We present the first calculation of the }4 Wigner–Kirkwood corrections to a relativistic system of fermions in the presence of external scalar and vector potentials. The method we propose allows the efficient computation of semiclassical corrections to one-body operators such as mean energies and local densities. It also preserves gauge invariance and produces explicitly convergent results desp...

A dielectric measurement for the aqueous solutions at lower frequencies (20Hz to 2MHz) has been carried out in frequency domain using Agilient Precision LCR meter (E4980A). The dielectric permittivity spectra of over entire concentrations with aqueous solutions are measured at 25 ̊C. From observed spectra, static dielectric constants (ε0) have been determined. Dielectric Spectroscopy is especial...

Introduction Profitability in the swine industry is based on prolificacy. One measurement of prolificacy is the number of piglets produced per year. To optimize prolificacy and profits it is essential that sows are re-bred as soon as possible after weaning. An extended post-weaning anestrus decreases overall productivity and increases costs of production. A large number of sows undergo prolonge...

Fractional Brownian motion (fBm) is a ubiquitous nonstationary model for many physical processes with power-law time-averaged spectra. In this paper, we exploit the nonstationarity to derive the full spectral correlation structure of fBm. Starting from the time-varying correlation function, we derive two different time-frequency spectral correlation functions (the ambiguity function and the Kir...

We provide an in-depth study of the recently introduced notion completely incompatible observables and its links to support uncertainty Kirkwood–Dirac nonclassicality pure quantum states. The latter has been proved central a number issues in information theory metrology. In this last context, it was shown that advantage requires use nonclassical establish sharp bounds very general validity impl...

The 7-tesla acquisitions, facilitated by the use of a customized radiofrequency coil configuration and cardiac gating, achieved isotropic resolution of 6 mm, reported researchers from the Berlin Ultrahigh Field Facility (BUFF) in Berlin, along with co-authors from other institutions including Charité University Medicine in Berlin, the German Cancer Research Center in Berlin, and the University ...
