However,\r\nmany DP algorithms have to fill in large DP tables, represented by two-dimensional arrays, which causes at least quadratic running times and space usages. This has led to the development of improved algorithms for special cases when the DPs satisfy additional properties like, e.g., the Monge property or total monotonicity.\r\nIn this paper, we consider a new condition which assumes (among some other technical assumptions) that the rows of the DP table are monotone. Under this assumption, we introduce\r\na novel data structure for computing (1 + ϵ)-approximate DP solutions in near-linear time and\r\nspace in the static setting, and with polylogarithmic update times when the DP entries change\r\ndynamically. To the best of our knowledge, our new condition is incomparable to previous conditions and is the first which allows to derive dynamic algorithms based on existing DPs. Instead of using two-dimensional arrays to store the DP tables, we store the rows of the DP tables using monotone piecewise constant functions. This allows us to store length-n DP table rows with entries in [0, W] using only polylog(n, W) bits, and to perform operations, such as (min, +)-convolution or rounding, on these functions in polylogarithmic time.\r\nWe further present several applications of our data structure. For bicriteria versions of k-balanced graph partitioning and simultaneous source location, we obtain the first dynamic algorithms with subpolynomial update times, as well as the first static algorithms using only near-linear time and space. Additionally, we obtain the currently fastest algorithm for fully dynamic knapsack.","lang":"eng"}],"scopus_import":"1","date_updated":"2023-03-27T06:46:27Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"status":"public","author":[{"last_name":"Henzinger","full_name":"Henzinger, Monika H","orcid":"0000-0002-5008-6530","first_name":"Monika H","id":"540c9bbd-f2de-11ec-812d-d04a5be85630"},{"first_name":"Stefan","last_name":"Neumann","full_name":"Neumann, Stefan"},{"full_name":"Räcke, Harald","last_name":"Räcke","first_name":"Harald"},{"first_name":"Stefan","last_name":"Schmid","full_name":"Schmid, Stefan"}],"citation":{"ama":"Henzinger MH, Neumann S, Räcke H, Schmid S.

Going beyond the well-studied tracial mode, Trf (W), which is equivalent to the customary linear statistics of eigenvalues, we show that Trf (W)A is asymptotically normal for any nontrivial bounded deterministic matrix A. We identify three different and asymptotically independent modes of this fluctuation, corresponding to the tracial part, the traceless diagonal part and the off-diagonal part of f (W) in the entire mesoscopic regime, where we find that the off-diagonal modes fluctuate on a much smaller scale than the tracial mode. As a main motivation to study CLT in such generality on small mesoscopic scales, we determine\r\nthe fluctuations in the eigenstate thermalization hypothesis (Phys. Rev. A 43 (1991) 2046–2049), that is, prove that the eigenfunction overlaps with any deterministic matrix are asymptotically Gaussian after a small spectral averaging. Finally, in the macroscopic regime our result also generalizes (Zh. Mat. Fiz. Anal. Geom. 9 (2013) 536–581, 611, 615) to complex W and to all crossover ensembles in between. The main technical inputs are the recent\r\nmultiresolvent local laws with traceless deterministic matrices from the companion paper (Comm. Math.

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"}],"scopus_import":"1","date_updated":"2023-08-16T12:41:53Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"status":"public","author":[{"orcid":"0000-0003-2623-5249","full_name":"Lombardi, Fabrizio","last_name":"Lombardi","id":"A057D288-3E88-11E9-986D-0CF4E5697425","first_name":"Fabrizio"},{"first_name":"Selver","id":"F93245C4-C3CA-11E9-B4F0-C6F4E5697425","last_name":"Pepic","full_name":"Pepic, Selver"},{"last_name":"Shriki","full_name":"Shriki, Oren","first_name":"Oren"},{"full_name":"Tkačik, Gašper","last_name":"Tkačik","orcid":"0000-0002-6699-1455","id":"3D494DCA-F248-11E8-B48F-1D18A9856A87","first_name":"Gašper"},{"orcid":"0000-0002-5214-4706","last_name":"De Martino","full_name":"De Martino, Daniele","first_name":"Daniele","id":"3FF5848A-F248-11E8-B48F-1D18A9856A87"}]},{"doi":"10.1007/s41468-023-00116-x","ec_funded":1,"article_processing_charge":"No","day":"01","acknowledgement":"We thank Eddie Aamari, David Cohen-Steiner, Isa Costantini, Fred Chazal, Ramsay Dyer, André Lieutier, and Alef Sterk for discussion and Pierre Pansu for encouragement.

