Flowers Or Flora?: Understanding The Effects Of Probiotics On Depression, Nicole Collopy

Senior Theses

The human gut is populated with hundreds of types of bacteria and fungi. In North America, both intestinal and mood disorders are prevalent, presenting health problems that challenge health care professionals and patients alike. A scholarly literature review was conducted to explore this important relationship.

The investigation of the literature revealed that there is an association between gut health disorders and mood disorders, mainly anxiety and depression. This is due to bi-directionality between the brain-gut pathways, meaning that gastrointestinal health may have an effect on mental health and vice versa.

This connection between gut and mood can have substantial implications …

Genome-Wide Computational Identification Of Biologically Significant Cis-Regulatory Elements And Associated Transcription Factors From Rice, Chai-Ling Ho, Matt Geisler

Publications

The interactions between transcription factors (TFs) and cis-acting regulatory elements (CREs) provide crucial information on the regulation of gene expression. The determination of TF-binding sites and CREs experimentally is costly and time intensive. An in silico identification and annotation of TFs, and the prediction of CREs from rice are made possible by the availability of whole genome sequence and transcriptome data. In this study, we tested the applicability of two algorithms developed for other model systems for the identification of biologically significant CREs of co-expressed genes from rice. CREs were identified from the DNA sequences located upstream from the transcription …

Estimation Of Correlation Confidence Intervals Via The Bootstrap: Non-Normal Distributions, John Mart V. Delosreyes

Psychology Theses & Dissertations

Estimating confidence intervals (CIs) for the correlation has been a challenge. The challenge stems from the metamorphic nature of the sampling distribution of the correlation being bound by-1≤ρ≤1. The nonparametric nature of the bootstrap makes it a good option for estimating correlation CIs. However, there have been mixed results about the robustness of bootstrap CIs for the correlation with non normal data. This had led the literature to suggesting the use of transformation methods to estimate correlation CIs. However, transformation methods carry a risk of the original data being misrepresented. Thus, further investigation of bootstrap CIs for the correlation is …

Diagnostic Analysis Of Random Vibration Results In The Aviation Gas Turbine Enginespulse-Width Automatic Control Systems Based On Dynamic Graphs, G. Sh. Tuganov, C. M. Rakhimov, E. Norkulov

Technical science and innovation

Studies are often conducted to minimize the effect of vibration on equipment and its mechanisms. Since the engine is the main driving force of all technical objects, vibration is one of the factors hindering its operation. With this in mind, this article investigated the random probability distribution of vibration parameters using the laws of mathematical statistical distribution and was found to be compatible with the normal distribution law. At the same time, this study demonstrates that the proposed method of technical diagnostics can be used to assess helicopter engine failures.

High-Precision Radioisotopic Ages For The Lower Midian (Upper Wordian) Stage Of The Tethyan Time Scale, Shigeyasu Quarry, Yamaguchi Prefecture, Japan, V. I. Davydov, M. D. Schmitz

Geosciences Faculty Publications and Presentations

Global correlation of strata to the Guadalupian Series (Permian Period) of the International Geologic Time Scale remains provisional due to a lack of the sufficient biostratigraphically constrained radioisotopic ages. Five new high-precision U–Pb radioisotopic ages were obtained from tuffs in the lower Midian (upper Wordian) volcano-siliciclastic succession of the Akiyoshi Plateau, southwestern Japan. Two undisturbed and continuous tuffs occur within fusulinid-bearing laminated limestone turbidites, with precise biostratigraphic control. The Colania douvillei and Lepidolina shiraiwensis fusulinid Zones in the Akiyoshi succession provide an early Midian age in the Tethyan provincial time scale. The range of ages (267.46 ± 0.04 Ma to …

Low-Rank Sparse Subspace For Spectral Clustering, Xiaofeng Zhu, Shichao Zhang, Yonggang Li, Jilian Zhang, Lifeng Yang, Yue Fang

Research Collection School Of Computing and Information Systems

The current two-step clustering methods separately learn the similarity matrix and conduct k means clustering. Moreover, the similarity matrix is learnt from the original data, which usually contain noise. As a consequence, these clustering methods cannot achieve good clustering results. To address these issues, this paper proposes a new graph clustering methods (namely Low-rank Sparse Subspace clustering (LSS)) to simultaneously learn the similarity matrix and conduct the clustering from the low-dimensional feature space of the original data. Specifically, the proposed LSS integrates the learning of similarity matrix of the original feature space, the learning of similarity matrix of the low-dimensional …

