Mutations selected in one environment may result in pleiotropic fitness trade-offs in subsequent novel environments, slowing the rates of adaptation. Epistatic interactions between mutations selected in sequential stressful environments may slow or accelerate subsequent rates of adaptation, depending on the nature of that interaction. We explored the dynamics of adaptation during sequential exposure to herbicides with different modes of action in Chlamydomonas reinhardtii. Evolution of resistance to two of the herbicides was largely independent of selection history. For carbetamide, previous adaptation to other herbicide modes of action positively impacted the likelihood of adaptation to this herbicide. Furthermore, while adaptation to all individual herbicides was associated with pleiotropic fitness costs in stress-free environments, we observed that accumulation of resistance mechanisms was accompanied by a reduction in overall fitness costs. We suggest that antagonistic epistasis may be a driving mechanism that enables populations to more readily adapt in novel environments. These findings highlight the potential for sequences of xenobiotics to facilitate the rapid evolution of multiple-drug and -pesticide resistance, as well as the potential for epistatic interactions between adaptive mutations to facilitate evolutionary rescue in rapidly changing environments."}],"type":"research_data_reference","year":"2014","article_processing_charge":"No","author":[{"first_name":"Mato","full_name":"Lagator, Mato","id":"345D25EC-F248-11E8-B48F-1D18A9856A87","last_name":"Lagator"},{"first_name":"Nick","full_name":"Colegrave, Nick","last_name":"Colegrave"},{"last_name":"Neve","full_name":"Neve, Paul","first_name":"Paul"}],"publisher":"Dryad","oa_version":"Published Version","date_created":"2021-07-28T08:48:06Z","status":"public","title":"Data from: Selection history and epistatic interactions impact dynamics of adaptation to novel environmental stresses","doi":"10.5061/dryad.85dn7","oa":1,"_id":"9741","date_published":"2014-08-21T00:00:00Z","user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","day":"21","month":"08"},{"user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","_id":"9747","oa":1,"date_published":"2014-04-17T00:00:00Z","doi":"10.5061/dryad.s42n1","title":"Data from: Role of sex and migration in adaptation to sink environments","status":"public","month":"04","day":"17","oa_version":"Published Version","publisher":"Dryad","author":[{"id":"345D25EC-F248-11E8-B48F-1D18A9856A87","first_name":"Mato","full_name":"Lagator, Mato","last_name":"Lagator"},{"full_name":"Morgan, Andrew","first_name":"Andrew","last_name":"Morgan"},{"last_name":"Neve","full_name":"Neve, Paul","first_name":"Paul"},{"first_name":"Nick","full_name":"Colegrave, Nick","last_name":"Colegrave"}],"article_processing_charge":"No","year":"2014","department":[{"_id":"CaGu"}],"date_updated":"2025-09-29T11:46:47Z","type":"research_data_reference","abstract":[{"lang":"eng","text":"Understanding the effects of sex and migration on adaptation to novel environments remains a key problem in evolutionary biology. Using a single-cell alga Chlamydomonas reinhardtii, we investigated how sex and migration affected rates of evolutionary rescue in a sink environment, and subsequent changes in fitness following evolutionary rescue. We show that sex and migration affect both the rate of evolutionary rescue and subsequent adaptation. However, their combined effects change as the populations adapt to a sink habitat. Both sex and migration independently increased rates of evolutionary rescue, but the effect of sex on subsequent fitness improvements, following initial rescue, changed with migration, as sex was beneficial in the absence of migration but constraining adaptation when combined with migration. These results suggest that sex and migration are beneficial during the initial stages of adaptation, but can become detrimental as the population adapts to its environment."}],"citation":{"apa":"Lagator, M., Morgan, A., Neve, P., &#38; Colegrave, N.

