We present QuePaxa, the first protocol offering state-of-the-art normal-case efficiency without depending on timeouts. QuePaxa uses a novel randomized asynchronous consensus core to tolerate adverse conditions such as denial-of-service (DoS) attacks, while a one-round-trip fast path preserves the normal-case efficiency of Multi-Paxos or Raft. By allowing simultaneous proposers without destructive interference, and using short hedging delays instead of conservative timeouts to limit redundant effort, QuePaxa permits rapid recovery after leader failure without risking costly view changes due to false timeouts. By treating leader choice and hedging delay as a multi-armed-bandit optimization, QuePaxa achieves responsiveness to prevalent conditions, and can choose the best leader even if the current one has not failed. Experiments with a prototype confirm that QuePaxa achieves normal-case LAN and WAN performance of 584k and 250k cmd/sec in throughput, respectively, comparable to Multi-Paxos. Under conditions such as DoS attacks, misconfigurations, or slow leaders that severely impact existing protocols, we find that QuePaxa remains live with median latency under 380ms in WAN experiments."}],"external_id":{"isi":["001135072900018"]},"date_updated":"2026-06-18T17:38:12Z","quality_controlled":"1","publication":"Proceedings of the 29th Symposium on Operating Systems Principles","date_published":"2023-10-01T00:00:00Z","doi":"10.1145/3600006.3613150","fulldoi":"https://doi.org/10.1145/3600006.3613150","scopus_import":"1","article_processing_charge":"No","year":"2023","date_created":"2024-01-08T12:54:35Z","publication_status":"published","type":"conference","main_file_link":[{"url":"https://doi.org/10.1145/3600006.3613150","open_access":"1"}],"conference":{"end_date":"2023-10-26","start_date":"2023-10-23","name":"SOSP: Symposium on Operating Systems Principles","location":"Koblenz, Germany"},"citation":{"chicago":"Tennage, Pasindu, Cristina Basescu, Eleftherios Kokoris Kogias, Ewa Syta, Philipp Jovanovic, Vero Estrada-Galinanes, and Bryan Ford. “QuePaxa: Escaping the Tyranny of Timeouts in Consensus.” In <i>Proceedings of the 29th Symposium on Operating Systems Principles</i>, 281–97.

It is well known that on the macroscopic scale (Invent. Math. 104 (1991) 201–220), the limiting empirical spectral distribution (ESD) of the above model is given by the free multiplicative convolution\r\nof the limiting ESDs of A and B, denoted as μα \u0002 μβ, where μα and μβ are the limiting ESDs of A and B, respectively. In this paper, we study the asymptotic microscopic behavior of the edge eigenvalues and eigenvectors statistics. We prove that both the density of μA \u0002μB, where μA and μB are the ESDs of A and B, respectively and the associated subordination functions\r\nhave a regular behavior near the edges. Moreover, we establish the local laws near the edges on the optimal scale. In particular, we prove that the entries of the resolvent are close to some functionals depending only on the eigenvalues of A, B and the subordination functions with optimal convergence rates. Our proofs and calculations are based on the techniques developed for the additive model A+UBU∗ in (J. Funct. Anal. 271 (2016) 672–719; Comm. Math.\r\nPhys. 349 (2017) 947–990; Adv.

Here we use unprecedented observational constraints from subsidence regimes in the tropical Atlantic to develop a theory for the shape and magnitude of low‐level longwave radiative cooling in clear‐sky, showing peaks larger than 5–10 K/day at the top of the boundary layer. A suite of novel scaling approximations is first developed from simplified spectral theory, in close agreement with the measurements. The radiative cooling peak height is set by the maximum lapse rate in water vapor path, and its magnitude is mainly controlled by the ratio of column relative humidity above and below the peak. We emphasize how elevated intrusions of moist air can reduce low‐level cooling, by sporadically shading the spectral range which effectively cools to space. The efficiency of this spectral shading depends both on water content and altitude of moist intrusions; its height dependence cannot be explained by the temperature difference between the emitting and absorbing layers, but by the decrease of water vapor extinction with altitude. This analytical work can help to narrow the search for low‐level cloud patterns sensitive to radiative‐convective feedbacks: the most organized patterns with largest cloud fractions occur in atmospheres below 10% relative humidity and feel the strongest low‐level cooling. This motivates further assessment of favorable conditions for radiative‐convective feedbacks and a robust quantification of corresponding shallow cloud dynamics in current and warmer climates.","lang":"eng"}],"ec_funded":1,"oa_version":"Published Version","day":"01","month":"06","status":"public","isi":1,"keyword":["General Earth and Planetary Sciences"],"title":"How moisture shapes low‐level radiative cooling in subsidence regimes","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","has_accepted_license":"1"},{"article_number":"137871","type":"journal_article","author":[{"last_name":"Faccioli","full_name":"Faccioli, Pietro","first_name":"Pietro"},{"last_name":"Krätschmer","id":"30d4014e-7753-11eb-b44b-db6d61112e73","full_name":"Krätschmer, Ilse","orcid":"0000-0002-5636-9259","first_name":"Ilse"},{"last_name":"Lourenço","full_name":"Lourenço, Carlos","first_name":"Carlos"}],"file_date_updated":"2024-01-09T08:59:24Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"citation":{"apa":"Faccioli, P., Krätschmer, I., &#38; Lourenço, C.

