Multistage Homotopy Analysis Method For Solving Nonlinear Integral Equations, H. Jafari, M. A. Firoozjaee

Applications and Applied Mathematics: An International Journal (AAM)

In this paper, we present an efficient modification of the homotopy analysis method (HAM) that will facilitate the calculations. We then conduct a comparative study between the new modification and the homotopy analysis method. This modification of the homotopy analysis method is applied to nonlinear integral equations and mixed Volterra-Fredholm integral equations, which yields a series solution with accelerated convergence. Numerical illustrations are investigated to show the features of the technique. The modified method accelerates the rapid convergence of the series solution and reduces the size of work.

A Global Evaluation Of Ocean Bottom Pressure From Grace, Omct, And Steric-Corrected Altimetry, D. Chambers, Josh K. Willis

Marine Science Faculty Publications

Ocean bottom pressure (OBP) from the Gravity Recovery and Climate Experiment (GRACE) and the Ocean Model for Circulation and Tides (OMCT) are compared globally with OBP computed from altimetry corrected for steric variations from Argo floats from January 2005 to December 2007. Two methods of smoothing the GRACE data are examined. The first uses a standard Gaussian smoother with a radius of 300 km. The second method projects those smoothed maps onto empirical orthogonal functions derived from OMCT in a least squares estimation in order to produce maps that better agree with the physical processes embodied by the model. These …

Insights Into Particle Formation And Remineralization Using The Short-Lived Radionuclide, Thoruim-234, Kanchan Maiti, Claudia R. Benitez-Nelson, Ken O. Buesseler

Faculty Publications

Simple mass balance models are applied to a high resolution ²³⁴Th profile from the northwest Pacific to examine the magnitude, rate, and depth distribution of particle remineralization processes below the euphotic zone (Ez). Here, excess ²³⁴Th (²³⁴Th > ²³⁸U) below the Ez is attributed to fragmentation processes that result in the conversion of sinking to non-sinking particles. By considering particulate organic carbon (POC) to ²³⁴Th ratios on particles, we show that POC flux attenuation is larger than for ²³⁴Th, which we attribute to bacterial and zooplankton consumption of sinking POC. Three case studies are …

Role Of Serotonin (5-Ht) In Hypoxic And Hypercapnic Ventilatory Responses, Tejus A. Bale

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

Breathing is fundamental to life, and responding appropriately to hypercapnic and hypoxic conditions is essential to survival. Abberant respiratory behavior is a feature of a wide variety of clinical conditions, and appears to be central and causative to the progression and outcome of some diseases, including Sudden Infant Death Syndrome (SIDS). Evidence of serotonergic (5-HT) abnormalities within the medulla are amongst the most robust and consistent pathological findings in SIDS victims. It is hypothesized that these underlying brainstem abnormalities precipitate the failure of normal, protective homeostatic responses to physiological stressors. Understanding the mechanisms by which 5-HT modulates the responses to …

Global Genetic Stock Structure Of The Copper (Carcharhinus Brachyurus) And Dusky Sharks (Carcharhinus Obscurus): Interspecific Comparisons And Implications For Management, Martin Tomas Benavides

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

Genetic stock structure information is needed to help delineate management units and monitor trade in sharks, many of which are heavily exploited and declining. Among these, the copper (Carcharhinus brachyurus) and dusky sharks (Carcharhinus obscurus) are considered some of the most vulnerable to overexploitation, given their K-selected life history strategy. The International Union for the Conservation of Nature (IUCN) categorizes the copper shark as “Near-Threatened” globally and the dusky shark as “Vulnerable” globally, with the Northwest Atlantic-Gulf of Mexico population qualifying for “Endangered.” Global mitochondrial stock structure is assessed for both C. brachyurus and C. obscurus by analyzing part of …

Adult Attachment Representations And Secure Base Use And Support In Couple Problem Solving Interactions, Susan Brockmeyer

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

Validity is more than a rich suite of empirical correlates. They have to be the right correlates. In the case of the Adult Attachment Interview, validation includes showing links to the secure base concept, the central concept in Bowlby's and Ainsworth's attachment theory. Important evidence for the AAI's validity comes from longitudinal research linking infant Strange Situation classifications to the same person's AAI classifications 20 years later (e.g. | Waters et al. 2000). In addition, Crowell et al. (2002) provided strong support for the attachment relevance of the AAI by showing that narrative coherence in the AAI is significantly related …

Meta-Analysis Of Fertilization Experiments Indicates Multiple Limiting Nutrients In Northeastern Deciduous Forests, Matthew A. Vadeboncoeur

All Materials

It is widely accepted that nitrogen limits primary production in temperate forests, although co-limitation by N and P has also been suggested, and on some soils Ca and base cations are in short supply. I conducted a meta-analysis to assess the strength of existing experimental evidence for limitation of primary production by N, P, and Ca in hardwood forests of the northeastern United States and southeastern Canada, using data from 35 fertilization experiments in deciduous forests on glaciated soils across the region.

