However, the monomeric PSI structure has not yet been reported despite long-standing interest in its structure and extensive spectroscopic characterization of the loss of red chlorophylls upon monomerization. Here, we describe the structure of monomeric PSI from Thermosynechococcus elongatus BP-1. Comparison with the trimer structure gave detailed insights into monomerization-induced changes in both the central trimerization domain and the peripheral regions of the complex. Monomerization-induced loss of red chlorophylls is assigned to a cluster of chlorophylls adjacent to PsaX. Based on our findings, we propose a role of PsaX in the stabilization of red chlorophylls and that lipids of the surrounding membrane present a major source of thermal energy for uphill excitation energy transfer from red chlorophylls to P700.","lang":"eng"}],"file_date_updated":"2021-11-19T15:09:18Z","type":"journal_article","citation":{"ieee":"M.

Many Enterobacteriaceae express type 1 pili, a pre-adapted virulence trait, to invade host epithelial cells and establish persistent infections. However, the molecular mechanisms and strategies by which bacteria actively circumvent the immune response of the host remain poorly understood. Here, we identified CD14, the major co-receptor for lipopolysaccharide detection, on dendritic cells as a previously undescribed binding partner of FimH, the protein located at the tip of the type 1 pilus of Escherichia coli. The FimH amino acids involved in CD14 binding are highly conserved across pathogenic and non-pathogenic strains. Binding of pathogenic bacteria to CD14 lead to reduced dendritic cell migration and blunted expression of co-stimulatory molecules, both rate-limiting factors of T cell activation. While defining an active molecular mechanism of immune evasion by pathogens, the interaction between FimH and CD14 represents a potential target to interfere with persistent and recurrent infections, such as urinary tract infections or Crohn’s disease.","lang":"eng"}],"type":"preprint","citation":{"apa":"Tomasek, K., Leithner, A.

We have discovered that, in Caenorhabditis elegans, neuronal heat shock factor 1 (HSF-1), the conserved master regulator of the heat shock response (HSR), causes extensive fat remodeling in peripheral tissues. These changes include a decrease in fat desaturase and acid lipase expression in the intestine and a global shift in the saturation levels of plasma membrane’s phospholipids. The observed remodeling of plasma membrane is in line with ectothermic adaptive responses and gives worms a cumulative advantage to warm temperatures. We have determined that at least 6 TAX-2/TAX-4 cyclic guanosine monophosphate (cGMP) gated channel expressing sensory neurons, and transforming growth factor ß (TGF-β)/bone morphogenetic protein (BMP) are required for signaling across tissues to modulate fat desaturation. We also find neuronal hsf-1 is not only sufficient but also partially necessary to control the fat remodeling response and for survival at warm temperatures. This is the first study to show that a thermostat-based mechanism can cell nonautonomously coordinate membrane saturation and composition across tissues in a multicellular animal.","lang":"eng"}],"type":"journal_article","file_date_updated":"2021-11-22T09:34:03Z","citation":{"apa":"Chauve, L., Hodge, F., Murdoch, S., Masoudzadeh, F., Mann, H.

