Of the many ways in which they influence natural phenomena, perhaps the most consequential is their capacity to transfer electrical charge during contact4,5,6,7,8,9,10—which occurs even between samples of the same oxide—yet the symmetry-breaking parameter that causes this remains unidentified11,12. Here we show that adventitious carbonaceous molecules adsorbed from the environment are the symmetry-breaking factor in same-material oxide contact electrification (CE). We use acoustic levitation to measure charge exchange between a sphere and a plate composed of identical amorphous silicon dioxide (SiO2). Although charging polarity is random for co-prepared samples, we control it with baking or plasma treatment. Observing the charge-exchange relaxation afterwards, we see dynamics over a timescale of hours and connect this directly to the presence of adventitious carbon with time-of-flight mass spectrometry, low-energy ion scattering and infrared spectroscopy. Going further, we confirm that adventitious carbon can even determine charge exchange among different oxides. Our results identify the symmetry-breaking parameter that causes insulating oxides to exchange charge in settings ranging from desert sands4 to volcanic plumes5,6, while simultaneously highlighting an overlooked factor in CE more broadly."}],"quality_controlled":"1","volume":651,"language":[{"iso":"eng"}],"corr_author":"1","department":[{"_id":"ScWa"},{"_id":"GradSch"},{"_id":"LifeSc"}],"external_id":{"pmid":["41851325"]},"date_created":"2026-03-23T15:04:00Z","publication_status":"published","oa":1,"publication_identifier":{"eissn":["1476-4687"],"issn":["0028-0836"]},"acknowledgement":"This project has received support from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreement no. 949120) and from the Marie Skłodowska-Curie programme (grant agreement no. 754411).

Here we show that in zebrafish, the geometry of the fertilized egg—specifically its curvature and volume—serves as a critical initial condition triggering a cascade of events that influence development. The embryo geometry guides patterned asymmetric cell divisions in the blastoderm, generating radial gradients of cell volume and nucleocytoplasmic ratio. These gradients generate mitotic phase waves, with the nucleocytoplasmic ratio determining individual cell cycle periods independently of other cells. We demonstrate that reducing cell autonomy reshapes these waves, emphasizing the instructive role of geometry-derived volume patterns in setting the intrinsic period of the cell cycle oscillator. In addition to organizing cell cycles, early embryo geometry spatially patterns zygotic genome activation at the midblastula transition, a key step in establishing embryonic autonomy. Disrupting the embryo shape alters the zygotic genome activation pattern and causes ectopic germ layer specification, underscoring the developmental significance of geometry. Together, our findings reveal a symmetry-breaking function of early embryo geometry in coordinating cell cycle and transcriptional patterning."}]},{"DOAJ_listed":"1","acknowledgement":"We thank Andrea Navas-Olive and Rebecca J.

However, CA3 also forms an autoassociative network, and its PNs have diverse morphologies, intrinsic properties, and GC input levels. How PN subtypes compose this recurrent network is unknown. To determine the synaptic arrangement of identified CA3 PNs, we combine multicellular patch-clamp recording and post hoc morphological analysis in mouse hippocampal slices. PNs can be divided into distinct “superficial” and “deep” subclasses, the latter including previously reported “athorny” cells. Subclasses have distinct input-output transformations and asymmetric connectivity, which is more abundant from superficial to deep PNs, splitting CA3 locally into two parallel recurrent networks. Coincident spontaneous inhibition occurs frequently within but not between subclasses, implying subclass-specific inhibitory innervation.

Injection locking of the oscillations results in well-developed current plateaux.

Nevertheless, they have yet to attain widespread use in plants, largely due to plants’ challenging optical properties. Expansion microscopy improves effective resolution by isotropically increasing the physical distances between sample structures while preserving relative spatial arrangements and clearing the sample. However, its application to plants has been hindered by the rigid, mechanically cohesive structure of plant tissues. Here, we report on whole-mount expansion microscopy of thale cress (Arabidopsis thaliana) root tissues (PlantEx), achieving a four-fold resolution increase over conventional microscopy. Our results highlight the microtubule cytoskeleton organization and interaction between molecularly defined cellular constituents. Combining PlantEx with stimulated emission depletion (STED) microscopy, we increase nanoscale resolution and visualize the complex organization of subcellular organelles from intact tissues by example of the densely packed COPI-coated vesicles associated with the Golgi apparatus and put these into a cellular structural context. Our results show that expansion microscopy can be applied to increase effective imaging resolution in Arabidopsis root specimens.

