A configuration is a state and a value for each counter; a transition changes the state and each counter is incremented, decremented, or left unchanged. While qualitative properties such as state and configuration reachability have been studied for VASS, we consider the long-run average cost of infinite computations of VASS. The cost of a configuration is for each state, a linear combination of the counter values. In the special case of uniform cost functions, the linear combination is the same for all states. The (regular) long-run emptiness problem is, given a VASS, a cost function, and a threshold value, if there is a (lasso-shaped) computation such that the long-run average value of the cost function does not exceed the threshold. For uniform cost functions, we show that the regular long-run emptiness problem is (a) decidable in polynomial time for integer-valued VASS, and (b) decidable but nonelementarily hard for natural-valued VASS (i.e., nonnegative counters). For general cost functions, we show that the problem is (c) NP-complete for integer-valued VASS, and (d) undecidable for natural-valued VASS. Our most interesting result is for (c) integer-valued VASS with general cost functions, where we establish a connection between the regular long-run emptiness problem and quadratic Diophantine inequalities. The general (nonregular) long-run emptiness problem is equally hard as the regular problem in all cases except (c), where it remains open.

There are three qualitative winning criteria, namely, sure winning, which requires all paths to satisfy the condition, almost-sure winning, which requires the condition to be satisfied with probability 1, and limit-sure winning, which requires the condition to be satisfied with probability arbitrarily close to 1. We study the combination of two of these criteria for parity conditions, e.g., there are two parity conditions one of which must be won surely, and the other almost-surely. The problem has been studied recently by Berthon et al. for MDPs with combination of sure and almost-sure winning, under infinite-memory strategies, and the problem has been established to be in NP cap co-NP. Even in MDPs there is a difference between finite-memory and infinite-memory strategies. Our main results for combination of sure and almost-sure winning are as follows: (a) we show that for MDPs with finite-memory strategies the problem is in NP cap co-NP; (b) we show that for turn-based stochastic games the problem is co-NP-complete, both for finite-memory and infinite-memory strategies; and (c) we present algorithmic results for the finite-memory case, both for MDPs and turn-based stochastic games, by reduction to non-stochastic parity games. In addition we show that all the above complexity results also carry over to combination of sure and limit-sure winning, and results for all other combinations can be derived from existing results in the literature. Thus we present a complete picture for the study of combinations of two qualitative winning criteria for parity conditions in MDPs and turn-based stochastic games.

