It is known that the straight skeleton of a simple polygon is a tree, and one can naturally derive directions on the edges of the tree from the propagation of the shrinking process. In this paper, we ask the reverse question: Given a tree with directed edges, can it be the straight skeleton of a polygon? And if so, can we find a suitable simple polygon?

In this work, we study frequency LTL (fLTL), an extension of LTL which allows to speak about frequencies of events along an execution. Such an extension is particularly useful for probabilistic systems that often cannot fulfil strict qualitative guarantees on the behaviour. It has been recently shown that controller synthesis for Markov decision processes and fLTL is decidable when all the bounds on frequencies are 1. As a step towards a complete quantitative solution, we show that the problem is decidable for the fragment fLTL\\GU, where U does not occur in the scope of G (but still F can). Our solution is based on a novel translation of such quantitative formulae into equivalent deterministic automata.","lang":"eng"}],"month":"11","intvolume":" 9450","scopus_import":1,"alternative_title":["LNCS"],"date_updated":"2021-01-12T06:51:50Z","department":[{"_id":"ToHe"},{"_id":"KrCh"}],"_id":"1594","status":"public","type":"conference","conference":{"location":"Suva, Fiji","end_date":"2015-11-28","start_date":"2015-11-24","name":"LPAR: Logic for Programming, Artificial Intelligence, and Reasoning"}},{"_id":"1596","status":"public","pubrep_id":"595","type":"book_chapter","conference":{"name":"GD: Graph Drawing and Network Visualization","location":"Los Angeles, CA, United States","end_date":"2015-09-26","start_date":"2015-09-24"},"ddc":["510"],"date_updated":"2022-01-28T09:20:50Z","department":[{"_id":"UlWa"}],"file_date_updated":"2020-07-14T12:45:04Z","oa_version":"Submitted Version","abstract":[{"lang":"eng","text":"Let C={C1,...,Cn} denote a collection of translates of a regular convex k-gon in the plane with the stacking order.

Our aim is to simplify the interaction of tools, helping the research community to build upon other people’s work. A key feature of the format is the use of very generic acceptance conditions, specified by Boolean combinations of acceptance primitives, rather than being limited to common cases such as Büchi, Streett, or Rabin. Such flexibility in the choice of acceptance conditions can be exploited in applications, for example in probabilistic model checking, and furthermore encourages the development of acceptance-agnostic tools for automata manipulations.

The development tools include hybrid systems reachability analysis tools, model-based development environments like Simulink/Stateflow (SLSF), etc. First, hybrid automaton models are randomly generated. Next, these hybrid automaton models are translated to a number of different tools (currently, SpaceEx, dReach, Flow*, HyCreate, and the MathWorks’ Simulink/Stateflow) using the HyST source transformation and translation tool. Then, the hybrid automaton models are executed in the different tools and their outputs are parsed. The final step is the differential comparison: the outputs of the different tools are compared. If the results do not agree (in the sense that an analysis or verification result from one tool does not match that of another tool, ignoring timeouts, etc.), a candidate bug is flagged and the model is saved for future analysis by the user. The process then repeats and the monitoring continues until the user terminates the process. We present preliminary results that have been useful in identifying a few bugs in the analysis methods of different development tools, and in an earlier version of HyST."}],"month":"11","intvolume":" 9333","alternative_title":["LNCS"],"scopus_import":"1","date_updated":"2022-02-01T14:52:59Z","department":[{"_id":"ToHe"}],"_id":"1606","status":"public","type":"conference","conference":{"start_date":"2015-09-22","location":"Vienna, Austria","end_date":"2015-09-25","name":"RV: Runtime Verification"},"day":"15","publication":"6th International Conference","year":"2015","doi":"10.1007/978-3-319-23820-3_19","date_published":"2015-11-15T00:00:00Z","date_created":"2018-12-11T11:52:59Z","page":"281 - 286","quality_controlled":"1","publisher":"Springer Nature","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","citation":{"chicago":"Nguyen, Luan, Christian Schilling, Sergiy Bogomolov, and Taylor Johnson. “Runtime Verification for Hybrid Analysis Tools.” In 6th International Conference, 9333:281–86.

