Conceptually new applications could emerge, should these beneficial properties be manipulated by external stimuli in a reversible manner. One approach to render nanoporous frameworks responsive to external signals would be to immobilize molecular switches within their nanopores. Although the majority of molecular switches require conformational freedom to isomerize, and switching in the solid state is prohibited, the nanopores may provide enough room for the switches to efficiently isomerize. Here we describe two families of nanoporous materials incorporating the spiropyran molecular switch. These materials exhibit a variety of interesting properties, including reversible photochromism and acidochromism under solvent-free conditions, light-controlled capture and release of metal ions, as well reversible chromism induced by solvation/desolvation.","lang":"eng"}],"pmid":1,"type":"journal_article","citation":{"apa":"Kundu, P.

Incorporation of this switch onto macromolecular supports or inorganic scaffolds allows for the creation of robust dynamic materials. This review discusses the synthesis, switching conditions, and use of dynamic materials in which spiropyran has been attached to the surfaces of polymers, biomacromolecules, inorganic nanoparticles, as well as solid surfaces.

In this paper we consider distributed algorithms whose computations are organized in rounds. To verify the correctness of such algorithms, we reason about (i) properties (such as invariants) of the state, (ii) the transitions controlled by the algorithm, and (iii) the communication graph. We introduce a logic that addresses these points, and contains set comprehensions with cardinality constraints, function symbols to describe the local states of each process, and a limited form of quantifier alternation to express the verification conditions. We show its use in automating the verification of consensus algorithms. In particular, we give a semi-decision procedure for the unsatisfiability problem of the logic and identify a decidable fragment. We successfully applied our framework to verify the correctness of a variety of consensus algorithms tolerant to both benign faults (message loss, process crashes) and value faults (message corruption)."}],"type":"conference","quality_controlled":"1","month":"01","scopus_import":1,"_id":"1392","pubrep_id":"179","conference":{"start_date":"2014-01-19","name":"VMCAI: Verification, Model Checking and Abstract Interpretation","location":"San Diego, USA","end_date":"2014-01-21"},"alternative_title":["LNCS"],"publication_status":"published","date_created":"2018-12-11T11:51:45Z"},{"publist_id":"5816","oa_version":"Published Version","page":"167 - 181","date_updated":"2021-01-12T06:50:22Z","author":[{"first_name":"Andrew","full_name":"Gordon, Andrew","last_name":"Gordon"},{"first_name":"Thomas A","last_name":"Henzinger","full_name":"Henzinger, Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","orcid":"0000−0002−2985−7724"},{"full_name":"Nori, Aditya","last_name":"Nori","first_name":"Aditya"},{"full_name":"Rajamani, Sriram","last_name":"Rajamani","first_name":"Sriram"}],"title":"Probabilistic programming","article_processing_charge":"No","language":[{"iso":"eng"}],"status":"public","date_published":"2014-05-31T00:00:00Z","oa":1,"day":"31","doi":"10.1145/2593882.2593900","year":"2014","ec_funded":1,"publication":"Proceedings of the on Future of Software Engineering","project":[{"grant_number":"267989","name":"Quantitative Reactive Modeling","_id":"25EE3708-B435-11E9-9278-68D0E5697425","call_identifier":"FP7"},{"grant_number":"S 11407_N23","_id":"25832EC2-B435-11E9-9278-68D0E5697425","name":"Rigorous Systems Engineering","call_identifier":"FWF"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2018-12-11T11:51:45Z","publication_status":"published","conference":{"end_date":"2014-06-07","start_date":"2014-05-31","location":"Hyderabad, India","name":"FOSE: Future of Software Engineering"},"_id":"1393","scopus_import":1,"month":"05","quality_controlled":"1","citation":{"short":"A.

Models from diverse application areas such as computer vision, coding theory, cryptographic protocols, biology and reliability analysis can be written as probabilistic programs. Probabilistic inference is the problem of computing an explicit representation of the probability distribution implicitly specified by a probabilistic program. Depending on the application, the desired output from inference may vary-we may want to estimate the expected value of some function f with respect to the distribution, or the mode of the distribution, or simply a set of samples drawn from the distribution. In this paper, we describe connections this research area called \\Probabilistic Programming&quot; has with programming languages and software engineering, and this includes language design, and the static and dynamic analysis of programs.

