However, regularization is generally achieved by indirect means, largely due to the complex set of functions defined by a network and the difficulty in measuring function complexity. There exists no method in the literature for additive regularization based on a norm of the function, as is classically considered in statistical learning theory. In this work, we study the tractability of function norms for deep neural networks with ReLU activations. We provide, to the best of our knowledge, the first proof in the literature of the NP-hardness of computing function norms of DNNs of 3 or more layers. We also highlight a fundamental difference between shallow and deep networks. In the light on these results, we propose a new regularization strategy based on approximate function norms, and show its efficiency on a segmentation task with a DNN.","lang":"eng"}],"scopus_import":"1","date_published":"2019-10-01T00:00:00Z","doi":"10.1109/ICCVW.2019.00097","status":"public","author":[{"last_name":"Rannen-Triki","full_name":"Rannen-Triki, Amal","first_name":"Amal"},{"first_name":"Maxim","full_name":"Berman, Maxim","last_name":"Berman"},{"full_name":"Kolmogorov, Vladimir","last_name":"Kolmogorov","id":"3D50B0BA-F248-11E8-B48F-1D18A9856A87","first_name":"Vladimir"},{"first_name":"Matthew B.","full_name":"Blaschko, Matthew B.","last_name":"Blaschko"}],"article_processing_charge":"No"},{"doi":"10.1109/ICCVW.2019.00217","ec_funded":1,"article_processing_charge":"No","publication":"Proceedings of the 2019 International Conference on Computer Vision Workshop","day":"01","date_published":"2019-10-01T00:00:00Z","title":"Detecting visual relationships using box attention","oa":1,"article_number":"1749-1753","date_created":"2020-04-05T22:00:51Z","citation":{"ama":"Kolesnikov A, Kuznetsova A, Lampert C, Ferrari V.

Our main novelty is a Box Attention mechanism that allows to model pairwise interactions between objects using standard object detection pipelines. The resulting model is conceptually clean, expressive and relies on well-justified training and prediction procedures. Moreover, unlike previously proposed approaches, our model does not introduce any additional complex components or hyperparameters on top of those already required by the underlying detection model.