Bangert showed that sets of positive reach in Euclidean space and Riemannian manifolds are very similar. In this paper we introduce a slight variant of Kleinjohann’s and Bangert’s extension and quantify the similarity between sets of positive reach in Euclidean space and Riemannian manifolds in a new way: Given p∈M and q∈S, we bound the local feature size (a local version of the reach) of its lifting to the tangent space via the inverse exponential map (exp−1p(S)) at q, assuming that rchM(S) and the geodesic distance dM(p,q) are bounded. These bounds are motivated by the importance of the reach and local feature size to manifold learning, topological inference, and triangulating manifolds and the fact that intrinsic approaches circumvent the curse of dimensionality.","lang":"eng"}],"project":[{"grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425","name":"ISTplus - Postdoctoral Fellowships","call_identifier":"H2020"},{"grant_number":"M03073","name":"Learning and triangulating manifolds via collapses","_id":"fc390959-9c52-11eb-aca3-afa58bd282b2"}],"month":"09","year":"2023","publication_identifier":{"issn":["2367-1726"],"eissn":["2367-1734"]},"article_type":"original","department":[{"_id":"HeEd"}],"publisher":"Springer Nature","publication_status":"published","_id":"12763","oa_version":"Submitted Version","type":"journal_article"},{"oa":1,"citation":{"mla":"Kourimska, Hana. “Discrete Yamabe Problem for Polyhedral Surfaces.” <i>Discrete and Computational Geometry</i>, vol. 70, Springer Nature, 2023, pp. 123–53, doi:<a href=\"https://doi.org/10.1007/s00454-023-00484-2\">10.1007/s00454-023-00484-2</a>.","apa":"Kourimska, H.

Complex I is the first and the largest enzyme of the respiratory chain which is essential for energy production. It couples the transfer of two electrons from NADH to ubiquinone with proton translocation across bacterial or inner mitochondrial membrane. The coupling mechanism between electron transfer and proton translocation is one of the biggest enigma in bioenergetics and structural biology. Even though the enzyme has been studied for decades, only recent technological advances in cryo-EM allowed its extensive structural investigation. \r\n\r\nComplex I from E.coli appears to be of special importance because it is a perfect model system with a rich mutant library, however the structure of the entire complex was unknown. In this thesis I have resolved structures of the minimal complex I version from E. coli in different states including reduced, inhibited, under reaction turnover and several others. Extensive structural analyses of these structures and comparison to structures from other species allowed to derive general features of conformational dynamics and propose a universal coupling mechanism. The mechanism is straightforward, robust and consistent with decades of experimental data available for complex I from different species. \r\n\r\nCyanobacterial NDH (cyanobacterial complex I) is a part of broad complex I superfamily and was studied as well in this thesis. It plays an important role in cyclic electron transfer (CET), during which electrons are cycled within PSI through ferredoxin and plastoquinone to generate proton gradient without NADPH production. Here, I solved structure of NDH and revealed additional state, which was not observed before. The novel “resting” state allowed to propose the mechanism of CET regulation. Moreover, conformational dynamics of NDH resembles one in complex I which suggest more broad universality of the proposed coupling mechanism.\r\n\r\nIn summary, results presented here helped to interpret decades of experimental data for complex I and contributed to fundamental mechanistic understanding of protein function.\r\n"}],"related_material":{"record":[{"id":"12138","status":"public","relation":"part_of_dissertation"}]},"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","language":[{"iso":"eng"}],"date_updated":"2023-08-04T08:54:51Z"},{"article_processing_charge":"No","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"file_date_updated":"2023-04-03T06:38:56Z","doi":"10.1038/s41467-023-37259-5","date_published":"2023-03-25T00:00:00Z","has_accepted_license":"1","intvolume":"        14","volume":14,"day":"25","acknowledgement":"We thank James Krieger for generating the ‘proDy’ interaction maps in Fig. 5B and S7C, and Jan-Niklas Dohrke for critically reading the manuscript.

