Yet, existing efforts are largely limited to simple synthetic settings that are far away from real-world problems. In this paper, we present Causal Triplet, a causal representation learning benchmark featuring not only visually more complex scenes, but also two crucial desiderata commonly overlooked in previous works: (i) an actionable counterfactual setting, where only certain object-level variables allow for counterfactual observations whereas others do not; (ii) an interventional downstream task with an emphasis on out-of-distribution robustness from the independent causal mechanisms principle. Through extensive experiments, we find that models built with the knowledge of disentangled or object-centric representations significantly outperform their distributed counterparts. However, recent causal representation learning methods still struggle to identify such latent structures, indicating substantial challenges and opportunities for future work.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2301.05169"}],"date_created":"2023-08-22T14:20:18Z","extern":"1","publication_status":"published","title":"Causal triplet: An open challenge for intervention-centric causal representation learning","date_updated":"2024-10-14T12:30:42Z","external_id":{"arxiv":["2301.05169"]},"date_published":"2023-04-12T00:00:00Z","_id":"14214","arxiv":1,"status":"public","oa_version":"Preprint","oa":1,"month":"04"},{"quality_controlled":"1","abstract":[{"text":"CLIP proved that aligning visual and language spaces is key to solving many vision tasks without explicit training, but required to train image and text encoders from scratch on a huge dataset. LiT improved this by only training the text encoder and using a pre-trained vision network. In this paper, we show that a common space can be created without any training at all, using single-domain encoders (trained with or without supervision) and a much smaller amount of image-text pairs. Furthermore, our model has unique properties. Most notably, deploying a new version with updated training samples can be done in a matter of seconds. Additionally, the representations in the common space are easily interpretable as every dimension corresponds to the similarity of the input to a unique entry in the multimodal dataset. Experiments on standard zero-shot visual benchmarks demonstrate the typical transfer ability of image-text models. Overall, our method represents a simple yet surprisingly strong baseline for foundation multi-modal models, raising important questions on their data efficiency and on the role of retrieval in machine learning.","lang":"eng"}],"external_id":{"arxiv":["2210.01738"]},"date_published":"2023-10-04T00:00:00Z","publication_status":"published","title":"ASIF: Coupled data turns unimodal models to multimodal without training","date_updated":"2025-05-14T11:28:52Z","arxiv":1,"corr_author":"1","publication_identifier":{"isbn":["9781713899921"]},"publication":"37th Conference on Neural Information Processing Systems","citation":{"ama":"Norelli A, Fumero M, Maiorca V, Moschella L, Rodolà E, Locatello F.

Ideally, the distribution of the data points in the latent space should depend only on the task, the data, the loss, and other architecture-specific constraints. However, factors such as the random weights initialization, training hyperparameters, or other sources of randomness in the training phase may induce incoherent latent spaces that hinder any form of reuse. Nevertheless, we empirically observe that, under the same data and modeling choices, the angles between the encodings within distinct latent spaces do not change. In this work, we propose the latent similarity between each sample and a fixed set of anchors as an alternative data representation, demonstrating that it can enforce the desired invariances without any additional training. We show how neural architectures can leverage these relative representations to guarantee, in practice, invariance to latent isometries and rescalings, effectively enabling latent space communication: from zero-shot model stitching to latent space comparison between diverse settings. We extensively validate the generalization capability of our approach on different datasets, spanning various modalities (images, text, graphs), tasks (e.g., classification, reconstruction) and architectures (e.g., CNNs, GCNs, transformers).","lang":"eng"}],"quality_controlled":"1","main_file_link":[{"url":"https://arxiv.org/abs/2209.15430","open_access":"1"}],"author":[{"full_name":"Moschella, Luca","last_name":"Moschella","first_name":"Luca"},{"last_name":"Maiorca","full_name":"Maiorca, Valentino","first_name":"Valentino"},{"last_name":"Fumero","full_name":"Fumero, Marco","first_name":"Marco"},{"full_name":"Norelli, Antonio","last_name":"Norelli","first_name":"Antonio"},{"first_name":"Francesco","id":"26cfd52f-2483-11ee-8040-88983bcc06d4","orcid":"0000-0002-4850-0683","full_name":"Locatello, Francesco","last_name":"Locatello"},{"last_name":"Rodolà","full_name":"Rodolà, Emanuele","first_name":"Emanuele"}]},{"citation":{"apa":"Seitzer, M., Horn, M., Zadaianchuk, A., Zietlow, D., Xiao, T., Carl-Johann Simon-Gabriel, C.-J.

