Entanglement-Assisted Private Communication Over Quantum Broadcast Channels, Haoyu Qi, Kunal Sharma, Mark M. Wilde Aug 2018

Entanglement-Assisted Private Communication Over Quantum Broadcast Channels, Haoyu Qi, Kunal Sharma, Mark M. Wilde

Faculty Publications

We consider entanglement-assisted (EA) private communication over a quantum broadcast channel, in which there is a single sender and multiple receivers. We divide the receivers into two sets: the decoding set and the malicious set. The decoding set and the malicious set can either be disjoint or can have a finite intersection. For simplicity, we say that a single party Bob has access to the decoding set and another party Eve has access to the malicious set, and both Eve and Bob have access to the pre-shared entanglement with Alice. The goal of the task is for Alice to communicate …

Continuous-Discrete Sequential Observers Under Sampling And Input Delays, Frederic Mazenc, Michael Malisoff Aug 2018

Continuous-Discrete Sequential Observers Under Sampling And Input Delays, Frederic Mazenc, Michael Malisoff

Faculty Publications

We provide continuous-discrete sequential observers for linear systems with input delays, sampling in the controls and in the outputs, and uncertainties. We also include uncertainties and delays in the output. Our observer allows arbitrarily long constant delays in the input and in the output, and can be used to provide input-to-state stabilizing controllers under uncertain sampled outputs, sampling in the control, and arbitrarily long input and output delays. Since our control does not contain distributed terms, this paper is an extension of the recent prediction technique based on subsequential observers. This provides a useful alternative to existing methods that contained …

Dietary Inflammatory Index And Biomarkers Of Lipoprotein Metabolism, Inflammation And Glucose Homeostasis In Adults, Catherine Phillips, Nitin Shivappa, James R. Hébert, Ivan Perry Aug 2018

Dietary Inflammatory Index And Biomarkers Of Lipoprotein Metabolism, Inflammation And Glucose Homeostasis In Adults, Catherine Phillips, Nitin Shivappa, James R. Hébert, Ivan Perry

Faculty Publications

Accumulating evidence identifies diet and inflammation as potential mechanisms contributing to cardiometabolic risk. However, inconsistent reports regarding dietary inflammatory potential, biomarkers of cardiometabolic health and metabolic syndrome (MetS) risk exist. Our objective was to examine the relationships between a food frequency questionnaire (FFQ)-derived dietary inflammatory index (DII®), biomarkers of lipoprotein metabolism, inflammation and glucose homeostasis and MetS risk in a cross-sectional sample of 1992 adults. Energy-adjusted DII (E-DII) scores derived from an FFQ were calculated. Lipoprotein particle size and subclass concentrations were measured using nuclear magnetic resonance (NMR) spectroscopy. Serum acute-phase reactants, adipocytokines, pro-inflammatory cytokines and white blood cell (WBC) …

Cyber Anomaly Detection: Using Tabulated Vectors And Embedded Analytics For Efficient Data Mining, Robert J. Gutierrez, Kenneth W. Bauer, Bradley C. Boehmke, Cade M. Saie, Trevor J. Bihl Aug 2018

Cyber Anomaly Detection: Using Tabulated Vectors And Embedded Analytics For Efficient Data Mining, Robert J. Gutierrez, Kenneth W. Bauer, Bradley C. Boehmke, Cade M. Saie, Trevor J. Bihl

Faculty Publications

Firewalls, especially at large organizations, process high velocity internet traffic and flag suspicious events and activities. Flagged events can be benign, such as misconfigured routers, or malignant, such as a hacker trying to gain access to a specific computer. Confounding this is that flagged events are not always obvious in their danger and the high velocity nature of the problem. Current work in firewall log analysis is manual intensive and involves manpower hours to find events to investigate. This is predominantly achieved by manually sorting firewall and intrusion detection/prevention system log data. This work aims to improve the ability of …

Multi-Pred: A Software Module For Predictive Modeling Of Coupled Multi-Physics Systems, Dan Gabriel Cacuci, Ruixian Fang, Madalina C. Badea Aug 2018

Multi-Pred: A Software Module For Predictive Modeling Of Coupled Multi-Physics Systems, Dan Gabriel Cacuci, Ruixian Fang, Madalina C. Badea