Their signalling is uniquely diversified by brain region-specific auxiliary subunits, providing an opportunity for the development of selective therapeutics. AMPARs associated with TARP γ8 are enriched in the hippocampus, and are targets of emerging anti-epileptic drugs. To understand their therapeutic activity, we determined cryo-EM structures of the GluA1/2-γ8 receptor associated with three potent, chemically diverse ligands. We find that despite sharing a lipid-exposed and water-accessible binding pocket, drug action is differentially affected by binding-site mutants. Together with patch-clamp recordings and MD simulations we also demonstrate that ligand-triggered reorganisation of the AMPAR-TARP interface contributes to modulation. Unexpectedly, one ligand (JNJ-61432059) acts bifunctionally, negatively affecting GluA1 but exerting positive modulatory action on GluA2-containing AMPARs, in a TARP stoichiometry-dependent manner. These results further illuminate the action of TARPs, demonstrate the sensitive balance between positive and negative modulatory action, and provide a mechanistic platform for development of both positive and negative selective AMPAR modulators.","lang":"eng"}],"language":[{"iso":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2023-12-13T11:15:58Z","article_type":"original","department":[{"_id":"PeJo"}],"year":"2023","month":"03","isi":1,"publication_identifier":{"eissn":["2041-1723"]},"_id":"12786","publication_status":"published","external_id":{"isi":["001066658700003"]},"oa_version":"Published Version","type":"journal_article","ddc":["570"],"file":[{"date_created":"2023-04-03T06:38:56Z","success":1,"checksum":"0a97b31191432dae5853bbb5ccb7698d","file_size":2613996,"date_updated":"2023-04-03T06:38:56Z","access_level":"open_access","content_type":"application/pdf","relation":"main_file","file_id":"12797","creator":"dernst","file_name":"2023_NatureComm_Zhang.pdf"}],"publisher":"Springer Nature"},{"doi":"10.1098/rspa.2022.0685","file_date_updated":"2023-04-03T06:25:29Z","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"article_processing_charge":"No","ec_funded":1,"day":"29","publication":"Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences","acknowledgement":"J.S. and K.C. acknowledge support from the ERC CoG 863818 (ForM-SMArt)","volume":479,"has_accepted_license":"1","intvolume":"       479","date_published":"2023-03-29T00:00:00Z","title":"Coexistence times in the Moran process with environmental heterogeneity","oa":1,"article_number":"20220685","date_created":"2023-04-02T22:01:09Z","citation":{"apa":"Svoboda, J., Tkadlec, J., Kaveh, K., &#38; Chatterjee, K.

While a certain trait might bring a fitness advantage in some patch of the environment, a different trait might be advantageous in another patch. Here, we study the Moran birth–death process with two types of individuals in a population stretched across two patches of size N, each patch favouring one of the two types. We show that the long-term fate of such populations crucially depends on the migration rate μ\r\n between the patches. To classify the possible fates, we use the distinction between polynomial (short) and exponential (long) timescales. We show that when μ is high then one of the two types fixates on the whole population after a number of steps that is only polynomial in N. By contrast, when μ is low then each type holds majority in the patch where it is favoured for a number of steps that is at least exponential in N. Moreover, we precisely identify the threshold migration rate μ⋆ that separates those two scenarios, thereby exactly delineating the situations that support long-term coexistence of the two types. We also discuss the case of various cycle graphs and we present computer simulations that perfectly match our analytical results.","lang":"eng"}],"scopus_import":"1","publication_identifier":{"issn":["1364-5021"],"eissn":["1471-2946"]},"isi":1,"project":[{"_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","call_identifier":"H2020","name":"Formal Methods for Stochastic Models: Algorithms and Applications","grant_number":"863818"}],"year":"2023","month":"03","department":[{"_id":"KrCh"}],"article_type":"original","publisher":"The Royal Society","type":"journal_article","ddc":["000"],"oa_version":"Published Version","file":[{"date_created":"2023-04-03T06:25:29Z","checksum":"13953d349fbefcb5d21ccc6b303297eb","success":1,"file_size":827784,"date_updated":"2023-04-03T06:25:29Z","content_type":"application/pdf","access_level":"open_access","relation":"main_file","creator":"dernst","file_id":"12796","file_name":"2023_ProceedingsRoyalSocietyA_Svoboda.pdf"}],"external_id":{"isi":["000957125500002"]},"publication_status":"published","issue":"2271","_id":"12787"},{"oa":1,"article_number":"103202","date_created":"2023-04-02T22:01:10Z","citation":{"ama":"Karle V, Ghazaryan A, Lemeshko M.

