Political Default. The Implications Of Weaponizing Global Financial Infrastructure, Lev E. Breydo

Faculty Publications

In response to Russia’s unlawful invasion of Ukraine, the U.S. has led a broad-based global coalition to punish the aggressor with an “unprecedented” sanction regime. Those measures have targeted “the Russian government’s basic tools to manage its macroeconomy,” with a particular emphasis on its sovereign debt. That concerted focus, as this Article empirically demonstrates through analysis of bond and credit default swap data, ultimately resulted in Russia’s first foreign currency debt default in over a century — despite the nation’s ability and seeming willingness to pay.

Notwithstanding aptly-deserved “just deserts” considerations, a forced — or “political” — Russian sovereign debt …

Misogynistic Extremism: A Scoping Review, Robin O'Hanlon, Frederick L. Altice, Roy Ka-Wei Lee, Jack Laviolette, Gloria Mark, Orestis Papakyriakopoulos, Koustuv Saha, Munmun De Choudhury, Navin Kumar

Publications and Research

In recent years, the concept of “misogynistic extremism” has emerged as a subject of interest among scholars, governments, law enforcement personnel, and the media. Yet a consistent understanding of how misogynistic extremism is defined and conceptualized has not yet emerged. Varying epistemological orientations may contribute to the current conceptual muddle of this topic, reflecting long-standing and on-going challenges with the conceptualization of its individual components. To address the potential impact of misogynistic extremism (i.e., violent attacks), a more precise understanding of what this phenomenon entails is needed. To summarize the existing knowledge base on the nature of misogynistic extremism, this …

Futures On Dry Ground: Anthropology And Coastal Planning, Theodore Hilton, Sheehan Moore

Publications and Research

Around the world, governments, industry, and other actors are creating plans to save coasts from environmental crisis. Louisiana is one prominent example: levees and other measures protect oil and gas infrastructure from inundation as the wetlands buffer rapidly erodes—in large part due to that same industry. The state’s primary answer to land loss is a $50 billion Coastal Master Plan. To illuminate such responses in Louisiana and globally, this article reviews emerging literature and frames an anthropology of coastal planning around three themes: (1) novel orientations toward time and space, (2) the reproduction of power and capital in the name …

Changes To Sea Surface Temperatures And Vertical Wind Shear And Their Influence On Tropical Cyclone Activity In The Caribbean And The Main Developing Region, Keneshia Hibbert, Equisha Glenn, Thomas M. Smith, Jorge E. González-Cruz

Publications and Research

Sea surface temperatures and vertical wind shear are essential to tropical cyclone formation. TCs need warm SSTs and low shear for genesis. Increasing SSTs and decreasing VWS influences storm development. This work analyzes SST and VWS trends for the Caribbean, surrounding region, and the Atlantic hurricane main developing region from 1982–2020. Storm intensity increases significantly during this period. Annual and seasonal trends show that regional SSTs in the MDR are warming annually at 0.0219 °C yr⁻¹ and, per season, 0.0280 °C yr⁻¹. Simultaneously, VWS decreases during the late rainfall season, at 0.056 m/s yr⁻¹ in the …

Distinctions Between Choroidal Neovascularization And Age Macular Degeneration In Ocular Disease Predictions Via Multi-Size Kernels Ξcho-Weighted Median Patterns, Alex Liew, Sos Agaian, Samir Benbelkacem

Publications and Research

Age-related macular degeneration is a visual disorder caused by abnormalities in a part of the eye’s retina and is a leading source of blindness. The correct detection, precise location, classification, and diagnosis of choroidal neovascularization (CNV) may be challenging if the lesion is small or if Optical Coherence Tomography (OCT) images are degraded by projection and motion. This paper aims to develop an automated quantification and classification system for CNV in neovascular age-related macular degeneration using OCT angiography images. OCT angiography is a non-invasive imaging tool that visualizes retinal and choroidal physiological and pathological vascularization. The presented system is based …

Quantity Of Questing Black-Legged Ticks And Associated Micro-Scale Environmental Data Collected From Four Suburban Parks Near New York City, Shipeng Sun, Chong Di, Li Li, Brian Sulkow, Weigang Qiu