The domain size, shape and spatial resolution have been varied and the results compared with those in a sufficiently large computational orthogonal domain with natural axial and azimuthal periodicity. We find that a minimal parallelogram of the right tilt significantly reduces the computational cost without notably compromising the statistical properties of the supercritical turbulent spiral.

Furthermore, using these flexible game solvers as a back-end, we implemented a tool for computing correct-by-construction controllers for stochastic dynamical systems under LTL specifications. Our implementations use the recent theoretical result that all of these games can be solved using the same symbolic fixpoint algorithm but utilizing different, domain specific calculations of the involved predecessor operators. The main feature of our toolchain is the utilization of two programming abstractions: one to separate the symbolic fixpoint computations from the predecessor calculations, and another one to allow the integration of different BDD libraries as back-ends. In particular, we employ a multi-threaded execution of the fixpoint algorithm by using the multi-threaded BDD library Sylvan, which leads to enormous computational savings."}],"ec_funded":1,"project":[{"name":"Vigilant Algorithmic Monitoring of Software","call_identifier":"H2020","_id":"62781420-2b32-11ec-9570-8d9b63373d4d","grant_number":"101020093"}],"department":[{"_id":"ToHe"}],"corr_author":"1","isi":1,"status":"public","month":"07","related_material":{"record":[{"relation":"research_data","id":"14994","status":"public"}]},"day":"16","has_accepted_license":"1","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","title":"A flexible toolchain for symbolic rabin games under fair and stochastic uncertainties","publication_status":"published","date_created":"2024-01-08T13:18:00Z","year":"2023","article_processing_charge":"Yes (in subscription journal)","scopus_import":"1","doi":"10.1007/978-3-031-37709-9_1","fulldoi":"https://doi.org/10.1007/978-3-031-37709-9_1","date_published":"2023-07-16T00:00:00Z","publication":"35th International Conference on Computer Aided Verification","quality_controlled":"1","date_updated":"2025-09-09T14:16:49Z","intvolume":"     13966"},{"date_created":"2024-01-09T16:20:09Z","publication_status":"published","year":"2023","scopus_import":"1","article_processing_charge":"No","doi":"10.1109/focs57990.2023.00066","fulldoi":"https://doi.org/10.1109/focs57990.2023.00066","date_published":"2023-12-22T00:00:00Z","publication":"2023 IEEE 64th Annual Symposium on Foundations of Computer Science","date_updated":"2025-09-09T14:17:59Z","quality_controlled":"1","external_id":{"arxiv":["2310.04076"],"isi":["001137125900060"]},"oa_version":"Preprint","ec_funded":1,"_id":"14768","abstract":[{"text":"In all state-of-the-art sketching and coreset techniques for clustering, as well as in the best known fixed-parameter tractable approximation algorithms, randomness plays a key role. For the classic k-median and k-means problems, there are no known deterministic dimensionality reduction procedure or coreset construction that avoid an exponential dependency on the input dimension d, the precision parameter $\\varepsilon^{-1}$ or k. Furthermore, there is no coreset construction that succeeds with probability $1-1/n$ and whose size does not depend on the number of input points, n. This has led researchers in the area to ask what is the power of randomness for clustering sketches [Feldman WIREs Data Mining Knowl. Discov’20].Similarly, the best approximation ratio achievable deterministically without a complexity exponential in the dimension are $1+\\sqrt{2}$ for k-median [Cohen-Addad, Esfandiari, Mirrokni, Narayanan, STOC’22] and 6.12903 for k-means [Grandoni, Ostrovsky, Rabani, Schulman, Venkat, Inf. Process. Lett.’22]. Those are the best results, even when allowing a complexity FPT in the number of clusters k: this stands in sharp contrast with the $(1+\\varepsilon)$-approximation achievable in that case, when allowing randomization.In this paper, we provide deterministic sketches constructions for clustering, whose size bounds are close to the best-known randomized ones. We show how to compute a dimension reduction onto $\\varepsilon^{-O(1)} \\log k$ dimensions in time $k^{O\\left(\\varepsilon^{-O(1)}+\\log \\log k\\right)}$ poly $(n d)$, and how to build a coreset of size $O\\left(k^{2} \\log ^{3} k \\varepsilon^{-O(1)}\\right)$ in time $2^{\\varepsilon^{O(1)} k \\log ^{3} k}+k^{O\\left(\\varepsilon^{-O(1)}+\\log \\log k\\right)}$ poly $(n d)$. In the case where k is small, this answers an open question of [Feldman WIDM’20] and [Munteanu and Schwiegelshohn, Künstliche Intell. ’18] on whether it is possible to efficiently compute coresets deterministically.We also construct a deterministic algorithm for computing $(1+$ $\\varepsilon)$-approximation to k-median and k-means in high dimensional Euclidean spaces in time $2^{k^{2} \\log ^{3} k / \\varepsilon^{O(1)}}$ poly $(n d)$, close to the best randomized complexity of $2^{(k / \\varepsilon)^{O(1)}}$ nd (see [Kumar, Sabharwal, Sen, JACM 10] and [Bhattacharya, Jaiswal, Kumar, TCS’18]).Furthermore, our new insights on sketches also yield a randomized coreset construction that uses uniform sampling, that immediately improves over the recent results of [Braverman et al. FOCS ’22] by a factor k.","lang":"eng"}],"project":[{"grant_number":"101034413","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","call_identifier":"H2020","name":"IST-BRIDGE: International postdoctoral program"},{"name":"The design and evaluation of modern fully dynamic data structures","call_identifier":"H2020","_id":"bd9ca328-d553-11ed-ba76-dc4f890cfe62","grant_number":"101019564"}],"department":[{"_id":"MoHe"}],"status":"public","isi":1,"month":"12","day":"22","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","title":"Deterministic clustering in high dimensional spaces: Sketches and approximation","acknowledgement":"D.

