Manipulation Of Dna At Polymer Surfaces: Electric-Field Controlled Adsorption, Patterned Cutting And Stretching, Ke Zhu Dec 2016

Manipulation Of Dna At Polymer Surfaces: Electric-Field Controlled Adsorption, Patterned Cutting And Stretching, Ke Zhu

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

Recent developments in next generation DNA sequencing and optical restriction mapping involve manipulation of DNA molecules on surfaces. Here we propose a novel method that can control the adsorbed DNA density on polymer surfaces by applying an electric field. The efficiency of deposition was optimized with respect to DNA concentration in solution, electric field type and electric field strength. Enhancement of adsorption density of greater than twenty-fold was found. In addition, DNA molecules are fragmented on a polymer surface by soft lithography. Several experimental conditions have been tested to optimize the polydimethylsiloxane (PDMS) stamp fabrication and DNA cutting method. Fragmented …

Sovereign Invulnerability: Sexual Politics And The Ontology Of Rape, Jane Clare Jones Dec 2016

Sovereign Invulnerability: Sexual Politics And The Ontology Of Rape, Jane Clare Jones

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

As Rebecca Whisnant has noted, notions of “national…and…bodily (especially sexual) sovereignty are routinely merged in rhetoric and metaphor.†(2008:155) Departing from this observation, this project explores the ‘existential infrastructure’ of the ‘logic of sovereign integrity’ in which personhood is thought as analogous to jurisdiction over a bounded territorial enclosure. It traces the philosophical history of this logic, and unfolds the post-Heideggerian French critique of sovereignty as an analysis of how sovereign imperatives are animated by a drive to deny the vulnerabilities of constitutive ontological relation, and are thus implicated in violent cycles of disavowal and appropriation. It then applies this …

The Role Of Protein Kinase C In Mammalian Target Of Rapamycin Signaling And Its Therapeutic Implications In Non-Small Cell Lung Cancer, Mengling Liu Dec 2016

The Role Of Protein Kinase C In Mammalian Target Of Rapamycin Signaling And Its Therapeutic Implications In Non-Small Cell Lung Cancer, Mengling Liu

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

The mammalian target of rapamycin (mTOR) signaling pathway, which integrates extracellular and intracellular signals, plays a key role in cell metabolism, growth and survival; therefore, the proteins in the signaling pathway must be tightly regulated in order to maintain cellular homeostasis. Conversely, dysregulation of key components of mTOR signaling pathway leads to increased cellular growth and proliferation, which is implicated in many human cancers. Protein kinase C (PKC) is a family of serine/ threonine kinases that regulate many cellular processes including proliferation and cell survival. It has been shown to regulate mTOR signaling in some human cancers. However, the mechanism …

Task Scheduling In Modern Data Center: Task Placement And Resource Allocation, Li Shi Dec 2016

Task Scheduling In Modern Data Center: Task Placement And Resource Allocation, Li Shi

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

In modern data centers, the wide use of virtualization techniques has enabled dynamic resource allocation in the form of virtual machines and virtual networks. With such an ability, scheduling tasks, including both computing tasks and data transfer tasks, comprises (a) placing tasks on servers or network paths and (b) allocating a certain amount of resources to each task. In such a context, minimizing the completion time of the tasks, as a critical goal on many task processing platforms, requires joint consideration of both task placement and resource allocation. While many approaches have been proposed in the area of scheduling tasks …

Light-Induced Self-Assembly And Diffusion Of Nanoclusters, Wenxuan Lian Dec 2016

Light-Induced Self-Assembly And Diffusion Of Nanoclusters, Wenxuan Lian

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

Novel methods to build multiple types of three-dimensional structures from various nanoscale components are the most exciting and challenging questions in nano-science. The properties of the assembled structures can be potentially and designed, but the development of such approaches is challenging. In order to realize such rational assembly, a tunable interaction medium is often introduced into the system. Soft matter, such as polymers, surfactants and biomolecules are used to modify the surfaces of the nanoscale building blocks. Deoxyribonucleic acid (DNA) strands are known as polynucleotides since they are composed of simpler units called nucleotides. There are unique base pairing rules …

Molecular Strong Field Ionization Viewed With Photoelectron Velocity Map Imaging, Peter Sandor Dec 2016

