Artificial Intelligence In Head And Neck Cancer: Towards Precision Medicine, Jacob Hagen, Logan Hornung, William Barham, Supratik Mukhopadhyay, Adam Bess, Kevin Contrera, Devraj Basu, Vlad Sandulache, Guillaume Spielmann, Sagar Kansara

Faculty Publications

Over the past 20 years, the capabilities of artificial intelligence (AI) have gained significant interest. While AI has been implemented to various degrees in several disciplines, its unique applications in head and neck cancer (HNC) remain underdeveloped. This narrative review examines the existing body of literature regarding the use of AI in HNC. Studies to date have demonstrated AI’s utility across multiple phases of the HNC treatment continuum. Despite its promise, integrating AI into clinical practice faces several challenges, including concerns about system integrity, generalizability, privacy, and bias. In this review, we address these challenges and offer insights into future …

Density-Valued Solutions For The Boltzmann-Enskog Process, Christian Ennis, Barbara Rüdiger, Padmanabhan Sundar

Faculty Publications

The time evolution of a moderately dense gas evolving in vacuum described by the Boltzmann-Enskog equation is studied. The associated stochastic process, the Boltzmann-Enskog process, was constructed in [1] and further studied in [12, 13]. The process is given by the solution of a McKean-Vlasov equation driven by a Poisson random measure with the compensator depending on the distribution of the solution [1, 12]. The existence of a marginal probability density function at each time for the measure-valued solution is established in this article by using a functional-analytic criterion on Besov spaces [8, 11]. In addition to existence, the density …

Easyspec: An Open-Source Python Package For Long-Slit Spectroscopy, Raniere De Menezes, Francesco Massaro, Michela Negro, Claudia M. Raiteri, Harold Peña-Herazo, Jose A. Acosta-Pulido

Faculty Publications

In modern-day astronomy, near-infrared, optical, and ultraviolet spectroscopy are indispensable for studying a wide range of phenomena, from measuring black hole masses to analyzing chemical abundances in stellar atmospheres. However, spectroscopic data reduction is often performed using instrument-specific pipelines or legacy software well-established and robust within the community that are often challenging to implement and script in modern astrophysical workflows. In this work, we introduce easyspec, a new Python package designed for long-slit spectroscopy, capable of reducing, extracting, and analyzing spectra from a wide range of instruments—provided they deliver raw FITS files, the standard format for most optical telescopes worldwide. …

Sub-Gev Dark Matter And Mev Gamma-Ray Detection With Cosi, Yu Watanabe, Shigeki Matsumoto, Christopher M. Karwin, Tom Melia, Michela Negro, Thomas Siegert, Yuki Watanabe, Hiroki Yoneda, Tadayuki Takahashi

Faculty Publications

Sub-GeV dark matter (DM) has been attracting more attention due to the negative results searching for traditional weakly interacting massive particles (WIMPs). Such particles are expected to produce gamma rays from annihilation in the MeV energy region. Advancements in technology have opened up possibilities to precisely detect MeV gamma rays, leading to the upcoming space-based mission of the Compton Spectrometer and Imager (COSI). We comprehensively and quantitatively study the phenomenology of sub-GeV DM to determine if the COSI observations will probe their viable model parameter regions. We first construct models to describe sub-GeV DM based on the minimality and renormalizability …

Phase-Amplitude Separation Of Wave Function As Local Gauge Transformation, A. R.P. Rau

Faculty Publications

A quantum-mechanical wave function is complex, but all observations are real, expressible through expectation values and transition matrix elements that involve the wave functions. It can be useful to separate at the outset the amplitude and phase as real quantities that together carry the same information that is contained in the complex wave function. Two main avenues for doing so go way back in the history of the subject and have been used both for scattering and bound states. A connection is made here to gauge transformations of electrodynamics where the advent of quantum mechanics and later quantum field theory …

Root Exudates: The Rhizospheric Frontier For Advancing Sustainable Plant Protection, Muhammad Rahil Afzal, Misbah Naz, Youbo Yu, Lisha Yan, Peiyi Wang, Janaki Mohotti, Gefei Hao, Jing-Jiang Zhou, Zhou Chen, Libo Zhang, Qian Wang

Faculty Publications

Root exudates (REs), a diverse array of bioactive metabolites secreted by plant roots in response to environmental stimuli, serve as key mediators of rhizosphere ecology and plant defense responses, offering a promising avenue for sustainable pest management and eco-friendly plant protection. While earlier reviews primarily focus on root exudates in the context of general rhizosphere dynamics and plant-microbial interactions, critical knowledge gaps persist in REs-plant-pest tripartite interactions, the mechanistic basis of REs-mediated plant defense, and their practical integration with integrated pest management (IPM) frameworks. This review provides a synthesis of the latest literature on the biochemical diversity and functions of …

