Currently, ecological models can only explain such limits if patches vary in quality, leading to asymmetrical dispersal, or if genetic variation is too low at the margins for adaptation. However, population genetic models suggest that the increase in genetic variance resulting from dispersal should allow adaptation to almost any ecological gradient. Clearly therefore, these models miss something that prevents evolution in natural populations. We developed an individual-based simulation to explore stochastic effects in these models. At high carrying capacities, our simulations largely agree with deterministic predictions. However, when carrying capacity is low, the population fails to establish for a wide range of parameter values where adaptation was expected from previous models. Stochastic or transient effects appear critical around the boundaries in parameter space between simulation behaviours. Dispersal, gradient steepness, and population density emerge as key factors determining adaptation on an ecological gradient.

Mechanical forces probably participate in this process but how they influence organ morphogenesis is still unclear. Here, we show that Wnt11- and Prickle1a-mediated planar cell polarity (PCP) signalling coordinates the formation of the zebrafish ciliated laterality organ (Kupffer's vesicle) by regulating adhesion properties between organ progenitor cells (the dorsal forerunner cells, DFCs). Combined inhibition of Wnt11 and Prickle1a reduces DFC cell-cell adhesion and impairs their compaction and arrangement during vesicle lumen formation. This leads to the formation of a mis-shapen vesicle with small fragmented lumina and shortened cilia, resulting in severely impaired organ function and, as a consequence, randomised laterality of both molecular and visceral asymmetries. Our results reveal a novel role for PCP-dependent cell adhesion in coordinating the supracellular organisation of progenitor cells during vertebrate laterality organ formation."}],"extern":"1","date_updated":"2021-01-12T07:54:58Z","intvolume":"       137","publist_id":"1958","year":"2010","language":[{"iso":"eng"}],"publisher":"Company of Biologists","type":"journal_article","date_published":"2010-10-15T00:00:00Z"},{"year":"2010","publisher":"Nature Publishing Group","type":"journal_article","date_published":"2010-01-01T00:00:00Z","publist_id":"1932","extern":1,"date_updated":"2021-01-12T07:55:09Z","intvolume":"        12","citation":{"chicago":"Kardash, Elena, Michal Reichman Fried, Jean Maître, Bijan Boldajipour, Ekaterina Papusheva, Esther Messerschmidt, Carl Heisenberg, and Erez Raz. “A Role for Rho GTPases and Cell-Cell Adhesion in Single-Cell Motility in Vivo.” <i>Nature Cell Biology</i>.

Whereas the mechanisms controlling single-cell migration in vitro are relatively well understood(2-4), less is known about the mechanisms promoting the motility of individual cells in vivo. In particular, it is not clear how cells that form blebs in their migration use those protrusions to bring about movement in the context of the three-dimensional cellular environment(5,6). Here we show that the motility of chemokine-guided germ cells within the zebrafish embryo requires the function of the small Rho GTPases Rac1 and RhoA, as well as E-cadherin-mediated cell-cell adhesion. Using fluorescence resonance energy transfer we demonstrate that Rac1 and RhoA are activated in the cell front. At this location, Rac1 is responsible for the formation of actin-rich structures, and RhoA promotes retrograde actin flow. We propose that these actin-rich structures undergoing retrograde flow are essential for the generation of E-cadherin-mediated traction forces between the germ cells and the surrounding tissue and are therefore crucial for cell motility in vivo.","lang":"eng"}],"date_created":"2018-12-11T12:07:28Z","issue":"1","status":"public","month":"01","author":[{"last_name":"Kardash","first_name":"Elena","full_name":"Kardash, Elena"},{"first_name":"Michal","full_name":"Reichman-Fried, Michal","last_name":"Reichman Fried"},{"full_name":"Maître, Jean-Léon","first_name":"Jean","last_name":"Maître"},{"full_name":"Boldajipour, Bijan","first_name":"Bijan","last_name":"Boldajipour"},{"last_name":"Papusheva","first_name":"Ekaterina","full_name":"Ekaterina Papusheva","id":"41DB591E-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Messerschmidt","first_name":"Esther","full_name":"Messerschmidt, Esther-Maria"},{"last_name":"Heisenberg","full_name":"Heisenberg, Carl-Philipp","first_name":"Carl"},{"last_name":"Raz","first_name":"Erez","full_name":"Raz, Erez"}],"title":"A role for Rho GTPases and cell-cell adhesion in single-cell motility in vivo","_id":"4187","quality_controlled":0,"publication":"Nature Cell Biology","doi":"10.1038/ncb2003","publication_status":"published","day":"01","fulldoi":"https://doi.org/10.1038/ncb2003"},{"abstract":[{"lang":"eng","text":"Collective cell migration, the simultaneous movement of multiple cells that are connected by cell-cell adhesion, is ubiquitous in development, tissue repair, and tumor metastasis [1, 2].

