Here we perform a direct evaluation of the Tolman length from atomistic simulations of a solid-liquid planar interface in out-of-equilibrium conditions, by first computing the surface tension from the amplitude of thermal capillary fluctuations of a localized version of the Gibbs dividing surface and by then calculating how much the surface energy changes when it is defined relative to the equimolar dividing surface. We computed δ for a model potential, and found a good agreement with the values indirectly inferred from nucleation simulations. The agreement not only validates our approach but also suggests that the nucleation free energy of the system can be perfectly described using classical nucleation theory if the Tolman length is taken into account."}],"issue":"23","user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","_id":"9659","title":"Communication: Computing the Tolman length for solid-liquid interfaces","status":"public","intvolume":" 148","oa_version":"Submitted Version","scopus_import":"1","day":"21","article_processing_charge":"No","publication":"The Journal of Chemical Physics","citation":{"ama":"Cheng B, Ceriotti M.

Model simulations with the physically based glacio-hydrological model TOPKAPI-ETH reveal a period of neutral or slightly positive mass balance between 2000 and 2010, followed by a transition to increasingly large annual mass losses, associated with a recent mega drought. Mass losses commence earlier, and are more severe, for a heavily debris-covered glacier, most likely due to its strong dependence on snow avalanche accumulation, which has declined in recent years. Catchment runoff shows a marked decreasing trend over the study period, but with high interannual variability directly linked to winter snow accumulation, and high contribution from ice melt in dry periods and drought conditions. The study demonstrates the importance of incorporating local-scale processes such as snow avalanche accumulation and spatially variable debris thickness, in understanding the responses of different glacier types to climate change. We highlight the increased dependency of runoff from high Andean catchments on the diminishing resource of glacier ice during dry years.","lang":"eng"}],"issue":"2","type":"journal_article","oa_version":"Published Version","_id":"12603","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Interannual variability in glacier contribution to runoff from a high‐elevation Andean catchment: Understanding the role of debris cover in glacier hydrology","status":"public","intvolume":" 33"},{"_id":"12605","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Snow depth structure, fractal behavior, and interannual consistency over Haut Glacier d'Arolla, Switzerland","status":"public","intvolume":" 54","oa_version":"Published Version","type":"journal_article","abstract":[{"lang":"eng","text":"Snow depth patterns over glaciers are controlled by precipitation, snow redistribution due to wind and avalanches, and the exchange of energy with the atmosphere that determines snow ablation.

We analyze snow depth on Haut Glacier d'Arolla, Switzerland, in the two winter seasons 2006–2007 and 2010–2011 to (1) understand whether snow depth over an alpine glacier at the end of the accumulation season exhibits a behavior similar to the one observed on single slopes and vegetated areas; and (2) investigate the snow pattern consistency over the two accumulation seasons. We perform this analysis on a data set of high-resolution lidar-derived snow depth using variograms and fractal parameters. Our first main result is that snow depth patterns on the glacier exhibit a multiscale behavior, with a scale break around 20 m after which the fractal dimension increases, indicating more autocorrelated structure before the scale break than after. Second, this behavior is consistent over the two years, with fractal parameters and their spatial variability almost constant in the two seasons. We also show that snow depth patterns exhibit a distinct behavior in the glacier tongue and the upper catchment, with longer correlation distances on the tongue in the direction of the main winds, suggesting spatial distinctions that are likely induced by different processes and that should be taken into account when extrapolating snow depth from limited samples."}],"issue":"10","publication":"Water Resources Research","citation":{"apa":"Clemenzi, I., Pellicciotti, F., & Burlando, P.

Many of these glaciers are partially covered by rocky debris, which protects the ice from solar radiation and warm air. However, studies have found that the surface of these debris-covered glaciers is actually lowering as fast as glaciers without debris. Water ponded on the surface of the glaciers may be partially responsible, as water can absorb atmospheric energy very efficiently. However, the overall effect of these ponds has not been thoroughly assessed yet. We study a valley in Nepal for which we have extensive weather measurements, and we use a numerical model to calculate the energy absorbed by ponds on the surface of the glaciers over 6 months. As we have not observed each individual pond thoroughly, we run the model 5,000 times with different setups. We find that ponds are extremely important for glacier melt and absorb energy 14 times as quickly as the debris-covered ice.