In the traditional setting, the system is “constructed from scratch” rather than composed from reusable components. However, this is rare in practice, and almost every non-trivial software system relies heavily on the use of libraries of reusable components. Recently, Lustig and Vardi introduced dataflow and controlflow synthesis from libraries of reusable components. They proved that dataflow synthesis is undecidable, while controlflow synthesis is decidable. The problem of controlflow synthesis from libraries of probabilistic components was considered by Nain, Lustig and Vardi, and was shown to be decidable for qualitative analysis (that asks that the specification be satisfied with probability 1). Our main contribution for controlflow synthesis from probabilistic components is to establish better complexity bounds for the qualitative analysis problem, and to show that the more general quantitative problem is undecidable. For the qualitative analysis, we show that the problem (i) is EXPTIME-complete when the specification is given as a deterministic parity word automaton, improving the previously known 2EXPTIME upper bound; and (ii) belongs to UP ∩ coUP and is parity-games hard, when the specification is given directly as a parity condition on the components, improving the previously known EXPTIME upper bound."}],"oa_version":"Preprint","scopus_import":"1","alternative_title":["LNCS"],"main_file_link":[{"open_access":"1","url":"http://arxiv.org/abs/1502.04844"}],"month":"06","intvolume":" 9135","date_updated":"2022-02-01T15:04:44Z","department":[{"_id":"KrCh"}],"_id":"1609","type":"conference","conference":{"location":"Kyoto, Japan","end_date":"2015-07-10","start_date":"2015-07-06","name":"ICALP: Automata, Languages and Programming"},"status":"public","year":"2015","day":"20","publication":"42nd International Colloquium","page":"108 - 120","date_published":"2015-06-20T00:00:00Z","doi":"10.1007/978-3-662-47666-6_9","date_created":"2018-12-11T11:53:00Z","acknowledgement":"This research was supported by Austrian Science Fund (FWF) Grant No P23499- N23, FWF NFN Grant No S11407-N23 (SHiNE), ERC Start grant (279307: Graph Games), EU FP7 Project Cassting, NSF grants CNS 1049862 and CCF-1139011, by NSF Expeditions in Computing project “ExCAPE: Expeditions in Computer Augmented Program Engineering”, by BSF grant 9800096, and by gift from Intel.","publisher":"Springer Nature","quality_controlled":"1","oa":1,"citation":{"ieee":"K.

Interestingly, these subtle synaptic changes are accompanied by pronounced perturbations of γ-oscillatory network activity, which has been implicated in cognitive function and is altered in multiple psychiatric and neurodevelopmental disorders.

It is generally assumed that the output of one PII to its target cells is strong and rapid. Here, we show that, unexpectedly, both strength and time course of PII-mediated perisomatic inhibition change with distance between synaptically connected partners in the rodent hippocampus. Synaptic signals become weaker due to lower contact numbers and decay more slowly with distance, very likely resulting from changes in GABAA receptor subunit composition. When distance-dependent synaptic inhibition is introduced to a rhythmically active neuronal network model, randomly driven principal cell assemblies are strongly synchronized by the PIIs, leading to higher precision in principal cell spike times than in a network with uniform synaptic inhibition.