Here, the case of diagonally dominant block operator matrices is considered, that is, the case where the full operator A can be seen as a relatively bounded perturbation of its diagonal part with D(A)=D(A)×D(D) though with possibly large relative bound. For such operators the properties of sectoriality, R-sectoriality and the boundedness of the H∞-calculus are studied, and for these properties perturbation results for possibly large but structured perturbations are derived. Thereby, the time dependent parabolic problem associated with A can be analyzed in maximal Lpt\r\n-regularity spaces, and this is applied to a wide range of problems such as different theories for liquid crystals, an artificial Stokes system, strongly damped wave and plate equations, and a Keller-Segel model.","lang":"eng"}]},{"main_file_link":[{"url":"https://www.lmd.ens.fr/muller/Pubs/2023-MullerAbramianPhysToday.pdf","open_access":"1"}],"article_number":"28","issue":"5","type":"journal_article","author":[{"last_name":"Muller","id":"f978ccb0-3f7f-11eb-b193-b0e2bd13182b","full_name":"Muller, Caroline J","orcid":"0000-0001-5836-5350","first_name":"Caroline J"},{"full_name":"Abramian, Sophie","first_name":"Sophie","last_name":"Abramian"}],"citation":{"ista":"Muller CJ, Abramian S. 2023.

These soluble residents of the ER are themselves endowed with an ER retrieval signal that enables the cell to bring the escaped residents back from the Golgi. Here, by using purified proteins, we showed that Nicotiana tabacum phytaspase, a plant aspartate-specific protease, introduces two breaks at the C-terminus of the N. tabacum ER resident calreticulin-3. These cleavages resulted in removal of either a dipeptide or a hexapeptide from the C-terminus of calreticulin-3 encompassing part or all of the ER retrieval signal. Consistently, expression of the calreticulin-3 derivative mimicking the phytaspase cleavage product in Nicotiana benthamiana cells demonstrated loss of the ER accumulation of the protein. Notably, upon its escape from the ER, calreticulin-3 was further processed by an unknown protease(s) to generate the free N-terminal (N) domain of calreticulin-3, which was ultimately secreted into the apoplast. Our study thus identified a specific proteolytic enzyme capable of precise detachment of the ER retrieval signal from a plant ER resident protein, with implications for the further fate of the escaped resident."}],"_id":"14776","department":[{"_id":"JiFr"}],"corr_author":"1","keyword":["Inorganic Chemistry","Organic Chemistry","Physical and Theoretical Chemistry","Computer Science Applications","Spectroscopy","Molecular Biology","General Medicine","Catalysis"],"status":"public","isi":1,"day":"01","month":"11","has_accepted_license":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Phytaspase Is capable of detaching the endoplasmic reticulum retrieval signal from tobacco calreticulin-3","file":[{"relation":"main_file","checksum":"4df7d206ba022b7f54eff1f0aec1659a","content_type":"application/pdf","date_created":"2024-01-10T13:39:42Z","access_level":"open_access","date_updated":"2024-01-10T13:39:42Z","file_name":"2023_IJMS_Teplova.pdf","file_size":2637784,"success":1,"creator":"dernst","file_id":"14791"}],"acknowledgement":"We thank C.U.T.

Density functional theory calculations predict that such a partial V-substitution constructively modifies the electronic structure near the bottom of the conduction band to improve the TE performance. The synthesized Ag1.97V0.03S0.55Se0.45 is found to possess a TE dimensionless figure-of-merit (ZT) of 0.71 at 350 K with maintaining its flexible nature. This ZT value is relatively high in comparison with those reported for flexible TE materials below 360 K. The increase in the ZT value is caused by the enhanced absolute value of the Seebeck coefficient with less significant variation in