BACKGROUND AND HYPOTHESIS: Mounting evidence supports cerebrovascular contributions to schizophrenia spectrum disorder (SSD) but with unknown mechanisms. The blood-brain barrier (BBB) is at the nexus of neural-vascular exchanges, tasked with regulating cerebral homeostasis. BBB abnormalities in SSD, if any, are likely more subtle compared to typical neurological insults and imaging measures that assess large molecule BBB leakage in major neurological events may not be sensitive enough to directly examine BBB abnormalities in SSD.

STUDY DESIGN: We tested the hypothesis that neurovascular water exchange (Kw) measured by non-invasive diffusion-prepared arterial spin label MRI (n = 27 healthy controls [HC], n = …

Hawc Study Of The Very-High-Energy Γ-Ray Spectrum Of Hawc J1844−034, A. Albert, C. Alvarez, D. Avila Rojas, H. A.Ayala Solares, R. Babu, E. Belmont-Moreno, S. Groetsch, D. Huang, P. Huntemeyer, R. Turner, X. Wang, Et Al.

Michigan Tech Publications

Recently, the region surrounding eHWC J1842−035 has been studied extensively by γ-ray observatories due to its extended emission reaching up to a few hundred TeV and potential as a hadronic accelerator. In this work, we use 1910 days of cumulative data from the High Altitude Water Cherenkov (HAWC) observatory to carry out a dedicated systematic source search of the eHWC J1842−035 region. During the search, we found three sources in the region, namely, HAWC J1844−034, HAWC J1843−032, and HAWC J1846−025. We have identified HAWC J1844−034 as the extended source that emits photons with energies up to 175 TeV. We compute …

The Public Health Impact Of Paxlovid Covid-19 Treatment In The United States, Yuan Bai, Zhanwei Du, Lin Wang, Eric H. Y. Lau, Isaac Fung, Petter Holme, Ben Cowling, Alison Galvani, Robert Krug, Lauren Ancel Meyers

Biostatistics, Epidemiology & Environmental Health Sciences: Faculty Publications

The antiviral drug Paxlovid has been shown to rapidly reduce viral load. Coupled with vaccination, timely administration of safe and effective antivirals could provide a path towards managing COVID-19 without restrictive non-pharmaceutical measures. Here, we estimate the population-level impacts of expanding treatment with Paxlovid in the US using a multi-scale mathematical model of SARS-CoV-2 transmission that incorporates the within-host viral load dynamics of the Omicron variant. We find that, under a low transmission scenario (Re∼1.2) treating 20% of symptomatic cases would be life and cost saving, leading to an estimated 0.26 (95% CrI: 0.03, 0.59) million hospitalizations averted, 30.61 (95% …

Covering Properties Via Neutrosophic B-Open Sets, Sudeep Dey, Gautam Chandra Ray

Neutrosophic Systems with Applications

The purpose of this article is to study some covering properties in neutrosophic topological spaces using neutrosophic b-open sets. We define neutrosophic b-open cover, neutrosophic b-compactness, neutrosophic countably b-compactness neutrosophic b-Lindelofness, neutrosophic local b-compactness and study various properties entangled with them. We study some covering properties involving neutrosophic continuous, neutrosophic b-continuous and neutrosophic b*-continuous functions. Lastly, we define neutrosophic base, neutrosophic subbase, neutrosophic second countability via neutrosophic b-open sets and investigate some properties.

Quantum Information Processing Via Dissipation Engineering In Superconducting Circuit Platform, Yunzhao Wang

Arts & Sciences Graduate Student Theses and Dissertations

This thesis discusses the application of dissipative processes in quantum information processing. Conventionally, dissipative processes bring noises into quantum circuits and hinder the ability of computation. Here we explore several ways to engineer and utilize dissipative processes, as a novel approach for quantum information processing. In a single superconducting qutrit, we observe the topological behaviour of the geometric phase under the existence of dephasing. In a manybody superconducting qutrit processor, we design the preparation and stabilization of the AKLT state. By the above examples, we demonstrate the the power of dissipative processes as a novel and promising approach for quantum …

Pain Transformed: The Salutary Effects Of Suffering In Eighteenth-Century France, Anne Seul

Arts & Sciences Graduate Student Theses and Dissertations

At the center of Pain Transformed lies the human body and the experience of suffering, particularly in regard to the unexpectedly beneficial side-effects of pain. I examine depictions of suffering in the literature of eighteenth-century France, a period best understood as one of spirited debate and marked innovation: by way of personal letters, literary and philosophical works, coffee shops, and salons, intellectuals interacted with one another’s ideas in an attempt to redefine society. My focus is on a series of works that merge preoccupations with the body—the physiological processes of how and why people feel, both physically and emotionally—with the …

Assessment Of Forest Stand Characteristics And Environmental Conditions On Soil Burn Severity And Post-Wildfire Flooding In The Hermits Peak/Calf Canyon Fire, Raquel L. Valdez

