Essays On Collective Contests And Bargaining., Dhritiman Gupta Dr. Jul 2021

Essays On Collective Contests And Bargaining., Dhritiman Gupta Dr.

Doctoral Theses

This thesis consists of three theoretical essays in Microeconomics. The first two essays analyze the properties of a particular class of prize sharing rules groups may employ in a situation of a collective contest with another group, over a private good. The third essay studies a situation of multi-lateral bargaining, where a buyer wants to successfully bargain with multiple sellers, who own an input each, so that he can implement a grand project. The main focus of the thesis is to theorize about and generate hypotheses of the situations summarized above. In the first chapter, we consider a situation of …


Dealing With Classification Irregularities In Real-World Scenarios., Payel Sadhukhan Dr. Jul 2021

Dealing With Classification Irregularities In Real-World Scenarios., Payel Sadhukhan Dr.

Doctoral Theses

Data processing by the human sensory system comes naturally. This processing, commonly denoted as pattern recognition and analysis are carried out spontaneously by humans. In day to day life, in most cases, decision making by humans come without any conscious effort. From the middle of the past century, humans have shown interest to render their abstraction capabilities (pattern recognition and analysis) to the machine. The abstraction capability of the machine is ’machine intelligence’ or ’machine learning’ [87].The primary goal of machine learning methods is to extract some meaningful information from the ’data’. Data refers to the information or attributes that …


Relative Infrasound Calibration Of Microphones With Application To Outdoor Vector Intensity Measurements, Francisco Javier Irarrazabal Oliva Jul 2021

Relative Infrasound Calibration Of Microphones With Application To Outdoor Vector Intensity Measurements, Francisco Javier Irarrazabal Oliva

Theses and Dissertations

This thesis describes the phase and amplitude correction of 12.7 mm diameter, Type-1 microphones for three frequency bands, including within the infrasound regime, and its application to acoustic measurements. Previous data stem from acoustic intensity measurements using two-dimensional, four-microphone probes, which emphasized the requirement of having the acoustic phase and amplitude difference be much greater than the interchannel mismatch. Although correcting the amplitude/phase is well-known, obtaining the necessary transfer functions in the infrasound regime is challenging because (1) signal-to-noise ratios are often poor, (2) long measurement times are required for averaging, and (3) microphone responses vary significantly across these low …

Casillas-Ituarte, Concepcion Jimenez-Lopez, Dennis A. Bazylinski, Steven K. Lower, Brian H. Lower

Life Sciences Faculty Research

Magnetotactic bacteria (MTB) biomineralize intracellular magnetite (Fe3O4 ) crystals surrounded by a magnetosome membrane (MM). The MM contains membrane-specific proteins that control Fe3O4 mineralization in MTB. Previous studies have demonstrated that Mms13 is a critical protein within the MM. Mms13 can be isolated from the MM fraction of Magnetospirillum magneticum AMB-1 and a Mms13 homolog, MamC, has been shown to control the size and shape of magnetite nanocrystals synthesized in-vitro. The objective of this study was to use several independent methods to definitively determine the localization of native Mms13 in M. magneticum AMB-1. Using Mms13-immunogold labeling and transmission electron microscopy …

An Εhf And Δ18o Isotopic Study Of Zircon Of The Mount Osceola And Conway Granites, White Mountain Batholith, New Hampshire: Deciphering The Petrogenesis Of A-Type Granites, Javier Fabian Matos Strauss

Theses and Dissertations

A-type granites form in anorogenic settings and typically have high REE concentrations, K2O, Na2O, SiO2, FeOtotal, but low contents of Al2O3, MgO, CaO compared to other granite types. They have been divided in two groups according to their geochemical characteristics: differentiates of mantle-derived magmas (A1), and granites that are the result of melting depleted, lower crust (A2). The two largest A-type granites of the Mesozoic White Mountain Batholith of New Hampshire are the Mount Osceola and Conway granites. Electron microprobe analyses of biotite and amphibole in both granites are similar to those in other A-type granites: Fe-rich, but low MgO, …

Improving Communication Of Uncertainty And Risk Of High-Impact Weather Through Innovative Forecaster Workshops, Brian A. Colle, Rosemary Auld, Kenneth Johnson, Christine O'Connell, Temis G. Taylor, Joshua Rice

