Effect Of Rice Planting Date And Optimal Planting Window For Southwest Louisiana, Tommaso Cerioli, Thanos Gentimis, Steven D. Linscombe, Adam N. Famoso

Faculty Publications

Rice (Oryza sativa L.) yield and grain quality are highly influenced by the planting date; thus, it is crucial to determine the optimal planting window for an area of cultivation. In this study, date of planting experiments conducted at the Louisiana State University (LSU) AgCenter Rice Research Station from 2011 to 2018 were analyzed to quantify the effect of planting date, genotype, and year on key agronomic traits. Planting date was strongly associated with yield across every year, explaining 55.6% of the overall phenotypic variation. A clear relationship was observed between later plantings and reduced yields; and the highest yields …

Finite Element Approximation Of Nonlocal Dynamic Fracture Models, P. K. Jha, R. Lipton

Faculty Publications

In this work we estimate the convergence rate for time stepping schemes applied to nonlocal dynamic fracture modeling. Here we use the nonlocal formulation given by the bond based peridynamic equation of motion. We begin by establishing the existence of H2 peridynamic solutions over any finite time interval. For this model the gradients can become large and steep slopes appear and localize when the non-locality of the model tends to zero. In this treatment spatial approximation by finite elements are used. We consider the central-difference scheme for time discretization and linear finite elements for discretization in the spatial variable. The …

Revamping Ecosystem Services Through Agroecology—The Case Of Cereals, Gomathy Sethuraman, Nurul Amalina Mohd Zain, Sumiani Yusoff, Yin Mei Ng, Niranjan Baisakh, Acga Cheng

Faculty Publications

Globally, farming systems are mostly dominated by monoculture, which has the advantage of profitability at the expense of ecological systems. Recent years have witnessed an increasing mo-mentum in global efforts to deploy sustainable agriculture practices that mimic ecological processes, with agroecology at the forefront. In addition to the ecological aspect, agroecology also encompasses economic and social aspects targeting the whole food system. Transformative agroecology has been recognized as a stepping stone to achieving several Sustainable Development Goals (SDGs), due to its great potential to build climate change-resilient farming systems while enhancing ecosystem services and reducing biodiversity loss. Nonetheless, the available …

Second Languange Acquisition Of /S/ -Weakinging In A Study Abroad Context, Earl K. Brown, Alicia Harley, Bret Linford

Faculty Publications

This study examines the second language (L2) development of variable /s/-weakening in the spontaneous speech of L2 learners of Spanish who studied abroad in either Dominican Republic, where /s/-weakening is widespread, or central Spain, where /s/-weakening is much less common. Learners’ realizations of /s/ were coded impressionistically and acoustically by measuring voicing, center of gravity, and duration. The results show that regardless of the study abroad location, students did not change the amount of sibilance they produced over time. However, they became more nativelike with respect to /s/-voicing and duration. Additionally, whereas some linguistic factors were found to significantly constrain …

The Lost Promise Of Disability Rights, Claire Raj

Faculty Publications

Children with disabilities are among the most vulnerable students in public schools. They are the most likely to be bullied, harassed, restrained, or segregated. For these and other reasons, they also have the poorest academic outcomes. Overcoming these challenges requires full use of the laws enacted to protect these students’ affirmative right to equal access and an environment free from discrimination. Yet, courts routinely deny their access to two such laws—the Americans with Disabilities Act (ADA) and section 504 of the Rehabilitation Act of 1973 (section 504).

Courts too often overlook the affirmative obligations contained in these two disability rights …

Faculty Publications

The world’s food systems and environments have been changing dramatically, concomitant with changes in overand undernutrition. We elaborate the science of food choice to better understand, analyze, and respond to relationships between changing food environments and food choice. The science of food choice is concerned with generating knowledge about causal drivers of food choice decision making processes and behavior within immediate food and social environments. Three fundamental and interconnected questions undergird this science; 1) what do people eat from the options available and accessible?; 2) how do people interact with food environments?; and 3) why do people decide to acquire, …

Faculty Publications

One in 113-178 females worldwide carry a premutation allele on the FMR1 gene. The FMR1 premutation is linked to neurocognitive and neuromotor impairments, although the phenotype is not fully understood, particularly with respect to age effects. This study sought to define oculomotor response inhibition skills in women with the FMR1 premutation and their association with age and fall risk. We employed an antisaccade eye-tracking paradigm to index oculomotor inhibition skills in 35 women with the FMR1 premutation and 28 control women. The FMR1 premutation group exhibited longer antisaccade latency and reduced accuracy relative to controls, indicating deficient response inhibition skills. …