To investigate the effect of stimulus structure on redundancy in retina, we measured simultaneous responses from populations of retinal ganglion cells presented with natural and artificial stimuli that varied greatly in correlation structure; these stimuli and recordings are publicly available online. Responding to spatio-temporally structured stimuli such as natural movies, pairs of ganglion cells were modestly more correlated than in response to white noise checkerboards, but they were much less correlated than predicted by a non-adapting functional model of retinal response. Meanwhile, responding to stimuli with purely spatial correlations, pairs of ganglion cells showed increased correlations consistent with a static, non-adapting receptive field and nonlinearity. We found that in response to spatio-temporally correlated stimuli, ganglion cells had faster temporal kernels and tended to have stronger surrounds. These properties of individual cells, along with gain changes that opposed changes in effective contrast at the ganglion cell input, largely explained the pattern of pairwise correlations across stimuli where receptive field measurements were possible.","lang":"eng"}],"department":[{"_id":"GaTk"}],"date_updated":"2025-09-29T14:27:23Z","oa_version":"Published Version","publisher":"Dryad"},{"day":"08","month":"10","title":"Data from: Pupal cocoons affect sanitary brood care and limit fungal infections in ant colonies","status":"public","user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","date_published":"2014-10-08T00:00:00Z","_id":"9753","oa":1,"doi":"10.5061/dryad.nc0gc","date_created":"2021-07-30T08:24:11Z","citation":{"ista":"Tragust S, Ugelvig LV, Chapuisat M, Heinze J, Cremer S. 2014.

We here test whether the presence of a pupal cocoon, which occurs in some ant species but not in others, affects the sanitary brood care and fungal infection patterns after exposure to the entomopathogenic fungus Metarhizium brunneum. We use a) a comparative approach analysing four species with either naked or cocooned pupae and b) a within-species analysis of a single ant species, in which both pupal types co-exist in the same colony. Results: We found that the presence of a cocoon did not compromise fungal pathogen detection by the ants and that species with cocooned pupae increased brood grooming after pathogen exposure. All tested ant species further removed brood from their nests, which was predominantly expressed towards larvae and naked pupae treated with the live fungal pathogen. In contrast, cocooned pupae exposed to live fungus were not removed at higher rates than cocooned pupae exposed to dead fungus or a sham control. Consistent with this, exposure to the live fungus caused high numbers of infections and fungal outgrowth in larvae and naked pupae, but not in cocooned pupae. Moreover, the ants consistently removed the brood prior to fungal outgrowth, ensuring a clean brood chamber. Conclusion: Our study suggests that the pupal cocoon has a protective effect against fungal infection, causing an adaptive change in sanitary behaviours by the ants. It further demonstrates that brood removal - originally described for honeybees as “hygienic behaviour” – is a widespread sanitary behaviour in ants, which likely has important implications on disease dynamics in social insect colonies.","lang":"eng"}]},{"day":"03","publication_status":"published","publist_id":"6421","quality_controlled":0,"month":"10","status":"public","publication":"Physical Review Letters","title":"Interferometric probes of many-body localization","volume":113,"doi":"10.1103/PhysRevLett.113.147204","date_published":"2014-10-03T00:00:00Z","_id":"977","oa":1,"acknowledgement":"We thank E.

Theoretically, it has been predicted that the various Dirac cones, which are offset in energy and momentum, might harbour vastly different orbital character. However, their orbital texture, which is of immense importance in determining a variety of a materialâ €™ s properties remains elusive. Here, we unveil the orbital texture of Pb 1â ̂'x Sn x Se, a prototypical topological crystalline insulator. By using Fourier-transform scanning tunnelling spectroscopy we measure the interference patterns produced by the scattering of surface-state electrons. We discover that the intensity and energy dependences of the Fourier transforms show distinct characteristics, which can be directly attributed to orbital effects. Our experiments reveal a complex band topology involving two Lifshitz transitions and establish the orbital nature of the Dirac bands, which could provide an alternative pathway towards future quantum applications."}],"author":[{"last_name":"Zeljkovic","full_name":"Zeljkovic, Ilija","first_name":"Ilija"},{"last_name":"Okada","full_name":"Okada, Yoshinori","first_name":"Yoshinori"},{"first_name":"Chengyi","full_name":"Huang, Chengyi","last_name":"Huang"},{"last_name":"Sankar","full_name":"Sankar, Raman","first_name":"Raman"},{"last_name":"Walkup","first_name":"Daniel","full_name":"Walkup, Daniel"},{"full_name":"Zhou, Wenwen","first_name":"Wenwen","last_name":"Zhou"},{"last_name":"Serbyn","orcid":"0000-0002-2399-5827","id":"47809E7E-F248-11E8-B48F-1D18A9856A87","full_name":"Maksym Serbyn","first_name":"Maksym"},{"last_name":"Chou","full_name":"Chou, Fangcheng","first_name":"Fangcheng"},{"full_name":"Tsai, Wei-Feng","first_name":"Wei","last_name":"Tsai"},{"first_name":"Hsin","full_name":"Lin, Hsin","last_name":"Lin"},{"full_name":"Bansil, Arun","first_name":"Arun","last_name":"Bansil"},{"full_name":"Fu, Liang","first_name":"Liang","last_name":"Fu"},{"full_name":"Hasan, Md Z","first_name":"Md","last_name":"Hasan"},{"full_name":"Madhavan, Vidya","first_name":"Vidya","last_name":"Madhavan"}],"year":"2014","publisher":"Nature Publishing Group","intvolume":"        10","day":"01","publication_status":"published","publist_id":"6423","quality_controlled":0,"month":"08","status":"public","title":"Mapping the unconventional orbital texture in topological crystalline insulators","publication":"Nature Physics","volume":10,"doi":"10.1038/nphys3012","oa":1,"_id":"978","date_published":"2014-08-01T00:00:00Z","acknowledgement":"V.M. gratefully acknowledges funding from the US Department of Energy, Scanned Probe Division under Award Number DE-FG02-12ER46880 for the primary support of I.Z. and Y.O.

