#### The detection of nuclear quadrupole **resonance** signals with limited data

The denoising method of the pulse nuclear quadrupole **resonance** (NQR) signals was investigated for the case of the small signal to noise ratio. The maximum entropy method of the autoregressive model was applied for the analysis of the experimental NQR data. The obtained results show the efficiency of proposed ...

#### Theatrical interpretation of a literary work from the standpoint of semiotic creativity

... parts of a unique communicative space. These parts may be specified as the original communicative situation and the ‘derivatives’ characterized by semiotic creativity of their authors — the playwright and the directors. The concept of semiotic **resonance** is used as a tool that can help to deepen the analysis of the meaning construction in the heterogeneous discourse of drama. Semiotic **resonance** is understood as the correlations of recurrently used signs accompanied by the amplification of meaning ...

#### Side **resonances** in diamond: influence of isotopic substitution of carbon

We discuss the structure of optically detected magnetic **resonance** (ODMR) spectra of diamond crystal. We propose the new approach to the calculation of hyperfine interaction in composed system, consisted of negatively charged nitrogen-vacancy (NV) center and nearby C13 nuclear spin. Energy levels, rule selection ...

#### Improving the efficiency of wavelet signal processing of NQR signals with modified Morlet basis functions

In this work it is shown that application of the modified function of Morle as basic function of wavelet-transformation has allowed α to achieve by a choice of optimum parameter increase in the permission of the non-stationary signals of magnetic **resonance**, essential localization separate a component of a multicomponent signal and to raise the accuracy of definition of spectral parameters strongly noisy signals.

#### Side **resonances** in diamond: Impact of hyperfine and nuclear quadrupole interactions

The structure of optically detected magnetic **resonance** spectra of diamond crystal is examined. It is shown that in the absence of external magnetic field the hyperfine structure of side **resonances** caused by the hyperfine interactions and is not influenced by the nuclear quadrupole interaction.

#### Geometrical phase of NQR signals

The non-cyclic geometric phase of nuclear quadrupole **resonance** (NQR) signals, which is induced by the trajectory of nuclear magnetization motion upon the external pulse r. f. excitation, was studied. Analytical expressions for the geometric phases of NQR signals were obtained for the case of nuclei with ...