In this work, we overcome this limitation by showing that reconstructing features from models trained in a self-supervised manner is a sufficient training signal for object-centric representations to arise in a fully unsupervised way. Our approach, DINOSAUR, significantly out-performs existing image-based object-centric learning models on simulated data and is the first unsupervised object-centric model that scales to real-world datasets such as COCO and PASCAL VOC.

We decompose this problem into three easier subtasks, and provide candidate solutions for each of them. Inspired by the Common Fate Principle of Gestalt Psychology, we first extract (noisy) masks of moving objects via unsupervised motion segmentation. Second, generative models are trained on the masks of the background and the moving objects, respectively. Third, background and foreground models are combined in a conditional \"dead leaves\" scene model to sample novel scene configurations where occlusions and depth layering arise naturally. To evaluate the individual stages, we introduce the Fishbowl dataset positioned between complex real-world scenes and common object-centric benchmarks of simplistic objects. We show that our approach allows learning generative models that generalize beyond the occlusions present in the input videos, and represent scenes in a modular fashion that allows sampling plausible scenes outside the training distribution by permitting, for instance, object numbers or densities not observed in the training set."}],"author":[{"full_name":"Tangemann, Matthias","last_name":"Tangemann","first_name":"Matthias"},{"full_name":"Schneider, Steffen","last_name":"Schneider","first_name":"Steffen"},{"last_name":"Kügelgen","full_name":"Kügelgen, Julius von","first_name":"Julius von"},{"first_name":"Francesco","id":"26cfd52f-2483-11ee-8040-88983bcc06d4","orcid":"0000-0002-4850-0683","full_name":"Locatello, Francesco","last_name":"Locatello"},{"first_name":"Peter","full_name":"Gehler, Peter","last_name":"Gehler"},{"full_name":"Brox, Thomas","last_name":"Brox","first_name":"Thomas"},{"full_name":"Kümmerer, Matthias","last_name":"Kümmerer","first_name":"Matthias"},{"first_name":"Matthias","full_name":"Bethge, Matthias","last_name":"Bethge"},{"first_name":"Bernhard","full_name":"Schölkopf, Bernhard","last_name":"Schölkopf"}],"date_published":"2023-04-15T00:00:00Z","external_id":{"arxiv":["2110.06562"]},"date_updated":"2023-09-13T11:31:14Z","title":"Unsupervised object learning via common fate","publication_status":"published","extern":"1"},{"citation":{"ama":"Kranabetter L, Kristensen HH, Ghazaryan A, et al.

Comparison to alignment dynamics calculated from the time-dependent rotational Schrödinger equation shows that the deviation is due to the alignment dependent interaction between the dimer and the droplet surface. This interaction confines the dimer to the tangential plane of the droplet surface at the point where it resides and is the reason that the observed alignment dynamics is also well described by a 2D quantum rotor model."}],"quality_controlled":"1","publication_identifier":{"eissn":["1079-7114"],"issn":["0031-9007"]},"arxiv":1,"ec_funded":1,"year":"2023","language":[{"iso":"eng"}],"article_type":"original","publisher":"American Physical Society","issue":"5","day":"04","article_processing_charge":"No","department":[{"_id":"MiLe"}],"doi":"10.1103/PhysRevLett.131.053201","scopus_import":"1","intvolume":"       131","author":[{"full_name":"Kranabetter, Lorenz","last_name":"Kranabetter","first_name":"Lorenz"},{"first_name":"Henrik H.","full_name":"Kristensen, Henrik H.","last_name":"Kristensen"},{"id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","first_name":"Areg","last_name":"Ghazaryan","full_name":"Ghazaryan, Areg","orcid":"0000-0001-9666-3543"},{"first_name":"Constant A.","full_name":"Schouder, Constant A.","last_name":"Schouder"},{"first_name":"Adam S.","full_name":"Chatterley, Adam S.","last_name":"Chatterley"},{"first_name":"Paul","full_name":"Janssen, Paul","last_name":"Janssen"},{"first_name":"Frank","full_name":"Jensen, Frank","last_name":"Jensen"},{"last_name":"Zillich","full_name":"Zillich, Robert E.","first_name":"Robert E."