Systems and methodologies are described that facilitate providing uplink inter-cell interference cancellation. Methods for using compounds that inhibit human DNA ligases to provide insights into the reaction mechanisms of human DNA ligases, for example to identify the human DNA ligase involved in different DNA repair pathways. The base arm extends up to a lateral knee extension where a reverse arm continues from the base arm back in direction towards a central axis of the column. The one or more graphene capacitors can be configured to provide for smoothing of the signalling provided to the output. The oscillator includes; a bias circuit for producing a bias signal for the transistor, said bias circuit including an amplifier coupled to the output electrode of the transistor; and a circuit coupled between an output of the amplifier and a control electrode of the transistor, for isolating the bias signal provided by the amplifier from the oscillating signal. A first connector is attached to the first terminal, and has a plurality of contact parts to contact the conductor layers.
