Growth Of Errors And Uncertainties In Medium Range Ensemble Forecasts Of U.S. East Coast Cool Season Extratropical Cyclones, Minghua Zheng Dec 2016

Growth Of Errors And Uncertainties In Medium Range Ensemble Forecasts Of U.S. East Coast Cool Season Extratropical Cyclones, Minghua Zheng

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

Cool-season extratropical cyclones near the U.S. East Coast often have significant impacts on the safety, health, environment and economy of this most densely populated region. For example, the “January 2015 blizzard†caused thousands of flights cancellations, travel bans enacted in five states, and two related deaths. Hence it is of vital importance to forecast these high-impact winter storm events as accurately as possible by numerical weather prediction (NWP), including in the medium-range (3-6 days). Ensemble forecasts are appealing to operational forecasters when forecasting such events because they can provide an envelope of likely solutions to serve user communities. However, it …

Palmitoylation Of The Nmda Receptor And Psd95 Utilizing Phosphopantetheinyl Transferases, Victor Chang Dec 2016

Palmitoylation Of The Nmda Receptor And Psd95 Utilizing Phosphopantetheinyl Transferases, Victor Chang

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

Signal transduction relies on the proper localization of proteins to properly transfer signals throughout the cell. The cell membrane serves as a vital interface for the proper localization of proteins. Posttranslational modifications cause proteins to become targeted to membranes. One such modification is palmitoylation, the addition of a palmitic acid to a cysteine of a protein. Within the neuron, a large protein complex called the postsynaptic density receives upstream signals at the synapse. Many signaling proteins within the postsynaptic density are known to require palmitoylation for proper trafficking and function. Two such examples are the N-methyl-D-Aspartate receptor (NMDAR) and Post …

Functional Consequences Of A Putative Mek1 Phosphorylation Site On Rad17 During Meiosis In Saccharomyces Cerevisiae, Madeeha Rahat Dec 2016

Functional Consequences Of A Putative Mek1 Phosphorylation Site On Rad17 During Meiosis In Saccharomyces Cerevisiae, Madeeha Rahat

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

Meiosis is a specialized type of cell division, which produces haploid daughter cells from diploid parental cells. Meiotic recombination is initiated by the introduction of programmed DNA double strand breaks (DSBs), which are catalyzed by an evolutionarily conserved, meiosis-specific endonuclease, Spo11. Meiotic cells monitor the repair of Spo11-induced DSBs via the meiotic recombination checkpoint (MRC), which is activated in response to DSBs made during meiotic prophase. The MRC ensures proper repair of DSBs prior to entry into the first meiotic division. The Mec1 checkpoint kinase is recruited to resected DSBs via the 9-1-1 complex containing Rad17, Mec3 and Ddc1. Mec1 …

Topics In Yeast Sporulation, Patrick Singer Dec 2016

Topics In Yeast Sporulation, Patrick Singer

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

Yeast sporulation is the process by which yeast cells under limiting nutrient conditions are able to alter their nuclear division cycle from mitotic division to meiotic division, resulting in development of up to 4 spores per diploid cell. Spores are a hardy cell type that can survive until nutrient conditions improve. Under particularly severe conditions, sporulating cells only produce 2 spores, in an arrangement known as a non-sister dyad (NSD). NSDs contain the two spores with the youngest spindle pole bodies (SPBs), which are produced in meiosis II. The SPBs are the central nucleating point of prospore membranes. A scaffolding …

Role Of Runt, Even-Skipped, And Odd-Paired In Regulating Enhancer Activity In The Drosophila Embryo, Michael Luis Higgins Dec 2016

Role Of Runt, Even-Skipped, And Odd-Paired In Regulating Enhancer Activity In The Drosophila Embryo, Michael Luis Higgins

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

The Drosophila runt gene is the founding member of the RUNX transcription factor family, a group of conserved genes that have vital roles in multiple developmental pathways throughout the animal kingdom. Runt plays important roles in segmentation, as well as in neurogenesis and sex determination in the Drosophila embryo. As a transcription factor, Runt is both an activator and a repressor of its target genes depending on the context. Sloppy-paired (slp1) is a target of runt’s activity as a pair-rule transcription factor in the segmentation pathway that is both activated and repressed by Runt. Two cis-regulatory enhancers of slp1, a …

