The LWR problem was shown to be as hard as LWE for a setting of parameters where the modulus and modulus-to-error ratio are super-polynomial. In this work we resolve the main open problem and give a new reduction that works for a larger range of parameters, allowing for a polynomial modulus and modulus-to-error ratio. In particular, a smaller modulus gives us greater efficiency, and a smaller modulus-to-error ratio gives us greater security, which now follows from the worst-case hardness of GapSVP with polynomial (rather than super-polynomial) approximation factors.\r\n\r\nAs a tool in the reduction, we show that there is a “lossy mode” for the LWR problem, in which LWR samples only reveal partial information about the secret. This property gives us several interesting new applications, including a proof that LWR remains secure with weakly random secrets of sufficient min-entropy, and very simple constructions of deterministic encryption, lossy trapdoor functions and reusable extractors.\r\n\r\nOur approach is inspired by a technique of Goldwasser et al. from ICS ’10, which implicitly showed the existence of a “lossy mode” for LWE. By refining this technique, we also improve on the parameters of that work to only requiring a polynomial (instead of super-polynomial) modulus and modulus-to-error ratio.\r\n","lang":"eng"}],"status":"public","author":[{"full_name":"Alwen, Joel F","last_name":"Alwen","id":"2A8DFA8C-F248-11E8-B48F-1D18A9856A87","first_name":"Joel F"},{"orcid":"0000-0003-2835-9093","last_name":"Krenn","full_name":"Krenn, Stephan","id":"329FCCF0-F248-11E8-B48F-1D18A9856A87","first_name":"Stephan"},{"id":"3E04A7AA-F248-11E8-B48F-1D18A9856A87","first_name":"Krzysztof Z","orcid":"0000-0002-9139-1654","last_name":"Pietrzak","full_name":"Pietrzak, Krzysztof Z"},{"first_name":"Daniel","last_name":"Wichs","full_name":"Wichs, Daniel"}],"publisher":"Springer","pubrep_id":"684","alternative_title":["LNCS"],"publication_status":"published","issue":"1","_id":"2259","oa_version":"Published Version","file":[{"relation":"main_file","file_id":"4912","creator":"system","file_name":"IST-2016-684-v1+1_098.pdf","date_created":"2018-12-12T10:11:55Z","checksum":"16d428408a806b8e49eecc607deab115","file_size":587898,"date_updated":"2020-07-14T12:45:35Z","access_level":"open_access","content_type":"application/pdf"}],"type":"conference","ddc":["000","004"],"project":[{"grant_number":"259668","name":"Provable Security for Physical Cryptography","call_identifier":"FP7","_id":"258C570E-B435-11E9-9278-68D0E5697425"}],"month":"01","year":"2013","department":[{"_id":"KrPi"}],"day":"01","volume":8042,"date_published":"2013-01-01T00:00:00Z","has_accepted_license":"1","intvolume":"      8042","file_date_updated":"2020-07-14T12:45:35Z","doi":"10.1007/978-3-642-40041-4_4","ec_funded":1,"oa":1,"quality_controlled":"1","conference":{"name":"CRYPTO: International Cryptology Conference","start_date":"2013-08-18","location":"Santa Barbara, CA, United States","end_date":"2013-08-22"},"citation":{"mla":"Alwen, Joel F., et al. <i>Learning with Rounding, Revisited: New Reduction Properties and Applications</i>.

