Concurrent Identification And Characterization Of Protein Structure And Continuous Internal Dynamics With Redcraft, Hanin Omar, Aaron Hein, Casey A. Cole, Homayoun Valafar Feb 2022

Concurrent Identification And Characterization Of Protein Structure And Continuous Internal Dynamics With Redcraft, Hanin Omar, Aaron Hein, Casey A. Cole, Homayoun Valafar

Faculty Publications

Internal dynamics of proteins can play a critical role in the biological function of some proteins. Several well documented instances have been reported such as MBP, DHFR, hTS, DGCR8, and NSP1 of the SARS-CoV family of viruses. Despite the importance of internal dynamics of proteins, there currently are very few approaches that allow for meaningful separation of internal dynamics from structural aspects using experimental data. Here we present a computational approach named REDCRAFT that allows for concurrent characterization of protein structure and dynamics. Here, we have subjected DHFR (PDB-ID 1RX2), a 159-residue protein, to a fictitious, mixed mode model of …

Moral Disengagement Mechanisms Predict Cyber Aggression Among Emerging Adults, Taylor R. Nocera, Eric R. Dahlen, Alison Poor, Jacqueline Strowd, Amanda Dortch, Erica C. Van Overloop

Faculty Publications

The Internet has given rise to many new communication tools (e.g., social media, text messaging), which, while beneficial in many respects, have become a means for aggressing against others. As evidence of the adverse correlates of cyber aggression mounts, improved understanding of the mechanisms that facilitate electronic aggression is needed. Moral disengagement (i.e., cognitive processes through which individuals disengage from their moral values) has been shown to predict cyber aggression when assessed as a unitary construct. The present study investigated the eight moral disengagement mechanisms measured by the Moral Disengagement Measure (Detert et al., 2008) and their relationships to four …

A Comparative Review Of Peridynamics And Phase-Field Models For Engineering Fracture Mechanics, Patrick Diehl, Robert Lipton, Thomas Wick, Mayank Tyagi

Faculty Publications

Computational modeling of the initiation and propagation of complex fracture is central to the discipline of engineering fracture mechanics. This review focuses on two promising approaches: phase-field (PF) and peridynamic (PD) models applied to this class of problems. The basic concepts consisting of constitutive models, failure criteria, discretization schemes, and numerical analysis are briefly summarized for both models. Validation against experimental data is essential for all computational methods to demonstrate predictive accuracy. To that end, the Sandia Fracture Challenge and similar experimental data sets where both models could be benchmarked against are showcased. Emphasis is made to converge on common …

Faculty Publications

Bacterial resistance is responsible for a wide variety of health problems, both in children and adults. The persistence of symptoms and infections are mainly treated with beta-lactam antibiotics. The increasing resistance to those antibiotics by bacterial pathogens generated the emergence of extended-spectrum beta-lactamases (ESBLs), an actual public health problem. This is due to rapid mutations of bacteria when exposed to antibiotics. In this case, beta-lactamases are enzymes used by bacteria to hydrolyze the beta-lactam rings present in the antibiotics. Therefore, it was necessary to explore novel molecules as potential beta-lactamases inhibitors to find antibacterial compounds against infection caused by ESBLs. …

Faculty Publications

Catfish are the predominant U.S. aquacultural product. However, byproducts from filleting, including bones that are high in calcium, typically go to waste or are sold as a low-valued feed. This research evaluated the potential use of catfish bone powder (CBP; 21.07% calcium) as a food ingredient. Catfish fillet strips were dredged with a breading mix (CBPM) containing 0% (0CBPM), 10% (10CBPM), and 20% (20CBPM) CBP before frying. Consumers (N = 211) evaluated sensory liking (nine-point hedonic scale) and attribute intensity (JAR scale), emotions (check-all-that-apply), and purchase intent (PI, yes/no) of samples. Color and texture were measured instrumentally. CBP did not …


Interpretation And Inference For Altmetric Indicators Arising From Sparse Data Statistics, Lawrence Smolinsky, Bernhard Klingenberg, Brian D. Marx Feb 2022

Interpretation And Inference For Altmetric Indicators Arising From Sparse Data Statistics, Lawrence Smolinsky, Bernhard Klingenberg, Brian D. Marx

Faculty Publications

In 2018 Bornmann and Haunschild (2018a) introduced a new indicator called the Mantel-Haenszel quotient (MHq) to measure alternative metrics (or altmetrics) of scientometric data. In this article we review the Mantel-Haenszel statistics, point out two errors in the literature, and introduce a new indicator. First, we correct the interpretation of MHq and mention that it is still a meaningful indicator. Second, we correct the variance formula for MHq, which leads to narrower confidence intervals. A simulation study shows the superior performance of our variance estimator and confidence intervals. Since MHq does not match its original description in the literature, we …

Preemption & Gender & Racial (In)Equity: Why State Tort Law Is Needed In The Cosmetic Context, Marie C. Boyd Feb 2022

Preemption & Gender & Racial (In)Equity: Why State Tort Law Is Needed In The Cosmetic Context, Marie C. Boyd

Faculty Publications

Much of the legal scholarship on the preemption of state tort law in the food and drug context and beyond has focused on issues of federalism. While the literature has considered the relationship between state tort law and the regulatory system, it has not generally explored the impact the federal preemption of state tort law may have on women and people of color. Similarly, while the literature has grappled with gender and racial justice issues in the tort system, including in the context of tort reform, it has largely not examined the gender and racial equity issues raised by federal …

Exploring Pre-Service Teachers’ Perspectives: Gender And Gender Representation Across Human Protagonists In Picture Books, Taraneh Matloob Haghanikar, Shan Jiang, Sara Tomek, Lisa M. Hooper

