Short Communication: Massive Erosion In Monsoonal Central India Linked To Late Holocene Land Cover Degradation, Liviu Giosan, Camilo Ponton, Muhammed Usman, Jerzy Glusztajn, Dorian Q. Fuller, Valier Galy, Negar Haghipour, Joel E. Johnson, Cameron Mcintyre, Lukas Wacker, Timothy I. Eglinton

Faculty Publications

Soil erosion plays a crucial role in transferring sediment and carbon from land to sea, yet little is known about the rhythm and rates of soil erosion prior to the most recent few centuries. Here we reconstruct a Holocene erosional history from central India, as integrated by the Godavari River in a sediment core from the Bay of Bengal. We quantify terrigenous fluxes, fingerprint sources for the lithogenic fraction and assess the age of the exported terrigenous carbon. Taken together, our data show that the monsoon decline in the late Holocene significantly increased soil erosion and the age of exported …

Analyzing Young Readers' Empathetic Responses To A Mexican American Historical Narrative, Yvette Rivera

Theses and Dissertations

Empathy and cultural understanding of groups that are marginalized due to religious, ethnic or sexual background is essential for peace in schools, neighborhoods, and society at large. Literacy classrooms can be a safe environment in which students can develop their own understandings and empathies. Although worthwhile, much of the research lacks details of student reactions to the people and cultures read about in historical narratives, as well as a focus on pedagogical practices that could give students a deep understanding of the culture. This study analyzed the empathetic responses of 13 sixth grade students to themes presented in a Mexican …

An Elevation Of 0.1 Light-Seconds For The Optical Jet Base In An Accreting Galactic Black Hole System, P. Gandhi, M. Bachetti, V. S. Dhillon, R. P. Fender, L. K. Hardy, F. A. Harrison, S. P. Littlefair, J. Malzac, S. Markoff, T. R. Marsh, K. Mooley, D. Stern, J. A. Tomsick, D. J. Walton, P. Casella, F. Vincentelli, D. Altamirano, J. Casares, C. Ceccobello, P. A. Charles, C. Ferrigno, R. I. Hynes, C. Knigge, E. Kuulkers, M. Pahari, F. Rahoui, D. M. Russell, A. W. Shaw

Faculty Publications

Relativistic plasma jets are observed in many systems that host accreting black holes. According to theory, coiled magnetic fields close to the black hole accelerate and collimate the plasma, leading to a jet being launched 1-3. Isolating emission from this acceleration and collimation zone is key to measuring its size and understanding jet formation physics. But this is challenging because emission from the jet base cannot easily be disentangled from other accreting components. Here, we show that rapid optical flux variations from an accreting Galactic black-hole binary are delayed with respect to X-rays radiated from close to the black hole …

Gradients In Wall Mechanics And Polysaccharides Along Growing Inflorescence Stems, Pyae Phyo, Tuo Wang, Sarah N. Kiemle, Hugh O’Neill, Sai Venkatesh Pingali, Mei Hong, Daniel J. Cosgrove

Faculty Publications

© 2017 American Society of Plant Biologists. All Rights Reserved. At early stages of Arabidopsis (Arabidopsis thaliana) flowering, the inflorescence stem undergoes rapid growth, with elongation occurring predominantly in the apical; 4 cm of the stem. We measured the spatial gradients for elongation rate, osmotic pressure, cell wall thickness, and wall mechanical compliances and coupled these macroscopic measurements with molecular-level characterization of the polysaccharide composition, mobility, hydration, and intermolecular interactions of the inflorescence cell wall using solid-state nuclear magnetic resonance spectroscopy and small-angle neutron scattering. Force-extension curves revealed a gradient, from high to low, in the plastic and elastic compliances …

Polyamorphic Transformations In Fe-Ni-C Liquids: Implications For Chemical Evolution Of Terrestrial Planets, Xiaojing Lai, Bin Chen, Jianwei Wang, Yoshio Kono, Feng Zhu

Faculty Publications

©2017. American Geophysical Union. All Rights Reserved. During the formation of the Earth's core, the segregation of metallic liquids from silicate mantle should have left behind evident geochemical imprints on both the mantle and the core. Some distinctive geochemical signatures of the mantle-derived rocks likely own their origin to the metal-silicate differentiation of the primitive Earth, setting our planet apart from undifferentiated meteorites as well as terrestrial planets or moons isotopically and compositionally. Understanding the chemical evolution of terrestrial planetary bodies requires knowledge on properties of both liquid iron alloys and silicates equilibrating under physicochemical conditions pertinent to the deep …

