Application Of Double Sampling To Combine Measured And Imputed Genotype Data In Genetic Association Studies, Qilong Yuan

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Genotype imputation provides an essential technique for genome-wide association studies (GWAS) with hundreds of thousands of SNPs. Understanding the connection between imputation inconsistencies and the power to detect association at imputed markers or the disease genes close to them is important for the optimal design of imputation-based GWAS since genotype misclassification can significantly decrease statistical power to detect association. Double sampling of genotypes is a statistical procedure in which a portion of subjects receive a second and more precise genotyping. This paper applies the likelihood ratio test allowing for errors (LRT-AE), which incorporates double sample information for genotypes on a …

Overall Properties Of Piezoelectric Particulate Composites: Homogenization Estimates And Finite-Element Simulations, Sumantu Iyer

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

This work presents a) an analytic model based on homogenizationestimates to obtain explicit solutions for the effective properties ofparticulate piezoelectric composites and b) a three-dimensionalfinite-element model to compare finite-element results and study thebehaviour of porous piezoelectric composites with four differentgeometric configurations. The analytic model extends the Suquet[29] estimates method to the piezoelectric domain where acomplete set of electromechanical constants are obtained for threepiezoelectric ceramics belonging to different symmetry classes.Specific results are generated for the cases of a square arrangementof cylindrical pores, where the alignment of the pores is in thedirection of poling of the matrix phase and a cubic arrangement …

Analysis Of Single And Dual Under-Expanded, Rarefied Jets, Wenhai Li

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

A numerical study, using the Direct Simulation Monte Carlo (DSMC) approach, of the interaction effects between two identical sonic under-expanded nitrogen jets under rarefied conditions is reported. In this paper, the effects of the jet stagnation Knudsen number (Kn_s), the ratio of the stagnation-to-background pressure (P_s/P_b), and the distance between the jet orifices (L/D) were investigated for a range of these parameters. The background pressure has a very significant effect on the physics of flow, and the interactions between the two jets affect the location of the Mach disks for both the primary and …

Finding Highly Probable(Robust) Paths In The Presence Of Uncertain Weather, Ashish Lohia

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Uncertain weather conditions is one of the biggest challenges faced by air traffic route management. The US airspace is constructed of virtual freeways and all flights have predetermined routes on which to fly, which have originated over years of work and experience. These flight routes are sometimes marred by bad weather conditions which force the pilots to take on alternative routes. It is not very difficult to come up which these alternates if the conditions are known in advance but the real challenge comes when they come up unexpectedly enroute.Stochastic weather conditions such as turbulance and icing are very difficult …

Contributions Of The Inhibitor Of Kappa B Kinases (Ikks) In Macrophages And Neutrophils After Francisella Tularensis Live Vaccine Strain (Lvs) Infection., Sylvia Samaniego

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The immune system is a complex network of cells regulated by a number of signaling pathways to drive specific host defenses against invading pathogens. The NF-&kappaB (nuclear factor of the kappa light chain enhancer in B cells) family of inducible transcription factors is a critical regulator of many innate and adaptive immune responses. NF-&kappaB activation by several receptors converges upon two upstream kinases, IKK&alpha and IKK&beta, that regulate gene induction. Many studies report that IKK&beta is the critical kinase involved in NF--&kappaB activation, although at a transcriptional level, both kinases are needed to obtain the full spectrum of gene induction. …

Life After Beanbag Genetics: Theoretical And Empirical Studies On Epistasis And Penetrance, Joseph Lachance

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Population genetics reduces the description of a population to a set of genotype frequencies. Because of this, it has been called"beanbag genetics.". However, greater complexity and biological realism can be incorporated into this framework. Two examples of this include interactions between different genes (epistasis) and individuals with the same genotype that have different phenotypes (incomplete penetrance). During the course of my Ph.D. work, both of these topics were investigated using theoretical population genetics and Drosophila genetics. One unifying theme was that genes do not exist in isolation: they occur within genetic and environmental contexts. In turn, these contexts were found …

