Several recent studies have evaluated technologies of spent nuclear fuel processing specifically for solidifying transuranic (TRU) waste as a by-product of fission. Of the TRU group, plutonium and the minor actinides will be responsible for the bulk of the radiotoxicity and heat generation of spent nuclear fuel in the long term (300 to 20,000 years). In this study, we investigated magnesium potassium phosphate (MKP)-based compounds as host waste forms for the encapsulation of inactive trivalent Nd and Sm as analogues of the minor trivalent actinides, Am and Cm. Waste forms were fabricated under ambient atmospheric conditions by adding 5 wt.% …
Strategic (Non)Disclosure: Activation And Avoidance Of Social Ties Among Women Seeking Abortion, Kathleen Broussard
Strategic (Non)Disclosure: Activation And Avoidance Of Social Ties Among Women Seeking Abortion, Kathleen Broussard
Faculty Publications
The increased politicization of sexual and reproductive health has created barriers to medically necessary care. In absence of formal health care, social ties become critical sources of information and resources, yet the disclosure of stigmatized health needs carries significant risk. How do people navigate the risks and benefits of disclosure when seeking care for stigmatized needs? Drawing on original survey data (N = 153) and in-depth interviews (N = 55) with women who attempted a self-managed abortion, I first describe the distinct roles of weak and strong ties in women’s health-seeking experiences. I then demonstrate how both partial disclosure and …

Introducing The Second-Order Features Adjoint Sensitivity Analysis Methodology For Neural Ordinary Differential Equations—I: Mathematical Framework, Dan Gabriel Cacuci
Introducing The Second-Order Features Adjoint Sensitivity Analysis Methodology For Neural Ordinary Differential Equations—I: Mathematical Framework, Dan Gabriel Cacuci
Faculty Publications
This work introduces the mathematical framework of the novel “First-Order Features Adjoint Sensitivity Analysis Methodology for Neural Ordinary Differential Equations” (1st-FASAM-NODE). The 1st-FASAM-NODE methodology produces and computes most efficiently the exact expressions of all of the first-order sensitivities of NODE-decoder responses with respect to the parameters underlying the NODE’s decoder, hidden layers, and encoder, after having optimized the NODE-net to represent the physical system under consideration. Building on the 1st-FASAM-NODE, this work subsequently introduces the mathematical framework of the novel “Second-Order Features Adjoint Sensitivity Analysis Methodology for Neural Ordinary Differential Equations (2nd-FASAM-NODE)”. The 2nd-FASAM-NODE methodology efficiently computes the exact expressions …
The Relationship Between A Transient Scientific Phenomenon And Local Journalism At The Beginning Of The Gilded Age, Thomas Hockey
The Relationship Between A Transient Scientific Phenomenon And Local Journalism At The Beginning Of The Gilded Age, Thomas Hockey
Faculty Publications
In the United States, the nineteenth century was the halcyon era for local newspapers. These publications were the primary source of public information at a time when other periodicals and books had low circulation. The purpose of this paper is to explore how local journalism in the nineteenth-century United States dealt with an occasion outside the boundaries of the commonplace: an unfamiliar natural phenomenon. My example is the total solar eclipse of 7 August 1869. Editors and journalists of the time largely were unaccustomed to covering celestial events. Nevertheless, they sensed—correctly—an interest in the solar eclipse. Articles about the approaching …
The Pagan Reception Of Judaism From The Sibylline Oracles: Insights From Pseudo-Seneca’S Octavia Regarding The Creation And Circulation Of Oral Sibylline Oracles By The Plebs, Kenneth Atkinson
Faculty Publications
According to tradition, the original collection of Sibylline Books acquired by the Roman monarch Tarquinius Priscus, which were kept in the Temple of Jupiter in the capital, were lost in the fire of 83 BCE. In 76 BCE, the Senate ordered the college of the quindecimviri to travel to the traditional centers of Sibylline activity in the East to find Sibylline Oracles to replace those destroyed in the fire. According to Lactantius, these officials collected many Oracles from private individuals. This reference suggests that Sibylline Oracles circulated widely. However, based on the witnesses regarding their consultation, it appears that the …
An Account Of The 1453 Ce Ottoman Siege Of Constantinople Interpreted Through A First Century Bce Jewish Text: How An Ancient Collection Of Second Temple Period Poems Changed The Course Of Western Civilization, Kenneth Atkinson
Faculty Publications
On 29 May 1453 CE, the besieged Christian occupants of Constantinople — the capital of the Byzantine Empire and the last surviving portion of the former Roman Empire — knew the end was near when they heard 50,000-80,000 angry Ottoman soldiers, including 5,000 to 10,000 of the elite Janissaries — the Sultan’s shook troops — preparing to breach its walls after a 53-day siege. The 7,000-man army defending the city knew that all was lost. The 21-year-old Sultan Mehmet II — given the sobriquet “the Conqueror” for capturing the city — leveled the roads so his army could reach Constantinople’s …

