Furthermore, the edges of these epithelial sheets commonly show finger-like protrusions whereas the bulk often displays spontaneous swirls of motile cells. To explain these experimental observations, we propose a simple flocking-type mechanism, in which cells tend to align their motility forceswith their velocity. Implementing this idea in amechanical tissue simulation, the proposed model gives rise to efficient spreading and can explain the experimentally observed long-range alignment of motility forces in highly disordered patterns, as well as the buildup of tensile stress throughout the tissue. Our model also qualitatively reproduces the dependence of swirl size and swirl velocity on cell density reported in experiments and exhibits an undulation instability at the edge of the spreading tissue commonly observed in vivo. Finally, we study the dependence of colony spreading speed on important physical and biological parameters and derive simple scaling relations that show that coordination of motility forces leads to an improvement of the wound healing process for realistic tissue parameters."}],"publication":"PNAS","language":[{"iso":"eng"}],"date_updated":"2021-01-12T08:21:55Z","acknowledgement":"This work was supported by National Science Foundation (NSF) Grant DMS-1068869 and by the NSF Center for Theoretical Biological Physics (Grant NSF PHY-0822283).\r\nWe acknowledge useful discussions with Eshel Ben-Jacob and Assaf Zaritsky.

How DDM1 interacts with other methylation pathways, such as small-RNA-directed DNA methylation (RdDM), which is thought to mediate plant asymmetric methylation through DRM enzymes, is also unclear. Here, we show that most asymmetric methylation is facilitated by DDM1 and mediated by the methyltransferase CMT2 separately from RdDM. We find that heterochromatic sequences preferentially require DDM1 for DNA methylation and that this preference depends on linker histone H1. RdDM is instead inhibited by heterochromatin and absolutely requires the nucleosome remodeler DRD1. Together, DDM1 and RdDM mediate nearly all transposon methylation and collaborate to repress transposition and regulate the methylation and expression of genes. Our results indicate that DDM1 provides DNA methyltransferases access to H1-containing heterochromatin to allow stable silencing of transposable elements in cooperation with the RdDM pathway."}],"language":[{"iso":"eng"}],"oa":1,"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","volume":153,"type":"journal_article","issue":"1","citation":{"short":"A.

