Abstract: Sugarcane (Saccharum officinarum) is Louisiana's number one row crop. Growing and processing sugarcane produces significant amounts of byproducts, including bagasse, crop residue, molasses, filter-press mud, and boiler fly ash. These products represent an important opportunity to generate value-added and specialty products and enhance sugarcane's sustainability by facilitating a circular economy, where agricultural by-products are reused instead of disposing them (linear economy), in order to reduce resource use and energy demand. Examples of value-added products range from biochar, construction materials, animal feed, biofuels, nanoparticles, and fertilizer. Paramount to the success of the bio-based circular economy is creating useful products that …

Substituent Effects On The Photophysical Properties Of A Series Of 8(Meso)-Pyridyl-Bodipys: A Computational Analysis Of The Experimental Data †, Petia Bobadova-Parvanova, Dylan Goliber, Elijuah Hernandez, Daniel Lamaster, Maria Da Graça H. Vicente

Faculty Publications

Recently, a series of 8(meso)-pyridyl-BODIPYs (2-pyridyl, 3-pyridyl, and 4-pyridyl) and their 2,6-substituted derivatives were synthesized and their structure and photophysical properties were studied both experimentally and computationally. One of the main observed trends was that the 2-pyridyl-BODIPYs were consistently less fluorescent than their 3-pyridyl and 4-pyridyl analogs, regardless of the 2,6-substituents. Herein, we extend our previous computational studies and model not only the ground but also the excited states of the entire series of previously synthesized meso-pyridyl-BODIPYs with the aim of explaining the observed differences in the emission quantum yields. To better understand the trends and the effect of 2- …

Faculty Publications

Environmental concerns are growing in parts of the rural United States as drinking water wells become contaminated with agrichemicals, and climate change impacts such as drought and extreme rain events disrupt farming practices. Analyzing in-depth interviews with 29 U.S. rural journalists, we explore the role rural journalists play when reporting on the environment as it relates to agricultural issues. Findings show that reporting about the environment—such as weather, climate change, water shortages, and droughts—appear in rural journalists' stories given those topics' relevance to their rural communities and the social systems forces exerting influence on journalists, yet rural journalists often do …

Controlling Anti-Asian Conduct On College Campuses: Can Including Ethnic Studies Programs Help?, Hani Morgan

Faculty Publications

The COVID-19 pandemic has triggered hostile acts against Asian college students. One of the ways to respond to these acts is to increase Asian American ethnic studies programs and courses. Although critics argue that ethnic studies cause divisiveness, research indicates that they are beneficial to students from all groups. University administrators may fear implementing these programs because they sometimes associate them with the violence that occurred during the late 1960s when students demanded ethnic studies to be included in the college curriculum. But this to a great extent by the poor representation of racial minority groups in the curriculum and …

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 …

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 …

Redressing Judicial Misbehavior: An Integrated Approach To Judicial Immunity, Nancy Amoury Combs

Faculty Publications

Immunities generate intense public interest and controversy. Whether it is the sweeping presidential immunity that former President Trump has claimed or the qualified immunity that rogue police invoke to evade financial responsibility for their brutality, immunities stand as a highly contested aspect of the American legal system. Judicial immunity incites similar controversy. American judges possess absolute immunity from civil suits for their judicial acts, so victims are barred from seeking civil compensation, even against judges who engage in purposeful or malicious misconduct from the bench. For decades scholars have sought to curtail absolute judicial immunity, but they have overlooked a …

Law And Equity On Appeal, Aaron-Andrew P. Bruhl

Faculty Publications

Most lawyers know that the Federal Rules of Civil Procedure merged the divergent trial procedures of the common law and of equity, but fewer are familiar with the development of federal appellate procedure. Here too there is a story of the merger of two distinct systems. At common law, a reviewing court examined the record for errors of law after the final trial judgment. In the equity tradition, an appeal was a rehearing of the law and the facts that aimed at achieving justice and did not need to await a final judgment. Unlike the story of federal trial procedure, …

