Each αi and each βj is either an arc meeting the boundary of ℳ at its two endpoints, or a closed curve. The αi are pairwise disjoint except for possibly sharing endpoints, and similarly for the βj. We want to &quot;untangle&quot; the βj from the αi by a self-homeomorphism of ℳ; more precisely, we seek an homeomorphism φ: ℳ → ℳ fixing the boundary of ℳ pointwise such that the total number of crossings of the αi with the φ(βj) is as small as possible. This problem is motivated by an application in the algorithmic theory of embeddings and 3-manifolds. We prove that if ℳ is planar, i.e., a sphere with h ≥ 0 boundary components (&quot;holes&quot;), then O(mn) crossings can be achieved (independently of h), which is asymptotically tight, as an easy lower bound shows. In general, for an arbitrary (orientable or nonorientable) surface ℳ with h holes and of (orientable or nonorientable) genus g ≥ 0, we obtain an O((m + n)4) upper bound, again independent of h and g.

The verifier is able to recover m from τ and at the same time verify its authenticity. The two most important parameters of such a scheme are its security and overhead |τ| − |m|. A simple argument shows that for any scheme with “n bits security” |τ| − |m| ≥ n, i.e., the overhead is lower bounded by the security parameter n. Currently, the best known constructions in the random oracle model are far from this lower bound requiring an overhead of n + logq h , where q h is the number of queries to the random oracle. In this paper we give a construction which basically matches the n bit lower bound. We propose a simple digital signature scheme with n + o(logq h ) bits overhead, where q h denotes the number of random oracle queries.\r\n\r\nOur construction works in two steps. First, we propose a signature scheme with message recovery having optimal overhead in a new ideal model, the random invertible function model. Second, we show that a four-round Feistel network with random oracles as round functions is tightly “public-indifferentiable” from a random invertible function. At the core of our indifferentiability proof is an almost tight upper bound for the expected number of edges of the densest “small” subgraph of a random Cayley graph, which may be of independent interest.\r\n","lang":"eng"}],"quality_controlled":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"Springer","intvolume":"      8042","ec_funded":1,"day":"01","title":"Digital signatures with minimal overhead from indifferentiable random invertible functions","_id":"2258","ddc":["000","004"],"department":[{"_id":"KrPi"}],"date_published":"2013-01-01T00:00:00Z","alternative_title":["LNCS"],"type":"conference","status":"public"},{"date_published":"2013-01-01T00:00:00Z","alternative_title":["LNCS"],"type":"conference","status":"public","day":"01","title":"Learning with rounding, revisited: New reduction properties and applications","ec_funded":1,"intvolume":"      8042","_id":"2259","ddc":["000","004"],"department":[{"_id":"KrPi"}],"pubrep_id":"684","abstract":[{"lang":"eng","text":"The learning with rounding (LWR) problem, introduced by Banerjee, Peikert and Rosen at EUROCRYPT ’12, is a variant of learning with errors (LWE), where one replaces random errors with deterministic rounding. 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"}],"publisher":"Springer","quality_controlled":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"has_accepted_license":"1","oa_version":"Published Version","doi":"10.1007/978-3-642-40041-4_4","year":"2013","series_title":"Lecture Notes in Computer Science","citation":{"apa":"Alwen, J.

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."}],"publisher":"Company of Biologists","quality_controlled":"1","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","publication_status":"published","external_id":{"isi":["000313363500009"],"pmid":["23293287"]},"publist_id":"4681","language":[{"iso":"eng"}],"year":"2013","publication":"Development","citation":{"apa":"Liang, H., Xiao, G., Yin, H., Hippenmeyer, S., Horowitz, J., &#38; Ghashghaei, T.

