By studying a pair of structurally homologous cross-β amyloid fibrils, HET-s and HELLF, with a specific isotope-labeling approach and magic-angle-spinning (MAS) NMR, we have characterized the dynamic behavior of Phe and Tyr aromatic rings to show that the hydrophobic amyloid core is rigid, without any sign of \"breathing motions\" over hundreds of milliseconds at least. Aromatic residues exposed at the fibril surface have a rigid ring axis but undergo ring flips, on a variety of time scales from ns to µs. Our approach provides direct insight into hydrophobic-core motions, enabling a better evaluation of the conformational heterogeneity generated from a NMR structural ensemble of such amyloid cross-β architecture.","lang":"eng"}],"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc/4.0/legalcode","image":"/images/cc_by_nc.png","name":"Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)","short":"CC BY-NC (4.0)"},"publication_status":"published","_id":"12675","publication":"Angewandte Chemie International Edition","corr_author":"1","acknowledgement":"We thank AlbertA.

Inherently invisible to crystallography, aromatic motions have been primarily studied by solution NMR. The question how packing of proteins in crystals affects ring flips has, thus, remained largely unexplored. Here we apply magic-angle spinning NMR, advanced phenylalanine 1H-13C/2H isotope labeling and MD simulation to a protein in three different crystal packing environments to shed light onto possible impact of packing on ring flips. The flips of the two Phe residues in ubiquitin, both surface exposed, appear remarkably conserved in the different crystal forms, even though the intermolecular packing is quite different: Phe4 flips on a ca. 10–20 ns time scale, and Phe45 are broadened in all crystals, presumably due to µs motion. Our findings suggest that intramolecular influences are more important for ring flips than intermolecular (packing) effects.","lang":"eng"}],"tmp":{"short":"CC BY-NC-ND (4.0)","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","image":"/images/cc_by_nc_nd.png","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode"},"_id":"12114","publication":"Journal of Structural Biology: X","publication_status":"published","publisher":"Elsevier","oa_version":"Published Version","type":"journal_article","year":"2023","day":"01","intvolume":" 7","status":"public","fulldoi":"https://doi.org/10.1016/j.yjsbx.2022.100079","article_number":"100079","has_accepted_license":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","pmid":1},{"file":[{"success":1,"file_id":"13978","content_type":"application/pdf","relation":"main_file","checksum":"fb36dda665e57bab006a000bf0faacd5","date_updated":"2023-08-07T07:48:11Z","creator":"dernst","file_size":2421758,"access_level":"open_access","file_name":"2023_FrontiersPhysics_Hasler.pdf","date_created":"2023-08-07T07:48:11Z"}],"quality_controlled":"1","oa":1,"volume":11,"abstract":[{"text":"The use of multimodal readout mechanisms next to label-free real-time monitoring of biomolecular interactions can provide valuable insight into surface-based reaction mechanisms. To this end, the combination of an electrolyte-gated field-effect transistor (EG-FET) with a fiber optic-coupled surface plasmon resonance (FO-SPR) probe serving as gate electrode has been investigated to deconvolute surface mass and charge density variations associated to surface reactions. However, applying an electrochemical potential on such gold-coated FO-SPR gate electrodes can induce gradual morphological changes of the thin gold film, leading to an irreversible blue-shift of the SPR wavelength and a substantial signal drift. We show that mild annealing leads to optical and electronic signal stabilization (20-fold lower signal drift than as-sputtered fiber optic gates) and improved overall analytical performance characteristics. The thermal treatment prevents morphological changes of the thin gold-film occurring during operation, hence providing reliable and stable data immediately upon gate voltage application. Thus, the readout output of both transducing principles, the optical FO-SPR and electronic EG-FET, stays constant throughout the whole sensing time-window and the long-term effect of thermal treatment is also improved, providing stable signals even after 1 year of storage. Annealing should therefore be considered a necessary modification for applying fiber optic gate electrodes in real-time multimodal investigations of surface reactions at the solid-liquid interface.","lang":"eng"}],"doi":"10.3389/fphy.2023.1202132","publication_status":"published","tmp":{"image":"/images/cc_by.png","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)"},"_id":"13968","publication":"Frontiers in Physics","intvolume":" 11","fulldoi":"https://doi.org/10.3389/fphy.2023.1202132","article_number":"1202132","status":"public","year":"2023","type":"journal_article","publisher":"Frontiers","oa_version":"Published Version","day":"14","isi":1,"has_accepted_license":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","acknowledged_ssus":[{"_id":"EM-Fac"}],"citation":{"ieee":"R.

Yet, several recent works have raised the issue that pruning may induce or exacerbate bias in the output of the compressed model. Despite existing evidence for this phenomenon, the relationship between neural network pruning and induced bias is not well-understood. In this work, we systematically investigate and characterize this phenomenon in Convolutional Neural Networks for computer vision. First, we show that it is in fact possible to obtain highly-sparse models, e.g. with less than 10% remaining weights, which do not decrease in accuracy nor substantially increase in bias when compared to dense models. At the same time, we also find that, at higher sparsities, pruned models exhibit higher uncertainty in their outputs, as well as increased correlations, which we directly link to increased bias. We propose easy-to-use criteria which, based only on the uncompressed model, establish whether bias will increase with pruning, and identify the samples most susceptible to biased predictions post-compression.

