Tracking And Parameter Identification For Model Reference Adaptive Control, Michael Malisoff

Faculty Publications

We provide barrier Lyapunov functions for model reference adaptive control algorithms, allowing us to prove robustness in the input-to-state stability framework and to compute rates of exponential convergence of the tracking and parameter identification errors to zero. Our results ensure identification of all entries of the unknown weight and control effectiveness matrices. We provide easily checked sufficient conditions for our relaxed persistency of excitation conditions to hold. Our illustrative numerical example demonstrates the performance of the control methods.

Remote Sensing Derived Indices For Tracking Urban Land Surface Change In Case Of Earthquake Recovery, Sahar Derakhshan, Susan Lynn Cutter, Cuizhen Wang

Faculty Publications

The study of post-disaster recovery requires an understanding of the reconstruction process and growth trend of the impacted regions. In case of earthquakes, while remote sensing has been applied for response and damage assessment, its application has not been investigated thoroughly for monitoring the recovery dynamics in spatially and temporally explicit dimensions. The need and necessity for tracking the change in the built-environment through time is essential for post-disaster recovery modeling, and remote sensing is particularly useful for obtaining this information when other sources of data are scarce or unavailable. Additionally, the longitudinal study of repeated observations over time in …

Overlaps Of Deformed And Non-Deformed Harmonic Oscillator Basis States, David Kekejian, Jerry P. Draayer, Tomáš Dytrych, Kristina D. Launey

Faculty Publications

A systematic approach for expanding non-deformed harmonic oscillator basis states in terms of deformed ones, and vice versa, is presented. The objective is to provide analytical results for calculating these overlaps (transformation brackets) between deformed and non-deformed basis states in spherical, cylindrical, and Cartesian coordinates. These overlaps can be used for reducing the complexity of different research problems that employ three-dimensional harmonic oscillator basis states, for example as used in coherent state theory and the nuclear shell-model, especially within the context of ab initio symmetry-adapted no-core shell model.

Landscape Performance Of Buck Roses Under Minimal-Input Conditions In North-Central Texas, Derald A. Harp, Gaye Hammond, David C. Zlesak, Greg Church, Mark Chamblee, Steve George

Faculty Publications

Griffith Buck (Iowa State University) bred roses (Rosa sp.) to survive long, cold winters and hot, humid summers yet still retain their foliage without fungicides. Unfortunately, there is little known about the performance of Buck roses in the southern United States. Thirty-eight Buck rose cultivars were evaluated for flowering, disease resistance, drought tolerance, and overall landscape performance in alkaline soils with no fertilizer, no pesticides, and only limited irrigation. Flowering occurred on a bimodal basis, with the highest per plant mean bloom number (16.3 blooms) and bloom coverage (9.7%) in April, and a second flowering in the fall, with …

Efficiently Computable Bounds For Magic State Distillation, Xin Wang, Mark M. Wilde, Yuan Su

Faculty Publications

Magic-state distillation (or nonstabilizer state manipulation) is a crucial component in the leading approaches to realizing scalable, fault-tolerant, and universal quantum computation. Related to nonstabilizer state manipulation is the resource theory of nonstabilizer states, for which one of the goals is to characterize and quantify nonstabilizerness of a quantum state. In this Letter, we introduce the family of thauma measures to quantify the amount of nonstabilizerness in a quantum state, and we exploit this family of measures to address several open questions in the resource theory of nonstabilizer states. As a first application, we establish the hypothesis testing thauma as …

The Impact Of "Strike Hard" On Repeat And Near-Repeat Residential Burglary In Beijing, Peng Chen, Justin Kurland

Faculty Publications

“Strike Hard” is an enhanced law-enforcement strategy in China that aims to suppress crime, but measurement of the crime-reducing effect and potential changes in the spatiotemporal concentration of crime associated with “Strike Hard” remain unknown. This paper seeks to examine the impact, if any, of “Strike Hard” on the spatiotemporal clustering of burglary incidents. Two and half years of residential burglary incidents from Chaoyang, Beijing are used to examine repeat and near-repeat burglary incidents before, during, and after the “Strike Hard” intervention and a new technique that enables the comparison of repeat and near repeat patterns across different temporal periods …

The Seasonal Evolution Of Albedo Across Glaciers And The Surrounding Landscape Of Taylor Valley, Antarctica, Anna Bergstrom, Michael N. Gooseff, Madeline Myers, Peter T. Doran, Julian M. Cross

Faculty Publications

© Author(s) 2020. The McMurdo Dry Valleys (MDVs) of Antarctica are a polar desert ecosystem consisting of alpine glaciers, ice-covered lakes, streams, and expanses of vegetation-free rocky soil. Because average summer temperatures are close to 0 °C, the MDV ecosystem in general, and glacier melt dynamics in particular, are both closely linked to the energy balance. A slight increase in incoming radiation or change in albedo can have large effects on the timing and volume of meltwater. However, the seasonal evolution or spatial variability of albedo in the valleys has yet to fully characterized. In this study, we aim to …

