Typically studied as largely parallel pathways, they are now increasingly recognized as interconnected networks whose activities converge at multiple regulatory levels. Recent advances in live imaging, biosensors, optogenetics, and structural approaches have revealed that auxin can rapidly trigger Ca2+ influx from the apoplast via TRANSPORT INHIBITOR RESPONSE1 (TIR1)/AUXIN-SIGNALING F-BOX (AFB)-dependent signaling mechanisms and Ca2+ channels, presumably involving cyclic nucleotides produced by TIR1/AFB auxin receptors. Conversely, Ca2+ signals arising from mechanosensing, wounding, and environmental stress can modulate auxin transport, signaling, and transcriptional outputs. Together, these discoveries highlight a dynamic, reciprocal signaling axis where Ca2+ acts both downstream and upstream of auxin to shape growth, development, tropisms, and regeneration.","lang":"eng"}],"status":"public","publication_status":"epub_ahead","date_published":"2026-09-04T00:00:00Z","article_processing_charge":"No","language":[{"iso":"eng"}],"article_type":"original","corr_author":"1","quality_controlled":"1","day":"04","_id":"22927","type":"journal_article","oa":1,"tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"OA_type":"hybrid","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2026-09-13T22:01:56Z","researchdata_availability":"no","keyword":["auxin","calcium","rapid signaling","crosstalk","growth regulation","cyclic nucleotides"],"month":"09","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1016/j.tplants.2026.08.002"}],"scopus_import":"1","date_updated":"2026-09-17T07:42:27Z","doi":"10.1016/j.tplants.2026.08.002","external_id":{"pmid":["42692943"]},"pmid":1,"OA_place":"publisher","publisher":"Cell Press","department":[{"_id":"JiFr"}],"year":"2026","citation":{"mla":"Zupunski, Milan, et al. “Decoding Dialog: The Auxin–Calcium Signaling Crosstalk in Plants.” <i>Trends in Plant Science</i>, Cell Press, 2026, doi:<a href=\"https://doi.org/10.1016/j.tplants.2026.08.002\">10.1016/j.tplants.2026.08.002</a>.","apa":"Zupunski, M., Grossmann, G., &#38; Friml, J.

In particular, existing algorithms that use VC-dimension [Ducoffe, Habib, Viennot; SICOMP 2022] [Le, Wulff-Nilsen; SODA 2024] [Chan, Chang, Gao, Le, Kisfaludi-Bak, Zheng; FOCS 2025] work with small integer weights, but do not naturally generalize to real weights.

