Background

Optimizing human performance under stressful physical and cognitive conditions is paramount during high-stakes military operations. As such, interventions to improve warfighter performance by mitigating task-induced cognitive performance deficits are necessary. While caffeine is the most widely consumed psychoactive substance in the world, common side effects (i.e. anxiousness, micro-saccades, irritability) may be detrimental to warfighter operations. Theacrine, a purine alkaloid similar in structure to caffeine but with a longer half-life, less habituation, and fewer side effects, is proposed as a caffeine-alternative to enhance cognitive resilience.

Effects Of Elicitation Method On Functionally Relevant Item Selection In Spanish And English Monolinguals And Bilinguals, Dallin J. Bailey, Esther Barahona Wilkes

Faculty Publications

Purpose: One important decision speech language pathologists make when planning anomia treatment is the identification and selection of the specific vocabulary items to target during therapy. However, this process is not entirely straightforward. Although ‘functional relevance’ has high face validity for the identification of target items, interpretations differ, which may impact which words are selected for therapy. As such, target item selection methods vary, with resulting items impacted by the specific method used. There are also many person-level variables that may impact the functional relevance of specific items, such as the heritage language of the patient or their bilingualism status. …

Predicting Sleep And Sleep Stage In Children Using Actigraphy And Heartrate Via A Long Short-Term Memory Deep Learning Algorithm: A Performance Evaluation, Robert Weaver Med, Phd, James White, Olivia Finnegan, Hongpeng Yang, Zifei Zhong, Keagan Kiely, Catherine Jones, Yan Tong, Srihari Nelakuditi, Rahul Ghosal, David E.

Children's ambulatory sleep is commonly measured via actigraphy. However, traditional actigraphy measured sleep (e.g., Sadeh algorithm) struggles to predict wake (i.e., specificity, values typically < 70) and cannot predict sleep stages. Long short-term memory (LSTM) is a machine learning algorithm that may address these deficiencies. This study evaluated the agreement of LSTM sleep estimates from actigraphy and heartrate (HR) data with polysomnography (PSG). Children (N = 238, 5–12 years,52.8% male, 50% Black 31.9% White) participated in an overnight laboratory polysomnography. Participants were referred be-cause of suspected sleep disruptions. Children wore an ActiGraph GT9X accelerometer and two of three consumer wearables(i.e., Apple Watch Series 7, Fitbit Sense, Garmin Vivoactive 4) on their non-dominant wrist during the polysomnogram. LSTM estimated sleep versus wake and sleep stage (wake, not-REM, REM) using raw actigraphy and HR data for each 30-s epoch. Logistic regression and random forest were also estimated as a benchmark for performance with which to compare the LSTM results. A 10-fold cross-validation technique was employed, and confusion matrices were constructed. Sensitivity and specificity were calculated to assess the agreement between research-grade and consumer wearables with the criterion polysomnography. For sleep versus wake classification, LSTM outperformed logistic regression and random forest with accuracy ranging from 94.1to 95.1, sensitivity ranging from 94.9 to 95.9 across different devices, and specificity ranging from 84.5 to 89.6. The addition of HR improved the prediction of sleep stages but not binary sleep versus wake. LSTM is promising for predicting sleep and sleep staging from actigraphy data, and HR may improve sleep stage prediction.

Creatine Monohydrate Supplementation For Older Adults And Clinical Populations, Darren G. Candow, Sergej M. Ostojic, Philip D. Chilibeck, Igor Longobardi, Bruno Gualano, Mark A. Tarnopolsky, Theo Wallimann, Terence Moriarty, Richard B. Kreider, Scott C. Forbes, Uwe Schlattner, Jose Antonio

Background: The biological process of aging is typically associated with a decrease in muscle quantity, muscle performance (primarily strength), bone mass and architecture, functionality and neurological/cognitive function. From a healthy aging perspective, interventions that have the potential to overcome or attenuate these decrements are clinically relevant.

