Cardiovascular, Cellular, And Neural Adaptations To Hot Yoga Versus Normal-Temperature Yoga, Kelsey C. Bourbeau, Terence A. Moriarty, Bryanne N. Bellovary, Gabriella F. Bellissimo, Jeremy B. Ducharme, Truman J. Haeny, Micah N. Zuhl

Faculty Publications

Context:

Chronic heat exposure promotes cardiovascular and cellular adaptations, improving an organism's ability to tolerate subsequent stressors. Heat exposure may also promote neural adaptations and alter the neural–hormonal stress response. Hot-temperature yoga (HY) combines mind–body exercise with heat exposure. The added heat component in HY may induce cardiovascular and cellular changes, along with neural benefits and modulation of stress hormones.

Aims:

The purpose of the present study is to compare the cardiovascular, cellular heat shock protein 70 (HSP70), neural, and hormonal adaptations of HY versus normal-temperature yoga (NY).

Settings and Design:

Twenty-two subjects (males = 11 and females = 11, …

Continuando una serie de estudios que han identificado aspectos de la identidad española que han arraigado con éxito en la población española, este estudio propone que el uso del deporte fue uno de esos aspectos exitosos. En particular se propone el caso de los héroes quijotescos, deportistas que triunfaron durante el franquismo en disciplinas individuales, como ejemplos del perfecto héroe español. Usando el caso de Federico Martín Bahamontes, se enumeran cinco características del héroe quijotesco, ilustradas en las crónicas periodísticas de la época: idealismo y fe redentora, moralidad y ejemplo de conducta, supervivencia ante la adversidad, locura generosa y heroicidad …

Model For Quantifying The Quality Of Secure Service, Paul M. Simon, Scott R. Graham, Christopher Talbot, Micah J. Hayden

Faculty Publications

Although not common today, communications networks could adjust security postures based on changing mission security requirements, environmental conditions, or adversarial capability, through the coordinated use of multiple channels. This will require the ability to measure the security of communications networks in a meaningful way. To address this need, in this paper, we introduce the Quality of Secure Service (QoSS) model, a methodology to evaluate how well a system meets its security requirements. This construct enables a repeatable and quantifiable measure of security in a single- or multi-channel network under static configurations. In this approach, the quantification of security is based …

We study the processes e⁺e⁻→ 2(π⁺π⁻)π⁰π⁰π⁰γ and 2(π⁺π⁻)π⁰π⁰ηγ in which an energetic photon is radiated from the initial state. The data were collected with the BABAR detector at SLAC. About 14 000 and 4700 events, respectively, are selected from a data sample corresponding to an integrated luminosity of 469 fb⁻¹. The invariant mass of the hadronic final state defines the effective e⁺e⁻ center-of-mass energy. The center-of-mass energies range from threshold to 4.5 GeV. …

The Effects Of Individual Differences, Non‐Stationarity, And The Importance Of Data Partitioning Decisions For Training And Testing Of Eeg Cross‐Participant Models, Alexander J. Kamrud, Brett J. Borghetti, Christine M. Schubert Kabban

Faculty Publications

EEG-based deep learning models have trended toward models that are designed to perform classification on any individual (cross-participant models). However, because EEG varies across participants due to non-stationarity and individual differences, certain guidelines must be followed for partitioning data into training, validation, and testing sets, in order for cross-participant models to avoid overestimation of model accuracy. Despite this necessity, the majority of EEG-based cross-participant models have not adopted such guidelines. Furthermore, some data repositories may unwittingly contribute to the problem by providing partitioned test and non-test datasets for reasons such as competition support. In this study, we demonstrate how improper …

A Holistic Framework Integrating Plant-Microbe-Mineral Regulation Of Soil Bioavailable Nitrogen, Amanda B. Daly, Andrea Jilling, Timothy M. Bowles, Robert W. Buchowski, Serita D. Frey, Cynthia M. Kallenbach, Marco Keiluweit, Maria Mooshammer, Joshua P. Schimel, A. Stuart Grandy