Monitoring Nutrition Security: Perspectives From A Workshop On Nutrition Security Measurement, Ximena Perez-Velazco, Edward A. Frongillo Jr. Ph.D., Joanne F. Guthrie, Alisha Coleman-Jensen, Mariah D. Ehmke, Christian Gregory, Hilary K. Seligman

Faculty Publications

Nutrition security, an emerging concept distinct from and complementary to food security, has gained increasing interest as a focus of efforts to reduce hunger, improve nutrition, and prevent diet-related health conditions. Yet, unlike food security, which has well-established measures, nutrition security lacks standardized measures for assessment. This gap hinders the ability to evaluate progress in improving nutrition security both in the United States and globally. In September 2024, a workshop to explore how to measure nutrition security was hosted by the United States Department of Agriculture Economic Research Service, in collaboration with the Southern University Agricultural Science Center of Excellence …

Navigating Barriers: Examining Social Equality Through Transportation Disadvantages And Perceived Healthcare Accessibility In South Carolina, Yihong Ning, Songyuan Deng, Yuche Chen

Faculty Publications

Transportation inequities significantly contribute to health disparities, particularly in socially and geographically diverse regions like South Carolina. Prior research predominantly relied on objective measurements, like travel time or distance, to assess healthcare accessibility. However, limited attention has been given to the subjective perceptions of transportation barriers. To address this gap, we designed a comprehensive survey consisting of 61 questions (including 32 five-point Likert-scale items) capturing demographic, socioeconomic, and travel behavior data from a diverse sample of South Carolina residents. Urban and rural contexts were distinguished using county categorization and built environment measures. Exploratory Factor Analysis (EFA) was employed to identify …

Categorial Declinations & Democracy, Brenner M. Fissell

Faculty Publications

The most contentious action taken by reform prosecutors has been the issuance of categorical declination policies. Opponents decry this as bureaucratic nullification of democratically enacted offenses, while the prosecutors themselves counter that they are responding to the will of their local electorate. Democracy claims, it appears, have taken center stage in this debate, and they are deployed by both sides. How should we think about democracy and categorical declinations? The most comprehensive scholarly work on this subject is a 2021 article by Professor Kerrel Murray. In this essay, I hope to continue the work begun by Murray, offering additional insights …

Against Activist Cooperation Agreements, Jennifer O'Hare

Faculty Publications

Shareholder activism is at record levels. In a typical campaign, the activist threatens to launch a proxy fight unless the board of directors agrees to take certain actions to increase shareholder value, such as selling off company assets or replacing the CEO. Increasingly, however, there are no proxy fights. Instead, the activist and the board, behind closed doors, quickly agree to settle. The activist withdraws the proxy fight threat, and, in return, the board appoints individuals designated by the activist to sit on the company board. This "Cooperation Agreement" allows the incumbent di- rectors to keep their positions and allows …

Wind Turbine Rotor Design Using High-Fidelity Aerostructural Optimization, Marco Mangano, Sicheng He, Yingqian Liao, Denis-Gabriel Caprace, Andrew Ning, Joaquim R. R. A. Martins

Faculty Publications

Large wind turbines yield more energy but demand careful aeroelastic blade design. Coupled multiphysics design strategies can reduce wind energy costs exploiting fluid-structure interactions. This work presents the first high-fidelity aerostructural optimization study of a large wind turbine rotor.We use blade-resolved fluid dynamics and structural solvers in a monolithic gradient-based optimization framework to explore steady-state torque and blade mass trade-offs. The coupled-adjoint approach computes gradients efficiently, enabling the optimization of over 100 structural and geometric parameters simultaneously. Our optimization study modifies a DTU 10 MW benchmark with a simplified structure and isotropic material properties. The tightly coupled optimizations increase torque …

Effect Of Short-Chain Polymer Binders On The Mechanical And Electrochemical Performance Of Silicon Anodes, Fei Sun, L. Zurita-Garcia, Dean R. Wheeler