Here, we demonstrate that neural stem cells (NSCs) and intermediate neural progenitor cells (NPCs) employ a zinc-finger transcription factor specificity protein 2 (Sp2) as a cell cycle regulator in two temporally and spatially distinct progenitor domains. Differential conditional deletion of Sp2 in early embryonic cerebral cortical progenitors, and perinatal olfactory bulb progenitors disrupted transitions through G1, G2 and M phases, whereas DNA synthesis appeared intact. Cell-autonomous function of Sp2 was identified by deletion of Sp2 using mosaic analysis with double markers, which clearly established that conditional Sp2-null NSCs and NPCs are M phase arrested in vivo. Importantly, conditional deletion of Sp2 led to a decline in the generation of NPCs and neurons in the developing and postnatal brains. Our findings implicate Sp2-dependent mechanisms as novel regulators of cell cycle progression, the absence of which disrupts neurogenesis in the embryonic and postnatal brain."}],"main_file_link":[{"url":"http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3561788/","open_access":"1"}],"scopus_import":1,"author":[{"first_name":"Huixuan","full_name":"Liang, Huixuan","last_name":"Liang"},{"last_name":"Xiao","full_name":"Xiao, Guanxi","first_name":"Guanxi"},{"first_name":"Haifeng","last_name":"Yin","full_name":"Yin, Haifeng"},{"full_name":"Hippenmeyer, Simon","last_name":"Hippenmeyer","orcid":"0000-0003-2279-1061","id":"37B36620-F248-11E8-B48F-1D18A9856A87","first_name":"Simon"},{"first_name":"Jonathan","last_name":"Horowitz","full_name":"Horowitz, Jonathan"},{"first_name":"Troy","last_name":"Ghashghaei","full_name":"Ghashghaei, Troy"}],"status":"public","oa":1,"citation":{"ista":"Liang H, Xiao G, Yin H, Hippenmeyer S, Horowitz J, Ghashghaei T. 2013.

One way to tackle this NP-hard problem was proposed by Kovtun [19, 20]. It identifies a part of an optimal solution by running k maxflow computations, where k is the number of labels. The number of “labeled” pixels can be significant in some applications, e.g. 50-93% in our tests for stereo. We show how to reduce the runtime to O (log k) maxflow computations (or one parametric maxflow computation). Furthermore, the output of our algorithm allows to speed-up the subsequent alpha expansion for the unlabeled part, or can be used as it is for time-critical applications. To derive our technique, we generalize the algorithm of Felzenszwalb et al. [7] for Tree Metrics . We also show a connection to k-submodular functions from combinatorial optimization, and discuss k-submodular relaxations for general energy functions."}],"language":[{"iso":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"01","date_updated":"2021-01-12T06:56:28Z","status":"public","author":[{"last_name":"Gridchyn","full_name":"Gridchyn, Igor","id":"4B60654C-F248-11E8-B48F-1D18A9856A87","first_name":"Igor"},{"id":"3D50B0BA-F248-11E8-B48F-1D18A9856A87","first_name":"Vladimir","last_name":"Kolmogorov","full_name":"Kolmogorov, Vladimir"}],"doi":"10.1109/ICCV.2013.288"},{"oa_version":"Published Version","type":"journal_article","ddc":["570"],"file":[{"file_name":"IST-2016-410-v1+1_journal.pcbi.1003344.pdf","relation":"main_file","file_id":"5089","creator":"system","date_updated":"2020-07-14T12:45:36Z","access_level":"open_access","content_type":"application/pdf","date_created":"2018-12-12T10:14:36Z","checksum":"46722afc4f7eabb0831165d9c1b171ad","file_size":3115568}],"publication_status":"published","_id":"2277","issue":"12","publisher":"Public Library of Science","pubrep_id":"410","department":[{"_id":"GaTk"}],"year":"2013","month":"12","related_material":{"record":[{"id":"9752","status":"public","relation":"research_data"}]},"abstract":[{"lang":"eng","text":"Redundancies and correlations in the responses of sensory neurons may seem to waste neural resources, but they can also carry cues about structured stimuli and may help the brain to correct for response errors. To investigate the effect of stimulus structure on redundancy in retina, we measured simultaneous responses from populations of retinal ganglion cells presented with natural and artificial stimuli that varied greatly in correlation