Two well-known coding techniques have been introduced for this setting: decode-and-forward and compress-and-forward. In decode-and-forward, the relay completely decodes the message and sends some information to the destination; in compress-and-forward, the relay does not decode, and it sends a compressed version of the received signal to the destination using Wyner–Ziv coding. In this paper, we present a novel coding paradigm that provides an improved achievable rate for the primitive relay channel. The idea is to combine compress-and-forward and decode-and-forward via a chaining construction. We transmit over pairs of blocks: in the first block, we use compress-and-forward; and, in the second block, we use decode-and-forward. More specifically, in the first block, the relay does not decode, it compresses the received signal via Wyner–Ziv, and it sends only part of the compression to the destination. In the second block, the relay completely decodes the message, it sends some information to the destination, and it also sends the remaining part of the compression coming from the first block. By doing so, we are able to strictly outperform both compress-and-forward and decode-and-forward. Note that the proposed coding scheme can be implemented with polar codes. As such, it has the typical attractive properties of polar coding schemes, namely, quasi-linear encoding and decoding complexity, and error probability that decays at super-polynomial speed. As a running example, we take into account the special case of the erasure relay channel, and we provide a comparison between the rates achievable by our proposed scheme and the existing upper and lower bounds.","lang":"eng"}],"file_date_updated":"2020-07-14T12:47:47Z","department":[{"_id":"MaMo"}],"ddc":["510"],"date_updated":"2023-02-23T12:49:28Z","status":"public","article_type":"original","type":"journal_article","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)"},"_id":"7007"},{"month":"01","intvolume":" 2125","publisher":"Research Institute for Mathematical Sciences, Kyoto University","quality_controlled":"1","oa":1,"main_file_link":[{"open_access":"1","url":"http://www.kurims.kyoto-u.ac.jp/~kyodo/kokyuroku/contents/2125.html"}],"oa_version":"Submitted Version","abstract":[{"text":"The aim of this short note is to expound one particular issue that was discussed during the talk [10] given at the symposium ”Researches on isometries as preserver problems and related topics” at Kyoto RIMS. That is, the role of Dirac masses by describing the isometry group of various metric spaces of probability measures. This article is of survey character, and it does not contain any essentially new results.From an isometric point of view, in some cases, metric spaces of measures are similar to C(K)-type function spaces. Similarity means here that their isometries are driven by some nice transformations of the underlying space. Of course, it depends on the particular choice of the metric how nice these transformations should be. Sometimes, as we will see, being a homeomorphism is enough to generate an isometry. But sometimes we need more: the transformation must preserve the underlying distance as well. Statements claiming that isometries in questions are necessarily induced by homeomorphisms are called Banach-Stone-type results, while results asserting that the underlying transformation is necessarily an isometry are termed as isometric rigidity results.As Dirac masses can be considered as building bricks of the set of all Borel measures, a natural question arises:Is it enough to understand how an isometry acts on the set of Dirac masses? Does this action extend uniquely to all measures?In what follows, we will thoroughly investigate this question.","lang":"eng"}],"date_published":"2019-01-30T00:00:00Z","volume":2125,"date_created":"2019-11-18T15:39:53Z","page":"34-41","day":"30","publication":"Kyoto RIMS Kôkyûroku","language":[{"iso":"eng"}],"publication_status":"published","year":"2019","status":"public","type":"conference","conference":{"start_date":"2019-01-28","location":"Kyoto, Japan","end_date":"2019-01-30","name":"Research on isometries as preserver problems and related topics"},"_id":"7035","title":"Dirac masses and isometric rigidity","department":[{"_id":"LaEr"}],"author":[{"first_name":"Gyorgy Pal","last_name":"Geher","full_name":"Geher, Gyorgy Pal"},{"last_name":"Titkos","full_name":"Titkos, Tamas","first_name":"Tamas"},{"full_name":"Virosztek, Daniel","orcid":"0000-0003-1109-5511","last_name":"Virosztek","first_name":"Daniel","id":"48DB45DA-F248-11E8-B48F-1D18A9856A87"}],"article_processing_charge":"No","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"mla":"Geher, Gyorgy Pal, et al. “Dirac Masses and Isometric Rigidity.” Kyoto RIMS Kôkyûroku, vol. 2125, Research Institute for Mathematical Sciences, Kyoto University, 2019, pp. 34–41.","ama":"Geher GP, Titkos T, Virosztek D.

The plateletlike nature of the MSiX crystals and their extremely low residual resistivities make measurements of the resistivity along the [001] direction extremely challenging. To accomplish such measurements, microstructures of single crystals were prepared using focused ion beam techniques. Microstructures prepared in this manner have very well-defined geometries and maintain their high crystal quality, verified by the observations of quantum oscillations. We present magnetoresistance and quantum oscillation data for currents applied along both [001] and [100] in ZrSiS and ZrSiSe, which are consistent with the nontrivial topology of the Dirac line-node, as determined by a measured π Berry phase. Surprisingly, we find that, despite the three dimensional nature of both the Fermi surfaces of ZrSiS and ZrSiSe, both the resistivity anisotropy under applied magnetic fields and the in-plane angular dependent magnetoresistance differ considerably between the two compounds. Finally, we discuss the role microstructuring can play in the study of these materials and our ability to make these microstructures free-standing.","lang":"eng"}],"file_date_updated":"2020-07-14T12:47:48Z","extern":"1","ddc":["530"],"date_updated":"2021-01-12T08:11:35Z","status":"public","article_type":"original","type":"journal_article","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)"},"_id":"7055","doi":"10.1063/1.5124568","date_published":"2019-10-17T00:00:00Z","date_created":"2019-11-19T12:52:43Z","day":"17","publication":"APL Materials","has_accepted_license":"1","year":"2019","quality_controlled":"1","publisher":"AIP","oa":1,"title":"Out-of-plane transport in ZrSiS and ZrSiSe microstructures","author":[{"first_name":"Kent R.","full_name":"Shirer, Kent R.","last_name":"Shirer"},{"first_name":"Kimberly A","id":"13C26AC0-EB69-11E9-87C6-5F3BE6697425","full_name":"Modic, Kimberly A","orcid":"0000-0001-9760-3147","last_name":"Modic"},{"first_name":"Tino","last_name":"Zimmerling","full_name":"Zimmerling, Tino"},{"last_name":"Bachmann","full_name":"Bachmann, Maja D.","first_name":"Maja D."},{"first_name":"Markus","full_name":"König, Markus","last_name":"König"},{"first_name":"Philip J.