electrical resistivity. The high ZT value with the flexible nature naturally allows us to employ the Ag1.97V0.03S0.55Se0.45 as a component of flexible TE generators.","lang":"eng"}],"department":[{"_id":"MaIb"}],"external_id":{"isi":["001114917200005"]},"has_accepted_license":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Improvement of thermoelectric performance of flexible compound Ag2S0.55Se0.45 by means of partial V-substitution for Ag","corr_author":"1","keyword":["General Physics and Astronomy"],"status":"public","isi":1,"month":"12","day":"01"},{"corr_author":"1","keyword":["Theoretical Computer Science","Software"],"month":"06","related_material":{"record":[{"status":"public","relation":"earlier_version","id":"10414"}]},"day":"23","isi":1,"status":"public","has_accepted_license":"1","title":"On lexicographic proof rules for probabilistic termination","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","external_id":{"isi":["001035915800006"],"arxiv":["2108.02188"]},"_id":"14778","abstract":[{"lang":"eng","text":"We consider the almost-sure (a.s.) termination problem for probabilistic programs, which are a stochastic extension of classical imperative programs. Lexicographic ranking functions provide a sound and practical approach for termination of non-probabilistic programs, and their extension to probabilistic programs is achieved via lexicographic ranking supermartingales (LexRSMs). However, LexRSMs introduced in the previous work have a limitation that impedes their automation: all of their components have to be non-negative in all reachable states. This might result in a LexRSM not existing even for simple terminating programs. Our contributions are twofold. First, we introduce a generalization of LexRSMs that allows for some components to be negative. This standard feature of non-probabilistic termination proofs was hitherto not known to be sound in the probabilistic setting, as the soundness proof requires a careful analysis of the underlying stochastic process. Second, we present polynomial-time algorithms using our generalized LexRSMs for proving a.s. termination in broad classes of linear-arithmetic programs."}],"ec_funded":1,"oa_version":"Published Version","project":[{"grant_number":"863818","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","call_identifier":"H2020","name":"Formal Methods for Stochastic Models: Algorithms and Applications"},{"name":"International IST Doctoral Program","call_identifier":"H2020","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","grant_number":"665385"}],"department":[{"_id":"KrCh"}],"date_published":"2023-06-23T00:00:00Z","publication":"Formal Aspects of Computing","date_updated":"2025-09-09T14:19:27Z","quality_controlled":"1","intvolume":"        35","article_type":"original","date_created":"2024-01-10T09:27:43Z","publication_status":"published","year":"2023","scopus_import":"1","article_processing_charge":"Yes","fulldoi":"https://doi.org/10.1145/3585391","doi":"10.1145/3585391","article_number":"11","issue":"2","type":"journal_article","author":[{"first_name":"Krishnendu","orcid":"0000-0002-4561-241X","full_name":"Chatterjee, Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","last_name":"Chatterjee"},{"last_name":"Kafshdar Goharshady","full_name":"Kafshdar Goharshady, Ehsan","first_name":"Ehsan"},{"last_name":"Novotný","first_name":"Petr","id":"3CC3B868-F248-11E8-B48F-1D18A9856A87","full_name":"Novotný, Petr"},{"full_name":"Zárevúcky, Jiří","first_name":"Jiří","last_name":"Zárevúcky"},{"first_name":"Dorde","orcid":"0000-0002-4681-1699","full_name":"Zikelic, Dorde","id":"294AA7A6-F248-11E8-B48F-1D18A9856A87","last_name":"Zikelic"}],"file_date_updated":"2024-01-16T08:11:24Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"citation":{"ama":"Chatterjee K, Kafshdar Goharshady E, Novotný P, Zárevúcky J, Zikelic D.