A coherent superposition of electronic and rotational states of NO is prepared by impulsive stimulated Raman scattering and probed by simultaneous detection of HHG and SFI yields. We observe a fourfold higher sensitivity of high-harmonic generation to electronic dynamics and attribute it to the presence of inelastic quantum paths connecting coherently related electronic states [Kraus et al., Phys. Rev. Lett.111, 243005 (2013)]. Whereas different harmonic orders display very different sensitivities to rotational or electronic dynamics, strong-field ionization is found to be most sensitive to electronic motion. We introduce a general theoretical formalism for high-harmonic generation from coupled nuclear-electronic wave packets. We show that the unequal sensitivities of different harmonic orders to electronic or rotational dynamics result from the angle dependence of the photorecombination matrix elements which encode several autoionizing and shape resonances in the photoionization continuum of NO. We further study the dependence of rotational and electronic coherences on the intensity of the excitation pulse and support the observations with calculations.","lang":"eng"}],"pmid":1,"type":"journal_article","extern":"1","volume":171,"publisher":"Royal Society of Chemistry","date_created":"2023-08-10T06:38:19Z","publication_status":"published","external_id":{"pmid":["25415558"]},"_id":"14018","scopus_import":"1","month":"04","date_published":"2014-04-14T00:00:00Z","intvolume":"       171","doi":"10.1039/c4fd00018h","day":"14","publication_identifier":{"issn":["1359-6640"],"eissn":["1364-5498"]},"article_type":"original","year":"2014","publication":"Faraday Discussions","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"None","keyword":["Physical and Theoretical Chemistry"],"page":"113-132","date_updated":"2023-08-22T08:58:12Z","author":[{"first_name":"Denitsa Rangelova","last_name":"Baykusheva","full_name":"Baykusheva, Denitsa Rangelova","id":"71b4d059-2a03-11ee-914d-dfa3beed6530"},{"first_name":"Peter M.","last_name":"Kraus","full_name":"Kraus, Peter M."},{"first_name":"Song Bin","last_name":"Zhang","full_name":"Zhang, Song Bin"},{"full_name":"Rohringer, Nina","last_name":"Rohringer","first_name":"Nina"},{"first_name":"Hans Jakob","full_name":"Wörner, Hans Jakob","last_name":"Wörner"}],"title":"The sensitivities of high-harmonic generation and strong-field ionization to coupled electronic and nuclear dynamics","article_processing_charge":"No","language":[{"iso":"eng"}],"status":"public"},{"intvolume":"       141","date_published":"2014-08-14T00:00:00Z","doi":"10.1063/1.4890744","day":"14","article_type":"original","publication_identifier":{"issn":["0021-9606"],"eissn":["1089-7690"]},"year":"2014","article_number":"064317","publication":"The Journal of Chemical Physics","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"None","keyword":["Physical and Theoretical Chemistry","General Physics and Astronomy"],"date_updated":"2023-08-22T09:01:31Z","author":[{"full_name":"Vasilatou, K.","last_name":"Vasilatou","first_name":"K."},{"last_name":"Michaud","full_name":"Michaud, J.

The rotationally resolved spectra indicate a C(2v)-symmetric R0 structure for the ground electronic state of c-C3H₄⁺. Two vibrational modes of c-C3H₄⁺ are found to have vibrational wave numbers below 300 cm(-1), which is surprising for such a small cyclic hydrocarbon. The analysis of the isotopic shifts of the vibrational levels enabled the assignment of the lowest-frequency mode (fundamental wave number of ≈110 cm(-1) in c-C3H₄⁺) to the CH2 torsional mode (ν₈⁺, A2 symmetry) and of the second-lowest-frequency mode (≈210 cm(-1) in c-C3H₄⁺) to a mode combining a CH out-of-plane with a CH2 rocking motion (ν₁₅⁺, B2 symmetry). The potential energy along the CH2 torsional coordinate is flat near the equilibrium structure and leads to a pronounced anharmonicity."}],"citation":{"short":"K. Vasilatou, J.M. Michaud, D.R.

