Disclosed are novel peptides including antiarrhythmic peptides that have improved stability. The method further comprises suspending the program operation in the middle of the program operation, and after suspending the program operation, resuming the program operation in response to a resume command. The use of common objects providing robust functionality while being insulated from the specific platforms used to implement the workflow processing system enable the common objects to be reused to perform many functions in many different lines of business without modification. The refractive index sensitivity is substantially increased, because of the high Q-value of the optical microcavity. The injector also includes a groove formed in the surface, the groove surrounding the injector hole. This configuration provides more effectively exerted positioning effects for a virtual sound source realized by using the three speakers, especially for the effects in a frontward field of sound.