To test this hypothesis, we explore six years of distributed meteorological data on a small Swiss glacier in the period 2001–2022. Large glacier fragmentation has occurred since 2001 (−35% area change up to 2022) coinciding with notable frontal retreat, an observed switch from down‐glacier katabatic to up‐glacier valley winds and an increased sensitivity (ratio) of on‐glacier to off‐glacier temperature. As the glacier ceases to develop density‐driven katabatic winds, sensible heat fluxes on the glacier are increasingly determined by the conditions occurring outside the boundary layer of the glacier, sealing the glacier's demise as the climate continues to warm and experience an increased frequency of extreme summers."}],"oa_version":"Published Version","department":[{"_id":"FrPe"}],"external_id":{"isi":["000999436400001"]}},{"file_date_updated":"2024-01-16T08:47:31Z","author":[{"first_name":"Xiucai","full_name":"Ding, Xiucai","last_name":"Ding"},{"id":"dd216c0a-c1f9-11eb-beaf-e9ea9d2de76d","full_name":"Ji, Hong Chang","first_name":"Hong Chang","last_name":"Ji"}],"citation":{"ama":"Ding X, Ji HC.

Combining three-dimensional in vivo structural and functional analyses, we study the dynamic spatial organization of molecules within zebrafish germ granules. We find that the localization of RNA molecules to the periphery of the granules, where ribosomes are localized, depends on translational activity at this location. In addition, we find that the vertebrate-specific Dead end (Dnd1) protein is essential for nanos3 RNA localization at the condensates’ periphery. Accordingly, in the absence of Dnd1, or when translation is inhibited, nanos3 RNA translocates into the granule interior, away from the ribosomes, a process that is correlated with the loss of germ cell fate. These findings highlight the relevance of sub-granule compartmentalization for post-transcriptional control and its importance for preserving germ cell totipotency.","lang":"eng"}],"department":[{"_id":"Bio"}],"external_id":{"pmid":["37463577"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Spatial organization and function of RNA molecules within phase-separated condensates in zebrafish are controlled by Dnd1","keyword":["Developmental Biology","Cell Biology","General Biochemistry","Genetics and Molecular Biology","Molecular Biology"],"status":"public","day":"11","month":"09","article_processing_charge":"No","doi":"10.1016/j.devcel.2023.06.009","fulldoi":"https://doi.org/10.1016/j.devcel.2023.06.009","date_created":"2024-01-10T09:41:21Z","publication_status":"published","article_type":"original","year":"2023","quality_controlled":"1","date_updated":"2024-01-16T08:56:36Z","intvolume":"        58","date_published":"2023-09-11T00:00:00Z","pmid":1,"publication":"Developmental Cell","author":[{"last_name":"Westerich","full_name":"Westerich, Kim Joana","first_name":"Kim Joana"},{"last_name":"Tarbashevich","first_name":"Katsiaryna","full_name":"Tarbashevich, Katsiaryna"},{"last_name":"Schick","first_name":"Jan","full_name":"Schick, Jan"},{"last_name":"Gupta","full_name":"Gupta, Antra","first_name":"Antra"},{"last_name":"Zhu","first_name":"Mingzhao","full_name":"Zhu, Mingzhao"},{"last_name":"Hull","full_name":"Hull, Kenneth","first_name":"Kenneth"},{"first_name":"Daniel","full_name":"Romo, Daniel","last_name":"Romo"},{"full_name":"Zeuschner, Dagmar","first_name":"Dagmar","last_name":"Zeuschner"},{"last_name":"Goudarzi","first_name":"Mohammad","full_name":"Goudarzi, Mohammad","id":"3384113A-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Gross-Thebing","first_name":"Theresa","full_name":"Gross-Thebing, Theresa"},{"first_name":"Erez","full_name":"Raz, Erez","last_name":"Raz"}],"citation":{"ieee":"K.

