The invention relates to neublastin neurotrophic factor polypeptides, nucleic acids encoding neublastin polypeptides, and antibodies that bind specifically to neublastin polypeptides, as well as methods of making and methods of using the same. The method includes deriving a vectorcardiogram from implanted electrodes, analyzing the D-VCG, deriving optimal CRT pacing parameters from the analysis of the D-VCG, and adjusting the CRT pacemaker according to the derived parameters. A first value representing a benefit for analyzing the first packet for intrusions in relation to a cost for analyzing the first packet for intrusions is automatically determined. A disposable absorbent garment includes an outer cover, a body-side liner, and an absorbent composite such as that described above. A rank can be assigned to each of the first portion of banks and a candidate set of banks chosen from the first portion of banks.
