The epoch of the Anthropocene, a period during which human activity has been the dominant influence on climate and the environment, has witnessed a decline in oxygen concentrations and an expansion of oxygen-depleted environments in both coastal and open ocean systems since the middle of the 20th century. This paper provides a review of system-specific drivers of low oxygen in a range of case studies representing marine systems in the open ocean, on continental shelves, in enclosed seas and in the coastal environment. Identification of similar and contrasting responses within and across system types and corresponding oxygen regimes is shown …

Benthic Nutrient Fluxes Across Subtidal And Intertidal Habitats In Breton Sound In Response To River-Pulses Of A Diversion In Mississippi River Delta, Robert R. Twilley, Silke Rick, Daniel C. Bond, Justin Baker Sep 2021

Benthic Nutrient Fluxes Across Subtidal And Intertidal Habitats In Breton Sound In Response To River-Pulses Of A Diversion In Mississippi River Delta, Robert R. Twilley, Silke Rick, Daniel C. Bond, Justin Baker

Faculty Publications

We measured benthic fluxes of dissolved nutrients in subtidal sediments and intertidal soils associated with river-pulse events from Mississippi River via the operation of a river diversion struc-ture at Caernarvon, LA. Experiments measuring benthic fluxes in subtidal habitats were conducted during the early spring flood pulse (February and March) each year from 2002 to 2004, compared to benthic fluxes of intertidal habitats measured in February and March 2004. Nitrate (NO3−) uptake rates for subtidal sediments and intertidal soils depended on overlying water NO3− concentrations at near-, mid-, and far-field locations during river-pulse experiments when water temperatures were …

Biogeochemical And Hydrological Variables Synergistically Influence Nitrate Variability In Coastal Deltaic Wetlands, Alicia Sendrowski, Edward Castañeda-Moya, Robert Twilley, Paola Passalacqua Sep 2021

Biogeochemical And Hydrological Variables Synergistically Influence Nitrate Variability In Coastal Deltaic Wetlands, Alicia Sendrowski, Edward Castañeda-Moya, Robert Twilley, Paola Passalacqua

Faculty Publications

Coastal river deltas are centers of surface water nitrate processing, yet the mechanisms controlling spatio-temporal patterns in nutrient variability are still little understood. Nitrate fluctuations in these systems are controlled by complex interactions between hydrological and biogeochemical drivers, which act together to transport and transform inorganic nutrients. Distinguishing the contributions of these drivers and identifying wetland zones where nitrate processing is occurring can be difficult, yet is critical to make assessments of nutrient removal capacity in deltaic wetlands. To address these issues, we analyze relationships among regional “external” (river discharge, tides, wind) and local “internal” (water level, temperature, turbidity, and …

An Integrated Energy Simulation Model Of A Compressed Air System For Sustainable Manufacturing: A Time‐Discretized Approach, Vansh Vyas, Hyun Woo Jeon, Chao Wang Sep 2021

An Integrated Energy Simulation Model Of A Compressed Air System For Sustainable Manufacturing: A Time‐Discretized Approach, Vansh Vyas, Hyun Woo Jeon, Chao Wang

Faculty Publications

A compressed air system (CAS) is one of the most common and energy‐consuming systems in manufacturing. To practice more economically and environmentally sustainable manufacturing, manufacturers need ways to reduce the energy costs and carbon footprint, resulting from a CAS in their production systems. While preliminary energy studies on a CAS and on machining processes are available separately, existing research studies rarely analyze energy costs using a tool that considers both a CAS and production systems. Therefore, in this study, we propose an energy simulation tool that combines a CAS and a production system to evaluate the effects of a CAS …

An Extended Essay On Church Autonomy, Carl H. Esbeck Sep 2021

An Extended Essay On Church Autonomy, Carl H. Esbeck

Faculty Publications

The doctrine of church autonomy has its own exclusive line of precedent running from Watson v. Jones (1872) through Kedroff v. St. Nicholas Cathedral (1952) - where the doctrine was first recognized as having First Amendment stature - and culminating with renewed vigor for religious institutional autonomy in the unanimous decision of Hosanna-Tabor Evangelical Lutheran Church and School v. EEOC (2012). Attention to church autonomy has expanded rapidly since the Supreme Court’s decision in Hosanna-Tabor, and its scope is much disputed as it pushes aside other claims and interests. In its most familiar form—the “ministerial exception” - it is …

