But as orbits become increasingly crowded with both satellites and inevitable space debris pollution, continued operations become endangered by the heightened risks of debris collisions in orbit. Kessler Syndrome is the term for when a critical threshold of orbiting debris triggers a runaway positive feedback loop of debris collisions, creating debris congestion that can render orbits unusable. As this potential tipping point becomes more widely recognized, there have been renewed calls for debris mitigation and removal. Here, we combine complex systems and social-ecological systems approaches to study how these efforts may affect space debris accumulation and the likelihood of reaching Kessler Syndrome. Specifically, we model how debris levels are affected by future launch rates, cleanup activities, and collisions between extant debris. We contextualize and interpret our dynamic model within a discussion of existing space debris governance and other social, economic, and geopolitical factors that may influence effective collective management of the orbital commons. In line with previous studies, our model finds that debris congestion may be reached in less than 200 years, though a holistic management strategy combining removal and mitigation actions can avoid such outcomes while continuing space activities. Moreover, although active debris removal may be particularly effective, the current lack of market and governance support may impede its implementation. Research into these critical dynamics and the multi-faceted variables that influence debris outcomes can support policymakers in curating impactful governance strategies and realistic transition pathways to sustaining debris-free orbits. Overall, our study is useful for communicating about space debris sustainability in policy and education settings by providing an exploration of policy portfolio options supported by a simple and clear social-ecological modeling approach."}],"_id":"14901","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","intvolume":" 18","title":"Tipping points of space debris in low earth orbit","status":"public","ddc":["550"],"oa_version":"Published Version","file":[{"relation":"main_file","file_id":"14939","checksum":"b80ebc889033c365d8f8c05a0c655382","success":1,"date_created":"2024-02-05T10:06:35Z","date_updated":"2024-02-05T10:06:35Z","access_level":"open_access","file_name":"2023_IntJourCommons_Nomura.pdf","content_type":"application/pdf","file_size":1305786,"creator":"dernst"}]},{"day":"23","article_processing_charge":"No","scopus_import":"1","date_published":"2024-01-23T00:00:00Z","article_type":"original","publication":"Journal of Nonlinear Science","citation":{"ama":"Davoli E, D’Elia L, Ingmanns J.

Despite their stability, centrioles can disappear during differentiation, such as in oocytes, but little is known about the regulation of their structural integrity. Our previous research revealed that the pericentriolar material (PCM) that surrounds centrioles and its recruiter, Polo kinase, are downregulated in oogenesis and sufficient for maintaining both centrosome structural integrity and MTOC activity. We now show that the expression of specific components of the centriole cartwheel and wall, including ANA1/CEP295, is essential for maintaining centrosome integrity. We find that Polo kinase requires ANA1 to promote centriole stability in cultured cells and eggs. In addition, ANA1 expression prevents the loss of centrioles observed upon PCM-downregulation. However, the centrioles maintained by overexpressing and tethering ANA1 are inactive, unlike the MTOCs observed upon tethering Polo kinase. These findings demonstrate that several centriole components are needed to maintain centrosome structure. Our study also highlights that centrioles are more dynamic than previously believed, with their structural stability relying on the continuous expression of multiple components."}],"issue":"1","_id":"14933","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","status":"public","title":"Ana1/CEP295 is an essential player in the centrosome maintenance program regulated by Polo kinase and the PCM","ddc":["570"],"intvolume":" 25","file":[{"date_updated":"2024-02-05T12:35:03Z","date_created":"2024-02-05T12:35:03Z","success":1,"checksum":"53c3ef43d9bd6d7bff3ffcf57d763cac","file_id":"14941","relation":"main_file","creator":"dernst","file_size":9645056,"content_type":"application/pdf","file_name":"2023_EmboReports_PimentaMarques.pdf","access_level":"open_access"}],"oa_version":"Published Version","scopus_import":"1","day":"10","article_processing_charge":"Yes (in subscription journal)","has_accepted_license":"1","publication":"EMBO reports","citation":{"mla":"Pimenta-Marques, Ana, et al. “Ana1/CEP295 Is an Essential Player in the Centrosome Maintenance Program Regulated by Polo Kinase and the PCM.” EMBO Reports, vol. 25, no. 1, Embo Press, 2024, pp. 102–27, doi:10.1038/s44319-023-00020-6.","short":"A.