structure; these stimuli and recordings are publicly available online. Responding to spatio-temporally structured stimuli such as natural movies, pairs of ganglion cells were modestly more correlated than in response to white noise checkerboards, but they were much less correlated than predicted by a non-adapting functional model of retinal response. Meanwhile, responding to stimuli with purely spatial correlations, pairs of ganglion cells showed increased correlations consistent with a static, non-adapting receptive field and nonlinearity. We found that in response to spatio-temporally correlated stimuli, ganglion cells had faster temporal kernels and tended to have stronger surrounds. These properties of individual cells, along with gain changes that opposed changes in effective contrast at the ganglion cell input, largely explained the pattern of pairwise correlations across stimuli where receptive field measurements were possible."}],"scopus_import":1,"date_updated":"2023-02-23T14:07:04Z","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"status":"public","author":[{"first_name":"Kristina","full_name":"Simmons, Kristina","last_name":"Simmons"},{"last_name":"Prentice","full_name":"Prentice, Jason","first_name":"Jason"},{"first_name":"Gasper","id":"3D494DCA-F248-11E8-B48F-1D18A9856A87","full_name":"Tkacik, Gasper","last_name":"Tkacik","orcid":"0000-0002-6699-1455"},{"full_name":"Homann, Jan","last_name":"Homann","first_name":"Jan"},{"full_name":"Yee, Heather","last_name":"Yee","first_name":"Heather"},{"full_name":"Palmer, Stephanie","last_name":"Palmer","first_name":"Stephanie"},{"first_name":"Philip","last_name":"Nelson","full_name":"Nelson, Philip"},{"first_name":"Vijay","last_name":"Balasubramanian","full_name":"Balasubramanian, Vijay"}],"citation":{"ista":"Simmons K, Prentice J, Tkačik G, Homann J, Yee H, Palmer S, Nelson P, Balasubramanian V. 2013.

Here, we found that the glia of the Drosophila larval brain display an essential non-autonomous role during the development of the optic lobe. The optic lobe develops from neuroepithelial cells that proliferate by dividing symmetrically until they switch to asymmetric/differentiative divisions that generate neuroblasts. The proneural gene lethal of scute (l9sc) is transiently activated by the epidermal growth factor receptor (EGFR)-Ras signal transduction pathway at the leading edge of a proneural wave that sweeps from medial to lateral neuroepithelium, promoting this switch. This process is tightly regulated by the tissue-autonomous function within the neuroepithelium of multiple signaling pathways, including EGFR-Ras and Notch. This study shows that the Notch ligand Serrate (Ser) is expressed in the glia and it forms a complex in vivo with Notch and Canoe, which colocalize at the adherens junctions of neuroepithelial cells. This complex is crucial for interactions between glia and neuroepithelial cells during optic lobe development. Ser is tissue-autonomously required in the glia where it activates Notch to regulate its proliferation, and non-autonomously in the neuroepithelium where Ser induces Notch signaling to avoid the premature activation of the EGFR-Ras pathway and hence of L9sc. Interestingly, different Notch activity reporters showed very different expression patterns in the glia and in the neuroepithelium, suggesting the existence of tissue-specific factors that promote the expression of particular Notch target genes or/and a reporter response dependent on different thresholds of Notch signaling."}],"scopus_import":1,"date_published":"2013-11-01T00:00:00Z","doi":"10.1242/jcs.125617","status":"public","author":[{"last_name":"Pérez Gómez","full_name":"Pérez Gómez, Raquel","first_name":"Raquel"},{"id":"30F3F2F0-F248-11E8-B48F-1D18A9856A87","first_name":"Jana","full_name":"Slovakova, Jana","last_name":"Slovakova"},{"first_name":"Noemí","last_name":"Rives Quinto","full_name":"Rives Quinto, Noemí"},{"full_name":"Krejčí, Alena","last_name":"Krejčí","first_name":"Alena"},{"first_name":"Ana","last_name":"Carmena","full_name":"Carmena, Ana"}]},{"citation":{"mla":"Chatterjee, Krishnendu, et al. <i>Looking at Mean-Payoff and Total-Payoff through Windows</i>.