},{"full_name":"Lemeshko, Mikhail","last_name":"Lemeshko","orcid":"0000-0002-6990-7802","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail"},{"full_name":"Stapelfeldt, Henrik","last_name":"Stapelfeldt","first_name":"Henrik"}],"main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2308.15247","open_access":"1"}],"volume":131,"date_created":"2023-08-27T22:01:16Z","oa":1,"month":"08","_id":"14238","oa_version":"Preprint","status":"public","article_number":"053201"},{"day":"03","article_type":"original","publisher":"Cambridge University Press","department":[{"_id":"TaHa"}],"article_processing_charge":"Yes","has_accepted_license":"1","year":"2023","language":[{"iso":"eng"}],"month":"08","oa":1,"article_number":"e66","ddc":["510"],"_id":"14239","file_date_updated":"2023-09-05T06:43:11Z","status":"public","oa_version":"Published Version","intvolume":"        11","doi":"10.1017/fms.2023.65","scopus_import":"1","volume":11,"date_created":"2023-08-27T22:01:16Z","author":[{"id":"2cf70c34-09c1-11ed-bd8d-c34fac206130","first_name":"Mirko","last_name":"Mauri","full_name":"Mauri, Mirko"},{"first_name":"Evgeny","full_name":"Shinder, Evgeny","last_name":"Shinder"}],"file":[{"checksum":"c36241750cc5cb06890aec0ecdfee626","relation":"main_file","content_type":"application/pdf","file_size":280865,"file_id":"14266","access_level":"open_access","creator":"dernst","date_updated":"2023-09-05T06:43:11Z","success":1,"file_name":"2023_ForumMathematics_Mauri.pdf","date_created":"2023-09-05T06:43:11Z"}],"type":"journal_article","acknowledgement":"We thank Agnieszka Bodzenta-Skibińska, Paolo Cascini, Wahei Hara, Sándor Kovács, Alexander Kuznetsov, Mircea Musta  ă, Nebojsa Pavic, Pavel Sechin, and Michael Wemyss for discussions and e-mail correspondence.

We then solve the two wave regimes separately using appropriate state-of-the-art techniques, and re-combine the resulting wave velocities at the end of each step. This strategy leads to the first heightfield wave model capable of simulating complex interactions between both deep and shallow water effects, like the waves from a boat wake sloshing up onto a beach, or a dam break producing wave interference patterns and eddies.

The naïve optimization of the mesh vertices using the gradients of reflectivity simulations results in undesirable distortion. In contrast, our robust formulation optimizes the surface normal as an independent variable that bridges the reflectivity term with differential rendering, and the regularization term with as-rigid-as-possible elastic energy. We further adaptively subdivide the input mesh to improve the convergence. Consequently, our method can minimize the retroreflectivity of a wide range of input shapes, resulting in sharply creased shapes ubiquitous among stealth aircraft and Sci-Fi vehicles. Furthermore, by changing the reward for the direction of the outgoing light directions, our method can be applied to other reflectivity design tasks, such as the optimization of architectural walls to concentrate light in a specific region. We have tested the proposed method using light-transport simulations and real-world 3D-printed objects.","lang":"eng"}],"quality_controlled":"1","date_updated":"2025-09-09T12:49:15Z","publication_status":"published","title":"Stealth shaper: Reflectivity optimization as surface stylization","isi":1,"external_id":{"isi":["001117690500020"],"arxiv":["2305.05944"]},"date_published":"2023-07-23T00:00:00Z","type":"conference","acknowledgement":"The authors would like to thank Yuki Koyama and Takeo Igarashi for early discussions, and Yuta Yaguchi for support in 3D printing.

