A Divide-And-Conquer Approach For Genomic Prediction In Rubber Tree Using Machine Learning, Alexandre Hild Aono, Felipe Roberto Francisco, Livia Moura Souza, Paulo De Souza Gonçalves, Erivaldo J. Scaloppi Junior, Vincent Le Guen, Roberto Fritsche-Neto, Gregor Gorjanc, Marcos Gonçalves Quiles, Anete Pereira De Souza

Faculty Publications

Rubber tree (Hevea brasiliensis) is the main feedstock for commercial rubber; however, its long vegetative cycle has hindered the development of more productive varieties via breeding programs. With the availability of H. brasiliensis genomic data, several linkage maps with associated quantitative trait loci have been constructed and suggested as a tool for marker-assisted selection. Nonetheless, novel genomic strategies are still needed, and genomic selection (GS) may facilitate rubber tree breeding programs aimed at reducing the required cycles for performance assessment. Even though such a methodology has already been shown to be a promising tool for rubber tree breeding, increased model …

Epidemic Time Series Similarity Is Related To Geographic Distance And Age Structure, Tad Dallas, Grant Foster, Robert L. Richards, Bret D. Elderd

Faculty Publications

Objective

More similar locations may have similar infectious disease dynamics. There is clear overlap in putative causes for epidemic similarity, such as geographic distance, age structure, and population size. We compare the effects of these potential drivers on epidemic similarity compared to a baseline assumption that differences in the basic reproductive number (R₀) will translate to differences in epidemic trajectories.

Methods

Using COVID-19 case counts from United States counties, we explore the importance of geographic distance, population size differences, and age structure dissimilarity on resulting epidemic similarity.

Results

We find clear effects of geographic space, age structure, …

Infectious diarrhea is a major cause of infant mortality in most developing countries. In this research, we evaluated the potential of immobilized Lactobacillus plantarum NCIMB 8826 on weanimix infant cereal and its effectiveness in reducing the severity of Citrobacter rodentium-induced diarrhea in weanling mice. Thirty-six C57BL/6 weanling mice were placed into four groups (n = 9 each; negative, positive, prevention and cure). Mice received either L. plantarum (109 CFU/g) immobilized on weanimix infant cereal 3 days before C. rodentium (109 CFU/ ml) infection (Prevention) or 3 days after C. rodentium infection (Cure). A positive control group was infected with C. …

A Leray Model For The Orlik–Solomon Algebra, Christin Bibby, Graham Denham, Eva Maria Feichtner

Faculty Publications

We construct a combinatorial generalization of the Leray models for hyperplane arrangement complements. Given a matroid and some combinatorial blow-up data, we give a presentation for a bigraded (commutative) differential graded algebra. If the matroid is realizable over C, this is the familiar Morgan model for a hyperplane arrangement complement, embedded in a blowup of projective space. In general, we obtain a CDGA that interpolates between the Chow ring of a matroid and the Orlik–Solomon algebra. Our construction can also be expressed in terms of sheaves on combinatorial blowups of geometric lattices. As a key technical device, we construct a …

Reference Database Of Teeth Images From The Family Bovidae, Juliet K. Brophy, Gregory J. Matthews

Faculty Publications

Researchers typically rely on fossils from the Family Bovidae to generate African paleoenvironmental reconstructions due to their strict ecological tendencies. Bovids have dominated the southern African fauna for the past four million years and, therefore, dominate the fossil faunal assemblages, especially isolated teeth. Traditionally, researchers reference modern and fossil comparative collections to identify teeth. However, researchers are limited by the specific type and number of bovids at each institution. B.O.V.I.D. (Bovidae Occlusal Visual IDentification) is a repository of images of the occlusal surface of bovid teeth. The dataset currently includes extant bovids from 7 tribes and 20 species (~3900). B.O.V.I.D. …

