Metrics For Performance Quantification Of Adaptive Mesh Refinement, Nicole Beisiegel, Cristóbal E. Castro, Jörn Behrens

Articles

Non-uniform, dynamically adaptive meshes are a useful tool for reducing computational complexities for geophysical simulations that exhibit strongly localised features such as is the case for tsunami, hurricane or typhoon prediction. Using the example of a shallow water solver, this study explores a set of metrics as a tool to distinguish the performance of numerical methods using adaptively refined versus uniform meshes independent of computational architecture or implementation. These metrics allow us to quantify how a numerical simulation benefits from the use of adaptive mesh refinement. The type of meshes we are focusing on are adaptive triangular meshes that are …

Shared And Anxiety-Specific Pediatric Psychopathology Dimensions Manifest Distributed Neural Correlates, Julia O. Linke, Rany Abend, Katharina Kircanski, Michal Clayton, Caitlin Stavish, Brenda E. Benson, Melissa A. Brotman, Olivier Renaud, Stephen M. Smith, Anderson M. Winkler

School of Medicine Publications

Background:

Imaging research has not yet delivered reliable psychiatric biomarkers. One challenge, particularly among youth, is high comorbidity. This challenge might be met through canonical correlation analysis (CCA) designed to model mutual dependencies between symptom dimensions and neural measures. We map the multivariate associations that intrinsic functional connectivity manifests with pediatric symptoms of anxiety, irritability, and attention-deficit/hyperactivity disorder (ADHD) as common, impactful, co-occurring problems. We evaluate the replicability of such latent dimensions in an independent sample.

Methods:

We obtained ratings of anxiety, irritability, and ADHD, and 10 minutes of resting-state functional magnetic resonance imaging data, from two independent cohorts. Both …

This study investigates the difficulties that Iraqi EFL learners face in uttering English British complex vowels; diphthongs and triphthongs in connected speech. It reports on the pronunciation test performed by the fourth level college learners whose Baghdadi Arabic is their mother tongue. Gender is of interest to this study to find out if females experience more hardship and perpetrate more mistakes than females or vice versa. Poor pronunciation leads to miscommunication, that is why this study is concerned with the phonology, and how words are pronounced within sentences, as being the main channel of communication is speech, especially with correct …

Stylistic Analysis “The Snake”– By D.H. Lawrence, Munna Ibrahim

Alustath Journal for Human and Social Sciences

Stylistic analysis implies analyzing a poem from the linguistic as well as critical point of view. While the former leads to a better understanding of the devices used and the construction of the poem, the latter enables one to look at the poem from a critical angle. Together, one gets a complete and comprehensive picture of the poem. In stylistics, it is possible to look at a poem from the point of view of graphology, morphology, phonology and lexico-syntactic level. In this paper, the poem “the Snake’ by D. H. Lawrence has been analysed stylistically. It helps the reader to …

We conducted individual semistructured interviews with 21 international doctoral students attending a large research-intensive university in the Southeast. Most participants were assigned to an interim advisor, but the data revealed concerning differences in the type of advising experiences and support based on …

Achieving The Shot-Noise Limit Using Experimental Multi-Shot Digital Holography Data, Douglas E. Thornton, Cameron J. Radosevich, Samuel Horst, Mark F. Spencer

Faculty Publications

In this paper, we achieve the shot-noise limit using straightforward image-post-processing techniques with experimental multi-shot digital holography data (i.e., off-axis data composed of multiple noise and speckle realizations). First, we quantify the effects of frame subtraction (of the mean reference-only frame and the mean signal-only frame from the digital-hologram frames), which boosts the signal-to-noise ratio (SNR) of the baseline dataset with a gain of 2.4 dB. Next, we quantify the effects of frame averaging, both with and without the frame subtraction. We show that even though the frame averaging boosts the SNR by itself, the frame subtraction and the stability …

2020-Current year OA Pubs

BACKGROUND: We planned an observational study to assess obstetric anesthesia services nationwide. We aimed to assess the effect of the anesthesia workload/workforce ratio on quality and safety outcomes of obstetric anesthesia care.