Investigating The Roles Of P53 Stability And Its Interactions With Chaperone Proteins During Mitochondrial Permeability Transition, Ivan Lebedev

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

Tissue necrosis as a consequence of ischemia-reperfusion injury and oxidative damage is a leading cause of permanent disability and death worldwide. The complete mechanism by which cells undergo necrosis upon oxidative stress is not understood. In response to an oxidative insult, wildtype p53 has been implicated as a central regulatory component of the mitochondrial permeability transition (mPT), triggering necrosis. This process is associated with cellular stabilization and translocation of p53 into the mitochondrial matrix. I explore the mechanism by which p53 activates the key mPT regulator cyclophilin D (CypD); how the stability of p53 affects its ability to interact with …

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

In excess, adipogenesis and adiposity can compromise the quality of the musculoskeletal system, disrupt progenitor cell populations, and increase susceptibility to diabetes. The extent to which muscle and bone tissue are impaired by obesity-related pathologies is not clear. Additionally, while fat, bone, and muscle are distinct tissue systems, the degree to which bone marrow cells contribute to the fat/muscle phenotype in the pre-obese state is yet to be elucidated. To combat obesity, exercise is a common treatment modality that is anabolic to bone and muscle and catabolic to fat. However, compliance is low, obese patients may be unable to exercise …

Biocompatibility And Bioactivity Of One- And Two-Dimensional Nanoparticle Reinforced Polymeric Scaffolds For Bone Tissue Engineering Applications, Jason Thomas Rashkow Dec 2016

Biocompatibility And Bioactivity Of One- And Two-Dimensional Nanoparticle Reinforced Polymeric Scaffolds For Bone Tissue Engineering Applications, Jason Thomas Rashkow

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

Limitations associated with current bone grafting techniques utilizing autologous or allogeneic bone have led to an increase in bone tissue engineering strategies. The ideal scheme of repairing a bone defect is to employ a material that can act as a scaffold and assist regeneration of native tissue in the area. Although biodegradable polymers fulfill many of the requirements for synthetic bone grafts, a major limitation is poor integrity under load bearing conditions prompting investigation of nanoparticle-reinforced biodegradable polymer nanocomposites. Recently, incorporation of 0.2 wt% of two-dimensional organic nanostructures (graphene nanoribbons (GONRs) and graphene nanoplatelets (GONPs)) and one- and two-dimensional inorganic …

Erythrocyte Aggregation Due To Surface Nanobubble Interactions During The Onset Of Thermal Burn Injury, Harrison Steven Seidner Dec 2016

Erythrocyte Aggregation Due To Surface Nanobubble Interactions During The Onset Of Thermal Burn Injury, Harrison Steven Seidner

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

Red Blood Cell (RBC) aggregation is an important hemorheological phenomenon especially in microcirculation. In healthy individuals, RBCs are known to aggregate and gravitate toward the faster flow in the center of vessels to increase their throughput for more efficient oxygen delivery. Their aggregation is known to occur during a variety of environmental, pathological, and physiological conditions and is reversible when aggregates are subject to the relatively high shear forces in the circulation. The likelihood that aggregates will monodisperse in flow is dependent on the conditions during which they form. In situations where such aggregates are not sheared to monodispersion their …

Meld Application On Refining Dock Results, Cong Liu Dec 2016

Meld Application On Refining Dock Results, Cong Liu

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

In order to bridge the computational gap between DOCK and MD-based methods, a pipeline was designed to combine external information derived from DOCK with replica exchange molecular dynamics using MELD, an algorithm recently developed by our lab. Our goal was to predict the lowest free energy binding pose within the DOCK ensemble, therefore enabling us to refine DOCK results in cases where the correct structure is incorrectly scored. Our method was tested on 8 such ‘scoring failures’ found in the DOCK database SB2012. Three protocols of extracting structural information from DOCK ensembles were designed and tested. Crystal-like poses were correctly …

