Intelligent Formation Control Using Orfbls And Adaptive Backstepping Sliding-Mode Control To Address Uncertain Tilting In Multi-Quadrotors During Wind Gusts, Ching-Chih Tsai, Chun-Fu Mao, Kumail Hussain

Journal of Marine Science and Technology–Taiwan

In terms of aerial robotics, stable and precise formation control is a significant challenge for tilting multi-quadrotors during disturbances. This paper proposes a fixed-time formation control strategy for tilting multi-quadrotors to address the effect of external wind gusts. The observer accurately predicts environmental disturbances and an adaptive backstepping sliding-mode control (ABSMC) method with an output recurrent fuzzy broad learning system (ORFBLS) addresses these disturbances within a finite time. ORFBLS dynamically adjusts its structure through a growing ORFBLS structure to allow nodes to be added as needed. The method's stability is validated using Lyapunov stability theory and ensures the convergence of …

Visually Guided Landing System On Ship Deck For Multicopter, Dong-Lin Li, Shih-Kai Lee, Tzu-Hsiang Chou

Journal of Marine Science and Technology–Taiwan

Traditionally, high-value fish have been located at sea using helicopters. However, with advancements in technology, maritime drones have become increasingly important in recent years. Compared to traditional helicopter-based methods, drones offer significantly lower operational costs, making them cost-effective. However, the challenging sea conditions, including strong winds and the swaying motion of vessels, pose significant challenges for drone landings.

This paper proposes a stable approach for multicopter landing on ships at sea, incorporating improved marker detection, enhanced wind resistance control, and more accurate deck motion prediction. In the marker detection phase, we introduce a method to improve the accuracy of ArUco …

Leveraging Virtual Reality And Haptics To Teach Surgical Skills: A Usability Study On Retropubic Midurethral Slings, Lauren Siff, Ginger S. Watson, Jerome Dixon, Moshe Feldman, Franklin Bost, Philippe J. Giabbanelli

VMASC Publications

Traditional methods to learn soft-tissue surgical procedures rely on cadaver labs or patient-based learning, which are costly and geographically limited, and raise ethical questions. Virtual reality (VR) with haptic feedback offers a scalable alternative, but most current platforms emphasize bone-based rather than soft-tissue procedures learned by feel. We developed a VR+haptic simulation for preoperative training of retropubic midurethral sling (MUS) surgery. This study examines the usability of this platform with thirteen expert urogynecologic surgeons and subsequently makes improvements (e.g., in haptics) to evaluate the platform with twelve trainees based on the NASA Task Load Index for workload and a UTAUT-informed …

Using Remote Sensing Technology To Develop A Framework For Improving Hydrologic Models, Marissa Cook

Theses, Dissertations and Capstones

With increased storm intensity due to climate change and urbanization, flash flooding has become an increasingly significant issue globally and regionally. Although the factors influencing urban flash flooding are well-known, there is a growing need for technology to accurately and remotely predict the chance of a flash flood occurring from any given rain event to give people time to prepare. This study aims to use multispectral satellite imagery to provide a framework for improving near real-time flood predictions in an urban area of a high gradient, fourth order stream impacted by flooding. Specifically, we utilize satellite imagery to create the …

This project examines the current operational strategy of the Bonnet Carré Spillway (BCS), a Mississippi River flood-control structure located about 21 miles northwest of New Orleans, Louisiana, and managed by the U.S. Army Corps of Engineers. The BCS is part of the larger Mississippi River and Tributaries Project, a network of levees and control structures designed to minimize flooding from the American plains to southern Louisiana. The spillway is opened when river discharge at New Orleans is forecasted to exceed 1,250,000 cubic feet per second, diverting significant volumes of Mississippi River water into Lake Pontchartrain which subsequently flows into Mississippi …

Maesa Ramentacea Leaf Extract Protects Against Gentamicin-Induced Nephrotoxicity In Wistar Rats By Modulating Renal Oxidative Stress, Inflammation And Apoptosis, Fahmida Akter, Md Shafiqul Islam Sovon, Baizid Hossain, Md Ariful Islam, Subrato Das, Anik Biswas, Md Sohorab Uddin, Md Mahmudul Hasan

Faculty Publications

Background: Gentamicin-induced nephrotoxicity continues to be a significant clinical concern, while effective and safe protective options remain limited. The nephroprotective potential of Maesa ramentacea has not yet been explored. To address this gap, the present study investigated the ethanolic leaf extract of M. ramentacea (MR-LEE) for its effects on gentamicin-induced kidney injury in Wistar rats. Methods: GC-MS profiling was employed to identify bioactive metabolites. Rats were categorised into five groups: control, gentamicin (100 mg/kg), gentamicin combined with silymarin (100 mg/kg), gentamicin combined with MR-LEE (200 mg/kg) and gentamicin combined with MR-LEE (400 mg/kg). Renal biomarkers, oxidative stress indicators, inflammatory and …

