Its measurement is difficult in field\nconditions. Vibration-induced conductivity fluctuation was investigated to\nquantify soil bulk density with possible field applications in the future. The\nAC electrical conductivity of soil was measured using a pair of blade-like\nelectrodes while exposing the soil to periodic vibration. The blades were\npositioned longitudinally and transversally to the direction of the induced\nvibration to enable the calculation of a normalized index. The normalized index\nwas expected to provide data independent from the vibration strength and to\nreduce the effect of soil salinity and water content. The experiment was\nconducted on natural and salinized fine sand at two moisture conditions and\nfour bulk densities. The blade-shaped electrodes improved electrode-soil\ncontact compared to cylindrical electrodes, and thereby, reduced measurement\nnoise. Simulations on a simplified resistor lattice indicate that the\ntransversal effect increases as soil bulk density decreases. Measurement of dry\nsand showed a negative correlation between the normalized conductivity\nfluctuation and soil bulk density for both longitudinal and transversal\nsettings. The decrease in the transversal signal was smaller than expected. The\nwet natural and salinized soils performed very similarly as hypothesized, but\ntheir normalized VICOF response was not significant to bulk density changes.\n', '[{\"version\":\"v1\",\"created\":\"Thu, 3 May 2007 17:20:38 GMT\"}]', '2009-11-13', '[[\"Kishne\",\"Andrea Sz.\",\"\"],[\"Morgan\",\"Cristine L.

A\ncompressive wave is set up in a constant sub-Jeans density distribution of\nradius r = 1 pc. As the wave travels through the simulation grid, a\nshock-bounded spherical shell is formed. The inner shock of this shell reaches\nand bounces off the center, leaving behind a central core with an initially\nalmost uniform density distribution, surrounded by an envelope consisting of\nthe material in the shock-bounded shell, with a power-law density profile that\nat late times approaches a logarithmic slope of -2 even in non-collapsing\ncases. The resulting density structure resembles a quiescent core of radius <\n0.1 pc, with a Bonnor-Ebert-like (BE-like) profile, although it has significant\ndynamical differences: it is initially non-self-gravitating and confined by the\nram pressure of the infalling material, and consequently, growing continuously\nin mass and size. With the appropriate parameters, the core mass eventually\nreaches an effective Jeans mass, at which time the core begins to collapse.\nThus, there is necessarily a time delay between the appearance of the core and\nthe onset of its collapse, but this is not due to the dissipation of its\ninternal turbulence as it is often believed.

Emphasising that complex\nlens potentials can be constructed from simpler components in linear\ncombination, we provide a recipe for attaining elliptical symmetry in either\nprojected mass or lens potential. We also provide analytic formulae for the\nlens potentials of Sersic profiles for integer and half-integer index. We then\npresent formulae describing the gravitational lensing effects due to\nsmoothly-truncated universal density profiles in cold dark matter model. For\nour isolated haloes the density profile falls off as radius to the minus fifth\nor seventh power beyond the tidal radius, functional forms that allow all\norders of lens potential derivatives to be calculated analytically, while\nensuring a non-divergent total mass. We show how the observables predicted by\nthis profile differ from that of the original infinite-mass NFW profile.\nExpressions for the gravitational flexion are highlighted.

These factors have impeded\ndynamical investigations within tens of AU of high-mass YSOs--scales that are\ncritical for probing the interfaces where outflows from accretion disks are\nlaunched and collimated. Using observations of SiO masers obtained with the VLA\nand the VLBA, the KaLYPSO project is overcoming these limitations by mapping\nthe structure and dynamical/temporal evolution of the material 10-1000 AU from\nthe nearest high-mass YSO: Radio Source I in the Orion BN/KL region. Our data\ninclude ~40 epochs of VLBA observations over a several-year period, allowing us\nto track the proper motions of individual SiO maser spots and to monitor\nchanges in the physical conditions of the emitting material with time.\nUltimately these data will provide 3-D maps of the outflow structure over\napproximately 30% of the outflow crossing time. Here we summarize recent\nresults from the KaLYPSO project, including evidence that high-mass star\nformation is occurring via disk-mediated accretion.\n', '[{\"version\":\"v1\",\"created\":\"Fri, 4 May 2007 20:05:43 GMT\"}]', '2009-11-13', '[[\"Matthews\",\"L.

These fallback\nblack-hole GRBs have been recently been argued as possible progenitors of a\nnewly discovered set of GRBs lacking any associated supernovae. Here we present\nthe first ever radiation-hydrodynamics calculations of the light-curves\nproduced in the hypernova explosion by a delayed-fallback gamma-ray burst. We\nfind that the bolometric light-curve is dominated by shock-deposited energy,\nnot the decay of radioactive elements. As such, observations of such bursts\nactually probe the density in the progenitor wind more than it does the\nproduction of radioactive nickel.\n', '[{\"version\":\"v1\",\"created\":\"Fri, 4 May 2007 22:55:27 GMT\"}]', '2009-11-13', '[[\"Fryer\",\"Chris L.\",\"\",\"LANL/UA\"],[\"Hungerford\",\"Aimee L.\",\"\",\"LANL\"],[\"Young\",\"Patrick A.\",\"\",\"LANL/UA\"]]'),
