Evaluation Of Viability Of E. Coli O157: H7 On Chlorine And Lactic Acid Treated Spinach Leaves Using Combined Propidium Monoazide Staining And Real-Time Pcr, Vijay Singh Chhetri, Yu Han, Marlene E. Janes, Achyut Adhikari

Faculty Publications

Sanitizer wash may induce bacterial pathogens on produce surfaces into a viable but-nonculturable (VBNC) state and may go undetected by conventional plating methods. This study investigated the effect of chlorine and lactic acid on the viability of E. coli O157: H7 on spinach leaves right after the treatment and during refrigerated storage using propidium monoazide staining and real-time PCR (PMA-qPCR). Baby spinach leaves inoculated with E. coli O157: H7 were washed with chlorine (100 ppm) and lactic acid (0.5%) for 5 min and 3 min, respectively. The residual effect of the treatments was examined by inoculating the sanitizer-treated leaves with …

Quasilinear Riccati-Type Equations With Oscillatory And Singular Data, Quoc Hung Nguyen, Nguyen Cong Phuc

Faculty Publications

We characterize the existence of solutions to the quasilinear Riccati-type equation [EQUATION PRESENTED] with a distributional or measure datum . Here divA(x) is a quasilinear elliptic operator modeled after the p-Laplacian (p > 1), and is a bounded domain whose boundary is sufficiently flat (in the sense of Reifenberg). For distributional data, we assume that p > 1 and q > p. For measure data, we assume that they are compactly supported in, p > 3n.2 2n-1 , and q is in the sub-linear range p -1 > q > 1.We also assume more regularity conditions on A and on δωω in this case.

Single nucleotide polymorphisms (SNPs) are highly abundant, amendable to high-throughput genotyping, and useful for a number of breeding and genetics applications in crops. SNP frequencies vary depending on the species and populations under study, and therefore target SNPs need to be carefully selected to be informative for each application. While multiple SNP genotyping systems are available for rice (Oryza sativa L. and its relatives), they vary in their informativeness, cost, marker density, speed, flexibility, and data quality. In this study, we report the development and performance of the Cornell-IR LD Rice Array (C7AIR), a second-generation SNP array containing 7,098 markers …

Conserved And Variable Responses Of The Gut Microbiome To Resistant Starch Type 2, Zachary A. Bendiks, Knud E.B. Knudsen, Michael J. Keenan, Maria L. Marco

Faculty Publications

Resistant starch type 2 (RS2), a dietary fiber comprised solely of glucose, has been extensively studied in clinical trials and animal models for its capacity to improve metabolic and systemic health. Because the health modulatory effects of RS2 and other dietary fibers are thought to occur through modification of the gut microbiome, those studies frequently include assessments of RS2-mediated changes to intestinal microbial composition and function. In this review, we identify the conserved responses of the gut microbiome among 13 human and 35 animal RS2 intervention studies. Consistent outcomes of RS2 interventions include reductions in bacterial α-diversity; increased production of …

We report on the discovery and validation of TOI 813 b (TIC55525572b), a transiting exoplanet identified by citizen scientists in data from NASA's Transiting Exoplanet Survey Satellite (TESS) and the first planet discovered by the Planet Hunters TESS project. The host star is a bright (V = 10.3 mag) subgiant (R* = 1.94 R☉, M☉ = 1.32 M☉). It was observed almost continuously by TESS during its first year of operations, during which time four individual transit events were detected. The candidate passed all the standard light curve-based vetting checks, and ground-based follow-up spectroscopy and speckle imaging enabled us to …

Established Adulthood: A New Conception Of Ages 30 To 45, Clare M. Mehta, Jeffrey Jensen Arnett, Carlie G. Palmer, Larry J. Nelson

Faculty Publications

In developed countries, the years from Age 30 to 45 are, for many, the most intense, demanding, and rewarding years of adult life. During this period of the life span most adults must negotiate the intersecting demands of progressing in a chosen career, maintaining an intimate partnership, and caring for children. Successes or difficulties in meeting these simultaneous demands have the potential to profoundly influence the direction of a person's adult life. As such, we believe that it is of critical importance to better understand this developmental period that we call established adulthood. This article provides a new theoretical …

Litigation As Parenting, Lisa Martin

Faculty Publications

Children have legal rights. Yet, children typically lack the legal capacity to represent their interests in courts. When federal courts are presented with children’s claims, the Federal Rules of Civil Procedure require courts to ensure that children’s legal interests are adequately protected. To do so, courts decide who can speak and make decisions for the child within the litigation. Federal Rule of Civil Procedure 17(c) maps out a loose process for addressing these concerns but fails to fully account for a critical factor in protecting child litigants: the decision making rights of parents.

