Tuesday, February 25th, 2025, 4:00pmLIT 225Talk with Dr. Sarah PollockAbstract
We will talk about some of the issues that arise in solving eigenvalue problems numerically, and introduce some recent ideas on how to address them. First we briefly demonstrate why we want to use methods different from how we first learn to solve eigenvalue problems by hand in linear algebra. Then we will talk about the power method, one of the most basic and powerful but sometimes very slow iterative methods. We will introduce momentum-type extrapolation methods which recycle older information in our approximation sequence to accelerate an iterative method. Finally, we will see that we can automate the algorithm!

Topic 1:
Image analysis and agent-based modeling of tumor-immune interactions in the glioblastoma microenvironment
Abstract 1:
Glioblastoma is a highly aggressive and deadly brain cancer with no current treatment options available that can achieve remission. One potential explanation for minimally effective treatments is the ability of gliomas to take advantage of processes within the body's immune system to infiltrate the tumor microenvironment with myeloid-derived suppressor cells (MDSCs). These cells hinder the ability of T cells to effectively destroy tumor cells. In this work, we create an agent-based model to simulate the interactions of these three cell types. Our model also includes three substrates to influence cell behavior: oxygen, a T cell chemoattractant, and an MDSC chemoattractant. To validate our model and quantify cell clustering patterns in glioblastoma, we use pair and cross-pair correlation functions (PCF and cross-PCF, respectively) on location data for each cell type. This data is extracted from cross-sectional tumor images of cellular biomarkers using image analysis techniques. We then conduct the same PCF and cross-PCF analysis on the cell location outputs from parameter testing trials of our ABM. These methods allow us to fit a linear model using the least squares method to the tumor image analysis results and evaluate how well the tests match the experimental data. From these results, we use our model to identify the impact of our tested parameters on cell clustering behavior within the glioblastoma tumor and its microenvironment.

Topic:
Astrophysical Turbulence
Abstract:
Turbulence is a ubiquitous phenomenon in both our daily life and in the universe, from our heliosphere to the interstellar medium of the Milky Way. It has a broad range of astrophysical applications, including star and planet formation, acceleration and propagation of energetic cosmic particles, and amplifying and dissipating magnetic fields. I will briefly discuss some basic properties of astrophysical turbulence, methods for its numerical modeling with the state-of-the-art simulations, its recent observations in the very local interstellar medium by the interstellar probes, Voyager 1 and Voyager2, and its application to a new mechanism of energetic particle transport in the universe.

Wednesday, April 12th, 2023, 4:00pmLittle Hall Atrium (3rd floor)Annual AWM Colloquium; Set Theory and the Powerset Function Dr. Dima Sinapova from Rutgers University, abstract:
Set theory is the study of the foundations of mathematics, and is rooted in analyzing properties of infinite sets. Historically, the first breakthrough was by Cantor, who proved that the cardinality of the real numbers is strictly bigger that the cardinality of the natural numbers. Namely, there is no bijection between them. More generally, any infinite set has strictly smaller cardinality than its powerset. After Cantor's theorem, the natural question emerged whether there is something in between. This became known as the Continuum Hypothesis (CH), which states that the answer is no: any infinite subset of the reals is either countable or there is a bijection between it and all the reals.

CH became Hilbert's First Problem. It was finally resolved by works of Godel (in 1940) and Cohen (in 1964) who showed that CH is independent of the usual mathematical axioms (ZFC). That means that neither CH, not its negation is a logical consequence of the ZFC axioms. Since Cohen's work, modern set theory investigates ZFC constraints (i.e. "what is necessary") versus consistency results (i.e. "what is possible"). We will survey these results and then focus on some recent developments in the study of infinite sets.
Wednesday, April 5th, 2023, 4:05pmLIT225Choose Your Own Adventure: The Non-traditional Route of a Computer Scientist; a talk by Dr. Sanethia ThomasAbstract:

Monday, April 3rd, 2023, 4:05pmLIT225Think Like a Hacker – An Introduction to Adversarial Thinking; a talk by Professor Resch Abstract:
What do you think of when you think of cybersecurity? Crypto algorithms? Firewalls? Passwords? You may think of technology when you think of cybersecurity, but cybersecurity is only necessary because of the existence of people who deliberately attack computer systems and networks. Often cybersecurity is defined by the CIA triad of confidentiality, integrity and availability. In this talk, we’ll learn about another triad: bounty, bad guys and barriers. At its heart, cybersecurity is an adversarial conflict between the bad guys who are trying to get their hands on the bounty and the good guys who are trying to protect the bounty. In order to practice cybersecurity effectively, one must pay careful attention to what computer hackers are thinking:
• What are their objectives?
• How might they go about achieving their objectives?
This mindset is known as adversarial thinking. Cybersecurity is about understanding technology, finding and fixing vulnerabilities, and anticipating future attacks. That third part is the most overlooked part of cybersecurity. In this talk we will look at anticipating future attacks through strategic thinking. We will look at elements of game theory as applied to cybersecurity, and do some exercises to demonstrate strategic thinking.