Dynamic disorder is a key feature of the complexes of molecular chaperones and their client proteins, and it facilitates the client release towards a folded state or the handover to downstream components. The dynamic nature also implies that a given chaperone can interact with many different client proteins, based on physico-chemical sequence properties rather than on structural complementarity of their (folded) 3D structure. Yet, the balance between this promiscuity and some degree of client specificity is poorly understood. Here, we review recent atomic-level descriptions of chaperones with client proteins, including chaperones in complex with intrinsically disordered proteins, with membrane-protein precursors, or partially folded client proteins. We focus hereby on chaperone-client interactions that are independent of ATP. The picture emerging from these studies highlights the importance of dynamics in these complexes, whereby several interaction types, not only hydrophobic ones, contribute to the complex formation. We discuss these features of chaperone-client complexes and possible factors that may contribute to this balance of promiscuity and specificity."}],"scopus_import":"1","_id":"10323","quality_controlled":"1"},{"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","author":[{"full_name":"Avarikioti, Zeta","first_name":"Zeta","last_name":"Avarikioti"},{"full_name":"Kokoris Kogias, Eleftherios","last_name":"Kokoris Kogias","id":"f5983044-d7ef-11ea-ac6d-fd1430a26d30","first_name":"Eleftherios"},{"first_name":"Roger","last_name":"Wattenhofer","full_name":"Wattenhofer, Roger"},{"full_name":"Zindros, Dionysis","first_name":"Dionysis","last_name":"Zindros"}],"title":"Brick: Asynchronous incentive-compatible payment channels","publisher":"Springer Nature","language":[{"iso":"eng"}],"department":[{"_id":"ElKo"}],"article_processing_charge":"No","quality_controlled":"1","_id":"10324","scopus_import":"1","abstract":[{"lang":"eng","text":"Off-chain protocols (channels) are a promising solution to the scalability and privacy challenges of blockchain payments. Current proposals, however, require synchrony assumptions to preserve the safety of a channel, leaking to an adversary the exact amount of time needed to control the network for a successful attack. In this paper, we introduce Brick, the first payment channel that remains secure under network asynchrony and concurrently provides correct incentives. The core idea is to incorporate the conflict resolution process within the channel by introducing a rational committee of external parties, called wardens. Hence, if a party wants to close a channel unilaterally, it can only get the committee’s approval for the last valid state. Additionally, Brick provides sub-second latency because it does not employ heavy-weight consensus. Instead, Brick uses consistent broadcast to announce updates and close the channel, a light-weight abstraction that is powerful enough to preserve safety and liveness to any rational parties. We formally define and prove for Brick the properties a payment channel construction should fulfill. We also design incentives for Brick such that honest and rational behavior aligns. Finally, we provide a reference implementation of the smart contracts in Solidity."}],"arxiv":1,"type":"conference","citation":{"apa":"Avarikioti, Z., Kokoris Kogias, E., Wattenhofer, R., &#38; Zindros, D.

While by design, blockchains provide no means to securely communicate with external systems, numerous attempts towards trustless cross-chain communication have been proposed over the years. Today, cross-chain communication (CCC) plays a fundamental role in cryptocurrency exchanges, scalability efforts via sharding, extension of existing systems through sidechains, and bootstrapping of new blockchains. Unfortunately, existing proposals are designed ad-hoc for specific use-cases, making it hard to gain confidence in their correctness and composability. We provide the first systematic exposition of cross-chain communication protocols. We formalize the underlying research problem and show that CCC is impossible without a trusted third party, contrary to common beliefs in the blockchain community. With this result in mind, we develop a framework to design new and evaluate existing CCC protocols, focusing on the inherent trust assumptions thereof, and derive a classification covering the field of cross-chain communication to date. We conclude by discussing open challenges for CCC research and the implications of interoperability on the security and privacy of blockchains.","lang":"eng"}],"type":"conference","_id":"10325","quality_controlled":"1","article_processing_charge":"No","department":[{"_id":"ElKo"}],"language":[{"iso":"eng"}],"publisher":"Springer Nature","title":"SoK: Communication across distributed ledgers","author":[{"first_name":"Alexei","last_name":"Zamyatin","full_name":"Zamyatin, Alexei"},{"full_name":"Al-Bassam, Mustafa","last_name":"Al-Bassam","first_name":"Mustafa"},{"full_name":"Zindros, Dionysis","last_name":"Zindros","first_name":"Dionysis"},{"first_name":"Eleftherios","id":"f5983044-d7ef-11ea-ac6d-fd1430a26d30","last_name":"Kokoris Kogias","full_name":"Kokoris Kogias, Eleftherios"},{"full_name":"Moreno-Sanchez, Pedro","first_name":"Pedro","last_name":"Moreno-Sanchez"},{"first_name":"Aggelos","last_name":"Kiayias","full_name":"Kiayias, Aggelos"},{"full_name":"Knottenbelt, William J.","first_name":"William J.","last_name":"Knottenbelt"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","publication":"25th International Conference on Financial Cryptography and Data Security","doi":"10.1007/978-3-662-64331-0_1","main_file_link":[{"url":"https://eprint.iacr.org/2019/1128","open_access":"1"}],"oa_version":"Preprint","isi":1,"volume":"12675 ","date_created":"2021-11-21T23:01:29Z","status":"public","day":"23","page":"3-36","external_id":{"isi":["000712016200001"]},"conference":{"location":"Virtual","name":"FC: Financial Cryptography","end_date":"2021-03-05","start_date":"2021-03-01"},"year":"2021","alternative_title":["LNCS"],"date_published":"2021-10-23T00:00:00Z","month":"10","acknowledgement":"We would like express our gratitude to Georgia Avarikioti, Daniel Perez and Dominik Harz for helpful comments and feedback on earlier versions of this manuscript.