Methods: We conducted a narrative review on the efficacy of creatine monohydrate supplementation (CrM) in older adults. Results: Accumulating research shows that CrM, primarily when combined with exercise training, is safe and has beneficial effects on measures of whole-body lean body mass, regional muscle size, muscle strength, bone area and thickness, functional ability, glucose …

Mesopelagic zone (MZ) carbon budgets comparing supply with demand can be difficult to constrain due to the temporal and spatial offsets between key sources and sinks, their associated uncertainties, and potential sampling biases. To address these challenges, the EXport Processes in the Ocean from RemoTe Sensing (EXPORTS) campaign increased the number and variety of simultaneous measurements to monitor temporal variability in the MZ carbon budget using both a Lagrangian frame of reference and long-term autonomous observations. In this study, we collate a comprehensive combination of new and previously published organic carbon supply and demand measurements collected from the surface (5 …

Electroexcitation Of Nucleon Resonances And Emergence Of Hadron Mass, Patrick Achenbach, Daniel S. Carman, Ralf Gothe, Kyungseon Joo, Victor I. Mokeev, Craig D. Roberts

Faculty Publications

Developing an understanding of phenomena driven by the emergence of hadron mass (EHM) is one of the most challenging problems in the Standard Model. This discussion focuses on the impact of results on nucleon resonance (N*) electroexcitation amplitudes (or γ_vpN*) obtained from experiments during the 6 GeV era in Hall B at Jefferson Lab on understanding EHM. Analyzed using continuum Schwinger function methods (CSMs), these results have revealed new pathways for the elucidation of EHM. A good description of the Δ (1232) 3/2⁺, N (1440) 1/2⁺, and Δ (1600) 3/2^{+ …}

Let’S Teach More Accurate And Inclusive History! The Case Of Islamic Contributions To Mathematics And Science, Noah (Nuh) Aydin

Faculty Publications

Schools commonly teach a history of mathematics and science that is Eurocentric. This selective version of the history of science, called Classical Narrative by some, is rooted in colonial times and mindset, and has reinforced certain negative opinions about other cultures. It ignores or downplays contributions to mathematics and sciences from non-western civilizations, and falsely attributes many scientific discoveries to European scholars. Medieval Islamic Civilization, which had strong connections to Renaissance Europe, serves as a clear example of how this narrative is distorted. Based on research on primary sources since the middle of the 20th century, we now know that …

Water Exposure Time Distributions Controlled By Freshwater Releases In A Semi-Enclosed Estuary, Caitlin R.R. Turner, Matthew Hiatt

Faculty Publications

Freshwater diversions manage water shortages, salinity, and control floodwater by redirecting river flows; however, their full ecological and hydrological impact remains unknown. This study examines the Lake Pontchartrain Estuary in Louisiana using a hydrodynamic model and Lagrangian particle tracking to assess how diversion operations (open, closed) and tributary discharge levels (low, median, high) influence water exposure time—the cumulative duration water remains in a domain, including re-entry. Exposure time was analyzed based on the time required for 50%, 75%, and 90% of released particles ((Formula presented.), (Formula presented.), and (Formula presented.)) to leave a defined region of interest (ROI). Results show …

Whose Right(S)?: Civil Rights Impact Of Cultural Conflicts In The Curriculum, S. David Mitchell

Faculty Publications

Statutes seeking to prohibit the teaching of certain curricular topics that are considered divisive infringe upon the civil rights of students, parents, and teachers. The conflict over what should be taught implicates the rights of students, specifically their right to receive and to learn information; the rights of parents, specifically the right to control the education of their children; and the rights of teachers, specifically the First Amendment and academic freedom. “Anti-Woke” legislation, as it is broadly termed, is designed to silence those who seek to engage in the critical analysis of the structural and systemic barriers that have prevented …

From Disruption To Integration: Cryptocurrency Prices, Financial Fluctuations, And Macroeconomy, Zhengyang Chen

Faculty Publications

This paper examines cryptocurrency shock transmission to financial markets and the macroeconomy using a Bayesian structural VAR with Pandemic Priors from 2015 to 2024. By affecting overall risk appetite, cryptocurrency price shocks generate positive financial market spillovers, accounting for 18% of equity and 27% of commodity price fluctuations. Real economic effects are significant in driving investment but remain limited, contributing only 4% to unemployment and 6% to industrial production variance. However, cryptocurrency shocks explain 18% of price-level forecast error variance at long horizons. Narrative analysis reveals sentiment and technology as primary shock drivers. These findings demonstrate cryptocurrency's deep financial system …

Identification Of Authentic Gnss Signals In Time-Differenced Carrier-Phase Measurements With A Software-Defined Radio Receiver, Zhen Zhu, Sanjeev Gunawardena, Eric Vinande, Jason Pontious

Faculty Publications

The time-differenced carrier phase can be computed from measurements recorded by a multi-global navigation satellite system software-defined radio receiver such as PyChips, from which the user displacement and receiver clock drift can be solved. PyChips is able to simultaneously track authentic and inauthentic signals in separate channels, which makes it possible to observe both types of measurements with corresponding navigation data. A random sample consensus algorithm has been introduced to assess the consistency between the measurements and data. This algorithm successfully separated authentic channels from inauthentic channels when they are broadcast simultaneously.

