We show that this surprising phenomenon results from the dephasing due to exponentially small interaction-induced corrections to the eigenenergies of different states. For weak interactions, we find that the entanglement entropy grows as ξln (Vt/), where V is the interaction strength, and ξ is the single-particle localization length. The saturated value of the entanglement entropy at long times is determined by the participation ratios of the initial state over the eigenstates of the subsystem. Our work shows that the logarithmic entanglement growth is a universal phenomenon characteristic of the many-body localized phase in any number of spatial dimensions, and reveals a broad hierarchy of dephasing time scales present in such a phase.","lang":"eng"}],"quality_controlled":0,"extern":1},{"department":[{"_id":"CaGu"}],"title":"Data from: Altruism can evolve when relatedness is low: evidence from bacteria committing suicide upon phage infection","publisher":"Dryad","date_created":"2021-07-30T08:08:09Z","oa_version":"Published Version","date_published":"2013-03-21T00:00:00Z","author":[{"last_name":"Refardt","first_name":"Dominik","full_name":"Refardt, Dominik"},{"id":"2C471CFA-F248-11E8-B48F-1D18A9856A87","full_name":"Bergmiller, Tobias","orcid":"0000-0001-5396-4346","last_name":"Bergmiller","first_name":"Tobias"},{"first_name":"Rolf","last_name":"Kümmerli","full_name":"Kümmerli, Rolf"}],"article_processing_charge":"No","doi":"10.5061/dryad.b1q2n","date_updated":"2023-10-18T06:43:22Z","related_material":{"record":[{"relation":"used_in_publication","status":"public","id":"2853"}]},"abstract":[{"lang":"eng","text":"High relatedness among interacting individuals has generally been considered a precondition for the evolution of altruism. However, kin-selection theory also predicts the evolution of altruism when relatedness is low, as long as the cost of the altruistic act is minor compared to its benefit. Here, we demonstrate evidence for a low-cost altruistic act in bacteria. We investigated Escherichia coli responding to the attack of an obligately lytic phage by committing suicide in order to prevent parasite transmission to nearby relatives. We found that bacterial suicide provides large benefits to survivors at marginal costs to committers. The cost of suicide was low because infected cells are moribund, rapidly dying upon phage infection, such that no more opportunity for reproduction remains. As a consequence of its marginal cost, host suicide was selectively favoured even when relatedness between committers and survivors approached zero. Altogether, our findings demonstrate that low-cost suicide can evolve with ease, represents an effective host-defence strategy, and seems to be widespread among microbes. Moreover, low-cost suicide might also occur in higher organisms as exemplified by infected social insect workers leaving the colony to die in isolation."}],"user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","type":"research_data_reference","main_file_link":[{"url":"https://doi.org/10.5061/dryad.b1q2n","open_access":"1"}],"_id":"9751","year":"2013","oa":1,"status":"public","day":"21","citation":{"ieee":"D.

In practice, however, this remains challenging due to the difficulty of genome assembly in most organisms and the lack of statistical methods powerful enough to discriminate among recent, non-equilibrium histories. We address both the assembly and inference challenges. We develop a bioinformatic pipeline for generating outgroup-rooted alignments of orthologous sequence blocks from de novo low-coverage short-read data for a small number of genomes, and show how such sequence blocks can be used to fit explicit models of population divergence and admixture in a likelihood framework. To illustrate our approach, we reconstruct the Pleistocene history of an oak-feeding insect (the oak gallwasp Biorhiza pallida) which, in common with many other taxa, was restricted during Pleistocene ice ages to a longitudinal series of southern refugia spanning theWestern Palaearctic. Our analysis of sequence blocks sampled from a single genome from each of three major glacial refugia reveals support for an unexpected history dominated by recent admixture. Despite the fact that 80% of the genome is affected by admixture during the last glacial cycle, we are able to infer the deeper divergence history of these populations. These inferences are robust to variation in block length, mutation model, and the sampling location of individual genomes within refugia. This combination of de novo assembly and numerical likelihood calculation provides a powerful framework for estimating recent population history that can be applied to any organism without the need for prior genetic resources.","lang":"eng"}],"article_processing_charge":"No","related_material":{"record":[{"status":"public","relation":"used_in_publication","id":"2170"}]},"doi":"10.5061/dryad.r3r60","date_updated":"2023-02-23T10:31:17Z","date_published":"2013-10-01T00:00:00Z","author":[{"last_name":"Hearn","first_name":"Jack","full_name":"Hearn, Jack"},{"last_name":"Stone","first_name":"Graham","full_name":"Stone, Graham"},{"first_name":"Nicholas H","last_name":"Barton","orcid":"0000-0002-8548-5240","full_name":"Barton, Nicholas H","id":"4880FE40-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Lohse, Konrad","first_name":"Konrad","last_name":"Lohse"},{"last_name":"Bunnefeld","first_name":"Lynsey","full_name":"Bunnefeld, Lynsey"}],"year":"2013","main_file_link":[{"open_access":"1","url":"https://doi.org/10.5061/dryad.r3r60"}],"_id":"9754","user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","type":"research_data_reference","month":"10","citation":{"ieee":"J.

