Many models describing competition for hosts between non-interacting pathogen strains in an infinite population lead to the conclusion that selection favors invasion of new strains if and only if they have higher R0 values than the resident. Here we demonstrate that this picture fails in finite populations. Using a simple stochastic SIS model, we show that in general there is no analogous optimization principle. We find that successive invasions may in some cases lead to strains that infect a smaller fraction of the host population, and that mutually invasible pathogen strains exist. In the limit of weak selection we demonstrate that an optimization principle does exist, although it differs from R0 maximization. For strains with very large R0, we derive an expression for this local fitness function and use it to establish a lower bound for the error caused by neglecting stochastic effects. Furthermore, we apply this weak selection limit to investigate the selection dynamics in the presence of a trade-off between the virulence and the transmission rate of a pathogen."}],"publist_id":"5166","publication_status":"published","title":"Evolutionary dynamics of infectious diseases in finite populations","status":"public","intvolume":" 360","publisher":"Elsevier","department":[{"_id":"GaTk"}],"_id":"1928","year":"2014","acknowledgement":"J.H. received support from the Zdenek Bakala Foundation and the Mobility Fund of Charles University in Prague.","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","date_updated":"2021-01-12T06:54:08Z","date_created":"2018-12-11T11:54:46Z","oa_version":"None","volume":360,"author":[{"full_name":"Humplik, Jan","last_name":"Humplik","first_name":"Jan","id":"2E9627A8-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Hill, Alison","first_name":"Alison","last_name":"Hill"},{"full_name":"Nowak, Martin","first_name":"Martin","last_name":"Nowak"}]},{"author":[{"full_name":"Alexeev, V V","first_name":"V V","last_name":"Alexeev"},{"last_name":"Bogaevskaya","first_name":"V G","full_name":"Bogaevskaya, V G"},{"full_name":"Preobrazhenskaya, M M","last_name":"Preobrazhenskaya","first_name":"M M"},{"first_name":"A Y","last_name":"Ukhalov","full_name":"Ukhalov, A Y"},{"orcid":"0000-0002-9823-6833","id":"3FB178DA-F248-11E8-B48F-1D18A9856A87","last_name":"Edelsbrunner","first_name":"Herbert","full_name":"Edelsbrunner, Herbert"},{"last_name":"Yakimova","first_name":"Olga","full_name":"Yakimova, Olga"}],"date_created":"2018-12-11T11:54:46Z","date_updated":"2022-05-24T10:39:06Z","volume":203,"acknowledgement":"We would like to offer our special thanks to students of the Department of Mathematics of Demidov Yaroslavl State University A.

If the strength J of the ferromagnetic interaction is larger than a critical value J c, then the ground state is homogeneous. It has been conjectured that when J is smaller than but close to J c, the ground state is periodic and striped, with stripes of constant width h = h(J), and h → ∞ as J → Jc -. (In d = 3 stripes mean slabs, not columns.) Here we rigorously prove that, if we normalize the energy in such a way that the energy of the homogeneous state is zero, then the ratio e 0(J)/e S(J) tends to 1 as J → Jc -, with e S(J) being the energy per site of the optimal periodic striped/slabbed state and e 0(J) the actual ground state energy per site of the system. Our proof comes with explicit bounds on the difference e 0(J)-e S(J) at small but positive J c-J, and also shows that in this parameter range the ground state is striped/slabbed in a certain sense: namely, if one looks at a randomly chosen window, of suitable size ℓ (very large compared to the optimal stripe size h(J)), one finds a striped/slabbed state with high probability."}],"title":"Formation of stripes and slabs near the ferromagnetic transition","status":"public","ddc":["510"],"intvolume":" 331","_id":"1935","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"Published Version","file":[{"file_id":"11409","relation":"main_file","success":1,"checksum":"c8423271cd1e1ba9e44c47af75efe7b6","date_updated":"2022-05-24T08:30:40Z","date_created":"2022-05-24T08:30:40Z","access_level":"open_access","file_name":"2014_CommMathPhysics_Giuliani.pdf","creator":"dernst","content_type":"application/pdf","file_size":334064}],"month":"10","publication_identifier":{"eissn":["1432-0916"],"issn":["0010-3616"]},"quality_controlled":"1","external_id":{"arxiv":["1304.6344"]},"oa":1,"language":[{"iso":"eng"}],"doi":"10.1007/s00220-014-1923-2","file_date_updated":"2022-05-24T08:30:40Z","publist_id":"5159","publication_status":"published","department":[{"_id":"RoSe"}],"publisher":"Springer","acknowledgement":"2014 by the authors.

