Seminar 1

"Controlling and Sensing Spin Systems with Free Space Electrons" by Prof. Philipp Haslinger, Vienna University of Technology

Seminar 2

"Electron-Photon Entanglement in Electron Microscopy" by Mr. Alexander Preimesberger, Vienna University of Technology

Speaker: Professor Alexander Menovschikov, HSE University Title: Nonlinear Neumann Eigenvalues in Outward Cuspidal Domains With Weighted Measure Abstract:

We consider the nonlinear Neumann eigenvalue problem in outward cuspidal domains with a weighted measure. Using composition operators on Sobolev spaces, we establish embeddings of Sobolev spaces into weighted Lebesgue spaces. These embeddings give the solvability of the Neumann spectral problem in this setting and provide estimates for the corresponding weighted Neumann eigenvalues

Speaker: Huy Truong, Kansas State University Title: Base Modulus for Matroid Truncation, Strength, and Fractional Arboricity Abstract:

In previous work, we studied the -modulus of the family of all bases of a matroid and showed that it recovers several classical concepts in matroid theory, including strength, fractional arboricity, and principal partitions. These results generalize corresponding concepts for spanning trees in graphs. Due to computational constraints, one may impose a bound on the number of elements sampled from a base. For instance, when exploring a tree, we may stop at forests with edges. Such objects are captured by matroid truncations. In this paper, we study the modulus of matroid truncations and determine the universal density for every truncation of a given matroid. As a consequence, we show that the truncation modulus serves as an approximation of the original matroid modulus.

Speaker: Professor Alexander Menovschikov, HSE University Title: On Mappings Generating Embedding Operators in Sobolev Classes on Metric Measure Spaces Abstract:

Let X =(X,ρ,µ) be a doubling metric measure space which supports the weak p-Poincar´e inequality. We consider bi-measurable homeomorphisms φ : Ω → Ω, of bounded domains Ω, Ω ⊂ X, which generate bounded composition operators on Newtonian–Sobolev spaces N1,p(Ω) → N1,q(Ω),1 < q ≤ p < ∞. We prove the Luzin N−1-property of such mappings with respect to capacities and obtain necessary and sufficient conditions on bi-measurable homeomorphisms that generate bounded composition operators on Newtonian–Sobolev spaces. We prove this by using special test functions generated by distance functions. On the base of the composition operators we consider Sobolev type embedding theorems in weak (p,q)-quasiconformal α-regular domains

In collaboration with leading venture capital firms, OIST Innovation offers startups and entrepreneurial researchers or students the opportunity to connect directly with venture capitalists for one-on-one mentoring and discussion. Each round begins with an open seminar-style introduction, where participants can learn about the VC firm's investment focus and characteristics. This is followed by private, closed-door mentoring sessions between startups/researchers/students and the VC representatives.

The featured VC for this round is Intrinsic Venture Capital .

This training course will show you how to make best use of the high-performance computing resources at OIST. In the first session we show you how computing clusters are organized and introduce the fundamental concepts of parallel computing.

Speaker: Professor Chun-Chi Lin, National Taiwan Normal University Title: The p-elastic flows of inextensible planar closed curves for p ∈ (1, ∞) Abstract:

Building on the work of Blatt, Hopper, and Vorderobermeier (2022) on the existence of geometric flows for the p-elastic energy with p∈ [2,∞), we investigate how to extend their results to the case p∈(1,2). In this talk, we focus on the class of inextensible planar closed curves. We establish the existence of global weak solutions to the L 2 -gradient flow of the p-elastic energy for all p ∈ (1, ∞). Further directions, including extensions to open curves and applications to variational problems of curves in sub-Riemannian geometry, will also be discussed. The results presented are based on joint work with Ying-Hsian Tsai.

Biophysical Principles of Regulation in Bacteria including quantitative models, regulatory adaptations, replication control, and gene regulation through gene promoters. Presented by Dr Alberto Sassi, a post-doc in the Pigolotti Unit.

Abstract : Hybrid-pixel detectors have revolutionized electron microscopy by combining direct detection with noise-free readout and single-electron sensitivity. This technology enables ultrafast 4D STEM at 120,000 frames per second and high-resolution EELS, allowing for the visualization of beam-sensitive materials and complex magnetic domains. By integrating high dynamic range with radiation-hard designs, Hybrid-pixel detectors bridge the gap between traditional imaging and advanced diffraction analysis to empower breakthroughs in materials science and structural biology.
