A Functional Near-Infrared Spectroscopic Investigation Of Speech Production During Reading, Nick Wan, Allison S. Hancock, Todd K. Moon, Ronald B. Gillam

Psychology Faculty Publications

This study was designed to test the extent to which speaking processes related to articulation and voicing influence Functional Near Infrared Spectroscopy (fNIRS) measures of cortical hemodynamics and functional connectivity. Participants read passages in three conditions (oral reading, silent mouthing, and silent reading) while undergoing fNIRS imaging. Area under the curve (AUC) analyses of the oxygenated and deoxygenated hemodynamic response function concentration values were compared for each task across five regions of interest. There were significant region main effects for both oxy and deoxy AUC analyses, and a significant region x task interaction for deoxy AUC favoring the oral reading …

The Relationship Between Restricted, Repetitive Behavior And Anxiety In Adults With Intellectual Disability, Casey M. Mazzola

Theses

This study investigated the relationship between restricted, repetitive behavior (RRB) and anxiety in a sample of adults with intellectual disability (ID). Six regression analyses were conducted. Predictor variables were age, severity of autism spectrum disorder (ASD) symptoms, level of adaptive functioning, and anxiety; RRB (in general and specific subtypes) was the criterion. Together, the four predictor variables accounted for a significant proportion of the variance in total RRB, Stereotypic Behavior, Compulsive Behavior, Ritualistic/Sameness Behavior, and Restricted Interests. Self-injurious behavior (SIB) was the only subtype of RRB in which the results of the regression analysis were not significant. Anxiety was found …

Dna Base Excision Repair And Double Strand Break Repair In Human Fibroblast, Mingyang Li

LSU Doctoral Dissertations

In eukaryotes, DNA repair mechanisms detect and repair damaged DNA. DNA damage is primarily caused by a variety of exogenous and endogenous sources. Several types of damage to DNA are repaired by different kinds of DNA repair pathways. This dissertation focused on repair of N-methylpurines (NMPs) and double-strand breaks (DSBs) in human fibroblasts.

NMPs, including N⁷-methylguanine (7MeG) and N³-methyladenine (3MeA), can be induced by environmental methylating agents (e.g. the soil fumigant methyl bromide), chemotherapeutics (e.g. nitrogen mustards), and natural cellular methyl donors like S-adenosylmethionine. In human cells, NMPs are repaired by the multi-step …

Algorithm For Computational Imaging On A Real-Time Hardware, Manish Bhattarai

Electrical and Computer Engineering ETDs

DRAMATIC advances in the field of computational and medical imaging over the past decades have enabled many critical applications such as night vision, medical diagnosis, quality control, and remote sensing. The increasing demand for image quality and its fidelity requires an increase in pixel count and a sophisticated post-processing mechanism to efficiently store, transmit, and analyze this massive data. There is an inherent trade-off between the generation of big data by such imaging systems and efficiency in extraction of useful information within real-time constraints, limiting the efficacy of such sensors in real-time decision-making systems. The traditional imaging system gets burdened …

Virtually Passing Monitor Detection Pulse Over Software Due To Hardware Constraints, Akanksha Gupta, Edward Anthony Mccreary, Alex Olson

Defensive Publications Series

During normal DisplayPort^TM operation, a cable connects from the Sink (monitor) to the Source directly via physical DisplayPort pins. But, what happens when Sink is connected to an Intermediary Device (ID) that connects to the Source? The straightforward approach is to transfer DisplayPort signals from Intermediary Device (ID) to the Source by hard-wiring all DisplayPort signals between them. This approach could be challenging if enough hardware pins are not available to send all the DisplayPort signals across from Intermediary Device to Source.

Thus, the idea disclosed in this disclosure demonstrates a way to successfully transfer all DisplayPort signals using …

From Play To Performance: Building An Effective Organization, Jessica N. Selee, Jade Johnson, Jocelyn N. Murray, Anna Samuelson, Jasmine Li, Andrew Lacanienta, Mat D. Duerden, Mark Widmer

Marriott Student Review

Under the Mentored Experience Grant, six students studies the impact that non-work activities (recreation or leisure) have on individual contributors or organization. Some employees refrain from participating in Leisure-at-Work (LAW) due to lack of time or skill, to cliques, to differing preferences, or fear of negative connotations. Employees report that LAW increases productivity, establishes and enriches social interactions, improves communication, attracts and retains employees in a company, and facilitates a culture of engagement, trust, and camaraderie. At the conclusion of our analysis, we identified areas of future research and recommendations for best practice.