The Costs Of Dissent: Protest And Civil Liabilities, Timothy Zick

Faculty Publications

This Article examines the civil costs and liabilities that apply to individuals who organize, participate in, and support protest activities. Costs ranging from permit fees to punitive damages significantly affect First Amendment speech, assembly, and petition rights. A variety of common law and statutory civil claims also apply to protest activities. Plaintiffs have recently filed a number of new civil actions negatively affecting protest, including "negligent protest," "aiding and abetting defamation," "riot boosting," "conspiracy to protest," and "tortious petitioning." The labels are suggestive of the threats these suits pose to First Amendment rights. All of these costs and liabilities add …

We examined how children (n=448) who met research criteria for separate vs. co-occurring DLD and dyslexia performed on school-based measures of academic functioning in reading and math between second and fourth grades. Growth curve models were used to examine the overall form of growth and differences between groups. Children with DLD and/or dyslexia in second grade showed early and persistent deficits on school-administered measures of reading and math. In second grade, children with typical development (TD) scored significantly higher than all other groups, children with DLD+dyslexia scored significantly lower than all other groups, and children with dyslexia-only and DLD-only did …

Annihilation And Control Of Chiral Domain Walls With Magnetic Fields, Sunil K. Karna, Madalynn Marshall, Weiwei Xie, Lisa Debeer-Schmitt, David P. Young, Ilya Vekhter, William A. Shelton, Andras Kovács, Michalis Charilaou, John F. Ditusa

Faculty Publications

The control of domain walls is central to nearly all magnetic technologies, particularly for information storage and spintronics. Creative attempts to increase storage density need to overcome volatility due to thermal fluctuations of nanoscopic domains and heating limitations. Topological defects, such as solitons, skyrmions, and merons, may be much less susceptible to fluctuations, owing to topological constraints, while also being controllable with low current densities. Here, we present the first evidence for soliton/soliton and soliton/antisoliton domain walls in the hexagonal chiral magnet Mn1/3NbS2 that respond asymmetrically to magnetic fields and exhibit pair-annihilation. This is important because it suggests the possibility …

Compoundhetvip: Compound Heterozygous Variant Identification Pipeline, Dustin B. Miller, Stephen R. Picollo

Urban-Rural Differences In Covid-19 Exposures And Outcomes In The South: A Preliminary Analysis Of South Carolina, Qian Huang, Sarah Jackson, Sahar Derakhshan, Logan Lee, Erika Pham, Amber Jackson, Susan L. Cutter

Faculty Publications

As the COVID-19 pandemic moved beyond the initial heavily impacted and urbanized Northeast region of the United States, hotspots of cases in other urban areas ensued across the country in early 2020. In South Carolina, the spatial and temporal patterns were different, initially concentrating in small towns within metro counties, then diffusing to centralized urban areas and rural areas. When mitigation restrictions were relaxed, hotspots reappeared in the major cities. This paper examines the county-scale spatial and temporal patterns of confirmed cases of COVID-19 for South Carolina from March 1st—September 5th, 2020.

Ensemble Machine Learning Assisted Reservoir Characterization Using Field Production Data–An Offshore Field Case Study, Baozhong Wang, Jyotsna Sharma, Jianhua Chen, Patricia Persaud

Faculty Publications

Estimation of fluid saturation is an important step in dynamic reservoir characterization. Machine learning techniques have been increasingly used in recent years for reservoir saturation prediction workflows. However, most of these studies require input parameters derived from cores, petrophysical logs, or seismic data, which may not always be readily available. Additionally, very few studies incorporate the production data, which is an important reflection of the dynamic reservoir properties and also typically the most frequently and reliably measured quantity throughout the life of a field. In this research, the random forest ensemble machine learning algorithm is implemented that uses the field-wide …

Differential Relationships Of Stress And Hiv Disclosure By Gender: A Person Centered Longitudinal Study, Chengbo Zeng, Shan Qiao Ph.D., Xiaoming Li Ph.D., Xueying Yang Ph.D., Zhiyong Shen, Yuejiao Zhou

Faculty Publications

Juicing vegetables is thought to be an anticancer treatment. Support exists for a rank order of anticancer greens (kale > dandelion > lettuce > spinach) based on degrees of bioavailability of different phytochemicals, also offset by some noxious molecules (i.e., calcium-oxalate). We developed a new in vitro transepithelial anti-neuroblastoma model system. The juices were diluted as predicted once in the small intestine. They were applied to apical Caco-2Bbe1 cells atop dividing SH-SY5Y neuroblastoma cells, and changes in transepithelial electrical resistance (TEER) and cell growth were considered with juice spectroscopies. Studied first in monoculture, kale and dandelion were the most cytostatic juices on SH-SY5Ys, …
