Genome-Wide Association Study Identified Candidate Genes For Alkalinity Tolerance In Rice, Lovepreet Singh, Rajat Pruthi, Sandeep Chapagain, Prasanta K. Subudhi Jun 2023

Genome-Wide Association Study Identified Candidate Genes For Alkalinity Tolerance In Rice, Lovepreet Singh, Rajat Pruthi, Sandeep Chapagain, Prasanta K. Subudhi

Faculty Publications

Alkalinity stress is a major hindrance to enhancing rice production globally due to its damaging effect on plants’ growth and development compared with salinity stress. However, understanding of the physiological and molecular mechanisms of alkalinity tolerance is limited. Therefore, a panel of indica and japonica rice genotypes was evaluated for alkalinity tolerance at the seedling stage in a genome-wide association study to identify tolerant genotypes and candidate genes. Principal component analysis revealed that traits such as alkalinity tolerance score, shoot dry weight, and shoot fresh weight had the highest contribution to variations in tolerance, while shoot Na+ concentration, shoot Na+:K+ …

A Comparison Of Bat Calls Recorded By Two Acoustic Monitors, Jane M. Kunberger, Ashley M. Long Jun 2023

A Comparison Of Bat Calls Recorded By Two Acoustic Monitors, Jane M. Kunberger, Ashley M. Long

Faculty Publications

Recent advances in low-cost autonomous recording unit (ARU) technology have made large-scale bat monitoring projects more practical, but several key features of ARUs (e.g., microphone quality and triggering thresholds) can influence their ability to detect and record bats. As such, it is important to quantify and report variation in ARU performance as new recording systems become available. We used the automated classification software SonoBat to compare the numbers of call files, echolocation pulses, and species recorded by a commonly used, full-spectrum bat detector-the Song Meter SM4BAT-FS-and a less expensive, open-source ARU that can detect ultrasound-the AudioMoth. We deployed paired ARUs …

Population and Public Health Science Faculty Publications

Background: Behavioral digital health interventions (e.g., mobile apps, websites, wearables) have been applied widely to improve health outcomes. However, many groups (e.g., people with low income levels, people who are geographically isolated, older adults) may face obstacles to technology access and use. In addition, research has found that biases and stereotypes can be embedded within digital health interventions. As such, behavioral digital health interventions that intend to improve overall population health may unintentionally widen health-related inequities. Purpose: This commentary offers guidance and strategies to mitigate these risks when using technology as a means for delivering a behavioral health intervention. Methods: …

Demystifying Longitudinal Data Analyses Using Structural Equation Models In School Psychology, Garret J. Hall, Kelly N. Clark Jun 2023

Demystifying Longitudinal Data Analyses Using Structural Equation Models In School Psychology, Garret J. Hall, Kelly N. Clark

Faculty Publications

Structural equation models (SEM) are a method of latent variable analysis that offer a high degree of flexibility in terms of modeling methods for applied research questions. Recent advancements associated with longitudinal SEM have unlocked innovative ways to decompose variance and to estimate mean trends over time (e.g., Allison et al., 2017; Berry & Willoughby, 2017; Hamaker et al., 2015; McArdle & Nesselroade, 2014). However, these longitudinal methods are not necessarily readily accessible to scholars seeking to advance theory and practice in school psychology. Importantly, not all longitudinal data are the same and not all longitudinal SEMs are the same; …

The biological age of the brain differs from its chronological age (CA) and can be used as biomarker of neural/cognitive disease processes and as predictor of mortality. Brain age (BA) is often estimated from magnetic resonance images (MRIs) using machine learning (ML) that rarely indicates how regional brain features contribute to BA. Leveraging an aggregate training sample of 3 418 healthy controls (HCs), we describe a ridge regression model that quantifies each region’s contribution to BA. After model testing on an independent sample of 651 HCs, we compute the coefficient of partial determination R̄2p for each regional brain volume to …

Exploring The Experiences Of Pregnant Women In The U.S. During The First Year Of The Covid-19 Pandemic, Courtney E. Williams, Dana Berkowitz, Heather M. Rackin

Faculty Publications

In this paper, we integrate the stress process model with symbolic interactionism to frame our analysis of interviews with 35 women who were pregnant and/or gave birth during the first year of the Covid-19 pandemic. We detail three stressors, highlight their variation, and discuss how they coped with these stressors. Women reported having to navigate contradictory information about the public health crisis, but Black participants simultaneously endured added strain from a heightened awareness of racialized violence. To cope with an overabundance of precarious and contradictory messages, some women sought out information (i.e., information gatherers), others eschewed information (i.e., information avoiders), …

Alkali-Silica Reaction Mitigation Using Alternative Supplementary Cementitious Materials, Craig Newtson, Judit M. Garcia, Seyedsaleh Mousavinezhad Jun 2023

Alkali-Silica Reaction Mitigation Using Alternative Supplementary Cementitious Materials, Craig Newtson, Judit M. Garcia, Seyedsaleh Mousavinezhad

Data

Over the past few decades, Class F fly ash has been widely used in concrete as a supplementary cementitious material (SCM) due, in part, to its ability to mitigate alkali-silica reaction (ASR). However, future availability of fly ash is uncertain as the energy industry shifts towards renewable sources, resulting in the closure of coal-burning power plants. Therefore, there is a growing need to find alternatives to fly ash that are both cost effective and environmentally friendly. This study aimed to evaluate the effectiveness of ground-granulated blast furnace slag (GGBFS), metakaolin, and a locally available natural pozzolan mined from a pumicite …

Accelerated Sulfate Attack Testing For Concrete, Craig Newtson, Seyedsaleh Mousavinezhad, William Toledo, Federico Aguayo

