Interest in high-spin organic materials is driven by opportunities to enable far-reaching fundamental science and develop technologies that integrate light element spin, magnetic, and quantum functionalities. Although extensively studied, the intrinsic instability of these materials complicates synthesis and precludes an understanding of how fundamental properties associated with the nature of the chemical bond and electron pairing in organic materials systems manifest in practical applications. Here, we demonstrate a conjugated polymer semiconductor, based on alternating cyclopentadithiophene and thiadiazoloquinoxaline units, that is a ground-state triplet in its neutral form. Electron paramagnetic resonance and magnetic susceptibility measurements are consistent with a high-to-low spin …

Review Of Quantitative Methods For Supply Chain Resilience Analysis, Seyedmohsen Hosseini, Dmitry Ivanov, Alexandre Dolgui

Faculty Publications

Supply chain resilience (SCR) manifests when the network is capable to withstand, adapt, and recover from disruptions to meet customer demand and ensure performance. This paper conceptualizes and comprehensively presents a systematic review of the recent literature on quantitative modeling the SCR while distinctively pertaining it to the original concept of resilience capacity. Decision-makers and researchers can benefit from our survey since it introduces a structured analysis and recommendations as to which quantitative methods can be used at different levels of capacity resilience. Finally, the gaps and limitations of existing SCR literature are identified and future research opportunities are suggested.

Difference Of Opinion: Spousal Influence On Cancer Risk-Reducing Behavior, Wendy C. Birmingham, Maija Reblin, Wendy Kohlmann, Tyler Graff

Faculty Publications

Marriage is consistently associated with better health outcomes. Spouses' attempts to influence partners' lifestyle and general health behaviors may contribute to this effect, although partners may not be aware of this influence. Spousal worry of a cancer diagnosis for an at-risk partner may factor into attempts to influence. An examination of spousal worry and influence on lifestyle choices, general health behaviors, and cancer screening adherence for partners at higher risk of colorectal cancer may shed light on spousal influence and partners' perceptions of influence. Methods: A mixed-method design assessed cancer worry and spousal influence for risk-reducing behavior in first-degree relatives …

Celebration Of Diversity, Katelyn Campbell, S. Joseph Kidder

Faculty Publications

Diversity is worth celebrating. It can be incredibly helpful in bringing us together in dialogue, love, and mission. By engaging with our differences, we can not only reach more people effectively for the kingdom of God but also be more united as a church body. When we choose to listen to, dialogue with, and learn from one another, we allow ourselves to be humbled. We cannot be united in our diversity and remain proud of heart. It is a spirit of humility that allows us to truly connect not only with those with whom we agree but also with those …

A Comparison Of Hominin Teeth From Lincoln Cave, Sterkfontein L/63, And The Dinaledi Chamber, South Africa, Juliet K. Brophy, Joel Irish, Steve E. Churchill, Darryl J. De Ruiter, John Hawks, Lee R. Berger

Faculty Publications

Prior to the recovery of Homo naledi from the Dinaledi Chamber of the Rising Star Cave system, the Middle Pleistocene fossil record in Africa was particularly sparse. With the large sample size now available from Dinaledi, the opportunity exists to reassess taxonomically ambiguous teeth unearthed at the nearby site of Sterkfontein. Teeth recovered from Lincoln Cave South and area L/63 at Sterkfontein have been considered ‘most probably Homo ergaster’ and ‘perhaps Archaic Homo sapiens’, respectively. Given the similarities shared between Lincoln Cave, area L/63, and the Dinaledi Chamber with regard to climatic/geologic depositional context and age, two teeth from the …

The Power Of Prosecutors, Jeffrey Bellin

Faculty Publications

One of the predominant themes in the criminal justice literature is that prosecutors dominate the justice system. Over seventy-five years ago, Attorney General Robert Jackson famously proclaimed that the “prosecutor has more control over life, liberty, and reputation than any other person in America.” In one of the most cited law review articles of all time, Bill Stuntz added that prosecutors—not legislators, judges, or police—“are the criminal justice system’s real lawmakers.” And an unchallenged modern consensus holds that prosecutors “rule the criminal justice system.”

This Article applies a critical lens to longstanding claims of prosecutorial preeminence. It reveals a curious …

An Organizational Account Of State Standing, Katherine Mims Crocker

Faculty Publications

Again and again in regard to recent high-profile disputes, the legal community has tied itself in knots over questions about when state plaintiffs should have standing to sue in federal court, especially in cases where they seek to sue federal-government defendants. Lawsuits challenging everything from the Bush administration’s environmental policies to the Obama administration’s immigration actions to the Trump administration’s travel bans have become mired in tricky and technical questions about whether state plaintiffs belonged in federal court.