Early field observations had advanced a hypothesis of survival of north-facing and disappearance of south-facing cliffs, which is central for predicting the contribution of cliffs to total glacier mass losses. Their role as windows of energy transfer suggests they may explain the anomalously high mass losses of debris-covered glaciers in High Mountain Asia (HMA) despite the insulating debris, currently at the center of a debated controversy. We use a 3D model of cliff evolution coupled to very high-resolution topographic data to demonstrate that ice cliffs facing south (in the Northern Hemisphere) disappear within a few months due to enhanced solar radiation receipts and that aspect is the key control on cliffs evolution. We reproduce continuous flattening of south-facing cliffs, a result of their vertical gradient of incoming solar radiation and sky view factor. Our results establish that only north-facing cliffs are recurrent features and thus stable contributors to the melting of debris-covered glaciers. Satellite observations and mass balance modeling confirms that few south-facing cliffs of small size exist on the glaciers of Langtang, and their contribution to the glacier volume losses is very small (∼1%). This has major implications for the mass balance of HMA debris-covered glaciers as it provides the basis for new parameterizations of cliff evolution and distribution to constrain volume losses in a region where glaciers are highly relevant as water sources for millions of people."}],"issue":"17","type":"journal_article","oa_version":"Published Version","status":"public","title":"Aspect controls the survival of ice cliffs on debris-covered glaciers","intvolume":" 115","_id":"12607","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"09","article_processing_charge":"No","scopus_import":"1","date_published":"2018-04-09T00:00:00Z","article_type":"original","page":"4369-4374","publication":"PNAS","citation":{"ama":"Buri P, Pellicciotti F.

Here, we suggest a universal and computationally efficient scheme to model the irradiation of supported 2D materials, which combines analytical potential molecular dynamics with Monte Carlo simulations and makes it possible to independently assess the contributions to the damage from backscattered ions and atoms sputtered from the substrate. Using the scheme, we study the defect production in graphene and MoS2 sheets, which are the two most important and wide-spread 2D materials, deposited on a SiO2 substrate. For helium and neon ions with a wide range of initial ion energies including those used in a commercial helium ion microscope (HIM), we demonstrate that depending on the ion energy and mass, the defect production in 2D systems can be dominated by backscattered ions and sputtered substrate atoms rather than by the direct ion impacts and that the amount of damage in 2D materials heavily depends on whether a substrate is present or not. We also study the factors which limit the spatial resolution of the patterning process. Our results, which agree well with the available experimental data, provide not only insights into defect production but also quantitative information, which can be used for the minimization of damage during imaging in HIM or optimization of the patterning process.","lang":"eng"}],"_id":"13255","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","intvolume":" 10","status":"public","title":"Supported two-dimensional materials under ion irradiation: The substrate governs defect production","oa_version":"None","keyword":["General Materials Science"],"article_processing_charge":"No","day":"17","citation":{"mla":"Kretschmer, Silvan, et al. “Supported Two-Dimensional Materials under Ion Irradiation: The Substrate Governs Defect Production.” ACS Applied Materials & Interfaces, vol. 10, no. 36, American Chemical Society, 2018, pp. 30827–36, doi:10.1021/acsami.8b08471.","short":"S.

However, molecular switching events often entail large structural changes and therefore require conformational freedom, which is typically limited under confinement conditions. Here, we investigated the behavior of azobenzene—the key building block of light-controlled molecular machines—in a confined environment that is flexible and can adapt its shape to that of the bound guest. To this end, we encapsulated several structurally diverse azobenzenes within the cavity of a flexible, water-soluble coordination cage, and investigated their light-responsive behavior. Using UV/Vis absorption spectroscopy and a combination of NMR methods, we showed that each of the encapsulated azobenzenes exhibited distinct switching properties. An azobenzene forming a 1:1 host–guest inclusion complex could be efficiently photoisomerized in a reversible fashion. In contrast, successful switching in inclusion complexes incorporating two azobenzene guests was dependent on the availability of free cages in the system, and it involved reversible trafficking of azobenzene between the cages. In the absence of extra cages, photoswitching was either suppressed or it involved expulsion of azobenzene from the cage and consequently its precipitation from the solution. This finding was utilized to develop an information storage medium in which messages could be written and erased in a reversible fashion using light."}],"_id":"13376","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","intvolume":" 115","title":"Reversible photoswitching of encapsulated azobenzenes in water","status":"public","oa_version":"Published Version"},{"status":"public","title":"Reversible chromism of spiropyran in the cavity of a flexible coordination cage","intvolume":" 9","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"13374","oa_version":"Published Version","type":"journal_article","abstract":[{"lang":"eng","text":"Confining molecules to volumes only slightly larger than the molecules themselves can profoundly alter their properties. Molecular switches—entities that can be toggled between two or more forms upon exposure to an external stimulus—often require conformational freedom to isomerize.

