    We study a new direction of research in "property testing": Permutation equations.
    Let A and B be two permutations in Sym(n) that "almost commute"- are they a small deformation of permutations that truly commute?
    More generally, if R is a system of word-equations in variables X=x_1,....,x_d and A_1,....,A_d are permutations which are almost a solution

    Although open-access databases are an important resource in the current deep learning (DL) era, they are sometimes used in an "off label" manner: data published for one task are used during training of algorithms for a different task. In this seminar I will show that this leads to biased, overly optimistic results of well-known inverse problem solvers, focusing on algorithms developed for magnetic resonance imaging (MRI) reconstruction. I will show that when such algorithms are trained using off-label data, they yield biased results, with up to 48% artificial improvement. The underlying cause is that public databases are often preprocessed using hidden pipelines, which change the data features and improve the inverse problem conditioning. My work shows that canonical algorithms - Compressed Sensing, Dictionary Learning, and Deep Learning algorithms - are all prone to this form of bias. Furthermore, once trained, these algorithms exhibit poor generalization to real-world data, thus they could produce unreliable results in clinical setups. To raise awareness to the growing problem of naive use of public data and the associated biased results, the term "data crimes" is coined.

    In the present seminar, I will introduce how the flat bands in the magic angle twisted bilayer graphene (MATBG) can be understood from the zeroth Landau levels under the twisting generated pseudo magnetic field. These pseudo Landau level wave functions are almost the exact Eigen solutions of the real space Hamiltonian around the AA stacking center and can be further viewed as the analog of the “atomic core level” states in the band structure calculations for the ordinary crystals. In addition, we can use the pseudo zeroth Landau level (PZLL) and the “orthogonalised plane waves” (OPW) made from the PZLL as the two types of basis functions to efficiently reconstruct the entire Moire band structure. Using these PZLL and OPW basis functions, we can describe both the localised and itinerant components in the Moire bands of MATBG and map the MATBG to a “heavy fermion” like system, which can be used to study the orbital magnetism, topology and strongly correlation physics in MATBG.

    Graphene is intensively explored in last decades. This unique material exhibit several possibilities for chemical modifications in order to control its physical and chemical properties. Introduction of various chemical functionalities will be discussed. Beyond graphene the other related materials remain almost unexplored. The research activities in the field of other layered materials like phosphorene, arsenene, silicene and germanene are rapidly growing in the last few years. Compare to graphene, all these materials are non-zero band-gap semiconductors. This property opens new application possibilities in electronic and optoelectronic devices. The properties of 2D materials can be further controlled by their functionalization. The chemistry of materials beyond graphene is none explored and shows high application potential in many fields. Compare to the graphene and pnictogen group, the chemical exfoliation method mast be applied for synthesis of silicene / germanene derivatives using Zintl phase compounds like CaGe2 and CaSi2. Various methods well know from organic chemistry can be applied for synthesis of tetrel derivatives reaching almost complete derivatization of 2D material skeleton. Beside also other 2D compounds synthesis and chemistry will be discussed covering layered chalcogenides, halides and others.

    Using mammalian skin as a model, Prof. Elaine Fuchs studies the remarkable properties
    of tissue stem cells to replenish dying cells and repair wounds, and how the cells know
    which tasks to perform and when. She explores how stem cells sense and communicate
    with other cells in their environment. Aiming at advancing therapeutics, she dissects how
    communication networks malfunction in inflammation, aging, and cancers.