Molecular Strong Field Ionization Viewed With Photoelectron Velocity Map Imaging, Peter Sandor

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

In this thesis, work is presented on molecular strong-field ionization, during which an electron is removed from polyatomic molecules in the presence of strong laser fields. This is a process which is the basis of a number of experimental techniques to uncover electronic dynamics in atoms and molecules on the femtosecond and attosecond timescale. ’Strong’ refers to an electric field strength which leads to a response from the system which can not be modeled perturbatively. These fields can be easily produced in the focus of femtosecond laser radiation, as is done in this work. With the use of velocity map …

Physical Polymerization Mechanisms In The Chemistry-To-Biology Transition, Elizaveta Guseva Dec 2016

Physical Polymerization Mechanisms In The Chemistry-To-Biology Transition, Elizaveta Guseva

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

Studying complex systems and emergent phenomena is very popular today. The reason is that we desperately need more knowledge about many complex systems such as cells, organisms, society and emergent phenomena on the internet. Applying physical and quantitative methods to such systems resulted in many discoveries, yet a lot of knowledge is missing. In particular, we don’t fully understand living systems including their emergence. What are the minimal requirements for life? How to make a chemical system capable of inheritance and open ended evolution? If a system is capable of Darwinian evolution, is it necessarily a living system? Modern life …

Fabrication Of A Novel Biosensor For Macromolecules Detection Through Molecular Imprinting Technique, Yingjie Yu Dec 2016

Fabrication Of A Novel Biosensor For Macromolecules Detection Through Molecular Imprinting Technique, Yingjie Yu

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

There is an increasing need for precise molecular detection as a diagnostic tool for early identification of diseases, pathogens, and abnormal protein levels in the body. Typical chemical analytical methods are generally costly, unstable, and time-consuming. Molecular imprinting (MI) technique，based on the “lock and key model†, could be a simple method to overcome those shortcomings. In this study, a self-assembled monolayer (SAM) was employed as a platform to fabricate MI biosensor for detection of macromolecules. I demonstrated that, when the monolayer was formed on a rough surface, this method was in fact templating molecules in three dimensions, and hence …

A Spatio-Temporal Model Of Hunter-Gatherer Foraging Ecology Across The North American Great Plains Throughout The Paleoindian Period: Development Of Biological Theory And Statistical Methods To Link Human Evolutionary Biology, Ecology, And The Archaeological Record, Erik Roque Otárola-Castillo

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

Hunter-gatherers spread to nearly every corner of the planet in large part due to their flexible ability to forage for high-quality foods in diverse environments. The study of human foraging behavior is therefore crucial to understanding the proximate and ultimate factors that have shaped human evolutionary history. Although not necessarily in an evolutionary context, the foraging behavior of Paleoindian hunter-gatherers in North America has been studied for over a century. Researchers have paid particular attention to Paleoindian foragers’ hunting of big game across the grasslands of the Great Plains, shedding light on “what†prey Paleoindians foraged, “where†foraging occurred on …

Pathogenic And Non-Pathogenic Strains Of Vibrio Parahaemolyticus In Long Island Sound: Biotic And Abiotic Factors Promoting Abundance, Jake Thickman

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

Food safety is a major concern in the shellfish industry, as severe illness can result from consuming shellfish that have accumulated waterborne pathogens. Shellfish harvesting areas are typically monitored for indicator bacteria such as fecal coliforms that serve as proxies for enteric pathogens introduced from surrounding waterways, but these indicators have shown little relation to some naturally occurring pathogenic bacteria such as Vibrio parahaemolyticus (Vp). To examine the dynamics and ecology of pathogenic and non-pathogenic strains of Vp and address the relevance of indicator bacteria in predicting Vp concentrations, field surveys and experiments were carried out in western Long Island …

Clustering And Classification Methods For Prediction Of The Risk For Developing Disease, Hyejoo Lee Dec 2016

Clustering And Classification Methods For Prediction Of The Risk For Developing Disease, Hyejoo Lee