Publications and Research

During 2017 and 2018, we collected the quantity of questing black-legged ticks (Ixodes scapularis), also known as deer ticks, in 124 sampling sites of 5m by 5m in four state parks—Caumsett State Historic Park, Connetquot River State Park, Rockefeller State Park, and Fire Island National Seashore—around New York City. The black-legged tick is the primary vector for the spirochete Borrelia burgdorferi, the pathogen of Lyme disease, in Northeastern United States. Using the flagging method, we collected and counted the numbers of adult and nymphal black-legged ticks at each site. Along with these quantities, we also recorded the …

Automated Morphological Phenotyping Using Learned Shape Descriptors And Functional Maps: A Novel Approach To Geometric Morphometrics, Oshane O. Thomas, Hongyu Shen, Ryan L. Raaum, William E. H. Harcourt-Smith, John D. Polk, Mark Hasegawa-Johnson

Publications and Research

The methods of geometric morphometrics are commonly used to quantify morphology in a broad range of biological sciences. The application of these methods to large datasets is constrained by manual landmark placement limiting the number of landmarks and introducing observer bias. To move the field forward, we need to automate morphological phenotyping in ways that capture comprehensive representations of morphological variation with minimal observer bias. Here, we present Morphological Variation Quantifier (morphVQ), a shape analysis pipeline for quantifying, analyzing, and exploring shape variation in the functional domain. morphVQ uses descriptor learning to estimate the functional correspondence between whole triangular meshes …

Adaptive Single Low-Light Image Enhancement By Fractional Stretching In Logarithmic Domain, Thaweesak Trongtirakul, Sos S. Agaian, Shiqian Wu

Publications and Research

Low-light image enhancement is a challenging task that aims to improve the visibility and quality of images captured in dark environments. However, existing methods often introduce undesirable artifacts such as color distortion, halo effects, blocking artifacts, and noise amplification. In this paper, we propose a novel method that overcomes these limitations by using the logarithmic domain fractional stretching approach to estimate the reflectance component of the image based on the improved Retinex theory. Moreover, we apply a simple adaptive gamma correction algorithm to the Lab color-space to adjust the brightness and saturation of the image. Our method effectively reduces the …

Lead Induced Differences In Bone Properties In Osteocalcin +/+ And −/− Female Mice, G. Yildirim, W. C. Budell, O. Berezovska, S. Yagerman, S. S. Maliath, P. Mastrokostas, S. Tommasini, T. L. Dowd

Publications and Research

Lead (Pb) toxicity is a major health problem and bone is the major reservoir. Lead is detrimental to bone, affects bone remodelingand is associated with elderly fractures. Osteocalcin (OC) affects bone remodeling, improves fracture resistance and decreases with age and in some diseases. The effect of lead in osteocalcin depleted bone is unknown and of interest. We compared bone mineral properties of control and Pb exposed (from 2 to 6 months) femora from female adult C57BL6 OC+/+ and OC−/− mice using Fourier Transform Infrared Imaging (FTIRI), Micro-computed tomography (uCT), bone biomechanical measurements and serum turnover markers (P1NP, CTX). Lead significantly …

Feeling Analogue: Using Modular Synthesizers, Designing Synthesis Communities, Eliot Bates

Publications and Research

When Harald Bode nominally invented the modular synthesiser in 1960, it was not yet clear whether it was a musical instrument or a less-defined form of studio-sited audio technology (Subotnik 1970). Much of the technology, from the interface design to the specific parts, was shared with nonmusical test and measurement equipment. Sixty years later, hardware modular synthesis is used not just for musical creation but for noise, sound art and data sonification/visualization. Through an ethnographic study of the design and use of the Eurorack modular synthesis format, and of modular synthesis maker and user communities spread through North America, Europe …

Ecological-Niche Modeling Reveals Current Opportunities For Agave Dryland Farming In Sonora, Mexico And Arizona, Usa, Hector G. Ortiz-Cano, Robert Hadfield, Teresa Gomez, Kevin Hultine, Ricardo Mata-Gonzalez, Steven L. Petersen, Neil C. Hansen, Michael T. Searcy, Jason Stetler, Teodoro Cervantes-Mendivil, David Burchfield, Pilman Park, J. Ryan Stewart

