In this paper, the primary (Josephson-based) and secundary (Zener-based) measurement standard systems used for calibration of solid state voltage standards (Zeners) at Inmetro are described, as well as the calibration method, the related equations and uncertainty budgets.

We introduce a new model for dark energy in the Universe in which a small cosmological constant is generated by ordinary electromagnetic vacuum energy. The corresponding virtual photons exist at all frequencies but switch from a gravitationally active phase at low frequencies to a gravitationally inactive phase at higher frequencies via a Ginzburg– Landau type of phase transition. Only virtual ...

We present the theoretical approach to study the unconventional Josephson junction (uJJ) made by putting the non-superconducting strip on the top of superconducting strip. We work in the framework of the Ginzburg-Landau, Bogoliubov de Gennes and Usadel equations. Then we solve the non-linear partial differential equations numerically for few simple cases. We review the similarities and new aspe...

We consider a system of two coupled ordinary differential equations which appears as an envelope equation in Bose–Einstein Condensation. This system can be viewed as a nonlinear extension of the celebrated model introduced by Landau and Zener. We show how the nonlinear system may appear from different physical models. We focus our attention on the large time behavior of the solution. We show th...

Subjects were asked to carry out a clairvoyance task as a study of the effect of belief and its modulation on psi performance. The task was to guess hidden symbols on Zener cards. Subjects stated whether they believed in the existence of psi, after which the belief was either supported or contradicted by written and verbal arguments. After this, the subjects carried out the clairvoyance task. A...

It is argued that fractional acoustic wave equations come in two kinds. The first kind is constructed ad hoc to have loss operators that fit power law measurements. The second kind is more fundamental as they in addition are based on underlying physical equations. Here that means constitutive equations. These equations are the fractional Kelvin‐Voigt and the more general fractional Zener stress...
