@article{8539, abstract = {Cohomological and K-theoretic stable bases originated from the study of quantum cohomology and quantum K-theory. Restriction formula for cohomological stable bases played an important role in computing the quantum connection of cotangent bundle of partial flag varieties. In this paper we study the K-theoretic stable bases of cotangent bundles of flag varieties. We describe these bases in terms of the action of the affine Hecke algebra and the twisted group algebra of KostantKumar. Using this algebraic description and the method of root polynomials, we give a restriction formula of the stable bases. We apply it to obtain the restriction formula for partial flag varieties. We also build a relation between the stable basis and the Casselman basis in the principal series representations of the Langlands dual group. As an application, we give a closed formula for the transition matrix between Casselman basis and the characteristic functions.}, author = {Su, C. and Zhao, Gufang and Zhong, C.}, issn = {0012-9593}, journal = {Annales Scientifiques de l'Ecole Normale Superieure}, number = {3}, pages = {663--671}, publisher = {Société Mathématique de France}, title = {{On the K-theory stable bases of the springer resolution}}, doi = {10.24033/asens.2431}, volume = {53}, year = {2020}, } @inbook{14000, abstract = {This chapter presents an overview of the state of the art in attosecond time-resolved spectroscopy. The theoretical foundations of strong-field light–matter interaction and attosecond pulse generation are described. The enabling laser technologies are reviewed from chirped-pulse amplification and carrier-envelope-phase stabilization to the generation and characterization of attosecond pulses. The applications of attosecond pulses and pulse trains in electron- or ion-imaging experiments are presented, followed by attosecond electron spectroscopy in larger molecules. After this, high-harmonic spectroscopy and its applications to probing charge migration on attosecond time scales is reviewed. The rapidly evolving field of molecular photoionization delays is discussed. Finally, the applications of attosecond transient absorption to probing molecular dynamics are presented.}, author = {Baykusheva, Denitsa Rangelova and Wörner, Hans Jakob}, booktitle = {Molecular Spectroscopy and Quantum Dynamics}, editor = {Marquardt, Roberto and Quack, Martin}, isbn = {9780128172353}, pages = {113--161}, publisher = {Elsevier}, title = {{Attosecond Molecular Dynamics and Spectroscopy}}, doi = {10.1016/b978-0-12-817234-6.00009-x}, year = {2020}, } @misc{13056, abstract = {This datasets comprises all data shown in plots of the submitted article "Converting microwave and telecom photons with a silicon photonic nanomechanical interface".

However, due to its toxicity, cells have developed elaborate mechanisms for Cu homeostasis, which balance Cu supply for cuproprotein biogenesis with the need to remove excess Cu. This review summarizes our current knowledge on bacterial Cu homeostasis with a focus on Gram-negative bacteria and describes the multiple strategies that bacteria use for uptake, storage and export of Cu. We furthermore describe general mechanistic principles that aid the bacterial response to toxic Cu concentrations and illustrate dedicated Cu relay systems that facilitate Cu delivery for cuproenzyme biogenesis. Progress in understanding how bacteria avoid Cu poisoning while maintaining a certain Cu quota for cell proliferation is of particular importance for microbial pathogens because Cu is utilized by the host immune system for attenuating pathogen survival in host cells.}, author = {Andrei, Andreea and Öztürk, Yavuz and Khalfaoui-Hassani, Bahia and Rauch, Juna and Marckmann, Dorian and Trasnea, Petru Iulian and Daldal, Fevzi and Koch, Hans-Georg}, issn = {20770375}, journal = {Membranes}, number = {9}, publisher = {MDPI}, title = {{Cu homeostasis in bacteria: The ins and outs}}, doi = {10.3390/membranes10090242}, volume = {10}, year = {2020}, } @article{8581, abstract = {The majority of adenosine triphosphate (ATP) powering cellular processes in eukaryotes is produced by the mitochondrial F1Fo ATP synthase. Here, we present the atomic models of the membrane Fo domain and the entire mammalian (ovine) F1Fo, determined by cryo-electron microscopy. Subunits in the membrane domain are arranged in the ‘proton translocation cluster’ attached to the c-ring and a more distant ‘hook apparatus’ holding subunit e. Unexpectedly, this subunit is anchored to a lipid ‘plug’ capping the c-ring. We present a detailed proton translocation pathway in mammalian Fo and key inter-monomer contacts in F1Fo multimers. Cryo-EM maps of F1Fo exposed to calcium reveal a retracted subunit e and a disassembled c-ring, suggesting permeability transition pore opening. We propose a model for the permeability transition pore opening, whereby subunit e pulls the lipid plug out of the c-ring.