While the monoarsenides (NbAs and TaAs) have topologically distinct left and right-handed Weyl fermi surfaces, NbP is argued to be “topologically trivial” due to the fact that all pairs of Weyl nodes are encompassed by a single Fermi surface. We use torque magnetometry to measure the magnetic response of NbP up to 60 tesla and uncover a Berry paramagnetic response, characteristic of the topological Weyl nodes, across the entire field range. At the quantum limit B* (≈32 T), τ/B experiences a change in slope when the chemical potential enters the last Landau level. Our calculations confirm that this magnetic response arises from band topology of the Weyl pocket, even though the Fermi surface encompasses both Weyl nodes at zero magnetic field. We also find that the magnetic field pulls the chemical potential to the chiral n = 0 Landau level in the quantum limit, providing a disorder-free way of accessing chiral Weyl fermions in systems that are “not quite” WSMs in zero magnetic field."}],"oa_version":"Published Version","intvolume":" 9","month":"02","date_updated":"2021-01-12T08:11:36Z","ddc":["530"],"extern":"1","file_date_updated":"2020-07-14T12:47:48Z","_id":"7057","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)"},"article_type":"original","type":"journal_article","status":"public"},{"month":"09","intvolume":" 31","main_file_link":[{"url":"https://arxiv.org/abs/1905.08640","open_access":"1"}],"oa_version":"Preprint","abstract":[{"lang":"eng","text":"In the Ca1−x La x FeAs2 (1 1 2) family of pnictide superconductors, we have investigated a highly overdoped composition (x = 0.56), prepared by a high-pressure, high-temperature synthesis.