METHODS: Observers prospectively collected data from labor units over 72 h (Wednesday, Thursday and Friday). Independent variables were workload (WL) and workforce (WF). WL was assessed by the Obstetric Anesthesia Activity Index (OAAI), which is the estimated time in a 24-h period spent on epidurals and all cesarean deliveries. Workforce (WF) was assessed by the number of anesthesiologists dedicated to the labor ward per week. Dependent variables were …

The Characteristics Of Atmospheric Particles And Metal Elements During Winter In Beijing: Size Distribution, Source Analysis, And Environmental Risk Assessment, Minkang Zhi, X Zhang, K Zhang, Simon J. Ussher, Wenli Lv, Jie Li, Jian Gao, Yuqian Luo, Fan Meng

School of Geography, Earth and Environmental Sciences

In order to investigate the pollution characteristics of size-segregated particles and metal elements (MEs) after the Chinese Air Pollution Prevention Action Plan was released in 2013, an intensive field campaign was conducted in the suburban area of Chaoyang District, Beijing in winter 2016. The size distributions of particle mass concentrations were bimodal, with the first peak in the fine fraction (0.4–2.1 µm) and the second peak in the coarse fraction (3.3–5.8 µm). Moreover, the proportion of fine particles increased and the proportion of coarse particles decreased as the pollution level was more elevated. It was found that the composition of …

Effects Of Caffeine On Exercise Duration, Critical Velocity, And Ratings Of Perceived Exertion During Repeated-Sprint Exercise In Physically Active Men, Jesse A. Stein, Heath Gasier, Blake Goodman, Melitza Ramirez, Blanca Delatorre, Cassandra Beattie, Thomas J. Barstow, Katie Heinrich

International Journal of Exercise Science

International Journal of Exercise Science 14(2): 435-445, 2021. Caffeine improves short-to-moderate distance running performance, but the effect of caffeine on repeated sprints are equivocal. This research determined if caffeine improved exercise tolerance during repeated-sprint exercise. iCV is a running velocity that distinguishes intermittent running velocities (velocities ≤ iCV) that are sustainable from those resulting in a predictable time to exhaustion (velocities > iCV). Seven physically active men (age = 21.6 ± 1.5 years, body mass = 72.8 ± 5.1 kg, VO_2max = 56.9 ± 9.8 mL/kg/min) ingested caffeine (5 mg/kg) or placebo (crossover design) 60 min prior to an intermittent …

Trans-Atlantic Interrogation: Fabienne Pasquet’S La Deuxième Mort De Toussaint Louverture, Mariana F. Past

CLCWeb: Comparative Literature and Culture

In “Trans-Atlantic Interrogation: Fabienne Pasquet’s La deuxième mort de Toussaint Louverture,” Mariana Past situates the Haitian-Swiss novelist’s understudied narrative within the context of Caribbean letters and the Haitian literary tradition, then discusses the broader, intertextual implications of Toussaint Louverture’s “second” death for Haiti and the trans-Atlantic world. To what end does Pasquet deploy the aged ghost of a Haitian revolutionary icon being invoked by German Romantic writer Heinrich von Kleist in the Fort de Joux castle-cum-prison within France’s remote, mountainous Jura region? What is at stake when the diasporic writer reincarnates a legendary German poet as protagonist, placing him …

Hanay Geiogamah’S Body Indian And Foghorn As “Plays With A Purpose”, Danica Čerče

CLCWeb: Comparative Literature and Culture

In her article, “Hanay Geiogamah’s Body Indian and Foghorn as ‘Plays with a Purpose,’” written against the backdrop of critical whiteness studies, Danica Čerče discusses how Geiogamah’s theatrical rhetoric intervenes in the assumptions about whiteness as a static, privilege-granting category and system of dominance. By focusing on various techniques and strategies mobilized to define and affirm Native Americans’ authentic rather than imposed identities, the article shows that humor is one of the prime textual devices in Geiogamah’s plays to renegotiate what Walter Mignolo calls “the racist structure of power.”

