[{"issue":"42","publication":"Langmuir","abstract":[{"text":"Azobenzenealkanethiols in self-assembled monolayers (SAMs) on Au(111) exhibit reversible trans–cis photoisomerization when diluted with alkanethiol spacers. Using these mixed SAMs, we show switching of the linear optical and second-harmonic response. The effective switching of these surface optical properties relies on a reasonably large cross section and a high photoisomerization yield as well as a long lifetime of the metastable cis isomer. We quantified the switching process by X-ray absorption spectroscopy. The cross sections for the trans–cis and cis–trans photoisomerization with 365 and 455 nm light, respectively, are 1 order of magnitude smaller than in solution. In vacuum, the 365 nm photostationary state comprises 50–74% of the molecules in the cis form, limited by their rapid thermal isomerization back to the trans state. In contrast, the 455 nm photostationary state contains nearly 100% trans-azobenzene. We determined time constants for the thermal cis–trans isomerization of only a few minutes in vacuum and in a dry nitrogen atmosphere but of more than 1 day in ambient air. Our results suggest that adventitious water adsorbed on the surface of the SAM stabilizes the polar cis configuration of azobenzene under ambient conditions. The back reaction rate constants differing by 2 orders of magnitude underline the huge influence of the environment and, accordingly, its importance when comparing various experiments.","lang":"eng"}],"day":"25","oa_version":"None","extern":"1","publication_status":"published","scopus_import":"1","title":"Differing isomerization kinetics of azobenzene-functionalized self-assembled monolayers in ambient air and in vacuum","author":[{"full_name":"Moldt, Thomas","last_name":"Moldt","first_name":"Thomas"},{"first_name":"Daniel","full_name":"Przyrembel, Daniel","last_name":"Przyrembel"},{"first_name":"Michael","full_name":"Schulze, Michael","last_name":"Schulze"},{"last_name":"Bronsch","full_name":"Bronsch, Wibke","first_name":"Wibke"},{"full_name":"Boie, Larissa","last_name":"Boie","first_name":"Larissa"},{"first_name":"Daniel","last_name":"Brete","full_name":"Brete, Daniel"},{"full_name":"Gahl, Cornelius","last_name":"Gahl","first_name":"Cornelius"},{"full_name":"Klajn, Rafal","last_name":"Klajn","first_name":"Rafal","id":"8e84690e-1e48-11ed-a02b-a1e6fb8bb53b"},{"full_name":"Tegeder, Petra","last_name":"Tegeder","first_name":"Petra"},{"last_name":"Weinelt","first_name":"Martin","full_name":"Weinelt, Martin"}],"external_id":{"pmid":["27681851"]},"article_type":"original","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"13386","page":"10795-10801","pmid":1,"year":"2016","doi":"10.1021/acs.langmuir.6b01690","date_updated":"2023-08-07T12:27:06Z","publisher":"American Chemical Society","keyword":["Electrochemistry","Spectroscopy","Surfaces and Interfaces","Condensed Matter Physics","General Materials Science"],"type":"journal_article","status":"public","intvolume":" 32","volume":32,"article_processing_charge":"No","month":"10","citation":{"ista":"Moldt T, Przyrembel D, Schulze M, Bronsch W, Boie L, Brete D, Gahl C, Klajn R, Tegeder P, Weinelt M. 2016.

Furthermore, we construct strategies for Player 1 that use space s(T), for an arbitrary small unbounded non-decreasing function s, and which guarantee an ε-optimal value for Player 1 in the limit superior sense. The previously known strategies use space Ω(log T) and it was known that no strategy can use constant space if it is ε-optimal even in the limit superior sense. We also give a complementary lower bound. Furthermore, we also show that no Markov strategy, even extended with finite memory, can ensure value greater than 0 in the Big Match, answering a question posed by Neyman [11]."}],"day":"01","project":[{"grant_number":"S 11407_N23","call_identifier":"FWF","name":"Rigorous Systems Engineering","_id":"25832EC2-B435-11E9-9278-68D0E5697425"},{"_id":"25892FC0-B435-11E9-9278-68D0E5697425","name":"Efficient Algorithms for Computer Aided Verification","grant_number":"ICT15-003"},{"_id":"2581B60A-B435-11E9-9278-68D0E5697425","name":"Quantitative Graph Games: Theory and Applications","call_identifier":"FP7","grant_number":"279307"}],"scopus_import":"1","publication_status":"published","alternative_title":["LNCS"],"date_published":"2016-09-01T00:00:00Z","citation":{"mla":"Hansen, Kristoffer, et al.

