Various methods and devices for replacing damaged, injured, diseased, or otherwise unhealthy posterior elements, such as the facet joints, the lamina, the posterior ligaments, andor other features of a patient’s spinal column, are provided. The described apparatus configures the physical and virtual resources that run on the converged infrastructure to communicate with the rest of the data center. A terminal receives an assignment of a control channel used to send reports and determines a reporting format to use based on the assignment. The outer wall curves inwardly towards the inner wall and then turns back away from the inner wall to form an arcuate protrusion that extends into the exhaust gas flow path forming an aerodynamic throat. Analog beamforming coefficients are constructed by performing an iterative beam acquisition process based on beam search training, and determining optimized beamforming weighting coefficients based on the iterative beam acquisition process.
