Reduced-Order Fast Converging Observers For Systems With Discrete Measurements And Measurement Error, Frédéric Mazenc, Michael Malisoff, Zhong Ping Jiang Apr 2021

Reduced-Order Fast Converging Observers For Systems With Discrete Measurements And Measurement Error, Frédéric Mazenc, Michael Malisoff, Zhong Ping Jiang

Faculty Publications

We provide novel reduced-order observer designs for continuous-time nonlinear systems with measurement error. Our first result applies to systems with continuous output measurements, and provides observers that converge in a fixed finite time that is independent of the initial state when the measurement error is zero. Our second result applies under discrete measurements, and provides observers that converge asymptotically with a rate of convergence that is proportional to the negative of the logarithm of the size of a sampling interval. Our observers satisfy an enhanced input-to-state stability property with respect to the measurement error, in which an overshoot term only …

Su(3)-Guided Realistic Nucleon-Nucleon Interactions For Large-Scale Calculations, G. H. Sargsyan, K. D. Launey, R. B. Baker, T. Dytrych, J. P. Draayer Apr 2021

Su(3)-Guided Realistic Nucleon-Nucleon Interactions For Large-Scale Calculations, G. H. Sargsyan, K. D. Launey, R. B. Baker, T. Dytrych, J. P. Draayer

Faculty Publications

We examine nucleon-nucleon realistic interactions, based on their SU(3) decomposition to SU(3)-symmetric components. We find that many of these interaction components are negligible, which, in turn, allows us to identify a subset of physically relevant components that are sufficient to describe the structure of low-lying states in C12 and related observables, such as excitation energies, electric quadrupole transitions, and rms radii. We find that paring down the interaction by half or more yields results that practically coincide with the corresponding ab initio calculations with the full interaction. In addition, we show that while various realistic interactions differ in their SU(3) …

Faculty Publications

Polyurethane (PU) foams reinforced with bamboo fiber sources in China, i.e., bamboo fiber, bamboo α-cellulose fiber, and bamboo nanocellulose fiber, were prepared and their physico-mechanical properties were analyzed in this work. The bamboo fiber sources and PU foams were characterized by Fourier transform infrared spectroscopy (FTIR), Scanning electron microscope (SEM), Thermal gravimetric analysis (TGA) and universal compression testing. The results indicated that the hydroxyl groups on the fiber surfaces were enhanced by removing non-celluloses in the preparation of α-cellulose and nanocellulose. With the addition of small particle size α-cellulose and nanocellulose, the cell sizes of PU foams were reduced due …

Stakeholder’S Risk Perceptions Ofwild Pigs: Is There A Gender Difference?, Maria Bampasidou, Michael D. Kaller, Shaun M. Tanger Apr 2021

Stakeholder’S Risk Perceptions Ofwild Pigs: Is There A Gender Difference?, Maria Bampasidou, Michael D. Kaller, Shaun M. Tanger

Faculty Publications

Substantial literature indicates that genders differ in terms of risk perception and values regarding wildlife management. Lack of equal stakeholder representation is also documented, which can also impact the effectiveness of human-wildlife conflict resolution interventions and education and outreach efforts. This paper investigates gender differences in perceptions about risks and potential adverse impacts on production, health, environment, safety, and population management posed by wild pigs. A survey was used to collect data from a random sample of adult residents (N = 1221) in Louisiana. We analyzed responses from 226 female and 832 male producers. We observed differences in how these …

A Generalized Approach For Sperm Cryopreservation In The Genus Pomoxis: Sperm Cryopreservation And Fertilization Efficiency Of Black-Stripe Black Crappie, Pomoxis Nigromaculatus, Christian A. Shirley, Michael E. Colvin, Terrence R. Tiersch, Peter J. Allen Apr 2021

A Generalized Approach For Sperm Cryopreservation In The Genus Pomoxis: Sperm Cryopreservation And Fertilization Efficiency Of Black-Stripe Black Crappie, Pomoxis Nigromaculatus, Christian A. Shirley, Michael E. Colvin, Terrence R. Tiersch, Peter J. Allen