Demethylation mediates parent-of-origin–specific (imprinted) gene expression but is apparently unnecessary for the extensive accumulation of maternally biased small RNA (sRNA) molecules detected in seeds. Endosperm DNA in the distantly related monocots rice and maize is likewise locally hypomethylated, but whether this hypomethylation is generally parent-of-origin specific is unknown. Imprinted expression of sRNA also remains uninvestigated in monocot seeds. Here, we report high-coverage sequencing of the Kitaake rice cultivar that enabled us to show that localized hypomethylation in rice endosperm occurs solely on the maternal genome, preferring regions of high DNA accessibility. Maternally expressed imprinted genes are enriched for hypomethylation at putative promoter regions and transcriptional termini and paternally expressed genes at promoters and gene bodies, mirroring our recent results in A. thaliana. However, unlike in A. thaliana, rice endosperm sRNA populations are dominated by specific strong sRNA-producing loci, and imprinted 24-nt sRNAs are expressed from both parental genomes and correlate with hypomethylation. Overlaps between imprinted sRNA loci and imprinted genes expressed from opposite alleles suggest that sRNAs may regulate genomic imprinting. Whereas sRNAs in seedling tissues primarily originate from small class II (cut-and-paste) transposable elements, those in endosperm are more uniformly derived, including sequences from other transposon classes, as well as genic and intergenic regions. Our data indicate that the endosperm exhibits a unique pattern of sRNA expression and suggest that localized hypomethylation of maternal endosperm DNA is conserved in flowering plants."}],"date_updated":"2021-12-14T08:26:44Z","type":"journal_article","volume":110,"keyword":["Multidisciplinary"],"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","oa":1,"date_published":"2013-05-07T00:00:00Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1073/pnas.1306164110"}],"department":[{"_id":"DaZi"}],"publication_status":"published","publication_identifier":{"issn":["0027-8424"],"eissn":["1091-6490"]},"intvolume":"       110","author":[{"last_name":"Rodrigues","first_name":"Jessica A.","full_name":"Rodrigues, Jessica A."},{"full_name":"Ruan, Randy","last_name":"Ruan","first_name":"Randy"},{"full_name":"Nishimura, Toshiro","first_name":"Toshiro","last_name":"Nishimura"},{"full_name":"Sharma, Manoj K.","first_name":"Manoj K.","last_name":"Sharma"},{"full_name":"Sharma, Rita","last_name":"Sharma","first_name":"Rita"},{"last_name":"Ronald","first_name":"Pamela C","full_name":"Ronald, Pamela C"},{"full_name":"Fischer, Robert L.","first_name":"Robert L.","last_name":"Fischer"},{"full_name":"Zilberman, Daniel","id":"6973db13-dd5f-11ea-814e-b3e5455e9ed1","orcid":"0000-0002-0123-8649","last_name":"Zilberman","first_name":"Daniel"}],"date_created":"2021-06-07T07:31:02Z","month":"05","status":"public","year":"2013","quality_controlled":"1","title":"Imprinted expression of genes and small RNA is associated with localized hypomethylation of the maternal genome in rice endosperm","scopus_import":"1","external_id":{"pmid":["23613580"]},"doi":"10.1073/pnas.1306164110","oa_version":"Published Version","publication":"Proceedings of the National Academy of Sciences","pmid":1,"article_processing_charge":"No"},{"scopus_import":"1","quality_controlled":"1","title":"A conversation across generations: Soma-germ cell crosstalk in plants","external_id":{"pmid":["23410937"]},"oa_version":"Published Version","doi":"10.1016/j.devcel.2013.01.014","publication":"Developmental Cell","pmid":1,"article_processing_charge":"No","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1016/j.devcel.2013.01.014"}],"date_published":"2013-02-11T00:00:00Z","publication_status":"published","department":[{"_id":"DaZi"},{"_id":"XiFe"}],"date_created":"2021-06-08T06:14:50Z","publication_identifier":{"eissn":["1878-1551"],"issn":["1534-5807"]},"intvolume":"        24","author":[{"last_name":"Feng","first_name":"Xiaoqi","full_name":"Feng, Xiaoqi","id":"e0164712-22ee-11ed-b12a-d80fcdf35958","orcid":"0000-0002-4008-1234"},{"orcid":"0000-0002-0123-8649","full_name":"Zilberman, Daniel","id":"6973db13-dd5f-11ea-814e-b3e5455e9ed1","first_name":"Daniel","last_name":"Zilberman"},{"last_name":"Dickinson","first_name":"Hugh","full_name":"Dickinson, Hugh"}],"year":"2013","month":"02","status":"public","issue":"3","citation":{"ieee":"X.

The band structure of ABA-stacked trilayer graphene consists of a monolayer-like and a bilayer-like pair of bands. Here we study electronic properties of ABA-stacked trilayer graphene biased by a perpendicular electric field. We find that the combination of the bias and trigonal warping gives rise to a set of new Dirac points: In each valley, seven species of Dirac fermions with small masses of order of a few meV emerge. The positions and masses of the emergent Dirac fermions are tunable by bias, and one group of Dirac fermions becomes massless at a certain bias value. Therefore, in contrast to bilayer graphene, the conductivity at the neutrality point is expected to show nonmonotonic behavior, becoming of the order of a few e2/h when some Dirac masses vanish. Further, we analyze the evolution of the Landau level spectrum as a function of bias. The emergence of new Dirac points in the band structure translates into new threefold-degenerate groups of Landau levels. This leads to an anomalous quantum Hall effect, in which some quantum Hall steps have a height of 3e2/h. At an intermediate bias, the degeneracies of all Landau levels get lifted, and in this regime all quantum Hall plateaus are spaced by e2/h. Finally, we show that the pattern of Landau level crossings is very sensitive to certain band structure parameters, and can therefore provide a useful tool for determining their precise values.","lang":"eng"}],"publication":"Physical Review B - Condensed Matter and Materials Physics","oa":1,"type":"journal_article","volume":87},{"type":"journal_article","volume":87,"oa":1,"publication":"Physical Review B - Condensed Matter and Materials Physics","abstract":[{"lang":"eng","text":"We study the stability of the normal state in a mesoscopic NSN junction biased by a constant voltage V with respect to the formation of the superconducting order.