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

With the growing need to find alternative clean energy sources to fossil fuels, research into developing efficient fuel cells and batteries stands at the forefront of this grand effort. However, before mass commercialization, fundamental key issues need to be addressed. For example, fuel cells are subject to high catalyst costs and poor durability of the underlying carbon support. As a way to alleviate these issues, we have synthesized ultrathin one-dimensional (1D) alloy nanowires to probe the effect of composition, purity, and one-dimensionality upon the observed overall activity, performance, and durability. In terms of chemical composition, crystalline ultrathin PtM alloy nanowires …

Synthesis And Characterization Of Carbon Nanotube-Metal Chalcogenide/Oxide Heterostructures For Energy-Related Applications, Lei Wang

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

With the increasing strain on existing fossil fuel resources and the serious concerns associated with the environmental impacts on CO2 release through the burning of fossil fuels, clean energy innovation is needed to “get us on the right path†to energy sustainability. Achieving this objective will necessitate a rational design, development, and deployment of schemes to create novel sources of ‘carbon-free’ power using materials with specific and desired functions or properties. In this dissertation, we have attempted to develop two different categories of carbon nanotube (CNT)-based nanoscale heterostructures, namely (a) CNT- CdSe quantum dot (QD) heterostructures and (b) CNT-Li4Ti5O12 (LTO) …

A New Stochastic Regime Switching Model With Time-Varying Regression Coefficients And Error Variances, Xiaojin Dong Dec 2016

A New Stochastic Regime Switching Model With Time-Varying Regression Coefficients And Error Variances, Xiaojin Dong

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

Since the publication of Hamilton’s (1989) seminal work on Markov switching model, a large number of applications have been found in economics and finance. The classical Markov switching models characterize the estimation of parameters in finite state, limited by the pre-specified number of regimes, thus it is restrictive in empirical studies. In this thesis, we develop a stochastic regime switching model, where the model parameters are both categorical and continuous. By assuming conjugate priors and defining stochastic regime switching variables, we derive recursive filtering and smoothing algorithms to estimate the regimes and develop closed-form recursive Bayes estimates of the regression …

The Association Between Romantic Competence And Social Support Behaviors Among Emerging Adult Couples, Vickie Bhatia Dec 2016

What’S Competence Got To Do With It? The Association Between Romantic Competence And Social Support Behaviors Among Emerging Adult Couples | What’S Competence Got To Do With It? The Association Between Romantic Competence And Social Support Behaviors Among Emerging Adult Couples, Vickie Bhatia

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

Research has consistently demonstrated that romantic relationships during emerging adulthood are salient experiences that are important to identity development and set the stage for future intimate relationships. One area of emerging research is on romantic competence, or a set of skills an individual possesses that affect how he/she approaches and negotiates romantic relationships. Although research has begun to examine the association between romantic competence and self-reported relationship behaviors and outcomes, it has not objectively assessed behavioral indicators of competence nor has it examined how romantic competence skills are enacted during couple interactions. The main goal of this dissertation was to …

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

This dissertation examines the ways in which Ahmet Hamdi Tanpınar’s novel, Huzur (1949), Mahmoud Darwish’s prose-poem Memory for Forgetfulness: August, Beirut, 1982 (1995), and Virginia Woolf’s Mrs. Dalloway (1925) manifest a cognitive landscape of crisis in discursive socio-cultural contexts that provide the reader with a critical awareness of worldliness. It argues that the crisis serves as an overarching theme and a structural and thematic principle in determining the conceptual frameworks of the critical thresholds that these works address. The three authors of my study surpass worldless thresholds designated by the crisis by moving through the idea of home, nation, culture, …

Multi-Source Image Integration Towards Solar Forecast, Zhenzhou Peng Dec 2016

Multi-Source Image Integration Towards Solar Forecast, Zhenzhou Peng

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

Accurate prediction of solar energy in short-term and mid-term horizons becomes increasingly important for harvesting solar energy and improving its viability in comparing with fossil fuels. Because clouds are the primary cause of large fluctuations in solar radiation, estimating cloud movements and correlating cloud activities and the variability of solar irradiance are the essential components in short-term or mid-term solar predictions and play a vital role in the subsequent mitigation in responding to potential solar power fluctuations. However cloud detecting and tracking is very challenging due to the volatility and complexity of clouds and expensive meteorological instruments or remote sensing …