A periodically kicked molecular rotor can be mapped onto a “crystalline” lattice in angular momentum space. This allows us to define quasimomenta and the band structure in the Floquet representation, by analogy with the Bloch waves of solid-state physics. Applying laser pulses spaced by 1/3 of the molecular rotational period creates a lattice with three atoms per unit cell with staggered hopping. Within the synthetic dimension of the laser strength, we discover Dirac cones with topological charges. These Dirac cones, topologically protected by reflection and time-reversal symmetry, are reminiscent of (although not equivalent to) that seen in graphene. They—and the corresponding edge states—are broadly tunable by adjusting the laser strength and can be observed in present-day experiments by measuring molecular alignment and populations of rotational levels. This paves the way to study controllable topological physics in gas-phase experiments with small molecules as well as to classify dynamical molecular states by their topological invariants."}],"scopus_import":"1","status":"public","author":[{"first_name":"Volker","id":"D7C012AE-D7ED-11E9-95E8-1EC5E5697425","last_name":"Karle","full_name":"Karle, Volker"},{"id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","first_name":"Areg","orcid":"0000-0001-9666-3543","last_name":"Ghazaryan","full_name":"Ghazaryan, Areg"},{"id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail","full_name":"Lemeshko, Mikhail","last_name":"Lemeshko","orcid":"0000-0002-6990-7802"}]},{"publisher":"American Physical Society","issue":"3","_id":"12789","external_id":{"isi":["000992142700001"]},"publication_status":"published","type":"journal_article","ddc":["530"],"file":[{"date_created":"2023-11-27T09:51:48Z","success":1,"file_size":1428631,"checksum":"48f5dfe4e5f1c46c3c86805cd8f84bea","date_updated":"2023-11-27T09:51:48Z","access_level":"open_access","content_type":"application/pdf","relation":"main_file","file_id":"14612","creator":"swaituka","file_name":"PhysRevE.107.034901 (1).pdf"}],"oa_version":"Published Version","month":"03","year":"2023","project":[{"grant_number":"949120","_id":"0aa60e99-070f-11eb-9043-a6de6bdc3afa","call_identifier":"H2020","name":"Tribocharge: a multi-scale approach to an enduring problem in physics"}],"isi":1,"publication_identifier":{"issn":["2470-0045"],"eissn":["2470-0053"]},"article_type":"original","department":[{"_id":"ScWa"}],"language":[{"iso":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2023-11-28T09:22:25Z","scopus_import":"1","abstract":[{"lang":"eng","text":"Experiments have shown that charge distributions of granular materials are non-Gaussian, with broad tails that indicate many particles with high charge. This observation has consequences for the behavior of granular materials in many settings, and may bear relevance to the underlying charge transfer mechanism. However, there is the unaddressed possibility that broad tails arise due to experimental uncertainties, as determining the shapes of tails is nontrivial. Here we show that measurement uncertainties can indeed account for most of the tail broadening previously observed. The clue that reveals this is that distributions are sensitive to the electric field at which they are measured; ones measured at low (high) fields have larger (smaller) tails. Accounting for sources of uncertainty, we reproduce this broadening in silico. Finally, we use our results to back out the true charge distribution without broadening, which we find is still non-Guassian, though with substantially different behavior at the tails and indicating significantly fewer highly charged particles. These results have implications in many natural settings where electrostatic interactions, especially among highly charged particles, strongly affect granular behavior."}],"author":[{"first_name":"Nicolás","last_name":"Mujica","full_name":"Mujica, Nicolás"},{"first_name":"Scott R","id":"3A1FFC16-F248-11E8-B48F-1D18A9856A87","full_name":"Waitukaitis, Scott R","last_name":"Waitukaitis","orcid":"0000-0002-2299-3176"}],"status":"public","article_number":"034901","oa":1,"quality_controlled":"1","acknowledged_ssus":[{"_id":"M-Shop"}],"citation":{"apa":"Mujica, N., &#38; Waitukaitis, S.

