Characterizing 2-Trees Relative To Chordal And Series-Parallel Graphs, Terry A. Mckee

Theory & Applications of Graphs

The 2-connected 2-tree graphs are defined as being constructible from a single 3-cycle by recursively appending new degree-2 vertices so as to form 3-cycles that have unique edges in common with the existing graph. Such 2-trees can be characterized both as the edge-minimal chordal graphs and also as the edge-maximal series-parallel graphs. These are also precisely the 2-connected graphs that are simultaneously chordal and series-parallel, where these latter two better-known types of graphs have themselves been both characterized and applied in numerous ways that are unmotivated by their interaction with 2-trees and with each other.

Toward providing such motivation, the …

Examining The Mechanistic Roles Of Integrin Alpha-6 In Cancer Metastasis., Chase T. Clark

Honors College Theses

Metastasis- the spread of cancer cells from the primary tumor to the surrounding tissues- is responsible for 90% of cancer deaths. Integrin alpha-6 (ITGA6) is a specific transmembrane cell surface protein that functions in cell surface adhesion and signaling. ITGA6 is upregulated in many types of cancers and promotes the migration and invasion of cancer cells to surrounding tissues. It is my objective to determine the mechanism through which ITGA6 facilitates the migration of cancer cells through the extracellular matrix (ECM). These experiments helped to establish the role of ITGA6 in tumor development and provide focus for possible chemotherapeutic treatment. …

Analysis Of Tensegrity Structures Using Abaqus, Kayla M. Allen

Honors College Theses

This project involves modeling and analysis of a tensegrity structure using the finite element approach utilizing the Abaqus software package. A tensegrity structure is a special type of assembly consisting of a series of straight solid members, arranged in various geometrical configurations in three-dimensional space and held together by series of cables. The developed finite element models for several tensegrity structures are included in this thesis report to better describe the project.

Biostatistics, Epidemiology & Environmental Health Sciences: Faculty Publications

Objective:

This study aimed to investigate coronavirus disease (COVID-19) epidemiology in Alberta, British Columbia, and Ontario, Canada.

Methods:

Using data through December 1, 2020, we estimated time-varying reproduction number, R t , using EpiEstim package in R, and calculated incidence rate ratios (IRR) across the 3 provinces.

Spatial Expressions And Consumer Perceptions Of Quantity, Scott D. Swain, Danny Weathers

AMTP Proceedings 2021

Marketplaces and media sources frequently present consumers with information or measurements that involve “extreme” quantities (e.g., the size of the national debt or the number of pounds of plastic in the Earth’s oceans). Often, communicators express these quantities in spatial terms in an effort to influence the perceptual impact of the information (e.g., expressing the national debt in terms of the number of miles it would extend if laid out in paper currency form). Across three experiments, we find evidence that perceptual impact diminishes with spatial dimensionality (e.g., expressing a quantity as a length makes it seem larger than expressing …

Recruitment & Retention Of Students With Disabilities In Extracurricular Stem Activities, Karin Fisher, Peggy Shannon-Baker, Kania Greer, Barbara Serianni, Kayla Fitzgibbons

National Youth Advocacy & Resilience Conference

This presentation will share the research and data the team has collected through two studies on SWD and informal STEM learning environments. We will examine why SWD do not participate in extracurricular STEM activities and what can be done by teachers and club sponsors to mitigate these barriers.

Lag Effects Of Ozone, Pm2.5, And Meteorological Factors On Covid-19 New Cases At The Disease Epicenter In Queens, New York, Atin Adhikari, Jingjing Yin

Biostatistics, Epidemiology & Environmental Health Sciences: Faculty Publications

The influences of environmental factors on COVID-19 may not be immediate and could be lagged for days to weeks. This study investigated the choice of lag days for calculating cumulative lag effects of ozone, PM2.5, and five meteorological factors (wind speed, temperature, relative humidity, absolute humidity, and cloud percentages) on COVID-19 new cases at the epicenter of Queens County, New York, before the governor’s executive order on wearing of masks in public places (1 March to 11 April 2020). Daily data for selected air pollutants and meteorological factors were collected from the US EPA Air Quality System, weather observation station …

Designing Efficient Algorithms For Sensor Placement, Gabriel Loos

Honors College Theses

Sensor placement has many applications and uses that can be seen everywhere you go.These include, but not limited to, monitoring the structural health of buildings and bridgesand navigating Unmanned Aerial Vehicles(UAV).We study ways that leads to efficient algorithms that will place as few as possible sen-sors to cover an entire area. We will tackle the problem from both 2-dimensional and3-dimensional points of view. Two famous related problems are discussed: the art galleryproblem and the terrain guarding problem. From the top view an area presents a 2-D im-age which will enable us to partition polygonal shapes and use graph theoretical results …

An Efficient Algorithm To Test Potential Bipartiteness Of Graphical Degree Sequences, Kai Wang

Theory & Applications of Graphs

As a partial answer to a question of Rao, a deterministic and customizable efficient algorithm is presented to test whether an arbitrary graphical degree sequence has a bipartite realization. The algorithm can be configured to run in polynomial time, at the expense of possibly producing an erroneous output on some ``yes'' instances but with very low error rate.

Nilpotent Graph, Dhiren Kumar Basnet, Ajay Sharma, Rahul Dutta

Theory & Applications of Graphs

In this article, we introduce the concept of nilpotent graph of a finite commutative ring. The set of all non nilpotent elements of a ring is taken as the vertex set and two vertices are adjacent if and only if their sum is nilpotent. We discuss some graph theoretic properties of nilpotent graph.

Field Experiences In The Ether: The Pandemic-Induced Realities Of Learning To Teach, Penny B. Howell, Alice Gnau, Laura Peavley, Caitlyn Workman

Current Issues in Middle Level Education

In the United States during March and April of 2020, more than 50 million K-12 students were impacted by school closures with many forced to engage in online learning for continuity in their 2019-2020 school year. This disruption to K-12 public and private schools reverberated in programs of teacher education around the country. As school-university partners, we wanted to provide opportunities for new teacher candidates to be able to engage in some form of interaction with students and veteran teachers. We drew on the structures and strength of our school-university partnership to build our plan to engage in pandemic-induced, alternative …

Simulating Collaboration In A Blended Course For Preservice Middle Grades Teachers: Attending To Team, Task, And Time, David C. Virtue

Current Issues in Middle Level Education

Collaboration and teamwork are essential aspects of the work of a professional middle level teacher and an integral part of AMLE Standard 5. Preservice teachers typically experience collaborative practices firsthand during field experiences, but the COVID-19 pandemic has caused many schools to shift instruction online thereby limiting the opportunities for teacher candidates to experience daily life in schools. Teacher educators can provide simulated opportunities for candidates to collaborate and engage in teamwork in virtual classroom settings. The author describes ways to simulate teacher collaboration in virtual settings by providing an example of engagements with teacher educators in a middle grades …