It is usually invoked in the context of challenges arising from complex intragroup structures, hierarchies, and alliances. However, a fundamental aspect of group living remains largely unexplored as a driving force in cognitive evolution: the competition between individuals searching for resources (producers) and conspecifics that parasitize their findings (scroungers). In populations of social foragers, abilities that enable scroungers to steal by outsmarting producers, and those allowing producers to prevent theft by outsmarting scroungers, are likely to be beneficial and may fuel a cognitive arms race. Using analytical theory and agent-based simulations, we present a general model for such a race that is driven by the producer-scrounger game and show that the race's plausibility is dramatically affected by the nature of the evolving abilities. If scrounging and scrounging avoidance rely on separate, strategy-specific cognitive abilities, arms races are short-lived and have a limited effect on cognition. However, general cognitive abilities that facilitate both scrounging and scrounging avoidance undergo stable, long-lasting arms races. Thus, ubiquitous foraging interactions may lead to the evolution of general cognitive abilities in social animals, without the requirement of complex intragroup structures.","lang":"eng"}],"issue":"3","status":"public","title":"An arms race between producers and scroungers can drive the evolution of social cognition","intvolume":" 25","_id":"1936","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","oa_version":"Submitted Version","scopus_import":1,"day":"13","page":"487 - 495","publication":"Behavioral Ecology","citation":{"ama":"Arbilly M, Weissman D, Feldman M, Grodzinski U.

Here, we demonstrate that cytokinin does not merely control the overall auxin flow capacity, but might also act as a polarizing cue and control the auxin stream directionality during plant organogenesis. Cytokinin enhances the PIN-FORMED1 (PIN1) auxin transporter depletion at specific polar domains, thus rearranging the cellular PIN polarities and directly regulating the auxin flow direction. This selective cytokinin sensitivity correlates with the PIN protein phosphorylation degree. PIN1 phosphomimicking mutations, as well as enhanced phosphorylation in plants with modulated activities of PIN-specific kinases and phosphatases, desensitize PIN1 to cytokinin. Our results reveal conceptually novel, cytokinin-driven polarization mechanism that operates in developmental processes involving rapid auxin stream redirection, such as lateral root organogenesis, in which a gradual PIN polarity switch defines the growth axis of the newly formed organ."}]},{"oa_version":"Submitted Version","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","_id":"1932","status":"public","title":"Cryptic genetic variation can make "irreducible complexity" a common mode of adaptation in sexual populations","intvolume":" 68","abstract":[{"lang":"eng","text":"The existence of complex (multiple-step) genetic adaptations that are "irreducible" (i.e., all partial combinations are less fit than the original genotype) is one of the longest standing problems in evolutionary biology.

Here, we demonstrate, using a simple model, that evolution can cross wide valleys to produce "irreducibly complex" adaptations by making use of previously cryptic mutations. When revealed by an evolutionary capacitor, previously cryptic mutants have higher initial frequencies than do new mutations, bringing them closer to a valley-crossing saddle in allele frequency space. Moreover, simple combinatorics implies an enormous number of candidate combinations exist within available cryptic genetic variation. We model the dynamics of crossing of a wide adaptive valley after a capacitance event using both numerical simulations and analytical approximations. Although individual valley crossing events become less likely as valleys widen, by taking the combinatorics of genotype space into account, we see that revealing cryptic variation can cause the frequent evolution of complex adaptations."}],"issue":"12","type":"journal_article","date_published":"2014-12-01T00:00:00Z","publication":"Evolution","citation":{"mla":"Trotter, Meredith, et al. “Cryptic Genetic Variation Can Make "Irreducible Complexity" a Common Mode of Adaptation in Sexual Populations.” Evolution, vol. 68, no. 12, Wiley-Blackwell, 2014, pp. 3357–67, doi:10.1111/evo.12517.","short":"M.