Construction of genetically encoded biosensors generally relies on the availability of a binding "core" that is both specific and stable, which can then be combined with fluorescent molecules to create a sensor. However, binding proteins with the desired properties are often not available in nature and substantial improvement to sensors can be required, particularly with regard to their durability. Ancestral protein reconstruction is a powerful protein-engineering tool able to generate highly stable and functional proteins. In this work, we sought to establish the utility of ancestral protein reconstruction to biosensor development, beginning with the construction of an l-arginine biosensor. l-arginine, as the immediate precursor to nitric oxide, is an important molecule in many physiological contexts including brain function. Using a combination of ancestral reconstruction and circular permutation, we constructed a Förster resonance energy transfer (FRET) biosensor for l-arginine (cpFLIPR). cpFLIPR displays high sensitivity and specificity, with a Kd of ∼14 μM and a maximal dynamic range of 35%. Importantly, cpFLIPR was highly robust, enabling accurate l-arginine measurement at physiological temperatures. We established that cpFLIPR is compatible with two-photon excitation fluorescence microscopy and report l-arginine concentrations in brain tissue.","lang":"eng"}],"pmid":1,"oa_version":"Submitted Version","scopus_import":1,"main_file_link":[{"open_access":"1","url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4570536/"}],"month":"09","intvolume":" 24","publication_status":"published","language":[{"iso":"eng"}],"volume":24,"issue":"9","project":[{"grant_number":"RGY0084/2012","name":"In situ real-time imaging of neurotransmitter signaling using designer optical sensors (HFSP Young Investigator)","_id":"255BFFFA-B435-11E9-9278-68D0E5697425"}],"citation":{"chicago":"Whitfield, Jason, William Zhang, Michel Herde, Ben Clifton, Johanna Radziejewski, Harald L Janovjak, Christian Henneberger, and Colin Jackson. “Construction of a Robust and Sensitive Arginine Biosensor through Ancestral Protein Reconstruction.” Protein Science.

In a structured population, cooperators can form clusters which resist exploitation by defectors. Recently, it was observed that a shift update rule is an extremely strong amplifier of cooperation in a one dimensional spatial model. For the shift update rule, an individual is chosen for reproduction proportional to fecundity; the offspring is placed next to the parent; a random individual dies. Subsequently, the population is rearranged (shifted) until all individual cells are again evenly spaced out. For large population size and a one dimensional population structure, the shift update rule favors cooperation for any benefit-to-cost ratio greater than one. But every attempt to generalize shift updating to higher dimensions while maintaining its strong effect has failed. The reason is that in two dimensions the clusters are fragmented by the movements caused by rearranging the cells. Here we introduce the natural phenomenon of a repulsive force between cells of different types. After a birth and death event, the cells are being rearranged minimizing the overall energy expenditure. If the repulsive force is sufficiently high, shift becomes a strong promoter of cooperation in two dimensions."}],"intvolume":" 5","month":"11","scopus_import":1,"language":[{"iso":"eng"}],"file":[{"date_updated":"2020-07-14T12:45:07Z","file_size":1021931,"creator":"system","date_created":"2018-12-12T10:12:29Z","file_name":"IST-2016-466-v1+1_srep17147.pdf","content_type":"application/pdf","access_level":"open_access","relation":"main_file","file_id":"4947","checksum":"38e06d8310d2087cae5f6d4d4bfe082b"}],"publication_status":"published","ec_funded":1,"volume":5,"_id":"1624","pubrep_id":"466","status":"public","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"type":"journal_article","ddc":["000"],"date_updated":"2021-01-12T06:52:05Z","department":[{"_id":"KrCh"}],"file_date_updated":"2020-07-14T12:45:07Z"},{"has_accepted_license":"1","year":"2015","day":"25","publication":"Biotechnology for Biofuels","date_published":"2015-11-25T00:00:00Z","doi":"10.1186/s13068-015-0380-2","date_created":"2018-12-11T11:53:05Z","quality_controlled":"1","publisher":"BioMed Central","oa":1,"citation":{"chicago":"Hammar, Petter, Andreas Angermayr, Staffan Sjostrom, Josefin Van Der Meer, Klaas Hellingwerf, Elton Hudson, and Hakaan Joensson. “Single-Cell Screening of Photosynthetic Growth and Lactate Production by Cyanobacteria.” Biotechnology for Biofuels.

In this work we present the first method for detailed spatio-temporal reconstruction of eyelids. Tracking and reconstructing eyelids is extremely challenging, as this region exhibits very complex and unique skin deformation where skin is folded under while opening the eye. Furthermore, eyelids are often only partially visible and obstructed due to selfocclusion and eyelashes. Our approach is to combine a geometric deformation model with image data, leveraging multi-view stereo, optical flow, contour tracking and wrinkle detection from local skin appearance. Our deformation model serves as a prior that enables reconstruction of eyelids even under strong self-occlusions caused by rolling and folding skin as the eye opens and closes. The output is a person-specific, time-varying eyelid reconstruction with anatomically plausible deformations. Our high-resolution detailed eyelids couple naturally with current facial performance capture approaches.

