Deploying A Task-Based Runtime System On Raspberry Pi Clusters, Nikunj Gupta, Steve R. Brandt, Bibek Wagle, Nanmiao Wu, Alireza Kheirkhahan, Patrick Diehl, Felix W. Baumann, Hartmut Kaiser

Faculty Publications

Arm® technology is becoming increasingly important in HPC. Recently, Fugaku, an Arm®-based system, was awarded the number one place in the Top500 list. Raspberry Pis provide an inexpensive platform to become familiar with this architecture. However, Pis can also be useful on their own. Here we describe our efforts to configure and benchmark the use of a Raspberry Pi cluster with the HPX/Phylanx platform (normally intended for use with HPC applications) and document the lessons we learned. First, we highlight the required changes in the configuration of the Pi to gain performance. Second, we explore how limited memory bandwidth limits …

Towards A Scalable And Distributed Infrastructure For Deep Learning Applications, Bita Hasheminezhad, Shahrzad Shirzad, Nanmiao Wu, Patrick Diehl, Hannes Schulz, Hartmut Kaiser

Faculty Publications

Although recent scaling up approaches to train deep neural networks have proven to be effective, the computational intensity of large and complex models, as well as the availability of large-scale datasets require deep learning frameworks to utilize scaling out techniques. Parallelization approaches and distribution requirements are not considered in the primary designs of most available distributed deep learning frameworks and most of them still are not able to perform effective and efficient fine-grained inter-node communication. We present Phylanx that has the potential to alleviate these shortcomings. Phylanx presents a productivity-oriented frontend where user Python code is translated to a futurized …

The Case Against Prosecuting Refugees, Evan J. Criddle

Faculty Publications

Within the past several years, the U.S. Department of Justice has pledged to prosecute asylum-seekers who enter the United States outside an official port of entry without inspection. This practice has contributed to mass incarceration and family separation at the U.S.–Mexico border, and it has prevented bona fide refugees from accessing relief in immigration court. Yet, federal judges have taken refugee prosecution in stride, assuming that refugees, like other foreign migrants, are subject to the full force of American criminal justice if they skirt domestic border controls. This assumption is gravely mistaken.

Framing The Second Amendment: Gun Rights, Civil Rights And Civil Liberties, Timothy Zick

Faculty Publications

Gun rights proponents and gun control advocates have devoted significant energy to framing the constitutional right to keep and bear arms. In constitutional discourse, advocates and commentators have referred to the Second Amendment as a "collective, ""civic republican," "individual," and 'fundamental" right. Gun rights advocates have defended the right to keep and bear arms on "law and order" grounds, while gun control proponents have urged regulation based on "public health, " "human rights, " and other concerns. These frames and concepts have significantly influenced how the right to keep and bear arms has been debated, interpreted, and enforced. This Article …

The Remand Power And The Supreme Court's Role, Aaron-Andrew P. Bruhl

Faculty Publications

"Reversed and remanded." Or "vacated and remanded." These familiar words, often found at the end of an appellate decision, emphasize that an appellate court's conclusion that the lower court erred generally does not end the litigation. The power to remand for further proceedings rather than wrap up a case is useful for appellate courts because they may lack the institutional competence to bring the case to a final resolution (as when new factual findings are necessary) or lack an interest in the fact-specific work of applying a newly announced legal standard to the particular circumstances at hand. The modern Supreme …

“It's Hard To See How These Would Be Harmful To Kids”: Public Library Staff Perceptions Of Child Development And Drag Queen Storytimes, Sarah Barriage, Vanessa Kitzie, Diana Floegel, Shannon M. Oltmann

Faculty Publications

This paper reports preliminary results of a survey of 458 US public library staff members regarding their perceptions of drag queen storytimes (DQS) and the ways in which these storytimes influence child development. The majority of respondents from libraries that have hosted at least one DQS agreed that DQS support healthy child development and positively influence children’s understanding of gender and/or sexuality, while respondents from libraries that have not hosted DQS were more likely to disagree or report being undecided. Specific ways in which respondents perceive DQS to influence child development are also analyzed.

