Synchronization in an optomechanical cavity.

We study self-excited oscillations (SEO) in an on-fiber optomechanical cavity. Synchronization is observed when the optical power that is injected into the cavity is periodically modulated. A theoretical analysis based on the Fokker-Planck equation evaluates the expected phase space distribution (PSD) of the self-oscillating mechanical resonator.

Molecular shift register and its utilization as an autonomous DNA synthesizer.

A novel algorithmic approach to the synthesis of fairly long DNA molecules with nonrecurring sequences is demonstrated. The scheme exploits chemical embodiment of shift registers (SR) to execute algorithms similar to those used to generate pseudorandom numbers on a computer. Single stranded DNA molecules guide the synthesis of double stranded DNA according to the SR truth table.