Our datadriven technique acquires the aerodynamic properties of an object simply by capturing its falling motion using a single camera. Once model parameters are estimated, OmniAD enables realistic realtime simulation of rigid bodies, such as the tumbling and gliding of leaves, without simulating the surrounding air.

We depart from earlier work on soap bubbles and foams by noting that their dynamics are naturally described by a Lagrangian vortex sheet model in which circulation is the primary variable. This leads us to derive a novel circulation-preserving surface-only discretization of foam dynamics driven by surface tension on a non-manifold triangle mesh. We represent the surface using a mesh-based multimaterial surface tracker which supports complex bubble topology changes, and evolve the surface according to the ambient air flow induced by a scalar circulation field stored on the mesh. Surface tension forces give rise to a simple update rule for circulation, even at non-manifold Plateau borders, based on a discrete measure of signed scalar mean curvature. We further incorporate vertex constraints to enable the interaction of soap films with wires. The result is a method that is at once simple, robust, and efficient, yet able to capture an array of soap films behaviors including foam rearrangement, catenoid collapse, blowing bubbles, and double bubbles being pulled apart."}],"oa_version":"Submitted Version","ec_funded":1,"issue":"4","volume":34,"publication_status":"published","language":[{"iso":"eng"}],"file":[{"checksum":"57b07d78d2d612a8052744b37d4a71fa","file_id":"4867","relation":"main_file","access_level":"open_access","content_type":"application/pdf","file_name":"IST-2016-608-v1+1_doublebubbles.pdf","date_created":"2018-12-12T10:11:14Z","creator":"system","file_size":8973215,"date_updated":"2020-07-14T12:45:07Z"}]},{"volume":9472,"ec_funded":1,"language":[{"iso":"eng"}],"publication_identifier":{"isbn":["978-3-662-48970-3"]},"publication_status":"published","month":"12","intvolume":" 9472","scopus_import":"1","alternative_title":["LNCS"],"main_file_link":[{"url":"http://arxiv.org/abs/1504.07067","open_access":"1"}],"oa_version":"Preprint","abstract":[{"text":"Constraint Satisfaction Problem (CSP) is a fundamental algorithmic problem that appears in many areas of Computer Science. It can be equivalently stated as computing a homomorphism R→ΓΓ between two relational structures, e.g. between two directed graphs. Analyzing its complexity has been a prominent research direction, especially for the fixed template CSPs where the right side ΓΓ is fixed and the left side R is unconstrained.\r\n\r\nFar fewer results are known for the hybrid setting that restricts both sides simultaneously. It assumes that R belongs to a certain class of relational structures (called a structural restriction in this paper). We study which structural restrictions are effective, i.e. there exists a fixed template ΓΓ (from a certain class of languages) for which the problem is tractable when R is restricted, and NP-hard otherwise. We provide a characterization for structural restrictions that are closed under inverse homomorphisms. The criterion is based on the chromatic number of a relational structure defined in this paper; it generalizes the standard chromatic number of a graph.\r\n\r\nAs our main tool, we use the algebraic machinery developed for fixed template CSPs. To apply it to our case, we introduce a new construction called a “lifted language”. We also give a characterization for structural restrictions corresponding to minor-closed families of graphs, extend results to certain Valued CSPs (namely conservative valued languages), and state implications for (valued) CSPs with ordered variables and for the maximum weight independent set problem on some restricted families of graphs.","lang":"eng"}],"department":[{"_id":"VlKo"}],"date_updated":"2022-02-01T15:12:35Z","status":"public","type":"conference","conference":{"start_date":"2015-12-09","end_date":"2015-12-11","location":"Nagoya, Japan","name":"ISAAC: International Symposium on Algorithms and Computation"},"_id":"1636","doi":"10.1007/978-3-662-48971-0_48","date_published":"2015-12-01T00:00:00Z","date_created":"2018-12-11T11:53:10Z","page":"566 - 577","day":"01","publication":"26th International Symposium","year":"2015","publisher":"Springer Nature","quality_controlled":"1","oa":1,"title":"Effectiveness of structural restrictions for hybrid CSPs","publist_id":"5519","author":[{"id":"3D50B0BA-F248-11E8-B48F-1D18A9856A87","first_name":"Vladimir","last_name":"Kolmogorov","full_name":"Kolmogorov, Vladimir"},{"full_name":"Rolinek, Michal","last_name":"Rolinek","id":"3CB3BC06-F248-11E8-B48F-1D18A9856A87","first_name":"Michal"},{"last_name":"Takhanov","full_name":"Takhanov, Rustem","first_name":"Rustem"}],"external_id":{"arxiv":["1504.07067"]},"article_processing_charge":"No","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","citation":{"ieee":"V.

