Wedge Domains In Compactly Causal Symmetric Spaces, Karl Hermann Neeb, Gestur Ólafsson

Faculty Publications

Motivated by constructions in Algebraic Quantum Field Theory we introduce wedge domains in compactly causal symmetric spaces M = G/H, which includes in particular anti-de Sitter space in all dimensions and its coverings. Our wedge domains generalize Rindler wedges in Minkowski space. The key geometric structure we use is the modular flow on M defined by an Euler element in the Lie algebra of G. Our main geometric result asserts that three seemingly different characterizations of these domains coincide: the positivity domain of the modular vector field, the domain specified by a KMS-like analytic extension condition for the modular flow, …

Aims. We inspect the four microlensing events KMT-2021-BLG-1968, KMT-2021-BLG-2010, KMT-2022-BLG-0371, and KMT-2022-BLG-1013, for which the light curves exhibit partially covered short-Term central anomalies. We conduct detailed analyses of the events with the aim of revealing the nature of the anomalies. Methods. We tested various models that can explain the anomalies of the individual events, including the binary-lens (2L1S) and binary-source (1L2S) interpretations. Under the 2L1S interpretation, we thoroughly inspected the parameter space to determine the existence of degenerate solutions, and if they existed, we tested whether the degeneracy could be resolved. Results. We find that the anomalies in KMT-2021-BLG-2010 and …

8(Meso)-Pyridyl-Bodipys: Effects Of 2,6-Substitution With Electron-Withdrawing Nitro, Chloro, And Methoxycarbonyl Groups, Caroline Ndung’U, Petia Bobadova-Parvanova, Daniel J. Lamaster, Dylan Goliber, Frank R. Fronczek, Maria Da Graça H. Vicente

Faculty Publications

The introduction of electron-withdrawing groups on 8(meso)-pyridyl-BODIPYs tends to increase the fluorescence quantum yields of this type of compound due to the decrease in electronic charge density on the BODIPY core. A new series of 8(meso)-pyridyl-BODIPYs bearing a 2-, 3-, or 4-pyridyl group was synthesized and functionalized with nitro and chlorine groups at the 2,6-positions. The 2,6-methoxycarbonyl-8-pyridyl-BODIPYs analogs were also synthesized by condensation of 2,4-dimethyl-3-methoxycarbonyl-pyrrole with 2-, 3-, or 4-formylpyridine followed by oxidation and boron complexation. The structures and spectroscopic properties of the new series of 8(meso)-pyridyl-BODIPYs were investigated both experimentally and computationally. The BODIPYs bearing 2,6-methoxycarbonyl groups showed enhanced …

The Everydayness Of Instructional Design And The Pursuit Of Quality In Online Courses, Jason K. Mcdonald

Faculty Publications

This article reports research into the everydayness of instructional design (meaning designers’ daily routines, run-of-the-mill interactions with colleagues, and other, prosaic forms of social contact), and how everydayness relates to their pursuit of quality in online course design. These issues were investigated through an ethnographic case study, centered on a team of instructional designers at a university in the United States. Designers were observed spending significant amounts of time engaged in practices of course refinement, meaning mundane, workaday tasks like revising, updating, fine-tuning, or fixing the courses to which they were assigned. Refining practices were interrelated with, but also experienced …

Development Of Gluten-Free Bread Using Teosinte (Dioon Mejiae) Flour In Combination With High-Protein Brown Rice Flour And High-Protein White Rice Flour, Franklin Delarca Ruiz, Ricardo S. Aleman, Shirin Kazemzadeh Pournaki, Mallerly Sarmiento Madrid, Andrea Muela, Yeimi Mendoza, Jhunior Marcia Fuentes, Witoon Prinyawiwatkul, Joan M. King

Faculty Publications

Gluten-free bread is an important product that is under development using different sources, such as rice and starchy plants. Teosinte seeds are utilized by ethnic groups in Honduras to produce gluten-free flour to prepare traditional baked goods and beverages. The quality of gluten-free products could vary depending on flour properties, such as amylose content, particle size, and water absorption capacity. A good strategy for developing baked goods is to mix different cereal grain sources to optimize their physicochemical properties. As a result, the current study aimed to develop bread from novel flours including teosinte (TF), high-protein brown rice (BRF), and …

Preventing Vicarious Trauma And Encouraging Self-Care In Clinical Legal Teaching, Deeya Haldar, Sarah Katz

Faculty Publications

Vicarious trauma, sometimes called “compassion fatigue” or “secondary trauma,” is a term for the effect that working with survivors of trauma may have on counselors, therapists, doctors, attorneys, and others who directly help them. Vicarious traumatisation refers to harmful changes that occur in professionals’ views of themselves, others, and the world as a result of exposure to the graphic or traumatic experiences of their clients. While it is unusual for law students to experience vicarious trauma in a clinical legal education setting, there are good reasons to introduce the concept of vicarious trauma and measures to prevent vicarious trauma through …

Thermoset Polymer Composites With Gradient Natural And Synthetic Fiber Reinforcement: Self-Healing, Shape-Memory, And Fiber Recyclability, Sakil Mahmud, John Konlan, Jenny Deicaza, Rachel Anna Schmidt, Guoqiang Li

Faculty Publications

Natural fibers have high potential as renewable reinforcement for polymers; however, their lower load-carrying capacity compared to synthetic fibers significantly limits the wide application in fiber-reinforced polymer composites. In laminated composite beams under bending load, the normal stress is the highest on the top and bottom layers but is zero at the mid-plane, with almost a linear normal strain distribution. Although the shear stress is the highest at the mid-plane, it may not be a major concern as most polymers can survive the high shear stress. Using this concept, we have designed a hybrid fiber reinforcement in a gradient manner: …

