--- _id: '767' abstract: - lang: eng text: Synchronous distributed algorithms are easier to design and prove correct than algorithms that tolerate asynchrony. Yet, in the real world, networks experience asynchrony and other timing anomalies. In this paper, we address the question of how to efficiently transform an algorithm that relies on synchronous timing into an algorithm that tolerates asynchronous executions. We introduce a transformation technique from synchronous algorithms to indulgent algorithms (Guerraoui, in PODC, pp. 289-297, 2000), which induces only a constant overhead in terms of time complexity in well-behaved executions. Our technique is based on a new abstraction we call an asynchrony detector, which the participating processes implement collectively. The resulting transformation works for the class of colorless distributed tasks, including consensus and set agreement. Interestingly, we also show that our technique is relevant for colored tasks, by applying it to the renaming problem, to obtain the first indulgent renaming algorithm. acknowledgement: "Dan Alistarh was supported by the NCCR MICS Project.

Herein we develop a framework to examine population‐level patterns of reproduction and survival across lifespan in long‐lived organisms, and decompose those changes into individual‐level effects, and the effects of age‐specific trade‐offs between fitness components. We apply this to an extensive longitudinal dataset on female semi‐captive Asian timber elephants (Elephas maximus) and report the first evidence of age‐specific fitness declines that are driven by age‐specific associations between fitness components in a long‐lived mammal. Associations between reproduction and survival are positive in early life, but negative in later life with up to 71% of later‐life survival declines associated with investing in the production of offspring within this population of this critically endangered species. article_processing_charge: No article_type: original author: - first_name: Matthew Richard full_name: Robinson, Matthew Richard id: E5D42276-F5DA-11E9-8E24-6303E6697425 last_name: Robinson orcid: 0000-0001-8982-8813 - first_name: Khyne U full_name: Mar, Khyne U last_name: Mar - first_name: Virpi full_name: Lummaa, Virpi last_name: Lummaa citation: ama: Robinson MR, Mar KU, Lummaa V.

We found consistent heritable differences between females in their choice of mate based on ornament size during a 25‐year study of a population of collared flycatchers. However, the fitness consequences of mate choice were dependent on environmental conditions experienced whilst breeding. Females breeding with highly ornamented males experienced high relative fitness during dry summer conditions, but low relative fitness during wetter years. Our results imply that sexual selection within a population can be highly variable and dependent upon the prevailing weather conditions experienced by individuals. article_processing_charge: No article_type: original author: - first_name: Matthew Richard full_name: Robinson, Matthew Richard id: E5D42276-F5DA-11E9-8E24-6303E6697425 last_name: Robinson orcid: 0000-0001-8982-8813 - first_name: G. full_name: Sander van Doorn, G. last_name: Sander van Doorn - first_name: Lars full_name: Gustafsson, Lars last_name: Gustafsson - first_name: Anna full_name: Qvarnström, Anna last_name: Qvarnström citation: ama: Robinson MR, Sander van Doorn G, Gustafsson L, Qvarnström A.

There is a 1/N correction to the discrete jump in the contact number at the transition so that jammed packings exist only above isostaticity. As a result, the canonical power-law scalings of the contact number and elastic moduli break down at low pressure. These quantities exhibit scaling collapse with a nontrivial scaling function, demonstrating that the jamming transition can be considered a phase transition. Scaling is achieved as a function of N in both two and three dimensions, indicating an upper critical dimension of 2. article_number: '095704' article_processing_charge: No article_type: original author: - first_name: Carl Peter full_name: Goodrich, Carl Peter id: EB352CD2-F68A-11E9-89C5-A432E6697425 last_name: Goodrich orcid: 0000-0002-1307-5074 - first_name: Andrea J. full_name: Liu, Andrea J. last_name: Liu - first_name: Sidney R. full_name: Nagel, Sidney R. last_name: Nagel citation: ama: Goodrich CP, Liu AJ, Nagel SR.

