An Effective Image Despeckling And Reconstruction Approach Using U-Net Based Model And Comparative Analysis, M. S. Gokmen, Bilgehan Arslan, C. Bumgardner, Abdullah-Al-Zubaer Imran

Computer Science Faculty Publications

U-Net-based deep learning models have garnered significant attention in recent years due to their strong denoising capabilities in image restoration tasks. This study critically evaluates both the strengths and limitations of these models, with a particular focus on their architectural design and constituent components, in an effort to further advance denoising performance. Based on the insights derived from these analyses, a novel architecture–termed U-Tunnel-Net–is proposed. The model is trained on the UNS and Waterloo datasets, each augmented with Rayleigh-distributed speckle noise at four distinct intensity levels (σ = 0.10, 0.25, 0.50, and 0.75), and evaluated on the UNS, BSD68, and …

“A Safe Place”: Exploring Black Couples’ Perceptions Of Black Love And Relationship Coping In The Context Of Their Lived Experiences With Racism, Melinda Murdock

Theses and Dissertations--Family Sciences

Historically, Black couples have not been studied within the context of their lived experiences as it relates to the effects of racism on relationship health. Only in the last decade have relationship scholars begun to consistently link racism-related stressors to relationship processes and outcomes. Despite the growing literature, recent studies are primarily quantitative in method and rely on samples, theoretical models, and measures that predominantly represent White couples’ experiences. It remains unclear how Black couples’ perceptions of love and relationship coping lead to resilient outcomes despite the negative effects of racism.

Therefore, the goal of the present study is to …

Rural Hospital Closure And Medicaid Expansion, Jason White

Theses, Dissertations and Capstones

Introduction: In the United States, hospitals in rural areas have been under financial pressure and have been closing at an increasing rate.  This reduces access to care for rural citizens.  The Affordable Care Act of 2010 was passed in order to increase access to medical care, partially through an optional expansion of Medicaid coverage to a larger percentage of the population.  As some states adopted the expansion and some states did not, an opportunity was created to examine the policy’s effect on rural hospital stability.

Purpose of the Study:  This study was designed to examine the effect of …

Influences Of Sex, Alcohol, And Stress On Conditioned Fear Responses, Heyam K. Mayberry

MUSC Theses and Dissertations

Learned fear responses are acquired through the identification and association of threatening stimuli with aversive outcomes. Fear responding and the proper maintenance of defensive behaviors is integral to survival. However, without the homeostasis of such systems, fear responses can become maladaptive and lead to dysregulated behavioral responding. Psychological conditions such as alcohol use disorder (AUD) and post-traumatic stress disorder (PTSD) often lead to impairments in fear learning, deficits in fear memory, and heightened fear responses. While there are clear sex differences in the prevalence of both AUD and PTSD, development of either disorder increases the risk for comorbid AUD/PTSD, leading …

Long Covid And Vulnerability To Climate Change’S Health Effects: An Informational Booklet For Healthcare Settings, Rachel Nussbaum

Public Health Theses

According to the World Health Organization, around 10–20% of people infected by COVID-19 may go on to develop symptoms that can be diagnosed as Long COVID, also known as the post-acute sequelae of COVID-19 (PASC). While the risk of Long Covid among people who received the primary vaccine series fell to 3.5% in one study, as of September 2024, over 1.3 million Americans were being infected with SARS-CoV-2 every day, and reinfections increase the likelihood of experiencing Long Covid in some studies. Continued transmission of SARS-CoV-2 has led to roughly 400 million people experiencing infection-associated chronic conditions, creating an accumulating …

Effect Of Wildfire Smoke Pm2.5 On Preterm Birth Outcomes: A Generalized Synthetic Control Analysis Of Preterm Births In The Contiguous United States From 2006 To 2020, Alexandra Maria Nechaev

Public Health Theses

Wildfire activity has intensified across the United States due to climate change, contributing to rising levels of smoke-attributable fine particulate matter (PM2.5) in ambient air. Wildfire-specific PM2.5 is linked to adverse health outcomes, including increased risk of preterm birth, a leading cause of infant morbidity and mortality. Despite growing concern, few studies have applied quasi-experimental methods to evaluate the causal effects of wildfire-attributable PM2.5 on preterm birth across large, diverse populations and geographical areas. This study estimated the effect of wildfire-specific PM2.5 exposure on preterm birth rates across all counties in the contiguous United States from 2006 to 2020 using …