In turn-based games, two players move a token along the edges of the graph, and the right to move the token is determined by the current vertex. In traditional bidding games - referred to as pure bidding games - the right to move the token is determined at each step through bidding; here we consider Richman bidding, where the winning player of a bid pays the losing player. The winner is decided based on a temporal or quantitative specification evaluated over the resulting infinite play.\r\nIn this work, we combine turn-based games and pure bidding games into generalized bidding games, with player-1 vertices, player-2 vertices, and bidding vertices. This natural and simple generalization of bidding games has far-reaching consequences. First, we show that, as a model, generalized bidding games are more expressive than pure bidding games, and we provide several applications. Second, and most importantly, we show that generalized Richman bidding games are structurally equivalent to simple stochastic games, a well-studied model: they are linearly interreducible to each other. As was previously known, the special case of pure Richman bidding games corresponds to random-turn games. In other words, generalized bidding games extend pure bidding games in the same way that simple stochastic games extend random-turn games. We use this connection to solve generalized Richman bidding games for temporal (parity) and quantitative (mean-payoff and discounted-sum) specifications. From a computational perspective, we establish that generalized bidding games with parity and mean-payoff specifications retain the best known upper bounds for turn-based games and pure bidding games, namely NP∩coNP.\r\nFinally, we study a repair problem that asks whether bidding vertices can be assigned \"owners\" so as to bring the threshold budget required to win the game below a given target. This problem has direct applications in compositional policy synthesis for multi-objective settings, and we show it to be NP-complete.","lang":"eng"}],"publication_status":"published","language":[{"iso":"eng"}],"article_number":"13:1-13:20","alternative_title":["LIPIcs"]},{"das_tickbox":"0","publication_identifier":{"eissn":["1868-8969"],"isbn":["9783959774475"]},"acknowledgement":"The research was partially supported by Austrian Science Fund (FWF) 10.55776/COE12,\r\nERC CoG 863818 (ForM-SMArt), FWF-2022-SFB F8502 (SPyCoDe), and ERC-2020-AdG 101020093\r\n(VAMOS) grants.","ddc":["000"],"file_date_updated":"2026-09-17T09:50:00Z","publication":"37th International Conference on Concurrency Theory","author":[{"id":"02d96aae-000e-11ec-b801-cadd0a5eefbb","last_name":"Asadi","full_name":"Asadi, Ali","first_name":"Ali"},{"full_name":"Chatterjee, Krishnendu","orcid":"0000-0002-4561-241X","first_name":"Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","last_name":"Chatterjee"},{"full_name":"Kebis, Pavol","first_name":"Pavol","last_name":"Kebis","id":"2e0132b3-4e98-11ef-b275-cf7281c2802a"}],"file":[{"file_size":959234,"date_created":"2026-09-17T09:50:00Z","file_name":"2026_LIPIcsCONCUR_Asadi2.pdf","creator":"dernst","relation":"main_file","file_id":"22947","date_updated":"2026-09-17T09:50:00Z","content_type":"application/pdf","success":1,"checksum":"2e6c55b65d9d7ce436a6f59e81d7ba17","access_level":"open_access"}],"project":[{"name":"Bilateral Artificial Intelligence (Chatterjee)","grant_number":"COE12","_id":"4029cfc7-b034-11f1-9e55-88ab2ff3b6ee"},{"_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","call_identifier":"H2020","grant_number":"863818","name":"Formal Methods for Stochastic Models: Algorithms and Applications"},{"grant_number":"F8502","name":"Interface Theory for Security and Privacy","_id":"34a1b658-11ca-11ed-8bc3-c75229f0241e"},{"call_identifier":"H2020","_id":"62781420-2b32-11ec-9570-8d9b63373d4d","name":"Vigilant Algorithmic Monitoring of Software","grant_number":"101020093"}],"fulldoi":"https://doi.org/10.4230/LIPIcs.CONCUR.2026.12","conference":{"location":"Liverpool, United Kingdom","start_date":"2026-09-01","end_date":"2026-09-04","name":"CONCUR: Conference on Concurrency Theory"},"title":"PAC learning in turn-based stochastic games with reachability objectives: A decentralized private approach via expected conditional distance","volume":391,"publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","department":[{"_id":"GradSch"},{"_id":"KrCh"},{"_id":"ToHe"}],"year":"2026","citation":{"short":"A.

This difficulty also holds in turn-based stochastic games (TBSGs), where two adversarial players interact on a finite state space. In this work, we consider turn-based stochastic games with reachability objectives. For such settings, adversarial learning, in which players are adversarial even in the learning phase, is impossible. Therefore, the goal is to consider learning, in which both players learn the unknown model together. In this spirit, previous literature on PAC learning in TBSGs considers (a) public information shared by both players; and (b) centralized learning, which means that players share the same learning algorithm. In this work, our contribution is two-fold. First, we relax these strong assumptions and ensure learning: (i) with private information not shared with the other player; and (ii) decentralized learning where the players do not share the same learning algorithm. To the best of our knowledge, this work is the first positive result for decentralized and private information learning of TBSGs with reachability objectives. Second, we introduce a game-theoretic generalization of the Expected Conditional Distance (ECD) parameter, which measures the expected length of reaching the target set. We establish a polynomial-sample complexity bound with respect to the number of states, actions, ECD parameter, and inverses of error tolerance and failure probability."}],"supplementarymaterial":"yes","has_accepted_license":"1","date_published":"2026-08-24T00:00:00Z","article_processing_charge":"Yes","oa_version":"Published Version"},{"article_processing_charge":"Yes","has_accepted_license":"1","publication_status":"published","supplementarymaterial":"yes","abstract":[{"text":"Given a weighted digraph G, a (t,g,μ)-DAG cover is a collection of g dominating DAGs D_1,… ,D_g such that all distances are approximately preserved: for every pair (u,v) of vertices, min_id_{D_i}(u,v) ≤ t⋅ d_G(u,v), and the total number of non-G edges is bounded by |(∪_i D_i)⧵ G| ≤ μ.

