A Reference Genome For The Nectar-Robbing Black-Throated Flowerpiercer (Diglossa Brunneiventris), A E. Hiller, R T. Brumfield, B C. Faircloth Nov 2021

A Reference Genome For The Nectar-Robbing Black-Throated Flowerpiercer (Diglossa Brunneiventris), A E. Hiller, R T. Brumfield, B C. Faircloth

Faculty Publications

Black-throated Flowerpiercers (Diglossa brunneiventris) are one species representing a phenotypically specialized group of tanagers (Thraupidae) that have hooked bills which allow them to feed by stealing nectar from the base of flowers. Members of the genus are widely distributed in montane regions from Mexico to northern Argentina, and previous studies of Diglossa have focused on their systematics, phylogenetics, and interesting natural history. Despite numerous studies of species within the genus, no genome assembly exists to represent these nectivorous tanagers. We described the assembly of a genome sequence representing a museum-vouchered, wild, female D. brunneiventris collected in Peru. By combining Pacific …

The CALorimetric Electron Telescope CALET is collecting science data on the International Space Station since October 2015 with excellent and continuous performance. Energy is measured with a deep homogeneous calorimeter (1.2 nuclear interaction lengths, 27 radiation lengths) preceded by an imaging pre-shower (3 radiation lengths, 1mm granularity) providing tracking and 10-5 electron/proton discrimination. Two independent sub-systems identify the charge Z of the incident particle from proton to iron and above (Z<40). CALET measures the cosmic-ray electron + positron flux up to 20 TeV, gamma rays up to 10 TeV, and nuclei up to the PeV scale. In this paper, we report the on-orbit performance of the instrument and summarize the main results obtained during the first 5 years of operation, including the electron + positron energy spectrum and the individual spectra of protons, heavier nuclei and iron. Solar modulation and gamma-ray observations are also concisely reported, as well as transient phenomena and the search for gravitational wave counterparts.


Use Of Racial And Ethnic Categories In Medical Testing And Diagnosis: Primum Non Nocere, Jay S. Kaufman, Joanna Merckx, Richard S. Cooper Nov 2021

Use Of Racial And Ethnic Categories In Medical Testing And Diagnosis: Primum Non Nocere, Jay S. Kaufman, Joanna Merckx, Richard S. Cooper

Faculty Publications

BACKGROUND: Use of race and ethnicity is common in medical tests and procedures, even though these categories are defined by sociological, historical, and political processes, and vary considerably in their definitions over time and place. Because all societies organize themselves around these constructs in some way, they are undeniable facets of the human experience, with myriad health consequences. In the biomedical literature, they are also commonly interpreted as representing biological heterogeneity that is relevant for health and disease. CONTENT: We review the use of race and ethnicity in medical practice, especially in the USA, and provide 2 specific examples to …

Coleoptera are visible members of food webs in tea plantations, with high species richness and abundance. Many tea pests, as well as natural enemies, are members of this order, so a knowledge of how groundcovers affect beetles can aid pest management. We collected beetles in a replicated field experiment in the Wuyi Mountains, Fujian Province, China. Tea was intercropped with Paspalum notatum or Chamaecrista rotundifolia, or rows were cleared to bare ground, or in the control they were left unmanaged to allow weeds to grow naturally. Sampling, done by sweep netting and vegetation beating, was conducted monthly, between May 2006 …

Word-Learning Trajectories Influence Long-Term Recall In Children With Developmental Language Disorder And Typical Development, Justin B. Kueser, Laurence B. Leonard, Patricia Deevy, Eileen Haebig, Jeffrey D. Karpicke

Faculty Publications

Introduction: Children with developmental language disorder (DLD) have difficulties learning words. However, the severity of these difficulties can be reduced through word learning procedures that incorporate repeated spaced retrieval (RSR). Previous studies have shown positive outcomes with RSR but we still know very little about how learning unfolds with this procedure. In this study, we focus on the process of learning under RSR. Methods: We analyze the learning data from children with DLD and with typical development (TD) from three recent studies using RSR. We fit growth curves to the trial-by-trial learning data for immediate and spaced retrieval trials and …

Grow Fast, Die Young: Does Compensatory Growth Reduce Survival Of Juvenile Blacktip Sharks (Carcharhinus Limbatus) In The Western Gulf Of Mexico?, Philip Matich, Jeffrey D. Plumlee, Mark Fisher

Faculty Publications

Effective conservation and management necessitate an understanding of the ecological mechanisms that shape species life histories in order to predict how variability in natural and anthropogenic impacts will alter growth rates, recruitment, and survival. Among these mechanisms, the interaction between parturition timing and prey availability frequently influences offspring success, particularly when postnatal care is absent. Here, we assess how parturition timing and nursery conditions, including prey abundance and environmental conditions, influence the growth and potential survival of blacktip sharks (Carcharhinus limbatus) in western Gulf of Mexico (GOM) estuaries over their first year. Catch data from long-term gillnet monitoring allowed for …

Tropical cyclones are the most powerful storms on earth, causing catastrophic damage to human lives and infrastructure. Hurricanes also cause wildlife mortality when they make landfall, but the severity of these effects is difficult to quantify because data collection is either logistically impossible or deprioritized in the wake of human tragedy. On August 27, 2020, Hurricane Laura made landfall in southwestern Louisiana with maximum sustained winds of 241 kph (150 mph), making it one of the most powerful storms to strike the mainland United States. Hurricane Laura passed directly over the core breeding range of the western Gulf Coast population …