To preserve the switchability of these species under confinement, we work with a water-soluble coordination cage that is flexible enough to adapt its shape to the conformation of the encapsulated guest. We show that owing to its flexibility, the cage is not only capable of accommodating—and solubilizing in water—several light-responsive spiropyran-based molecular switches, but, more importantly, it also provides an environment suitable for the efficient, reversible photoisomerization of the bound guests.

We compute the first grid of evolutionary and spectral models specially made for stars stripped in binaries for a range of progenitor masses (2–20 M⊙) and metallicities ranging from solar to values representative for pop II stars. For stripped stars with masses in the range 0.3–7 M⊙, we find consistently high effective temperatures (20 000–100 000 K, increasing with mass), small radii (0.2–1 R⊙), and high bolometric luminosities, comparable to that of their progenitor before stripping. The spectra show a continuous sequence that naturally bridges subdwarf-type stars at the low-mass end and Wolf-Rayet-like spectra at the high-mass end. For intermediate masses we find hybrid spectral classes showing a mixture of absorption and emission lines. These appear for stars with mass-loss rates of 10−8−10−6 M⊙ yr−1, which have semi-transparent atmospheres. At low metallicity, substantial hydrogen-rich layers are left at the surface and we predict spectra that resemble O-type stars instead. We obtain spectra undistinguishable from subdwarfs for stripped stars with masses up to 1.7 M⊙, which questions whether the widely adopted canonical value of 0.47 M⊙ is uniformly valid. Only a handful of stripped stars of intermediate mass have currently been identified observationally. Increasing this sample will provide necessary tests for the physics of interaction, internal mixing, and stellar winds. We use our model spectra to investigate the feasibility to detect stripped stars next to an optically bright companion and recommend systematic searches for their UV excess and possible emission lines, most notably HeII λ4686 in the optical and HeII λ1640 in the UV. Our models are publicly available for further investigations or inclusion in spectral synthesis simulations.","lang":"eng"}],"type":"journal_article","language":[{"iso":"eng"}],"doi":"10.1051/0004-6361/201732274","quality_controlled":"1","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1051/0004-6361/201732274"}],"external_id":{"arxiv":["1802.03018"]},"oa":1,"month":"07","publication_identifier":{"issn":["0004-6361"],"eissn":["1432-0746"]},"date_created":"2023-08-03T10:15:00Z","date_updated":"2023-08-09T11:22:17Z","volume":615,"author":[{"first_name":"Ylva Louise Linsdotter","last_name":"Götberg","id":"d0648d0c-0f64-11ee-a2e0-dd0faa2e4f7d","orcid":"0000-0002-6960-6911","full_name":"Götberg, Ylva Louise Linsdotter"},{"first_name":"S.

