Delay lines include an adjustable delay cell that adjusts a speed at which an input signal to the adjustable delay cell is transmitted through the adjustable delay cell responsive to a control signal. The use of labels is not required and the methods can be performed in a high-throughput manner. During operation the tab is moved downwardly from a disengaged position into contact with the sidewall of the stud. The data compressor compresses input data so as to obtain compressed data. % 2-ring MDI are determined analytically; and an acidic compound is added to the fraction containing at least 5 wt. The suture attachment to the bone anchor involves the looping of a substantial length of suturing material around a shaft of the anchor, thereby avoiding an eyelet connection which requires a knot and which concentrates stress on a very small portion of the suturing material.
