In this paper, we present a practical end-to-end video transmission system with refined rate allocation at the server and adaptive playback adjustment at the client that enables High Definition (HD) video streaming via bandwidth-constraint IP network. A transmission rate is determined by a rate control algorithm which employs the Program Clock References(More)
In the title heterotrinuclear coordination compound, [CaCu(2)(C(9)H(4)NO(5))(2)(C(3)H(4)N(2))(2)(H(2)O)(3)]·7H(2)O, the Ca(2+) cation is in a penta-gonal-bipyramidal geometry and bridges two (1H-imidazole)[2-(oxaloamino)benzoato(3-)]copper(II) units in its equatorial plane. Each Cu(II) atom has a normal square-planar geometry. The mol-ecule has approximate(More)
In the title coordination polymer, {[BaCu(2)(C(9)H(4)NO(5))(2)(C(3)H(4)N(2))(2)(H(2)O)(4)]·2H(2)O}(n), the Ba(2+) cation is deca-coordinate, ligated by four aqua ligands and four [Cu(C(9)H(4)O(5)N)(C(3)H(4)N(2))] 'complex ligands'. The Cu(II)-containing complex-ligands are bridged by the Ba(2+) cations, resulting in a one-dimensional polymeric chain(More)
The title compound, (C(12)H(10)BrFN)[Ni(C(3)S(5))(2)], is an ion-pair complex consisting of N-(2-fluoro-4-bromo-benz-yl)pyridinium cations and [Ni(dmit)(2)](-) anions (dmit = 2-thioxo-1,3-dithiole-4,5-dithiol-ate). In the anion, the Ni(III) ion exhibits a square-planar coordination involving four S atoms from two dmit ligands. In the crystal structure, weak(More)
OBJECTIVE To observe the repair effect of Schwann cells (SCs) modified by microgene pSVPoMcat on injured spinal cord in rats. METHODS Semi-transection injury at the level of T(8) of spinal cord was made with cutting method on 120 Sprague Dawley (SD) rats. Then 40 rats implanted with SCs modified by microgene pSVPoMcat were taken as Group A, 40 rats(More)
