SUMMARY:Brain Imaging and Mathematical Modeling of Alzheimer's Disease (Peter Hinow\, U. Wisconsin\, Milwaukee)
DESCRIPTION:A wide variety of medical imaging methods exist for research and diagnostic procedures on the Central Nervous System (CNS)\, among them Magnetic Resonance Imaging (MRI) and Optical Imaging. Mathematical modeling and simulation contribute significantly to an improved understanding of image data and the intricate transport\, diffusion\, and metabolic processes in the brain. This is of particular importance in the study of pathologies such as Alzheimer’s Disease\, which\, 125 years after its description\, remains poorly understood and for which only moderate success has been made in its treatment. In the first work to be presented\, we investigate tracer diffusion and transport in the glymphatic system by combining optical imaging in rats with a partial differential equation of reaction-advection-diffusion type. In a second work\, we collect observations on the accumulation of amyloid-β\, changes in neuronal density\, and a decline in cognitive performance in TgF344-AD and wild-type rats. We develop a compartmental ordinary differential equation model and determine its parameters by fitting the output to the experimental observations. In the long run\, our mathematical modeling effort is intended to bridge AD research in rodent models and the human condition of AD. This is joint work with Dr. Muna Aryal (North Carolina Agricultural and Technical State University) and Micah Hesketh\, MS (graduate student\, UWM).

SUMMARY:From the basics of extremal graph theory to bipartite Turan numbers of trees and star forests (Omid Khormali\, HMC)
DESCRIPTION:Extremal graph theory asks how many edges a graph can have while avoiding a given substructure. We will begin with a brief\, accessible introduction to this area\, before turning to a natural variant\, the bipartite Turan number $(m\,n;H)$\, which restricts the host graph to be bipartite. This setting is especially natural when $H$ itself is bipartite\, such as a tree or star forest. We present new results determining the leading-order bipartite Turan number for trees and the exact bipartite Turan number for star forests\, along with a sketch of the key proof ideas.

SUMMARY:Claremont Topology Seminar: Helen Wong (CMC)
DESCRIPTION:Speaker: Helen Wong (CMC) \nTitle: Introduction to the colored Jones polynomial\n \nAbstract: This is a learning seminar. We will present an accessible definition of the colored Jones polynomial for knots and links and discuss the Volume Conjecture\, which relates the colored Jones polynomial of K with the volume of its complement S^3 \K. \n_______ \nWe especially welcome all undergraduates and graduate students to attend topology seminar! \nRoom: Roberts South 103

SUMMARY:CCMS Colloquium: Stable Khovanov Homology for Torus Links — Christine Lee (Texas State University)
DESCRIPTION:Abstract: Stable Khovanov homology \(Kh(T(n\, \infty))\) is an algebraic limit of the Khovanov homology groups of torus links \(T(n\, k) \) on a fixed number of strands \(n\)\, when more and more full twists are added as \(k \to \infty\). Stable Khovanov homology is intimately related to the Jones polynomial because it categorifies the Jones-Wenzl projector\, which can be used to define the colored Jones polynomial. \nWe still do not completely understand \(Kh(T(n\, \infty))\). The Gorsky-Oblomkov-Rasmussen conjecture predicts a simple form of the complex for which the explicit forms of the differentials are still open. I will talk about my summer research project with a group of undergraduate students where we use a process called “whittling” to compute explicit forms of the differentials for 3- and 4-stranded torus braids. We expect our results will serve as the base case for an induction proof of the GOR conjecture. \nBesides the discussion on providing meaningful research experience for undergraduate students\, the computational aspects of the project may be of interest to the audience. The students were organized into a “math” team and a “computer” team to encourage interaction of these perspectives in pursuit of a common goal. \n\n\n\nFor questions about the event\, please contact your CCMS Colloquium chairs: \nProf. Robert Cass (Robert.Cass@ClaremontMcKenna.edu) or Prof. Qidi Peng (Qidi.Peng@cgu.edu) \nFor logistical questions\, contact Maxwell Kooiker (Maxwell.Kooiker@cgu.edu)\, the CCMS Colloquium Assistant.

SUMMARY:GEMS October 3rd Session
DESCRIPTION:This GEMS session will be facilitated by Professor Chiu-Yen Kao from Claremont McKenna College. \nTitle: The Magic of 0s and 1s\n\nAbstract: Have you ever wondered how data in a computer is stored? In this talk\, we’ll crack open the binary numeral system\, the simple code of 0s and 1s that represents everything on your screen\, from text and audio to images and video. Through hands-on group activities (including encoding your own name in binary!)\, you’ll get to experience the magic of 0s and 1s for yourself. No background needed\, just curiosity!