Faculty Publications

Soil organic nitrogen (N) is a critical resource for plants and microbes, but the processes that govern its cycle are not well-described. To promote a holistic understanding of soil N dynamics, we need an integrated model that links soil organic matter (SOM) cycling to bioavailable N in both unmanaged and managed landscapes, including agroecosystems. We present a framework that unifies recent conceptual advances in our understanding of three critical steps in bioavailable N cycling: organic N (ON) depolymerization and solubilization; bioavailable N sorption and desorption on mineral surfaces; and microbial ON turnover including assimilation, mineralization, and the recycling of microbial …

Entropy Of A Quantum Channel, Gilad Gour, Mark M. Wilde

Faculty Publications

The von Neumann entropy of a quantum state is a central concept in physics and information theory, having a number of compelling physical interpretations. There is a certain perspective that the most fundamental notion in quantum mechanics is that of a quantum channel, as quantum states, unitary evolutions, measurements, and discarding of quantum systems can each be regarded as certain kinds of quantum channels. Thus, an important goal is to define a consistent and meaningful notion of the entropy of a quantum channel. Motivated by the fact that the entropy of a state ρ can be formulated as the difference …

The Effect Of Phragmites Australis Dieback On Channel Sedimentation In The Mississippi River Delta: A Conceptual Modeling Study, Kelin Hu, Ehab Meselhe, J. Andrew Nyman

Faculty Publications

Phragmites australis is a globally distributed wetland plant. At the mouth of the Mississippi River, P. australis on natural levees of the network of distributary channels appears to increase the flow in the deep draft navigation channel, which, in turn, may reduce the sedimentation and benefit the navigation dredging. For several years, P. australis has been dying in the Mississippi River’s Bird’s Foot Delta, which appears to be shortening the distributary channels and increasing the lateral flow from the remaining portions. A conceptual model based on D-FLOW FM was applied to calculate channel sedimentation in a series of idealized deltaic …

The Impact Of Aquaculture On The Genetics And Distribution Of The Onuphid Annelid Diopatra Biscayensis, Matthew P. Galaska, David S. Wethey, Andrés Arias, Stanislas F. Dubois, Kenneth M. Halanych, Sarah A. Woodin

Faculty Publications

Aim

Evolutionary history of natural populations can be confounded by human intervention such as the case of decorator worm species Diopatra (Onuphidae), which have a history of being transported through anthropogenic activities. Because they build tubes and act as ecosystem engineers, they can have a large impact on the overall ecosystem in which they occur. One conspicuous member, Diopatra biscayensis, which was only described in 2012, has a fragmented distribution that includes the Bay of Biscay and the Normanno-Breton Gulf in the English Channel. This study explores the origin of these worms in the Normanno-Breton region, which has been …

Emerging Wetlands From River Diversions Can Sustain High Denitrification Rates In A Coastal Delta, Kiran Upreti, Victor H. Rivera-Monroy, Kanchan Maiti, Anne Giblin, James P. Geaghan

Faculty Publications

It is assumed that to treat excess NO3⁻ high soil organic matter content (%OM) is required to maintain high denitrification rates in natural or restored wetlands. However, this excess also represents a risk by increasing soil decomposition rates triggering peat collapse and wetland fragmentation. Here, we evaluated the role of %OM and temperature interactions controlling denitrification rates in eroding (Barataria Bay-BLC) and emerging (Wax Lake Delta-WLD) deltaic regions in coastal Louisiana using the isotope pairing (IPT) and N2:Ar techniques. We also assessed differences between total (direct denitrification + coupled nitrification-denitrification) and net (total denitrification minus nitrogen fixation) denitrification rates …

Ecosystems across the United States are changing in complex ways that are difficult to predict. Coordinated long-term research and analysis are required to assess how these changes will affect a diverse array of ecosystem services. This paper is part of a series that is a product of a synthesis effort of the U.S. National Science Foundation’s Long Term Ecological Research (LTER) network. This effort revealed that each LTER site had at least one compelling scientific case study about “what their site would look like” in 50 or 100 yr. As the site results were prepared, themes emerged, and the case …

Reconsidering Section 1983'S Nonabrogation Of Sovereign Immunity, Katherine Mims Crocker

Faculty Publications

Motivated by civil unrest and the police conduct that prompted it, Americans have embarked on a major reexamination of how constitutional enforcement works. One important component is 42 U.S.C. § 1983, which allows civil suits against any "person" who violates federal rights. The U.S. Supreme Court has long held that "person" excludes states because Section 1983 flunks a condition of crystal clarity.