In the pathogenic filamentous fungus Aspergillus fumigatus, this polysaccharide is made of a linear mannan backbone with side chains of galactofuran and is anchored to the plasma membrane via a glycosylphosphatidylinositol or is covalently linked to the cell wall. To date, the biosynthesis and significance of this polysaccharide are unknown. The present data demonstrate that deletion of the Golgi UDP-galactofuranose transporter GlfB or the GDP-mannose transporter GmtA leads to the absence of galactofuran or galactomannan, respectively. This indicates that the biosynthesis of galactomannan probably occurs in the lumen of the Golgi apparatus and thus contrasts with the biosynthesis of other fungal cell wall polysaccharides studied to date that takes place at the plasma membrane. Transglycosylation of galactomannan from the membrane to the cell wall is hypothesized because both the cell wall-bound and membrane-bound polysaccharide forms are affected in the generated mutants. Considering the severe growth defect of the A. fumigatus GmtA-deficient mutant, proving this paradigm might provide new targets for antifungal therapy. acknowledgement: This work was supported by the Deutsche Forschungsgemeinschaft. article_processing_charge: No article_type: original author: - first_name: Jakob full_name: Engel, Jakob last_name: Engel - first_name: Philipp S full_name: Schmalhorst, Philipp S id: 309D50DA-F248-11E8-B48F-1D18A9856A87 last_name: Schmalhorst orcid: 0000-0002-5795-0133 - first_name: Françoise full_name: Routier, Françoise last_name: Routier citation: ama: Engel J, Schmalhorst PS, Routier F.

One is induced by the presence of near-critical eigenvalues in the connectivity matrix W, producing large but slow activity fluctuations along the corresponding eigenvectors (dynamical slowing). The other relies on W not being normal, which allows the network activity to make large but fast excursions along specific directions. Here we investigate the trade-off between non-normal amplification and dynamical slowing in the spontaneous activity of large random neuronal networks composed of excitatory and inhibitory neurons. We use a Schur decomposition of W to separate the two amplification mechanisms. Assuming linear stochastic dynamics, we derive an exact expression for the expected amount of purely non-normal amplification. We find that amplification is very limited if dynamical slowing must be kept weak. We conclude that, to achieve strong transient amplification with little slowing, the connectivity must be structured. We show that unidirectional connections between neurons of the same type together with reciprocal connections between neurons of different types, allow for amplification already in the fast dynamical regime. Finally, our results also shed light on the differences between balanced networks in which inhibition exactly cancels excitation and those where inhibition dominates. article_number: '011909' article_processing_charge: No article_type: original author: - first_name: Guillaume full_name: Hennequin, Guillaume last_name: Hennequin - first_name: Tim P full_name: Vogels, Tim P id: CB6FF8D2-008F-11EA-8E08-2637E6697425 last_name: Vogels orcid: 0000-0003-3295-6181 - first_name: Wulfram full_name: Gerstner, Wulfram last_name: Gerstner citation: ama: Hennequin G, Vogels TP, Gerstner W.

When branch sites were observed closely spaced on the same filament their separation was commonly a multiple of the actin helical repeat of 36 nm. Image averaging of branch junctions in the tomograms yielded a model for the in vivo branch at 2.9 nm resolution, which was comparable with that derived for the in vitro actin- Arp2/3 complex. Lamellipodium initiation was monitored in an intracellular wound-healing model and was found to involve branching from the sides of actin filaments oriented parallel to the plasmalemma. Many filament plus ends, presumably capped, terminated behind the lamellipodium tip and localized on the dorsal and ventral surfaces of the actin network. These findings reveal how branching events initiate and maintain a network of actin filaments of variable length, and provide the first structural model of the branch junction in vivo. A possible role of filament capping in generating the lamellipodium leaflet is discussed and a mathematical model of protrusion is also presented. acknowledgement: This work was supported by the Austrian Science Fund [projects FWF I516-B09 and FWF P21292-B09 to J.V.S.]; the Vienna Science and Technology Fund [WWTF-grant numbers MA 09-004 to J.V.S. and C.S], ZIT - The Technology Agency of the City of Vienna [VSOE, CMCN to J.V.S. and G.P.R.]; the Deutsche Forschungsgemeinschaft [grant number RO 2414/1-2 to K.R.]; the Daiko research foundation [grant number 9134 to A.N.]; and a Grant-in-Aid for Scientific Research [S, grant number 20227008 to Y.M.] and a Grant-in-Aid for Young Scientists [B, grant number 22770145 to A.N.] (B) from The Ministry of Education, Culture, Sports, Science and Technology of the Japanese Government.

