The present disclosure relates to lipoprotein complexes and lipoprotein populations and their use in the treatment andor prevention of dyslipidemic diseases, disorders, andor conditions. An apparatus in accordance with one embodiment is directed to an aircraft system that includes an airfoil having first and second oppositely facing flow surfaces and a tip. The HeNB can additionally or alternatively register its location or other location parameters with a positioning server for subsequent provisioning as assistance information for determining a device position. The start-up circuit includes at least one switch arranged to connect at least one current source to at least one of the inputs of the operational amplifier during the start-up phase, and to disconnect the at least one current source from the at least one of the inputs of the operational amplifier after the start-up phase.