A working-set heap is a heap that supports the x_i ← pop() operation in O(log Γ(x_i)) time where Γ(x_i) is the size of the working set: the number of elements that were pushed onto the heap while x_i was in the heap. The goal of working set heap design is to maintain the working set property while minimizing the overhead of the Push and DecreaseKey operations. On a word RAM, there exist working set heaps that support Push and DecreaseKey in amortized constant time. In this paper, we show via a simple construction that pointer machines, one of the most general and least-assuming computational models, support working set heaps that support Push in amortized constant time and DecreaseKey in inverse-Ackermann time. A by-product of this analysis is that Dijkstra’s shortest path algorithm can be near-universally optimal on a pointer machine - incurring only an additive O(m α(m)) overhead compared to the optimal running time for distance ordering, where m denotes the number of edges in the graph."}],"status":"public","supplementarymaterial":"no","has_accepted_license":"1","date_published":"2026-08-25T00:00:00Z","language":[{"iso":"eng"}],"article_number":"45:1-45:13","alternative_title":["LIPIcs"],"title":"Near-optimal working-set heaps and dijkstra on pointer machines","file":[{"file_size":792024,"file_name":"2026_LIPIcsESA_vanderHoog2.pdf","date_created":"2026-09-17T10:33:12Z","content_type":"application/pdf","file_id":"22949","creator":"dernst","relation":"main_file","date_updated":"2026-09-17T10:33:12Z","checksum":"52e7cb8881060e8f17b89cd46504f445","success":1,"access_level":"open_access"}],"fulldoi":"https://doi.org/10.4230/LIPIcs.ESA.2026.45","project":[{"call_identifier":"H2020","_id":"bd9ca328-d553-11ed-ba76-dc4f890cfe62","name":"The design and evaluation of modern fully dynamic data structures","grant_number":"101019564"}],"conference":{"start_date":"2026-08-31","end_date":"2026-09-04","name":"ESA: European Symposium on Algorithms","location":"L’Aquila, Italy"},"author":[{"last_name":"Van Der Hoog","first_name":"Ivor","full_name":"Van Der Hoog, Ivor"},{"last_name":"Iacono","first_name":"John","full_name":"Iacono, John"},{"last_name":"Rotenberg","first_name":"Eva","full_name":"Rotenberg, Eva"},{"full_name":"Rutschmann, Daniel P","first_name":"Daniel P","id":"7397d908-b582-11f0-bf73-88b902e86527","last_name":"Rutschmann"}],"publication":"34th Annual European Symposium on Algorithms","file_date_updated":"2026-09-17T10:33:12Z","acknowledgement":"Ivor van der Hoog, Eva Rotenberg, and Daniel Rutschmann thank the VILLUM Foundation\r\ngrant (VIL37507) “Efficient Recomputations for Changeful Problems” for supporting this work.\r\nDaniel Rutschmann is supported by the European Research Council (ERC) under the European\r\nUnion’s Horizon 2020 research and innovation programme (No. 101019564) .