Extensive studies have identified the key components participating in SL biosynthesis and signalling, whereas the catabolism or deactivation of endogenous SLs in planta remains largely unknown. Here, we report that the Arabidopsis carboxylesterase 15 (AtCXE15) and its orthologues function as efficient hydrolases of SLs. We show that overexpression of AtCXE15 promotes shoot branching by dampening SL-inhibited axillary bud outgrowth. We further demonstrate that AtCXE15 could bind and efficiently hydrolyse SLs both in vitro and in planta. We also provide evidence that AtCXE15 is capable of catalysing hydrolysis of diverse SL analogues and that such CXE15-dependent catabolism of SLs is evolutionarily conserved in seed plants. These results disclose a catalytic mechanism underlying homoeostatic regulation of SLs in plants, which also provides a rational approach to spatial-temporally manipulate the endogenous SLs and thus architecture of crops and ornamental plants.","lang":"eng"}],"publication_identifier":{"eissn":["2055-0278"]},"citation":{"chicago":"Xu, Enjun, Liang Chai, Shiqi Zhang, Ruixue Yu, Xixi Zhang, Chongyi Xu, and Yuxin Hu. “Catabolism of Strigolactones by a Carboxylesterase.” <i>Nature Plants</i>.

Here, semiconductor–metal composites are produced by just blending nanoparticles of a sulfide semiconductor obtained in aqueous solution and at room temperature with a metallic Cu powder. The obtained blend is annealed in a reducing atmosphere and afterward consolidated into dense polycrystalline pellets through spark plasma sintering (SPS). We observe that, during the annealing process, the presence of metallic copper activates a partial reduction of the PbS, resulting in the formation of PbS–Pb–CuxS composites. The presence of metallic lead during the SPS process habilitates the liquid-phase sintering of the composite. Besides, by comparing the transport properties of PbS, the PbS–Pb–CuxS composites, and PbS–CuxS composites obtained by blending PbS and CuxS nanoparticles, we demonstrate that the presence of metallic lead decisively contributes to a strong increase of the charge carrier concentration through spillover of charge carriers enabled by the low work function of lead. The increase in charge carrier concentration translates into much higher electrical conductivities and moderately lower Seebeck coefficients. These properties translate into power factors up to 2.1 mW m–1 K–2 at ambient temperature, well above those of PbS and PbS + CuxS. Additionally, the presence of multiple phases in the final composite results in a notable decrease in the lattice thermal conductivity. Overall, the introduction of metallic copper in the initial blend results in a significant improvement of the thermoelectric performance of PbS, reaching a dimensionless thermoelectric figure of merit ZT = 1.1 at 750 K, which represents about a 400% increase over bare PbS. Besides, an average ZTave = 0.72 in the temperature range 320–773 K is demonstrated.","lang":"eng"}],"type":"journal_article","citation":{"ama":"Li M, Liu Y, Zhang Y, et al.