Although existing models account for oscillations and avalanches separately, they typically do not explain both phenomena, are too complex to analyze analytically or intractable to infer from data rigorously. Here we propose a feedback-driven Ising-like class of neural networks that captures avalanches and oscillations simultaneously and quantitatively. In the simplest yet fully microscopic model version, we can analytically compute the phase diagram and make direct contact with human brain resting-state activity recordings via tractable inference of the model’s two essential parameters. The inferred model quantitatively captures the dynamics over a broad range of scales, from single sensor oscillations to collective behaviors of extreme events and neuronal avalanches. Importantly, the inferred parameters indicate that the co-existence of scale-specific (oscillations) and scale-free (avalanches) dynamics occurs close to a non-equilibrium critical point at the onset of self-sustained oscillations.","lang":"eng"}],"doi":"10.1038/s43588-023-00410-9","tmp":{"image":"/images/cc_by.png","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)"},"_id":"12762","publication_status":"published","publication":"Nature Computational Science","oa":1,"quality_controlled":"1","file":[{"file_name":"2023_NatureCompScience_Lombardi.pdf","file_size":4474284,"access_level":"open_access","date_created":"2023-08-16T12:39:57Z","content_type":"application/pdf","file_id":"14073","success":1,"creator":"dernst","checksum":"7c63b2b2edfd68aaffe96d70ca6a865a","relation":"main_file","date_updated":"2023-08-16T12:39:57Z"}],"volume":3,"pmid":1,"isi":1,"has_accepted_license":"1","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","intvolume":" 3","status":"public","fulldoi":"https://doi.org/10.1038/s43588-023-00410-9","oa_version":"Published Version","publisher":"Springer Nature","year":"2023","type":"journal_article","ec_funded":1,"day":"20"},{"_id":"13340","publication_status":"published","publication":"Science","doi":"10.1126/science.adh9059","abstract":[{"lang":"eng","text":"Photoisomerization of azobenzenes from their stable E isomer to the metastable Z state is the basis of numerous applications of these molecules. 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."}],"project":[{"_id":"7bef070e-9f16-11ee-852c-db9675e131d9","grant_number":"820008","call_identifier":"H2020","name":"Dissipative self-assembly in synthetic systems: Towards life-like materials"}],"volume":381,"quality_controlled":"1","oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","isi":1,"pmid":1,"day":"22","main_file_link":[{"open_access":"1","url":"https://doi.org/10.26434/chemrxiv-2023-gq2h0"}],"year":"2023","ec_funded":1,"type":"journal_article","oa_version":"Preprint","publisher":"American Association for the Advancement of Science","fulldoi":"https://doi.org/10.1126/science.adh9059","status":"public","OA_type":"green","intvolume":" 381","date_published":"2023-09-22T00:00:00Z","month":"09","chemrxivid":1,"page":"1357-1363","date_updated":"2026-07-29T05:48:56Z","author":[{"last_name":"Gemen","first_name":"Julius","full_name":"Gemen, Julius"},{"full_name":"Church, Jonathan R.","first_name":"Jonathan R.","last_name":"Church"},{"last_name":"Ruoko","full_name":"Ruoko, Tero-Petri","first_name":"Tero-Petri"},{"last_name":"Durandin","full_name":"Durandin, Nikita","first_name":"Nikita"},{"last_name":"Białek","first_name":"Michał J.","full_name":"Białek, Michał J."},{"first_name":"Maren","full_name":"Weissenfels, Maren","last_name":"Weissenfels"},{"last_name":"Feller","full_name":"Feller, Moran","first_name":"Moran"},{"first_name":"Miri","full_name":"Kazes, Miri","last_name":"Kazes"},{"last_name":"Borin","full_name":"Borin, Veniamin A.","first_name":"Veniamin A."},{"first_name":"Magdalena","full_name":"Odaybat, Magdalena","last_name":"Odaybat"},{"last_name":"Kalepu","full_name":"Kalepu, Rishir","first_name":"Rishir"},{"full_name":"Diskin-Posner, Yael","first_name":"Yael","last_name":"Diskin-Posner"},{"last_name":"Oron","first_name":"Dan","full_name":"Oron, Dan"},{"last_name":"Fuchter","first_name":"Matthew J.","full_name":"Fuchter, Matthew J."},{"first_name":"Arri","full_name":"Priimagi, Arri","last_name":"Priimagi"},{"last_name":"Schapiro","full_name":"Schapiro, Igor","first_name":"Igor"},{"first_name":"Rafal","full_name":"Klajn, Rafal","id":"8e84690e-1e48-11ed-a02b-a1e6fb8bb53b","last_name":"Klajn"}],"citation":{"ama":"Gemen J, Church JR, Ruoko T-P, et al.