A key challenge for epithelial tissues undergoing spreading is to increase their surface area without disrupting epithelial integrity. Here we show that orienting cell divisions by tension constitutes an efficient mechanism by which the enveloping cell layer (EVL) releases anisotropic tension while undergoing spreading during zebrafish epiboly. The control of EVL cell-division orientation by tension involves cell elongation and requires myosin II activity to align the mitotic spindle with the main tension axis. We also found that in the absence of tension-oriented cell divisions and in the presence of increased tissue tension, EVL cells undergo ectopic fusions, suggesting that the reduction of tension anisotropy by oriented cell divisions is required to prevent EVL cells from fusing. We conclude that cell-division orientation by tension constitutes a key mechanism for limiting tension anisotropy and thus promoting tissue spreading during EVL epiboly."}],"related_material":{"record":[{"relation":"dissertation_contains","status":"public","id":"1403"}]},"main_file_link":[{"url":"http://hal.upmc.fr/hal-00983313/","open_access":"1"}],"scopus_import":1,"author":[{"orcid":"0000-0002-8526-5416","last_name":"Campinho","full_name":"Campinho, Pedro","first_name":"Pedro","id":"3AFBBC42-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Behrndt","full_name":"Behrndt, Martin","first_name":"Martin","id":"3ECECA3A-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Ranft","full_name":"Ranft, Jonas","first_name":"Jonas"},{"first_name":"Thomas","last_name":"Risler","full_name":"Risler, Thomas"},{"last_name":"Minc","full_name":"Minc, Nicolas","first_name":"Nicolas"},{"orcid":"0000-0002-0912-4566","full_name":"Heisenberg, Carl-Philipp J","last_name":"Heisenberg","first_name":"Carl-Philipp J","id":"39427864-F248-11E8-B48F-1D18A9856A87"}],"status":"public","oa":1,"acknowledged_ssus":[{"_id":"PreCl"},{"_id":"Bio"}],"citation":{"chicago":"Campinho, Pedro, Martin Behrndt, Jonas Ranft, Thomas Risler, Nicolas Minc, and Carl-Philipp J Heisenberg. “Tension-Oriented Cell Divisions Limit Anisotropic Tissue Tension in Epithelial Spreading during Zebrafish Epiboly.” <i>Nature Cell Biology</i>.

In addition to individual immunity, social organisms can act cooperatively to produce collective defences. In many ant species, queens have the option to found a colony alone or in groups with other, often unrelated, conspecifics. These associations are transient, usually lasting only as long as each queen benefits from the presence of others. In fact, once the first workers emerge, queens fight to the death for dominance. One potential advantage of co-founding may be that queens benefit from collective disease defences, such as mutual grooming, that act against common soil pathogens. We test this hypothesis by exposing single and co-founding queens to a fungal parasite, in order to assess whether queens in co-founding associations have improved survival. Surprisingly, co-foundresses exposed to the entomopathogenic fungus Metarhizium did not engage in cooperative disease defences, and consequently, we find no direct benefit of multiple queens on survival. However, an indirect benefit was observed, with parasite-exposed queens producing more brood when they co-founded, than when they were alone. We suggest this is due to a trade-off between reproduction and immunity. Additionally, we report an extraordinary ability of the queens to tolerate an infection for long periods after parasite exposure. Our study suggests that there are no social immunity benefits for co-founding ant queens, but that in parasite-rich environments, the presence of additional queens may nevertheless improve the chances of colony founding success."}],"date_published":"2013-11-14T00:00:00Z","scopus_import":1,"day":"14","publication":"Naturwissenschaften","date_updated":"2021-01-12T06:56:31Z","volume":100,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"status":"public","author":[{"orcid":"0000-0003-1122-3982","full_name":"Pull, Christopher","last_name":"Pull","first_name":"Christopher","id":"3C7F4840-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Hughes","full_name":"Hughes, William","first_name":"William"},{"first_name":"Markus","id":"3DAB9AFC-F248-11E8-B48F-1D18A9856A87","last_name":"Brown","full_name":"Brown, Markus"}],"doi":"10.1007/s00114-013-1115-5","oa_version":"None","type":"journal_article","date_created":"2018-12-11T11:56:45Z","citation":{"chicago":"Pull, Christopher, William Hughes, and Markus Brown. “Tolerating an Infection: An Indirect Benefit of Co-Founding Queen Associations in the Ant Lasius Niger .” <i>Naturwissenschaften</i>.

