Inverted metamorphic multijunction solar cells having a heterojunction middle subcell and a graded interlayer, and methods of making same, are disclosed herein. The tilt is induced by epitaxial growth of the hcp Co alloy on an obliquely evaporated nonmagnetic polycrystalline underlayer, so that the magnetic recording medium exhibits thermal stability and improved overwrite with a single pole-type head. A flex line is formed between the ends of the curved slit, the curved slit and the flex line together defining a valve actuation area. Such a gas discharge panel can deliver excellent display performance. This prevents short-circuiting between the bump electrodes which is caused by oversupplying the low-melting metallic members between the adjacent bump electrodes. The method includes assigning a first cell of a first network node to a first timing advance group of a user equipment and assigning a second cell of a second network node to a second TAG of the UE, wherein the second network node has a separate MAC scheduler from the first network node, and wherein the UE is able to transmit data on both the first and the second cell.