Here we determine how movement directionality is established in collective mesendoderm migration during zebrafish gastrulation. By interfering with two key features of collective migration, (1) having neighboring cells and (2) adhering to them, we show that individual mesendoderm cells are capable of normal directed migration when moving as single cells but require cell-cell adhesion to participate in coordinated and directed migration when moving as part of a group.

This model can be thought of as a spatial version of the Lambda-Fleming-Viot process. It explicitly incorporates both small scale reproduction events and large scale extinction-recolonisation events.

Using a technique of Evans (1997), we prove existence and uniqueness in law for the model. We then investigate the asymptotic behaviour of the genealogy of a finite number of individuals sampled uniformly at random (or more generally `far enough apart') from a two-dimensional torus of sidelength L as L tends to infinity. Under appropriate conditions (and on a suitable timescale) we can obtain as limiting genealogical processes a Kingman coalescent, a more general Lambda-coalescent or a system of coalescing Brownian motions (with a non-local coalescence mechanism).","lang":"eng"}],"pubrep_id":"369","page":"162 - 216","volume":15,"type":"journal_article","publisher":"Institute of Mathematical Statistics","language":[{"iso":"eng"}],"year":"2010","publist_id":"1863","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","doi":"10.1214/EJP.v15-741","license":"https://creativecommons.org/licenses/by/4.0/","day":"03","author":[{"first_name":"Nicholas H","id":"4880FE40-F248-11E8-B48F-1D18A9856A87","full_name":"Barton, Nicholas H","orcid":"0000-0002-8548-5240","last_name":"Barton"},{"first_name":"Alison","full_name":"Etheridge, Alison","last_name":"Etheridge"},{"last_name":"Véber","first_name":"Amandine","full_name":"Véber, Amandine"}],"ddc":["576"],"status":"public","isi":1,"month":"02","issue":"7","publication":"Electronic Journal of Probability","quality_controlled":"1","scopus_import":"1","citation":{"ama":"Barton NH, Etheridge A, Véber A.

An example is Sonic hedgehog (Shh), which acts in several developing vertebrate tissues, including the central nervous system, to provide positional information during embryonic patterning. Here we address how Shh signalling assigns the positional identities of distinct neuronal subtype progenitors throughout the ventral neural tube. Assays of intracellular signal transduction and gene expression indicate that the duration as well as level of signalling is critical for morphogen interpretation. Progenitors of the ventral neuronal subtypes are established sequentially, with progressively more ventral identities requiring correspondingly higher levels and longer periods of Shh signalling. Moreover, cells remain sensitive to changes in Shh signalling for an extended time, reverting to antecedent identities if signalling levels fall below a threshold. Thus, the duration of signalling is important not only for the assignment but also for the refinement and maintenance of positional identity. Together the data suggest a dynamic model for ventral neural tube patterning in which positional information corresponds to the time integral of Shh signalling. This suggests an alternative to conventional models of morphogen action that rely solely on the level of signalling.","lang":"eng"}],"extern":1,"intvolume":"         8","date_updated":"2021-01-12T06:52:46Z","publist_id":"5408","year":"2010","acknowledgement":"NS was supported by a Marie Curie Fellowship (PIIF-GA-2008-219939) and the Mochida Memorial Foundation for Medical and Pharmaceutical Research.