These surface states are protected by mirror symmetry with respect to the (110) plane. In this work we present a comprehensive study of the effects of different mirror-symmetry-breaking perturbations on the (001) surface band structure. Pristine (001) surface states have four branches of Dirac fermions at low energy. We show that ferroelectric-type structural distortion generates a mass and gaps out some or all of these Dirac points, while strain shifts Dirac points in the Brillouin zone. An in-plane magnetic field leaves the surface state gapless, but introduces asymmetry between Dirac points. Finally, an out-of-plane magnetic field leads to discrete Landau levels. We show that the Landau level spectrum has an unusual pattern of degeneracy and interesting features due to the unique underlying band structure. This suggests that Landau level spectroscopy can detect and distinguish between different mechanisms of symmetry breaking in topological crystalline insulators."}],"intvolume":"        90","publisher":"American Physical Society","extern":1,"date_created":"2018-12-11T11:49:31Z","issue":"3","status":"public","volume":90,"title":"Symmetry breaking and Landau quantization in topological crystalline insulators","publication":"Physical Review B - Condensed Matter and Materials Physics","date_published":"2014-07-03T00:00:00Z","_id":"979","oa":1,"doi":"10.1103/PhysRevB.90.035402","acknowledgement":"We thank V.

In this paper, using analytic arguments and numerical simulations, we study the behavior of local observables in an isolated MBL system following a quantum quench. For the case of a global quench, we find that the local observables reach stationary, highly nonthermal values at long times as a result of slow dephasing characteristic of the MBL phase. These stationary values retain the local memory of the initial state due to the existence of local integrals of motion in the MBL phase. The temporal fluctuations around stationary values exhibit universal power-law decay in time, with an exponent set by the localization length and the diagonal entropy of the initial state. Such a power-law decay holds for any local observable and is related to the logarithmic in time growth of entanglement in the MBL phase. This behavior distinguishes the MBL phase from both the Anderson insulator (where no stationary state is reached) and from the ergodic phase (where relaxation is expected to be exponential). For the case of a local quench, we also find a power-law approach of local observables to their stationary values when the system is prepared in a mixed state. Quench protocols considered in this paper can be naturally implemented in systems of ultracold atoms in disordered optical lattices, and the behavior of local observables provides a direct experimental signature of many-body localization."}],"author":[{"orcid":"0000-0002-2399-5827","last_name":"Serbyn","full_name":"Maksym Serbyn","first_name":"Maksym","id":"47809E7E-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Papić","first_name":"Zlatko","full_name":"Papić, Zlatko"},{"first_name":"Dmitry","full_name":"Abanin, Dmitry A","last_name":"Abanin"}],"year":"2014","publisher":"American Physical Society","intvolume":"        90","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1408.4105"}],"citation":{"ieee":"M.