From Surfaces To Scaffolds: Tuning Hydrogel Microenvironments To Control Cell-Material Interaction, Tran Truong

Doctoral Dissertations

The last 40 years of in vitro cell and tissue biology have relied heavily on tissue culture plastic (TCPS), which offers high transparency and a simple, user-friendly method for growing adherent cells. Unfortunately, TCPS has limitations, such as its rigidity, which may alter cell shape, disrupt cell signaling, and ultimately affect cell fate. The poor control over the adsorption of proteins to TCPS and the fact that surface chemistry is fixed on this material are only two examples of the limitations that motivate the development of hydrogel-based culturing platforms, during which the mechanical properties, charge, hydrophobicity, and ligand presentation can …

Entrainment And Surfacing Dynamics Of Submerged, Buoyant Turbulent Jets, Zeeshan Saeed

Doctoral Dissertations

Turbulent entrainment (TE) in buoyant jets plays a key role in dispersing environmental contaminants, carrying significant socio-economic implications. For example, the transport of heat and solutes through submarine volcanoes and the discharge of subglacial meltwater crucially affect the marine ecosphere. This, in turn, impacts coastal communities, the supply chains they support, and the broader socio-economic landscape. Therefore, advancing our understanding of how submerged buoyant jets mix and developing remote sensing tools to help monitor their changing status is crucial for devising strategies to mitigate marine-related challenges quickly, economically, and effectively. Therefore, this dissertation has three primary objectives: (I) examine the …

Emotional Complexity In Context: Within-Person Variability In Emotional Granularity, Emotion Covariation, And Emodiversity, Kristen Diann Petagna

Doctoral Dissertations

Key features of emotional complexity include emotional granularity, the ability to identify feelings with precision; emodiversity, the number and evenness of different emotions experienced; and emotion covariation, the tendency to experience positive and negative emotions independently. Prior work has largely treated these features as trait-like. This dissertation examines whether these features are dynamic by investigating how they vary within individuals over time and across contexts. In Chapter 2, participants (N =123) reported their emotions multiple times a day for 6 weeks and completed biweekly assessments of mental health symptoms. Emotional granularity and covariation increased over time, whereas emodiversity decreased, and …

A Dose Of Accountability: Fixing Treaty Enforcement To Combat State Complicity In Transnational Illicit Fentanyl Trafficking, Caitlin Sharma

Vanderbilt Journal of Transnational Law

The international fentanyl crisis underscores significant gaps in treaty enforcement, particularly with state accountability for drug manufacturing and export practices leading to illicit fentanyl trafficking. Despite preventive measures established by United Nations drug conventions, legal loopholes in these provisions impede meaningful cooperation between state parties. This Note uses key countries, including the United States, Canada, Mexico, China, and India, as case studies in both producing and receiving fentanyl and its precursors. It evaluates current proposals to mitigate the crisis, such as enhanced international cooperation and the potential expansion of the International Criminal Court’s jurisdiction. However, these solutions remain insufficient due …

Erie And The Constitution's Constraints On General Law, Anthony J. Bellia Jr., Bradford R. Clark

GW Law Faculty Publications & Other Works

The Constitution of 1787 was the instrument by which the people of the States made a partial and conditional transfer of sovereign authority to a new federal government. To preserve the States’ residual sovereignty, the Constitution established a system of conditional federal supremacy. Specifically, it made the federal government’s ability to displace of state law contingent on compliance with specific structural and procedural safeguards. The Supremacy Clause identifies only three sources of “the supreme Law of the Land”—the Constitution, laws enacted pursuant to it, and treaties made under its authority. For each of these sources of law, the Constitution specifies …

A Variance Decomposition Approach To Inconclusives In Forensic Black Box Studies, Amanda Luby, Joseph B. Kadane

Mathematics and Statistics Faculty Work

In the USA, ‘black box’ studies are increasingly being used to estimate the error rate of forensic disciplines. A sample of forensic examiner participants is asked to evaluate a set of items whose source is known to the researchers but not to the participants. Participants are asked to make a source determination (typically an identification, exclusion, or some kind of inconclusive). We study inconclusives in two black box studies, one on fingerprints and one on bullets. Rather than treating all inconclusive responses as functionally correct (as is the practice in reported error rates in the two studies we address), irrelevant …

Biological Use Of Molybdenum And Tungsten Stems Back To 3.4 Billion Years Ago, Rika Anderson, Aya S. Klos, Morgan S. Sobol, Joanne S. Boden, Eva E. Stüeken, Kurt O. Konhauser, Betül Kaçar

