Galaxy morphology in atomic hydrogen (H I) and in the ultraviolet (UV) are closely linked. This has motivated their combined use to quantify morphology over the full H I disc for both H I and UV imaging. We apply galaxy morphometrics: concentration, asymmetry, gini, M₂₀ and multimode-intensity-deviation statistics to the first moment-0 maps of the WALLABY Survey of galaxies in the hydra cluster centre. Taking advantage of this new H I survey, we apply the same morphometrics over the full H I extent on archival GALEX FUV and NUV data to explore how well H I truncated, extended ultraviolet …

Turning Dead Leaves Into An Active Multifunctional Material As Evaporator, Photocatalyst, And Bioplastic, Siyuan Fang, Xingyi Lyu, Tian Tong, Aniqa Ibnat Lim, Tao Li, Jiming Bao, Yun Hang Hu

Michigan Tech Publications, Part 1

Large numbers of leaves fall on the earth each autumn. The current treatments of dead leaves mainly involve completely destroying the biocomponents, which causes considerable energy consumption and environmental issues. It remains a challenge to convert waste leaves into useful materials without breaking down their biocomponents. Here, we turn red maple dead leaves into an active three-component multifunctional material by exploiting the role of whewellite biomineral for binding lignin and cellulose. Owing to its intense optical absorption spanning the full solar spectrum and the heterogeneous architecture for effective charge separation, films of this material show high performance in solar water …

Searching For Tev Dark Matter In Irregular Dwarf Galaxies With Hawc Observatory, R. Alfaro, C. Alvarez, J. C. Arteaga-Velázquez, D. Avila Rojas, H. A.Ayala Solares, R. Babu, D. Huang, R. Turner, Et Al.

Michigan Tech Publications, Part 1

We present the results of dark matter (DM) searches in a sample of 31 dwarf irregular (dIrr) galaxies within the field of view of the HAWC Observatory. dIrr galaxies are DM-dominated objects in which astrophysical gamma-ray emission is estimated to be negligible with respect to the secondary gamma-ray flux expected by annihilation or decay of weakly interacting massive particles (WIMPs). While we do not see any statistically significant DM signal in dIrr galaxies, we present the exclusion limits (95% C.L.) for annihilation cross section and decay lifetime for WIMP candidates with masses between 1 and 100 TeV. Exclusion limits from …

Autonomous Single-Molecule Manipulation Based On Reinforcement Learning, Bernhard Ramsauer, Grant J. Simpson, Johannes J. Cartus, Andreas Jeindl, Victor García-López, James M. Tour, Leonhard Grill, Oliver T. Hofmann

Faculty Publications

Building nanostructures one-by-one requires precise control of single molecules over many manipulation steps. The ideal scenario for machine learning algorithms is complex, repetitive, and time-consuming. Here, we show a reinforcement learning algorithm that learns how to control a single dipolar molecule in the electric field of a scanning tunneling microscope. Using about 2250 iterations to train, the algorithm learned to manipulate the molecule toward specific positions on the surface. Simultaneously, it generates physical insights into the movement as well as orientation of the molecule, based on the position where the electric field is applied relative to the molecule. This reveals …

Attochemistry Regulation Of Charge Migration, Aderonke S. Folorunso, François Mauger, Kyle A. Hamer, Denawakage D. Jayasinghe, Imam S. Wahyutama, Justin R. Ragains, Robert R. Jones, Louis F. Dimauro, Mette B. Gaarde, Kenneth J. Schafer, Kenneth Lopata

Faculty Publications

Charge migration (CM) is a coherent attosecond process that involves the movement of localized holes across a molecule. To determine the relationship between a molecule's structure and the CM dynamics it exhibits, we perform systematic studies of para-functionalized bromobenzene molecules (X-C6H4-R) using real-time time-dependent density functional theory. We initiate valence-electron dynamics by emulating rapid strong-field ionization leading to a localized hole on the bromine atom. The resulting CM, which takes on the order of 1 fs, occurs via an X localized → C6H4delocalized → R localized mechanism. Interestingly, the hole contrast on the acceptor functional group increases with increasing electron-donating …

The Fourth Industrial Revolution And Legal Education, Steven R. Smith

Georgia State University Law Review

A “Fourth Industrial Revolution” (4IR) will dramatically change current law students’ careers. Innovations in technology, business, and social structures will require different and more sophisticated legal services. Law school graduates will be responsible for harnessing, encouraging, and establishing legal controls that offer society the benefits of these new technologies while limiting the undesirable side effects. At the same time, the recurring, repetitive practice of law will begin to disappear as more work is done much cheaper and better by machines.

