Interpreting Neural Operators: How Nonlinear Waves Propagate In Non-Reciprocal Solids, Jonathan Colen, Alexis Poncet, Denis Bartolo, Vincenzo Vitelli

Data Science Faculty Publications

We present a data-driven pipeline for model building that combines interpretable machine learning, hydrodynamic theories, and microscopic models. The goal is to uncover the underlying processes governing nonlinear dynamics experiments. We exemplify our method with data from microfluidic experiments where crystals of streaming droplets support the propagation of nonlinear waves absent in passive crystals. By combining physics-inspired neural networks, known as neural operators, with symbolic regression tools, we generate the solution, as well as the mathematical form, of a nonlinear dynamical system that accurately models the experimental data. Finally, we interpret this continuum model from fundamental physics principles. Informed by …

What A Waste: Nitrogen Runoff And Rates In The Maumee River (Ohio, Usa), Ryanne Antonette Cimatu

Browse all Theses and Dissertations

Excess anthropogenic nitrogen (N), primarily from agricultural field fertilization, causes nutrient runoff that stimulates harmful algal blooms (HABs) in western Lake Erie. As a critical tributary to Lake Erie, nutrient loading from the Maumee River drives the intensity of the annual summer HABs in the western basin. Knowledge gaps around rates of N transformations in the Maumee River currently hinder the calibration of in-river parameters in Soil and Water Assessment Tool (SWAT) models for the Maumee watershed. To address these gaps, this research quantified rates of ammonium uptake, ammonium remineralization, nitrification, and bacterial respiration alongside physicochemical parameters of the river. …

Spatial Distribution And Significance Of Burdens To Environmental Justice In Parramore, Florida: An Urban Resilience Perspective, Lex Tracton

Honors Undergraduate Theses

In response to climate change, economic instability, and rapid urbanization, the notion of urban resilience has gained prominence in city planning and governance. Urban resilience is the ability of a system to adapt to new baseline conditions developing as a result of disturbances. This study is focused on one of urban resilience’s sub-tenets, ecological resilience. Ecological resilience is the ability of a system to sustain ecosystem services following a disturbance (i.e. droughts, flooding, heat waves). The health of the environment prior to a disturbance informs post-disturbance ecological resilience. An already stressed and unbalanced system, or an ecosystem with degraded health, …

Over the last decades, theoretical perspectives in the interdisciplinary field of the affective sciences have proliferated rather than converged due to differing assumptions about what human affective phenomena are and how they work. These metaphysical and mechanistic assumptions, shaped by academic context and values, have dictated affective constructs and operationalizations. However, an assumption about the purpose of affective phenomena can guide us to a common set of metaphysical and mechanistic assumptions. In this capstone paper, we home in on a nested teleological principle for human affective phenomena in order to synthesize metaphysical and mechanistic assumptions. Under this framework, human affective …

How Can Educators Motivate Young People To Participate In Civic Life?, Brett L.M. Levy

Educational Theory and Practice Faculty Scholarship

Introduction:

In a democratic society, why do some people engage in civic and political action while others sit on the sidelines? What — if anything — can educators do to support informed civic participation among a wider segment of the population, even at a time of political cynicism?

These are challenging and vital issues, as we see during each election cycle and the periods in between, and I’ve tried to address them from various angles.

As a middle school social studies teacher in the early 2000s, I aimed to motivate young people to be civically engaged — sometimes succeeding, sometimes …
