It also controls the\necliptic latitude at which the Moon crosses the magnetotail and thus the number\nand duration of lunar encounters with the plasmasheet. This paper presents a\ndetailed model of those encounters and applies it to the period 1960 to 2030.\nThis shows that the total lunar exposure to the plasmasheet will vary from 10\nhours per month at a minimum of the eighteen-year cycle rising to 40 hours per\nmonth at the maximum. These variations could have a profound impact on the\naccumulation of charge due plasmasheet electrons impacting the lunar surface.\nThus we should expect the level of lunar surface charging to vary over the\neighteen-year cycle. The literature contains reports that support this: several\nobservations made during the cycle maximum of 1994-2000 are attributed to\nbombardment and charging of the lunar surface by plasmasheet electrons.

The\nhigh-resolution VLA images show a core-jet structure for the Sy 1.5 nucleus.\nWhile the core has a moderately steep non-thermal radio spectrum (S_\\nu ~\n\\nu^\\alpha; \\alpha_{1.5}^{4.9} \\approx -0.4), the inner kpc region shows a\nsteeper spectrum (\\alpha_{1.5}^{8.4} \\approx -0.9). This latter spectrum is\ntypical of galaxies where energy losses are high, indicating that the escape\nrate of cosmic ray electrons in NGC 5033 is low. The nucleus contributes little\nto the total 1.4 GHz radio power of NGC 5033 and, based on the radio to\nfar-infrared (FIR) relation, it appears that the radio and far-infrared\nemission from NGC 5033 are dominated by a starburst that during the last 10 Myr\nproduced stars at a rate of ~2.8 M_sun/yr, yielding a supernova (type Ib/c and\nII) rate of 0.045 #/yr. This supernova rate corresponds to about 1 SN event\nevery 22 yr. Finally, from our deep 8.4 GHz VLA-D image, we suggest the\nexistence of a radio spur in NGC 5033, which could have been due to a hot\nsuperbubble formed as a consequence of sequential supernova explosions\noccurring during the lifetime of a giant molecular cloud.\n', '[{\"version\":\"v1\",\"created\":\"Mon, 7 May 2007 14:37:33 GMT\"}]', '2019-08-19', '[[\"Perez-Torres\",\"Miguel A.\",\"\"],[\"Alberdi\",\"Antonio\",\"\"]]'),

We show that at\nleast 40% of NGC 6791\'s evolved stars must have lost enough mass on the red\ngiant branch to avoid the flash, and therefore did not convert helium into\ncarbon-oxygen in their core. Such increased mass loss in the evolution of the\nprogenitors of these stars is consistent with the presence of the extreme\nhorizontal branch in the CMD. This unique stellar evolutionary channel also\nnaturally explains the recent finding of a very young age (2.4 Gyr) for NGC\n6791 from white dwarf cooling theory; helium core white dwarfs in this cluster\nwill cool ~3 times slower than carbon-oxygen core stars and therefore the\ncorrected white dwarf cooling age is in fact ~7 Gyr, consistent with the well\nmeasured main-sequence turnoff age. These results provide direct empirical\nevidence that mass loss is much more efficient in high metallicity environments\nand therefore may be critical in interpreting the ultraviolet upturn in\nelliptical galaxies.\n', '[{\"version\":\"v1\",\"created\":\"Mon, 7 May 2007 22:17:16 GMT\"},{\"version\":\"v2\",\"created\":\"Fri, 20 Jul 2007 22:33:48 GMT\"},{\"version\":\"v3\",\"created\":\"Thu, 4 Oct 2007 19:27:52 GMT\"}]', '2010-02-18', '[[\"Kalirai\",\"Jasonjot S.\",\"\"],[\"Bergeron\",\"P.\",\"\"],[\"Hansen\",\"Brad M.

Second, we define\nnew metrics for similarity in user interest and use these metrics to uncover\nthe structure of the tagging communities we study. The structure we uncover\nsuggests a clear segmentation of interests into a large number of individuals\nwith unique preferences and a core set of users with interspersed interests.\nFinally, we offer preliminary results that demonstrate that the interest-based\nstructure of the tagging community can be used to facilitate content usage as\ncommunities scale.\n', '[{\"version\":\"v1\",\"created\":\"Mon, 7 May 2007 23:57:46 GMT\"},{\"version\":\"v2\",\"created\":\"Mon, 11 Jun 2007 19:38:28 GMT\"},{\"version\":\"v3\",\"created\":\"Thu, 14 Jun 2007 19:44:46 GMT\"},{\"version\":\"v4\",\"created\":\"Sun, 24 Jun 2007 05:24:07 GMT\"}]', '2007-06-24', '[[\"Santos-Neto\",\"Elizeu\",\"\"],[\"Ripeanu\",\"Matei\",\"\"],[\"Iamnitchi\",\"Adriana\",\"\"]]'),