Faculty Publications

The software module MULTI-PRED implements the methodology for predictive modeling of coupled multi-physics systems (PM-CMPS) formulated by Cacuci [Ann. Nucl. Energy, Vol. 70, p, 266 (2014)]. This methodology fully takes into account the coupling terms between the systems but requires only the computational resources that would be needed to perform predictive modeling on each system separately. The PM-CMPS methodology uses the maximum entropy principle to construct an optimal approximation of the unknown a priori distribution based on a priori known mean values and uncertainties characterizing the experimental and computational parameters and results of interest responses called for the multi-physics models …

Role Of Stone-Wales Defects On The Interfacial Interactions Among Graphene, Carbon Nanotubes, And Nylon 6: A First-Principles Study, Sanjiv K. Jha, Michael Roth, Guido Todde, J. Paige Buchanan, Robert D. Moser, Manoj K. Shukla, Gopinath Subramanian Aug 2018

Role Of Stone-Wales Defects On The Interfacial Interactions Among Graphene, Carbon Nanotubes, And Nylon 6: A First-Principles Study, Sanjiv K. Jha, Michael Roth, Guido Todde, J. Paige Buchanan, Robert D. Moser, Manoj K. Shukla, Gopinath Subramanian

Faculty Publications

We investigate computationally the role of Stone-Wales (SW) defects on the interfacial interactions among graphene, carbon nanotubes (CNTs), and Nylon 6 using density functional theory (DFT) and the empirical force-field. Our first-principles DFT calculations were performed using the Quantum ESPRESSO electronic structure code with the highly accurate van der Waals functional (vdW-DF2). Both pristine and SW-defected carbon nanomaterials were investigated. The computed results show that the presence of SW defects on CNTs weakens the CNT-graphene interactions. Our result that CNT-graphene interaction is much stronger than CNT-CNT interaction indicates that graphene would be able to promote the dispersion of CNTs in …

Examining Ec-6 Pre-Service Teachers' Perceptions Of Self-Efficacy In Teaching Mathematics, Tonya D. Jeffery, Lisa D. Hobson, Sarah J. Conoyer, Karen E. Miller, Lesley F. Leach Aug 2018

Examining Ec-6 Pre-Service Teachers' Perceptions Of Self-Efficacy In Teaching Mathematics, Tonya D. Jeffery, Lisa D. Hobson, Sarah J. Conoyer, Karen E. Miller, Lesley F. Leach

Faculty Publications

Mathematics teacher quality has become a major focus in national education reform efforts. In addition, there is an increasing interest in the effectiveness of teacher preparation programs and the undergraduate preparation of elementary mathematics teachers. Empirical evidence suggests that teacher attitudes, behaviors and values, or dispositions, towards teaching have a significant impact on student outcomes. The purpose of this study is to survey juniors and seniors in an undergraduate teacher preparation program to gauge their perceptions of self-efficacy and comfort with teaching mathematics. The results have implications for, and reaffirm concerns about the undergraduate preparation of elementary mathematics teachers.

The Multimodal Interactional Work Of Having Wonderful Ideas, Benedikt Harrer Aug 2018

The Multimodal Interactional Work Of Having Wonderful Ideas, Benedikt Harrer

Faculty Publications

Learning physics is socially organized through interactions with peers and more competent others. Instructors' and peers' assessment of and responsiveness to learners' ideas in the moment is critical for the collaborative construction of knowledge in physics. However, we still know little about how instructors and learners negotiate the value and productiveness of ideas. While to an outsider, some of the ideas physics learners discuss do not seem immediately valuable or productive for the problem being solved, Duckworth encourages us to pursue an 'insider's view' on how a learner experiences their ideas. Building on Duckworth, I pursue an 'insider's view' to …

Fluctuating Hydrodynamics Of Reactive Liquid Mixtures, Changho Kim, Andy. Nonaka, John Bell, Alejandro Garcia, Aleksandar Donev Aug 2018

Fluctuating Hydrodynamics Of Reactive Liquid Mixtures, Changho Kim, Andy. Nonaka, John Bell, Alejandro Garcia, Aleksandar Donev

Faculty Publications

Fluctuating hydrodynamics (FHD) provides a framework for modeling microscopic fluctuations in a manner consistent with statistical mechanics and nonequilibrium thermodynamics. This paper presents an FHD formulation for isothermal reactive incompressible liquid mixtures with stochastic chemistry. Fluctuating multispecies mass diffusion is formulated using a Maxwell–Stefan description without assuming a dilute solution, and momentum dynamics is described by a stochastic Navier–Stokes equation for the fluid velocity. We consider a thermodynamically consistent generalization for the law of mass action for non-dilute mixtures and use it in the chemical master equation (CME) to model reactions as a Poisson process. The FHD approach provides remarkable …

