The Evolution Of Cercopithecoid Locomotion: A Morphometric, Phylogenetic, And Character Mapping Approach, Ashley Daria Gosselin-Ildari Dec 2013

The Evolution Of Cercopithecoid Locomotion: A Morphometric, Phylogenetic, And Character Mapping Approach, Ashley Daria Gosselin-Ildari

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

Cercopithecoidea is the superfamily within the order Primates representing Old World Monkeys. Cercopithecoids are relatively rare in the fossil record prior to the middle Miocene. However, since the PlioPleistocene, cercopithecoids have undergone a diversification making them one of most ecological diverse groups of primates today. Although cercopithecoids are ecologically and behaviorally diverse, their locomotor behavior is not considered specialized and their postcrania reflect a generalized quadrupedal locomotor repertoire. Many cercopithecoids today are considered " semi-terrestrial" meaning that they are efficient on the ground and in the trees. However, the colobines are almost exclusively arboreal and committed terrestriality is thought to …

Structural Study Of Ino80 Chromatin Remodeling Protein Complex By Cryo-Em, Won Kyun Koh

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

The human genome, comprised of ~three billion base pairs, is over six feet long when fully extended. Multiple chromatin modifying enzymes are required either to condense the DNA to fit into each nucleus that are ~ 1um in size, or to partially unravel the chromatin for readout of the genomic information. The ATP-dependent chromatin remodeler INO80 plays important roles in regulating the spacing of nucleosomes along the DNA. However, mechanism by which INO80 slides the nucleosome is still unclear. Structural studies of other chromatin remodelers have been shown to be a powerful approach to understand how these enzymes interact with …

Applications Of Multichannel Brain Array Coils In Functional Neuroimaging, Sheeba Rani Arnold Anteraper

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

Deciphering signal from noise is a pre-requisite for making any scientific observation. Regardless of the imaging modality, any successful attempt in improving the Signal-to-Noise Ratio (SNR) brings about a wave of applications. The use of multichannel array coils in functional and structural magnetic resonance imaging (MRI) provides increased SNR, higher sensitivity, and parallel imaging capabilities. However, their benefits remain to be systematically explored in the context of resting-state functional connectivity MRI (fcMRI). In this work, signal detectability within and between commercially available multichannel brain coils, a 32-Channel (32Ch), and a 12-Channel (12Ch) were compared at 3 Tesla, in a high-resolution …

Analysis Of The Interaction Of H-Nox With Dgc Using In Vivo Methods And Analytical Ultracentrifugation, Patryk Zielinski

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

Biofilms are a naturally occurring phenomenon and are known to be a significant problem in various fields including both the industrial and health environments. Bacterial biofilms are defined as the attachment and aggregation of a community of bacteria to solid surfaces. This behavior can lead to infections via medical transplants and compromise the functionality and durability of industrial equipment. Two proteins, Heme-Nitric oxide/Oxygen (H-NOX) and di-guanylate cyclase (DGC), are known to play an important role in the regulation of biofilm formation in bacteria. These two proteins down regulate the concentration of c-di-GMP, a second messenger molecule, in a cell. Since …


Imaging Coherent Electronic Motion In Atoms By Ultrafast Electron Diffraction, Hua-Chieh Shao, Anthony F. Starace Dec 2013

Imaging Coherent Electronic Motion In Atoms By Ultrafast Electron Diffraction, Hua-Chieh Shao, Anthony F. Starace

Anthony F. Starace Publications

Ultrafast electron diffraction from time-varying coherent electronic states of the H atom is analyzed theoretically. This theoretical analysis identifies the conditions necessary to obtain time-resolved measurements. Electron diffraction from coherent electronic states exhibiting breathing and wiggling modes of electronic motion are simulated numerically in order to demonstrate the capability of attosecond electron pulses to image electron dynamics. The scattering patterns and their temporal behaviors are shown to differentiate the two kinds of target electronic motion. Moreover, our simulations show that inelastic processes contribute significantly to the diffraction patterns. Thus, although the diffraction patterns clearly distinguish different modes of target electronic …


Patrick Chamoiseau Et La Poétique Du «Nomadismecirculaire», Samia Kassab-Charfi Dec 2013

Patrick Chamoiseau Et La Poétique Du «Nomadismecirculaire», Samia Kassab-Charfi

Présence Francophone: Revue internationale de langue et de littérature

By advocating a fluid and metamorphic type of creolity, Patrick Chamoiseau has managed to distance himself from any claim to a particular identity. His latest poetics refute more than ever the elegy of origin and the celebration of race. In Glissant’s footsteps, he experiments with the notion of “circular nomadism”, which becomes a major rite of initiation for many of his characters. That same notion, at the heart of the amorous gravitation by which he unveils the treasures of his sentimenthèque, finally leads to an ethic of transformation, a kind of “eco-philosophy” where every exodus becomes an exordium, a new …