Statistical Models For Snp Detection, Shengnan Cai

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Variations in DNA sequences of humans have a strong association with many diseases. Single Nucleotide Polymorphism (SNP) is the most common type of DNA variations. Our research is to detect SNPs from the data generated by Polymerase Chain Reaction (PCR) and next generation sequencing methods. In the first part of the study, we had a relatively small data set with fewer known SNPs as the training data. We developed a classification model based on the cross validation method. From the first part of the research, we gained knowledge of the properties of the data. In the next phase, we obtained …

Rational Curves In Low Degree Hypersurfaces Of Grassmannian Varieties, Robert Adam Findley

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

We consider two properties of the Kontsevich moduli spaces of genus-0 stable maps to a variety X. The first, irreducibility, implies that certain genus-0 Gromov-Witten invariants are enumerative. The second, existence of very twisting families, implies the existence of sections for a two parameter family with vanishing elementary obstruction. Both of these properties are known to hold for homogeneous varieties, as well as low degree hypersurfaces in projective space.Motivated by these results for projective space, we prove that the Kontsevich moduli spaces are irreducible when X is a low degree hypersurface in a Grassmannian variety. We conjecture a sharp inequality …

Seasonal Aggregations Of The Florida Manatee (Trichechus Manatus Latirostris) In The Port Everglades And Intracoastal Regions Of Fort Lauderdale, Florida., Jaime M. Goldman

HCNSO Student Theses and Dissertations

The Florida manatee (Trichechus manatus latirostris), a subspecies of the West Indian manatee, is one of the most endangered marine mammals in United States waters. The Florida manatee is the only manatee that ranges into subtropical and temperate regions. During the winter months manatees adopt a “refuging strategy” where they aggregate at warm-water sources immediately following decreases in the ambient water temperature to below 20° C (68° F) in order to avoid cold stress syndrome (CSS). During the winter manatees aggregate in warm water refuges, including natural warm water springs and the effluent discharges of power plants.

Modeling The Random Component Of Manufacturing Yield Of Integrated Circuits., David L. Farnsworth, Michael E. Long

Articles

A model is created for the number of integrated circuits that are good from each wafer on which they are fabricated. The goal is to separate the random or common cause loss from the systematic or special loss. The random loss from this type of process is modeled so that false alarms indicating systematic loss are less likely to occur and so that the structure of the systematic loss can be determined.

Generalized Twisted Quantum Doubles And The Mckay Correspondence, Christopher D. Goff, Geoffrey Mason

College of the Pacific Faculty Articles

We consider a class of quasiHopf algebras which we call generalized twisted quantum doubles. They are abelian extensions H=C[G¯]∗⋈C[G] (G is a finite group, G¯ a homomorphic image, and * denotes the dual algebra), possibly twisted by a 3-cocycle, and are a natural generalization of the twisted quantum double construction of Dijkgraaf, Pasquier and Roche. We show that if G is a subgroup of SU₂(C) then H exhibits an orbifold McKay Correspondence: certain fusion rules of H define a graph with connected components indexed by conjugacy classes of G¯, each connected component being an extended affine Diagram of …

Features Extraction Using Random Matrix Theory., Viktoria Borisovna Rojkova

Electronic Theses and Dissertations

Representing the complex data in a concise and accurate way is a special stage in data mining methodology. Redundant and noisy data affects generalization power of any classification algorithm, undermines the results of any clustering algorithm and finally encumbers the monitoring of large dynamic systems. This work provides several efficient approaches to all aforementioned sides of the analysis. We established, that notable difference can be made, if the results from the theory of ensembles of random matrices are employed. Particularly important result of our study is a discovered family of methods based on projecting the data set on different subsets …

Data Mining And Analysis Of Lung Cancer Data., Guoxin Tang

Electronic Theses and Dissertations

Lung cancer is the leading cause of cancer death in the United States and the world, with more than 1.3 million deaths worldwide per year. However, because of a lack of effective tools to diagnose Lung Cancer, more than half of all cases are diagnosed at an advanced stage, when surgical resection is unlikely to be feasible. The main purpose of this study is to examine the relationship between patient outcomes and conditions of the patients undergoing different treatments for lung cancer and to develop models to predict the mortality of lung cancer. This study will identify the demographic, finance, …