They bear astrophysical significance as sources of UV and ionizing radiation in older stellar populations and, if sufficiently massive, as stripped supernova progenitors. Binary evolutionary models predict that they are common, but only a handful of subdwarfs with B-type companions are known. The question is whether a large population of such systems has evaded detection as a result of biases, or whether the model predictions are wrong. We reanalyze the well-studied post-interaction binary φ Persei. Recently, new data have improved the orbital solution of the system, which contains an ~1.2M⊙ stripped-envelope star and a rapidly rotating ~9.6M⊙ Be star. We compare with an extensive grid of evolutionary models using a Bayesian approach and constrain the initial masses of the progenitor to 7.2 ± 0.4M⊙ for the stripped star and 3.8 ± 0.4M⊙ for the Be star. The system must have evolved through near-conservative mass transfer. These findings are consistent with earlier studies. The age we obtain, 57 ± 9 Myr, is in excellent agreement with the age of the α Persei cluster. We note that neither star was initially massive enough to produce a core-collapse supernova, but mass exchange pushed the Be star above the mass threshold. We find that the subdwarf is overluminous for its mass by almost an order of magnitude, compared to the expectations for a helium core burning star. We can only reconcile this if the subdwarf resides in a late phase of helium shell burning, which lasts only 2–3% of the total lifetime as a subdwarf. Assuming continuous star formation implies that up to ~50 less evolved, dimmer subdwarfs exist for each system similar to φ Persei, but have evaded detection so far. Our findings can be interpreted as a strong indication that a substantial population of stripped-envelope stars indeed exists, but has so far evaded detection because of observational biases and lack of large-scale systematic searches.","lang":"eng"}],"type":"journal_article"},{"publication_identifier":{"eissn":["1365-2966"],"issn":["0035-8711"]},"month":"03","quality_controlled":"1","external_id":{"arxiv":["1704.03516"]},"main_file_link":[{"url":"https://doi.org/10.1093/mnras/stx3181","open_access":"1"}],"oa":1,"language":[{"iso":"eng"}],"doi":"10.1093/mnras/stx3181","extern":"1","publisher":"Oxford University Press","publication_status":"published","year":"2018","volume":475,"date_created":"2023-08-03T10:14:47Z","date_updated":"2023-08-09T12:17:34Z","author":[{"full_name":"Smith, Nathan","last_name":"Smith","first_name":"Nathan"},{"first_name":"Ylva Louise Linsdotter","last_name":"Götberg","id":"d0648d0c-0f64-11ee-a2e0-dd0faa2e4f7d","orcid":"0000-0002-6960-6911","full_name":"Götberg, Ylva Louise Linsdotter"},{"first_name":"Selma E","last_name":"de Mink","full_name":"de Mink, Selma E"}],"keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"scopus_import":"1","article_processing_charge":"No","day":"01","page":"772-782","article_type":"original","citation":{"ista":"Smith N, Götberg YLL, de Mink SE. 2018.

WN3/O3 spectra exhibit both WR-like emission and O3 V-like absorption – but at lower luminosity than O3 V or WN stars. We examine the projected spatial distribution of WN3/O3 stars in the Large Magellanic Cloud as compared to O-type stars. Surprisingly, WN3/O3 stars are among the most isolated of all classes of massive stars; they have a distribution similar to red supergiants dominated by initial masses of 10–15 M⊙, and are far more dispersed than classical WR stars or luminous blue variables. Their lack of association with clusters of O-type stars suggests strongly that WN3/O3 stars are not the descendants of single massive stars (30 M⊙ or above). Instead, they are likely products of interacting binaries at lower initial mass (10–18 M⊙). Comparison with binary models suggests a probable origin with primaries in this mass range that were stripped of their H envelopes through non-conservative mass transfer by a low-mass secondary. We show that model spectra and positions on the Hertzsprung–Russell diagram for binary-stripped stars are consistent with WN3/O3 stars. Monitoring radial velocities with high-resolution spectra can test for low-mass companions or runaway velocities. With lower initial mass and environments that avoid very massive stars, the WN3/O3 stars fit expectations for progenitors of Type Ib and possibly Type Ibn supernovae.","lang":"eng"}],"intvolume":" 475","status":"public","title":"Extreme isolation of WN3/O3 stars and implications for their evolutionary origin as the elusive stripped binaries","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"13474","oa_version":"Published Version"},{"abstract":[{"text":"A drawing of a graph on a surface is independently even if every pair of nonadjacent edges in the drawing crosses an even number of times.

