This includes the decidability of language inclusion, which is the ultimate verification problem. Operator precedence grammars, automata, and logics have been investigated and used, for example, to verify programs with arithmetic expressions and exceptions (both of which are deterministic pushdown but lie outside the scope of the visibly pushdown languages). In this paper, we complete the picture and give, for the first time, an algebraic characterization of the class of OPLs in the form of a syntactic congruence that has finitely many equivalence classes exactly for the operator precedence languages. This is a generalization of the celebrated Myhill-Nerode theorem for the regular languages to OPLs. As one of the consequences, we show that universality and language inclusion for nondeterministic operator precedence automata can be solved by an antichain algorithm. Antichain algorithms avoid determinization and complementation through an explicit subset construction, by leveraging a quasi-order on words, which allows the pruning of the search space for counterexample words without sacrificing completeness. Antichain algorithms can be implemented symbolically, and these implementations are today the best-performing algorithms in practice for the inclusion of finite automata. We give a generic construction of the quasi-order needed for antichain algorithms from a finite syntactic congruence. This yields the first antichain algorithm for OPLs, an algorithm that solves the ExpTime-hard language inclusion problem for OPLs in exponential time.","lang":"eng"}],"type":"conference","department":[{"_id":"GradSch"},{"_id":"ToHe"}],"volume":261,"corr_author":"1","publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","date_created":"2023-07-24T15:11:41Z","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"publication_status":"published","alternative_title":["LIPIcs"],"external_id":{"arxiv":["2305.03447"]},"conference":{"end_date":"2023-07-14","name":"ICALP: Automata, Languages and Programming","location":"Paderborn, Germany","start_date":"2023-07-10"},"_id":"13292","scopus_import":"1","month":"07"},{"publisher":"Springer Nature","corr_author":"1","volume":13965,"department":[{"_id":"GradSch"},{"_id":"ToHe"}],"citation":{"short":"T.A.