Should state standing cause so much controversy and confusion? This Essay argues that state plaintiffs are far more like at least one …

Finding The Symmetry Group Of An Lp With Equality Constraints And Its Application To Classifying Orthogonal Arrays, Andrew J. Geyer, Dursun A. Bulutoglu, Kenneth J. Ryan

Faculty Publications

Excerpt: For a given linear program (LP) a permutation of its variables that sends feasible points to feasible points and preserves the objective function value of each of its feasible points is a symmetry of the LP. The set of all symmetries of an LP, denoted by G^LP, is the symmetry group of the LP. Margot (2010) described a method for computing a subgroup of the symmetry group G^LP of an LP. This method computes G^LP when the LP has only non-redundant inequalities and its feasible set satisfies no equality constraints.

From Trash To Treasure: The Impact Of Consumer Perception Of Bio-Waste Products In Closed-Loop Supply Chains, Ivan Russo, Ilenia Confente, Daniele Scarpi, Benjamin T. Hazen

Faculty Publications

Increasing efforts are made to convert waste into new materials for replacing “traditional” ones. In particular urban bio-waste represents a primary source of concern for both government and society. A new type of polyhydroxyalkanoates (PHA) have been very recently developed to convert food waste into a biodegradable multifunctional raw material to help solving the plastic waste problem. However, little is known about consumers' reactions to products made from PHA. Hence this study aims at understanding consumers' intentions to purchase, pay for, and switch to those bio-based products. Both multivariate analyses of variance and mediation analyses are run, addressing product involvement, …

How Do Neighbourhood Definitions Influence The Associations Between Built Environment And Physical Activity?, Suzanne Mavoa, Nasser Bagheri, Mohammad Javad Koohsari, Andrew T. Kaczynski, Karen E. Lamb, Koichiro Oka, David O'Sullivan, Karen Witten

Faculty Publications

Researchers investigating relationships between the neighbourhood environment and health first need to decide on the spatial extent of the neighbourhood they are interested in. This decision is an important and ongoing methodological challenge since different methods of defining and delineating neighbourhood boundaries can produce different results. This paper explores this issue in the context of a New Zealand-based study of the relationship between the built environment and multiple measures of physical activity. Geographic information systems were used to measure three built environment attributes—dwelling density, street connectivity, and neighbourhood destination accessibility—using seven different neighbourhood definitions (three administrative unit boundaries, and 500, …

First-Principles Study Of Feo2HX Solid And Melt System At High Pressures: Implications For Ultralow-Velocity Zones, Jie Deng, Bijaya B. Karki, Dipta B. Ghosh, Kanani K.M. Lee

Faculty Publications

Pyrite-type FeO H (P phase) has recently been suggested as a possible alternative to explain ultralow-velocity zones due to its low seismic velocity and high density. Here we report the results on the congruent melting temperature and melt properties of P phase at high pressures from first-principles molecular dynamics simulations. The results show that P phase would likely be melted near the core–mantle boundary. Liquid FeO H has smaller density and smaller bulk sound velocity compared to the isochemical P phase. As such, relatively small amounts of liquid FeO H could account for the observed seismic anomaly of ultralow-velocity zones. …

A Two Decadal (1993-2012) Numerical Assessment Of Sediment Dynamics In The Northern Gulf Of Mexico, Zhengchen Zang, Z. George Xue, Kehui Xu, Samuel J. Bentley, Qin Chen, Eurico J. D'Sa, Qian Ge

Faculty Publications

© 2019 by the authors. We adapted the coupled ocean-sediment transport model to the northern Gulf of Mexico to examine sediment dynamics on seasonal-to-decadal time scales as well as its response to decreased fluvial inputs from the Mississippi-Atchafalaya River. Sediment transport on the shelf exhibited contrasting conditions in a year, with strong westward transport in spring, fall, and winter, and relatively weak eastward transport in summer. Sedimentation rate varied from almost zero on the open shelf to more than 10 cm/year near river mouths. A phase shift in river discharge was detected in 1999 and was associated with the El …

Comparison Of Anthracnose Resistance With The Presence Of Two Scar Markers Associated With The Rca2 Gene In Strawberry, Melinda A. Miller-Butler, Barbara J. Smith, Brian R. Kreiser, Eugene K. Blythe

