Systems and methods for enhancing the stability of a mode-locked laser’s output are disclosed. More particularly, the invention relates to polypeptides derived from aprotinin and from aprotinin analogs as well as conjugates and pharmaceutical compositions comprising these polypeptides or conjugates. The weak organic acid preferably has a pKa high enough to avoid Cu etching but is sufficiently acidic to remove copper oxide at a rate that is compatible with high throughput manufacturing. Also, the plurality of differential transmission lines are arranged such that alternating current directions substantially eliminate cross-talk across the plurality of pairs of differential transmission lines. The processing circuitry is also configured to, responsive to the discovery cell identifier matching the physical cell identifier, identifying that the base station is active or in coverage. The device provides for transferring cigarettes from a cartridge supporting them to a package.