On the Galápagos Islands, the invasive parasitic fly Philornis downsi poses a major threat to the endemic avifauna. Here, we investigated the influence of this parasite on the breeding success of two Darwin's finch species, the warbler finch (Certhidea olivacea) and the sympatric small tree finch (Camarhynchus parvulus), on Santa Cruz Island in 2010 and 2012. While the population of the small tree finch appeared to be stable, the warbler finch has experienced a dramatic decline in population size on Santa Cruz Island since 1997. We aimed to identify whether warbler finches are particularly vulnerable during different stages of the breeding cycle. Contrary to our prediction, breeding success was lower in the small tree finch than in the warbler finch. In both species P. downsi had a strong negative impact on breeding success and our data suggest that heavy rain events also lowered the fledging success. On the one hand parents might be less efficient in compensating their chicks' energy loss due to parasitism as they might be less efficient in foraging on days of heavy rain. On the other hand, intense rainfalls might lead to increased humidity and more rapid cooling of the nests. In the case of the warbler finch we found that the control of invasive plant species with herbicides had a significant additive negative impact on the breeding success. It is very likely that the availability of insects (i.e. food abundance) is lower in such controlled areas, as herbicide usage led to the removal of the entire understory. Predation seems to be a minor factor in brood loss.","lang":"eng"}],"date_updated":"2025-09-29T13:19:35Z","year":"2014","author":[{"last_name":"Cimadom","first_name":"Arno","full_name":"Cimadom, Arno"},{"first_name":"Angel","full_name":"Ulloa, Angel","last_name":"Ulloa"},{"last_name":"Meidl","id":"4709BCE6-F248-11E8-B48F-1D18A9856A87","full_name":"Meidl, Patrick","first_name":"Patrick"},{"full_name":"Zöttl, Markus","first_name":"Markus","last_name":"Zöttl"},{"full_name":"Zöttl, Elisabet","first_name":"Elisabet","last_name":"Zöttl"},{"full_name":"Fessl, Birgit","first_name":"Birgit","last_name":"Fessl"},{"full_name":"Nemeth, Erwin","first_name":"Erwin","last_name":"Nemeth"},{"first_name":"Michael","full_name":"Dvorak, Michael","last_name":"Dvorak"},{"full_name":"Cunninghame, Francesca","first_name":"Francesca","last_name":"Cunninghame"},{"full_name":"Tebbich, Sabine","first_name":"Sabine","last_name":"Tebbich"}],"article_processing_charge":"No","quality_controlled":"1","month":"09","ddc":["576"],"publist_id":"7352","title":"Invasive parasites habitat change and heavy rainfall reduce breeding success in Darwin's finches","volume":9,"status":"public","acknowledgement":"The study was funded by the University of Vienna (Focus of Excellence grant), the Galápagos Conservation Trust, and the Ethologische Gesellschaft e.V.","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","_id":"468","pubrep_id":"954","date_created":"2018-12-11T11:46:38Z","citation":{"chicago":"Cimadom, Arno, Angel Ulloa, Patrick Meidl, Markus Zöttl, Elisabet Zöttl, Birgit Fessl, Erwin Nemeth, Michael Dvorak, Francesca Cunninghame, and Sabine Tebbich. “Invasive Parasites Habitat Change and Heavy Rainfall Reduce Breeding Success in Darwin’s Finches.” <i>PLoS One</i>.

The winner is determined by some fixed property Y of the sequence of labels of the edges (or nodes) forming this cycle. These games are traditionally of interest because of their connection with infinite-duration games such as parity and mean-payoff games. We study the memory requirements for winning strategies of FCGs and certain associated infinite duration games. We exhibit a simple FCG that is not memoryless determined (this corrects a mistake in Memoryless determinacy of parity and mean payoff games: a simple proof by Bj⋯orklund, Sandberg, Vorobyov (2004) that claims that FCGs for which Y is closed under cyclic permutations are memoryless determined). We show that θ (n)! memory (where n is the number of nodes in the graph), which is always sufficient, may be necessary to win some FCGs. On the other hand, we identify easy to check conditions on Y (i.e., Y is closed under cyclic permutations, and both Y and its complement are closed under concatenation) that are sufficient to ensure that the corresponding FCGs and their associated infinite duration games are memoryless determined. We demonstrate that many games considered in the literature, such as mean-payoff, parity, energy, etc., satisfy these conditions. On the complexity side, we show (for efficiently computable Y) that while solving FCGs is in PSPACE, solving some families of FCGs is PSPACE-hard.

