--- _id: '6987' abstract: - lang: eng text: Cells are arranged into species-specific patterns during early embryogenesis. Such cell division patterns are important since they often reflect the distribution of localized cortical factors from eggs/fertilized eggs to specific cells as well as the emergence of organismal form. However, it has proven difficult to reveal the mechanisms that underlie the emergence of cell positioning patterns that underlie embryonic shape, likely because a systems-level approach is required that integrates cell biological, genetic, developmental, and mechanical parameters. The choice of organism to address such questions is also important. Because ascidians display the most extreme form of invariant cleavage pattern among the metazoans, we have been analyzing the cell biological mechanisms that underpin three aspects of cell division (unequal cell division (UCD), oriented cell division (OCD), and asynchronous cell cycles) which affect the overall shape of the blastula-stage ascidian embryo composed of 64 cells. In ascidians, UCD creates two small cells at the 16-cell stage that in turn undergo two further successive rounds of UCD. Starting at the 16-cell stage, the cell cycle becomes asynchronous, whereby the vegetal half divides before the animal half, thus creating 24-, 32-, 44-, and then 64-cell stages. Perturbing either UCD or the alternate cell division rhythm perturbs cell position. We propose that dynamic cell shape changes propagate throughout the embryo via cell-cell contacts to create the ascidian-specific invariant cleavage pattern. alternative_title: - RESULTS article_processing_charge: No author: - first_name: Alex full_name: McDougall, Alex last_name: McDougall - first_name: Janet full_name: Chenevert, Janet last_name: Chenevert - first_name: Benoit G full_name: Godard, Benoit G id: 33280250-F248-11E8-B48F-1D18A9856A87 last_name: Godard - first_name: Remi full_name: Dumollard, Remi last_name: Dumollard citation: ama: 'McDougall A, Chenevert J, Godard BG, Dumollard R.

We use this connection to show that certain modular functions, when restricted to the hyperelliptic locus, assume values whose denominators are products of powers of primes of bad reduction for the associated hyperelliptic curves. We illustrate our theorem with explicit computations. This work is motivated by the study of the values of these modular functions at CM points of the Siegel upper half-space, which, if their denominators are known, can be used to effectively compute models of (hyperelliptic, in our case) curves with CM. acknowledgement: "The authors would like to thank the Lorentz Center in Leiden for hosting the Women in Numbers Europe 2 workshop and providing a productive and enjoyable environment for our initial work on this project.

However, recent evidence suggests that the leading edge may be dispensable for migration, raising the question of what actually controls cell directionality. Here, we exploit the embryonic migration of Drosophila macrophages to bridge the different temporal scales of the behaviours controlling motility. This approach reveals that edge fluctuations during random motility are not persistent and are weakly correlated with motion. In contrast, flow of the actin network behind the leading edge is highly persistent. Quantification of actin flow structure during migration reveals a stable organization and asymmetry in the cell-wide flowfield that strongly correlates with cell directionality. This organization is regulated by a gradient of actin network compression and destruction, which is controlled by myosin contraction and cofilin-mediated disassembly. It is this stable actin-flow polarity, which integrates rapid fluctuations of the leading edge, that controls inherent cellular persistence. article_processing_charge: No article_type: original author: - first_name: Lawrence full_name: Yolland, Lawrence last_name: Yolland - first_name: Mubarik full_name: Burki, Mubarik last_name: Burki - first_name: Stefania full_name: Marcotti, Stefania last_name: Marcotti - first_name: Andrei full_name: Luchici, Andrei last_name: Luchici - first_name: Fiona N. full_name: Kenny, Fiona N. last_name: Kenny - first_name: John Robert full_name: Davis, John Robert last_name: Davis - first_name: Eduardo full_name: Serna-Morales, Eduardo last_name: Serna-Morales - first_name: Jan full_name: Müller, Jan id: AD07FDB4-0F61-11EA-8158-C4CC64CEAA8D last_name: Müller - first_name: Michael K full_name: Sixt, Michael K id: 41E9FBEA-F248-11E8-B48F-1D18A9856A87 last_name: Sixt orcid: 0000-0002-6620-9179 - first_name: Andrew full_name: Davidson, Andrew last_name: Davidson - first_name: Will full_name: Wood, Will last_name: Wood - first_name: Linus J. full_name: Schumacher, Linus J. last_name: Schumacher - first_name: Robert G. full_name: Endres, Robert G. last_name: Endres - first_name: Mark full_name: Miodownik, Mark last_name: Miodownik - first_name: Brian M. full_name: Stramer, Brian M. last_name: Stramer citation: ama: Yolland L, Burki M, Marcotti S, et al.