Because parents have constitutionally protected authority to …

Magnetic Field–Driven Assembly And Reconfiguration Of Multicomponent Supraparticles, A. Al Harraq, J. G. Lee, B. Bharti

Faculty Publications

Suprastructures at the colloidal scale must be assembled with precise control over local interactions to accurately mimic biological complexes. The toughest design requirements include breaking the symmetry of assembly in a simple and reversible fashion to unlock functions and properties so far limited to living matter. We demonstrate a simple experimental technique to program magnetic field–induced interactions between metallodielectric patchy particles and isotropic, nonmagnetic “satellite” particles. By controlling the connectivity, composition, and distribution of building blocks, we show the assembly of three-dimensional, multicomponent supraparticles that can dynamically reconfigure in response to change in external field strength. The local arrangement of …

Revised Lewis Bending Stress Capacity Model, Edward E. Osakue

Faculty Publications

Background: During operation, cylindrical gearset experiences tangential, radial, and axial (helical gears only) force components that induce bending, compressive, and shear stresses at the root area of the gear tooth. Accurate estimation of the effective bending stress at the gear root is a challenge. Lewis was the first person who attempted estimating the root bending stress of spur gears with some reasonable accuracy. Various gear standards and codes in use today are modifications and improvements of the Lewis model.

Objective: This research aims at revising the Lewis model by making adjustments for dynamic loads, shear stresses, axial bending stress for …

From The Chalkboard To The Bank: Teaching Educational Leaders To Be Effective Fundraisers, Michael T. Miller, Mei-Yan Lu, G. David Gearhart

Faculty Publications

The effective use of financial resources is critical for all educational institutions, especially those K-12 schools that rely on public funding for their main operating revenue. As public entities and state governments increasingly struggle to find the revenue necessary to operate prisons, fund Medicaid/Medicare, improve an aging infrastructure, support social welfare programs, and recover from the Great Recession, educational institutions are finding themselves directly competing with other public agencies for scarce resources. These factors resulted in 29 states reducing funding for public education (Evans, Schwab & Wagner, 2019; Leachman, Masterson, & Figueroa, 2017). In the face of fierce competition, educational …

Impact Of Part Thickness And Drying Conditions On Saturation Limits In Binder Jet Additive Manufacturing, Nathan B. Crane

Faculty Publications

Binder jetting (BJ) is a high build-rate additive manufacturing process with growing commercial interest. Growth in BJ applications is driven by the use of finer powders and improved post-processing methods that can produce dense, homogenous final parts. However, understanding of the basic droplet/powder interaction is relatively limited. This paper considers the impact of in-process drying, part geometry, and droplet size on a key printing parameter: binder saturation. Parts of varying thicknesses are printed with a range of saturation levels under various heating conditions. The ratio of the printed part mass to the theoretical part mass is used to detect bleeding. …

Faculty Publications

This work applies the Second-Order Adjoint Sensitivity Analysis Methodology (2nd-ASAM) to compute the mixed 2nd-order sensitivities of a polyethylene-reflected plutonium (PERP) benchmark's leakage response with respect to the benchmark's imprecisely known isotopic number densities and the other benchmark imprecisely known parameters, including: (i) the 6 × 180 mixed 2nd-order sensitivities involving the total microscopic cross sections; (ii) the 6 × 21,600 mixed 2nd-order sensitivities involving the scattering microscopic cross sections; (iii) the 6 × 60 mixed 2nd-order sensitivities involving the fission microscopic cross sections; and (iv) the 6 × 60 mixed 2nd-order sensitivities involving the average number of neutrons produced …

Too Soon Forgot: The Ethics Of Remembering In Richard Iii, Now, And House Of Cards, L Monique Pittman