Carbon monoxide molecules are oriented by combining one-colour and delayed two-colour non-resonant femtosecond laser pulses. High-harmonic generation is used to probe the oriented wave-packet dynamics and reveals that a very high degree of orientation (Nup/Ntotal = 0.73–0.82) is achieved. We further extend this approach to orienting carbonyl sulphide molecules. We show that the present two-pulse scheme selectively enhances orientation created by the hyperpolarizability interaction whereas the ionization-depletion mechanism plays no role. We further control and optimize orientation through the delay between the one- and two-colour pump pulses.

In order to gain insight into the biophysical mechanism(s) underlying the tissue morphogenesis we studied the spreading of an epithelium during the early development of the zebrafish embryo. In zebrafish epiboly the enveloping cell layer (EVL), a simple squamous epithelium, spreads over the yolk cell to completely engulf it at the end of gastrulation. Previous studies have proposed that an actomyosin ring forming within the yolk syncytial layer (YSL) acts as purse string that through constriction along its circumference pulls on the margin of the EVL. Direct biophysical evidence for this hypothesis has however been missing. The aim of the thesis was to understand how the actomyosin ring may generate pulling forces onto the EVL and what cellular mechanism(s) may facilitate the spreading of the epithelium. Using laser ablation to measure cortical tension within the actomyosin ring we found an anisotropic tension distribution, which was highest along the circumference of the ring. However the low degree of anisotropy was incompatible with the actomyosin ring functioning as a purse string only. Additionally, we observed retrograde cortical flow from vegetal parts of the ring into the EVL margin. Interpreting the experimental data using a theoretical distribution that models  the tissues as active viscous gels led us to proposen that the actomyosin ring has a twofold contribution to EVL epiboly. It not only acts as a purse string through constriction along its circumference, but in addition constriction along the width of the ring generates pulling forces through friction-resisted cortical flow. Moreover, when rendering the purse string mechanism unproductive EVL epiboly proceeded normally indicating that the flow-friction mechanism is sufficient to drive the process. Aiming to understand what cellular mechanism(s) may facilitate the spreading of the epithelium we found that tension-oriented EVL cell divisions limit tissue anisotropy by releasing tension along the division axis and promote epithelial spreading. Notably, EVL cells undergo ectopic cell fusion in conditions in which oriented-cell division is impaired or the epithelium is mechanically challenged. Taken together our study of EVL epiboly suggests a novel mechanism of force generation for actomyosin rings through friction-resisted cortical flow and highlights the importance of tension-oriented cell divisions in epithelial morphogenesis.","lang":"eng"}],"type":"dissertation","month":"08","_id":"1403","alternative_title":["IST Austria Thesis"],"date_created":"2018-12-11T11:51:49Z","publication_status":"published","OA_place":"repository","ddc":["590"],"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","supervisor":[{"first_name":"Carl-Philipp J","orcid":"0000-0002-0912-4566","id":"39427864-F248-11E8-B48F-1D18A9856A87","last_name":"Heisenberg","full_name":"Heisenberg, Carl-Philipp J"}],"year":"2014","degree_awarded":"PhD","acknowledged_ssus":[{"_id":"SSU"}],"date_published":"2014-08-01T00:00:00Z","file":[{"date_updated":"2026-03-09T14:53:14Z","file_id":"21421","checksum":"67df5501b1b5b313c3bf9a360d713693","content_type":"application/pdf","relation":"main_file","creator":"cchlebak","file_size":24842978,"file_name":"2014 Behrnd final.pdf","date_created":"2026-03-09T14:53:14Z","access_level":"closed"}],"day":"01","has_accepted_license":"1","article_processing_charge":"No","file_date_updated":"2026-03-09T14:53:14Z","status":"public","language":[{"iso":"eng"}],"date_updated":"2026-03-09T14:56:18Z","related_material":{"record":[{"id":"2282","relation":"part_of_dissertation","status":"public"},{"relation":"part_of_dissertation","id":"2950","status":"public"},{"relation":"part_of_dissertation","id":"3373","status":"public"}]},"page":"91","title":"Forces driving epithelial spreading in zebrafish epiboly","author":[{"last_name":"Behrndt","full_name":"Behrndt, Martin","id":"3ECECA3A-F248-11E8-B48F-1D18A9856A87","first_name":"Martin"}],"oa_version":"None","publist_id":"5804"},{"oa_version":"Published Version","title":"Facile and scalable preparation of pure and dense DNA origami solutions","author":[{"first_name":"Evi","full_name":"Stahl, Evi","last_name":"Stahl"},{"last_name":"Martin","full_name":"Martin, Thomas","first_name":"Thomas"},{"id":"dfec9381-4341-11ee-8fd8-faa02bba7d62","last_name":"Praetorius","full_name":"Praetorius, Florian M","first_name":"Florian M"},{"last_name":"Dietz","full_name":"Dietz, Hendrik","first_name":"Hendrik"}],"date_updated":"2023-11-07T12:14:30Z","page":"12949-12954","status":"public","language":[{"iso":"eng"}],"article_processing_charge":"No","oa":1,"day":"17","doi":"10.1002/ange.201405991","date_published":"2014-11-17T00:00:00Z","intvolume":"       126","year":"2014","publication_identifier":{"issn":["1433-7851"],"eissn":["1521-3773"]},"article_type":"original","publication":"Angewandte Chemie International Edition","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","date_created":"2023-09-06T12:51:14Z","external_id":{"pmid":["25346175"]},"_id":"14301","month":"11","issue":"47","scopus_import":"1","citation":{"short":"E.

