Dr. Olivia Walch, the CEO of Arcascope, From simulations to subscriptions: Putting research math biology into the App Store

Zoom

In this talk, Dr. Olivia Walch, the CEO of Arcascope, will discuss her research into the mathematics of sleep and circadian rhythms modeling, and large scale analysis of wearable data. She will also discuss her journey from being a post-doc to forming her own start-up, as well as the challenges and opportunities in taking these mathematical…

Daniel Massatt, University of Chicago, Electronics of Relaxed Bilayer 2D Heterostructures in Momentum Space

Zoom

Incommensurate stacked 2D materials have gained significant attention after the recent discovery of a new mechanism of superconductivity in systems with small twist angles. Theoretically, the electronics of such systems are studied through tight-binding models. These models can be studied in several different spaces, though momentum space is often the leading favorite for physicists because…

David Wiygul, ETH Zurich, Mass estimates for static vacuum metrics with small Bartnik data

Zoom

In general relativity, in the absence of special symmetries, there is no reasonable, nontrivial notion of mass-energy density accounting not only for all source fields but also for gravity itself. Nevertheless there are good definitions, such as the ADM mass, of the mass of an entire isolated system, modelled as an asymptotically flat space-time. Numerous…

Radu Ioan Boţ, University of Vienna Oskar-Morgenstern-Platz 1, Austria, Primal-dual dynamical approaches to structured convex minimization problems

Zoom

In this talk, we first propose a primal-dual dynamical approach to the minimization of a structured convex function consisting of a smooth term, a nonsmooth term, and the composition of another nonsmooth term with a linear continuous operator. To this end we introduce a dynamical system for which we prove that its trajectories asymptotically converge…

What are PTP and TCC?

Zoom

Are you interested in continuing in academia after you finish your degree?  You should consider the Preparing the Professoriate program and/or the Teaching and Communications Certificate offered by NCSU!  This week in the Graduate Training Module, GIST is excited to host Vanessa Doriott Anderson, Director of the Teaching and Communication Programs and Organizer of the Preparing…

Learning LaTeX Tutorial

Zoom

Are you an undergraduate that has heard of LaTeX, but don't know how to use it?  This event is for you!  LaTeX is the typesetting software used by the majority of mathematicians (and several other fields) for everything from CV's, to research papers to exams.  If you plan on continuing in academia, it is almost necessary…

AMS/MGSA Trivia Night

Zoom

The AMS Student Chapter and MGSA are co-hosting a Trivia Night for graduate students on Friday, October 29, 5-6:30pm. Free pizza, chips, and soda will be provided in the 4th floor lounge. We'll form teams based on MentoRings as possible, though you do not need to be in a MentoRing (or have a team already formed)…

Ailana Fraser, University of British Columbia, Geometries That Optimize Eigenvalues

Zoom

When we choose a metric on a manifold we determine the spectrum of the Laplace operator. Thus an eigenvalue may be considered as a functional on the space of metrics. For example the first eigenvalue would be the fundamental vibrational frequency. In some cases the normalized eigenvalues are bounded independent of the metric. In such cases…

Dave Shirokoff, New Jersey Institute of Technology, Implicit-Explicit (IMEX) Stability and Applications to the Dispersive Shallow Water Equations

Zoom

In this talk we will introduce a new stability theory for implicit-explicit (IMEX) time integration schemes—which treat some terms in a differential equation implicitly (for stability) and others explicitly (for efficiency).  Our focus will be on devising new efficient stable schemes for several fluid equations ranging from the incompressible Navier-Stokes equations, nonlinear diffusion equations, and…

Peter Olver, University of Minnesota Reconstruction and signatures of 3D bodies

Zoom

The talk will begin with the reconstruction of three-dimensional bodies from their two-dimensional projections.  Then I analyze the induced action of the Euclidean group on the body's projected outlines using moving frames, leading to a complete classification of the outline differential invariants and the associated outline signature of the body.   Zoom invitation is sent…

Gregory Forest, UNC Chapel Hill, Modeling Insights Into SARS-CoV-2 Respiratory Tract Infections

Zoom

I and many collaborators, postdocs, and students from many disciplines have explored lung mechanics and disease pathology for over 2 decades in a pan-university effort called the UNC Virtual Lung Project. In the last decade we have explored how viruses “traffic” in mucosal barriers, including the human respiratory tract (RT), in the presence of antibodies.…