Two varieties of wild snapdragon (Antirrhinum majus) characterized by divergent flower color hybridize in their native range. Selection on flower color genes is indicated by sharp clines, but the selective agents have not been demonstrated. Although previous work has focused on pollinators, pigmentation genes can also contribute to abiotic stress tolerance. We hypothesized that pigmentation in A. majus mediates stress tolerance, which could contribute to hybrid zone maintenance through parental niche divergence or hybrid maladaptation. Specifically, we tested whether morphotype mediates drought tolerance in an experiment comparing magenta-flowered var. pseudomajus, yellow-flowered var. striatum, and their pink-flowered hybrid cross.\r\nMethods: We experimentally compared drought tolerance of each morphotype from allopatric crosses within and between varieties using three greenhouse treatments. Control plants were watered as needed, while drought-treated plants were watered half as often, either from the transplant stage (“early” drought), or from flowering onset (“late” drought).\r\nResults: Parental morphotypes responded identically to drought in fitness and most phenotypic traits. However, hybrids had lower survival (14%) under late drought stress than parental morphotypes (70%). All hybrids that flowered in the late drought treatment died, compared to ~20% of flowering parental morphotypes.\r\nConclusions: Hybrid maladaptation to abiotic stress could potentially contribute to flower color divergence in the face of gene flow in A. majus. Further research should test the relevance of our results to field conditions and explicitly probe the role of flower color genes in drought tolerance.","lang":"eng"}],"article_number":"e70129"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_published":"2025-12-11T00:00:00Z","has_accepted_license":"1","project":[{"grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships"},{"_id":"23870BE8-32DE-11EA-91FC-C7463DDC885E","grant_number":"209504/A/17/Z","name":"Molecular mechanisms of neural circuit function"}],"year":"2025","oa_version":"Published Version","date_updated":"2026-01-05T11:00:03Z","type":"journal_article","day":"11","publisher":"Springer Nature","status":"public","tmp":{"short":"CC BY (4.0)","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)"},"doi":"10.1038/s41467-025-66409-0","OA_place":"publisher","article_type":"original","OA_type":"gold","ddc":["570"],"article_processing_charge":"Yes","citation":{"chicago":"Artan, Murat, Hanna Schön, and Mario de Bono. “Proximity Labeling of DAF-16 FOXO Highlights Aging Regulatory Proteins.” <i>Nature Communications</i>.

Here, we use proximity labeling to identify proteins interacting with the C. elegans FOXO DAF-16. We show that in well-fed, unstressed animals harboring active insulin signaling, DAF-16 forms a complex with the PAR-1/MARK serine/threonine kinase, a key regulator of cell polarity. PAR-1 inhibits DAF-16 accumulation and promotes DAF-16 phosphorylation at S249, at a conserved motif that PAR-1/human MARK2 phosphorylates in vitro. DAF-2 insulin-like receptor signaling stimulates DAF-16 S249 phosphorylation, suggesting DAF-2 activates PAR-1. DAF-2 also promotes PAR-1 expression by inhibiting DAF-16. PAR-1 knockdown, or DAF-16 S249A, prolong lifespan, whereas phosphomimetic DAF-16 S249D suppresses the longevity of daf-2 mutants. At low insulin signaling, DAF-16 proximity labeling highlights transcription factors, chromatin regulators, and DNA repair proteins. One interactor, the zinc finger/homeobox protein ZFH-2/ZFHX3, forms a complex with DAF-16 and prolongs lifespan.