Despite numerous studies on the effect of nectar robbing on components of plant fitness, its contribution to reproductive isolation is unclear. We experimentally tested the impact of different pollinator strategies in a natural hybrid zone between two subspecies of Antirrhinum majus with alternate flower colour guides. On either side of a steep cline in flower colour between Antirrhinum majus pseudomajus (magenta) and A. m. striatum (yellow), we quantified the behaviour of all floral visitors at different time points during the flowering season. Using long-run camera surveys, we quantify the impact of nectar robbing on the number of flowers visited per inflorescence and the flower probing time. We further experimentally tested the effect of nectar robbing on female reproductive success by manipulating the intensity of robbing. While robbing increased over time the number of legitimate visitors tended to decrease concomitantly. We found that the number of flowers pollinated on a focal inflorescence decreased with the number of prior robbing events. However, in the manipulative experiment, fruit set and fruit volume did not vary significantly between low robbing and control treatments. Our findings challenge the idea that robbers have a negative impact on plant fitness through female function. This study also adds to our understanding of the components of pollinator-mediated reproductive isolation and the maintenance of Antirrhinum hybrid zones.","lang":"eng"}],"scopus_import":"1"},{"author":[{"first_name":"Nicoletta","id":"2A003F6C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8451-1195","full_name":"Petridou, Nicoletta","last_name":"Petridou"},{"first_name":"Silvia","last_name":"Grigolon","full_name":"Grigolon, Silvia"},{"full_name":"Salbreux, Guillaume","last_name":"Salbreux","first_name":"Guillaume"},{"orcid":"0000-0001-6005-1561","full_name":"Hannezo, Edouard B","last_name":"Hannezo","id":"3A9DB764-F248-11E8-B48F-1D18A9856A87","first_name":"Edouard B"},{"id":"39427864-F248-11E8-B48F-1D18A9856A87","first_name":"Carl-Philipp J","orcid":"0000-0002-0912-4566","full_name":"Heisenberg, Carl-Philipp J","last_name":"Heisenberg"}],"status":"public","date_updated":"2023-09-11T14:03:28Z","language":[{"iso":"eng"}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","abstract":[{"lang":"eng","text":"Tissue morphogenesis is driven by mechanical forces that elicit changes in cell size, shape and motion. The extent by which forces deform tissues critically depends on the rheological properties of the recipient tissue. Yet, whether and how dynamic changes in tissue rheology affect tissue morphogenesis and how they are regulated within the developing organism remain unclear. Here, we show that blastoderm spreading at the onset of zebrafish morphogenesis relies on a rapid, pronounced and spatially patterned tissue fluidization. Blastoderm fluidization is temporally controlled by mitotic cell rounding-dependent cell–cell contact disassembly during the last rounds of cell cleavages. Moreover, fluidization is spatially restricted to the central blastoderm by local activation of non-canonical Wnt signalling within the blastoderm margin, increasing cell cohesion and thereby counteracting the effect of mitotic rounding on contact disassembly. Overall, our results identify a fluidity transition mediated by loss of cell cohesion as a critical regulator of embryo morphogenesis."}],"related_material":{"link":[{"description":"News on IST Homepage","url":"https://ist.ac.at/en/news/when-a-fish-becomes-fluid/","relation":"press_release"}]},"scopus_import":"1","isi":1,"publication_identifier":{"issn":["14657392"]},"month":"02","year":"2019","project":[{"_id":"260F1432-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"Interaction and feedback between cell mechanics and fate specification in vertebrate gastrulation","grant_number":"742573"},{"name":"Molecular mechanism of auxindriven formative divisions delineating lateral root organogenesis in plants (EMBO fellowship)","_id":"253E54C8-B435-11E9-9278-68D0E5697425","grant_number":"ALTF710-2016"}],"department":[{"_id":"CaHe"},{"_id":"EdHa"}],"article_type":"original","publisher":"Nature Publishing Group","oa_version":"Submitted Version","file":[{"date_updated":"2020-10-21T07:18:35Z","content_type":"application/pdf","access_level":"open_access","date_created":"2020-10-21T07:18:35Z","checksum":"e38523787b3bc84006f2793de99ad70f","success":1,"file_size":71590590,"file_name":"2018_NatureCellBio_Petridou_accepted.pdf","relation":"main_file","creator":"dernst","file_id":"8685"}],"ddc":["570"],"type":"journal_article","_id":"5789","external_id":{"pmid":["30559456"],"isi":["000457468300011"]},"publication_status":"published","doi":"10.1038/s41556-018-0247-4","file_date_updated":"2020-10-21T07:18:35Z","ec_funded":1,"article_processing_charge":"No","volume":21,"publication":"Nature Cell Biology","day":"01","pmid":1,"intvolume":"        21","has_accepted_license":"1","date_published":"2019-02-01T00:00:00Z","page":"169–178","title":"Fluidization-mediated tissue spreading by mitotic cell rounding and non-canonical Wnt signalling","oa":1,"citation":{"ieee":"N.

The question is whether one can extend R′ to a representation R of the entire graph G, that is, whether one can draw the remaining chords into a partially predrawn representation to obtain a representation of G. Our main result is an O(n3) time algorithm for partial representation extension of circle graphs, where n is the number of vertices.