Establishing The Foundations To Measure Organizational Agility For Military Organizations, Jeremy R. Geiger, John J. Elshaw, David R. Jacques

Faculty Publications

There is an ongoing demand for organizations to become more agile in order to prosper amongst their competitors. Many military organizations have declared a renewed focus towards organizational agility. The goal of this research is to isolate the variables needed to measure organizational agility (OA) in military organizations, allowing for the future development of a suitable method to measure OA without the need to interact with outside organizations. This article begins by providing a suitable and formal definition of organizational agility by exploring and analyzing relevant scholarly literature on the subject. Related terms, such as organizational resiliency, flexibility, robustness, versatility, …

Legendre G-Array Pairs And The Theoretical Unification Of Several G-Array Families, K. T. Arasu, Dursun A. Bulutoglu, J. R. Hollon

Faculty Publications

We investigate how Legendre G-array pairs are related to several different perfect binary G-array families. In particular we study the relations between Legendre G-array pairs, Sidelnikov-Lempel-Cohn-Eastman ℤ_q−1-arrays, Yamada-Pott G-array pairs, Ding-Helleseth-Martinsen ℤ₂×ℤ^m_p-arrays, Yamada ℤ_(q−1)/2-arrays, Szekeres ℤ^m_p-array pairs, Paley ℤ^m_p-array pairs, and Baumert ℤ^m1_p1×ℤ^m2_p2-array pairs. Our work also solves one of the two open problems posed in Ding~[J. Combin. Des. 16 (2008), 164-171]. Moreover, we provide several computer search based existence and non-existence results regarding Legendre ℤ_n-array pairs. …

Writing Standards-Based Lesson Plans To Standards For Technological And Engineering Literacy, Scott Bartholomew, Thomas Loveland, Vanessa Santana

Faculty Publications

While written lesson plans may seem like a lot of work, with little purpose or benefit to new teachers, a well-written lesson plan is quite valuable for many reasons. The process of writing lesson plans at the beginning of one’s teaching career can be very time-consuming (Arnett-Hartwick and Cannon, 2019); however, the development of sequenced lessons that result in effective learning must be organized and articulate, not done haphazardly. Designing a lesson through a written document can help a teacher see the pattern, flow, and implications of a lesson and how it will help all students; this can be especially …

Financial Socialization: A Decade In Review, Ashley B. Lebaron, Heather H. Kelly

Faculty Publications

The financial socialization individuals receive is associated not only with their future financial wellbeing but also relational, mental, and physical wellbeing. This paper is a review of the literature on financial socialization, especially papers published between 2010 and 2019 in the Journal of Family and Economic Issues. We first review family financial socialization theory and then review empirical documentation for the theory, organized by (a) family socialization processes (e.g., parent financial modeling, parent-child financial discussion, and experiential learning as three primary methods of financial socialization) and (b) financial socialization outcomes (e.g., financial attitudes, financial knowledge, financial behaviors, and financial wellbeing). …

William Clark, The Fur Trade, And Indian Affairs, Jay H. Buckley

Faculty Publications

There are so many things that are admirable about William Clark. Sometimes I shudder to think what the great expedition would have been if Clark had declined Lewis’ offer to share in what Clark called “the dangers, difficulties, and fatigues” of the journey. Without wishing to denigrate the possible contributions of Moses Hooke, I believe that the expedition would have been a much less successful enterprise if Clark had remained at the Falls of the Ohio when Lewis ventured into the unknown in 1803.