La Condition Postmétisse, Célestin Monga Dec 2013

La Condition Postmétisse, Célestin Monga

Présence Francophone: Revue internationale de langue et de littérature

Patrick Chamoiseau’s thought has evolved considerably over the past twenty-five years. Whether it inscribes itself in the registers of utopia or counter-utopia, it has moved away from the linguistics issues of creoleness to acquire a humanistic thickness. It now advocates the advent of a global identity that could be viewed as “post-mestizo”. This essay analyzes its invocation of the Tout-Monde and its faith in a universal poetics of relation. It also assesses the empirical basis for his views in a world where nihilism appears to be the only credible virtue.


The Effects Of Standards-Based Grading On Student Performance In Algebra 2, Rachel Beth Rosales Dec 2013

The Effects Of Standards-Based Grading On Student Performance In Algebra 2, Rachel Beth Rosales

Dissertations

The use of standards-based grading in American public schools is increasing, offering students, parents, and teachers a new way of measuring and communicating about student achievement and performance. Parents indicate an appreciation for this method of grading, and students at the elementary grades (K-6) have improved standardized test scores in reading and math as a result of its implementation. This study seeks to determine whether standards-based grading has the same effect on students at the high school level (grades 9-12) by comparing end-of-course test scores and posttest scores of Algebra 2 students enrolled in a standards-based graded classroom with to …


Forensic Investigation Of Mysql Database Management System, Andrew C. Lawrence Dec 2013

Forensic Investigation Of Mysql Database Management System, Andrew C. Lawrence

Computer Science and Computer Engineering Undergraduate Honors Theses

For various reasons, circumstances might arise in which an investigator, enlisting the help of a system administrator, needs access to an instance of MySQL that is password protected by an individual system user. If this password is unknown and the user is uncooperative or unavailable, alternative means must be utilized to gain access to the data stored within the program. Two main approaches will be explored, each with its pros and cons. In one case, the password can be bypassed entirely, granting the investigator unfettered access to the program data. The second method allows a narrower look at only some …

The Glycine And Proline Reductase Systems: An Evolutionary Perspective And Presence In Enterobacteriaceae, Joshua Witt Dec 2013

The Glycine And Proline Reductase Systems: An Evolutionary Perspective And Presence In Enterobacteriaceae, Joshua Witt

HIM 1990-2015

The Glycine and Proline Reduction systems are two of the best characterized selenoenzymes in bacteria and have been found to occur in a wide variety of clostridia [1-5]. These enzymes are utilized to reduce glycine or D-proline to obtain energy via substrate level phosporylation or membrane gradients, respectively [6, 7]. This includes the pathogens C. difficile and C. botulinum [5, 8]. Strains of C. difficile are activate toxigenic pathways whenever either of these pathways is active within the cell [5, 8]. Though evolutionary studies have been conducted on ammonia producing bacteria [9] none has been done to directly characterize these …

Feasible Algorithms For Lattice And Directed Subspaces, Jennifer (Hamlyn) Del Valle, Vladik Kreinovich, Piotr Wojciechowski Dec 2013

Feasible Algorithms For Lattice And Directed Subspaces, Jennifer (Hamlyn) Del Valle, Vladik Kreinovich, Piotr Wojciechowski

Departmental Technical Reports (CS)

In some practical situations (e.g., in econometrics), it is important to check whether a given linear subspace of a space Rm with component-wise order is a lattice -- and if it is not, whether it is at least a directed ordered space. Because of the practical importance, it is desirable to have feasible algorithms for solving these problems -- which in Computer Science is usually interpreted as algorithms whose computation time does not exceed a polynomial of the length of the input. No such algorithms were previously known. In this paper, we present feasible algorithms for solving both problems.

Single Nucleotide Polymorphisms Linked To Essential Hypertension In Kasigau, Kenya, Julia Carol Freeman Dec 2013

Single Nucleotide Polymorphisms Linked To Essential Hypertension In Kasigau, Kenya, Julia Carol Freeman

Masters Theses & Specialist Projects

Hypertension, or high blood pressure (BP), is an ever-growing epidemic in the developing world. Understanding the genetics behind essential hypertension (EH), or hypertension with no known cause, is especially important. In this study, three single nucleotide polymorphisms (SNPs) known to be linked to an increase in susceptibility to EH were quantified from a cohort of Kenyans living in the Kasigau region. The SNPs are located in three genes that are part of the renin angiotensin system, the primary regulatory pathway in humans controlling BP. They include: AGT (rs699), AGTR1 (rs5186), and HSD11β2 (rs5479). Overall, by using a fluorescent-based RT-PCR technique, …
