1. IntroductionThe availability of exact solutions to field theories, both classical and quantum, is important to a general understanding of these theories. Such solutions are very rare and, in most cases, are for unphysical situations. The harnessing of the functional renormalization group can help to mitigate such a limitation significantly [1,2,3]. Still, explicit solutions are not provided in this way. Recently, an exact solution to some quantum field theory was proposed [4,5].

Abstract:Ultrasonic signals can be conveniently recorded using modern high-speed analog-to-digital converters and analyzed through digital signal processing algorithms. Sometimes, in some applications, such as in bioacoustics, it is necessary to convert digital data to analog signals with a special transformation that allows compressing and translating the spectrum toward audible frequencies.