Faculty Publications

For centuries, humans occupying arid regions of North America have maintained an intricate relationship with Agave (Agavoideae, Asparagaceae). Today Agave cultivation, primarily for beverage production, provides an economic engine for rural communities throughout Mexico. Among known dryland-farming methods, the use of rock piles and cattle-grazed areas stand out as promising approaches for Agave cultivation. Identifying new cultivation areas to apply these approaches in Arizona, USA and Sonora, Mexico warrants a geographic assessment of areas outside the known ranges of rock piles and grasslands. The objective of this study was to predict areas for dryland-farming of Agave and develop models to …

2020-Current year OA Pubs

INTRODUCTION: Several evidence-informed consent practices (ECPs) have been shown to improve informed consent in clinical trials but are not routinely used. These include optimizing consent formatting, using plain language, using validated instruments to assess understanding, and involving legally authorized representatives when appropriate. We hypothesized that participants receiving an implementation science toolkit and a social media push would have increased adoption of ECPs and other outcomes.

METHODS: We conducted a 1-year trial with clinical research professionals in the USA (

RESULTS: Participants who engaged more with the toolkit were more likely to have tried to implement an ECP during the trial …

Low-Fidelity Design Optimization And Parameter Sensitivity Analysis Of Tilt-Rotor Evtol Electric Propulsion Systems, Tyler Critchfield, Andrew Ning

Faculty Publications

Urban air mobility requires a multidisciplinary approach to tackle the important chal- lenges facing the design of these aircraft. This work uses low-to-mid fidelity tools to model rotor aerodynamics, blade structures, vehicle aerodynamics, and electric propulsion for a tilt-rotor electric vertical takeoff and landing (eVTOL) aircraft. We use gradient-based design optimization and extensive parameter sensitivity analysis to explore the design space and complex tradeoffs of tilt-rotor distributed electric propulsion systems.

Sparsity For Gradient-Based Optimization Of Wind Farm Layouts, Benjamin T. Varela, Andrew Ning

Faculty Publications

Optimizing wind farm layouts is an important step in designing an efficient wind farm. Optimizing wind farm layouts is also a difficult task due to computation times increasing with the number of turbines present in the farm. The most computationally expensive part of gradient- based optimization is calculating the gradient. In order to reduce the expense of gradient calculation, we performed a study on the use of sparsity in wind farm layout optimization. This paper presents the findings of the sparsity study and provides a method to use sparsity in wind farm layout optimization. We tested this sparsity method by …

A Coupled Source Panel, Actuator Line, And Viscous Vortex Particle Method In An O(N) Scheme, Ryan Anderson, Andrew Ning

Faculty Publications

Wake interactions play a significant role in aerodynamics. However, common modeling approaches are either expensive or lack fidelity, making them unreliable or difficult to use in the design process. The vortex particle method can capture the relevant physics effectively, but imposing boundary conditions with solid surfaces in a computationally efficient way is challenging. We explore two possible methods of imposing solid surface boundary conditions of vortex particle simulations. The first, a novel variation on a pure particle approach, is easy to implement but is moderately expensive, and suffers from some numerical instability. The second, source panels accelerated with a fast …

Aerostructural Predictions Combining Fenics And A Viscous Vortex Particle Method, Ryan Anderson, Andrew Ning, Ru Xiang, Sebastiaan P. C. Van Schie, Mark Sperry, Darshan Sarojini, David Kamensky, John T. Hwang

Faculty Publications

Electric Vertical Takeoff and Landing (eVTOL) aircraft experience complex, unsteady aerodynamic interactions between rotors, wings, and fuselage that can make design difficult. We introduce a new framework for predicting aerostructural interactions. Specifically, we demonstrate the coupling of a finite element solver with Reissner-Mindlin shell theory for computing deflections and a viscous vortex particle for capturing wakes. We perform convergence studies of the aerodynamics and the coupled aerostructural model. Finally, we share some preliminary results of the dynamic aeroelastic response of Uber’s eCRM-002 main wing, and share some qualitative observations.

Plea Bargains: Efficient Or Unjust?, Jeffrey Bellin, Erin Blondel, John Flynn, Elana Fogel, Anjelica Hendricks, Carissa Byrne Hessick

Faculty Publications

The vast majority of state and federal cases end in plea bargains. The practice has eased backlogs and may benefit some defendants — but the trade-offs, some say, are too steep. Is there a better way?