We present runtime verification of algorithmic fairness for systems whose models are unknown, but are assumed to have a Markov chain structure. We introduce a specification language that can model many common algorithmic fairness properties, such as demographic parity, equal opportunity, and social burden. We build monitors that observe a long sequence of events as generated by a given system, and output, after each observation, a quantitative estimate of how fair or biased the system was on that run until that point in time. The estimate is proven to be correct modulo a variable error bound and a given confidence level, where the error bound gets tighter as the observed sequence gets longer. Our monitors are of two types, and use, respectively, frequentist and Bayesian statistical inference techniques. While the frequentist monitors compute estimates that are objectively correct with respect to the ground truth, the Bayesian monitors compute estimates that are correct subject to a given prior belief about the system’s model. Using a prototype implementation, we show how we can monitor if a bank is fair in giving loans to applicants from different social backgrounds, and if a college is fair in admitting students while maintaining a reasonable financial burden on the society. Although they exhibit different theoretical complexities in certain cases, in our experiments, both frequentist and Bayesian monitors took less than a millisecond to update their verdicts after each observation."}],"quality_controlled":"1","month":"07","scopus_import":"1","_id":"13310","conference":{"start_date":"2023-07-17","location":"Paris, France","name":"CAV: Computer Aided Verification","end_date":"2023-07-22"},"external_id":{"arxiv":["2305.15979"],"isi":["001310804800017"]},"alternative_title":["LNCS"],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"publication_status":"published","date_created":"2023-07-25T18:32:40Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","project":[{"call_identifier":"H2020","name":"Vigilant Algorithmic Monitoring of Software","_id":"62781420-2b32-11ec-9570-8d9b63373d4d","grant_number":"101020093"}],"ddc":["000"],"isi":1,"arxiv":1,"publication":"Computer Aided Verification","acknowledgement":"This work is supported by the European Research Council under Grant No.: ERC-2020-AdG101020093.","publication_identifier":{"eissn":["1611-3349"],"eisbn":["9783031377037"],"isbn":["9783031377020"],"issn":["0302-9743"]},"year":"2023","ec_funded":1,"oa":1,"file":[{"content_type":"application/pdf","checksum":"ccaf94bf7d658ba012c016e11869b54c","relation":"main_file","date_updated":"2023-07-31T08:11:20Z","file_id":"13327","access_level":"open_access","file_name":"2023_LNCS_CAV_HenzingerT.pdf","date_created":"2023-07-31T08:11:20Z","success":1,"creator":"dernst","file_size":647760}],"day":"18","doi":"10.1007/978-3-031-37703-7_17","date_published":"2023-07-18T00:00:00Z","intvolume":"     13965","status":"public","language":[{"iso":"eng"}],"article_processing_charge":"Yes (in subscription journal)","has_accepted_license":"1","file_date_updated":"2023-07-31T08:11:20Z","author":[{"first_name":"Thomas A","orcid":"0000-0002-2985-7724","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","last_name":"Henzinger","full_name":"Henzinger, Thomas A"},{"orcid":"0009-0005-0820-1696","full_name":"Karimi, Mahyar","last_name":"Karimi","id":"6e5417ba-5355-11ee-ae5a-94c2e510b26b","first_name":"Mahyar"},{"orcid":"0000-0001-8974-2542","id":"8121a2d0-dc85-11ea-9058-af578f3b4515","full_name":"Kueffner, Konstantin","last_name":"Kueffner","first_name":"Konstantin"},{"orcid":"0000-0001-9864-7475","last_name":"Mallik","full_name":"Mallik, Kaushik","id":"0834ff3c-6d72-11ec-94e0-b5b0a4fb8598","first_name":"Kaushik"}],"title":"Monitoring algorithmic fairness","date_updated":"2026-01-21T07:24:31Z","page":"358–382","oa_version":"Published Version"},{"date_created":"2023-07-30T22:01:02Z","publication_status":"published","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"external_id":{"pmid":["37463204"],"isi":["001121663500001"]},"_id":"13315","scopus_import":"1","issue":"30","month":"07","quality_controlled":"1","type":"journal_article","pmid":1,"abstract":[{"text":"How do statistical dependencies in measurement noise influence high-dimensional inference? To answer this, we study the paradigmatic spiked matrix model of principal components analysis (PCA), where a rank-one matrix is corrupted by additive noise. We go beyond the usual independence assumption on the noise entries, by drawing the noise from a low-order polynomial orthogonal matrix ensemble. The resulting noise correlations make the setting relevant for applications but analytically challenging. We provide characterization of the Bayes optimal limits of inference in this model. If the spike is rotation invariant, we show that standard spectral PCA is optimal. However, for more general priors, both PCA and the existing approximate message-passing algorithm (AMP) fall short of achieving the information-theoretic limits, which we compute using the replica method from statistical physics. We thus propose an AMP, inspired by the theory of adaptive Thouless–Anderson–Palmer equations, which is empirically observed to saturate the conjectured theoretical limit. This AMP comes with a rigorous state evolution analysis tracking its performance. Although we focus on specific noise distributions, our methodology can be generalized to a wide class of trace matrix ensembles at the cost of more involved expressions. Finally, despite the seemingly strong assumption of rotation-invariant noise, our theory empirically predicts algorithmic performance on real data, pointing at strong universality properties.","lang":"eng"}],"citation":{"mla":"Barbier, Jean, et al. “Fundamental Limits in Structured Principal Component Analysis and How to Reach Them.” <i>Proceedings of the National Academy of Sciences of the United States of America</i>, vol. 120, no. 30, e2302028120, National Academy of Sciences, 2023, doi:<a href=\"https://doi.org/10.1073/pnas.2302028120\">10.1073/pnas.2302028120</a>.","ista":"Barbier J, Camilli F, Mondelli M, Sáenz M. 2023.

