Low-frequency active noise control of an underwater large-scale structure with distributed giant magnetostrictive actuators [PDF]
A light and thin underwater large-plate active acoustic structure is developed that satisfies the particular requirements of high pressure resilience, low frequency and high efficiency encountered in underwater work environments.

Map of low‐frequency electromagnetic noise in the sky [PDF]
AbstractThe Earth's natural electromagnetic environment is disturbed by anthropogenic electromagnetic noise. Here we report the first results from an electromagnetic noise survey of the sky. The locations of electromagnetic noise sources are mapped on the hemisphere above a distributed array of wideband receivers that operate in a small aperture ...

Analyzing the impact of time-correlated noise on zero-noise extrapolation [PDF]
Zero-noise extrapolation is a quantum error mitigation technique that has typically been studied under the ideal approximation that the noise acting on a quantum device is not time-correlated. In this work, we investigate the feasibility and performance of zero-noise extrapolation in the presence of time-correlated noise.

Low-Frequency Noise Phenomena in Switched MOSFETs [PDF]
In small-area MOSFETs widely used in analog and RF circuit design, low-frequency (LF) noise behavior is increasingly dominated by single-electron effects.

Active noise cancellation of low frequency noise propagating in a duct
Aims: The object is to find a manner of reduction primary noise from a source by an electro acoustic device that cancels unwanted sound by generating an anti sound (anti noise) of equal amplitude and an opposite phase is described as an active noise ...

Noise characterization of an atomic magnetometer at sub-millihertz frequencies [PDF]
Noise measurements have been carried out in the LISA bandwidth (0.1 mHz to 100 mHz) to characterize an all-optical atomic magnetometer based on nonlinear magneto-optical rotation.
