Two cases of shock propagation are considered: 1)\nthrough a gradient of ambient density with a uniform ambient magnetic field; 2)\nthrough a homogeneous medium with a gradient of ambient magnetic field\nstrength.

Due to the asymmetric topology, the synchronous patterns formed\nin complex networks are irregular and nonstationary. For coupling strength\nimmediately out of the synchronizable region, the typical phenomenon is the\non-off intermittency of the system dynamics. The patterns appeared in this\nprocess are signatured by the coexistence of a giant cluster, which comprises\nmost of the nodes, and a few number of small clusters. The pattern evolution is\ncharacterized by the giant cluster irregularly absorbs or emits the small\nclusters. As the coupling strength leaves away from the synchronization\nbifurcation point, the giant cluster is gradually dissolved into a number of\nsmall clusters, and the system dynamics is characterized by the integration and\nseparation of the small clusters. Dynamical mechanisms and statistical\nproperties of the nonstationary pattern evolution are analyzed and conducted,\nand some scalings are newly revealed. Remarkably, it is found that the few\nactive nodes, which escape from the giant cluster with a high frequency, are\nindependent of the coupling strength while are sensitive to the bifurcation\ntypes.

Rather, we argue that it owes to the fact that\nmore massive systems (i) have more massive progenitors, (ii) assemble later,\nand (iii) have a larger fraction of early-type progenitors. Each of these three\ntrends causes the cold gas mass fraction of the progenitors of more massive\nearly-types to be lower, so that their last major merger was dryer.

They have the potential to efficiently transport angular\nmomentum by MHD turbulence or via the magnetocentrifugal acceleration of\noutflows from the disk surface, and magnetically-driven mixing has implications\nfor disk chemistry and evolution of the grain population. However, the weak\nionisation of protoplanetary discs means that magnetic fields may not be able\nto effectively couple to the matter. I present calculations of the ionisation\nequilibrium and magnetic diffusivity as a function of height from the disk\nmidplane at radii of 1 and 5 AU. Dust grains tend to suppress magnetic coupling\nby soaking up electrons and ions from the gas phase and reducing the\nconductivity of the gas by many orders of magnitude. However, once grains have\ngrown to a few microns in size their effect starts to wane and magnetic fields\ncan begin to couple to the gas even at the disk midplane. Because ions are\ngenerally decoupled from the magnetic field by neutral collisions while\nelectrons are not, the Hall effect tends to dominate the diffusion of the\nmagnetic field when it is able to partially couple to the gas.\n  For a standard population of 0.1 micron grains the active surface layers have\na combined column of about 2 g/cm^2 at 1 AU; by the time grains have aggregated\nto 3 microns the active surface density is 80 g/cm^2. In the absence of grains,\nx-rays maintain magnetic coupling to 10% of the disk material at 1 AU (150\ng/cm^2).

In this paper, we consider whether cosmogenic neutrinos can be a\nclue to judge which scenario is favored. We calculated the fluxes of cosmogenic\nneutrinos following these scenarios with plausible physical parameter sets, and\nfound several important features as follows. First of all, the neutrino flux at\n$\\sim 10^{20}$ eV becomes much higher in the ankle-transition scenario as long\nas the maximum energy of the cosmic rays at sources is sufficiently high. On\nthe other hand, the neutrino spectrum has a characteristic peak at $\\sim\n10^{16}$ eV in the proton-dip scenario on the condition that extragalactic\nprotons significantly contribute to the observed cosmic rays down to $10^{17}$\neV. Thus, we conclude cosmogenic neutrinos should give us a clue to judge which\nscenario is favored, unless these features are masked by the neutrino\nbackground coming from possible, powerful neutrino sources such as AGNs and\nGRBs. We also found an interesting feature that the neutrino flux at $\\sim\n10^{18}$ eV depends only on the cosmological evolution of the cosmic ray\nsources. That means cosmogenic neutrinos with the energy bring us information\non the cosmological evolution of the sources of ultra-high energy cosmic rays.\nFinally, we compare the fluxes of cosmogenic neutrinos with the expected\nsensitivity curves of several neutrino detectors, and conclude the detection of\ncosmogenic neutrinos in the near future is promising.\n', '[{\"version\":\"v1\",\"created\":\"Sat, 7 Apr 2007 10:48:57 GMT\"},{\"version\":\"v2\",\"created\":\"Thu, 15 Jan 2009 15:10:41 GMT\"}]', '2009-06-23', '[[\"Takami\",\"Hajime\",\"\"],[\"Murase\",\"Kohta\",\"\"],[\"Nagataki\",\"Shigehiro\",\"\"],[\"Sato\",\"Katsuhiko\",\"\"]]'),