Faculty Publications

To inform the development of global wastewater monitoring systems, we surveyed programmes in 43 countries. Most programmes monitored predominantly urban populations. In high-income countries (HICs), composite sampling at centralised treatment plants was most common, whereas grab sampling from surface waters, open drains, and pit latrines was more typical in low-income and middle-income countries (LMICs). Almost all programmes analysed samples in-country, with an average processing time of 2·3 days in HICs and 4·5 days in LMICs. Whereas 59% of HICs regularly monitored wastewater for SARS-CoV-2 variants, only 13% of LMICs did so. Most programmes share their wastewater data internally, with partnering …

On The Characteristics Of Fatigue Fracture With Rapid Frequency Change, Mohammad A. Amooie, K. P. Lijesh, Ali Mahmoudi, Elaheh Azizian-Farsani, Michael M. Khonsari

Faculty Publications

The effect of sudden variations in working modes and fatigue behavior of CS 1018 is studied. A general model based on the framework of the fracture fatigue entropy (FFE) concept is developed to capture such changes. Fully reversed bending tests are performed on flat dog bone specimens with a series of variable frequency tests without turning the machine off to simulate fluctuating working conditions. The results are then post-processed and analyzed to assess how fatigue life changes when a component is subjected to sudden changes in multiple frequencies. It is demonstrated that regardless of the frequency changes, FFE remains constant …

Rapid Evaluation Of Fatigue Limit Using Energy Dissipation, Ali Mahmoudi, Michael M. Khonsari

Faculty Publications

Four different experimental approaches for rapid estimation of fatigue limit (endurance limit) based on energy dissipation during cyclic loading are discussed. The presented approaches use energy dissipation and thermography and can reliably evaluate the fatigue limit of material by conducting the fatigue test on a single specimen. Results show that the released energy due to damage accumulation at the stress levels above the fatigue limit changes the trend of energy dissipation and that this trend can be used to predict the fatigue limit. Experimental results on CS 1018 and SS 304 specimens are presented to illustrate the utility of the …

Single But Not Solitary: A Call For Nuance In The Study Emerging Adult Singlehood, Jonathon J. Beckmeyer, Tyler Jamison

Faculty Publications

Both research and theory demonstrate that single adults are not a homogeneous group. However, scholars continue to rely on participants to self-identify their relationship status from a list that includes multiple forms of romantic involvement (e.g., casual dating, committed relationship, engaged, married), but only one category of non-involvement: “single.” This approach is especially limiting when studying emerging adults, who are often exploring different forms of sexual and romantic engagement. Consequently, we developed a two-step approach that contextualizes singlehood through the romantic and sexual activities of self-reported single emerging adults. Across three samples of U.S. emerging adults, we found that about …

Modeling Potential Damages Of Hurricanes At The Facility Scale: A Case Study Of Eglin Air Force Base, Alexander J. Baldwin, Christopher M. Chini, Steven J. Schuldt, Justin D. Delorit

Faculty Publications

Tropical cyclones have intensified and are expected to strengthen throughout the 21st century due to climate change impacts. Storm intensification poses a serious threat to coastal municipalities and infrastructure that are not designed to withstand future wind and storm surge potential. Coupled modeling software has been widely used to replicate extreme weather events and simulate climate change effects to understand the magnitude of vulnerability coastal regions face. However, these studies are often conducted at too coarse resolutions to provide decision makers with actionable information for facility-level adaptation. This study addresses this limitation using a coupled modeling approach by simulating climate-intensified …

Nonsolvent-Induced Phase Separation Inside Liquid Droplets, Rami Alhasan, Tanner A. Wilcoxson, Dakota S. Banks, Sion Jung, Douglas R. Tree

Faculty Publications

Nonsolvent-induced phase separation (NIPS) is a popular method for creating polymeric particles with internal microstructure, but many fundamental questions remain surrounding the kinetics of the complex coupled mass transfer and phase separation processes. In this work, we use simulations of a phase-field model to examine how (i) finite domain boundaries of a polymer droplet and (ii) solvent/nonsolvent miscibility affect the NIPS process. To isolate the effects of phase separation kinetics and solvent/nonsolvent mass transfer on the NIPS process, we study two different cases. First, we investigate droplet concentrations that originate inside the two-phase region, where phase separation kinetics alone governs …

Informal Practices Of Localizing Open Educational Resources In Ghana, Emily Durham Bradshaw, Jason K. Mcdonald

Faculty Publications

Research on the use of Open Educational Resources (OER) often notes the potential benefits for users to revise, reuse, and remix OER to localize it for specific learners. However, a gap in the literature exists in terms of research that explores how this localization occurs in practice. This is a significant gap given the current flow of OER from higher-income countries in the Global North to lower-income countries in the Global South (King et al., 2018). This study explores how OER from one area of the world is localized when it is used in a different cultural context.

Misogynoir And The Public Woman: Analog And Digital Sexualization Of Women In Public From The Civil War To The Era Of Kamala Harris, Cecilia Cerja, Nicole D. Nave, Kelly L. Winfrey, Catherine Helen Palczewski, Leslie A. Hahner

Faculty Publications

This essay identifies how the very conception of public woman is infused with the opprobrium hurled against a wanton woman–a sexualized figure who has lost claims to moral standing or social worth. Our analysis begins diachronically by using thin description to trace the historical conflation of public woman in general, and Black woman in particular, with prostitute to outline the contours of the trope of public woman that have solidified across time. We document how the public woman became equated with prostitute, and then how the label prostitute was affixed to women in public to situate them as promiscuous or …