Reference memory update led to the reward-directed place field shifts at newly rewarded arms and to the gradual strengthening of firing in passes between newly rewarded arms but not between those passes that included a familiar-rewarded arm. At the maze center, transient network synchronization periods preferentially replayed trajectories of the next chosen arm in reference memory tasks but the previously visited arm in the working memory task. Hence, reference memory demand was uniquely associated with a gradual, goal novelty-related reorganization of place cell assemblies and with trajectory replay that reflected the animal's decision of which arm to visit next.","lang":"eng"}],"main_file_link":[{"url":"https://www.doi.org/10.1016/j.neuron.2018.11.015","open_access":"1"}],"related_material":{"record":[{"relation":"dissertation_contains","status":"public","id":"837"}],"link":[{"url":"https://ist.ac.at/en/news/reading-rats-minds/","relation":"press_release","description":"News on IST Homepage"}]},"author":[{"first_name":"Haibing","id":"310349D0-F248-11E8-B48F-1D18A9856A87","full_name":"Xu, Haibing","last_name":"Xu"},{"id":"361CC00E-F248-11E8-B48F-1D18A9856A87","first_name":"Peter","full_name":"Baracskay, Peter","last_name":"Baracskay"},{"id":"426376DC-F248-11E8-B48F-1D18A9856A87","first_name":"Joseph","full_name":"O'Neill, Joseph","last_name":"O'Neill"},{"first_name":"Jozsef L","id":"3FA14672-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-5193-4036","last_name":"Csicsvari","full_name":"Csicsvari, Jozsef L"}],"status":"public","publisher":"Elsevier","issue":"1","_id":"5828","external_id":{"isi":["000454791500014"]},"publication_status":"published","oa_version":"Published Version","type":"journal_article","year":"2019","month":"01","project":[{"_id":"257A4776-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","name":"Memory-related information processing in neuronal circuits of the hippocampus and entorhinal cortex","grant_number":"281511"}],"isi":1,"publication_identifier":{"issn":["10974199"]},"article_type":"original","department":[{"_id":"JoCs"}]},{"oa_version":"Published Version","ddc":["530"],"type":"journal_article","file":[{"checksum":"255e42f957a8e2b10aad2499c750a8d6","file_size":859846,"date_created":"2019-01-28T15:27:17Z","access_level":"open_access","content_type":"application/pdf","date_updated":"2020-07-14T12:47:12Z","file_id":"5894","creator":"dernst","relation":"main_file","file_name":"2019_Annales_Moser.pdf"}],"external_id":{"isi":["000462444300008"],"arxiv":["1807.00739"]},"publication_status":"published","issue":"4","_id":"5856","publisher":"Springer","department":[{"_id":"RoSe"}],"article_type":"original","publication_identifier":{"issn":["14240637"]},"isi":1,"project":[{"grant_number":"694227","_id":"25C6DC12-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"Analysis of quantum many-body systems"},{"call_identifier":"FWF","name":"Structure of the Excitation Spectrum for Many-Body Quantum Systems","_id":"25C878CE-B435-11E9-9278-68D0E5697425","grant_number":"P27533_N27"},{"name":"IST Austria Open Access Fund","_id":"B67AFEDC-15C9-11EA-A837-991A96BB2854"}],"year":"2019","month":"04","related_material":{"record":[{"relation":"dissertation_contains","status":"public","id":"52"}]},"abstract":[{"text":"We give a bound on the ground-state energy of a system of N non-interacting fermions in a three-dimensional cubic box interacting with an impurity particle via point interactions.

However, in settings where such failure can happen with substantial probability, one needs to provide guarantees even for the bad case. A typical example is where a (possibly weak) password is used instead of a secure cryptographic key to protect a session, the bad event being that the adversary correctly guesses the password. In a situation with multiple such sessions, a per-session guarantee is desired: any session for which the password has not been guessed remains secure, independently of whether other sessions have been compromised. A new formalism for stating such gracefully degrading security guarantees is introduced and applied to analyze the examples of password-based message authentication and password-based encryption. While a natural per-message guarantee is achieved for authentication, the situation of password-based encryption is more delicate: a per-session confidentiality guarantee only holds against attackers for which the distribution of password-guessing effort over the sessions is known in advance. In contrast, for more general attackers without such a restriction, a strong, composable notion of security cannot be achieved."}],"language":[{"iso":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2021-01-12T08:05:08Z","status":"public","author":[{"first_name":"Gregory","last_name":"Demay","full_name":"Demay, Gregory"},{"first_name":"Peter","id":"3E0BFE38-F248-11E8-B48F-1D18A9856A87","full_name":"Gazi, Peter","last_name":"Gazi"},{"full_name":"Maurer, Ueli","last_name":"Maurer","first_name":"Ueli"},{"full_name":"Tackmann, Bjorn","last_name":"Tackmann","first_name":"Bjorn"}],"publication_status":"published","issue":"1","_id":"5887","oa_version":"Preprint","type":"journal_article","publisher":"IOS Press","article_type":"original","department":[{"_id":"KrPi"}],"project":[{"grant_number":"682815","name":"Teaching Old Crypto New Tricks","call_identifier":"H2020","_id":"258AA5B2-B435-11E9-9278-68D0E5697425"}],"month":"01","year":"2019","publication_identifier":{"issn":["0926227X"]}},{"citation":{"mla":"Goremykina, Anna, et al. “Analytically Solvable Renormalization Group for the Many-Body Localization Transition.” <i>Physical Review Letters</i>, vol. 122, no. 4, 040601, American Physical Society, 2019, doi:<a href=\"https://doi.org/10.1103/physrevlett.122.040601\">10.1103/physrevlett.122.040601</a>.","chicago":"Goremykina, Anna, Romain Vasseur, and Maksym Serbyn. “Analytically Solvable Renormalization Group for the Many-Body Localization Transition.” <i>Physical Review Letters</i>.