In the 1970s, Stephen Jay Gould presented the first extensive data on antler size in the Irish elk and combined these with comparative data from other deer to test the hypothesis that the gigantic antlers were the outcome of a positive allometry that constrained large-bodied deer to have proportionally even larger antlers. He concluded that the Irish elk had antlers as predicted for its size and interpreted this within his emerging framework of developmental constraints as an explanatory factor in evolution. Here we reanalyze antler allometry based on new morphometric data for 57 taxa of the family Cervidae. We also present a new phylogeny for the Cervidae, which we use for comparative analyses. In contrast to Gould, we find that the antlers of Irish elk were larger than predicted from the allometry within the true deer, Cervini, as analyzed by Gould, but follow the allometry across Cervidae as a whole. After dissecting the discrepancy, we reject the allometric-constraint hypothesis because, contrary to Gould, we find no similarity between static and evolutionary allometries, and because we document extensive non-allometric evolution of antler size across the Cervidae."}],"type":"journal_article"},{"date_published":"2024-01-26T00:00:00Z","doi":"10.1007/s11118-023-10118-0","language":[{"iso":"eng"}],"publication":"Potential Analysis","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1007/s11118-023-10118-0"}],"oa":1,"citation":{"chicago":"Dello Schiavo, Lorenzo, Eva Kopfer, and Karl Theodor Sturm. “A Discovery Tour in Random Riemannian Geometry.” Potential Analysis.

The fundamental processes are conceptually well understood, though the magnitudes of cooling and presence of glacier winds are poorly quantified in space and time, increasing the forcing uncertainty for melt models. We utilize a new data set of on-glacier meteorological measurements on three neighboring glaciers in the Swiss Alps to explore their distinct response to regional climate under the extreme 2022 summer. We find that synoptic wind origins and local terrain modifications, not only glacier size, play an important role in the ability of a glacier to cool the near-surface air. Warm air intrusions from valley or synoptically-driven winds onto the glacier can occur between ∼19% and 64% of the time and contribute between 3% and 81% of the total sensible heat flux to the surface during warm afternoon hours, depending on the fetch of the glacier flowline and its susceptibility to boundary layer erosion. In the context of extreme summer warmth, indicative of future conditions, the boundary layer cooling (up to 6.5°C cooler than its surroundings) and resultant katabatic wind flow are highly heterogeneous between the study glaciers, highlighting the complex and likely non-linear response of glaciers to an uncertain future.","lang":"eng"}],"issue":"2","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"14885","status":"public","title":"Local controls on near-surface glacier cooling under warm atmospheric conditions","ddc":["550"],"intvolume":" 129","oa_version":"Published Version","file":[{"file_id":"14943","relation":"main_file","success":1,"checksum":"cad5b93caadb40c14e5faedc34f7bba7","date_updated":"2024-02-06T08:38:27Z","date_created":"2024-02-06T08:38:27Z","access_level":"open_access","file_name":"2024_JGRAtmospheres_Shaw.pdf","creator":"dernst","content_type":"application/pdf","file_size":7481087}],"month":"01","publication_identifier":{"eissn":["2169-8996"],"issn":["2169-897X"]},"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"},"oa":1,"quality_controlled":"1","doi":"10.1029/2023JD040214","language":[{"iso":"eng"}],"article_number":"e2023JD040214","file_date_updated":"2024-02-06T08:38:27Z","acknowledgement":"This project has received funding from the European Union's Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No. 101026058.