Quantization is a technique for making neural networks more efficient by running them using low-bit integer arithmetic and is therefore commonly adopted in industry. Recent work has shown that floating-point neural networks that have been verified to be robust can become vulnerable to adversarial attacks after quantization, and certification of the quantized representation is necessary to guarantee robustness. In this work, we present quantization-aware interval bound propagation (QA-IBP), a novel method for training robust QNNs. Inspired by advances in robust learning of non-quantized networks, our training algorithm computes the gradient of an abstract representation of the actual network. Unlike existing approaches, our method can handle the discrete semantics of QNNs. Based on QA-IBP, we also develop a complete verification procedure for verifying the adversarial robustness of QNNs, which is guaranteed to terminate and produce a correct answer. Compared to existing approaches, the key advantage of our verification procedure is that it runs entirely on GPU or other accelerator devices. We demonstrate experimentally that our approach significantly outperforms existing methods and establish the new state-of-the-art for training and certifying the robustness of QNNs.","lang":"eng"}],"external_id":{"arxiv":["2211.16187"]},"date_published":"2023-06-26T00:00:00Z","date_updated":"2025-03-31T16:01:08Z","publication_status":"published","title":"Quantization-aware interval bound propagation for training certifiably robust quantized neural networks","project":[{"name":"Vigilant Algorithmic Monitoring of Software","_id":"62781420-2b32-11ec-9570-8d9b63373d4d","call_identifier":"H2020","grant_number":"101020093"},{"grant_number":"863818","call_identifier":"H2020","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","name":"Formal Methods for Stochastic Models: Algorithms and Applications"},{"grant_number":"665385","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","name":"International IST Doctoral Program","call_identifier":"H2020"}],"arxiv":1,"ec_funded":1,"publication_identifier":{"isbn":["9781577358800"]},"page":"14964-14973","language":[{"iso":"eng"}],"year":"2023","department":[{"_id":"ToHe"},{"_id":"KrCh"}],"article_processing_charge":"No","issue":"12","day":"26","publisher":"Association for the Advancement of Artificial Intelligence","date_created":"2023-08-27T22:01:17Z","volume":37,"main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2211.16187","open_access":"1"}],"author":[{"first_name":"Mathias","id":"3DC22916-F248-11E8-B48F-1D18A9856A87","last_name":"Lechner","full_name":"Lechner, Mathias"},{"first_name":"Dorde","id":"294AA7A6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4681-1699","last_name":"Zikelic","full_name":"Zikelic, Dorde"},{"orcid":"0000-0002-4561-241X","full_name":"Chatterjee, Krishnendu","last_name":"Chatterjee","first_name":"Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2985-7724","last_name":"Henzinger","full_name":"Henzinger, Thomas A"},{"full_name":"Rus, Daniela","last_name":"Rus","first_name":"Daniela"}],"intvolume":"        37","scopus_import":"1","doi":"10.1609/aaai.v37i12.26747","oa_version":"Preprint","status":"public","_id":"14242","month":"06","oa":1},{"citation":{"mla":"Avni, Guy, et al. “Bidding Graph Games with Partially-Observable Budgets.” <i>Proceedings of the 37th AAAI Conference on Artificial Intelligence</i>, vol. 37, no. 5, 2023, pp. 5464–71, doi:<a href=\"https://doi.org/10.1609/aaai.v37i5.25679\">10.1609/aaai.v37i5.25679</a>.","ista":"Avni G, Jecker IR, Zikelic D. 2023.

The game proceeds by placing a token on a vertex of a graph, and allowing the players to move it to produce an infinite path, which determines the winner or payoff of the game. Traditionally, the players alternate turns in moving the token. In \"bidding games\", however, the players have budgets and in each turn, an auction (bidding) determines which player moves the token. So far, bidding games have only been studied as full-information games. In this work we initiate the study of partial-information bidding games: we study bidding games in which a player's initial budget is drawn from a known probability distribution. We show that while for some bidding mechanisms and objectives, it is straightforward to adapt the results from the full-information setting to the partial-information setting, for others, the analysis is significantly more challenging, requires new techniques, and gives rise to interesting results. Specifically, we study games with \"mean-payoff\" objectives in combination with \"poorman\" bidding. We construct optimal strategies for a partially-informed player who plays against a