Biology Faculty Work

The biological significance of the transition metal molybdenum (Mo) lies in its function at the catalytic center of several enzymes that drive a wide spectrum of redox reactions underlying global biogeochemical cycles, yet a paradox persists. While modern life ubiquitously relies on Mo, geochemical evidence suggests that its availability in early Earth’s anoxic oceans was extremely limited. Modern organisms can use Mo down to trace levels; however, the rates of Mo-dependent metabolisms slow down when Mo availability decreases, posing fundamental questions about the extent to which changing Mo abundances shaped the evolution of molybdoenzymes, and when early life began harnessing …

Restoring The Wild East: Predicting Public Support For Cougar And Red Wolf Reintroduction In The Eastern United States, Benjamin Ghasemi, Jeremy T. Bruskotter, John A. Vucetich, L. Mark Elbroch, Robyn S. Wilson, Neil H. Carter, Axel Moehrenschlager, Shelby Perry, Joseph W. Hinton

Michigan Tech Publications

Restoring large carnivores to human-dominated landscapes remains ecologically and socially contentious, though reintroduction may offer important benefits where coexistence is possible. Yet, efforts to reintroduce cougars (Puma concolor) and red wolves (Canis rufus) in the Eastern U.S. face major challenges, largely due to human-caused mortality and opposition. We employed the hazard acceptance model and structural equation modeling to investigate the socio-psychological drivers of public support for reintroduction. Survey data were collected from residents of the Eastern U.S. for cougars (n = 2665) and red wolves (n = 3825). For both species, support was positively associated with perceived personal and societal …

Bravo, Júlia Dordal-Soriano, Javier Gilabert, Sophia Bergeler, Celine Lavergne, Gemma Casas, Marisol Manzano, Jordi Garcia-Orellana, Valentí Rodellas

OES Faculty Publications

Submarine groundwater discharge (SGD) is a widely recognized pathway for nutrient transport to coastal systems. Prior studies overlook the unique biogeochemical signatures of different SGD pathways, neglecting their differences in biogeochemical transformations and spatiotemporal factors. Here, we present an integrated assessment of nutrient delivery through three SGD pathways (fresh SGD, long‐scale recirculated SGD, and short‐scale porewater exchange), alongside surface water inputs, to evaluate their seasonality and impact on nutrient dynamics in a coastal lagoon. We conducted five field surveys in March, July, and November 2021, July 2024, and March 2025 in the Mar Menor lagoon, an ecosystem facing severe ecological …

Seasonal And Geologic Controls On Submarine Groundwater Discharge-Derived Nutrient Fluxes To Two Coastal Embayments, Moira Taylor, Joseph J. Tamborski, Aaron Alorda-Kleinglass, Nathaniel Maynard

OES Faculty Publications

Submarine groundwater discharge and porewater exchange are critical but often overlooked sources of nutrients to coastal systems. This study investigates how sediment permeability and summer-winter seasonal dynamics influence the magnitude and biogeochemistry of nutrient fluxes from submarine groundwater discharge and porewater exchange. Reaction rates in the subterranean estuary were used to identify the transformations and drivers of nutrient loading in two geologically distinct embayments in the U.S. East Coast: the highly permeable Peconic Bay estuary (NY), and the surficially fine-grained coastal embayments of the southern Delmarva Peninsula (VA). We applied radium isotope mass balances to distinguish total submarine groundwater discharge …

Social Safety And Social Security: Validating Context-Specific Instruments For Slums, Liss D. Romero, Katherine Palacio, Zacheous Ako Abang, Valeria Silgado, Humberto Llinas, Leidy González, Erika Frydenlund, Daniel Bolivar, Jose J. Padilla

VMASC Publications

Social safety and social security are concepts that help explain a community's well-being by assessing how it manages and mitigate existing, or perceived, risks. However, these terms are often conflated, which can limit understanding, particularly in areas with unstable living conditions. This study explores both concepts in the context of residents living in slums. As the number of displaced people grows, slums and informal settlements are becoming increasingly common worldwide, making it essential to clarify these concepts. Residents of slums face numerous hazards, including crime, violence, inadequate housing, overcrowding, and limited access to essential services. To measure social safety and …

Socio-Spatial Patterns Of Suicide Mortality In The United States, Kushagra Tiwari, M. Amin Rahimian, Marie-Laure Charpignon, Philippe J. Giabbanelli, Praveen Kumar

VMASC Publications

Suicides cause more than 49,000 deaths per year in the United States, including 55% associated with the use of a firearm. Across states and counties in the US, suicide mortality exhibits substantial geographical and sociodemographic heterogeneity. However, the role of large-scale social networks in shaping this variation remains underexplored. To assess how both the risk of suicide mortality and the effect of firearm restriction policies propagate through inter-county social ties, we integrate data on county-level suicide mortality (2010–2022) and the Facebook Social Connectedness Index (SCI), a continuous measure of the strength of social ties between counties used to derive weighted …

Severity And Duration-Dependent Aortic Stiffening In A Rabbit Coarctation Model Identifies Constitutive Material Parameters As Promising Regional Biomarkers For Hypertension Progression, Arash Ghorbannia, Jamasp Azarnoosh, John F. Ladisa Jr.