Faculty Publications

Approaches for white crappie, Pomoxis annularis sperm cryopreservation have led to interest in applying similar methods to black-stripe black crappie, Pomoxis nigromaculatus. Their rarity in wild populations makes them a preferred phenotype for hatchery use. Sperm cryopreservation procedures were compared between black-stripe black crappie and white crappie for sperm motility and egg fertilization rate. There was no difference in black-stripe black crappie sperm motility after thawing between 5% dimethyl sulfoxide (DMSO, 45% motility) and 10% methanol (50% motility). However, fertilization rates were higher (p <.001) for sperm cryoprotected with 5% DMSO (38 ± 8%) than 10% methanol (22 ± 7%). Hatchery use requires sperm-to-egg ratios and fertilizing potential of single doses (i.e., 0.5 ml straw). Using black-stripe black crappie sperm (2.5 × 108 sperm/ml; 5% DMSO), the highest fertilization (27%) was found using single straws with 785 eggs (0.25 ml); total sperm:egg ratio: 159,000:1; motile sperm:egg ratio: 71,700:1. Therefore, sperm of two Pomoxis species could be cryopreserved using 350 mOsmol/kg Hanks' balanced salt solution as an extender, 5% DMSO as a cryoprotectant, cooling at 40°C/min, and thawing for 8 s at 40°C to maintain sperm motility and fertility. Basic protocols can be generalized within a genus if variables such as sperm concentration, process timing, and sample volumes are controlled.

Global Well-Posedness For The Logarithmically Energy-Supercritical Nonlinear Wave Equation With Partial Symmetry, Aynur Bulut, Benjamin Dodson Apr 2021

Global Well-Posedness For The Logarithmically Energy-Supercritical Nonlinear Wave Equation With Partial Symmetry, Aynur Bulut, Benjamin Dodson

Faculty Publications

We establish global well-posedness and scattering results for the logarithmically energy-supercritical nonlinear wave equation, under the assumption that the initial data satisfies a partial symmetry condition. These results generalize and extend work of Tao in the radially symmetric setting. The techniques involved include weighted versions of Morawetz and Strichartz estimates, with weights adapted to the partial symmetry assumptions. In an appendix, we establish a corresponding quantitative result for the energy-critical problem.

Genes Related To Redox And Cell Curvature Facilitate Interactions Between Caulobacter Strains And Arabidopsis, Louis Berrios, Bert Ely Apr 2021

Genes Related To Redox And Cell Curvature Facilitate Interactions Between Caulobacter Strains And Arabidopsis, Louis Berrios, Bert Ely

Faculty Publications

Bacteria play an integral role in shaping plant growth and development. However, the genetic factors that facilitate plant-bacteria interactions remain largely unknown. Here, we demonstrated the importance of two bacterial genetic factors that facilitate the interactions between plant-growth-promoting (PGP) bacteria in the genus Caulobacter and the host plant Arabidopsis. Using homologous recombination, we disrupted the cytochrome ubiquinol oxidase (cyo) operon in both C. vibrioides CB13 and C. segnis TK0059 by knocking out the expression of cyoB (critical subunit of the cyo operon) and showed that the mutant strains were unable to enhance the growth of Arabidopsis. In addition, disruption of …

What Is Refractory Organic Matter In The Ocean?, Federico Baltar, Xosé A. Alvarez-Salgado, Javier Arístegui, Ronald Benner, Dennis A. Hansell, Gerhard J. Herndl, Christian Lønborg Apr 2021

What Is Refractory Organic Matter In The Ocean?, Federico Baltar, Xosé A. Alvarez-Salgado, Javier Arístegui, Ronald Benner, Dennis A. Hansell, Gerhard J. Herndl, Christian Lønborg

Faculty Publications

About 20% of the organic carbon produced in the sunlit surface ocean is transported into the ocean’s interior as dissolved, suspended and sinking particles to be mineralized and sequestered as dissolved inorganic carbon (DIC), sedimentary particulate organic carbon (POC) or “refractory” dissolved organic carbon (rDOC). Recently, the physical and biological mechanisms associated with the particle pumps have been revisited, suggesting that accepted fluxes might be severely underestimated (Boyd et al., 2019; Buesseler et al., 2020). Perhaps even more poorly understood are the mechanisms driving rDOC production and its potential accumulation in the ocean. On the basis of …

Germline mutations in BRAF and other components of the MAPK pathway are associated with the congenital syndromes collectively known as RASopathies. Here, we report the association of Septo-Optic Dysplasia (SOD) including hypopituitarism and Cardio-Facio-Cutaneous (CFC) syndrome in patients harbouring mutations in BRAF. Phosphoproteomic analyses demonstrate that these genetic variants are gain-of-function mutations leading to activation of the MAPK pathway. Activation of the MAPK pathway by conditional expression of the BrafV600E/+ allele, or the knock-in BrafQ241R/+ allele (corresponding to the most frequent human CFC-causing mutation, BRAF p.Q257R), leads to abnormal cell lineage determination and terminal differentiation of …