Faculty Publications

Three interconnected performances of Shakespeare's Richard III display the extreme hermeneutical volatility of representation when remediated through a celebrity's personal history. The film NOW: In the Wings on a World Stage (dir. Jeremy Whelehan, 2014) documents the Bridge Project Company's Richard III directed by Sam Mendes and starring Kevin Spacey (2011-12), a production launched at London's Old Vic and transferred to twelve cities across the globe. Just prior to the distribution of NOW, Netflix released its first season of House of Cards (2013) with Spacey as the politician, Francis Underwood, at the center of its seamy landscape. Spacey insists …

Machine Learning Modeling Of Horizontal Photovoltaics Using Weather And Location Data, Christil Pasion, Torrey J. Wagner, Clay Koschnick, Steven J. Schuldt, Jada B. Williams, Kevin Hallinan

Faculty Publications

Solar energy is a key renewable energy source; however, its intermittent nature and potential for use in distributed systems make power prediction an important aspect of grid integration. This research analyzed a variety of machine learning techniques to predict power output for horizontal solar panels using 14 months of data collected from 12 northern-hemisphere locations. We performed our data collection and analysis in the absence of irradiation data—an approach not commonly found in prior literature. Using latitude, month, hour, ambient temperature, pressure, humidity, wind speed, and cloud ceiling as independent variables, a distributed random forest regression algorithm modeled the combined …

Effectiveness Of China's Plug-In Electric Vehicle Subsidy, Tamara L. Sheldon, Rubal Dua

Faculty Publications

Subsidies for promoting plug-in electric vehicle (PEV) adoption are a key component of China's overall plan for reducing local air pollution and greenhouse gas emissions from the light-duty vehicle sector. In this paper, we explore the impact and cost-effectiveness of the Chinese PEV subsidy program. In particular, a vehicle choice model is estimated using a large random sample of individual level, model year 2017 Chinese new vehicle purchases. The choice model is then used to predict PEV market share under alternative policies. Simulation results suggest that the 2.5% PEV market share of Chinese new vehicle sales in 2017 resulted in …

Get Out And The Remediation Of Othello's Sunken Place: Beholding White Supremacy's Coagula, Vanessa I. Corredera

Faculty Publications

As a result of director and writer Jordan Peele's remediation of the horror genre to create a racially polemic film, breakout horror-thriller Get Out (2017) has achieved critical and commercial success while substantially affecting how Americans think about and approach race. As stories about a black man amidst an all-white community who ultimately strangles his white female lover, Get Out and Shakespeare's Othello share obvious narrative overlaps. Othello, however, maintains a more tenuous status regarding race and its function within the storyline than does Get Out. Othello remains a play mired in questions about how or even whether …

Family Structure And Child Well-Being In A Non-Western Context: The Role Of Parent–Child Relations And Parental Conflict In South Korea, Jonathan A. Jarvis, Ashley Larsen Gibby, Mikaela J. Dufur, Shana Pribesh

Faculty Publications

Research suggests that children who live with two biological married parents are less likely to exhibit behavioral problems than children who do not. While research on childhood outcomes often focuses on the nature of the family structure itself, recent studies have pointed to relationship quality between parents, and between parents and children, as important mechanisms through which family structure affects children. However, the independent influence of these two mechanisms—relationship quality between parents and between parents and children—on childhood outcomes has never, to our knowledge, been tested outside of a high-income western environment. Using the Korean Youth Panel Study (KYPS), we …

Hegel’S Pragmatism, Willem A. Devries

Faculty Publications

This chapter examines Hegel’s complex relation to pragmatism. After a short review of the extant literature on their relation, deVries focuses on their shared rejection of the Cartesian tradition, which assumes that minds are immaterial, self-contained substances that are (1) transparent to themselves, (2) known directly or immediately to themselves, (3) prior to and independently of any knowledge of any other created substance, e.g., the external world. Hegel and the pragmatists rejected this view for at least three reasons. (1) The Cartesians employ an impoverished conception of experience that does not do justice to the complex interplay of the sensory …

Tumor Necrosis Factor-Alpha Signaling May Contribute To Chronic West Nile Virus Post-Infectious Proinflammatory State, A. Arturo Leis, Marie F. Grill, Brent P. Goodman, Syed B. Sadiq, David J. Sinclair, Parminder J.S. Vig, Fengwei Bai

Faculty Publications

Background: West Nile virus (WNV) causes a spectrum of human disease ranging from a febrile illness (WNV fever) to severe neuroinvasive disease (meningitis, encephalitis, acute flaccid paralysis). Since WNV gained entry into North America in 1999, clinicians caring for WNV survivors have observed persistent neurological symptoms occurring long-after the production of neutralizing antibodies and clearance of the virus. Accordingly, alternative pathogeneses other than direct viral invasion have been hypothesized to explain these post-infectious symptoms. The dominant hypothesis is that antiviral inflammatory responses triggered initially to clear WNV may persist to promote a post-infectious proinflammatory state.

