February 2019

Jeremie Palacci, Physics Department, UCSD – APS Colloquium

February 4, 2019 @ 4:00 pm - 5:00 pm

Title: Carving non-equilibrium pathways to control self-assembly Abstract: Active particles are microscopic particles, which can inject energy locally and made available by recent progress in colloidal science. They are ideal “pump-probes” to explore the emergent properties in non-equilibrium soft systems and control the behavior of soft matter and self-assembly at the microscale. In this talk, I will demonstrate how we can use dissipative building blocks to control self-assembly and show the robust formation of dynamical superstructures using active particles that consume fuel…

Peter Constantin, Princeton University – Brauer Lecture Day 1

May 1, 2019 @ 4:00 pm - 5:00 pm

Overall Title: "Fluid nonlinearity" Lecture I: Smooth and dissipative solutions of Euler equations, Navier-Stokes equations and the zero viscosity limit. Abstract: I will describe briefly basic questions of the area. Then I will discuss some of the recent results: 1) smooth multiscale solutions with compactly supported velocity and 2) conditions away from the boundary for the zero viscosity limit to be given by possibly dissipative solutions of Euler equations.     Biography: Dr. Peter Constantin, Princeton University, Princeton, NJ. Dr. Peter Constantin holds…

Peter Constantin, Princeton University – Brauer Lecture Day 2

May 2, 2019 @ 4:00 pm - 5:00 pm

Overall Title: “Fluid nonlinearity” Lecture II: Nernst-Planck-Navier-Stokes Equation Abstract: I will describe recent work concerning this system of equations describing ionic diffusion in fluids in the presence of boundaries with different kinds of properties.     Biography: Dr. Peter Constantin, Princeton University, Princeton, NJ. Dr. Peter Constantin holds degrees from the University of Bucharest, where he graduated "summa cum laude" in 1975, and from the Hebrew University of Jerusalem, where he received his PhD in 1981 with Professor Shmuel Agmon as his advisor. From…

Bao Wang – Faculty Interview Lecture

January 16, 2020 @ 4:00 pm - 5:00 pm

Tea and snacks available in Phillips Hall, Room 330 Title: PDE-Principled Trustworthy Deep Learning Meets Computational Biology Abstract: Deep learning achieves tremendous success in image and speech recognition and machine translation. However, deep learning is not trustworthy. 1. How to improve the robustness of deep neural networks? Deep neural networks are well known to be vulnerable to adversarial attacks. For instance, malicious attacks can fool the Tesla self-driving system by making a tiny change on the scene acquired by the intelligence system.…

Dongmian Zou – Faculty Interview Lecture

January 24, 2020 @ 4:00 pm - 5:00 pm

Title: Robust Representation for Graph Data Abstract: Modern data are usually high-dimensional with noise and corruption. A useful representation of data has to be robust and address the data structure. In this talk, I will first present a class of robust models called the scattering transform that can be used to generated features from graph data. In graph scattering transforms, the representation is generated in an unsupervised manner based on graph wavelets. It is approximately invariant to permutations and stable to signal…

Shahar Kovalsky – Faculty Interview Lecture

January 27, 2020 @ 4:00 pm - 5:00 pm

Title: Geometry + Optimization: towards computational anatomy Shahar Kovalsky Abstract: Geometric shape-processing lies at the heart of various branches of science: from finite element simulation in engineering, through animation of virtual avatars, to applications such as the analysis of anatomical variations, or detection of structural anomalies in medicine and biology. The demand for such computational approaches in geometry is constantly growing, as 3-dimensional data becomes readily available and is integrated into various everyday uses. I will begin my talk with…

Maria-Veronica Ciocanel – Faculty Interview Lecture

January 30, 2020 @ 4:00 pm - 5:00 pm

Title:Topological Data Analysis for Describing Ring Channel Dynamics Abstract:Contractile rings are structures made of actin filaments that are important in development, wound healing, and cell division. In many model organisms, ring channels allow nutrient exchange to developing egg cells and are regulated by forces exerted by myosin motor proteins. I will present an agent-based modeling and data analysis framework for the interactions between filaments and motor proteins inside cells. This approach may provide key insights for the mechanistic differences between…
