Consequences Of Plume Encounter On Larval Fish Growth And Condition In The Gulf Of Mexico, Kelia E. Axler, Su Sponaugle, Frank Hernandez, Carla Culpepper, Robert K. Cowen Sep 2020

Consequences Of Plume Encounter On Larval Fish Growth And Condition In The Gulf Of Mexico, Kelia E. Axler, Su Sponaugle, Frank Hernandez, Carla Culpepper, Robert K. Cowen

Faculty Publications

© Inter-Research 2020. Freshwater input into nearshore continental shelf waters from coastal river-estuarine plumes can greatly alter the physical and trophic environments experienced by fish larvae. However, the biological consequences of plume encounter on larval fish survival remain equivocal, largely due to the extreme variability of these systems but also because traditional sampling techniques alone are too coarse to effectively characterize the dynamic biophysical environment at spatiotemporal scales relevant to individual larvae. Using a multidimensional approach, we simultaneously collected in situ imagery and net samples of larval fishes and zooplankton from the Mobile Bay plume (Alabama, USA) and ambient continental …

The Impact Of The Madden–Julian Oscillation On Cyclone Amphan (2020) And Southwest Monsoon Onset, Heather L. Roman-Stork, Subrahmanyam Bulusu Sep 2020

The Impact Of The Madden–Julian Oscillation On Cyclone Amphan (2020) And Southwest Monsoon Onset, Heather L. Roman-Stork, Subrahmanyam Bulusu

Faculty Publications

Cyclone Amphan was an exceptionally strong tropical cyclone in the Bay of Bengal that achieved a minimum central pressure of 907 mb during its active period in May 2020. In this study, we analyzed the oceanic and surface atmospheric conditions leading up to cyclogenesis, the impact of this storm on the Bay of Bengal, and how the processes that led to cyclogenesis, such as the Madden–Julian Oscillation (MJO) and Amphan itself, in turn impacted southwest monsoon preconditioning and onset. To accomplish this, we took a multiparameter approach using a combination of near real time satellite observations, ocean model forecasts, and …

Exploring Parents’ Ongoing Role In Romantic Development: Insights From Young Adults, Tyler B. Jamison, Hung Yuan Lo Sep 2020

Exploring Parents’ Ongoing Role In Romantic Development: Insights From Young Adults, Tyler B. Jamison, Hung Yuan Lo

Faculty Publications

Important decisions about romantic relationships are often made during adulthood, but the foundations for healthy relationships begin during childhood. Romantic development is related to experiences in the family of origin such as parenting, parents’ romantic history, and patterns of interaction within families. In order to better understand how this process unfolds into adulthood, we used relationship history interviews from 35 young adults (ages 24–40) to explore the mechanisms through which parents influence their children’s romantic development. We used Applied Thematic Analysis to guide our secondary analysis of relationship histories data. The findings suggest adult children internalize and apply the examples …

Modeling The Spatial Dynamics Of Marsh Ponds In New England Salt Marshes, G. Mariotti, A. C. Spivak, S. Y. Luk, G. Ceccherini, M. Tyrrell, M. Eagle Gonneea Sep 2020

Modeling The Spatial Dynamics Of Marsh Ponds In New England Salt Marshes, G. Mariotti, A. C. Spivak, S. Y. Luk, G. Ceccherini, M. Tyrrell, M. Eagle Gonneea

Faculty Publications

Ponds are common features on salt marshes, yet it is unclear how they affect large-scale marsh evolution. We developed a spatially explicit model that combines cellular automata for pond formation, expansion, and drainage, and partial differential equations for elevation dynamics. We use the mesotidal Barnstable marsh (MA, USA) as a case study, for which we measured pond expansion rate by remote sensing analysis over a 41-year time span. We estimated pond formation rate by comparing observed and modeled pond size distribution, and predicted pond deepening by comparing modeled and measured pond depth. The Barnstable marsh is currently in the pond …

A 5200-Year Paleoecological And Geochemical Record Of Coastal Environmental Changes And Shoreline Fluctuations In Southwestern Louisiana: Implications For Coastal Sustainability, Qiang Yao, Kam Biu Liu, Alejandro Antonio Aragón-Moreno, Erika Rodrigues, Y. Jun Xu, Nina S. Lam

Faculty Publications

This study presents a 5200-year history of coastal environmental changes and shoreline fluctuations based on a multi-proxy sedimentary record developed from the eastern end of Louisiana's Chenier Plain. Palynological, loss-on ignition, grain-size, and X-ray fluorescence data for a 525 cm sedimentary core indicate five stages of ecosystem development in the Rockefeller Wildlife Refuge since the mid-Holocene. Between 5190 and 4240 cal yr BP, the relative sea-level was much lower than the present level, and our study area was occupied by a baldcypress swamp. When the Sale-Cypremont subdelta complex formed at a western position approximately 4600 years ago, our study area …

