Fig 1. This basic VCO/waveform generator IC circuit includes a voltage follower loop (formed with IC1) and symmetry feedback loop (IC3) to eliminate an asymmetric duty cycle, which would cause ...

“There are five fundamental operations in mathematics,” the German mathematician Martin Eichler supposedly said. “Addition, subtraction, multiplication, division and modular forms.” Part of the joke, ...

Non-parametric procedures, based on the empirical characteristic function, are proposed for estimating the centre δ of a symmetric distribution and for testing the hypothesis of symmetry around an ...

In this paper we treat the problem of finding all the domains in C for which the uniform distance from the function z̄ to the space of analytic functions is equal precisely to (2 area/perimeter). We ...

These stock images illustrate brain asymmetry between the left and right cerebral hemispheres of the cerebrum. Source: Semnic/Shutterstock Neuroscientists have identified intriguing symmetry and ...
