All Wrapped Up: How Choice Of Egg Wrapping Substrate During Oviposition Site Selection Affects Predation And Embryonic Growth In Eastern Newts, Anna Prohofsky

Master’s Theses

Parental care behaviors have a significant impact on the survivorship of offspring and therefore the inclusive fitness of the parent. These behaviors are broad and varied and include defending against predators, acquiring food, and choosing where to lay their eggs. The latter, oviposition site selection, has significant impact on embryo survivorship in oviparous animals, as the chosen sight can impact factors such as incubation temperature, predation risk, and resource availability. For amphibians, oviposition site selection is particularly crucial as their eggs lack a calcareous shell, leaving them more susceptible to environmental conditions and predation. In response to this, amphibians have …

The Geometry Of Planetary Systems, Emma Marie Cain Louden

Yale Graduate School of Arts and Sciences Dissertations

The study of exoplanetary systems offers an observable window into the processes governing celestial bodies' formation, evolution, and current structure. Central to understanding these systems is their geometry, which encompasses the orientations, alignments, and spatial relationships among planets and their host stars. This dissertation investigates the pivotal role of planetary system geometry—particularly obliquities and orbital resonances—in illuminating the formation pathways and long-term evolutionary trends of both solar and exoplanetary systems.

This dissertation explores these themes through three comprehensive studies. Chapter 2 focuses on the role of tidal dissipation in shaping short-period exoplanets, examining whether the presence of obliquity-driven tidal interactions …

Controlling And Protecting Quantum Information In Superconducting Oscillators, Aniket Maiti

Yale Graduate School of Arts and Sciences Dissertations

Modern quantum experiments allow the precise manipulation and measurement of many-body quantum states, pushing quantum mechanics from a testable theory to a utilizable technology. The central promise of these experiments is to process quantum information for exponential advantages in computing, sensing, and communication. An interesting way to achieve such a processor is to manipulate quantum information stored in the continuous-variable (bosonic) phase space of electromagnetic radiation. Since photons in free space do not interact, such an approach necessarily requires the introduction of nonlinearity through strong light-matter couplings. However, since all matter is lossy, this inevitably introduces a trade-off between the …

Understanding Violence In Juvenile Correctional Facilities: A National Study Of Victim-Offender Overlap In The United States, Tzu-Ying Lo, Yu-Hsuan Liu, Amy Adamczyk

Publications and Research

The phenomenon of victim-offender overlap within juvenile correctional facilities is an underexplored area in criminological research. This study examines the prevalence and correlates of victim-offender overlap using data from two collections of the National Survey of Youth in Custody conducted in 2008–2009 and 2012. Our findings reveal that the victim-offender overlap group constitutes a significant proportion of incarcerated youth. Multinomial logistic regression analysis indicates that institutional factors, such as correctional officer legitimacy, in-facility gang membership, fear of inmate assault, experience of filing complaints against staff, and time served, significantly differentiate victim-offenders from the three other groups: victims-only, offenders-only, and those …

Victim-Offender Overlap Among Incarcerated Youth In The United States: A Bivariate Probit Analysis Using National Data, Tzu-Ying Lo, Yu-Hsuan Liu, Amy Adamczyk

Publications and Research

For many crimes, people who are the perpetrators may also be the victims. While several studies have investigated the victim-offender overlap, very few have examined the relationship for incarcerated youth where institutional conditions can exacerbate the overlap. Drawing on ideas from routine activities theory, this study explores the victim-offender overlap among incarcerated American youth using data from the 2008–2009 National Survey of Youth in Custody (NSYC-1, N = 8,625) and the 2012 National Survey of Youth in Custody (NSYC-2, N = 8,125). Findings from a bivariate probit regression indicate that younger age, higher facility populations, negative perceptions of officer legitimacy, …

Actual measurements of the substrate depth beneath the sediment and ground-penetrating radar (GPR) scans of the beach reveal that the coral reef bedrock in KT slopes landward. A field survey of the seagrass area in KT was conducted, and three cross-sectional profiles were analyzed to determine their topography, yielding a median sediment thickness of 88.2cm. Based on these measurements, the sediment volume was …

Calculation Of Aquifer Transmissivity From Borehole Resistance Measurements And Pumping Test Results, Fen-Rong Yang, Chien-Wei Huang, Tien-Kuen Huang