The structure and properties of the endocytic early/sorting compartment differ significantly between organisms; in plant cells, the trans-Golgi network (TGN) serves this role, whereas in mammalian cells a separate intracellular structure performs this function. The yeast syntaxin homolog Tlg2p, widely localizing to the TGN and endosomal compartments, is presumed to act as a Q-SNARE for endocytic vesicles, but which compartment is the direct target for endocytic vesicles remained unanswered. Here we demonstrate by high-speed and high-resolution 4D imaging of fluorescently labeled endocytic cargos that the Tlg2p-residing compartment within the TGN functions as the early/sorting compartment. After arriving here, endocytic cargos are recycled to the plasma membrane or transported to the yeast Rab5-residing endosomal compartment through the pathway requiring the clathrin adaptors GGAs. Interestingly, Gga2p predominantly localizes at the Tlg2p-residing compartment, and the deletion of GGAs has little effect on another TGN region where Sec7p is present but suppresses dynamics of the Tlg2-residing early/sorting compartment, indicating that the Tlg2p- and Sec7p-residing regions are discrete entities in the mutant. Thus, the Tlg2p-residing region seems to serve as an early/sorting compartment and function independently of the Sec7p-residing region within the TGN.","lang":"eng"}],"publisher":"eLife Sciences Publications","department":[{"_id":"DaSi"}],"volume":12},{"month":"10","scopus_import":"1","_id":"13319","external_id":{"pmid":["37766789"],"arxiv":["2303.15949"],"isi":["001033655400002"]},"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"publication_status":"published","date_created":"2023-07-30T22:01:03Z","publisher":"Springer Nature","corr_author":"1","volume":403,"department":[{"_id":"JaMa"}],"citation":{"ama":"Vernooij M, Wirth M.

The multi-layer structure models inference from deep generative priors, and the rotational invariance imposed on the weights generalizes the i.i.d. Gaussian assumption by allowing for a complex correlation structure, which is typical in applications. In this work, we present a new class of approximate message passing (AMP) algorithms and give a state evolution recursion which precisely characterizes their performance in the large system limit. In contrast with the existing multi-layer VAMP (ML-VAMP) approach, our proposed AMP – dubbed multilayer rotationally invariant generalized AMP (ML-RI-GAMP) – provides a natural generalization beyond Gaussian designs, in the sense that it recovers the existing Gaussian AMP as a special case. Furthermore, ML-RI-GAMP exhibits a significantly lower complexity than ML-VAMP, as the computationally intensive singular value decomposition is replaced by an estimation of the moments of the design matrices. Finally, our numerical results show that this complexity gain comes at little to no cost in the performance of the algorithm."}],"quality_controlled":"1","month":"05","scopus_import":"1","_id":"13321","conference":{"end_date":"2023-04-28","name":"ITW: Information Theory Workshop","location":"Saint-Malo, France","start_date":"2023-04-23"},"external_id":{"arxiv":["2212.01572"],"isi":["001031733100053"]},"publication_status":"published","date_created":"2023-07-30T22:01:04Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","project":[{"_id":"059876FA-7A3F-11EA-A408-12923DDC885E","name":"Prix Lopez-Loretta 2019 - Marco Mondelli"}],"isi":1,"publication":"2023 IEEE Information Theory Workshop","arxiv":1,"year":"2023","acknowledgement":"Marco Mondelli was partially supported by the 2019 Lopez-Loreta prize.","publication_identifier":{"isbn":["9798350301496"],"eissn":["2475-4218"]},"oa":1,"day":"01","doi":"10.1109/ITW55543.2023.10160238","date_published":"2023-05-01T00:00:00Z","status":"public","language":[{"iso":"eng"}],"article_processing_charge":"No","title":"Approximate message passing for multi-layer estimation in rotationally invariant models","author":[{"first_name":"Yizhou","full_name":"Xu, Yizhou","last_name":"Xu"},{"first_name":"Tian Qi","last_name":"Hou","full_name":"Hou, Tian Qi"},{"full_name":"Liang, Shan Suo","last_name":"Liang","first_name":"Shan Suo"},{"first_name":"Marco","id":"27EB676C-8706-11E9-9510-7717E6697425","last_name":"Mondelli","full_name":"Mondelli, Marco","orcid":"0000-0002-3242-7020"}],"date_updated":"2025-04-15T07:50:16Z","page":"294-298","oa_version":"Preprint"},{"year":"2023","oa":1,"citation":{"apa":"Kleshnina, M.