Zika Virus Infection Causes Widespread Damage To The Inner Ear, Kathleen T. Yee, Biswas Neupane, Fengwei Bai, Douglas E. Vetter Sep 2020

Zika Virus Infection Causes Widespread Damage To The Inner Ear, Kathleen T. Yee, Biswas Neupane, Fengwei Bai, Douglas E. Vetter

Faculty Publications

Zika virus (ZIKV) has been recently recognized as a causative agent of newborn microcephaly, as well as other neurological consequences. A less well recognized comorbidity of prenatal ZIKV infection is hearing loss, but cases of hearing impairment following adult ZIKV infection have also been recognized. Diminished hearing following prenatal ZIKV infection in a mouse model has been reported, but no cellular consequences were observed. We examined the effects of ZIKV infection on inner ear cellular integrity and expression levels of various proteins important for cochlear function in type I interferon receptor null (Ifnar1−/−) mice following infection at …

What We’Ve Managed To Transcribe Thus Far: Lessons From The Blythe Owen Letter Transcription Project, Marianne Kordas

Faculty Publications

In 2016, the music librarian at Andrews University in Berrien Springs, MI launched a project to transcribe approximately 2,000 by twentieth-century American composer Blythe Owen into typed, keyword-searchable documents. The goal of the transcription project is to make these letters more accessible beyond their current archival setting, and thereby lay the foundation for further inquiry into Owen, her works, and the people she knew – among them pianist and pedagogue Rudolf Ganz, African-American composer Florence Price, and composition teacher Nadia Boulanger. Managing such a large project has proven challenging, but worth the effort. This article describes the methodology, successes, challenges, …

Quantum-Limited Squeezed Light Detection With A Camera, Elisha S. Matekole, Savannah L. Cuozzo, Nikunjkumar Prajapati, Narayan Bhusal, Hwang Lee, Irina Novikova, Eugeniy E. Mikhailov, Jonathan P. Dowling, Lior Cohen Sep 2020

Quantum-Limited Squeezed Light Detection With A Camera, Elisha S. Matekole, Savannah L. Cuozzo, Nikunjkumar Prajapati, Narayan Bhusal, Hwang Lee, Irina Novikova, Eugeniy E. Mikhailov, Jonathan P. Dowling, Lior Cohen

Faculty Publications

We present a technique for squeezed light detection based on direct imaging of the displaced-squeezed-vacuum state using a CCD camera. We show that the squeezing parameter can be accurately estimated using only the first two moments of the recorded pixel-to-pixel photon fluctuation statistics, with accuracy that rivals that of the standard squeezing detection methods such as a balanced homodyne detection. Finally, we numerically simulate the camera operation, reproducing the noisy experimental results with low signal samplings and confirming the theory with high signal samplings.

Young Adults' Short-Term Trajectories Of Moderate Physical Activity: Relations With Self-Evaluation Processes, Alex .. Garn, Kelly L. Simonton Sep 2020

Young Adults' Short-Term Trajectories Of Moderate Physical Activity: Relations With Self-Evaluation Processes, Alex .. Garn, Kelly L. Simonton

Faculty Publications

Young adults face numerous barriers that can undermine their engagement in healthy behaviors. For example, young adults on average experience disproportionally large declines in physical activity (PA) participation compared to other demographic groups. Self-evaluation processes may help explain these declines. This study investigated young adults' weekly trajectories of moderate physical activity, exploring self-evaluation processes, including self-efficacy and shame as time-varying covariates. A total of 71 young adults (Mage = 21.25,SD= 1.18; 55% male) reported moderate physical activity, exercise self-efficacy, and anticipated shame toward exercise once a week for 5 weeks. Latent growth curve models showed that a linear slope fit …

Classroom management is an important aspect for a K-12 teacher in any content area. The same applies in physical education (PE). In PE there are large spaces, students are moving, and in many cases, equipment (basketballs, rackets, hula hoops, etc.) is involved. Thus, making PE a unique challenge in regard to classroom management for PE teachers. One tool an elementary PE teacher can use for classroom management is music. For this study, one school administrator, 19 elementary-aged students and one PE teacher were interviewed to better understand their perspectives of music as a management tool in elementary PE. Findings indicate …

Redox-Sensitive Nanocomplex For Targeted Delivery Of Melittin, Bei Cheng, Peisheng Xu Sep 2020

Redox-Sensitive Nanocomplex For Targeted Delivery Of Melittin, Bei Cheng, Peisheng Xu