Youth Views On Health Content, Ads, And Messages On Social Media, Christina Tong

Public Health Theses

This study aims to investigate youth perspectives on nutrition and healthism-related content, promotions, and messaging on social media. With the growing usage and impact of social media, especially in younger generations, it is important to recognize how social media may influence types of exposures and messaging of nutrition, weight management, and supplement-related content that youth are exposed to, which can, in turn, influence their perceptions on health and healthy lifestyles. These perspectives can then initiate engagement in helpful or harmful health behaviors. Through a qualitative analysis of focus group and interview responses of 29 Massachusetts teenagers, emerging themes were about: …

INTRODUCTION

Evidence points to dysregulated Ca²⁺ in neurons and astrocytes in models of amyloidosis. While most of these data were obtained in vitro or in vivo under anesthesia, less work has investigated these variables in awake ambulating mice.

METHODS

Astrocytic Ca²⁺ fluctuations (GCaMP8f) were imaged concomitantly with vasoreactivity in S1 on a two-photon microscope during rest and ambulation. Single-cell resolution variables were extracted using continuous wavelet transform and traditional ΔF/F measures.

RESULTS

Along with increases in amyloid beta (Aβ) accumulation, we found significant reductions in measures of astrocyte functional connectivity, pairwise correlations, and network synchronicity in older 5×FAD …

The Influence Of Glacial Topography On Fluvial Efficiency In The Teton Range, Wyoming (Usa), Sarah E. Johnson, Meredith Swallom, J. Ryan Thigpen, Michael M. Mcglue, Jason M. Dortch, Sean Gallen, Edward W. Woolery, Kevin M. Yeager

Earth and Environmental Sciences Faculty Publications

This study examines the role of topography as a dynamic boundary condition that limits the efficiency of fluvial erosion in the post-glacial Teton Range landscape. The volume of sediment currently stored in two major catchments was estimated using high-resolution LiDAR and geometric reconstructions of depth to bedrock. Seismic reflection data in Moran Bay reveals post-glacial sediment preserved behind a submerged moraine, which isolates the bay from the larger Jackson Lake depocenter. The volume of post-glacial sediment stored in the canyons and bay totals 173.82 ± 19.5336.0 (×10−3 km3), which translates to a catchment-wide sediment production rate of 0.17 ± 0.02 …

Genetic Property Rhetoric And The Public Domain, Dave Fagundes

Texas A&M Journal of Property Law

Among the many themes that illuminate Jorge Contreras’s The Genome Defense, this Essay focuses on property. It considers the rhetorical role played by property in convincing both courts and the public that patenting genetic data was legally and ethically objectionable. This Essay begins by locating property—and public property—as a major theme in the dialogue surrounding the Myriad litigation. It then situates this rhetorical move in the context of property-talk generally, highlighting the distinctiveness of leveraging public rather than private ownership as a means of accessing moral intuitions. Finally, this Essay reflects on what the use of public property rhetoric …

Existential Threats And Deterrence: Japan's Legal Pathway To Enhanced Collective Security In Asia, Nobuhisa Ishizuka

American University International Law Review

With the Japanese Cabinet’s decision in December 2022 to comprehensively upgrade Japan’s security posture, and its rapid build-up of its defense capabilities, Japan’s role in Asia’s security architecture has been undergoing a fundamental shift. This article places Japan’s 2015 Peace and Security Legislation in the context of the U.N. collective security system and argues that its most significant achievement has been to expand Japan’s power to engage more proactively in the Asian collective security order. To date, commentators have focused on the legislation’s role in expanding the Japanese constitution’s limitations on the use of force to permit collective self-defense. This …

Can Prior Censorship Be A Necessary Tool For The Protection Of Human Rights?, Leandro Leo Rebelo

American University International Law Review

Prior censorship is unequivocally interpreted by the Inter-American Human Rights System (“Inter-American System”) as a step too far in moderating expression. Except in the quite narrow circumstances allowed for under Article 13(4) of the American Convention on Human Rights (“ACHR”), the Inter-American System has reiterated that prior censorship is forbidden. However, prior censorship is widely used in social media platforms as a tool of content moderation. Should such techniques be banned, or should more exceptions be allowed in the regulation of speech?