A temporal tester is a transducer that inputs a signal holding the Boolean value of atomic propositions and outputs the truth value of a formula along time. Here we consider testers over continuous-time Boolean signals that use clock variables to enforce duration constraints, as in timed automata. We first rewrite the MITL formula into a “simple” formula using a limited set of temporal modalities. We then build testers for these specific modalities and show how to compose testers for simple formulae into complex ones. Temporal testers can be turned into acceptors, yielding a compositional translation from MITL to timed automata. This construction is much simpler than previously known and remains asymptotically optimal. It supports both past and future operators and can easily be extended. article_number: '19' article_processing_charge: No article_type: original author: - first_name: Thomas full_name: Ferrere, Thomas id: 40960E6E-F248-11E8-B48F-1D18A9856A87 last_name: Ferrere orcid: 0000-0001-5199-3143 - first_name: Oded full_name: Maler, Oded last_name: Maler - first_name: Dejan full_name: Ničković, Dejan last_name: Ničković - first_name: Amir full_name: Pnueli, Amir last_name: Pnueli citation: ama: Ferrere T, Maler O, Ničković D, Pnueli A.

For d ≥ 3, both problems remain NP-hard when restricted to contractible pure d-dimensional complexes.

If the transcription factors are not affected by gene products, the regulating function is often represented as a combinational logic circuit, where the outputs (product) are determined by current input values (transcription factors) only, and are hence independent on their relative arrival times. However, the simultaneous arrival of transcription factors (TFs) in genetic circuits is a strong assumption, given that the processes of transcription and translation of a gene into a protein introduce intrinsic time delays and that there is no global synchronisation among the arrival times of different molecular species at molecular targets.\r\n\r\nIn this paper, we construct an experimentally implementable genetic circuit with two inputs and a single output, such that, in presence of small delays in input arrival, the circuit exhibits qualitatively distinct observable phenotypes. In particular, these phenotypes are long lived transients: they all converge to a single value, but so slowly, that they seem stable for an extended time period, longer than typical experiment duration. We used rule-based language to prototype our circuit, and we implemented a search for finding the parameter combinations raising the phenotypes of interest.\r\n\r\nThe behaviour of our prototype circuit has wide implications. First, it suggests that GRNs can exploit event timing to create phenotypes. Second, it opens the possibility that GRNs are using event timing to react to stimuli and memorise events, without explicit feedback in regulation. From the modelling perspective, our prototype circuit demonstrates the critical importance of analysing the transient dynamics at the promoter binding sites of the DNA, before applying rapid equilibrium assumptions." alternative_title: - LNCS article_processing_charge: No author: - first_name: Calin C full_name: Guet, Calin C id: 47F8433E-F248-11E8-B48F-1D18A9856A87 last_name: Guet orcid: 0000-0001-6220-2052 - first_name: Thomas A full_name: Henzinger, Thomas A id: 40876CD8-F248-11E8-B48F-1D18A9856A87 last_name: Henzinger orcid: 0000−0002−2985−7724 - first_name: Claudia full_name: Igler, Claudia id: 46613666-F248-11E8-B48F-1D18A9856A87 last_name: Igler - first_name: Tatjana full_name: Petrov, Tatjana id: 3D5811FC-F248-11E8-B48F-1D18A9856A87 last_name: Petrov orcid: 0000-0002-9041-0905 - first_name: Ali full_name: Sezgin, Ali id: 4C7638DA-F248-11E8-B48F-1D18A9856A87 last_name: Sezgin citation: ama: 'Guet CC, Henzinger TA, Igler C, Petrov T, Sezgin A.