The 4IR presents extraordinary opportunities for law schools, the legal profession, and graduates, but it also presents significant challenges. To …

When Does A Non-Fungible Token (Nft) Become A Security?, Brian Elzweig, Lawrence J. Trautman

Georgia State University Law Review

Non-fungible tokens (NFTs) gained prominence in the news cycle during March 2021 when $69 million was paid in a cryptocurrency known as Ether for a unique digital art piece titled Everydays: The First 5000 Days. Regulating NFTs is complicated because the technology encompasses varied applications. Therefore, it is the particular use of a given NFT that will determine its appropriate regulatory regime. For example, NFTs may take the form of collectibles, data associated with a physical item, financial instruments, or permanent records associated with a person, such as marriage licenses or property deeds. Just like digital art in the form …

A Square Double Helix In A Round Hole: Forensic Genetic Genealogy Searches And The Fourth Amendment, Matthew Sweat

Georgia State University Law Review

A forensic genetic genealogy search (FGGS) involves law enforcement’s use of consumer DNA databases to generate leads to solve cold cases. As a result of more modern technological processes, the DNA profiles kept in consumer databases are far more revealing than the DNA profiles stored in the FBI’s Combined DNA Index System (CODIS). Accordingly, each DNA profile in a consumer database can be used to identify hundreds of relatives related to the DNA’s contributor.

The government’s use of consumer DNA databases to locate the perpetrators of horrific, unsolved crimes has generated fans and critics. Supporters of FGGSs argue that, in …

First, Do No Harm: Prioritizing Patients Over Politics In The Battle Over Gender-Affirming Care, Greg Mercer

Georgia State University Law Review

The medical community’s move to reclassify gender dysphoria as a condition that results in distress rather than a mental disorder has been instrumental in destigmatizing transgender people. However, state laws that aim to strip physicians of their ability to prescribe gender-affirming care, along with physicians’ refusal to comply with federal regulations requiring access to gender-affirming care, threaten to undo those gains. Opponents of gender-affirming care attempt to wield the concept of medical judgment as both a sword and a shield—preventing physicians from exercising their medical judgment to provide gender-affirming care while simultaneously allowing physicians to abstain from providing it. Although …

Zero Torque Compliant Mechanisms Employing Pre-Buckled Beams, Pietro Bilancia, Samuel Porter Smith, Giovanni Berselli, Spencer P. Magleby, Larry L. Howell

Faculty Publications

The concept of a statically balanced mechanism with a single rotational degree of freedom is presented. The proposed device achieves static balancing by combining positive stiff- ness elements and negative stiffness elements within a nuclear domain. Two designs are discussed. The first is composed of an Archimedean spiral and two pinned-pinned pre-buckled beams. The overall mechanism is modeled via an analytical approach and the element dimensions are optimized. The optimal configuration is then tested through finite element analysis (FEA). A second approach replaces the spiral beam with elastic custom-shaped spline beams. An FEA optimization is performed to determine the shape …

Conceptualizing Stable States In Origami-Based Devices Using An Energy Visualization Approach, Jacob Greenwood, Larry L. Howell, Alex Avila, Spencer P. Magleby

Faculty Publications

In many origami-based applications, a device needs to be maintained in one or more fold states. The origami stability integration method (OSIM) presented in this paper pro- vides an approach for graphically combining various techniques to achieve stability. Existing stability techniques are also categorized into four groups based on whether they are intrinsic or extrinsic to the origami pattern and whether they exhibit gradual or non-gradual energy storage behaviors. These categorizations can help designers select appropriate techniques for their applications. The paper also contains de- sign considerations and resources for achieving stability. Finally, two case studies are presented that use …

Fluid Management In Septic Patients With Pulmonary Hypertension, Review Of The Literature, Blerina Asllanaj, Elizabeth Benge, Jieun Bae, Yi Mcwhorter

School of Medicine Faculty Research

The management of sepsis in patients with pulmonary hypertension (PH) is challenging due to significant conflicting goals of management and complex hemodynamics. As PH progresses, the ability of right heart to perfuse lungs at a normal central venous pressure (CVP) is impaired. Elevated pulmonary vascular pressure, due to pulmonary vasoconstriction and vascular remodeling, opposes blood flow through lungs thus limiting the ability of right ventricle (RV) to increase cardiac output (CO) and maintain adequate oxygen delivery to tissue. In sepsis without PH, avoidance of volume depletion with intravascular volume replacement, followed by vasopressor therapy if hypoperfusion persists, remains the cornerstone …

Social Transmission Of Predator Information Through Referential Alarm Calls Within And Across Species, Carly Trebac

Honors Program: Senior Projects (Public)