Faculty Publications

Background: In-season competition and tournaments for team sports can be both long and congested, with some sports competing up to three times per week. During these periods of time, athletes need to prepare technically, tactically and physically for the next fixture and the short duration between fixtures means that, in some cases, physical preparation ceases, or training focus moves to recovery as opposed to progressing adaptations. Objective: The aim of this review was to investigate the effect of training frequency on muscular strength to determine if a potential method to accommodate in-season resistance training, during busy training schedules, could be …

Ruth Bader Ginsburg's Intellectual Property Jurisprudence, Ryan Vacca, Ann Bartow

Faculty Publications

On September 18, 2020, the world lost an irreplaceable leader. Justice Ruth Bader Ginsburg, after many years of battling cancer, had passed away. Although she will primarily be remembered for her work on gender equality—as both advocate and jurist—Justice Ginsburg signiicantly impacted other areas of the law. One such area is intellectual property. During her time on the U.S. Supreme Court, she authored 20 opinions in these areas—11 copyright, seven patent, and two trademark—and joined the opinions of her colleagues in many others.

We report the discovery of KMT-2020-BLG-0414Lb, with a planet-to-host mass ratio q2 = 0:9- 1:2 × 10-5 = 3-4 q⊕ at 1σ, which is the lowest mass-ratio microlensing planet to date. Together with two other recent discoveries (4. q=q⊕. 6), it fills out the previous empty sector at the bottom of the triangular (log s; log q) diagram, where s is the planet-host separation in units of the angular Einstein radius θE. Hence, these discoveries call into question the existence, or at least the strength, of the break in the mass-ratio function that was previously suggested to account for the …

Several bird taxa have been recently described or elevated to full species and almost twice as many bird species than are currently recognized may exist. Defining species is one of the most basic and important issues in biological science because unknown or poorly defined species hamper subsequent studies. Here, we evaluate the species limits and evolutionary history of Tunchiornis ochraceiceps-a widespread forest songbird that occurs in the lowlands of Central America, Choco and Amazonia-using an integrative approach that includes plumage coloration, morphometrics, vocalization and genomic data. The species has a relatively old crown age (similar to 9 Ma) and comprises …

The rapid and widespread evolution of fungicide resistance remains a challenge for crop disease management. The demethylation inhibitor (DMI) class of fungicides is a widely used chemistry for managing disease, but there has been a gradual decline in efficacy in many crop pathosystems. Reliance on DMI fungicides has increased resistance in populations of the plant pathogenic fungus Cercospora beticola worldwide. To better understand the genetic and evolutionary basis for DMI resistance in C. beticola, a genome-wide association study (GWAS) and selective sweep analysis were conducted for the first time in this species. We performed whole-genome resequencing of 190 C. beticola …

Paula-Moraes, Ronald C. Stephenson, Christopher A. Wheeler, Earl Eugene Ringpis, Tyler S. Crum, J. Khai Tran

Faculty Publications

Novel strategies for the management of soybean looper, Chrysodeixis includens (Walker) (Lepidoptera: Noctuidae), are needed due to its increasing importance, costs, and challenges of management in soybeans (Glycine max [L.] Merr.; Fabaceae) in the Americas. Pheromone-mediated mating disruption may be 1 such novel strategy, but an effective tool for estimating mating disruption success must be found. The technique of trapping male moths using pheromone baited traps is a common method for assessing mating disruption technology. This paper reports on the testing of 2 trap types and 3 commercially available lures containing (Z)-7-dodecenyl acetate as the major active component. Trapping was …

Temporal Changes In Cuticular Hydrocarbons During Worker-Reproductive Transition In The Eastern Subterranean Termite (Blattodea: Rhinotermitidae), Qian Sun, Kenneth F. Haynes, Xuguo Zhou Sep 2021

Temporal Changes In Cuticular Hydrocarbons During Worker-Reproductive Transition In The Eastern Subterranean Termite (Blattodea: Rhinotermitidae), Qian Sun, Kenneth F. Haynes, Xuguo Zhou

Faculty Publications

In social insects, the reproductive division of labor is often regulated through communication using cuticular hydrocarbons (CHCs) that indicate caste identity and reproductive status. In many termites, workers retain reproductive potential and can differentiate into ergatoid reproductives, and this process is mediated by the presence of reproductives in sex- and age-specific patterns. However, little is known about the variation of CHCs profiles during this transition. In this study, we analyzed the CHC profiles of workers in comparison with ergatoids of different age, sex, and mating status in the eastern subterranean termite, Reticulitermes flavipes (Kollar) (Blattodea: Rhinotermitidae), one of the most …

