The quantum speed limit time for system under squeezed environment is studied. We consider two typical models, the damped Jaynes–Cummings model and dephasing model. For environment, we find that becomes larger with parameter r increasing indicates symmetry about phase value ? = ? . Meanwhile, can also be influenced by coupling strength between environment. However, determined rate boundary of a...

Two experiments are described that are designed to investigate what determines the maximum spatial displacement detectable sdmaxd for spatially broadband patterns exposed in a two-frame motion sequence. In experiment 1, dmax was found to be 1.63 times greater for a two-dimensional (2-D) broadband random pattern with a 1yf Fourier amplitude spectrum (equal contrast in each octave) than for a 2-D...

honey is the oldest natural food produced by honeybee and comprises wide variety of valuable ingredients including carbohydrate, proteins, minerals, vitamins, organic acids, polyphenols and flavonoids that contribute to well-known therapeutic properties. this review provide available scientific information on different ways of honey adulteration and chemical contamination with the certain focus...
