Title: DYNAMIC AND CONTROL OF AUTOIMMUNE DISORDER UNDER RADIATION

Abstract:  Autoimmune diseases can be developed by exposure to radiation. Ionizing radiation modifies the immune system and diminishing its normal ability to fight diseases.  The extents of the modifications depend on the dose rate and duration of radiation exposure.  This work employs mathematical simulations of autoimmune process dynamics under irradiation. The mathematical model employed in this work consists of four non-linear differential equations.  The variables used in the modeling are the concentration of target cells of the tissue, concentration of cytotoxic T-lymphocytes, the concentration of tissue-specific antigen, and the concentration of T-suppressor cortical thymus.

Speaker: Dr. Christopher Tralie, Ursinus College
Title: TDALabs: (Some of) TDA's Greatest Hits in Interactive Python
Abstract: Abstract: TDA software is becoming more mainstream and accessible to both mathematicians in the field and to data scientists at large. Recently, I worked as part of a small team of open source software developers to create a Python library known as scikit-tda (https://scikit-tda.org/). In addition to using this library in myriad research applications, I have also been developing a compendium of examples for pedagogical purposes, some of which are in a repository I call "TDALabs" (https://github.com/ctralie/TDALabs). In this talk, I will interactively go through a number of these examples, including a demo of the stability theorem, sliding windows in time series and video, the natural space of image patches, diffusion maps and TDA, lower star image filtrations for cell segmentation in images, mesh reconstruction via alpha shapes, and isometry blind 3D shape clustering. It is the hope that people will be inspired to use these materials in their own courses and workshops, and it is also the hope that some will help me build on them and contribute additional concise examples that showcase their work. Pull requests are welcome!

Title: Collision dynamics in some gravitational N-body problems
Abstract: The equations of motion for gravitating bodies have singularities when any two of the bodies occupy the same point in space, i.e. when there is a collision.  It is well known, but still quite interesting, that one can make sense of orbits that ``go through'' collisions by a process called regularization.  I'll introduce the idea of regularization and illustrate its use in some numerical calculations

Algebra Seminar with Dr. Zvi Rose, Department of Mathematical Sciences, Florida Atlantic University

Title: Oriented Matroids and Combinatorial Neural Codes.
Abstract: A combinatorial neural code is convex if it arises as the intersection pattern of convex open subsets of Euclidean space. We relate the emerging theory of convex neural codes to the established theory of oriented matroids, in both a category-theoretic sense and with respect to feasibility and complexity. By way of this connection, we prove that all convex codes are related to some representable oriented matroid, and we show that deciding whether a neural code is convex is NP-hard.

Title: An Introduction to Quantum Key Distribution
Abstract: Quantum mechanics was one of the greatest scientific breakthroughs of the last century with applications still being found.  Since the 1970’s mathematicians and physicists have been exploring how quantum mechanics can be used in cryptography to achieve previously thought impossible results.  In this talk, we will give an overview of the problem of key establishment and how quantum phenomena can be used to achieve secure key establishment

Title: Combinatorial Game Theory
Abstract: This will be a talk which begins with the game of Nim and Sprague-Grundy numbers. We will then discuss a few newer games and some recent results.  The level of the talk should be suitable for graduate students and even some interested undergraduates.

Master's Presentation with Melissa De Jesus

Title: Stability Analysis of the SIR model
Abstract:  The SIR model is one way that we can analyze how the spread of a disease effects a population overtime.  In this model, the spread of a disease divides our population into 3 non-intersecting classes: susceptible, infected, and recovered.  By studying the dynamics of this system, we are able to predict how the disease will behave in the population. We are interested in the stability of the equilibria points which will help us decide whether a disease will die out, or if it will stabilize itself.

FAU's Student Chapter of the AWM Care To BEE Event

Dr. Nina Fefferman will be joining us live on Webex for a problem-solving session based on topics from a pre-recorded webinar from NIMBioS,  "The Role of Applied Math in Real-time Pandemic Response How Basic Disease Models Work"

Dr. Nina Fefferman is a mathematical biologist with a long history of work on biosecurity and pandemic preparedness and response. She has consulted in this area for state and federal agencies and departments on threats including TB, Ebola, Zika virus, H1N1 2009, and many others, now including COVID-19. She is a professor in the Departments of Mathematics and Ecology & Evolutionary Biology at the University of Tennessee, Knoxville. Dr. Fefferman directs the Mathematical Modeling Center at the National Institute for Mathematical and Biological Synthesis.

Abstract: It's not normally instantly obvious what mathematicians do. It's also not normal to be able to use middle-school math to help try to save the world. Right now, things are not normal. Join us for "The role of applied math in real-time pandemic response: How basic disease models work" for a presentation about how very simple, middle-school math (and much fancier versions of the same thing) can help us fight COVID-19.

Be sure to register online. This conference is open to anyone interested in mathematics at FAU and neighboring institutions! Please sign up so that we can contact you with relevant information. Also, if you would like to provide a mailing address, we will be sending out promotional items (note this is optional). 

This initiative was made possible by the generous support of Lisa Simonyi, the IAS Women and Mathematics Program, and the FAU Department of Mathematical Sciences.
