The invention provides isolated nucleic acids molecules, designated BAL nucleic acid molecules, which are differentially expressed in non-Hodgkin’s lymphoma. Based on the calculation result, timing of reading image signals from an image sensing device is controlled. If the monitored parameters are abnormal, then the control unit controls suspension elements on the vehicle to adjust the ride height of the vehicle and subsequently the alignment of the drive train, for example, the operating angle of the driveshaft.