Although these systems operate in distinct biological contexts and produce diverse downstream outcomes, they share a conserved structural architecture and mechanism of guide‐dependent target recognition. Here, we argue that Argonautes function as programmable surveillance platforms that kinetically sample nucleic acids, engage targets through sequential pairing and conformational checkpoints, and couple recognition to functional outputs through regulated structural transitions. Rather than representing distinct recognition mechanisms, the diverse targeting behaviours observed across Argonaute families reflect different implementations of this shared framework, in which guide biogenesis, target accessibility, pairing requirements and effector coupling are weighted differently according to biological context. Viewing Argonautes through this common operational logic reconciles apparent differences in specificity, mismatch tolerance and target selection across systems, while providing a unified conceptual framework for understanding their evolution and guiding the engineering of programmable nucleic‐acid recognition technologies."}],"date_published":"2026-09-08T00:00:00Z","article_processing_charge":"Yes (via OA deal)","article_number":"1873-3468.70450","article_type":"original","language":[{"iso":"eng"}],"corr_author":"1","quality_controlled":"1","PlanS_conform":"1","day":"08","_id":"22941","type":"journal_article","oa":1,"tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"OA_type":"hybrid","researchdata_availability":"no","date_created":"2026-09-17T09:31:02Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1002/1873-3468.70450"}],"month":"09","scopus_import":"1","date_updated":"2026-09-17T11:48:51Z","doi":"10.1002/1873-3468.70450","external_id":{"pmid":["42711859"]},"pmid":1,"OA_place":"publisher","publisher":"Wiley","department":[{"_id":"JaBr"}],"citation":{"ieee":"J.

Their quantum counterparts have recently drawn attention for exhibiting highly degenerate eigenstates at zero energy—known as zero modes—stemming from chiral symmetry. Yet, the structure and implications of these zero modes remain poorly understood. In this work, we focus on the properties of the zero mode subspace in quantum kinetically constrained models with a U(1) particle-conservation symmetry. We use the U(1) East, which lacks inversion symmetry, and the inversion-symmetric U(1) East-West models to illustrate our two main results. First, we observe that the simultaneous presence of constraints and chiral symmetry generally leads to a parametric increase in the number of zero modes due to the fragmentation of the many-body\r\nHilbert space into disconnected sectors. Second, we generalize the concept of compact localized states from single-particle physics and introduce the notion of collective bound states, a special kind of nonergodic eigenstates that are robust to enlarging the system size. We formulate sufficient criteria for their existence, arguing that the degenerate zero mode subspace plays a central role, and demonstrate bound states in both example models and in a two-dimensional model, the U(1) North-East, and in the pairflip model, a system without particle conservation. Our results motivate a systematic study of bound states and their relation to ergodicity breaking, transport, and other properties of quantum kinetically constrained\r\nmodels.

A hierarchical congestion approximator (HCA) consists of a laminar family of cuts in the graph and has numerous applications in approximating cut and flow problems in graphs, designing efficient routing schemes, and managing distributed networks.\r\nThere is a tradeoff between the running time for computing an HCA and its approximation quality. The best polynomial-time construction in an n-node graph gives an HCA with approximation quality O(log1.5n loglogn). Among near-linear time algorithms, the best previous result achieves approximation quality O(log4 n). We improve upon the latter result by giving the first near-linear time algorithm for computing an HCA with approximation quality O(log2 n loglogn). Additionally, our algorithm can be implemented in the parallel setting with polylogarithmic span and near-linear work, achieving the same approximation quality. This improves upon the best previous such algorithm, which has an O(log9n) approximation quality. We also present a lower bound of Ω(logn) for the approximation guarantee of hierarchical congestion approximators.\r\nCrucial for achieving a near-linear running time is a new partitioning routine that, unlike previous such routines, manages to avoid recursing on large subgraphs. To achieve the improved approximation quality, we introduce the new concept of border routability of a cut and provide an improved sparsest cut oracle for general vertex weights."}],"status":"public","date_published":"2026-06-09T00:00:00Z","OA_type":"gold","arxiv":1,"tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"month":"06","researchdata_availability":"no","date_created":"2026-07-05T22:01:36Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","keyword":["Congestion Approximators","Hierarchical Graph Decompositions"],"_id":"22245","day":"09","type":"conference","corr_author":"1","quality_controlled":"1","oa":1,"OA_place":"publisher","department":[{"_id":"MoHe"}],"citation":{"ieee":"M.