Environment and Society Faculty Publications

It is challenging to communicate uncertainty for high-impact weather events to the public and decision-makers. As a result, there is an increased emphasis and training within the National Weather Service (NWS) for “impact-based decision support.” A Collaborative Science, Technology, And Research (CSTAR) project led by Stony Brook University (SBU) in collaboration with the Alan Alda Center for Communicating Science, several NWS forecast offices, and NWS operational centers held two workshops at SBU on effective forecast communication of probabilistic information for high-impact weather. Trainers in two 1.5-day workshops helped 15–20 forecasters learn to distill their messages, engage audiences, and more effectively …

An inevitable megathrust earthquake is expected in the Cascadia subduction zone that will affect the population of the coast of southwestern British Columbia and the northwest of the United States. In this active tectonic margin, the Juan de Fuca oceanic plate is subducting beneath the North American continental plate, causing unevenly distributed seismic activity. The major goal of this geophysical research project is to study the tectonic structures of the Cascadia subduction zone in order to comprehend the geology of the region and investigate the seismic hazards. The primary objective of this project is to develop a geophysical database of …


Nonlinear Ultrafast Excitation And Two-Dimensional Terahertz Spectroscopy Of Solids, Brittany E. Knighton Jul 2021

Nonlinear Ultrafast Excitation And Two-Dimensional Terahertz Spectroscopy Of Solids, Brittany E. Knighton

Theses and Dissertations

Ultrafast spectroscopy allows us to probe and understand material properties. With it, we can measure phonon-polaritons (optical phonons coupled with light) and the resulting dispersion curve in lithium niobate. Customizing the excitation source in ultrafast measurements can excite phonon modes to large amplitudes, allowing the experimental exploration of the Potential Energy Surface in solids. However, stronger pump fluences and bigger signal isn't always the answer in ultrafast spectroscopy. When sample signals and their nonlinear and mechanisms cannot be distinguished with 1D measurements, simple 2D THz measurements are a great place to start searching for distinct factors as was the case …

Method Development Of Standard Dilution Analysis On Molecules And Dissolution Studies Of Ibuprofen Tablets Along With Common Beverage Constituents, Scott Richardson

Master of Science in Chemical Sciences Theses

The United States Pharmacopeia sets the standards for the manufacturing, storage, and analysis of medicinal formulations. One analysis, dissolution testing evaluates the rate at which the medicinal formulation forms a solution to predict in vivo drug release. Dissolution testing on ibuprofen tablets alone and in the presence of ascorbic acid or caffeine was performed to mimic the administration using orange juice or caffeinated soft drinks to assess their impact on the dissolution rate of ibuprofen. Results using the external calibration method produced a dissolution rate of ibuprofen that decreased 4% in the presence of ascorbic acid and increased 1% in …


Data From: Drivers Of Zooplankton Community Composition In A Novel Ecosystem: Hawai’I Mangroves As A Case Study, Casey L. Lewis, Elise F. Granek Jul 2021

Data From: Drivers Of Zooplankton Community Composition In A Novel Ecosystem: Hawai’I Mangroves As A Case Study, Casey L. Lewis, Elise F. Granek

Environmental Science and Management Datasets

Management of established non-native plants is challenging because removal is expensive and can produce negative consequences, yet establishment can create novel ecosystems. Red mangrove propagules were introduced to Moloka'i, Hawai’i in 1902 to mitigate the effects of soil erosion and have since spread along the coast and to adjacent islands creating novel habitat. We compared zooplankton communities between novel mangrove and historical non-mangrove habitat both within fishponds and along open coastline to examine environmental factors, including mangrove presence, affecting zooplankton community composition.

Community composition patterns were driven by lunar cycle and site characteristics, including fishpond structure, mangrove and open coast …


An Introduction To Generalized Entropy And Some Quantum Applications, Paul Bracken Jul 2021

An Introduction To Generalized Entropy And Some Quantum Applications, Paul Bracken

School of Mathematical and Statistical Sciences Faculty Publications and Presentations

The concept of generalized entropy is introduced and some of its properties are studied. Irreversible time evolution can be generated by a non-Hermitian superoperator on the states of the system. The case when irreversibility comes about from embedding the system in a thermal reservoir is looked at. The time evolution is found compatible both with equilibrium thermodynamics and entropy production near the final state. Some examples are presented as well as a longer introduction as to how this might play a role in the black hole information loss paradox.