It must generate or adapt to plasma membrane curvature to facilitate diverse functions such as cell division, migration, and phagocytosis. Due to the complex molecular makeup of the actin cortex, it remains unclear whether actin networks are inherently able to sense and generate membrane curvature, or whether they rely on their diverse binding partners to accomplish this. Here, we show that curvature sensing is an inherent capability of branched actin networks nucleated by Arp2/3 and VCA. We develop a robust method to encapsulate actin inside giant unilamellar vesicles (GUVs) and assemble an actin cortex at the inner surface of the GUV membrane. We show that actin forms a uniform and thin cortical layer when present at high concentration and distinct patches associated with negative membrane curvature at low concentration. Serendipitously, we find that the GUV production method also produces dumbbell-shaped GUVs, which we explain using mathematical modeling in terms of membrane hemifusion of nested GUVs. We find that branched actin networks preferentially assemble at the neck of the dumbbells, which possess a micrometer-range convex curvature comparable with the curvature of the actin patches found in spherical GUVs. Minimal branched actin networks can thus sense membrane curvature, which may help mammalian cells to robustly recruit actin to curved membranes to facilitate diverse cellular functions such as cytokinesis and migration."}],"_id":"14782","oa_version":"Published Version","external_id":{"isi":["001016792600001"],"pmid":["36806830"]},"publisher":"Elsevier","ddc":["570"],"oa":1,"language":[{"iso":"eng"}],"page":"2311-2324","publication_identifier":{"issn":["0006-3495"]},"volume":122,"acknowledgement":"We thank Jeffrey den Haan for protein purification, Kristina Ganzinger (AMOLF) for providing the 10xHis VCA construct, David Kovar (University of Chicago) for the CP constructs, and Michael Way (Crick Institute) for providing purified human Arp2/3 proteins.

We have previously found that astroglial Cx43 controls synaptic glutamate levels and allows for activity-dependent glutamine release to sustain physiological synaptic transmissions and cognitiogns. However, whether Cx43 is important for the release of synaptic vesicles, which is a critical component of synaptic efficacy, remains unanswered. Here, using transgenic mice with a glial conditional knockout of Cx43 (Cx43−/−), we investigate whether and how astrocytes regulate the release of synaptic vesicles from hippocampal synapses. We report that CA1 pyramidal neurons and their synapses develop normally in the absence of astroglial Cx43. However, a significant impairment in synaptic vesicle distribution and release dynamics were observed. In particular, the FM1-43 assays performed using two-photon live imaging and combined with multi-electrode array stimulation in acute hippocampal slices, revealed a slower rate of synaptic vesicle release in Cx43−/− mice. Furthermore, paired-pulse recordings showed that synaptic vesicle release probability was also reduced and is dependent on glutamine supply via Cx43 hemichannel (HC). Taken together, we have uncovered a role for Cx43 in regulating presynaptic functions by controlling the rate and probability of synaptic vesicle release. Our findings further highlight the significance of astroglial Cx43 in synaptic transmission and efficacy.","lang":"eng"}],"oa_version":"Published Version","department":[{"_id":"SiHi"}],"external_id":{"pmid":["37190042"],"isi":["000977445700001"]},"has_accepted_license":"1","title":"Astroglial connexin 43 regulates synaptic vesicle release at hippocampal synapses","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","keyword":["General Medicine"],"month":"04","day":"11","isi":1,"status":"public","volume":12,"publication_identifier":{"issn":["2073-4409"]},"file":[{"access_level":"open_access","date_created":"2024-01-16T09:26:52Z","content_type":"application/pdf","relation":"main_file","checksum":"6798cd75d8857976fbc58a43fd173d68","success":1,"file_id":"14808","creator":"dernst","file_name":"2023_Cells_Cheung.pdf","date_updated":"2024-01-16T09:26:52Z","file_size":7931643}],"acknowledgement":"This research was funded by grants from the European Research Council (Consolidator grant #683154) and European Union’s Horizon 2020 research and innovation program (Marie Sklodowska-Curie Innovative Training Networks, grant #722053, EU-GliaPhD) to N.R., as well as from FP7-PEOPLE Marie Curie Intra-European Fellowship for career development (grant #622289) to G.C.

RNA sequencing of CD3+T cells revealed transcriptional alterations across all time points, with most changes occurring 14 days after DI exposure. At day 21, T cells showed evidence of adaptation with a transcriptional profile resembling that of 7 days before DI. At 7 days after DI, T cells again changed their transcriptional profile.