fully-informed adversary. We show that, somewhat surprisingly, the \"value\" under pure strategies does not necessarily exist in such games.","lang":"eng"}],"quality_controlled":"1","publication_identifier":{"isbn":["9781577358800"]},"arxiv":1,"ec_funded":1,"year":"2023","language":[{"iso":"eng"}],"page":"5464-5471","issue":"5","day":"27","department":[{"_id":"ToHe"},{"_id":"KrCh"}],"article_processing_charge":"No","intvolume":"        37","doi":"10.1609/aaai.v37i5.25679","scopus_import":"1","volume":37,"date_created":"2023-08-27T22:01:18Z","author":[{"orcid":"0000-0001-5588-8287","full_name":"Avni, Guy","last_name":"Avni","first_name":"Guy","id":"463C8BC2-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Ismael R","id":"85D7C63E-7D5D-11E9-9C0F-98C4E5697425","last_name":"Jecker","full_name":"Jecker, Ismael R"},{"first_name":"Dorde","id":"294AA7A6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4681-1699","last_name":"Zikelic","full_name":"Zikelic, Dorde"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1609/aaai.v37i5.25679"}],"month":"06","oa":1,"_id":"14243","status":"public","oa_version":"Published Version"},{"department":[{"_id":"TaHa"}],"article_processing_charge":"Yes (via OA deal)","has_accepted_license":"1","issue":"4","day":"01","article_type":"original","publisher":"Wiley","page":"958-1027","year":"2023","language":[{"iso":"eng"}],"ddc":["510"],"_id":"14244","file_date_updated":"2024-01-30T12:56:00Z","status":"public","oa_version":"Published Version","month":"10","oa":1,"volume":127,"date_created":"2023-08-27T22:01:18Z","author":[{"id":"4A0666D8-F248-11E8-B48F-1D18A9856A87","first_name":"Tamás","last_name":"Hausel","full_name":"Hausel, Tamás","orcid":"0000-0002-9582-2634"},{"first_name":"Michael Lennox","full_name":"Wong, Michael Lennox","last_name":"Wong"},{"full_name":"Wyss, Dimitri","last_name":"Wyss","first_name":"Dimitri"}],"intvolume":"       127","doi":"10.1112/plms.12555","scopus_import":"1","type":"journal_article","acknowledgement":"We would like to thank Gergely Bérczy, Roger Bielawski, Philip Boalch, Sergey Cherkis, Andrew Dancer, Brent Doran, Eloïse Hamilton, Frances Kirwan, Bernard Leclerc, Emmanuel Letellier, Alessia Mandini, Maxence Mayrand, András Némethi, Szilárd Szabó, and Daisuke Yamakawa for discussions related to the paper.

The domains we focus on are defined as product sets with respect to an Iwasawa decomposition. Several natural diophantine problems can be reduced to counting lattice points in such domains. These include equidistribution of the ratio of the length of the shortest solution (x,y) to the gcd equation bx−ay=1 relative to the length of (a,b), where (a,b) ranges over primitive vectors in a disc whose radius increases, the natural analog of this problem in imaginary quadratic number fields, as well as equidistribution of integral solutions to the diophantine equation defined by an integral Lorentz form in three or more variables. We establish an effective rate of convergence for these equidistribution problems, depending on the size of the spectral gap associated with a suitable lattice subgroup in the isometry group of the relevant hyperbolic space. The main result underlying our discussion amounts to establishing effective joint equidistribution for the horospherical component and the radial component in the Iwasawa decomposition of lattice elements."}],"date_published":"2023-07-26T00:00:00Z","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":{"isi":["001047690500001"],"arxiv":["1612.08215"]},"isi":1,"title":"Horospherical coordinates of lattice points in hyperbolic spaces: Effective counting and equidistribution","publication_status":"published","date_updated":"2024-10-09T21:06:46Z","department":[{"_id":"TiBr"}],"article_processing_charge":"Yes","has_accepted_license":"1","issue":"2","day":"26","publisher":"Mathematical Sciences Publishers","article_type":"original","page":"265-294","year":"2023","language":[{"iso":"eng"}],"file_date_updated":"2023-09-05T07:26:17Z","_id":"14245","ddc":["510"],"oa_version":"Published Version","status":"public","month":"07","oa":1,"volume":324,"date_created":"2023-08-27T22:01:18Z","author":[{"id":"C8B7BF48-8D81-11E9-BCA9-F536E6697425","first_name":"Tal","full_name":"Horesh, Tal","last_name":"Horesh"},{"last_name":"Nevo","full_name":"Nevo, Amos","first_name":"Amos"}],"intvolume":"       324","doi":"10.2140/pjm.2023.324.265","scopus_import":"1"},{"article_number":"224","oa_version":"Published