Magslam: Aerial Simultaneous Localization And Mapping Using Earth's Magnetic Anomaly Field, Taylor N. Lee, Aaron J. Canciani

Faculty Publications

Instances of spoofing and jamming of global navigation satellite systems (GNSSs) have emphasized the need for alternative navigation methods. Aerial navigation by magnetic map matching has been demonstrated as a viable GNSS‐alternative navigation technique. Flight test demonstrations have achieved accuracies of tens of meters over hour‐long flights, but these flights required accurate magnetic maps which are not always available. Magnetic map availability and resolution vary widely around the globe. Removing the dependency on prior survey maps extends the benefits of aerial magnetic navigation methods to small unmanned aerial systems (sUAS) at lower altitudes where magnetic maps are especially undersampled or …

Hyaluronic Acid-Cellulose Composites As Patches For Minimizing Bacterial Infections, Kelsey M. Lopez, Sudhir Ravula, Rocío L. Pérez, Caitlan E. Ayala, Jack N. Losso, Marlene E. Janes, Isiah M. Warner

Faculty Publications

Copyright © 2020 American Chemical Society. A facile method was used to synthesize biocomposites containing differing ratios of hyaluronic acid (HA) and cellulose (CEL). Based on the properties of the individual polymers, the resultant composite materials may have potentially great wound care properties. In the method outlined here, 1-butyl-3-methylimidazolium chloride ([Bmim][Cl]), a simple ionic liquid, was used as the sole solvent without chemical modifiers to dissolve the biopolymers at ratios of 1:1 and 2:1 HA to CEL. This method was completely recyclable since the ionic liquid, [Bmim][Cl], can be recovered. Results from spectroscopic measurements [Fourier transform infrared (FT-IR) and X-ray …

Climate And Plant Community Diversity In Space And Time, Susan Harrison, Marko J. Spasojevic, Daijiang Li

Faculty Publications

© 2020 National Academy of Sciences. All rights reserved. Climate strongly shapes plant diversity over large spatial scales, with relatively warm and wet (benign, productive) regions supporting greater numbers of species. Unresolved aspects of this relationship include what causes it, whether it permeates to community diversity at smaller spatial scales, whether it is accompanied by patterns in functional and phylogenetic diversity as some hypotheses predict, and whether it is paralleled by climate-driven changes in diversity over time. Here, studies of Californian plants are reviewed and new analyses are conducted to synthesize climate-diversity relationships in space and time. Across spatial scales …

Fully Automated Bone Age Assessment On Large-Scale Hand X-Ray Dataset, Xiaoyang Pan, Yizhe Zhao, Hao Chen, De Wei, Chen Zhao, Zhi Wei

Faculty Publications

Bone age assessment (BAA) is an essential topic in the clinical practice of evaluating the biological maturity of children. Because the manual method is time-consuming and prone to observer variability, it is attractive to develop computer-aided and automated methods for BAA. In this paper, we present a fully automatic BAA method. To eliminate noise in a raw X-ray image, we start with using U-Net to precisely segment hand mask image from a raw X-ray image. Even though U-Net can perform the segmentation with high precision, it needs a bigger annotated dataset. To alleviate the annotation burden, we propose to use …

Toward A Systematic Theology Of The Sanctuary: Part 2, John C. Peckham

Faculty Publications

This article is part two of an essay that offers some preliminary thoughts regarding the relationship of the sanctuary and systematic theology, focusing on just a few aspects which expose the relationship between the two. The first article considered the nature of theological systems, issues related to an Adventist system of theology, and the relationship between fundamental theology and the sanctuary in particular, with attention to some broad, competing views of the sanctuary that are integrally related to the way one conceives of broader theological principles. The first article set the stage for this second article, which concludes the essay …

Parkinson's Disease In Louisiana, 1999-2012: Based On Hospital Primary Discharge Diagnoses, Incidence, And Risk In Relation To Local Agricultural Crops, Pesticides, And Aquifer Recharge, Martin E. Hugh-Jones, R. Hampton Peele, Vincent L. Wilson

Faculty Publications

The two major causes of Parkinson's disease (PD) are genetic susceptibility and exposure to agricultural pesticides. Access to 23,224 individuals' hospital primary discharge diagnoses of PD allowed the mapping of cases against known crop distributions and pesticides. Our main objective was to map PD risks (cases per 10,000 people) against crops and their pesticides. The ZIP Code address locations, and the 2000 and 2010 census data, were used to map the risks of PD throughout Louisiana and in relation to United States Department of Agriculture (USDA)-recorded crops. The introduction of glyphosate-resistant crops appears to have initiated the PD disappearance from …

Comparing Self-Reported Medication Adherence Measures With Hair Antiretroviral Concentration Among People Living With Hiv In Guangxi, China, Quan Zhang, Xiaoming Li Ph.D., Shan Qiao Ph.D., Zhiyong Shen, Yuejiao Zhou

Faculty Publications

Background: Antiretroviral adherence is essential to HIV treatment efcacy. Various self-reported measures are commonly used for assessing antiretroviral adherence. Limited data are available regarding the validity of those selfreported measures in comparison with long-term objective biomarkers of adherence measures such as hair measures.