Measuring Internet Traffic Manipulation, Anke Li

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

Traffic differentiation---giving better or worse performance to certain classes of Internet traffic---is a well-known but poorly understood traffic management policy. There is active discussion on whether and how ISPs should be allowed to differentiate Internet traffic, but little data about current practices to inform this discussion. Previous work attempted to address this problem for fixed line networks, but at the time of the publication of our work, there was no solution that works in the more challenging mobile environment. In terms of censorship measurement, despite the high perceived value and increasing severity of online information controls, a data-driven understanding of …

Automatic Discovery Of Efficient Divide-&-Conquer Algorithms For Dynamic Programming Problems, Pramod Ganapathi Dec 2016

Automatic Discovery Of Efficient Divide-&-Conquer Algorithms For Dynamic Programming Problems, Pramod Ganapathi

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

This dissertation is an excursion into computer-discovered algorithms and computer-aided algorithm design. In our vision of the not-so-distant future of computing, machines will take the responsibility of designing and implementing most, if not all, machine-specific highly efficient nontrivial algorithms with provable correctness and performance guarantees. Indeed, as the complexity of computing hardware grows and their basic architectures keep changing rapidly, manually redesigning and reimplementing key algorithms for high performance on every new architecture is quickly becoming an impossible task. Automation is needed. We design algorithms that can design other algorithms. Our focus is on auto-generating algorithms for solving dynamic programming …

Securing Web Applications, Riccardo Pelizzi Dec 2016

Securing Web Applications, Riccardo Pelizzi

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

Over the past decade, web application vulnerabilities have become far more common than vulnerabilities in conventional applications. To mitigate them, we approach the problem from two extremes: one that requires no changes to existing applications but is limited to a few well-defined vulnerability classes, and the second that provides a comprehensive solution but requires a re-thinking of web applications. Our first approach mitigates specific vulnerabilities using policies that do not depend on the application logic, and thus require no developer involvement or effort. We target two of the most common high-profile vulnerabilities, namely, cross-site scripting (XSS) and cross-site request forgery …

The Computational Complexity Of The Provision-After-Wait Problem In Healthcare, Gowtham Srinivasan Dec 2016

The Computational Complexity Of The Provision-After-Wait Problem In Healthcare, Gowtham Srinivasan

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

In Provision-after-Wait in Healthcare (PaW), a social planner operating on a constrained budget is required to sponsor medical treatments to a population of patients. Specifically, each patient is allocated to any of the k hospitals to receive a single unit of medical treatment. The cost of treatment depends upon the hospital and is paid for by the planner. Associated with every patient is a set of k non-negative numbers which denote the patients’ preference or intrinsic value towards getting treated in each of the k hospitals. Since the patients do not pay for the treatment and the planner cannot afford …

Novel Spectral Representations And Sparsity-Driven Algorithms For Shape Modeling And Analysis, Ming Zhong Dec 2016

Novel Spectral Representations And Sparsity-Driven Algorithms For Shape Modeling And Analysis, Ming Zhong

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

In this dissertation, we focus on extending classical spectral shape analysis by incorporating spectral graph wavelets and sparsity-seeking algorithms. Defined with the graph Laplacian eigenbasis, the spectral graph wavelets are localized both in the vertex domain and graph spectral domain, and thus are very effective in describing local geometry. With a rich dictionary of elementary vectors and forcing certain sparsity constraints, a real life signal can often be well approximated by a very sparse coefficient representation. The many successful applications of sparse signal representation in computer vision and image processing inspire us to explore the idea of employing sparse modeling …

Self-Control, Context, And Health-Impairing Behaviors: Understanding Addiction Risk, Melissa Auerbach Dec 2016

Self-Control, Context, And Health-Impairing Behaviors: Understanding Addiction Risk, Melissa Auerbach

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

Self-control failure is a potent predictor of unhealthful behaviors such as drinking and smoking and a risk factor for addiction. Although research examining self-control failure among addicted individuals is growing, less is known about non-addicted people who fail at controlling health behavior. Social-cognitive models are often used to examine health behaviors among non-addicted individuals. However, health behavior theories tend to be trait-based and underemphasize the role of context. It is important to take into account the influence of situational factors (e.g. | stress, fatigue, and negative mood) when understanding the association of dispositional self-control and health-impairing behaviors. This study seeks …
