Described herein is a disk drive balance plug that includes a substantially cylindrical body defining a first end, a second end, a substantially cylindrical outer surface, and a plug central axis. In some embodiments, strip detectors can be provided that can lead to significant cost benefits as compared to existing detectors, such as existing nuclear detectors. In certain example embodiments, a vacuum insulating glass unit is provided. If so, replacement of the entire sub-system is undertaken, and the data bank is updated. The method may include updating values of tap coefficients of the DFE based on the error signal and the estimates of transmitted symbols. The therapeutic composition can comprise an elastin stabilization agent, a collagen stabilization agent, or a combination thereof and be applied to the pericardium, to the outer surface of the myocardium, or a combination thereof using a catheter type of device with an attached reservoir.