We consider the case of algebraic spin liquid, when spinons have fermionic statistics and a Dirac-like dispersion. We establish the general procedure for deriving spinon-phonon interactions, which is based on symmetry considerations. The procedure is illustrated for four different algebraic spin liquids: π-flux and staggered-flux phases on a square lattice, π-flux phase on a kagome lattice, and zero-flux phase on a honeycomb lattice. Although the low-energy description is similar for all these phases, different underlying symmetry groups lead to a distinct form of spinon-phonon interaction Hamiltonian. The explicit form of the spinon-phonon interaction is used to estimate the attenuation of ultrasound in an algebraic spin liquid. The prospects of the sound attenuation as a probe of spinons are discussed."}],"doi":"10.1103/PhysRevB.87.174424","date_updated":"2021-01-12T08:22:22Z","date_published":"2013-05-22T00:00:00Z","author":[{"id":"47809E7E-F248-11E8-B48F-1D18A9856A87","full_name":"Maksym Serbyn","last_name":"Serbyn","orcid":"0000-0002-2399-5827","first_name":"Maksym"},{"last_name":"Lee","first_name":"Patrick","full_name":"Lee, Patrick"}]},{"article_processing_charge":"No","doi":"10.1021/ja400472m","date_updated":"2021-01-12T07:43:21Z","date_published":"2013-03-07T00:00:00Z","author":[{"first_name":"Wenhua","last_name":"Li","full_name":"Li, Wenhua"},{"full_name":"Zamani, Reza","last_name":"Zamani","first_name":"Reza"},{"first_name":"Maria","last_name":"Ibáñez","orcid":"0000-0001-5013-2843","full_name":"Ibáñez, Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Doris","last_name":"Cadavid","full_name":"Cadavid, Doris"},{"last_name":"Shavel","first_name":"Alexey","full_name":"Shavel, Alexey"},{"full_name":"Morante, Joan","first_name":"Joan","last_name":"Morante"},{"last_name":"Arbiol","first_name":"Jordi","full_name":"Arbiol, Jordi"},{"last_name":"Cabot","first_name":"Andreu","full_name":"Cabot, Andreu"}],"extern":"1","quality_controlled":"1","abstract":[{"lang":"eng","text":"Morphology is a key parameter in the design of novel nanocrystals and nanomaterials with controlled functional properties.

In the present work, we use PbTe-PbS as the model material system and thermoelectricity as the paradigmatic application to investigate the potential of the bottom-up assembly of core-shell nanoparticles to produce functional nanocomposites. With this goal in mind, a rapid, high-yield and scalable colloidal synthetic route to prepare grams of PbTe@PbS core-shell nanoparticles with unprecedented narrow size distributions and exceptional composition control is detailed. PbTe@PbS nanoparticles were used as building blocks for the bottom-up production of PbTe-PbS nanocomposites with tuned composition. In such PbTe-PbS nanocomposites, synergistic nanocrystal doping effects result in up to 10-fold higher electrical conductivities than in pure PbTe and PbS nanomaterials. At the same time, the acoustic impedance mismatch between PbTe and PbS phases and a partial phase alloying provide PbTe-PbS nanocomposites with strongly reduced thermal conductivities. As a result, record thermoelectric figures of merit (ZT) of ∼1.1 were obtained from undoped PbTe and PbS phases at 710 K.

An automated pulsed spray-deposition system was used to deposit the nanoparticles into homogeneous and crack-free films with controlled thickness. After annealing the film in a Se-rich atmosphere, carbon-free and crystalline Cu2ZnSnSe4 absorber layers were obtained. Not only was crystallization promoted by the complete removal of organics, but also Sb itself played a critical role. The Sb-assisted crystal growth is associated with the formation of a Sb-based compound at the grain boundaries, which locally reduces the melting point, thus promoting the film diffusion-limited crystallization.

