Agent‐Based Modeling of Fibrin Fiber Network Formation

Presenter: Key Crosley (UCO) | 1:00–1:15 pm

Abstract: Blood clots are held together by a network of fibrin fibers. Our agent‐based model aims to render accurate fibrin interactions to better understand network formation.

Systematic Analysis of Parameter Variations in a Stochastic Fibrin Fiber Degradation Model

Presenter: Austin Segrest (UCO) | 1:20–1:35 pm

Abstract: Fibrinolysis is the process of breaking down fibrin, the main protein in blood clots. This process is regulated by plasmin, activated from plasminogen by tissue plasminogen activator (tPA). We present a stochastic model using the Gillespie algorithm to simulate fibrin fiber degradation. The model predicts cleavage time and success rate under various conditions. Results are compared to in vitro experiments to better understand fibrinolysis mechanisms.

Mathematics and Community Engagement (Forensic Science Auditorium)

Presenter: Lisa Marano (WCU) | 3:45–4:45 pm

Abstract: First-year seminars, learning communities, service-learning courses, undergraduate research projects, and capstone experiences are among a list of high-impact educational practices compiled by George Kuh (2008), which measurably influence students’ success in areas such as student engagement and retention. It is recommended that all college students participate in at least two of these HIPs to deepen their approaches to learning, as well as to increase the transference of knowledge (Gonyea, Kinzie, Kuh, & Laird, 2008). In Mathematics, if a student participates in service-learning, it is typically in the form of tutoring, in conjunction with a school or with an after-school program, or modeling work or statistical analysis for non-profits. Today, I will discuss a number of service-learning projects developed for mathematics courses, which do not involve these traditional opportunities. I will also describe my current research project which has potential impact on my community and yours.

Abstract: Mathematicians love SET.

In this talk, we will discuss some of the mathematics connected to SET and then explore several new versions of the game, including one arising from projective geometry and one arising from non-abelian groups. In particular, we will see how these non-abelian variations on SET can give intuitive visualizations of abstract group structures.