In High Mountain Asia (HMA), where a wide range of climates from semi-arid to monsoonal exist, the importance of the cryospheric contributions to the water budget varies with the amount and seasonal distribution of precipitation. Losses due to evapotranspiration and sublimation are to date largely unquantified components of the water budget in such catchments, although they can be comparable in magnitude to glacier melt contributions to streamflow. 
Here, we simulate the hydrology of three high elevation headwater catchments in distinct climates in HMA over 10 years using an ecohydrological model geared towards high-mountain areas including snow and glaciers, forced with reanalysis data. 
Our results show that evapotranspiration and sublimation together are most important at the semi-arid site, Kyzylsu, on the northernmost slopes of the Pamir mountain range. Here, the evaporative loss amounts to 28% of the water throughput, which we define as the total water added to, or removed from the water balance within a year. In comparison, evaporative losses are 19% at the Central Himalayan site Langtang and 13% at the wettest site, 24K, on the Southeastern Tibetan Plateau. At the three sites, respectively, sublimation removes 15%, 13% and 6% of snowfall, while evapotranspiration removes the equivalent of 76%, 28% and 19% of rainfall. In absolute terms, and across a comparable elevation range, the highest ET flux is 413 mm yr-1 at 24K, while the highest sublimation flux is 91 mm yr-1 at Kyzylsu. During warm and dry years, glacier melt was found to only partially compensate for the annual supply deficit.","lang":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"14938","ddc":["550"],"title":"Hydrological regimes and evaporative flux partitioning at the climatic ends of High Mountain Asia","status":"public","oa_version":"Published Version"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"14213","year":"2024","ddc":["000"],"title":"Divided attention: Unsupervised multi-object discovery with contextually separated slots","status":"public","publication_status":"published","department":[{"_id":"FrLo"}],"author":[{"full_name":"Lao, Dong","last_name":"Lao","first_name":"Dong"},{"last_name":"Hu","first_name":"Zhengyang","full_name":"Hu, Zhengyang"},{"first_name":"Francesco","last_name":"Locatello","id":"26cfd52f-2483-11ee-8040-88983bcc06d4","orcid":"0000-0002-4850-0683","full_name":"Locatello, Francesco"},{"full_name":"Yang, Yanchao","last_name":"Yang","first_name":"Yanchao"},{"full_name":"Soatto, Stefano","first_name":"Stefano","last_name":"Soatto"}],"date_created":"2023-08-22T14:19:59Z","date_updated":"2024-02-12T08:56:23Z","file":[{"content_type":"application/pdf","file_size":8038511,"creator":"dernst","file_name":"2024_CPAL_Lao.pdf","access_level":"open_access","date_created":"2024-02-12T08:40:36Z","date_updated":"2024-02-12T08:40:36Z","checksum":"8fad894c34f1b3d5a14fb8ffb12f7277","success":1,"relation":"main_file","file_id":"14978"}],"oa_version":"Published Version","type":"conference","abstract":[{"lang":"eng","text":"We introduce a method to segment the visual field into independently moving regions, trained with no ground truth or supervision. It consists of an adversarial conditional encoder-decoder architecture based on Slot Attention, modified to use the image as context to decode optical flow without attempting to reconstruct the image itself. In the resulting multi-modal representation, one modality (flow) feeds the encoder to produce separate latent codes (slots), whereas the other modality (image) conditions the decoder to generate the first (flow) from the slots. This design frees the representation from having to encode complex nuisance variability in the image due to, for instance, illumination and reflectance properties of the scene. Since customary autoencoding based on minimizing the reconstruction error does not preclude the entire flow from being encoded into a single slot, we modify the loss to an adversarial criterion based on Contextual Information Separation. The resulting min-max optimization fosters the separation of objects and their assignment to different attention slots, leading to Divided Attention, or DivA. DivA outperforms recent unsupervised multi-object motion segmentation methods while tripling run-time speed up to 104FPS and reducing the performance gap from supervised methods to 12% or less. DivA can handle different numbers of objects and different image sizes at training and test time, is invariant to permutation of object labels, and does not require explicit regularization."}],"file_date_updated":"2024-02-12T08:40:36Z","publication":"1st Conference on Parsimony and Learning","external_id":{"arxiv":["2304.01430"]},"oa":1,"citation":{"chicago":"Lao, Dong, Zhengyang Hu, Francesco Locatello, Yanchao Yang, and Stefano Soatto. “Divided Attention: Unsupervised Multi-Object Discovery with Contextually Separated Slots.” In 1st Conference on Parsimony and Learning, 2024.","short":"D.

Torsional oscillators present an opportunity in this regard due to their remarked isolation from environmental noise. For torsional motion, an effective employment of optical cavities to enhance optomechanical interactions—as already established for linear oscillators—so far faced certain challenges. Here, we propose a concept for sensing and manipulating torsional motion, where exclusively the torsional rotations of a pendulum are mapped onto the path length of a single two-mirror optical cavity. The concept inherently alleviates many limitations of previous approaches. A proof-of-principle experiment is conducted with a rigidly controlled pendulum to explore the sensing aspects of the concept and to identify practical limitations in a potential state-of-the art setup. Based on this study, we anticipate development of precision torque sensors utilizing torsional pendulums that can support sensitivities below 10−19Nm/√Hz, while the motion of the pendulums are dominated by quantum radiation pressure noise at sub-microwatts of incoming laser power. These developments will provide horizons for experiments at the interface of quantum mechanics and gravity.","lang":"eng"}],"issue":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"14980","status":"public","title":"Zigzag optical cavity for sensing and controlling torsional motion","ddc":["530"],"intvolume":" 6","file":[{"access_level":"open_access","file_name":"2024_PhysicalRevResearch_Agafonova.pdf","content_type":"application/pdf","file_size":1437167,"creator":"dernst","relation":"main_file","file_id":"14981","checksum":"3a39ebffb24c1cc1dd0b547a726dc52d","success":1,"date_created":"2024-02-12T11:46:50Z","date_updated":"2024-02-12T11:46:50Z"}],"oa_version":"Published Version","day":"05","has_accepted_license":"1","article_processing_charge":"Yes","publication":"Physical Review Research","citation":{"ieee":"S.

