Faculty Publications

© 2020, © 2020 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group, on behalf of Shanghai Shangyixun Cultural Communication Co., Ltd. Equine parvovirus-hepatitis (EqPV-H) has recently been associated with cases of Theiler's disease, a form of fulminant hepatic necrosis in horses. To assess whether EqPV-H is the cause of Theiler's disease, we first demonstrated hepatotropism by PCR on tissues from acutely infected horses. We then experimentally inoculated horses with EqPV-H and 8 of 10 horses developed hepatitis. One horse showed clinical signs of liver failure. The onset of hepatitis was temporally associated with seroconversion and …

Fundamental Bound For Time Measurements And Minimum Uncertainty Clocks, Rodolfo Gambini, Jorge Pullin

Faculty Publications

We present a simple argument leading to a fundamental minimum uncertainty in the determination of times. It only relies in the uncertainty principle and time dilation in a gravitational field. It implies any attempt to measure times will have a fundamental level of uncertainty. Implications are briefly outlined.

Rotation And Spin And Position Operators In Relativistic Gravity And Quantum Electrodynamics, Robert F. O’Connell

Faculty Publications

First, we examine how spin is treated in special relativity and the necessity of introducing spin supplementary conditions (SSC) and how they are related to the choice of a center-of-mass of a spinning particle. Next, we discuss quantum electrodynamics and the Foldy–Wouthuysen transformation which we note is a position operator identical to the Pryce–Newton–Wigner position operator. The classical version of the operators are shown to be essential for the treatment of classical relativistic particles in general relativity, of special interest being the case of binary systems (black holes/neutron stars) which emit gravitational radiation.

The Gulf of Mexico (GoM) region is prone to disasters, including recurrent oil spills, hurricanes, floods, industrial accidents, harmful algal blooms, and the current COVID-19 pandemic. The GoM and other regions of the U.S. lack sufficient baseline health information to identify, attribute, mitigate, and facilitate prevention of major health effects of disasters. Developing capacity to assess adverse human health consequences of future disasters requires establishment of a comprehensive, sustained community health observing system, similar to the extensive and well-established environmental observing systems. We propose a system that combines six levels of health data domains, beginning with three existing, national surveys …

Who’S Afraid Of Ebola? Epidemic Fires And Locative Fears In The Information Age, W. Shrum, J. Aggrey, A. Campos, J. Pamplona Da Costa, J. Joseph, P. Kreimer, R. Kroeger, L. Medina, P. Miller, A. Palackal, A. Pandal De La Peza, A. Traore

Faculty Publications

Epidemics have traditionally been viewed as the widespread occurrence of infectious disease within a community, or a sudden increase above what is typical. But modern epidemics are both more and less than the diffusion of viral entities. We argue that epidemics are 'fire objects', using a term coined by Law and Singleton: They generate locative fears through encounters that focus attention on entities that are unknown or imprecisely known, transforming spaces and humans into indeterminate dangers, alternating appearance and absence. The Ebola epidemic of 2014 had more complex impacts than the number of infections would suggest. We employ multi-sited qualitative …

First Person: The Pandemic's Silver Lining: Real Talk For Future Teachers, J Hipp

Faculty Publications

When the COVID-19 pandemic closed her university campus, Jamie Hipp had to move her popular arts integration class for preservice teachers to a virtual format. She was surprised to learn that her students wanted more than regular sessions during their scheduled class times; they wanted additional opportunities for real teacher talk about going on interviews, setting up a classroom, and other practical matters that weren't being covered in their preservice program. Hipp set up a series of virtual sessions on topics of interest to students, in addition to regular class sessions. The sessions went so well that Hipp intends to …

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is the cause of Coronavirus Disease 2019 (COVID-19) and responsible for the current pandemic. Recent SARS-CoV-2 susceptibility studies in cats show that the virus can replicate in these companion animals and transmit to other cats. Here, we present an in-depth study of SARS-CoV-2 infection, disease and transmission in domestic cats. Cats were challenged with SARS-CoV-2 via intranasal and oral routes. One day post challenge (DPC), two sentinel cats were introduced. Animals were monitored for clinical signs, clinicopathological abnormalities and viral shedding. Postmortem examinations were performed at 4, 7 and 21 DPC. Viral RNA …

© 2019 Geological Society of America. A giant mass-transport complex was recently discovered in the eastern Arabian Sea, exceeding in volume all but one other known complex on passive margins worldwide. The complex, named the Nataraja Slide, was drilled by International Ocean Discovery Program (IODP) Expedition 355 in two locations where it is ~300 m (Site U1456) and ~200 m thick (Site U1457). The top of this mass-transport complex is defined by the presence of both reworked microfossil assemblages and deformation structures, such as folding and faulting. The deposit consists of two main phases of mass wasting, each consisting of …