These results showcase a generic approach to manipulating electronic order on micrometer length scales in strongly correlated matter without compromising the cleanliness, stoichiometry, or mean free path.","lang":"eng"}],"oa_version":"None"},{"file_date_updated":"2020-07-14T12:47:50Z","date_updated":"2021-01-12T08:11:56Z","extern":"1","ddc":["576"],"article_type":"original","type":"journal_article","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"},"status":"public","keyword":["cardiomyocyte","cell cycle","Cofilin2","cytoskeleton","Hippo","microRNA","regeneration","YAP"],"_id":"7128","volume":27,"issue":"9","publication_identifier":{"issn":["2211-1247"]},"publication_status":"published","file":[{"content_type":"application/pdf","access_level":"open_access","relation":"main_file","checksum":"c5d855d07263bfec718673385d0ea2d7","file_id":"7129","date_updated":"2020-07-14T12:47:50Z","file_size":4650750,"creator":"rcubero","date_created":"2019-11-26T22:30:43Z","file_name":"torrini_cellreports_2019.pdf"}],"language":[{"iso":"eng"}],"month":"05","intvolume":" 27","abstract":[{"lang":"eng","text":"Loss of functional cardiomyocytes is a major determinant of heart failure after myocardial infarction. Previous high throughput screening studies have identified a few microRNAs (miRNAs) that can induce cardiomyocyte proliferation and stimulate cardiac regeneration in mice. Here, we show that all of the most effective of these miRNAs activate nuclear localization of the master transcriptional cofactor Yes-associated protein (YAP) and induce expression of YAP-responsive genes. In particular, miR-199a-3p directly targets two mRNAs coding for proteins impinging on the Hippo pathway, the upstream YAP inhibitory kinase TAOK1, and the E3 ubiquitin ligase β-TrCP, which leads to YAP degradation. Several of the pro-proliferative miRNAs (including miR-199a-3p) also inhibit filamentous actin depolymerization by targeting Cofilin2, a process that by itself activates YAP nuclear translocation. Thus, activation of YAP and modulation of the actin cytoskeleton are major components of the pro-proliferative action of miR-199a-3p and other miRNAs that induce cardiomyocyte proliferation."}],"oa_version":"Published Version","pmid":1,"author":[{"first_name":"Consuelo","last_name":"Torrini","full_name":"Torrini, Consuelo"},{"id":"850B2E12-9CD4-11E9-837F-E719E6697425","first_name":"Ryan J","last_name":"Cubero","full_name":"Cubero, Ryan J","orcid":"0000-0003-0002-1867"},{"first_name":"Ellen","last_name":"Dirkx","full_name":"Dirkx, Ellen"},{"first_name":"Luca","full_name":"Braga, Luca","last_name":"Braga"},{"last_name":"Ali","full_name":"Ali, Hashim","first_name":"Hashim"},{"last_name":"Prosdocimo","full_name":"Prosdocimo, Giulia","first_name":"Giulia"},{"last_name":"Gutierrez","full_name":"Gutierrez, Maria Ines","first_name":"Maria Ines"},{"full_name":"Collesi, Chiara","last_name":"Collesi","first_name":"Chiara"},{"full_name":"Licastro, Danilo","last_name":"Licastro","first_name":"Danilo"},{"full_name":"Zentilin, Lorena","last_name":"Zentilin","first_name":"Lorena"},{"full_name":"Mano, Miguel","last_name":"Mano","first_name":"Miguel"},{"full_name":"Zacchigna, Serena","last_name":"Zacchigna","first_name":"Serena"},{"first_name":"Michele","full_name":"Vendruscolo, Michele","last_name":"Vendruscolo"},{"full_name":"Marsili, Matteo","last_name":"Marsili","first_name":"Matteo"},{"first_name":"Areejit","full_name":"Samal, Areejit","last_name":"Samal"},{"last_name":"Giacca","full_name":"Giacca, Mauro","first_name":"Mauro"}],"external_id":{"pmid":["31141697"]},"article_processing_charge":"Yes","title":"Common regulatory pathways mediate activity of microRNAs inducing cardiomyocyte proliferation","citation":{"chicago":"Torrini, Consuelo, Ryan J Cubero, Ellen Dirkx, Luca Braga, Hashim Ali, Giulia Prosdocimo, Maria Ines Gutierrez, et al. “Common Regulatory Pathways Mediate Activity of MicroRNAs Inducing Cardiomyocyte Proliferation.” Cell Reports.

In order to reach this conclusion, we first identify the frequency with which different outcomes occur in a sample, as the variable carrying useful information on the generative process. The entropy of the frequency, that we call relevance, provides an upper bound to the number of informative bits. This differs from the entropy of the data, that we take as a measure of resolution. Samples that maximise relevance at a given resolution—that we call maximally informative samples—exhibit statistical criticality. In particular, Zipf's law arises at the optimal trade-off between resolution (i.e. compression) and relevance. As a byproduct, we derive a bound of the maximal number of parameters that can be estimated from a dataset, in the absence of prior knowledge on the generative model.\r\n\r\nFurthermore, we relate criticality to the statistical properties of the representation of the data generating process. We show that, as a consequence of the concentration property of the asymptotic equipartition property, representations that are maximally informative about the data generating process are characterised by an exponential distribution of energy levels. This arises from a principle of minimal entropy, that is conjugate of the maximum entropy principle in statistical mechanics. This explains why statistical criticality requires no parameter fine tuning in maximally informative samples."}],"extern":"1","date_updated":"2021-01-12T08:11:57Z","keyword":["optimization under uncertainty","source coding","large deviation"],"status":"public","type":"journal_article","article_type":"original","_id":"7130"},{"status":"public","type":"journal_article","article_type":"original","_id":"7150","extern":"1","date_updated":"2021-01-12T08:12:05Z","intvolume":" 32","month":"12","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1503.04963"}],"oa_version":"Preprint","abstract":[{"text":"In this work, we use algebraic methods for studying distance computation and subgraph detection tasks in the congested clique model.