The Blurred Line Between Photic And Aphotic Environments: A Large Mexican Cave With Almost No Dark Zone, Luis M. Mejía-Ortíz, Tanja Pipan, David C. Culver, Peter Sprouse

International Journal of Speleology

Sistema Muévelo Rico is a 1.2 km long cave in Quintana Roo, less than 2 km from the Caribbean Sea. We measured illuminance to a level of 0.1 lux, organic matter (weight loss on ignition), temperature, and relative humidity. The last two were measured at hourly intervals for nearly one year. Approximately one-third of the cave has illuminance values greater than 0.01 lux, and most of the rest of the cave has light as well. Temperature and relative humidity were relatively constant, but they showed a daily cycle at all stations, albeit with different strengths. Organic matter averaged 8%, intermediate …

Defensive Publications Series

An omni-directional catadioptric acquisition system (ODCA system) is provided to address the problem of producing real time, 360°, stereoscopic video of remote events for virtual reality (VR) viewing. The ODCA system is a video image-capture assembly that includes a cylinder with multiple apertures arranged around its circumference to admit light as the ODCA system rotates about a central axis. Inside the cylinder, there is a mirror on the left and right side of each aperture that reflects light rays into the cylinder from different angles. As the cylinder rotates, the light rays are admitted through the apertures and reflected from …

Redirected Walking For Cord Management, Josh Weaver

Defensive Publications Series

A player immersed in a virtual reality environment often interacts with a virtual reality scene while he is physically located in a virtual reality room. The player typically views the scene through a head-mounted display, which is connected to a host device or a network port via a communicative cord. When interacting with the virtual reality scene, the player may physically change and rotate his position in the virtual reality room in response to what is being displayed as part of the virtual reality scene. As a result, the communicative cord can wrap around and become entangled with itself or …

Speciation of copper in marine systems strongly influences the ability of copper to cause toxicity. Natural organic matter (NOM) contains many binding sites which provides a protective effect on copper toxicity. The purpose of this study was to characterize copper binding with NOM using fluorescence quenching techniques. Fluorescence quenching of NOM with copper was performed on nine sea water samples. The resulting stability con- stants and binding capacities were consistent with literature values of marine NOM, show- ing strong binding with log K values from 7.64 to 10.2 and binding capacities ranging from 15 to 3110 nmole mg C ^{−1 …}

Orbital Misalignment Of The Neptune-Mass Exoplanet Gj 436b With The Spin Of Its Cool Star, Vincent Bourrier, Christophe Lovis, Hervé Beust, David Ehrenreich, Gregory W. Henry, Nicola Astudillo-Defru, Romain Allart, Xavier Bonfils, Damien Ségransan, Xavier Delfosse, Heather M. Cegla, Aurélien Wyttenbach, Kevin Heng, Baptiste Lavie, Francesco Pepe

Information Systems and Engineering Management Research Publications

The angle between the spin of a star and the orbital planes of its planets traces the history of the planetary system. Exoplanets orbiting close to cool stars are expected to be on circular, aligned orbits because of strong tidal interactions with the stellar convective envelope. Spin–orbit alignment can be measured when the planet transits its star, but such ground-based spectroscopic measurements are challenging for cool, slowly rotating stars. Here we report the three-dimensional characterization of the trajectory of an exoplanet around an M dwarf star, derived by mapping the spectrum of the stellar photosphere along the chord transited by …

Coping With Behavioral Symptoms Of Dementia: Educating Caregivers To Lower Stress, Amber Aguilar

Doctor of Nursing Practice (DNP) Projects

Dementia is becoming increasing more prevalent as individual’s age. More than half of caregivers for patients with dementia rate the emotional stress of caregiving as high or very high (Alzheimer’s Association, 2016). Chronic stress can leads to caregiver fatigue, burnout, irritability and depression (Alzheimer’s Association, 2016). Recognizing stress may help improve the caregiver-patient relationship. The Progressively Lowered Stress Threshold (PLST) model is recommended as a framework for devising non-pharmacological interventions for persons with dementia across living environments (Buckwalter, 1987 & Coon et al, 2012). The purpose of this scholarly project is to conduct a review of the literature to understand …

Orientation Dependence Of Temporal And Spectral Properties Of High-Order Harmonics In Solids, Mengxi Wu, Yongsing You, Shambhu Ghimire, David A. Reis, Dana A. Browne, Kenneth J. Schafer, Mette B. Gaarde

Faculty Publications

We investigate the connection between crystal symmetry and temporal and spectral properties of high-order harmonics in solids. We calculate the orientation-dependent harmonic spectrum driven by an intense, linearly polarized infrared laser field, using a momentum-space description of the generation process in terms of strong-field-driven electron dynamics on the band structure. We show that the orientation dependence of both the spectral yield and the subcycle time profile of the harmonic radiation can be understood in terms of the coupling strengths and relative curvatures of the valence band and the low-lying conduction bands. In particular, we show that in some systems this …

Tiled Time Delay Estimation In Mobile Cloud Computing Environments, Ruairí De Fréin

Conference papers

We present a tiled delay estimation technique in the context of Mobile Cloud Computing (MCC) environments. We examine its accuracy in the presence of multiple sources for (1) sub-sample delays and also (2) in the presence of phase-wrap around. Phase wrap-around is prevalent in MCC because the separation of acoustic sources may be large. We show that tiling a histogram of instantaneous phase estimates can improve delay estimates when phase-wrap around is sig- nificantly present and also when multiple sources are present. We report that error in the delay estimator is generally less than 5% of a sample, when the …