This Article reconsiders that conclusion--in legalese, Section 1983's nonabrogation of sovereign immunity--along multiple dimensions. Beginning with a negative critique, this Article argues that because the Court invented the crystal-clarity standard so long after Section 1983's enactment, the caselaw …

Delivering Bad News: Crisis Communication Methods In Academic Libraries, Brittany O'Neill, Rebecca Kelley

Faculty Publications

This exploratory study analyzed the specific crisis communication methods of academic libraries. A survey was sent to library staff at Association of Research Libraries-member colleges and universities to describe if, who, when, and how they communicated bad news to their stakeholders for major, minor, and emerging crises. The findings show that respondents used multiple communication strategies, which varied based on the crisis. The data show that libraries communicated journal and database cancellations and health and safety emergencies more slowly than access issues and were more likely not to communicate those crises at all. Respondents also more frequently chose to communicate …

On The Cusp Of The Next Medical Malpractice Insurance Crisis, Philip G. Peters Jr.

Faculty Publications

Medical malpractice claims are dwindling. Total payouts are far lower than during the 2002 crisis. Yet, insurance industry profits have been sinking for a decade and are nearly in the red. After a dozen years with a “soft” insurance market, we are now on the cusp of yet another malpractice insurance crisis.

How can profits be in peril if claims have dwindled and payouts are historically low?
Answering that question requires an understanding of the insurance cycle. The cycle periodically transforms gradual increases in costs and gradual decreases in revenue into explosive increases in premiums.

The industry’s financial statistics today …

Shakespeare In The Courts, Douglas E. Abrams

Faculty Publications

This article continues the theme of recent “Writing It Right” articles in the Journal of the Missouri Bar. These articles describe how federal and state judges today frequently accent their opinions’ substantive or procedural rulings with references to cultural markers that can resonate with the advocates, parties, and judges who comprise the opinions’ readership. The courts’ broad array of cultural references demonstrates versatility. Some of my early articles in the Journal profiled judicial opinions that referenced terminologies, rules, and traditions of baseball, football, and other sports. Together these sports’ mass audiences help define American culture.

Malecek, S. T. Marley, M. Munch, E. C. Pollacco, C. D. Pruitt, B. T. Roeder, A. Saastamoinen, L. G. Sobotka, S. Upadhyayula

Faculty Publications

Background: The Efimov effect is a universal phenomenon in physics whereby three-body systems are stabilized via the interaction of an unbound two-body subsystems. A hypothetical state in C12 at 7.458-MeV excitation energy, comprising a loose structure of three α particles in mutual two-body resonance, has been suggested in the literature to correspond to an Efimov state in nuclear physics. The existence of such a state has not been demonstrated experimentally. Purpose: Using a combination of γ spectroscopy, charged-particle spectroscopy, and astrophysical rate calculations allowing for strict limits on the existence of such a state to been established here. Method: Using …

Nuclear Spin Features Relevant To Ab Initio Nucleon-Nucleus Elastic Scattering, R. B. Baker, M. Burrows, Ch Elster, K. D. Launey, P. Maris, G. Popa, S. P. Weppner

Faculty Publications

Background: Effective interactions for elastic nucleon-nucleus scattering from first principles require the use of the same nucleon-nucleon interaction in the structure and reaction calculations, as well as a consistent treatment of the relevant operators at each order. Purpose: Previous work using these interactions has shown good agreement with available data. Here, we study the physical relevance of one of these operators, which involves the spin of the struck nucleon, and examine the interpretation of this quantity in a nuclear structure context. Methods: Using the framework of the spectator expansion and the underlying framework of the no-core shell model, we calculate …