Non-Steroidal Anti-Inflammatory Drugs On Core Body Temperature During Exercise: A Systematic Review, Dawn M. Emerson, Stephen Cl Chen, Melani R. Kelly, Bryant Parnell, Toni M. Torres-Mcgehee Apr 2021

Non-Steroidal Anti-Inflammatory Drugs On Core Body Temperature During Exercise: A Systematic Review, Dawn M. Emerson, Stephen Cl Chen, Melani R. Kelly, Bryant Parnell, Toni M. Torres-Mcgehee

Faculty Publications

BACKGROUND: Because of their anti-pyretic effects, some individuals prophylactically use non-steroidal anti-inflammatory drugs (NSAIDs) to blunt core temperature (Tc) increases during exercise, thus, potentially improving performance by preventing hyperthermia and/or exertional heat illness. However, NSAIDs induce gastrointestinal damage, alter renal function, and decrease cardiovascular function, which could compromise thermoregulation and increase Tc. The aim of this systematic review was to evaluate the effects of NSAIDs on Tc in exercising, adult humans. METHODS: We conducted searches in MEDLINE, PubMed, Cochrane Reviews, and Google Scholar for literature published up to November 2020. We conducted a quality assessment review using the Physiotherapy Evidence …

High-Order Wave-Damage Interaction Coefficients (Wdic) Extracted Through Modal Decomposition, Hanfei Mei, Victor Giurgiutiu Apr 2021

High-Order Wave-Damage Interaction Coefficients (Wdic) Extracted Through Modal Decomposition, Hanfei Mei, Victor Giurgiutiu

Faculty Publications

This paper presents a new technique for the extraction of high-order wave-damage interaction coefficients (WDIC) through modal decomposition. The frequency and direction dependent complex-valued WDIC are used to model the scattering and mode conversion phenomena of guided wave interaction with damage. These coefficients are extracted from the harmonic analysis of local finite element model (FEM) mesh with non-reflective boundaries (NRB) and they are capable of describing the amplitude and phase of the scattered waves as a function of frequency and direction. To extract the WDIC of each wave mode, all the possible propagating wave modes are considered to be scattered …

On The Stability Of Neon Cluster Ions – Evidence For Isomeric Structures, Siegfried Kollotzek, Stefan Bergmeister, Lukas Tiefenthaler, Simon Albertini, Elisabeth Gruber, Fabio Zappa, Paul Scheier, Olof Echt

Faculty Publications

We have adopted the newly developed technique of growing cationic clusters in size-to-charge selected helium nanodroplets (HNDs), with subsequent removal of helium in a collision cell, to record high-resolution mass spectra of Nen+. Growth in singly charged HNDs leads to mass spectra that feature the same anomalies in the cluster ion abundance as in previous work, namely maxima at n = 14, 21, 55/56, 75. Several other, weaker but statistically significant anomalies are observed at n = 9, 26, 29, 33, 35, 69, 82, 89. However, when neon clusters are grown in larger HNDs, which are likely to be multiply …

Are Granulins Copper Sequestering Proteins?, Anukool A. Bhopatkar, Vijayaraghavan Rangachari Apr 2021

Are Granulins Copper Sequestering Proteins?, Anukool A. Bhopatkar, Vijayaraghavan Rangachari

Faculty Publications

Granulins (GRN 1-7) are short (~6 kDa), cysteine-rich proteins that are generated upon the proteolytic processing of progranulin (PGRN). These peptides, along with their precursor, have been implicated in multiple pathophysiological roles, especially in neurodegenerative diseases. Previously we showed that GRN-3 and GRN-5 are fully disordered in the reduced form implicating redox sensitive attributes to the proteins. Redox-based modulations are often carried out by metalloproteins in mitigating oxidative stress and maintaining metal-homeostasis within cells. To probe whether GRNs play a role in metal sequestration, we tested the metal binding propensity of the reduced forms of GRNs −3 and − 5 …

Temperature Dependence Of Density And Viscosity Of Biobutanol-Gasoline Blends, Daniel Trost, Adam Polcar, Dorin Boldor, Divine Bup Nde, Artur Wolak, Vojtĕch Kumbár

Faculty Publications

Butanol seems to be an eligible fuel for compensating for the increasing fuel consumption. Biobutanol could be produced from local sources in the place of use. Its properties show similar results to gasoline, so biobutanol could be added as a biocomponent into fuels. Important properties, in the case of blending biobutanol into gasoline, are its fluid properties and their dependence on the temperature. Therefore, in this paper, the volumetric mass density and viscosity of the selected ratios between biobutanol and gasoline (0, 5, 10, 85, 100 vol.%) were tested over the temperature range from -10 °C up to 40 °C. …