Civil Engineering ETDs

Wildfire is a natural disturbance in forest ecosystems but has the potential to drastically change watershed conditions, leaving them highly vulnerable to post-wildfire hazards. High severity fires can significantly affect soil and landscape interactions, resulting in decreased evaporation and infiltration and increased runoff in the newly exposed soil surfaces. Most post-wildfire research focuses on reactive solutions. However, the time between wildfires and post-wildfire hazards is growing closer in margin. Therefore, assessing post-wildfire risks, pre-fire is helpful when assessing fire severity and is valuable to resource managers for pre-wildfire management, planning, and mitigation. This research is in the Upper Gallinas Watershed …

Exploring The Capabilities Of Gibbs Sampling In Pulsar Timing Arrays, Nima Laal, William G. Lamb, Joseph D. Romano, Xavier Siemens, Stephen R. Taylor, Rutger Van Haasteren

Physics & Astronomy Faculty Publications

We explore the use of Gibbs sampling in estimating the noise properties of individual pulsars and illustrate its effectiveness using the NANOGrav 11-year dataset. We find that Gibbs sampling noise modeling (GM) is more efficient than the current standard Bayesian techniques (SM) for single pulsar analyses by yielding model parameter posteriors with average effective-sample-size ratio (GM/SM) of 6 across all parameters and pulsars. Furthermore, the output of GM contains posteriors for the Fourier coefficients that can be used to characterize the underlying red noise process of any pulsar’s timing residuals, which are absent in current implementations of SM. Through simulations, …

Wire Deflection Investigation During Wedm Of Aisi 304 Stainless Steel: An Experimental And Numerical Study, Sara A. El-Bahloul, Mohamed G. Elkhateeb

Mansoura Engineering Journal

Wire electrical discharge machining (WEDM) is a specific form of electrical discharge machining that employs a small diameter wire electrode to cut a narrow kerf in the workpiece. Since the wire deflection has a negative effect on the performed cutting, this research seeks to study the resultant wire deflection during WEDM of AISI 304 stainless steel. This study is performed with the help of three types of modeling; namely, mathematical modeling, experimental modeling, and thermo-mechanical finite element modeling. The mathematical modeling is performed to analyze the stresses and the wire lag, while the experimental modeling is achieved to observe the …

Eipeck: Assessing Educators’ Pedagogical Content Knowledge For Engineering Integration In K-12, Pilar Pazos, Francisco Cima Cohuo, Jennifer Kidd, Kristie Gutierrez, Krishnanand Kaipa, Orlando Ayala

Journal of Pre-College Engineering Education Research (J-PEER)

Global efforts are underway to include engineering in pre-college curricula. In the USA, this pursuit led to the inclusion of engineering content in the most recent version of the Next Generation Science Standards that guide K-12 science. As these standards become part of the K-12 curriculum, teachers face the challenge of gaining basic engineering literacy, while developing the associated inclusive pedagogies necessary to integrate engineering content into their classrooms. In this context, teacher preparation programs can benefit from easy-to-implement tools that measure preservice teachers’ readiness to integrate engineering content in their future classrooms. This work describes the development and validation …

Systems Thinking Applied To Higher Education Curricula Development, Reza Rahdar, Mark London, Yuetong Lin, Hong Jiang

Publications

Systems Thinking (ST) is a general and yet nebulous term that describes an approach to understanding and working with complexity in the real world. ST seeks to evaluate different behaviors of individual system elements when they operate in isolation as opposed to when they are integrated as part of a larger system and placed within a particular operating environment. The education environment consists of multiple systems with different digital content, learning goals/outcomes that serve different stakeholders including teachers, learners, and administrators. The inherent complexity and interaction among these various educational system elements and functions make this environment a worthy candidate …

Reaction Steps In Heterogeneous Photocatalytic Oxidation Of Toluene In Gas Phase—A Review, Yerzhigit Tulebekov, Zhandos Orazov, Bagdat Satybaldiyev, Daniel D. Snow, Raphaël Schneider, Bolat Uralbekov

Nebraska Water Center: Faculty Publications

A review of the current literature shows there is no clear consensus regarding the reaction mechanisms of air-borne aromatic compounds such as toluene by photocatalytic oxidation. Potential oxidation reactions over TiO₂ or TiO₂-based catalysts under ultraviolet and visible (UV/VIS) illumination are most commonly considered for removal of these pollutants. Along the pathways from a model pollutant, toluene, to final mineralization products (CO₂ and H₂O), the formation of several intermediates via specific reactions include parallel oxidation reactions and formation of less-reactive intermediates on the TiO₂ surface. The latter may occupy active adsorption sites and …

An Electronic Origin Of Charge Order In Infinite-Layer Nickelates, Hanghui Chen, Yi-Feng Yang, Guang-Ming Zhang, Hongquan Liu

Faculty, Staff and Student Publications

A charge order (CO) with a wavevector [Formula: see text] is observed in infinite-layer nickelates. Here we use first-principles calculations to demonstrate a charge-transfer-driven CO mechanism in infinite-layer nickelates, which leads to a characteristic Ni1+-Ni2+-Ni1+ stripe state. For every three Ni atoms, due to the presence of near-Fermi-level conduction bands, Hubbard interaction on Ni-d orbitals transfers electrons on one Ni atom to conduction bands and leaves electrons on the other two Ni atoms to become more localized. We further derive a low-energy effective model to elucidate that the CO state arises from a delicate competition between Hubbard interaction on Ni-d …