There is an inher-\r\nent tradeoff between how general a language is, allowing it to  capture  more  elaborate  games,  and  how  hard  it  is  computationally to optimize and solve such games.  One prominent  such  language  is  the  simple  yet  expressive\r\nWeighted Graph Games  (WGGs) representation (Deng  and Papadimitriou 1994), which maintains knowledge about synergies between agents in the form of an edge weighted graph. We  consider  the  problem  of  finding  the  optimal  coalition structure in WGGs. The agents in such games are vertices in a graph, and the value of a coalition is the sum of the weights of the edges present between coalition members. The optimal coalition structure is a partition of the agents to coalitions, that maximizes the sum of utilities obtained by the coalitions. We  show  that  finding  the  optimal  coalition  structure  is  not only hard for general graphs,  but is also intractable for restricted families such as planar graphs which are amenable for many other combinatorial problems.  We then provide algorithms with constant factor approximations for planar, minorfree and bounded degree graphs.","lang":"eng"}],"page":"81-87","publisher":"AAAI Press","author":[{"full_name":"Bachrach, Yoram","first_name":"Yoram","last_name":"Bachrach"},{"last_name":"Kohli","first_name":"Pushmeet","full_name":"Kohli, Pushmeet"},{"first_name":"Vladimir","id":"3D50B0BA-F248-11E8-B48F-1D18A9856A87","last_name":"Kolmogorov","full_name":"Kolmogorov, Vladimir"},{"first_name":"Morteza","last_name":"Zadimoghaddam","full_name":"Zadimoghaddam, Morteza"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","arxiv":1,"quality_controlled":"1"},{"publist_id":"4672","external_id":{"isi":["000381149500002"]},"publication_status":"published","language":[{"iso":"eng"}],"publication":"ICML'13 Proceedings of the 30th International Conference on International","related_material":{"record":[{"relation":"later_version","id":"1794","status":"public"}]},"year":"2013","citation":{"mla":"Takhanov, Rustem, and Vladimir Kolmogorov. “Inference Algorithms for Pattern-Based CRFs on Sequence Data.” <i>ICML’13 Proceedings of the 30th International Conference on International</i>, vol. 28, no. 3, ML Research Press, 2013, pp. 145–53.","ieee":"R.

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).

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."}],"doi":"10.1371/journal.pcbi.1003344","oa_version":"Published Version","has_accepted_license":"1","oa":1,"article_number":"e1003344"},{"date_updated":"2025-09-29T14:26:53Z","month":"11","isi":1,"page":"4873 - 4884","author":[{"first_name":"Raquel","last_name":"Pérez Gómez","full_name":"Pérez Gómez, Raquel"},{"first_name":"Jana","id":"30F3F2F0-F248-11E8-B48F-1D18A9856A87","last_name":"Slovakova","full_name":"Slovakova, Jana"},{"full_name":"Rives Quinto, Noemí","first_name":"Noemí","last_name":"Rives Quinto"},{"full_name":"Krejčí, Alena","first_name":"Alena","last_name":"Krejčí"},{"first_name":"Ana","last_name":"Carmena","full_name":"Carmena, Ana"}],"scopus_import":"1","issue":"21","date_created":"2018-12-11T11:56:43Z","volume":126,"language":[{"iso":"eng"}],"publication_status":"published","publist_id":"4658","external_id":{"isi":["000326392500009"]},"citation":{"short":"R.

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."}],"_id":"2278","department":[{"_id":"CaHe"}],"day":"01","title":"A serrate-notch-canoe complex mediates essential interactions between glia and neuroepithelial cells during Drosophila optic lobe development","intvolume":"       126","status":"public","article_processing_charge":"No","date_published":"2013-11-01T00:00:00Z","type":"journal_article"},{"author":[{"last_name":"Chatterjee","orcid":"0000-0002-4561-241X","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","first_name":"Krishnendu","full_name":"Chatterjee, Krishnendu"},{"first_name":"Laurent","last_name":"Doyen","full_name":"Doyen, Laurent"},{"last_name":"Randour","first_name":"Mickael","full_name":"Randour, Mickael"},{"full_name":"Raskin, Jean","last_name":"Raskin","first_name":"Jean"}],"page":"118 - 132","volume":8172,"date_created":"2018-12-11T11:56:44Z","scopus_import":"1","project":[{"grant_number":"279307","_id":"2581B60A-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","name":"Quantitative Graph Games: Theory and Applications"}],"month":"01","date_updated":"2025-09-23T09:29:54Z","conference":{"name":"ATVA: Automated Technology for Verification and Analysis","location":"Hanoi, Vietnam","end_date":"2013-10-18","start_date":"2013-10-15"},"citation":{"short":"K.