Animals can encode information about a predator’s size, identity, or threat through alarm calls. This can provide referential information that can be used by individuals within and across species receiving the information. Referential alarm calls can encode information through changes in structure or rate of the call, and these variances in their call can elicit different responses, such as fleeing or mobbing, in conspecifics and heterospecifics. We aimed to investigate whether white-breasted nuthatch alarm calls can encode referential information and elicit different responses from conspecifics. Previous studies showed that a related species of nuthatch varies their call rate in the …

Pharmacotherapeutic Challenges For Treating The Baby Boomer Cohort, Scott P. Pelok

Faculty Scholarship

As the baby boomer cohort ages, they have an ever‐increasing number of comorbidities and associated poly‐pharmaceutical treatment needs. The challenge for healthcare providers is to stay current of advancements in providing for this aging population. Baby boomers can expect a longer life expectancy than any previous generation. Yet, longevity has not correlated with better health. This cohort is noted for being goal driven and more self‐assured than younger generations. They are resourceful and will often attempt to fix things themselves, including their healthcare. They believe hard work deserves justifiable rewards and relaxation. These beliefs have resulted in baby boomers utilizing …

Text And Data Mining Applications For Teaching Music Bibliography, Taylor Greene, Laurie Sampsel

Library Presentations, Posters, and Audiovisual Materials

Text and data mining (TDM) is a process of increasing interdisciplinary potential and one with many practical applications for music graduate students. TDM, however, remains a topic rarely introduced in the music bibliography course. Understandably, talk of artificial intelligence, algorithms, and programming languages are intimidating to music students, but thanks to software applications, knowledge about these computer science topics are not required to participate in research using TDM. This presentation explores ways to introduce digital humanities to music students through TDM.

In our presentation, we will discuss two approaches to incorporating TDM into the music bibliography course, focusing on two …

Benthic Habitat Mapping Of Mountain Top Bank Within The Northern Gulf Of Mexico Through Integrated Geophysical And Visual Data Analysis, Bethany Pertain

Master's Theses

Mesophotic coral ecosystems (MCEs) are among the seafloor ecosystems that have been poorly studied throughout the world’s oceans, but they are a vital and diverse ecosystem that should be prioritized for future mapping and ecological studies. Priority should be given to them because they possess natural, social, and economic values, and face a variety of threats, all of which, if not better understood will result in the loss of this unique ecosystem. Insights into these ecosystems, among other deep-sea environments, are lacking due to difficulty accessing them, inherent lag between data collection by an autonomous system and observation by a …

Memory Retrieval, Reconsolidation, And Extinction: Exploring The Boundary Conditions Of Post-Conditioning Cue Exposure, Nicole C. Ferrara, Janine L. Kwapis, Sydney Trask

Purdue University Libraries Open Access Publishing Fund

Following fear conditioning, behavior can be reduced by giving many CS-alone presentations in a process known as extinction or by presenting a few CS-alone presentations and interfering with subsequent memory reconsolidation. While the two share procedural similarities, both the behavioral outcomes and the neurobiological underpinnings are distinct. Here we review the neural and behavioral mechanisms that produce these separate behavioral reductions, as well as some factors that determine whether or not a retrieval-dependent reconsolidation process or an extinction process will be in effect.

Applied Machine Learning In Development Of Geospatial Information Tools For Sustainable Groundwater Management, Saul Gallegos Ramirez

Theses and Dissertations

Groundwater plays an important role in sustainable water resource management. Globally, the development of groundwater resources for irrigation provides a stable water source and enhances food security. However, developing groundwater resources is difficult, requiring the collection, synthesis, analysis, and dissemination of information about groundwater in an accessible, effective manner so decision makers have the knowledge and tools to implement sustainable management strategies. In this dissertation, I present solutions to assist with the paucity of groundwater data. The first problem I explore is extending the Palmer Drought Severity Index to near present day. This dataset is crucial to current groundwater imputation …

Ecological Boundaries And Constraints On Viable Eco-Evolutionary Pathways, Kyle E. Coblentz, John P. Delong

School of Biological Sciences: Faculty Publications

Evolutionary dynamics are subject to constraints ranging from limitations on what is physically possible to limitations on the pathways that evolution can take. One set of evolutionary constraints, known as ‘demographic constraints’, constrain what can occur evolutionarily due to the demographic or dynamical consequences of evolution leading to conditions that make populations susceptible to extinction. These demographic constraints can limit the strength of selection or the rates of environmental change populations can experience while remaining extant and the trait values a population can express. Here we further hypothesize that the population demographic and dynamic consequences of evolution also can constrain …

Patterns Of Care Partner Communication For Persons Living With Dementia In The Emergency Department, Adrian D. Haimovich, Aidan Gilson, Evangeline Gao, Ling Chi, Cameron J. Gettel, Mara Schonberg, Ula Hwang, Richard A. Taylor