Faculty Publications

A growing number of people in the United States seek to self-manage their abortions by self-sourcing abortion medications online. Prior research focuses on people's motivations for seeking self-management of abortion and experiences trying to obtain medications. However, little is known about the experiences of people in the U.S. who actually complete a self-managed abortion using medications they self-sourced online. We conducted anonymous in-depth interviews with 80 individuals who sought abortion medications through Aid Access, the only online telemedicine service that provides abortion medications in all 50 U.S. states. Through grounded theory analysis we identified five key themes: 1) participants viewed …

Covid-19 Vaccination In Africa: A Case Of Unsatisfied Expectation And Ill-Preparedness, Osmond C. Ekwebelem, Phemelo Tamasiga, Abullhai Tunde Abonde, Ismaeel Yunusa Ph. D., Uju Nwauzoma, Helen Onyeaka

Faculty Publications

With a population of 1.3 billion people, of which 56% reside in rural settings, Africa seemed ill-prepared to handle the distribution of a COVID-19 vaccine. In addition, the capacity needed for a successful COVID- 19 vaccination campaign in Africa surpassed the available resources in local and state health agencies. As a result, African governments were advised to coordinate resources, health officials, and vaccinators, including local health practitioners, medical technicians, and pharmacists for the largest-ever vaccination campaign in Africa. Although the rolling out of the SARS-COV-2 vaccine was, as expected, slow in many African countries, and not yet enough to cover …

Faculty Publications

The Three Rivers Solid Waste Authority (TRSWA) operates a MSW landfill outside Jackson, South Carolina (USA) at which leachate ammonia concentrations are of concern. The landfill operates a droplet spraying/misting system (known as the Lilypad system) in their pond to enhance both leachate evaporation and, possibly, ammonia volatilization. The overall goals of this study were to determine the fate of nitrogen in the pond and to ultimately quantify the role the Lilypad system plays in enhancing ammonia removal. To accomplish the study goals, an empirical model based on collected leachate and mist samples, climatological data, and pond hy-draulic data was …

Galla Placidia And The “Daughter Of The Queen Of The South”: The Historical Consequences Of A Late Roman Interpretation Of Daniel 11, Kenneth Atkinson

Faculty Publications

The tragic story of the Roman Empire’s decline and fall has captivated the imaginations of countless artists, scholars, and filmmakers, among others. The many rulers of the Roman Empire—regardless of whether they were competent or not to hold office—dealt with insurmountable problems such as frequent invasions, numerous civil wars, attempted coups, unchecked immigration, racism, economic downturns, inept government officials, political corruption, changing values, religious violence, and sexism. Yet, despite overwhelming odds, the Roman Empire managed to survive these and other threats until September of 476 A.D. when a Roman of Gothic origin, Odoacer, forced the emperor Romulus Augustulus, to abdicate. …

The Effect Of The Inclusion Of Trunk-Strengthening Exercises To A Multimodal Exercise Program On Physical Activity Levels And Psychological Functioning In Older Adults: Secondary Data Analysis Of A Randomized Controlled Trial, Behnaz Shahtahmassebi, Jacinta Hatton, Jeffrey J. Hebert, Mark Hecimovich, Helen Correia, Timothy J. Fairchild

Faculty Publications

Background: Engaging in multimodal exercise program helps mitigate age-related decrements by improving muscle size, muscle strength, balance, and physical function. The addition of trunk-strengthening within the exercise program has been shown to significantly improve physical functioning outcomes. Whether these improvements result in improved psychological outcomes associated with increased physical activity levels requires further investigation. We sought to explore whether the inclusion of trunk-strengthening exercises to a multimodal exercise program improves objectively measured physical activity levels and self-reported psychological functioning in older adults. Method: We conducted a secondary analysis within a single-blinded parallel-group randomized controlled trial. Sixty-four healthy older (≥ 60 …

A Paleo-Perspective On West Antarctic Ice Sheet Retreat, Philip J. Bart, Matthew Kratochvil

Faculty Publications

Geological records of ice sheet collapse can provide perspective on the ongoing retreat of grounded and floating ice. An abrupt retreat of the West Antarctic Ice Sheet (WAIS) that occurred during the early deglaciation is well recorded on the eastern Ross Sea continental shelf. There, an ice shelf breakup at 12.3 ± 0.6 cal. (calibrated) kyr BP caused accelerated ice-mass loss from the Bindschadler Ice Stream (BIS). The accelerated mass loss led to a significant negative mass balance that re-organized WAIS flow across the central and eastern Ross Sea. By ~ 11.5 ± 0.3 cal kyr BP, dynamic thinning of …

We sought to estimate the association between maternal exposure to O₃ and term birth weight and term small for gestational age (SGA) in the United States (US).