There is strong evidence for N limitation (formal meta-analysis weighted mean response ratio = 1.51, p < 0.01; simple mean = 1.42, p < 0.001). Forest productivity also tends to increase with additions of P (simple mean = 1.15, p = 0.05) and Ca (simple mean = 1.36 p < 0.001). Across all treatments, 85% of response ratios were positive. Multiple-element additions had larger effects than single elements, but factorial experiments showed little evidence of synergistic effects between nutrient additions. Production responses correlated positively with the rate of N fertilization, but this effect was reduced at high rates of ambient N deposition.

Annexin A2 And Microglia/Macrophages In Glioma Progression, Haiyan Zhai

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

Gliomas are highly invasive brain tumors with the occurrence of numerous microglia/macrophages (MG/MP) in and around the tumor. Annexin A2 is overexpressed in many cancers and correlates with increased plasmin activity on the tumor cell surface. Plasmin mediates degradation of extracellular matrix and angiogenesis to facilitate tumor growth. In this study, we used a mouse glioma cell line, GL261-EGFP, and stable clones transfected with an annexin A2 knockdown (annA2KD) construct, GL261-EGFP-annA2KD. We found that the annA2KD decreased glioma cell migration in vitro and decreased membrane-bound plasmin activity. In vivo we injected GL261-EGFP cells into the mouse brain and the glioma …

The Role Of Phospholipase D2 In Golgi-Architecture Maintenance, Vesicular Trafficking And Glucose- Stimulated Insulin Release & Validation Of A Novel Non- Invasive Approach To Functional Β-Cell Mass Quantification, Oladapo Olumoroti Yeku

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

Phospholipase D (PLD) is essential for different aspects of vesicle trafficking and regulated exocytosis in a variety of biological models. PLD1 and PLD2 are the two major mammalian isoforms and both isoforms localize to different organelles where they generate phosphatidic acid (PA), the effector molecule of PLD activity. The role of PLD1 in glucose-stimulated insulin release (GSIR), a form of regulated exocytosis, has been well characterized. Additionally, the role of PLD1 in anterograde vesicle trafficking from the ER to the cis-golgi and from the trans-golgi to the plasma membrane has also been described. The role of PLD2 in GSIR and …

Power Studies Of Regression-Based Linkage Methods For Selected Sibpairs In The Presence Of Epistasis, Chengrui Huang

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

Although the ubiquitousness of epistasis, or gene-gene interactions, is widely acknowledged, many commonly used quantitative-trait-locus (QTL) linkage analysis methods have been developed without explicitly modeling any dominance or epistasis effects. The power of regression-based linkage methods was investigated in this paper under a range of two-locus models of various degrees and types of epistasis. A quantitative trait is studied usually because of its association with some complex disease of interest. Therefore we introduced selection through disease affected probands, which has commonly been used in qualitative trait studies, into our QTL analysis, and compared it to random selection and selection based …

Development Of A Quantitative Assay For Mitochondrial Fusion And Characterization Of A Lipid Signaling Pathway On The Mitochondrial Surface, Huiyan Huang

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

Mitochondria continuously undergo fusion and fission, the relative rates of which define their morphology. Mitochondrial fusion is currently assayed by fusing together cells expressing GFP or RFP in their mitochondria and then scoring the frequency of cells with yellow mitochondria (representing fused green and red mitochondria). However, this assay is labor intensive and only semi-quantitative. I developed a reporter system consisting of split fragments of Renilla luciferase and YFP fused to mitochondrial matrix-targeting sequences and to leucine zippers to trigger dimerization. The assay enables fusion to be quantitated both visually for individual cells and on a population level using chemiluminescence, …

Association Of Blood Dpp5 Level With Cancer Type, Stage, And Survival, Mazyar Javid Roozi