Sex-Dependent Modulation Of Behavioral Allocation Via Ventral Tegmental Area-Nucleus Accumbens Shell Circuitry, Kristen A. Mclaurin, Jessica M. Illenberger, Hailong Li, Rosemarie M. Booze, Charles F. Mactutus

Faculty Publications

Diagnostic criteria for substance use disorder, cocaine type (i.e., cocaine use disorder), outlined in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders, imply that the disorder arises, at least in part, from the maladaptive allocation of behavior to drug use. To date, however, the neural circuits involved in the allocation of behavior have not been systematically evaluated. Herein, a chemogenetics approach (i.e., designer receptors exclusively activated by designer drugs (DREADDs)) was utilized in combination with a concurrent choice self-administration experimental paradigm to evaluate the role of the mesolimbic neurocircuit in the allocation of behavior. Pharmacological activation …

Feedback Parameters For A Closed-Loop Multiple-Input Multiple-Output Model Of The Upper Limb, Ian Syndergaard, Daniel B. Free, Dario Farina, Steven Knight Charles

Faculty Publications

Both closed-loop models and multi-input multi-output (MIMO) models of the neuromusculoskeletal system of the upper limb are important for simulating and understanding motor control. Yet no large-scale linear neuromusculoskeletal models of the upper limb that are both closed-loop and MIMO have been developed. The primary difficulty in creating such models is choosing appropriate feedback parameters (such as feedback gains and delays), as such a collection of parameters is not available in the literature. The purpose of this work is to 1) present a method for developing MIMO models of short-loop afferent feedback and 2) offer estimates of average feedback parameter …

Understanding The Effect Of Chiral Nn Parametrization On Nuclear Shapes From An Ab Initio Perspective, Kevin S. Becker, Kristina D. Launey, Andreas Ekström, Grigor H. Sargsyan, Darin C. Mumma, Tomáš Dytrych, Daniel Langr, Jerry P. Draayer

Faculty Publications

The ab initio symmetry-adapted no-core shell model naturally describes nuclear deformation and collectivity, and is therefore well-suited to studying the dynamics and coexistence of shapes in atomic nuclei. For the first time, we analyze how these features in low-lying states of⁶Li and¹²C are impacted by the underlying realistic nucleon-nucleon interaction. We find that the interaction parametrization has a notable but limited effect on collective shapes in the lowest⁶Li and¹²C states, while collective structures in the excited 2⁺ state of¹²C are significantly more sensitive to the interaction parameters and exhibits …

Exploring The Translation Lookaside Buffer (Tlb) For Low-Level Task Differentiation And Classification, Cristian Agredo, Daniel F. Koranek, Christine M. Schubert, Jose A. Gutierrez Del Arroyo, Tor J. Langehaug, Scott R. Graham

Faculty Publications

The primary focus of modern Central Processing Unit (CPU) technologies is performance improvement, with security often considered a secondary concern. As a result, vulnerabilities within the system are overlooked. While significant research, both offensive and defensive, has been conducted on CPU caches, relatively little attention has been given to the Translation Lookaside Buffer (TLB) due to its perceived lack of data granularity. Prior studies have typically combined multiple Hardware Performance Counters (HPCs) or relied on timing analysis to extract meaningful insights. In contrast, this study introduces a novel methodology that leverages only TLB related HPCs for multi-task classification, without incorporating …

Uncovering Multiscale Structure-Property Correlations Via Active Learning In Scanning Tunneling Microscopy, Ganesh Narasimha, Deja Kong, Paras Regmi, Rongying Jin, Zheng Gai, Rama Vasudevan, Maxim Ziatdinov