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."}],"corr_author":"1","publisher":"Nature Publishing Group","quality_controlled":"1","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","oa":1,"main_file_link":[{"open_access":"1","url":"http://hal.upmc.fr/hal-00983313/"}],"oa_version":"Submitted Version","doi":"10.1038/ncb2869","date_published":"2013-11-10T00:00:00Z","type":"journal_article","status":"public","article_processing_charge":"No","day":"10","title":"Tension-oriented cell divisions limit anisotropic tissue tension in epithelial spreading during zebrafish epiboly","intvolume":"        15","acknowledgement":"This work was supported by the IST Austria and MPI-CBG ","_id":"2282","department":[{"_id":"CaHe"}],"scopus_import":"1","project":[{"grant_number":"I930-B20","call_identifier":"FWF","_id":"252ABD0A-B435-11E9-9278-68D0E5697425","name":"Control of Epithelial Cell Layer Spreading in Zebrafish"}],"date_created":"2018-12-11T11:56:45Z","volume":15,"page":"1405 - 1414","author":[{"id":"3AFBBC42-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8526-5416","first_name":"Pedro","last_name":"Campinho","full_name":"Campinho, Pedro"},{"full_name":"Behrndt, Martin","last_name":"Behrndt","first_name":"Martin","id":"3ECECA3A-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Ranft, Jonas","first_name":"Jonas","last_name":"Ranft"},{"last_name":"Risler","first_name":"Thomas","full_name":"Risler, Thomas"},{"last_name":"Minc","first_name":"Nicolas","full_name":"Minc, Nicolas"},{"last_name":"Heisenberg","id":"39427864-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-0912-4566","first_name":"Carl-Philipp J","full_name":"Heisenberg, Carl-Philipp J"}],"date_updated":"2026-03-09T14:56:18Z","month":"11","isi":1,"year":"2013","publication":"Nature Cell Biology","related_material":{"record":[{"status":"public","id":"1403","relation":"dissertation_contains"}]},"citation":{"short":"P.

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."}],"doi":"10.1007/s00114-013-1115-5","oa_version":"None","article_processing_charge":"No","status":"public","type":"journal_article","date_published":"2013-11-14T00:00:00Z","department":[{"_id":"SyCr"}],"_id":"2283","intvolume":"       100","title":"Tolerating an infection: an indirect benefit of co-founding queen associations in the ant Lasius niger ","day":"14"},{"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"year":"2013","related_material":{"record":[{"status":"public","id":"9753","relation":"research_data"}]},"publication":"BMC Evolutionary Biology","citation":{"apa":"Tragust, S., Ugelvig, L.

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"}],"pubrep_id":"402","publisher":"BioMed Central","corr_author":"1","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","quality_controlled":"1","article_number":"225","oa":1,"has_accepted_license":"1","oa_version":"Published Version","doi":"10.1186/1471-2148-13-225"},{"doi":"10.1038/emboj.2013.225","main_file_link":[{"url":"http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3817470/","open_access":"1"}],"oa_version":"Submitted Version","oa":1,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","quality_controlled":"1","corr_author":"1","publisher":"Wiley-Blackwell","abstract":[{"lang":"eng","text":"The spatiotemporal control of cell divisions is a key factor in epithelial morphogenesis and patterning.
