Auditory Fatigue Model Applications To Predict Noise Induced Hearing Loss In Human And Chinchilla, Pengfei Sun, Daniel Fox, Kathleen Campbell, Jun Qin

Articles

Noise induced hearing loss (NIHL) remains a severe health problem worldwide. Current noise metrics and models have assessment limitations on gradually developing NIHL (GDNIHL). In this study, we apply a complex velocity level (CVL) auditory fatigue model to quantitatively assess the impact of basilar membrane (BM) movement on GDNIHL. The transfer functions of chinchilla and human auditory systems, including the triple-path nonlinear (TRNL) filters to simulate the inner ear responses, are applied to obtain BM velocity distribution. Chinchilla and human experimental hearing loss data are used to validate the proposed CVL model’s effectiveness. The results reveal that the developed CVL …

Federal Involvement In Education Policy: An Analysis Of Race To The Top, Angela L. Early

Dissertations

The purpose of this study is to trace federal involvement in public K-12 education policy and to determine its effectiveness. Specifically, I present a historical analysis of federal education policy leading to the passage of Race to the Top (RTTT) in 2009. My goal is to show that, although the federal government has grown more involved in education policy, especially from the late 1980s (following the 1983 publication of A Nation At Risk that showed the failings of the nation’s schools) until present, actually students in the K-12 public education system have not progressed as the federal government had hoped. …

New Open Conformation Of Smyd3 Implicates Conformational Selection And Allostery, Nicholas Spellmon, Xiaonan Sun, Wen Xue, Joshua Holcomb, Srinivas Chakravarthy, Weifeng Shang, Brian Fp Edwards, Nualpun Sirinupong, Chunying Li, Zhe Yang

Biochemistry and Molecular Biology Faculty Publications

SMYD3 plays a key role in cancer cell viability, adhesion, migration and invasion. SMYD3 promotes formation of inducible regulatory T cells and is involved in reducing autoimmunity. However, the nearly “closed” substrate-binding site and poor in vitro H3K4 methyltransferase activity have obscured further understanding of this oncogenically related protein. Here we reveal that SMYD3 can adopt an “open” conformation using molecular dynamics simulation and small-angle X-ray scattering. This ligand-binding-capable open state is related to the crystal structure-like closed state by a striking clamshell-like inter-lobe dynamics. The two states are characterized by many distinct structural and dynamical differences and the conformational …

The Quantum Biology Of Reactive Oxygen Species Partitioning Impacts Cellular Bioenergetics, Robert J. Usselman, Cristina Chavarriaga, Pablo R. Castello, Maria Procopio, Thorsten Ritz, Edward A. Dratz, David John Singel, Carlos F. Martino

Biomedical Engineering and Sciences Faculty Publications

Quantum biology is the study of quantum effects on biochemical mechanisms and biological function. We show that the biological production of reactive oxygen species (ROS) in live cells can be influenced by coherent electron spin dynamics, providing a new example of quantum biology in cellular regulation. ROS partitioning appears to be mediated during the activation of molecular oxygen (O2) by reduced flavoenzymes, forming spin-correlated radical pairs (RPs). We find that oscillating magnetic fields at Zeeman resonance alter relative yields of cellular superoxide (O2•−) and hydrogen peroxide (H2O2) ROS products, indicating coherent singlet-triplet mixing at the point of ROS formation. Furthermore, …

Continued Study On Finite Element Models Of Flagella, Gary Hu, Philip V. Bayly

Mechanical Engineering and Materials Science Independent Study

In previous study, we developed finite element models of flagella that show wavelike oscillation above certain load threshold. However, these baseline models were highly simplified and had inevitable limitations. In the current study, inter-doublet components have been meshed with finer setting to give more accurate results, multibody dynamics (translational joints) has introduced to allow more deflection, and inter-doublet materials have included viscoelasticity. Nondimensional waveform equations have been developed to find parameter values that allow larger deflection and frequencies close to actual cilia and flagella.

Comparative Genetic Screens In Human Cells Reveal New Regulatory Mechanisms In Wnt Signaling, Andres M. Lebensohn, Ramin Dubey, Leif Neitzel, Ofelia Tacchelly-Benites

Dartmouth Scholarship

The comprehensive understanding of cellular signaling pathways remains a challenge due to multiple layers of regulation that may become evident only when the pathway is probed at different levels or critical nodes are eliminated. To discover regulatory mechanisms in canonical WNT signaling, we conducted a systematic forward genetic analysis through reporter-based screens in haploid human cells. Comparison of screens for negative, attenuating and positive regulators of WNT signaling, mediators of R-spondin-dependent signaling and suppressors of constitutive signaling induced by loss of the tumor suppressor adenomatous polyposis coli or casein kinase 1α uncovered new regulatory features at most levels of the …

The results showed that TSKgel®Amide-80 exhibited a better performance than other polar stationary phases in carbofuran determination, and observations …

Mass Reduction Patterning Of Silicon-On-Oxide–Based Micromirrors, Harris J. Hall, Andrew Green, Sarah Dooley, Jason D. Schmidt, Lavern A. Starman, Derrick Langley, Ronald A. Coutu Jr.

Electrical and Computer Engineering Faculty Research and Publications

It has long been recognized in the design of micromirror-based optical systems that balancing static flatness of the mirror surface through structural design with the system’s mechanical dynamic response is challenging. Although a variety of mass reduction approaches have been presented in the literature to address this performance trade, there has been little quantifiable comparison reported. In this work, different mass reduction approaches, some unique to the work, are quantifiably compared with solid plate thinning in both curvature and mass using commercial finite element simulation of a specific square silicon-on-insulator–based micromirror geometry. Other important considerations for micromirror surfaces, including surface …

Et Tu, Android?: Regulating Dangerous And Dishonest Robots, Woodrow Hartzog

Faculty Scholarship

Consumer robots like personal digital assistants, automated cars, robot companions, chore-bots, and personal drones raise common consumer protection issues, such as fraud, privacy, data security, and risks to health, physical safety, and finances. They also raise new consumer protection issues, or at least call into question how existing consumer protection regimes might be applied to such emerging technologies. Yet it is unclear which legal regimes should govern these robots and what consumer protection rules for robots should look like.

This paper argues that the FTC's grant of authority and existing jurisprudence are well-suited for protecting consumers who buy and interact …

Discontinuous Finite Element Mechanistic Water Quality Model For The Simulation Of Adsorptive Pollutants Transport In River Systems., F. P. Fiengo, L. Sweeck, M. Elskens, W. Bauwens

Open Water Journal

The close interaction between humans, animals and the river system requires to have control about the concentration of different pollutants in the water column in order to avoid damage to the environment. Due to the fact that the measurements are time consuming, expensive and in most of the cases very local, it is required to develop tools in order to predict the spatial and temporal distribution of the pollutants in the system.

Once pollutant effluents are discharged in waters, part of them is transported in liquid phase and the rest is attached to the suspended sediments and to the bed …

H2pl: A New Open Source Library For Hydrological Modeling, Khodayar Abdollahi, Okke Batelaan, Marijke Huysmans

Open Water Journal

Due to spatial and temporal variation of hydrologic processes, development of distributed hydrological models remained a difficult task over the last decades. As a consequence application of Geographic Information Systems (GIS) has become a useful and popular tool not only for hydrology but also in many different fields of science. On the other hand, literature emphasizes that hydrological modelers use GIS blindly but should take the advantage of advances in computing technology. This issue generates a demand for development of hydrological frameworks to conceptualize time and space models which targets hydrological modeling specifically.

This study presents the development of an …