However, this reaction typically requires ultraviolet light, which limits applicability. In this study, we introduce disequilibration by sensitization under confinement (DESC), a supramolecular approach to induce the E-to-Z isomerization by using light of a desired color, including red. DESC relies on a combination of a macrocyclic host and a photosensitizer, which act together to selectively bind and sensitize E-azobenzenes for isomerization. The Z isomer lacks strong affinity for and is expelled from the host, which can then convert additional E-azobenzenes to the Z state. In this way, the host–photosensitizer complex converts photon energy into chemical energy in the form of out-of-equilibrium photostationary states, including ones that cannot be accessed through direct photoexcitation."}],"pmid":1,"citation":{"mla":"Gemen, Julius, et al. “Disequilibrating Azoarenes by Visible-Light Sensitization under Confinement.” <i>Science</i>, vol. 381, no. 6664, American Association for the Advancement of Science, 2023, pp. 1357–63, doi:<a href=\"https://doi.org/10.1126/science.adh9059\">10.1126/science.adh9059</a>.","ista":"Gemen J, Church JR, Ruoko T-P, Durandin N, Białek MJ, Weissenfels M, Feller M, Kazes M, Borin VA, Odaybat M, Kalepu R, Diskin-Posner Y, Oron D, Fuchter MJ, Priimagi A, Schapiro I, Klajn R. 2023.

Individual compositional parameters like chemotactic signals, adhesiveness, and pore sizes are well known to be sensed by motile cells, providing individual guidance cues for cellular pathfinding. However, motile cells encounter diverse mechanochemical signals at the same time, raising the question of how cells respond to locally diverse and potentially competing signals on their migration routes. Here, we reveal that motile amoeboid cells require nuclear repositioning, termed nucleokinesis, for adaptive pathfinding in heterogeneous mechanochemical microenvironments. Using mammalian immune cells and the amoeba<jats:italic>Dictyostelium discoideum</jats:italic>, we discover that frequent, rapid and long-distance nucleokinesis is a basic component of amoeboid pathfinding, enabling cells to reorientate quickly between locally competing cues. Amoeboid nucleokinesis comprises a two-step cell polarity switch and is driven by myosin II-forces, sliding the nucleus from a ‘losing’ to the ‘winning’ leading edge to re-adjust the nuclear to the cellular path. Impaired nucleokinesis distorts fast path adaptions and causes cellular arrest in the microenvironment. Our findings establish that nucleokinesis is required for amoeboid cell navigation. Given that motile single-cell amoebae, many immune cells, and some cancer cells utilize an amoeboid migration strategy, these results suggest that amoeboid nucleokinesis underlies cellular navigation during unicellular biology, immunity, and disease.","lang":"eng"}],"citation":{"apa":"Kroll, J., Hauschild, R., Kuznetcov, A., Stefanowski, K., Hermann, M.

However, to what extent the properties of such supramolecular crystals actually resemble those of atomic materials often remains unclear. Here, we present coarse-grained molecular simulations explicitly demonstrating how a behavior evocative of that of semiconductors may emerge in a colloidal superlattice. As a case study, we focus on gold nanoparticles bearing positively charged groups that self-assemble into FCC crystals via mediation by citrate counterions. In silico ohmic experiments show how the dynamically diverse behavior of the ions in different superlattice domains allows the opening of conductive ionic gates above certain levels of applied electric fields. The observed binary conductive/nonconductive behavior is reminiscent of that of conventional semiconductors, while, at a supramolecular level, crossing the “band gap” requires a sufficient electrostatic stimulus to break the intermolecular interactions and make ions diffuse throughout the superlattice’s cavities.","lang":"eng"}],"type":"journal_article","extern":"1","citation":{"apa":"Lionello, C., Perego, C., Gardin, A., Klajn, R., &#38; Pavan, G.

Exposure to light converts PAGs into dianionic products incapable of maintaining the NPs in an assembled state, resulting in light-triggered disassembly of NP aggregates. To demonstrate the proof-of-concept, we work with an organic PAG incorporating the UV-cleavable o-nitrobenzyl moiety and an inorganic PAG, the photosensitive trioxalatocobaltate(III) complex, which absorbs light across the entire visible spectrum. Both PAGs were used to prepare either amorphous NP assemblies or regular superlattices with a long-range NP order. These NP aggregates disassembled rapidly upon light exposure for a specific time, which could be tuned by the incident light wavelength or the amount of PAG used. Selective excitation of the inorganic PAG in a system combining the two PAGs results in a photodecomposition product that deactivates the organic PAG, enabling nontrivial disassembly profiles under a single type of external stimulus."}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1021/jacs.2c11973"}],"publisher":"American Chemical Society","volume":145,"external_id":{"pmid":["36757850"]},"date_created":"2023-08-01T09:33:08Z","publication_status":"published","scopus_import":"1","issue":"7","month":"02","_id":"13354"},{"quality_controlled":"1","citation":{"ista":"Sunko V, Sun Y, Vranas M, Homes CC, Lee C, Donoway E, Wang Z-C, Balguri S, Mahendru MB, Ruiz A, Gunn B, Basak R, Blanco-Canosa S, Schierle E, Weschke E, Tafti F, Frano A, Orenstein J. 2023.

