The\nrunning coupling corrections calculated recently significantly change the shape\nof the scaling function as compared to the fixed coupling case leading to a\nconsiderable increase in the anomalous dimension and to a slow-down of the\nevolution with rapidity. The difference between the two recent calculations is\ndue to an extra contribution to the evolution kernel, referred to as the\nsubtraction term, which arises when running coupling corrections are included.\nThese subtraction terms were neglected in both recent calculations. We evaluate\nnumerically the subtraction terms for both calculations, and demonstrate that\nwhen the subtraction terms are added back to the evolution kernels obtained in\nthe two works the resulting dipole amplitudes agree with each other! We then\nuse the complete running coupling kernel including the subtraction term to find\nthe numerical solution of the resulting full non-linear evolution equation with\nthe running coupling corrections. Again the scaling regime is recovered at very\nlarge rapidity.\n', '[{\"version\":\"v1\",\"created\":\"Wed, 4 Apr 2007 16:54:26 GMT\"},{\"version\":\"v2\",\"created\":\"Fri, 22 Jun 2007 18:56:47 GMT\"}]', '2008-11-26', '[[\"Albacete\",\"Javier L.\",\"\"],[\"Kovchegov\",\"Yuri V.\",\"\"]]'),

We find that\nthe outflows tend to escape to low density regions, and hardly affect the dense\nfilaments visible in HI absorption. As a result, the strength of HI absorption\nnear galaxies is not reduced by galactic winds, but even slightly increases. We\nalso find that a lack of HI absorption for lines of sight (LOS) close to\ngalaxies, as found by Adelberger et al., can be created by hot gas around the\ngalaxies induced by accretion shock heating. In contrast to HI, metal\nabsorption systems are sensitive to the presence of winds. The models without\nfeedback can produce the strong CIV and OVI absorption lines in LOS within 50\nkpc from galaxies, while strong SN feedback is capable of creating strong CIV\nand OVI lines out to about twice that distance. We also analyze the mean\ntransmissivity of HI, CIV, and OVI within 1 h$^{-1}$ Mpc from star-forming\ngalaxies. The probability distribution of the transmissivity of HI is\nindependent of the strength of SN feedback, but strong feedback produces LOS\nwith lower transmissivity of metal lines. Additionally, strong feedback can\nproduce strong OVI lines even in cases where HI absorption is weak.