Predators As Agents Of Selection And Diversification, Jerald B. Johnson, Mark C. Belk

Faculty Publications

Predation is ubiquitous in nature and can be an important component of both ecological and evolutionary interactions. One of the most striking features of predators is how often they cause evolutionary diversification in natural systems. Here, we review several ways that this can occur, exploring empirical evidence and suggesting promising areas for future work. We also introduce several papers recently accepted in Diversity that demonstrate just how important and varied predation can be as an agent of natural selection. We conclude that there is still much to be done in this field, especially in areas where multiple predator species prey …

Patterning A Leaf By Establishing Polarities, Darren Manuela, Mingli Xu

Faculty Publications

Leaves are the major organ for photosynthesis in most land plants, and leaf structure is optimized for the maximum capture of sunlight and gas exchange. Three polarity axes, the adaxial–abaxial axis, the proximal-distal axis, and the medial-lateral axis are established during leaf development to give rise to a flattened lamina with a large area for photosynthesis and blades that are extended on petioles for maximum sunlight. Adaxial cells are elongated, tightly packed cells with many chloroplasts, and their fate is specified by HD-ZIP III and related factors. Abaxial cells are rounder and loosely packed cells and their fate is established …

A Numerical Investigation Of Salinity Variations In The Barataria Estuary, Louisiana In Connection With The Mississippi River And Restoration Activities, Yanda Ou, Z. George Xue, Chunyan Li, Kehui Xu, John R. White, Samuel J. Bentley, Zhengchen Zang

Faculty Publications

© 2020 Elsevier Ltd A three-dimensional numerical model was applied to the Barataria Estuary in the Northern Gulf of Mexico to study its salinity variations as well as the impacts from the Mississippi River discharges and proposed river diversions. Model-observation comparison showed that the model was able to reproduce the hydrodynamic fields on subtidal to seasonal time scales. Salinity in the Barataria Estuary was high in fall and low in summer, with a greater variability in the lower estuary than the upper estuary. While salinity in the upper estuary was controlled by discharges from a local freshwater diversion, salinity in …

Simulating Hydrological Connectivity And Water Age Within A Coastal Deltaic Floodplain Of The Mississippi River Delta, Alexandra Christensen, Robert R. Twilley, Clinton S. Willson, Edward Castañeda-Moya

Faculty Publications

Located at the mouth of large rivers, coastal deltaic floodplains are important ecosystems for trapping sediment and removing excess nitrogen introduced to the river through agricultural and urban runoff. Hydrological connectivity (the percent of river channel water interacting with floodplain wetlands), water age (the time elapsed since water entered the system via the main river channel) and water temperature have strong impacts on the biogeochemical processes controlling the fate of sediment and nutrients at continental margins. A Delft3D hydrodynamic model was used to explore the role of river and tide forcings, hydrogeomorphology, and vegetation roughness on hydrological connectivity, water age, …

Building Capacity In Dissemination And Implementation Science: A Systematic Review Of The Academic Literature On Teaching And Training Initiatives, Rachel E. Davis, Danielle D'Lima

Faculty Publications

BACKGROUND: The field of dissemination and implementation (D&I) science has grown significantly over recent years. Alongside this, an increased demand for training in D&I from researchers and implementers has been seen. Research describing and evaluating D&I training opportunities, referred to here as 'capacity building initiatives' (CBIs), can help provide an understanding of different methods of training as well as training successes and challenges. However, to gain a more detailed understanding of the evidence-base and how D&I CBIs are being reported in publications, a field-wide examination of the academic literature is required. METHODS: Systematic review to identify the type and range …

Molecular Motions Of Acetonitrile Molecules In The Solvation Shell Of Lithium Ions, Xiaobing Chen, Daniel G. Kuroda

Faculty Publications

© 2020 Author(s). Lithium ion solutions in organic solvents have become ubiquitous because of their use in energy storage technologies. The widespread use of lithium salts has prompted a large scientific interest in elucidating the molecular mechanisms, giving rise to their macroscopic properties. Due to the complexity of these molecular systems, only few studies have been able to unravel the molecular motions and underlying mechanisms of the lithium ion (Li+) solvation shell. Lately, the atomistic motions of these systems have become somewhat available via experiments using ultrafast laser spectroscopies, such as two-dimensional infrared spectroscopy. However, the molecular mechanism behind the …

Search For A Dark Leptophilic Scalar In E + E − Collisions, J. P. Lees, V. Poireau, V. Tisserand, E. Grauges, A. Palano, G. Eigen, D. N. Brown, Yu. G. Kolomensky, M. Fritsch, H. Koch, T.