We established that the resulting radicals bind to Au, forming Au–C and Au–Br bonds. We show that the polymerization of the precursors follows Br desorption from Au, suggesting that the presence of halogens is the limiting factor in this step.

A nonequilibrium Green’s function approach based on self-energy corrected density functional theory and optimally tuned range-separated hybrid functionals is developed and used to understand experimental trends quantitatively. Importantly, due to the localized d states of the porphyrin molecules, hybrid functionals are essential for explaining measurements; standard semilocal functionals yield qualitatively incorrect results. Comparing directly with experiments, we show that the conductance can change by nearly a factor of 2 when different metal cations are used, counter to trends expected from gas-phase ionization energies which are relatively unchanged with the metal center. Our work explains the sensitivity of the porphyrin conductance with the metal center via a detailed and quantitative portrait of the interface electronic structure and provides a new framework for understanding transport quantitatively in complex junctions involving molecules with localized d states of relevance to light harvesting and energy conversion."}],"pmid":1,"type":"journal_article","extern":"1","OA_type":"closed access","volume":14,"publisher":"American Chemical Society"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication":"Journal of the American Chemical Society","article_type":"letter_note","year":"2014","publication_identifier":{"eissn":["1520-5126"],"issn":["0002-7863"]},"date_published":"2014-08-14T00:00:00Z","intvolume":"       136","doi":"10.1021/ja5061406","day":"14","article_processing_charge":"No","status":"public","language":[{"iso":"eng"}],"page":"12556-12559","date_updated":"2025-01-02T13:49:12Z","author":[{"first_name":"Arunabh","full_name":"Batra, Arunabh","last_name":"Batra"},{"last_name":"Kladnik","full_name":"Kladnik, Gregor","first_name":"Gregor"},{"full_name":"Gorjizadeh, Narjes","last_name":"Gorjizadeh","first_name":"Narjes"},{"first_name":"Jeffrey","full_name":"Meisner, Jeffrey","last_name":"Meisner"},{"first_name":"Michael","last_name":"Steigerwald","full_name":"Steigerwald, Michael"},{"last_name":"Nuckolls","full_name":"Nuckolls, Colin","first_name":"Colin"},{"first_name":"Su Ying","last_name":"Quek","full_name":"Quek, Su Ying"},{"first_name":"Dean","full_name":"Cvetko, Dean","last_name":"Cvetko"},{"first_name":"Alberto","last_name":"Morgante","full_name":"Morgante, Alberto"},{"first_name":"Latha","full_name":"Venkataraman, Latha","last_name":"Venkataraman","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","orcid":"0000-0002-6957-6089"}],"title":"Trimethyltin-mediated covalent Gold–Carbon bond formation","oa_version":"None","publisher":"American Chemical Society","volume":136,"quality_controlled":"1","citation":{"short":"A.
