Methods and compositions are provided for the direct catalytic asymmetric aldol reaction of aldehydes with donor molecules selected from ketones and nitroalkyl compounds. The vertical transistors are arranged in an alternating gate-facing orientation, with a common source formed on a first end and separate drains on their second ends. The shoulder harness features retractable shoulder straps that may be used to securely extend the detachable adjustable pouch system away from wearer without having to detach the pouch or remove the infant while simultaneously allowing the wearer face to face access with the infant. The demodulator is configured to demodulate the filtered receiver detect signal and produce a recovered receiver detect signal that is indicative of whether a receiver is electrically coupled to the data port. Two opposed longitudinal edges define the leading surface, with at least one of the edges being outwardly flared. The methods provide a ruthenium layer having good adherence to an underlying high dielectric layer while providing good step coverage over structures on the substrate.