Early Detection Of Fracture Failure In Slm Am Tension Testing With Talbot-Lau Neutron Interferometry, Adam J. Brooks, Hong Yao, Jumao Yuan, Omoefe Kio, Caroline G. Lowery, Henning Markötter, Nikolay Kardjilov, Shengmin Guo, Leslie G. Butler

Faculty Publications

© 2018 Elsevier B.V. Tensile stress in selective laser melted (SLM) stainless steel 316 (SS316) bars was studied with neutron imaging methods for measurement of attenuation, scattering, and diffraction. The hypotheses for stress failure includes modifications to both the grain structure and residual porosity. Neutron Bragg edge imaging showed a change in crystallographic structure and/or texture at a pre-existing fracture, but did not provide evidence for presumptive crack formation. A Talbot-Lau grating-based neutron interferometer yielded better than 100 μm spatial resolution for the attenuation images and was tuned to an autocorrelation scattering length of 1.97 μm for the dark-field (scattering) …

Designing Agricultural Economics And Agribusiness Undergraduate Programs, Jeffrey M. Gillespie, Maria Bampasidou Aug 2018

Designing Agricultural Economics And Agribusiness Undergraduate Programs, Jeffrey M. Gillespie, Maria Bampasidou

Faculty Publications

© 2018 The Author(s). This is an Open Access article, distributed under the terms of the Creative Commons Attribution licence. Agricultural economics and agribusiness (AEAB) programs offer their graduates unique exposure to agricultural markets, policy, and production systems, which differentiates them from business programs. Despite the advantages associated with AEAB degrees, a significant challenge universities and AEAB graduates face is a general lack of recognition of what agricultural economics is and what an agricultural economist does. Using data collected from U.S. 1862 and 1890 land grant universities, we stress the importance of designing effective AEAB curricula based on enrollment trends, …

An Integrated Approach To Analyzing Risk In Bioeconomic Models, Biswo N. Poudel, Krishna P. Paudel Aug 2018

An Integrated Approach To Analyzing Risk In Bioeconomic Models, Biswo N. Poudel, Krishna P. Paudel

Faculty Publications

Copyright © 2018 Wiley Periodicals, Inc. Abstract: We provide a new integrated approach to analyzing risk in a setting where both exogenous and endogenous risks are present. We explicitly model these risks to understand their implications to the precautionary principle. We find that, among other things, the increase of exogenous risk in the presence of endogenous risk has a different impact on precaution than the increase in exogenous risk in the presence of only exogenous risk. While the latter is known to decrease precaution, the former unambiguously increases the precaution in the presence of stock effect. Recommendations for Resource Managers: …

Multiphoton Discrete Fractional Fourier Dynamics In Waveguide Beam Splitters, Konrad Tschernig, Roberto J. De León-Montiel, Omar S. Magaña-Loaiza, Alexander Szameit, Kurt Busch, Armando Perez-Leija Aug 2018

Multiphoton Discrete Fractional Fourier Dynamics In Waveguide Beam Splitters, Konrad Tschernig, Roberto J. De León-Montiel, Omar S. Magaña-Loaiza, Alexander Szameit, Kurt Busch, Armando Perez-Leija

Faculty Publications

We demonstrate that when a waveguide beam splitter (BS) is excited by N indistinguishable photons, the arising multiphoton states evolve in a way as if they were coupled to each other with coupling strengths that are identical to the ones exhibited by a discrete fractional Fourier system. Based on the properties of the fractional Fourier transform, we then derive a multiphoton suppression law for 50/50 BSs, thereby generalizing the Hong–Ou–Mandel effect. Furthermore, we examine the possibility of performing simultaneous multiphoton quantum random walks by using a single waveguide BS in combination with photon-number-resolving detectors. We anticipate that the multiphoton lattice-like …

Faculty Publications

This paper reports measurements of final-state proton multiplicity, muon and proton kinematics, and their correlations in charged-current pionless neutrino interactions, measured by the T2K ND280 near detector in its plastic scintillator (C8H8) target. The data were taken between years 2010 and 2013, corresponding to approximately 6×1020 protons on target. Thanks to their exploration of the proton kinematics and of imbalances between the proton and muon kinematics, the results offer a novel probe of the nuclear-medium effects most pertinent to the (sub-)GeV neutrino-nucleus interactions that are used in accelerator-based long-baseline neutrino oscillation measurements. These results are compared to many neutrino-nucleus interaction …