The functionally uncharacterized S. aureus LytR-CpsA-Psr (LCP) proteins, MsrR, SA0908 and SA2103, all belong to the CWSS. Although not essential, deletion of all three LCP proteins severely impairs cell division. We show here that VraSR-dependent CWSS expression was up to 250-fold higher in single, double and triple LCP mutants than in wild type S. aureus in the absence of external stress. The LCP triple mutant was virtually depleted of wall teichoic acids (WTA), which could be restored to different degrees by any of the single LCP proteins. Subinhibitory concentrations of tunicamycin, which inhibits the first WTA synthesis enzyme TarO (TagO), could partially complement the severe growth defect of the LCP triple mutant. Both of the latter findings support a role for S. aureus LCP proteins in late WTA synthesis, as in Bacillus subtilis where LCP proteins were recently proposed to transfer WTA from lipid carriers to the cell wall peptidoglycan. Intrinsic activation of the CWSS upon LCP deletion and the fact that LCP proteins were essential for WTA-loading of the cell wall, highlight their important role(s) in S. aureus cell envelope biogenesis. article_processing_charge: No article_type: original author: - first_name: Vanina full_name: Dengler, Vanina last_name: Dengler - first_name: Patricia Stutzmann full_name: Meier, Patricia Stutzmann last_name: Meier - first_name: Ronald full_name: Heusser, Ronald last_name: Heusser - first_name: Peter full_name: Kupferschmied, Peter last_name: Kupferschmied - first_name: Judit full_name: Fazekas, Judit id: 36432834-F248-11E8-B48F-1D18A9856A87 last_name: Fazekas orcid: 0000-0002-8777-3502 - first_name: Sarah full_name: Friebe, Sarah last_name: Friebe - first_name: Sibylle Burger full_name: Staufer, Sibylle Burger last_name: Staufer - first_name: Paul A. full_name: Majcherczyk, Paul A. last_name: Majcherczyk - first_name: Philippe full_name: Moreillon, Philippe last_name: Moreillon - first_name: Brigitte full_name: Berger-Bächi, Brigitte last_name: Berger-Bächi - first_name: Nadine full_name: McCallum, Nadine last_name: McCallum citation: ama: Dengler V, Meier PS, Heusser R, et al.

To achieve their profound adaptability, plants are able to maintain permanent stem cell populations and form new organs during the entire plant life cycle. Signaling substances, called plant hormones, such as auxin, cytokinin, abscisic acid, brassinosteroid, ethylene, gibberellin, jasmonic acid, and strigolactone, govern and coordinate these developmental processes. Physiological and genetic studies have dissected the molecular components of signal perception and transduction of the individual hormonal pathways. However, over recent years it has become evident that hormones do not act only in a linear pathway. Hormonal pathways are interconnected by a complex network of interactions and feedback circuits that determines the final outcome of the individual hormone actions. This raises questions about the molecular mechanisms underlying hormonal cross talk and about how these hormonal networks are established, maintained, and modulated throughout plant development. acknowledgement: We would like to thank Annick Bleys for help in preparing the manuscript.

The plant hormones auxin and cytokinin are central endogenous signaling molecules that regulate lateral root organogenesis positively and negatively, respectively. Tight control and mutual balance of their antagonistic activities are particularly important during the early phases of lateral root organogenesis to ensure continuous lateral root initiation (LRI) and proper development of lateral root primordia (LRP). Here, we show that the early phases of lateral root organogenesis, including priming and initiation, take place in root zones with a repressed cytokinin response. Accordingly, ectopic overproduction of cytokinin in the root basal meristem most efficiently inhibits LRI. Enhanced cytokinin responses in pericycle cells between existing LRP might restrict LRI near existing LRP and, when compromised, ectopic LRI occurs. Furthermore, our results demonstrate that young LRP are more sensitive to perturbations in the cytokinin activity than are developmentally more advanced primordia. We hypothesize that the effect of cytokinin on the development of primordia possibly depends on the robustness and stability of the auxin gradient. acknowledgement: We thank Jen Sheen, Dolf Weijers, Tatsuo Kakimoto, Stephen Depuydt, and Laurent Laplaze for sharing published material, Jiri Friml for discussions, and Martine De Cock and Annick Bleys for help in preparing the manuscript.
