Title: How Interest Rates Affect Wealth and Consumption: A Control-Theory Perspective

Abstract: This project investigates how the Federal Reserve's interest rate policy can be used to influence household wealth and consumption within a dynamic system. The economy is modeled as a control system, where household behavior is described by a set of differential equations. The Fed acts as a controller, using the interest rate to guide the system toward a "target zone" where both wealth and consumption are sustainable. 

Speaker(s): Sally Brouhard, Jacob Martin, Beckett Rebele-Henry, Sammie Ritchie, Dan Schwartz, and Pepe Sanchez-Menchen—Jim Davis, Mentor

Title: Construction of Generalized Denniston Partial Difference Sets

Abstract: Partial difference sets are used to construct error correcting codes with efficient encoding and decoding algorithms. Our team worked on constructing new partial difference sets in groups that are not elementary abelian. We will describe what we mean by a partial difference set, and we will outline how we were able to construct some new examples.

Speaker(s): Gabby Singer, Chen Peng, Rachel Tan, Marelin Lopez Gregorio, Jonathan Zhang, Yudong Liang

Title: Developing a Virtual Tissue Model of Airway Remodeling in Response to Inhaled Toxicants 

Abstract: Airway remodeling caused by inhaled toxicants like wood smoke involves complex interactions between immune cells, epithelial damage, and tissue restructuring that leads to fibrosis and respiratory disease. Our team began the development of a hybrid computational model combining ordinary differential equations with spatial cellular automata to simulate these biological processes. We will describe how biological hypotheses can be translated to network models and represented with spatial cell behavior modeling in CompuCell3D, and we will present some of our experimental validation.