We constructed a fusion protein that stimulates red blood cell production and neuroprotection without triggering platelet production, a marker for thrombosis. The protein consists of an anti-glycophorin A nanobody and an erythropoietin mutant (L108A). The mutation reduces activation of erythropoietin receptor homodimers that induce erythropoiesis and thrombosis, but maintains the tissue-protective signaling. The binding of the nanobody element to glycophorin A rescues homodimeric erythropoietin receptor activation on red blood cell precursors. In a cell proliferation assay, the fusion protein is active at 10−14 M, allowing an estimate of the number of receptor–ligand complexes needed for signaling. This fusion protein stimulates erythroid cell proliferation in vitro and in mice, and shows neuroprotective activity in vitro.

Here we study epithelial cell monolayers on corrugated hydrogels engineered into wavy patterns, examining how concave and convex curvatures affect cellular and nuclear shape. We find that substrate curvature affects monolayer thickness, which is larger in valleys than crests. We show that this feature generically arises in a vertex model, leading to the hypothesis that cells may sense curvature by modifying the thickness of the tissue. We find that local curvature also affects nuclear morphology and positioning, which we explain by extending the vertex model to take into account membrane–nucleus interactions, encoding thickness modulation in changes to nuclear deformation and position. We propose that curvature governs the spatial distribution of yes-associated proteins via nuclear shape and density changes. We show that curvature also induces significant variations in lamins, chromatin condensation and cell proliferation rate in folded epithelial tissues. Together, this work identifies active cell mechanics and nuclear mechanoadaptation as the key players of the mechanistic regulation of epithelia to substrate curvature.","lang":"eng"}],"scopus_import":"1","file_date_updated":"2023-10-11T09:31:43Z","type":"journal_article","citation":{"mla":"Luciano, Marine, et al. “Cell Monolayers Sense Curvature by Exploiting Active Mechanics and Nuclear Mechanoadaptation.” <i>Nature Physics</i>, vol. 17, no. 12, Springer Nature, 2021, pp. 1382–1390, doi:<a href=\"https://doi.org/10.1038/s41567-021-01374-1\">10.1038/s41567-021-01374-1</a>.","apa":"Luciano, M., Xue, S., De Vos, W.

