Stochastic disturbances and spikes (sudden sharp fluctuations of any system parameter), commonly observed among natural and laboratory-scale systems, can perturb the multistable dynamics significantly and become a serious impediment when the device is designed for a certain dynamical behavior. We experimentally demonstrate that suitable periodic modulation of any system parameter may efficientl...

It is argued that immense physical resources – for nonlocal communication, espionage, and exponentially-fast computation – are hidden from us by quantum noise, and that this noise is not fundamental but merely a property of an equilibrium state in which the universe happens to be at the present time. It is suggested that ‘non-quantum’ or nonequilibrium matter might exist today in the form of re...

NOISE SAMPLING AND CONTROL STRATEGIES IN THE HOSPITAL ENVIRONMENT by Rosarito M. Guerrero Noise in the hospital environment can have negative effects on both patients and hospital staff. Unwanted noise can be disturbing and often annoying thus, interfering with patients' sleep and obstructing work performance of the hospital staff. A research study was conducted in the hospital unit to identify...

For the past fifty years the question of nature has been conspicuously absent from urbanistic discourse... The development of the American city can be explained through the opposition between nature and culture, wilderness and city. Diana Agrest, 1996 From the Greek for study of the house, ecology refers to the relationships (or the study thereof) between organisms and their physical environmen...