Removing this noise is often necessary for efficient analysis and visualization of this data, yet many denoising techniques change the minima and maxima of a scalar field. For example, the extrema can appear or disappear, spatially move, and change their value. This can lead to wrong interpretations of the data, e.g., when the maximum temperature over an area is falsely reported being a few degrees cooler because the denoising method is unaware of these features. Recently, a topological denoising technique based on a global energy optimization was proposed, which allows the topology-controlled denoising of 2D scalar fields. While this method preserves the minima and maxima, it is constrained by the size of the data. We extend this work to large 2D data and medium-sized 3D data by introducing a novel domain decomposition approach. It allows processing small patches of the domain independently while still avoiding the introduction of new critical points. Furthermore, we propose an iterative refinement of the solution, which decreases the optimization energy compared to the previous approach and therefore gives smoother results that are closer to the input. We illustrate our technique on synthetic and real-world 2D and 3D data sets that highlight potential applications."}],"issue":"12","publist_id":"5164","type":"journal_article","author":[{"full_name":"Günther, David","last_name":"Günther","first_name":"David"},{"first_name":"Alec","last_name":"Jacobson","full_name":"Jacobson, Alec"},{"full_name":"Reininghaus, Jan","id":"4505473A-F248-11E8-B48F-1D18A9856A87","first_name":"Jan","last_name":"Reininghaus"},{"full_name":"Seidel, Hans","first_name":"Hans","last_name":"Seidel"},{"full_name":"Sorkine Hornung, Olga","first_name":"Olga","last_name":"Sorkine Hornung"},{"last_name":"Weinkauf","first_name":"Tino","full_name":"Weinkauf, Tino"}],"date_created":"2018-12-11T11:54:46Z","date_updated":"2021-01-12T06:54:09Z","oa_version":"None","volume":20,"year":"2014","_id":"1930","acknowledgement":"RTRA Digiteoproject; ERC grant; SNF award; Intel Doctoral Fellowship; MPC-VCC","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","publication_status":"published","title":"Fast and memory-efficient topological denoising of 2D and 3D scalar fields","status":"public","intvolume":" 20","department":[{"_id":"HeEd"}],"publisher":"IEEE","month":"12","day":"31","scopus_import":1,"date_published":"2014-12-31T00:00:00Z","doi":"10.1109/TVCG.2014.2346432","language":[{"iso":"eng"}],"publication":"IEEE Transactions on Visualization and Computer Graphics","citation":{"mla":"Günther, David, et al. “Fast and Memory-Efficient Topological Denoising of 2D and 3D Scalar Fields.” IEEE Transactions on Visualization and Computer Graphics, vol. 20, no. 12, IEEE, 2014, pp. 2585–94, doi:10.1109/TVCG.2014.2346432.","short":"D.

Notch signaling plays a pivotal role in regulating this balance, yet the interaction between signaling and receiving cells remains poorly understood. We have found that numerous nascent neurons and/or intermediate neurogenic progenitors expressing the ligand of Notch retain apical endfeet transiently at the ventricular lumen that form adherens junctions (AJs) with the endfeet of progenitors. Forced detachment of the apical endfeet of those differentiating cells by disrupting AJs resulted in precocious neurogenesis that was preceded by the downregulation of Notch signaling. Both Notch1 and its ligand Dll1 are distributed around AJs in the apical endfeet, and these proteins physically interact with ZO-1, a constituent of the AJ. Furthermore, live imaging of a fluorescently tagged Notch1 demonstrated its trafficking from the apical endfoot to the nucleus upon cleavage. Our results identified the apical endfoot as the central site of active Notch signaling to securely prohibit inappropriate differentiation of neural progenitors.","lang":"eng"}],"type":"journal_article","volume":141,"oa_version":"None","date_updated":"2021-01-12T06:54:10Z","date_created":"2018-12-11T11:54:47Z","author":[{"full_name":"Hatakeyama, Jun","first_name":"Jun","last_name":"Hatakeyama"},{"full_name":"Wakamatsu, Yoshio","last_name":"Wakamatsu","first_name":"Yoshio"},{"first_name":"Akira","last_name":"Nagafuchi","full_name":"Nagafuchi, Akira"},{"full_name":"Kageyama, Ryoichiro","first_name":"Ryoichiro","last_name":"Kageyama"},{"first_name":"Ryuichi","last_name":"Shigemoto","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8761-9444","full_name":"Shigemoto, Ryuichi"},{"last_name":"Shimamura","first_name":"Kenji","full_name":"Shimamura, Kenji"}],"department":[{"_id":"RySh"}],"publisher":"Company of Biologists","intvolume":" 141","title":"Cadherin-based adhesions in the apical endfoot are required for active Notch signaling to control neurogenesis in vertebrates","status":"public","publication_status":"published","year":"2014","_id":"1933","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87"},{"issue":"MAY","abstract":[{"lang":"eng","text":"A wealth of experimental evidence suggests that working memory circuits preferentially represent information that is behaviorally relevant.