Since its introduction, the medial axis has been used extensively in many applications as a method of computing a skeleton topologically equivalent to the original set. Unfortunately, one limiting factor in the use of the medial axis of a smooth manifold is that it is not necessarily topologically stable under small perturbations of the manifold. To counter these instabilities, various prunings of the medial axis have been proposed in the computational geometry community. Here, we examine one type of pruning, called burning. Because of the good experimental results it was hoped that the burning method of simplifying the medial axis would be stable. In this work, we show a simple example that dashes such hopes. Based on Bing’s house with two rooms, we demonstrate an isotopy of a shape where the medial axis goes from collapsible to non-collapsible. More precisely, we consider the standard deformation retract from the closed ball to Bing’s house with two rooms, but stop just short of the point where Bing’s house becomes two dimensional. This way we obtain an isotopy from the 3-ball to a thickened version of Bing’s house. Under this isotopy, the medial axis goes from collapsible to non-collapsible. We stress that this isotopy can be made generic, in the sense of singularity theory, as developed by Arnol’d and Thom."}],"publication_status":"published","corr_author":"1","language":[{"iso":"eng"}],"department":[{"_id":"HeEd"}],"date_created":"2025-08-31T22:01:33Z"},{"file":[{"content_type":"application/x-xz","checksum":"794c02f8c82ca59ba6dda3bd7eed871a","date_updated":"2025-06-25T13:38:07Z","date_created":"2025-06-25T13:38:07Z","file_id":"19905","file_name":"Thesis Valentin Hübner source.tar.xz","creator":"vhuebner","file_size":6192760,"relation":"source_file","access_level":"closed"},{"access_level":"open_access","relation":"main_file","file_size":4837864,"creator":"vhuebner","file_name":"Thesis Valentin Hübner.pdf","date_created":"2025-07-09T13:37:00Z","file_id":"19976","date_updated":"2025-07-09T13:37:00Z","content_type":"application/pdf","checksum":"ac56063d81c81e40322b6ff5a8c4912e"}],"acknowledgement":"The research for this thesis was supported by the European Research Council\r\n(grant agreements No. 863818 and No. 850529), the European Union’s Horizon 2020 research and innovation programme (Marie Skłodowska-Curie grant agreement No. 754411),\r\nthe Austrian Science Fund (grant DOI 10.55776/COE12), the French Agence Nationale\r\nde la Recherche under the Programme d’investissements d’avenir (project reference 17-\r\nEURE-0010) and the Australian Government through the Australian Research Council\r\n(grant No. SR200100005, “Securing Antarctica’s Environmental Future”).","publication_identifier":{"issn":["2663-337X"]},"oa":1,"file_date_updated":"2025-07-09T13:37:00Z","author":[{"orcid":"0009-0001-5009-4987","id":"2c8aa207-dc7d-11ea-9b2f-f22972ecd910","first_name":"Valentin","last_name":"Hübner","full_name":"Hübner, Valentin"}],"ec_funded":1,"supervisor":[{"orcid":"0000-0002-4561-241X","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","first_name":"Krishnendu","full_name":"Chatterjee, Krishnendu","last_name":"Chatterjee"}],"abstract":[{"lang":"eng","text":"Cooperation, that is, one person paying a cost for another's benefit, is a fundamental principle without which no form of society could exist. The extent to which humans cooperate with each other is also an essential feature that differentiates them from other animals. Cooperation occurs even in the absence of altruistic motivations, when it is selfishly incentivised by the expectation of a future reward. For example, many economic interactions are well described that way. This kind of cooperation requires that people exhibit reciprocal behaviour that acts as a mechanism that rewards cooperation.\r\nWith game-theoretic models, it is possible to formally study potential such mechanisms and under what conditions they can exist. This thesis contributes to this effort by analysing recently introduced models of cooperation that advance on previous work by taking into account the potential for pre-existing inequality among cooperating individuals as well as the different forms that reciprocity can take.\r\nIndividuals may differ both intrinsically, in their abilities, as well as extrinsically, in the amount of resources they have available. Allowing for such differences in a model of cooperation helps to understand how inequality affects the potential for, and outcomes of, cooperation among unequals. In this thesis, it is shown that in the presence of intrinsic inequality, a similar unequal distribution of resources can increase the potential for cooperation. This effect is stronger the smaller the group is in which cooperation takes place. It is also shown that under particular assumptions, if the unequal members of a group vary the size of their contributions to a cooperative effort over time, they can thereby increase their efficiency and improve the collective outcome.\r\nCooperative behaviour in a two-person interaction can be rewarded either by direct reciprocation whenever the same two people interact again, or indirectly by a third party who observed the interaction. In the latter case of indirect reciprocity, individuals are proximally rewarded by a good reputation, which ultimately translates to being rewarded with cooperative behaviour by others. This mechanism can enable selfishly motivated cooperation even in circumstances where individuals are unlikely to meet again, akin to how money facilitates trade. While these two forms of reciprocity have mostly been studied in isolation, this thesis analyses both direct and indirect reciprocity in a general model in order to compare their relative effectiveness under different circumstances. The contribution of this thesis is an extension of previous work regarding a specific kind of interaction, whose parameters allow for convenient mathematical analysis, to the most general set of possible interactions."}],"license":"https://creativecommons.org/licenses/by-nc/4.0/","degree_awarded":"PhD","publication_status":"published","date_created":"2025-06-25T13:50:10Z","department":[{"_id":"GradSch"},{"_id":"KrCh"}],"corr_author":"1","language":[{"iso":"eng"}],"status":"public","tmp":{"short":"CC BY-NC (4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc/4.0/legalcode","name":"Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)","image":"/images/cc_by_nc.png"},"day":"25","publisher":"Institute of Science and Technology Austria","type":"dissertation","project":[{"_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","grant_number":"863818","call_identifier":"H2020","name":"Formal Methods for Stochastic Models: Algorithms and Applications"},{"name":"ISTplus - Postdoctoral Fellowships","call_identifier":"H2020","grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425"}],"date_published":"2025-06-25T00:00:00Z","has_accepted_license":"1","date_updated":"2026-04-07T12:30:57Z","oa_version":"Published Version","year":"2025","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","page":"157","_id":"19903","month":"06","title":"Reciprocity and inequality in social dilemmas","article_processing_charge":"No","related_material":{"record":[{"id":"19843","status":"public","relation":"part_of_dissertation"},{"id":"15083","relation":"part_of_dissertation","status":"public"},{"id":"19074","status":"public","relation":"part_of_dissertation"}]},"citation":{"ieee":"V.

