under-thinning is a significant problem in the TEM prep process. A direct measurement process was demonstrated to control the final thickness of the TEM lamella. Final lamella thickness was controlled by directly measuring lamella thickness in real time using a 10–15 kV SEM while performing secondary electron imaging at the mill position, allowing for (human-mediated) closed-loop processing. We demonstrated the utility of this technique by systematically thinning five TEM samples to discretely target thicknesses ranging from 100 nm …

Unlike previous quantum approaches based on Kronecker Reed–Muller (KRO) or fixed-polarity Reed–Muller (FPRM) representations, our work introduces the first Grover-based optimization framework for PKRO …

Fault-Tolerant Concurrent Data Retrieval And Processing Engine Using Acyclic Dependency Graphs, Davide Cazzin, Valentin Mercier

Defensive Publications Series

A lightweight, embedded computational graph engine provides fault-tolerant, concurrent data retrieval and processing across heterogeneous data backends. Operational tasks and data pipelines are modeled as execution nodes organized within a Directed Acyclic Graph (DAG). Programmatically defined task dependencies are dynamically resolved using topological sorting, allowing independent nodes to execute concurrently via a thread pool executor. Data payloads, represented as state mappings, are transferred between completing nodes and downstream dependent nodes to facilitate automated aggregation, joining, and transformation. Granular fault tolerance is achieved by classifying execution nodes as either critical or non-critical. When a non-critical node fails, the failure is caught, …

Knowledge-Enhanced Feature Store For Operational Ml And Llm Workflows, Saurabh Suman

Master's Theses

Modern machine learning (ML) organizations rely on feature stores to manage training and production data, yet as catalogs grow to thousands of features, semantic management becomes the bottleneck: discovery, governance, and metric selection remain largely manual. This thesis proposes and evaluates a knowledge-enhanced feature store that augments a dual-plane store with a hybrid knowledge layer—relational provenance, a lineage graph, semantic vector retrieval, and an online cache—and an LLM-driven multi-agent layer for profiling, matching, grounded metric recommendation, and pipeline generation. A working prototype was evaluated across three task families—semantic profiling, feature-matching retrieval, and discovery—using classification, ranking, and operational metrics computed by …

Temporal Variation In Picophytoplankton Pigment Phenotypes Of Two Urban Rivers, Kylee M. Lamberson, Camille E. Wendlandt, Kristin E. Forgrave, Anne W. Thompson

International Journal of Undergraduate Research and Creative Activities

Picophytoplankton are a group of photosynthetic, unicellular organisms, making them key primary producers in aquatic ecosystems. These cells numerically dominate in oceans and lakes where picophytoplankton communities contain phenotypic subpopulations that correspond to biogeographic patterns. In rivers, however, such community dynamics are less studied. We examined the phenotypic subpopulations of picophytoplankton in two converging urban river environments of Portland, Oregon (USA): the Columbia and the Willamette Rivers. From September 2022 through July 2023, we took roughly bi-weekly surface water samples and used multi-laser flow cytometry to distinguish between photosynthetic cells based on their size and pigment fluorescence. We discovered seven …

Shrinkage Of Jupiter's Great Red Spot, Richard W. Schmude Jr.

Georgia Journal of Science

This report summarizes changes in Jupiter's Great Red Spot (GRS) on the multi-decade time scale.  The mean shrinkage rates for 1960-2016 are 0.21 degrees/year (east-west) and 0.52 degrees/year (north-south).  The east-west shrinkage rate is much higher than the corresponding value for Oval BA.  Between 1878 and 2026, the GRS area shrunk by over a factor of four with a mean annual shrinkage rate of 1.0 %.  The GRS quotient (east-west length in degrees longitude divided by north-south length in degrees latitude) has decreased.  This is consistent with the GRS becoming more circular with time.  This is different than Oval BA, …

A Cognitive Accessibility Framework For Mitigating Resumption Lag Using Transitional Context Lobbies, Rachit Mathur, Payal Shah

Defensive Publications Series

This disclosure presents a cognitive accessibility framework designed to mitigate "resumption lag" and severe cognitive friction during task resumption in modern software ecosystems. While existing operating systems and web browsers facilitate context-switching away from tasks, they universally lack a mechanism to re-onboard users when they switch back, forcing users to manually reconstruct their working memory. To address this accessibility barrier, we introduce Transitional Context Lobbies—an additional strategic UI layer that re-orients users returning to suspended workspaces. The primary inventive step is a client-side engine utilizing Teleological Intent Parsing to translate a user's past behaviors, interactions, and browsing data into a …