Amphibians, with their unique phylogenetic position at the transition between aquatic and terrestrial lifestyles, are valuable for understanding the origin and evolution of the tetrapod brain and spinal cord. Their metamorphic developmental transitions and unique regenerative abilities also facilitate the discovery of mechanisms for neural circuit remodeling and replacement. The genetic toolkit for amphibians, however, remains limited, with only a few species having sequenced genomes and a small number of transgenic lines available. In mammals, recombinant adeno-associated viral vectors (AAVs) have become a powerful alternative to genome modification for visualizing and perturbing the nervous system. AAVs are DNA viruses that enable neuronal transduction in both developing and adult animals with low toxicity and spatial, temporal, and cell-type specificity. However, AAVs have never been shown to transduce amphibian cells efficiently. To bridge this gap, we established a simple, scalable, and robust strategy to screen AAV serotypes in three distantly-related amphibian species: the frogs Xenopus laevis and Pelophylax bedriagae, and the salamander Pleurodeles waltl, in both developing larval tadpoles and post-metamorphic animals. For each species, we successfully identified at least two AAV serotypes capable of infecting the CNS; however, no pan-amphibian serotype was identified, indicating rapid evolution of AAV tropism. In addition, we developed an AAV-based strategy that targets isochronic cohorts of developing neurons – a critical tool for parsing neural circuit assembly. Finally, to enable visualization and manipulation of neural circuits, we identified AAV variants for retrograde tracing of neuronal projections in adult animals. Our findings expand the toolkit for amphibians to include AAVs, establish a generalizable workflow for AAV screening in non-canonical research organisms, generate testable hypotheses for the evolution of AAV tropism, and lay the foundation for modern cross-species comparisons of vertebrate CNS development, function, and evolution.

They have wide applications ranging from computer science to economics and biology. Yet, even though an agent’s payoff only depends on the actions of their direct neighbors in graphical games, computing the Nash equilibria and making statements about the convergence time of \"natural\" local dynamics in particular can be highly challenging. In this work, we present a novel approach for classifying complexity of Nash equilibria in graphical games by establishing a connection to local graph algorithms, a subfield of distributed computing. In particular, we make the observation that the equilibria of graphical games are equivalent to locally verifiable labelings (LVL) in graphs; vertex labelings which are verifiable with constant-round local algorithms. This connection allows us to derive novel lower bounds on the convergence time to equilibrium of best-response dynamics in graphical games. Since we establish that distributed convergence can sometimes be provably slow, we also introduce and give bounds on an intuitive notion of \"time-constrained\" inefficiency of best responses. We exemplify how our results can be used in the implementation of mechanisms that ensure convergence of best responses to a Nash equilibrium. Our results thus also give insight into the convergence of strategy-proof algorithms for graphical games, which is still not well understood.","lang":"eng"}],"type":"conference","alternative_title":["LIPIcs"],"oa_version":"Published Version","file":[{"access_level":"open_access","file_name":"2024_LIPICs_Hirvonen.pdf","creator":"dernst","content_type":"application/pdf","file_size":867363,"file_id":"15028","relation":"main_file","success":1,"checksum":"4fc7eea6e4ba140b904781fc7df868ec","date_created":"2024-02-26T09:04:58Z","date_updated":"2024-02-26T09:04:58Z"}],"_id":"15006","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","intvolume":" 286","status":"public","title":"On the convergence time in graphical games: A locality-sensitive approach","ddc":["000"],"publication_identifier":{"issn":["18688969"],"isbn":["9783959773089"]},"month":"01","doi":"10.4230/LIPIcs.OPODIS.2023.11","conference":{"location":"Tokyo, Japan","start_date":"2023-12-06","end_date":"2023-12-08","name":"OPODIS: Conference on Principles of Distributed Systems"},"language":[{"iso":"eng"}],"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":{"arxiv":["2102.13457"]},"oa":1,"project":[{"grant_number":"863818","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","call_identifier":"H2020","name":"Formal Methods for Stochastic Models: Algorithms and Applications"}],"quality_controlled":"1","ec_funded":1,"file_date_updated":"2024-02-26T09:04:58Z","article_number":"11","author":[{"last_name":"Hirvonen","first_name":"Juho","full_name":"Hirvonen, Juho"},{"full_name":"Schmid, Laura","id":"38B437DE-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6978-7329","first_name":"Laura","last_name":"Schmid"},{"id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4561-241X","first_name":"Krishnendu","last_name":"Chatterjee","full_name":"Chatterjee, Krishnendu"},{"full_name":"Schmid, Stefan","first_name":"Stefan","last_name":"Schmid"}],"volume":286,"date_created":"2024-02-18T23:01:01Z","date_updated":"2024-02-26T09:16:12Z","year":"2024","acknowledgement":"This work was partially funded by the Academy of Finland, grant 314888, the European Research Council CoG 863818 (ForM-SMArt), and the Austrian Science Fund (FWF) project I 4800-N (ADVISE).