Surprisingly, this giant peak occurs at 18 K, well above the Néel temperature (𝑇𝑁) of 11.5 K. Using a suite of sensitive probes of magnetism, including resonant x-ray scattering and magneto-optical polarimetry, we have discovered that ferromagnetic order onsets above 𝑇𝑁 in the temperature range of the resistivity peak. The observation of inverted hysteresis in this regime shows that ferromagnetism is promoted by coupling of localized spins and itinerant carriers. The resulting carrier localization is confirmed by optical conductivity measurements.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2208.05499"}],"publisher":"American Physical Society","OA_type":"green","volume":107,"external_id":{"arxiv":["2208.05499"]},"date_created":"2025-06-10T09:08:40Z","publication_status":"published","issue":"14","scopus_import":"1","month":"04","_id":"19803","year":"2023","publication_identifier":{"issn":["2469-9950"],"eissn":["2469-9969"]},"article_type":"original","article_number":"144404","date_published":"2023-04-04T00:00:00Z","intvolume":"       107","oa":1,"doi":"10.1103/physrevb.107.144404","day":"04","OA_place":"repository","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","arxiv":1,"publication":"Physical Review B","oa_version":"Preprint","article_processing_charge":"No","status":"public","language":[{"iso":"eng"}],"date_updated":"2025-06-10T11:02:42Z","title":"Spin-carrier coupling induced ferromagnetism and giant resistivity peak in EuCd2P2","author":[{"orcid":"0000-0003-2724-3523","id":"23cb1cf6-2c7a-11ef-91a4-f72fc19f20b3","last_name":"Sunko","full_name":"Sunko, Veronika","first_name":"Veronika"},{"first_name":"Y.","full_name":"Sun, Y.","last_name":"Sun"},{"last_name":"Vranas","full_name":"Vranas, M.","first_name":"M."},{"full_name":"Homes, C.

Here, we demonstrate that the DC bias strain-dependence of AC elastocaloric effect allows decomposition of the latter into symmetric (rotation-symmetry-preserving) and antisymmetric (rotation-symmetry-breaking) strain channels, using a tetragonal \r\n-electron intermetallic DyB2C2—whose antiferroquadrupolar order breaks local fourfold rotational symmetries while globally remaining tetragonal—as a showcase example. We capture the strain evolution of its quadrupolar and magnetic phase transitions using both singularities in the elastocaloric coefficient and its jumps at the transitions, and the latter we show follows a modified Ehrenfest relation. We find that antisymmetric strain couples to the underlying order parameter in a biquadratic (linear-quadratic) manner in the antiferroquadrupolar (canted antiferromagnetic) phase, which are attributed to a preserved (broken) global tetragonal symmetry, respectively. The broken tetragonal symmetry in the magnetic phase is further evidenced by elastocaloric strain-hysteresis and optical birefringence. Additionally, within the staggered quadrupolar order, the observed elastocaloric response reflects a quadratic increase of entropy with antisymmetric strain, analogous to the role magnetic field plays for Ising antiferromagnetic orders by promoting pseudospin flips. Our results demonstrate AC elastocaloric effect as a compact and incisive thermodynamic probe into the coupling between electronic degrees of freedom and strain in free energy, which holds the potential for investigating and understanding the symmetry of a wide variety of ordered phases in broader classes of quantum materials."}],"type":"journal_article","pmid":1,"extern":"1","OA_type":"hybrid","volume":120,"main_file_link":[{"url":"https://doi.org/10.1073/pnas.2302800120","open_access":"1"}],"publisher":"National Academy of Sciences"},{"date_updated":"2025-06-11T06:14:06Z","related_material":{"link":[{"url":"https://doi.org/10.1063/5.0195810","relation":"erratum"}]},"author":[{"full_name":"Sun, F.","last_name":"Sun","first_name":"F."},{"full_name":"Mishra, S.","last_name":"Mishra","first_name":"S."},{"first_name":"P.