Search For Anisotropic Gravitational-Wave Backgrounds Using Data From Advanced Ligo And Advanced Virgo's First Three Observing Runs, R. Abbott, T. D. Abbott, S. Abraham, F. Acernese, K. Ackley, Teviet Creighton, Mario C. Diaz, Soma Mukherjee, Volker Quetschke, Karla E. Ramirez, W. H. Wang

Physics and Astronomy Faculty Publications and Presentations

We report results from searches for anisotropic stochastic gravitational-wave backgrounds using data from the first three observing runs of the Advanced LIGO and Advanced Virgo detectors. For the first time, we include Virgo data in our analysis and run our search with a new efficient pipeline called PyStoch on data folded over one sidereal day. We use gravitational-wave radiometry (broadband and narrow band) to produce sky maps of stochastic gravitational-wave backgrounds and to search for gravitational waves from point sources. A spherical harmonic decomposition method is employed to look for gravitationalwave emission from spatially-extended sources. Neither technique found evidence of …


Synthesis And Utility Of Chiral And Achiral Trifluoroacetamide Substrates In Cycloaddition Reactions, Isaac Theodore Smith Jul 2021

Synthesis And Utility Of Chiral And Achiral Trifluoroacetamide Substrates In Cycloaddition Reactions, Isaac Theodore Smith

Theses and Dissertations

In this document we report the synthesis, characterization, and utility of a chiral amidoacrylate substrate. This substrate features a reactive alkene that can be used in a variety of reactions. [3+2]-Cycloaddition reactions to form pyrroloindolines are shown to proceed with excellent diastereoselectivity (>20:1) and yield (86%). [3+2]-Reactions allow for the stereoselective construction of the pyrroloindoline backbone common in many natural products. Diels-Alder reactions catalyzed by TiCl4 show high yields (82%) with ~2:1 diastereoselectivity. Cyclopropanation reactions proceed in moderate yield (71%) and diastereoselectivity (~3:1). Both Diels-Alder and cyclopropanation reactions utilizing the chiral amidoacrylate substrate serve to stereoselectively produce unnatural amino …


Protein Conformational Stability Enhancement Through Pegylation And Macrocyclization, Qiang Xiao Jul 2021

Protein Conformational Stability Enhancement Through Pegylation And Macrocyclization, Qiang Xiao

Theses and Dissertations

PEGylation can improve the pharmacokinetic properties of protein therapeutics via decreasing renal clearance and shielding the protein surface from proteases, antibody neutrailization, and aggregation. Conformational stability enhancement can provide criteria for the identification of optimal sites for PEGylation, but how PEG influence the noncovalent interactions from the surface of proteins has not been well illustrated. Macrocyclization can effectively enhance the conformational stability of small peptides and large proteins. Combination of PEG-based conformational stability enhancement and macrocyclization-based conformational constraint has not been explored. Macrocycliziation has been employed to stabilize protein tertiary structures, but there are no general guidelines for interhelical staple …


Nanoorthogonal Surface Modifications Of Gold Nanoparticles And Nanoclusters Through Strain-Promoted Cycloaddition Chemistry, Praveen N. Gunawardene Jul 2021

Nanoorthogonal Surface Modifications Of Gold Nanoparticles And Nanoclusters Through Strain-Promoted Cycloaddition Chemistry, Praveen N. Gunawardene

Electronic Thesis and Dissertation Repository

This thesis explores the preparation of thiolated gold nanoparticles (AuNPs) and thiolated gold nanoclusters (AuNCs) capable of undergoing post-assembly surface modifications using two common “bioorthogonal” click reactions: the strain-promoted alkyne-azide cycloaddition (SPAAC) reaction (which occurs between a strained-alkyne and an azide) and the strain-promoted alkyne-nitrone cycloaddition (SPANC) reaction (which occurs between a strained-alkyne and a nitrone). Due to their rapid and modifiable reaction kinetics, high chemoselectivity, and stability of the reactive partners, these reactions were originally designed to tether functional substrates to biologically sensitive biomolecules, without altering their structure or perturb the biologically sensitive environments in which they …


Fuzzy And Probabilistic Rule-Based Approaches To Identify Fault Prone Files, Piyush Kumar Korlepara Jul 2021

Fuzzy And Probabilistic Rule-Based Approaches To Identify Fault Prone Files, Piyush Kumar Korlepara

Electronic Thesis and Dissertation Repository

Most software fault proneness prediction techniques utilize machine learning models which act as black boxes when performing predictions. Software developers cannot obtain any insights as to why such trained models reached their conclusions when applied to new data. This leads to a reduced confidence in accepting the prediction results while applying the model in complex systems. In this thesis, we propose two rule-based and programming language-agnostic fault proneness prediction techniques. The first technique utilizes fuzzy reasoning, while the second utilizes Markov Logic Networks. The rules operate on facts that are produced by harvesting and postprocessing raw data extracted from the …