Existing oblivious routing schemes with polylogarithmic competitive ratio for general networks are tree-based, in the sense that routing is performed according to a convex combination of trees. However, this restriction to trees leads to a construction that has time quadratic in the size of the network and does not parallelize well. \r\nIn this paper we study oblivious routing schemes based on electrical routing. In particular, we show that general networks with n vertices and m edges admit a routing scheme that has competitive ratio O(log² n) and consists of a convex combination of only O(√m) electrical routings. This immediately leads to an improved construction algorithm with time Õ(m^{3/2}) that can also be implemented in parallel with Õ(√m) depth.","lang":"eng"}],"alternative_title":["LIPIcs"],"type":"conference","language":[{"iso":"eng"}],"conference":{"end_date":"2024-02-02","start_date":"2024-01-30","location":"Berkeley, CA, United States","name":"ITCS: Innovations in Theoretical Computer Science Conference"},"doi":"10.4230/LIPIcs.ITCS.2024.55","quality_controlled":"1","project":[{"name":"The design and evaluation of modern fully dynamic data structures","call_identifier":"H2020","_id":"bd9ca328-d553-11ed-ba76-dc4f890cfe62","grant_number":"101019564"},{"name":"Wittgenstein Award - Monika Henzinger","grant_number":"Z00422","_id":"34def286-11ca-11ed-8bc3-da5948e1613c"},{"grant_number":"I05982","_id":"bda196b2-d553-11ed-ba76-8e8ee6c21103","name":"Static and Dynamic Hierarchical Graph Decompositions"},{"name":"Fast Algorithms for a Reactive Network Layer","grant_number":"P33775 ","_id":"bd9e3a2e-d553-11ed-ba76-8aa684ce17fe"}],"external_id":{"arxiv":["2303.02491"]},"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"},"oa":1,"month":"01","publication_identifier":{"issn":["1868-8969"],"isbn":["9783959773096"]},"date_created":"2024-02-18T23:01:02Z","date_updated":"2024-02-26T10:12:19Z","volume":287,"author":[{"last_name":"Goranci","first_name":"Gramoz","full_name":"Goranci, Gramoz"},{"full_name":"Henzinger, Monika H","last_name":"Henzinger","first_name":"Monika H","orcid":"0000-0002-5008-6530","id":"540c9bbd-f2de-11ec-812d-d04a5be85630"},{"full_name":"Räcke, Harald","last_name":"Räcke","first_name":"Harald"},{"last_name":"Sachdeva","first_name":"Sushant","full_name":"Sachdeva, Sushant"},{"first_name":"A.

This constitutes a major flaw discovered with the introduction of decentralized finance and allows miners to perform MEV attacks. In this paper, we address the issue of sandwich attacks by providing a construction that takes as input a blockchain protocol and outputs a new blockchain protocol with the same security but in which sandwich attacks are not profitable. Furthermore, our protocol is fully decentralized with no trusted third parties or heavy cryptography primitives and carries a linear increase in latency and minimum computation overhead."}],"type":"conference","alternative_title":["LIPIcs"],"file":[{"file_id":"15031","relation":"main_file","success":1,"checksum":"2993e810a45e8c8056106834b07aea92","date_updated":"2024-02-26T10:16:57Z","date_created":"2024-02-26T10:16:57Z","access_level":"open_access","file_name":"2024_LIPICs_Alpos.pdf","creator":"dernst","content_type":"application/pdf","file_size":1505994}],"oa_version":"Published Version","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"15007","intvolume":" 286","ddc":["000"],"status":"public","title":"Eating sandwiches: Modular and lightweight elimination of transaction reordering attacks","article_processing_charge":"No","has_accepted_license":"1","day":"18","scopus_import":"1","date_published":"2024-01-18T00:00:00Z","citation":{"mla":"Alpos, Orestis, et al. “Eating Sandwiches: Modular and Lightweight Elimination of Transaction Reordering Attacks.” 27th International Conference on Principles of Distributed Systems, vol. 286, 12, Schloss Dagstuhl - Leibniz-Zentrum für Informatik, 2024, doi:10.4230/LIPIcs.OPODIS.2023.12.","short":"O.