Comparison Of Five Methods For Parameter Estimation Under Taylor's Power Law, Peijian Shi, David A. Ratkowsky, Ningtao Wang, Yang Li, Lei Zhao, Gadi V.P. Reddy, Bai Lian Li

Faculty Publications

Taylor's power law (TPL) can be applied to the mean-variance relationship for various quantities, e.g., population densities over space and time, biomass of plants in the growth processes, developmental rates and growth rates of arthropods at different temperatures, etc. When TPL holds in the grouped data (e.g., the biomass of plants at different investigation times with limited replicates at each investigation), we must consider the heterocedasticity when carrying out the parameter estimation for a given mathematical model. We propose two new target functions based on TPL and attempt to more accurately estimate the model parameter(s). By capturing the mean-variance relationship, …

Challenges In Development Of Sperm Repositories For Biomedical Fishes: Quality Control In Small-Bodied Species, Leticia Torres, Yue Liu, Amy Guitreau, Huiping Yang, Terrence R. Tiersch

Faculty Publications

Quality control (QC) is essential for reproducible and efficient functioning of germplasm repositories. However, many biomedical fish models present significant QC challenges due to small body sizes (<5 >cm) and miniscule sperm volumes (<5 >μL). Using minimal volumes of sperm, we used Zebrafish to evaluate common QC endpoints as surrogates for fertilization success along sequential steps of cryopreservation. First, concentrations of calibration bead suspensions were evaluated with a Makler® counting chamber by using different sample volumes and mixing methods. For sperm analysis, samples were initially diluted at a 1:30 ratio with Hanks' balanced salt solution (HBSS). Motility was evaluated by …

Twenty Years Later: An Update To The Birds Of The Biological Dynamics Of Forest Fragments Project, Amazonas, Brazil, Cameron L. Rutt, Vitek Jirinec, Erik I. Johnson, Mario Cohn-Haft, Claudeir F. Vargas, Philip C. Stouffer

Faculty Publications

Although species lists from throughout Amazonia have become available, relatively complete inventories based on longterm work remain rare. Longitudinal comparisons at well-studied sites provide the best opportunities for describing communities and identifying changes in regional avifaunas. Within central Amazonia, no region has received as much consistent ornithological coverage as the terra firme forests north of Manaus, Brazil, at the Biological Dynamics of Forest Fragments Project (BDFFP). Here we provide an updated list of the area, including notes on all species added between 1997 and 2017. We recorded 21 species new for the site, most of which (>75%) are birds …

Faculty Publications

Approximately 65-75 days postpartum (dpp), the estrous cycles of nonlactating (dried off immediately postpartum: n = 12) and lactating (n = 13) Holstein Friesian cows were synchronized and on day 7 a single blastocyst derived from superovulated nulliparous Holstein Friesian heifers was transferred to each cow. A control group of nulliparous heifers (n = 8) were synchronized, inseminated to a standing heat, and slaughtered on the same day as nonlactating and lactating recipients (day 19; estrus = day 0). The uterine horn ipsilateral to the corpus luteum was flushed with 10 ml phosphate-buffered saline and the conceptus, and uterine luminal …

Genome-Wide Microarray Analysis Leads To Identification Of Genes In Response To Herbicide, Metribuzin In Wheat Leaves, Whitney Pilcher, Hana Zandkamiri, Kelly Arceneaux, Stephen Harrison, Niranjan Baisakh

Faculty Publications

Herbicides are an important component of weed management in wheat, particularly in the southeastern US where weeds actively compete with wheat throughout the winter for nutrients and reduce tillering and ultimately the yield of the crop. Some wheat varieties are sensitive to metribuzin, a low-cost non-selective herbicide, leading to leaf chlorosis, stand loss, and decreased yield. Knowledge of the genetics of herbicide tolerance in wheat is very limited and most new varieties have not been screened for metribuzin tolerance. The identification of genes associated with metribuzin tolerance will lead to the development of molecular markers for use in screening breeding …

The Impact Of Inappropriate Modeling Of Cross-Classified Data Structures On Random-Slope Models, Feifei Ye, Laura Daniel