Methods: We conducted a nationwide study including 2,179,040 live term singleton births that occurred across 453 populous counties in the contiguous US in 2002. Daily county-level concentrations of O₃ data were estimated using a Bayesian fusion model. We used linear regression to estimate the association between O_{3 …}

Dual Nature Of Magnetic Nanoparticle Dispersions Enables Control Over Short-Range Attraction And Long-Range Repulsion Interactions, Ahmed Al Harraq, Aubry A. Hymel, Emily Lin, Thomas M. Truskett, Bhuvnesh Bharti

Faculty Publications

Competition between attractive and repulsive interactions drives the formation of complex phases in colloidal suspensions. A major experimental challenge lies in decoupling independent roles of attractive and repulsive forces in governing the equilibrium morphology and long-range spatial distribution of assemblies. Here, we uncover the ‘dual nature’ of magnetic nanoparticle dispersions, particulate and continuous, enabling control of the short-range attraction and long-range repulsion (SALR) between suspended microparticles. We show that non-magnetic microparticles suspended in an aqueous magnetic nanoparticle dispersion simultaneously experience a short-range depletion attraction due to the particulate nature of the fluid in competition with an in situ tunable long-range …

Faculty Publications

This paper presents an extensive review of existing techniques used in estimating design wind pressures considering Reynolds number and turbulence effects, as well as a case study of a reference building investigated experimentally. We shed light on the limitations of current aerodynamic testing techniques, provisions in design standards, and computational fluid dynamics (CFD) methods to predict wind-induced pressures. The paper highlights the reasons for obstructing the standardization of the wind tunnel method. Moreover, we introduce improved experimental and CFD techniques to tackle the identified challenges. CFD provides superior and efficient performance by employing wall-modeled large-eddy simulation (WMLES) and hybrid RANS-LES …

Patterns And Predictors Of Adherence To Breast Cancer Screening Recommendations In Alberta's Tomorrow Project, Olivia K. Loewen, Navjot Sandila, Grace Shen-Tu, Jennifer E. Vena, Huiming Yang, Kara Patterson, Jian Yi Xu

Faculty Publications

Breast cancer screening is an important prevention component as it can reduce cancer mortality and improve survival. Understanding patterns of adherence to screening recommendations is essential to guide health promotion strategies and policy implementation efforts. The 1999 Alberta screening guidelines were used to determine screening status for eligible female participants in Alberta's Tomorrow Project (n = 4,972), a longitudinal province-based cohort. Screening patterns were derived based on screening status assessed at enrollment (2001–2008) and follow-up (2008–2011). Information on reason for screening was also collected at each time point. Multinomial logistic regression was used to assess potential predictors of adherence to …

Personalized Breast Cancer Onset Prediction From Lifestyle And Health History Information, Shi Ang Qi, Neeraj Kumar, Jian Yi Xu, Jaykumar Patel, Sambasivarao Damaraju, Grace Shen-Tu, Russell Greiner

Faculty Publications

We propose a method to predict when a woman will develop breast cancer (BCa) from her lifestyle and health history features. To address this objective, we use data from the Alberta's Tomorrow Project of 18,288 women to train Individual Survival Distribution (ISD) models to predict an individual's Breast-Cancer-Onset (BCaO) probability curve. We show that our three-step approach-(1) filling missing data with multiple imputations by chained equations, followed by (2) feature selection with the multivariate Cox method, and finally, (3) using MTLR to learn an ISD model-produced the model with the smallest L1-Hinge loss among all calibrated models with comparable C-index. …