Version","status":"public","_id":"14246","file_date_updated":"2023-09-05T08:45:49Z","ddc":["530"],"month":"08","oa":1,"date_created":"2023-08-28T12:36:49Z","volume":6,"author":[{"full_name":"Brauneis, Fabian","last_name":"Brauneis","first_name":"Fabian"},{"first_name":"Areg","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9666-3543","full_name":"Ghazaryan, Areg","last_name":"Ghazaryan"},{"first_name":"Hans-Werner","full_name":"Hammer, Hans-Werner","last_name":"Hammer"},{"first_name":"Artem","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-0393-5525","last_name":"Volosniev","full_name":"Volosniev, Artem"}],"intvolume":"         6","scopus_import":"1","doi":"10.1038/s42005-023-01281-2","department":[{"_id":"MiLe"}],"has_accepted_license":"1","article_processing_charge":"Yes (via OA deal)","day":"22","publisher":"Springer Nature","article_type":"original","keyword":["General Physics and Astronomy"],"language":[{"iso":"eng"}],"year":"2023","arxiv":1,"publication_identifier":{"issn":["2399-3650"]},"corr_author":"1","abstract":[{"lang":"eng","text":"The model of a ring threaded by the Aharonov-Bohm flux underlies our understanding of a coupling between gauge potentials and matter. The typical formulation of the model is based upon a single particle picture, and should be extended when interactions with other particles become relevant. Here, we illustrate such an extension for a particle in an Aharonov-Bohm ring subject to interactions with a weakly interacting Bose gas. We show that the ground state of the system can be described using the Bose-polaron concept—a particle dressed by interactions with a bosonic environment. We connect the energy spectrum to the effective mass of the polaron, and demonstrate how to change currents in the system by tuning boson-particle interactions. Our results suggest the Aharonov-Bohm ring as a platform for studying coherence and few- to many-body crossover of quasi-particles that arise from an impurity immersed in a medium."}],"quality_controlled":"1","isi":1,"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":["2301.10488"],"isi":["001052577500002"]},"date_published":"2023-08-22T00:00:00Z","date_updated":"2024-10-09T21:06:47Z","publication_status":"published","title":"Emergence of a Bose polaron in a small ring threaded by the Aharonov-Bohm flux","type":"journal_article","acknowledgement":"Open Access funding enabled and organized by Projekt DEAL.\r\nWe would like to thank Jonas Jager for sharing his data with us in the early stages of this project.

Concentration of intracellular signaling machinery near ER-PM junctions allows these domains to serve critical roles in lipid and Ca2+ signaling and homeostasis. Subcellular compartmentalization of protein kinase A (PKA) signaling also regulates essential cellular functions, however, no specific association between PKA and ER-PM junctional domains is known. Here, we show that in brain neurons type I PKA is directed to Kv2.1 channel-dependent ER-PM junctional domains via SPHKAP, a type I PKA-specific anchoring protein. SPHKAP association with type I PKA regulatory subunit RI and ER-resident VAP proteins results in the concentration of type I PKA between stacked ER cisternae associated with ER-PM junctions. This ER-associated PKA signalosome enables reciprocal regulation between PKA and Ca2+ signaling machinery to support Ca2+ influx and excitation-transcription coupling. These data reveal that neuronal ER-PM junctions support a receptor-independent form of PKA signaling driven by membrane depolarization and intracellular Ca2+, allowing conversion of information encoded in electrical signals into biochemical changes universally recognized throughout the cell."}],"publication_identifier":{"eissn":["2041-1723"]},"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","citation":{"apa":"Vierra, N.

However, early virus-host cell interactions and entry mechanisms remain poorly characterized. Investigating iPSC-derived human neurons and cell lines, we found that virus binding to the cell surface was specific, and 50% of bound virions were endocytosed within 10 min. Virions entered Rab5a+ early endosomes and, subsequently, Rab7a+ and LAMP-1+ late endosomal compartments. Penetration required intact late endosomes and occurred within 30 min following internalization. Virus entry relied on vacuolar acidification, with an optimal pH for viral membrane fusion at pH 5.5. The pH threshold increased to 5.8 with longer pre-exposure of virions to the slightly acidic pH in early endosomes. Strikingly, the particles remained infectious after entering late endosomes with a pH below the fusion threshold. Overall, our study establishes Toscana virus as a late-penetrating virus and reveals an atypical use of vacuolar acidity by this virus to enter host cells."}],"quality_controlled":"1","publication_identifier":{"eissn":["1553-7374"],"issn":["1553-7366"]},"pmid":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ieee":"J.