In this game, individuals can use their endowments to make contributions towards a good that benefits everyone. Each individual, however, is tempted to free-ride on the contributions of others. Herein, we study repeated public goods games among asymmetric players. Previous work has explored to which extent asymmetry allows for full cooperation, such that players contribute their full endowment each round. However, by design that work focusses on equilibria where individuals make the same contribution each round. Instead, here we consider players whose contributions along the equilibrium path can change from one round to the next. We do so for three different models – one without any budget constraints, one with endowment constraints, and one in which individuals can save their current endowment to be used in subsequent rounds. In each case, we explore two key quantities: the welfare and the resource efficiency that can be achieved in equilibrium. Welfare corresponds to the sum of all players’ payoffs. Resource efficiency relates this welfare to the total contributions made by the players. Compared to constant contribution sequences, we find that time-dependent contributions can improve resource efficiency across all three models. Moreover, they can improve the players’ welfare in the model with savings.","lang":"eng"}]},{"_id":"14451","month":"01","title":"Multi-objective reward generalization: Improving performance of Deep Reinforcement Learning for applications in single-asset trading","article_processing_charge":"Yes (via OA deal)","citation":{"apa":"Cornalba, F., Disselkamp, C., Scassola, D., &#38; Helf, C.

However, quantifying resource exploitation patterns through space and time can be difficult, complicating their incorporation in spatial ecology studies. Therefore, understanding the local drivers of spatial patterns of resource exploitation may contribute to better large-scale species distribution models.\r\nObjectives: We investigated (1) how the resource exploitation patterns of two trophic interactions (plant–insect) are explained by insect behaviour, resource aggregation, and potential insect-insect interactions. We also analyzed how (2) resource patch size and (3) resource accessibility in a heterogeneous landscape affected host exploitation patterns.\r\nMethods: We quantified nectar robbing by insects in the genus Bombus (bumblebees) and seed predation by Brachypterolus vestitus larvae (Antirrhinum beetle) on Antirrhinum majus L. (wild snapdragons) in the Pyrenees Mountains, Catalonia, Spain. We tested hypotheses about resource exploitation by integrating spatial analyses at multiple scales.\r\nResults: Both trophic interactions were aggregated, explained by the aggregation of their resource. At some scales, nectar robbing is more aggregated than the resource. Trophic interaction abundance is proportional to resource patch size, following the ideal free distribution model. Landscape features do not explain the locations exploited. Nectar robbing and seed predation occur together more often than expected.\r\nConclusions: Our findings suggest that multiple biotic and ecological spatial factors may simultaneously affect resource exploitation at a local scale. These findings should be considered when developing agricultural projects, management plans and conservation policies.","lang":"eng"}],"publication_status":"published","date_created":"2024-09-08T22:01:11Z","department":[{"_id":"NiBa"}],"external_id":{"isi":["001304011900001"]},"language":[{"iso":"eng"}],"corr_author":"1","acknowledgement":"For the beetle barcoding, we are very thankful to Brent Emerson’s laboratory at the Consejo Superior de Investigaciones Científicas (CSIC) at the Instituto de Productos Naturales y Agrobiología (IPNA) in La Laguna, Tenerife.