With ever-larger amounts of unstructured and limited labels, organizing and reconciling information from different sources and modalities is a central challenge in machine learning. This cutting-edge tutorial aims to introduce the multimodal entailment task, which can be useful for detecting semantic alignments when a single modality alone does not suffice for a whole content understanding. Starting with a brief overview of natural language processing, computer vision, structured data and neural graph learning, we lay the foundations for the multimodal sections to follow. We then discuss recent multimodal learning literature covering visual, audio and language streams, and explore case studies focusing on tasks which require fine-grained understanding of visual and linguistic semantics question answering, veracity and hatred classification. Finally, we introduce a new dataset for recognizing multimodal entailment, exploring it in a hands-on collaborative section. Overall, this tutorial gives an overview of multimodal learning, introduces a multimodal entailment dataset, and encourages future research in the topic."}],"file_date_updated":"2021-11-29T08:41:00Z","type":"conference","_id":"10367","quality_controlled":"1","article_processing_charge":"No","department":[{"_id":"HeEd"}],"language":[{"iso":"eng"}],"has_accepted_license":"1","publisher":"Association for Computational Linguistics","title":"Recognizing multimodal entailment","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","author":[{"full_name":"Ilharco, Cesar","last_name":"Ilharco","first_name":"Cesar"},{"last_name":"Shirazi","first_name":"Afsaneh","full_name":"Shirazi, Afsaneh"},{"full_name":"Gopalan, Arjun","last_name":"Gopalan","first_name":"Arjun"},{"full_name":"Nagrani, Arsha","first_name":"Arsha","last_name":"Nagrani"},{"full_name":"Bratanič, Blaž","last_name":"Bratanič","first_name":"Blaž"},{"full_name":"Bregler, Chris","first_name":"Chris","last_name":"Bregler"},{"full_name":"Liu, Christina","last_name":"Liu","first_name":"Christina"},{"last_name":"Ferreira","first_name":"Felipe","full_name":"Ferreira, Felipe"},{"full_name":"Barcik, Gabriek","first_name":"Gabriek","last_name":"Barcik"},{"last_name":"Ilharco","first_name":"Gabriel","full_name":"Ilharco, Gabriel"},{"last_name":"Osang","first_name":"Georg F","id":"464B40D6-F248-11E8-B48F-1D18A9856A87","full_name":"Osang, Georg F"},{"full_name":"Bulian, Jannis","last_name":"Bulian","first_name":"Jannis"},{"full_name":"Frank, Jared","last_name":"Frank","first_name":"Jared"},{"full_name":"Smaira, Lucas","last_name":"Smaira","first_name":"Lucas"},{"first_name":"Qin","last_name":"Cao","full_name":"Cao, Qin"},{"full_name":"Marino, Ricardo","last_name":"Marino","first_name":"Ricardo"},{"last_name":"Patel","first_name":"Roma","full_name":"Patel, Roma"},{"full_name":"Leung, Thomas","last_name":"Leung","first_name":"Thomas"},{"full_name":"Imbrasaite, Vaiva","first_name":"Vaiva","last_name":"Imbrasaite"}],"file":[{"date_created":"2021-11-29T08:41:00Z","date_updated":"2021-11-29T08:41:00Z","success":1,"file_name":"2021_ACL_Ilharco.pdf","relation":"main_file","access_level":"open_access","checksum":"b14052a025a6ecf675bdfe51db98c0d7","file_id":"10368","content_type":"application/pdf","file_size":1227703,"creator":"cchlebak"}]},{"volume":4,"tmp":{"image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"date_created":"2021-12-05T23:01:39Z","ddc":["530"],"day":"26","status":"public","publication":"Communications Physics","doi":"10.1038/s42005-021-00753-7","ec_funded":1,"oa_version":"Published Version","date_published":"2021-11-26T00:00:00Z","intvolume":"         4","month":"11","article_number":"252","acknowledgement":"The authors acknowledge support from the European QuantERA ERA-NET Cofund in Quantum Technologies (Project QTFLAG Grant Agreement No. 731473) (R.E.B), CNPq (Conselho Nacional de Desenvolvimento Científico e Tecnológico) Brazil (A.F.), the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie Grant Agreement No. 754411 (A.G.V.), the Independent Research Fund Denmark, the Carlsberg Foundation, and Aarhus University Research Foundation under the Jens Christian Skou fellowship program (N.T.Z).","date_updated":"2023-08-14T13:04:34Z","oa":1,"issue":"1","external_id":{"isi":["10.1038/s42005-021-00753-7"],"arxiv":["2101.02020"]},"year":"2021","citation":{"short":"R.E.

