Magnetic resonance is a widely established phenomenon that probes magnetic properties such as damping and anisotropy. Even though the typical frequency of magnet ranges from gigahertz to terahertz, experiments also report near zero in large class magnets. Here we revisit this by analyzing symmetry system find $\ensuremath{\omega}$ follows universal power law $\ensuremath{\omega}\ensuremath{\pro...

Abstract We propose a method to distinguish between trivial and topological, Majorana, zero-energy states (ZESs) in both short long superconductor-normal-superconductor junctions based on Rashba nanowires using phase-biased equilibrium transport measurements. In particular, we show how the sawtooth profile of supercurrent, due Majorana oscillation suppression topological phase for sufficiently ...

An efficient and low complexity frequency estimation method based on the discrete Fourier transform (DFT) samples is described. The suggested method can operate with an arbitrary window function in the absence or presence of zero-padding. The frequency estimation performance of the suggested method is shown to follow the Cramer-Rao bound closely without any error floor due to estimator bias, ev...

Missing samples in the time domain introduce noise-like artifacts in the ambiguity domain due to their de facto zero values assumed by the bilinear transform. These artifacts clutter the dual domain of the time-frequency signal representation and obscures the time-frequency signature of single and multicomponent signals. In order to suppress the artifacts influence, we formulate a problem based...

This article is a critical review of some of the methods that have been used for the sampling, analysis, and monitoring of vapor-phase toluene diisocyanate (TDI). Only some of the methods that have received relatively widespread application have been addressed in this article. This review includes a "tutorial style" discussion of basic definitions and basic principles and procedures of quality ...