Faculty Publications

Strawberry anthracnose diseases are caused primarily by three Colletotrichum species: C. acutatum J.H. Simmonds, C. fragariae A.N. Brooks, and C. gloeosporioides (Penz.) Penz. & Sacc. Molecular markers are being used in breeding programs to identify alleles linked to disease resistance and other positive agronomic traits. In our study, strawberry cultivars and breeding germplasm with known anthracnose susceptibility or resistance to the three anthracnose-causing Colletotrichum species were screened for two sequence characterized amplified region (SCAR) markers linked to the Rca2 gene. The Rca2 resistant allele SCAR markers were associated with varying degrees of significance for a strawberry plant’s anthracnose resistance to …

Data-Driven Estimation Of Significant Kinetic Parameters Applied To The Synthesis Of Polyolefins, Santiago D. Salas, Amanda L.T. Brandão, João B.P. Soares, José A. Romagnoli

Faculty Publications

A data-driven strategy for the online estimation of important kinetic parameters was assessed for the copolymerization of ethylene with 1,9-decadiene using a metallocene catalyst at different diene concentrations and reaction temperatures. An initial global sensitivity analysis selected the significant kinetic parameters of the system. The retrospective cost model refinement (RCMR) algorithm was adapted and implemented to estimate the significant kinetic parameters of the model in real time. After verifying stability and robustness, experimental data validated the algorithm performance. Results demonstrate the estimated kinetic parameters converge close to theoretical values without requiring prior knowledge of the polymerization model and the original …

Balanced Parallel Exploration Of Orthogonal Regions, Wyatt Clements, Costas Busch, Limeng Pu, Daniel Smith, Hsiao Chun Wu

Faculty Publications

We consider the use of multiple mobile agents to explore an unknown area. The area is orthogonal, such that all perimeter lines run both vertically and horizontally. The area may consist of unknown rectangular holes which are non-traversable internally. For the sake of analysis, we assume that the area is discretized into N points allowing the agents to move from one point to an adjacent one. Mobile agents communicate through face-to-face communication when in adjacent points. The objective of exploration is to develop an online algorithm that will explore the entire area while reducing the total work of all k …

Steadfast Standards Or Fluctuating Fancies? Stability And Change In People’S Mate Criteria Over 27 Months, Carrie A. Bredow, Nicole Hames

Faculty Publications

Although research on mate preferences has been built on the assumption that the criteria people report at one point in time should predict their future partnering behavior, little is known about the temporal stability of people’s standards. Using survey data collected at four time points from 285 originally unmarried individuals, this study examined the rank-order, meanlevel, individual-level and ipsative stability of people’s mate criteria over 27 months. Overall, reported standards exhibited moderate to high baseline stability, with rank-order and ipsative estimates comparable to those reported for personality traits. At the same time, mean- and individual-level analyses revealed small, but significant, …

Quasi-Sovereign Standing, F. Andrew Hessick

Faculty Publications

This essay proceeds in five Parts. Part I describes the three strands of state standing. It focuses particularly on parens patriae standing to assert quasi-sovereign interests. Part II criticizes the parens patriae framework. It argues that states hold quasi-sovereign interests and accordingly should have direct standing to assert them. Part III argues that states should be able to assert these interests against the United States because of the unique role that states play in our federal system. Part IV argues that recognizing state standing to bring these suits is consistent with the separation of powers theories underlying standing doctrine. Part …

America's Founding Editors: Writing The Declaration Of Independence, Douglas E. Abrams

Faculty Publications

On Congress’ behalf, one of its members, 33-year-old Virginia lawyer Thomas Jefferson, drafted the Declaration of Independence. For the next half century, Jefferson’s fierce pride of authorship, unrestrained by humility, kept him from crediting Congress for skilled editing that helped make him a national icon by sharpening his powerful, but less than polished, draft. The irony of lawyer Jefferson’s enduring bitterness and ingratitude can stimulate today’s lawyers to sharpen their own drafts by respecting cooperative editors as valuable allies, not as troublesome adversaries.