Faculty Publications

Many scenarios of physics beyond the standard model predict the existence of new gauge singlets, which might be substantially lighter than the weak scale. The experimental constraints on additional scalars with masses in the MeV to GeV range could be significantly weakened if they interact predominantly with leptons rather than quarks. At an e⁺e⁻ collider, such a leptophilic scalar (_ϕL) would be produced predominantly through radiation from a τ lepton. We report herein a search for e⁺e⁻→ τ⁺τ⁻_ϕL, _ϕL → l⁺l⁻ (l = …

Using Reactive Dissipative Particle Dynamics To Understand Local Shape Manipulation Of Polymer Vesicles, Qinyu Zhu, Timothy R. Scott, Douglas R. Tree

Faculty Publications

Biological cells have long been of interest to researchers due to their capacity to actively control their shape. Accordingly, there is significant interest in generating simplified synthetic protocells that can alter their shape based on an externally or internally generated stimulus. To date, most progress has been made towards controlling the global shape of a protocell, whereas less is known about generating a local shape change. Here, we seek to better understand the possible mechanisms for producing local morphological changes in a popular protocell system, the block copolymer vesicle. Accordingly, we have combined Dissipative Particle Dynamics (DPD) and the Split …

Association Of Patient-Centered Medical Home Designation And Quality Indicators Within Hrsa-Funded Community Health Center Delivery Sites, Nathaniel Bell, Rebecca Wilkerson, Kathy Mayfield-Smith, Ana Lòpez-De Fede

Faculty Publications

BACKGROUND: Patient-Centered Medical Home (PCMH) adoption is an important strategy to help improve primary care quality within Health Resources and Service Administration (HRSA) community health centers (CHC), but evidence of its effect thus far remains mixed. A limitation of previous evaluations has been the inability to account for the proportion of CHC delivery sites that are designated medical homes.

METHODS: Retrospective cross-sectional study using HRSA Uniform Data System (UDS) and certification files from the National Committee for Quality Assurance (NCQA) and the Joint Commission (JC). Datasets were linked through geocoding and an approximate string-matching algorithm. Predicted probability scores were …

Mechanisms Of Asymmetric Membrane Formation In Nonsolvent-Induced Phase Separation, Jan Ulric Garcia, Tatsuhiro Iwama, Eva Y. Chan, Douglas R. Tree, Kris T. Delaney, Glenn H. Fredrickson

Faculty Publications

We report the first simulations of nonsolvent-induced phase separation (NIPS) that predict membrane microstructures with graded asymmetric pore size distribution. In NIPS, a polymer solution film is immersed in a nonsolvent bath, enriching the film in nonsolvent, and leading to phase separation that forms a solid polymer-rich membrane matrix and polymer-poor membrane pores. We demonstrate how mass-transfer-induced spinodal decomposition, thermal fluctuations, and glass-transition dynamics—implemented with mobility contrast between the polymer-rich and polymer-poor phases—are essential to the formation of asymmetric membrane microstructures. Specifically, we show that the competition between the propagation of the phase-separation and glass-transition fronts determines the degree of …

Why Parents Say No To Having Their Children Vaccinated Against Measles: Social Determinants Of Parental Perceptions To Vaccine Hesitancy, M. Lelinneth B. Novilla, Michael C. Goates, Mallory Showalter, Lynneth Kirsten B. Novilla, Tyler Leffler, Russell B. Doria, Michael T. Dang, Katelyn Aldridge

Faculty Publications

Background: Although national and state immunization coverage rates are high, the resurgence of measles points to local pockets of under-vaccination that correspond with higher non-medical exemptions and lower parental confidence on vaccines. The reported geographic clustering of vaccine hesitancy, particularly against MMR, points to social drivers that shape parental perceptions and decisions on immunization.

Objectives. To analyze: (1) why parents delay or refuse vaccination, specifically MMR; (2) social context of vaccine hesitancy and perceived reliable sources of vaccine information between vaccine-hesitant and vaccine-compliant parents/guardians; (3) role of families in countering vaccine hesitancy; (4) strategies at the public health, primary care, …