In this work, we propose a two-terminal cold-atom simulator to study that interaction. The proposed quantum simulator consists of strongly interacting atoms that occupy two temperature reservoirs connected by a one-dimensional link. First, we argue that the dynamics in the link can be described using an inhomogeneous Heisenberg spin chain whose couplings are defined by the local temperature. Second, we show the existence of a spin current in a system with a temperature difference by studying the dynamics that follows the spin-flip of an atom in the link. A temperature gradient accelerates the impurity in one direction more than in the other, leading to an overall spin current similar to the spin Seebeck effect.","lang":"eng"}],"arxiv":1,"scopus_import":"1","type":"journal_article","file_date_updated":"2021-12-06T14:53:41Z","_id":"10401","quality_controlled":"1","project":[{"name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"754411"}],"publication_status":"published","has_accepted_license":"1","publisher":"Springer Nature","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","title":"Generation of spin currents by a temperature gradient in a two-terminal device","author":[{"first_name":"Rafael E.","last_name":"Barfknecht","full_name":"Barfknecht, Rafael E."},{"first_name":"Angela","last_name":"Foerster","full_name":"Foerster, Angela"},{"first_name":"Nikolaj T.","last_name":"Zinner","full_name":"Zinner, Nikolaj T."},{"full_name":"Volosniev, Artem","last_name":"Volosniev","orcid":"0000-0003-0393-5525","first_name":"Artem","id":"37D278BC-F248-11E8-B48F-1D18A9856A87"}],"file":[{"creator":"alisjak","file_size":1068984,"file_id":"10420","content_type":"application/pdf","relation":"main_file","checksum":"9097319952cb9a3d96e7fd3aa9813a03","access_level":"open_access","file_name":"2021_NatComm_Barfknecht.pdf","success":1,"date_updated":"2021-12-06T14:53:41Z","date_created":"2021-12-06T14:53:41Z"}],"article_processing_charge":"No","department":[{"_id":"MiLe"}],"language":[{"iso":"eng"}],"article_type":"original"},{"pmid":1,"volume":12,"tmp":{"image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"ddc":["573"],"date_created":"2021-12-05T23:01:40Z","day":"24","status":"public","doi":"10.1038/s41467-021-27135-5","publication":"Nature Communications","related_material":{"record":[{"relation":"research_data","status":"public","id":"13058"}]},"isi":1,"ec_funded":1,"oa_version":"Published Version","intvolume":"        12","month":"11","date_published":"2021-11-24T00:00:00Z","acknowledgement":"We thank all members of our respective groups for helpful discussion on the paper.

Many studies have explored system-specific molecular and cellular regulatory mechanisms, as well as self-organizing rules underlying branching morphogenesis. However, in addition to local cues, branched tissue growth can also be influenced by global guidance. Here, we develop a theoretical framework for a stochastic self-organized branching process in the presence of external cues. Combining analytical theory with numerical simulations, we predict differential signatures of global vs. local regulatory mechanisms on the branching pattern, such as angle distributions, domain size, and space-filling efficiency. We find that branch alignment follows a generic scaling law determined by the strength of global guidance, while local interactions influence the tissue density but not its overall territory. Finally, using zebrafish innervation as a model system, we test these key features of the model experimentally. Our work thus provides quantitative predictions to disentangle the role of different types of cues in shaping branched structures across scales."}],"_id":"10402","quality_controlled":"1","project":[{"name":"Design Principles of Branching Morphogenesis","_id":"05943252-7A3F-11EA-A408-12923DDC885E","grant_number":"851288","call_identifier":"H2020"},{"call_identifier":"H2020","grant_number":"754411","name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425"}],"publication_status":"published","has_accepted_license":"1","publisher":"Springer Nature","file":[{"file_name":"2021_NatComm_Ucar.pdf","success":1,"date_updated":"2021-12-10T08:54:09Z","date_created":"2021-12-10T08:54:09Z","creator":"cchlebak","file_size":2303405,"file_id":"10529","content_type":"application/pdf","relation":"main_file","checksum":"63c56ec75314a71e63e7dd2920b3c5b5","access_level":"open_access"}],"author":[{"full_name":"Ucar, Mehmet C","first_name":"Mehmet C","id":"50B2A802-6007-11E9-A42B-EB23E6697425","last_name":"Ucar","orcid":"0000-0003-0506-4217"},{"last_name":"Kamenev","first_name":"Dmitrii","full_name":"Kamenev, Dmitrii"},{"full_name":"Sunadome, Kazunori","last_name":"Sunadome","first_name":"Kazunori"},{"full_name":"Fachet, Dominik C","last_name":"Fachet","id":"14FDD550-AA41-11E9-A0E5-1ACCE5697425","first_name":"Dominik C"},{"full_name":"Lallemend, Francois","first_name":"Francois","last_name":"Lallemend"},{"full_name":"Adameyko, Igor","first_name":"Igor","last_name":"Adameyko"},{"first_name":"Saida","last_name":"Hadjab","full_name":"Hadjab, Saida"},{"id":"3A9DB764-F248-11E8-B48F-1D18A9856A87","first_name":"Edouard B","last_name":"Hannezo","orcid":"0000-0001-6005-1561","full_name":"Hannezo, Edouard B"}],"title":"Theory of branching morphogenesis by local interactions and global guidance","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","article_processing_charge":"No","department":[{"_id":"EdHa"}],"language":[{"iso":"eng"}],"article_type":"original"},{"file":[{"date_created":"2021-12-10T08:31:41Z","date_updated":"2021-12-10T08:31:41Z","success":1,"file_name":"2021_eLife_Biane.pdf","relation":"main_file","checksum":"c7c33c3319428d56e332e22349c50ed3","access_level":"open_access","content_type":"application/pdf","file_id":"10528","file_size":13131322,"creator":"cchlebak"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","title":"Developmental emergence of two-stage nonlinear synaptic integration in cerebellar interneurons","author":[{"full_name":"Biane, Celia","first_name":"Celia","last_name":"Biane"},{"first_name":"Florian","last_name":"Rückerl","full_name":"Rückerl, Florian"},{"full_name":"Abrahamsson, Therese","last_name":"Abrahamsson","first_name":"Therese"},{"first_name":"Cécile","last_name":"Saint-Cloment","full_name":"Saint-Cloment, Cécile"},{"full_name":"Mariani, Jean","last_name":"Mariani","first_name":"Jean"},{"full_name":"Shigemoto, Ryuichi","last_name":"Shigemoto","orcid":"0000-0001-8761-9444","first_name":"Ryuichi","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Digregorio, David A.","first_name":"David A.","last_name":"Digregorio"},{"full_name":"Sherrard, Rachel M.","first_name":"Rachel M.","last_name":"Sherrard"},{"first_name":"Laurence","last_name":"Cathala","full_name":"Cathala, Laurence"}],"has_accepted_license":"1","publisher":"eLife Sciences Publications","language":[{"iso":"eng"}],"article_type":"original","article_processing_charge":"No","department":[{"_id":"RySh"}],"_id":"10403","quality_controlled":"1","citation":{"chicago":"Biane, Celia, Florian Rückerl, Therese Abrahamsson, Cécile Saint-Cloment, Jean Mariani, Ryuichi Shigemoto, David A.