To this end, we study the density of states of multilayer graphene with up to four layers at the single-particle band structure level in the presence of a transverse electric field. Among the considered structures, tetralayer graphene with rhombohedral (ABCA) stacking reaches the highest density of states. We study the phases that can arise in ABCA graphene by tuning the carrier density and transverse electric field. For a broad region of the tuning parameters, the presence of strong Coulomb repulsion leads to a spontaneous spin and valley symmetry breaking via Stoner transitions. Using a model that incorporates the spontaneous spin and valley polarization, we explore the Kohn-Luttinger mechanism for superconductivity driven by repulsive Coulomb interactions. We find that the strongest superconducting instability is in the p-wave channel, and occurs in proximity to the onset of Stoner transitions. Interestingly, we find a range of densities and transverse electric fields where superconductivity develops out of a strongly corrugated, singly connected Fermi surface in each valley, leading to a topologically nontrivial chiral p+ip superconducting state with an even number of copropagating chiral Majorana edge modes. Our work establishes ABCA-stacked tetralayer graphene as a promising platform for observing strongly correlated physics and topological superconductivity.","lang":"eng"}],"related_material":{"link":[{"url":"https://ista.ac.at/en/news/reaching-superconductivity-layer-by-layer/","relation":"press_release","description":"News on the ISTA website"}]},"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2211.02492"}],"scopus_import":"1","date_updated":"2023-08-01T13:59:29Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","language":[{"iso":"eng"}],"author":[{"orcid":"0000-0001-9666-3543","last_name":"Ghazaryan","full_name":"Ghazaryan, Areg","first_name":"Areg","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Holder","full_name":"Holder, Tobias","first_name":"Tobias"},{"first_name":"Erez","last_name":"Berg","full_name":"Berg, Erez"},{"full_name":"Serbyn, Maksym","last_name":"Serbyn","orcid":"0000-0002-2399-5827","id":"47809E7E-F248-11E8-B48F-1D18A9856A87","first_name":"Maksym"}],"status":"public","oa_version":"Preprint","type":"journal_article","issue":"10","_id":"12790","publication_status":"published","external_id":{"isi":["000945526400003"],"arxiv":["2211.02492"]},"publisher":"American Physical Society","department":[{"_id":"MaSe"},{"_id":"MiLe"}],"article_type":"original","isi":1,"publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"month":"03","year":"2023"},{"external_id":{"isi":["000956387200001"],"arxiv":["2301.07769"]},"publication_status":"published","_id":"12791","issue":"3","oa_version":"Preprint","type":"journal_article","publisher":"Springer Nature","article_type":"original","department":[{"_id":"CaMu"}],"year":"2023","month":"03","publication_identifier":{"eissn":["1292-895X"],"issn":["1292-8941"]},"isi":1,"scopus_import":"1","main_file_link":[{"open_access":"1","url":" https://doi.org/10.48550/arXiv.2301.07769"}],"abstract":[{"lang":"eng","text":"We investigate the capabilities of Physics-Informed Neural Networks (PINNs) to reconstruct turbulent Rayleigh–Bénard flows using only temperature information.

We rigorously prove the physics prediction on SFF up to an intermediate time scale for a large class of random matrices using a robust method, the multi-resolvent local laws. Beyond Wigner matrices we also consider the monoparametric ensemble and prove that universality of SFF can already be triggered by a single random parameter, supplementing the recently proven Wigner–Dyson universality (Cipolloni et al. in Probab Theory Relat Fields, 2021. https://doi.org/10.1007/s00440-022-01156-7) to larger spectral scales.

Evolutionary pathways are neither directed nor deterministic, but rather an interplay between selection, migration, mutation, genetic drift and other environmental factors. Hybrid zones, as natural crossing experiments, offer a great opportunity to use cline analysis to deduce different evolutionary processes - for example, selection strength. Theoretical cline models, largely assuming uniform distribution of individuals, often lack the capability of incorporating population structure. Since in reality organisms mostly live in patchy distributions and their dispersal is hardly ever Gaussian, it is necessary to unravel the effect of these different elements of population structure on cline parameters and shape. In this thesis, I develop a simulation inspired by the A. majus hybrid zone of a single selected locus under frequency dependent selection. This simulation enables us to untangle the effects of different elements of population structure as for example a low-density center and long-range dispersal. This thesis is therefore a first step towards theoretically untangling the effects of different elements of population structure on cline parameters and shape.

