A Theory Of Genetic Dimensions In The Law, Yaniv Heled, Liza Vertinsky, Ana Santos Rutschman

Faculty Publications

Since the biotechnology revolution of the 1970s, genetic science and genetic technology have captured the public imagination. They have become a centerpiece of how we understand ourselves, our relationship with other humans, other living beings, our environment, and—indeed—with the universe. Through this evolution of understanding, genetic phenomena have acquired many meanings, some rooted in objective reality and others subjective and dependent on individual perceptions and sentiments.

However, legal decision-making and policymaking have not kept pace and reflect only a partial understanding of the multiple dimensions of genetic phenomena, which are forced into narrowing legal pathways, neglecting vital interests. As the …

Squeezing Blood From Stones? A Comparative Analysis Of Tax Relief For Victim-Survivors In Australia And The United States, Christine Speidel, Leslie Book, Ann Kayis-Kumar

Faculty Publications

Women who leave abusive relationships generally do so with increased debt, reduced assets, insecure housing and longer-term economic insecurity. Most of these women will be experiencing economic abuse even after the relationship has ended, and many cite financial instability as a key factor driving them back into abusive relationships. So, it is imperative that the tax and transfer system helps rather than hinders (albeit inadvertently) this cohort of financially vulnerable taxpayers. However, this is not always the case, with victim-survivors of economic abuse often liable for tax debts incurred by former partners operating businesses in the victim-survivor's name.

Estimation Of Land Displacement In East Baton Rouge Parish, Louisiana, Using Insar: Comparisons With Gnss And Machine Learning Models, Ahmed Abdalla, Siavash Shami, Mohammad Amin Shahriari, Mahdi Khoshlahjeh Azar

Faculty Publications

Subsidence in southeastern Louisiana is a significant geological issue caused by natural and human-induced factors like low-lying topography and groundwater pumping. Human activities also led to coastal land loss and reduced sediment supply. Satellite-based technologies such as Global Navigation Satellite Systems (GNSS) and Interferometric Synthetic Aperture Radar (InSAR) are used to monitor subsidence. Louisiana has about 130 continuously operating reference stations (CORS) monitoring subsidence statewide. GNSS provides accurate point measurements but limited spatial coverage. InSAR, however, detects ground deformation over large areas using satellite-based radar imagery. In response to this advantage, we employed Sentinel-1 SAR images from 2017 to 2021 …

Leveraging Designed Simulations And Machine Learning To Develop A Surrogate Model For Optimizing The Gas–Downhole Water Sink–Assisted Gravity Drainage (Gdws-Agd) Process To Improve Clean Oil Production, Watheq J. Al-Mudhafar, Dandina N. Rao, Andrew K. Wojtanowicz

Faculty Publications

The Gas and Downhole Water Sink–Assisted Gravity Drainage (GDWS-AGD) process addresses gas flooding limitations in reservoirs surrounded by infinite-acting aquifers, particularly water coning. The GDWS-AGD technique reduces water cut in oil production wells, improves gas injectivity, and optimizes oil recovery, especially in reservoirs with high water coning. The GDWS-AGD process installs two 7-inch production casings bilaterally. Then, two 2-3/8-inch horizontal tubings are completed. One tubing produces oil above the oil–water contact (OWC) area, while the other drains water below it. A hydraulic packer in the casing separates the two completions. The water sink completion uses a submersible pump to prevent …

Heterogeneous Mantle Effects On The Behaviour Of Smks Waves And Outermost Core Imaging, Daniel A. Frost, Edward J. Garnero, Neala Creasy, Jonathan Wolf, Ebru Bozdağ, Maureen D. Long, Adeolu Aderoju, Reynaldo Vite

Faculty Publications

Seismic traveltime anomalies of waves that traverse the uppermost 100–200 km of the outer core have been interpreted as evidence of reduced seismic velocities(relative to radial reference models) just below the core–mantle boundary (CMB). These studies typically investigate differential traveltimes of SmKS waves, which propagate as P waves through the shallowest outer core and reflect from the underside of the CMB m times. The use of SmKS and S(m-1)KS differential traveltimes for core imaging are often assumed to suppress contributions from earthquake location errors and unknown and unmodelled seismic velocity heterogeneity in the mantle. The goal of this study is …

