Department of Physics and Astronomy: Faculty Publications

Electrical modulation of magnetic states in single-phase multiferroic materials, using domain-wall magnetoelectric (ME) coupling, can be enhanced substantially by controlling the population density of the ferroelectric (FE) domain walls during polarization switching. In this work, we investigate the domain-wall ME coupling in multiferroic h-YbFeO₃ thin films, in which the FE domain walls induce clamped antiferromagnetic (AFM) domain walls with reduced magnetization magnitude. Simulation according to the phenomenological theory indicates that the domain-wall ME effect is dramatically enhanced when the separation between the FE domain walls shrinks below the characteristic width of the clamped AFM domain walls during the ferroelectric …

Department of Chemistry: Faculty Publications

Studying protein structures and dynamics directly in the cellular environments in which they function is essential to fully understand the molecular mechanisms underlying cellular processes. Site-directed spin-labeling (SDSL)—in combination with double electron–electron resonance (DEER) spectroscopy—has emerged as a powerful technique for determining both the structural states and the conformational equilibria of biomacromolecules. In-cell DEER spectroscopy on proteins in mammalian cells has thus far not been possible due to the notable challenges of spin-labeling in live cells. In-cell SDSL requires exquisite biorthogonality, high labeling reaction rates and low background signal from unreacted residual spin label. While the bioorthogonal reaction must be …

The Constitutional Model Of Mootness, Tyler B. Lindley

BYU Law Review

Article III limits the federal courts to deciding cases and controversies, and this limitation has given rise to the black-letter law of standing, ripeness, and mootness. But the law of mootness presents a puzzle: Over time, the Court has recognized various "exceptions" to ordinary mootness rules, allowing federal courts to hear arguably moot cases. On one hand, the Court consistently asserts that mootness doctrine, including its exceptions, is compelled by the original understanding of Article III. On the other hand, the scholarly consensus is that these exceptions are logically inconsistent with the Court s claims about Article III and that …

Visual Literacy Of Molecular Biology Revealed Through A Card-Sorting Task, Dina L. Newman, Hannah Spector, Anna Neuenschwander, Anna J. Miller, Lauren Trumpore, Leslie Kate Wright

Articles

Visual literacy, which is the ability to effectively identify, interpret, evaluate, use, and create images and visual media, is an important aspect of science literacy. As molecular processes are not directly observable, researchers and educators rely on visual representations (e.g., drawings) to communicate ideas in biology. How learners interpret and organize those numerous diagrams is related to their underlying knowledge about biology and their skills in visual literacy. Furthermore, it is not always obvious how and why learners interpret diagrams in the way they do (especially if their interpretations are unexpected), as it is not possible to “see” inside the …

Waste-Derived Hybrid Nanocomposite For The Simultaneous Removal Of Antibiotics And Dyes From Water Bodies, Abdelkader Ahmed

Theses and Dissertations

A novel eco-friendly approach was used to synthesize a hydroxyapatite-carbon nanocomposite (HAP-C) by utilizing the industrial waste of cement kiln dust (CKD) as a source of calcium for the synthesis. Citric acid was first used to chelate the calcium from CKD, then the chelate was converted into a mixture of calcium carbonate and carbon by calcination at 450°C for 1 h. The mixture was used as a precursor for the synthesis of HAP-C by reacting it with ortho-phosphoric acid via a precipitation method. HAP-C was then calcined at different temperatures of 400, 500, and 700°C under inert atmosphere, with a …

Skeleton-Based Hand Gesture Recognition Using Data-Level Fusion, Oluwaleke Yusuf

Theses and Dissertations

Hand Gesture Recognition (HGR) is a form of perceptual computing that allows artificial systems to capture and interpret human gestures. HGR has applications in human-machine interaction, virtual reality, augmented reality, and human behavior analysis. The human hand can assume a near-infinite number of poses and orientations to form myriad gestures, thus increasing the difficulty of the HGR task.

The hand skeleton of connected joints effectively describes the hand’s geometric shape and thus contains richer semantic gesture information while eliminating noise from individual differences in physical hand characteristics. The efficacy and computational efficiency of skeleton-based HGR frameworks can be significantly enhanced …

Normalized Coordinate Equations And Energy Method For Predicting Natural Curved-Fold Configurations, Jacob Badger, Todd G. Nelson, Rober J. Lang, Denise M. Halverson, Larry L. Howell

Faculty Publications

Of the many valid configurations that a curved fold may assume, it is of particular interest to identify natural—or lowest energy—configurations that physical models will preferentially assume. We present normalized coordinate equations—equations that relate fold surface properties

to their edge of regression—to simplify curved-fold rela- tionships. An energy method based on these normalized

coordinate equations is developed to identify natural con- figurations of general curved folds. While it has been noted

that natural configurations have nearly planar creases for curved folds, we show that non-planar behavior near the crease ends substantially reduces the energy of a fold.