The observation and quantification of chirality-sensitive signals, however, remains extremely challenging, especially on ultrafast timescales and in dilute media. Here, we describe the experimental realization of an all-optical and ultrafast scheme for detecting chiral dynamics in molecules. This technique is based on high-harmonic generation by a combination of two-color counterrotating femtosecond laser pulses with polarization states tunable from linear to circular. We demonstrate two different implementations of chiral-sensitive high-harmonic spectroscopy on an ensemble of randomly oriented methyloxirane molecules in the gas phase. Using two elliptically polarized fields, we observe that the ellipticities maximizing the harmonic signal reach up to \r\n4.4\r\n±\r\n0.2\r\n%\r\n (at 17.6 eV). Using two circularly polarized fields, we observe circular dichroisms ranging up to \r\n13\r\n±\r\n6\r\n%\r\n (28.3–33.1 eV). Our theoretical analysis confirms that the observed chiral response originates from subfemtosecond electron dynamics driven by the magnetic component of the driving laser field. This assignment is supported by the experimental observation of a strong intensity dependence of the chiral effects and its agreement with theory. We moreover report and explain a pronounced variation of the signal strength and dichroism with the driving-field ellipticities and harmonic orders. Finally, we demonstrate the sensitivity of the experimental observables to the shape of the electron hole. This technique for chiral discrimination will yield femtosecond temporal resolution when integrated in a pump-probe scheme and subfemtosecond resolution on chiral charge migration in a self-probing scheme."}],"issue":"3","type":"journal_article","oa_version":"Published Version","title":"Chiral discrimination through bielliptical high-harmonic spectroscopy","status":"public","intvolume":" 8","_id":"14003","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"07","publication_identifier":{"eissn":["2160-3308"]},"language":[{"iso":"eng"}],"doi":"10.1103/physrevx.8.031060","quality_controlled":"1","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1103/PhysRevX.8.031060"}],"oa":1,"extern":"1","article_number":"031060","date_created":"2023-08-10T06:34:48Z","date_updated":"2023-08-22T07:42:07Z","volume":8,"author":[{"id":"71b4d059-2a03-11ee-914d-dfa3beed6530","last_name":"Baykusheva","first_name":"Denitsa Rangelova","full_name":"Baykusheva, Denitsa Rangelova"},{"full_name":"Wörner, Hans Jakob","first_name":"Hans Jakob","last_name":"Wörner"}],"publication_status":"published","publisher":"American Physical Society","year":"2018"},{"publication_status":"published","publisher":"Springer","department":[{"_id":"UlWa"}],"year":"2018","date_updated":"2023-08-24T14:39:32Z","date_created":"2018-12-11T11:46:27Z","volume":10692,"author":[{"full_name":"Fulek, Radoslav","orcid":"0000-0001-8485-1774","id":"39F3FFE4-F248-11E8-B48F-1D18A9856A87","last_name":"Fulek","first_name":"Radoslav"},{"full_name":"Pach, János","first_name":"János","last_name":"Pach"}],"related_material":{"record":[{"id":"5857","status":"public","relation":"later_version"}]},"publist_id":"7390","quality_controlled":"1","oa":1,"external_id":{"arxiv":["1708.08037"]},"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1708.08037"}],"language":[{"iso":"eng"}],"conference":{"name":"GD 2017: Graph Drawing and Network Visualization","location":"Boston, MA, United States","start_date":"201-09-25","end_date":"2017-09-27"},"doi":"10.1007/978-3-319-73915-1_14","month":"01","title":"Thrackles: An improved upper bound","status":"public","intvolume":" 10692","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"433","oa_version":"Submitted Version","alternative_title":["LNCS"],"type":"conference","abstract":[{"lang":"eng","text":"A thrackle is a graph drawn in the plane so that every pair of its edges meet exactly once: either at a common end vertex or in a proper crossing.