Inspired by the discovery that mutations in SLC7A5, a transporter of metabolically essential large neutral amino acids (LNAAs), lead to autism, we employed metabolomic profiling to study the metabolic states of the cerebral cortex across different developmental stages. We found that the forebrain undergoes significant metabolic remodeling throughout development, with certain groups of metabolites showing stage-specific changes, but what are the consequences of perturbing this metabolic program? By manipulating Slc7a5 expression in neural cells, we found that the metabolism of LNAAs and lipids are interconnected in the cortex. Deletion of Slc7a5 in neurons affects the postnatal metabolic state, leading to a shift in lipid metabolism. Additionally, it causes stage- and cell-type-specific alterations in neuronal activity patterns, resulting in a long-term circuit dysfunction."}],"keyword":["General Biochemistry","Genetics and Molecular Biology"],"related_material":{"link":[{"url":"https://ista.ac.at/en/news/feed-them-or-lose-them/","relation":"press_release","description":"News on ISTA Website"}],"record":[{"status":"public","relation":"dissertation_contains","id":"13107"}]},"scopus_import":"1","date_updated":"2024-02-07T08:03:32Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","language":[{"iso":"eng"}],"title":"Large neutral amino acid levels tune perinatal neuronal excitability and survival","page":"1950-1967.e25","date_created":"2023-04-05T08:15:40Z","acknowledged_ssus":[{"_id":"PreCl"},{"_id":"EM-Fac"},{"_id":"Bio"},{"_id":"LifeSc"}],"citation":{"chicago":"Knaus, Lisa, Bernadette Basilico, Daniel Malzl, Maria Gerykova Bujalkova, Mateja Smogavec, Lena A.

Already Pavlov (1927) in his early days has used his classic\r\nconditioning experiments to study the neural mechanisms governing behavioral adaptation.\r\nWhat was not known back then was that the part of the brain that is largely responsible for\r\nthis type of associative learning is the cerebellum.\r\nSince then, plenty of theories on cerebellar learning have emerged. Despite their differences,\r\none thing they all have in common is that learning relies on synaptic and intrinsic plasticity.\r\nThe goal of my PhD project was to unravel the molecular mechanisms underlying synaptic\r\nplasticity in two synapses that have been shown to be implicated in motor learning, in an\r\neffort to understand how learning and memory formation are processed in the cerebellum.\r\nOne of the earliest and most well-known cerebellar theories postulates that motor learning\r\nlargely depends on long-term depression at the parallel fiber-Purkinje cell (PC-PC) synapse.\r\nHowever, the discovery of other types of plasticity in the cerebellar circuitry, like long-term\r\npotentiation (LTP) at the PC-PC synapse, potentiation of molecular layer interneurons (MLIs),\r\nand plasticity transfer from the cortex to the cerebellar/ vestibular nuclei has increased the\r\npopularity of the idea that multiple sites of plasticity might be involved in learning.\r\nStill a lot remains unknown about the molecular mechanisms responsible for these types of\r\nplasticity and whether they occur during physiological learning.\r\nIn the first part of this thesis we have analyzed the variation and nanodistribution of voltagegated calcium channels (VGCCs) and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid\r\ntype glutamate receptors (AMPARs) on the parallel fiber-Purkinje cell synapse after vestibuloocular reflex phase reversal adaptation, a behavior that has been suggested to rely on PF-PC\r\nLTP. We have found that on the last day of adaptation there is no learning trace in form of\r\nVGCCs nor AMPARs variation at the PF-PC synapse, but instead a decrease in the number of\r\nPF-PC synapses. These data seem to support the view that learning is only stored in the\r\ncerebellar cortex in an initial learning phase, being transferred later to the vestibular nuclei.\r\nNext, we have studied the role of MLIs in motor learning using a relatively simple and well characterized behavioral paradigm – horizontal optokinetic reflex (HOKR) adaptation. We\r\nhave found behavior-induced MLI potentiation in form of release probability increase that\r\ncould be explained by the increase of VGCCs at the presynaptic side. Our results strengthen\r\nthe idea of distributed cerebellar plasticity contributing to learning and provide a novel\r\nmechanism for release probability increase.