The nanowires are grown by catalyst-free, plasma-assisted molecular beam epitaxy enabling abrupt GaN/AlN interfaces as well as longitudinal n-type doping modulation. At low temperature, transport in n-i-n GaN nanowires is dominated by the Coulomb blockade effect. Carriers are confined in the undoped middle region, forming single or multiple islands with a characteristic length of ∼100 nm. The incorporation of two AlN tunnel barriers causes confinement to occur within the GaN dot in between. In the case of a 6 nm thick dot and 2 nm thick barriers, we observe characteristic signatures of Coulomb-blockaded transport in single quantum dots with discrete energy states. For thinner dots and barriers, Coulomb-blockade effects do not play a significant role while the onset of resonant tunneling via the confined quantum levels is accompanied by a negative differential resistance surviving up to ∼150 K.","lang":"eng"}],"citation":{"mla":"Songmuang, Rudeeson, et al. “Quantum Transport in GaN/AlN Double-Barrier Heterostructure Nanowires.” <i>Nano Letters</i>, vol. 10, no. 9, American Chemical Society, 2010, pp. 3545–50, doi:<a href=\"https://doi.org/10.1021/nl1017578\">10.1021/nl1017578</a>.","apa":"Songmuang, R., Katsaros, G., Monroy, E., Spathis, P., Bougerol, C., Mongillo, M., &#38; De Franceschi, S.

This requires the gas to avoid cooling and to remain at temperatures near T=10^4 K. We show that this condition can be satisfied in the presence of a sufficiently strong primordial magnetic field, which heats the collapsing gas via ambipolar diffusion. If the field has a strength above B = 3.6 (comoving) nG, the collapsing gas is kept warm (T=10^4K) until it reaches the critical density n_crit=10^3 cm^{-3} at which the roto-vibrational states of H_2 approach local thermodynamic equilibrium. H_2-cooling then remains inefficient, and the gas temperature stays near 10^4K, even as it continues to collapse to higher densities. The critical magnetic field strength required to permanently suppress H_2-cooling is somewhat higher than upper limit of approx. 2 nG from the cosmic microwave background (CMB). However, it can be realized in the rare (2-3)-sigma regions of the spatially fluctuating B-field; these regions contain a sufficient number of halos to account for the z=6 quasar BHs.","lang":"eng"}],"language":[{"iso":"eng"}],"year":"2010","type":"journal_article","publisher":"American Astronomical Society","oa":1,"article_processing_charge":"No","publication_status":"published","fulldoi":"https://doi.org/10.1088/0004-637x/721/1/615","oa_version":"Published Version","date_created":"2024-09-06T07:16:56Z","publication_identifier":{"issn":["0004-637X","1538-4357"]},"_id":"17639","title":"Supermassive black hole formation at high redshifts through a primordial magnetic field"},{"fulldoi":"https://doi.org/10.1111/j.1365-2966.2009.15960.x","oa_version":"Published Version","publication_status":"published","article_processing_charge":"No","oa":1,"_id":"17648","title":"Supermassive black hole formation by direct collapse: keeping protogalactic gas H2 free in dark matter haloes with virial temperatures T_vir > rsim10^4 K ","publication_identifier":{"issn":["0035-8711","1365-2966"]},"date_created":"2024-09-06T07:26:50Z","abstract":[{"text":"In the absence of H_2 molecules, the primordial gas in early dark matter halos with virial temperatures just above T_vir >~ 10^4 K cools by collisional excitation of atomic H. Although it cools efficiently, this gas remains relatively hot, at a temperature near T ~ 8000 K, and consequently might be able to avoid fragmentation and collapse directly into a supermassive black hole (SMBH). In order for H_2--formation and cooling to be strongly suppressed, the gas must be irradiated by a sufficiently intense ultraviolet (UV) flux. We performed a suite of three--dimensional hydrodynamical adaptive mesh refinement (AMR) simulations of gas collapse in three different protogalactic halos with T_vir >~ 10^4 K, irradiated by a UV flux with various intensities and spectra. We determined the critical specific intensity, Jcrit, required to suppress H_2 cooling in each of the three halos. For a hard spectrum representative of metal--free stars, we find (in units of 10^{-21} erg s^{-1} Hz^{-1} sr^{-1} cm^{-2}) 10^4<Jcrit<10^5, while for a softer spectrum, which is characteristic of a normal stellar population, and for which H^{-} --dissociation is important, we find 30<Jcrit<300. These values are a factor of 3--10 lower than previous estimates. We attribute the difference to the higher, more accurate H_2 collisional dissociation rate we adopted. The reduction in Jcrit exponentially increases the number of rare halos exposed to super--critical radiation. When H_2 cooling is suppressed, gas collapse starts with a delay, but it ultimately proceeds more rapidly. The infall velocity is near the increased sound speed, and an object as massive as M ~ 10^5 solar mass may form at the center of these halos, compared to the M ~ 10^2 solar mass stars forming when H_2--cooling is efficient.","lang":"eng"}],"page":"1249-1262","volume":402,"date_updated":"2024-09-24T12:49:06Z","intvolume":"       402","extern":"1","type":"journal_article","publisher":"Oxford University Press","language":[{"iso":"eng"}],"year":"2010","article_type":"original","day":"02","doi":"10.1111/j.1365-2966.2009.15960.x","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","publication":"Monthly Notices of the Royal Astronomical Society","quality_controlled":"1","author":[{"last_name":"Shang","full_name":"Shang, Cien","first_name":"Cien"},{"last_name":"Bryan","full_name":"Bryan, Greg L.","first_name":"Greg L."},{"first_name":"Zoltán","full_name":"Haiman, Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","last_name":"Haiman"}],"month":"02","status":"public","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1111/j.1365-2966.2009.15960.x"}],"issue":"2","citation":{"chicago":"Shang, Cien, Greg L.