Degumming Of Hemp Fibers Using Combined Microwave Energy And Deep Eutectic Solvent, Bulbul Ahmed Jul 2021

Degumming Of Hemp Fibers Using Combined Microwave Energy And Deep Eutectic Solvent, Bulbul Ahmed

LSU Master's Theses

Hemp is considered as one of the sustainable agricultural fiber materials. Degumming or surface modification of hemp bast is needed to produce single fibers for ensuing textile and industrial applications. The traditional degumming process necessitates a high amount of alkali, which causes detrimental environmental pollution. This study offers a new method to degum hemp fibers with reduced use of harmful alkali and precious water resources. In this work, hemp bast fibers were degummed by using combined microwave energy and deep eutectic solvent (DES). The properties of hemp fibers manufactured by this method were investigated and compared with the traditional alkali …


On The Estimation Of Heston-Nandi Garch Using Returns And/Or Options: A Simulation-Based Approach, Xize Ye Jul 2021

On The Estimation Of Heston-Nandi Garch Using Returns And/Or Options: A Simulation-Based Approach, Xize Ye

Electronic Thesis and Dissertation Repository

In this thesis, the Heston-Nandi GARCH(1,1) (henceforth, HN-GARCH) option pricing model is fitted via 4 maximum likelihood-based estimation and calibration approaches using simulated returns and/or options. The purpose is to examine the benefits of the joint estimation using both returns and options over the fundamental returns-only estimation on GARCH models. From our empirical studies, with the additional option sample, we can improve the efficiency of the estimates for HN-GARCH parameters. Nonetheless, the improvements for the risk premium factor, both from empirical standard errors, and sample RMSEs, are insignificant. In addition, option prices are simulated with a pre-defined noise structure and …


40 Sets Of Strong Ground Motion Records Convey All Design Response Spectrums Located In Tartous, Syria, Dr. Seraj Jdyd Jul 2021

40 Sets Of Strong Ground Motion Records Convey All Design Response Spectrums Located In Tartous, Syria, Dr. Seraj Jdyd

Journal of the Arab American University مجلة الجامعة العربية الامريكية للبحوث

Selecting seismic records in Global Standards is, until now, based on matching design response spectrum, where records should have seismological characteristics similar to the expected earthquake for the considered site (magnitude, distance, fault mechanism and soil conditions). Then it is necessary to scale these records to match the intensity of the earthquake expected for the site. Generally, scaling can be made by ground motions uniform scaling in time domain to best match (in average) the target spectrum within a period range of interest. Design ground motions are typically prescribed by smooth response spectra. But it is preferred to use a …

Morphology Transformation Of Foldamer Assemblies Triggered By Single Oxygen Atom On Critical Residue Switch, Byung-Chang Oh, Eunyoung Yoon, Jintaek Gong, Jaewook Kim, Russell W. Driver, Yongjun Kim, Woo Youn Kim, Hee-Seung Lee

Chemistry and Physics Faculty Articles

The synthesis of morphologically well-defined peptidic materials via self-assembly is challenging but demanding for biocompatible functional materials. Moreover, switching morphology from a given shape to other predictable forms by molecular modification of the identical building block is an even more complicated subject because the self-assembly of flexible peptides is prone to diverge upon subtle structural change. To accomplish controllable morphology transformation, systematic self-assembly studies are performed using congener short β-peptide foldamers to find a minimal structural change that alters the self-assembled morphology. Introduction of oxygen-containing β-amino acid (ATFC) for subtle electronic perturbation on hydrophobic foldamer induces a previously inaccessible solid-state …

The book is dedicated to the 80th anniversary of the Reserve and the 90th birthday of Yuri Gorelov (1931—2018), an extraordinary naturalist who worked in Badkhyz in 1956—1978. His own documentary stories, …


Atomic Photoionization By Multiple Temporal Pairs Of Slits, Jean Marcel Ngoko Djiokap Jul 2021

Atomic Photoionization By Multiple Temporal Pairs Of Slits, Jean Marcel Ngoko Djiokap

Department of Physics and Astronomy: Faculty Publications

We study interactions between multiple temporal pairs of slits in coherent control of photoionization of S-state atoms using a pulse train of N + 1 pairs evenly delayed in time by τ , in which the two pulses in a pair with a delay τ0 are counter-rotating circularly polarized. For interacting two double-slit experiments, while Ramsey interference between two identical Archimedean spirals yields pairs of principal spirals, interference of two spirals with opposite handedness does not lead to spirals, but instead to crocodile-eye-like patterns with nictares. For more than two interacting experiments, the resulting patterns turn out just to …