Severe parasitic reactions cause poor rechargeability, efficiency, and cycle life and have been shown to be caused by singlet oxygen (1O2) that forms at all stages of cycling. However, its formation mechanism remains unclear. We show that disproportionation of superoxide, the product or intermediate on discharge and charge, to peroxide and oxygen is responsible for 1O2 formation. While the overall reaction is driven by the stability of peroxide and thus favored by stronger Lewis acidic cations such as Li+, the 1O2 fraction is enhanced by weak Lewis acids such as organic cations. Concurrently, the metal peroxide yield drops with increasing 1O2. The results explain a major parasitic pathway during cell cycling and the growing severity in K–, Na–, and Li–O2 cells based on the growing propensity for disproportionation. High capacities and rates with peroxides are now realized to require solution processes, which form peroxide or release O2via disproportionation. The results therefore establish the central dilemma that disproportionation is required for high capacity but also responsible for irreversible reactions. Highly reversible cell operation requires hence finding reaction routes that avoid disproportionation.","lang":"eng"}],"oa_version":"Published Version","month":"08","intvolume":" 12","citation":{"chicago":"Mourad, Eléonore, Yann K.

The significant problem of oxidizing the solid insulating lithium peroxide can greatly be facilitated by incorporating redox mediators that shuttle electron-holes between the porous substrate and lithium peroxide. Redox mediator stability is thus key for energy efficiency, reversibility, and cycle life. However, the gradual deactivation of redox mediators during repeated cycling has not conclusively been explained. Here, we show that organic redox mediators are predominantly decomposed by singlet oxygen that forms during cycling. Their reaction with superoxide, previously assumed to mainly trigger their degradation, peroxide, and dioxygen, is orders of magnitude slower in comparison. The reduced form of the mediator is markedly more reactive towards singlet oxygen than the oxidized form, from which we derive reaction mechanisms supported by density functional theory calculations. Redox mediators must thus be designed for stability against singlet oxygen."}],"month":"03","intvolume":" 10","extern":"1","ddc":["540"],"date_updated":"2021-01-12T08:12:44Z","file_date_updated":"2020-07-14T12:47:55Z","_id":"7280","status":"public","type":"journal_article","article_type":"original","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)"}},{"has_accepted_license":"1","year":"2019","day":"13","publication":"Angewandte Chemie International Edition","page":"6535-6539","doi":"10.1002/anie.201901869","date_published":"2019-05-13T00:00:00Z","date_created":"2020-01-15T07:19:27Z","quality_controlled":"1","publisher":"Wiley","oa":1,"citation":{"ama":"Petit YK, Leypold C, Mahne N, et al.

These reactions were recently revealed to be predominantly caused by singlet oxygen, which can be neutralized by chemical traps or physical quenchers. However, traps are irreversibly consumed and thus only active for a limited time, and so far identified quenchers lack oxidative stability to be suitable for typically required recharge potentials. Thus, reducing the charge potential within the stability limit of the quencher and/or finding more stable quenchers is required. Here, we show that dimethylphenazine as a redox mediator decreases the charge potential well within the stability limit of the quencher 1,4-diazabicyclo[2.2.2]octane. The quencher can thus mitigate the parasitic reactions without being oxidatively decomposed. At the same time the quencher protects the redox mediator from singlet oxygen attack.