Recent years have shown\r\nthat such systems can exhibit discriminatory behaviour against individuals and\r\nsocial groups alike, thereby amplifying existing biases and entrenching\r\nsocio-economic disparities over time. Algorithmic fairness addresses this\r\nproblem by developing methods to quantify and mitigate unfair behaviour.\r\nHowever, much of the existing literature studies fairness in a static\r\npre-deployment setting and, therefore, neglects that automated decision-makers are\r\noften deployed in dynamic environments, where their behaviour and the\r\npopulations they affect may change over time.\r\n\r\nThis thesis addresses this gap through the lens of runtime verification.\r\nInstead of treating fairness as a property of a classifier together with a fixed\r\ninput distribution, it reframes fairness as a property of the interaction trace\r\nbetween the decision-maker and its deployment environment. To evaluate such\r\nsequential fairness properties, the thesis develops runtime monitors that\r\nobserve the evolving interaction between the system and the environment and\r\nissue verdicts after each new observation. Because, these monitors are designed to detect\r\nunfair behaviour during deployment, they complement fair training,\r\nauditing, verification, and enforcement by providing an additional layer of mathematically rigorous fairness assurance.\r\n\r\nIn summary, the thesis develops quantitative, trace-based analogues of\r\nclassical group and individual fairness measures and constructs monitors for\r\nthem.

Here, we develop a modular inverse-design framework for bistable nanostructures whose function is controlled by an energy profile along a geometric reaction coordinate. Inspired by proteins with rigid domains connected by flexible hinges, we introduce a hinge-arm paradigm in which a small bistable hinge controls the energetics of a conformational transition, while rigid arms map this transition onto the separation between external binding sites. Specifically, we ask which features of a target energy profile can be programmed under different design constraints. We find that the energy barriers and the binding-site separations in the two metastable states can be readily designed, while controlling the location of the transition state or the full shape of the energy profile requires additional design freedom. Using a differentiable design framework, we find that some optimized solutions are numerically inexact but still display the functional behavior for which the target profile was selected, emphasizing the importance of function-based evaluation criteria. These results establish a practical hierarchy of designability for bistable nanostructures and provide a route toward synthetic nanomachines that couple conformational transitions to target behavior."}],"date_published":"2026-06-30T00:00:00Z","language":[{"iso":"eng"}],"type":"preprint","_id":"22893","day":"30","corr_author":"1","oa":1,"OA_type":"green","arxiv":1,"tmp":{"short":"CC BY-NC-ND (4.0)","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","image":"/images/cc_by_nc_nd.png"},"month":"06","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2606.31620"}],"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","date_created":"2026-09-09T13:19:13Z","doi":"10.48550/arXiv.2606.31620","date_updated":"2026-09-18T11:28:28Z","external_id":{"arxiv":["2606.31620"]},"OA_place":"repository","department":[{"_id":"CaGo"},{"_id":"EdHa"},{"_id":"AnSa"}],"year":"2026","citation":{"apa":"Ehrmann, A., Krstić, M., Samadzadeh, S., &#38; Goodrich, C.

However, designing similar energy-delivery schemes from the bottom up, essential for the development of powered nanostructures and other \\emph{de novo} machinery, presents a significant challenge: how can an energy-rich structure be stable in solution yet still deliver this energy at precisely the right time? In this paper, we present a purely physical mechanism that solves this challenge, facilitating energy transfer akin to ATP hydrolysis, yet occurring between synthetic nanostructures without any biochemical interactions. This targeted energy delivery is achieved by exploiting a differentiable state-based model to balance the energy profiles that govern the structural transitions in the two nanostructures, creating a coupled relaxation pathway with minimal barriers that facilitates energy delivery. We verify the effectiveness and robustness of this mechanism through Langevin Dynamics simulations, demonstrating that a bath of the high-energy structures can systematically and repeatedly drive the target structure out of equilibrium, enabling it to perform tasks. As the mechanism operates only through explicit physical forces without any biochemistry or internal state variables, our results present generic and far-reaching design principles, setting the stage for the next generation of synthetic nanomachines.","lang":"eng"}],"status":"public","publication_status":"draft","article_processing_charge":"No","language":[{"iso":"eng"}]},{"language":[{"iso":"eng"}],"has_accepted_license":"1","status":"public","abstract":[{"text":"Large-scale deep learning models are known to memorize parts of the training\r\nset.