For sufficiently low biases, a stationary symmetric superconducting state emerges below the instability line. For higher biases, the normal phase is destroyed by the formation of a nonstationary bimodal state with two superconducting nuclei localized near the opposite terminals. The low-temperature and large-voltage behavior of the instability line is highly sensitive to the details of the inelastic relaxation mechanism in the wire.

Our work paves the way for engineering the Dirac band gap and realizing interaction-driven topological quantum phenomena in TCIs.","lang":"eng"}],"page":"1496 - 1499","_id":"972","publisher":"American Association for the Advancement of Science","day":"01","extern":"1","external_id":{"arxiv":["1305.2823"]},"doi":"10.1126/science.1239451","oa_version":"Preprint","quality_controlled":"1","title":"Observation of dirac node formation and mass acquisition in a topological crystalline insulator","publication":"Science","publication_status":"published","main_file_link":[{"url":"https://arxiv.org/abs/1305.2823","open_access":"1"}],"date_published":"2013-01-01T00:00:00Z","year":"2013","month":"01","status":"public","arxiv":1,"date_created":"2018-12-11T11:49:29Z","publist_id":"6430","intvolume":"       341","author":[{"full_name":"Okada, Yoshinori","last_name":"Okada","first_name":"Yoshinori"},{"orcid":"0000-0002-2399-5827","id":"47809E7E-F248-11E8-B48F-1D18A9856A87","full_name":"Serbyn, Maksym","first_name":"Maksym","last_name":"Serbyn"},{"first_name":"Hsin","last_name":"Lin","full_name":"Lin, Hsin"},{"full_name":"Walkup, Daniel","last_name":"Walkup","first_name":"Daniel"},{"full_name":"Zhou, Wenwen","first_name":"Wenwen","last_name":"Zhou"},{"full_name":"Dhital, Chetan","last_name":"Dhital","first_name":"Chetan"},{"full_name":"Neupane, Madhab","first_name":"Madhab","last_name":"Neupane"},{"last_name":"Xu","first_name":"Suyang","full_name":"Xu, Suyang"},{"full_name":"Wang, Yungjui","first_name":"Yungjui","last_name":"Wang"},{"full_name":"Sankar, Raman","first_name":"Raman","last_name":"Sankar"},{"full_name":"Chou, Fangcheng","last_name":"Chou","first_name":"Fangcheng"},{"first_name":"Arun","last_name":"Bansil","full_name":"Bansil, Arun"},{"last_name":"Hasan","first_name":"Md","full_name":"Hasan, Md"},{"full_name":"Wilson, Stephen","first_name":"Stephen","last_name":"Wilson"},{"full_name":"Fu, Liang","last_name":"Fu","first_name":"Liang"},{"full_name":"Madhavan, Vidya","last_name":"Madhavan","first_name":"Vidya"}]},{"year":"2013","status":"public","_id":"973","month":"09","date_created":"2018-12-11T11:49:29Z","day":"17","publisher":"American Physical Society","author":[{"orcid":"0000-0002-2399-5827","full_name":"Maksym Serbyn","id":"47809E7E-F248-11E8-B48F-1D18A9856A87","first_name":"Maksym","last_name":"Serbyn"},{"full_name":"Papić, Zlatko","last_name":"Papić","first_name":"Zlatko"},{"full_name":"Abanin, Dmitry A","first_name":"Dmitry","last_name":"Abanin"}],"extern":1,"intvolume":"       111","publist_id":"6424","publication_status":"published","date_published":"2013-09-17T00:00:00Z","main_file_link":[{"url":"https://arxiv.org/abs/1305.5554","open_access":"1"}],"oa":1,"type":"journal_article","volume":111,"date_updated":"2021-01-12T08:22:21Z","acknowledgement":"We thank J.