Methods: Self-reported adherence (frequency, percentage, and visual analog scale [VAS]) and hair tenofovir concentration were evaluated at a single time point from 268 people living with HIV in China. The responses to each of three self-reported measures were converted into percentage and then dichotomized as “optimal” (100%) vs. “suboptimal” (less than 100%) adherence. Two composite adherence scores …

Mirror, Mirror On The Wall: The Effect Of Listening To Body Positive Music On Implicit And Explicit Body Esteem, Sarah M. Coyne, Emilie J. Davis, Wayne Warburton, Laura Stockdale, Imogen Abba, Dean M. Busby

Faculty Publications

The current article used 3 studies to examine the impact of listening to body positive music on both explicit and implicit measures of body esteem in women. Study 1 found that women who viewed a mainstream popular body positive music video reported higher levels of body esteem than those who viewed a popular body objectifying music video. In Studies 2 and 3, we wrote and recorded our own songs to keep the musical features apart from the lyrics constant (e.g., rhythm, melody, and singer identity). Study 2 also found that women showed higher levels of implicit (but not explicit) body …

Minimizing Total Energy Cost And Tardiness Penalty For A Scheduling-Layout Problem In A Flexible Job Shop System: A Comparison Of Four Metaheuristic Algorithms, Ahmad Ebrahimi, Hyun Woo Jeon, Seokgi Lee, Chao Wang

Faculty Publications

Job scheduling and machine layout are interrelated in improving energy consumption (EC) and productivity measures such as tardiness and represent two important decisions that must be made by manufacturers. This interdependency can be explained by transportation time, which connects scheduling and layout. Scheduling and layout, however, have not been thoroughly studied in conjunction using an integrated model in the context of sustainable manufacturing. Hence, we propose an energy-aware optimization model in which scheduling is integrated with layout in a single-level framework. More specifically, a single objective function is defined to minimize the facility energy cost and the job tardiness penalty, …

Modeling And Data Infrastructure For Human-Centric Design And Operation Of Sustainable, Healthy Buildings Through A Case Study, Yong X. Tao, Yimin Zhu, Ulrike Passe

Faculty Publications

This paper focuses on data infrastructure that is central to the modeling of design and operation of sustainable and healthy buildings. While reducing energy consumption by making buildings more energy efficient has been touted as an easily obtainable approach to promoting carbon-neutral energy societies, the sustainable buildings’ benefits and impacts on human wellbeing have not been clearly quantified to the extent that they may directly influence the decision of adopting sustainable building designs. The authors argue that focusing on the wellbeing of people occupying the buildings will lead to significant changes in the decision-making process of the design and operation …

Mincing No Words: When The Court's Opinion Criticizes An Advocate's Writing, Douglas E. Abrams

Faculty Publications

In recent years, court opinions have chastised counsel’s briefs or other written submissions for such structural deficiencies as improper citations; missing exhibit labels; incomplete tables of citations; mis-numbered counts; failure to cite to the record; and skirting of court rules that regulate font size, maximum page limits, mandated margins, and the like. Beyond structure, opinions have also chastised counsel for written submissions that are “riddled with misspellings, typographical errors, punctuation errors, and grammar and usage errors” and for those marked by careless cutting-and-pasting from forms or other prior work product, or by careless reliance on spell-check.

Low-Phosphate Chromatin Dynamics Predict A Cell Wall Remodeling Network In Rice Shoots, Maryam Foroozani, Sara Zahraeifard, Dong Ha Oh, Guannan Wang, Maheshi Dassanayake, Aaron P. Smith

Faculty Publications

© 2020 American Society of Plant Biologists. All Rights Reserved. Phosphorus (P) is an essential plant macronutrient vital to fundamental metabolic processes. Plant-available P is low in most soils, making it a frequent limiter of growth. Declining P reserves for fertilizer production exacerbates this agricultural challenge. Plants modulate complex responses to fluctuating P levels via global transcriptional regulatory networks. Although chromatin structure plays a substantial role in controlling gene expression, the chromatin dynamics involved in regulating P homeostasis have not been determined. Here we define distinct chromatin states across the rice (Oryza sativa) genome by integrating multiple chromatin marks, including …

Heat Shock Protein 70 Levels And Post-Harvest Survival Of Eastern Oysters Following Sublethal Heat Shock In The Laboratory Or Conditioning In The Field, Sandra M. Casas, Jerome F. La Peyre

Faculty Publications

© 2020, Cell Stress Society International. A major problem of storing and shipping eastern oysters (Crassostrea virginica) from the Northern Gulf of Mexico in summer and early fall is their elevated mortality. A study was therefore conducted to determine whether heat shocking the oysters or conditioning them to aerial exposure prior to harvest could reduce their mortality during cold storage. Increasing the levels of stress proteins in bivalves has been shown to reduce their mortality when exposed to additional stressors. In this study, the levels of heat shock protein 70 (HSP70) proteins and cumulative mortality during cold storage, out of …