Conditional Roc Curves For A Paired Case-Control Design, Yalda Zarnegarnia

Open Access Dissertations

Many areas of research involve the analysis of correlated biomarker data. Correlated biomarker data arise from study designs including subjects that contain shared genetic or environmental factors. In a familial-matched design, the information about correlation might help to identify family members at increased risk of disease development and may lead to initiating treatment to slow or stop disease progression. Receiver operating characteristic (ROC) curves have been widely used in medical research to illustrate the performance of a biomarker in correctly distinguishing between diseased and non-diseased groups. Approaches appropriate to a familial-matched case-control design should accommodate inherent correlation in correctly estimating …

Analysis Of Sprint Start Transition Phases And Their Associations With Performance, Steffi L. Colyer, Philip Graham-Smith, Aki I.T. Salo

ISBS Proceedings Archive

The sprint start consists of three transitions defined by the instants the hands, rear leg and front leg leave the ground, which delimit three phases. Ground reaction forces produced by 57 sprinters during the block phase were analysed to investigate the performance (average horizontal external power) implications of transition timing and the force production and centre of mass (CM) displacements between them. Better sprint starters exhibited higher horizontal (r = 0.47 for phase two), but lower vertical (r = -0.40), CM displacement across shorter time periods. Additionally, more horizontally-orientated force vectors to reduce CM projection angle at each …

Taking Multiple Regression Analysis To Task: A Review Of Mindware: Tools For Smart Thinking, By Richard Nisbett (2015), Jason Makansi

Numeracy

Richard Nisbett. 2015. Mindware: Tools for Smart Thinking.(New York, NY: Farrar, Strauss, and Giroux). 336 pp. ISBN: 9780374536244

Nisbett, a psychologist, may not achieve his stated goal of teaching readers to “effortlessly” extend their common sense when it comes to quantitative analysis applied to everyday issues, but his critique of multiple regression analysis (MRA) in the middle chapters of Mindware is worth attention from, and contemplation by, the QL/QR and Numeracy community. While in at least one other source, Nisbett’s critique has been called a “crusade” against MRA, what he really advocates is that it not be used as …

To do so, Nisbett draws from statistics, correlation, experiments, differences in Western and Eastern thought, and, especially, social influence.

The Relationship Of Christian Education To Adolescent Students' Biblical Worldview, Jason G. Nave

Doctoral Dissertations and Projects

Our worldview affects all things in our lives – even our education. Every education has a founding premise or bias which either espouses a biblical worldview or does not. In addition to the factual content, it is typically delivered or taught by someone with a particular premise or bias. Perspectives vary from person to person, and therefore, so can what they believe to be true. The need for true knowledge to be imparted in an absolutely true context is necessary. Thus, there is the need for a biblical worldview to be established. This study is aimed at assessing the relationship, …

Accelerating 3-D Gpu-Based Motion Tracking For Ultrasound Strain Elastography Using Sum-Tables: Analysis And Initial Results., Bo Peng, Shasha Luo, Zhengqiu Xu, Jingfeng Jiang

Michigan Tech Publications

Now, with the availability of 3-D ultrasound data, a lot of research efforts are being devoted to developing 3-D ultrasound strain elastography (USE) systems. Because 3-D motion tracking, a core component in any 3-D USE system, is computationally intensive, a lot of efforts are under way to accelerate 3-D motion tracking. In the literature, the concept of Sum-Table has been used in a serial computing environment to reduce the burden of computing signal correlation, which is the single most computationally intensive component in 3-D motion tracking. In this study, parallel programming using graphics processing units (GPU) is used in conjunction …

Understanding Volatility: An Analysis Of The Stock Market Return-Variance Correlation, Richard Traub

Honors Scholar Theses

This paper attempts to explain the negative correlation between stock market returns in the United States (measured by the risk premium of the S&P 500 Index) and the respective volatility of these returns. The academic research regarding two primary schools of thought on this issue, the volatility feedback effect and the leverage effect, is furthered as potential explanations for this phenomenon. A tertiary explanation relating to investor behavior is also explored as a viable cause. In order to empirically study this relationship, I examine the risk premium quintiles and the corresponding CBOE Volatility Index levels for the time-series dating from …