Borderline Personality Disorder Subtypes And Public Stigma, Seth A. Brown

Faculty Publications

Despite high public stigma towards individuals with borderline personality disorder (BPD), no research has examined whether stigma differs among the various proposed BPD subtypes. The primary purpose of this research was to examine two potential contributors to stigma towards individuals with BPD: 1) gender, and 2) BPD subtype of the individuals. The three subtypes utilized in this study were emotional, low anxiety, and inhibited (Sleuwaegen, 2018). A total of 415 participants read 1 of 6 randomly assigned vignettes about an individual and then completed the Attribution Questionnaire which encompasses 6 aspects of stigma.

Supernova remnants (SNRs) provide insights into cosmic-ray acceleration and magnetic field dynamics at shock fronts. Recent X-ray polarimetric measurements by the Imaging X-ray Polarimetry Explorer (IXPE) have revealed radial magnetic fields near particle acceleration sites in young SNRs, including Cassiopeia A, Tycho, and SN 1006. We present here the spatially resolved IXPE X-ray polarimetric observation of the northwestern rim of SNR RX J1713.7–3946. For the first time, our analysis shows that the magnetic field in the particle acceleration sites of this SNR is oriented tangentially with respect to the shock front. Because of the lack of precise Faraday rotation measurements …

The Business Of Abortion: Access To Capital Post Dobbs, Itay Ravid, Jonathan Zandberg

Faculty Publications

Access to credit—that is, the ability to receive financial leverage that could help jump-start businesses—is one of the most significant barriers preventing millions of American women from opening new businesses. Congress has attempted to address this issue since the 1970s, with legislation like the Equal Credit Opportunity Act (ECOA). Nevertheless, studies continue to show a persistent gender gap in access to credit. Scholars have offered a host of explanations for this gap, focusing on both the supply and demand sides of the equation.

This Article contributes to this growing scholarly exploration by offering a new, overlooked explanation for this gap: …

Hydrometeorological Drivers Of The 2023 Louisiana Water Crisis, P. W. Miller, M. Hiatt

Faculty Publications

During summer and fall 2023, Louisiana experienced a historic local drought while dry conditions elsewhere in the central US withheld vital runoff from the Mississippi River, leading to below-normal discharge into the Gulf of Mexico. Thus, by late October 2023, Louisiana was gripped by two super-imposed water crises: a severe local drought and saltwater contamination in the Mississippi River channel. This study frames the development of the water emergency through the lens of flash drought using the Evaporative Demand Drought Index (EDDI). The EDDI shows south Louisiana experience a flash drought during June 2023, while the Mississippi River basin was …

Top-Down Control Of Ammonia Oxidizers By Grazing In The North Pacific, Silin Ni, Min Nina Xu, Moge Du, Edward A. Laws, Shuh Ji Kao

Faculty Publications

The impact of grazing pressure on ammonia oxidizers (AO) has never been quantified in the field. Here we develop a new method to quantify the grazing rates on AO in aquatic systems. We introduce ¹⁵NH4⁺ tracer into the traditional dilution experiments to measure AO's apparent growth rates by using the end-product of ¹⁵NH4⁺ oxidation, that is, ¹⁵NOx⁻. Field studies in the North Pacific revealed that ¹⁵NOx⁻ in the end-product was sensitive enough to detect AO's grazing rates. Experiments from the lower euphotic zone showed NH4⁺ replete growth rates of 0.40 …

Mobile devices (e.g., tablets and smartphones) have been rapidly integrated into the lives of children and have impacted howchildren engage with digital media. The portability of these devices allows for sporadic, on-demand interaction, reducing theaccuracy of self-report estimates of mobile device use. Passive sensing applications objectively monitor time spent on a givendevice but are unable to identify who is using the device, a significant limitation in child screen time research. Behavioralbiometric authentication, using embedded mobile device sensors to continuously authenticate users, could be applied toaddress this limitation. This study examined the preliminary accuracy of machine learning models trained on iPad …

Communication—The Development Of A Stable And Practical Saturated Reference Electrode For Molten Chloride Salt Systems, J. Marvin Torrie, Ranon Fuller, Devin Rappleye

Faculty Publications

A simply constructed, stable, Ni/Ni²⁺ saturated reference electrode (SRE) has potential to measure thermodynamic behavior of molten chloride salts more reliably. Like the Ag/Ag⁺ reference electrode (RE), the Ni/Ni²⁺ SRE is made of commercially available materials. Initial experiments in molten CaCl2 and LiCl show the Ag/Ag⁺ RE potential drifting two times faster than the SRE. Furthermore, experiments show the replicability of SREs by comparing two Ni/Ni²⁺ SREs with different compositions of NiCl₂ which is supportive of saturated phase behavior.