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 …

Roman History In Sibylline Oracle 13: A Palestinian Jewish Perspective On Emperors, Usurpers, And Saviors During The Third Century Ce (Part One: From Maximus I “Thrax” To Philip I “The Arab”), Kenneth Atkinson

Faculty Publications

The period commonly known as the “Crisis of the Third Century” (235-284 CE) 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 war, barbarian invasions, rebellions, and political and social unrest caused by approximately twenty-six claimants to the imperial throne. Although the end of this age of disorder under Diocletian (284-305 CE) is well-known, we have little information about much of the third century CE, particularly its first decades. This study examines book 13 of the Sibylline oracles, which …

This study is dedicated to the economic valuation of human capital (HC) in the regions where the Indigenous peoples of Kamchatka reside. The entire Kamchatksky Krai is considered an Indigenous people’s ancestral territory. However, in this study, only municipalities whose population is more than one-third Indigenous were chosen for the assessment. This includes six municipal districts and one urban district (Aleytsky, Bystrinsky, Karaginsky, Olyutorsky, Penzhinsky, and Tigilsky municipal districts and Palana urban district). The study employs statistical analysis and integrated, situational approaches: the investment approach was deemed the most appropriate tool for the economic assessment of HC in Indigenous territories. …

Spatial Pattern And Differential Expression Analysis With Spatial Transcriptomic Data, Fei Qin, Xizhi Luo, Bo Cai Ph.D., Feifei Xiao, Guoshuai Cai

Faculty Publications

The emergence of spatial transcriptomic technologies has opened new avenues for investigating gene activities while preserving the spatial context of tissues. Utilizing data generated by such technologies, the identification of spatially variable (SV) genes is an essential step in exploring tissue landscapes and biological processes. Particularly in typical experimental designs, such as case-control or longitudinal studies, identifying SV genes between groups is crucial for discovering significant biomarkers or developing targeted therapies for diseases. However, current methods available for analyzing spatial transcriptomic data are still in their infancy, and none of the existing methods are capable of identifying SV genes between …

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 …

Effective Support Strategies Serving Diverse Teacher Candidates In Paraprofessional Teacher Education Programs, Angela Christine Griner, Debra K. Wellman

Paraprofessionals remain a rich resource for our children and our school communities. Teacher education programs that have sought to provide pathways to teaching certification for paraprofessionals recognize this. Over the last 25 years, research has shown well-documented models for programs and strategies that support candidates in these programs, as well as the obstacles and challenges those programs and participants face. This article presents a descriptive case study of the first three years of a para-to-teacher program, across three cohorts of participants at a small liberal arts institution. Implications for best practices tied to collaborative leadership, relational approaches, and collaborative program …

Applying Machine‐Learning Methods To Laser Acceleration Of Protons: Lessons Learned From Synthetic Data, Ronak Desai, Thomas Zhang, J. J. Felice, Ricky Oropeza, Joseph R. Smith, Alona Kryshchenko, Chris Orban, Michael L. Dexter, Anil K. Patnaik

Faculty Publications

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 …

Sound Innovations For Biofabrication And Tissue Engineering, Mengxi Wu, Zhiteng Ma, Zhenhua Tian, Joseph Rich, Xin He, Jianping Xia, Ye He, Kaichun Yang, Shujie Yang, Kam W. Leong, Luke P. Lee, Tony Jun Huang

Faculty Publications

Advanced biofabrication techniques can create tissue-like constructs that can be applied for reconstructive surgery or as in vitro three-dimensional (3D) models for disease modeling and drug screening. While various biofabrication techniques have recently been widely reviewed in the literature, acoustics-based technologies still need to be explored. The rapidly increasing number of publications in the past two decades exploring the application of acoustic technologies highlights the tremendous potential of these technologies. In this review, we contend that acoustics-based methods can address many limitations inherent in other biofabrication techniques due to their unique advantages: noncontact manipulation, biocompatibility, deep tissue penetrability, versatility, precision …

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.

Limitations Of Beam-Control Compensation, Matthew Kalensky, Darren Getts, Matthias T. Banet, Derek J. Burrell, Milo W. Hyde, Mark F. Spencer

Faculty Publications

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/r_{0 …}