A promising possibility, in the case of the coalescence of a supermassive black hole binary (SMBHB), is that the prompt emission from merger-induced disturbances in a supersonic circumbinary disc may be detectable. We follow the post-merger evolution of a thin, zero-viscosity circumbinary gas disc with two-dimensional simulations, using the hydrodynamic code flash. We analyse perturbations arising from the 530 km s−1 recoil of a 106 M⊙ binary, oriented in the plane of the disc, assuming either a non-radiative gamma-law or a pseudo-isothermal equation of state for the gas. We find that a single-armed spiral shock wave forms and propagates outwards, sweeping up ∼40 per cent of the mass of the disc. The morphology and evolution of the perturbations agrees well with those of caustics predicted to occur in a collisionless disc. Assuming that the disc radiates nearly instantaneously to maintain a constant temperature, we estimate the amount of dissipation and corresponding post-merger light curve. The luminosity rises steadily on the time-scale of months, and reaches few ×1043 erg s−1, corresponding to ≈10 per cent of the Eddington luminosity of the central SMBHB. We also analyse the case in which gravitational wave emission results in a 5 per cent mass loss in the merger remnant. The mass loss reduces the shock overdensities and the overall luminosity of the disc by ≈15–20 per cent, without any other major effects on the spiral shock pattern.","lang":"eng"}],"year":"2010","language":[{"iso":"eng"}],"publisher":"Oxford University Press","type":"journal_article","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","doi":"10.1111/j.1365-2966.2010.16324.x","alternative_title":["Gas disc response to black hole merger"],"day":"04","article_type":"original","issue":"2","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1111/j.1365-2966.2010.16324.x"}],"status":"public","month":"05","author":[{"last_name":"Corrales","full_name":"Corrales, Lia R.","first_name":"Lia R."},{"full_name":"Haiman, Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","first_name":"Zoltán","last_name":"Haiman"},{"last_name":"MacFadyen","full_name":"MacFadyen, Andrew","first_name":"Andrew"}],"quality_controlled":"1","publication":"Monthly Notices of the Royal Astronomical Society","scopus_import":"1","citation":{"short":"L.R.

It has been proposed that once the merger has been detected in gravitational waves (GWs) by LISA, follow-up EM searches for this afterglow can help identify the EM counterpart of the LISA source. Here we study whether the afterglows may be sufficiently bright and numerous to be detectable in EM surveys alone. The viscous afterglow, which lasts for years to decades for SMBHBs in LISA's sensitivity window, is characterized by rapid increases in both the bolometric luminosity and in the spectral hardness of the source. If quasar activity is triggered by the same major galaxy mergers that produce SMBHBs, then the afterglow could be interpreted as a signature of the birth of a quasar. Using an idealized model for the post-merger viscous spreading of the circumbinary disk and the resulting light curve, and using the observed luminosity function of quasars as a proxy for the SMBHB merger rate, we delineate the survey requirements for identifying such birthing quasars. If circumbinary disks have a high disk surface density and viscosity, an all-sky soft X-ray survey with a sensitivity of ~<3x10^-14 erg s^-1 cm^-2 and a time resolution of ~months could identify dozens of birthing quasars with sustained brightening rates of >10%/yr. If >1% of the X-ray emission is reprocessed into optical frequencies, birthing quasars could also be identified in optical transient surveys such as the LSST. Distinguishing a birthing quasar from other variable sources may be facilitated by the monotonic hardening of its spectrum, but will likely remain challenging. This reinforces the notion that joint EM-plus-GW observations offer the best prospects for identifying the EM signatures of SMBHB mergers.","lang":"eng"}],"year":"2010","language":[{"iso":"eng"}],"publisher":"American Astronomical Society","type":"journal_article"},{"citation":{"chicago":"Molnar, Sandor M., Keiichi Umetsu, Mark Birkinshaw, Greg Bryan, Zoltán Haiman, Nathan Hearn, Cien Shang, et al. “Constraining Intracluster Gas Models with AMiBA13.” <i>The Astrophysical Journal</i>.