Our approach relies on a family of RG flows parametrized by the asymmetry between thermal and localized phases. We identify the physical MBL transition in the limit of maximal asymmetry, reflecting the instability of MBL against rare thermal inclusions. We find a critical point that is localized with power-law distributed thermal inclusions. The typical size of critical inclusions remains finite at the transition, while the average size is logarithmically diverging. We propose a two-parameter scaling theory for the many-body localization transition that falls into the Kosterlitz-Thouless universality class, with the MBL phase corresponding to a stable line of fixed points with multifractal behavior.","lang":"eng"}],"scopus_import":"1","date_updated":"2024-02-28T13:13:38Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"status":"public","author":[{"last_name":"Goremykina","full_name":"Goremykina, Anna","first_name":"Anna"},{"first_name":"Romain","last_name":"Vasseur","full_name":"Vasseur, Romain"},{"id":"47809E7E-F248-11E8-B48F-1D18A9856A87","first_name":"Maksym","orcid":"0000-0002-2399-5827","last_name":"Serbyn","full_name":"Serbyn, Maksym"}]},{"department":[{"_id":"FlSc"}],"month":"01","year":"2019","isi":1,"issue":"1","_id":"5907","publication_status":"published","external_id":{"isi":["000456392400012"]},"ddc":["580"],"oa_version":"Published Version","file":[{"relation":"main_file","creator":"dernst","file_id":"5923","file_name":"2019_ScientificReports_Mocsai.pdf","date_created":"2019-02-05T13:10:02Z","checksum":"4129c7d7663d1f8a1edf8c4232372f66","file_size":2124292,"date_updated":"2020-07-14T12:47:13Z","content_type":"application/pdf","access_level":"open_access"}],"type":"journal_article","publisher":"Nature Publishing Group","author":[{"last_name":"Mócsai","full_name":"Mócsai, Réka","first_name":"Réka"},{"first_name":"Rudolf","full_name":"Figl, Rudolf","last_name":"Figl"},{"first_name":"Clemens","last_name":"Troschl","full_name":"Troschl, Clemens"},{"last_name":"Strasser","full_name":"Strasser, Richard","first_name":"Richard"},{"last_name":"Svehla","full_name":"Svehla, Elisabeth","first_name":"Elisabeth"},{"first_name":"Markus","full_name":"Windwarder, Markus","last_name":"Windwarder"},{"full_name":"Thader, Andreas","last_name":"Thader","first_name":"Andreas","id":"3A18A7B8-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Friedrich","full_name":"Altmann, Friedrich","last_name":"Altmann"}],"status":"public","scopus_import":"1","abstract":[{"text":"Microalgae of the genus Chlorella vulgaris are candidates for the production of lipids for biofuel production. Besides that, Chlorella vulgaris is marketed as protein and vitamin rich food additive. Its potential as a novel expression system for recombinant proteins inspired us to study its asparagine-linked oligosaccharides (N-glycans) by mass spectrometry, chromatography and gas chromatography. Oligomannosidic N-glycans with up to nine mannoses were the structures found in culture collection strains as well as several commercial products. These glycans co-eluted with plant N-glycans in the highly shape selective porous graphitic carbon chromatography. Thus, Chlorella vulgaris generates oligomannosidic N-glycans of the structural type known from land plants and animals. In fact, Man5 (Man5GlcNAc2) served as substrate for GlcNAc-transferase I and a trace of an endogenous structure with terminal GlcNAc was seen. The unusual more linear Man5 structure recently found on glycoproteins of Chlamydomonas reinhardtii occurred - if at all - in traces only. Notably, a majority of the oligomannosidic glycans was multiply O-methylated with 3-O-methyl and 3,6-di-O-methyl mannoses at the non-reducing termini. This modification has so far been neither found on plant nor vertebrate N-glycans. It’s possible immunogenicity raises concerns as to the use of C. vulgaris for production of pharmaceutical glycoproteins.","lang":"eng"}],"language":[{"iso":"eng"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","date_updated":"2023-08-24T14:33:16Z","title":"N-glycans of the microalga Chlorella vulgaris are of the oligomannosidic type but highly methylated","quality_controlled":"1","citation":{"apa":"Mócsai, R., Figl, R., Troschl, C., Strasser, R., Svehla, E., Windwarder, M., … Altmann, F.

