A nuclear quadrupole resonance thermometer with frequency locking
TLDR
In this paper, a precision thermometer using the NQR absorption of KC10 3 has been developed, where the super-regenerative oscillators with frequency locking has been used as the sensor oscillator in order to avoid the defects of the conventional SRSO.About:

Structural and functional synthesis of the continuous wave NQR temperature sensor with increased conversion linearity.
TL;DR: It is experimentally established that at amplitude modulation of 40% and change of input voltage in the range of 20-1000 mV, the circuit of a symmetric marginal oscillator with a linear active demodulator provides better linearity of transfer characteristic than the circuits of asymmetricmarginal oscillators with JFET or diode detectors.

TL;DR: In this paper, an apparatus for exciting and detecting NQR in a substance containing quadrupole nuclei responsive to the nQR phenomenon is described. But the apparatus is not suitable for the detection of NQRs.

Sensitivity of NQR spectroscopy in the research of physical and chemical properties of copper-bearing minerals
TL;DR: In this paper, the authors proposed a method to identify the most likely candidate regions of a region in the world to be affected by cyber-attacks, and showed that 10% of the regions were located in the region of South-West Asia.
