Latinos And Complicated Grief: An Analysis On The Impacts Of A College Campus On Grief And Bereavement, Mark Jared Velasco Gonzalez

Sociology Undergraduate Senior Theses

Grief and bereavement are under researched topics within Latino populations, and even more so among Latino college students. Much of the existing literature is also focused on quantitative studies that are said to provide higher quality evidence than qualitative studies, with very few being conducted on college campuses. Garcini et al published a systemic review in 2021 on bereavement among widowed Latinos in which most studies were conducted using quantitative methods. Further, only 4 of the 19 studies analyzed were based solely on Latino communities. Falzarano et al. also published a literature synthesis in 2022 which focused on the broader …

Diagnosis, Treatment, Genetic Basis, And Prevention Of Canine Hip Dysplasia, Nathaniel R. Woody

Senior Honors Theses

Canine Hip Dysplasia (CHD) is a genetic disorder that results in an improper formation of the hip joint. This results in joint laxity, which eats away at the cartilage of the acetabulum. CHD causes arthritis, making normal walking painful for dogs. CHD is the result of many different genes and mutations working together. The best way to prevent CHD in dogs is to selectively breed animals who are not genotypic for the mutation. For dogs that already carry the mutation responsible for CHD the earlier the diagnosis and treatment the better chance they have of a full pain free life …

A Semiclassical Model Of The Immediate Temperature Distribution Surrounding The Track Of Heavy Ions With Therapeutic Energies, Martin Rädler, Niayesh Afshordi, Reza Taleei, Katia Parodi, Ramin Abolfath, Julie Lascaud

Department of Radiation Oncology Faculty Papers

Objective. Spikes of high temperature and pressure are created in the vicinity of heavy ions, especially at the Bragg peak. The expected subsequent thermoacoustic effects are however not well understood. In particular, the distribution of the densely packed primary interactions has not been considered in molecular dynamics (MDs) simulations or shock wave solutions. In this work, we derive a dedicated model to describe the primary interactions and their radial distribution, applicable to the modeling of acoustic and thermodynamic effects at the nanoscale. Approach. Starting from first principles, we assemble a semiclassical model of the energy loss of the primary heavy …

Design And Optimization Of Low-Loss, High-Gain Metamaterial-Based Log-Periodic Dipole Array Antenna For Full Ka-Band Coverage, Mohamed El Moniar, Ahmed Abd El Hady, Yasser Ismail, Nihal Areed

Turkish Journal of Electrical Engineering and Computer Sciences

This work describes a microstrip log-periodic dipole array (MLPDA) antenna that uses metamaterials and operates across the whole Ka-band. The suggested MLPDA antenna layout provides a wide bandwidth with fewer dipole elements than traditional MLPDA antennas while maintaining the same resonance frequencies. To reduce size while covering a wide operational spectrum, the antenna design includes bending dipoles as radiating elements, as well as an incomplete ground plane. Furthermore, the proposed MLPDA antenna’s energy loss has been reduced while boosting its signal strength (gain) by inserting a metamaterial-based structure in front of it at a certain distance and on the same …

A Methodology For Nuclei Segmentation In H&E Images Using Efficientnetb7 Guided U-Net And Multiple Data Augmentation Strategies, Furkan Atlan, Emrah Hançer

Turkish Journal of Electrical Engineering and Computer Sciences

Automating nuclei segmentation in Hematoxylin and Eosin (H&E) stained images is crucial for advancing computational pathology. Despite significant research, challenges such as overlapping nuclei, varying scanner resolutions, and diverse nuclear morphologies continue to hinder segmentation accuracy. In this paper, we propose a deep-learning based methodology that integrates multiple data augmentation strategies with a U-Net architecture enhanced by the EfficientNetB7 encoder. To enhance generalization, we train the model using a combined dataset from MoNuSeg2018, CPM-17, and CoNSeP, exposing it to diverse staining techniques and tissue types. We then evaluate its robustness on the unseen CryoNuSeg dataset, which consists of fully annotated …

The Effect Of God's Image On The Self Concept Of Pastors' Kids (Pks), Dedra Mikesha Forbes

Doctoral Dissertations and Projects

This study explores whether and to what extent the self-concept of Pastor’s Kids (PKs) is affected by their image of God. The effect of God's image is mediated by stress. Previous research has shown that the pressures of living up to expectations have resulted in mental health disorders and emotional disturbances among PKs that manifest as depression and anxiety. Researchers have found that depression and anxiety often result from stress and stressors experienced by PKs, with types of stress that include harm, threat, and challenge. Such stressors are usually derived from pressures to fulfill familial, church, and peer expectations (Pond, …

Fired And Fractured: An Analysis Of Broken Ceramics, Evan Mcguire

Honors Projects

How does the construction of a ceramic object affect how it breaks? How does the force applied affect this break? These questions are based on my first-hand observations of the multitude of ceramic fragments found in different states of decay at archaeological sites. To answer these questions, I created samples that imitate ancient ceramics and then broke them in different ways. I then analyzed the fracture surfaces and looked for evidence of weak points in the objects. Pieces that were hit by a blunt force, such as a hammer, had radial fractures that formed along paths that had clusters of …

Collins, Theresa A. Freeman, Ryan E. Tomlinson

Department of Orthopaedic Surgery Faculty Papers

Debilitating pain is the primary clinical feature of osteoarthritis (OA) that drives the enormous healthcare costs. Osteoarthritis-related pain is often treated with non-steroidal anti-inflammatory drugs (NSAIDs), which effectively relieve pain and inflammation by inhibition of prostaglandin synthesis. Antibodies directed against nerve growth factor (NGF) were tested some time ago as an alternative potential analgesic for musculoskeletal pain, including osteoarthritis-related pain. Unfortunately, clinical development of these drugs was put on hold due to adverse outcomes - primarily rapidly progressive osteoarthritis. Both prostaglandin synthesis and NGF have been implicated as critical mediators of strain adaptive bone remodeling, which may play a role …

How Experts View The Legal System's Use Of Scientific Evidence, Shari Seidman Diamond, Richard Lempert

Articles

Legal scholars and courts frequently write about how scientific evidence is vetted and presented in legal proceedings, but the views of experts themselves have received little attention. Our research aims to fill that gap. This paper reports some of what we learned from a series of surveys we conducted, beginning with a survey in 2016 of scientists who had been elected to membership in the American Academy of Arts and Sciences.3 Subsequent surveys were directed to subscribers of the journal Science who identified as scientists and engineers and to self-identified experts who advertised their availability as experts to lawyers or …
