The Altmetric Attention Score is a quantitative measure of the attention that a research article ... using the finite pulse radio frequency driven recoupling (fpRFDR) at high MAS frequencies of 40–60 ...

Scientists have developed a groundbreaking quantum interferometry tool that achieves nanometer-scale precision in challenging ...

Continuous infrasound (low-frequency acoustic energy) monitoring is now established in Yellowstone. And the method is ...

Abstract: This paper describes the design and implementation of an instrument for the measurement of the instantaneous frequency of a signal. It is based on the extensive use of signal processing ...

Researchers from the University of Rochester and University of California, Santa Barbara, engineered a laser device smaller ...

Kinetics of ferrocyanide electrooxidation was investigated by nonlinear frequency response analysis (NLFRA) of current output to the sinusoidal large-amplitude potential perturbation input. The aim ...

Frequency Exchange is now ranked among the top 10 undervalued stocks in the Medical Devices & Instruments industry on the Toronto Stock Exchange or TSX Venture Exchange. A stock is considered ...

The clock relies on cesium atoms, which oscillate between quantum states at a frequency of over 9 billion times per second. NIST-F4 uses lasers to cool a ball of cesium atoms to near absolute zero, ...

Abstract: A photonic-assisted approach for ultra-wideband frequency measurement based on stimulated Brillouin scattering and a chirped optical pulse sequence was proposed. The system leverages the ...

After achieving stable locking of both lasers, the 423 nm laser serves as the shelved readout for population measurement and 657 nm clock signal detection. Figure 3 illustrates the schematic of the ...