Managing Corpses From Different Castes In The Eastern Subterranean Termite, Jizhe Shi, Chi Zhang, Sirui Huang, Austin Merchant, Qian Sun, Chuan Zhou, Kenneth F. Haynes, Xuguo Zhou

Faculty Publications

Corpse management is essential for social animals to maintain colony health. In the eastern subterranean termite, Reticulitermes flavipes, workers carry out undertaking behaviors to mitigate the risks associated with the dead. In this study, we hypothesized that termites would respond differently to the corpses from different castes based on their postmortem chemical signatures. To test this hypothesis, we 1) documented the behavioral responses of the workers toward corpses from different castes, and 2) profile the chemical signatures of these corpses. Corpses from all castes were retrieved inside the nests and cannibalized when they were decomposed <64 >h, regardless of the presence …

Biology, Ecology, And Pest Management Of The Tarnished Plant Bug, Lygus Lineolaris (Palisot De Beauvois) In Southern Row Crops, Justin George, James P. Glover, Jeffrey Gore, Whitney D. Crow, Gadi V.P. Reddy Sep 2021

Biology, Ecology, And Pest Management Of The Tarnished Plant Bug, Lygus Lineolaris (Palisot De Beauvois) In Southern Row Crops, Justin George, James P. Glover, Jeffrey Gore, Whitney D. Crow, Gadi V.P. Reddy

Faculty Publications

The tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), (Hemiptera: Miridae) is considered the most damaging pest of cotton (Gossypium hirsutum L.) in the mid-southern United States, although it is established throughout the United States, southern Canada, and northern Mexico. The introduction of transgenic crops for the control of moths in the Heliothine complex and eradication of the boll weevil, Anthonomus grandis, from much of the United States led to greatly reduced pesticide use in cotton fields, which allowed L. lineolaris to emerge as a new primary pest of cotton in the mid-southern United States. Since the publication of a …

A Tale Of Two Representations: Energy And Time In Photoabsorption, A. R.P. Rau Sep 2021

A Tale Of Two Representations: Energy And Time In Photoabsorption, A. R.P. Rau

Faculty Publications

This essay is based on a talk at Advances in Atomic, Molecular, and Optical Sciences 2020 (AAMOS20) in a symposium honoring Prof. S. T. Manson's decades-long contribution to photoabsorption studies. Quantum physics introduced into physics pairs of conjugate quantities bearing a specific complementary relationship, energy and time being one such pair. This gives rise to two alternative representations, a time-dependent and a time-independent one, seemingly very different but both capable of embracing the same physics. They give complementary descriptions and insight, with technical questions, theoretical and experimental, determining which may be the more convenient and practicable at any juncture. Two …

Symmetries And Geometries Of Qubits, And Their Uses, A. R.P. Rau Sep 2021

Symmetries And Geometries Of Qubits, And Their Uses, A. R.P. Rau

Faculty Publications

The symmetry SU(2) and its geometric Bloch Sphere rendering have been successfully applied to the study of a single qubit (spin-1/2); however, the extension of such symmetries and geometries to multiple qubits—even just two—has been investigated far less, despite the centrality of such systems for quantum information processes. In the last two decades, two different ap-proaches, with independent starting points and motivations, have been combined for this purpose. One approach has been to develop the unitary time evolution of two or more qubits in order to study quantum correlations; by exploiting the relevant Lie algebras and, especially, sub-algebras of the …

Directly Determined Properties Of Hd 97658 From Interferometric Observations, Tyler G. Ellis, Tabetha Boyajian, Kaspar Von Braun, Roxanne Ligi, Denis Mourard, Diana Dragomir, Gail H. Schaefer, Christopher D. Farrington

Faculty Publications

We conducted interferometric observations with the CHARA Array of transiting super-Earth host HD 97658 and measured its limb-darkened angular diameter to be theta(LD) = 0.314 +/- 0.004 mas. The combination of the angular diameter with the Gaia EDR3 parallax value with zero-point correction (pi = 46.412 +/- 0.022 mas, d =21.546 +/- 0.011 pc) yields a physical radius of R-star = 0.728 +/- 0.008 R-circle dot. We also measured the bolometric flux of the star to be F-bol = 2.42 +/- 0.05 x 10(-8) erg s(-1) cm(-2), which, together with angular size, allows a measurement of the effective temperature T-eff …

Identifying Areas Of Overlap And Distinction In Early Lexical Profiles Of Children With Autism Spectrum Disorder, Late Talkers, And Typical Talkers, Eva Jiménez, Eileen Haebig, Thomas T. Hills