Here we study direct reciprocity in the context of the alternating Prisoner's Dilemma. We consider all strategies that can be implemented by one and two-state automata. We calculate the payoff matrix of all pairwise encounters in the presence of noise. We explore deterministic selection dynamics with and without mutation. Using different error rates and payoff values, we observe convergence to a small number of distinct equilibria. Two of them are uncooperative strict Nash equilibria representing always-defect (ALLD) and Grim. The third equilibrium is mixed and represents a cooperative alliance of several strategies, dominated by a strategy which we call Forgiver. Forgiver cooperates whenever the opponent has cooperated; it defects once when the opponent has defected, but subsequently Forgiver attempts to re-establish cooperation even if the opponent has defected again. Forgiver is not an evolutionarily stable strategy, but the alliance, which it rules, is asymptotically stable. For a wide range of parameter values the most commonly observed outcome is convergence to the mixed equilibrium, dominated by Forgiver. Our results show that although forgiving might incur a short-term loss it can lead to a long-term gain. Forgiveness facilitates stable cooperation in the presence of exploitation and noise.","lang":"eng"}],"date_updated":"2025-09-29T14:30:03Z","type":"research_data_reference","article_processing_charge":"No","user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","date_published":"2013-12-12T00:00:00Z","department":[{"_id":"KrCh"}],"author":[{"full_name":"Zagorsky, Benjamin","last_name":"Zagorsky","first_name":"Benjamin"},{"last_name":"Reiter","first_name":"Johannes","id":"4A918E98-F248-11E8-B48F-1D18A9856A87","full_name":"Reiter, Johannes","orcid":"0000-0002-0170-7353"},{"full_name":"Chatterjee, Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4561-241X","last_name":"Chatterjee","first_name":"Krishnendu"},{"full_name":"Nowak, Martin","first_name":"Martin","last_name":"Nowak"}],"related_material":{"record":[{"relation":"used_in_publication","status":"public","id":"2247"}]},"date_created":"2021-07-28T15:45:07Z","day":"12","publisher":"Public Library of Science","status":"public","month":"12","_id":"9749","year":"2013"},{"year":"2013","month":"06","_id":"975","status":"public","day":"28","publisher":"American Physical Society","date_created":"2018-12-11T11:49:29Z","publist_id":"6426","intvolume":"       110","author":[{"last_name":"Serbyn","first_name":"Maksym","id":"47809E7E-F248-11E8-B48F-1D18A9856A87","full_name":"Maksym Serbyn","orcid":"0000-0002-2399-5827"},{"last_name":"Papić","first_name":"Zlatko","full_name":"Papić, Zlatko"},{"first_name":"Dmitry","last_name":"Abanin","full_name":"Abanin, Dmitry A"}],"extern":1,"publication_status":"published","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1304.4605"}],"date_published":"2013-06-28T00:00:00Z","oa":1,"volume":110,"type":"journal_article","acknowledgement":"We would like to thank E.

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"}],"citation":{"ista":"Serbyn M, Papić Z, Abanin D. 2013.

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."}],"date_updated":"2025-09-29T13:41:12Z","article_processing_charge":"No","type":"research_data_reference","oa":1,"user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","date_published":"2013-03-21T00:00:00Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.5061/dryad.b1q2n"}],"department":[{"_id":"CaGu"}],"author":[{"full_name":"Refardt, Dominik","first_name":"Dominik","last_name":"Refardt"},{"last_name":"Bergmiller","first_name":"Tobias","full_name":"Bergmiller, Tobias","id":"2C471CFA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5396-4346"},{"first_name":"Rolf","last_name":"Kümmerli","full_name":"Kümmerli, Rolf"}],"related_material":{"record":[{"id":"2853","status":"public","relation":"used_in_publication"}]},"date_created":"2021-07-30T08:08:09Z","publisher":"Dryad","day":"21","status":"public","month":"03","_id":"9751","year":"2013"},{"year":"2013","month":"10","_id":"9754","status":"public","publisher":"Dryad","day":"01","date_created":"2021-07-30T08:31:22Z","related_material":{"record":[{"status":"public","id":"2170","relation":"used_in_publication"}]},"author":[{"first_name":"Jack","last_name":"Hearn","full_name":"Hearn, Jack"},{"first_name":"Graham","last_name":"Stone","full_name":"Stone, Graham"},{"id":"4880FE40-F248-11E8-B48F-1D18A9856A87","full_name":"Barton, Nicholas H","orcid":"0000-0002-8548-5240","last_name":"Barton","first_name":"Nicholas H"},{"last_name":"Lohse","first_name":"Konrad","full_name":"Lohse, Konrad"},{"first_name":"Lynsey","last_name":"Bunnefeld","full_name":"Bunnefeld, Lynsey"}],"department":[{"_id":"NiBa"}],"date_published":"2013-10-01T00:00:00Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.5061/dryad.r3r60"}],"user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","oa":1,"article_processing_charge":"No","type":"research_data_reference","date_updated":"2025-09-29T11:38:51Z","abstract":[{"text":"Short-read sequencing technologies have in principle made it feasible to draw detailed inferences about the recent history of any organism. 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"}],"citation":{"ista":"Hearn J, Stone G, Barton NH, Lohse K, Bunnefeld L. 2013.