We here test whether the presence of a pupal cocoon, which occurs in some ant species but not in others, affects the sanitary brood care and fungal infection patterns after exposure to the entomopathogenic fungus Metarhizium brunneum. We use a) a comparative approach analysing four species with either naked or cocooned pupae and b) a within-species analysis of a single ant species, in which both pupal types co-exist in the same colony. Results: We found that the presence of a cocoon did not compromise fungal pathogen detection by the ants and that species with cocooned pupae increased brood grooming after pathogen exposure. All tested ant species further removed brood from their nests, which was predominantly expressed towards larvae and naked pupae treated with the live fungal pathogen. In contrast, cocooned pupae exposed to live fungus were not removed at higher rates than cocooned pupae exposed to dead fungus or a sham control. Consistent with this, exposure to the live fungus caused high numbers of infections and fungal outgrowth in larvae and naked pupae, but not in cocooned pupae. Moreover, the ants consistently removed the brood prior to fungal outgrowth, ensuring a clean brood chamber. Conclusion: Our study suggests that the pupal cocoon has a protective effect against fungal infection, causing an adaptive change in sanitary behaviours by the ants. It further demonstrates that brood removal-originally described for honeybees as &quot;hygienic behaviour&quot;-is a widespread sanitary behaviour in ants, which likely has important implications on disease dynamics in social insect colonies.","lang":"eng"}],"related_material":{"record":[{"status":"public","relation":"research_data","id":"9753"}]},"scopus_import":1,"date_updated":"2023-02-23T14:07:06Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"title":"Pupal cocoons affect sanitary brood care and limit fungal infections in ant colonies","publist_id":"4647","citation":{"ama":"Tragust S, Ugelvig LV, Chapuisat M, Heinze J, Cremer S.

A variety of ecological and genetic factors can explain biased sex ratios, although the mechanisms involved are not well understood. Most dioecious species are long-lived and/or clonal complicating efforts to identify stages during the life cycle when biases develop. We investigated the demographic correlates of sex-ratio variation in two chromosome races of Rumex hastatulus, an annual, wind-pollinated colonizer of open habitats from the southern USA. We examined sex ratios in 46 populations and evaluated the hypothesis that the proximity of males in the local mating environment, through its influence on gametophytic selection, is the primary cause of female-biased sex ratios. Female-biased sex ratios characterized most populations of R.  hastatulus (mean sex ratio = 0.62), with significant female bias in 89% of populations. Large, high-density populations had the highest proportion of females, whereas smaller, low-density populations had sex ratios closer to equality. Progeny sex ratios were more female biased when males were in closer proximity to females, a result consistent with the gametophytic selection hypothesis. Our results suggest that interactions between demographic and genetic factors are probably the main cause of female-biased sex ratios in R. hastatulus. The annual life cycle of this species may limit the scope for selection against males and may account for the weaker degree of bias in comparison with perennial Rumex species."}],"scopus_import":1,"date_updated":"2021-01-12T06:56:32Z","language":[{"iso":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},{"date_published":"2013-07-01T00:00:00Z","abstract":[{"text":"This book constitutes the proceedings of the 11th International Conference on Computational Methods in Systems Biology, CMSB 2013, held in Klosterneuburg, Austria, in September 2013.