However, biases in discovery and reporting of inversions make it difficult to assess their prevalence and biological importance. Here, we use an approach based on linkage disequilibrium among markers genotyped for samples collected across a transect between contrasting habitats to detect chromosomal rearrangements de novo. We report 17 polymorphic rearrangements in a single locality for the coastal marine snail, Littorina saxatilis. Patterns of diversity in the field and of recombination in controlled crosses provide strong evidence that at least the majority of these rearrangements are inversions. Most show clinal changes in frequency between habitats, suggestive of divergent selection, but only one appears to be fixed for different arrangements in the two habitats. Consistent with widespread evidence for balancing selection on inversion polymorphisms, we argue that a combination of heterosis and divergent selection can explain the observed patterns and should be considered in other systems spanning environmental gradients."}],"status":"public","title":"Data from: Multiple chromosomal rearrangements in a hybrid zone between Littorina saxatilis ecotypes","department":[{"_id":"NiBa"}],"publisher":"Dryad","user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","_id":"9837","year":"2018","date_updated":"2023-08-24T14:50:26Z","date_created":"2021-08-09T12:46:39Z","oa_version":"Published Version","author":[{"first_name":"Rui","last_name":"Faria","full_name":"Faria, Rui"},{"last_name":"Chaube","first_name":"Pragya","full_name":"Chaube, Pragya"},{"first_name":"Hernán E.","last_name":"Morales","full_name":"Morales, Hernán E."},{"first_name":"Tomas","last_name":"Larsson","full_name":"Larsson, Tomas"},{"full_name":"Lemmon, Alan R.","first_name":"Alan R.","last_name":"Lemmon"},{"last_name":"Lemmon","first_name":"Emily M.","full_name":"Lemmon, Emily M."},{"last_name":"Rafajlović","first_name":"Marina","full_name":"Rafajlović, Marina"},{"full_name":"Panova, Marina","first_name":"Marina","last_name":"Panova"},{"full_name":"Ravinet, Mark","first_name":"Mark","last_name":"Ravinet"},{"full_name":"Johannesson, Kerstin","first_name":"Kerstin","last_name":"Johannesson"},{"full_name":"Westram, Anja M","orcid":"0000-0003-1050-4969","id":"3C147470-F248-11E8-B48F-1D18A9856A87","last_name":"Westram","first_name":"Anja M"},{"first_name":"Roger K.","last_name":"Butlin","full_name":"Butlin, Roger K."}],"related_material":{"record":[{"status":"public","relation":"used_in_publication","id":"6095"}]}},{"has_accepted_license":"1","publication_identifier":{"issn":["2664-1690"]},"month":"11","day":"11","scopus_import":1,"date_published":"2018-11-11T00:00:00Z","language":[{"iso":"eng"}],"oa":1,"citation":{"mla":"Anonymous, 1, et al.

Previous approaches for this problem could only handle nonnegative bounded costs. However, in many scenarios, such as queuing networks or analysis of cryptocurrency protocols, both positive and negative costs are necessary and the costs are unbounded as well.\r\n\r\nIn this work, we present a sound and efficient approach to obtain polynomial bounds on the expected accumulated cost of nondeterministic probabilistic programs. Our approach can handle (a) general positive and negative costs with bounded updates in variables; and (b) nonnegative costs with general updates to variables. We show that several natural examples which could not be handled by previous approaches are captured in our framework.\r\n\r\nMoreover, our approach leads to an efficient polynomial-time algorithm, while no previous approach for cost analysis of probabilistic programs could guarantee polynomial runtime. Finally, we show the effectiveness of our approach by presenting experimental results on a variety of programs, motivated by real-world applications, for which we efficiently synthesize tight resource-usage bounds.","lang":"eng"}],"file_date_updated":"2020-07-14T12:47:00Z","type":"technical_report","alternative_title":["IST Austria Technical Report"],"pubrep_id":"1066","related_material":{"record":[{"status":"public","relation":"later_version","id":"6175"}]},"author":[{"last_name":"Anonymous","first_name":"1","full_name":"Anonymous, 1"},{"full_name":"Anonymous, 2","first_name":"2","last_name":"Anonymous"},{"last_name":"Anonymous","first_name":"3","full_name":"Anonymous, 3"},{"full_name":"Anonymous, 4","first_name":"4","last_name":"Anonymous"},{"first_name":"5","last_name":"Anonymous","full_name":"Anonymous, 5"},{"full_name":"Anonymous, 6","last_name":"Anonymous","first_name":"6"}],"oa_version":"Published Version","file":[{"checksum":"ba3adafd36fe200385ccda583063b9eb","date_updated":"2020-07-14T12:47:00Z","date_created":"2018-12-12T11:53:32Z","relation":"main_file","file_id":"5493","content_type":"application/pdf","file_size":4202966,"creator":"system","access_level":"open_access","file_name":"IST-2018-1066-v1+1_techreport.pdf"},{"file_name":"authors-names.txt","access_level":"closed","creator":"dernst","content_type":"text/plain","file_size":322,"file_id":"6402","relation":"main_file","date_created":"2019-05-10T13:22:12Z","date_updated":"2020-07-14T12:47:00Z","checksum":"6cf3a19164bb8e5048a9c8c84dfd9fa3"}],"date_created":"2018-12-12T11:39:26Z","date_updated":"2023-08-25T08:07:48Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"5457","year":"2018","publisher":"IST Austria","title":"Cost analysis of nondeterministic probabilistic programs","ddc":["000"],"status":"public","publication_status":"published"}]
