Sub-Cloning, Expression, And Purification Of The Wild Type And Mutated Sigma-1 Receptor, Christopher Koch Jan 2019

Sub-Cloning, Expression, And Purification Of The Wild Type And Mutated Sigma-1 Receptor, Christopher Koch

Undergraduate Honors Thesis Collection

The Sigma-1 receptor (S1R) is an important pharmaceutical target that has been linked to several neurological diseases and drug addiction. It has been proposed that multimerization of S1R is important for attenuating its interactions with the dopamine transporter (DAT) and that S1R agonists promote dissociation to a monomeric form necessary for DAT interaction. This project aims to assess the role of the N-terminal transmembrane domain in oligomerization and binding activity of the mammalian Sigma-1 receptor (S1R). N-terminal truncations lacking the transmembrane domain and the E102Q variant, which displays altered activity and cellular localization, were expressed, purified in order to determine …

Hackett, Gregory A. Kopp, Gareth Morgan, Christopher G. Guglielmo, Roi Gurka Jan 2019

Flow Features Of The Near Wake Of The Australian Boobook Owl (Ninox Boobook) During Flapping Flight Suggest An Aerodynamic Mechanism Of Sound Suppression For Stealthy Flight, Jonathan Lawley, Hadar Ben-Gida, Krishnan Krishnamoorthy, Erin E. Hackett, Gregory A. Kopp, Gareth Morgan, Christopher G. Guglielmo, Roi Gurka

Physics and Engineering Science

The mechanisms associated with the ability of owls to fly silently have been the subject of scientific interest for many decades and may be relevant to bioinspired design to reduce noise of flapping and nonflapping flying devices. Here, we characterize the near wake dynamics and the associated flow structures produced during flight of the Australian boobook owl (Ninox boobook). Three individual owls were flown at 8 ms-1 in a climatic avian wind tunnel. The velocity field in the wake was sampled at 500 Hz using long-duration high-speed particle image velocimetry (PIV) while the wing kinematics were imaged simultaneously using high …

Guided by Bandura’s social cognitive theory, the purpose of this mixed-methods study was to examine the relationship between general education teacher self-efficacy and academic achievement among students with disabilities. Quantitative data were collected from 23 general education teachers using the Teacher Efficacy for Inclusive Practice Scale and Collection of Classroom Assessment Data Form, in which general education teachers reported student academic achievement data in the form of end-of-chapter and end-of–unit summative quiz and test scores. A multiple linear regression analysis was used to …


Recruitment Strategies For A Sustainable Pipeline Of African American College Graduates As Civil Servants, Owen Wilbert Muldrow, Jr. Jan 2019

Recruitment Strategies For A Sustainable Pipeline Of African American College Graduates As Civil Servants, Owen Wilbert Muldrow, Jr.

Walden Dissertations and Doctoral Studies

Government leaders have not been successful in their strategies for developing a pipeline of African American college students to address the absence of African American representation in civil service management positions. Increasing African American representation among civil service personnel may produce a government workforce that reflects American society, which may promote equitable and responsive solutions in serving public interests. The purpose of this qualitative modified Delphi study was to build consensus among a nationwide expert panel of government-affiliated talent managers as to strategies for creating a sustainable civil service pipeline of annual graduating classes of African American collegians. The research …

Equitable Learning Assessments For Students With Disabilities (Neqmap Thematic Review), Anannya Chakraborty, Amit Kaushik, Unesco Office Bangkok And Regional Bureau For Education In Asia And The Pacific

Assessment and Reporting

Asia-Pacific is home to 690 million persons with a disability. Persons with disabilities experience lower educational opportunities as children and therefore also face fewer opportunities as adults. Children with disabilities experience barriers to participating in education that result in enrolment rate drops of up to 53 per cent between primary and secondary education, making it increasingly difficult for persons with disabilities to secure employment. Low participation rates and other barriers have a serious impact on the learning achievement and learning outcomes of learners with disabilities. This thematic review provides an overview of the existing inclusive education policies and practices in …