Faculty Publications

Gender is ever present in education preparation, school materials, curriculum, and school systems. To improve our knowledge about different facets of gender and the extent to which the depiction of gender has changed over time in picture books, there is a need to dig beneath the surface of questions about gender representation in picture books. Given that in-service teachers have proximity to approximately 75 million K-12 students, how in-service teachers think about gender, gender representation, and their own experiences with gender socialization have important implications on how K-12 students think, act, and feel about gender. In this study, we focused …

Dispersed Crude Oil Induces Dysbiosis In The Red Snapper Lutjanus Campechanus External Microbiota, Andrew M. Tarnecki, Christelle Miller, Tracy A. Sherwood, Robert J. Griffitt, Ryan W. Schloesser, Dana L. Wetzel

Faculty Publications

The fish external microbiota competitively excludes primary pathogens and prevents the proliferation of opportunists. A shift from healthy microbiota composition, known as dysbiosis, may be triggered by environmental stressors and increases host susceptibility to disease. The Deepwater Horizon (DWH) oil spill was a significant stressor event in the Gulf of Mexico. Despite anecdotal reports of skin lesions on fishes following the oil spill, little information is available on the impact of dispersed oil on the fish external microbiota. In this study, juvenile red snapper (Lutjanus campechanus) were exposed to a chemically enhanced water-accommodated fraction (CEWAF) of Corexit 9500/DWH …

Reassessing The Role Of Anthropogenic Climate Change In The Extinction Of Silphium, Paul Pollaro, Paul Robertson Jan 2022

Reassessing The Role Of Anthropogenic Climate Change In The Extinction Of Silphium, Paul Pollaro, Paul Robertson

Faculty Publications

The famed ancient herb, known to the Romans as silphium (Greeksilphion), is widely regarded as the first recorded instance of human-induced species extinction. Modern scholars have largely credited direct exploitation (e.g., over-harvesting; over-grazing) as the primary cause of silphium's extinction, due to an overwhelming demand for the plant in ancient times. Recent research has revealed strict cold-stratification requirements for the germination of silphium's closest living relatives, revealing the likelihood that silphium shared these same germination requirements. Documented environmental changes in ancient Cyrenaica (e.g., widespread deforestation; cropland expansion) likely resulted in accelerated rates of desertification throughout the region as well as …


Surface Acoustic Wave (Saw) Sensors: Physics, Materials, And Applications, Debdyuti Mandal, Sourav Banerjee Jan 2022

Surface Acoustic Wave (Saw) Sensors: Physics, Materials, And Applications, Debdyuti Mandal, Sourav Banerjee

Faculty Publications

Surface acoustic waves (SAWs) are the guided waves that propagate along the top surface of a material with wave vectors orthogonal to the normal direction to the surface. Based on these waves, SAW sensors are conceptualized by employing piezoelectric crystals where the guided elastodynamic waves are generated through an electromechanical coupling. Electromechanical coupling in both active and passive modes is achieved by integrating interdigitated electrode transducers (IDT) with the piezoelectric crystals. Innovative meta-designs of the periodic IDTs define the functionality and application of SAW sensors. This review article presents the physics of guided surface acoustic waves and the piezoelectric materials …


Effect Of Defects Part I: Degradation Of Constitutive Coefficients As An Input To The Composite Failure Model With Microvoids And Porosity, Vahid Tavaf, Sourav Banerjee Jan 2022

Effect Of Defects Part I: Degradation Of Constitutive Coefficients As An Input To The Composite Failure Model With Microvoids And Porosity, Vahid Tavaf, Sourav Banerjee

Faculty Publications

It is always challenging to provide appropriate material properties for a composite progressive failure model. The nonstandard percentage reduction method that is commonly used to degrade the material constants with micro-scale defects generates tremendous uncertainty in failure prediction. The constitutive matrix is composed of multiple material constants. It is not necessary that all constants degrade either equally or linearly due to a certain state of material defects. With this very concern in mind, this article presents a guideline for using a quantified perturbation for each coefficient appropriately. It also presents distribution of effective material properties (EMPs) in unidirectional composite materials …

Microplastics Through The Lens Of Colloid Science, Ahmed Al Harraq, Bhuvnesh Bharti Jan 2022

Microplastics Through The Lens Of Colloid Science, Ahmed Al Harraq, Bhuvnesh Bharti

Faculty Publications

Microplastics are sub-millimeter-sized fragments of plastics and a relatively new class of pollutant increasingly found in the environment. Due to their size and surface area to volume ratio, the physicochemical characteristics of microplastics can diverge from those of their macroscopic counterparts. This is partly why it is challenging to understand their origin, analyze their behavior, and predict their fates in the environment compared to large pollutants. We believe that adopting a view of microplastics as a colloid provides a holistic framework that connects their physical properties and surface chemistries with observations of their dynamics in the environment. In particular, we …

Too Much Is Never Enough: Constructing Electricity Market Demand, Todd S. Aagaard, Andrew N. Kleit Jan 2022

Too Much Is Never Enough: Constructing Electricity Market Demand, Todd S. Aagaard, Andrew N. Kleit

Faculty Publications

Some regions of the United States have created institutions known as capacity markets in an effort to use competitive market forces to ensure adequate electricity supply at lowest cost. But capacity markets are driven more by political and bureaucratic judgments than by competition. The manner in which the capacity market is designed to determine demand exemplifies this observation. As there is no natural demand for capacity, Regional Transmission organizations (RTOs) administratively create demand in capacity markets. RTOs derive capacity demand from three components: the capacity requirement based on forecasted peak demand plus an additional margin, the net cost of new …