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

The purpose of this study is to develop a statistical model to predict the risk for developing disease. In order to enrich our general understanding of schizophrenia disorder, several clustering techniques are used as a preliminary study. Schizophrenia is a heterogeneous decease with great variability in symptoms, cognition, biology and course of illness. Some of this variability may be explained by latent subgroups that differ in etiology and key features. Individuals with paternal age related schizophrenia (PARS) may represent such a subgroup as evidence suggests a distinct symptom profile. Using K-means and hierarchical clustering on a large sample of schizophrenia …

Response To Monetary And Social Feedback During Development: Associations With Depressive Symptomatology And Risk, Jennifer Nicole Bress Dec 2016

Response To Monetary And Social Feedback During Development: Associations With Depressive Symptomatology And Risk, Jennifer Nicole Bress

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

Depression represents a major public health concern, with particularly harmful effects in children. Existing interventions show relatively low response rates and high relapse rates, and there has been a recent effort to identify biomarkers of depression that may improve interventions and guide the way for novel treatments. One potential biomarker is the neural response to reward. However, existing studies typically focus on monetary reward, which may be less relevant to children and adolescents than social feedback. The current study focused on the feedback negativity (FN), an event-related potential (ERP) typically elicited by monetary feedback, in the context of a novel, …

Complementarity In The Structure And Dynamics Of Protein-Dna Search And Recognition: A Multiscale Modeling Study, Kevin E. Hauser Dec 2016

Complementarity In The Structure And Dynamics Of Protein-Dna Search And Recognition: A Multiscale Modeling Study, Kevin E. Hauser

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

Transcription factors (TF) interact with DNA to regulate gene expression by specifically binding one or two sequences out of millions of possible sites in a genome. Sequence specific binding (recognition) arises from two mechanisms: amino acid-nucleobase H-bonding (direct readout), and sequence-dependent DNA deformability and structure (indirect readout). These lead to tight, specific binding. TFs can also rapidly search for their target by attaching to any sequence and then sliding along DNA. This decreases the space through which a TF randomly walks to stumble on the target. Tight binding and rapid sliding are optimized because TFs can switch between different DNA-binding …

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

In 2014, an estimated 480,000 people developed MDR-TB and 190,000 people died as a result of it. Approximately 9.7 % of people with MDR-TB are estimated to have XDR-TB. With the increase in the number of MDR-TB and XDR-TB cases, there is a dire need for the development of new anti-TB agents with novel mechanism of action. FtsZ, a crucial bacterial cytokinesis protein is a potential target for the development of new anti-TB agents. Previously a library of 2,5,6- and 2,5,7-trisubstituted benzimidazoles were synthesized and tested for their anti-TB activity. The lead molecules inhibited the assembly of Mycobacterium tuberculosis FtsZ …

Synthesis Of New Generation Taxoid Anticancer Agents And Dendrimer-Based Multifunctional Conjugates For Tumor-Targeting Drug Delivery, Yi Sun

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

Cancer remains the second leading cause of death in the United States. Although tremendous efforts have been made in the area of cancer therapy, there is still no common cure for cancer. Paclitaxel, which is a microtubule stabilizer, is used as an antitumor agent against several cancers such as ovarian, lung, and breast cancer. However, paclitaxel shows poor antitumor activities against drug resistant cell lines, and may cause undesirable side effects. Over the past decades, significant achievements have been made in the development of new generation taxoids that exhibit increased cytotoxicity against resistant cancer cell lines. Additionally work has been …

Development Of Antitubercular Agents Targeting Ftsz And Antinociceptive Agents Targeting Fatty Acid Binding Proteins (Fabp), Simon Tong

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

Tuberculosis, responsible for 1.5 million deaths worldwide in 2014, is treated using first and second line drugs. The repertoire of treatments has remained virtually static for decades, but the prevalence of drug resistance has increased. The rise of MDR- and XDR-TB has rendered current treatments ineffective, and new anti-tubercular agents with unique mechanisms of action are needed to overcome this hurdle. Filamenting temperature-sensitive mutant Z (FtsZ) is an essential bacterial cell division protein and a promising target. Inhibition of FtsZ will disrupt cell division, killing bacterial cells. Libraries of 2,5,6- and 2,5,7-trisubstituted benzimidazoles were previously synthesized and tested against Mtb …

The Macro- And Micro-Anatomy Of Primate Volar Surfaces, Amanda Kathryn Kingston Dec 2016