Journal of Marine Science and Technology–Taiwan

Transmissivity is a crucial hydrogeological parameter for evaluating groundwater resources. This parameter is conventionally evaluated using pumping tests; however, these tests are costly and can be conducted at few sites. Many researchers have used ground resistance and pumping test data to estimate various hydrogeological parameters. In this study, borehole resistance survey and pumping test data collected by the Taiwan Groundwater Monitoring Network were used to establish the relationship between transmissivity and formation factor for aquifers in the Zhuoshui River alluvial fan. This relationship was then used to estimate the water output of the aforementioned aquifers in a cost-effective manner from …

A Neural Network-Based Sliding Mode Adaptive Control System For Unmanned Surface Vehicles, Sun Qiaomei, An Liang, Jiang Linglin

Journal of Marine Science and Technology–Taiwan

Over the past decades, numerous studies have explored the use of autonomous unmanned surface vehicles (USVs). Successful USV operation requires a robust tracking control system to perform a range of tasks. However, USV dynamics are uncertain, time-varying, and nonlinear. This paper presents a neural network-based sliding mode adaptive control (NNSMAC) system to enhance USV tracking performance. Trajectories were generated using spline and polynomial interpolation based on a set of N predefined waypoints. Simulation results show that the proposed method outperforms traditional sliding mode control in error reduction, enabling more effective tracking.

Scaling Laws For Diffusion In Crystallized Plasma From Molecular Dynamics, Dany Yaacoub

Theses and Dissertations

Diffusion coefficients for crystallized Coulomb plasmas are essential microphysics input for modeling white dwarf cores and neutron star crusts. Solving for diffusion coefficients require running large molecular dynamics simulations with thousands of particles over millions of timesteps. The diffusion in a crystallized plasma has been largely ignored and is often taken to be zero in stellar evolution codes. We find that not only is this incorrect, but we find that the diffusion in a crystallized plasma can be modeled completely using a universal scaling law independent of screening. Our simulations also show that the dominant mode of diffusion in a …

Nutrient Transport And Transformation In Anaerobic Co-Digestion Of Crop Residues And Swine Manure, Shelby Stoner

Theses and Dissertations

Cover crops may improve soil quality, water quality, soil health, reduce soil fertilizer use, and increase nutrient availability to cash crops. The benefits of cover crops are discussed due to the below ground presence of cover crops, but the aboveground biomass can serve as a source of sustainable energy through anerobic digestion. The nutrients in the above ground biomass can also be recycled and reused through land application of digestion effluent. We have tested anaerobic co-digestion of different biomass feedstocks: cover crops, soybean stalk, and corn stover with swine manure using both small and pilot scale digesters. Nutrients, specifically NPK, …

How I Came To Understand What Art Was, Ilse Miller

Theses and Dissertations

This thesis explores my multidisciplinary art practice through three specific types of work: mobiles, books, and boxes. Each type of artwork functions as a vessel used to preserve objects and fleeting moments. Rooted in Anna Kornbluth's "aesthetic regime of immediacy," the work balances preservation with loss and intuition with craft. Inspired by Rauschenberg and Abercrombie, it challenges artistic boundaries by using immediate, everyday materials. These mobiles, books, and boxes become conduits for memory and invite viewers to connect personal and collective experiences.

More Than Players, More Than Coaches: Institutional Agents And Youth Development In Urban And Suburban Minority-Majority Neighborhoods, Rainah N. Folk

Theses and Dissertations

Institutional agents play a crucial role in shaping youth development. While the institutional agent framework is well established in postsecondary research, less is known about its role during mid-adolescence. Using relational ethnography and responsive interviewing, this study compares an urban and a suburban high school in minority-majority neighborhoods in Cook County, Illinois, to explore how development is influenced through relationships between sport coaches and high school athletes. Athletes in both contexts face significant challenges tied to neighborhood conditions and socioeconomic status. In response, coaches form deeply caring and supportive relationships, though their roles diverge in ways shaped by their urban …

The Elemental Analysis Of Groundstone Celts From Noble-Wieting Using The Pxrf: A Provenance Study, Julian A. Marvel

Theses and Dissertations

Groundstone axes, or celts, were prehistoric stone tools used for chopping, cutting, or woodworking. Made from hard stone like basalt or granite, it was shaped by grinding and polishing rather than flaking, giving it a smooth, durable surface. Celts typically have a tapered edge and were often hafted onto wooden handles or used by hand. They were common in Neolithic cultures around the world and served both practical and sometimes ceremonial purposes. In this thesis, I analyze celts from Noble-Wieting (11ML24), a 14th-century Langford tradition village in McLean County, Illinois.

Specifically, my research addresses the following questions about these groundstone …