Mostly building on unsupervised and weakly-supervised objectives, prior work missed out on the positive implications for representation learning on real world data. In this work, we propose to leverage knowledge extracted from a diversified set of supervised tasks to learn a common disentangled representation. Assuming that each supervised task only depends on an unknown subset of the factors of variation, we disentangle the feature space of a supervised multi-task model, with features activating sparsely across different tasks and information being shared as appropriate. Importantly, we never directly observe the factors of variations, but establish that access to multiple tasks is sufficient for identifiability under sufficiency and minimality assumptions. We validate our approach on six real world distribution shift benchmarks, and different data modalities (images, text), demonstrating how disentangled representations can be transferred to real settings."}],"_id":"14210","publication":"37th International Conference on Neural Information Processing Systems","publication_status":"published","intvolume":" 36","article_number":"1204","status":"public","OA_type":"gold","type":"conference","year":"2023","publisher":"Neural Information Processing Systems Foundation","oa_version":"Published Version","day":"10","researchdata_availability":"no","has_accepted_license":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},{"external_id":{"arxiv":["2311.00664"]},"acknowledgement":"This work is supported by the ERC grant no.802554 (SPECGEO), PRIN 2020 project no.2020TA3K9N (LEGO.AI), and PNRR MUR project PE0000013-FAIR.

Recently, the Complex AutoEncoder was proposed as an alternative that learns continuous and distributed object-centric representations. However, it is only applicable to simple toy data. In this paper, we present Rotating Features, a generalization of complex-valued features to higher dimensions, and a new evaluation procedure for extracting objects from distributed representations. Additionally, we show the applicability of our approach to pre-trained features. Together, these advancements enable us to scale distributed object-centric representations from simple toy to real-world data.

Learning grounded representations of objects\r\nthat are guaranteed to be stable and invariant promises robust performance\r\nacross different tasks and environments. Slot Attention (SA) learns\r\nobject-centric representations by assigning objects to \\textit{slots}, but\r\npresupposes a \\textit{single} distribution from which all slots are randomly\r\ninitialised. This results in an inability to learn \\textit{specialized} slots\r\nwhich bind to specific object types and remain invariant to identity-preserving\r\nchanges in object appearance. To address this, we present\r\n\\emph{\\textsc{Co}nditional \\textsc{S}lot \\textsc{A}ttention} (\\textsc{CoSA})\r\nusing a novel concept of \\emph{Grounded Slot Dictionary} (GSD) inspired by\r\nvector quantization. Our proposed GSD comprises (i) canonical object-level\r\nproperty vectors and (ii) parametric Gaussian distributions, which define a\r\nprior over the slots.

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.","lang":"eng"}],"doi":"10.2140/pjm.2023.324.265","volume":324,"file":[{"date_created":"2023-09-05T07:26:17Z","file_name":"2023_PacificJourMaths_Horesh.pdf","file_size":654895,"access_level":"open_access","creator":"dernst","date_updated":"2023-09-05T07:26:17Z","checksum":"a675b53cfb31fa46be1e879b7e77fe8c","relation":"main_file","file_id":"14267","content_type":"application/pdf","success":1}],"quality_controlled":"1","oa":1,"date_created":"2023-08-27T22:01:18Z","language":[{"iso":"eng"}],"publication_identifier":{"issn":["0030-8730"],"eissn":["1945-5844"]},"scopus_import":"1","file_date_updated":"2023-09-05T07:26:17Z","department":[{"_id":"TiBr"}],"article_processing_charge":"Yes","title":"Horospherical coordinates of lattice points in hyperbolic spaces: Effective counting and equidistribution","external_id":{"arxiv":["1612.08215"],"isi":["001047690500001"]},"acknowledgement":"The authors thank the referee for important comments which led to significant improvements is the presentation of several results in the paper.

For any linear algebraic group G over k and any G-torsor g : Z → X, we observe that if the étale-Brauer obstruction is the only one for strong approximation off a finite set of places S for all twists of Z by elements in H^1(k, G), then the étale-Brauer obstruction is the only one for strong approximation off a finite set of places S for X. As an application, we show that any homogeneous space of the form G/H with G a connected linear algebraic group over k satisfies strong approximation off the infinite places with étale-Brauer obstruction, under some compactness assumptions when k is totally real. We also prove more refined strong approximation results for homogeneous spaces of the form G/H with G semisimple simply connected and H finite, using the theory of torsors and descent.","lang":"eng"}],"doi":"10.1090/proc/15239","_id":"12427","publication":"Proceedings of the American Mathematical Society","publication_status":"published","year":"2023","type":"journal_article","oa_version":"Preprint","publisher":"American Mathematical Society","day":"01","researchdata_availability":"no","main_file_link":[{"open_access":"1","url":"https://hal.science/hal-03013498/"}],"intvolume":" 151","fulldoi":"https://doi.org/10.1090/proc/15239","status":"public","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","isi":1},{"volume":24,"quality_controlled":"1","oa":1,"publication_status":"published","_id":"12916","publication":"Annali della Scuola Normale Superiore di Pisa, Classe di Scienze","doi":"10.2422/2036-2145.202010_018","abstract":[{"text":"We apply a variant of the square-sieve to produce an upper bound for the number of rational points of bounded height on a family of surfaces that admit a fibration over P1 whose general fibre is a hyperelliptic curve.