Performance Measurements Within Asynchronous Task-Based Runtime Systems: A Double White Dwarf Merger As An Application, Patrick Diehl, Dominic Marcello, Parsa Amini, Hartmut Kaiser, Sagiv Shiber, Geoffrey C. Clayton, Juhan Frank, Gregor Dais, Dirk Pfluger, David Eder, Alice Koniges, Kevin Huck

Faculty Publications

Analyzing performance within asynchronous many-task-based runtime systems is challenging because millions of tasks are launched concurrently. Especially for long-term runs, the amount of data collected becomes overwhelming. We study HPX and its performance-counter framework and autonomic performance environment for Exascale to collect performance data and energy consumption. We added HPX application-specific performance counters to the Octo-Tiger full 3-D adaptive multigrid code astrophysics application. This enables the combined visualization of physical and performance data to highlight bottlenecks with respect to different solvers. We examine the overhead introduced by these measurements, which is around 1%, with respect to the overall application runtime. …

The deep underground neutrino experiment (DUNE), a 40-kton underground liquid argon time projection chamber experiment, will be sensitive to the electron-neutrino flavor component of the burst of neutrinos expected from the next Galactic core-collapse supernova. Such an observation will bring unique insight into the astrophysics of core collapse as well as into the properties of neutrinos. The general capabilities of DUNE for neutrino detection in the relevant few- to few-tens-of-MeV neutrino energy range will be described. As an example, DUNE’s ability to constrain the νe spectral parameters of the neutrino burst will be considered.

An Efficient Alternative To The Cdc Gravid Trap For Southern House Mosquito (Diptera: Culicidae) Surveillance, Timothy D. Mcnamara, Thomas A. O'Shea-Wheller, Nicholas Delisi, Emily Dugas, Kevin A. Caillouet, Randy Vaeth, Dennis Wallette, Kristen Healy

Faculty Publications

West Nile virus (WNV) is the most prevalent arbovirus found throughout the United States. Surveillance of surface breeding Culex vectors involved in WNV transmission is primarily conducted using CDC Gravid traps. However, anecdotal claims from mosquito abatement districts in Louisiana assert that other trap types may be more suited to WNV surveillance. To test the validity of these assertions, we conducted a series of trapping trials and WNV surveillance over 3 yr to compare the efficacy of multiple trap types. First, we compared the CDC Gravid trap, CO2-baited New Standard Miniature Blacklight traps, and CO2-baited CDC light traps with either …

On The Computational Efficiency Of Les And Hybrid Rans-Les Models In Building Aerodynamics, Aly Mousaad Aly, Faiaz Khaled

Faculty Publications

Large-eddy simulation (LES) has proven to offer superior accuracy in regards to predicting surface pressures compared to the Reynolds-averaged Navier Stokes (RANS) models. However, the primary impediment is the high computational cost associated with LES. The authors attempt to investigate the computational cost and accuracy by employing different sub-grid scale (SGS) models in LES and hybrid RANS-LES models. One of the prerequisites of accurate pressure estimations is to ensure a horizontally homogeneous empty computational domain. This study aims to compare the computational competence qualitatively and quantitatively using an empty domain in regards to the ability to maintain horizontal homogeneity. The …

Nonlocal Elastodynamics And Fracture, Robert P. Lipton, Prashant K. Jha

Faculty Publications

A nonlocal field theory of peridynamic type is applied to model the brittle fracture problem. The elastic fields obtained from the nonlocal model are shown to converge in the limit of vanishing non-locality to solutions of classic plane elastodynamics associated with a running crack. We carry out our analysis for a plate subject to mode one loading. The length of the crack is prescribed a priori and is an increasing function of time.

Complementation, Local Complementation, And Switching In Binary Matroids, James Oxley, Jagdeep Singh

Faculty Publications

In 2004, Ehrenfeucht, Harju, and Rozenberg showed that any graph on a vertex set V can be obtained from a complete graph on V via a sequence of the operations of complementation, switching edges and non-edges at a vertex, and local complementation. The last operation involves taking the complement in the neighbourhood of a vertex. In this paper, we consider natural generalizations of these operations for binary matroids and explore their behaviour. We characterize all binary matroids obtainable from the binary projective geometry of rank r under the operations of complementation and switching. Moreover, we show that not all binary …