Faculty Publications

This study compares the lexical composition of 118 children with autism spectrum disorder (ASD) aged 12 to 84 months with 4626 vocabulary-matched typically developing toddlers with and without language delay, aged 8 to 30 months. Children with ASD and late talkers showed a weaker noun bias. Additionally, differences were identified in the proportion of nouns and verbs, and in the semantic categories of animals, toys, household items and vehicles. Most differences appear to reflect the extent of the age differences between the groups. However, children with ASD produced fewer high-social verbs than typical talkers and late talkers, a difference that …

A 3d Printed Vitrification Device For Storage In Cryopreservation Vials, Yue Liu, Andy Lin, Terrence R. Tiersch, William Todd Monroe Sep 2021

A 3d Printed Vitrification Device For Storage In Cryopreservation Vials, Yue Liu, Andy Lin, Terrence R. Tiersch, William Todd Monroe

Faculty Publications

Sperm cryopreservation by vitrification is a promising approach for small-bodied animals such as zebrafish (Danio rerio). However, most vitrification tools adopted in aquatic research were initially designed for applications other than sperm (such as human embryo freezing) and, thus, pose challenges for adoption to sperm vitrification. Three-dimensional (3D) printing combined with open hardware sharing is an emerging strategy to address challenges in the development of cryo-preservation tools. The goal of this study was to develop a 3D printed Vitrification Device for Cryo-Vials (VDCV) that can be integrated with the existing vial storage systems. The VDCV combined the vitrification and handling …

Population Structure, Gene Flow, And Sex-Biased Dispersal In The Reticulated Flatwoods Salamander (Ambystoma Bishopi): Implications For Translocations, Steven T. Williams, Jean P. Elbers, Sabrina S. Taylor

Faculty Publications

Understanding patterns of gene flow and population structure is vital for managing threatened and endangered species. The reticulated flatwoods salamander (Ambystoma bishopi) is an endangered species with a fragmented range; therefore, assessing connectivity and genetic population structure can inform future conservation. Samples collected from breeding sites (n = 5) were used to calculate structure and gene flow using three marker types: single nucleotide polymorphisms isolated from potential immune genes (SNPs), nuclear data from the major histocompatibility complex (MHC), and the mitochondrial control region. At a broad geographical scale, nuclear data (SNP and MHC) supported gene flow and little structure (FST …

Deep-water access is arguably the most effective, but under-studied, mechanism that plants employ to survive during drought. Vulnerability to embolism and hydraulic safety margins can predict mortality risk at given levels of dehydration, but deep-water access may delay plant dehydration. Here, we tested the role of deep-water access in enabling survival within a diverse tropical forest community in Panama using a novel data-model approach. We inversely estimated the effective rooting depth (ERD, as the average depth of water extraction), for 29 canopy species by linking diameter growth dynamics (1990–2015) to vapor pressure deficit, water potentials in the whole-soil column, and …

Global Flash Drought Monitoring Using Surface Soil Moisture, Vinit Sehgal, Nandita Gaur, Binayak P. Mohanty Sep 2021

Global Flash Drought Monitoring Using Surface Soil Moisture, Vinit Sehgal, Nandita Gaur, Binayak P. Mohanty

Faculty Publications

Abrupt onset and swift intensification characterize flash droughts. Global surface soil moisture (θRS) from NASA's Soil Moisture Active Passive (SMAP) satellite can facilitate a near-real-time assessment of emerging flash droughts at a 36-km footprint. However, a robust flash drought monitoring using θRS must account for the (a) short observation record of SMAP, (b) nonlinear geophysical controls over θRS dynamics, and (c) emergent meteorological drivers of flash droughts. We propose a new method for near-real-time characterization of droughts using Soil Moisture Stress (SMS, drought stress) and Relative Rate of Drydown (RRD, drought stress intensification rate)—developed using SMAP θRS (March 2015–May 2021), …

A collection of six commercially available, 3D printer filaments were analyzed with respect to their gas-phase emissions, specifically volatile organic compounds (VOCs), during simulated fused filament fabrication (FFF). Filaments were chosen because they were advertised to contain metal particles or carbon nanotubes. During experimentation, some were found to contain other non-advertised additives that greatly influenced gas-phase emissions. Three polylactic acid (PLA) filaments containing either copper, bronze, or stainless steel particles were studied along in addition to three carbon nanotube (CNT) filaments made from PLA, acrylonitrile-butadiene-styrene (ABS), and polycarbonate (PC). The metal-additive PLA filaments were found to emit primarily lactide, acetaldehyde, …