Introducing The Second-Order Features Adjoint Sensitivity Analysis Methodology For Neural Ordinary Differential Equations—Ii: Illustrative Application To Heat And Energy Transfer In The Nordheim–Fuchs Phenomenological Model For Reactor Safety, Dan Gabriel Cacuci
Faculty Publications
This work presents an illustrative application of the newly developed “Second-Order Features Adjoint Sensitivity Analysis Methodology for Neural Ordinary Differential Equations (2nd-FASAM-NODE)” methodology to determine most efficiently the exact expressions of the first- and second-order sensitivities of NODE decoder responses to the neural net’s underlying parameters (weights and initial conditions). The application of the 2nd-FASAM-NODE methodology will be illustrated using the Nordheim–Fuchs phenomenological model for reactor safety, which describes a short-time self-limiting power transient in a nuclear reactor system having a negative temperature coefficient in which a large amount of reactivity is suddenly inserted. The representative model responses that will …
Are Mondays Different? Evidence From Initial Public Offerings, Abu Chowdhury, Mika Vaihekoski, Mir Zaman
Are Mondays Different? Evidence From Initial Public Offerings, Abu Chowdhury, Mika Vaihekoski, Mir Zaman
Faculty Publications
This paper investigates how and why initial public offerings (IPOs) issued on Mondays differ from those on other days. We provide evidence that Monday IPOs make a significantly larger number of filing price amendments during the road show and set offer prices that exceed the filing price range, resulting in higher positive offer price revisions. We also find that Monday IPOs receive less analyst coverage than other-day IPOs, despite their underwriting fees being the same and their total underwriter compensation being higher. Therefore, Monday IPOs are more likely to change lead underwriters in subsequent equity offerings and have a higher …

The Association Between Infant Non-Nutritive Suck And Oral Motor Development, Ross Westemeyer, Morgan Hines, Alaina Martens, Emily Zimmerman
Faculty Publications
This study investigated if non-nutritive suck (NNS) at 3 months is related to subsequent oral motor and motor skills using caregiver-reported scores on the Child Oral and Motor Proficiency Scale (ChOMPS) at 12 months in a cohort of 69 full-term infants and their caregivers. Longer NNS burst durations were associated with lower oral motor coordination and total ChOMPS scores. More NNS cycles per minute was associated with lower complex motor movement scores. More NNS bursts, cycles per burst, and cycles per minute were related with lower total ChOMPS scores. Early NNS outcomes can provide valuable insight in future neuromotor development.
Roman History In Sibylline Oracle 13: A Palestinian Jewish Perspective On Emperors, Usurpers, And Saviors During The Third Century Ce (Part Two: From Decius To Odenath Of Palmyra), Kenneth Atkinson
Faculty Publications
Sibylline Oracle 13 is a remarkable historical document that contains a unique perspective on the poorly documented period of Roman history known as the “Crisis of the Third Century (235-284 CE), which began with the assassination of the Roman emperor Severus Alexander (222-235 CE), the last ruler of the Severan dynasty. This turbulent era was marked by nearly fifty years of civil wars, barbarian invasions, rebellions, and approximately twenty-six claimants to the throne. Although the end of this turmoil under Diocletian (284-305 CE) is well known, we have little information about much of this century, particularly its first decades. The …

Independent engagement can be challenging for K-12 online students. Parents’ physical presence makes them an important source of engagement support. Previous research on parental support in online courses is limited and focused on asynchronous learning within a single program. Since the COVID-19 pandemic, online enrollments have grown and instructional modalities have evolved. To better understand parental support post-Covid, we interviewed 21 parents across eight online programs with asynchronous, synchronous, and bichronous course offerings. Parents identified their affective, behavioral, cognitive, and other support roles. Implications for parental roles in addressing the academic engagement gap are provided to both researchers and practitioners.