Incentivizing Cyber Security Investment In The Power Sector Using An Extended Cyber Insurance Framework, Jack P. Rosson, Mason J. Rice, Juan Lopez Jr., R. David Fass

Faculty Publications

Collaboration between the DHS Cybersecurity and Infrastructure Security Agency (CISA) and public-sector partners has revealed that a dearth of cyber-incident data combined with the unpredictability of cyber attacks have contributed to a shortfall in first-party cyber insurance protection in the critical infrastructure community. This research explores the foundations of insurance theory and adopts behavioral manipulation methods to incentivize cyber-security investment. We validate the model by applying power industry performance data from 2013-2015 to assess risk facing the industry. Results show that the model can successfully discriminate between individual power companies as well as geographic regions on the basis of risk …

Numerical Linked-Cluster Expansions For Disordered Lattice Models, M. D. Mulanix, Demetrius Almada, Ehsan Khatami

Faculty Publications

Imperfections in correlated materials can alter their ground state as well as finite-temperature properties in significant ways. Here, we develop a method based on numerical linked-cluster expansions for calculating exact finite-temperature properties of disordered lattice models directly in the thermodynamic limit. We show that a continuous distribution for disordered parameters can be achieved using a set of carefully chosen discrete modes in the distribution, which allows for the averaging of properties over all disorder realizations. We benchmark our results for thermodynamic properties of the square-lattice Ising and quantum Heisenberg models with bond disorder against Monte Carlo simulations and study them …

More Than Frequency? Exploring Predictors Of Word Difficulty For Second Language Learners, Brett James Hashimoto, Jesse Egbert

Faculty Publications

Frequency is often the only variable considered when researchers or teachers develop vocabulary materials for second language (L2) learners. However, researchers have also found that many other variables affect vocabulary acquisition. In this study, we explored the relationship between L2 vocabulary acquisition and a variety of lexical characteristics using vocabulary recognition test data from L2 English learners. Conducting best subsets multiple regression analysis to explore all possible combinations of variables, we produced a best-fitting model of vocabulary difficulty consisting of six variables (R2 = .37). The fact that many variables significantly contributed to the regression model and that a large …

The Effects Of Ambient Temperature And Lighting Intensity On Wheel-Running Behavior In A Diurnal Rodent, The Nile Grass Rat (Arvicanthis Niloticus), Garrett M. Fogo, Alyssa M. Goodwin, Ohanes S. Khacherian, Brandi J. Ledbetter, Andrew J. Gall

Faculty Publications

Environmental conditions, such as the light-dark cycle and temperature, affect the display of circadian rhythmicity and locomotor activity patterns in mammals. Here, we tested the hypothesis that manipulating these environmental conditions would affect wheel-running activity patterns in a diurnal rodent, the Nile grass rat (Arvicanthis niloticus). Grass rats are diurnal in the field, however, a subset switch from a day-active pattern to a night-active pattern of activity after the introduction of a running wheel. The mechanism of this chronotype switch remains largely unknown. In the present study, grass rats were presented with running wheels in 12:12 light-dark conditions. First, subjects …

The Interior Structure Of Immigration Enforcement, Eisha Jain

Faculty Publications

Deportation dominates immigration policy debates, yet it amounts to a fraction of the work the immigration enforcement system does. This Article maps the interior structure of immigration enforcement, and it seeks to show how attention to its structure offers both practical and conceptual payoffs for contemporary enforcement debates. First, deportation should not be conceptualized as synonymous with immigration enforcement; rather, it is merely the tip of a much larger enforcement pyramid. At the pyramid’s base, immigration enforcement operates through a host of initiatives that build immigration screening into common interactions, such as with police and employers. Second, this enforcement structure …

Ergodicity For The 3d Stochastic Navier-Stokes Equations Perturbed By Lévy Noise, Manil T. Mohan, K. Sakthivel, Sivaguru S. Sritharan

Faculty Publications

In this work we construct a Markov family of martingale solutions for 3D stochastic Navier–Stokes equations (SNSE) perturbed by Lévy noise with periodic boundary conditions. Using the Kolmogorov equations of integrodifferential type associated with the SNSE perturbed by Lévy noise, we construct a transition semigroup and establish the existence of a unique invariant measure. We also show that it is ergodic and strongly mixing.

American Democratic Deficit In Assisted Reproductive Technology Innovation, Myrisha S. Lewis

Faculty Publications

In many areas of innovation, the United States is a leader, but this characterization does not apply to the United States' position in assisted reproductive technology innovation and clinical use. This article uses a political science concept, the idea of the "democratic deficit" to examine the lack of American public discourse on innovations in ART. In doing so, the article focuses on America's missing public consultation in health care innovation. This missing discourse is significant, as political and ethical considerations may impact regulatory decisions. Thus, to the extent that these considerations are influencing the decisions of federal agency employees, namely …