The hormone auxin is redistributed in stimulated organs leading to differential growth and bending. Auxin application triggers rapid cell wall acidification and elongation of aerial organs of plants, but the molecular players mediating these effects are still controversial. Here we use genetically-encoded pH and auxin signaling sensors, pharmacological and genetic manipulations available for Arabidopsis etiolated hypocotyls to clarify how auxin is perceived and the downstream growth executed. We show that auxin-induced acidification occurs by local activation of H+-ATPases, which in the context of gravity response is restricted to the lower organ side. This auxin-stimulated acidification and growth require TIR1/AFB-Aux/IAA nuclear auxin perception. In addition, auxin-induced gene transcription and specifically SAUR proteins are crucial downstream mediators of this growth. Our study provides strong experimental support for the acid growth theory and clarified the contribution of the upstream auxin perception mechanisms.","lang":"eng"}],"ddc":["581"],"project":[{"_id":"25681D80-B435-11E9-9278-68D0E5697425","name":"International IST Postdoc Fellowship Programme","call_identifier":"FP7","grant_number":"291734"},{"_id":"25716A02-B435-11E9-9278-68D0E5697425","name":"Polarity and subcellular dynamics in plants","call_identifier":"FP7","grant_number":"282300"}],"publication":"eLife","oa_version":"Published Version","ec_funded":1,"has_accepted_license":"1","pubrep_id":"654","article_number":"e19048","scopus_import":"1","corr_author":"1","publication_status":"published"},{"external_id":{"isi":["000380346500013"]},"author":[{"first_name":"Gergely","full_name":"Molnar, Gergely","id":"34F1AF46-F248-11E8-B48F-1D18A9856A87","last_name":"Molnar"},{"first_name":"Matyas","full_name":"Fendrych, Matyas","id":"43905548-F248-11E8-B48F-1D18A9856A87","last_name":"Fendrych","orcid":"0000-0002-9767-8699"},{"last_name":"Friml","first_name":"Jirí","id":"4159519E-F248-11E8-B48F-1D18A9856A87","full_name":"Friml, Jirí","orcid":"0000-0002-8302-7596"}],"title":"Plasma membrane: Negative attraction","department":[{"_id":"JiFr"}],"file":[{"file_name":"IST-2018-1007-v1+1_Molnar_NatPlants_2016.pdf","access_level":"open_access","relation":"main_file","date_updated":"2020-07-14T12:44:45Z","date_created":"2018-12-12T10:12:36Z","file_id":"4954","checksum":"9ba65f558563b287f875f48fa9f30fb2","creator":"system","file_size":127781,"content_type":"application/pdf"},{"access_level":"open_access","date_updated":"2020-07-14T12:44:45Z","relation":"main_file","date_created":"2018-12-12T10:12:37Z","checksum":"550d252be808d8ca2b43e83dddb4212f","file_id":"4955","creator":"system","file_name":"IST-2018-1007-v1+2_Molnar_NatPlants_2016_editor_statement.pdf","file_size":430556,"content_type":"application/pdf"}],"scopus_import":"1","corr_author":"1","publication_status":"published","has_accepted_license":"1","pubrep_id":"1007","article_number":"16102","oa_version":"Published Version","ddc":["581"],"day":"01","abstract":[{"text":"The electrostatic charge at the inner surface of the plasma membrane is strongly negative in higher organisms.

Because of the properties of quantum rotations, the angular-momentum algebra can be of tremendous complexity even for a few interacting particles, such as valence electrons of an atom, not to mention larger many-particle systems. In this work, we study an example of the latter: A rotating quantum impurity coupled to a many-body bosonic bath. In the regime of strong impurity-bath couplings, the problem involves the addition of an infinite number of angular momenta, which renders it intractable using currently available techniques. Here, we introduce a novel canonical transformation that allows us to eliminate the complex angular-momentum algebra from such a class of many-body problems. In addition, the transformation exposes the problem's constants of motion, and renders it solvable exactly in the limit of a slowly rotating impurity. We exemplify the technique by showing that there exists a critical rotational speed at which the impurity suddenly acquires one quantum of angular momentum from the many-particle bath. Such an instability is accompanied by the deformation of the phonon density in the frame rotating along with the impurity."}],"publication":"Physical Review X","issue":"1","scopus_import":"1","corr_author":"1","publication_status":"published","pubrep_id":"652","has_accepted_license":"1","article_number":"011012","date_published":"2016-01-01T00:00:00Z","file_date_updated":"2020-07-14T12:44:45Z","citation":{"chicago":"Schmidt, Richard, and Mikhail Lemeshko. “Deformation of a Quantum Many-Particle System by a Rotating Impurity.” Physical Review X.