A Systematic Literature Review Of Anti-Discrimination Design Strategies In The Digital Sharing Economy, Miroslav Tushev, Fahimeh Ebrahimi, Anas Mahmoud

Faculty Publications

Applications of the Digital Sharing Economy (DSE), such as Uber, Airbnb, and TaskRabbit, have become a main facilitator of economic growth and shared prosperity in modern-day societies. However, recent research has revealed that the participation of minority groups in DSE activities is often hindered by different forms of bias and discrimination. Evidence of such behavior has been documented across almost all domains of DSE, including ridesharing, lodging, and freelancing. However, little is known about the underlying design decisions of DSE platforms which allow certain demographics of the market to gain unfair advantage over others. To bridge this knowledge gap, in …

Faculty Publications

Anthracnose caused by Colletotrichum gloeosporioides is a major postharvest disease that reduces the shelf life of mango (Mangifera indica L. cv. Nam Dokmai), an indigenous crop of Thailand. Curcumin, a substance in turmeric, has antimicrobial activity, which is hypothesized to be enhanced in the form of nanoparticles. In this research, curcumin-loaded zein nanoparticles (CZNP) were synthesized using a liquid-liquid dispersion method and were incorporated into zein coating material. The effect against C. gloeosporioides was evaluated relative to curcumin and zein mixture solution (CZ) as a control. The results showed that the solution of free curcumin at 100 μg/ml (CZ100) was …

Analytical Modification Of Edfm For Transient Flow In Tight Rocks, Olufemi Olorode, Harun Rashid

Faculty Publications

The commercial development of unconventional resources with multiply fractured horizontal wells has been in the spotlight over the last ten years because of the significant contribution of unconventional oil and gas (UOG) reservoirs to the total US oil and gas production. UOG reservoirs contain multiscale fractures with heterogeneous properties, so the focus has been on efficient and accurate models that can account for these fractures individually. One of such models is the embedded discrete fracture model (EDFM), which has been applied to various types of fractured reservoirs. This work shows that the application of EDFM in fractured tight rocks yields …

A Statistical Analysis Of Sporadic-E Characteristics Associated With Gnss Radio Occultation Phase And Amplitude Scintillations, Daniel J. Emmons, Dong L. Wu, Nimalan Swarnalingam

Faculty Publications

Statistical GNSS-RO measurements of phase and amplitude scintillation are analyzed at the mid-latitudes in the local summer for a 100 km altitude. These conditions are known to contain frequent sporadic-E, and the S4-σ_ϕ trends provide insight into the statistical distributions of the sporadic-E parameters. Joint two-dimensional S4-σ_ϕ histograms are presented, showing roughly linear trends until the S4 saturates near 0.8. To interpret the measurements and understand the sporadic-E contributions, 10,000 simulations of RO signals perturbed by sporadic-E layers are performed using length, intensity, and vertical thickness distributions from previous studies, with the assumption that the sporadic-E layer acts …

What was it like to have come of age after the Glorious Thirty (1945-1975), an era Jack Metzger (2016; 2021a) describes as a time when the working-class bettered their lives? I had the misfortune to have worked in several Metropolitan Detroit factories during the period of decline after the Glorious Thirty. During that time, I witnessed what the journalist George Packer (2013) has called ‘the Unwinding,’ the unraveling of the social contract that has left the working class to their own devices to find success and salvation. In keeping with the tradition in working-class studies of sharing lived experienced of …

Periodization At Qumran And Its Importance For Understanding Hellenistic History, Kenneth Atkinson

Faculty Publications

Periodization, the belief that God has divided history into fixed segments of time, frequently appears in Second Temple Period Jewish literature. It is especially popular in the Qumran texts, whose authors often display an interest in apocalyptic historiography to explain and categorize historical occurrences. The writers of the Dead Sea Scrolls frequently use periodization to uncover and comprehend historical events. These writings often couple this doctrine with apocalyptic eschatology, specifically the use of Scripture to organize history into discrete historical periods to calculate the end of days. The present study briefly highlights periodization in the Dead Sea Scrolls in light …