Data

Extensive research has been conducted on sulfate attack of concrete structures, however, the need to adopt use of more sustainable materials is driving a need for a quicker test method to assess sulfate resistance. Class F fly ash, which is a byproduct of coal combustion for electricity generation, has historically been used in concrete mixtures to improve sulfate resistance. However, environmental considerations and evolving energy industry has decreased its availability, requiring the identification of economically viable and environmentally friendly alternatives to fly ash. Another challenge in addressing sulfate attack durability issues in concrete is that the standard sulfate attack test …

A Kronecker Limit Formula For Indefinite Zeta Functions, Gene S. Kopp Jun 2023

A Kronecker Limit Formula For Indefinite Zeta Functions, Gene S. Kopp

Faculty Publications

We prove an analogue of Kronecker’s second limit formula for a continuous family of “indefinite zeta functions”. Indefinite zeta functions were introduced in the author’s previous paper as Mellin transforms of indefinite theta functions, as defined by Zwegers. Our formula is valid in dimension g= 2 at s= 1 or s= 0 . For a choice of parameters obeying a certain symmetry, an indefinite zeta function is a differenced ray class zeta function of a real quadratic field, and its special value at s= 0 was conjectured by Stark to be a logarithm of an algebraic unit. Our formula also …

Wedge Domains In Compactly Causal Symmetric Spaces, Karl Hermann Neeb, Gestur Ólafsson Jun 2023

Wedge Domains In Compactly Causal Symmetric Spaces, Karl Hermann Neeb, Gestur Ólafsson

Faculty Publications

Motivated by constructions in Algebraic Quantum Field Theory we introduce wedge domains in compactly causal symmetric spaces M = G/H, which includes in particular anti-de Sitter space in all dimensions and its coverings. Our wedge domains generalize Rindler wedges in Minkowski space. The key geometric structure we use is the modular flow on M defined by an Euler element in the Lie algebra of G. Our main geometric result asserts that three seemingly different characterizations of these domains coincide: the positivity domain of the modular vector field, the domain specified by a KMS-like analytic extension condition for the modular flow, …

Quantum Fluctuations Spatial Mode Profiler, Charris Gabaldon, Pratik Barge, Savannah L. Cuozzo, Irina Novikova, Hwang Lee, Lior Cohen, Eugeniy E. Mikhailov

Faculty Publications

The spatial mode is an essential component of an electromagnetic field description, yet it is challenging to characterize it for optical fields with the low average photon number, such as in a squeezed vacuum. We present a method for the reconstruction of the spatial modes of such fields based on the homodyne measurements of their quadrature noise variance performed with a set of structured masks. We show theoretically that under certain conditions, we can recover individual spatial mode distributions by using the weighted sum of the basis masks, where weights are determined using measured variance values and phases. We apply …

Near-threshold resonances play an important role in nucleosynthesis and applied nuclear science. The study of nuclei removed from stability has greatly extended the list of resonances close to decay thresholds. The no core shell model with continuum (NCSMC) recently predicted an s-wave resonance just above the proton-decay threshold of Li7 at an excitation energy of 10.2 MeV. This potential case of a near-threshold resonance is dependent on the quantum mechanics of the p+He6 fragments extended into the continuum. The He6(d,n)Li∗7 reaction was employed in an attempt to populate this resonance and search for its proton decay via the invariant-mass method. …

The Aegean-169 Clade Of Bacterioplankton Is Synonymous With Sar11 Subclade V (Himb59) And Metabolically Distinct, Eric W. Getz, V. Celeste Lanclos, Conner Y. Kojima, Chuankai Cheng, Michael W. Henson, Max Emil Schön, Thijs J.G. Ettema, Brant C. Faircloth, J. Cameron Thrash

Faculty Publications

Bacterioplankton of the SAR11 clade are the most abundant marine microorganisms and consist of numerous subclades spanning order-level divergence (Pelagibacterales). The assignment of the earliest diverging subclade V (a.k.a. HIMB59) to the Pelagibacterales is highly controversial, with multiple recent phylogenetic studies placing them completely separate from SAR11. Other than through phylogenomics, subclade V has not received detailed examination due to limited genomes from this group. Here, we assessed the ecogenomic characteristics of subclade V to better understand the role of this group in comparison to the Pelagibacterales. We used a new isolate genome, recently released single-amplified genomes and metagenome-assembled genomes, …

Faculty Publications

The introduction of electron-withdrawing groups on 8(meso)-pyridyl-BODIPYs tends to increase the fluorescence quantum yields of this type of compound due to the decrease in electronic charge density on the BODIPY core. A new series of 8(meso)-pyridyl-BODIPYs bearing a 2-, 3-, or 4-pyridyl group was synthesized and functionalized with nitro and chlorine groups at the 2,6-positions. The 2,6-methoxycarbonyl-8-pyridyl-BODIPYs analogs were also synthesized by condensation of 2,4-dimethyl-3-methoxycarbonyl-pyrrole with 2-, 3-, or 4-formylpyridine followed by oxidation and boron complexation. The structures and spectroscopic properties of the new series of 8(meso)-pyridyl-BODIPYs were investigated both experimentally and computationally. The BODIPYs bearing 2,6-methoxycarbonyl groups showed enhanced …

Gluten-free bread is an important product that is under development using different sources, such as rice and starchy plants. Teosinte seeds are utilized by ethnic groups in Honduras to produce gluten-free flour to prepare traditional baked goods and beverages. The quality of gluten-free products could vary depending on flour properties, such as amylose content, particle size, and water absorption capacity. A good strategy for developing baked goods is to mix different cereal grain sources to optimize their physicochemical properties.