MCS connections enable the nonvesicular exchange of information between organelles and allow them to coordinate responses to changing cellular environments. In plants, the importance of MCS components in the responses to environmental stress has been widely established, but the molecular mechanisms regulating interorganelle connectivity during stress still remain opaque. In this report, we use the model plant Arabidopsis thaliana to show that ionic stress increases endoplasmic reticulum (ER)–plasma membrane (PM) connectivity by promoting the cortical expansion of synaptotagmin 1 (SYT1)-enriched ER–PM contact sites (S-EPCSs). We define differential roles for the cortical cytoskeleton in the regulation of S-EPCS dynamics and ER–PM connectivity, and we identify the accumulation of phosphatidylinositol 4,5-bisphosphate [PI(4,5)P2] at the PM as a molecular signal associated with the ER–PM connectivity changes. Our study highlights the functional conservation of EPCS components and PM phosphoinositides as modulators of ER–PM connectivity in eukaryotes, and uncovers unique aspects of the spatiotemporal regulation of ER–PM connectivity in plants.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1073/pnas.1818099116"}],"scopus_import":"1","author":[{"first_name":"Eunkyoung","last_name":"Lee","full_name":"Lee, Eunkyoung"},{"first_name":"Steffen","last_name":"Vanneste","full_name":"Vanneste, Steffen"},{"first_name":"Jessica","last_name":"Pérez-Sancho","full_name":"Pérez-Sancho, Jessica"},{"first_name":"Francisco","last_name":"Benitez-Fuente","full_name":"Benitez-Fuente, Francisco"},{"first_name":"Matthew","last_name":"Strelau","full_name":"Strelau, Matthew"},{"full_name":"Macho, Alberto P.","last_name":"Macho","first_name":"Alberto P."},{"first_name":"Miguel A.","last_name":"Botella","full_name":"Botella, Miguel A."},{"last_name":"Friml","full_name":"Friml, Jiří","orcid":"0000-0002-8302-7596","first_name":"Jiří","id":"4159519E-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Abel","full_name":"Rosado, Abel","last_name":"Rosado"}],"status":"public"},{"language":[{"iso":"eng"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","date_updated":"2023-08-24T14:29:48Z","scopus_import":"1","abstract":[{"lang":"eng","text":"Empirical data suggest that inversions in many species contain genes important for intraspecific divergence and speciation, yet mechanisms of evolution remain unclear.

Inversion polymorphisms are maintained by different processes, for example, divergent or balancing selection, or a mix of multiple processes. Moreover, the relative roles of selection, drift, mutation, and recombination will change over the lifetime of an inversion and within its area of distribution.

From spectral analysis we characterize the Strouhal number and amplitude of the hairpin instability as a function of R and ReD. We demonstrate that the dynamics of the hairpins is well described by the Landau model, and, hence, that the instability occurs through Hopf bifurcation, similarly to other hydrodynamical oscillators such as wake behind different bluff bodies. Using the Landau model, we determine the precise threshold values of hairpin shedding. We also study the spatial dependence of this hydrodynamical instability, which shows a global behaviour."}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","language":[{"iso":"eng"}],"date_updated":"2023-08-24T14:43:13Z","article_type":"original","department":[{"_id":"BjHo"}],"project":[{"name":"ISTplus - Postdoctoral Fellowships","call_identifier":"H2020","_id":"260C2330-B435-11E9-9278-68D0E5697425","grant_number":"754411"}],"month":"03","year":"2019","isi":1,"publication_status":"published","external_id":{"arxiv":["1902.07931"],"isi":["000526029100016"]},"_id":"5943","type":"journal_article","oa_version":"Preprint","publisher":"Cambridge University Press","article_processing_charge":"No","ec_funded":1,"doi":"10.1017/jfm.2018.974","date_published":"2019-03-25T00:00:00Z","intvolume":"       863","publication":"Journal of Fluid Mechanics","day":"25","volume":863,"title":"Experiments on a jet in a crossflow in the low-velocity-ratio regime","page":"386-406","arxiv":1,"quality_controlled":"1","date_created":"2019-02-10T22:59:15Z","citation":{"mla":"Klotz, Lukasz, et al. “Experiments on a Jet in a Crossflow in the Low-Velocity-Ratio Regime.” <i>Journal of Fluid Mechanics</i>, vol. 863, Cambridge University Press, 2019, pp. 386–406, doi:<a href=\"https://doi.org/10.1017/jfm.2018.974\">10.1017/jfm.2018.974</a>.","apa":"Klotz, L., Gumowski, K., &#38; Wesfreid, J.