Faculty Publications

Although peptide therapeutics have been explored for decades, the successful delivery of potent peptides in vitro and in vivo remains challenging due to the poor stability, low cell permeability, and off-target effects. We developed a redox sensitive polymer-based nanocomplex which can efficiently and stably deliver the peptide drug melittin for cancer therapy. The nanocomplex selectively targets cancer cells through lactobionic acid mediated endocytosis and releases melittin intracellularly upon the trigger of elevated redox potential. In vivo study proved that the targeted nanocomplex shows excellent potency in inhibiting tumor growth in a xenograft colon cancer mouse model. Thus, the polymer/melittin nanocomplexes …

Faculty Publications

Persistence of Gulf War illness (GWI) pathology among deployed veterans is a clinical challenge even after almost three decades. Recent studies show a higher prevalence of obesity and metabolic disturbances among Gulf War veterans primarily due to the existence of post-traumatic stress disorder (PTSD), chronic fatigue, sedentary lifestyle, and consumption of a high-carbohydrate/high-fat diet. We test the hypothesis that obesity from a Western-style diet alters host gut microbial species and worsens gastrointestinal and neuroinflammatory symptom persistence. We used a 5 month Western diet feeding in mice that received prior Gulf War (GW) chemical exposure to mimic the home phase obese …

Nerve guidance conduits (NGCs) have emerged from recent advances within tissue engineering as a promising alternative to autografts for peripheral nerve repair. NGCs are tubular structures with engineered biomaterials, which guide axonal regeneration from the injured proximal nerve to the distal stump. NGC design can synergistically combine multiple properties to enhance proliferation of stem and neuronal cells, improve nerve migration, attenuate inflammation and reduce scar tissue formation. The aim of most laboratories fabricating NGCs is the development of an automated process that incorporates patient-specific features and complex tissue blueprints (e.g. neurovascular conduit) that serve as the basis for more complicated …

First-Order Comprehensive Adjoint Method For Computing Operator-Valued Response Sensitivities To Imprecisely Known Parameters, Internal Interfaces And Boundaries Of Coupled Nonlinear Systems: Ii. Application To A Nuclear Reactor Heat Removal Benchmark, Dan Gabriel Cacuci Sep 2020

First-Order Comprehensive Adjoint Method For Computing Operator-Valued Response Sensitivities To Imprecisely Known Parameters, Internal Interfaces And Boundaries Of Coupled Nonlinear Systems: Ii. Application To A Nuclear Reactor Heat Removal Benchmark, Dan Gabriel Cacuci

Faculty Publications

This work illustrates the application of a comprehensive first-order adjoint sensitivity analysis methodology (1st-CASAM) to a heat conduction and convection analytical benchmark problem which simulates heat removal from a nuclear reactor fuel rod. This analytical benchmark problem can be used to verify the accuracy of numerical solutions provided by software modeling heat transport and fluid flow systems. This illustrative heat transport benchmark shows that collocation methods require one adjoint computation for every collocation point while spectral expansion methods require one adjoint computation for each cardinal function appearing in the respective expansion when recursion relations cannot be developed between the corresponding …

Avoided Quantum Criticality In Exact Numerical Simulations Of A Single Disordered Weyl Cone, Justin H. Wilson, David A. Huse, S. Das Sarma, J. H. Pixley Sep 2020

Avoided Quantum Criticality In Exact Numerical Simulations Of A Single Disordered Weyl Cone, Justin H. Wilson, David A. Huse, S. Das Sarma, J. H. Pixley

Faculty Publications

Existing theoretical works differ on whether three-dimensional Dirac and Weyl semimetals are stable to a short-range-correlated random potential. Numerical evidence suggests the semimetal to be unstable, while some field-theoretic instanton calculations have found it to be stable. The differences go beyond method: the continuum field-theoretic works use a single, perfectly linear Weyl cone, while numerical works use tight-binding lattice models which inherently have band curvature and multiple Weyl cones. In this work, we bridge this gap by performing exact numerics on the same model used in analytic treatments, and we find that all phenomena associated with rare regions near the …

Cyclic Topology Enhancing Structural Ordering And Stability Of Comb-Shaped Polypeptoid Thin Films Against Melt-Induced Dewetting, Naisheng Jiang, Jianxia Chen, Tianyi Yu, Albert Chao, Liying Kang, Ying Wu, Kangmin Niu, Ruipeng Li, Masafumi Fukuto, Donghui Zhang

