Evidence Of Metasomatism In The Interior Of Vesta, Ai Cheng Zhang, Noriyuki Kawasaki, Huiming Bao, Jia Liu, Liping Qin, Minami Kuroda, Jian Feng Gao, Li Hui Chen, Ye He, Naoya Sakamoto, Hisayoshi Yurimoto

Faculty Publications

© 2020, The Author(s). Diogenites are a group of meteorites that are derived from the interior of the largest protoplanet Vesta. They provide a unique opportunity to understanding together the internal structure and dynamic evolution of this protoplanet. Northwest Africa (NWA) 8321 was suggested to be an unbrecciated noritic diogenite meteorite, which is confirmed by our oxygen and chromium isotopic data. Here, we find that olivine in this sample has been partly replaced by orthopyroxene, troilite, and minor metal. The replacement texture of olivine is unambiguous evidence of sulfur-involved metasomatism in the interior of Vesta. The presence of such replacement …

Engaging Empirical Dynamic Modeling To Detect Intrusions In Cyber-Physical Systems, David R. Crow, Scott R. Graham, Brett J. Borghetti, Patrick J. Sweeney

Faculty Publications

Modern cyber-physical systems require effective intrusion detection systems to ensure adequate critical infrastructure protection. Developing an intrusion detection capability requires an understanding of the behavior of a cyber-physical system and causality of its components. Such an understanding enables the characterization of normal behavior and the identification and reporting of anomalous behavior. This chapter explores a relatively new time series analysis technique, empirical dynamic modeling, that can contribute to system understanding. Specifically, it examines if the technique can adequately describe causality in cyber-physical systems and provides insights into it serving as a foundation for intrusion detection.

Faculty Publications

In the current era of rapid climate change, accurate characterization of climate-relevant gas dynamics-namely production, consumption, and net emissions-is required for all biomes, especially those ecosystems most susceptible to the impact of change. Marine environments include regions that act as net sources or sinks for numerous climateactive trace gases including methane (CH4) and nitrous oxide (N2O). The temporal and spatial distributions of CH4 and N2O are controlled by the interaction of complex biogeochemical and physical processes. To evaluate and quantify how these mechanisms affect marine CH4 and N2O cycling requires a combination of traditional scientific disciplines including oceanography, microbiology, and …

Interferences On Aerosol Acidity Quantification Due To Gas-Phase Ammonia Uptake Onto Acidic Sulfate Filter Samples, Benjamin A. Nault, Pedro Campuzano-Jost, Douglas A. Day, Hongyu Guo, Duseong S. Jo, Anne V. Handschy, Demetrios Pagonis, Jason C. Schroder, Melinda K. Schueneman, Michael J. Cubison, Jack E. Dibb, Alma Hodzic, Weiwei Hu, Brett B. Palm, Jose L. Jimenez

Faculty Publications

Measurements of the mass concentration and chemical speciation of aerosols are important to investigate their chemical and physical processing from near emission sources to the most remote regions of the atmosphere. A common method to analyze aerosols is to collect them onto filters and analyze the filters offline; however, biases in some chemical components are possible due to changes in the accumulated particles during the handling of the samples. Any biases would impact the measured chemical composition, which in turn affects our understanding of numerous physicochemical processes and aerosol radiative properties. We show, using filters collected onboard the NASA DC-8 …

Mapping Flat, Deep, And Slow: On The 'Spirit Of Place' In New Cinema History, Jeffrey Klenotic

Faculty Publications

This essay engages in a creative, heuristic, and reflexive consideration of the ‘localities’ of cinema audiences by exploring New Cinema History as a place. New Cinema History is conceptualised as a place continually produced in and through its interactions with the heterogeneous multiplicities of situated audiences and experiences of cinema that form the topoi of its landscape of inquiry. In reflecting on how this placialised landscape has been and might be represented, I argue that New Cinema History’s ‘spirit of place’ is most productive when rendered within a ‘splatial’ framework that draws upon practices of flat, deep, and slow mapping …

Interplay Of Changing Irrigation Technologies And Water Reuse: Example From The Upper Snake River Basin, Idaho, Usa, Shan Zuidema, Danielle S. Grogan, Alexander Prusevich, Richard B. Lammers, Sarah Gilmore, Paula Williams

Faculty Publications

Careful allotment of water resources for irrigation is critical for ensuring the resiliency of agriculture in semiarid regions, and modernizing irrigation technology to minimize inefficient water losses is an important tool for farmers and agricultural economies. While modernizing irrigation technology can achieve reductions in the nonbeneficial use of water, such as bare soil evaporation and nonconsumptive losses, water returned to the landscape is also reduced, often eliminating flow paths that other users rely on. In basins using a combination of surface and groundwater, replenishing aquifer storage by the managed aquifer recharge (MAR) of seasonally available water can mitigate the aquifer …

Two Kinds Of Polar Knowledge, Lawrence C. Hamilton

Faculty Publications

Outreach and communication with the public have substantial value in polar research, in which studies often find changes of global importance that are happening far out of sight from the majority of people living at lower latitudes. Seeking evidence on the effectiveness of outreach programs, the U.S. National Science Foundation sponsored large-scale survey assessments before and after the International Polar Year in 2007/2008. Polar-knowledge questions have subsequently been tested and refined through other nationwide and regional surveys. More than a decade of such work has established that basic but fairly specific knowledge questions, with all answer choices sounding plausible but …

Service Gifts, Collective Social Connection And Reciprocity, Yihui (Elina) Tang, Christian Hinsch, Donald J. Lund, Husni Kharouf