Our focus is on systems where isotropic or anisotropic impurity-boson interactions support a shallow bound state. To study the fate of the angulon in the vicinity of bound-state formation, we formulate a beyond-linear-coupling angulon Hamiltonian. First, we use it to study attractive, spherically symmetric impurity-boson interactions for which the linear rotor can be mapped onto a static impurity. The well-known polaron formalism provides an adequate description in this limit. Second, we consider anisotropic potentials, and show that the presence of a shallow bound state with pronounced anisotropic character leads to a many-body instability that washes out the angulon dynamics."}]},{"article_processing_charge":"No","citation":{"mla":"Dello Schiavo, Lorenzo, et al. “Scaling Limits of Random Walks, Harmonic Profiles, and Stationary Nonequilibrium States in Lipschitz Domains.” <i>Annals of Applied Probability</i>, vol. 34, no. 2, Institute of Mathematical Statistics, 2024, pp. 1789–845, doi:<a href=\"https://doi.org/10.1214/23-AAP2007\">10.1214/23-AAP2007</a>.","short":"L.

Chemical changes that occur during each one of these steps render them performance determining. Particularly the purification steps, bypassed in conventional solid-state synthesis, are the cause for large discrepancies among similar solution-processed materials. In present work, the investigation focuses on a water-based surfactant free solution synthesis of SnSe, a highly relevant thermoelectric material. We show and rationalize that the number of leaching steps, purification solvent, annealing, and annealing atmosphere have significant influence on the Sn : Se ratio and impurity content in the powder. Such compositional changes that are undetectable by conventional characterization techniques lead to distinct consolidated materials with different types and concentration of defects. Additionally, the profound effect on their transport properties is demonstrated. We emphasize that understanding the chemistry and identifying key chemical species and their role throughout the process is paramount for optimizing material performance. Furthermore, we aim to demonstrate the necessity of comprehensive reporting of these steps as a standard practice to ensure material reproducibility."}],"article_number":"e202402628","acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"NMR"},{"_id":"LifeSc"}],"author":[{"full_name":"Fiedler, Christine","last_name":"Fiedler","id":"bd3fceba-dc74-11ea-a0a7-c17f71817366","first_name":"Christine"},{"orcid":"0000-0003-4566-5877","last_name":"Calcabrini","full_name":"Calcabrini, Mariano","id":"45D7531A-F248-11E8-B48F-1D18A9856A87","first_name":"Mariano"},{"orcid":"0000-0001-7313-6740","full_name":"Liu, Yu","last_name":"Liu","id":"2A70014E-F248-11E8-B48F-1D18A9856A87","first_name":"Yu"},{"first_name":"Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87","full_name":"Ibáñez, Maria","last_name":"Ibáñez","orcid":"0000-0001-5013-2843"}],"scopus_import":"1","file_date_updated":"2025-01-09T09:12:07Z","publication":"Angewandte Chemie - International Edition","ec_funded":1,"isi":1,"intvolume":"        63","file":[{"success":1,"relation":"main_file","access_level":"open_access","date_created":"2025-01-09T09:12:07Z","file_id":"18797","file_name":"2024_AngewChemieIntern_Fiedler.pdf","creator":"dernst","file_size":16347226,"checksum":"1572a0f4d2df55751761efeb2d11c7fc","content_type":"application/pdf","date_updated":"2025-01-09T09:12:07Z"}],"acknowledgement":"ISTA and the Werner Siemens Foundation financially supported this work.