A major difficulty in making the best use of Sunyaev–Zel'dovich (SZ) and X-ray observations of clusters for cosmology is that using X-ray observations it is difficult to measure the temperature distribution and therefore determine the density distribution in individual clusters of galaxies out to the virial radius. Observations with the new generation of SZ instruments are a promising alternative approach. We use clusters of galaxies drawn from high-resolution adaptive mesh refinement cosmological simulations to study how well we should be able to constrain the large-scale distribution of the intracluster gas (ICG) in individual massive relaxed clusters using AMiBA in its configuration with 13 1.2 m diameter dishes (AMiBA13) along with X-ray observations. We show that non-isothermal β models provide a good description of the ICG in our simulated relaxed clusters. We use simulated X-ray observations to estimate the quality of constraints on the distribution of gas density, and simulated SZ visibilities (AMiBA13 observations) for constraints on the large-scale temperature distribution of the ICG. We find that AMiBA13 visibilities should constrain the scale radius of the temperature distribution to about 50% accuracy. We conclude that the upgraded AMiBA, AMiBA13, should be a powerful instrument to constrain the large-scale distribution of the ICG."}],"extern":"1","date_updated":"2024-09-25T10:08:14Z","intvolume":"       723","year":"2010","language":[{"iso":"eng"}],"publisher":"American Astronomical Society","type":"journal_article","publication_status":"published","oa_version":"Published Version","fulldoi":"https://doi.org/10.1088/0004-637x/723/2/1272","oa":1,"article_processing_charge":"No","title":"Constraining intracluster gas models with AMiBA13","_id":"17695","date_created":"2024-09-06T08:41:14Z","publication_identifier":{"issn":["0004-637X","1538-4357"]}},{"language":[{"iso":"eng"}],"year":"2010","type":"journal_article","publisher":"American Physical Society","article_number":"043519","volume":81,"abstract":[{"lang":"eng","text":"We propose counting peaks in weak lensing (WL) maps, as a function of their height, to probe models of dark energy and to constrain cosmological parameters. Because peaks can be identified in two-dimensional WL maps directly, they can provide constraints that are free from potential selection effects and biases involved in identifying and determining the masses of galaxy clusters. We have run cosmological N-body simulations to produce WL convergence maps in three models with different constant values of the dark energy equation of state parameter, w=-0.8, -1, and -1.2, with a fixed normalization of the primordial power spectrum (corresponding to present-day normalizations of sigma8=0.742, 0.798, and 0.839, respectively). By comparing the number of WL peaks in 8 convergence bins in the range of -0.1 < kappa < 0.2, in multiple realizations of a single simulated 3x3 degree field, we show that the first (last) pair of models can be distinguished at the 95% (85%) confidence level. A survey with depth and area (20,000 sq. degrees), comparable to those expected from LSST, should have a factor of approx. 50 better parameter sensitivity. We find that relatively low-amplitude peaks (kappa = 0.03), which typically do not correspond to a single collapsed halo along the line of sight, account for most of this sensitivity. We study a range of smoothing scales and source galaxy redshifts (z_s). With a fixed source galaxy density of 15/arcmin^2, the best results are provided by the smallest scale we can reliably simulate, 1 arcminute, and z_s=2 provides substantially better sensitivity than z_s< 1.5."}],"arxiv":1,"extern":"1","date_updated":"2024-09-25T11:14:37Z","intvolume":"        81","_id":"17697","title":"Probing cosmology with weak lensing peak counts","date_created":"2024-09-06T08:43:22Z","publication_identifier":{"issn":["1550-7998","1550-2368"]},"publication_status":"published","fulldoi":"https://doi.org/10.1103/physrevd.81.043519","oa_version":"Preprint","oa":1,"article_processing_charge":"No","external_id":{"arxiv":["0907.0486"]},"date_published":"2010-02-10T00:00:00Z","citation":{"ama":"Kratochvil JM, Haiman Z, May M.