Yet how these changes influence the neuronal computations necessary for normal brain function are not well understood. To identify cellular mechanisms underlying the maturation of synaptic integration in interneurons, we combined patch-clamp recordings of excitatory inputs in mouse cerebellar stellate cells (SCs), three-dimensional reconstruction of SC morphology with excitatory synapse location, and biophysical modeling. We found that postnatal maturation of postsynaptic strength was homogeneously reduced along the somatodendritic axis, but dendritic integration was always sublinear. However, dendritic branching increased without changes in synapse density, leading to a substantial gain in distal inputs. Thus, changes in synapse distribution, rather than dendrite cable properties, are the dominant mechanism underlying the maturation of neuronal computation. These mechanisms favor the emergence of a spatially compartmentalized two-stage integration model promoting location-dependent integration within dendritic subunits."}],"publication_status":"published","date_updated":"2023-08-14T13:12:07Z","oa":1,"intvolume":"        10","month":"11","date_published":"2021-11-03T00:00:00Z","article_number":"e65954","acknowledgement":"This study was supported by the Centre National de la Recherche Scientifique and the Agence Nationale de la Recherche (ANR-13-BSV4-00166, to LC and DAD).

Perturber offers a large variety of scene modifications, such as camera controls, lighting and shading effects, background modifications, object morphing, as well as adversarial attacks, to facilitate the discovery of potential vulnerabilities. Fine-tuned model versions can be directly compared for qualitative evaluation of their robustness. Case studies with machine learning experts have shown that Perturber helps users to quickly generate hypotheses about model vulnerabilities and to qualitatively compare model behavior.