Space asteroseismology is revolutionizing our knowledge of the internal structure and dynamics of stars. A breakthrough is ongoing with the recent discoveries of signatures of strong magnetic fields in the core of red giant stars. The key signature for such a detection is the asymmetry these fields induce in the frequency splittings of observed dipolar mixed gravito-acoustic modes.\r\nAims. We investigate the ability of the observed asymmetries of the frequency splittings of dipolar mixed modes to constrain the geometrical properties of deep magnetic fields.\r\nMethods. We used the powerful analytical Racah-Wigner algebra used in quantum mechanics to characterize the geometrical couplings of dipolar mixed oscillation modes with various realistically plausible topologies of fossil magnetic fields. We also computed the induced perturbation of their frequencies.\r\nResults. First, in the case of an oblique magnetic dipole, we provide the exact analytical expression of the asymmetry as a function of the angle between the rotation and magnetic axes. Its value provides a direct measure of this angle. Second, considering a combination of axisymmetric dipolar and quadrupolar fields, we show how the asymmetry is blind to the unraveling of the relative strength and sign of each component. Finally, in the case of a given multipole, we show that a negative asymmetry is a signature of non-axisymmetric topologies.\r\nConclusions. Asymmetries of dipolar mixed modes provide a key bit of information on the geometrical topology of deep fossil magnetic fields, but this is insufficient on its own. Asteroseismic constraints should therefore be combined with spectropolarimetric observations and numerical simulations, which aim to predict the more probable stable large-scale geometries."}],"isi":1,"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"},"date_published":"2023-08-01T00:00:00Z","external_id":{"arxiv":["2306.11587"],"isi":["001046037700007"]},"title":"Asymmetries of frequency splittings of dipolar mixed modes: A window on the topology of deep magnetic fields","publication_status":"published","date_updated":"2023-09-06T11:05:58Z"},{"quality_controlled":"1","abstract":[{"lang":"eng","text":"There is currently little evidence that the genetic basis of human phenotype varies significantly across the lifespan. However, time-to-event phenotypes are understudied and can be thought of as reflecting an underlying hazard, which is unlikely to be constant through life when values take a broad range. Here, we find that 74% of 245 genome-wide significant genetic associations with age at natural menopause (ANM) in the UK Biobank show a form of age-specific effect. Nineteen of these replicated discoveries are identified only by our modeling framework, which determines the time dependency of DNA-variant age-at-onset associations without a significant multiple-testing burden. Across the range of early to late menopause, we find evidence for significantly different underlying biological pathways, changes in the signs of genetic correlations of ANM to health indicators and outcomes, and differences in inferred causal relationships. We find that DNA damage response processes only act to shape ovarian reserve and depletion for women of early ANM. Genetically mediated delays in ANM were associated with increased relative risk of breast cancer and leiomyoma at all ages and with high cholesterol and heart failure for late-ANM women. These findings suggest that a better understanding of the age dependency of genetic risk factor relationships among health indicators and outcomes is achievable through appropriate statistical modeling of large-scale biobank data."}],"date_published":"2023-09-07T00:00:00Z","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":["37543033"],"isi":["001074842500001"]},"isi":1,"date_updated":"2025-09-09T12:51:20Z","title":"Genetic insights into the age-specific biological mechanisms governing human ovarian aging","publication_status":"published","publication_identifier":{"eissn":["1537-6605"],"issn":["0002-9297"]},"corr_author":"1","publication":"American Journal of Human Genetics","pmid":1,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","citation":{"mla":"Ojavee, Sven E., et al. “Genetic Insights into the Age-Specific Biological Mechanisms Governing Human Ovarian Aging.” <i>American Journal of Human Genetics</i>, vol. 110, no. 9, Elsevier, 2023, pp. 1549–63, doi:<a href=\"https://doi.org/10.1016/j.ajhg.2023.07.006\">10.1016/j.ajhg.2023.07.006</a>.","ista":"Ojavee SE, Darrous L, Patxot M, Läll K, Fischer K, Mägi R, Kutalik Z, Robinson MR. 2023.