Wednesday, February 15th, 2023, 4:05pmLIT225Efficient Numerical Methods for Weak Solutions of Partial Differential Equations; a talk by Dr. WangAbstract:
Approximating weak solutions of partial differential equations (PDEs) is known to be important and extremely challenging in scientific computing and data science. In this talk, the speaker will discuss two kinds of numerical methods for weak solutions: (1) Primal-Dual Weak Galerkin (PDWG) finite element methods for low-dimensional PDEs; and (2) Deep Learning methods (Friedrichs Learning) for high-dimensional PDEs. The essential idea of PDWG is to interpret the numerical solutions as a constrained minimization of some functionals with constraints that mimic the weak formulation of the PDEs by using weak derivatives. The resulting Euler-Lagrange formulation results in a symmetric scheme involving both the primal variable and the dual variable (Lagrangian multiplier). Friedrichs Learning is a novel deep learning methodology that could learn the weak solutions of PDEs via a mini-max optimization characterization of the original problem. The speaker will explain what Friedrichs Learning is and how it can be used for solving PDEs with discontinuous solutions without any prior knowledge of the solution discontinuity.

Wednesday, October 26th, 2022, 4:00pm LIT225Multispectral Analysis and Deep Learning for Life Science and Biomedical Research; a talk by Dr. Corey Toler-FranklinAbstract:
In this talk, I will present an overview of my recent work developing multispectral analysis algorithms, and deep learning models for application in life science and biomedical research. Several plant and animal species are more comprehensively understood by multispectral analysis. However, traditional non-photorealistic illustrative techniques ignore unique information outside the visible spectrum. I will present new rendering techniques that use near-infrared and ultraviolet spectra to visualize layered materials found in biological specimens. I will then discuss a texture transfer framework that extends this work to reconstruct invisible (or faded) appearance properties in organic materials with complex color patterns. Key contributions include a novel ultraviolet illumination system that records changing material property distributions, and a color reconstruction algorithm that uses spherical harmonics and principles from chemistry and biology to learn relationships between color (hue and saturation) and material composition and concentration in an exemplar. Finally, I will explain a novel algorithm that extends the effective receptive field of a convolutional neural network for multi-scale detection of cancerous tumors in high resolution slide scans. The results permit efficient real-time analysis of medical images in pathology and related biomedical research fields.

Wednesday, October 19th, 2022, 4:00pmLIT225Cyber-physical System Security; a talk by Dr. Sara RampazziAbstract:
Rampazzi's lab research core is cyber-physical system security and privacy. By exploiting sensors and electronic components' flaws, attackers can get the upper hand against even the most carefully designed system. Attack results range from extracting sensitive information by observing unintentional emissions through physical parameters (e.g., electromagnetic radiation), to undermining the system's capacity to acquire correctly, process, and interpret external stimuli. For instance, injecting inaudible signals using light through microphones, can induce voice-controlled smart devices into executing unauthorized commands while providing false inputs to LiDARs, and cameras can induce vehicles to perceive non-existent obstacles.
This talk will present some examples of the research conducted by prof. Sara Rampazzi's Lab team, and hints on how to design better and safe cyber-physical systems.
Wednesday, October 5th, 2022, 4:00pmLIT225My Work and the Things That Move Me; a talk by professor Carol DemasAbstract:

Wednesday, September 21st, 2022, 4:00pmLIT225Using Mathematics to Understand the Growth and Treatment of Cancer; a talk by Dr. Tracy Stepien Abstract:
More than 1.9 million new cancer cases are expected to be diagnosed in 2022 in the U.S. according to the American Cancer Society. While treatment is generally successful for some types of cancer, there are many types of cancer where the survival rate is very low after diagnosis. Alongside clinical and experimental studies, researchers are turning to mathematical modeling to try to elucidate how cancer starts and spreads, and how we can treat it. In this talk, I will discuss the fundamental mathematics of tumor growth and then model the growth and treatment of glioblastoma multiforme, an aggressive brain cancer that is extremely fatal.

Friday, February 11th, 2022, 4:00pmZoomUsing Mathematics to Predict Which Cancer Patients Will Respond to Immunotherapy; a talk by Dr. Helen MooreAbstract:
Immunotherapies don't work for most cancer patients; but when they do work, they can work extremely well. So it is important to figure out as early as possible if a patient will be a "responder" or a "non-responder". I will present a simple mathematical model for patient tumor sizes. I combined the model parameters with machine learning to create an early predictor of response/non-response. I will show how I validated the predictor on data sets for different cancer types and immunotherapies.