Morphogenesis involves an interplay between several factors, ranging from the gene regulatory networks determining cell fate and differentiation to the mechanical processes underlying cell and tissue shape changes. Thus, the study of morphogenesis has historically been based on multidisciplinary approaches at the interface of biology with physics and mathematics. Recent technological advances have further improved our ability to study morphogenesis by bridging the gap between the genetic and biophysical factors through the development of new tools for visualizing, analyzing, and perturbing these factors and their biochemical intermediaries.

For example, the circuit can differ from its specified input/output behavior after some fixed number of queries (known as “time bombs”) or on some particular input (known as “cheat codes”). To detect such Trojans, countermeasures using multiparty computation (MPC) or verifiable computation (VC) have been proposed. On a high level, to realize a circuit with specification   F  one has more sophisticated circuits   F⋄  manufactured (where   F⋄  specifies a MPC or VC of   F ), and then embeds these   F⋄ ’s into a master circuit which must be trusted but is relatively simple compared to   F . Those solutions impose a significant overhead as   F⋄  is much more complex than   F , also the master circuits are not exactly trivial. In this work, we show that in restricted settings, where   F  has no evolving state and is queried on independent inputs, we can achieve a relaxed security notion using very simple constructions. In particular, we do not change the specification of the circuit at all (i.e.,   F=F⋄ ). Moreover the master circuit basically just queries a subset of its manufactured circuits and checks if they’re all the same. The security we achieve guarantees that, if the manufactured circuits are initially tested on up to T inputs, the master circuit will catch Trojans that try to deviate on significantly more than a 1/T fraction of the inputs. This bound is optimal for the type of construction considered, and we provably achieve it using a construction where 12 instantiations of   F  need to be embedded into the master. We also discuss an extremely simple construction with just 2 instantiations for which we conjecture that it already achieves the optimal bound."}],"scopus_import":"1","publication_identifier":{"isbn":["9-783-0309-0452-4"],"eissn":["1611-3349"],"issn":["0302-9743"]},"citation":{"mla":"Chakraborty, Suvradip, et al. <i>Trojan-Resilience without Cryptography</i>.

Applications include multicast encryption protocols like LKH (Logical Key Hierarchies) or group messaging like the current IETF proposal TreeKEM. A key tree is a (typically balanced) binary tree, where each node is identified with a key: leaf nodes hold users’ secret keys while the root is the shared group key. For a group of size N, each user just holds   log(N)  keys (the keys on the path from its leaf to the root) and its entire key material can be rotated by broadcasting   2log(N)  ciphertexts (encrypting each fresh key on the path under the keys of its parents). In this work we consider the natural setting where we have many groups with partially overlapping sets of users, and ask if we can find solutions where the cost of rotating a key is better than in the trivial one where we have a separate key tree for each group. We show that in an asymptotic setting (where the number m of groups is fixed while the number N of users grows) there exist more general key graphs whose cost converges to the cost of a single group, thus saving a factor linear in the number of groups over the trivial solution. As our asymptotic “solution” converges very slowly and performs poorly on concrete examples, we propose an algorithm that uses a natural heuristic to compute a key graph for any given group structure. Our algorithm combines two greedy algorithms, and is thus very efficient: it first converts the group structure into a “lattice graph”, which is then turned into a key graph by repeatedly applying the algorithm for constructing a Huffman code. To better understand how far our proposal is from an optimal solution, we prove lower bounds on the update cost of continuous group-key agreement and multicast encryption in a symbolic model admitting (asymmetric) encryption, pseudorandom generators, and secret sharing as building blocks."}],"scopus_import":"1","publication_identifier":{"issn":["0302-9743"],"isbn":["9-783-0309-0455-5"],"eissn":["1611-3349"],"eisbn":["978-3-030-90456-2"]},"citation":{"ista":"Alwen JF, Auerbach B, Baig MA, Cueto Noval M, Klein K, Pascual Perez G, Pietrzak KZ, Walter M. 2021.