Design Of Random And Stationary Sources And Media For Structuring Light On Propagation And Scattering, Jia Li

Open Access Dissertations

The dissertation incorporates a series of investigations relating to the design of coherence states for stationary, random sources, and correlation functions of spatially random, stationary media, for modulation of far fields radiated or scattered from them to the far zone, and, hence, for structuring of any observable statistical properties. In particular, we reveal how the coherence states of sources affect their far-zone radiated properties, including the spectral density, the scintillation index, and the intensity correlation function. Furthermore, we also present results that address how the spatial structuring of the refractive index correlation function of a three-dimensional (3D) medium influences the …

Robustly Optimal Reserve Price, Wei He, Jiangtao Li

Research Collection School Of Economics

We study a robust version of the single-unit auction problem. The auctioneer has confidence in her estimate of the marginal distribution of a generic bidder's valuation, but does not have reliable information about the joint distribution. In this setting, we analyze the performance of second-price auctions with reserve prices in terms of revenue guarantee, that is, the greatest lower bound of revenue across all joint distributions that are consistent with the marginals. For any finite number of bidders, we solve for the robustly optimal reserve price that generates the highest revenue guarantee. Our analysis has interesting implications in large markets. …

Agreement Among Six Methods Of Predicting The Anaerobic Lactate Threshold In Elite Cross-Country Skiers, Sean L. Carter, Ian Newhouse

International Journal of Exercise Science

International Journal of Exercise Science 12(2): 155-172, 2019. The anaerobic lactate threshold (LTan) is used to prescribe training intensity and measure endurance capacity. The LTan identifies a critical point where small increases in workload result in large increases in blood lactate concentration. LTan is usually predicted through visual inspection of a blood lactate (bLa) vs workload plot. Numerous other methods for predicting LTan exist, and the literature lacks a consensus regarding validity of prediction methods. The purpose of this study was to assess the agreement among visual inspection (VI), maximum distance (Dmax) and modified maximum distance (Dmod) from the lactate …

Measuring Regulatory And Noncompliance Prevalence Among Maryland Commercial Blue Crab Fishers, Jacquelyn Lee Rachor Hornsby

Walden Dissertations and Doctoral Studies

Few empirical studies exist that compare regulation (R) and fishing crime (VL). The lack of information about R and VL effects stakeholder decision-making. Crime weakens conservation efforts and creates false baseline data. This furthers R and the cycle repeats. The purpose of this correlational study was to determine the statistical association between the number and type of annual commercial blue crab R and VL of the same. The Pearson's R correlation was used to analyze the data because it demonstrated the strength of each relationship. This quantitative study was grounded in enforcement theory. The data was public record and consisted …

Accurate And Compact Stochastic Computations By Exploiting Correlation, Hamdan Abdellatef, Mohamed Khalil Hani, Nasir Shaikh-Husin

Turkish Journal of Electrical Engineering and Computer Sciences

Recent studies have shown, contrary to what was previously believed, that by exploiting correlation in stochastic computing (SC) designs, more accurate SC circuits with low area cost can be realized. However, if these basic SC circuits or blocks are cascaded in series to form a large complex system, correlation between stochastic numbers (SNs) from one block to the next would be lost; thus, inaccuracies are introduced. In this study, we propose correlating circuits to be used in building complex correlated SC systems. One of the circuits is the correlator that restores lost correlations between two SNs due to previous processing. …

Removing Vehicle Speed From Apparent Wind Velocity, Austin M. Weiss

Theses and Dissertations--Biosystems and Agricultural Engineering

Variable-rate technologies for sprayer applications stand to increase efficacy by ensuring the right amount of chemical is applied at the right location. However, external environmental factors such as droplet drift caused by variable ambient condition, are not yet integrated into modern sprayer systems. Real-time wind velocity measurements can be used to control droplet spectra for reducing spray drift by actuating a variable-orifice nozzle. This work aimed to develop data processing methods needed to filter noise and remove vehicle speed from wind velocity measurements collected with an ultrasonic anemometer aboard a moving platform. Using a global navigation satellite system (GNSS), vehicle …
