--- _id: '6413' abstract: - lang: eng text: Phase-field methods have long been used to model the flow of immiscible fluids. Their ability to naturally capture interface topological changes is widely recognized, but their accuracy in simulating flows of real fluids in practical geometries is not established. We here quantitatively investigate the convergence of the phase-field method to the sharp-interface limit with simulations of two-phase pipe flow. We focus on core-annular flows, in which a highly viscous fluid is lubricated by a less viscous fluid, and validate our simulations with an analytic laminar solution, a formal linear stability analysis and also in the fully nonlinear regime. We demonstrate the ability of the phase-field method to accurately deal with non-rectangular geometry, strong advection, unsteady fluctuations and large viscosity contrast. We argue that phase-field methods are very promising for quantitatively studying moderately turbulent flows, especially at high concentrations of the disperse phase. article_processing_charge: No article_type: original author: - first_name: Baofang full_name: Song, Baofang last_name: Song - first_name: Carlos full_name: Plana, Carlos last_name: Plana - first_name: Jose M full_name: Lopez Alonso, Jose M id: 40770848-F248-11E8-B48F-1D18A9856A87 last_name: Lopez Alonso orcid: 0000-0002-0384-2022 - first_name: Marc full_name: Avila, Marc last_name: Avila citation: ama: Song B, Plana C, Lopez Alonso JM, Avila M.

Here we determined the evolutionarily-relevant segment of the fitness landscape of His3, a gene coding for an enzyme in the histidine synthesis pathway, focusing on combinations of amino acid states found at orthologous sites of extant species. Just 15% of amino acids found in yeast His3 orthologues were always neutral while the impact on fitness of the remaining 85% depended on the genetic background. Furthermore, at 67% of sites, amino acid replacements were under sign epistasis, having both strongly positive and negative effect in different genetic backgrounds. 46% of sites were under reciprocal sign epistasis. The fitness impact of amino acid replacements was influenced by only a few genetic backgrounds but involved interaction of multiple sites, shaping a rugged fitness landscape in which many of the shortest paths between highly fit genotypes are inaccessible. article_number: e1008079 article_processing_charge: No author: - first_name: Victoria full_name: Pokusaeva, Victoria id: 3184041C-F248-11E8-B48F-1D18A9856A87 last_name: Pokusaeva orcid: 0000-0001-7660-444X - first_name: Dinara R. full_name: Usmanova, Dinara R. last_name: Usmanova - first_name: Ekaterina V. full_name: Putintseva, Ekaterina V. last_name: Putintseva - first_name: Lorena full_name: Espinar, Lorena last_name: Espinar - first_name: Karen full_name: Sarkisyan, Karen id: 39A7BF80-F248-11E8-B48F-1D18A9856A87 last_name: Sarkisyan orcid: 0000-0002-5375-6341 - first_name: Alexander S. full_name: Mishin, Alexander S. last_name: Mishin - first_name: Natalya S. full_name: Bogatyreva, Natalya S. last_name: Bogatyreva - first_name: Dmitry full_name: Ivankov, Dmitry id: 49FF1036-F248-11E8-B48F-1D18A9856A87 last_name: Ivankov - first_name: Arseniy full_name: Akopyan, Arseniy id: 430D2C90-F248-11E8-B48F-1D18A9856A87 last_name: Akopyan orcid: 0000-0002-2548-617X - first_name: Sergey full_name: Avvakumov, Sergey id: 3827DAC8-F248-11E8-B48F-1D18A9856A87 last_name: Avvakumov - first_name: Inna S. full_name: Povolotskaya, Inna S. last_name: Povolotskaya - first_name: Guillaume J. full_name: Filion, Guillaume J. last_name: Filion - first_name: Lucas B. full_name: Carey, Lucas B. last_name: Carey - first_name: Fyodor full_name: Kondrashov, Fyodor id: 44FDEF62-F248-11E8-B48F-1D18A9856A87 last_name: Kondrashov orcid: 0000-0001-8243-4694 citation: ama: Pokusaeva V, Usmanova DR, Putintseva EV, et al.

The Polycomb Repressive Complexes PRC1 and PRC2 catalyse distinct chromatin modifications to enforce gene silencing, but how transcriptional repression is propagated through mitotic cell divisions remains a key unresolved question. Using reversible tethering of PcG proteins to ectopic sites in mouse embryonic stem cells, here we show that PRC1 can trigger transcriptional repression and Polycomb-dependent chromatin modifications. We find that canonical PRC1 (cPRC1), but not variant PRC1, maintains gene silencing through cell division upon reversal of tethering. Propagation of gene repression is sustained by cis-acting histone modifications, PRC2-mediated H3K27me3 and cPRC1-mediated H2AK119ub1, promoting a sequence-independent feedback mechanism for PcG protein recruitment. Thus, the distinct PRC1 complexes present in vertebrates can differentially regulate epigenetic maintenance of gene silencing, potentially enabling dynamic heritable responses to complex stimuli. Our findings reveal how PcG repression is potentially inherited in vertebrates. article_number: '1931' article_processing_charge: No author: - first_name: Hagar F. full_name: Moussa, Hagar F. last_name: Moussa - first_name: Daniel full_name: Bsteh, Daniel last_name: Bsteh - first_name: Ramesh full_name: Yelagandula, Ramesh last_name: Yelagandula - first_name: Carina full_name: Pribitzer, Carina last_name: Pribitzer - first_name: Karin full_name: Stecher, Karin last_name: Stecher - first_name: Katarina full_name: Bartalska, Katarina id: 4D883232-F248-11E8-B48F-1D18A9856A87 last_name: Bartalska - first_name: Luca full_name: Michetti, Luca last_name: Michetti - first_name: Jingkui full_name: Wang, Jingkui last_name: Wang - first_name: Jorge A. full_name: Zepeda-Martinez, Jorge A. last_name: Zepeda-Martinez - first_name: Ulrich full_name: Elling, Ulrich last_name: Elling - first_name: Jacob I. full_name: Stuckey, Jacob I. last_name: Stuckey - first_name: Lindsey I. full_name: James, Lindsey I. last_name: James - first_name: Stephen V. full_name: Frye, Stephen V. last_name: Frye - first_name: Oliver full_name: Bell, Oliver last_name: Bell citation: ama: Moussa HF, Bsteh D, Yelagandula R, et al.

Their pathogens and host disease defense mechanisms may be one component of their devastating success. First, they can introduce harmful diseases to their competitors in the introduced range, to which they themselves are tolerant. Second, their supercolonial social structure of huge multi-queen nest networks means that they will harbor a broad pathogen spectrum and high pathogen load while remaining resilient, unlike the smaller, territorial colonies of the native species. Thus, it is likely that invasive ants act as a disease reservoir, promoting their competitive advantage and invasive success. article_processing_charge: No author: - first_name: Sylvia full_name: Cremer, Sylvia id: 2F64EC8C-F248-11E8-B48F-1D18A9856A87 last_name: Cremer orcid: 0000-0002-2193-3868 citation: ama: Cremer S.