The Tesla Meets The Fourth Amendment, Adam M. Gershowitz

Faculty Publications

Can police search a smart car’s computer without a warrant? Although the Supreme Court banned warrantless searches of cell phones incident to arrest in Riley v. California, the Court left the door open for warrantless searches under other exceptions to the warrant requirement. This is the first article to argue that the Fourth Amendment’s automobile exception currently permits the police to warrantlessly dig into a vehicle’s computer system and extract vast amounts of cell phone data. Just as the police can rip open seats or slash tires to search for drugs under the automobile exception, the police can warrantlessly …

Readability of each website was determined using the Flesch-Kincaid grade level (FKGL) readability formula within the readable tool. …

Implications Of Physical Fault Injections On Single Chip Motes, Sara Faour, Mališa Vučinić, Filip Maksimovic, David Burnett, Paul Muhlethaler, Thomas Watteyne, Kristofer Pister

Electrical and Computer Engineering Faculty Publications and Presentations

Single-chip motes are wireless sensor nodes that integrate computation, communication, power and sensing on a single chip. We consider the security threats these novel devices are subject to when employed in safety-critical applications. Fault injection attacks are a prominent form of physical attacks that pose a threat to the normal and secure functioning of targeted devices, potentially compromising their intended behavior. These attacks have been studied mainly on commercial off-the-shelf devices which rely on external components such as crystal oscillators and passives. Such external components are absent from single-chip motes, resulting in a uniquely different attack surface compared to commercial …

Understanding The Role Of Online Teaching Assistants In Student Engagement, Sara H. Tuiloma, Charles R. Graham

Faculty Publications

In this paper, we examine how online teaching assistants (OLTAs) interact with students in terms of affective, behavioral, and cognitive support and the influence of OLTA training on these interactions. Through a thematic network analysis, using a tracking instrument and semi-structured interviews with 10 OLTAs, we examined how online university students are supported based on the quantity and quality of interactions with OLTAs, and how training contributes to interactions. Our research addressed two key questions: (1) How do OLTAs support learners in the quantity and quality of interactions? and (2) How does OLTA training around affective and behavioral support influence …

Characterization Of High-Gamma Activity In Electrocorticographic Signals, Johannes Gruenwald, Sebastian Sieghartsleitner, Christoph Kapeller, Josef Scharinger, Kyousuke Kamada, Peter Brunner, Christoph Guger

2020-Current year OA Pubs

INTRODUCTION: Electrocorticographic (ECoG) high-gamma activity (HGA) is a widely recognized and robust neural correlate of cognition and behavior. However, fundamental signal properties of HGA, such as the high-gamma frequency band or temporal dynamics of HGA, have never been systematically characterized. As a result, HGA estimators are often poorly adjusted, such that they miss valuable physiological information.

METHODS: To address these issues, we conducted a thorough qualitative and quantitative characterization of HGA in ECoG signals. Our study is based on ECoG signals recorded from 18 epilepsy patients while performing motor control, listening, and visual perception tasks. In this study, we first …

Improving Psychological Well-Being Of Young Adults By Conducting Family History Research At A Religious University, Barry M. Lunt, Kelly R. Summers, David A. Wood

Faculty Publications

Prior research suggests that knowledge of one’s family is correlated with, but does not produce, psychological well-being. We test this conjecture, by examining whether participating in family history research (i.e., genealogical research) is associated with psychological well-being above and beyond the effects of knowledge of one’s family, documented in prior research. To test this, we examine whether students enrolled in a university level family history course, improve in family identification, self-esteem, anxiety, resilience, and locus of control more than a control sample. For students enrolled in the family history course, we find an increase in family identification, which in turn …

Transplantation Of Gut Microbiota From Old Mice Into Young Healthy Mice Reduces Lean Mass But Not Bone Mass, Lina Lawenius, Carrie Cowardin, Jeffrey I Gordon, Et Al.

2020-Current year OA Pubs

Aging is associated with low bone and lean mass as well as alterations in the gut microbiota (GM). In this study, we determined whether the reduced bone mass and relative lean mass observed in old mice could be transferred to healthy young mice by GM transplantation (GMT). GM from old (21-month-old) and young adult (5-month-old) donors was used to colonize germ-free (GF) mice in three separate studies involving still growing 5- or 11-week-old recipients and 17-week-old recipients with minimal bone growth. The GM of the recipient mice was similar to that of the donors, demonstrating successful GMT. GM from old …