It is one of the rare and intriguing combinatorial problems that lie in NP∩co-NP, but are not known to be in P. The existence of polynomial-time algorithms has been a major open problem for decades and apart from pseudopolynomial algorithms there is no algorithm that solves any non-trivial subclass in polynomial time. In this paper, we give several results based on the weight structures of the graph. First, we identify a notion of penalty and present a polynomial-time algorithm when the penalty is large. Our algorithm is the first polynomial-time algorithm on a large class of weighted graphs. It includes several worst-case instances on which previous algorithms, such as value iteration and random facet algorithms, require at least sub-exponential time. Our main technique is developing the first non-trivial approximation algorithm and showing how to convert it to an exact algorithm. Moreover, we show that in a practical case in verification where weights are clustered around a constant number of values, the energy game problem can be solved in polynomial time. We also show that the problem is still as hard as in general when the clique-width is bounded or the graph is strongly ergodic, suggesting that restricting the graph structure does not necessarily help."}],"oa_version":"Preprint","arxiv":1,"page":"457 - 492","related_material":{"record":[{"id":"10905","relation":"earlier_version","status":"public"}]},"main_file_link":[{"url":"https://arxiv.org/abs/1604.08234","open_access":"1"}],"article_type":"original","publist_id":"7282","month":"11","quality_controlled":"1","_id":"535","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","status":"public","volume":70,"title":"Polynomial-time algorithms for energy games with special weight structures"},{"date_created":"2018-12-11T11:47:02Z","pubrep_id":"934","citation":{"mla":"Prizak, Roshan, et al. “Fitness Consequences of Maternal and Grandmaternal Effects.” <i>Ecology and Evolution</i>, vol. 4, no. 15, Wiley-Blackwell, 2014, pp. 3139–45, doi:<a href=\"https://doi.org/10.1002/ece3.1150\">10.1002/ece3.1150</a>.","ista":"Prizak R, Ezard T, Hoyle R. 2014.

Despite mounting evidence that multigenerational effects alter phenotypic and life-history traits, our understanding of how they combine to determine fitness is not well developed because of the added complexity necessary to study them. Here, we derive a quantitative genetic model of adaptation to an extraordinary new environment by an additive genetic component, phenotypic plasticity, maternal and grandmaternal effects. We show how, at equilibrium, negative maternal and negative grandmaternal effects maximize expected population mean fitness. We define negative transgenerational effects as those that have a negative effect on trait expression in the subsequent generation, that is, they slow, or potentially reverse, the expected evolutionary dynamic. When maternal effects are positive, negative grandmaternal effects are preferred. As expected under Mendelian inheritance, the grandmaternal effects have a lower impact on fitness than the maternal effects, but this dual inheritance model predicts a more complex relationship between maternal and grandmaternal effects to constrain phenotypic variance and so maximize expected population mean fitness in the offspring."}],"date_updated":"2025-09-29T13:17:53Z","author":[{"first_name":"Roshan","full_name":"Prizak, Roshan","id":"4456104E-F248-11E8-B48F-1D18A9856A87","last_name":"Prizak"},{"last_name":"Ezard","full_name":"Ezard, Thomas","first_name":"Thomas"},{"full_name":"Hoyle, Rebecca","first_name":"Rebecca","last_name":"Hoyle"}],"year":"2014","article_processing_charge":"No","oa_version":"Published Version","has_accepted_license":"1","publist_id":"7280","month":"07","ddc":["530","571"],"status":"public","title":"Fitness consequences of maternal and grandmaternal effects","volume":4,"_id":"537","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345"},{"publication_identifier":{"issn":["2664-1690"]},"pubrep_id":"152","date_created":"2018-12-12T11:39:11Z","publisher":"IST Austria","has_accepted_license":"1","oa_version":"Published Version","department":[{"_id":"ToHe"}],"type":"technical_report","date_updated":"2025-09-29T11:40:47Z","abstract":[{"text":"Model-based testing is a promising technology for black-box software and hardware testing, in which test cases are generated automatically from high-level specifications. Nowadays, systems typically consist of multiple interacting components and, due to their complexity, testing presents a considerable portion of the effort and cost in the design process. Exploiting the compositional structure of system specifications can considerably reduce the effort in model-based testing. Moreover, inferring properties about the system from testing its individual components allows the designer to reduce the amount of integration testing.\r\nIn this paper, we study compositional properties of the IOCO-testing theory. We propose a new approach to composition and hiding operations, inspired by contract-based design and interface theories. These operations preserve behaviors that are compatible under composition and hiding, and prune away incompatible ones. The resulting specification characterizes the input sequences for which the unit testing of components is sufficient to infer the correctness of component integration without the need for further tests. We provide a methodology that uses these results to minimize integration testing effort, but also to detect potential weaknesses in specifications. While we focus on asynchronous models and the IOCO conformance relation, the resulting methodology can be applied to a broader class of systems.","lang":"eng"}],"year":"2014","author":[{"last_name":"Daca","id":"49351290-F248-11E8-B48F-1D18A9856A87","first_name":"Przemyslaw","full_name":"Daca, Przemyslaw"},{"orcid":"0000−0002−2985−7724","last_name":"Henzinger","first_name":"Thomas A","full_name":"Henzinger, Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Krenn, Willibald","first_name":"Willibald","last_name":"Krenn"},{"last_name":"Nickovic","full_name":"Nickovic, Dejan","first_name":"Dejan","id":"41BCEE5C-F248-11E8-B48F-1D18A9856A87"}],"citation":{"mla":"Daca, Przemyslaw, et al. <i>Compositional Specifications for IOCO Testing</i>.