Two laser beams are used, one as a source to locally modulate the sample temperature, and the other as a probe of sample reflectivity, which is a function of the modulated temperature. Thermal diffusivity is obtained from the phase delay between source and probe signals. We combine this technique with a microscope setup in an optical cryostat, in which the sample is placed on a three-axis piezo-stage, allowing for spatially resolved measurements. Furthermore, we demonstrate experimentally and mathematically that isotropic in-plane diffusivity can be obtained when overlapping the two laser beams instead of separating them in the traditional way, which further enhances the spatial resolution to a micron scale, especially valuable when studying inhomogeneous or multidomain samples. We discuss in detail the experimental conditions under which this technique is valuable and demonstrate its performance on two stoichiometric bilayer ruthenates: Sr3Ru2O7 and Ca3Ru2O7. The spatial resolution allowed us to study the diffusivity in single domains of the latter, and we uncovered a temperature-dependent in-plane diffusivity anisotropy. Finally, we used the enhanced spatial resolution enabled by overlapping the two beams to measure the temperature-dependent diffusivity of Ti-doped Ca3Ru2O7, which exhibits a metal–insulator transition. We observed large variations of transition temperature over the same sample, originating from doping inhomogeneity and pointing to the power of spatially resolved techniques in accessing inherent properties.","lang":"eng"}],"pmid":1,"type":"journal_article","extern":"1","citation":{"short":"F.

The capacity of a link (u, v) is determined by how much nodes u and v allocate for this link. Specifically, the input is a finite ordered sequence of packets that arrive in both directions along a link. Given (u, v) and a packet of weight x going from u to v, node u can either accept or reject the packet. If u accepts the packet, the capacity on link (u, v) decreases by x. Correspondingly, v’s capacity on (u, v) increases by x. If a node rejects the packet, this will entail a cost affinely linear in the weight of the packet. A link is “rechargeable” in the sense that the total capacity of the link has to remain constant, but the allocation of capacity at the ends of the link can depend arbitrarily on the nodes’ decisions. The goal is to minimise the sum of the capacity injected into the link and the cost of rejecting packets. We show that the problem is NP-hard, but can be approximated efficiently with a ratio of (1 + E) . (1 + square3) for some arbitrary E>0."}],"_id":"19985","scopus_import":"1","month":"05","date_created":"2025-07-10T13:15:43Z","publication_status":"published","alternative_title":["LNCS"],"external_id":{"isi":["001292782600026"]},"conference":{"start_date":"2023-06-06","location":"Alcalá de Henares, Spain","name":"SIROCCO: International Colloquium on Structural Information and Communication Complexity","end_date":"2023-06-09"}},{"title":"Multivariate Dirichlet moments and a polychromatic Ewens sampling formula","author":[{"full_name":"Dello Schiavo, Lorenzo","last_name":"Dello Schiavo","id":"ECEBF480-9E4F-11EA-B557-B0823DDC885E","orcid":"0000-0002-9881-6870","first_name":"Lorenzo"},{"orcid":"0009-0000-9773-1931","id":"3ebd6ba8-edfb-11eb-afb5-91a9745ba308","full_name":"Quattrocchi, Filippo","last_name":"Quattrocchi","first_name":"Filippo"}],"date_updated":"2025-11-24T13:53:48Z","language":[{"iso":"eng"}],"status":"public","article_processing_charge":"No","oa_version":"Preprint","keyword":["Dirichlet distribution","Ewens sampling formula","Hoppe urn model","colored partitions"],"publication":"arXiv","arxiv":1,"project":[{"grant_number":"E208","_id":"34dbf174-11ca-11ed-8bc3-afe9d43d4b9c","name":"Configuration Spaces over Non-Smooth Spaces"},{"call_identifier":"FWF","grant_number":"F06504","name":"Taming Complexity in Partial Differential Systems","_id":"260482E2-B435-11E9-9278-68D0E5697425"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","OA_place":"repository","oa":1,"day":"20","doi":"10.48550/arXiv.2309.11292","date_published":"2023-09-20T00:00:00Z","article_number":"2309.11292","acknowledgement":"This research was funded by the Austrian Science Fund (FWF) ESPRIT 208.
