    Random walks on Galton-Watson trees with infinite variance offspring distribution conditioned to survive

    No full text
    We establish a variety of properties of the discrete time simple random walk on a Galton-Watson tree conditioned to survive when the offspring distribution, Z say, is in the domain of attraction of a stable law with index alpha is an element of (1,2]. In particular, we are able to prove a quenched version of the result that the spectral dimension of the random walk is 2 alpha/(2 alpha-1). Furthermore, we demonstrate that when alpha is an element of (1,2) there are logarithmic fluctuations in the quenched transition density of the simple random walk, which contrasts with the log-logarithmic fluctuations seen when alpha=2. In the course of our arguments, we obtain tail bounds for the distribution of the nth generation size of a Galton-Watson branching process with offspring distribution Z conditioned to survive, as well as tail bounds for the distribution of the total number of individuals born up to the nth generation, that are uniform in n

    Measurement of the ttˉZt\bar{t}Z and ttˉWt\bar{t}W production cross sections in multilepton final states using 3.2 fb1^{-1} of pppp collisions at s\sqrt{s} = 13 TeV with the ATLAS detector

All figures including auxiliary figures are available at http://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/PAPERS/TOPQ-2015-22/International audienceA measurement of the ttˉZt\bar{t}Z and ttˉWt\bar{t}W production cross sections in final states with either two same-charge muons, or three or four leptons (electrons or muons) is presented. The analysis uses a data sample of proton-proton collisions at s=13\sqrt{s} = 13 TeV recorded with the ATLAS detector at the Large Hadron Collider in 2015, corresponding to a total integrated luminosity of 3.2 fb1^{-1}. The inclusive cross sections are extracted using likelihood fits to signal and control regions, resulting in σttˉZ=0.9±0.3\sigma_{t\bar{t}Z} = 0.9 \pm 0.3 pb and σttˉW=1.5±0.8\sigma_{t\bar{t}W} = 1.5 \pm 0.8 pb, in agreement with the Standard Model predictions

    Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.

    IFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells

    Excavation at Aguas Buenas, Robinson Crusoe Island, Chile, of a gunpowder magazine and the supposed campsite of Alexander Selkirk, together with an account of early navigational dividers

    No full text
    Excavations were undertaken of a ruined building at Aguas Buenas, identified as an 18th-century Spanish gunpowder magazine. Evidence was also found for the campsite of an early European occupant of the island. A case is made that this was Alexander Selkirk, a castaway here from 1704 to 1709. Selkirk was the model for Defoe’s Robinson Crusoe. A detailed discussion is given of a fragment of copper alloy identifi ed as being from a pair of navigational dividers

    Evolution of a topos of Russia-home in ‘the Red Wheel’ by Alexander Solzhenitsyn

    No full text
    The paper depicts a topos of Russia-home in Alexander Solzhenitsyn’s novel cycle the ‘Red Wheel’. The author defines metaphoric pictures named as a home, an empty house, a house without an owner. The metaphors allows to indicate additional motifs connected with titular topos: a good host, a woman as a wife and mother and a fake host. The analyses show that Solzhenitsyn’s metaphors of Russia-home reflect writer’s conception of the revolutionary process in the history of Russia and his thoughts about citizen responsibility and [email protected] Uniwersytet Lubelski Jana Pawła II, Wydział Nauk Humanistycznych, Katedra Literatury Rosyjskiej, Ukraińskiej i BiałoruskiejBachtin M., 1982, Formy czasu i czasoprzestrzeni w powieści.