However, if extant variation is the result of episodes of positive selection, these genealogies may be incorrect, although this information itself may provide biologically and evolutionary meaningful information. In fact, positive Darwinian selection has been detected in the mitochondrial-encoded subunits that comprise complex I from diverse taxa with seemingly dissimilar bioenergetic life histories, but the functional implications of the selected sites are unknown. Complex I produces roughly 40% of the proton flux that is used to synthesize ATP from ADP, and a functional model based on the high-resolution structure of complex I described a unique biomechanical apparatus for proton translocation. We reported positive selection at sites in this apparatus during the evolution of Pacific salmon, and it appeared this was also the case in published reports from other taxa, but a comparison among studies was difficult because different statistical tests were used to detect selection and oftentimes, specific sites were not reported. Here we review the literature of positive selection in mitochondrial genomes, the statistical tests used to detect selection, and the structural and functional models that are currently available to study the physiological implications of selection. We then search for signatures of positive selection among the coding mitochondrial genomes of 237 species with a common set of tests and verify that the ND5 subunit of complex I is a repeated target of positive Darwinian selection in diverse taxa. We propose a novel hypothesis to explain the results based on their bioenergetic life histories and provide a guide for laboratory and field studies to test this hypothesis.","lang":"eng"}],"extern":1},{"doi":"10.1111/mmi.12507","date_published":"2014-03-01T00:00:00Z","quality_controlled":0,"page":"950 - 964","publication":"Molecular Microbiology","citation":{"ama":"Heikal A, Nakatani Y, Dunn E, et al.

NDH-2 is localized to the cytoplasmic membrane by two separated C-terminal membrane-anchoring regions that are essential for membrane localization and FAD binding, but not NDH-2 dimerization. Comparison of bacterial NDH-2 with the yeast NADH dehydrogenase (Ndi1) structure revealed non-overlapping binding sites for quinone and NADH in the bacterial enzyme. The bacterial NDH-2 structure establishes a framework for the structure-based design of small-molecule inhibitors.","lang":"eng"}],"publist_id":"5103","issue":"5","type":"journal_article"},{"extern":1,"abstract":[{"lang":"eng","text":"NADH-ubiquinone oxidoreductase (complex I) is the first and largest enzyme in the respiratory chain of mitochondria and many bacteria.

Mitochondrial complex I consists of 44 subunits of about 1 MDa in total, whilst the prokaryotic enzyme is simpler and generally consists of 14 conserved “core” subunits. Recently we have determined the first atomic structure of the entire complex I, using the enzyme from Thermus thermophilus (536 kDa, 16 subunits, 9 Fe-S clusters, 64 TM helices). Structure suggests a unique coupling mechanism, with redox energy of electron transfer driving proton translocation via long-range (up to ~200 Å) conformational changes.

The CPC was transported to overlap zones, which required two motor proteins, Kif4A and a Kif20A paralog.

Here, we reconstituted FtsA-dependent recruitment of FtsZ polymers to supported membranes, where both proteins self-organize into complex patterns, such as fast-moving filament bundles and chirally rotating rings.

Auxin distribution is regulated by auxin-dependent positive feedback loops that are not well-understood at the molecular level. Previously, we showed the involvement of the RHO of Plants (ROP) effector INTERACTOR of CONSTITUTIVELY active ROP 1 (ICR1) in regulation of auxin transport and that ICR1 levels are posttranscriptionally repressed at the site of maximum auxin accumulation at the root tip. Here, we show that bimodal regulation of ICR1 levels by auxin is essential for regulating formation of auxin local maxima and gradients. ICR1 levels increase concomitant with increase in auxin response in lateral root primordia, cotyledon tips, and provascular tissues. However, in the embryo hypophysis and root meristem, when auxin exceeds critical levels, ICR1 is rapidly destabilized by an SCF(TIR1/AFB) [SKP, Cullin, F-box (transport inhibitor response 1/auxin signaling F-box protein)]-dependent auxin signaling mechanism. Furthermore, ectopic expression of ICR1 in the embryo hypophysis resulted in reduction of auxin accumulation and concomitant root growth arrest. ICR1 disappeared during root regeneration and lateral root initiation concomitantly with the formation of a local auxin maximum in response to external auxin treatments and transiently after gravitropic stimulation. Destabilization of ICR1 was impaired after inhibition of auxin transport and signaling, proteasome function, and protein synthesis. A mathematical model based on these findings shows that an in vivo-like auxin distribution, rootward auxin flux, and shootward reflux can be simulated without assuming preexisting tissue polarity. Our experimental results and mathematical modeling indicate that regulation of auxin distribution is tightly associated with auxin-dependent ICR1 levels."}],"type":"journal_article","date_published":"2014-12-16T00:00:00Z","doi":"10.1073/pnas.1413918111","language":[{"iso":"eng"}],"oa":1,"main_file_link":[{"url":"http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4273421/","open_access":"1"}],"citation":{"ieee":"O.