Hard: A Heterogeneity-Aware Replica Deletion For Hdfs, Hilmi Egemen Ciritoglu, John Murphy, Christina Thorpe Jan 2019

Hard: A Heterogeneity-Aware Replica Deletion For Hdfs, Hilmi Egemen Ciritoglu, John Murphy, Christina Thorpe

Articles

The Hadoop distributed fle system (HDFS) is responsible for storing very large datasets reliably on clusters of commodity machines. The HDFS takes advantage of replication to serve data requested by clients with high throughput. Data replication is a trade-of between better data availability and higher disk usage. Recent studies propose diferent data replication management frameworks that alter the replication factor of fles dynamically in response to the popularity of the data, keeping more replicas for in-demand data to enhance the overall performance of the system. When data gets less popular, these schemes reduce the replication factor, which changes the data …

The data is stored in a highly structured format with the added SPARQL protocol and RDF Query Language (SPARQL) endpoint to allow users to query its knowledge base.


Forecasting Anomalous Events And Performance Correlation Analysis In Event Data, Sonya Leech [Thesis] Jan 2019

Forecasting Anomalous Events And Performance Correlation Analysis In Event Data, Sonya Leech [Thesis]

Dissertations

Classical and Deep Learning methods are quite common approaches for anomaly detection. Extensive research has been conducted on single point anomalies. Collective anomalies that occur over a set of two or more durations are less likely to happen by chance than that of a single point anomaly. Being able to observe and predict these anomalous events may reduce the risk of a server’s performance. This paper presents a comparative analysis into time-series forecasting of collective anomalous events using two procedures. One is a classical SARIMA model and the other is a deep learning Long-Short Term Memory (LSTM) model. It then …

Classically Biased: A Quantitative Analysis Of Gender & Writing Styles In Classical Literature, Madeleine Rose Delcambre

Honors Theses

This thesis is a first attempt in assessing patterns related to gender in classical literature prior to the 21st century, specifically looking at the way writing styles and language di↵er among female and male authors; e.g., sentence structuring, lexical diversity, and dictionary similarities. Further topics of analysis included gender distribution and sentiment within the novels themselves. Seventy-eight open-source novels were used in the analysis, with thirty-one books by female authors and forty-seven by male authors. Data from the novels was acquired using Python, natural language processing, and the Natural Language Toolkit (NLTK). Graphs and visuals were then created to summarize …

Synthesis Of A Novel Tetradentate Ligand And Its Copper Complex For Redox Shuttle Applications, Joseph T. Vaughan Jan 2019

Synthesis Of A Novel Tetradentate Ligand And Its Copper Complex For Redox Shuttle Applications, Joseph T. Vaughan

Honors Theses

With growing energy demands, alternatives to the traditional non-renewable fuel sources are currently being explored. Of these alternative fuel sources, solar energy, particularly dye-sensitized solar cells (DSSC), have garnered considerable interest. Traditional redox mediators within these solar cells have been triiodide/iodide couples, which pose several complications due to their corrosiveness, absorption in the visible range, and efficiency, motivating the development of better redox couples for next generation DSSCs. Thus, transition metal complexes have rapidly gained traction as a potential replacement for this traditional I-/I3- based system. In this study, a novel tetradentate ligand framework and its copper and nickel complexes …


Design And Development Of Chemically And Biologically Stable Salvinorin-Based Ligands For Opioid Receptors, Tanner Neilson Jan 2019

Design And Development Of Chemically And Biologically Stable Salvinorin-Based Ligands For Opioid Receptors, Tanner Neilson

Honors Theses

The number of opioid prescriptions as a method in pain management increased dramatically in the mid 1990’s following Dr. James Campbell’s 1995 Presidential address to the American Pain Society, where he called for patient pain to be included as a vital sign. The rapid increase in prescriptions in the early 2000’s coupled with a massive effort by pharmaceutical companies to downplay the addictiveness of these drugs has led to a consistent increase in opioid-related drug overdoses, with 47,600 of 70,237 drug related deaths involving opioids in 2017. Opioid analgesics most commonly act upon the mu-opioid receptor (MOR), which is one …


