Automated Segmentation And Structural Remodeling Analysis Of Ipsc-Derived Cardiomyocyte, Bahareh Bahmani

McKelvey School of Engineering Graduate Student Theses & Dissertations

Cardiomyopathy is a disease of the heart muscle that can change cell structure, protein organization, and overall heart function. Some forms of cardiomyopathy are genetically inherited, including Hypertrophic Cardiomyopathy (HCM), the most common inherited cardiomyopathy affecting nearly 1 in 200 individuals1,2, and Desmin-Related Cardiomyopathy (DRM), a rarer disease that affects approximately 1 in 2000 individuals3. Changes in cardiomyocytes’ cellular structure define cardiomyopathies, and these changes are typically studied with fluorescence microscopy. However, manual image analysis is slow, labor-intensive, and often gives inconsistent results, especially when images are analyzed by non-experts. This thesis presents an automated computational framework for analyzing cardiomyocyte …

Improving Semantic Precision In Text-To-Image Diffusion Models Via Latent-Space Optimization And Semantically-Parsed Evaluation, Mohammad Rouie Miab

McKelvey School of Engineering Graduate Student Theses & Dissertations

Text-to-image diffusion models can produce visually impressive images from natural-language prompts, but they often fail to satisfy the detailed semantic constraints expressed in compositional prompts. Typical failure modes include omitted objects, merged entities, incorrect quantities, incorrect attribute binding, and leakage of one entity's attributes onto another. This thesis studies the problem of semantic precision in text-to-image generation: how faithfully a generated image satisfies the structured meaning of its prompt.   The thesis makes two linked contributions. First, it presents a training-free inference-time refinement method for diffusion-based image generation. The method operates directly in latent space during denoising and uses noun-phrase-aware cross-attention …

Largest 2-Regular Subgraphs In Complete S-Partite Graphs, Yiyang Jiang

McKelvey School of Engineering Graduate Student Theses & Dissertations

In this thesis, we focus on the class of complete $S$-partite graphs, for $S$ an undirected graph possibly with self-loops, and address the problem of finding largest $2$-regular subgraphs of these graphs, which can be formulated as an integer linear program. Roughly speaking, a complete $S$-partite graph is obtained by replacing every single node of $S$ with a number of nodes, preserving the edge/non-edge relations of $S$. Our motivation in studying largest $2$-regular subgraphs is rooted in the structural systems theory, particularly in the problem of finding largest subnetworks that can sustain controllability or asymptotic stability of the corresponding subsystems. …

Case Report: Anaphylaxis-Induced Cardiac Arrest Leading To Multiorgan Failure, Dhruvin Patel, Russell Mordecai, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Anaphylaxis is a severe, life-threatening hypersensitivity reaction that can rapidly progress to cardiovascular collapse and cardiac arrest. Cardiac arrest due to anaphylaxis is uncommon but associated with significant morbidity and mortality. Survivors often face complex critical care courses, including multiorgan dysfunction and challenges in neurologic prognostication following hypoxic-ischemic brain injury.

Case Report: Adult Distal Lleal Perforation Mimicking Meckel's Diverticulum, Dip Patel, Wayne Tamaska, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Meckel’s diverticulum is the most common congenital anomaly of the gastrointestinal tract, but clinically significant disease in adulthood is uncommon and often difficult to diagnose before surgery. In adults, symptomatic Meckel’s most often presents with obstruction, bleeding, or inflammation, and cross-sectional imaging may not clearly distinguish it from other distal ileal processes.

We report the case of a 35-year-old man who presented with several days of fever, abdominal pain, vomiting, and diarrhea. CT imaging suggested a complicated distal ileal diverticular process, most concerning for perforated Meckel’s diverticulum with an adjacent abscess. He underwent emergent small bowel resection and abscess drainage. …

Arrhythmic Syncope And Brugada Syndrome: Critical Identification Of High-Risk Patterns At The Ed Frontline, Kristine Rubi, Brittany Fera, Kelsey Murray, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Brugada Syndrome (BrS) is a premier cause of sudden cardiac death (SCD) in structurally normal hearts, particularly in Southeast Asia (SEA) where it is historically recognized as Sudden Unexplained Nocturnal Death Syndrome (SUNDS). We report the case of a 55-year-old male of Vietnamese descent who presented to the emergency department (ED) after a sudden, non-prodromal syncopal episode at rest. The event was significant for urinary incontinence and diaphoresis, classic red flags for arrhythmic syncope. Bedside electrocardiogram (EKG) demonstrated the pathognomonic Type 1 coved ST-segment elevation in leads V1 and V2. This symptomatic presentation following a six-year "follow-up gap" since a …