Speciation-By-Depth On Coral Reefs: Sympatric Divergence With Gene Flow Or Cryptic Transient Isolation?, Carlos Prada, Michael E. Hellberg

Faculty Publications

© 2020 The Authors. Journal of Evolutionary Biology published by John Wiley & Sons Ltd on behalf of European Society for Evolutionary Biology The distributions of many sister species in the sea overlap geographically but are partitioned along depth gradients. The genetic changes leading to depth segregation may evolve in geographic isolation as a prerequisite to coexistence or may emerge during primary divergence leading to new species. These alternatives can now be distinguished via the power endowed by the thousands of scorable loci provided by second-generation sequence data. Here, we revisit the case of two depth-segregated, genetically isolated ecotypes of …

Improving Health Behaviors Through Community Engagement: Challenge For A Healthier Louisiana, Stephanie T. Broyles, Elizabeth A. Gollub, Allison Tohme, Peter T. Katzmarzyk

Faculty Publications

There is increasing recognition that community-based approaches may have merit in improving physical activity and healthy eating behaviors. The “Challenge for a Healthier Louisiana” program supported twelve projects that addressed the root causes of obesity through integrated community-level changes. Partnerships provided community-based obesity prevention by promoting healthier eating and/or physical activity through enhanced infrastructure, policy changes, and programming. To evaluate whether the program resulted in changes in healthy eating and/or physical activity among adults, surveys were conducted pre- and postintervention among participants. Participants who were exposed to physical activity programs were more likely to adopt the consumption of fruits (odds …

Diverging Landscape Impacts On Macronutrient Status Despite Overlapping Diets In Managed (Apis Mellifera) And Native (Melissodes Desponsa) Bees, Christina L. Mogren, Mariá Soledad Benítez, Kevin Mccarter, Frédéric Boyer, Jonathan G. Lundgren

Faculty Publications

Declining pollinator populations worldwide are attributed to multiple stressors, including the loss of quality forage. Habitat management in agricultural areas often targets honey bees (Apis mellifera L.) specifically, with the assumption that native bees will benefit from an 'umbrella species' strategy. We tested this theory using a conservation physiology approach to compare the effects of landscape composition and floral dietary composition on the physiological status of honey bees and Melissodes desponsa in eastern South Dakota, USA. The total glycogen, lipid and protein concentrations were quantified from field collected bees. Next-generation sequencing of the trnL chloroplast gene from bee guts was …

Faculty Publications

Recently, it has been widely accepted by the research community that interactions between humans and cyber-physical infrastructures have played a significant role in determining the performance of the latter. The existing paradigm for designing cyber-physical systems for optimal performance focuses on developing models based on historical data. The impacts of context factors driving human system interaction are challenging and are difficult to capture and replicate in existing design models. As a result, many existing models do not or only partially address those context factors of a new design owing to the lack of capabilities to capture the context factors. This …

The Influence Of Language Background And Second Language Phonetics Training On The Perception Of Lexical Stress In A Second Language, Todd A. Gibson, Carolina Bernales

Faculty Publications

Language background and second language (L2) training both have been found to contribute to L2 lexical stress perception. To explore their relative contributions, a lexical stress perception task was administered to a total of 129 university students of different language backgrounds. A group of 62 monolingual English-speaking students in the U.S.A. and 67 English-as-a-foreign-language students in Chile were asked to identify lexical stress in trochees and iambs. Chileans with previous phonetics training performed better than Chileans without the training and performed as well as their U.S. peers. U.S. participants and those Chileans without previous phonetics training performed better with trochees …

Rates And Predictors Of Co-Occurring Autism Spectrum Disorder In Boys With Fragile X Syndrome, Eileen Haebig, Audra Sterling, Andrea Barton-Hulsey, Laura Friedman

Faculty Publications

Background and aims: Males with fragile X syndrome display many behavioral features of autism spectrum disorder. Despite this overlap, our understanding of autism spectrum disorder symptoms and severity in fragile X syndrome is limited due to variation in assessment methods in the literature. Furthermore, the relationship between autism spectrum disorder symptoms and child characteristics, like age, language, and cognitive abilities, are not well understood in individuals with fragile X syndrome. Therefore, the first research aim was to compare the rates of autism spectrum disorder classifications from three commonly reported autism spectrum disorder assessments in the literature. Our second research aim …
