A method and an apparatus of constructing hybrid Automatic Repeat reQuest systems using specific properties of the BCJR error correcting algorithm. The sulfosuccinamates according to the invention exhibit excellent detergency when employed in formulations used as hard surface cleaners, laundry detergents, and dishwashing liquids. , osteoporosis and other disorders of bone metabolism, cancer, viral infections, and the like. The discharge opening may be sewn shut via a tear seam to ensure that the discharge opening is properly positioned when the tear seam opens to release inflation gas. The reflected pulse is detected at one or more detectors and a pulse characteristic of the pulse and a second value representative of when the reflected pulse arrived at the detector are recorded. Microarrays containing \u201cpregnancy signature\u201d genes or corresponding polypeptides provide another preferred aspect of the invention.