Faculty Publications

Purpose: This study aims to investigate the process of service gifting (i.e. unexpected upgrades or benefits) and examine why service gifts do not always result in firm-beneficial reciprocal behaviors from consumers. Design/methodology/approach: Through a series of three studies including both scenario-based and game-theory-based experiments, this research proposes and empirically validates a conceptual model that examines the effect of service gifts on firm-beneficial reciprocal behaviors, and the role of collective social connection and norm of positive reciprocity (NPR) in this process. Findings: The findings of this research show that the consumer’s feelings of collective social connection mediate the link between the …

Facilitating A Path To New Teacher Certification Amid The Covid-19 Pandemic: Unpacking States’ Unchanged-New Flex” Guidelines, Laura E. Slay, Jacqueline Riley, Karyn E. Miller

Faculty Publications

In the United States, amid the COVID-19 pandemic, schools and testing centers were forced to close on-site locations. With teacher candidates no longer able to complete clinical teaching or take certification exams in person, states created new recommendations for facilitating a pathway to teacher certification. Specifically, 19 states provided guidelines that allowed educator preparation programs (EPPs) flexibility in how teacher candidates completed existing certification requirements. By analyzing summaries of these states’ guidelines, themes of time, technology, flexibility/nonflexibility, and EPPs emerged. Using a comprehensive lens, this brief examines the role and implications of each of these themes in teacher certification during …

Parsing The Impact Of Alice And The Peg, Colleen Chien, Nicholas Halkowski, Maria He, Rodney Swartz

Faculty Publications

Almost two years have passed since the USPTO issued its January 2019 Patent Eligibility Guidance (PEG), itself a response to the Supreme Court’s Alice decision, and what many perceived as its destabilizing impact on the certainty of patent prosecutions. Leveraging new data releases, we report on trends in prosecution following the USPTO’s PEG and the Guidance on 112, finding 1) a decline in subject matter rejections and stabilization of subject matter appeals, 2) no discernable increase in 112 rejections, 3) no evidence that small entities were being left behind in Alice-impacted art units by forum shopping by large entities, …

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

Faculty Publications

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 the nominal Caribbean candelabrum coral Eunicea flexuosa. Previous analyses based on a handful of markers could not distinguish between models of genetic exchange …

A Theory Of Multiformat Communication: Mechanisms, Dynamics, And Strategies, Jordan W. Moffett, Judith Anne Garretson Folse, Robert W. Palmatier

Faculty Publications

Extant communication theories predate the explosion of digital formats and technological advances such as virtual reality, which likely explains their predominant focus on traditional and format-level (e.g., face-to-face, email) rather than digital or characteristic-level (e.g., visual cues, synchronicity) design decisions. Firms thus lack insights into how to create and use emerging digital formats, individually or synergistically. To establish a holistic framework of bilateral multiformat communication for relationship marketing, this article reviews communication theory to establish a foundation for understanding multiformat communication and to identify any gaps (e.g., AI agents, simulated cues). The authors then review bilateral communication research in light …

Potential Link Between Compromised Air Quality And Transmission Of The Novel Corona Virus (Sars-Cov-2) In Affected Areas, M. G. Manoj, M. K. Satheesh Kumar, K. T. Valsaraj, C. Sivan, Soumya K. Vijayan

Faculty Publications

The emergence of a novel human corona virus disease (COVID-19) has been declared as a pandemic by the World Health Organization. One of the mechanisms of airborne transmission of the severe acute respiratory syndrome corona virus (SARS-CoV-2) amid humans is through direct ejection of droplets via sneezing, coughing and vocalizing. Nevertheless, there are ample evidences of the persistence of infectious viruses on inanimate surfaces for several hours to a few days. Through a critical review of the current literature and a preliminary analysis of the link between SARS-CoV-2 transmission and air pollution in the affected regions, we offer a perspective …

Aroma, Quality, And Consumer Mindsets For Shelf-Stable Rice Thermally Processed By Reciprocal Agitation, William R. Dixon, Blanca E. Morales-Contreras, Manoch Kongchum, Zhimin Xu, Dustin Harrell, Howard R. Moskowitz, Louise Wicker

Faculty Publications

Food engineering, food chemistry, and consumer segmentation were used to evaluate ready-to-eat rice. The aromatic Louisiana Clearfield Jazzman (CJ) and Thai Jasmine (TJ), and a non-aromatic parboiled (PB) rice were hydrated during the first 10 min of processing with reciprocal agitation followed by static retort processing. The aroma compound, 2-Acetyl-1-pyrroline (2-AP) was more heat-stable in CJ than TJ rice but decreased 15-fold compared to the rice cooker method. Pareto analysis indicated that rice type and agitation had the main effect on amylose and total starch and chroma and hue. Color differences of rice agitated during hydration and between rice cooker …

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

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 …

Towards Distributed Software Resilience In Asynchronous Many-Task Programming Models, Nikunj Gupta, Jackson R. Mayo, Adrian S. Lemoine, Hartmut Kaiser

Faculty Publications

Exceptions and errors occurring within mission critical applications due to hardware failures have a high cost. With the emerging Next Generation Platforms (NGPs), the rate of hardware failures will likely increase. Therefore, designing our applications to be resilient is a critical concern in order to retain the reliability of results while meeting the constraints on power budgets. In this paper, we discuss software resilience in AMTs at both local and distributed scale. We choose HPX to prototype our resiliency designs. We implement two resiliency APIs that we expose to the application developers, namely task replication and task replay. Task replication …

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 …