Faculty Publications

Atomic arrangements and local sub-structures fundamentally influence emergent material functionalities. These structures are conventionally probed using spatially resolved studies and the property correlations are deciphered by a researcher based on sequential explorations, thereby limiting the efficiency and scope. Here we demonstrate a multi-scale Bayesian deep-learning based framework that automatically correlates material structure with its electronic properties using scanning tunneling microscopy (STM) measurements in real-time. Its predictions are used to autonomously direct exploration toward regions of the sample that optimize a given material property. This method is deployed on a low-temperature ultra-high vacuum STM to understand the structure-property relationship in a …

Lesion-symptom mapping techniques are essential to determine brain regions critical for language functions. However, high collinearity in neuroimaging and behavioural data remains a challenge for distinguishing neural substrates supporting multiple language domains (shared variance) and those subserving specific language functions (unique variance). Here, we employed a novel approach to multimodal lesion-symptom mapping using multivariate partial least squares regression to delineate the latent structure of lesion-behavioural mapping in aphasia and decompose the shared and unique neural determinants of language impairments. A total of 86 participants with chronic (>12-month post-stroke) aphasia after left hemisphere strokes were examined. Language impairment was assessed …

An International Perspective On Geography Curricula: Paving A Way Forward For Geographical Thinking, Tomáš Bendl, Hilde Storrøsæter, Lene Møller Madsen, David Trokšiar, Raphaële De La Martinière, Shanshan Liu, Sizakele Serame, Jerry T. Mitchell, Péter Bagoly-Simó, Yushan Duan, Gillian Kidman

Faculty Publications

Geographical thinking is a cornerstone of modern geography education. Despite its universal value, no large-scale international study has systematically examined its integration into diverse curricular documents. This study investigates how geographical thinking is embedded in the curricula of nine countries, focusing on content and procedural dimensions. Using a structured analytical framework, the research reveals significant patterns and gaps, particularly the underrepresentation of place as a central concept, the lack of explicit focus on geographical thinking, and the limited emphasis on its procedural dimension. The findings emphasise the need for stronger interconnections between these dimensions to promote a more comprehensive approach …

Investigation Of Stability And Control Shortcomings Of The North American X-15, William Lorenzo, Ramana Grandhi, Timothy T. Takahashi

Faculty Publications

There is growing interest in the design of maneuvering high-speed aircraft to fly within or at the edge of the atmosphere. We identify and develop novel quasi-static vehicle screening methodologies, suitable for use during preliminary design, to better predict an incipient loss of control due to the dynamic effects of feedback. We validate these metrics by reverse-engineering Neil Armstrong’s 1962 loss of control and inadvertent atmospheric skip while piloting the X-15. In 1962, then-extant flight dynamics screening methods did not forecast likely troubles. We assemble and refine a collection of predictive metrics which operate upon basic quasi-static aerodynamic data and …

Climatologist Mann's Defamation Suit Victory: Can It Resolve The Crisis Of Expertise, David S. Caudill

Faculty Publications

When a jury awarded one million dollars in punitive damages to climatologist Michael Mann, in his defamation suit against writer Mark Steyn (who accused Mann of scientific fraud), it was newsworthy, even surprising, because opinions regarding scientific matters are rarely actionable. And yet it was not seen as a groundbreaking event in terms of legal doctrine, since the outcome was easily justifiable— Steyn’s accusation was provably false. However, even if the Constitutional contours of defamation law did not change, the Mann verdict has far-reaching implications for a major contemporary social phenomenon, namely the so-called crisis of expertise, a term identifying …

Stomach Content And Stable Isotope Analysis Of Invasive Lionfish (Pterois Volitans) In The Florida Keys, Emily E. Shallow, Cassandra N. Glaspie, Michael J. Polito, Mitchell S. Lovell

Faculty Publications

The invasive red lionfish, Pterois volitans, plays a unique role in seagrass and reef ecosystems, where it functions as a top predator and competitor for both food and shelter. Given the ubiquitous distribution of lionfish in the Gulf of Mexico and Caribbean basins, their species provides an excellent opportunity to understand how an invasive predator's diet and primary energy pathways change as a function of size and habitat type. To investigate these patterns, we studied lionfish from a mosaic of deep reef, shallow patch reef, and seagrass bed habitats in the Florida Keys using stomach contents and stable isotope analysis …