We detected no evidence of outbreeding depression, with inter-population hybrids and backcrosses showing either similar fitness or significant heterosis for fitness components across the three generations. Variation in heterosis among population pairs was best explained by characteristics of the foreign source or home population, and was greatest when the source population was large, with high genetic diversity and low inbreeding, and the home population was small and inbred. Our results indicate that the primary consideration for maximizing progeny fitness following population augmentation or restoration is the use of seed from large, genetically diverse populations."}],"publisher":"Royal Society, The","publication":"Proceedings of the Royal Society of London Series B Biological Sciences","department":[{"_id":"NiBa"}],"title":"Source population characteristics affect heterosis following genetic rescue of fragmented plant populations","publist_id":"7372","date_created":"2018-12-11T11:46:32Z","oa_version":"Submitted Version","issue":"1750","external_id":{"pmid":["23173202"]},"oa":1,"status":"public","citation":{"ista":"Pickup M, Field D, Rowell D, Young A. 2013.

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."}],"date_updated":"2021-01-12T06:57:30Z","date_published":"2012-01-01T00:00:00Z","author":[{"full_name":"Čadek, Martin","last_name":"Čadek","first_name":"Martin"},{"full_name":"Marek Krcál","id":"33E21118-F248-11E8-B48F-1D18A9856A87","first_name":"Marek","last_name":"Krcál"},{"first_name":"Jiří","last_name":"Matoušek","full_name":"Matoušek, Jiří"},{"full_name":"Sergeraert, Francis","first_name":"Francis","last_name":"Sergeraert"},{"first_name":"Lukáš","last_name":"Vokřínek","full_name":"Vokřínek, Lukáš"},{"first_name":"Uli","orcid":"0000-0002-1494-0568","last_name":"Wagner","full_name":"Uli Wagner","id":"36690CA2-F248-11E8-B48F-1D18A9856A87"}]},{"title":"On Laplacians of random complexes","publisher":"ACM","date_created":"2018-12-11T11:57:41Z","conference":{"name":"SGC: Symposuim on Computational Geometry"},"publist_id":"4464","date_published":"2012-06-01T00:00:00Z","author":[{"first_name":"Anna","last_name":"Gundert","full_name":"Gundert, Anna"},{"full_name":"Uli Wagner","id":"36690CA2-F248-11E8-B48F-1D18A9856A87","first_name":"Uli","orcid":"0000-0002-1494-0568","last_name":"Wagner"}],"doi":"10.1145/2261250.2261272","date_updated":"2021-01-12T06:57:30Z","abstract":[{"text":"Eigenvalues associated to graphs are a well-studied subject. 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 &gt; 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"}],"extern":1,"quality_controlled":0,"page":"151 - 160","type":"conference","_id":"2441","publication_status":"published","year":"2012","status":"public","day":"01","citation":{"chicago":"Gundert, Anna, and Uli Wagner. “On Laplacians of Random Complexes,” 151–60.

To identify novel molecular components of endocytic recycling, mainly exocytosis, we designed a PIN1-green fluorescent protein fluorescence imaging-based forward genetic screen for Arabidopsis thaliana mutants that showed increased intracellular accumulation of cargos in response to the trafficking inhibitor brefeldin A (BFA). 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. BEX5/RabA1b localizes to trans-Golgi network/early endosomes (TGN/EE) and acts on distinct trafficking processes like those regulated by GTP exchange factors on ADP-ribosylation factors GNOM-LIKE1 and HOPM INTERACTOR7/BFA-VISUALIZED ENDOCYTIC TRAFFICKING DEFECTIVE1, which regulate trafficking at the Golgi apparatus and TGN/EE, respectively. All together, this study identifies Arabidopsis BEX5/RabA1b as a novel regulator of protein trafficking from a TGN/EE compartment to the plasma membrane."}]},{"title":"Plant developmental biologists meet on stairways in Matera","publication":"Development","publisher":"Company of Biologists","oa_version":"None","date_created":"2018-12-11T11:57:46Z","publist_id":"4447","author":[{"full_name":"Beeckman, Tom","last_name":"Beeckman","first_name":"Tom"},{"first_name":"Jirí","last_name":"Friml","orcid":"0000-0002-8302-7596","full_name":"Friml, Jirí","id":"4159519E-F248-11E8-B48F-1D18A9856A87"}],"date_published":"2012-10-15T00:00:00Z","doi":"10.1242/dev.080861","date_updated":"2021-01-12T06:57:35Z","abstract":[{"text":"The third EMBO Conference on Plant Molecular Biology, which focused on ‘Plant development and environmental interactions’,was held in May 2012 in Matera, Italy.