Trophic Interactions In Microbiomes Influence Plant Host Population Size And Ecosystem Function, Jiaqi Tan, Na Wei, Martin M. Turcotte

Faculty Publications

Plant microbiomes that comprise diverse microorganisms, including prokaryotes, eukaryotes and viruses, are the key determinants of plant population dynamics and ecosystem function. Despite their importance, little is known about how species interactions (especially trophic interactions) between microbes from different domains modify the importance of microbiomes for plant hosts and ecosystems. Using the common duckweed Lemna minor, we experimentally examined the effects of predation (by bacterivorous protists) and parasitism (by bacteriophages) within microbiomes on plant population size and ecosystem phosphorus removal. Our results revealed that the addition of predators increased plant population size and phosphorus removal, whereas the addition of parasites …

Effects Of Rf Signal Eventization Encoding On Device Classification Performance, Michael J. Smith, Michael A. Temple, James W. Dean

Faculty Publications

The results of first-step research activity are presented for realizing an envisioned “event radio” capability that mimics neuromorphic event-based camera processing. The energy efficiency of neuromorphic processing is orders of magnitude higher than traditional von Neumann-based processing and is realized through synergistic design of brain-inspired software and hardware computing elements. Relative to event-based cameras, the development of event-based hardware devices supporting Radio Frequency (RF) applications is severely lagging and considerable interest remains in obtaining neuromorphic efficiency through event-based RF signal processing. In the Operational Technology (OT) protection arena, this includes efficient software computing capability to provide reliable device classification. A …

Narrative Analysis In Individuals With Parkinson’S Disease Following Intensive Voice Treatment: Secondary Outcome Variables From A Randomized Controlled Trial, Amy E. Ramage, Kathryn J. Greenslade, Kaila Cote, Jessica N. Lee, Cynthia M. Fox, Angela Halpern, Lorraine O. Ramig

Faculty Publications

Communication is often impaired in individuals with Parkinson’s disease (PD), typically secondary to sensorimotor deficits impacting voice and speech. Language may also be diminished in PD, particularly for production and comprehension of verbs. Evidence exists that verb processing is influenced by motor system modulation suggesting that verb deficits in PD are underpinned by similarities in the neural representations of actions that span motor and semantic systems. Conversely, subtle differences in cognition in PD may explain difficulty in processing of complex syntactic forms, which increases cognitive demand and is linked to verb use. Here we investigated whether optimizing motor system support …

Toxoplasma gondii is a parasitic infection that can be transmitted in utero, resulting in fetal chorioretinitis and other long-term neurological outcomes. If diagnosed early, pregnancy-safe chemotherapeutics can prevent vertical transmission. Unfortunately, diagnosis of acute, primary infection among pregnant women remains neglected, particularly in low-and-middle-income countries. Clinically actionable diagnosis is complex due to the commonality of infection during childhood and early adulthood which spawn long-last antibody titers and historically unreliable direct molecular diagnostics. The current study employed a cross-sectional T. gondii perinatal surveillance study using digital PCR, a next generation molecular diagnostic platform, and a maternal-fetal outcomes survey to ascertain …

Faculty Publications

The phase transitions in MnNiGe compounds were explored by manipulating the heat treatment conditions and through hydrostatic pressure application. As the quenching temperature increased, both the first-order martensitic structural transition temperatures and magnetic transition temperatures decreased relative to those in the slowly-cooled samples. When the samples were quenched from 1200 °C, the first-order martensitic structural transition temperature lowered by more than 200 K. The structural transitions also shifted to lower temperature with the application of hydrostatic pressure during measurement. Temperature-dependent x-ray diffraction results reveal that the changes of the cell parameters resulting from the structural transitions are nearly identical for …