At the basis of formal verification is the logical notion of correctness, which purports to capture whether or not a program behaves as desired. We suggest that the boolean partition of software into correct and incorrect programs falls short of the practical need to assess the behavior of software in a more nuanced fashion against multiple criteria. We therefore propose to introduce quantitative fitness measures for programs, specifically for measuring the function, performance, and robustness of reactive programs such as concurrent processes. This article describes the goals of the ERC Advanced Investigator Project QUAREM. The project aims to build and evaluate a theory of quantitative fitness measures for reactive models. Such a theory must strive to obtain quantitative generalizations of the paradigms that have been success stories in qualitative reactive modeling, such as compositionality, property-preserving abstraction and abstraction refinement, model checking, and synthesis. The theory will be evaluated not only in the context of software and hardware engineering, but also in the context of systems biology. In particular, we will use the quantitative reactive models and fitness measures developed in this project for testing hypotheses about the mechanisms behind data from biological experiments.","lang":"eng"}],"scopus_import":1,"status":"public","author":[{"last_name":"Henzinger","full_name":"Henzinger, Thomas A","orcid":"0000−0002−2985−7724","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","first_name":"Thomas A"}]},{"publisher":"National Academy of Sciences","issue":"40","_id":"2290","publication_status":"published","external_id":{"pmid":["24043780"]},"oa_version":"Submitted Version","type":"journal_article","year":"2013","month":"10","department":[{"_id":"JiFr"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"date_updated":"2021-01-12T06:56:33Z","scopus_import":1,"abstract":[{"lang":"eng","text":"The plant hormone indole-acetic acid (auxin) is essential for many aspects of plant development. Auxin-mediated growth regulation typically involves the establishment of an auxin concentration gradient mediated by polarly localized auxin transporters. The localization of auxin carriers and their amount at the plasma membrane are controlled by membrane trafficking processes such as secretion, endocytosis, and recycling. In contrast to endocytosis or recycling, how the secretory pathway mediates the localization of auxin carriers is not well understood. In this study we have used the differential cell elongation process during apical hook development to elucidate the mechanisms underlying the post-Golgi trafficking of auxin carriers in Arabidopsis. We show that differential cell elongation during apical hook development is defective in Arabidopsis mutant echidna (ech). ECH protein is required for the trans-Golgi network (TGN)-mediated trafficking of the auxin influx carrier AUX1 to the plasma membrane. In contrast, ech mutation only marginally perturbs the trafficking of the highly related auxin influx carrier LIKE-AUX1-3 or the auxin efflux carrier PIN-FORMED-3, both also involved in hook development. Electron tomography reveals that the trafficking defects in ech mutant are associated with the perturbation of secretory vesicle genesis from the TGN. Our results identify differential mechanisms for the post-Golgi trafficking of de novo-synthesized auxin carriers to plasma membrane from the TGN and reveal how trafficking of auxin influx carriers mediates the control of differential cell elongation in apical hook development."}],"main_file_link":[{"open_access":"1","url":"http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3791722/"}],"author":[{"last_name":"Boutté","full_name":"Boutté, Yohann","first_name":"Yohann"},{"first_name":"Kristoffer","last_name":"Jonsson","full_name":"Jonsson, Kristoffer"},{"full_name":"Mcfarlane, Heather","last_name":"Mcfarlane","first_name":"Heather"},{"full_name":"Johnson, Errin","last_name":"Johnson","first_name":"Errin"},{"last_name":"Gendre","full_name":"Gendre, Delphine","first_name":"Delphine"},{"first_name":"Ranjan","full_name":"Swarup, Ranjan","last_name":"Swarup"},{"orcid":"0000-0002-8302-7596","full_name":"Friml, Jirí","last_name":"Friml","first_name":"Jirí","id":"4159519E-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Lacey","last_name":"Samuels","full_name":"Samuels, Lacey"},{"first_name":"Stéphanie","last_name":"Robert","full_name":"Robert, Stéphanie"},{"full_name":"Bhalerao, Rishikesh","last_name":"Bhalerao","first_name":"Rishikesh"}],"status":"public","oa":1,"quality_controlled":"1","citation":{"mla":"Boutté, Yohann, et al. “ECHIDNA Mediated Post Golgi Trafficking of Auxin Carriers for Differential Cell Elongation.” <i>PNAS</i>, vol. 110, no. 40, National Academy of Sciences, 2013, pp. 16259–64, doi:<a href=\"https://doi.org/10.1073/pnas.1309057110\">10.1073/pnas.1309057110</a>.","apa":"Boutté, Y., Jonsson, K., Mcfarlane, H., Johnson, E., Gendre, D., Swarup, R., … Bhalerao, R.
