A waveform equalizer is designed to perform high frequency enhancement on a read signal without increasing inter symbol interference even when the shortest run length of the read signal is not greater than twice the clock period of the channel clock signal. The device is deployed by connecting the sheave wheel assembly to a rigid dolly arm with an adjustable tension rod to relieve a gooseneck from adverse tensile, compressive and bending forces from the movement of a wireline through the sheave assembly. This high prevalence of NMD-targeted transcripts indicates a systemic way of regulating gene expression\u2014by shunting gene expression to nonproductive splice variants. The wavelength conversion laser outputs converted wavelength light having a broad spectral width and low coherency, thereby enabling it to carry out highly efficient and stable high-output oscillation.