Warming from climate change is expected to reduce body size of endotherms, but studies from temperate systems have produced equivocal results. Over four decades, we collected morphometric data on a nonmigratory understory bird community within Amazonian primary rainforest that is experiencing increasingly extreme climate. All 77 species showed lower mean mass since the early 1980s-nearly half with 95% confidence. A third of species concomitantly increased wing length, driving a decrease in mass:wing ratio for 69% of species. Seasonal precipitation patterns were generally better than temperature at explaining morphological variation. Short-term climatic conditions affected all metrics, but time trends in wing …

The United States is in the midst of a crisis in confidence in elections, despite the many process protections baked into every stage of election administration. Part of the problem is that few Americans know just how rigorous the protections in place are, and most Americans have no concept of how modern elections are run. Election observation statutes are intended to provide a window for members of the public to learn about and oversee the process and to satisfy themselves that elections are fair and that outcomes are reliable. Yet in 2020, in part due to unforeseen pandemic conditions, election …

This work presents a measurement uncertainty analysis for a system designed to simultaneously capture specular in-plane and out-of-plane bidirectional reflectance distribution function (BRDF) data with high spatial resolution by augmenting the Complete Angle Scatter Instrument (CASI®) with a charge-coupled device (CCD) camera. Various scatter flux, incident flux, scatter angle, and detector solid angle uncertainty contributions are considered and evaluated based on imperfectly known system parameters. In particular, incident flux temporal fluctuation, detector noise and non-linearity, and out-of-plane aperture misalignment considerations each require significant adjustment from original CASI® uncertainty analysis, and expressions for neutral density (ND) filter, scatter angle, and solid …

Prisons can utilize effective operations management and continuous improvement techniques to fulfil the obligations of stakeholders and provide an opportunity to try and support the rehabilitation of inmates. Iowa Prison Industries (IPI) offers a work training program for incarcerated individuals under the supervision of the Iowa Department of Corrections (IDOC). The program works with approximately 800 incarcerated “associates” to help them acquire skills necessary to obtain gainful employment upon release. This article shares some of the history of IPI’s Operational Excellence (OpEx) as well as reports on program impact. Preliminary findings and success outcomes have been encouraging.


Low Light Intensity Delays Vegetative Phase Change, Mingli Xu, Tieqiang Hu, R Scott Poethig Nov 2021

Low Light Intensity Delays Vegetative Phase Change, Mingli Xu, Tieqiang Hu, R Scott Poethig

Faculty Publications

Plants that develop under low light (LL) intensity often display a phenotype known as the “shade tolerance syndrome (STS)”. This syndrome is similar to the phenotype of plants in the juvenile phase of shoot development, but the basis for this similarity is unknown. We tested the hypothesis that the STS is regulated by the same mechanism that regulates the juvenile vegetative phase by examining the effect of LL on rosette development in Arabidopsis (Arabidopsis thaliana). We found that LL prolonged the juvenile vegetative phase and that this was associated with an increase in the expression of the master …

We find ourselves at a momentous turn in the history of vaccines. The COVID-19 pandemic triggered a quasi-global vaccine race that not only compressed vaccine research and development (R&D) timelines, but also paved the way for the administration of a new type of vaccine technology – mRNA vaccines, which work in substantially different ways from the vaccines in use before the pandemic.

While the process of bringing emerging COVID-19 vaccines to market has taken place in an unusually short timeframe, it was largely predicated on the same scientific and regulatory processes that govern the development, approval and deployment of new …

We propose computational methods for (i) completion of partially observed curves; (ii) assessment of completion variability through a nonparametric multiple imputation procedure; (iii) development of nearest neighbor classifiers compatible with the completion techniques. Our contributions are founded on exploiting the geometric notion of shape of a curve, defined as those aspects of a curve that remain unchanged under translations, rotations and reparameterizations. Explicit incorporation of shape information into the computational methods plays the dual role of limiting the set of all possible completions …

The observation of 236 MeV muon neutrinos from kaon-decay-at-rest (KDAR) originating in the core of the Sun would provide a unique signature of dark matter annihilation. Since excellent angle and energy reconstruction are necessary to detect this monoenergetic, directional neutrino flux, DUNE with its vast volume and reconstruction capabilities, is a promising candidate for a KDAR neutrino search. In this work, we evaluate the proposed KDAR neutrino search strategies by realistically modeling both neutrino-nucleus interactions and the response of DUNE. We find that, although reconstruction of the neutrino energy and direction is difficult with current techniques in the relevant energy …


Vowel Pronunciation As An Ethnic Marker: Pacific Islander Teens In Utah, Lisa M. Johnson Oct 2021

Vowel Pronunciation As An Ethnic Marker: Pacific Islander Teens In Utah, Lisa M. Johnson

Faculty Publications

Despite the growing numbers and visibility of Native Hawaiians and other Pacific Islanders (NHPIs) in the U.S., these Americans are generally overlooked in the research on language variation. American dialectology tends to focus on speakers of European descent, and most research on minority ethno-racial groups has concentrated on larger demographic groups, such as African American and Latinx American groups. This combination of research deficits limits our understanding of linguistic variation and the social forces that influence it. In addition, it may reinforce stereotypes of “ethnolects” as nonstandard and wholly separate from regional and stylistic influence. (See Eckert, 2008.) Many of …

Theoretical and experimental studies are presented to characterize the anisotropic plastic response under torsion loading of two nominally identical aluminum Al6061-T6 extruded round bars. Theoretical models are developed using isotropic (Von Mises 1913) and anisotropic (Barlat 1991) yield criteria, along with isotropic strain hardening formulae, to model post-yield behavior under simple torsion loading. For the case of simple shear loading, incremental plasticity theory is used to determine the theoretical elastic, plastic, and total shear strains. A set of experiments are performed to calibrate Barlat’s 1991 yield function. Several specimens are extracted at different orientations to the longitudinal direction of each …