Three Horizons For Future Geoscience, S Iain, Angela C Maria, M Hassina, M Kombada, R Munira, M Raji

More Faculty of Science and Engineering Research

Geoscience, along with other scientific disciplines, is being increasingly challenged on how it can best confront key global challenges, such as climate change, food insecurity, biodiversity loss, human conflict and migration, and persistent poverty. But its traditional association with exploitation of the planet’s natural resources for energy and materials links it with contemporary concerns around unsustainable human practices, arguably fueling a growing disenchantment that is most evident in declining enrollment in university geoscience courses in many countries. Therefore, a fresh re-framing of the geoscience’s relationship to society would seem to be urgently needed. In response to this need, we introduce …

Enhancing The Assessment Of Coercive Control In Spanish Femicide Cases: A Nationally Representative Qualitative Analysis, Rosa Viñas‑Racionero, Chitra Raghavan, Miguel Ángel Soria‑Verde, Mario J. Scalora, Jorge Santos‑Hermoso, José Luís González‑Álvarez, María José Garrido‑Antón

Department of Psychology: Faculty Publications

Purpose Coercive control is a power dynamic central to intimate partner violence (IPV) and consists of tactics to limit one’s partner’s autonomy through constraint, regulation of everyday life, isolation, pursuit, and intimidation and physical force. Such tactics may potentially signal a risk for future lethal or near lethal violence; hence, proper evaluation may enhance the utility of clinical femicide risk assessments. The goal of this study is to explore coercive control behaviors preceding partner femicides in Spain with the intention to provide guidance for its assessment by first responders and law enforcement.

Michigan Tech Publications

The measurement of forest structure has evolved steadily due to advances in technology, methodology, and theory. Such advances have greatly increased our capacity to describe key forest structural elements and resulted in a range of measurement approaches from traditional analog tools such as measurement tapes to highly derived and computationally intensive methods such as advanced remote sensing tools (e.g., lidar, radar). This assortment of measurement approaches results in structural metrics unique to each method, with the caveat that metrics may be biased or constrained by the measurement approach taken. While forest structural diversity (FSD) metrics foster novel research opportunities, understanding …

Comparison Of Conservation Instruments Under Long-Run Yield Uncertainty And Farmer Risk Aversion, Meilin Ma, Carson Reeling, Megan N. Hughes, Shalamar Armstrong, Richard Roth

Department of Agricultural Economics Faculty Publications

Consumers and policymakers are increasingly concerned with environmental sustainability in food production. Yet rates of adoption of many conservation practices vary and are generally low. Existing instruments for practice adoption increase farmers’ expected net benefits from sustainable practices but do not manage associated risks which may be critical to risk-averse farmers. We build a model to characterize practice adoption by risk-averse farmers given practice-driven, long-run yield dynamics under various instruments, including price premiums, lump-sum subsidies and green insurance. We find rich scale and compositional effects that differ across instruments and that green insurance is significantly more cost-effective under plausible conditions.

Development Of Antiviral Peptidomimetics, Songyi Xue

USF Tampa Graduate Theses and Dissertations

Protein-protein interactions (PPIs) are essential for biological processes and are associated with a number of diseases, including cancer, infectious diseases, and neurodegenerative diseases. As a result, modulation of PPIs has been recognized as one of the most promising strategies to develop the novel drugs. Peptide modulators always exhibit higher specificity and affinities with targets than small compounds or monoclonal antibodies, but their broad medicinal effectiveness is constrained by their poor bioavailability and biostability. Peptidomimetics, which have been developed to mimic the structure as well as function of bioactive peptides and proteins, have shown excellent potential in protein surface mimicry and …

Striving Toward Bitcoin Price Stability: Second-Layer Money And The Case For Real Bills, Scrip & Notes, Eduardo Blasco, Carlos García De Enterría

Journal of New Finance

Monetary systems comprise various layers of real and financial assets arranged hierarchically. Due to its properties, Bitcoin is a suitable asset to become the base money of a monetary system once its price has stabilized and people see it more like a medium of exchange than an investment. We review Bitcoin’s characteristics and explain their effect on its intra- and inter-temporal liquidity. We argue that Bitcoin will lower its bid-ask spread once users adopt financial assets convertible to Bitcoin. We propose the use of three financial assets working as Bitcoin derivatives to reduce Bitcoin’s demand shocks and lower its volatility: …

Emotion-Aware Music Recommendation, Hieu Tran, Tuan Le, Anh Do, Tram Vu, Steven Bogaerts, Brian T. Howard

Computer Science Faculty publications

It is common to listen to songs that match one's mood. Thus, an AI music recommendation system that is aware of the user's emotions is likely to provide a superior user experience to one that is unaware. In this paper, we present an emotion-aware music recommendation system. Multiple models are discussed and evaluated for affect identification from a live image of the user. We propose two models: DRViT, which applies dynamic routing to vision transformers, and InvNet50, which uses involution. All considered models are trained and evaluated on the AffectNet dataset. Each model outputs the user's estimated valence and arousal …