Problems With Perceptual And Cognitive Idiosyncrasies In Li Wenjun’S Translation Of The Benjy Section Of Faulkner's The Sound And The Fury, Aaron L. Moore

CLCWeb: Comparative Literature and Culture

In his article “Problems with Perceptual and Cognitive Idiosyncrasies in Li Wenjun’s Translation of the Benjy Section of Faulkner’s The Sound and the Fury,” Aaron Lee Moore conducts a close explication of a 2014 English-Chinese edition of part of The Sound and the Fury. Li Wenjun’s translation of the Benjy section of The Sound and the Fury is certainly admirable in its graceful rendering of Faulkner’s complex, idiosyncratic prose style into accessible Chinese—and particularly laudable in its meticulous tracking of the a-chronological sequence of Benjy’s stream of consciousness narrative. However, problems arise in the translation due to an …

Retrieval Practice Consistently Benefits Student Learning: A Systematic Review Of Applied Research In Schools And Classrooms, Pooja K. Agarwal, Ludmila D. Nunes, Janell R. Blunt

Faculty Works

Given the growing interest in retrieval practice among educators, it is valuable to know when retrieval practice does and does not improve student learning—particularly for educators who have limited classroom time and resources. In this literature review, we developed a narrow operational definition for “classroom research” compared to previous reviews of the literature. We screened nearly 2,000 abstracts and systematically coded 50 experiments to establish a clearer picture of benefits from retrieval practice in real world educational settings. Our review yielded 49 effect sizes and a total n = 5,374, the majority of which (57%) revealed medium or large benefits …

Surrogacy Among Filipinos Who Have Struggled With Infertility: A Discourse Analysis, Gabrielle Marie A. Liamzon, Andrea Mari P. Santos, Marie Ashley G. Tamayo, Ma. Elizabeth J. Macapagal

Psychology Department Faculty Publications

Surrogacy continues to be practiced to address infertility in the Philippines; however, discussions on the method are sparse, given its limited accessibility and morally questionable procedures that may concern potential parents in a developing country. Using discourse analysis, the researchers interviewed ten (10) Filipino Roman Catholics who were struggling with infertility, to uncover how they construct the idea of surrogacy. The study shows the discourses on surrogacy are often approached in a detached manner, where potential parents describe the method as a last choice or one that is never considered. They articulate this position by highlighting the emotional factors surrogacy …

Discretion And Disparity In Federal Detention, Stephanie Holmes Didwania

Northwestern University Law Review

The uniquely American phenomenon of mass incarceration plagues the pretrial space. People awaiting trial make up roughly 20% of those held in criminal custody in the United States. Largely overlooked by bail-reform advocates, pretrial detention in the federal criminal system presents a puzzle. The federal system detains defendants at a much higher rate than the states—more than 60% of U.S. citizen-defendants were detained pending trial by federal courts last year. But federal defendants virtually never fail to appear in court, and they are rarely arrested for new crimes while on pretrial release. And unlike state court systems, cash bail is …

A Pathway For Citizen Science Data To Inform Policy: A Case Study Using Ebird Data For Defining Low-Risk Collision Areas For Wind Energy Development, Viviana Ruiz-Gutierrez, Emily R. Bjerre, Mark C. Otto, Guthrie S. Zimmerman, Brian A. Millsap, Daniel Fink, Erica F. Stuber, Matthew Strimas-Mackey, Orin J. Robinson

Wildland Resources Faculty Publications

1. The research and conservation community has successfully harnessed the wealth of ecological knowledge found in unprecedented volumes of citizen science (CS) data world-wide. However, few examples exist of the use of CS data to directly inform policy.

2. Current examples of applications of CS data mainly stem from programs that are restricted in scope (e.g. defined protocols, restricted sampling time frame), and the potential use of unrestricted CS data to inform policy remains largely untapped.

3. Here, we make a call for moving beyond questioning the reliability of CS data and present a case study of how the US …