The Macro- And Micro-Anatomy Of Primate Volar Surfaces, Amanda Kathryn Kingston

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

The soft tissues of the volar surfaces of primate hands and feet are the primary point of interaction between an individual animal and its environment and, as such, are likely to be under strong functional selection. These tissues serve three major functions: 1) force attenuation – the volar fat pads assist in attenuating reaction forces generated during grasping locomotion; 2) friction enhancement – the volar fat pads also act as viscoelastic surfaces that increase the coefficient of friction between the pads and substrate at low body weights; in addition, the ridged volar skin interlocks with and thus increases friction with …

Reduced Snow Cover Alters Root-Microbe Interactions And Decreases Nitrification Rates In A Northern Hardwood Forest, Patrick O. Sorensen, Pamela H. Templer, Lynn M. Christenson, Jorge Durán, Timothy J. Fahey, Melany C. Fisk, Peter M. Groffman, Jennifer L. Morse, Adrien C. Finzi Dec 2016

Reduced Snow Cover Alters Root-Microbe Interactions And Decreases Nitrification Rates In A Northern Hardwood Forest, Patrick O. Sorensen, Pamela H. Templer, Lynn M. Christenson, Jorge Durán, Timothy J. Fahey, Melany C. Fisk, Peter M. Groffman, Jennifer L. Morse, Adrien C. Finzi

Environmental Science and Management Faculty Publications and Presentations

Snow cover is projected to decline during the next century in many ecosystems that currently experience a seasonal snowpack. Because snow insulates soils from frigid winter air temperatures, soils are expected to become colder and experience more winter soil freeze-thaw cycles as snow cover continues to decline. Tree roots are adversely affected by snowpack reduction, but whether loss of snow will affect root-microbe interactions remains largely unknown. The objective of this study was to distinguish and attribute direct (e.g., winter snow-and/ or soil frost-mediated) vs. indirect (e.g., root-mediated) effects of winter climate change on microbial biomass, the potential activity of …

The Irrelevance Of Nanotechnology Patents, Emily Michiko Morris Dec 2016

The Irrelevance Of Nanotechnology Patents, Emily Michiko Morris

Faculty Scholarly Works

Although scientists have for decades now had the ability to manipulate matter at the atomic level, we have yet to see the nanotechnological revolution that these scientists predicted would follow. Despite the years of effort and billions of dollars that have been invested into research and development thus far, nanotechnology has yielded surprisingly few end-user applications. A number of commentators have blamed this lack of progress on the Bayh-Dole Act and other changes to patent law, arguing that, although these laws are supposed to stimulate technological development, they have in fact had the exact opposite effect when it comes to …

Regional Mapping Of Flow And Wall Characteristics Of Intracranial Aneurysms, Juan R. Cebral, Xinjie Duan, Piyusha S. Gade, Bong Jae Chung, Fernando Mut, Khaled Aziz, Anne M. Robertson

Department of Applied Mathematics and Statistics Faculty Scholarship and Creative Works

The evolution of intracranial aneurysms (IAs) is thought to be driven by progressive wall degradation in response to abnormal hemodynamics. Previous studies focused on the relationship between global hemodynamics and wall properties. However, hemodynamics, wall structure and mechanical properties of cerebral aneurysms can be non-uniform across the aneurysm wall. Therefore, the aim of this work is to introduce a methodology for mapping local hemodynamics to local wall structure in resected aneurysm specimens. This methodology combines image-based computational fluid dynamics, tissue resection, micro-CT imaging of resected specimens mounted on 3D-printed aneurysm models, alignment to 3D vascular models, multi-photon microscopy of the …

Most double-stranded RNA (dsRNA) viruses are transcribed and replicated in a specialized icosahedral capsid with a T=1 lattice consisting of 60 asymmetric capsid protein (CP) dimers. These capsids help to organize the viral genome and replicative complex(es). They also act as molecular sieves that isolate the virus genome from host defense mechanisms and allow the passage of nucleotides and viral transcripts. Rosellinia necatrix quadrivirus 1 (RnQV1), the type species of the family Quadriviridae, is a dsRNA fungal virus with a multipartite genome consisting of four monocistronic segments (segments 1 to 4). dsRNA-2 and dsRNA-4 encode two CPs (P2 and …
