Abstract The talk will first introduce unimodular random graphs and give several examples from the theory of point processes, branching processes, random walks and self-similar discrete random sets. Several types of results on these graphs will then be …

Abstract Diffusion models can be used to synthesize samples with complex distributions and have many applications in data generation. Recently, they have been used as priors for solving Bayesian inverse problems. This presentation provides an overview of …

Abstract The interaction of light with matter is extremely rich. In chemistry and biology, the photon is used as a reagent in a wide range of preparative and analytical scientific developments. As this seminar will illustrate, however, the use of photons …

Abstract In the inter-war period, the universalist legacy of the Enlightenment was not confined to the colonialist discourse advocating Europe' s civilizing mission . It was used in other ways, from a European perspective, to defend democracy, oppose …

Writing as an underground temple where we crawl to consult an oracle in the darkness of the cave, the place of pre-writing. Become the pythia who enunciates an enigma to be submitted to the diviner who will decipher it. Past, present and future are …

Abstract The third lecture will discuss the Erdös-Ginzburg-Ziv Problem in discrete geometry, and show how (at least in high dimension) it can be reformulated as a problem in F_p^n. Specifically, this leads to the question of asking about the maximum …

Abstract From biocatalysts such as enzymes, to therapeutic targets and drugs such as membrane proteins and antibodies, various classes of proteins are manipulated outside their natural context. Stabilizing them is often a challenge. We will illustrate how …