Their true nature remains unclear though, and their evolutionary connection to their lower-redshift counterparts is still poorly constrained. Thus, we present WISEA J123635.56+621424.2 (here dubbed the Saguaro), a z = 2.0145 galaxy in GOODS-North, as a possible analog of high-redshift LRDs and a potential missing link in their evolutionary path toward lower-redshift systems. It features a compact LRD-like nucleus surrounded by a face-on spiral host. Its connections to LRDs include the following: (1) its nuclear spectrum shows a clear “V-shaped” SED, and (2) when redshifted to z = 7, surface brightness dimming makes the host undetectable, thus mimicking an LRD. This suggests that high-redshift LRDs may be embedded in extended hosts. To test this, we stack rest-frame UV images of 99 photometrically selected LRDs, revealing faint, diffuse emission. Stacking in redshift bins reveals mild radial growth, consistent with the expected galaxy size evolution. A simple analytic model confirms that surface brightness dimming alone can explain their compact appearance. Lastly, we show that the Saguaro is not unique by describing similar objects from the literature at z ≲ 3.5. Taken together, our results support a scenario in which LRDs may not be a distinct population, but could be the visible nuclei of galaxies undergoing a short-lived, (perhaps) AGN-dominated evolutionary phase, with their compact, red appearance driven largely by observational biases.","lang":"eng"}],"has_accepted_license":"1","supplementarymaterial":"yes","status":"public","publication_status":"published","article_processing_charge":"Yes","article_number":"205","language":[{"iso":"eng"}],"article_type":"original","quality_controlled":"1","PlanS_conform":"1","type":"journal_article","_id":"22950","day":"29","DOAJ_listed":"1","oa":1,"tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"dataavailabilitystatement":"Facilities: CXO - Chandra X-ray Observatory satellite, HST - Hubble Space Telescope satellite, JWST - James Webb Space Telescope.\r\n\r\nSoftware: Astropy (Astropy Collaboration et al. 2022), Bagpipes (A.

Localisation measures such as discounted averages offer a principled middle ground, yet remain poorly understood in runtime verification. This paper studies discounted sums from a monitoring perspective, in both deterministic and stochastic settings. We formalize the discounted monitoring problem and show that exact, sound monitoring of discounted sums cannot be achieved with finite memory. To overcome this impossibility, we introduce ε-approximately sound monitoring, deriving explicit bounds on memory and observation requirements. We then extend the framework to stochastic processes via expected discounted sums, defining pointwise and uniform (ε,δ)-soundness notions, establishing statistical optimality, and proving impossibility beyond a precision threshold. We also formalize the resource complexity of deterministic discounted monitoring via affine register machines and prove a tight worst-case lower bound. Finally, we present a specification language for arithmetic expressions over multiple discounted sums with synchronous and asynchronous semantics, and evaluate our approach on practical scenarios including algorithmic fairness.","lang":"eng"}],"publication_status":"published","status":"public","date_published":"2026-08-24T00:00:00Z","oa_version":"Published Version","alternative_title":["LIPIcs"],"language":[{"iso":"eng"}],"article_number":"22:1-22:19","oa":1,"_id":"22921","type":"conference","day":"24","quality_controlled":"1","corr_author":"1","month":"08","intvolume":"       391","date_created":"2026-09-13T22:01:54Z","researchdata_availability":"no","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","keyword":["Runtime Verification","Probabilistic Systems","Quantitative Verification","Approximate Monitoring"],"OA_type":"gold","tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"dataavailabilitystatement":"Software (Source Code): https://github.com/filipcano/monitoringdiscounted-sum-properties [10]\r\narchived at swh:1:dir:cb99396415f279c985cd05206b44320227f64245\r\n","arxiv":1}]