VMASC Publications

Coarctation of the aorta (CoA) alters hemodynamics and drives regional remodeling, yet the influence of severity and duration on constitutive properties is undefined. We quantified mechanical responses from CoA to identify constitutive parameters capturing stiffening across clinical severities and durations. Mild (≤ 12 mmHg), intermediate (13–20 mmHg), and severe (> 20 mmHg) CoA was created in rabbits for short, long, and prolonged durations (~ 1, 3, or 22 weeks, respectively). Stress–stretch curves from proximal and distal regions were fit with multiple constitutive models (Linear Elastic, Neo-Hookean, Yeoh, Ogden, Mooney–Rivlin, Holzapfel). Model performance was evaluated by normalized RMSE and R², with …

Machine Learning Classification Of Prostate Cancer Genomic Sequences Using K-Mer And Sequence-Derived Features, Kuldeep Rawat, Hirendra Nath Banerjee, Jamie Noble, Saa Naudia Deloatch, Satyendra Banerjee, Sachin Shetty, Soumya Banerjee

VMASC Publications

Prostate cancer disproportionately impacts African American men, who experience significantly higher mortality rates and earlier disease onset than other populations. Current diagnostic approaches, including prostate-specific antigen testing and biopsy, lack sufficient specificity and sensitivity, underscoring the need for accurate, molecular-level classification tools. This paper presents a machine learning framework for binary classification of genomic DNA sequences as cancerous or healthy. A dataset of 1684 FASTA-formatted sequences obtained from the National Library of Medicine - GenBank was analyzed, with 1662 sequences retained after quality control filtering. Feature engineering yielded 67 attributes, including GC content, Shannon entropy, sequence length, and trinucleotide k-mer …

Different Destinations: Clarifying And Addressing Pipeline Problems For Women In Academic Archaeology, Scott R. Hutson, Jaycee Castro, Bruno Athie Teruel

Anthropology Faculty Publications

In STEM fields, women tend to leak out of the pipeline to the professoriate. In archaeology, however, robust databases and chronological control reveal that there is no leakage from earning a PhD to tenure-track positions. Nor is there a leak from assistant professor to associate professor. Nevertheless, men get hired as faculty in PhD programs more often than women. This is important because PhD programs are research-intensive and train future leaders. Furthermore, women PhD students have women as advisers more than often men and report advantages to this arrangement. Yet with fewer women faculty in PhD programs, women mentors are …

The Morphological Affinities Of The Fossil Cranium From Kabua, Kenya, Abel Marinus Bosman, Laura Tabitha Buck, Hugo Reyes-Centeno, Marta Mirazón Lahr, Chris Stringer, Rainer Grün, Qingfeng Shao, Katerina Harvati

Anthropology Faculty Publications

Our current understanding of the origins of Homo sapiens is limited, in part, by the fragmented fossil record from Late Pleistocene and early Holocene Africa. Here, we re-examine the Kabua 1 cranium, an enigmatic and little-studied Kenyan fossil discovered in the 1950s. We compare virtual reconstructions created previously by our team with a wide range of Middle Pleistocene to Early Holocene fossils and recent African H. sapiens crania to assess Kabua 1's morphological affinities. We also provide a conservative new Uranium-series minimum date of 64.4 ± 5.4 ka. Our results highlight Kabua 1's broad similarity to derived H. sapiens, both …

A Qualitative Study: How Does The Underrepresentation Of Black American Contributions To American Society In K-12 Curricula Affects Black Students' Self-Perception?, Deniece M. Rogers

Theses and Dissertations from DePaul University

This qualitative phenomenological study examined how the underrepresentation of Black American history in K–12 curricula influences individuals’ understanding of American society, identity, and cultural belonging. Using open-ended questionnaires distributed via Qualtrics, thirty-seven participants reflected on their educational experiences, the extent to which Black American history was included, and how its omission shaped their self-perception and social awareness. Guided by Critical Race Theory (CRT) and The 1619 Project, the study was organized around six a priori themes identified in existing scholarship: Awareness of Historical Omission, Identity and Self-Perception, Social and Cultural Impact, Reactions to the Education System, Emotional Responses, and Broader …