Previous methods have used stream function techniques for the simulation of detailed single-phase flows, but a formulation for liquid simulation has proved elusive in part due to the free surface boundary conditions. In this paper, we introduce a stream function approach to liquid simulations with novel boundary conditions for free surfaces, solid obstacles, and solid-fluid coupling.\r\n\r\nAlthough our approach increases the dimension of the linear system necessary to enforce incompressibility, it provides interesting and surprising benefits. First, the resulting flow is guaranteed to be divergence-free regardless of the accuracy of the solve. Second, our free-surface boundary conditions guarantee divergence-free motion even in the un-simulated air phase, which enables two-phase flow simulation by only computing a single phase. We implemented this method using a variant of FLIP simulation which only samples particles within a narrow band of the liquid surface, and we illustrate the effectiveness of our method for detailed two-phase flow simulations with complex boundaries, detailed bubble interactions, and two-way solid-fluid coupling.","lang":"eng"}],"oa_version":"Submitted Version","scopus_import":1,"alternative_title":["ACM Transactions on Graphics"],"intvolume":" 34","month":"07","date_updated":"2023-02-23T10:07:37Z","ddc":["000"],"department":[{"_id":"ChWo"}],"file_date_updated":"2020-07-14T12:45:07Z","_id":"1632","conference":{"name":"SIGGRAPH: Special Interest Group on Computer Graphics and Interactive Techniques","location":"Los Angeles, CA, USA","end_date":"2015-08-13","start_date":"2015-08-09"},"type":"conference","pubrep_id":"610","status":"public","year":"2015","has_accepted_license":"1","day":"27","date_created":"2018-12-11T11:53:09Z","doi":"10.1145/2766935","date_published":"2015-07-27T00:00:00Z","acknowledgement":"The first author was supported by a JSPS Postdoctoral Fellowship for Research Abroad.

The placement of a shape is modeled as an oriented bounding box. Simple geometric relationships between this bounding box and nearby scene polygons define a feature set for the placement. The feature sets of all example placements are then used to learn a probabilistic model over all possible placements and scenes. With this model, we can generate a new set of placements with similar geometric relationships in any given scene. We introduce extensions that enable propagation and generation of shapes in 3D scenes, as well as the application of a learned modeling session to large scenes without additional user interaction. These concepts allow us to generate complex scenes with thousands of objects with relatively little user interaction.","lang":"eng"}],"month":"07","intvolume":" 34","scopus_import":1,"file":[{"date_created":"2018-12-12T10:07:49Z","file_name":"IST-2016-576-v1+1_guerrero-2015-lsp-paper.pdf","creator":"system","date_updated":"2020-07-14T12:45:07Z","file_size":11902290,"file_id":"4647","checksum":"8b05a51e372c9b0b5af9a00098a9538b","access_level":"open_access","relation":"main_file","content_type":"application/pdf"}],"language":[{"iso":"eng"}],"publication_status":"published","issue":"4","volume":34}]