The Stochastic Order Of Probability Measures On Ordered Metric Spaces, Fumio Hiai, Jimmie Lawson, Yongdo Lim Aug 2018

The Stochastic Order Of Probability Measures On Ordered Metric Spaces, Fumio Hiai, Jimmie Lawson, Yongdo Lim

Faculty Publications

The general notion of a stochastic ordering is that one probability distribution is smaller than a second one if the second attaches more probability to higher values than the first. Motivated by recent work on barycentric maps on spaces of probability measures on ordered Banach spaces, we introduce and study a stochastic order on the space of probability measures P(X), where X is a metric space equipped with a closed partial order, and derive several useful equivalent versions of the definition. We establish the antisymmetry and closedness of the stochastic order (and hence that it is a closed partial order) …

Total Hemispherical Apparent Radiative Properties Of The Infinite V-Groove With Diffuse Reflection, Rydge B. Mulford, Nathan S. Collins, Michael S. Farnsworth, Matthew R. Jones, Brian D. Iverson Aug 2018

Total Hemispherical Apparent Radiative Properties Of The Infinite V-Groove With Diffuse Reflection, Rydge B. Mulford, Nathan S. Collins, Michael S. Farnsworth, Matthew R. Jones, Brian D. Iverson

Faculty Publications

DYNAMIC control of radiative surface properties enables optimization of thermal management systems for spacecraft, radiative cooling systems, and other applications [1–3]. Various methods of altering the absorption or emission from a surface have been investigated [4–6]. Use of origami-inspired tessellated surfaces to control apparent radiative surface properties is a promising technology [7–9]. Realizing the full potential of tessellated surfaces to dynamically control apparent radiative surface properties requires convenient methods of calculating apparent properties as a function of tessellation geometry and intrinsic radiative surface properties. This Note focuses on the use of geometry to affect total, hemispherical properties of V grooves …

Influence Of Physicians’ Beliefs On Propensity To Include Religion/Spirituality In Patient Interactions, Aaron B. Franzen Aug 2018

Influence Of Physicians’ Beliefs On Propensity To Include Religion/Spirituality In Patient Interactions, Aaron B. Franzen

Faculty Publications

This study examines physicians’ beliefs, their perceptions of whether religion impacts health outcomes, and their propensity to discuss religion/spirituality with patients. It is not uncommon for patients to want religious/spiritual conversations, but the occurrence is infrequent. This study adds to knowledge regarding which physicians include these topics. Using a nationally representative sample of physicians and a mediated bi-factor structural equation model, the author finds that “religious and spiritual” physicians connect religion and patient health more than other religious/spiritual orientations. As a result, “religious and spiritual” physicians include religion/spirituality most often (indirect path). After this variation is accounted for, “spiritual but …

Analytical Model To Detect Fault Permeability Alteration Induced By Fault Reactivation In Compartmentalized Reservoirs, Oscar M. Molina, Mehdi Zeidouni Aug 2018

Analytical Model To Detect Fault Permeability Alteration Induced By Fault Reactivation In Compartmentalized Reservoirs, Oscar M. Molina, Mehdi Zeidouni

Faculty Publications

Underground fluid injection induces changes in in situ stress condition of the target formation and local faults that can potentially lead to fault reactivation, which may result in the leakage of injected and/or native fluids into neighboring formations. In this paper, we introduce an analytical method to detect fault reactivation caused by fluid injection into deep faulted aquifers considering across-fault leakage. The fundamental assumption made in our model is that fault permeability will be altered upon fault slip. Therefore, we model fault reactivation as a sudden change in fault permeability at the onset of fault slip. The fault is modeled …

Externalizing The Core Principles Of The Departmental Action Team (Dat) Model, Joel Corbo, Gina Quan, Karen Falkenberg, Christopher Geanious, Courtney Ngai, Mary Pilgrim, Daniel Reinholz, Sarah Wise

Faculty Publications

Departmental Action Teams (DATs) are departmentally-based working groups of faculty, students, and staffaimed at achieving sustained departmental change related to undergraduate education. DATs have been conceptualized and are facilitated by members of our project team based on a set of Core Principles. These principles serve both as guides in the design of DATs and targets for the kinds of culture we aspire to create through our facilitation. In this paper, we describe our Core Principles, including theoretical underpinnings and a brief implementation example for each. We argue that articulating principles is a critical component of externalizing acomplex change effort and …

Research On University Faculty Member's Reasoning About How Departments Change, Gina Quan, Joel Corbo, Courtney Ngai, Daniel Reinholz, Mary Pilgrim