Faculty Publications

Copyright © 2020 American Chemical Society. We investigated the effect of cyclic chain topology on the molecular ordering and thermal stability of comb-shaped polypeptoid thin films on silicon (Si) substrates. Cyclic and linear poly(N-decylglycine) (PNDG) bearing long n-decyl side chains were synthesized by ring-opening polymerization of N-decylglycine-derived N-carboxyanhydrides. When the spin-coated thin films were subjected to thermal annealing at temperatures above the melting temperature (T > Tm), the cyclic PNDG films exhibited significantly enhanced stability against melt-induced dewetting than the linear counterparts (l-PNDG). When recrystallized at temperatures below the crystallization temperature (T < Tc), the homogeneous c-PNDG films exhibit enhanced crystalline ordering relative to the macroscopically dewetted l-PNDG films. Both cyclic and linear PNDG molecules adopt cis-amide conformations in the crystalline film, which transition into trans-amide conformations upon melting. A top-down solvent leaching treatment of both l/c-PNDG films revealed the formation of an irreversibly physisorbed monolayer with similar thickness (ca. 3 nm) on the Si substrate. The physisorbed monolayers are more disordered relative to the respective thicker crystalline films for both cyclic and linear PNDGs. Upon heating above Tm, the adsorbed c-PNDG chains adopt trans-amide backbone conformation identical with the free c-PNDG molecules in the molten film. By contrast, the backbone conformations of l-PNDG chains in the adsorbed layers are notably different from those of the free chains in the molten film. We postulate that the conformational disparity between the chains in the physically adsorbed layers versus the free chains in the molten film is an important factor to account for the difference in the thermal stability of PNDG thin films. These findings highlight the use of cyclic chain topology to suppress the melt-induced dewetting in polymer thin films.

First-Order Comprehensive Adjoint Method For Computing Operator-Valued Response Sensitivities To Imprecisely Known Parameters, Internal Interfaces And Boundaries Of Coupled Nonlinear Systems: I. Mathematical Framework, Dan Gabriel Cacuci

Faculty Publications

This work presents the first-order comprehensive adjoint sensitivity analysis methodology (1st-CASAM) for computing efficiently the first-order sensitivities (i.e., functional derivatives) of operator-valued responses (i.e., model results) of general models of coupled nonlinear physical systems characterized by imprecisely known or and/or uncertain parameters, external boundaries, and internal interfaces between the coupled systems. The explicit mathematical formalism developed within the 1st-CASAM for computing the first-order sensitivities of operator-valued response to uncertain internal interfaces and external boundaries in the models’ phase–space enables this methodology to generalize all of the previously published methodologies for computing first-order response sensitivities. The computational resources needed for using …

On May 21, 2019 at 03:02:29 UTC Advanced LIGO and Advanced Virgo observed a short duration gravitational-wave signal, GW190521, with a three-detector network signal-to-noise ratio of 14.7, and an estimated false-alarm rate of 1 in 4900 yr using a search sensitive to generic transients. If GW190521 is from a quasicircular binary inspiral, then the detected signal is consistent with the merger of two black holes with masses of 85-14+21 Mm and 66-18+17 Mm (90% credible intervals). We infer that the primary black hole mass lies within the gap produced by (pulsational) pair-instability supernova processes, with only a 0.32% probability of …

Presented is the description of a new and general method used to search for γ-ray counterparts to gravitational-wave (GW) triggers. This method is specifically applied to single GW detector triggers. Advanced LIGO data from observing runs O1 and O2 were analyzed, thus each GW trigger comes from either the LIGO-Livingston or the LIGO-Hanford interferometer. For each GW trigger, Fermi Gamma-ray burst monitor data is searched and the most significant subthreshold signal counterpart is selected. Then, a methodology is defined in order to establish which of the GW-γ-ray trigger pairs are likely to have a common origin. For that purpose an …

Faculty Publications

Displaced left-turn (DLT) intersections are designed to increase the mobility of vehicles by relocating the left-turn lane (lanes) to the far-left side of the road upstream of the main signalized intersection. Since DLT is a relatively new design and very limited crash data are available, previous studies have focused mainly on the analysis of its operational performance rather than its safety performance. To fill this gap, in this study, we investigated the safety performance of two DLT intersections located in San Marcos, Texas. Crash data from 2011 to April 2018 were extracted from the TxDOT Crash Record Information System (CRIS). …

© 2020 authors. Published by the American Physical Society. On May 21, 2019 at 03:02:29 UTC Advanced LIGO and Advanced Virgo observed a short duration gravitational-wave signal, GW190521, with a three-detector network signal-to-noise ratio of 14.7, and an estimated false-alarm rate of 1 in 4900 yr using a search sensitive to generic transients. If GW190521 is from a quasicircular binary inspiral, then the detected signal is consistent with the merger of two black holes with masses of 85-14+21 Mm and 66-18+17 Mm (90% credible intervals). We infer that the primary black hole mass lies within the gap produced by (pulsational) …