Impact Of Vaporization On Drop Aerobreakup, B. Boyd, S. Becker, Yue Stanley Ling
Impact Of Vaporization On Drop Aerobreakup, B. Boyd, S. Becker, Yue Stanley Ling
Faculty Publications
Aerodynamic breakup of vaporizing drops is commonly seen in many spray applications. While it is well known that vaporization can modulate interfacial instabilities, the impact of vaporization on drop aerobreakup is poorly understood. Detailed interface-resolved simulations were performed to systematically study the effect of vaporization, characterized by the Stefan number, on the drop breakup and acceleration for different Weber numbers and density ratios. It is observed that the resulting asymmetric vaporization rates and strengths of Stefan flow on the windward and leeward sides of the drop hinder bag development and prevent drop breakup. The critical Weber number thus generally increases …

Bound States And Particle Production By Breather-Type Background Field Configurations, Abhishek Rout, Brett Altschul
Faculty Publications
We investigate the interaction of fermion fields with oscillating domain walls, inspired by breather-type solutions of the sine-Gordon equation, a nonlinear system of fundamental importance. Our study focuses on the fermionic bound states and particle production induced by a time-dependent scalar background field. The fermions couple to two domain walls undergoing harmonic motion, and we explore the resulting dynamics of the fermionic wave functions. We demonstrate that while fermions initially form bound states around the domain walls, the energy provided by the oscillatory motion of the scalar field induces an outward flux of fermions and antifermions, leading to particle production …

In this study, we consider three different machine-learning methods—a three-hidden-layer neural network, support vector regression, and Gaussian process regression—and compare how well they can learn from a synthetic data set for proton acceleration in the Target Normal Sheath Acceleration regime. The synthetic data set was generated from a previously published theoretical model by Fuchs et al. 2005 that we modified. Once trained, these machine-learning methods can assist with efforts to maximize the peak proton energy, or with the more general problem of configuring the laser system to produce a proton energy spectrum with desired characteristics. In our study, we focus …

Strategies To Alleviate Flickering: Bayesian And Smoothing Methods For Deep Learning Classification In Video, Noah Miller, Glen Ryan Drumm, Lance Champagne, Bruce A. Cox, Trevor Bihl
Faculty Publications
Excerpt: Increasing reliance on autonomous systems requires confidence in the accuracies produced from computer vision classification algorithms. Computer vision (CV) for video classification provides phenomenal abilities, but it often suffers from “flickering” of results. Flickering occurs when the CV algorithm switches between declared classes over successive frames. Such behavior causes a loss of trust and confidence in their operations.

We introduce what we believe to be novel spectral light detection and ranging (LiDAR) architectures that enable ultra-compact systems by a transition from spectral signal processing in space (gratings) to processing in time. The architectures leverage temporal dispersion and the unique spectro-temporal waveforms produced from the cascaded Raman scattering generated in the (H2) filled hollow core fiber. The characterized Raman source yields as many as six Raman orders from 1.06-1.70 μm; their unique spectro-temporal waveforms are measured. System performance simulations based on measured Raman waveforms show that high accuracy measurement of range and reflectivity are possible with proper …

In this paper, we use wave-optics simulations to explore the limitations of beam-control compensation. We evaluate performance in terms of the normalized power in a diffraction-limited bucket for the cases of no beam-control compensation, perfect phase compensation, and perfect full-field compensation. From these results, we are able to arrive at the following conclusions: (1) without any form of beam-control compensation, performance begins to degrade when D/r0 > 1; (2) with perfect phase compensation, performance begins to degrade when D/r0 > 1 and (λ/r0)/θ0 > 1; and (3) with perfect full-field compensation, performance begins to degrade when D/r0 …