Faculty Publications

Research on institutional change says that effective change agents are able to flexibly reason with multiple models for change, depending on their local context and their goals. However, little is known about what it looks like for individuals to draw on and reason with different change models in-the-moment. Within interviews, we invited STEM faculty to discuss specific changes in their department and the process of change in general. This work is part of an ongoing study to understand how to support departmental change through Departmental Action Teams (DATs).  Our preliminary analyses suggest that faculty's ideas about change are highly varied …

Pondering Zeros: Uncovering Hidden Inequities Within A Decade Of Grades, Cassandra Paul Aug 2018

Pondering Zeros: Uncovering Hidden Inequities Within A Decade Of Grades, Cassandra Paul

Faculty Publications

When assessing student work, graders will often find that some students will leave one or more problems blank on assessments. Since there is no work shown, the grader has no means to evaluate the student's understanding of a particular problem, and thus awards zero points. This practice punishes the student behavior of leaving a problem blank, but this zero is not necessarily an accurate assessment of student understanding of a particular topic. While some might argue that this grading practice is "fair" in that students know that they can't receive points for answers they don't submit, we share evidence that …

Evaluation Criteria For Selecting Nosql Databases In A Single Box Environment, Ryan D. Engle, Brent T. Langhals, Michael R. Grimaila, Douglas D. Hodson Aug 2018

Evaluation Criteria For Selecting Nosql Databases In A Single Box Environment, Ryan D. Engle, Brent T. Langhals, Michael R. Grimaila, Douglas D. Hodson

Faculty Publications

In recent years, NoSQL database systems have become increasingly popular, especially for big data, commercial applications. These systems were designed to overcome the scaling and flexibility limitations plaguing traditional relational database management systems (RDBMSs). Given NoSQL database systems have been typically implemented in large-scale distributed environments serving large numbers of simultaneous users across potentially thousands of geographically separated devices, little consideration has been given to evaluating their value within single-box environments. It is postulated some of the inherent traits of each NoSQL database type may be useful, perhaps even preferable, regardless of scale. Thus, this paper proposes criteria conceived to …

Nickel Exposure Reduces Enterobactin Production In Escherichia Coli, Clorissa L. Washington-Hughes, Geoffrey T. Ford, Alsten D. Jones, Kimberly Mcrae, Franklin Wayne Outten Jul 2018

Nickel Exposure Reduces Enterobactin Production In Escherichia Coli, Clorissa L. Washington-Hughes, Geoffrey T. Ford, Alsten D. Jones, Kimberly Mcrae, Franklin Wayne Outten

Faculty Publications

Escherichia coli is a well- studied bacterium that can be found in many niches, such as industrial wastewater, where the concentration of nickel can rise to low- millimolar levels. Recent studies show that nickel exposure can repress pyochelin or induce pyo-verdine siderophore production in Pseudomonas aueroginosa. Understanding the mo-lecular cross- talk between siderophore production, metal homeostasis, and metal toxicity in microorganisms is critical for designing bioremediation strategies for metal- contaminated sites. Here, we show that high- nickel exposure prolongs lag phase duration as a result of low- intracellular iron levels in E. coli. Although E. coli cells respond to low- …

Lightweight Call-Graph Construction For Multilingual Software Analysis, Anne-Marie Bogar, Damian Lyons, David Baird Jul 2018

Lightweight Call-Graph Construction For Multilingual Software Analysis, Anne-Marie Bogar, Damian Lyons, David Baird

Faculty Publications

Analysis of multilingual codebases is a topic of increasing importance. In prior work, we have proposed the MLSA (MultiLingual Software Analysis) architecture, an approach to the lightweight analysis of multilingual codebases, and have shown how it can be used to address the challenge of constructing a single call graph from multilingual software with mutual calls. This paper addresses the challenge of constructing monolingual call graphs in a lightweight manner (consistent with the objective of MLSA) which nonetheless yields sufficient information for resolving language interoperability calls. A novel approach is proposed which leverages information from …

The strong chromatic index of a graph G, denoted χ′s(G), is the least number of colors needed to edge-color G so that edges at distance at most two receive distinct colors. The strong list chromatic index, denoted χ′s,ℓ(G), is the least integer k such that if arbitrary lists of size k are assigned to each edge then G can be edge-colored from those lists where edges at distance at most two receive distinct colors.We use the discharging method, the Combinatorial Nullstellensatz, and computation to show that if G is a subcubic planar graph with girth(G)≥41 then χ′s,ℓ(G)≤5, answering a question …