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.","lang":"eng"}],"publication":"Physical Review B - Condensed Matter and Materials Physics","acknowledgement":"M.

The critical initiating factor appears to be the maternal immune activation (MIA) that follows infection. This process can be induced in rodents by exposure of pregnant dams to the viral mimic Poly I:C, which triggers an immune response that results in structural, functional, behavioral, and electrophysiological phenotypes in the adult offspring that model those seen in schizophrenia. We used this model to explore the role of synchronization in brain neural networks, a process thought to be dysfunctional in schizophrenia and previously associated with positive, negative, and cognitive symptoms of schizophrenia. Exposure of pregnant dams to Poly I:C on GD15 produced an impairment in long-range neural synchrony in adult offspring between two regions implicated in schizophrenia pathology; the hippocampus and the medial prefrontal cortex (mPFC). This reduction in synchrony was ameliorated by acute doses of the antipsychotic clozapine. MIA animals have previously been shown to have impaired pre-pulse inhibition (PPI), a gold-standard measure of schizophrenia-like deficits in animal models. Our data showed that deficits in synchrony were positively correlated with the impairments in PPI. Subsequent analysis of LFP activity during the PPI response also showed that reduced coupling between the mPFC and the hippocampus following processing of the pre-pulse was associated with reduced PPI. The ability of the MIA intervention to model neurodevelopmental aspects of schizophrenia pathology provides a useful platform from which to investigate the ontogeny of aberrant synchronous processes. Further, the way in which the model expresses translatable deficits such as aberrant synchrony and reduced PPI will allow researchers to explore novel intervention strategies targeted to these changes.

Historically, fractional killing has been attributed to infrequently dividing or nondividing &quot;persisters.&quot; Using microfluidic cultures and time-lapse microscopy, we found that Mycobacterium smegmatis persists by dividing in the presence of the drug isoniazid (INH). Although persistence in these studies was characterized by stable numbers of cells, this apparent stability was actually a dynamic state of balanced division and death. Single cells expressed catalase-peroxidase (KatG), which activates INH, in stochastic pulses that were negatively correlated with cell survival. These behaviors may reflect epigenetic effects, because KatG pulsing and death were correlated between sibling cells. Selection of lineages characterized by infrequent KatG pulsing could allow nonresponsive adaptation during prolonged drug exposure."}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","volume":339,"type":"journal_article","page":"91 - 95","publisher":"American Association for the Advancement of Science","day":"04","_id":"499","scopus_import":"1","quality_controlled":"1","title":"Dynamic persistence of antibiotic-stressed mycobacteria","external_id":{"isi":["000312985800059"]},"doi":"10.1126/science.1229858","oa_version":"None","publication":"Science","article_processing_charge":"No","date_published":"2013-01-04T00:00:00Z","publication_status":"published","department":[{"_id":"CaGu"},{"_id":"GaTk"}],"date_created":"2018-12-11T11:46:48Z","isi":1,"publist_id":"7321","intvolume":"       339","author":[{"last_name":"Wakamoto","first_name":"Yurichi","full_name":"Wakamoto, Yurichi"},{"full_name":"Dhar, Neraaj","first_name":"Neraaj","last_name":"Dhar"},{"last_name":"Chait","first_name":"Remy P","full_name":"Chait, Remy P","id":"3464AE84-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-0876-3187"},{"first_name":"Katrin","last_name":"Schneider","full_name":"Schneider, Katrin"},{"full_name":"Signorino Gelo, François","last_name":"Signorino Gelo","first_name":"François"},{"full_name":"Leibler, Stanislas","last_name":"Leibler","first_name":"Stanislas"},{"last_name":"Mckinney","first_name":"John","full_name":"Mckinney, John"}],"year":"2013","month":"01","status":"public"}]
