These conditions on X, Y guarantee that [X, Y] has a natural structure of a finitely generated Abelian group, and the algorithm finds generators and relations for it. We combine several tools and ideas from homotopy theory (such as Postnikov systems, simplicial sets, and obstruction theory) with algorithmic tools from effective algebraic topology (objects with effective homology). We hope that a further extension of the methods developed here will yield an algorithm for computing, in some cases of interest, the ℤ 2-index, which is a quantity playing a prominent role in Borsuk-Ulam style applications of topology in combinatorics and geometry, e.g., in topological lower bounds for the chromatic number of a graph. In a certain range of dimensions, deciding the embeddability of a simplicial complex into ℝ d also amounts to a ℤ 2-index computation. This is the main motivation of our work. We believe that investigating the computational complexity of questions in homotopy theory and similar areas presents a fascinating research area, and we hope that our work may help bridge the cultural gap between algebraic topology and theoretical computer science.","lang":"eng"}],"publist_id":"4466"},{"publication_status":"published","status":"public","title":"A geometric proof of the colored Tverberg theorem","intvolume":" 47","publisher":"Springer","acknowledgement":"We would like to thank Marek Krcál for useful discussions at initial stages of this research.

In particular the spectra of the adjacency matrix and of the Laplacian of random graphs G(n, p) are known quite precisely. We consider generalizations of these matrices to simplicial complexes of higher dimensions and study their eigenvalues for the Linial-Meshulam model X k(n, p) of random k-dimensional simplicial complexes on n vertices. We show that for p = Ω(log n/n), the eigenvalues of both, the higher-dimensional adjacency matrix and the Laplacian, are a.a.s. sharply concentrated around two values. In a second part of the paper, we discuss a possible higherdimensional analogue of the Discrete Cheeger Inequality. This fundamental inequality expresses a close relationship between the eigenvalues of a graph and its combinatorial expansion properties; in particular, spectral expansion (a large eigenvalue gap) implies edge expansion. Recently, a higher-dimensional analogue of edge expansion for simplicial complexes was introduced by Gromov, and independently by Linial, Meshulam and Wallach and by Newman and Rabinovich. It is natural to ask whether there is a higher-dimensional version of Cheeger's inequality. We show that the most straightforward version of a higher-dimensional Cheeger inequality fails: for every k > 1, there is an infinite family of k-dimensional complexes that are spectrally expanding (there is a large eigenvalue gap for the Laplacian) but not combinatorially expanding.","lang":"eng"}]},{"day":"01","month":"07","doi":"10.1105/tpc.112.098152","date_published":"2012-07-01T00:00:00Z","quality_controlled":0,"page":"3074 - 3086","publication":"Plant Cell","citation":{"ama":"Feraru E, Feraru M, Asaoka R, et al.

We identified bex5 (for BFA-visualized exocytic trafficking defective), a novel dominant mutant carrying a missense mutation that disrupts a conserved sequence motif of the small GTPase, RAS GENES FROM RAT BRAINA1b. bex5 displays defects such as enhanced protein accumulation in abnormal BFA compartments, aberrant endosomes, and defective exocytosis and transcytosis.

We intend to provide the reader who might have missed this remarkable event with a glimpse of the recent progress made in this blossoming research field."}],"extern":"1","year":"2012","_id":"2456","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","intvolume":" 139","publisher":"Company of Biologists","status":"public","publication_status":"published","title":"Plant developmental biologists meet on stairways in Matera","author":[{"full_name":"Beeckman, Tom","last_name":"Beeckman","first_name":"Tom"},{"full_name":"Friml, Jirí","last_name":"Friml","first_name":"Jirí","orcid":"0000-0002-8302-7596","id":"4159519E-F248-11E8-B48F-1D18A9856A87"}],"volume":139,"oa_version":"None","date_created":"2018-12-11T11:57:46Z","date_updated":"2021-01-12T06:57:35Z"},{"article_number":"97","license":"https://creativecommons.org/licenses/by-nc/4.0/","extern":"1","file_date_updated":"2020-07-14T12:45:41Z","publist_id":"4444","publication_status":"published","publisher":"Frontiers Research Foundation","year":"2012","date_created":"2018-12-11T11:57:47Z","date_updated":"2021-01-12T06:57:36Z","volume":3,"author":[{"full_name":"Zwiewka, Marta","last_name":"Zwiewka","first_name":"Marta"},{"first_name":"Jirí","last_name":"Friml","id":"4159519E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8302-7596","full_name":"Friml, Jirí"}],"month":"05","quality_controlled":"1","oa":1,"tmp":{"name":"Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc/4.0/legalcode","image":"/images/cc_by_nc.png","short":"CC BY-NC (4.0)"},"language":[{"iso":"eng"}],"doi":"10.3389/fpls.2012.00097","type":"journal_article","abstract":[{"text":"Coordinated, subcellular trafficking of proteins is one of the fundamental properties of the multicellular eukaryotic organisms. Trafficking involves a large diversity of compartments, pathways, cargo molecules, and vesicle-sorting events. It is also crucial in regulating the localization and, thus, the activity of various proteins, but the process is still poorly genetically defined in plants. In the past, forward genetics screens had been used to determine the function of genes by searching for a specific morphological phenotype in the organism population in which mutations had been induced chemically or by irradiation. Unfortunately, these straightforward genetic screens turned out to be limited in identifying new regulators of intracellular protein transport, because mutations affecting essential trafficking pathways often lead to lethality. In addition, the use of these approaches has been restricted by functional redundancy among trafficking regulators. Screens for mutants that rely on the observation of changes in the cellular localization or dynamics of fluorescent subcellular markers enable, at least partially, to circumvent these issues. Hence, such image-based screens provide the possibility to identify either alleles with weak effects or components of the subcellular trafficking machinery that have no strong impact on the plant growth.","lang":"eng"}],"issue":"May","status":"public","ddc":["580"],"title":"Fluorescence imaging-based forward genetic screens to identify trafficking regulators in plants","intvolume":" 3","_id":"2459","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","oa_version":"Published Version","file":[{"relation":"main_file","file_id":"6346","checksum":"ab4e9487ccdb83a7a0a9ee6811521844","date_created":"2019-04-26T06:49:26Z","date_updated":"2020-07-14T12:45:41Z","access_level":"open_access","file_name":"2012_frontiers_Zwiewka.pdf","file_size":1468230,"content_type":"application/pdf","creator":"kschuh"}],"day":"24","has_accepted_license":"1","publication":"Frontiers in Plant Science","citation":{"ama":"Zwiewka M, Friml J.
