Role Of Fluid-Structure Interactions In Mechanosensation During Hovering Flapping Flight, Menglong Lei, Chengyu Li

Faculty Scholarship

Insect wings, known for their intricate structure and function, inherently deform during flapping motion. These deformations can be classified into chordwise cambering, spanwise bending, and root-to-tip twisting, arising from non-uniform venation distribution, aerodynamic loading, and wing inertia. Crucially, such deformations play a vital role in enhancing both aerodynamic performance and mechanosensory function. To investigate the complex interplay between wing structure, unsteady aerodynamics, and mechanosensation, we developed a fully coupled three-dimensional fluid-structure interaction (FSI) solver. This framework integrates an in-house Navier-Stokes equations solver for resolving the flow field with the open-source Vega FEM code to solve the solid structure dynamics. Our …

Assessing Implications Through General Strain Theory: Comparative Analysis Of Crime Rates In Flint And Pontiac Michigan, Jennifer Harrison

Honors Projects

Flint, Michigan suffered a city water change from the Great Lake’s Lake Huron water pipeline to an old system using the Flint River as the main source of water (Reuben, et al., 2022). The change took place in an effort to make budget cuts (Denchak, 2024). The switch occurred before checking the safety of the pipes, which were severely corroded (Reuben, et al., 2022). Lead poisoning and Legionnaires disease spread through the Flint community and the water was visibly not safe for use (Reuben, et al., 2022). The people of Flint experienced stress that they could not control. They feared …

Duncan NRI Faculty and Staff Publications

Background: Genome-wide association studies (GWAS) of Alzheimer's disease (AD) have identified a plethora of risk loci. However, the disease variants/genes and the underlying mechanisms have not been extensively studied.

Methods: Bulk ATAC-seq was performed in induced pluripotent stem cells (iPSCs) differentiated various brain cell types to identify allele-specific open chromatin (ASoC) SNPs. CRISPR-Cas9 editing generated isogenic pairs, which were then differentiated into glutamatergic neurons (iGlut). Transcriptomic analysis and functional studies of iGlut co-cultured with mouse astrocytes assessed neuronal excitability and lipid droplet formation.

Results: We identified a putative causal SNP of CLU that impacted neuronal chromatin accessibility to transcription-factor(s), with …

Understanding Practices And Perceptions Of Teaching Sexual Pleasure In Undergraduate Anatomy & Physiology, Julia M. Bogunia

Honors Capstones

It is well established that sexual health is a crucial component of individual health and wellbeing. The WHO defines sexual health with emphasis on the equal importance of positive sexual experiences and absence of negative sexual health outcomes (WHO, 2006). In the classroom, instructors play a vital role in helping students learn, such as those heading towards health fields. The current study investigated what instructors’ practices and perceptions of teaching sexual pleasure are in undergraduate A&P courses. We used the Woodbury and Gess-Newsome’s Teacher-Centered Systemic Reform Model as a framework and adapted for the context of sexual pleasure. Six semi-structured …

Heterogeneous Condensation On Simplified Viral Envelope Protein Structures, Kawkab Ahasan, Han Hu, Pranav Shrotriya, Todd A. Kingston

Mechanical Engineering Faculty Publications and Presentations

Elucidating the mechanisms of heterogeneous condensation on viral and bacterial envelopes is crucial for understanding biothreat transport phenomena and optimizing capture efficiency in condensation-based detection devices. We investigate the impact of viral envelope geometric parameters [e.g., surface structure pitch-to-diameter ratio (p/d)] due to protruding glycoproteins and surface wettability [via liquid-solid interaction intensity (f)] on heterogeneous condensation using molecular dynamics simulations. Complex glycoprotein structures were modeled as cylindrical pillars to analyze condensation rates and active surface areas across a range of p/d ratios (1.0, 1.2, 1.3, 1.7, 2.0, and infinity) and contact angles (theta = 15 degrees, 75 degrees, and 105 …

A Sumo-Interacting Motif In The Guanine Nucleotide Exchange Factor Epac1 Is Required For Subcellular Targeting And Function, Jason E Lee, Si Nie, Christopher J Bley, André Hoelz, Xiaodong Cheng

Faculty, Staff and Students Publications

Exchange protein directly activated by cAMP (EPAC1), a multifunctional intracellular cAMP receptor, dynamically localizes to various cellular loci, engaging with diverse molecular partners to maintain cellular homeostasis. The study investigates the role of the SUMO interacting motif (SIM) in the subcellular targeting and cellular functions of EPAC1. It reveals that the SIM is a critical structural element for EPAC1's association with RanBP2/Nup358, a nucleoporin of the cytoplasmic filament component of the nuclear pore complex (NPC). Mutational disruption of EPAC1 SIM interferes with EPAC1's ability to activate its canonical effectors, small GTPases, Rap1 and Rap2, and non-canonical functions, such as the …

Retracted: Data Envelopment Analysis Using Stochastic Frontier Analysis And Bootstrap Confidence Intervals, Fahad F. Alqahtani

Iraqi Journal for Computer Science and Mathematics

Evaluating company growth potential has moved away from traditional financial focused ratios and ratios analysis that has origins in the early twentieth-century economics. However, these conventional methods might not be accurate in measuring such efficient factors as this combined proposed framework of Data Envelopment Analysis (DEA) and improved mathematical models do. The present research focuses on the prospect of growth of companies through evaluating the performance of 40 DMUs in terms of efficiency DEA and MMTs. DEA is used to determine the efficient DMUs while SFA underline the factors such as investment on research and development, effective marketing strategies and …

A Hybrid Technique For Approximating The Solution Of Fractional Order Partial Integro-Differential Equations, Ahmed K. Mohsin, Fajir A. Abdulkhaleq, Osama H. Mohammed

Iraqi Journal for Computer Science and Mathematics

In this paper, we discuss the numerical solution of fractional order partial integro-differential equations. The type of fractional derivative used is a Caputo derivative. The method proposed in this paper known as transform optimal perturbation iteration method. This method combines the optimal perturbation iteration method and the Laplace transform in order to converge to the exact solution. The proposed method is highly efficient and provides the means of controlling the approximate solutions convergence. Illustrative examples prove that the suggested approach is very accurate when compared with the exact solution and the results of the existing methods.

Fountain, Sadaf Azadehfar

Theses and Dissertations

This thesis investigates the intersections of water, power, identity, and architecture through the lens of colonial and postcolonial landscapes, focusing particularly on Persian gardens and fountain sculptures. Drawing on historical, cultural, and symbolic frameworks, the study explores how water systems embody both practical and spiritual roles, positioning water as a force of control, resistance, and regeneration. Central to this work are analyses of arches and garden designs, which serve as architectural metaphors for cosmic harmony, community gathering, and contested space. Through a combination of visual analysis, historical research, and personal artistic practice—including ceramic sculptures and multimedia installations—this thesis traces the …
