We present a direct imaging algorithm for both the location and geometry of extended targets. Our algorithm is based on a physical factorization of the response matrix of an active array. A resolution and noise level based thresholding is used for regularization. Our algorithm is extremely simple and efficient since no forward solver or iteratio...

I will present a direct constrained minimization (DCM) algorithmfor solving the Kohn-Sham equations. The key ingredients of thisalgorithm involve projecting the Kohn-Sham total energy functionalinto a sequences of subspaces of small dimensions and seeking theminimizer of total energy functional within each subspace. Theminimizer of a subspace en...

Joint work with Chunyan Huang, Christoph Schwab and GerritWelper.The success of adaptive (wavelet) methods for operator equations relies on well-posedness ofsuitable variational formulations and on theavailability of Riesz bases (or frames) for the corresponding energy space provided thatthe corresponding representation of the operator is in a c...

Trigger Warnings: A Generative Dialogue. Trigger warnings are designed to prevent unaware encounters with topics that might elicit strong and damaging emotional responses in some people. Some call them a bandaid; others raise issues of academic freedom. This discussion will focus on how we can reframe and move beyond these debates to address how...
We consider a system of hyperbolic-parabolic equations describinga material instability mechanism associated to the formation ofshear bands at high strain-rate plastic deformations of metals. We consider the case of adiabatic shearing and derive a quantitative criterion for the onset of instability: Using ideas from the theory of relaxation syst...

Adiabatic perturbation theory is a general scheme that allows for the mathematically rigorous derivationof effective equations in quantum mechanical slow-fast systems. In this lecture I explain how to justify andcompute corrections to the time-dependent Born-Oppenheimer approximation. In the second part I presentsome recent results (jointly with...

In many physical systems it is believed that one can describe parts of the system by classical and parts of the system by quantum mechanics.In this lecture I explain how to rigorously derive such effective 'mixed quantum-classical' descriptions from the underlying quantum mechanicsfor the whole system. The important mechanism is adiabatic decoup...

We have applied new experimental and computational approaches to understand the mechanical events of adherent cells. While the extensive use of flexible substrates has lead to excellent understanding of traction forces, introduction of long polymers into the cytoplasm has started to shed light on weak gradients of forces generated by the cortex....