Methods: In 4 serologically-confirmed …

A Game-Theoretic Approach To Deciphering The Dynamics Of Amyloid-Beta Aggregation Along Competing Pathways, Preetam Ghosh, Pratip Rana, Vijayaraghavan Rangachari, Jhinuk Saha, Edward Steen, Ashwin Vaidya

Faculty Publications

Aggregation of amyloid-β (Aβ) peptides is a significant event that underpins Alzheimer's disease (AD). Aβ aggregates, especially the low-molecular weight oligomers, are the primary toxic agents in AD pathogenesis. Therefore, there is increasing interest in understanding their formation and behaviour. In this paper, we use our previously established results on heterotypic interactions between Aβ and fatty acids (FAs) to investigate off-pathway aggregation under the control of FA concentrations to develop a mathematical framework that captures the mechanism. Our framework to define and simulate the competing on- and off-pathways of Aβ aggregation is based on the principles of game theory. Together …

Faculty Publications

The red snapper Lutjanus campechanus is an exploited reef fish of major economic importance in the Gulf of Mexico region. Studies of genome wide genetic variation are needed to understand the structure of wild populations and develop breeding programs for aquaculture but interpretation of these genome scans is limited by the absence of reference genome. In this work, the first draft of a reference genome was developed and characterized for the red snapper. P-454 and Illumina sequencing were conducted to produce paired-end reads that were assembled into reference contigs and scaffolds. The current assembly spans over 770 Mb, representing an …

The thermodynamic equilibrium and kinetics of dissolution reactions are key to determining the rate at which oxides dissolve. The increase in collaborative research across disciplines in materials research necessitates a common background to tackle shared scientific problems across different fields. This review selectively examines the fundamentals of dissolution theories that have been developed in chemistry, geochemistry, and …

Host Induced Gene Silencing Targeting Aspergillus Flavus Aflm Reduced Aflatoxin Contamination In Transgenic Maize Under Field Conditions, Yenjit Raruang, Olanike Omolehin, Dongfang Hu, Qijian Wei, Zhu Qiang Han, Kanniah Rajasekaran, Jeffrey W. Cary, Kan Wang, Zhi Yuan Chen

Faculty Publications

Maize (Zea mays L.) is one of the major crops susceptible to Aspergillus flavus infection and subsequent contamination with aflatoxins, the most potent naturally produced carcinogenic secondary metabolites. This pathogen can pose serious health concerns and cause severe economic losses due to the Food and Drug Administration (FDA) regulations on permissible levels of aflatoxins in food and feed. Although biocontrol has yielded some successes in managing aflatoxin contamination, enhancing crop resistance is still the preferred choice of management for long-term sustainability. Hence, host induced gene silencing (HIGS) strategy was explored in this study. The A. flavus gene aflM encoding versicolorin …

Escherichia Coli Antimicrobial Resistance Variability In Water Runoff And Soil From A Remnant Native Prairie, And Improved Pasture, And A Cultivated Agricultural Watershed, Maitreyee Mukherjee, Terry Gentry, Heidi Mjelde, John P. Brooks, Daren Harmel, Lucas Gregory, Kevin Wagner

Faculty Publications

Although many previous studies have examined patterns of antimicrobial resistance (AMR) and multidrug resistance (MDR) from domestic animals and farm environments, comparatively little is known about the environmental sources and natural reservoirs of AMR and MDR. In this study, we collected stormwater runoff and soil samples from three watersheds in Texas. Escherichia coli (E. coli) were enumerated, isolated, and analyzed for resistance patterns. E. coli from all sites, irrespective of land use, displayed the presence of AMR/MDR. Higher levels of AMR/MDR were observed in water compared to soil. More isolates were resistant to cephalothin than other antibiotics. For …