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

Introduction: Membrane-bound dipeptidyl peptidase 5 (DPP5) has been linked to tumor invasion and metastasis processes. Its recent isolation as a soluble protein from plasma may indicate a potential role as a biomarker and prognostic factor for tumors, and as a potential therapeutic target. This study aimed to measure the plasma levels of DPP5 and the related member of the family, DPP4, in healthy subjects and cancer patients, and to determine their clinical significance.Methods: Enzyme-linked immunosorbent assays (ELISAs) for measuring plasma DPP5 and DPP4 were developed and clinical correlations were made.Results: ELISAs were validated to be sensitive and specific. In the …

Genetic Analyses Of The Terminal Protein (Vpg) And Of Spacer Ii In The 5'-Nontranslated Region Of Poliovirus Rna, Nicolai Kolb

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

VPg is a small protein (20-30 amino acids long), which is present in every virus of the Picornaviridae family. A hydroxyl group of tyrosine at position 3 of VPg is covalently linked to the 5'-terminal UMP of genomic Poliovirus RNA via a phosphodiester bond and is crucial for virus viability. Poliovirus mutants in whom this tyrosine is substituted with a phenylalanine are quasi-infectious if threonine is present at position 4, which also has a hydroxyl group. The aim of the first part of this research project was to determine whether serine can also serve as an acceptor of UMP. An …

Design And Biological Evaluation Of New Nsaids Based Anticancer Agents And Their Controlled Release From An Addressable Hydrogel Based Delivery System, Stancy Jana Joseph

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

In recent years scientific and technological advancements have been made in the research and development of controlled drug delivery systems and new chemopreventive agents. For many potential drug candidates a modified in vivo drug release is desired to improve efficacy, sustain drug effect or minimize drug toxicity. To tackle the problems associated with the delivery of drug, delivery systems (DDS) with multiple functionalities such as environment-sensitive drug release mechanisms have motivated the biomedical community as well as materials chemists for more than a decade. Polymeric drug delivery systems have been extensively studied in an attempt to achieve modified drug release. …

A Multi-Class Classification Using Ensembles Of Multinomial Logistic Regression Models, Kyewon Lee

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

This research proposes a method for multi-way classification problems using ensembles of multinomial logistic regression models. A multinomial logit model is used as a base classifier in ensembles from random partitions of predictors. The multinomial logit model can be applied to each mutually exclusive subset of the feature space without variable selection. By combining multiple models the proposed method can handle a huge database without a parametric constraint needed for analyzing high-dimensional data,and the random partition can improve the prediction accuracy by reducing the correlation among base classifiers. The proposed method is implemented using R and the performance including overall …

Probing The Mesolimbic Dopamine Reward System: A Common Neurocircuitry In Substance Abuse And Schizophrenia, Eunjoo Lee

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

Substance abuse is more prevalent among patients with schizophrenia than in the general population. Interestingly, the pathophysiology of schizophrenia is thought to share many overlapping features with drug addiction, including disruption of the mesolimbic dopaminergic pathway. My thesis work was aimed at investigating drug-induced alterations in dopamine function that leads to addiction-related behavior using animal models of substance abuse. In the first part of my studies, I combined small animal imaging with behavioral tests to probe the effects of abused inhalants on overall brain activity and the dopaminergic system in rats. These studies lead me to the second part of …

Dna Damage Response Activates Interferon Signaling, Sabrina Ewa Racine Brzostek

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

The DNA damage response occurs in response to breaks in DNA and can elicit cell signaling pathways that result in cell cycle arrest, DNA repair, or apoptosis in order to maintain the integrity of the genome. The replication of viruses activates the host DNA damage response and many of these viruses have evolved mechanisms to inhibit apoptosis. To understand better the link between DNA damage and cellular defense, the effects of agents that create double-stranded DNA breaks were evaluated on cellular gene expression. Etoposide, a chemotherapeutic drug used to treat various cancers, causes cell cycle arrest and death by apoptosis. …

How Does Groundwater Impact Eelgrass In Long Island? The Role Of Nitrogen And Herbicide In Reducing Eelgrass Growth,Survival And Photosynthetic Efficiency., Brooke Shannon Rodgers

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

Eelgrass communities in the Peconic estuary of Long Island NY have been in decline for several decades prompting resource managers to reduce nitrogen loads into the estuary. Despite improved water quality in recent years, eelgrass continues to decline. This lack of response has caused the management agencies to suggest that seepage of groundwater contaminated with herbicides such as Diuron and high nitrate from regions with a long history of agriculture may be to blame. We performed two types of manipulative experiments during the summer of 2009 to assess the possible impacts of groundwater on eelgrass growth and survival. We exposed …
