A Study Of Electron- And Photon-Induced Dissociative Electron Attachment To Molecules And Within Anion-Molecule Clusters, Mahmudul Hasan

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Dissociative electron attachment (DEA) is a resonant process in which a molecule captures a low-energy electron, forming a transient negative ion (TNI). Subsequently, this unstable TNI fragments into a stable anion and one or more neutral fragments. DEA is crucial in various phenomena, ranging from atmospheric and radiation chemistry to processes occurring in plasmas, and is particularly significant in the context of radiation-induced damage to biological molecules. This study uses different experimental methods to better understand the fragmentation in molecular anions forming through dissociative photoexcitation and electron attachment. We have developed an experimental apparatus for dissociative photoexcitation studies. This apparatus …

Understanding The Effect Of Environment- And Organization-Specific Factors On Sustained Crowdsourcing Contest Participation, Hanieh Javadi Khasraghi, Xuan Wang, Yaojie Li, Yi Liu

Management and Marketing Faculty Publications

Crowdsourcing contests have increasingly become a recognized sourcing mechanism for problem-solving and decision-making in organizations. The continued participation in crowdsourcing contests undoubtedly determines the success of the crowdsourcing platform. While previous studies have investigated a myriad of factors influencing individuals’ sustained participation in crowdsourcing contests, environment- and organization-specific factors have yet received little attention from researchers. The purpose of this paper is to fill this research gap by investigating how team ties, organization exposure, and experience with the organization can affect sustained participation in crowdsourcing contests.

Price Exuberance And Contagion Across Housing Markets: Evidence From Us Metropolitan Areas, Md Shahedur R. Chowdhury, Damian S. Damianov, Diego Escobari

School of Economics and Finance Faculty Publications

Contagion occurs when cross-market correlation increases because of a shock to one market. Identifying shocks as episodes of house price exuberance, we provide evidence for contagion effects among the largest metropolitan markets in the US. We find that changes in income, interest rates, and unemployment also create contagion effects. These empirical findings are consistent with a model in which shocks to house prices and economic variables relaxes households down payment constraints and increases household mobility and housing demand. These effects are established in an equilibrium framework in which house prices and household choices are determined endogenously, and we account for …

The Philosophy Of Incarceration And Punishment And Its Evolvement. Is It Enough?, Katherine Sebok

Capstone Projects – Politics and Government

This research project explores the evolution of incarceration philosophies and their disconnect from outdated prison infrastructure in the United States, with a focus on Illinois. From ancient civilizations’ reliance on retributive justice to the modern era’s emphasis on rehabilitation, punishment practices have evolved, yet many facilities remain stuck in the past. The “tough-on-crime” era deepened the divide, leading to overcrowding and neglect. While recent reforms prioritize rehabilitation, progress is hindered by outdated facilities. Illinois’ plans to demolish and rebuild Logan and Stateville Correctional Centers offer renewed hope, but the lengthy process requires significant investment and commitment from all involved parties.

The Role Of Nr4a Transcription Factors In The Body And Their Effects In The Pancreatic Beta Cell, Jacob A. Herring

Theses and Dissertations

A central aspect of type 1 and type 2 diabetes is decreased functional β-cell mass which leads to systemic glucose dysregulation. Functional β-cell mass takes into account β-cell insulin secretion, β-cell proliferation, and β-cell survival. Several treatments are currently used to help maintain glucose levels in individuals with diabetes. However, cures for these diseases are not available due to inability to expand functional β-cell mass. Transcription factors control expression of target genes critical for various functions, and transcription factors that control β-cell function, proliferation and survival play a significant role in β-cell development and function. A more thorough examination of …

Influence Of Language Evolution And Compiler Advances On Program Creation: Implications To Electronics Engineering Education, Ralph Anthony Ramos Rafael, King Harold A. Recto

Electronics, Computer, and Communications Engineering Faculty Publications

The progression of programming languages, from machine and assembly languages to high-level and very high-level languages, and now towards natural language processing and artificial intelligence, has significantly influenced program creation and assembly. Each generation has brought notable advancements in abstraction, readability, and usability, making programming increasingly accessible and efficient. Early languages such as machine and assembly languages were hardware-dependent and low-level, concentrating on direct interaction with hardware. This paradigm shifted significantly with the emergence of high-level languages, which abstracted hardware specifics and emphasized logic and functionality. These shifts have had profound impacts, particularly in Engineering Education, by potentially reducing the …

The Large-Scale Environments Of Active Galactic Nuclei, Grayson C. Petter

Dartmouth College Ph.D Dissertations

It is now recognized that the energy released by accreting supermassive black holes observed as Active Galactic Nuclei (AGN) is integral in shaping the dynamics of baryons on up to cosmological scales, and AGN thus play a significant role in regulating the formation and evolution of galaxies. Studying the clustering properties of AGN reveals which environments they release this feedback energy into, testing models of AGN-galaxy coevolution and AGN structure. In this thesis, I leverage wide-area photometric and spectroscopic survey data to measure the clustering properties of various AGN samples containing millions of systems, placing tight constraints on the properties …

Geometrically Exact Beam Theory For Gradient-Based Optimization, Taylor Mcdonnell, Andrew Ning

Faculty Publications

Decades of research have progressed geometrically exact beam theory to the point where it is now an invaluable resource for analyzing and modeling highly flexible slender structures. Large-scale optimization using geometrically exact beam theory remains nontrivial, however, due to the inability of gradient-free optimizers to handle large numbers of design variables in a computationally efficient manner and the difficulties associated with obtaining smooth, accurate, and efficiently calculated design sensitivities for gradient-based optimization. To overcome these challenges, this paper presents a finite-element implementation of geometrically exact beam theory which has been developed specifically for gradient-based optimization. A key feature of this …

Solving Unsteady Potential Flow Problems In O(N) Time, Ryan Anderson, Andrew Ning

Faculty Publications

Design of vertical takeoff and landing aircraft is challenging in part due to significant aerodynamic interactions between rotors and wings. Computational models can aid in their design, but are computationally expensive. 3-D panel methods coupled with vortex particle wakes offer an attractive solution, but solving for the panel strengths scales poorly for large problems. Multigrid methods, such as Krylov subspace methods in conjunction with the fast multipole method (FMM), have been demonstrated to reduce the scaling to O(𝑁). We explore the performance and limitations of the Krylov-FMM method, traditional matrix-powered GMRES, LU decomposition, and a novel O(𝑁) multigrid approach to …

Persevering Through Communication Challenges: A Qualitative Descriptive Exploration Of Communication Experiences In Aphasia, Tyson G. Harmon, Camille Williams, Garrett Cardon, William S. Evans

Faculty Publications

Background

People with aphasia often experience activity limitations and participation restrictions despite wanting to engage in communication activities that are satisfying and meaningful. Communication partner support, the complexity of the communication environment, and the thoughts and feelings of people with aphasia have important implications for both language processing and communicative participation. The perspectives of PWA about the role that environmental and personal factors (e.g. thoughts and feelings) play in their communication experiences could inform clinical practice.

Aims

To qualitatively explore the communication experiences of people with aphasia and how environmental demands and personal factors (especially emotional responses) affect these experiences. …