However, it has been hindered by insufficient 3D-resolution, inadequate signal-to-noise-ratio, and prohibitive light burden in optical imaging, whereas electron microscopy is inherently static. Here we solved these challenges by developing an integrated optical/machine learning technology, LIONESS (Live Information-Optimized Nanoscopy Enabling Saturated Segmentation). It leverages optical modifications to stimulated emission depletion (STED) microscopy in comprehensively, extracellularly labelled tissue and prior information on sample structure via machine learning to simultaneously achieve isotropic super-resolution, high signal-to-noise-ratio, and compatibility with living tissue. This allows dense deep-learning-based instance segmentation and 3D-reconstruction at synapse level incorporating molecular, activity, and morphodynamic information. LIONESS opens up avenues for studying the dynamic functional (nano-)architecture of living brain tissue.","lang":"eng"}],"has_accepted_license":"1","related_material":{"record":[{"status":"public","relation":"used_in_publication","id":"13267"}]},"file_date_updated":"2023-05-18T19:51:52Z","doi":"10.15479/AT:ISTA:12817","license":"https://creativecommons.org/licenses/by-sa/4.0/","author":[{"orcid":"0000-0001-8559-3973","full_name":"Danzl, Johann G","last_name":"Danzl","first_name":"Johann G","id":"42EFD3B6-F248-11E8-B48F-1D18A9856A87"}],"article_processing_charge":"No","tmp":{"short":"CC BY-SA (4.0)","legal_code_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","name":"Creative Commons Attribution-ShareAlike 4.0 International Public License (CC BY-SA 4.0)","image":"/images/cc_by_sa.png"},"status":"public","oa":1,"publisher":"Institute of Science and Technology Austria","_id":"12817","date_created":"2023-04-07T11:37:40Z","acknowledged_ssus":[{"_id":"ScienComp"},{"_id":"Bio"},{"_id":"PreCl"},{"_id":"LifeSc"},{"_id":"M-Shop"},{"_id":"E-Lib"}],"citation":{"apa":"Danzl, J.

In these settings, cells establish supracellular patterns of motion, including collective rotation and invasion. While such collective modes have been studied extensively in flat systems, the consequences of geometrical and topological constraints on collective migration in curved systems are largely unknown. Here, we discover a collective mode of cell migration in rotating spherical tissues manifesting as a propagating single-wavelength velocity wave. This wave is accompanied by an apparently incompressible supracellular flow pattern featuring topological defects as dictated by the spherical topology. Using a minimal active particle model, we reveal that this collective mode arises from the effect of curvature on the active flocking behavior of a cell layer confined to a spherical surface. Our results thus identify curvature-induced velocity waves as a mode of collective cell migration, impacting the dynamical organization of 3D curved tissues.","lang":"eng"}],"language":[{"iso":"eng"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","date_updated":"2023-08-01T14:05:30Z","title":"Curvature induces active velocity waves in rotating spherical tissues","quality_controlled":"1","date_created":"2023-04-09T22:01:00Z","citation":{"ama":"Brandstätter T, Brückner D, Han YL, Alert R, Guo M, Broedersz CP.

In this Letter, we experimentally demonstrate that in a single-atom maser based on a transmon strongly coupled to two resonators, it is possible to pump over a dozen photons into the system. The first high-quality resonator plays the role of a usual lasing cavity, and the second one presents a controlled dissipation channel, bolstering population inversion, and modifies the energy-level structure to lift the blockade. As confirmation of the lasing action, we observe conventional laser features such as a narrowing of the emission linewidth and external signal amplification. Additionally, we report unique single-atom features: self-quenching and several lasing thresholds."}],"status":"public","author":[{"first_name":"Alesya","id":"2d0a0600-edfb-11eb-afb5-c0f5fa7f4f3a","last_name":"Sokolova","full_name":"Sokolova, Alesya","orcid":"0000-0002-8308-4144"},{"full_name":"Kalacheva, D.