In their work, Niyogi, Smale, and Weinberger studied samples of C² manifolds with positive reach embedded in ℝ^d. We extend their results in the following ways: - As the ambient space we consider both ℝ^d and Riemannian manifolds with lower bounded sectional curvature. - In both types of ambient spaces, we study sets of positive reach - a significantly more general setting than C² manifolds - as well as general manifolds of positive reach. - The sample P of a set (or a manifold) 𝒮 of positive reach may be noisy. We work with two one-sided Hausdorff distances - ε and δ - between P and 𝒮. We provide tight bounds in terms of ε and δ, that guarantee that there exists a parameter r such that the union of balls of radius r centred at the sample P deformation-retracts to 𝒮. We exhibit their tightness by an explicit construction. We carefully distinguish the roles of δ and ε. This is not only essential to achieve tight bounds, but also sensible in practical situations, since it allows one to adapt the bound according to sample density and the amount of noise present in the sample separately."}],"publication_status":"published","department":[{"_id":"GradSch"},{"_id":"HeEd"}],"external_id":{"arxiv":["2206.10485"]},"date_created":"2024-06-25T11:45:58Z","language":[{"iso":"eng"}],"file":[{"access_level":"open_access","relation":"main_file","success":1,"content_type":"application/pdf","checksum":"6a2ddc8b51aa58f197a8b294750f1f8d","date_updated":"2024-06-25T11:47:26Z","file_name":"LIPIcs.SoCG.2024.11.pdf","creator":"cfillmor","date_created":"2024-06-25T11:47:26Z","file_id":"17171","file_size":20886142}],"acknowledgement":"This research has been supported by the European Research Council (ERC), grant No. 788183, by the Wittgenstein Prize, Austrian Science Fund (FWF), grant No. Z 342-N31, and by the DFG Collaborative Research Center TRR 109, Austrian Science Fund (FWF), grant No. I 02979-N35.\r\nWintraecken, Mathijs: Supported by the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No. 754411, the Austrian science fund (FWF) grant No. M-3073, and the welcome package from IDEX of the Université Côte d'Azur.","oa":1,"publication_identifier":{"eissn":["1868-8969"],"isbn":["9783959773164"]},"scopus_import":"1","author":[{"last_name":"Attali","full_name":"Attali, Dominique","first_name":"Dominique"},{"full_name":"Kourimska, Hana","last_name":"Kourimska","id":"D9B8E14C-3C26-11EA-98F5-1F833DDC885E","first_name":"Hana","orcid":"0000-0001-7841-0091"},{"last_name":"Fillmore","full_name":"Fillmore, Christopher D","id":"35638A5C-AAC7-11E9-B0BF-5503E6697425","first_name":"Christopher D"},{"first_name":"Ishika","id":"ee449b28-344d-11ef-a6d5-9ca430e9e9ff","full_name":"Ghosh, Ishika","last_name":"Ghosh"},{"full_name":"Lieutier, André","last_name":"Lieutier","first_name":"André"},{"orcid":"0000-0002-6862-208X","id":"2D04F932-F248-11E8-B48F-1D18A9856A87","first_name":"Elizabeth R","last_name":"Stephenson","full_name":"Stephenson, Elizabeth R"},{"orcid":"0000-0002-7472-2220","last_name":"Wintraecken","full_name":"Wintraecken, Mathijs","id":"307CFBC8-F248-11E8-B48F-1D18A9856A87","first_name":"Mathijs"}],"file_date_updated":"2024-06-25T11:47:26Z","publication":"40th International Symposium on Computational Geometry","ec_funded":1,"intvolume":"       293"}]