The observed planetary configuration has been shown to be unstable on a timescale much shorter than the estimated age of the system (~30 Myr) unless the planets are locked into mean motion resonances. This condition is characterised by small-amplitude libration of one or more resonant angles that stabilise the system by preventing close encounters. We simulate planetary systems similar to the HR 8799 planetary system, exploring the parameter space in separation between the orbits, planetary masses and distance from the Sun to the star. We find systems that look like HR 8799 and remain stable for longer than the estimated age of HR 8799. None of our systems are forced into resonances. We find, with nominal masses (Mb = 5 MJup and Mc,d,e = 7 MJup) and in a narrow range of orbit separations, that 5 of 100 systems match the observations and lifetime. Considering a broad range of orbit separations, we find 12 of 900 similar systems. The systems survive significantly longer because of their slightly increased initial orbit separations compared to assuming circular orbits from the observed positions. A small increase in separation leads to a significant increase in survival time. The low eccentricity the orbits develop from gravitational interaction is enough for the planets to match the observations. With lower masses, but still comfortably within the estimated planet mass uncertainty, we find 18 of 100 matching and long-lived systems in a narrow orbital separation range. In the broad separation range, we find 82 of 900 matching systems. Our results imply that the planets in the HR 8799 system do not have to be in strong mean motion resonances. We also investigate the future of wide-orbit planetary systems using our HR 8799 analogues. We find that 80% of the systems have two planets left after strong planet-planet scattering and these are on eccentric orbits with semi-major axes of a1 ~ 10 AU and a2 ~ 30−1000 AU. We speculate that other wide-orbit planetary systems, such as AB Pic and HD 106906, are the remnants of HR 8799 analogues that underwent close encounters and dynamical instability.","lang":"eng"}],"oa_version":"Published Version"},{"page":"31 - 42","_id":"1348","year":"2016","isi":1,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","publisher":"Springer","status":"public","type":"conference","date_updated":"2025-09-22T08:13:53Z","intvolume":" 9843","doi":"10.1007/978-3-319-44543-4_3","publist_id":"5901","date_published":"2016-08-09T00:00:00Z","volume":9843,"month":"08","article_processing_charge":"No","oa":1,"citation":{"chicago":"Fulek, Radoslav. “Bounded Embeddings of Graphs in the Plane,” 9843:31–42.

We present a runtime comparison between the (1+1) EA and two non-elitist nature-inspired algorithms, Strong Selection Weak Mutation (SSWM) and the Metropolis algorithm. While the (1+1) EA has to jump across the valley to a point of higher fitness because it does not accept decreasing moves, the non-elitist algorithms may cross the valley by accepting worsening moves. We show that while the runtime of the (1+1) EA algorithm depends critically on the length of the valley, the runtimes of the non-elitist algorithms depend crucially only on the depth of the valley. In particular, the expected runtime of both SSWM and Metropolis is polynomial in ℓ and exponential in d while the (1+1) EA is efficient only for valleys of small length.

Recurrent CA3–CA3\r\nsynapses are thought to be the subcellular substrate of pattern completion. However, the\r\nsynaptic mechanisms of this network computation remain enigmatic. To investigate these mechanisms, we combined functional connectivity analysis with network modeling.\r\nSimultaneous recording fromup to eight CA3 pyramidal neurons revealed that connectivity was sparse, spatially uniform, and highly enriched in disynaptic motifs (reciprocal, convergence,divergence, and chain motifs). Unitary connections were composed of one or two synaptic contacts, suggesting efficient use of postsynaptic space. Real-size modeling indicated that CA3 networks with sparse connectivity, disynaptic motifs, and single-contact connections robustly generated pattern completion.Thus, macro- and microconnectivity contribute to efficient\r\nmemory storage and retrieval in hippocampal networks."}],"day":"09","ddc":["570"],"publication":"Science","issue":"6304","oa_version":"Preprint","ec_funded":1,"pubrep_id":"823","has_accepted_license":"1","scopus_import":"1","publication_status":"published","corr_author":"1"},{"isi":1,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","_id":"1352","year":"2016","acknowledgement":"The authors are grateful to Florian Gebhard and Mikhail Lemeshko for discussions and critical reading of the manuscript.

Due to a breaking of the C4 symmetry, the coexisting phase inherently contains admixture of the s-wave pairing components. As a result, the superconducting gap exhibits nonstandard features including changed nodal directions. Our results also show that in the optimally doped regime the pure superconducting phase is typically unstable towards developing nematicity (breaking of the C4 symmetry). This has implications for the cuprate high-Tc superconductors, for which in this regime the so-called intertwined orders have recently been observed. Namely, the coexisting phase may be viewed as a precursor to such more involved patterns of symmetry breaking.","lang":"eng"}],"project":[{"grant_number":"291734","call_identifier":"FP7","name":"International IST Postdoc Fellowship Programme","_id":"25681D80-B435-11E9-9278-68D0E5697425"}],"ec_funded":1,"oa_version":"Preprint","article_number":"085152","publication_status":"published","scopus_import":"1","main_file_link":[{"open_access":"1","url":"http://arxiv.org/abs/1512.06688"}],"department":[{"_id":"MiLe"}],"title":"Coexistence of nematic order and superconductivity in the Hubbard model","author":[{"last_name":"Kaczmarczyk","first_name":"Jan","id":"46C405DE-F248-11E8-B48F-1D18A9856A87","full_name":"Kaczmarczyk, Jan","orcid":"0000-0002-1629-3675"},{"full_name":"Schickling, Tobias","last_name":"Schickling","first_name":"Tobias"},{"last_name":"Bünemann","full_name":"Bünemann, Jörg","first_name":"Jörg"}],"external_id":{"arxiv":["1512.06688"],"isi":["000382127700005"]}},{"year":"2016","page":"1033 - 1060","_id":"1353","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","isi":1,"intvolume":" 26","publisher":"World Scientific Publishing","status":"public","type":"journal_article","date_updated":"2025-09-22T08:10:54Z","publist_id":"5893","acknowledgement":"Libor Barto and Alexandr Kazda were supported by the the Grant Agency of the Czech Republic, grant GACR 13-01832S.