In insect colonies, this protection is not restricted to the level of the individual organism, but also occurs at the societal level. Here, we review recent evidence for and insights into the mechanisms underlying individual and social immunisation in insects. We disentangle general immune-protective effects from specific immune memory (priming), and examine immunisation in the context of the lifetime of an individual and that of a colony, and of transgenerational immunisation that benefits offspring. When appropriate, we discuss parallels with disease defence strategies in human societies. We propose that recurrent parasitic threats have shaped the evolution of both the individual immune systems and colony-level social immunity in insects.","lang":"eng"}],"publist_id":"5081","issue":"10","type":"journal_article","author":[{"last_name":"El Masri","first_name":"Leila","id":"349A6E66-F248-11E8-B48F-1D18A9856A87","full_name":"El Masri, Leila"},{"full_name":"Cremer, Sylvia","id":"2F64EC8C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2193-3868","first_name":"Sylvia","last_name":"Cremer"}],"date_updated":"2021-01-12T06:54:35Z","date_created":"2018-12-11T11:55:07Z","oa_version":"None","volume":35,"year":"2014","_id":"1998","acknowledgement":"This work was funded by an ERC Starting Grant by the European Research Council (to S.C.) and the ISTFELLOW program (Co-fund Marie Curie Actions of the European Commission; to L.M.).\r\nWe thank Christopher D.

However, how these cells are efficiently activated in the network remains unclear. To address this question, I performed recordings from CA1 pyramidal neuron axons, the presynaptic fibers that provide feedback innervation of these interneurons. Two forms of axonal action potential (AP) modulation were identified. First, repetitive stimulation resulted in activity-dependent AP broadening. Broadening showed fast onset, with marked changes in AP shape following a single AP. Second, tonic depolarization in CA1 pyramidal neuron somata induced AP broadening in the axon, and depolarization-induced broadening summated with activity-dependent broadening. Outsideout patch recordings from CA1 pyramidal neuron axons revealed a high density of a-dendrotoxin (α-DTX)-sensitive, inactivating K+ channels, suggesting that K+ channel inactivation mechanistically contributes to AP broadening. To examine the functional consequences of axonal AP modulation for synaptic transmission, I performed paired recordings between synaptically connected CA1 pyramidal neurons and O-LM interneurons. CA1 pyramidal neuron-O-LM interneuron excitatory postsynaptic currents (EPSCs) showed facilitation during both repetitive stimulation and tonic depolarization of the presynaptic neuron. Both effects were mimicked and occluded by α-DTX, suggesting that they were mediated by K+ channel inactivation. Therefore, axonal AP modulation can greatly facilitate the activation of O-LM interneurons. In conclusion, modulation of AP shape in CA1 pyramidal neuron axons substantially enhances the efficacy of principal neuron-interneuron synapses, promoting the activation of O-LM interneurons in recurrent inhibitory microcircuits."}],"intvolume":" 9","ddc":["570"],"title":"Action potential modulation in CA1 pyramidal neuron axons facilitates OLM interneuron activation in recurrent inhibitory microcircuits of rat hippocampus","status":"public","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","_id":"2002","file":[{"content_type":"application/pdf","file_size":5179993,"creator":"system","file_name":"IST-2016-434-v1+1_journal.pone.0113124.pdf","access_level":"open_access","date_updated":"2020-07-14T12:45:24Z","date_created":"2018-12-12T10:14:52Z","checksum":"85e4f4ea144f827272aaf376b2830564","relation":"main_file","file_id":"5107"}],"oa_version":"Published Version","pubrep_id":"434","scopus_import":1,"has_accepted_license":"1","day":"19","citation":{"ista":"Kim S. 2014.