Journal of Modern Applied Statistical Methods

Previous studies that explored the impact of misspecification of cross-classified data structure as strictly hierarchical are limited to random intercept models. This study examined the effects of misspecification of a two-level, cross-classified, random effect model (CCREM) where both the level-1 intercept and slope were allowed to vary randomly. Results suggest that ignoring one of the crossed factors produced considerably underestimated standard errors for: 1) the regression coefficients of the level-1 predictor; 2) the inappropriately modeled predictor associated with the misspecified crossed factor; and 3) and their interaction. This misspecification also resulted in a significant inflation of the level-1 residual variances …

Relative Importance Of Different Body Channels To The Believability Of A Stylized 3d Character Animation In A Full Body Shot, Saikiran Anasingaraju

Open Access Theses

Character animation involves movement in different channels of the character’s body. There is a norm in the animation industry that each of these different body channels has varying contributions to the believability of an acting performance: body movement being the highest contributor and lip sync the lowest. This thesis investigated this norm using statistical analysis. While the reduction of body motion caused the biggest drop in believability, similar reductions in facial animation and lip sync have not made a significant effect on the believability. The only exception to the above statement is the animation depicting the emotion sadness, where no …

Interactivity Factors In Visualization-Based Exploratory Search, Ali Baigelenov

Open Access Theses

Two of the main components of visualizations are representation and interaction. Several researchers have noted that the interaction component has been receiving less attention than the visual (representation) component. It was also noted by several researchers that there is currently no well-developed theoretical base for interaction research in information visualization. A number of important contributions to this problem were made, resulting in different frameworks that aimed to deal with various aspects of interaction design, such as benefits, costs, and techniques, to name a few. Despite the contributions and findings, the interactivity factors of diversity, complementarity, and fitness are still relatively …

Design Of A Twisting Multi-Stable Actuator, Aaron J. Anderson

Open Access Theses

Actuators based on compliant multi-stable structures o˙er bene˝ts of low mass, large stroke, high blocking force, and fast actuation response. The compliant structure eliminates friction and failure points inherent to actuators featuring joints and moving parts. These characteristics o˙er a large potential for application in ˝elds such as aerospace or robotics where they can be scaled and modi˝ed to ˝t many design scenarios. A class of twisting bi-stable structures lends itself for use in linear actuation, as linear displacement is created upon twisting. These structures are also capable of fast actuation via snap-through between stable twisted states. This paper considers …

Effects Of Dry-Aging On Eating Quality, Physicochemical, And Microbiological Attributes Of Grass-Fed Beef Loins, Jordy Berger

Open Access Theses

The United States has the greatest number of cattle on feed and is the largest producer of beef in the world (Jones, 2017). As a major contributor to the American economy, it is vital for the beef industry to provide consumers with high quality products that meet their expectations in order to ensure continued meat purchase (Schroeder and Mark, 2000). To accomplish these objectives, an understanding of beef eating quality attributes and ongoing research to identify how and what factors contribute to these attributes is essential. Beef palatability is assessed by the evaluation of tenderness, juiciness, and flavor (Reicks et …

Secondary Loop Residential Heat Pump Design, Performance, And Cost Analysis Utilizing R290, Tim Blatchley

Open Access Theses

The use of alternative refrigerants and HVAC technologies is necessary because of the inevitable phase out of current refrigerants. Ammonia and Propane are desirable for air conditioning applications because of their superior thermodynamic and transport properties compared to many HFC refrigerant alternatives. However, these refrigerants are toxic or flammable. The idea to use a secondary loop cycle enables these refrigerants to be used while not bringing them in contact with people. An initial analysis of a secondary loop system for a residential heat pump using propane as the refrigerant was performed using ACHP showing a comparable performance to a traditional …

Using Ultrasonic Speckle Velocimetry To Detect Fluid Instabilities In A Surfactant Solution, Jason E. Bice

Open Access Theses

Rheometry is a leading technology used to define material properties of multi-phase viscoelastic fluid-like materials, such as the shear modulus and viscosity. However, traditional rheometry relies on a mechanical response from a rotating or oscillating rotor of various geometries which does not allow for any spatial or temporal quantification of the material characteristics. Further, the setup operates under the assumption of a uniform and homogenous flow. Thus, only qualitative deductions can be realized when a complex fluid displays inhomogeneous behavior, such as wall slip or shear banding. Due to this lack of capability, nonintrusive imaging is required to define and …

Measuring Fatigue Crack Deflections Via Cracking Of Constituent Particles In Aa7050-T7451 Rolled Plate Via In-Situ X-Ray Synchrotron Computed Micro-Tomography, Stephen T. Carter