In this paper we adapt a quantitative framework, called model measuring, to the hybrid systems domain. The model-measuring problem asks, given a model M and a specification, what is the maximal distance such that all models within that distance from M satisfy (or violate) the specification. A distance function on models is given as part of the input of the problem. Distances, especially related to continuous behaviors are more natural in the hybrid case than the discrete case. We are interested in distances represented by monotonic hybrid automata, a hybrid counterpart of (discrete) weighted automata, whose recognized timed languages are monotone (w.r.t. inclusion) in the values of parameters.The contributions of this paper are twofold.

We concentrate on automatic distance functions, which are defined by weighted automata.\r\nThe model-measuring problem subsumes several generalizations of the classical model-checking problem, in particular, quantitative model-checking problems that measure the degree of satisfaction of a specification, and robustness problems that measure how much a model can be perturbed without violating the specification.\r\nWe show that for automatic distance functions, and ω-regular linear-time and branching-time specifications, the model-measuring problem can be solved.\r\nWe use automata-theoretic model-checking methods for model measuring, replacing the emptiness question for standard word and tree automata by the optimal-weight question for the weighted versions of these automata. We consider weighted automata that accumulate weights by maximizing, summing, discounting, and limit averaging. \r\nWe give several examples of using the model-measuring problem to compute various notions of robustness and quantitative satisfaction for temporal specifications."}],"type":"technical_report","year":"2014","author":[{"first_name":"Thomas A","full_name":"Henzinger, Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","last_name":"Henzinger","orcid":"0000−0002−2985−7724"},{"id":"2FC5DA74-F248-11E8-B48F-1D18A9856A87","full_name":"Otop, Jan","first_name":"Jan","last_name":"Otop"}],"publisher":"IST Austria","oa_version":"Published Version","has_accepted_license":"1","date_created":"2018-12-12T11:39:13Z","pubrep_id":"175","publication_identifier":{"issn":["2664-1690"]},"file":[{"file_id":"5481","access_level":"open_access","date_updated":"2020-07-14T12:46:49Z","creator":"system","date_created":"2018-12-12T11:53:20Z","file_size":383052,"content_type":"application/pdf","file_name":"IST-2014-172-v1+1_report.pdf","relation":"main_file","checksum":"fcc3eab903cfcd3778b338d2d0d44d18"}],"status":"public","language":[{"iso":"eng"}],"file_date_updated":"2020-07-14T12:46:49Z","title":"From model checking to model measuring","doi":"10.15479/AT:IST-2014-172-v1-1","date_published":"2014-02-19T00:00:00Z","_id":"5417","oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"19","publication_status":"published","alternative_title":["IST Austria Technical Report"],"month":"02","ddc":["000"]}]
