A technique, as well as select implementations thereof, pertaining to dual receive processing in wireless communications is described. A reverse-time data process is applied to the synchronized array measurements to obtain a plurality of dynamic particle parameters associated with subsurface locations. The surface treatment carried out on the implant includes low temperature anodic treatment of the substrate in a phosphorus-containing solution, such as a phosphate-containing solution. A side portion of the drive nut is deformed to retain the drive nut on the screw against the nut.