Adriamycin Nephrotoxicity Is Reduced By Metallothionein Over-Expression And Kidney Gene Expression Is Modified By Diabetes In The Ove26 Diabetic Model., Lu Yang

Electronic Theses and Dissertations

This thesis is divided into two parts below. Part I Adriamycin (ADR) can produce nephrotoxicity in rodents. The underlying mechanism may relate to ADR induced oxidative stress. In this study, we used transgenic mice (NMT3), which over-expressed the antioxidant protein metallothionein (MT) in podocytes, to study MT's protective potential on ADR nephrotoxicity. Urine and kidney samples were collected from control and transgenic mice at multiple time points after ADR injection, whose results showed that MT transgene alleviated ADR damage by reducing albuminuria, decreasing podocyte loss and protecting podocyte ultra-structure. Part II OVE26 mice are a good model of severe diabetic …

The Four-Year Experience Of First-Generation Students At A Small Independent University : Engagement, Student Learning, And Satisfaction., David M. Mahan

Electronic Theses and Dissertations

This dissertation explored the four-year college experience of first-generation and continuing-generation students at a small private institution. Using Astin's I-E-O model (1970), the following variables in the student experience were considered: precollege student characteristics (input); engagement in academic experiences, cocurricular activities, campus relationships (environment); and satisfaction, learning (outcome). The sample consisted of seniors participating in the National Survey of Student Engagement (NSSE) and/or a direct measure of general education learning, the ETS Measure of Academic Proficiency and Progress. Results of the analysis of learning indicated no difference in first-generation and continuing-generation students' measures (n = 342). One exception was found …

English Language Learners In Focus : Predictors Of English Proficiency And Academic Achievement., Yuliya Ardasheva

Electronic Theses and Dissertations

Academic achievement of English language learners (ELLs), the fastest growing population in the U.S. schools, deserves greater attention. This non-experimental study investigated the unique contributions-above and beyond other individual difference and school characteristics-of language learning strategies (LLS) to student academic outcomes in a second language (L2). The sample comprised 1,057 ELLs (651 elementary, 275 middle, and 131 high school) attending 38 schools in one urban school district. Descriptive analysis results indicated that ELLs used a large array ofLLS; yet, except for metacognitive strategies, most LLS were reportedly used only at a medium level of frequency. The results also indicated a …

A Generic Framework For Context-Dependent Fusion With Application To Landmine Detection., Ahmed Chamseddine Ben Abdallah

Electronic Theses and Dissertations

For complex detection and classification problems, involving data with large intra-class variations and noisy inputs, no single source of information can provide a satisfactory solution. As a result, combination of multiple classifiers is playing an increasing role in solving these complex pattern recognition problems, and has proven to be a viable alternative to using a single classifier. Over the past few years, a variety of schemes have been proposed for combining multiple classifiers. Most of these were global as they assign a degree of worthiness to each classifier, that is averaged over the entire training data. This may not be …

Development Of A Simulation And Evaluation Environment For A Traffic Flow Analysis System., Peter Bernhardt 1973-

Electronic Theses and Dissertations

A system for analysis of the traffic flow on public streets and highways through the use of Floating Car Data (FCD) relies completely on the number of simultaneously contributing vehicles, a fact that is no barrier for the phases of conception and development but poses a serious issue for the testing of such a system. Especially for smaller institutions or companies where the ability and resources to field the required number of participants is not given which in turn leads to the need for computational support to substitute the use of real vehicles by simulation. This thesis focuses on the …

Specifically, a study on the teaching methods for the resident physicians was examined to determine if there were different approaches that could be implemented to improve a patient's time in the emergency department. Findings showed that the teaching …

The Gorilla And The Cuttlefish., Nick Karl 1982-

Electronic Theses and Dissertations

The new work I have developed while pursuing my Masters in Art at the University of Louisville is strongly based on the narrative. I have always used the imagery in my work as social commentary. The stories and images I develop are to be viewed as a window on the world through my eyes, but for the first time I have focused on one clear concept. In this case, questioning how we developed from a group of hunter-gatherers scouring the land for survival, to modern consumers, destroying the world around us. In order to facilitate this narrative, I wrote a …