Faculty Publications

Polymer binders are crucial components in providing both mechanical support and chemical stability to the structure of porous Li-ion electrodes. Particularly in silicon anodes, the active material undergoes substantial volume expansion of up to 275%. Due to the mechanical constraint of the current collector, these silicon materials tend to expand in the normal direction while exhibiting substantial particle rearrangement and plastic deformation. Conventional rigid binders such as polyacrylic acid (PAA) and polyimide (PI), while providing satisfactory initial capacity, do not eliminate diminished long-term performance. Our research attempts to develop binder formulations that can accommodate sufficient flexibility for the substantial volume …

Exact And Approximate Conformal Inference For Multi-Output Regression, Chancellor Johnstone, Eugene Ndiaye

Faculty Publications

It is common in machine learning to estimate a response y given covariate information x . However, these predictions alone do not quantify any uncertainty associated with said predictions. One way to overcome this deficiency is with conformal inference methods, which construct a set containing the unobserved response with a prescribed probability. Unfortunately, even with a one-dimensional response, conformal inference is computationally expensive despite recent encouraging advances. In this paper, we explore multi-output regression, delivering exact derivations of conformal inference p-values when the predictive model can be described as a linear function of y . Additionally, we introduce a multivariate …

I Do, And I Will: Effectual Religiosity May Strengthen The Triad Chord Of Commitment For Women Of Faith, Tamara M. Chamberlain, Loren Marks, David C. Dollahite, Ashley Lebaron-Black, Elizabeth Kay Madsen, Christina N. Cooper

Faculty Publications

Although religiosity is commonly linked to marital satisfaction in sociological research, few studies have examined how it strengthens marital commitment among women of faith. This study explored the perspectives of religious, heterosexual married women using interviews in the United States from 196 highly religious couples with successful marriages. Three core themes emerged: (1) personal commitment—including the decision to marry, religious beliefs and practices, and the need for effort and sacrifice; (2) moral commitment—highlighting sexual relations before marriage, promises made before God, family, and friends, and views on fidelity and divorce; and (3) structural commitment— emphasizing the role of a religious …

Development Of Respiratory Sinus Arrhythmia In Young Infants With Autism Spectrum Disorder, Preterm Birth, And Typical Development, Jessica Bradshaw, John E. Richards, Julia Yurkovic-Harding, Eilis Mclaughlin

Faculty Publications

Respiratory sinus arrhythmia (RSA) is a key index of parasympathetic function and environmental adaptability. Lower resting RSA has been linked to preterm (PT) birth in infancy and autism spectrum disorder (ASD) in childhood, yet RSA across the first 2 years in young infants born PT or later diagnosed with ASD remains unknown. This study examined resting RSA and mean interbeat interval (IBI) development from 1 to 24 months in infants at varying ASD likelihoods, including infant siblings of children with ASD and those born PT. A longitudinal design tracked resting RSA and mean IBI in 137 infants from 1 to …

Subarctic cities notoriously experience severe winter pollution episodes with fine particle (PM2.5) concentrations above 35 µg m−3, the US Environmental Protection Agency (EPA) 24 h standard. While winter sources of primary particles in Fairbanks, Alaska, have been studied, the chemistry driving secondary particle formation is elusive. Biomass burning is a major source of wintertime primary particles, making the PM2.5 rich in light-absorbing brown carbon (BrC). When BrC absorbs sunlight, it produces photooxidants – reactive species potentially important for secondary sulfate and secondary organic aerosol formation – yet photooxidant measurements in high-latitude PM2.5 remain scarce. During the winter of 2022 Alaskan …

When the Bartons married, Edna already had a five-year-old daughter, Helen, from a previous marriage. Ruth was the first of two children born to Edna’s second marriage. The family was living in Mount Pleasant, Utah, but returned to the home of Edna’s father, Edward Cottrell, for the birth of the baby. She was named Ruth for the biblical heroine, and Josephine because she shared a birthday with the prophet Joseph Smith. A younger sister, Laura Jean, joined the family in …

Computational Detection Of Articulation Transients In Clarinet Performance, Whitney L. Coyle, Max Griffin, Makayle S. Kellison

Faculty Publications

Accurate measurement of note-to-note transitions is essential for analyzing articulation in clarinet performance. Traditional methods rely on either subjective amplitude thresholds—such as the time between 5% and 95% RMS levels—or direct measurement of tongue-reed contact time using reed-mounted sensors. These approaches are limited by their dependence on user-defined parameters or invasive hardware. This study proposes a computational alternative: ΔT, a curvature-based metric defined as the time interval between surrounding minima in the second derivative of the mouthpiece pressure envelope. Using data from a sensor-equipped mouthpiece (SEM), we compare ΔT to both threshold-based timing (T_t) …