On A Generalization Of Lucas Numbers, Skylyn Olyvia Irby Jan 2019

On A Generalization Of Lucas Numbers, Skylyn Olyvia Irby

Honors Theses

In this paper, we consider a generalization of Lucas numbers. Recall that Lucas numbers are the sequence of integers defined by the recurrence relation: L_n = L_{n−1} + L_{n−2} with the initial conditions L_1 = 1 and L_2 = 3(or L_0 = 1 and L_1 = 3 if the first subscript is zero). That is, the classical Lucas number sequence is 1, 3, 4, 7, 11, 18, .... The goal of the present paper is to study properties of certain generalizations of the Lucas sequence. In particular, we consider the following generalizations of the sequence: l_n = al_{n−1} + l_{n−2} …


A Self-Study Of Purposeful Grouping For Collaborative Learning, Allie Cameron Roberson Jan 2019

A Self-Study Of Purposeful Grouping For Collaborative Learning, Allie Cameron Roberson

Honors Theses

Groups are commonly seen and used in mathematics classrooms. During my time student teaching, I have used what I call, “timely, flexible, dynamic, purposeful” groups. I call groups “purposeful” when there is a defined purpose for using them, there is an ability to change groups when needed, and the groups are formed from a timely assessment. During my self-study, I have looked at how I used these purposeful groups in my classroom, and how it differs from common group-types. I give an example of a specific class period, how I used the data from the opener to form purposeful groups, …

Does The Tax Code Favor Robots?, Daniel J. Hemel Jan 2019

Does The Tax Code Favor Robots?, Daniel J. Hemel

Coase-Sandor Institute for Law & Economics Research Paper Series

In recent months, a number of scholars and commentators have articulated versions of the following argument: (1) U.S. tax law favors capital over labor;1 (2) Robots are capital; 2 (3) Therefore, U.S. tax law favors robots over labor.3 Three implications tend to be drawn from this syllogism: (a) that U.S. tax law leads to inefficient investments in automation;4 (b) that automation—because it is capital-intensive and capital is tax-favored—will result in a reduction in tax revenues;5 and (c) that policymakers should respond to the automation trend either by imposing explicit taxes on robots or by raising taxes …

A Constructive Approach To Higher Homotopy Operations, David Blanc, Mark W. Johnson, James M. Turner Jan 2019

A Constructive Approach To Higher Homotopy Operations, David Blanc, Mark W. Johnson, James M. Turner

University Faculty Publications and Creative Works

In this paper we provide an explicit general construction of higher homotopy operations in model categories, which include classical examples such as (long) Toda brackets and (iterated) Massey products, but also cover unpointed operations not usually considered in this context. We show how such operations, thought of as obstructions to rectifying a homotopy-commutative diagram, can be defined in terms of a double induction, yielding intermediate obstructions as well.

A Gis-Based Modeling Approach To High-Resolution Anthropogenic Heat Flux And Building Energy Demand In Los Angeles, Yuanfan Zheng Jan 2019

A Gis-Based Modeling Approach To High-Resolution Anthropogenic Heat Flux And Building Energy Demand In Los Angeles, Yuanfan Zheng

All-Inclusive List of Electronic Theses and Dissertations

Anthropogenic heat flux (Q f ) originates from energy consumption in buildings, industrial plants, vehicle exhaust, and human metabolism. Q f is an important component of the urban Surface Energy Balance (SEB) system and a key to understanding many urban environmental issues. Climate change affects building energy consumption in many ways, and building energy consumption is the largest contributor to Q f in many cities. One of these contributions comprises changes in heating and cooling demands in buildings. The increase in annual energy use in cities results in more carbon emissions and constitutes a great challenge to urban sustainability because …
